[0002] A rolling screen, usually called a drum screen, is a machine widely used in sorting technology. It realizes the sorting of garbage or materials by controlling the particle size of particles, and has the characteristics of high sorting accuracy, stable operation, and low noise.
[0003] In the screening of coarse-grained sand-like materials, rolling screens are often used for the classification of materials. Due to the blockage of the screen mesh by coarse-grained materials during the screening process, the efficiency and accuracy of the next screening are hindered. It is necessary to clean the blocked materials regularly. At the same time, sand-like materials are prone to agglomeration, and manual secondary crushing and separation are required, which reduces the work efficiency and increases the production cost. Therefore, a device that can both crush sand blocks to make their particle sizes uniform for subsequent processes and clean the materials stuck in the screen holes is proposed.

[0006] A cleaning device is arranged on the upper surface of the bottom plate. The cleaning device includes a cleaning tooth plate, and the lifting of the cleaning tooth plate pushes the materials in the screen holes of the screen.
[0007] Preferably, the scraping device further includes a motor. The motor is fixedly installed on the upper surface of the bottom plate through a support plate. A connecting frame is fixedly installed on the upper surface of the bottom plate. The outer surface of the connecting frame is rotatably connected with a transmission bevel gear through a bearing. One end of the output shaft of the motor is fixedly installed with a transmission rod with a bevel gear through a coupling. The bevel gear of the transmission rod meshes with the transmission bevel gear. The scraper is fixedly installed on the outer surface of the transmission rod, and a ball is rotatably connected to the inner wall of the scraper.
[0008] Through the above technical solution, the motor is a variable-speed motor, which can rotate at a high speed during screening and at a low speed during cleaning. The motor drives the rotating rod with bevel gears to rotate, and at the same time drives the screen to rotate. The motor drives the rotating rod and the screen to rotate in reverse synchronously. The scraper fixedly installed on the outer surface of the rotating rod rotates in reverse synchronously with the screen, so as to scrape the materials in the mesh holes at different positions of the screen. Through the meshing of the bevel gear of the rotating rod with the transmission bevel gear, the bevel gear of the rotating rod drives the transmission bevel gear to rotate when rotating, achieving the effect that one motor can drive the screen, the rotating rod and the transmission bevel gear to rotate at the same time, and reducing the production cost of the equipment.

Through the meshing of the bevel gear of the screen with the transmission bevel gear, the screen and the transmission bevel gear rotate synchronously. Through the outer surfaces of the scraper and the ball being both in contact with the inner wall of the screen, the ball arranged in the scraper is used to crush the powdery materials in the screen, and one side of the scraper is longer and can be in contact with the inner wall of the screen, so as to scrape the materials that have not been crushed by the ball.
[0011] Preferably, the cleaning device further includes a gearbox, the gearbox is fixedly installed on the upper surface of the bottom plate, and the input shaft of the gearbox is fixedly installed with one end of the transmission bevel gear through a coupling.
[0012] Through the above technical solution, one end of the transmission bevel gear is fixedly installed on the input shaft of the gearbox through a coupling. The gearbox is set to a speed ratio of 1:10. At this time, the speed of the output shaft of the gearbox will be 10 times that of the input shaft.

A driving gear is slidably inserted into the output shaft of the gearbox. The outer surface of the driving gear is magnetically connected to the outer surface of the adsorption electromagnet. After the adsorption electromagnet is energized, it will generate magnetic force. Under the action of the magnetic force, the driving gear will be magnetically connected to another adsorption electromagnet through the adsorption electromagnet, so that the driving gear meshes with the lifting gear. Thus, the rotation of the driving gear drives the lifting gear to rotate. The gear speed ratio of the driving gear to the lifting gear is within the range of 1:5-10, which facilitates the cooperation of the gearbox and the driving gear to enable the screen to rotate one circle, and the lifting gear drives the cleaning tooth plate to insert all the screen holes on the screen once. After the adsorption electromagnet is powered off, the spring will reset the driving gear, so that the lifting gear stops working.
[0015] Preferably, a slide rail is fixedly installed on the upper surface of the bottom plate, and both ends of the cleaning tooth plate are slidably inserted into the outer surfaces of the two slide rails respectively.
[0016] Through the above technical solution, the slide rail fixedly installed on the upper surface of the bottom plate enables the cleaning tooth plate to lift, thereby pushing the materials in the screen holes of the screen, achieving the effect of cleaning the rotary screen.
[0017] Preferably, a connecting rod is hinged to the outer surface of the lifting gear through a pin shaft, and one end of the connecting rod is hinged to one end of the cleaning tooth plate through a pin shaft.

