Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Embodiment 1:

1-7 , this embodiment discloses a cutting mechanism of a potato planter, including a feeding pipe 1 , a potato pressing assembly and a potato block adsorption assembly 8 , and two vertically arranged cutting knives 16 are installed at the bottom of the inner cavity of the feeding pipe 1 .

The potato block adsorption assembly 8 includes a sliding rod 810, a negative pressure pump 808, a fixing frame 811 fixed on the feed pipe 1, and a support ring 809 near the bottom end of the feed pipe 1. The sliding rod 810 is installed on the fixing frame 811, and an elastic member 812 is installed between the sliding rod 810 and the fixing frame 811. One end of the sliding rod 810 is fixedly connected to the support ring 809, and four potato block positioning assemblies are installed on the support ring 809. The negative pressure pump 808 is electrically connected to an external press control switch group, and the elastic member 812 is a spring, an elastic rod or an elastic air bag.

The potato block positioning assembly includes a support rod 805, one end of the support rod 805 is connected to the inner ring of the support ring 809 through a spring shock absorber 807, the spring shock absorber 807 is arranged along the radial direction of the feed pipe 1, the other end of the support rod 805 extends into the inner cavity of the feed pipe 1, and the end of the support rod 805 extending into the feed pipe 1 is installed with a suction nozzle 801, the suction nozzle 801 and the negative pressure pump 808 are connected through an air pipe 802, and a guide bracket 806 is fixed to the outer side of the support rod 805 near the inner wall of the feed pipe 1.

When no potato pieces are sucked onto the suction nozzle 801, the elastic member 812 drives the suction nozzle 801 to move toward the deep inner cavity of the feed pipe 1 through the sliding rod 810, the support ring 809, the spring shock absorber 807, and the support rod 805, and the suction nozzle 801 approaches the cutting knife 16. During the movement of the suction nozzle 801 toward the deep inner cavity of the feed pipe 1, the suction nozzle 801 approaches the central axis of the feed pipe 1 under the guidance of the guide bracket 806, and the guide bracket 806 and the support rod 805 keep the spring shock absorber 807 in an extended state.

Among them, potatoes are continuously added into the feeding pipe 1, and the potato pressing assembly pushes the potatoes toward the cutting knife 16. The suction nozzle 801 of each potato block positioning assembly absorbs potatoes, and the potatoes are divided into four potato blocks by the cutting knife 16. A potato block is absorbed on the suction nozzle 801 of each potato block positioning assembly, and the potato blocks are driven away from each other during the downward movement of the potato block positioning assembly.

Furthermore, the negative pressure pump 808 used in the present invention is a commonly used electronic component in the prior art, and its working method and circuit structure are well-known technologies and are not elaborated here. The spring shock absorber 807 is a commonly used part in the prior art, including a spring and a telescopic rod. The length of the spring shock absorber becomes shorter when squeezed by an external force, and the length of the spring shock absorber is restored after the external force is cancelled. The length of the spring shock absorber becomes longer when stretched by an external force, and the length of the spring shock absorber is restored after the external force is cancelled.

The working process and principle of this embodiment are:

The cutting mechanism of the potato planter is installed on an external material box, in which potatoes are placed, and the ratio of the diameter of the potatoes to the inner diameter of the feeding pipe 1 is 1.0:1.03-1.30.

The potato feeding mechanism is manually or externally moved to the feeding pipe 1, and the potato pressing assembly pushes the potato toward the cutting knife 16. The negative pressure pump 808 is controlled by the external pressing control switch group. When the cutting knife 16 is cutting the potato, the suction nozzle 801 of each potato block positioning assembly absorbs the cut potato, and the potato is divided into four potato blocks by the cutting knife 16. The suction nozzle 801 of each potato block positioning assembly absorbs the potato block, and the potato block is sucked by the suction nozzle 801 of each potato block positioning assembly. The weight of the block causes the support ring 809 to move downward and the elastic member 812 to undergo elastic deformation. The guide bracket 806 moves downward, shortening the elongation length of the length component of the spring shock absorber 807. During the downward movement of the potato block positioning component, the potato blocks are driven away from each other, thereby achieving separation of the potato blocks. The worker controls the negative pressure pump 808 to stop working through an external press control switch group, and the potato block and its corresponding suction nozzle 801 are separated. The potato block is manually caught and then thrown into the trench of the field soil.

The potato pressing assembly continuously pushes the potatoes toward the cutting knife 16 to achieve potato cutting and sowing, thereby preventing the cut surfaces of the potato pieces from sticking together and ensuring the uniformity of potato piece sowing.

Furthermore, the feeding pipe 1 is made of transparent plastic or transparent glass, which makes it easy to observe the cutting status of potatoes in the feeding pipe 1, and the elastic member 812 with different elastic coefficients can be replaced to adapt to potatoes of different weights.

Furthermore, the potatoes entering the feeding pipe 1 are preferably round or nearly round.

