[0016] Compared with the prior art, the present invention provides a wheat seed processing and screening device, which has the following beneficial effects:

[0017] This wheat seed processing and screening equipment, through its deceleration and anti-clogging device, starts when the equipment begins operation. The drive unit (including the drive gear, driven gear, mounting frame, and drive motor) is activated, driving the rotating shaft and auxiliary shaft to rotate. As the rotating shaft and auxiliary shaft rotate, multiple sets of deceleration rods and their flexible heads fixed on them begin to contact the material, gently and slowly pushing the wheat seeds forward. This ensures that the material is evenly distributed on the second screen. The design of the deceleration rods and flexible heads effectively disperses the material flow, reducing material accumulation on the screen and thus preventing clogging. By continuously pushing the material forward, it is possible to evenly distribute the material on the screen, improving screening efficiency and quality, and ensuring that all wheat seeds can be effectively screened.

[0023] 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.

[0024] Please see Figure 1-4A wheat seed processing and screening device includes a screening box 1, a first screen 2, a second screen 3, a deceleration and anti-clogging device, and a moving device. A feed inlet 4 is installed at the top of the screening box 1, and a feed hopper 5 is installed at the top of the feed inlet 4. The first screen 2 is installed at an incline in the upper part of the screening box 1. A first vibration motor 6 is installed at the higher end of the first screen 2, penetrating the side wall of the screening box 1. A waste discharge frame 7 is opened at the end of the screening box 1 away from the first vibration motor 6. A guide plate 8 is installed below the first screen 2, and a dust collection device is installed below the guide plate 8. The second screen 3, with an inclination direction opposite to that of the first screen 2, is installed below the dust collection device. One end of the second screen 3... A second vibration motor 9 is installed through the side wall of the screening box 1. A discharge port 10 is opened at the lower part of the side wall of the screening box 1 near the second screen 3. A deceleration and anti-clogging device is installed above the second screen 3. The deceleration and anti-clogging device includes a rotating shaft 11, an auxiliary shaft 12, a deceleration rod 13, a flexible head 14, and a driving device. The rotating shaft 11 is rotatably installed inside the screening box 1. Two sets of auxiliary shafts 12 are symmetrically installed inside the screening box 1 about the central axis of the rotating shaft 11. Multiple sets of deceleration rods 13 are installed in a ring on the side walls of both the main shaft and the auxiliary shafts 12. The flexible head 14 is installed at the output end of each deceleration rod 13. The driving device is installed on the front side wall of the screening box 1. The bottom wall of the screening box 1... Equipped with the aforementioned mobile device, in this embodiment, during use, wheat seeds are first placed into the feed hopper 5 and fed into the screening box 1 through the feed inlet 4. After entering the screening box 1, the wheat seeds first come into contact with the inclined first screen 2. The first screen 2 is driven by an externally connected first vibration motor 6 to vibrate, helping to separate larger impurities. These impurities are discharged through the impurity discharge frame 7 at one end of the screening box 1. The wheat seeds passing through the first screen 2 fall onto the guide plate 8 and then slide into the dust collection device area. The dust collection device removes lighter dust and other fine impurities. Next, the wheat seeds reach the second screen 3, which is inclined in the opposite direction to the first screen 2. The second screen 3 is also driven by an externally connected second vibration motor 9. This step further... The first screening step selects wheat seeds that meet the size requirements. Simultaneously, the drive unit is activated, causing the rotating shaft 11 and auxiliary shaft 12 to rotate. As the rotating shaft 11 and auxiliary shaft 12 rotate, multiple sets of reduction gears 13 fixed to them also begin to rotate. The reduction gears 13 and their flexible heads 14 contact the material, continuously and slowly pushing the material forward to ensure it is evenly distributed on the second screen 3. This ensures that all falling wheat seeds pass through the second screen 3, guaranteeing screening efficiency. Furthermore, the design of the flexible heads 14 prevents the reduction gears 13 from directly contacting the second screen 3. Finally, after two screenings and dust removal, the wheat seeds flow out from the discharge port 10 near the lower part of the second screen 3 on the side wall of the small screening box 1, ready for packaging or further processing.Smaller residues and substandard wheat pass through the second screen 3 and are collected at the bottom of the screening box 1.

