DETAILED DESCRIPTION

[0018] 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.

[0019] Example: Figures 1-5 As shown, this utility model provides an anti-clogging feeding mechanism for a wheat planter, including a feeding bin 1. A cylindrical frame 2 is fixedly connected to the bottom end of the discharge port of the feeding bin 1. A rotating roller 3 is rotatably connected inside the cylindrical frame 2. One end of the rotating shaft of the rotating roller 3 extends to one side of the cylindrical frame 2 and is fixedly connected to a turntable 5. A connecting rod 6 is rotatably connected to one side of the turntable 5. A fixing rod 7 is fixedly connected to the side of the cylindrical frame 2 near the turntable 5. A piston cylinder 8 is fixedly installed on the fixing rod 7. A piston plate 9 is slidably engaged inside the piston cylinder 8. A piston rod 10 is fixedly connected to the top end of the piston plate 9. The top end of the piston rod 10 is rotatably connected to the bottom end of the connecting rod 6. A connecting pipe 11 communicating with the inside of the piston cylinder 8 is fixedly connected to the bottom end of the piston cylinder 8. A connecting pipe 21 communicating with the inside of the connecting pipe 11 is fixedly connected to one side of the top of the connecting pipe 11. A one-way valve is provided inside both the connecting pipe 21 and the connecting pipe 11.

[0020] A through groove 13 is provided at the bottom end of the cylindrical frame 2. A feeding pipe 12 is fixedly connected to the bottom end of the cylindrical frame 2 and outside the through groove 13. An annular pipe 14 is fixedly connected to the bottom end of the feeding pipe 12. The bottom end of the connecting pipe 11 is fixedly connected to the annular pipe 14. Several vent holes 15 are provided on the inner wall of the bottom end of the feeding pipe 12. The vent holes 15 communicate with the interior of the annular pipe 14.

[0021] By adopting the above technical solution, when the transmission shaft 16 rotates, it drives the large gear 17 to rotate. The large gear 17 meshes with the small gear 18, which in turn drives the small gear 18 and the rotating roller 3 to rotate, thereby realizing the sowing and feeding operation. Furthermore, by utilizing the different diameters of the large gear 17 and the small gear 18, the transmission ratio between the large gear 17 and the small gear 18 is controlled, so that the rotating roller 3 reaches a suitable speed.

[0022] Mounting plates 19 are fixedly connected to both sides of the top of the loading hopper 1, and mounting holes 20 are opened on both sides of the top of the mounting plates 19.

[0023] By adopting the above technical solution, the installation and positioning of the loading bin 1 can be facilitated through the cooperation between the mounting plate 19 and the mounting hole 20.

[0024] The bottom of the inner wall of the loading hopper 1 is set in a conical shape.

[0025] By adopting the above technical solution, and by setting the bottom of the inner wall of the loading bin 1 to a conical surface, wheat seeds can slide more smoothly down the inner wall of the loading bin 1 under the action of gravity, reducing the resistance of the material during the feeding process and thus improving the flowability of the material.

[0026] The side of the rotating roller 3 has several receiving grooves 4 that are equidistantly and centrally symmetrically distributed.

[0027] By adopting the above technical solution and setting up the receiving trough 4, the wheat seeds fall into the receiving trough 4 and move with the rotation of the rotating roller 3. When the receiving trough 4 rotates to the position corresponding to the through trough 13, the seeds are finally discharged from the through trough 13 by gravity, thereby achieving uniform sowing.

[0028] Working principle: When using a wheat seeder to sow wheat seeds, the wheat seeds are loaded into the loading bin 1. When the drive shaft 16 rotates, it drives the large gear 17 to rotate. The large gear 17 meshes with the small gear 18, which in turn drives the small gear 18 and the rotating roller 3 to rotate. This causes the wheat seeds that fall into the receiving trough 4 to move with the rotation of the rotating roller 3. When the receiving trough 4 rotates to the position corresponding to the through trough 13, the seeds are discharged from the through trough 13 by gravity, thus achieving uniform sowing.

[0029] During the sowing process, the feed inlet of the wheat seeder is easily blocked by straw due to its large amount, coarseness, and disordered distribution. The rotation of the rotating roller 3 drives the turntable 5 to rotate, which in turn drives the top of the connecting rod 6 to rotate. The piston rod 10 guides the bottom of the connecting rod 6, while pushing the piston plate 9 to reciprocate along the inside of the piston cylinder 8. When the piston plate 9 moves upward, the one-way valve inside the connecting pipe 21 opens and the one-way valve inside the connecting pipe 11 closes, allowing air to enter the inside of the piston cylinder 8 from one end of the connecting pipe 21. When the piston plate 9 moves downward, the one-way valves inside the connecting pipe 21 and the connecting pipe 11 open, and the air inside the piston cylinder 8 is compressed and discharged from the connecting pipe 11 into the inside of the annular pipe 14, and finally ejected through the exhaust hole 15, clearing the blockage at the opening of the feed pipe 12.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
