[0001] This utility model relates to the field of grain cleaning technology, specifically to an environmentally friendly mobile grain cleaning screen. Background Technology

[0002] Grain cleaning screens are ideal equipment for cleaning and removing impurities from grains in large central reserves and during grain purchase and storage. They have high output, are equipped with advanced environmental protection dust removal equipment, and are easy to move.

[0003] However, existing grain cleaning screens have low practicality and are inconvenient for workers to bag because the discharge port of the screen does not have a material collection mechanism. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly mobile grain cleaning screen to solve the problem mentioned in the background art that it is inconvenient to bag grain when it is directly shaken out.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly mobile grain cleaning screen, comprising:

[0006] The cleaning screen body has a material collecting component installed on the outer wall of the discharge port of the cleaning screen body, and a limit component is provided below the cleaning screen body;

[0007] A material collection assembly includes a material collection hopper, with bolts penetrating the interior of both sides of the hopper. A cover plate abuts against the bottom of the hopper, and one side of the cover plate is connected to the hopper via a hinge. A rotating rod abuts against the lower surface of the cover plate, and a fixing rod penetrates the interior of one end of the rotating rod.

[0008] Preferably, the limiting component includes a support plate, a hydraulic cylinder is fixedly installed in the middle of the upper surface of the support plate, a toothed plate is fixedly connected to one end of the drive rod of the hydraulic cylinder, a guide block passes through the inside of the toothed plate, a guide wheel meshes with the lower outer wall of the toothed plate, a rotating plate is fixedly installed on both sides of the guide wheel, a shaft passes through the inside of the guide wheel and the rotating plate, and a fixing block is fixedly installed at both ends of the shaft.

[0009] Preferably, the bolt is threadedly connected to the main body of the cleaning screen, and the cover plate is rotatably connected to the hopper via a hinge.

[0010] Preferably, the rotating rod and the fixed rod are rotatably connected.

[0011] Preferably, the upper part of the fixing rod is fixedly connected to the hopper, and the support plate is fixedly connected to the main body of the cleaning screen.

[0012] Preferably, the toothed plate is slidably connected to the guide block, and the guide block is fixedly connected to the support plate.

[0013] Preferably, the guide wheel and the rotating plate are rotatably connected to the shaft, and the fixing block is fixedly connected to the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The mobile grain cleaning screen of this utility model, through the setting of the collection component, allows the grain coming out of the discharge port of the main body of the cleaning screen to fall into the collection hopper. The grain falling into the collection hopper is concentrated and discharged from the bottom of the collection hopper without shaking, which is convenient for bagging. When changing the bag, the cover plate can be rotated by the hinge and placed under the collection hopper. The rotating rod is rotated so that the rotating rod is pressed against the bottom of the cover plate to seal the grain in the collection hopper, which improves the practicality and makes it convenient for workers to directly bag the grain.

[0016] (2) With the setting of the limiting component, the main body of the mobile grain cleaning screen of this utility model inevitably moves slightly during operation. After the main body of the cleaning screen is stopped in a suitable position, the hydraulic cylinder is started. The drive rod of the hydraulic cylinder drives the toothed plate to move, the toothed plate drives the guide wheel to rotate, and the guide wheel drives the rotating plate to rotate around the shaft, so that the two rotating plates are pressed against the ground, which greatly increases the friction between the two plates and the ground and reduces the possibility of movement of the main body of the cleaning screen during operation.

A cover plate 23 abuts against the bottom of the material collection hopper 21. The cover plate 23 is rotated via a hinge 24 to cover the bottom of the material collection hopper 21. A rotating rod 25 is rotated so that it abuts against the bottom of the cover plate 23, sealing the grain inside the material collection hopper 21. One side of the cover plate 23 is connected to the material collection hopper 21 via a hinge 24. The lower surface of the cover plate 23 abuts against the rotating rod 25, which abuts against the bottom of the cover plate 23 to seal the grain inside the material collection hopper 21. A fixing rod 26 passes through the inside of one end of the rotating rod 25.

