Description

A corn wide and narrow row fertilization and sowing integrated machine

Technical Field

The invention relates to the technical field of corn sowing, and more specifically to a corn wide and narrow row fertilization and sowing integrated machine.

Background Art

The corn fertilization and sowing machine is an agricultural machinery that integrates fertilization and sowing. The fertilization and sowing machine can complete the two tasks of fertilization and sowing at the same time. Specifically, by adding a fertilization device to the machine, when the seeder is driving, the fertilization device will spray the fertilizer at the appropriate depth and distance for plant growth to ensure that the growth needs of corn crops are met. At the same time, seeds and fertilizers are put into the machine at the same time, and they are sent to different nozzles through a special mechanism, and fertilization and sowing are carried out on the same row.

There are many types of integrated corn fertilization and seeding machines, including pneumatic corn seeders: this type of seeding machine is mainly divided into air suction seeding machines, air pressure seeding machines and air blowing seeding machines. Among them, the air suction seeding machine is the most common, which uses an air suction vertical disc to form a vacuum environment. Through the rotation of the seed disc, the corn seeds are adsorbed one by one into the seeding slot of the seed disc, and the excess seeds are scraped off by the scraper to ensure that only one seed is left in each gap, so as to achieve the purpose of saving seeds.

At present, in the existing relevant technical solutions, the following problems exist during the use of the integrated fertilization and seeding machine: since the size of the seeding trough cannot be adjusted, during the rotation of the seeding disk, batches of seeds are adsorbed into the seeding trough one by one through the adsorption force in the seeding device, but since the sizes of corn seeds are different, it may cause the corn seeds to be adsorbed into the seeding trough. After being adsorbed into the seeding trough, larger corn seeds may be stuck in the seeding trough, making it impossible for the seeding trough with the stuck corn to repeatedly transport the corn seeds, further resulting in uneven spacing between corn seeds, resulting in problems such as reduced corn yields.

Summary of the invention

In view of the deficiencies in the prior art, the object of the present invention is to provide a corn wide and narrow row fertilization and sowing all-in-one machine.

To achieve the above-mentioned purpose, the present invention provides the following technical solutions, including: a fertilizing and sowing machine, a seed pushing mechanism and a seed screening mechanism towed on an agricultural four-wheel vehicle;

The seed pushing mechanism includes a funnel and a seed divider installed on the fertilizing and sowing machine, a feeding pipe is arranged between the funnel and the seed divider, the top of the feeding pipe is fixedly connected with the bottom of the funnel, the bottom of the feeding pipe penetrates into the seed divider, and the outside of the feeding pipe is fixedly connected with the seed divider, and the inside of the seed divider rotates to make the corn seeds in the funnel fall into the seed divider through the feeding pipe;

The seed pushing mechanism also includes a seed pushing assembly, which is fixedly installed in the seed sorter. The seed pushing assembly at least includes a push plate that can move back and forth, and a push rod is fixedly connected to the push plate. When the seed sorting disk inside the seed sorter rotates, the push plate drives the push rod to move into the seed sorting slot, so that the push rod pushes the corn seeds in the seed sorting slot out.

The seed screening mechanism is fixedly installed in the seed sorter. When corn seeds fall from the hole into the seed sorter through the feeding pipe, the screening mechanism is used to screen the fallen corn seeds so that the damaged corn seeds can be collected in a centralized manner.

The transmission component is fixedly mounted on the seed sorting disk, and a screening piece is fixedly connected to the transmission component. A plurality of screening slots are provided on the screening piece. The screening frame is fixedly connected to the inner wall of the seed sorter. The screening frame is used to place corn seeds. A control slot is provided on the inner arc of the screening frame. The screening piece swings in the screening frame through the control slot, and the corn seeds are screened during the swinging process of the screening piece.

Preferably, the transmission component includes a driving tooth and a driven tooth, the driving tooth is fixedly connected to the power output end of the seed sorting disk, and the driven tooth is fixedly connected to the top of the screening element. When the seed sorting disk rotates, the driving tooth rotates synchronously, and the driven tooth rotates, and the driven tooth further drives the screening element to swing in the screening frame, so that the damaged corn seeds move from one side of the screening element to the other side through the screening slot.

