Description

Technical Field

[0001] The utility model belongs to the technical field of crushing machinery parts, and in particular relates to a combined protection device for the top bearing of a single-cylinder hydraulic cone crusher. Background Art

[0002] Single cylinder hydraulic cone crusher can be widely used in various ferrous, non-ferrous, non-metallic mines and sand and gravel industries. Its characteristics of large crushing force, high production efficiency, lamination crushing, and uniform finished product particle shape make single cylinder hydraulic cone crusher play an indispensable and important role in the crushing industry. Its principle is to drive the eccentric mechanism through a pair of meshing gears to drive the moving cone assembly to do eccentric swing motion, thereby squeezing and crushing the materials in the crushing chamber.

[0003] The single-cylinder hydraulic cone crusher includes a top bearing end cover. When the single-cylinder hydraulic cone crusher is used to crush some products or ores, the stone enters the machine from the feeding channel in the middle of the top bearing end cover. In the equipment in the prior art, since there is no protective device on the top bearing end cover, the falling of the stone will cause serious wear on the top of the top bearing end cover or the feeding channel. The service life is only 15 days, and the top bearing end cover needs to be replaced, and each installation and disassembly is relatively inconvenient; in addition, after the top bearing end cover is worn through, the stone enters the top bearing, causing damage to the top bearing, resulting in direct shutdown of the equipment, and a large workload for equipment maintenance.

[0004] To this end, the utility model designs a protective device for the top bearing end cover of a single-cylinder hydraulic cone crusher, in order to reduce the wear and damage to the top bearing end cover, improve the use efficiency of the equipment, and reduce the maintenance cost. Utility Model Content

[0052] The middle of the annular top cover 31 is a second material discharge port, and the first clamping strip 32 and the second clamping strip 33 are symmetrically arranged on two radial sides of the top cover 31. Specifically, in this embodiment, the first clamping strip 32 is arranged on the radial left front side of the top cover 31, and the second clamping strip 33 is arranged on the radial right rear side of the top cover 31, and the first clamping strip 32 and the second clamping strip 33 both extend downward in the vertical direction;

[0053] The upper end cover 21 is arranged at the top of the integrated snap-on component, and the upper end cover 21 and the integrated snap-on component are detachably connected. Furthermore, in the present embodiment, the upper end cover 21 and the integrated snap-on component are connected by bolts; the specific connection method is: a plurality of first threaded holes are provided on the upper end cover 21, and a plurality of second threaded holes are provided on the annular top cover 31 at positions corresponding to the first threaded holes of the upper end cover 21, and the bolts 23 pass through the first threaded holes and the second threaded holes in sequence to realize the bolt connection between the upper end cover 21 and the integrated snap-on component.

[0054] The top bearing end cover 41 is circular, and a feeding channel 42 for stone to pass through is provided in the middle of the top bearing end cover 41. The upper part of the feeding channel 42 protrudes a certain height from the top bearing end cover 41, and the middle of the feeding channel 42 is a third feeding port;

[0055] In this embodiment, the diameters of the first feeding opening, the second feeding opening and the third feeding opening are the same, and the positions of the first feeding opening, the second feeding opening and the third feeding opening in the vertical direction are correspondingly arranged;

[0056] The integrated snap-fit ​​component is arranged at the top end of the top bearing end cover 41, and the integrated snap-fit ​​component is detachably connected to the top bearing end cover 41. Specifically, the first snap-fit ​​strip 32 and the second snap-fit ​​strip 33 of the integrated snap-fit ​​component are arc-shaped on one side close to the second discharge port, and are adapted to the outer wall of the portion of the top bearing end cover 41 protruding from the discharge channel 42. The first snap-fit ​​strip 32 and the second snap-fit ​​strip 33 can be clamped on the outer wall of the portion of the top bearing end cover 41 protruding from the discharge channel 42, and the integrated snap-fit ​​component can be connected to the top end of the top bearing end cover 41 by clamping the first snap-fit ​​strip 32 and the second snap-fit ​​strip 33 with the portion of the top bearing end cover 41 protruding from the discharge channel.

[0057] The top bearing end cover 41 is a component of the single-cylinder hydraulic cone crusher, and is mainly arranged at the top of the top bearing frame in the single-cylinder hydraulic cone crusher. Specifically, the single-cylinder hydraulic cone crusher and the top bearing frame both adopt conventional equipment or components in the field, and are not the inventive point of the utility model, so they are not described in detail. At the same time, other structures not described in the top bearing end cover 41 in the utility model can adopt conventional settings in the field.

[0058] Further preferably, the end face of the top opening of the discharge channel 42 is also provided with a plurality of third threaded holes along the axial direction, and the positions of the plurality of third threaded holes correspond to the plurality of second threaded holes. By passing the bolts 23 through the first threaded holes, the second threaded holes and the third threaded holes in sequence, the bolt connection of the upper end cover 21, the integrated clip and the top bearing end cover 41 can be realized.

