Description

Technical Field

[0001] The utility model relates to the technical field of lining plates, in particular to an adjustable lining plate for a sand making machine. Background Art

[0002] The liner is used to protect the cylinder from direct impact and friction between the grinding body and the material, which helps to improve the grinding efficiency of the mill, increase output and reduce metal consumption. Therefore, the liner is very popular. For example, the patent subject "Wear-resistant liner for sand making machine", application number "202221008652.6", can crush the stone when it hits the liner by setting the raised module A and the raised module B, thereby reducing the burden of the hammer in the sand making equipment. The liner can use the raised module A and the raised module B to crush the stone when it hits the sand making machine, so that the stone crushing efficiency is poor. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides an adjustable lining plate for a sand making machine, which utilizes the sharp knife points at the top of the transverse kettle knife and the longitudinal kettle knife to perform secondary crushing on the impacted stones, thereby improving the crushing efficiency of the stones in the sand making machine and solving the above-mentioned technical problems.

[0004] To achieve the above object, the utility model provides the following technical solution: comprising a lining plate, wherein a crushing plate is arranged on the upper surface of the lining plate, and metal plates are fixedly connected to both sides of the crushing plate, and bolts are connected to the internal threads of the metal plates;

A horizontal kettle knife is fixedly connected to the upper surface of the crushing plate, and a longitudinal kettle knife is fixedly connected to the upper surface of the crushing plate.

[0006] Through the above technical scheme, the horizontal and vertical kettle knives are staggered in the horizontal and vertical directions, so that when the liner is connected to the inner wall of the external sand making machine, the crushed stones in the sand making machine can collide with the horizontal and vertical kettle knives, and the sharp knife points at the top of the horizontal and vertical kettle knives can be used to crush the collided stones for the second time.

[0007] As a preferred technical solution of the utility model, a frame is fixedly connected to the lower surface of the lining plate, and a rubber pad is arranged inside the frame.

[0008] Through the above technical scheme, the friction between the rubber pad and the inner wall of the sand making machine is utilized to increase the contact area between the liner and the inner wall of the sand making machine, so that when the stones in the sand making machine hit the liner, the liner is not easy to shake.

[0009] As a preferred technical solution of the utility model, a connecting block is fixedly connected to the front surface of the lining plate, a movable plate is movably connected to the front surface of the connecting block via a bearing, and a baffle is fixedly connected to the lower surface of the movable plate.

The conical setting of the thorn rod can enable it to slightly enter the bottom of the sand making machine entrance, thereby improving the grip of the extrusion plate.

[0015] As a preferred technical solution of the utility model, the internal threads of the clamping plate are connected with a threaded rod, and the threaded rod is fitted with the extrusion plate.

[0016] Through the above technical scheme, the threaded rod is twisted so that it can continuously push the extrusion plate to push, so that the extrusion plate can drive the thorn rod and the rubber block to squeeze the lower part of the sand making machine entrance, so that the threaded rod can fix the extrusion plate.

[0017] As a preferred technical solution of the utility model, a bolt sleeve is embedded and connected inside the circular hole, a rubber ring is arranged inside the bolt sleeve, and the rubber ring is sleeved with the bolt.

[0018] Through the above technical solution, the bolt can extend into the interior of the bolt sleeve, so that the rubber ring can be sleeved on the surface of the bolt.

The crushed stones in the sand making machine can collide with the horizontal and vertical kettle knives when the liner is connected to the inner wall of the external sand making machine. The sharp knife at the top of the horizontal and vertical kettle knives can be used to perform secondary crushing on the collided stones, thereby improving the crushing efficiency of the stones in the sand making machine.

[0021] 2. The utility model twists the threaded rod to continuously push the extrusion plate, so that the extrusion plate can drive the thorn rod and the rubber block to squeeze the lower part of the entrance of the sand making machine, so that the threaded rod can fix the extrusion plate, and the conical setting of the thorn rod can make it slightly enter the lower part of the entrance of the sand making machine, and the rubber seat can increase the friction between the thorn rod and the lower part of the entrance of the sand making machine, so that it can increase the grip of the extrusion plate, so that the liner can be directly installed on the outer surface of the sand making machine during installation, thereby improving the convenience of installing the liner.
