Description

Technical Field

[0001] This application relates to the technical field of screening equipment, and particularly relates to a relaxation sieve for preventing blockage. Background Art

[0002] The relaxation sieve is a type of vibrating sieve, and both are devices for screening and classifying materials using the vibration principle. The vibrating sieve separates materials on the sieve surface by generating vibrations. The elastic sieve surface on the relaxation sieve performs relaxation and tension movements on the inclined sieve box, and the materials are thrown upward through the relaxation and tension movements of the elastic sieve surface, which can reduce the blockage of the sieve mesh and can thus be applied to multiple industries.

[0003] For example, the Chinese patent document with the publication number CN219129917U discloses a single-layer relaxation vibrating sieve, which includes a mounting frame. The function of the mounting frame is to provide a mounting space. A disassembly mechanism is fixedly connected to the right side of the mounting frame, and the function of the disassembly mechanism is to achieve the quick installation and disassembly of the sieve surface. A vibration mechanism is fixedly connected to the left side of the mounting frame, and the function of the vibration mechanism is to provide power for the sieve mesh of the relaxation sieve. When screening materials, the materials are directly dropped from the upper end of the sieve mesh, and then the vibration mechanism drives the sieve mesh to vibrate. While the sieve mesh is vibrating, the sieve mesh throws the materials upward through relaxation and tension movements, thereby realizing the screening of the materials and further reducing the blockage of the sieve mesh.

[0004] In the above related technology, materials can be screened through the vibration and relaxation of the sieve mesh. However, when there are many small particles in the materials, a part of the small particle materials above the sieve mesh will fall simultaneously with the large particle materials, resulting in some small particle materials still remaining in the large particle materials after screening. At this time, in order to improve the screening effect, it is necessary to reduce the falling speed of the materials onto the sieve mesh, so that the number of materials on the sieve mesh in the same time is reduced, and thus the screening effect of the materials can be improved. Since the falling speed of the materials is reduced, the screening efficiency of the materials will be reduced at this time. Summary of the Invention

[0005] This application provides a relaxation sieve for preventing blockage, aiming to solve the problem of reduced material screening efficiency in the related technology.

[0006] The relaxation sieve for preventing blockage provided by this application adopts the following technical solution:

[0007] An anti-clogging shaking screen, comprising a shaking screen body and a screen mesh arranged on the shaking screen body. An installation plate is fixedly installed on the shaking screen body, and the installation plate is arranged above the screen mesh. An installation shell is arranged on the installation plate, and a multi-component partition assembly is arranged on the installation shell. The multi-component partition assembly is arranged at intervals along the width direction of the screen mesh, and the multi-component partition assembly divides the upper part of the screen mesh into multiple screening channels. An adjusting assembly for adjusting the position of the partition assembly is arranged on the installation shell. The partition assembly includes a plurality of first partition plates and a plurality of second partition plates. One end of the first partition plate and the second partition plate are hinged through a partition shaft, and the plurality of first partition plates and the plurality of second partition plates are alternately arranged along the length direction of the screen mesh; a moving rod is slidably connected to the installation shell, and the partition shafts on the multi-component partition assembly are all rotatably connected to the moving rod. When the moving rod moves, the angle of the multi-component partition assembly is adjusted.

[0008] By adopting the above technical solution, in the initial state, the plurality of first partition plates and the plurality of second partition plates of each group of partition assemblies are on the same straight line. At this time, the material falling on the screen mesh has the shortest path during screening; the adjusting assembly on the installation shell can drive the moving rod to move along the length direction of the screen mesh to adjust the position of the moving rod. When the distance between two adjacent moving rods is the closest, the adjacent first partition plate and the second partition plate are vertically arranged. Thus, the number of first partition plates and second partition plates that are vertical can be adjusted by adjusting the number of moving rods that move. The more the number of first partition plates and second partition plates that are vertical, the longer the path of the material on the screen mesh, and then the screening effect of the material on the screen mesh is better.

