Technical Field
[0001] This application relates to the technical field of crushing equipment, and in particular to a crusher that is easy to maintain. Background Technology
[0002] A crusher is a crushing machine that crushes large pieces of material. When in use, large pieces of material are fed into the crusher through the feed inlet. At this time, the rotor in the crusher rotates and drives the material entering the crusher to move towards the underside of the rotor disc and rotate around the rotor disc, thereby continuously contacting the rotor disc and being crushed. When the crushed material fits into the screen holes on the screen plate on the lower side of the crusher, the crushed material passes through the screen plate and leaves the crusher. The material that has not been completely crushed continues to be crushed in the crusher until it is completely crushed.
[0003] During prolonged material crushing, the side of the rotor disc furthest from the feed inlet is prone to material jamming, requiring manual clearing of the jammed area. Chinese Patent CN207680700U discloses a feed inlet structure and an impact crusher. This feed inlet structure includes a frame with a feed inlet at the top. An adjusting component at the feed inlet adjusts its size. The frame houses a rotor section for crushing material entering through the feed inlet. When blockage occurs, the size of the feed portion of the inlet can be altered to resolve the blockage.
[0004] The instruction manual in conjunction with the relevant technology is attached. Figure 1 It is known that in the relevant technology, the tilting frame 101 can be driven to open around the shaft by the tilting cylinder 106. The joint between the tilting frame 101 and the lower frame 103 is set horizontally and located on the upper side of the shaft of the rotor 130. Therefore, when the crusher jams and the tilting frame 101 is opened, some material on the side of the rotor 130 away from the feed port is still difficult to clean, which will have an adverse effect on the cleaning efficiency. Utility Model Content
[0005] To reduce the adverse impact on cleaning efficiency, this application provides a crusher that is easy to maintain.
[0006] The crusher provided in this application, which is easy to maintain, adopts the following technical solution:
[0007] A crusher that is easy to maintain includes a shell body and a rotor shaft rotatably connected inside the shell body. A feed inlet is provided at one end of the upper side of the shell body, and a tilting shell is rotatably connected to the other end of the upper side of the shell body. The gap between the tilting shell and the lower side of the shell body is inclined downward towards the side away from the feed inlet and parallel to the diameter direction of the rotor shaft. A clearance hole adapted to the rotor shaft is provided on the lower side of the tilting shell. A rotating component is provided on the shell body to drive the tilting shell to rotate.
[0008] By adopting the above technical solution, the rotating component drives the flip shell to rotate and open. At this time, the side of the rotor shaft away from the feed inlet is located outside the shell body, which facilitates the material stuck on the side of the rotor shaft away from the feed inlet to fall off. When some material is still stuck on the side of the rotor shaft away from the feed inlet, the staff can clean up the stuck material, reducing the amount of material that the staff needs to clean and reducing the adverse impact on cleaning efficiency.
[0009] Optionally, the rotating component includes hydraulic cylinders disposed on both sides of the shell body, one end of the hydraulic cylinder being hinged to the lower side of the shell body and the other end being hinged to the flipping frame, and the rotating body being provided with a fixing component for fixing the relative position of the flipping shell and the shell body when they are closed.
[0010] By adopting the above technical solution, when the tilting shell is opened, the telescopic rod of the hydraulic cylinder extends and drives the tilting shell to rotate away from the shell body, which facilitates the opening of the tilting shell. When closing, the telescopic rod of the hydraulic cylinder retracts and drives the tilting shell to rotate and close the shell body. At this time, the tilting shell and the shell body are fixed by the fastener, which facilitates the opening or closing of the tilting shell and reduces the adverse impact on cleaning efficiency.
[0011] Optionally, the fastener includes a screw fixedly connected to the edge of the shell body near the rotor shaft, and a fixing plate corresponding to the screw is fixedly connected to the side of the flip shell near the rotor shaft. When the flip shell is closed with the shell body, the screw passes through the corresponding fixing plate and is fitted with a nut.
[0012] By adopting the above technical solution, when opening and cleaning the flip shell, the drive nut rotates and disengages from the screw. At this time, the flip shell and the shell body are released from fixation, making it easier to drive the flip shell to rotate. When driving the hydraulic cylinder to close the shell body, the screw passes through the corresponding fixing plate. At this time, the nut is rotated until it abuts against the fixing plate, which facilitates fixing the flip shell to the shell body, improves the stability of the flip shell closing the shell body, and further reduces the adverse effects on cleaning efficiency.
