Description

Automatic fertilizer spreader for agricultural planting

Technical Field

The utility model relates to the technical field of agricultural planting, in particular to an automatic fertilizer spreader for agricultural planting.

Background technique

At present, in agricultural planting, fertilizers are often needed to improve soil and promote the growth of plants. As a compound that helps plant growth, fertilizers have always been an important factor in increasing crop yields. There are many varieties of fertilizers. According to the characteristics and nutritional components of fertilizers to provide plant nutrients, they are mainly divided into three categories: inorganic fertilizers, organic fertilizers, and organic-inorganic fertilizers. Whether it is inorganic fertilizers or organic fertilizers, they need to be scattered and applied in the fields when used. When fertilizing some crops, several different types of fertilizers need to be mixed and applied.

After searching, Chinese patent CN 214102312U in the prior art discloses an automatic fertilizer spreader for agricultural planting, including a base, a push rod, a charging box and a universal wheel, the left and right sides of the top of the base are fixedly connected with push rods, the top of the base is provided with a shaking device, the left and right sides of the top of the base are fixedly connected with one end of a first spring, the other ends of two groups of the first springs are fixedly connected with a screen plate, and the bottom of the base is provided with an adjusting device. The utility model uses hands to pour fertilizer into the charging box, and then rotates the output end of the first motor to drive the semicircular block to rotate. The rotation of the semicircular block causes the screen plate to shake up and down, and at the same time, the fertilizer flowing from the charging box to the top of the screen plate is shaken away, and the fertilizer is then evenly spread on the ridge blocks from the discharge trough, avoiding the fertilizer from being generally evenly spread on the ridge blocks when flowing out of the charging box, and at the same time avoiding some crops from not being able to grow well, thereby improving the practicality of the device.

However, the utility model automatic spreader can only spread seeds on the surface of the land each time, and the seeds will be exposed on the outside and cannot grow and develop, thereby producing more diseased and dead seedlings, and cannot meet production needs. Therefore, an automatic fertilizer spreader for agricultural planting is proposed to solve the above problems.

Compared with the prior art, the utility model provides an automatic fertilizer spreader for agricultural planting, which has the following beneficial effects:

1. The automatic fertilizer spreader for agricultural planting uses pear knives to spread the ground to both sides and separate the seeds. Then the seeds are evenly discharged from the first row of hoppers to the ground. As the push progresses, the parabolic stirring plate is used again to mix the land on the rear side with the seeds and cover them inside the ground, thereby improving the survival rate of the seeds.

2. The automatic fertilizer spreader for agricultural planting drives the first bevel gear on the outside of the rotating shaft to mesh with the second bevel gear through the first drive motor to drive the threaded rod to drive the threaded sleeve to move linearly downward or upward, thereby adjusting the height during sowing. This solves the problem that each time the seeds are scattered, they can only be sown on the surface of the land, and the seeds will be exposed on the outside and cannot grow and develop, thus resulting in more diseased and dead seedlings.

Embodiment 2:

Please refer to Figures 1-2. On the basis of Example 1, an adjustment component is fixedly installed on the right side of the base 1, and the adjustment component includes a first drive motor 7. The output end of the first drive motor 7 is fixedly connected to a rotating shaft 16. Two first bevel gears 17 are fixedly sleeved on the outer side of the rotating shaft 16. The surfaces of the two first bevel gears 17 are meshingly connected with second bevel gears 18. A threaded rod 9 is fixedly sleeved on the inner wall of the lower side of the second bevel gear 18. A threaded sleeve 10 is threadedly connected to the outer wall of the lower side of the threaded rod 9. A roller 11 is rollingly connected to the lower side of the threaded sleeve 10. Two telescopic support rods 8 are fixedly connected to the surface of the threaded sleeve 10. The rotating shaft 16 passes through the base 1 and extends to the inside thereof. The two first bevel gears 17 are fixedly sleeved on the surface of the rotating shaft 16 in a left-right relative structure. The two telescopic support rods 8 are fixed on the left and right ends of the threaded sleeve 10 in a left-right symmetrical structure.
