Description

Technical Field

[0001] This utility model relates to the technical field of jaw crusher feeding equipment, specifically to a jaw crusher with a large inclination crushing chamber. Background Technology

[0002] A feeder is a device used to unload ore onto ore transport machinery, ore storage devices, or ore processing machinery (ore crushing). Commonly used feeders include plate feeders, trough feeders, chain feeders, swing feeders, disc feeders, belt feeders, drum feeders, electromagnetic vibrating feeders, and vibrating dischargers. Patent CN202222605622.X discloses an automatic feeding control structure for a jaw crusher. In this structure, two sets of hydraulic cylinders can drive a movable seat and a fixed seat to move via springs. Both the movable and fixed seats can drive the feed hopper to move via a fixed shaft, thus adjusting the height of the feed hopper. However, when using a large-angle feeder to feed the jaw crusher, the surface of the feed hopper is exposed. This causes dust mixed with the ore to be easily stirred up by the vibration of the feed hopper, and the stirred-up dust can easily fly around, causing some impact. Therefore, we propose a jaw crusher with a large inclination angle crushing chamber. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a jaw crusher with a large-angle crushing chamber.

[0004] The technical solution adopted by this utility model to solve its technical problem is a jaw crusher with a large inclination crushing chamber, including a frame bucket. The top surface of the frame bucket is bolted with a top plate for sealing, and the top surface of the top plate is bolted with a ring seat for support. There are two sets of ring seats. The ring seat is equipped with a ring frame for support, and a turbine fan for dust collection is installed on the inner side of the ring frame. The end of the ring seat located inside the frame bucket is bolted with a filter screen cover for protection.

[0005] A three-way pipe for guiding flow is assembled between the two sets of ring seats, and a ring seat for support is assembled at the open end of the three-way pipe away from the ring seat. A bracket for support is assembled inside the ring seat, and a fan body for guiding flow is assembled on the surface of the bracket. A ring body for support is screwed onto the end of the ring seat away from the three-way pipe, and a filter bag body for dust collection is assembled at the end of the ring body away from the ring seat.

[0006] By adopting the above technical solution, during the use of the jaw crusher's large-angle feeding equipment, the turbine fan on the ring frame in the ring seat on the top plate surface of the bucket can operate. The operation of the worm gear fan facilitates the extraction of dust raised when the ore passes through the bucket, making it easy to centrally process the dust. At the same time, the filter screen covers can protect the operation of the turbine fan, reducing the situation where the crushed stone splashes and hits the turbine fan, so that the turbine fan can stably extract the raised dust and make it easy to process.

[0007] When the turbine fan extracts dust, the dust is easily carried by the wind through the three-way pipe and into the ring seat. The fan body on the bracket inside the ring seat also operates, which facilitates the blowing of dust. This allows the dust to pass stably through the ring seat and into the filter bag body under the action of the wind, enabling the filter bag body to collect the dust. Air can easily pass through the mesh of the filter bag body. At the same time, the ring body and the ring seat are screwed together, which makes it easy to disassemble the filter bag body and clean the dust collected inside. This allows the fan body and the turbine fan to more stably extract the dust raised inside the frame hopper.

[0008] Specifically, a check valve is installed on the inner side of the ring seat.

[0009] By adopting the above technical solution, the check valve inside the ring can automatically open under the wind force of the fan body, which then facilitates the wind to carry dust through. When the wind force is reversed, the valve plate in the check valve will automatically close under the force of the reverse wind and its own torsion spring, thereby reducing the occurrence of dust backflow.

[0010] Specifically, both the top surface of the ring seat and the top surface of the ring seat are fitted with cover plates for maintenance by screws.

[0011] By adopting the above technical solution, the cover plate is easy to disassemble and assemble, and it is convenient to maintain the internal structure of the ring seat and the ring seat.

[0012] Specifically, the top surface of the frame is fitted with a protective outer shell, and a corrugated sleeve for protection is fitted between the outer shell and the top plate.

[0013] By adopting the above technical solution, the outer shell and the corrugated sleeve work together to protect the structure of the adjustable baffle inside the frame.

[0014] Specifically, the outer peripheral surface of the ring is provided with recessed holes, and there are multiple sets of recessed holes.

[0015] By adopting the above technical solution, the multiple sets of concave holes on the outer periphery of the ring make it easier to rotate the ring and disassemble it, thereby enabling the cleaning of dust in the filter bag.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of the top plate, ring seat, ring frame, turbine fan and filter screen, enables the turbine fan on the ring frame in the ring seat on the top plate surface of the jaw crusher to operate during the use of the jaw crusher's large-angle feeding equipment. The operation of the worm gear fan facilitates the extraction of dust raised when the ore passes through the jaw, making it easy to centrally process the dust. At the same time, the filter screen protects the turbine fan from operation, reducing the impact of flying gravel on the turbine fan, so that the turbine fan can stably extract the raised dust and facilitate its processing.

