[0002] With the development of agricultural mechanization, the traditional manual sowing method has been difficult to meet the requirements of modern agriculture for high efficiency, precision, and labor saving. As a small, lightweight, and flexible agricultural machinery and equipment, the push-type seeder has been widely used in agricultural production due to its advantages such as simple operation, high efficiency, and low cost.

[0003] In the existing push-type seeder, the seeds are placed in a rolling sowing box and will accumulate at the bottom due to the action of gravity, resulting in a blocking phenomenon, which will seriously affect the sowing effect. In addition, there are some push-type seeders that are provided with a power source for driving the discharge wheel to rotate, so that the mechanical vibration amplitude is relatively large during sowing, affecting sowing and increasing the weight of the whole machine. Summary of the Utility Model

[0016] In order to make the patent purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] In order to illustrate the technical solution described in the present utility model, the following is illustrated through specific embodiments.

[0018] For the sake of convenience of description, only parts related to the embodiments of the present utility model are shown.

[0019] Combined with Figures 1-4As shown in the figure, the push-type seeder includes a frame 1, on which there are two front and rear traveling wheels 2. A handle 3 is provided at the rear end of the frame 1. A seeding mechanism is provided on the frame 1 between the two traveling wheels. The seeding mechanism includes a base 4, an outlet bin 5 is formed inside the base 4, a seeding box 6 is provided on the base 4, the outlet of the seeding box 6 faces the outlet bin 5, a discharge wheel 7 is rotatably provided in the seeding box 6 at the outlet position, a number of shallow grooves 8 are formed along the circumferential direction on the discharge wheel 7, a plowshare 9 is provided at the bottom of the base 4, a soil covering frame 10 is provided at the rear end of the plowshare 9, the outlet of the outlet bin 5 is located inside the plowshare 9, and a transmission mechanism for driving the discharge wheel 7 to rotate is provided on the frame 1.

[0020] With the development of agricultural mechanization, the traditional manual seeding method has been difficult to meet the requirements of modern agriculture for high efficiency, precision, and labor saving. As a small, lightweight, and flexible agricultural machinery and equipment, the push-type seeder has been widely used in agricultural production due to its advantages such as simple operation, high efficiency, and low cost.

[0021] When using this seeder for seeding, first pour the seeds into the seeding box. The operator can then hold the handle and insert the front end of the plowshare into the soil for a short distance, and then push the handle to make the seeder move. During the movement of the seeder, first, the plowshare opens a planting groove. At the same time, under the drive of the transmission mechanism, the discharge wheel rotates. During the rotation of the discharge wheel, when the shallow groove faces down and rotates to the outlet of the seeding box, the seeds in the current shallow groove fall into the planting groove through the outlet bin, and finally, under the action of the soil covering frame, the soil on both sides of the planting groove is pushed back into the planting groove to cover the seeds in the planting groove.

[0022] In this structure, as Figure 4 , a discharge pipe 11 is connected to the bottom of the outlet bin 5. When the seeds are fed into the outlet bin through the discharge wheel, the seeds in the outlet bin are discharged into the planting groove through the discharge pipe. During the discharging process of the seeds, the discharge pipe plays a role of guiding the materials, enabling the seeds to accurately fall into the planting groove and improving the seeding effect.

[0023] In addition, a baffle 12 is provided on the inner side of the bottom of the seeding box 6 opposite to the discharge wheel 7. In this structure, the baffle plays a role of blocking the materials, preventing the seeds from directly flowing out through the gap between the seeding box and the discharge wheel. At the same time, during the rotation of the discharge wheel, the baffle can level the seeds in the shallow groove.

[0024] As a preferred structure, in combination with Figure 1 、 Figure 3, the transmission mechanism includes a driving gear 13 rotatably installed on the vehicle frame 1 and connected to the shaft rod of the front traveling wheel. A rotating shaft is rotatably provided on the base 4. Linkage gears 15 are provided on both sides of the rotating shaft. A transmission gear 16 is provided on the side wall of the base 4. Matching transmission chains 17 are sleeved between the driving gear 13, the transmission gear 16 and the linkage gears 15 on the same side. A driving gear 18 is provided on the side wall of the discharging wheel 7, and the driving gear 18 meshes with the transmission chain 17 on the same side.

[0025] When pushing this seeder to walk for seeding operation, under the action of the front traveling wheel, the driving gear rotates synchronously. Under the linkage of the corresponding transmission chain, the linkage gears rotate synchronously. At the same time, under the linkage of the other transmission chain, the driving gear rotates synchronously, thereby driving the discharging wheel to rotate, and thus completing the seeding action.

[0026] In this structure, only by means of the rotation of the front traveling wheel, which drives the two transmission chains to rotate, can the discharging wheel be driven to rotate for discharging. The overall design structure is relatively simple and the seeding effect is also good.

[0027] In addition, combined with Figures 1-2 , the handle 3 includes a pushing frame 31 rotatably installed on the vehicle frame. A support frame 32 is rotatably provided below the pushing frame 31. Long grooves 33 are opened on both sides of the support frame 32. A number of adjusting grooves 34 communicating with the long grooves 33 are evenly opened on the support frame. Fixing nuts (not shown in the figure) are inserted into two corresponding adjusting grooves 34 on both sides. The fixing nuts are screwed into the vehicle frame 1 to lock. Threaded holes 35 are opened on both sides at the rear end of the vehicle frame.

[0028] In this seeder, the height of the handle can be finely adjusted to adapt to staff of different heights, improving the comfort of the staff during the seeding operation. When adjusting the installation height of the handle, first unscrew the fixing nuts for locking the support frame, and then adjust the support frame up and down. For example, when adjusting the handle downwards by a small distance, move the support frame downwards until the next adjusting groove aligns with the threaded hole on the same side, and then insert the fixing nut into this adjusting groove until the fixing nut is screwed into the threaded hole. When both fixing nuts are screwed into the threaded holes on the same side as required, the adjustment of the handle is completed.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
