Description

Technical Field

[0001] This utility model relates to the field of jaw crusher technology, and in particular to a jaw crusher with a rapidly adjustable discharge opening. Background Technology

[0002] Jaw crushers are a common type of crushing equipment. They are mainly composed of fixed jaw plates, movable jaw plates, eccentric shafts, flywheels, and toggle plates. The motor drives the eccentric shaft to rotate via a pulley, causing the movable jaw plates to reciprocate periodically. When the movable jaw plate approaches the fixed jaw plate, the material is crushed by forces such as compression, splitting, and bending between the two jaw plates. When the movable jaw plate moves away from the fixed jaw plate, the crushed material is discharged from the discharge port under the action of gravity.

[0003] In existing jaw crushers, adjusting the discharge opening size mostly involves changing the position of the moving jaw plate. This allows the moving jaw plate to move closer to the fixed jaw plate under the influence of a hydraulic system, shims, or wedges, thereby changing the discharge opening between the moving and fixed jaw plates. However, adjusting the shims and wedges is time-consuming, and the hydraulic system has a certain failure rate, which may lead to malfunction in the discharge opening adjustment and affect production. Therefore, we propose a jaw crusher that allows for rapid adjustment of the discharge opening. Utility Model Content

[0004] The main objective of this invention is to provide a jaw crusher with a rapidly adjustable discharge opening. By setting a feeding mechanism between the crusher body and the fixed jaw plate, the feeding mechanism, through a feeding and pushing structure composed of a hydraulic cylinder, a pushing cylinder, a bridge plate, and a pushing cylinder, can quickly push the fixed jaw plate closer to or further away from the moving jaw plate, thereby achieving rapid adjustment of the discharge opening size. It can also be adjusted to multiple preset positions as needed, improving the efficiency and flexibility of the jaw crusher's discharge opening adjustment and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A jaw crusher with a rapidly adjustable discharge opening includes a crusher body and a fixed jaw plate. The fixed jaw plate is fitted into the inner wall of the crusher body. The crusher body also includes a feeding mechanism, which comprises an inner guide seat, a main guide cylinder, a U-shaped outer fixed seat, an outer guide tube, a hydraulic cylinder, a pusher cylinder, a bridge plate, a pusher cylinder, and a fixed pin. Four guide grooves are formed on one side of the crusher body surface of the fixed jaw plate, and an inner guide seat is fitted into each guide groove. The inner baffle of the inner guide seat is bolted to the back of the fixed jaw plate. A through-hole for fitting the main guide seat is formed on the surface of the crusher body between the four corner grooves. The guide hole of the guide cylinder, the inner wall of the main guide cylinder is locked to the back plate of the fixed jaw plate by bolts, and a U-shaped outer fixed seat is welded to the surface of the crusher body below the guide hole. An outer guide tube for clamping the push cylinder is welded to the outer seat groove of the U-shaped outer fixed seat, and the housing of the hydraulic cylinder is locked to the outside of the outer guide tube by bolts.

The inner baffle plate of the seat body is installed and welded in the groove of the U-shaped seat plate of the inner guide seat.

[0010] By adopting the above technical solution, the inner guide seat can be installed in the four corner grooves of the fixed jaw plate, and then the inner guide seat can be firmly locked to the back of the fixed jaw plate with the inner baffle of the seat body and bolts.

[0011] Furthermore, mounting holes are provided at three points between the bottom of the main guide cylinder and the fixed jaw plate, and bolts are screwed between the mounting holes of the main guide cylinder and the fixed jaw plate.

[0012] By adopting the above technical solution, the three sets of mounting holes of the main cylinder and the fixed jaw plate can be screwed with bolts, so that the main cylinder and the fixed jaw plate are firmly connected.

[0013] Furthermore, a fixed welding groove is provided on the surface of the crusher body below the guide hole for welding the protrusion connecting plate, and the protrusion connecting plate is symmetrically fixed on the body of the U-shaped outer fixed seat.

[0014] By adopting the above technical solution, after the U-shaped outer fixed seat is welded and fixed to the protrusion connecting plate, the protrusion connecting plate can be clamped into the fixed welding groove of the crusher body for firm welding.

[0015] Furthermore, a semi-circular groove is provided on the surface of the vertical plate of the U-shaped outer fixed seat, and an outer guide tube is inserted and welded into the semi-circular groove of the U-shaped outer fixed seat near the hydraulic cylinder.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model sets up a feeding mechanism between the crusher body and the fixed jaw plate. The feeding mechanism, through a feeding and pushing structure composed of a hydraulic cylinder, a pushing cylinder, a bridge plate, and a pushing cylinder, can quickly push the fixed jaw plate closer to or away from the moving jaw plate, thereby realizing the rapid adjustment of the discharge port size. It can also be adjusted to multiple preset positions as needed, improving the adjustment efficiency and flexibility of the jaw crusher discharge port.

[0019] Furthermore, the four sets of seats on the back of the fixed jaw plate, along with the four sets of guide grooves on the surface of the crusher body, provide auxiliary guidance and support, so that the thrust structure of the fixed jaw plate does not need to bear a large support force, thus ensuring the stable pushing of the fixed jaw plate.
