Description

Technical Field

[0001] The present invention relates to the technical field of vibrating screens, and in particular to a protective structure for a vibrating screen. Background Art

[0002] Currently, a vibrating screen operates by the reciprocating spiral vibration generated by the excitation of the vibrators on the vibrator. The upper rotating weight of the vibrator causes the screen surface to generate a planar gyratory vibration, while the lower rotating weight causes the screen surface to generate a conical gyratory vibration. The combined effect makes the screen surface generate a compound spiral vibration.

[0003] In the related art, a protective cover needs to be configured for the vibrator on the vibrating screen. However, the protective cover only plays a protective role. When maintaining the vibrator, personnel need to enter the interior of the vibrating screen to remove the protective cover of the vibrator and disconnect the connection between the vibrator and the coupling, which is inconvenient for maintenance. Therefore, it needs to be improved. Summary of the Invention

[0004] In order to facilitate the maintenance of the vibrator, the present application provides a protective structure for a vibrating screen.

[0005] The protective structure for a vibrating screen provided by the present application adopts the following technical solution: A protective structure for a vibrating screen includes a machine body and bearing holes symmetrically opened on the machine body. A bearing seat is arranged in the bearing hole, and the bearing seat is detachably connected to the machine body. A rotating shaft is rotatably arranged on the bearing seat, and a vibrator is arranged on the rotating shaft. A synchronous pulley is arranged on one of the rotating shafts, and the synchronous pulley is used to be connected to a motor through a synchronous belt. The opposite ends of the rotating shaft are connected with couplings, and a telescopic rod is connected between the couplings. The telescopic rod includes a first connecting rod and a second connecting rod. The first connecting rod is connected to one of the couplings, and the second connecting rod is connected to the other coupling. A telescopic groove is opened on the end wall of the first connecting rod, and the second connecting rod is slidably arranged in the telescopic groove. A key block is integrally arranged on the second connecting rod, and a key groove is opened on the inner wall of the telescopic groove. The key block is slidably arranged in the key groove and is mutually adapted. A crossbeam protective cover is arranged between the machine bodies, and the bearing seat, the couplings and the telescopic rod are located in the crossbeam protective cover. Connectors are arranged between the two ends of the crossbeam protective cover and the machine body to achieve installation. The side wall of the bearing seat is detachably connected with a side protective cover.

[0006] By adopting the above technical solution, when the bearing housing inside the bearing hole needs to be maintained, first remove the side guard, then disassemble the bearing housing from the machine body. At this time, move the bearing housing away from the machine body. The second connecting rod can slide in the telescopic groove, and the telescopic rod extends. After moving the bearing housing away from the machine body, the bearing housing can be maintained, so that it is not necessary to enter the inside of the machine body to disassemble the cross beam guard to maintain the bearing housing. It only needs to remove the side guard outside the machine body. The cross beam guard can not only protect the bearing housing and the telescopic rod, but also serve as a cross beam to improve the overall strength of the machine body, thus saving the space inside the machine body; after the maintenance is completed, fix the bearing housing to the machine body, and then fix the side guard to the bearing housing. The second connecting rod is adaptively inserted into the telescopic groove. When the external motor drives the rotating shaft on one of the bearing housings to rotate, the key block abuts against the inner wall of the key groove, and drives the telescopic rod to rotate through the coupling, so as to realize the synchronous rotation vibration of the two rotating shafts.

[0007] Preferably, the connecting piece includes a connecting plate and connecting bolts. The connecting plate is integrally arranged on the end wall of the cross beam guard. A plurality of connecting bolts are arranged on the connecting plate. The connecting bolts penetrate through the connecting plate. A connecting hole for the connecting bolts to penetrate is formed in the side wall of the machine body. The connecting bolts are threadedly connected with the connecting holes, and the end of the connecting bolt abuts against the connecting plate.

[0008] By adopting the above technical solution, when installing the cross beam guard, pass the telescopic rod through the cross beam guard, arrange the cross beam guard between the machine bodies, make the connecting plate fit with the side wall of the machine body, then thread the connecting bolts through the connecting plate and the connecting holes, and use the end of the connecting bolt to abut against the connecting plate, so as to fix the cross beam guard between the machine bodies.

[0009] Preferably, a positioning hole for the connecting bolts to penetrate is formed in the bearing housing. The positioning hole is adapted to the connecting bolts. A nut is threadedly connected to the connecting bolts, and the nut abuts against the surface of the bearing housing.

[0010] Preferably, an installation plate is integrally arranged on the side guard. The installation plate fits with the side wall of the bearing housing. An installation hole for the connecting bolts to penetrate is formed in the installation plate. The installation plate is located between the nut and the bearing housing, and the nut abuts against the surface of the installation plate.

[0011] By adopting the above technical solution, when installing the bearing housing and the side guard, first pass the connecting bolts through the positioning holes, then pass the connecting bolts through the installation holes, rotate the nuts, and make the nuts abut against the surface of the installation plate. The nuts can be used to fix the bearing housing and the side guard on the machine body. When disassembling, rotate the nuts to separate from the connecting bolts, and then the side guard and the bearing housing can be disassembled from the machine body in sequence. The installation is convenient, and at the same time, there are few installation parts, which is beneficial to cost saving.

