[0039] In the embodiment, the mill wall 101 is used to cooperate with a crushing wall to crush materials. The cleaning part 2 is arranged at the mill wall 101, and the cleaning part 2 realizes the function of automatic cleaning by high-pressure water spraying to the inner wall of the mill wall 101, so as to avoid the problem that the crushing efficiency is affected due to the attachment and accumulation of material residues. The upper rack 102 provides a supporting structure for mounting the mill wall 101.

[0040] To achieve the installation of the mill wall 101, referring to Figure 2 、 Figure 3 , the top edge of the mill wall 101 of the cone crusher 1 is provided with a top protruding edge 111, and the bottom edge is provided with a bottom protruding edge 112, and the mill wall 101 is fixedly arranged in the upper rack 102 of the cone crusher 1 through the top protruding edge 111 and the bottom protruding edge 112.

[0041] The cross section of the top protruding edge 111 of the mill wall 101 is L-shaped, and the top protruding edge 111 is integrally arranged at the top of the mill wall 101. The inner wall of the upper rack 102 is provided with a mounting groove corresponding to the top protruding edge 111 and the mill wall 101. The mill wall 101 is arranged in the mounting groove of the upper rack 102 through the top protruding edge 111. The inner side of the top protruding edge 111 is provided with a slanting opening 113. The top of the mounting groove of the inner wall of the upper rack 102 is integrally provided with a slanting flange 121 corresponding to the slanting opening 113. The inclination of the slanting flange 121 and the slanting opening 113 is consistent.

[0042] The bottom protruding edge 112 of the mill wall 101 is integrally arranged at the bottom of the mill wall 101. When the mill wall 101 is arranged in the mounting groove of the upper rack 102 through the top protruding edge 111, the bottom protruding edge 112 corresponds to the position of the bottom of the upper rack 102 and is compatible in specification.

[0043] In this embodiment, the top edge of the mill wall 101 is provided with a top protruding edge 111 with an L-shaped cross section, and the top protruding edge 111 is directly integrally formed at the top of the mill wall 101. The inner wall of the upper rack 102 is provided with a mounting groove corresponding to the top protruding edge 111 and the mill wall 101.

The inclination of the slanting opening 113 and the slanting flange 121 is consistent, which ensures the accurate positioning and close fit between the mill wall 101 and the upper rack 102, and prevents the top protruding edge 111 from being blocked when the ore is fed, and prevents the top protruding edge 111 of the mill wall 101 from being damaged by the falling ore.

[0045] The bottom edge of the mill wall 101 is provided with an integrally formed bottom protruding edge 112. When the mill wall 101 is correctly installed in the mounting groove of the upper rack 102 through the top protruding edge 111, the bottom protruding edge 112 should correspond to the position of the bottom of the upper rack 102 and be compatible in specification. Through the cooperation and fixation of the bottom protruding edge 112 and the top protruding edge 111, the stability of the overall structure of the mill wall 101 can be further enhanced.

[0046] To achieve the cleaning of the mill wall 101, referring to Figure 2 ,Figure 3 、 Figure 6 The cleaning part 2 comprises an outer ring pipe 201, a positioning pipe 202 and a sliding water outlet pipe 203. Water is supplied to the inside of the positioning pipe 202 and the sliding water outlet pipe 203 through the outer ring pipe 201. The sliding water outlet pipe 203 is controlled in extension and retraction at the mill wall 101 by water pressure, so as to control the water flow to be sprayed from the sliding water outlet pipe 203 to the inner wall of the mill wall 101, thereby cleaning the mill wall 101.

[0047] In the embodiment, the outer ring pipe 201 serves as the main inlet of the water supply system, and is responsible for delivering cleaning water to the positioning pipe 202 and the sliding water outlet pipe 203. The positioning pipe 202 is fixed and penetrates through the outer ring pipe 201, and plays a supporting and guiding role for the sliding water outlet pipe 203. The water flow is guided from the outer ring pipe 201 to the sliding water outlet pipe 203, and the sliding water outlet pipe 203 is provided with a sliding track and a fixed support.

[0048] The sliding water outlet pipe 203 can slide and extend along the positioning pipe 202, and the sliding and extending power is driven by water pressure. The water spraying end of the sliding water outlet pipe 203 faces the inner wall of the mill wall 101, and the cleaning of the inner wall of the mill wall 101 is realized by spraying water flow.

