[0002] With the rapid development of modern agriculture, seeders are being used more and more widely, and their stability and precision are crucial to improving crop yield and quality.

[0003] During the sowing process, the seeder needs to move forward at a constant speed along the preset route and accurately sow the seeds into the soil. However, in actual applications, due to the complex and changeable terrain of farmland and the widespread uneven ground, the seeder shakes due to the uneven ground during movement, causing the distance between the seeder and the soil to change, thereby affecting the depth and uniformity of sowing. In addition, the shaking may also cause dislocation or damage to the internal mechanism of the seeder, reducing its service life and reliability. Utility Model Content

[0004] The utility model aims to provide a feeding assembly for a continuous seeder, and the technical problem to be solved is to improve the stability of the seeder when it moves.

[0008] From the front end to the rear end of the above-mentioned mobile bracket, the following are arranged in sequence on the mobile bracket:

[0009] A soil-breaking member, the soil-breaking member extends out of a movable bracket; the soil-breaking member is used to break the soil and carve a groove in the soil;

[0010] A feeding pipe, the feeding pipe is connected to the feeding bin, the feeding pipe and the soil-breaking member are projected onto the orthographic projection of the movable bracket, and the connecting line of the orthographic projection of the feeding pipe and the orthographic projection of the soil-breaking member is parallel to the moving direction of the movable bracket; the feeding pipe is used to throw seeds into the broken groove;

[0011] A soil cover member, the soil cover member is used to gather soil in the trench;

[0012] A roller assembly, wherein the axial direction of the roller assembly is perpendicular to the moving direction of the movable bracket, and the roller assembly is used for flattening the gathered soil.

[0013] The pull rod is located at the front end of the mobile bracket, providing a stable traction point for the seeder; the mobile wheel is located at the rear end of the mobile bracket, providing stable support and mobility for the seeder;

[0014] The above-mentioned soil-breaking piece enables the seeder to break the soil first when moving forward, providing a stable soil environment for subsequent sowing work; the extended design of the soil-breaking piece ensures its contact area with the soil, improves the soil-breaking efficiency, and reduces the shaking of the seeder caused by uneven soil breaking; the positive projection connection line between the feed pipe and the soil-breaking piece is parallel to the moving direction, ensuring that the seeds can accurately fall into the grooves cut by the soil-breaking piece; the soil-covering piece gathers the soil in the sown grooves, providing a good foundation for the subsequent roller assembly to flatten the soil; it not only helps to fix the seeds, but also reduces the deterioration of the working environment of the seeder caused by soil scattering, thereby affecting its stability; the roller assembly flattens the soil, ensuring its uniformity and stability when flattening the soil. The flattening effect of the roller assembly not only helps the growth of seeds, but also further enhances the stability of the seeder when moving, avoiding vibrations caused by uneven soil.

[0015] Furthermore, the above-mentioned earth-breaking member includes a first connecting rod, a shovel and an earth-retaining plate;

[0016] The two ends of the first connecting rod are respectively connected to the shovel and the movable bracket;

[0017] The first connecting rod is connected to a retaining plate at one side close to the shovel; the retaining plate is used to disperse the broken soil to both sides of the groove.

[0018] The first connecting rod firmly connects the shovel with the mobile bracket, ensuring the stability of the shovel during the soil breaking process; avoiding the shaking or deviation of the shovel due to uneven force when breaking the soil, thereby improving the overall stability of the seed drill; the shovel is the main working part of the soil breaking part, responsible for breaking the soil and digging the trench;

[0019] The main function of the retaining plate is to disperse the broken soil to both sides of the trench, avoiding the soil from accumulating directly in the trench, reducing the problem of being unable to place seeds due to soil accumulation; through the action of the retaining plate, the shape of the trench can be better maintained, facilitating subsequent seed placement and soil burial work; the stable trench shape reduces the shaking of the seeder caused by soil changes during operation.

[0020] In summary, the coordinated work of the first connecting rod, shovel, retaining plate and other components in the soil-breaking part not only improves the soil-breaking efficiency, but also further improves the stability of the seeder when moving by optimizing soil distribution and reducing forward resistance. It helps to ensure the uniformity and accuracy of sowing, while reducing the impact of mechanical vibration on the sowing effect.

