A crushing device for concrete production

Technical Field

The utility model relates to the technical field of concrete production, in particular to a crushing device for concrete production.

Background Art

Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; cement concrete obtained by mixing with water (which may contain admixtures and additives) in a certain proportion and stirring is widely used in civil engineering. The sand and stone in concrete are also called aggregates. These aggregate raw materials are of different sizes and need to be crushed by crushing rollers. When currently used, most aggregate crushing devices use two crushing rollers rotating in opposite directions to squeeze the aggregate raw materials and then crush the aggregates. However, it is difficult to crush all the aggregates to meet the use requirements in one crushing process, and further processing is required, resulting in low work efficiency. To this end, we provide a crushing device for concrete production to solve the above problems.

The rocker 12 is rotatably connected to the slot rod 9 through a pin shaft. The operation of the second motor 10 can drive one end of the rocker 12 to rotate through the eccentric shaft 11, and then the movement of the rocker 12 can drive the slot rod 9 to reciprocate and move horizontally on the top of the fixed block 8, thereby providing power for the movement of one of the movable extrusion plates 7.

Specifically, the crushing assembly includes a support plate 2 installed in the inner cavity of the box body 1 and directly below the first motor 3. The first motor 3 and the dual-axis reducer 4 are installed on the top of the support plate 2. The output end of the first motor 3 is connected to the input end of the dual-axis reducer 4. The two output ends of the dual-axis reducer 4 are connected to crushing rollers 5. The other end axes of the two crushing rollers 5 are rotatably connected to the inner wall of the box body 1 through bearings. The first motor 3 can drive the two crushing rollers 5 to rotate inwardly toward each other through the dual-axis reducer 4, thereby realizing secondary crushing of the aggregate raw materials.

Specifically, the screening assembly includes two groups of springs 13, which are longitudinally installed on both sides of the inner cavity of the box body 1 respectively. Filter plates 14 are installed on the top of the two groups of springs 13. The lower end of the slope of the filter plate 14 is located in the coarse material outlet. A vibration motor 15 is installed on the bottom frame of the filter plate 14.

The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

Working principle: When the crushing device is in use, the user can start the first motor, the second motor and the vibration motor at the same time, and then put an appropriate amount of concrete aggregate raw materials into the hopper. At this time, the second motor can drive one end of the rocker to rotate through the eccentric shaft, and then the movement of the rocker can drive the slot rod to move back and forth on the top of the fixed block. At this time, the slot rod can drive one of the extrusion plates to squeeze the other extrusion plate, and the raw materials falling in the hopper can be crushed for the first time between the two extrusion plates. The crushed raw materials can fall between the two crushing rollers through the orifice plate. Through the work of the first motor, the first motor can drive the two crushing rollers to rotate towards each other through the double-axis reducer, and then drive the two crushing rollers to crush the raw materials for the second time. The finished product rate of the aggregate raw materials after the two crushing processes has been improved to a certain extent. In order to ensure that a small amount of unqualified aggregate raw materials are mixed in the finished aggregate, the filter plate can be driven by the vibration motor for vibration screening, and a small amount of unqualified aggregate raw materials can be screened out at the coarse material outlet, and the finished aggregate falls to the slope of the inclined block at the filter plate and slides out to the fine material outlet by gravity.