[0013] Optionally, a plurality of symmetrically arranged mounting plates are fixedly connected to the side of the shell body away from the feed inlet. The mounting plates pass through and are fixedly connected to the same rotating shaft parallel to the rotor shaft. The lower side of the flipping frame away from the feed inlet is fixedly connected to locking plates symmetrically arranged at both ends of the rotating shaft and rotatably connected to the rotating shaft. Each end of the rotating shaft is provided with a locking pin. When the flipping shell rotates and opens, the locking pin passes through the mounting plate and the locking plate located at the end of the rotating shaft at the same time.
[0014] By adopting the above technical solution, when the rotating shell is driven to rotate along the rotating shaft and open the shell body, the relative position of the rotating shell and the shell body is fixed by the locking pin passing through the mounting plate and locking plate at the end of the rotating shaft. This improves the stability of the rotating shell when it is opened, reduces the adverse impact on the safety of workers when cleaning up stuck materials, and also reduces the adverse impact on cleaning efficiency when the rotating shell closes under external force.
[0015] Optionally, guide components are provided on both sides of the shell body, located on the side of the shell body closer to the flip shell, and the flip shell is positioned and covers the shell body through the guide components.
[0016] By adopting the above technical solution, when the flip shell covers the shell body, the guide component guides the flip shell until the flip shell covers the shell body, reducing the possibility of displacement when the flip shell flips and covers the shell body, and improving the stability of the flip shell covering.
[0017] Optionally, the guiding assembly includes a first guide plate fixedly connected to the shell body. The upper side of the first guide plate is higher than the height of the gap between the shell body and the flip shell. A second guide plate corresponding to the first guide plate is fixedly connected to the lower side of the flip shell. Guide teeth are fixedly connected to the lower side of the second guide plate. The width of the guide teeth gradually decreases towards the first guide plate along the length direction of the shell body. A guide groove adapted to the guide teeth is formed on the first guide plate.
[0018] By adopting the above technical solution, during the process of the flip shell rotating and covering the shell body, the second guide plate rotates towards the corresponding first guide plate. At this time, the end with the smaller width of the guide tooth first inserts into the guide groove. The flip shell continues to rotate, and the side wall of the guide groove guides the flip shell through the guide tooth until the guide tooth is fully inserted into the corresponding guide groove. The flip shell completely covers the shell body, reducing the possibility of displacement when the flip shell flips and covers the shell body, and improving the stability of the flip shell covering.
[0019] Optionally, the guide teeth are configured in multiple ways, and the guide grooves correspond one-to-one with the guide teeth.
[0020] By adopting the above technical solution, when the flip shell rotates and covers the shell body, multiple guide teeth are positioned by the guide groove on the first guide plate, which further reduces the possibility of the flip shell deflecting during the process of covering the shell body and improves the stability of the flip shell covering.
[0021] Optionally, the gap between the upper end of the shell body and the flip shell near the flip shell is downward and inclined towards the flip shell.
[0022] By adopting the above technical solution, the gap between the upper end of the shell body and the flip shell is inclined, which makes it easier for the flip shell to be spliced with the shell body to form a whole without affecting the rotation of the flip shell, and further reduces the adverse impact on cleaning efficiency.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The rotating component drives the flip shell to rotate and open. At this time, the side of the rotor shaft away from the feed inlet is located outside the shell body, which facilitates the material stuck on the side of the rotor shaft away from the feed inlet to fall off. When some material is still stuck on the side of the rotor shaft away from the feed inlet, the staff can clean up the stuck material, reducing the amount of material that the staff needs to clean and reducing the adverse impact on cleaning efficiency.
[0025] 2. When the rotating shell is driven to rotate along the rotating shaft and open the shell body, the relative position of the rotating shell and the shell body is fixed by the locking pin passing through the mounting plate and locking plate at the end of the rotating shaft. This improves the stability of the rotating shell when it is opened, reduces the adverse impact on the safety of workers when cleaning up stuck materials, and also reduces the adverse impact on cleaning efficiency when the rotating shell closes under external force.
