[0036] The embodiment of the present utility model specifically provides a wheat impurity screening device. Please refer to Figure 1 , which includes a screening frame 1, a screening plate 2, a fixing component 3 and an elastic component 4.

[0037] Among them, a vibration motor 11 is fixedly installed on the outside of the screening frame 1. The vibration force of the vibration motor 11 drives the screening frame 1 to vibrate, realizing the vibration screening of wheat grains. The screening frame 1 is arranged above the base 12. The base 12 is used to be fixed with the placement surface. The upper surface of the base 12 is provided with an open structure, so that the screened wheat grains can all fall through the opening. The external wheat grain receiving component can be directly placed below the opening.

[0038] The screening plate 2 is arranged at intervals above the opening. One end of the screening plate 2 is rotatably installed on the screening frame 1, and the other end is detachably fixed to the screening frame 1 through the fixing component 3, so that waste can be quickly discharged from the screening plate 2. The elastic component 4 is arranged on the screening frame 1 and the base 12, and provides vibration buffering for the screening frame 1 through the elastic component 4.

[0039] Further, please refer to Figure 1 And Figure 2, an elastic washer 13 is fixedly installed on the bottom side of the screening frame 1. The material of the elastic washer 13 can be silica gel or rubber, which has relatively excellent elastic properties. The screening plate 2 includes a plate body 21, a screen mesh 22, and a mounting plate 23. The top side of the plate body 21 is in contact with the elastic washer 13 to improve the fitting effect between the plate body 21 and the screening frame 1, and to facilitate the subsequent rotation of the plate body 21, avoiding jamming between the plate body 21 and the screening frame 1. A screening opening is provided in the middle of the plate body 21, and the screen mesh 22 is fixedly installed in the screening opening. The wheat grains are screened and dropped below the open end through the screen mesh 22, while the waste rods and stones with larger particles remain on the screen mesh 22. The outer side of the mounting plate 23 is fixedly connected to the screening frame 1, and the left and right ends of the plate body 21 are rotatably connected to the mounting plate 23, enabling the plate body 21 to rotate on the mounting plate 23. When it is necessary to discharge and clean the waste on the filter screen 22, the filter screen 22 can be directly rotated to keep it inclined, facilitating the direct discharge of the waste.

[0040] Specifically, please refer to Figure 3 , a lengthening plate 24 is fixedly installed on the side of the plate body 21 close to the fixing component 3. The fixing component 3 includes a driving component 31, a rotating rod 32, a support plate 33, and a locking component 34. The driving component 31 is fixedly installed on the rotating rod 32, the outer side of the rotating rod 32 is rotatably connected to the support plate 33, the support plate 33 is fixedly connected to the outer side of the screening frame 1, and the rotating rod 32 is connected to the lengthening plate 24 through the locking component 34. When the screen mesh 22 is in daily use, the lengthening plate 24 drives the plate body 21 to be fixed to the screening frame 1 under the action of the locking component 34.

[0041] Among them, the driving component 31 includes a driving part and a driven part that mesh with each other. The driven part is driven by the driving part, and the driven part is installed on the rotating rod 32. When the rotating rod 32 rotates, it can drive the locking component 34 to lock or unlock, facilitating the rotational fixation or separation of the plate body 21 and the screening frame 1.

[0042] Furthermore, please refer to Figure 4 , the driving part includes a worm 311, a mounting cylinder 312, and a rotating handle 313.

[0044] Specifically, please refer to Figure 5, the latch assembly 34 includes a bracket 341, a plug rod 342, a locking block 343 and a locking groove 344. The top of the bracket 341 is fixed to the rotating rod 32, and the outside of the plug rod 342 is fixed to the bracket 341. When the rotating rod 32 rotates, the plug rod 342 can be driven to move through the bracket 341. The locking block 343 is fixedly installed on the outside of the extension plate 24, the locking groove 344 is opened in the locking block 343, and the plug rod 342 is in sliding contact with the inner wall of the locking groove 344. Through the connection and cooperation of the plug rod 342 and the locking groove 344, the plate body 21 can be fixed to the screening frame 1, facilitating the screening of wheat grains.

[0045] Among them, the plug rod 342 is driven by the bracket 341 to displace in a circular trajectory. The overall shape of the locking groove 344 is an arc structure that matches the displacement trajectory of the plug rod 342, and the top of the locking groove 344 is an open structure. The inner wall of the locking groove 344 is in sliding contact with the plug rod 342. When the plug rod 342 moves to the bottom of the locking groove 344, the inner wall of the locking groove 344 can apply vertical direction limitation to the plug rod 342, and at the same time, the locking groove 344 cannot move, thus fixing the plate body 21. When the plug rod 342 needs to be removed, only need to rotate the rotating rod 32 to move the plug rod 342 out of the locking groove 344.

[0046] Further, please refer to Figure 1 and Figure 3 , the elastic force assembly 4 includes a support rod 41, a first spring 42 and a support assembly 43.

During implementation, the outside of the support rod 41 is slidably arranged on the support 411, the support 411 is fixed to the outside of the base 12, and a spring seat 412 is fixedly installed at the bottom of the support rod 41. The upper and lower ends of the first spring 42 are respectively fixed to the support 411 and the spring seat 412. When the screening frame 1 vibrates up and down, the support rod 41 can slide on the support 411 to drive the screening frame 1 to displace up and down. At the same time, the first spring 42 provides elastic force for helping to reset and vibration buffering.

[0047] Among them, the support assembly 43 is arranged on the support rod 41. After the plate body 21 rotates and separates on the screening frame 1, the support assembly 43 can support and fix the inclined plate body 21 to facilitate the discharge of waste on the plate body 21.

[0048] During implementation, a convex plate 25 is fixedly arranged on the bottom side of the plate body 21, and a pin hole 26 is formed in the convex plate 25. The support assembly 43 includes a slide rod 431, a pull block 432 and a second spring 433. The outer side of the slide rod 431 is slidably connected to the support rod 41. The pull block 432 is fixedly installed at the outer end of the slide rod 431. The pull block 432 and the support rod 41 are connected by the second spring 433. The inner and outer ends of the second spring 433 are respectively fixed to the support rod 41 and the pull block 432. When the plate body 21 moves downward, the pull block 432 can be pulled outward by the pulling force, so that the inner end of the support rod 41 moves outward, and the plate body 21 continues to move downward. Then, after the support rod 41 is reset by the second spring 433, its inner end is inserted into the pin hole 26, so that the plate body 21 can be inclined and fixed. Through the action of the vibration motor 11, the inclined screen 22 can be driven to vibrate, and the impurities can be quickly cleaned and dropped out.