[0009] Optionally, the adjusting assembly includes a first adjusting roller, a second adjusting roller and a pushing roller rotatably arranged on the installation shell, and an adjusting conveyor belt wound around the first adjusting roller and the second adjusting roller. The axes of the first adjusting roller and the second adjusting roller are arranged in a staggered manner. A plurality of connecting blocks are fixedly installed on the adjusting conveyor belt, and connecting grooves for clamping the connecting blocks are formed on the moving rod; a control assembly for driving the pushing roller to move along the length direction of the adjusting conveyor belt is arranged on the installation shell, and the control assembly is further used to push the connecting blocks on the adjusting conveyor belt into the connecting grooves.

[0010] By adopting the above technical solution, when the connecting block moves into the connecting groove, the adjusting conveyor belt drives the connecting block to rotate, so that the connecting block drives the moving rod above the screen mesh to move at the same time. When the moving rod close to the second adjusting roller moves to the limit position, the adjacent first partition plate and the second partition plate are vertically arranged. Then, the control assembly drives the pushing roller to move towards the direction close to the first adjusting roller. At this time, the moving rod and the connecting groove at the limit position will be separated. Furthermore, during the subsequent movement of the moving rod, the moving rod at the limit position will not be driven to move, so that the adjustment of the length of the screening channel is more convenient.

[0011] Optionally, the control component includes a control screw rotatably connected to the mounting shell, a control block slidably connected to the mounting shell, and a control motor fixed to the mounting shell. The control block slides along the length direction of the screen mesh. The control screw passes through the control block and is threadedly connected to the control block. The pushing roller is rotatably connected to the control block. A tensioning component for keeping the adjusting conveyor belt taut is arranged on the mounting shell.

[0012] By adopting the above technical solution, when the control screw rotates, it drives the control block and the pushing roller rotatably connected to the control block to move, thereby adjusting the lengths of the horizontal part and the inclined part on the adjusting conveyor belt.

[0013] Optionally, the tensioning component includes a tensioning plate slidably connected to the mounting shell, a tensioning roller rotatably connected to the tensioning plate, and a tensioning spring fixed to the tensioning plate. The tensioning roller is arranged between the first adjusting roller and the second adjusting roller, and the tensioning roller abuts against the inner side surface of the adjusting conveyor belt. One end of the tensioning spring away from the tensioning plate is fixed to the mounting shell. The tensioning spring is used to drive the tensioning plate and the tensioning roller to move away from the side surface of the screen mesh.

[0014] By adopting the above technical solution, when the inclined part becomes longer, the tensioning wheel pulls the adjusting conveyor belt to move away from the separating component under the action of the tensioning spring. Thus, during the movement of the pushing roller, the adjusting conveyor belt can always be kept in a taut state, facilitating the connecting block to be better positioned in the connecting groove.

[0015] Optionally, a linkage component for adjusting the positions of the first adjusting roller and the second adjusting roller is arranged on the mounting shell. The linkage component includes a first linkage block, a second linkage block, a linkage shaft, a first linkage rod, and a second linkage rod. The first adjusting roller is rotatably connected to the first linkage block, and the first linkage block is slidably connected to the mounting shell along the width direction of the screen mesh. The second adjusting roller is rotatably connected to the second linkage block, and the second linkage block is slidably connected to the mounting shell along the width direction of the screen mesh. The linkage shaft is fixedly installed on the second linkage rod and is rotatably connected to the mounting plate. There are two first linkage rods. Both first linkage rods are slidably connected to the second linkage rod along the length direction of the screen mesh. One end of a first linkage rod away from the second linkage rod is hinged to the first linkage block, and the other end of the other first linkage rod away from the second linkage rod is hinged to the second linkage block.

