Description

Technical Field

[0001] This utility model relates to the field of shotcrete machine technology, and in particular to a material crushing device for shotcrete machines. Background Technology

[0002] A shotcrete machine is a mechanical device used to spray a mixed slurry (usually cement, gypsum, mortar, etc.) onto a surface or structure. Shotcrete machines are mainly used in underground engineering, tunnel construction, mine reinforcement, wall plastering and other fields to reinforce, repair or decorate the structure of buildings.

[0003] In shotcrete operations, lumps or clumps of a certain size are often mixed in with the material. Existing shotcrete machine crushing devices mostly use a single rotating crushing rod structure. When dealing with these lumps, the lumps are prone to sliding in the crushing chamber or being only partially struck by the crushing rod, resulting in low crushing efficiency. The lumps that are not fully crushed are very likely to cause blockage of the conveying pipeline during subsequent transportation, thus affecting the continuity of shotcrete operations and construction efficiency. Therefore, this utility model proposes a crushing device for shotcrete machines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem that during shotcreting operations, materials often contain lumps or clumps of a certain size. Existing shotcreting machine crushing devices mostly use a single rotating crushing rod structure. When dealing with these lumps, they are prone to sliding within the crushing chamber or being only partially struck by the crushing rod, resulting in low crushing efficiency. Insufficiently crushed lumps can easily cause blockages in the conveying pipeline during subsequent transportation, thus affecting the continuity and efficiency of shotcreting operations. Therefore, this invention proposes a crushing device for shotcreting machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crushing device for a shotcrete machine includes a feeding hopper, a horizontal plate fixedly installed on the top of the feeding hopper, and a positioning frame fixedly installed on the top of the horizontal plate. The crushing device of the shotcrete machine also includes: A transmission mechanism, located at the top of the positioning frame, is used to improve the crushing quality; A crushing mechanism is located at the bottom of the transmission mechanism and is used to crush agglomerated materials.

[0006] As a preferred embodiment of this utility model, the transmission mechanism includes: a first motor, a reciprocating lead screw, a threaded sleeve, and a transmission plate; The first motor is fixedly installed on the top of the positioning frame. The output end of the first motor is fixedly connected to the reciprocating lead screw. The bottom of the reciprocating lead screw passes through the positioning frame and is rotatably connected to the top of the horizontal plate through a rotating shaft. The surface of the reciprocating lead screw is movably connected to the inner cavity of the threaded sleeve. The top of the transmission plate is provided with a positioning hole. The inner cavity of the positioning hole is rotatably connected to the surface of the threaded sleeve through a rotating shaft.

[0007] As a preferred embodiment of this utility model, the crushing mechanism includes: a second motor, a first synchronous pulley, a synchronous belt, a second synchronous pulley, a transmission shaft, and crushing blades; The second motor is fixedly installed on the front side of the transmission plate. The output end of the second motor is fixedly connected to the first synchronous pulley. The surface of the first synchronous pulley is movably connected to the inner cavity of the synchronous belt. Both sides of the rear side of the inner cavity of the synchronous belt are movably connected to the surface of the second synchronous pulley. The bottom of the second synchronous pulley is fixedly connected to the transmission shaft. The bottom of the transmission shaft extends through the inner cavity of the feeding hopper. The bottom of the surface of the transmission shaft is fixedly connected to multiple crushing blades.

[0008] As a preferred embodiment of this utility model, a limiting hole is provided on the top of the positioning frame, and the inner cavity of the limiting hole is rotatably connected to the surface of the reciprocating lead screw through a rotating shaft.

[0009] As a preferred embodiment of this utility model, round holes are provided on both sides of the top of the transmission plate, and the round holes are matched with the transmission shaft.

[0010] As a preferred embodiment of this utility model, a stabilizing cylinder is fixedly installed on both sides of the bottom of the transmission plate, and the inner cavity of the stabilizing cylinder is rotatably connected to the surface of the transmission shaft through a rotating shaft.

[0011] As a preferred embodiment of this utility model, the inner cavity of the positioning frame is provided with sliding grooves on both sides, and the transmission plate is provided with sliding rails on both sides, with the sliding grooves and sliding rails being compatible. Beneficial effects

[0012] The first motor drives the reciprocating screw to rotate, causing the threaded sleeve to move along the surface of the reciprocating screw, which in turn drives the transmission plate to move up and down reciprocally. The transmission plate drives the entire crushing mechanism to continuously change position in the inner cavity of the feeding hopper, so that the crushing blades can crush the agglomerated material from different heights and angles. The first synchronous pulley is driven by the second motor to rotate, and the second synchronous pulley is driven to rotate through the synchronous belt. This causes the transmission shaft to drive multiple crushing blades to rotate in the inner cavity of the feeding hopper. Combined with the up-and-down reciprocating motion provided by the transmission mechanism, the crushing blades can continuously change position while rotating, forming a multi-directional and multi-angle crushing effect, effectively breaking up lumps and clumps, preventing material accumulation and blockage, and further improving the crushing quality and the stability of the shotcrete operation. In this invention, the combined use of the transmission mechanism and the crushing mechanism can effectively break up clumps and lumps, prevent material accumulation and blockage, and further improve the crushing quality and the stability of the shotcrete operation.