Preferably, the screening component also includes a collecting part, which includes a waste trough and a collecting box opened on the outer arc of the screening frame. The opening of the waste trough is fixedly connected to a waste pipe, the bottom of the waste pipe passes through the outside of the seed sorter, and the collecting box is fixedly connected to the bottom of the seed sorter.

The nutrient solution in the drip irrigation barrel flows to the farmland through the drainage hole, so that the corn absorbs nutrients in the nutrient solution.

Compared with the prior art, the present invention has the following beneficial effects:

1. Through the seed pushing mechanism arranged inside the seed separator, after the corn kernels are sucked into each seeding slot by the suction system, the control disk in the seed pushing mechanism rotates, so that the roller drives the positioning column to move back and forth in the same straight line, so that the push plate drives the push rod to continuously enter and extend into the seeding slot, further effectively pushing out the corn seeds in the seeding slot, so that the corn seeds are buried in the soil along the sowing pipe, thereby effectively avoiding the problem of corn seeds being stuck in the seeding slot and unable to be sown normally, which affects the problem of corn yield reduction.

2. By setting up a seed screening mechanism to cooperate with the seed pushing mechanism, during the corn sowing process, the screening parts in the seed screening mechanism can continuously swing in the screening frame, thereby screening out the damaged corn seeds in the screening frame, and the damaged corn seeds are dropped into the collection box through the waste trough and the waste pipe to be collected centrally, further eliminating the problem that the damaged corn seeds are sown in the soil but cannot grow normally, thereby causing a reduction in corn yield.

DETAILED DESCRIPTION

1 to 15 , an embodiment of a corn wide and narrow row fertilizing and sowing integrated machine of the present invention is further described.

A corn wide and narrow row fertilization and sowing integrated machine, comprising: a fertilization and sowing machine 1 towed on an agricultural four-wheel vehicle, a seed pushing mechanism 2 and a seed screening mechanism 3;

The seed pushing mechanism 2 includes a funnel 211 and a seed divider 212 installed on the fertilizer seeder 1, and a feed pipe 213 is provided between the funnel 211 and the seed divider 212. The top of the feed pipe 213 is fixedly connected to the bottom of the funnel 211, and the bottom of the feed pipe 213 penetrates into the seed divider 212, and the outside of the feed pipe 213 is fixedly connected to the seed divider 212. The seed divider 212 rotates internally to make the corn seeds in the funnel 211 fall into the seed divider 212 through the feed pipe 213;

The seed pushing mechanism 2 also includes a seed pushing component, which is fixedly installed in the seed separator 212. The seed pushing component at least includes a reciprocating push plate 221, and a push rod 222 is fixedly connected to the push plate 221. When the seed separation disk 214 inside the seed separation device 212 rotates, the push plate 221 drives the push rod 222 to move into the seed separation groove 215, so that the push rod 222 pushes the corn seeds in the seed separation groove 215 out;

The seed screening mechanism 3 is fixedly installed in the seed sorter 212. When the corn seeds fall from the hole into the seed sorter 212 through the feeding pipe 213, the screening mechanism is used to screen the falling corn seeds so that the damaged corn seeds can be collected.

The seed pushing assembly also includes a driving assembly, a concave part 223 and a return spring 224. The driving assembly is fixedly installed on the concave part 223 and the seed dividing disk 214. The driving assembly causes the concave part 223 to reciprocate. A slide groove 225 is fixedly connected to the concave part 223. A slide bar 226 is slidably connected in the slide groove 225. A right-angle plate 227 is fixedly connected to the bottom of the slide bar 226. A side plate 228 is fixedly connected to the bottom of the right-angle plate 227. The side plate 228 is fixedly connected to the inner wall of the seed dividing device 212. When the concave part 223 drives the push plate 221 and the push rod 222 to reciprocate, the slide groove 225 and the slide bar 226 limit the moving trajectory of the concave part 223. The return spring 224 is fixedly connected between the push plate 221 and the side plate 228.