[0059] The truncated cone-shaped feed channel 11 described in the utility model is an upper end cover protection structure, and the integrated clip is a frame protection structure. The truncated cone-shaped feed channel 11 is fixed to the top of the top bearing end cover 41 by bolting the upper end cover 21 and the integrated clip.

[0060] Preferably, in this embodiment, the feed channel support 12 is a steel bar with an inverted trapezoidal structure and a thickness of not less than 10 mm, wherein one function of the feed channel support 12 is to top-connect and tighten the inner wall of the truncated cone-shaped feed channel 11, so that when the truncated cone-shaped feed channel 11 is embedded in the connecting channel 22, the lower part of the truncated cone-shaped feed channel 11 and the inner wall of the connecting channel 22 can be clamped, thereby fixing the relative positions of the truncated cone-shaped feed channel 11 and the connecting channel 22;

[0061] Another function is to form a barrier to large stones in the truncated cone-shaped feed channel 11. In the process of unloading stones, large stones are intercepted at the top of the feed channel support 12, thereby filling most of the space in the truncated cone-shaped feed channel 11. When smaller stones fall, a stone grinding situation can be formed, thereby protecting the top bearing end cover 41 and the frame below the top bearing end cover 41 from wear.

[0062] The truncated cone-shaped feed channel 11 and the feed channel support 12 in the present invention are both made of wear-resistant materials.

[0063] The height of the truncated cone-shaped feed channel 11 is not less than 200 mm, the diameter of the top opening is not less than 700 mm, and the diameter of the bottom opening is not less than 350 mm; the thickness of the truncated cone-shaped feed channel 11 is not less than 30 mm.

[0064] The hole diameters of the first threaded hole, the second threaded hole, and the third threaded hole are 22 mm.

[0065] Further preferably, a first lubricating oil pipe connecting hole 43 is further provided on the end surface of the top opening of the feeding channel 42 along the axial direction, and a second lubricating oil pipe connecting hole 34 is further provided on the annular top cover 31 at a position corresponding to the first lubricating oil pipe connecting hole 43;

[0066] The first lubricating oil pipe connecting hole 43 extends to the side wall of the feed channel 42 and opens from the side wall of the feed channel 42. At the same time, a rubber lubricating oil replenishing pipe 44 with a diameter of 8 mm is led out of the device from the bottom of the top bearing end cover 41 and connected to a lubricating oil replenisher. Lubricating oil can be replenished to the contact surface between the feed channel 42 and the annular top cover 31 and the contact surface between the upper end cover 21 and the annular top cover 31 through the lubricating oil replenisher, so as to facilitate the protection of the entire device and the lubrication between the components (especially the upper end cover 21 and the annular top cover 31).

[0067] Further preferably, a circular sealing groove may be provided at the top of the annular top cover 31, and a circular sealing protrusion may be provided at the bottom of the upper end cover 21. By embedding the sealing protrusion into the sealing groove, good contact between the upper end cover 21 and the circular top cover 31 and good sealing between the components can be achieved.

[0068] Before use, first insert the bottom end of the truncated cone-shaped feed channel 11 into the connecting channel from the opening at the top of the connecting channel 22, and then connect the first clamping strip 32 and the second clamping strip 33 with the protruding top bearing end cover 41 of the feed channel, connect the integrated clamping piece to the top of the top bearing end cover 41, and then place the upper end cover 21 on the top of the annular top cover 31, and make the positions of the first feed opening, the second feed opening and the third feed opening correspond, and make the positions of the first threaded holes, the second threaded holes and the third threaded holes correspond respectively, and pass the bolts 23 through the first threaded holes, the second threaded holes and the third threaded holes in sequence, and bolt the upper end cover 21, the integrated clamping piece and the top bearing end cover 41 together;

[0069] At this time, the positions of the second lubricating oil pipe connecting hole 34 and the first lubricating oil pipe connecting hole 43 correspond to each other. During use, lubricating oil can be added to the contact surface between the lower material channel 42 and the annular top cover 31 and the contact surface between the upper end cover 21 and the annular top cover 31 through the lubricating oil replenisher;

[0070] When in use, stones are placed into the truncated cone-shaped feed channel 11 from the top opening thereof, and the feed channel support 12 blocks large stones. In the process of lowering stones, large stones are intercepted at the top of the feed channel support 12, thereby filling up most of the space in the truncated cone-shaped feed channel 11. When smaller stones fall, a stone grinding situation is formed, thereby protecting the top bearing end cover 41 and the frame below the top bearing end cover 41 from wear.

[0071] The utility model can solve the problem in the prior art that, during the use of a single-cylinder hydraulic cone crusher, stones enter the top bearing after the top bearing end cover 41 is worn through, causing damage to the top bearing, wear of the end cover fixing screw holes and complete damage to the lower frame. At the same time, the added lubrication structure can also improve the lubrication effect between components, thereby reducing the equipment failure rate.

[0072] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
