Description

Technical Field

[0001] The utility model relates to the technical field of crushed material screening, in particular to a crushed material screening vibration device. Background Art

[0002] Crushed material screening, also known as crushed material screening, is an important link in the material handling process. It is mainly used to classify crushed materials with a wide particle size range according to their particle size.

[0003] In most cases, operators perform screening manually. When screening, first, spread the crushed material evenly on the screen to ensure that the material layer thickness is moderate for screening. Operators can manually shake, flip or vibrate the screen to separate the material on the screen, and the fine particles will pass through the screen holes and fall to the ground below to be cleaned, while the coarse particles will remain on the screen for storage and collection.

[0004] The existing manual screening of crushed materials requires workers to frequently bend over, lift and other actions, which has high labor intensity and is likely to affect the workers' health, and the screening efficiency is low. Therefore, we propose a new type of crushed material screening vibration device. Utility Model Content

[0007] Furthermore, the two groups of electric push rods are the same group of control switches, and the outer surface of the slider is in contact with the inner surface wall of the slide groove.

[0008] Furthermore, a sliding connection is formed between the sliding block and the sliding groove, and an elastic structure is formed between the first pushing block and the first spring through the fixing block.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1 - Figure 5 As shown, the utility model provides a crushing material screening vibration device, including an operating table 1, a screening vibration component 2 is arranged on the surface of the operating table 1, and the screening vibration component 2 includes a slide 201. The front and rear end surfaces of the operating table 1 are both provided with slides 201, and a slider 202 is arranged inside the slide 201. The top of the slider 202 is connected to a moving frame 203, and the inside of the moving frame 203 is connected to a screen 204. Two sets of electric push rods 205 are plugged into one side of the operating table 1, and the inner wall of the other side of the operating table 1 is connected to the screen 204. Two groups of fixed blocks 206 are connected, a first spring 207 is arranged inside the fixed block 206, one side of the first spring 207 is connected to a first push block 208, one side of the first push block 208 is connected to a top block 209, the two groups of electric push rods 205 are the same group of control switches, the outer surface of the slider 202 is in contact with the inner surface wall of the slide groove 201, the slider 202 and the slide groove 201 form a sliding connection, and the first push block 208 forms an elastic structure through the fixed block 206 and the first spring 207.

[0026] The effect achieved by the entire embodiment 1 is that when it is necessary to screen the crushed materials, the crushed materials to be screened can be poured on the surface of the screen 204, and then the telescopic function of the electric push rod 205 is turned on, so that the electric push rod 205 can push the moving frame 203 back and forth. When the moving frame 203 moves, it will also drive the slider 202 to slide in the slider 202, thereby improving the stability of the moving frame 203 when moving. When the moving frame 203 contacts the top block 209, it will push the first push block 208 to squeeze the first spring 207, which plays a buffering role, so as to prevent the moving frame 203 from directly colliding with one side of the operating table 1 and causing damage. The crushed materials are screened by the vibration generated when the moving frame 203 moves back and forth, and all the fine crushed materials are screened to the ground, while the larger crushed materials can be left on the surface of the screen 204 and collected, thus avoiding the time-consuming and labor-intensive problem of manual screening of the crushed materials, reducing the labor intensity of the operators, and improving the screening efficiency of the crushed materials.

[0027] Embodiment 2, as Figure 1 , Figure 2 and Figure 6 As shown, the front and rear end outer surfaces of the movable frame 203 are both provided with disassembly and assembly components 3, and the disassembly and assembly components 3 include a connecting block 301, and two groups of second springs 302 are connected to the interior of the connecting block 301, and a pull rod 303 is inserted into the interior of the second spring 302, one end of the two groups of pull rods 303 is connected to a handle 304, and the other end of the two groups of pull rods 303 is connected to a second push block 305, and one side of the second push block 305 is connected to an insertion block 306, and the front and rear end outer surfaces of the screen 204 are both provided with a socket 307, the position and size of the socket 307 match the position and size of the insertion block 306, and a snap-fit ​​connection is formed between the insertion block 306 and the socket 307.

[0028] The effect achieved by the entire embodiment 2 is that when the screen 204 needs to be replaced, the two sets of handles 304 can be pulled outward, so that the handles 304 can drive the plug block 306 to be pulled out from the socket 307, and then the existing screen 204 can be removed, and the new screen 204 can be pushed into the movable frame 203. At this time, the oblique position of the plug block 306 will be squeezed and contracted. When the new screen 204 is completely pushed into the movable frame 203, the second spring 302 will push the second push block 305 through its own elastic force to drive the plug block 306 to be automatically inserted into the socket 307, thereby realizing the rapid disassembly and assembly of the screen 204, avoiding the problem that the existing screen 204 is fixed by bolts, which is very inconvenient when replacing.

[0029] Working principle: when it is necessary to screen the crushed materials, the crushed materials can be poured onto the surface of the screen 204, and then the telescopic function of the electric push rod 205 can be turned on to push the mobile frame 203 back and forth, and the vibration generated back and forth can screen the crushed materials, thus avoiding the time-consuming and labor-intensive problem of manual screening, reducing the labor intensity of operators, and improving the screening efficiency of the crushed materials. When it is necessary to replace the screen 204, the two sets of handles 304 can be pulled outward so that the plug block 306 can be pulled out of the socket 307, and then the existing screen 204 can be removed, and the new screen 204 can be pushed into the mobile frame 203, so that the plug block 306 can be automatically inserted into the socket 307, thereby realizing the rapid disassembly and assembly of the screen 204, and avoiding the problem that the existing screen 204 is fixed by bolts, which is very inconvenient when replacing.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