[0016] By adopting the above technical solution, when it is necessary to reduce the vertical quantity of the first partition plate and the second partition plate on the screen mesh, by rotating the linkage shaft, the linkage shaft drives the second linkage rod to rotate. At this time, the two first linkage rods will drive the first linkage block and the second linkage block to move, so as to adjust the positions of the first adjusting roller and the second adjusting roller, making the distance between the first adjusting roller and the side of the screen mesh less than the distance between the second adjusting roller and the side of the screen mesh. At this time, the adjusting conveyor belt between the first adjusting roller and the pushing roller is the inclined part, and the adjusting conveyor belt between the second adjusting roller and the pushing roller is the horizontal part. During the reverse movement of the adjusting conveyor belt, it is convenient to pull the moving rod on the screen mesh to move towards the direction close to the storage chamber, and further, the first partition plate and the second partition plate on the screen mesh can be made to be on the same straight line.

[0017] Optionally, a dispersing assembly for dispersing the thrown-up materials is provided on the separating assembly. The dispersing assembly includes a dispersing spring fixedly installed on the first partition plate and a dispersing plate fixed on the dispersing spring.

[0018] By adopting the above technical solution, while the screen mesh and the relaxation screen body vibrate, the free end of the dispersing spring will drive the dispersing plate to swing, and then the thrown-up materials will be dispersed, thereby reducing the situation where the falling materials are piled up, and further improving the screening efficiency of the materials.

[0019] Optionally, a dispersing assembly is provided on each of the first partition plate and the second partition plate.

[0020] By adopting the above technical solution, since a dispersing assembly is provided on each of the first partition plate and the second partition plate, at this time, while the screen mesh and the relaxation screen body vibrate, the materials can be better dispersed.

[0021] Optionally, a swinging assembly for driving the mounting shell to reciprocate is provided on the mounting plate. The swinging assembly includes a swinging disk rotatably connected to the mounting plate, a swinging rod hinged to the swinging disk, and a swinging motor fixed on the mounting plate. The output shaft of the swinging motor is fixed on the swinging disk, and the end of the swinging rod away from the swinging disk is hinged to the mounting shell, and the swinging rod is hinged to a non-central position of the swinging disk.

[0022] By adopting the above technical solution, when the swinging disk rotates, under the action of the swinging rod, the mounting shell is driven to reciprocate along the width direction of the screen mesh, so that the mounting shell drives the separating assembly to reciprocate, and further the separating assembly reciprocally pushes the materials to move, thereby improving the screening efficiency of the materials.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Adjust the number of the first partition plate and the second partition plate that are perpendicular to each other by adjusting the number of the moving rods. The more the number of the first partition plate and the second partition plate that are perpendicular to each other, the longer the path of the material passing through the screen mesh, and then the better the screening effect of the material on the screen mesh.

[0025] 2. While the screen mesh and the relaxation sieve body vibrate, the free end of the dispersing spring will drive the dispersing plate to swing, and then the thrown-up material will be dispersed, so as to reduce the accumulation of the falling material, and thus the screening efficiency of the material can be improved.

Detailed Embodiments

[0034] The following is combined withFigures 1 - 7 Further detailed description of the present application is provided as follows.

[0035] Embodiment 1:

[0036] An embodiment of the present application discloses a clog - proof gyratory screen. Referring to Figure 1 、 Figure 2 and Figure 7 , a clog - proof gyratory screen includes a gyratory screen body 01 and a screen mesh 02 arranged on the gyratory screen body 01. A mounting plate 03 is fixedly installed on the gyratory screen body 01. The mounting plate 03 is arranged above the screening mesh. Additionally, an installation shell 04 is arranged between the mounting plate 03 and the screen mesh 02, and the installation shell 04 is arranged on the mounting plate 03. A multi - component partition assembly 1 is arranged on the installation shell 04. The multi - component partition assembly 1 is arranged at intervals along the width direction of the screen mesh 02. The multi - component partition assembly 1 divides the upper part of the screen mesh 02 into multiple screening channels 05. At the same time, an adjustment assembly 2 is arranged on the installation shell 04. The adjustment assembly 2 is used to adjust the position of the partition assembly 1, so as to change the length of each screening channel 05, thereby increasing the residence time of the material on the screen mesh 02. Under the condition of the same feeding speed, the screening effect of the material is better. Additionally, a feed hopper 06 is arranged on the installation shell 04. The material is conveyed to the feed hopper 06 through a conveyor belt, and then the material falls onto the screen mesh 02 through the feed hopper 06. At this time, the gyratory screen body 01 drives the screen mesh 02 to vibrate to screen the material.