The driving assembly includes a driven component and a control disk 230. The driven component is fixedly connected to the side of the inner concave part 223 away from the slide groove 225. The control disk 230 is fixedly installed on the side of the seed sorting disk 214 close to the side plate 228. A wave groove 231 is opened on the control disk 230. The driven component slides in the wave groove 231. When the seed sorting disk 214 rotates, the control disk 230 rotates synchronously, and the driven component reciprocates along the trajectory of the wave groove 231.

The driven component includes a positioning rod 232, one end of which is fixedly connected to a side of the inner concave plate away from the slide groove 225, and the other end of the positioning rod 232 extends into the inside of the wave groove 231. The outside of the positioning rod 232 is movably connected to a roller 233, and the roller 233 is rotatably connected to the wave groove 231. When the control plate 230 rotates, the roller 233 drives the positioning rod 232 to reciprocate along the track of the wave groove 231;

The fertilizing part of the fertilizing and seeding machine 1 is a prior art and only needs to be used in conjunction with the seeding part;

1 to 4, the feed pipe 213 is a hard pipe as a whole, and has a certain hardness. The seed divider 212 is fixedly mounted on the fertilizer seeding machine 1 through the feed pipe 213, so that the seed divider 212 itself is fixed;

The funnel 211 is used to place the corn kernels to be sown, and at the same time, the amount and frequency of the seeds being dropped from the funnel are controlled by the fertilizer sowing machine 1; the upper opening of the funnel 211 is larger than the lower opening, so that the amount of corn seeds dropped can be better controlled, and the corn seeds can be easily dropped into the screening frame 310;

The upper part of the feed tube 213 is a vertical tube, and the lower part is an arc-shaped tube. The opening of the lower part of the feed tube 213 is perpendicular to the opening at the top of the screening frame 310, and the horizontal plane of the bottom opening of the feed tube 213 is 1 to 2 cm lower than the horizontal plane of the bottom of the screening frame 310. The purpose is to prevent the corn seeds from colliding with the inner wall of the screening frame 310 and splashing out of the screening frame 310 when the corn seeds fall into the screening frame 310 through the feed tube 213. The part of the feed tube 213 placed inside the seed separator 212 does not contact the seed separator 214, so as to prevent the seed separator 214 from rotating and rubbing the feed tube 213.

The seed separator 212 is an air-suction seeder in the prior art. When the funnel 211 places the corn seeds in the screening frame 310 through the feeding pipe 213, the seed screening mechanism 3 screens the corn seeds while the seed separation disk 214 rotates. The corn seeds have been screened before sowing. The seed screening mechanism 3 is used to further screen the corn seeds to avoid damage to the corn seeds in the process of placing the screening frame 310 from under the funnel 211, and the shaking caused by the towing four-wheel vehicle in the farmland, which causes the corn in the funnel 211 to be squeezed and damaged. Specifically referring to Figures 3, 4, and 10, the shell part of the seed separator 212 is a hollow cylindrical shape as a whole, and a circular plate with an opening in the center is fixedly connected to the inner wall of the shell, and the opening size of the circular plate is adapted to the outer arc of the seed separation disk 214.

4, the push plate 221 and the screening frame 310 are arranged on both sides of the seed sorting disc 214 in a relative state, and a push rod 222 is fixedly connected to the side of the push plate 221 close to the seed sorting disc 214, and the end of the push rod 222 away from the push plate 221 is set in an arc shape, so that the push rod 222 can smoothly reciprocate in the seed sorting groove 215;

3, 9 and 10, a sowing tube is provided on the end of the push rod 222 away from the push plate 221, and the tube is integrated with the seed separator 212. The push rod 222 extends into the seed separator 215, and the corn seeds are separated from the seed separator 215 and fall into the soil through the sowing tube;

When the seed separation disc 214 rotates, the control disc 230 rotates synchronously. When the control disc 230 rotates, the wave groove 231 provided on the control disc 230 pushes the roller 233 to move back and forth along the track of the wave groove 231, so that the positioning rod 232 drives the push plate 221 on the inner concave plate to move back and forth, and further the push plate 221 drives the push rod 222 to reciprocate in the seed separation groove 215.

