[0002] The cleaning screen is an ideal equipment for cleaning and removing impurities from grain in large central reserve warehouses and grain purchasing and storage. Its main function is to clean and remove impurities from grain feed processing and auxiliary materials. There may be residues on the screen frame after the cleaning screen has screened the grain. If it is not cleaned in time, it will affect the screening of the grain, so a cleaning screen that is easy to clean the screen surface is needed.
[0003] At present, a cleaning screen capable of automatically cleaning the screen surface is described in the patent with publication number CN212190072U, and its composition includes: a screening box, the top and bottom surfaces of which are both open structures, and a screen is embedded in the opening of the top surface of the screening box; side baffles are tightly welded near the left and right edges of the top surface of the screening box; the cleaning screen capable of automatically cleaning the screen surface is provided with a cleaning mechanism, that is, the piston rod of the cylinder is extended and retracted to drive the scraper to move horizontally on the screen, and during the horizontal movement, the scraper scrapes off the debris accumulated on the screen, and the screen pushes the debris to be discharged to the outside through the flap; this design changes the traditional way of using a cleaning brush to clean the screen surface of a cleaning screen.

The elasticity of the limiting spring 20 is used to push the insertion rod 18 to be inserted into the inside of the collecting box 12, which can conveniently fix the collecting box 12, and then the collecting box 12 can be used to conveniently collect the discharged impurities.
[0030] A screen 8 is arranged inside the bottom plate 4, a screening box 1 is arranged at the top of the bottom plate 4, and a vibration motor 16 is arranged on one side of the screening box 1. The operation of the vibration motor 16 can drive the screening box 1 and the bottom plate 4 to vibrate synchronously. At this time, under the action of vibration, small particles of the material fall through the screen 8, and large particles of debris accumulate on the screen 8; limit blocks 17 are arranged around the bottom plate 4, and a limit rod 6 is arranged for sliding inside the limit block 17. A buffer spring 5 is arranged on the outer sleeve of the limit rod 6. The buffer spring 5 can absorb the impact force generated when the device is working. A support rod 7 is arranged at the bottom end of the limit rod 6, which can conveniently support the bottom plate 4. A telescopic cylinder 3 is arranged at the end of the screening box 1 away from the fixed seat 9, and a push cylinder 3 is arranged at the output end of the telescopic cylinder 3. The piston rod of the movable plate 2 and the telescopic cylinder 3 drives the pushing plate 2 to move toward the side of the collecting box 12. At this time, the pushing plate 2 pushes the debris accumulated on the screen 8 to move toward the side of the collecting box 12, so that the debris is discharged from the bottom plate 4 into the inside of the collecting box 12, and the impurities discharged by the device can be collected. Both sides of the pushing plate 2 are slidably connected with guide rods 14, and the guide rods 14 are connected to the screening box 1; a mounting seat 15 is provided at one end of the screening box 1 close to the fixed seat 9, and the mounting seat 15 can provide bearing capacity. A baffle 13 is provided inside the mounting seat 15 to facilitate blocking the vibrating material and prevent the material from falling. The baffle 13 runs through the inside of the bottom plate 4, and a sealing gasket is provided on the outside below the baffle 13 to better block the material.
[0031] See also Figure 4A handle 11 is provided at one end of the collection box 12 away from the bottom plate 4, which is convenient for the staff to hold. A mounting groove 24 is opened inside the handle 11, and a magnet block 23 is provided inside the mounting groove 24. An anti-slip cover 21 is provided outside the handle 11, and metal sheets 22 are provided above and below the inner surface of the anti-slip cover 21. By utilizing the magnetic connection between the magnet block 23 inside the mounting groove 24 and the metal sheet 22, the anti-slip cover 21 can be installed on the outside of the handle 11, which can increase the friction force on the outside of the handle 11 and facilitate the staff to move the collection box 12.
[0032] Working principle: First, the user piles the material on the screen 8, then the user turns on the power of the vibration motor 16, and the vibration motor 16 starts to work, which can drive the screening box 1 and the bottom plate 4 to vibrate synchronously. At this time, under the action of vibration, small particles of the material fall through the screen 8, and large particles of debris accumulate on the screen 8;
[0033] Secondly, when it is necessary to clean the screen 8, the user first stops the vibration motor 16, places the collection box 12 on the fixing seat 9, and then uses the elasticity of the limit spring 20 to push the insertion rod 18 into the interior of the collection box 12, so that the collection box 12 can be easily fixed; then the baffle 13 is moved out from the bottom plate 4 and the mounting seat 15, and at the same time, the user controls the telescopic cylinder 3 to start working synchronously, and the piston rod of the telescopic cylinder 3 drives the push plate 2 to move toward one side of the collection box 12. At this time, the push plate 2 pushes the debris accumulated on the screen 8 to move toward the side of the collection box 12, so that the debris is discharged from the bottom plate 4 into the interior of the collection box 12, and the impurities discharged by the device can be collected, thereby effectively improving the practicality of the device;
[0034] Finally, by inserting the metal sheet 22 on the anti-slip sleeve 21 into the interior of the mounting groove 24, and utilizing the magnetic connection between the magnet block 23 inside the mounting groove 24 and the metal sheet 22, the anti-slip sleeve 21 can be installed on the outside of the handle 11, thereby increasing the friction force on the outside of the handle 11, making it easier for the staff to move the collection box 12, thereby facilitating the processing of impurities inside the collection box 12. After the impurities inside the collection box 12 are collected, the insertion rod 18 can be removed from the interior of the collection box 12 by pulling the movable rod 19, making it easier for the staff to hold the handle 11 and remove the collection box 12 for cleaning.