[0037] Referring to Figures 1 to 3 , the partition assembly 1 includes a plurality of first partition plates 11 and a plurality of second partition plates 12. One end of the first partition plate 11 and the second partition plate 12 are hinged through a partition shaft. The plurality of first partition plates 11 and the plurality of second partition plates 12 are arranged alternately along the length direction of the screen mesh 02. At the same time, a moving rod 13 is slidably connected to the installation shell 04. The partition shafts on the multi - component partition assembly 1 are all rotatably connected to the moving rod 13, and the moving rod 13 is slidably connected to the installation shell 04 along the length direction of the screen mesh 02. When the moving rod 13 moves, the angle of the multi - component partition assembly 1 can be adjusted simultaneously. One first partition plate 11 and one second partition plate 12 are arranged between two moving rods 13. By sliding the moving rod 13 on the installation shell 04, the angles of the first partition plate 11 and the second partition plate 12 between two adjacent moving rods 13 can be adjusted.

[0038] In the initial state, multiple first partition plates 11 and multiple second partition plates 12 of each partition assembly 1 are on the same straight line. At this time, the material falling on the sieve 02 has the shortest path during sieving. The adjusting assembly 2 on the installation shell 04 can drive the moving rod 13 to move along the length direction of the sieve 02 to adjust the position of the moving rod 13. When the distance between two adjacent moving rods 13 is the closest, the adjacent first partition plate 11 and second partition plate 12 are vertically arranged. Thus, the number of perpendicular first partition plates 11 and second partition plates 12 can be adjusted by adjusting the number of moving rods 13 that move. The more the number of perpendicular first partition plates 11 and second partition plates 12, the longer the path of the material on the sieve 02, and then the better the sieving effect of the material on the sieve 02.

[0039] When all the first partition plates 11 and second partition plates 12 on the sieve 02 are vertically arranged, the path of the material on the sieve 02 is the longest. At the same time, a storage chamber 3 is provided on the installation shell 04. When the first partition plates 11 and second partition plates 12 on the sieve 02 are on the same straight line, the length of the straightened partition assembly 1 is greater than the length of the sieve 02. At this time, the first partition plates 11 and second partition plates 12 that are more than the length of the sieve 02 are in the storage chamber 3. When the first partition plates 11 and second partition plates 12 on the sieve 02 need to be vertically arranged, the first partition plates 11 and second partition plates 12 in the storage chamber 3 will move out. In addition, in order to reduce the length of the storage chamber 3, the first partition plates 11 and second partition plates 12 in the storage chamber 3 are arranged at an angle.

[0040] Refer to Figures 2 to 5 , the adjusting assembly 2 includes a first adjusting roller 21, a second adjusting roller 22, and a pushing roller 23 that rotate on the installation shell 04, and an adjusting conveyor belt 24 wound around the first adjusting roller 21 and the second adjusting roller 22. An adjusting motor is provided on the installation shell 04. The adjusting motor is connected to the first adjusting roller 21 and is used to drive the first adjusting roller 21 to rotate. In this embodiment, the axes of the first adjusting roller 21 and the second adjusting roller 22 are arranged in a staggered manner. A plurality of connecting blocks 31 are fixedly installed on the adjusting conveyor belt 24. At the same time, a connecting groove 32 is opened on the moving rod 13, and the opening of the connecting groove 32 faces the direction of the adjusting conveyor belt 24. In addition, a control assembly 6 is provided on the installation shell 04. The control assembly 6 is used to drive the pushing roller 23 to move along the length direction of the adjusting conveyor belt 24 and is used to push the connecting block 31 on the adjusting conveyor belt 24 into the connecting groove 32. Thus, the moving rod 13 can be driven by the adjusting conveyor belt 24 to slide on the installation shell 04, and then it is convenient to adjust the position of the moving rod 13. Under the action of the pushing roller 23, the adjusting conveyor belt 24 is divided into a horizontal part 241 and an inclined part 242. The connecting blocks 31 of the horizontal part 241 are in the connecting groove 32, and the connecting blocks 31 of the inclined part 242 are separated from the connecting groove 32.

