It is usually made of cement as the cementing material, sand and stone as aggregates, and water in a certain proportion and mixed. It is widely used in the field of civil engineering. Piston concrete delivery equipment is a high-pressure pump that uses an electronically controlled hydraulic system to drive a sealed loop to deliver concrete to the construction site, which can improve the construction efficiency of later civil engineering projects.

The advantages of the utility model are: the concrete conveying equipment for a concrete mixing station can clean, repair or replace the internal parts by setting a detachable conveying pipe and a cover plate, and the equipment is fixed to the ground by setting a fixing plate, so that ground work can be carried out, which greatly improves the practicality of the concrete transporting equipment, and by setting a power device including a reduction motor and a protective net, when in use, the protective net is installed around the reduction motor, which can effectively prevent the impact of debris generated during construction, thereby protecting the reduction motor from being affected. At the same time, the setting of the protective net will not affect the heat dissipation of the motor;

[0004] When existing concrete conveying equipment conveys concrete, it basically directly conveys and mixes the concrete conveyed inside through the dragon blades. However, after the concrete is discharged, the conveying equipment does not have a cleaning mechanism to circulate and clean the concrete residues sticking to the inner wall of the conveying pipe, which will cause the residual concrete to stick to the inner wall of the conveying pipe and affect the subsequent conveying use.

[0005] Therefore, we proposed that piston-type concrete conveying equipment can solve the above problems well. Utility Model Content

[0006] The utility model aims to provide a piston-type concrete conveying equipment to solve the problem raised by the above-mentioned background technology that the existing concrete conveying equipment on the market basically directly uses dragon blades to convey and stir the concrete conveyed inside, but after the concrete is discharged, the conveying equipment does not have a cleaning mechanism to circulate and clean the concrete residues stuck on the inner wall of the conveying pipe, which will cause the residual concrete to stick to the inner wall of the conveying pipe and affect the subsequent conveying and use.
