[0002] Seed purification is a crucial step in ensuring wheat seed purity and improving agricultural production efficiency. By removing weeds, diseased plants, inferior plants, and various impurities, the following objectives can be achieved:

[0003] Ensuring seed purity: Preventing hybrid plants from competing with the main variety for nutrients, ensuring stable traits in offspring. Improving yield and quality: Reducing interference from weeds and impurities on wheat growth, increasing thousand-grain weight and marketability. Maintaining seed safety: Preventing mechanical mixing or human negligence from causing seed quality degradation, protecting farmers' income.

[0004] The existing methods for removing impurities from wheat seeds mostly involve manual sorting. Since wheat seeds are stored in piles, sorting requires turning the seeds over while picking out impurities, which is relatively inefficient. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a wheat seed impurity removal device, which solves the problem of having to turn the wheat seeds over and remove impurities while picking them.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wheat seed impurity removal device, comprising a fixed plate and a support frame, a box body fixedly connected to one side of the fixed plate, a support plate fixedly connected to the inner wall of the box body, a vertical cylinder fixedly connected to one end of the support plate, a discharge bin fixedly connected to the top of the vertical cylinder, a motor fixedly mounted on the upper surface of the discharge bin, a rotating shaft fixedly connected to the output end of the motor, a spiral conveyor plate fixedly connected to the surface of the rotating shaft, and a screw conveyor plate fixedly connected to the lower surface of the discharge bin. There is a second support plate, and a blower mechanism is fixedly connected to the bottom end of the second support plate. Both the first and second blower mechanisms include a blower and an air outlet chamber. The air outlet of the blower passes through the air outlet chamber and is fixedly connected to it. An inclined groove is rotatably installed inside the support frame. A baffle is fixedly connected to the bottom of the inclined groove. A third support plate is fixedly connected to one side of the inclined groove. An inclined groove is fixedly connected to the top of the third support plate. A baffle is inserted inside the inclined groove.

[0007] Preferably, the gap between the edge of the spiral conveyor plate and the vertical cylinder is 2mm.

[0008] Preferably, there are two sets of support plates, located between the first blower mechanism and the discharge bin, and between the second blower mechanism and the first blower mechanism, respectively.

[0009] Preferably, the second blower mechanism has one more pair of blowers than the first blower mechanism.

[0010] Preferably, a collection box is slidably mounted on the upper surface of the fixing plate.

[0011] Preferably, the height of the first blower mechanism is higher than the highest point of the second inclined groove, and the height of the second blower mechanism is higher than the highest point of the first inclined groove.

[0012] Preferably, a connecting seat is fixedly connected to the lower surface of the inclined groove, and a hydraulic telescopic rod is movably installed inside the support frame, with the top end of the hydraulic telescopic rod being movably connected to the connecting seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The wheat seed impurity removal device, through the setting of the spiral conveyor plate 8, mainly drives the rotating shaft through the output end of the motor to rotate, thereby conveying the wheat seeds in the box upward to the discharge bin. The blower mechanism one helps to blow out the lighter impurities contained in the wheat seeds, thereby separating them from the wheat seeds. The lighter impurities can fall into the inclined trough two for storage. Since the blower mechanism two has one more pair of blowers than the blower mechanism one, it can blow out a stronger airflow than the blower mechanism one, which helps to blow the wheat seeds onto the inclined trough one. The heavier impurities will fall into the collection box. The wheat seeds are located between the baffles in the inclined trough one. Since the inclined trough one is inclined, the wheat seeds can slide from high to low, which makes it easy to visually observe and pick out inferior seeds without having to turn the wheat seeds.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides the following technical solution: a wheat seed impurity removal device, including a fixed plate 1 and a support frame 12. A box 2 is fixedly connected to one side of the fixed plate 1. A support plate 3 is fixedly connected to the inner wall of the box 2. A vertical cylinder 4 is fixedly connected to one end of the support plate 3. A discharge bin 5 is fixedly connected to the top of the vertical cylinder 4. A motor 6 is fixedly installed on the upper surface of the discharge bin 5. A rotating shaft 7 is fixedly connected to the output end of the motor 6. A spiral conveying plate 8 is fixedly connected to the surface of the rotating shaft 7. A second support plate 9 is fixedly connected to the lower surface of the discharge bin 5. The bottom end of the second support plate 9 is fixedly... A blower mechanism 10 is fixedly connected to the bottom of a support plate 29, and a blower mechanism 21 is fixedly connected to the bottom of the support plate 29. Both blower mechanism 10 and blower mechanism 211 include a blower 101 and an air outlet chamber 102. The air outlet of the blower 101 passes through the air outlet chamber 102 and is fixedly connected to it. An inclined groove 13 is rotatably installed inside the support frame 12. A baffle 14 is fixedly connected to the bottom of the inclined groove 13. A support plate 35 is fixedly connected to one side of the inclined groove 13. An inclined groove 26 is fixedly connected to the top of the support plate 315. A baffle 17 is inserted into the inclined groove 216.