[0041] When it is necessary to lengthen the path of the screening channel 05, the first partition plate 11 and the second partition plate 12 above the screen 02 need to be vertically arranged. At this time, the linear distance between the first adjusting roller 21 and the side of the screen 02 is made smaller than the linear distance between the second adjusting roller 22 and the side of the screen 02. Then, the adjusting conveyor belt 24 between the first adjusting roller 21 and the pushing roller 23 is a horizontal part 241, and the adjusting conveyor belt 24 between the second adjusting roller 22 and the pushing roller 23 is an inclined part 242. When it is necessary to shorten the path of the screening channel 05, at this time, the distance between the axis of the first adjusting roller 21 and the screening side is smaller than the distance between the axis of the second adjusting roller 22 and the side of the screen 02. The adjusting conveyor belt 24 between the first adjusting roller 21 and the pushing roller 23 is an inclined part 242, and the adjusting conveyor belt 24 between the second adjusting roller 22 and the pushing roller 23 is an inclined part 242. Then, the pushing roller 23 is used to push the connecting block 31 to move into the connecting groove 32, so as to straighten the first partition plate 11 and the second partition plate 12 perpendicular above the screen 02, and then convey the partition assembly 1 to be straightened into the storage chamber 3.

[0042] Refer to Figures 2 to 5 , in order to facilitate the adjustment of the positions of the first adjusting roller 21 and the second adjusting roller 22, a linkage assembly 4 is arranged on the mounting shell 04; while the pushing roller 23 is moving, in order to keep the adjusting conveyor belt 24 always in a taut state, a tensioning assembly 5 for keeping the adjusting conveyor belt 24 taut is arranged on the mounting shell 04.

[0043] Refer to Figures 2 to 5 , the control assembly 6 includes a control screw 61 rotatably connected to the mounting shell 04, a control block 62 slidably connected to the mounting shell 04, and a control motor fixed to the mounting shell 04. The control block 62 slides along the length direction of the screen 02. The output shaft of the control motor is connected to the control screw 61. The control screw 61 is arranged through the control block 62 and is threadedly connected to the control block 62. The pushing roller 23 is rotatably connected to the control block 62. When the control screw 61 rotates, it drives the control block 62 and the pushing roller 23 rotatably connected to the control block 62 to move, so as to adjust the lengths of the horizontal part 241 and the inclined part 242 on the adjusting conveyor belt 24.

[0044] In the initial state, the first partition plate 11 and the second partition plate 12 above the sieve 02 are on the same straight line. At this time, the moving rods 13 above the sieve 02 are all connected to the adjusting conveyor belt 24 through the connecting blocks 31. The distance between the axis of the pushing roller 23 and the axis of the second adjusting roller 22 is the smallest, and at this time, the inclined portion 242 is also the shortest. Then, when it is necessary to adjust the number of the first partition plate 11 and the second partition plate 12 arranged vertically above the sieve 02, the adjusting conveyor belt 24 drives the connecting block 31 and the moving rod 13 to move. At the same time, the pushing roller 23 moves away from the first adjusting roller 21. While the plurality of moving rods 13 are moving, the moving rod 13 close to the second adjusting roller 22 moves to the limit position first. At this time, the corresponding first partition plate 11 and the second partition plate 12 are arranged vertically. The moving rod 13 that has moved to the limit position cannot move further, and the pushing roller 23 moves away from the second adjusting roller 22. The length of the inclined portion 242 between the pushing roller 23 and the second adjusting roller 22 gradually increases. At this time, the connecting block 31 on the inclined portion 242 is disengaged from the connecting groove 32 close to the second adjusting roller 22. As the length of the inclined portion 242 gradually increases, the number of moving rods 13 connected to the adjusting conveyor belt 24 will also decrease. Then, during the continuous movement of the adjusting conveyor belt 24, it drives the adjacent moving rods 13 to continue to move, and so on. According to the need, the number of the first partition plate 11 and the second partition plate 12 arranged vertically on the sieve 02 is adjusted. The more the number of the first partition plate 11 and the second partition plate 12 arranged vertically, the longer the path of the screening channel 05, and at this time, the material screening is more thorough. In this embodiment, the number of the first partition plate 11 and the second partition plate 12 arranged vertically above the sieve 02 is set according to the proportion of large and small particles in the material.