When the push rod 222 extends into the seed sorting slot 215, the disc temporarily rotates to push out the corn seeds in the seed sorting slot 215. When the push rod 222 extends out of the seed sorting slot 215, the seed sorting disc 214 continues to rotate to move the seed sorting slot 215 containing corn seeds to a position close to the push rod 222, and reciprocates in sequence to smoothly separate the seeds in the seed sorting slot 215 from the seed sorting slot 215. When the push plate 221 drives the push rod 222 to extend into the seed sorting slot 215, the push plate 221 also simultaneously approaches the side plate 228, and the push plate 221 squeezes the return spring 224. When the push plate 221 moves to the lower side away from the side plate 228, the squeezed return spring 224 extends to assist the push rod 222 to extend out of the seed sorting slot 215.

3, 4, 9 and 12, the hollow shape of the seed separation groove 215 facing the screening frame 310 is semicircular, and this part is used to place corn seeds, and the hollow shape of the seed separation groove 215 facing the push plate 221 is cylindrical, and this part is used for the push tube to extend into the seed separation groove 215 to push out the corn seeds;

The slide bar 226 and the slide groove 225 are used to limit the moving track of the push plate 221, so that the push plate 221 can only reciprocate in a straight line state, thereby preventing the push plate 221 from being skewed during the movement process;

7, the side plate 228 is provided with an opening, and the push rod 222 passes through the side plate 228 through the opening and extends into the seed separation slot 215;

4 and 9 , the number of waves of the wave groove 231 corresponds to the number of the seed sorting grooves 215 , so that during the rotation of the control plate 230 , the wave groove 231 enables the roller 233 to drive the positioning rod 232 to move back and forth, and the push plate 221 can accurately extend into the seed sorting groove 215 every time it approaches the side plate 228 .

The seed screening mechanism 3 includes a screening component, which includes at least a transmission component and a screening frame 310. The transmission component is fixedly installed on the seed sorting disk 214. A screening member 311 is fixedly connected to the transmission component. A plurality of screening slots 312 are provided on the screening member 311. The screening frame 310 is fixedly connected to the inner wall of the seed sorter 212. The screening frame 310 is used to place corn seeds. A control slot 313 is provided on the inner arc of the screening frame 310. The screening member 311 swings in the screening frame 310 through the control slot 313. The corn seeds are screened during the swinging process of the screening member 311.

The transmission component includes a driving tooth 314 and a driven tooth 315. The driving tooth 314 is fixedly connected to the power output end of the seed sorting disk 214, and the driven tooth 315 is fixedly connected to the top of the screening element 311. When the seed sorting disk 214 rotates, the driving tooth 314 rotates synchronously, and the driven tooth 315 rotates. The driven tooth 315 further drives the screening element 311 to swing in the screening frame 310, so that the damaged corn seeds move from one side of the screening element to the other side through the screening slot 312.

The screening component also includes a collecting component, which includes a waste trough 316 and a collecting box 317 opened on the outer arc of the screening frame 310. The opening of the waste trough 316 is fixedly connected with a waste pipe 318. The bottom of the waste pipe 318 passes through the outside of the seed sorter 212. The collecting box 317 is fixedly connected to the bottom of the seed sorter 212. When the damaged corn seeds are screened out by the screening component 311, the synchronous corn seeds fall into the waste pipe 318 through the waste trough 316, and finally the damaged corn seeds fall into the collecting box 317 and are collected in a centralized manner.