[0049] In addition, in actual implementation, the sliding water outlet pipe 203 is thickened at one end close to the mill wall 101, and the water outlet of the sliding water outlet pipe 203 is arranged downward or upward and downward at the inner side of the thickened end. The water outlet of the sliding water outlet pipe 203 is a long strip-shaped water outlet, and the sprayed water flow is a fan-shaped water flow.

[0050] In order to realize the installation and displacement of the sliding water outlet pipe 203, the positioning pipe 202 is fixed and penetrates and is embedded at the side wall of the upper rack 102. One end of the positioning pipe 202 inside the upper rack 102 is sealingly and slidingly embedded with the sliding water outlet pipe 203, and the other end of the sliding water outlet pipe 203 can be penetratingly and sealingly slidingly embedded on the side wall of the mill wall 101. Figure 2 、 Figure 3 、 Figure 6

[0051] The sliding water outlet pipe 203 is further provided with a stopper block 231. When the stopper block 231 abuts against the end of the positioning pipe 202 inside the upper rack 102, the end of the sliding water outlet pipe 203 sealingly and slidingly embedded on the mill wall 101 is in the same plane with the inner wall of the mill wall 101.

[0052] ​In the embodiment, the positioning pipe 202 is fixedly installed in the side wall of the upper rack 102 and is arranged in a penetrating manner. The outer ring pipe 201 and the sliding water outlet pipe 203 are connected through the positioning pipe 202 to form a passage. Meanwhile, the positioning pipe 202 provides a guide channel for the sliding water outlet pipe 203 and ensures that the sliding water outlet pipe 203 keeps a stable direction during movement. One end of the positioning pipe 202 is located inside the upper rack 102, and the other end is connected to an external water supply system (the outer ring pipe 201).

[0053] The sliding water outlet pipe 203 is sealingly and slidingly arranged in the positioning pipe 202 and can slide in the positioning pipe 202 in an axial direction. The front end of the sliding water outlet pipe 203 is further arranged in a penetrating manner in the side wall of the mill wall 101, and the water outlet of the sliding water outlet pipe 203 extends to the inner wall surface of the mill wall 101.

[0054] The sliding water outlet pipe 203 can be extended and retracted under the action of water pressure. The outer portion of the sliding water outlet pipe 203 is provided with a stopper bump 231 for limiting the maximum extension position of the sliding water outlet pipe 203. Meanwhile, the stopper bump 231 supports the sliding water outlet pipe 203 when the sliding water outlet pipe 203 receives an axial pressure to prevent the sliding water outlet pipe 203 from being excessively retracted under the pressure.

[0055] In use, the sliding water outlet pipe 203 is not pushed by water pressure and is in a retracted state. The front end is located in the same plane as the inner wall of the mill wall 101. When water is supplied to the outer ring pipe 201, the water enters the positioning pipe 202. Since the water outlet of the sliding water outlet pipe 203 is in a closed state (the water outlet of the sliding water outlet pipe 203 is located at the mill wall) at this time, the water pressure pushes the sliding water outlet pipe 203 to slide forward along the positioning pipe. The stopper bump 231 moves together with the sliding water outlet pipe until the stopper bump 231 contacts the end portion of the positioning pipe 202 and stops moving forward. At this time, the water outlet of the sliding water outlet pipe 203 is located at the inner wall of the mill wall 101. The water is sprayed from the water outlet of the sliding water outlet pipe 203 and directly impacts the residual material on the inner wall of the mill wall 101. After the cleaning is completed, the water source is closed, the water pressure is reduced, and the sliding water outlet pipe 203 is manually pressed back to the initial position (i.e., the end portion of the sliding water outlet pipe 203 is in the same plane as the inner wall of the mill wall 101) to restore the cleaning part to a non-interference state and not affect the normal operation of the cone crusher.

[0056] In order to facilitate water supply to the positioning pipe 202 and the sliding water outlet pipe 203, the outer ring pipe 201 is a ring-shaped pipe with a water inlet 211 and a water outlet. Figure 1 、 Figure 2 The embodiment is the same as the above-described embodiment, and the same parts will not be described again. The difference is that: The embodiment is the same as the above-described embodiment, and the same parts will not be described again. The difference is that:

[0057] The embodiment is the same as the above-described embodiment, and the same parts will not be described again.

The end of each sliding water outlet pipe 203 located outside the side wall of the upper rack 102 is connected with the water outlet of the outer ring pipe 201.