The motor simultaneously drives the transmission rod and the screen to rotate in reverse synchronously, so that the scraper fixedly installed on the outer surface of the transmission rod rotates in reverse synchronously with the screen, which can scrape the materials in the inner wall holes of the screen. The outer surface of the scraper and the outer surface of the ball are in contact with the inner wall of the rotary screen, so that the scraper and the ball inside the scraper crush the materials entering the screen during the working process of the rotary screen, so that the materials that do not meet the requirements do not need to be manually rolled again, greatly reducing the production cost, and solving the technical problem that the existing sand-like materials will agglomerate and need to be manually rolled again.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0028] Refer to Figures 1-4 , an efficient rolling screen cleaning device, including a bottom plate 1 and a sieve 2 with bevel gears. A scraping device is provided on the upper surface of the bottom plate 1. The scraping device includes a scraper 3, and the rotation of the scraper 3 scrapes the materials in the mesh holes of the sieve 2.
[0029] For the transmission rod 34 with bevel gears to be able to rotate, the scraping device further includes a motor 31. The motor 31 is fixedly installed on the upper surface of the bottom plate 1 through a support plate. The motor 31 is a variable-speed motor that can rotate at a high speed during screening and at a low speed during cleaning. The motor 31 can simultaneously drive the transmission rod 34 and the screen 2 to rotate in reverse synchronously. The scraper 3 fixedly installed on the outer surface of the transmission rod 34 rotates in reverse synchronously with the screen 2, thereby scraping the materials in the mesh holes at different positions of the screen 2. A connecting frame 32 is fixedly installed on the upper surface of the bottom plate 1. A transmission bevel gear 33 is rotatably connected to the outer surface of the connecting frame 32 through a bearing. One end of the output shaft of the motor 31 is fixedly installed with a transmission rod 34 with bevel gears through a coupling. In order for the motor 31 to also drive the transmission bevel gear 33 to rotate, the bevel gear of the transmission rod 34 meshes with the transmission bevel gear 33, achieving the effect that one motor 31 can simultaneously drive the screen 2, the transmission rod 34 and the transmission bevel gear 33 to rotate, reducing the production cost of the equipment.
[0030] In order for the screen 2 and the transmission bevel gear 33 to rotate synchronously, the outer surfaces of the two connecting frames 32 are respectively rotatably connected to both ends of the screen 2 through bearings. The bevel gear of the screen 2 meshes with the transmission bevel gear 33. In order to crush the agglomerated materials, the outer surfaces of the scraper 3 and the ball 35 are both in contact with the inner wall of the screen 2, and one side of the scraper 3 is longer, which is used to scrape the materials that have not been crushed by the ball 35.
[0031] By setting the scraping device to scrape the materials in the mesh holes of the screen 2, start the motor 31 to drive the transmission rod 34 with bevel gears to rotate. The scraper 3 is fixedly installed on the outer surface of the transmission rod 34. The rotation of the transmission rod 34 drives the scraper 3 to rotate. The outer surface of the scraper 3 and the outer surface of the ball 35 are in contact with the inner wall of the screen 2, so that the scraper 3 and the ball 35 inside the scraper 3 crush the powdery materials entering the screen 2 during the rotation process, so that the materials that do not meet the requirements do not need secondary processing, greatly reducing the production cost.
[0032] In order for the cleaning tooth plate 4 to be able to lift and lower multiple times when the motor 31 drives the transmission rod 34 to rotate one circle, the cleaning device further includes a gearbox 41. The gearbox 41 is fixedly installed on the upper surface of the bottom plate 1. The input shaft of the gearbox 41 is fixedly installed with one end of the transmission bevel gear 33 through a coupling. The gearbox 41 is set with a speed ratio of 1:10. At this time, the rotational speed of the output shaft of the gearbox 41 will be 10 times that of the input shaft.
[0033] In order to make the driving gear 44 drive the rotation of the lifting gear 45, an adsorption electromagnet 42 is fixedly installed at one end of the output shaft of the gearbox 41. A spring 43 is fixedly installed on the outer surface of the adsorption electromagnet 42. One end of the gearbox 41 is slidably inserted with a driving gear 44. The outer surface of the driving gear 44 is magnetically connected to the outer surface of the adsorption electromagnet 42. After the adsorption electromagnet 42 is energized, it will generate a magnetic force. Under the action of the magnetic force, the driving gear 44 will be magnetically connected to another adsorption electromagnet 42 through the adsorption electromagnet 42, so that the driving gear 44 meshes with the lifting gear 45. Thus, the rotation of the driving gear 44 drives the lifting gear 45 to rotate. The gear speed ratio of the driving gear 44 to the lifting gear 45 is in the range of 1:5 - 10. It is convenient to make the screen 2 rotate one circle through the cooperation of the gearbox 41 and the driving gear 44, and the lifting gear 45 drives the cleaning tooth plate 4 to insert all the sieve holes on the screen 2 once. After the adsorption electromagnet 42 is powered off, the spring 43 will reset the driving gear 44, so that the lifting gear 45 stops working.
