[0025] like Figures 1 to 5 As shown, the present invention includes a bracket 1, a connecting plate 2, a support column 3, a limiting cylinder 4, and a limiting rod 5. The bracket 1 is fixedly connected to both sides of the connecting plate 2. The support column 3 is fixedly connected to both sides of the top right side of the connecting plate 2.

The surface of the rubber pad 66 is covered with a sponge 8, and a dustproof cloth 9 is fixedly connected to the surface of the sponge 8.

[0027] As a technical optimization of this utility model, by setting up shock-absorbing grooves 7, sponge 8 and dustproof cloth 9, the multiple annularly distributed shock-absorbing grooves 7 on the front side of the rubber pad 66 can further enhance the absorption capacity of vibration. Combined with the sponge 8 covering the surface, the vibration can be further buffered by the deformation of the sponge 8. The dustproof cloth 9 on the surface of the sponge 8 can prevent dust, dirt and other contaminants from contaminating the sponge 8, extend the service life of the sponge 8, thereby continuously maintaining a good shock absorption effect and improving the grip experience of the operator.

[0028] refer to Figure 4 The top of the inner wall of the support 1 is fixedly connected to the feeding bin 10, and the bottom of the inner wall of the feeding bin 10 is movably connected to the seeding rod 11. The surface of the seeding rod 11 is provided with a feeding hole 12, and the bottom of the left side of the feeding bin 10 is provided with a through hole 13.

[0029] As a technical optimization of this utility model, by setting up a feeding bin 10, a sowing rod 11, a feeding hole 12, and a through hole 13, the feeding bin 10 at the top of the inner wall of the support 1 can store small-particle legume forage seeds. The sowing rod 11, which is movably connected, and the feeding hole 12 opened on its surface can make the seeds fall in an orderly manner. The through hole 13 at the bottom left side of the feeding bin 10 provides a channel for the seeds to fall, ensuring that the seeds can smoothly enter the sowing rod 11 from the feeding bin 10, realizing continuous and stable sowing of seeds, and helping to improve the uniformity of sowing.

[0030] refer to Figure 5 A fixing bracket 14 is fixedly connected to the inner wall of the through hole 13, and a brush plate 15 is fixedly connected to the top of the fixing bracket 14 by screws.

[0031] As a technical optimization of this utility model, by setting a fixing frame 14 and a brush plate 15, the brush plate 15 connected to the fixing frame 14 on the inner wall of the through hole 13 by screws can clean the surface of the sowing rod 11 during rotation, so as to avoid seed residue or impurities adhering to the sowing rod 11 and clogging the feeding hole 12, ensuring the smooth flow of the feeding hole 12, ensuring that the seeds can fall normally, reducing the phenomenon of missed sowing caused by blockage, and improving sowing efficiency.

[0032] refer to Figure 2 The bottom of the movable shaft 64 is movably connected to the top of the limiting rod 5. A baffle 16 is fixedly connected to the bottom of the limiting rod 5. A shock-absorbing spring 17 is fixedly connected to both the top and bottom of the baffle 16. The other end of the shock-absorbing spring 17 is fixedly connected to the inner wall of the limiting cylinder 4.

[0033] As a technical optimization of this utility model, by setting baffle 16 and shock-absorbing spring 17, the movable shaft 64 is movably connected to the top of the limiting rod 5, and the shock-absorbing spring 17 above and below the baffle 16 at the bottom of the limiting rod 5 is fixed to the inner wall of the limiting cylinder 4. When the seeder vibrates, the shock-absorbing spring 17 can further absorb and buffer the vibration through extension and contraction. Combined with the movement of the limiting rod 5, the overall structure's shock absorption effect is enhanced, further reducing the impact of vibration on the operator and improving the comfort of operation.

[0034] refer to Figure 4 A seeding plow 18 is fixedly connected to the right side of the inner wall of the support 1, and positioning wheels 19 are movably connected to both sides of the right side of the support 1. A covering plow 20 is fixedly connected to the bottom of the inner wall of the support 1.

[0035] As a technical optimization of this utility model, by setting up a seeding plow 18, a positioning wheel 19 and a covering plow 20, the seeding plow 18 on the right side of the inner wall of the support 1 can turn over the soil of the planting area, which is convenient for seed sowing.

