[0003] The above scheme solves several problems existing in the traditional manual sowing process, such as the uneven depth of drilling holes, the low germination rate caused by the mixing of wheat grain varieties, and the difficulty in achieving single-grain sowing. However, when the above scheme is applied to a soil environment with high humidity, the first roller and the second roller are easily adhered to wet and sticky soil. This adhesion not only increases the resistance of the user when pushing the seeder, making the pushing process more laborious, but also affects the stability of the seeder, making it prone to swaying and bumping during the pushing process. In order to solve this problem, cleaning is often required, but the main cleaning method at present is manual shoveling with a shovel, which is time-consuming and labor-intensive. Therefore, a wheat grain seeder is needed to solve the above technical problems. Utility Model Content

An adjusting falling speed plate 12 is slidably connected to the inside of the flat square tube 6, and a connecting strip plate 13 is fixedly connected to the side of the adjusting falling speed plate 12 away from the flat square tube 6. The inner thread of the connecting strip 13 is connected with a second screw rod 14 , one end of the second screw rod 14 away from the flat square tube 6 is fixedly connected with a second handle 15 , and one end of the second screw rod 14 away from the second handle 15 is rotatably connected to the flat square tube 6 .

[0022] The support frame 1 is provided with a scraper mechanism 5, which includes a mounting plate 501 fixedly connected to the support frame 1, and the mounting plate 501 is internally threaded with a first screw rod 502. The top of the first screw rod 502 is fixedly connected with a first handle 503, and the bottom of the first screw rod 502 is rotatably connected with a connecting square plate 504, and the upper surface of the connecting square plate 504 is in contact with the mounting plate 501. The upper surface of the connecting square plate 504 is fixedly connected with a sliding rod 508, and the sliding rod 508 is slidably connected with the inside of the mounting plate 501 and penetrates to the outside of the mounting plate 501. The bottom surface of the connecting square plate 504 is fixedly connected with a telescopic rod 506, and the bottom end of the telescopic rod 506 is fixedly connected with a scraper ring 507. The upper surface of the scraper ring 507 is fixedly connected with a spring 505, and the top of the spring 505 is fixedly connected with the connecting square plate 504.

[0023] The mud scraping mechanisms 5 are provided at two locations, one being provided above the first roller 2 and the other being provided above the second roller 3, in a symmetrical state.

[0024] The scraper mechanism 5 is provided to effectively remove the mud adhered to the first roller 2 and the second roller 3. Specifically, the scraper mechanism 5 includes a scraper ring knife 507, which can cling to the surface of the roller to scrape off the adhered mud, thereby keeping the roller clean. This not only reduces the resistance when the user pushes the seeder, making the pushing process easier, but also improves the stability of the seeder, reduces the swaying and bumping during the pushing process, and further improves the accuracy and efficiency of sowing.

[0025] By setting the adjusting falling speed plate 12 and the second screw rod 14, the user can conveniently control the falling speed of the seeds. Specifically, by rotating the second screw rod 14, the position of the adjusting falling speed plate 12 inside the flat square tube 6 can be adjusted, thereby changing the size of the channel through which the seeds pass and adjusting the falling speed. This design enables the seeder to adapt to different sowing needs and improves the flexibility and accuracy of sowing. At the same time, with the use of the discharge tip tube 9 and the adjusting screw 17, the sowing depth can also be conveniently adjusted, further enhancing the applicability and practicality of the seeder.

[0026] Working principle: First, the user pushes the seeder forward through the push handle 4, and the first roller 2 and the second roller 3 roll on the ground, driving the seeder to move as a whole. During the movement, the wheat seeds in the seeding box 7 fall into the discharge tip tube 9 through the flat square tube 6 and the discharge tube 8, and are then sown into the soil. In order to adapt to the soil with different humidity and the sowing depth requirements, the position of the discharge tip tube 9 can be adjusted by adjusting the screw 17. When the sowing depth needs to be adjusted, the adjusting screw 17 is rotated to make it slide on the discharge tube 8, thereby driving the discharge tip tube 9 to move up and down, so as to achieve the purpose of adjusting the sowing depth. At the same time, in order to control the falling speed of the seeds, the second screw rod 14 can be rotated to make the adjustment drop speed plate 12 move up and down inside the flat square tube 6. When the adjustment drop speed plate 12 moves upward When the seeder moves, the channel through which the seeds pass becomes narrower and the falling speed slows down; on the contrary, the falling speed speeds up. When more soil adheres to the first roller 2 and the second roller 3, at this time, by adjusting the distance between the scraper ring 507 and the rollers, the first screw rod 502 is rotated to make the connecting square plate 504 and the scraper ring 507 connected thereto move downward, so that the scraper ring 507 contacts the rollers, wherein, through the action of the telescopic rod 506 and the spring 505, it can be closely attached to the surface of the roller, and then by repeatedly pushing the seeder back and forth, the first roller 2 and the second roller 3 are driven to rotate, so that the scraper ring 507 can be used to scrape off the soil adhered to the first roller 2 and the second roller 3. In addition, the V-shaped backfill plate 11 backfills the soil into the sowing furrow during the movement of the seeder to complete the soil covering work after sowing.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
