[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen for sand and gravel processing which is easy to disassemble and assemble. Background Art

[0002] Sand and gravel refers to a loose mixture of sand and crushed stone. Due to its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. Nowadays, a large amount of sand and gravel concrete is needed in urban engineering construction, road construction and other construction projects. Different engineering constructions have different requirements for the particle size and uniformity of sand and gravel, so a large amount of sand and gravel screening operations will be involved in civil engineering projects;

When the screen is damaged, the screen with an integral structure and connected by bolts is not easy to disassemble and repair, which affects the maintenance efficiency of the maintenance personnel on the vibrating screen.

[0004] In order to solve the above problems, the present application proposes a vibrating screen for sand and gravel processing which is easy to disassemble and assemble. Utility Model Content

[0005] The utility model aims to provide a vibrating screen for sand and gravel processing which is easy to disassemble and assemble, and is mainly used to solve the problem that the existing vibrating screen meshes are all integral structures, and are connected to the vibrating screen main structure by bolts on both sides. When the screen mesh is damaged, it is not convenient to disassemble and repair the screen mesh.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A vibrating screen for sand and gravel processing that is easy to disassemble and assemble comprises a hopper and a plurality of supporting legs fixedly connected to the bottom of the hopper, a frame is inserted on one side of the hopper, a screen is fixedly connected to the inner wall of the frame, a through slot matching the frame is provided on one side of the hopper, a slot matching the frame is provided on the side of the inner wall of the hopper away from the through slot, guide blocks are fixedly connected on both sides of the frame, guide slots matching the guide blocks are provided on both sides of the inner wall of the hopper, a limit assembly for fixing the frame is fixedly connected to one side of the hopper, and a vibration assembly is fixedly connected to the other side of the hopper.

[0008] The working principle and beneficial effects of the utility model:

[0009] 1. Working principle: When the device is in operation, sand and gravel are added into the hopper and the vibration component is started at the same time. The operation of the vibration component can make the screen vibrate to a certain extent, thereby realizing the screening operation of sand and gravel. When the screen needs to be disassembled for maintenance, the frame can be pulled out from the hopper. After the screen is repaired, the frame is inserted into the hopper through the through slot. The limit assembly can play a better limiting role on the screen, and the device can be used normally.

[0010] 2. Beneficial effects: The frame is inserted into the hopper, and the inner wall of the frame is fixedly connected with a screen, so that people can remove the frame from the inside of the hopper, which is convenient for people to repair or replace the screen. After the frame is inserted into the hopper, the limit assembly can play a better fixing role on it, so that the device is more stable during operation. When the device is operating, the vibration assembly can cause the screen to vibrate to a certain extent, which can not only improve the screening efficiency of the device for sand and gravel, but also effectively prevent the screen from being blocked.

[0011] Preferably, the limit assembly includes a symmetrical fixed block fixedly connected to one side of the hopper, a sliding cavity is provided at the bottom of the fixed block, the internal sliding connection of the sliding cavity is slidably connected to the limit block, the bottom of the limit block extends out of the fixed block, the top of the limit block is fixedly connected with a symmetrical first spring, the upper end of the first spring is fixedly connected to the top of the inner wall of the sliding cavity, a pull rod is fixedly connected at the center of the top of the limit block, the upper end of the pull rod passes through the fixed block and is slidably connected to the fixed block, and one end of the pull rod extending out of the fixed block is fixedly connected to a pull ring, a symmetrical slide groove is provided on the outer wall of the pull rod, a wedge block is slidably connected to the inside of the slide groove, a pull rod extends from one side of the wedge block, and the other side is fixedly connected to a second spring, the other end of the second spring is fixedly connected to the inner wall of the slide groove, when the screen needs to be repaired or replaced, the pull ring can be pulled upwards to drive the limit block to slide upwards through the pull rod, and at the same time squeeze the first The spring puts it in a compressed state. When the pull rod moves upward, the wedge block is squeezed by the fixed block and moves into the slide groove, while squeezing the second spring to put it in a compressed state. When the limit block completely enters the slide cavity, the wedge block will pop out under the action of the second spring and engage with the fixed block, which can better fix the pull rod and the limit block. At this time, the frame can be removed from the hopper, which is convenient for people to repair or replace the screen. After the screen is repaired, the frame is inserted into the hopper through the through slot, and then the two wedge blocks on the pull rod are pressed at the same time to make them slide into the slide groove. After the wedge block completely enters the slide groove, the limit block will pop out under the action of the first spring, which can better fix the frame. This not only makes it more convenient for people to disassemble the frame, but also makes the device more stable during operation.

[0012] Preferably, the vibration assembly includes a mounting base fixedly connected to one side of the hopper, a motor fixedly installed on the top of the mounting base, a rotating shaft fixedly connected to the output end of the motor, the rotating shaft extends to a side of the inner wall of the hopper away from the motor, the rotating shaft is rotatably connected to the hopper, a symmetrical fixing sleeve is fixedly connected to the outer wall of the fixing sleeve, a connecting rod is fixedly connected to the outer wall of the fixing sleeve, and a vibration roller is rotatably connected between the connecting rods on the two fixing sleeves. When the device is in operation, sand and gravel are added to the hopper and the motor is started at the same time. The movement of the motor can rotate the rotating shaft. When the rotating shaft rotates, the vibration roller can be driven to move in a circle inside the hopper through the fixed sleeve and the connecting rod. When the vibration roller moves in a circle inside the hopper, it will hit the screen, thereby causing the screen to vibrate to a certain extent. This can not only improve the screening efficiency of the device for sand and gravel, but also effectively prevent the screen from being blocked.

[0013] Preferably, the number of connecting rods on the outer wall of the fixed sleeve is three, and the connecting rods are equidistantly distributed on the fixed sleeve in a circular array. By setting the number of connecting rods on the outer wall of the fixed sleeve to three, the number of vibrating rollers is matched with the connecting rods. The advantage of such a setting is that the vibration efficiency of the screen during the operation of the device can be effectively improved, thereby further improving the screening efficiency of the device for sand and gravel.

[0014] Preferably, the number of second springs inside the slide groove is not less than three, and the second springs are evenly distributed in a linear array inside the slide groove. By setting the number of second springs inside the slide groove to be not less than three, the elastic force of the second spring on the wedge block can be greater, thereby achieving a better fixing effect on the pull rod when the wedge block is engaged with the fixed block.

[0015] Preferably, a plurality of protrusions are fixedly connected to the outer wall of the vibration roller, and the protrusions are equidistantly distributed on the vibration roller. By means of the plurality of protrusions arranged on the vibration roller, when the vibration roller moves in a circular motion inside the hopper and hits the screen, the vibration amplitude of the screen can be further increased, which can have a better vibration effect on the screen, thereby further improving the screening efficiency of sand and gravel.