[0027] Furthermore, the limiting component 03 includes a support plate 31, which provides power. Activating the support plate 31 can drive its drive rod to move, thereby moving the toothed plate 33. A hydraulic cylinder 32 is fixedly installed in the middle of the upper surface of the support plate 31. One end of the drive rod of the hydraulic cylinder 32 is fixedly connected to the toothed plate 33. A guide block 34 passes through the inside of the toothed plate 33, which guides the toothed plate 33 and ensures the accuracy of the toothed plate 33's movement direction. A guide wheel 35 meshes with the lower outer wall of the toothed plate 33. Rotating plates 36 are fixedly installed on both sides of the guide wheel 35. The rotating plates 36 can rotate around the shaft 37. The rotating plates 36 press against the ground, greatly increasing the friction between them. The shaft 37 passes through the inside of the guide wheel 35 and the rotating plates 36. Fixing blocks 38 are fixedly installed at both ends of the shaft 37.

[0028] Furthermore, the bolt 22 is threadedly connected to the cleaning screen body 01.

The cover plate 23 is rotatably connected to the collection hopper 21 through the hinge 24. When the cover plate 23 is open, it does not affect the discharge of grain in the collection hopper 21. When the cover plate 23 is closed, it can seal the grain in the collection hopper 21.

[0029] Furthermore, the rotating rod 25 is rotatably connected to the fixed rod 26, and the cover plate 23 is rotated through the hinge 24 to cover the bottom of the collection hopper 21. The rotating rod 25 is rotated so that it abuts against the bottom of the cover plate 23 to seal the grain in the collection hopper 21.

[0030] Furthermore, the upper part of the fixing rod 26 is fixedly connected to the hopper 21 to ensure the stability of the fixing rod 26. The support plate 31 is fixedly connected to the cleaning screen body 01 to ensure the stability of the support plate 31. The support plate 31 provides power. Starting the support plate 31 can drive its drive rod to move, thereby driving the toothed plate 33 to move.

[0031] Furthermore, the toothed plate 33 is slidably connected to the guide block 34, the guide block 34 guides the toothed plate 33, and the guide block 34 is fixedly connected to the support plate 31 to ensure the stability of the position of the guide block 34. The guide block 34 guides the toothed plate 33 and ensures the accuracy of the moving direction of the toothed plate 33.

[0032] Furthermore, both the guide wheel 35 and the rotating plate 36 are rotatably connected to the shaft 37. The rotating plate 36 can rotate around the shaft 37. The rotating plate 36 rests against the ground, greatly increasing the friction between it and the ground. The fixing block 38 is fixedly connected to the support plate 31, ensuring the stability of the fixing block 38 and thus ensuring the stability of the shaft 37.

[0033] Working Principle: In use, first screw bolt 22 through the hole in the collection hopper 21 and into the cleaning screen body 01 to install the collection hopper 21. After stopping the cleaning screen body 01 in the appropriate position, start the hydraulic cylinder 32. The drive rod of the hydraulic cylinder 32 drives the toothed plate 33 to move, the toothed plate 33 drives the guide wheel 35 to rotate, and the guide wheel 35 drives the rotating plate 36 to rotate around the shaft 37, so that the two rotating plates 36 touch the ground. After starting the cleaning screen body 01, pour in the grain. The grain coming out of the discharge port of the cleaning screen body 01 will fall into the collection hopper 21. The grain falling into the collection hopper 21 is concentrated and discharged from below the collection hopper 21. Bags are then placed below the collection hopper 21. When changing the bags, the cover plate 23 can be rotated via the hinge 24 to cover the bottom of the collection hopper 21. Rotate the rotating rod 25 so that the rotating rod 25 touches the bottom of the cover plate 23, sealing the grain in the collection hopper 21. The above is the complete working principle of this utility model.
