Description

Technical Field

[0001] This utility model relates to the field of jaw crusher technology, specifically to a jaw crusher for sintered brick production. Background Technology

[0002] In the sintered brick production process, the crushing quality of the raw material pretreatment stage directly determines the subsequent brick forming effect and the quality of the finished bricks. As the core equipment for coarse / medium crushing of raw materials, the stable operation of the jaw crusher is crucial to the efficiency of the entire production line. The mainstream raw materials for sintered brick production (such as shale, coal gangue, and claystone) mostly originate from mining or industrial solid waste recycling. After mining or recycling, the raw materials often exhibit significant particle size unevenness, containing not only small and medium-sized pieces that meet the feeding requirements of the jaw crusher, but also a large number of oversized stones. If these directly enter the jaw crusher, it can easily cause problems such as material jamming and overload damage. Therefore, targeted screening of the stones entering the jaw crusher is a key preliminary step to ensure equipment operational stability and improve the quality of raw material pretreatment.

[0003] In the existing technology, the screening of jaw crushers mainly uses fixed grids to screen stones. However, after the stones are screened by the fixed grid, large stones will still accumulate on the surface of the fixed grid, affecting the subsequent screening efficiency of the fixed grid. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a jaw crusher for sintered brick production, which solves the technical problem that the screening efficiency of jaw crushers is easily affected by the accumulation of stones during the screening process of stones through a fixed grid in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a jaw crusher for sintered brick production, comprising a crusher body, a feed inlet provided on the top side wall of the crusher body, and further comprising a feed bin, a support frame, a screening frame, and a screening mechanism. The feed bin is fixedly disposed on the top side wall of the crusher body and communicates with the feed inlet. The support frame is fixedly disposed on the bottom side wall of the feed bin. The screening frame is fixedly disposed on the top side wall of the feed bin. The screening mechanism is disposed within the screening frame and is used to crush stones.

[0006] Preferably, the screening mechanism includes a screen plate, a fixed plate, and a stirring mechanism. The screen frame is provided with an arc-shaped screen plate. The fixed plate is fixedly disposed between the two ends of the screen plate and the inner wall of the screen frame. The stirring mechanism is disposed on the screen frame and is used to stir the stones on the screen plate.

[0007] Furthermore, the stirring mechanism includes a support cover, a support shell, a support column, stirring rods, a rotating mechanism, and a discharge mechanism. The support cover is fixedly installed on the side wall of the screening frame. A support opening is provided on the side wall of the screening frame, and the support opening communicates with the support cover. The support shell is slidably installed inside the support cover. The support column is rotatably installed on the side wall of the support shell. One end of the support column away from the support shell extends through the support opening into the screening frame. Multiple stirring rods are fixedly installed on the side wall of the support column. The rotating mechanism is installed on the support shell and is used to drive the support column to rotate. The discharge mechanism is installed on the support column and is used to discharge large stones after screening from the screening frame.

[0008] Furthermore, the rotating mechanism includes a first gear, a second gear, and a driving mechanism. The first gear is rotatably disposed within the support housing and is fixedly connected to the support column. The second gear is rotatably disposed within the support housing and meshes with the first gear. The driving mechanism is disposed on the support housing and is used to drive the second gear to rotate.

The first driving port is located on the support housing, the second driving port is located on the second gear, the driving prism is rotatably disposed between the inner wall of the support cover and the outer wall of the screening frame, the driving prism passes through the first driving port and the second driving port, and the driving prism is clearance-fitted to the inner wall of the second driving port. The first motor is mounted on the outer wall of the support cover, and the output end of the first motor is fixedly connected to the driving prism.

[0010] Based on the above scheme, the discharge mechanism includes a discharge port, a sealing disc, a pushing disc, and a moving mechanism. The discharge port is opened on one side of the screen plate on the side wall of the screening frame. The sealing disc is fixedly installed on the end of the support column away from the support cover and extends into the discharge port. The pushing disc is coaxial and fixedly installed on the support column. The moving mechanism is installed on the support housing and is used to drive the support housing and the support column to move.

[0011] Based on the above scheme, the moving mechanism includes a threaded rod and a second motor. The threaded rod is rotatably disposed between the inner wall of the support cover and the outer wall of the screening frame. The threaded rod passes through the support housing through a threaded engagement.

[0013] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, by setting up a screening mechanism, stones can be screened through a sieve plate. At the same time, during the screening process, the operation of the first motor can drive the drive prism to rotate, and then the gap between the drive prism and the inner wall of the second drive port can drive the second gear to rotate. Simultaneously, the meshing of the second gear and the first gear can drive the first gear and the support column to rotate, so that the stones can be stirred by the stirring rod on the support column, thereby improving the screening efficiency. 2. In this utility model, by setting up the discharge mechanism, after screening, the second motor can drive the threaded rod to rotate, and then the threaded rod and the support housing can move through the threaded engagement of the threaded rod and the support column. During the movement of the support column, the sealing plate can be discharged from the discharge port, and the large stones accumulated on the screen plate can be discharged from the discharge port through the pusher plate, thereby facilitating the cleaning of the large stones accumulated on the screen plate.