[0012] Preferably, an anti-slip sheet is arranged between the nut and the mounting plate, and the nut is in contact with the anti-slip sheet.

[0013] By adopting the above technical solution, the anti-slip sheet increases the friction between the nut and the mounting plate, and improves the stability of the nut after installation.

[0014] Preferably, a plurality of reinforcing blocks are fixedly arranged on the connecting plate and the side wall of the cross beam shield.

[0015] By adopting the above technical solution, the reinforcing blocks enhance the strength between the connecting plate and the cross beam shield, thereby improving the supporting effect of the cross beam shield.

[0016] Preferably, heat dissipation holes are formed in the side shield.

[0017] By adopting the above technical solution, it is beneficial to dissipate heat inside the side shield.

[0018] Preferably, an observation port is formed in the side wall of the side shield, and a transparent window is arranged in the observation port.

[0019] By adopting the above technical solution, it is convenient to observe the working condition of the bearing seat inside the side shield through the transparent window.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing a machine body, bearing holes, bearing seats, rotating shafts, vibrators, synchronous wheels, couplings, telescopic rods, key blocks, key grooves, cross beam shields, connecting members and side shields, first remove the side shield, and then disassemble the bearing seat from the machine body. At this time, operate the bearing seat away from the machine body. The second connecting rod can slide in the telescopic groove, and the telescopic rod extends. After moving the bearing seat away from the machine body, the bearing seat can be maintained, so that it is not necessary to enter the machine body to disassemble the cross beam shield to repair the bearing seat. Only the side shield needs to be disassembled outside the machine body, and the cross beam shield can not only protect the bearing seat and the telescopic rod, but also serve as a cross beam to improve the overall strength of the machine body, thereby saving the space inside the machine body; 2. By providing a connecting plate and connecting bolts, when installing the cross beam shield, pass the telescopic rod through the cross beam shield, arrange the cross beam shield between the machine bodies, make the connecting plate fit with the side wall of the machine body, and then thread the connecting bolts through the connecting plate and the connecting holes. Using the end of the connecting bolt to abut against the connecting plate, the cross beam shield can be fixed between the machine bodies; 3. By setting positioning holes and mounting holes, when installing the bearing seat and the side guard, first pass the connecting bolts through the positioning holes, then pass the connecting bolts through the mounting holes, rotate the nuts until the nuts abut against the surface of the mounting plate, and the bearing seat and the side guard can be fixed on the machine body by using the nuts. When disassembling, rotate the nuts to disengage from the connecting bolts, and then the side guard and the bearing seat can be disassembled from the machine body successively. The installation is convenient, and at the same time, there are few installation parts, which is beneficial to cost saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following Figures 1-3 further describes the present application in detail.

[0026] An embodiment of the present application discloses a vibration screen protection structure. Referring to Figures 1 to 3 , it includes a machine body 1 and bearing holes 11 symmetrically opened on the machine body 1. A bearing seat 2 is arranged in the bearing holes 11. The bearing seat 2 is detachably connected to the machine body 1. A rotating shaft 21 is rotatably arranged on the bearing seat 2, and the two rotating shafts 21 are coaxially arranged. A vibrator 22 is arranged on the rotating shaft 21. A synchronous pulley 23 is arranged on one of the rotating shafts 21. The synchronous pulley 23 is used to be connected to a motor through a synchronous belt, and an external motor drives one of the rotating shafts 21 to rotate through the synchronous belt.

[0027] Referring to Figure 2 and Figure 3, a coupling 3 is connected to the opposite ends of the rotating shaft 21, and a telescopic rod 4 is connected between the couplings 3. The length direction of the telescopic rod 4 is arranged along the width direction of the machine body 1. The telescopic rod 4 includes a first connecting rod 41 and a second connecting rod 42. The first connecting rod 41 is connected to one of the couplings 3, and the second connecting rod 42 is connected to the other coupling 3. A telescopic groove 411 is formed in the end wall of the first connecting rod 41 along its length direction. The second connecting rod 42 is slidably arranged in the telescopic groove 411. A key block 421 is integrally provided on the second connecting rod 42. A key groove 412 is formed in the inner wall of the telescopic groove 411. The key block 421 is slidably arranged in the key groove 412 and is mutually adapted. When one of the rotating shafts 21 drives the coupling 3 to rotate, the key block 421 abuts against the key groove 412, driving the telescopic rod 4 to rotate, thereby realizing the synchronous rotational vibration of the two rotating shafts 21.

