Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a screening device for separating materials. Background Technology

[0002] Screening equipment is a type of mechanical equipment used to separate materials according to particle size. It is widely used in many industries such as mining, metallurgy, chemical industry, food, medicine, and environmental protection. It is mainly used to separate particles of different sizes in mixed materials for subsequent processing or use. Cleaning the screening equipment is an important part of ensuring the normal operation of the equipment and screening efficiency. It can effectively maintain the good condition of the screening equipment and provide reliable protection for industrial production.

[0003] Existing screening equipment is prone to reduced efficiency due to material accumulation during material separation. If the residual material on the screen is not cleaned in time after screening, it can easily cause screen blockage. Long-term blockage will accelerate equipment wear and significantly shorten its service life. To solve the above problems, we propose a screening equipment for separating materials. Utility Model Content

[0004] The main objective of this invention is to provide a screening device for separating materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A screening device for separating materials includes a screening frame, a collection box slidably connected to the inner side of the screening frame, a screen fixedly connected to the inner side of the screening frame, a rack and a first sliding groove fixedly connected to the front end of the screening frame, two sets of second sliding grooves fixedly connected to the upper end of the screening frame, a cleaning mechanism and a leveling mechanism provided at the front end of the screening frame, the cleaning mechanism including a first support and a brush, the brush being movably connected to the upper end of the screen, and the leveling mechanism including a second support and a scraper, the scraper being slidably connected to the upper end of the screen.

[0007] Preferably, the first bracket is slidably connected to the inner side of the first slide groove, a first motor is installed on the inner side of the first bracket, and a cam is fixedly connected to the output end of the first motor.

[0008] Preferably, the outer side of the cam has a groove, the rear end of the cam is fixedly connected to a first gear, the first gear meshes with a rack, and the outer side of the cam is rotatably connected to a protective shell.

[0009] Preferably, the outer side of the protective shell has an opening, and a slide rod is slidably connected to the inner side of the opening. The lower end of the slide rod extends through the opening to the inner side of the groove, and the slide rod is slidably connected to the inner side of the groove.

[0010] Preferably, the upper end of the slide bar is fixedly connected to a first connecting rod, the first connecting rod is slidably connected to the inner side of the second slide groove, and the first connecting rod is fixedly connected to the front end of the brush.

[0011] Preferably, the second bracket is slidably connected to the inner side of the first slide groove, a second motor is installed on the inner side of the second bracket, the output end of the second motor is fixedly connected to the rotating block, and the rear end of the rotating block is fixedly connected to the second gear, which meshes with the rack.

[0012] Preferably, a connecting ring is rotatably connected to the outer side of the rotating block, a fixing block is fixedly connected to the outer side of the connecting ring, a second connecting rod is fixedly connected to the upper end of the fixing block, the second connecting rod is slidably connected to the inner side of the second slide groove, and the second connecting rod is fixedly connected to the upper end of the scraper.

[0013] Compared with the prior art, this utility model has the following beneficial effects: In use, the second motor is started to rotate the second gear. The second gear, through meshing with the rack and pinion, rolls at the front end of the screening frame, causing the scraper to slide above the screen, flattening the material and preventing accumulation. The material is then screened through the screen into the collection box. After the worker transfers the screened material in the collection box, the scraper stops at the other end of the screening frame. Then, the first motor is started to drive the cam and groove to rotate simultaneously. The groove, through meshing with the rack and pinion... The front end of the screening frame rolls, causing the first connecting rod to slide left and right inside the second slide groove. Simultaneously, the rotation of the cam causes the slide bar to slide within the opening, which in turn causes the first connecting rod to move back and forth inside the second slide groove. This allows the brush to move left and right and back and forth simultaneously at the top of the screen, cleaning the screen. This invention can evenly flatten the material during screening, effectively preventing material accumulation. At the same time, it cleans the screen after screening to avoid screen blockage. This not only ensures the efficient completion of screening and cleaning operations but also significantly extends the service life of the equipment. Attached Figure Description

[0022] In this embodiment, the first bracket 71 is slidably connected to the inner side of the first slide groove 5, the inner side of the first bracket 71 is equipped with a first motor 72, and the output end of the first motor 72 is fixedly connected to a cam 73.

[0023] Specifically, the first bracket 71 will slide inside the first slide groove 5, and starting the first motor 72 will drive the cam 73 to rotate.

