[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figs. 1-3 In this embodiment of the utility model, a traction corn planting device includes a bracket 1, a traction rod 2 rotatably connected to the end of the bracket 1, a traveling wheel 4 rotatably connected to the inner side of the bracket 1, a material box 3 installed at the top of the bracket 1, and a feeding mechanism 5 set on the bracket 1, the traveling wheel 4, and the material box 3.

[0031] The feeding mechanism 5 includes a transmission unit and an anti-blocking unit;

[0032] The transmission unit is used to provide power for the uniform feeding of seeds;

[0033] The anti-clogging unit is used to prevent material from clogging inside the hopper 3;

[0034] The transmission unit includes a first shaft 501, a transmission rod 502, a second shaft 503, and a feed roller 504;

[0035] The first shaft 501 is fixed to the outer wall of the shaft of the traveling wheel 4 and extends to the inner side of the bracket 1. The first shaft 501 is used to synchronously drive one end of the transmission rod 502 to rotate circumferentially.

[0036] The transmission rod 502 is eccentrically rotatably connected to the outer wall of the first shaft 501, and the transmission rod 502 is used to synchronously drive the second shaft 503 to rotate.

[0037] The second shaft 503 is fixed to the outer wall of the shaft of the feed roller 504 and located inside the bracket 1. The second shaft 503 is used to synchronously drive the feed roller 504 to rotate.

[0038] The feeding roller 504 is rotatably mounted on the inner side of the bracket 1 and extends to the inner side of the feeding port of the material box 3. The feeding roller 504 is used to provide guidance for the uniform feeding of seeds inside the material box 3.

[0039] The anti-clogging unit includes a stop block 505, a movable rod 506, a positioning rod 507, and a spring 508;

[0040] The abutment 505 is fixed to the outer wall of the second shaft 503. The abutment 505 is used to intermittently provide a thrust to the movable rod 506 to move upward.

[0041] The movable rod 506 is vertically slidably installed on the inner wall of the material box 3 and extends to the outside of the bottom end of the material box 3. The movable rod 506 is used to provide friction for the material inside the material box 3.

[0042] The positioning rod 507 is fixed inside the material box 3 and passes through the protruding part of the outer wall of the movable rod 506. The positioning rod 507 is used to provide guidance for the vertical movement of the movable rod 506.

[0043] The two ends of the spring 508 are respectively engaged with the inner wall of the material box 3 and the protruding part of the outer wall of the movable rod 506. The spring 508 is used to always give the movable rod 506 a downward squeezing force.

[0044] In this embodiment: by connecting the traction rod 2 to a uniformly moving mechanical connection, the mechanical pull causes the bracket 1, traction rod 2, and material box 3 to move. Simultaneously, the traveling wheel 4 rotates, which in turn drives the first shaft 501, fixed to the outer wall of the shaft, to rotate. This causes one end of the transmission rod 502, eccentrically connected to the outer wall of the first shaft 501, to move circumferentially. The other end of the transmission rod 502, eccentrically connected to the second shaft 503, also rotates synchronously. The rotating second shaft 503 then synchronously drives the feeding roller 504 to rotate, causing the feeding slot on the feeding roller 504 to move from the inside of the material box 3 outwards. The feeding slot containing the seeds will then discharge the seed. As roller 504 rotates and falls, the seeds are evenly sown. During the rotation of the second shaft 503, the abutment block 505 also rotates with the second shaft 503. The rotating abutment block 505 will exert a squeezing force on the bottom of the movable rod 506 to move upward. The movable rod 506, which moves upward under the force, will move along the outer wall of the positioning rod 507 and exert a squeezing force on the spring 508. When the abutment block 505 is no longer in contact with the movable rod 506, the movable rod 506 will reset under the action of the spring 508. The moving movable rod 506 will contact the material inside the material box 3, giving the material friction to drive the material to move, avoiding material accumulation and blockage, and ensuring material feeding efficiency.

[0045] Please refer to this carefully. Figs. 1-3 The rotation trajectory of the abutment block 505 coincides with the position of the bottom of the movable rod 506. The outer wall of the bottom of the movable rod 506 is arc-shaped. The outer wall of the movable rod 506 protrudes and matches the outer wall of the positioning rod 507. The inside of the material box 3 is formed with a groove for the vertical movement of the protruding part of the outer wall of the movable rod 506. The outer wall of the feeding roller 504 is formed with a feeding slot. The feeding slots are evenly distributed in a ring on the outer wall of the feeding roller 504. The two ends of the transmission rod 502 are eccentrically rotatably connected to the outer walls of the second shaft 503 and the first shaft 501, respectively. The two ends of the transmission rod 502 are equidistant from the axis of the second shaft 503 and the first shaft 501.

[0046] In this embodiment: through this structure, during the mechanical traction movement of the walking wheel 4, the rotational force from the walking wheel 4 can be transmitted to the feeding roller 504, so that the feeding roller 504 rotates with the rotation of the walking wheel 4, thereby uniformly feeding the seeds inside the material box 3. The movable rod 506 at the arc-shaped bottom can convert the squeezing force of the abutment block 505 into the upward thrust of the movable rod 506 when it contacts the abutment block 505.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