[0028] Refer to Figures 1 to 3 , a crossbeam shield 5 is arranged between the machine bodies 1. The bearing seats 2, the couplings 3 and the telescopic rods 4 are located inside the crossbeam shield 5. Connecting members 6 are arranged between the two ends of the crossbeam shield 5 and the machine bodies 1. The side wall of the bearing seat 2 is detachably connected with a side shield 7. When it is necessary to maintain the bearing seat 2 in the bearing hole 11, first remove the side shield 7, and then disassemble the bearing seat 2 from the machine body 1. At this time, operate the bearing seat 2 away from the machine body 1. At this time, the second connecting rod 42 can slide in the telescopic groove 411, and the telescopic rod 4 extends. After moving the bearing seat 2 away from the machine body 1, the bearing seat 2 can be maintained, so that it is not necessary to enter the inside of the machine body 1 to disassemble the crossbeam shield 5 to maintain the bearing seat 2. It is only necessary to remove the side shield 7 outside the machine body 1. The crossbeam shield 5 can not only protect the bearing seat 2 and the telescopic rod 4, but also serve as a crossbeam to improve the overall strength of the machine body 1, thus saving the space inside the machine body 1. Refer to Figure 3 , the connecting member 6 includes a connecting plate 61 and a connecting bolt 62. The connecting plate 61 is integrally provided on the end wall of the crossbeam shield 5. The connecting plate 61 is arranged along the circumferential direction of the crossbeam shield 5. A plurality of reinforcing blocks 51 are fixedly arranged by welding between the connecting plate 61 and the side wall of the crossbeam shield 5. A plurality of connecting bolts 62 are arranged on the connecting plate 61. The connecting bolts 62 penetrate through the connecting plate 61. A connecting hole 12 for the connecting bolts 62 to penetrate through is formed in the side wall of the machine body 1. When installing the crossbeam shield 5, pass the telescopic rod 4 through the crossbeam shield 5, arrange the crossbeam shield 5 between the machine bodies 1, make the connecting plate 61 fit with the side wall of the machine body 1, and then thread the connecting bolts 62 through the connecting plate 61 and the connecting hole 12. Using the end of the connecting bolt 62 to abut against the connecting plate 61, the crossbeam shield 5 can be fixed between the machine bodies 1.

[0029] Refer to Figure 3The bearing seat 2 is provided with a positioning hole 24 for the connecting bolt 62 to pass through, and the positioning hole 24 and the connecting bolt 62 are adapted to each other. The side shield 7 is integrally provided with a mounting plate 71, and the mounting plate 71 is fitted with the side wall of the bearing seat 2. The mounting plate 71 is provided with a mounting hole 711 for the connecting bolt 62 to pass through, and the mounting hole 711 is flush with the positioning hole 24. The connecting bolt 62 is threadedly connected with a nut 8. When installing the bearing seat 2 and the side shield 7, the connecting bolt 62 is first passed through the positioning hole 24, and then the connecting bolt 62 is passed through the mounting hole 711, and the nut 8 is rotated to make the nut 8 abut against the surface of the mounting plate 71. The bearing seat 2 and the side shield 7 can be fixed on the body 1 by the nut 8. When disassembling, the nut 8 is rotated to separate from the connecting bolt 62, and the side shield 7 and the bearing seat 2 can be successively disassembled from the body 1. The installation is convenient, and there are fewer installation parts, which is conducive to cost saving. An anti-skid sheet 81 is provided between the nut 8 and the mounting plate 71 , and the nut 8 abuts against the anti-skid sheet 81 . The anti-skid sheet 81 increases the friction between the nut 8 and the mounting plate 71 , thereby improving the stability of the nut 8 after installation.

[0030] Reference Figure 3 The side shield 7 is provided with a heat dissipation hole 72, which is conducive to heat dissipation inside the side shield 7. The side wall of the side shield 7 is provided with an observation port 9, and a transparent window 91 is arranged in the observation port 9. The transparent window 91 is made of glass, and the working condition of the bearing seat 2 in the side shield 7 can be conveniently observed through the transparent window 91.

[0031] The implementation principle of a vibrating screen protection structure of an embodiment of the present application is as follows: when it is necessary to maintain the bearing seat 2 in the bearing hole 11, rotate the nut 8 to disengage the nut 8 from the connecting bolt 62. At this time, the side shield 7 can be removed first, and then the bearing seat 2 and the machine body 1 can be disassembled, and the bearing seat 2 is moved away from the machine body 1. The second connecting rod 42 can slide in the telescopic groove 411, and the telescopic rod 4 is extended. After the bearing seat 2 is moved away from the machine body 1, the bearing seat 2 can be maintained. Therefore, there is no need to enter the machine body 1 to disassemble the crossbeam shield 5 to repair the bearing seat 2. Only the side shield 7 needs to be disassembled outside the machine body 1. The crossbeam shield 5 can not only protect the bearing seat 2 and the telescopic rod 4, but also serve as a crossbeam to improve the overall strength of the machine body 1, thereby saving space inside the machine body 1. After the maintenance is completed, the connecting bolt 62 is passed through the positioning hole 24 and the mounting hole 711, and the nut 8 is turned to fix the side shield 7 and the bearing seat 2. At this time, the second connecting rod 42 is adapted to be inserted in the telescopic groove 411. When the external motor drives the rotating shaft 21 on one of the bearing seats 2 to rotate, the key block 421 abuts against the inner wall of the key groove 412, and drives the telescopic rod 4 to rotate through the coupling 3, thereby realizing the synchronous rotation and vibration of the two rotating shafts 21.

[0032] The above are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
