Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a stone crusher. Background Art

[0002] In fields such as construction materials, road paving, and geological exploration, stone crushing testing is a crucial experimental process used to evaluate the mechanical properties and crushing characteristics of stones. The design of traditional stone crushers primarily relies on the combination of a pressure cylinder, an indenter, and an external press. During operation, the stone to be tested is first placed in the pressure cylinder, followed by the installation of the indenter, and a press applies vertical downward pressure until the stone is crushed. However, after the crushing test, sample removal and equipment disassembly are often cumbersome and time-consuming, becoming a key factor limiting test efficiency.

[0003] When the stone crusher in the prior art is in use, the press applies pressure to the pressure head to crush the stone, which makes the close fit between the bottom plate and the pressure cylinder complicated, and usually requires the use of tools or additional force to separate them. At the same time, the connection between the pressure head and the upper part of the pressure cylinder is also tight, and the accumulation of debris generated after the stone is crushed further aggravates the difficulty of disassembly, thereby increasing the difficulty of separating the bottom plate and the pressure head, increasing labor intensity, and extending the test period. Utility Model Content

[0004] The utility model aims to provide a stone crusher, which can discharge the crushed stones through the provided baffle and the discharge port, thereby solving the problem of overtightening when the bottom plate and the pressure head are removed.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a stone crusher, comprising a base plate, a pressure-bearing cylinder and a pressure head. The base plate is equipped with a pressure-bearing cylinder, the pressure head is installed on the pressure-bearing cylinder, a blanking port and a receiving groove are provided in the base plate, the receiving groove and the blanking port are connected, a baffle is slidably fitted in the receiving groove, a transverse plate is provided on the outer surface of the baffle, a slide groove fitted with the transverse plate is provided on the base plate, the slide groove is connected with the receiving groove, a rectangular frame is provided on the outer surface of the base plate, a fixed cylinder is installed in the rectangular frame, an insertion rod is slidably fitted in the fixed cylinder, a spring is connected between the top of the insertion rod and the fixed cylinder, and a jack fitted with the insertion rod is provided on the transverse plate.

[0007] Furthermore, a buffer pad is installed on the blanking port, and the buffer pad contacts the outer surface of the baffle.

[0008] Furthermore, the baffle is located in the blanking opening.

[0009] Furthermore, a stopper is installed on the horizontal plate, and the stopper contacts the outer surface of the rectangular frame.

[0010] Furthermore, a pull rod is installed on the top of the insertion rod, a through hole is opened on the rectangular frame, and the pull rod is fitted in the through hole.

[0011] Furthermore, a handle is installed on the bottom plate, and a cross bar is installed on the pressure head.

[0012] The utility model has the following beneficial effects:

[0013] The utility model discharges the crushed stones through the baffle plate and the discharge port, thereby facilitating the smooth removal of the bottom plate from the bottom of the pressure cylinder. Due to the partial discharge of stones, the friction between the pressure head and the stone fragments is reduced, making the removal of the pressure head easier, and the entire removal process smoother and more efficient, thereby improving work efficiency and reducing the risk of equipment damage.

[0014] The utility model provides a plug rod and a spring to facilitate the fixed position of the baffle plate. The operation is simple and convenient. The operator can quickly remove the baffle plate to partially release the stone, thereby quickly starting the disassembly process of the base plate and the pressure head. This greatly shortens the non-testing time in the test cycle and improves the overall test efficiency. Of course, any product implementing the utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A chute 105 that cooperates with the cross plate 3 is provided on the bottom plate 1. The chute 105 is connected to the receiving slot 104. By pulling the pull rod 8 toward the top, the insertion rod 6 releases the limit on the cross plate 3, and then pulling the block 9 drives the cross plate 3 to pull the baffle 2 out of the blanking port 102. The stones are moved out to the storage groove 104 for storage.