Embodiment 2:

As shown in Figures 1-3, this embodiment discloses a cutting mechanism of a potato planter, and its structure is roughly the same as that of the first embodiment, except that the potato pressing assembly of this embodiment includes two supporting shafts 9, which are symmetrically arranged at the bottom of the outer peripheral side of the feed pipe 1, and the supporting shafts 9 are rotatably installed on the feed pipe 1 through bearings. The length direction of the supporting shafts 9 is perpendicular to the length of the feed pipe 1, and fixed gears 6 are coaxially installed on the two supporting shafts 9. The two fixed gears 6 are meshed and the gear ratio of the two fixed gears 6 is 1:1. A number of pressure rods 10 are installed on the supporting shafts 9, and an opening 11 is opened on the outer peripheral side of the feed pipe 1 for the pressure rods 10 to pass through during the rotation process. A reduction motor 13 for driving one of the supporting shafts 9 to rotate is installed on the feed pipe 1, and the reduction motor 13 is electrically connected to an external press control switch group.

When the support shaft 9 drives the pressure rod 10 to rotate, the pressure rod 10 enters the inner cavity of the material conveying pipe 1 from the upper part of the opening 11 and leaves the inner cavity of the material conveying pipe 1 from the lower part of the opening 11 .

The working process and principle of this embodiment are:

The reduction motor 13 drives the supporting shaft 9 connected thereto to rotate, and the supporting shaft 9 drives another supporting shaft 9 to rotate synchronously through two fixed gears 6. The meshing position of the two fixed gears 6 rotates downward, and the pressure rods 10 on the two supporting shafts 9 synchronously enter the feeding pipe 1 through the opening 11. The rotating pressure rods 10 squeeze the potatoes so that the potatoes are cut by the cutting knife 16, and the potato pressing assembly works continuously to achieve continuous cutting of the potatoes.

A coaxial second bevel gear 7 is fixed on one of the fixed gears 6, and a rotating first bevel gear 5 is installed on the feed pipe 1. The first bevel gear 5 and the second bevel gear 7 are meshed, and the gear ratio of the first bevel gear 5 and the second bevel gear 7 is 1:1. The first bevel gear 5 and the rotating rod 3 are connected through a transmission shaft 4, and the first bevel gear 5 and the rotating rod 3 are connected to the end of the transmission shaft 4 through a universal joint.

The working process and principle of this embodiment are:

The fixed gear 6 drives the rotating rod 3 and the spiral blade 2 to rotate through the second bevel gear 7, the first bevel gear 5 and the transmission shaft 4. The spiral blade 2 causes the potatoes in the feeding pipe 1 to fall onto the cutting knife 16 at intervals, which facilitates the downward pressing and cutting of the potatoes by the potato pressing assembly and reduces the influence of potato stacking on the rotation of the pressing rod 10.

Embodiment 4:

As shown in Figure 7, this embodiment discloses a cutting mechanism of a potato planter, and its structure is roughly the same as that of the third embodiment. The difference is that the cutting knife 16 of this embodiment is provided with a receiving groove, and an electric heating device 17 is provided in the receiving groove. The electric heating device 17 is electrically connected to an external press-controlled switch group. The electric heating device 17 is an electric heating wire or an electric heating plate, and the electric heating device 17 heats the cutting knife 16.

The working process and principle of this embodiment are:

The spiral blades 2 that rotate synchronously with the supporting shaft 9 cause a time interval when the potatoes in the feeding pipe 1 fall on the cutting knife 16. During the time interval between when the cutting knife 16 has completed cutting one potato and when another potato has not fallen on the cutting knife 16, the electric heating device 17 generates heat on the cutting knife 16 to heat and sterilize the cutting knife 16, thereby reducing the risk of pathogens being transmitted between different potatoes through the cut surface.

Furthermore, when the cutting knife 16 cuts the potatoes, the cutting knife 16 heats the cut surface of the potato pieces, thereby reducing the water content of the cut surface of the potato pieces and reducing the risk of the cut surface of the potato pieces becoming moldy.

Embodiment five:

As shown in Figures 2 and 3, this embodiment discloses a cutting mechanism of a potato planter. On the basis of Example 2, Example 3 or Example 4, a solenoid valve 804 is installed on the air pipe 802 of this embodiment, four detection blocks 12 are installed at equal angles on one fixed gear 6, and the distance between each detection block 12 and the rotating axis of the fixed gear 6 is not equal, a support frame 15 is installed on the feed pipe 1, and a press control switch 14 is installed on the support frame 15 corresponding to each detection block 12, and each press control switch 14 is connected in series with a solenoid valve 804 and is electrically connected to an external press control switch group.

The solenoid valve 804 includes but is not limited to a direct-acting solenoid valve.

The push control switch 14 and the solenoid valve 804 used in the present invention are common electronic components in the prior art, and their working methods and circuit structures are well-known technologies and will not be described in detail here.

The working process and principle of this embodiment are:

When the detection block 12 does not contact the corresponding push control switch 14, the solenoid valve 804 is in an open state. The cutting mechanism of the potato planter realizes the automatic sowing of potato blocks at intervals, saves manpower, and reduces sowing costs.

Furthermore, affected by the shape of the potato surface, each suction nozzle 801 in the potato piece positioning assembly cannot be sucked on the potato surface, so that the air pressure in the inner cavity of the air pipe 802 close to the potato piece can be quickly restored after the solenoid valve 804 is closed.

Embodiment seven:

The deformation component 803 is elastic rubber, an air bag or a spring. The deformation component 803 allows the suction nozzle 801 to swing within a certain range after the suction nozzle 801 and the potato are adsorbed, thereby increasing the stability of the suction of the suction nozzle 801 and the potato.

Embodiment eight:
