Description

Technical Field

[0001] The utility model relates to the technical field of crushing machinery, in particular to an auxiliary dredging device for a jaw crusher. Background Art

[0002] In production operations, in order to improve the working efficiency of the jaw crusher, sometimes the method of increasing the amount of stone input is adopted, but this operation will cause some materials to fail to be crushed in time. When too much stone that is not fully crushed accumulates, it will cause the jaw crusher to get stuck inside, affecting the normal operation of the equipment;

[0003] In the prior art, a common method for dealing with stuck materials inside a jaw crusher is to use a crane to lift large stones out of the crushing bucket. This method is highly dependent on the crane, and during operation, due to the irregular shape of the stones, they are easy to fall off when lifted, which not only affects work efficiency but also has a high safety hazard. Therefore, the present application provides a jaw crusher auxiliary dredging device. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a jaw crusher auxiliary dredging device, which can be inserted into the crushing chamber of the jaw crusher from the lower side, and push the irregularly shaped stones stuck inside the jaw crusher so that they can be smoothly discharged from the jaw crusher, thereby reducing the total amount of stones inside the jaw crusher and reducing the load pressure of the jaw crusher so that it can resume operation.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Provided is a jaw crusher auxiliary dredging device, comprising a plurality of dredging top arms arranged at the lower side of a movable jaw plate; the movable jaw plate is detachably fixedly mounted on a movable jaw body, and the movable jaw body is rotatably connected to a frame of the jaw crusher through an eccentric shaft;

[0007] Multiple dredging top arms are connected to the second slide through separate sleeves respectively. The second slide is horizontally slidably installed on the first slide. The first slide is vertically slidably installed in the movable jaw body. A bin is provided at the bottom of the movable jaw body for accommodating multiple dredging top arms.

[0008] Furthermore, a plurality of crushing tooth grooves are arranged on the movable jaw plate, and the dredging top arm can be slidably engaged with the crushing tooth grooves.

[0009] Furthermore, a first telescopic driver for driving the first slide to move is installed on the movable jaw body, and a second telescopic driver for driving the second slide to move is installed on the first slide.

[0010] Furthermore, the upper and lower ends of the dredging top arm are respectively provided with pushing inclined surfaces.

[0011] Furthermore, an extrusion surface is provided in the middle of one side of the dredging top arm.

[0012] An optional technical solution for the connection between the dredging top arm and the sleeve in the present application is that the dredging top arm is fixedly installed in the sleeve.

[0013] Another optional technical solution for the connection between the dredging top arm and the sleeve in the present application is that the dredging top arm is slidably installed in the sleeve, and a spring is fixedly installed between the dredging top arm and the sleeve.

[0014] Furthermore, the first telescopic drive and the second telescopic drive both use heavy-duty hydraulic cylinders.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The auxiliary dredging device for a jaw crusher of the utility model controls the first slide to move on the movable jaw body and the second slide to move on the first slide, and controls the dredging top arm to push the irregularly shaped stones stuck inside the jaw crusher so that they can be smoothly discharged from the inside of the jaw crusher, thereby reducing the total amount of stones inside the jaw crusher and reducing the load pressure of the jaw crusher so that it can resume operation.

[0017] 2. The auxiliary dredging device for a jaw crusher in the example of the utility model, the bin can accommodate a plurality of dredging top arms, so that after the jaw crusher is dredged, the dredging top arms are hidden in the movable jaw body, which will not affect the normal operation of the jaw crusher and has a good use effect.

[0018] 3. In the auxiliary dredging device for the jaw crusher of the utility model, during the vertical movement of the first slide, the pushing inclined surface is used to enable the dredging top arm to be inserted into the gap between the stone and the movable jaw plate, and the extrusion surface is used to separate the stone abutting against the movable jaw plate from the movable jaw plate so that the stone can be discharged smoothly; since the dredging top arm can be embedded and slidably connected in the crushing tooth groove, when the stone applies a horizontal reaction force to the dredging top arm, the movable jaw plate can limit the dredging top arm to avoid bending and damage of the dredging top arm, and the service life is long.

[0019] 4. In the auxiliary dredging device for a jaw crusher of the utility model, a plurality of dredging top arms can slide freely in their respective corresponding sleeves, so that the plurality of dredging top arms abut against the lower side of stones at different heights, thereby improving the dredging effect of the jaw crusher.