[0034] In order to make the cleaning tooth plate 4 perform a lifting motion, a slide rail 46 is fixedly installed on the upper surface of the bottom plate 1. The two ends of the cleaning tooth plate 4 are respectively slidably inserted into the outer surfaces of the two slide rails 46.
[0035] In order to make the rotation of the lifting gear 45 drive the connecting rod 47 to deflect, the outer surface of the lifting gear 45 is hinged with a connecting rod 47 through a pin shaft. One end of the connecting rod 47 is hinged with one end of the cleaning tooth plate 4 through a pin shaft. Thus, the up and down deflection of the connecting rod 47 drives the cleaning tooth plate 4 to lift on the slide rail 46. The tooth plate on the cleaning tooth plate 4 is conical, so as to facilitate cleaning the materials in the sieve holes of different sizes of the screen 2.
[0036] By setting up the cleaning device to push the materials in the sieve holes of the screen 2, start the motor 31 to drive the transmission rod 34 with a bevel gear to rotate. The bevel gear on the transmission rod 34 meshes with the transmission bevel gear 33. One end of the transmission bevel gear 33 is fixedly installed with the input shaft of the gearbox 41 through a coupling. It is convenient to make the screen 2 rotate one circle through the cooperation of the gearbox 41 and the driving gear 44, and the lifting gear 45 drives the cleaning tooth plate 4 to insert all the sieve holes on the screen 2 once. The outer surface of the lifting gear 45 is hinged with a connecting rod 47 through a pin shaft. One end of the connecting rod 47 is hinged with one end of the cleaning tooth plate 4 through a pin shaft. A slide rail 46 is fixedly installed on the upper surface of the bottom plate 1. The two ends of the cleaning tooth plate 4 are respectively slidably inserted into the outer surfaces of the two slide rails 46. Thus, the lifting gear 45 drives the cleaning tooth plate 4 to lift. When the motor 31 drives the transmission rod 34 and the screen 2 to rotate once, the cleaning tooth plate 4 will lift multiple times, achieving the effect of effectively cleaning the materials stuck in the sieve holes of the screen 2, keeping the sieve holes unobstructed, thereby improving the screening efficiency. And the cleaning tooth plate 4 on the cleaning device is conical, so that the cleaning tooth plate 4 can clean the sieve holes of different sizes of the screen 2.
[0037] Working principle: When it is necessary to screen the material, after the motor 31 on the bottom plate 1 drives the transmission rod 34 to rotate, the bevel gear on the transmission rod 34 drives the bevel gear on the screen 2 to rotate through the transmission bevel gear 33 on the connecting frame 32, so as to drive the transmission rod 34 and the screen 2 to rotate synchronously and in opposite directions. The rotation of the transmission rod 34 will drive the scraper 3 to scrape the material on the inner wall of the screen 2. The ball 35 arranged inside the scraper 3 will crush the caked material in the screen 2. After the crushed material is scraped by the scraper 3, it is convenient for screening;
[0038] When it is necessary to clean the screen 2, after starting the motor 31, adjust the speed of the motor 31. The rotation of the motor 31 drives the transmission bevel gear 33 to rotate. One end of the transmission bevel gear 33 is fixedly installed on the input shaft of the gearbox 41 through a coupling, so that the speed of the driving gear 44 is increased. After the adsorption electromagnet 42 is energized, under the action of magnetic force, the driving gear 44 will move towards the lifting gear 45 on the output shaft of the gearbox 41 through the adsorption electromagnet 42 and engage with the lifting gear 45. The spring 43 is compressed, so as to drive the lifting gear 45 to rotate through the rotation of the driving gear 44. The rotation of the lifting gear 45 will drive the connecting rod 47 to deflect. The deflection of the connecting rod 47 will drive the cleaning tooth plate 4 to lift on the slide rail 46, so as to push the material in the mesh holes of the screen 2. After the adsorption electromagnet 42 is powered off, the spring 43 will reset the driving gear 44, so that the lifting gear 45 stops working.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