[0024] In this embodiment, the spiral conveyor plate 8 is mainly driven by the output end of the motor 6 to rotate the shaft 7, thereby conveying the wheat seeds in the box 2 upward to the discharge bin 5. The blower mechanism 10 helps to blow out the lighter impurities contained in the wheat seeds, thereby separating them from the wheat seeds. The lighter impurities can fall into the inclined trough 16 for storage. Since the blower 101 of the blower mechanism 11 has one more pair than the blower 101 of the blower mechanism 10, it can blow out a stronger airflow than the blower mechanism 10, which helps to blow the wheat seeds onto the inclined trough 13. The heavier impurities will fall into the collection box 18. The wheat seeds are located between the baffles 14 in the inclined trough 13. Since the inclined trough 13 is inclined, the wheat seeds can slide from high to low, which makes it easier to visually observe and pick out inferior seeds without having to turn the wheat seeds.

[0025] Specifically, the gap between the edge of the spiral conveyor plate 8 and the vertical cylinder 4 is 2mm, so as to avoid the vertical cylinder 4 affecting the rotation of the spiral conveyor plate 8, and the size of the wheat seed is larger than the gap, so the wheat seed will not get stuck.

[0026] Specifically, there are two sets of support plates 29, located between blower mechanism 10 and discharge bin 5, and between blower mechanism 21 and blower mechanism 10, respectively. The support plates 29 can be used to fix blower mechanism 10 and blower mechanism 21, respectively.

[0027] Specifically, the blower 101 of the second blower mechanism 11 has one more pair than the blower 101 of the first blower mechanism 10, so the second blower mechanism 11 can generate a stronger airflow than the first blower mechanism 10. This airflow is strong enough to change the falling path of the wheat seeds, which is beneficial to blowing the wheat seeds onto the inclined trough 13.

[0028] Specifically, a collection box 18 is slidably mounted on the upper surface of the fixing plate 1. The collection box 18 is designed to collect impurities that are heavier than wheat seeds.

[0029] Specifically, the height of the blower mechanism 10 is higher than the highest point of the inclined trough 2 16, so that the blower mechanism 10 can blow lighter impurities onto the inclined trough 2 16, and the height of the blower mechanism 2 11 is higher than the highest point of the inclined trough 13, so that the blower mechanism 2 11 can blow wheat seeds onto the inclined trough 13.

[0030] Specifically, a connecting seat 19 is fixedly connected to the lower surface of the inclined groove 13, and a hydraulic telescopic rod 20 is movably installed inside the support frame 12. The top end of the hydraulic telescopic rod 20 is movably connected to the connecting seat 19. The hydraulic telescopic rod 20 can adjust the angle of the inclined groove 13 by extending and retracting, thereby adjusting the sliding speed of the wheat seeds on the inclined groove 13.

[0031] The working principle or usage process of this utility model is as follows: When using this utility model, the wheat seeds that need impurity removal are first placed into the box 2. Then, the motor 6 is started to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the spiral conveyor plate 8 to rotate, which can transport the wheat seeds in the box 2 upwards to the discharge bin 5. Next, the blower mechanism 10 and the blower mechanism 21 are simultaneously activated. The wheat seeds can fall through the discharge bin 5. The blower mechanism 10 helps to blow out the lighter impurities contained in the wheat seeds, thus separating them from the wheat seeds. The lighter impurities can fall into the inclined trough 26 for storage. Since the blower mechanism 21 has one more pair of blowers 101 than the blower mechanism 101, it can blow out a stronger airflow than the blower mechanism 101. The system facilitates blowing wheat seeds onto the inclined trough 13, while heavier impurities fall into the collection box 18. The wheat seeds are positioned between the baffles 14 within the inclined trough 13. Because the inclined trough 13 is inclined, the wheat seeds can slide from high to low, making it easier to visually observe inferior seeds and manually remove them without turning them over. Controlling the extension and retraction of the hydraulic telescopic rod 20 allows for adjustment of the angle of the inclined trough 13, thereby adjusting the sliding speed of the wheat seeds on the inclined trough 13. A separate conveying device can be installed to receive and transport the wheat seeds after impurity removal. By removing the baffle 17, it is convenient to clean the impurities collected in the inclined trough 16. All electrical equipment in this system is externally powered and its operation and shutdown are controlled by a matching control switch.

[0032] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