[0026] 3. During the process of the flip shell rotating and covering the shell body, the second guide plate rotates towards the corresponding first guide plate. At this time, the end with the smaller width of the guide tooth first inserts into the guide groove. The flip shell continues to rotate, and the side wall of the guide groove guides the flip shell through the guide tooth until the guide tooth is fully inserted into the corresponding guide groove. The flip shell completely covers the shell body, reducing the possibility of displacement when the flip shell flips and covers the shell body, and improving the stability of the flip shell covering.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a crusher that is easy to maintain. (Refer to...) Figure 1 and Figure 2 A crusher that is easy to maintain includes a vertical shell body 1. One end of the upper side of the shell body 1 is provided with a feed port 11 that communicates with the interior of the shell body 1. A horizontal rotor shaft 12 with both ends passing through the side wall of the shell body 1 is rotatably connected in the shell body 1. The rotor shaft 12 is arranged along the width direction of the shell body 1. Bearing seats 13 are installed on both sides of the shell body 1. The ends of the rotor shaft 12 are installed on the corresponding bearing seats 13.
[0032] A tilting shell 2 is provided on the upper side of the shell body 1 away from the feed inlet 11, which can be spliced with the shell body 1 to form an integral part. The gap between the upper part of the shell body 1 and the tilting shell 2 is downward and inclined towards the tilting shell 2. The gap between the lower part of the shell body 1 and the tilting shell 2 is downward and parallel to the diameter of the rotor shaft 12. Both sides of the tilting shell 2 are provided with relief holes 21 adapted to the rotor shaft 12. When the tilting shell 2 covers the shell body 1, the upper side of the rotor shaft 12 is located in the relief hole 21.
[0033] Reference Figure 1 and Figure 2 A vertical mounting plate 14, parallel to the length of the shell body 1, is fixedly connected to the middle of the lower side of the shell body 1, away from the feed inlet 11. A set of symmetrically arranged mounting plates 14 is provided on each side of the mounting plate 14. Each set of mounting plates 14 includes two plates, and the distance between the mounting plates 14 in the same set is less than the distance between the middle mounting plate 14 and its adjacent mounting plate 14. A horizontal rotating shaft 15 passes through and is mounted on each mounting plate 14.
[0034] Two symmetrically arranged limiting plates 22 are fixedly connected to the lower side of the flip shell 2 near the mounting plate 14. The limiting plates 22 are both sleeved on the rotating shaft 15 and rotatably connected to the rotating shaft 15. The shell body 1 is provided with a rotating component that drives the flip shell 2 to rotate along the rotating shaft 15 and a fixing component 3 that fixes the relative position of the flip shell 2 when it closes the shell body 1.
[0035] The rotating component drives the flip shell 2 to rotate and open. At this time, the side of the rotor shaft 12 away from the feed inlet 11 is located outside the shell body 1, which facilitates the material stuck on the side of the rotor shaft 12 away from the feed inlet 11 to fall off. When some material is still stuck on the side of the rotor shaft 12 away from the feed inlet 11, the staff can clean up the stuck material to reduce the amount of material that the staff needs to clean.
[0036] The gap between the upper end of the shell body 1 and the flip shell 2 is inclined, which makes it easy for the flip shell 2 to be spliced with the shell body 1 to form a whole without affecting the rotation of the flip shell 2.
[0037] The rotating component includes hydraulic cylinders 4 symmetrically arranged on both sides of the shell body 1 and hinged at one end to the lower side of the shell body 1. The hydraulic cylinders 4 are located on the side of the rotor shaft 12 away from the feed inlet 11. The extension rods of the hydraulic cylinders 4 are all inclined upward and away from the feed inlet 11 and hinged to the side wall of the flipping shell 2.
[0038] Reference Figure 1 and Figure 2 The fixing component 3 includes a stabilizing plate 31 fixedly connected to both sides of the shell body 1, located on the lower side of the shell body 1 and close to the rotor shaft 12. The stabilizing plate 31 is located on the side of the rotor shaft 12 close to the feed inlet 11 and parallel to the gap between the shell body 1 and the tilting shell 2. A screw 32 perpendicular to the stabilizing plate 31 is passed through and fixedly connected to the stabilizing plate 31. On both sides of the tilting shell 2 and on the side close to the stabilizing plate 31, there is a fixing plate 33 that corresponds to the stabilizing plate 31 and is parallel to the stabilizing plate 31. Each fixing plate 33 has a stabilizing hole (not shown in the figure) adapted to the screw 32. The screw 32 passes through the fixing hole 141 and is threaded with a nut 34.