[0024] In this embodiment, a groove 74 is provided on the outer side of the cam 73, and a first gear 75 is fixedly connected to the rear end of the cam 73. The first gear 75 meshes with the rack 4, and a protective shell 76 is rotatably connected to the outer side of the cam 73.

[0025] Specifically, the cam 73 drives the first gear 75 to rotate, and the first gear 75 will roll at the front end of the screening frame 1 by meshing with the rack 4, thereby causing the protective shell 76 to move.

[0026] In this embodiment, an opening 77 is provided on the outer side of the protective shell 76, and a slide rod 78 is slidably connected to the inner side of the opening 77. The lower end of the slide rod 78 extends through the opening 77 to the inner side of the groove 74, and the slide rod 78 is slidably connected to the inner side of the groove 74.

[0027] Specifically, when the cam 73 rotates inside the protective shell 76, the groove 74 drives the slide bar 78 to reciprocate within the opening 77.

[0028] In this embodiment, the upper end of the slide bar 78 is fixedly connected to the first connecting rod 79, the first connecting rod 79 is slidably connected to the inner side of the second slide groove 6, and the first connecting rod 79 is fixedly connected to the front end of the brush 710.

[0029] Specifically, the slide rod 78 drives the first connecting rod 79 to move left and right and back and forth simultaneously inside the second slide groove 6, which further drives the brush 710 to move left and right and back and forth simultaneously on the upper surface of the screen 3, so as to clean the screen 3 in time and prevent the screen 3 from becoming blocked.

[0030] In this embodiment, the second bracket 81 is slidably connected to the inner side of the first slide groove 5, and the second motor 82 is installed on the inner side of the second bracket 81. The output end of the second motor 82 is fixedly connected to the rotating block 83, and the rear end of the rotating block 83 is fixedly connected to the second gear 84, which meshes with the rack 4.

[0031] Specifically, by starting the second motor 82 to drive the rotating block 83 to rotate, the second gear 84 is driven to rotate. The second gear 84 rolls on the surface of the screening frame 1 by meshing with the rack 4, so that the rotating block 83 moves while rotating. At this time, the second support 81 slides inside the first slide groove 5.

[0032] In this embodiment, a connecting ring 85 is rotatably connected to the outer side of the rotating block 83, a fixing block 86 is fixedly connected to the outer side of the connecting ring 85, a second connecting rod 87 is fixedly connected to the upper end of the fixing block 86, the second connecting rod 87 is slidably connected to the inner side of the second slide groove 6, and the second connecting rod 87 is fixedly connected to the upper end of the scraper 88.

[0033] Specifically, the movement of the rotating block 83 can cause the connecting ring 85 to move, thereby driving the fixed block 86 to move, and further causing the second connecting rod 87 to slide inside the second sliding groove 6, so that the scraper 88 slides at the upper end of the screen 3, pushing the material through and preventing material accumulation.

[0034] It should be noted that this utility model is a screening device for separating materials. In use, the material enters the surface of the screen 3 through the feed inlet. The second motor 82 is started, driving the rotating block 83 to rotate, which in turn drives the second gear 84 to rotate. The second gear 84 rotates at the front end of the screening frame 1 by meshing with the rack 4. At this time, the second support 81 slides inside the first slide groove 5, driving the connecting ring 85 to move. This, through the fixing block 86, drives the second connecting rod 87 to slide inside the second slide groove 6, causing the scraper 88 to slide above the screen 3, pushing the material flat and screening it through the screen 3 into the collection box 2. The worker then transfers the screened material from the collection box 2 and pushes the collection box 2 back inside the screening frame 1. Finally, the scraper 88 stops on the screening machine. At the other end of frame 1, the first motor 72 is started to drive the cam 73 and the first gear 75 to rotate simultaneously. The first gear 75 rolls at the front end of the screening frame 1 by meshing with the rack 4. At this time, the first support 71 slides inside the first slide groove 5, thereby driving the protective shell 76 to move. It also drives the first connecting rod 79 to slide left and right inside the second slide groove 6 through the slide rod 78. At the same time, the cam 73 continues to rotate, causing the slide rod 78 to slide inside the opening 77, further driving the first connecting rod 79 to move back and forth inside the second slide groove 6. This causes the brush 710 to move left and right and back and forth simultaneously at the upper end of the screen 3, completing the cleaning work of the screen 3. After cleaning is completed, the first motor 72 and the second motor 82 are reversed to output, so that the cleaning mechanism 7 and the leveling mechanism 8 are reset to the starting position.