[0018] 2. The technical solution of this application, through the design of a three-way pipe, a ring seat, a bracket, a fan body, a ring body, and a filter bag body, allows dust to easily pass through the three-way pipe and enter the ring seat when the turbine fan is extracting dust. The fan body on the bracket inside the ring seat also operates, which facilitates the blowing of dust. This allows the dust to stably pass through the ring seat and enter the filter bag body under the action of the wind, enabling the filter bag body to collect the dust. Air can easily pass through the mesh of the filter bag body. At the same time, the ring body and the ring seat are screwed together, which facilitates the disassembly of the filter bag body and the cleaning of the dust collected inside. This allows the fan body and the turbine fan to more stably extract and process the dust raised inside the frame. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a jaw crusher with a large-angle crushing chamber, including a frame bucket 1. A top plate 2 for sealing is bolted to the top surface of the frame bucket 1, and a ring seat 3 for support is bolted to the top surface of the top plate 2. There are two sets of ring seats 3. A ring frame 4 for support is installed inside the ring seat 3, and a turbine fan 5 for dust collection is installed inside the ring frame 4. A filter screen cover 17 for protection is bolted to one end of the ring seat 3 located inside the frame bucket 1. A three-way pipe 6 for guiding flow is installed between the two sets of ring seats 3, and a ring seat 7 for support is installed at the open end of the three-way pipe 6 away from the ring seat 3. A bracket 8 for support is installed inside the ring seat 7, and a fan body 9 for guiding flow is installed on the surface of the bracket 8. A ring body 10 for support is screwed to the end of the ring seat 7 away from the three-way pipe 6, and a filter bag body 11 for dust collection is installed at the end of the ring body 10 away from the ring seat 7.

[0026] When using the jaw crusher's large-angle feeding equipment, the turbine fan 5 on the ring seat 3 on the surface of the top plate 2 of the frame bucket 1 can operate. The operation of the worm gear fan makes it easy to extract the dust raised when the ore passes through the frame bucket 1, which is convenient for the dust to be concentrated and treated. At the same time, the filter screen 17 can protect the operation of the turbine fan 5, which can reduce the situation of crushed stone flying and hitting the turbine fan 5, so that the turbine fan 5 can stably extract the raised dust and make it easy to treat.

[0027] When the turbine fan 5 extracts dust, the dust is easily carried by the wind through the three-way pipe 6 and into the ring seat 7. The fan body 9 on the bracket 8 inside the ring seat 7 also operates, which facilitates the blowing of dust. This allows the dust to pass stably through the ring seat 7 and into the filter bag body 11 under the action of the wind, so that the filter bag body 11 can collect the dust. Air can easily pass through the mesh of the filter bag body 11. At the same time, the ring body 10 and the ring seat 7 are screwed together, which makes it easy to disassemble the filter bag body 11 and clean the dust collected inside. This allows the fan body 9 and the turbine fan 5 to more stably extract the dust raised inside the frame hopper 1.

[0028] like Figure 3 As shown, a check valve 12 is installed inside the ring seat 7.

[0029] When in use, the check valve 12 inside the ring seat 7 can be automatically opened under the wind force of the fan body 9, which then facilitates the wind force to carry dust through. When the wind force is reversed, the valve plate in the check valve 12 will be automatically closed under the force of the reverse wind force and its own torsion spring, thereby reducing the occurrence of dust backflow.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, both the top surface of the ring seat 7 and the top surface of the ring seat 3 are fitted with a cover plate 14 for maintenance by screws.

[0031] During use, the cover plate 14 is easy to disassemble and assemble, facilitating the maintenance of the internal structure of the ring seat 7 and the ring seat 3.

[0032] like Figure 1 As shown, the top surface of the frame 1 is fitted with a protective outer shell 15, and a protective corrugated sleeve 16 is fitted between the outer shell 15 and the top plate 2.

[0033] In use, the outer shell 15 and the corrugated sleeve 16 work together to protect the structure of the adjustable baffle inside the frame 1.

[0034] like Figure 1 and Figure 3 As shown, the outer circumferential surface of the ring body 10 is provided with recessed holes 13, and there are multiple sets of recessed holes 13.

[0035] When in use, the multiple sets of recessed holes 13 on the outer periphery of the ring body 10 make it easier to rotate the ring body 10 and facilitate the disassembly of the ring body 10, thereby enabling the cleaning of dust in the filter bag body 11.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in suitable positions. During the use of the jaw crusher's large-angle feeding equipment, the turbine fan 5 on the ring seat 3 of the top plate 2 of the frame bucket 1 operates. The worm gear fan facilitates the extraction of dust raised when ore passes through the frame bucket 1, making it easy to centrally process the dust. Simultaneously, the filter screen 17 protects the turbine fan 5 from impact by flying ore, allowing the turbine fan 5 to stably extract and process the raised dust. Furthermore, when the turbine fan 5 extracts dust, the dust easily passes through the tee with the wind force. Pipe 6 enters the ring seat 7, and the fan body 9 on the bracket 8 inside the ring seat 7 also operates, which facilitates the blowing of dust. This allows the dust to pass stably through the ring seat 7 and into the filter bag body 11 under the action of wind, so that the filter bag body 11 can collect the dust. Air can easily pass through the mesh of the filter bag body 11. At the same time, the ring body 10 and the ring seat 7 are screwed together, which makes it easy to disassemble the filter bag body 11 and clean the dust collected inside. This allows the fan body 9 and the turbine fan 5 to more stably suck up the dust raised inside the frame bucket 1, so that the large-angle feeding equipment can more stably feed the jaw crusher, which is convenient for the jaw crusher to crush the ore.