[0039] Reference Figure 1 and Figure 2 Two symmetrical locking plates 23 are fixedly connected to one end of the flip shell 2 near the limiting plate 22, located on opposite sides of the limiting plate 22. Both locking plates 23 are sleeved and rotatably connected to the rotating shaft 15. The lower ends of the locking plates 23 are located on opposite sides of the same set of mounting plates 14. Each mounting plate 14 has a fixing hole 141 at its lower end, and the locking plates 23 located between the mounting plates 14 also have locking holes 231 on their lower sides. The rotating shaft 15 has a locking pin (not shown in the figure) at its end. When the flip shell 2 is fully opened, the horizontal projections of the locking holes 231 and the corresponding fixing holes 141 coincide, and the locking pins simultaneously pass through both the corresponding fixing holes 141 and the locking holes 231.
[0040] The drive nut 34 rotates and disengages from the screw 32. At this time, the flip shell 2 and the shell body 1 are released from fixation. The telescopic rod of the hydraulic cylinder 4 extends and drives the flip shell 2 to rotate away from the shell body 1 until the locking hole 231 coincides with the corresponding mounting hole in the horizontal direction. The relative position of the flip shell 2 and the shell body 1 when it is opened is fixed by the locking pin passing through the corresponding mounting plate 14 and the locking plate 23, thereby improving the stability of the flip shell 2 when it is opened.
[0041] When the cover is closed, the telescopic rod of the hydraulic cylinder 4 retracts and drives the flip shell 2 to rotate and cover the shell body 1 until the screw 32 passes through the stabilizing hole on the corresponding fixing plate 33. At this time, the nut 34 is rotated until the nut 34 abuts against the fixing plate 33, which facilitates the fixing of the flip shell 2 to the shell body 1 and improves the stability of the flip shell 2 covering the shell body 1.
[0042] Reference Figure 1 and Figure 2 Both sides of the shell body 1 are provided with guide components 5 to guide the rotation of the flip shell 2 and cover the shell body 1. The guide components 5 include a first guide plate 51 fixedly connected between the stabilizing plate 31 and the rotor shaft 12. The upper side of the first guide plate 51 is higher than the gap height between the lower side of the shell body 1 and the flip shell 2, and a second guide plate 52 corresponding to the first guide plate 51 is fixedly connected to the lower side of the flip shell 2.
[0043] The first guide plate 51 and the second guide plate 52 are both parallel to the gap between the lower side of the shell body 1 and the flip shell 2. The lower side of the second guide plate 52 is provided with a plurality of guide teeth 521 integrally formed with the second guide plate 52 and arranged along the length direction of the second guide plate 52. In this embodiment, two guide teeth 521 are provided, and the width of the guide teeth 521 gradually decreases towards the first guide plate 51 to form a pointed tip. The upper side of the first guide plate 51 is provided with guide grooves 511 that correspond one-to-one with the guide teeth 521. When the flip shell 2 is completely covered on the shell body 1, the guide teeth 521 are completely inserted into the corresponding guide grooves 511.
[0044] During the process of the flip shell 2 rotating and covering the shell body 1, the second guide plate 52 rotates towards the corresponding first guide plate 51. At this time, the tips of the guide teeth 521 are all inserted into the guide grooves 511. The flip shell 2 continues to rotate. At this time, the side wall of the guide groove 511 guides the flip shell 2 through the guide teeth 521 until the guide teeth 521 are fully inserted into the corresponding guide grooves 511. The flip shell 2 completely covers the shell body 1, reducing the possibility of displacement when the flip shell 2 flips and covers the shell body 1, and improving the stability of the flip shell 2 covering.
[0045] The implementation principle of a crusher that is easy to maintain according to an embodiment of this application is as follows: drive the tilting shell 2 to rotate and open. At this time, the side of the rotor shaft 12 away from the feed inlet 11 is located outside the shell body 1, which makes it easy for the material stuck on the side of the rotor shaft 12 away from the feed inlet 11 to fall off. When some material is still stuck on the side of the rotor shaft 12 away from the feed inlet 11, the staff can clean up the stuck material, reducing the amount of material that the staff needs to clean.
[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
