Concrete pump consists of a pump body and a delivery pipe. It is mainly used in house construction, bridge and tunnel construction, and agricultural infrastructure construction. It is divided into gate valve concrete pump and S valve concrete pump. It is characterized by reverse pump function, automatic compensation of wear gap, good sealing performance and long service life. Its principle is to use compressed air to continuously transport the concrete stored in the tank along the pipeline.

[0003] At present, when a concrete pump is used, it is moved to a suitable place by being towed by a tractor, firmly supported by supporting legs, and then connected to a pipeline for use.

A filter plate for filtering debris in the concrete is usually installed in the existing hopper.

[0029] The implementation principle of the high-performance concrete delivery pump of the present application is as follows: when concrete needs to be used, concrete is first added from the top of the hopper 3 into the hopper 3, and then the concrete is filtered through the filter plate 4 and enters the bottom of the hopper 3, and the delivery pump 2 is started to deliver the concrete and use the concrete;

[0030] When it is necessary to clean the filter holes of the filter plate 4, the driving member 531 is first started to drive the screw rod 532 to rotate, drive the lifting plate 522, the lifting block 521 and the pushing rod 51 to rise, and when the lifting block 521 abuts against the pushing block 62 during the rising process, the pushing block 62 will squeeze the lifting block 521, so that the lifting block 521 slides along the length direction of the filter plate 4 and stretches the elastic member 7, and the lifting block 521 drives the pushing rod 51 to slide in the horizontal direction toward the filter hole, and then the lifting block 521 abuts against the vertical surface of the pushing block 62, and the lifting plate 522 drives the pushing rod 51 to continue to rise, and the pushing rod 51 is inserted into the filter hole and pushes out the debris in the filter hole, and then the operator can clean the debris on the upper surface of the filter plate 4 in time;
