[0022] Example 1
[0023] Please refer to Figure 1-6 As shown, this utility model provides a wheat seed dressing device for agricultural planting, including a support frame 1, on which a seed dressing box 2 is fixedly connected; the bottom of the seed dressing box 2 is provided with a stirring assembly, which includes a transmission rod 3, on which a spiral blade 4 is fixedly connected to circulate and stir the material at the bottom of the seed dressing box 2; multiple stirring rods 5 are fixedly connected to the transmission rod 3, which are evenly distributed on the transmission rod 3 to ensure that the wheat seeds and the agent are fully contacted and stirred; a first motor 6 is fixedly connected to one end of the spiral rod to drive the transmission rod 3; and a scraper 7 is fixedly connected to the bottom of the transmission rod 3 to quickly discharge the seed-dressed wheat from the discharge port.
[0024] Specifically, the top of the seed mixing box 2 is fixedly connected to a liquid storage tank 8 for storing the ratio of water and pesticide. The bottom of the liquid storage tank 8 is fixedly connected to a liquid outlet pipe 9. One end of the liquid outlet pipe 9 is fixedly connected to a spraying disc 10. The bottom of the spraying disc 10 is fixedly connected to multiple nozzles 11. The multiple nozzles 11 are evenly distributed on the spraying disc 10, which can spray the wheat evenly.
[0025] The seed mixing box 2 is fixedly connected to a foreign object screening mechanism, which includes a grain pump 12 and a grain conveying pipe 13. The grain pump 12 is fixedly connected to a grain conveying pipe 13, which can continuously feed the screened wheat into the seed mixing box 2. One end of the grain conveying pipe 13 is fixedly connected to a screening box 14. The top of the screening box 14 is provided with a feed inlet 27. The inside of the screening box 14 is provided with a screen 15. The screen 15 is located below the feed inlet 27 and is tilted at a certain angle. The tilt angle of the screen 15 is 12-30°, preferably 18°.
[0026] Based on the above embodiments, specifically, a drive shaft 16 is fixedly connected to the bottom of the screen 15, and a rocker arm 28 is fixedly connected to the drive shaft 16 for connecting to the output end of the crank 17. One end of the rocker arm 28 of the drive shaft 16 is fixedly connected to the crank 17, causing the screen 15 to reciprocate. A second motor is provided on one side of the screening box, and the output end of the second motor cooperates with the crank for driving the screen 15. Support plates 19 are fixedly connected to both sides of the screen 15, and crank rods 20 are fixedly connected to the support plates 19. One end of the crank rods 20 is fixedly connected to the inner wall of the screening box 14, suspending the screen 15 inside the screening box 14. A waste collection box 26 is fixedly connected to one end of the screen, and the screened foreign objects enter the waste collection box 26 for centralized collection along the tilt of the screen.
[0027] Specifically, the seed mixing box 2 is equipped with two guide plates 21 inside to ensure that the wheat seeds slide smoothly into the seed mixing box 2 along the guide plates 21. Baffles 22 are fixedly connected to both sides of the guide plates 21. A heating ring 23 is provided in the wall of the seed mixing box 2 to accelerate the drying speed of the wheat seeds and the agent. A discharge pipe 24 is provided on one side of the bottom of the seed mixing box 2. A baffle valve 25 is provided on the discharge pipe 24 to control the discharge speed of the wheat seeds.
[0028] Working principle: First, wheat seeds enter the screening box 14 through the feed inlet 27. Driven by the second motor 18, the output end of the motor drives the crank 17 to rotate reciprocally. A rocker arm 28 is fixedly connected to one side of the crank 17, and a drive shaft 16 is connected to one end of the rocker arm 28, driving the screen 15 to move along the track. The support plates 19 on both sides of the screen 15 are connected by the crank 20, so that the screen 15 is suspended inside the screening box 14. Under the shaking of the screen 15, foreign objects in the wheat are separated and collected in the waste collection box through the waste outlet. The screened wheat seeds will pass through the screen 15, fall and accumulate in the screening box. At the bottom of the screening box 14; simultaneously, under the operation of the grain pump 12, the wheat seeds piled up at the bottom of the screening box 14 are sent to the inlet of the seed mixing box 2 through the grain conveying pipe 13. The wheat seeds slide smoothly into the seed mixing box 2 along the guide plate 21. When the wheat seeds slide past the guide plate 21, the spray plate at the top of the seed mixing box 2 sprays the agent onto the wheat seeds on the guide plate 21. Finally, when the wheat seeds slide into the bottom of the seed mixing box 2, the first motor 6 drives the stirring rod 5 on the transmission rod 3 to stir the wheat seeds and the agent, so that the agent and the wheat seeds are in uniform contact. The transmission rod 3 is equipped with a spiral blade 4, which stirs the wheat seeds repeatedly to improve the uniformity and quality of seed mixing.
[0029] The mixing box 2 is equipped with a heating ring 23 inside its wall. When the wheat seeds are mixed with the agent, the mixing area of the mixing box 2 is heated so that the surface of the wheat seeds can quickly combine with the agent and dry. The bottom side of the mixing box 2 is equipped with a discharge port, and a baffle valve 25 is installed on the discharge port. The wheat seeds after being mixed with the agent flow out of the equipment through the discharge port.