[0058] In the embodiment, a plurality of cleaning parts are arranged on the circumference of the cone crusher to realize omnibearing cleaning of the inner wall of the rolling mill wall, avoid cleaning dead angle, improve cleaning efficiency and enhance cleaning effect.

[0059] Meanwhile, the reset spring 204 is arranged to push the sliding water outlet pipe 203 to automatically retract to the initial position by the force of the reset spring 204 after stopping water supply, so as to realize non-electric cleaning and automatic reset. Embodiment

By using the oil injection pressure plate 311 in cooperation with the outer driving sleeve 312, the rotation of the outer driving sleeve 312 controls the lifting of the oil injection pressure plate 311, thereby realizing the oil injection operation on the inner sleeve 141 of the joint bearing 104.

[0065] For the convenience of oil injection of the oil injection part 3, referring to Figure 4 , the oil injection channel 142 on the inner sleeve 141 of the joint bearing 104 includes a main channel 143 and a branch channel 144. The oil inlet of the oil injection channel 142 is located at the top of the inner sleeve 141 of the joint bearing 104. The main channel 143 is communicated with the branch channel 144. The oil outlet of the branch channel 144 is located on the outer sidewall of the inner sleeve 141. The main channel 143 and the branch channel 144 are both provided with multiple channels.

The cap 131 is detachably and sealingly arranged on the top of the top end head 103, the outer driving sleeve 312 is rotatably arranged on the cap 131 and is threadedly connected with the oil injection pressing plate 311, the lifting of the oil injection pressing plate 311 is controlled by rotating the outer driving sleeve 312.

[0070] The oil injection pressing plate 311 is a groove-shaped plate with a cavity at the bottom, the diameter of the oil injection pressing plate 311 is adapted to the inner shaft sleeve 141 of the joint bearing 104, when the cavity of the oil injection pressing plate 311 abuts against the inner shaft sleeve 141 of the joint bearing 104, the oil inlet of the oil injection channel 142 on the inner shaft sleeve 141 of the joint bearing 104 is located in the cavity of the oil injection pressing plate 311.

[0071] Meanwhile, the middle part of the oil injection pressing plate 311 is threadedly connected with the outer driving sleeve 312 through the integrally arranged threaded sleeve 314, the outer driving sleeve 312 is axially provided with a limiting long hole 315, and the top end of the outer driving sleeve 312 is provided with a fixing block 316 for facilitating the rotation of a wrench.

[0072] In this embodiment, the fixing block 316 at the top of the outer driving sleeve 312 is rotated by using a wrench, since the outer driving sleeve 312 is threadedly connected with the oil injection pressing plate 311, the rotation will push the oil injection pressing plate 311 to move downward. Under the guidance of the limiting ribs 132 and the limiting grooves 313, the oil injection pressing plate 311 keeps stable vertical movement. When the oil injection pressing plate 311 moves downward, the lubricating grease in the bottom cavity of the oil injection pressing plate 311 is injected into the joint bearing 104 through the oil injection channel 142, thereby completing one-time oil injection. Embodiment

[0073] The same parts as the above embodiment and its combination will not be described again, and the difference is that: In order to realize the emergency oil injection after the oil injection pressing plate 311 of the one-time oil injection unit 301 abuts against the inner shaft sleeve 141 of the joint bearing 104, the lubricating grease in the bottom cavity of the oil injection pressing plate 311 of the one-time oil injection unit 301 is squeezed out, see Figure 4 、 Figure 5The oil injection part 3 further comprises a secondary oil injection unit 302, the primary oil injection unit 301 is arranged at the top end head 103 and the cap 131, and the secondary oil injection unit 302 is arranged on the primary oil injection unit 301. When the primary oil injection unit 301 completes the oil injection of the oil injection channel 142, the secondary oil injection unit 302 is used for emergency oil injection.

[0074] The secondary oil injection unit 302 is arranged on the primary oil injection unit 301, and provides additional lubrication protection when necessary as an emergency oil injection mechanism. When the primary oil injection unit 301 completes the oil injection of the oil injection channel 142, if it is found that further supplement of lubricating grease is needed, the secondary oil injection unit 302 can be used for emergency oil injection.

[0075] Specifically, the secondary oil injection unit 302 comprises an oil injection inner push plate 321 and an inner driving rod 322. The oil injection inner push plate 321 is slidingly arranged in a cavity at the bottom of the oil injection pressure plate 311. A sliding hole 323 is formed in the middle of the oil injection inner push plate 321 corresponding to the threaded sleeve 314 of the oil injection pressure plate 311. The oil injection inner push plate 321 is sleeved on the threaded sleeve 314 of the oil injection pressure plate 311 through the sliding hole 323 in the middle of the oil injection inner push plate 321.