3, the side of the screening frame 310 close to the seed sorting plate 214 is open, and the seed sorting plate 214 is fitted with the screening frame 310, so that after the corn seeds are lowered from the funnel 211 and the feeding pipe 213 into the screening frame 310, the corns in the screening frame 310 can enter the seed sorting slot 215 one by one through the rotation of the seed sorting plate 214;

When the external control switch rotates the seed disc 214, the driving gear 314 rotates, and the driven gear 315 rotates, and the driven gear 315 drives the screening element 311 to swing toward the bottom of the feeding tube 213;

Taking the positions of the screening frame 310 and the screening element 311 in Figures 12 and 14 as a reference, the corn in the funnel 211 is lowered to the right side of the screening element 311 through the discharge pipe 213. When the seed separation disc 214 drives the active tooth 314 to rotate counterclockwise and the driven tooth 315 to rotate clockwise, the screening element 311 also swings 70° to 80° clockwise. During the swinging process, the screening element 311 gradually moves away from the left inner wall of the screening frame 310. At this time, some damaged seeds gradually fall to the left side of the screening element 311 through the screening slot 312, and roll into the collection box 317 from the waste slot 316 along the inner wall of the screening frame 310. When the active tooth 314 is separated from the driven tooth 315, the driven tooth 315 and the screening element 311 that have lost their support instantly move away from the discharge pipe 213 through the control slot 313. The screen 311 is swung in the direction of the bottom until it collides with the left inner wall of the screening frame 310. At this time, the corn kernels on the right side of the screen 311 are vibrated by the collision, so that the damaged corn kernels pass through the screening slot 312 and move from the right side of the screen 311 to the left side of the screen 311, and contact the left inner wall of the screening frame 310. At this time, the waste slot 316 is covered by the bottom of the screen 311 until the active tooth 314 engages with the driven tooth 315 again, so that the active tooth 314 rotates and drives the driven tooth 315 to drive the screen 311 to move toward the bottom of the discharge pipe 213. The screen 311 is separated from the waste slot 316, and the damaged corn seeds screened out roll along the inner wall of the screening frame 310 toward the waste slot 316 to the waste pipe 318, and finally fall into the collection box 317.

The fertilizer seeder 1 is also fixedly provided with a drip irrigation barrel 216 , which is provided with a drainage hole. The nutrient solution in the drip irrigation barrel 216 flows to the farmland through the drainage hole, so that the corn absorbs the nutrients in the nutrient solution.

Working principle:

Step 1: When screening corn seeds, firstly, the fertilizer planter 1 is started by controlling the switch, so that the seed sorting disc 214 inside the seed sorter 212 rotates, and at the same time, the corn seeds in the hopper 211 are lowered into the screening frame 310 through the feeding pipe 213;

Step 2: The seed disc 214 rotates while driving the active gear 314 to rotate, and the active gear 314 drives the driven gear 315 to rotate, so that the driven gear 315 drives the screening element 311 to swing, and the corn seeds move in the screening frame 310 with the swinging screening element 311. When the active gear 314 is separated from the driven gear 315, the screening element 311 swings downward in the screening frame 310 through the control slot 313 until the screening element 311 hits the inner wall of the screening frame 310. At this time, the screening element 311 is moved downward in the screening frame 310. After the damaged corn kernels on one side of the screening frame 310 are impacted, they move from the screening slot 312 to the side of the screening member 311 close to the inner wall of the screening frame 310. As the seed sorting disc 214 continues to rotate, the active tooth 314 is meshed with the driven tooth 315 again, and drives the driven tooth 315 to rotate. At this time, the screening member 311 is also swung upward again, and the waste slot 316 blocked by the screening member 311 leaks out, so that the screened damaged corn kernels fall from the waste pipe 318 into the collection box 317.

Step 3: During sowing, as the seed disc 214 rotates, corn kernels are sucked into the seeding groove 215 one by one. At this time, the control disc 230 also rotates synchronously with the seed disc 214. While the control disc 230 rotates, the roller 233 drives the positioning rod 232 to move synchronously back and forth along the trajectory of the wave groove 231, and further the concave part 223 drives the push rod 222 on the push plate 221 to intermittently extend into the seeding groove 215, so that the push rod 222 pushes out the corn seeds in the seeding groove 215, and finally the pushed out corn seeds are buried in the soil along the planting tube;

Step 4: While the corn seeds are buried in the soil, the fertilizer planter 1 spreads fertilizer near the corn seeds, and at the same time, the water in the drip irrigation barrel 216 is irrigated onto the fertilizer and corn, so that the corn seeds can fully absorb the water and nutrients of the fertilizer.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