[0021] Furthermore, the feed pipe is connected to the first connecting rod.

[0022] Ensuring that the position of the feed tube is relatively fixed and will not shift due to the movement of the seeder helps to more accurately control the seed placement position.

[0023] Furthermore, the first connecting rod is provided with a guide groove, which is arranged along the length direction of the first connecting rod;

[0024] The feed pipe is connected with the guide groove.

[0025] On the one hand, the guide groove provides a fixed moving path for the seeds discharged from the discharge pipe, which solves the problem of seed deviation or throwing out due to vibration or external force, ensures that the seeds can be continuously and stably delivered from the discharge bin through the discharge pipe to the groove, and avoids uneven delivery or interruption caused by changes in the position of the discharge pipe.

[0026] On the other hand, the bottom of the feed pipe is prevented from being blocked when the feed pipe comes into close contact with the soil, thereby affecting the placement of seeds; the bottom of the guide groove is spaced a distance from the bottom of the first connecting rod to prevent the soil from blocking the bottom of the guide groove.

[0027] Furthermore, the soil covering member comprises a second connecting rod and a fixed plate, and two ends of the second connecting rod are respectively connected to the fixed plate and the movable bracket;

[0028] The fixing plate is provided with a first side plate and a second side plate, and the first side plate and the second side plate are symmetrical with respect to the mid-vertical plane of the fixing plate;

[0029] A first gathering cavity is formed between the first side plate and the second side plate;

[0030] From the front end portion to the rear end portion of the movable bracket, the radial cross-sectional area of ​​the first gathering cavity gradually decreases.

[0031] The design of the first side plate and the second side plate enables the soil to be effectively gathered in the first gathering cavity after being cut by the soil-breaking member. This gathering effect helps to reduce the scattering of soil during the movement of the seeder, thereby maintaining a clean working environment of the seeder and reducing the movement resistance caused by soil accumulation; the design of the first gathering cavity gradually reducing the radial cross-sectional area from the front end to the rear end enables the soil to be gradually compressed during the gathering process, further improving the compactness and stability of soil gathering;

[0032] By effectively gathering the soil, the soil covering piece reduces the direct contact between the soil and other parts of the planter, helps to reduce the friction and resistance of the soil on the moving parts of the planter, thereby improving the stability of the planter when moving.

[0033] The design of the soil covering piece also makes the operation of the seeder more continuous and stable, reducing the interruption or adjustment of sowing caused by improper soil preparation, thereby improving the sowing efficiency.

[0034] Furthermore, a third side plate and a fourth side plate are also provided on the fixing plate, the third side plate is connected to the first side plate, and the fourth side plate is connected to the second side plate;

[0038] The second gathering cavity further compresses the volume of the soil, improves the compactness and stability of soil gathering, helps to better fix the seeds in the soil, and reduces seed displacement or exposure caused by loose soil.

[0039] Furthermore, a discharge port is provided at the bottom of the lower material bin, and the lower material bin is connected to the lower material pipe through the discharge port;

[0040] The above-mentioned discharge port is provided with a material passing component;

[0041] The above-mentioned material transfer assembly includes a third connecting rod, a first material transfer plate and a second material transfer plate;

[0042] The first feeding plate and the second feeding plate are both provided with a central hole and a feeding hole, the first feeding plate and the second feeding plate are overlapped, and the third connecting rod passes through the central holes of the first feeding plate and the second feeding plate;

[0043] The first feeding plate and the second feeding plate are rotated around the third connecting rod to adjust the overlapping area of ​​the feeding holes on the first feeding plate and the second feeding plate.

[0044] The first feeding plate and the second feeding plate are both provided with feeding holes. By adjusting the overlapping area of ​​the feeding holes on the two feeding plates, the seed flow rate from the feeding bin into the feeding pipe can be flexibly controlled. This design enables the seeder to adapt to different sowing requirements, such as different sowing densities or sowing speeds, thereby improving the accuracy and efficiency of sowing.

[0045] Furthermore, the first feeding plate is connected to the lower feeding bin;

[0046] The lower material bin is provided with a strip-shaped opening, and the second material transfer plate is provided with a handle, which passes through the strip-shaped opening and extends out of the lower material bin; the handle moves in the strip-shaped opening.