[0076] A sliding carriage 324 is arranged around the sliding hole 323 of the oil injection inner push plate 321. A conformal hole corresponding to the sliding carriage 324 is formed in the oil injection pressure plate 311. The sliding carriage 324 slides through the conformal hole and penetrates the oil injection pressure plate 311, and a bearing sleeve 325 is arranged at the top of the sliding carriage 324.

[0077] A sliding sleeve 326 is connected to the inside of the bearing sleeve 325 through a bearing. The sliding sleeve 326 is slidingly arranged at the limiting long hole 315 of the outer driving sleeve 312 and slides along the outer driving sleeve 312 in the axial direction through the limiting long hole 315. The inner driving rod 322 is rotatably arranged in the inner part of the outer driving sleeve 312, and is threadedly connected to the sliding sleeve 326.

[0078] In this embodiment, the oil injection inner push plate 321 is slidingly arranged in the cavity at the bottom of the oil injection pressure plate 311. Meanwhile, the sliding hole 323 is formed in the middle of the oil injection inner push plate 321 and is sleeved on the threaded sleeve 314 of the oil injection pressure plate 311.

[0079] The sliding carriage 324 is arranged around the sliding hole 323 at the top of the oil injection inner push plate 321, which provides structural support and transmits motion power. The bearing sleeve 325 is fixed to the top of the sliding carriage 324, and the sliding sleeve 326 is connected to the inside of the bearing sleeve 325 through a bearing, which ensures that the sliding sleeve 326 slides in the limiting long hole 315 of the outer driving sleeve 312 while being rotatable relative to the sliding sleeve 326.

[0080] The sliding sleeve 326 is slidingly arranged in the limiting long hole 315 of the outer driving sleeve 312, can slide axially along the outer driving sleeve 312, drives the oil injection inner push plate 321 to be pressed down, and simultaneously, through the threaded connection with the inner driving rod 322, the inner driving rod 322 drives the sliding sleeve 326 to move up and down when rotating.

[0081] The inner driving rod 322 is rotationally arranged inside the outer driving sleeve 312, is connected with the sliding sleeve 326 through a bearing, and is screwed with the sliding sleeve 326, is driven to move down the sliding sleeve 326 through rotation.

[0082] In use, when the oil injection pressure plate 311 of the primary oil injection unit 301 abuts against the inner shaft sleeve 141 of the joint bearing 104, the secondary oil injection unit is started, the inner driving rod 322 is rotated, the inner driving rod 322 drives the sliding sleeve 326 to move down along the limiting long hole 315 through screwing, the sliding sleeve 326 drives the sliding carriage 324 and the oil injection inner push plate 321 to be pressed down together, the oil injection inner push plate 321 compresses the lubricating grease in the chamber of the oil injection pressure plate 311, so that the lubricating grease is injected into the joint bearing 104 through the oil injection channel 142, after the oil injection is completed, the inner driving rod 322 is reversely rotated, the inner driving rod 322 drives the sliding carriage 324 and the oil injection inner push plate 321 to be reset upward, and finally the outer driving sleeve 312 is rotated, so that the outer driving sleeve 312 is separated from the abutting state with the inner shaft sleeve 141 of the joint bearing 104, thereby completing the whole lubricating grease injection process, and the cone crusher can be operated again.

[0083] It should be noted that in actual use, the bottom edge of the oil injection pressure plate 311 can be additionally provided with a rubber sleeve, when the main shaft of the cone crusher is operated by swinging through the joint bearing 104, when the bottom edge of the oil injection pressure plate 311 abuts against the inner shaft sleeve 141 of the joint bearing 104, the bottom edge of the oil injection pressure plate 311 abuts against the top of the inner shaft sleeve 141 of the joint bearing through the rubber strip, thereby facilitating the lubricating grease injection to the inner shaft sleeve.

[0084] In addition, even if the bottom edge of the oil injection pressure plate 311 does not completely close the top edge of the inner shaft sleeve 141 of the joint bearing 104, it can also form a closed state at the connection between the joint bearing 104 and the upper rack 102 through the closing effect of the top end closure, thereby ensuring the smooth injection of the lubricating grease.