[0036] The positioning wheels 19 on both sides can play a positioning role during the sowing process, ensuring the straightness and consistency of sowing;

[0037] The bottom covering plow 20 can cover the seeds with soil after sowing, ensuring that the seeds are covered by soil, providing a suitable environment for seed germination and improving the germination rate.

[0038] refer to Figure 4 The bottom of the feeding hopper 10 is fixedly connected to a guide plate 21, and the top of the guide plate 21 is provided with a guide hole 22.

[0039] As a technical optimization of this utility model, by setting a guide plate 21 and a guide hole 22, the guide plate 21 at the bottom of the feeding bin 10 and the guide hole 22 at the top can guide the seeds falling from the feeding bin 10, so that the seeds fall accurately into the feeding hole 12 of the sowing rod 11, avoid the seeds from scattering, ensure the accuracy of the seeds falling, and help improve the uniformity of sowing and the utilization rate of seeds.

[0040] refer to Figure 1 A soil-pressing wheel 23 is movably connected to the left side of the inner wall of the support 1, and scraper blades 24 are fixedly connected to both sides of the right side and the left side of the support 1.

[0041] As a technical optimization of this utility model, by setting up a soil compaction wheel 23 and a mud scraper 24, the soil compaction wheel 23 on the left side of the inner wall of the support 1 can compact the soil after the seeds are sown and covered with soil, so that the seeds are in close contact with the soil, which is conducive to the seeds absorbing water and nutrients.

[0042] The scraper blades 24 on both sides and the left side of the support 1 can scrape off the soil attached to the surface of the soil pressing wheel 23 and the positioning wheel 19 when they rotate, so as to avoid soil accumulation affecting the normal rotation of the wheels and ensure the stable operation of the seeder.

[0043] The working principle and usage process of this utility model are as follows: When in use, small-particle legume forage seeds are first poured into the feeding hopper 10. The operator holds the push rod 65 to move the device. During the movement, the vibration generated by the device is transmitted to the limiting rod 5 through the first movable shaft 61, the inclined rod 62, the sliding sleeve 63, and the second movable shaft 64. The limiting rod 5 moves within the limiting cylinder 4, and the shock-absorbing springs 17 above and below its bottom baffle 16 absorb part of the vibration through their extension and contraction.

[0044] Meanwhile, the rubber pad 66 on the surface of the push rod 65 and the shock-absorbing groove 7 further buffer the vibration, the sponge 8 enhances the shock absorption effect through its own deformation, and reduces the transmission of vibration to the operator's hands, while the dustproof cloth 9 protects the sponge 8.

[0045] As the device moves, the positioning wheel 19 and the compaction wheel 23 rotate synchronously, with the positioning wheel 19 ensuring that the device moves stably along a straight line.

[0046] The sowing plow 18 on the right side of the inner wall of the support 1 turns over the soil of the planting area to prepare for sowing. The seeds in the feeding bin 10 are sown through the sowing rod 11 at the bottom. When the sowing rod 11 rotates, the feeding hole 12 on its surface is connected to the bottom of the feeding bin 10 in sequence. The seeds fall through the feeding hole 12 and the through hole 13 at the bottom left side of the feeding bin 10. The brush plate 15 on the fixed frame 14 at the through hole 13 cleans its surface during the rotation of the sowing rod 11 to prevent impurities from clogging the feeding hole 12.

[0047] The guide plate 21 and guide hole 22 at the bottom of the feeding bin 10 guide the seeds to fall precisely into the turned soil;

[0048] After the seeds are sown, the soil covering plow 20 at the bottom of the inner wall of the support 1 covers the seeds with soil. Finally, the soil covering is compacted by the soil pressing wheel 23 to ensure that the seeds are in close contact with the soil, thus completing the entire sowing process.

[0049] In summary, this small-particle legume forage hand-held seeder, through the inclusion of a handle shock-absorbing mechanism 6, and the cooperation of movable shaft 1 61, inclined rod 62, sliding sleeve 63, movable shaft 2 64, and limiting rod 5, can buffer the vibration generated during the movement of the seeder. Combined with the rubber pad 66 covering the surface of the push rod 65, it can effectively reduce the transmission of vibration to the operator's hand, reduce hand fatigue, and allow the operator to hold and push the seeder more easily, improving the comfort and stability of operation, thereby ensuring the continuity and efficiency of the sowing operation.
