[0002] A fertilizer seeder refers to a planting machine that uses crop seeds as the sowing object and adds a fertilization function. It is a fertilizer seeder used for a certain type or crop, and is often named after the crop type, such as grain strip fertilizer seeder, corn fertilizer seeder, cotton fertilizer seeder and forage fertilizer seeder. With the development of my country's agriculture, fertilizer seeders are also being used more and more.

This patent changes the pressure between the driving wheel and the ground by adjusting the adjustment component b. In the process of the driving device driving the driving ground wheel to rotate, the device as a whole has better dynamic performance and ensures the sowing quality. However, since the adjustment component b includes multiple threaded rods and compression springs, when adjusting multiple symmetrically arranged driving wheels, it is necessary to adjust each group of threaded rods one by one to complete the clamping operation of the driving wheel. This operation process is relatively cumbersome and has too many operation steps, which reduces work efficiency. At the same time, when each group of driving wheels is adjusted manually through multiple groups of adjustment components b, there may be different control strokes of each group of adjustment components b, resulting in different pressures of each group of driving wheels on the ground. When encountering complex and uneven terrain, the seeder body may tilt, thereby reducing the survival rate of seeds and affecting the sowing effect and quality of seeds. For this reason, a multifunctional fertilization seeder is proposed to solve the above problems. Utility Model Content

[0035] Working principle: When in use, the traction frame 5 of the seeder body 1 is installed and connected to the external traction vehicle. The external traction vehicle pulls and drives the seeder body 1 to move forward relative to the ground. When the seeder body 1 moves forward, it drives the sowing furrow opener 18 under the sowing mechanism to move forward. The ground is broken by the V-shaped tip on the front side of the sowing furrow opener 18, which makes it convenient for the seeder 17 on the rear side to sow seeds underground, thereby improving the survival rate of the seeds. After sowing, the ground is flattened by the covering wheel 23 to ensure that the seeds are covered with soil, thereby ensuring the survival rate of the seeds.

[0036] Facing different terrains, when the ground is uneven, the bulges on the ground squeeze the covering wheel 23, so that the covering wheel 23 drives the wheel fork 22 to move upward, thereby causing the movable block 21 to move upward relative to the fixed block 20, and through the transmission of the first connecting block 24 and the second connecting block 25, the slider 26 overcomes the elastic force of the spring 28 and moves upward. The reaction force of the spring 28 presses the covering wheel 23 against the ground, thereby improving the efficiency and quality of soil covering and ensuring the survival rate of seeds. By setting a positioning rod 29, multiple first connecting blocks 24 are fixed in series, so that when the seeder body 1 encounters uneven ground, multiple covering wheels 23 can maintain the same frequency of vibration and lifting, avoiding the different lifting amplitudes of the multiple covering wheels 23 causing the seeder body 1 to tilt when moving forward, reducing the influence of complex terrain on the operation of the seeder body 1 and improving the sowing quality.

[0037] By rotating the handwheel 10, the rotation of the handwheel 10 drives the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the control rod 12 to move downward. The movement of the control rod 12 drives the sleeve 13 to overcome the elastic force of the spring 14 and move downward, so that the compression amplitude of the spring 14 increases, thereby increasing the elastic force applied by the spring 14 to the support wheel 7, increasing the pressure of the support wheel 7 on the ground, increasing the grip of the support wheel 7, and improving the stability of the seed drill body 1 during the forward movement.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