[0045] When it is necessary to reduce the number of the first partition plate 11 and the second partition plate 12 arranged vertically on the sieve 02, the positions of the first adjusting roller 21 and the second adjusting roller 22 are adjusted through the linkage assembly 4, so that the distance between the first adjusting roller 21 and the side of the sieve 02 is less than the distance between the second adjusting roller 22 and the side of the sieve 02. At this time, the adjusting conveyor belt 24 between the first adjusting roller 21 and the pushing roller 23 is the inclined portion 242, and the adjusting conveyor belt 24 between the second adjusting roller 22 and the pushing roller 23 is the horizontal portion 241. During the reverse movement of the adjusting conveyor belt 24, it is convenient to pull the moving rod 13 on the sieve 02 to move towards the direction close to the storage chamber 3, and further, the first partition plate 11 and the second partition plate 12 on the sieve 02 can be on the same straight line. Since the process of the adjusting conveyor belt 24 driving the moving rod 13 to move towards the direction close to the storage chamber 3 is the same as the process of the adjusting conveyor belt 24 driving the moving rod 13 to move away from the storage chamber 3, in this embodiment, the process of the adjusting conveyor belt 24 driving the moving rod 13 to move towards the direction close to the storage chamber 3 will not be described in detail.

[0046] Refer to Figures 2 to 5, the tensioning assembly 5 includes a tensioning plate 51 slidably connected to the mounting shell 04, a tensioning roller 52 rotatably connected to the tensioning plate 51, and a tensioning spring 53 fixed to the tensioning plate 51. The tensioning roller 52 is disposed between the first adjusting roller 21 and the second adjusting roller 22, and the tensioning roller 52 abuts against the inner side of the adjusting conveyor belt 24. One end of the tensioning spring 53 away from the tensioning plate 51 is fixed to the mounting shell 04, so that the tensioning spring 53 is used to drive the tensioning plate 51 and the tensioning roller 52 to move away from the side of the screen 02. Thus, when the inclined portion 242 becomes longer, the tensioning roller 52 pulls the adjusting conveyor belt 24 to move away from the separating assembly 1 under the action of the tensioning spring 53. During the movement of the pushing roller 23, the adjusting conveyor belt 24 can always be kept in a tensioned state, so as to facilitate the connecting block 31 to be better located in the connecting groove 32.

[0047] Referring to Figures 2 to 5 , the linkage assembly 4 includes a first linkage block 41, a second linkage block 42, a linkage shaft 43, a first linkage rod 44 and a second linkage rod 45. The first adjusting roller 21 is rotatably connected to the first linkage block 41, and the first linkage block 41 is slidably connected to the mounting shell 04 along the width direction of the screen 02. The second adjusting roller 22 is rotatably connected to the second linkage block 42, and the second linkage block 42 is slidably connected to the mounting shell 04 along the width direction of the screen 02. The linkage shaft 43 is fixedly installed on the second linkage rod 45. There are two first linkage rods 44. Both of the two first linkage rods 44 are slidably connected to the second linkage rod 45 along the length direction of the screen 02. One end of a first linkage rod 44 away from the second linkage rod 45 is hinged to the first linkage block 41, and the other end of the other first linkage rod 44 away from the second linkage rod 45 is hinged to the second linkage block 42. At the same time, a linkage motor is provided on the mounting shell 04. The output shaft of the linkage motor is fixedly connected to the linkage shaft 43. By rotating the linkage motor, the linkage shaft 43 and the second linkage rod 45 are driven to rotate, so as to adjust the positions of the first adjusting roller 21 and the second adjusting roller 22.