[0085] Meanwhile, it should be noted that, in the embodiment, since the outer driving sleeve 312 is rotatably arranged at the cap 131 of the top end head 103 by a bearing, and the inner driving rod 322 is arranged inside the outer driving sleeve 312 by a bearing, the bearing cannot form a complete seal between the outer driving sleeve 312 and the cap 131 of the top end head 103, and the inner driving rod 322 cannot form a complete seal between the bearing and the outer driving sleeve 312, so a clamping type wear-resistant sealing cover can be additionally arranged at the cap 131 on the top of the outer driving sleeve 312, and the cap 131, the outer driving sleeve 312 and the inner driving rod 322 are sealed by the sealing cover, so as to prevent dust and impurities from entering the inside of the top end head 103, and the outer driving sleeve 312 and the inner driving rod 322 are protected, and the structure is prevented from being damaged by falling ore. Since the clamping type wear-resistant sealing cover is prior art, no more details are given here.

[0086] The top end of the inner driving rod 322 is shaped to be suitable for being twisted by a wrench, and the bottom end of the outer driving sleeve 312 is internally provided with a sealing sleeve 327, and the bottom end of the inner driving rod 322 is slidably penetrated through the sealing sleeve 327. The sealing sleeve 327 prevents lubricating grease from overflowing from the middle part of the outer driving sleeve 312 under the action of pressure, and ensures smooth injection of the lubricating grease.

[0087] Working principle of the conical crusher with self-cleaning function: In use, the conical crusher 1 crushes materials by the cooperation of the mill wall 101 and the crushing wall during the operation.

[0088] When the equipment needs to be cleaned, an external water source supplies water to the inside of the positioning pipe 202 and the sliding water outlet pipe 203 through the outer ring pipe 201, and the water pressure pushes the sliding water outlet pipe 203 to slide along the positioning pipe 202 to the inner wall of the mill wall 101 until the end of the sliding water outlet pipe 203 penetrates through the inner wall of the mill wall 101 and exposes the water outlet, at this time, water flows out from the long strip-shaped water outlet of the sliding water outlet pipe 203, forming a fan-shaped water flow, directly washing the residual materials on the inner wall of the mill wall 101, and completing the cleaning. After cleaning, the water supply is closed, and the sliding water outlet pipe 203 is automatically retracted to the initial position under the action of the reset spring 204, the end is flush with the inner wall of the mill wall 101, and the equipment returns to the crushing operation state.

[0089] When the conical crusher 1 needs to inject lubricating grease into the knuckle bearing 104, the operator simultaneously rotates the outer driving sleeve 312 of the primary oil injection unit 301 and the inner driving rod 322 of the secondary oil injection unit 302, and drives the oil injection pressure plate 311 and the oil injection inner push plate 321 to move downward synchronously, so as to inject lubricating grease into the knuckle bearing 104.

[0090] When the bottom cavity of the oil injection pressure plate 311 is in contact with the top of the inner sleeve 141 of the joint bearing 104, and the operator rotates the outer drive sleeve 312 and the inner drive rod 322 at the same time, the inner sleeve 141 is in abutment with the bottom of the oil injection pressure plate 311, and the rotation of the outer drive sleeve 312 and the inner drive rod 322 cannot be rotated, which can remind the operator that the remaining lubricating grease in the oil injection part 3 is not much, only the lubricating grease in the bottom cavity of the oil injection pressure plate 311, and remind him to disassemble the cap 131 and the oil injection part 3 as soon as possible, and add lubricating grease in the top end head 103.

[0091] When the oil injection part 3 only remains the lubricating grease in the bottom cavity of the oil injection pressure plate 311, the inner drive rod 322 of the secondary oil injection unit 302 drives the sliding sleeve 326 to move downward along the limiting long hole 315 through threaded transmission, drives the oil injection inner push plate 321 to compress the remaining lubricating grease in the cavity, and injects the joint bearing 104 again through the oil injection channel 142. After the oil injection is completed, the inner drive rod 322 is rotated in the opposite direction to drive the oil injection inner push plate 321 to reset, and the outer drive sleeve 312 is rotated to make the oil injection pressure plate 311 disengage from the inner sleeve 141 (to prevent the oil injection pressure plate 311 from abutting against the inner sleeve 141 to prevent interference with the swing operation of the main shaft of the cone crusher 1 through the joint bearing 104), that is, the entire oil injection process is completed, and the normal operation of the equipment is restored.
