Description

Technical Field

[0001] The utility model relates to the technical field of cleaning screens, in particular to a cleaning screen which can automatically clean a screen surface. Background Art

[0002] The cleaning screen is an advanced cleaning and impurity removal device. It has a wide range of applications and good sealing performance. It uses adjustable spiral angle beating plates and cleaning brushes to clean materials with different impurity contents. The segmented screen drum and double-sided large door structure make operation and maintenance simple and quick.

[0003] According to a publicly disclosed cleaning screen that can automatically clean the screen surface (Announcement No.: CN220387159U), the cleaning brush arranged at the bottom end of the front bar in the above application cleans some impurities on the top of the screen, and the stones on the top of the screen are pushed by the front bar to move. Some stones roll down from the guide groove as the front bar moves, and the other part of the stones are stuck in the sieve holes of the screen. As the receiving frame moves, the roller is rotated through the sliding rod and the mounting rod, and the insertion rod is inserted into the sieve holes of the screen, exerting force to push out the impurities stuck in the sieve holes, and the impurities fall into the inside of the receiving frame for centralized processing.

[0004] However, in actual use, the above-mentioned equipment cannot clean impurities in a unidirectional manner. When the drum is reset, some impurities will be pushed to the opposite direction, making it difficult for the impurities to fall into the receiving frame below, thereby reducing the cleaning effect. In view of this, we propose a cleaning screen that can automatically clean the screen surface. Utility Model Content

[0010] Preferably, an ejection assembly is provided at the lower end of the vibration motor, and the ejection assembly includes a rotating motor. The lower end of the vibration motor is fixedly connected to the rotating motor, and the output end of the rotating motor is fixedly connected to a rotating shaft. The inner wall of the rotating shaft is rotatably connected to a cleaning wheel, and the cleaning wheel rotates to clean the mesh opening of the filter.

[0011] Preferably, a telescopic block is provided at the lower end of the slider, the inclined groove is opened on the telescopic block, the limit block is fixedly connected to the telescopic block, and the size of the inclined groove matches the size of the inclined top block, the size of the limit block matches the size of the trapezoidal groove, and the limit block is slidably connected to the inner wall of the trapezoidal groove, so that when the slider moves to the inclined end of the trapezoidal groove, the telescopic block extends to cause the cleaning plate to descend.

[0012] Preferably, the bottom area of ​​the conical block is larger than the area of ​​the end of the vibration motor close to the filter, and a folding plate matching the conical block is provided at the center of the cleaning plate, so that the cleaning plate can clean all areas on the upper end of the filter except the conical block.

[0015] Compared with the prior art, the present invention provides a cleaning screen that can automatically clean the screen surface, which has the following beneficial effects:

[0016] 1. The cleaning screen that can automatically clean the screen surface uses the trapezoidal groove and the limit block. When the slide moves to the inclined end of the trapezoidal groove, the inclined top block slides in the inclined groove, causing the lower end of the slide to descend, so that the cleaning plate contacts the filter screen for cleaning, and the limit block also moves to the lower end of the trapezoidal groove. When the slide moves to the vertical end, the telescopic block retracts and contracts, so that the cleaning plate leaves the filter screen, and the limit block moves to the upper end of the trapezoidal groove. When the cleaning plate reciprocates, it will only push out impurities from one direction, so that the impurities can better fall into the storage box, thereby improving cleaning efficiency.

[0017] 2. The cleaning screen that can automatically clean the screen surface drives the rotating shaft to rotate by rotating the motor, so that the cleaning wheel rotates on the filter screen. The soft rod on the cleaning wheel can push out the impurities in the mesh mouth, making it convenient for the cleaning plate to clean. At the same time, the spring on the rotating shaft can also clean the filter screen when it vibrates, pushing out the impurities in the mesh mouth to prevent the impurities from clogging the outlet and making it difficult for food to fall.

[0026] In one embodiment of the present invention, a cleaning plate 812 is fixedly connected to the outer wall of the slider 84 , a telescopic plate 813 is fixedly connected to the axis of the cleaning plate 812 , and push blocks 814 are fixedly connected to both ends of the cleaning plate 812 .

[0027] In addition, an ejection assembly 9 is provided at the lower end of the vibration motor 5, and the ejection assembly 9 includes a rotating motor 91. The lower end of the vibration motor 5 is fixedly connected to the rotating motor 91, and the output end of the rotating motor 91 is fixedly connected to the rotating shaft 92. The inner wall of the rotating shaft 92 is rotatably connected to the cleaning wheel 93. When the cleaning wheel 93 rotates, the mesh opening of the filter 3 can be cleaned. The cleaning wheel 93 is provided with staggered soft rods, and a spring is provided on the inner wall of one end of the rotating shaft 92 close to the cleaning wheel 93, so that when the cleaning wheel 93 rotates, impurities in the mesh opening of the filter 3 can be ejected. The spring cleaning wheel 93 is in closer contact with the filter 3. At the same time, when the filter 3 vibrates, impurities in the mesh opening of the filter 3 can also be ejected to prevent the mesh opening from being blocked.

[0028] In an embodiment of the present utility model, a telescopic block is provided at the lower end of the slider 84, an inclined groove 86 is opened on the telescopic block, a limit block 85 is fixedly connected to the telescopic block, and the size of the inclined groove 86 matches the size of the inclined top block 87, the size of the limit block 85 matches the size of the trapezoidal groove 88, and the limit block 85 is slidably connected to the inner wall of the trapezoidal groove 88, so that when the slider 84 moves to the inclined end of the trapezoidal groove 88, the telescopic block extends to make the cleaning plate 812 descend, and the cleaning plate 812 descends so that the cleaning plate 812 contacts the filter 3, and when the slider 84 moves, the filter 3 is cleaned.

[0029] In an embodiment of the present utility model, the bottom area of ​​the conical block 4 is larger than the area of ​​one end of the vibration motor 5 close to the filter 3, and a folding plate matching the conical block 4 is provided at the center of the cleaning plate 812.

When the slider 84 moves to the vertical end of the trapezoidal groove 88, the push block 814 pushes the baffle 89 to make the impurities fall into the storage box. At this time, the telescopic end of the slider 84 rises, so that the cleaning plate 812 leaves the filter 3, and the limit block 85 moves to the upper end of the trapezoidal groove 88, so that the cleaning plate 812 can clean the impurities in one direction.
