[0002] The jaw crusher crushes stones by the swing of the movable jaw in coordination with the fixed jaw. The jaw crusher is usually installed on a cement base. During the swing of the movable jaw, the crusher vibrates, causing the crusher to continuously impact the cement base back and forth. Over time, the cement base may be shattered by the impact of the crusher, and the crusher cannot be properly fixed, affecting the normal operation of the crusher. Utility Model Content

[0003] The purpose of the utility model is to provide a jaw crusher mounting base, which is used to overcome the above-mentioned defects in the prior art.

[0005] Through the above technical solution, a mounting body that can move inside the seat is fixed to the jaw crusher. As the movable jaw of the jaw crusher swings, the mounting body moves back and forth inside the seat. The elasticity of the elastic buffer body cushions the movement of the mounting body, thereby reducing the impact of the jaw crusher on the cement base during the crushing operation.

[0006] Furthermore, a plurality of bolts are fixed on the upper end surface of the mounting body, the bolts pass through the bottom of the jaw crusher, nuts are threaded on the bolts, and the mounting body is fixed to the bottom of the jaw crusher through the threaded connection between the bolts and the nuts.

[0007] The above technical solution facilitates the detachable installation of the crusher on the installation body.

[0008] Furthermore, the mounting body is provided with strip grooves on both sides parallel to the swinging direction of the movable jaw of the jaw crusher, and a strip through groove is provided between the two strip grooves, and a number of equally distributed limiting wheel axles are arranged in the strip through grooves, and the axis of the limiting wheel axle is perpendicular to the line connecting the two ends of the strip through grooves, and the two ends of the limiting wheel axle respectively pass through the strip grooves on both sides and are fixed on the side walls of the cavity, and two limiting wheels are rotatably connected to the outer periphery of the limiting wheel axle, and the two limiting wheels on the same limiting wheel axle are respectively located in the two strip through grooves, and the outer periphery of the limiting wheel axle abuts against the lower side wall of the strip groove, and a number of supporting wheel axles parallel to the limiting wheel axle are fixed on the lower side of the mounting body, and two support wheels are rotatably connected to the outer periphery of the support wheel axle, and the outer periphery of the support wheel abuts against the lower end face of the mounting body.

[0009] Through the above technical solution, the support wheels support the installation body, and the limiting wheels limit the vertical movement of the installation body, so that the installation body can only move in the horizontal direction, ensuring the vertical stability of the crusher during the operation of the crusher.

[0010] Furthermore, the elastic buffer body is made of rubber, and an accommodating cavity which is concave downward and passes through the elastic buffer body is formed on the upper end surface of the elastic buffer body, and the mounting body is located in the accommodating cavity.

[0011] Through the above technical solution, the elastic buffer body made of rubber can improve the buffering effect on the installation body.

[0012] Furthermore, the number of the supporting wheel axles is equal to and corresponds one to one with the limiting wheel axles, and the two side walls of the accommodating cavity perpendicular to the axis of the limiting wheel axle are provided with a number of vertical downward slots, and the lower ends of the slots are open, and the number of the slots is equal to and corresponds one to one with the limiting wheel axles.

[0013] Through the above technical solution, the provision of the clamping groove on the elastic buffer body facilitates the installation of the elastic buffer body in the gap between the mounting body and the side wall of the cavity.

[0014] Furthermore, the base is embedded in concrete, and the upper end surface of the mounting body is higher than the upper surface of the concrete.

[0015] Through the above technical solution, the upper end surface of the installation body is higher than the upper surface of the concrete, which can avoid friction between the crusher floor and the concrete surface.

[0016] The beneficial effect of the utility model is that a mounting body that can move within the seat is fixed to the jaw crusher. As the movable jaw of the jaw crusher swings, the mounting body moves back and forth within the seat. The elasticity of the elastic buffer body cushions the movement of the mounting body, thereby reducing the impact of the jaw crusher on the cement base during the crushing operation.