[0048] Referring to Figure 2 and Figure 6 , a dispersing assembly 7 for dispersing the thrown-up materials is provided on the separating assembly 1. The dispersing assembly 7 includes a dispersing spring 71 fixedly installed on the first separating plate 11 and a dispersing plate 72 fixed to the dispersing spring 71. Thus, the end of the dispersing spring 71 fixed to the first separating plate 11 is the fixed end, and the end fixed to the dispersing plate 72 is the free end. Then, while the screen 02 and the relaxation sieve body 01 vibrate, the free end of the dispersing spring 71 will drive the dispersing plate 72 to swing, and then the thrown-up materials will be dispersed, so as to reduce the situation that the falling materials are piled up, and thus the screening efficiency of the materials can be improved. In this embodiment, one dispersing assembly 7 is provided on each of the first separating plates 11 and the second separating plates 12, so as to better improve the screening efficiency of the materials.

[0049] The implementation principle of a clogging-proof relaxation sieve according to an embodiment of the present application is as follows: In the initial state, the screening channel 05 is in a straight state. At this time, the screening channel 05 is the shortest, and the connecting block 31 is located within the connecting groove 32. When it is necessary to increase the length of the screening channel 05, the conveyor belt 24 is adjusted to drive the connecting block 31 to rotate at this time, so that the connecting block 31 drives the moving rod 13 above the screen 02 to move simultaneously. When the moving rod 13 close to the second adjusting roller 22 moves to the limit position, the adjacent first partition plate 11 and the second partition plate 12 are vertically arranged. Then, the control assembly 6 drives the pushing roller 23 to move towards the first adjusting roller 21. At this time, the moving rod 13 and the connecting block 31 in the limit position will disengage. Therefore, during the subsequent movement of the moving rod 13, the moving rod 13 in the limit position will not be driven to move, making it more convenient to adjust the length of the screening channel 05. When reducing the length of the screening channel 05, the distance between the axis of the first adjusting roller 21 and the side of the screen 02 is greater than the distance between the axis of the second adjusting roller 22 and the side of the screen 02. The control assembly 6 drives the pushing roller 23 to move towards the second adjusting roller 22. At this time, the moving rod 13 in the limit position can be driven to move towards the first adjusting roller 21.

[0050] Embodiment Two:

[0051] The difference from Embodiment One is that the material on the screen 02 can be pushed to move along the width direction of the screen 02, thereby improving the screening efficiency of the material.

[0052] Refer to Figure 2 and Figure 7 , the mounting shell 04 is slidably connected to the mounting plate 03 along the width direction of the screen 02. A swing assembly 8 for driving the mounting shell 04 to reciprocate is provided on the mounting plate 03. The swing assembly 8 includes a swing disk 81 rotatably connected to the mounting plate 03, a swing rod 82 hinged to the swing disk 81, and a swing motor 83 fixed to the mounting plate 03. The output shaft of the swing motor 83 is fixed to the swing disk 81. One end of the swing rod 82 away from the swing disk 81 is hinged to the mounting shell 04, and the swing rod 82 is hinged to a non-central position of the swing disk 81. When the swing disk 81 rotates, under the action of the swing rod 82, the mounting shell 04 is driven to reciprocate along the width direction of the screen 02, so that the mounting shell 04 drives the partition assembly 1 to reciprocate, thereby reciprocatingly pushing the material to move, and thus improving the screening efficiency of the material.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