[0025] In practical use, to further facilitate the rotation of the rotating shaft 11 and the auxiliary shaft 12, in this embodiment, the driving device includes a driving gear 15, a driven gear 16, a mounting frame 17, and a drive motor 18. One end of the rotating shaft 11 penetrates the side wall of the screening box 1 and is fitted with the driving gear 15. One end of the auxiliary shaft 12 penetrates the side wall of the screening box 1 and is fitted with the driven gear 16. The driving gear 15 and two sets of driven gears 16 are meshed together. The mounting frame 17 is installed on the outer wall of the driving gear 15 and the driven gear 16. The drive motor 18 is installed on the outer wall of the mounting frame 17. The output end of the drive motor 18 passes through the side wall of the mounting frame 17 and is connected to the rotating shaft 11. When the equipment is running, the drive motor 18 installed on the outer wall of the mounting frame 17 is started first. The output end of the drive motor 18 is directly connected to the rotating shaft 11. Therefore, after the drive motor 18 is started, it will drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the driving gear 15 on the outer wall to rotate. Through the meshing action between the gears, it can drive the two sets of driven gears 16 to rotate, realizing the rotation action of the rotating shaft 11 and the auxiliary shaft 12.

[0026] In practical use, further dust collection is achieved from the wheat. In this embodiment, the dust extraction device includes a dust collector 19, a collection box 20, dust extraction holes 21, and air inlet slots 22. The dust collector 19 is installed directly below the guide plate 8. Multiple sets of dust extraction holes 21 are provided at one end of the dust collector 19 near the lower part of the guide plate 8. The collection box 20 is installed at the other end of the dust collector 19 via a transmission pipe. Multiple sets of air inlet slots 22 are provided on the side wall of the screening box 1 corresponding to the dust extraction holes 21. When the screening equipment is running, the dust collector 19 is simultaneously activated to extract dust from the wheat. The dust collector 19 generates negative pressure through multiple sets of dust extraction holes 21 at one end. To enhance this negative pressure effect, multiple sets of air inlet slots 22 are provided on the side wall of the screening box 1 corresponding to the dust extraction holes 21. This helps to form an effective airflow path, allowing air to enter from the air inlet slots 22, pass through the area under the guide plate 8, and finally be drawn into the dust collector 19 by the dust extraction holes 21. During this process, lighter dust and other tiny impurities in the wheat seeds are carried away by the airflow and drawn into the dust collector 19 along with the airflow. These impurities are transported to the collection box 20 connected to the dust collector 19 through the transmission pipe.

[0027] In actual use, the collected residue is further discharged. In this embodiment, the bottom wall of the screening box 1 is equipped with a guide seat 23 with an inclined surface, and the lower side wall of the screening box 1 is provided with a slag discharge frame 24. During the screening process, smaller residues and unqualified wheat enter the bottom wall of the screening box 1 through the second screen 3. Due to gravity, when the residues are guided by the inclined guide seat 23 to the slag discharge frame 24 on the lower side wall of the screening box 1, they can be automatically discharged out of the screening box 1 through the slag discharge frame 24.

[0028] In practical use, to further facilitate the adjustment of the size of the feed inlet 4, in this embodiment, the side wall of the feed hopper 5 is provided with a sliding groove 25, and an adjusting plate 26 is slidably installed in the sliding groove 25. The adjusting plate 26 can be manually or with tools pushed to move back and forth along the sliding groove 25. When the adjusting plate 26 is moved outward, the feed inlet 4 becomes larger, and when the adjusting plate 26 is pushed inward, the feed inlet 4 becomes smaller. In this way, the opening size of the feed inlet 4 can be flexibly adjusted. By adjusting the size of the feed inlet 4, the amount of material entering the screening equipment can be precisely controlled according to the actual processing requirements, thereby improving work efficiency and processing capacity.

[0029] In practical use, to further facilitate the movement of the screening box 1, in this embodiment, the moving device includes casters 27. The casters 27 are installed at the four corners of the bottom of the screening box 1. The use of casters 27 greatly enhances the mobility of the screening equipment, allowing it to be quickly and easily adjusted according to production needs, and adapt to different working environments and layout requirements.

[0030] In practical use, to further facilitate the fixing of the screening box 1, in this embodiment, the universal wheel 27 is provided with a brake assembly 28. The brake assembly 28 is adapted to the universal wheel 27. When the screening box 1 is accurately placed in the required position, the operator needs to activate the brake assembly 28 on each universal wheel 27. The brake assembly 28 will lock the rotation and steering function of the universal wheel 27 to prevent the screening box 1 from sliding accidentally. When the screening box 1 is in working state, the fixed equipment is more stable, which helps to improve screening efficiency and accuracy.

[0031] In practical use, to further facilitate auxiliary support for the screening box 1, in this embodiment, a cylinder 29 is installed in the middle of the bottom wall of the screening box 1, and a support plate 30 is installed at the bottom output end of the cylinder 29. When auxiliary support for the screening box 1 is required, the cylinder 29 is activated, and the bottom output end of the cylinder 29 extends downward, driving the support plate 30 installed on it toward the ground. With the additional support provided by the support plate 30 driven by the cylinder 29, the screening box 1 becomes more stable, reducing slight movement caused by external vibration or the operation of the equipment itself, and improving the overall stability of the equipment.
