AI Technical Summary

Technical Problem

The existing concrete mixer trucks are inconvenient to adjust their position during the unloading process, and the concrete is dry and thick and easy to stick to the unloading pipe due to high temperature, affecting the unloading efficiency.

Method used

A concrete mixer truck is designed, using a servo motor to drive the rotary rod and the connecting sleeve, and rotates in the connecting pipe through the first and second connecting rings, driving the unloading pipe to rotate back and forth, achieving flexible adjustment of the unloading position. At the same time, drive the cam and tapping rod by driving the motor to prevent concrete from sticking to the discharge pipe.

Benefits of technology

It improves the convenience of adjusting the concrete unloading position, reduces the movement adjustment of operators, improves the unloading efficiency, and prevents concrete from agglomerating on the unloading pipe, ensuring a smooth unloading process.

Abstract

The present invention discloses a concrete mixer truck and a control method and system thereof, which relates to the technical field of mixer trucks for construction, and includes a truck base, a mixing drum and a feed hopper. The truck base is provided with a discharge assembly, and the truck base is provided with a knocking assembly. The discharge assembly includes a discharge hopper, and the bottom of the discharge hopper is fixedly connected with a connecting pipe, and the inside of the connecting pipe is rotatably connected with a first connecting ring, and the bottom of the first connecting ring is fixedly connected with a second connecting ring, and the bottom of the second connecting ring is fixedly connected with a discharge pipe, and the top of the truck base is fixedly connected with a mounting box. The servo motor drives the rotating rod to rotate forward and reverse, so that the connecting sleeve and the connecting rod rotate in the same direction. At this time, the first connecting ring and the second connecting ring rotate in the connecting pipe. Through the coordinated use of the above structure, the discharge pipe is driven to rotate back and forth, which is used to adjust the discharge position of the discharge pipe, so as to achieve the purpose of convenient adjustment of the concrete discharge position.
