Automatic discharge system and concrete mixing vehicle

Abstract

The invention discloses an automatic discharge system which is used for discharge of a concrete mixing vehicle. The automatic discharge system comprises a driving and positioning control device of a discharge groove and a locking device, wherein the driving and positioning control device of the discharge groove comprises a revolution driving device and a lifting device, the discharge groove can achieve a predetermined revolution angle through the revolution driving device and achieve a predetermined inclination angle through the lifting device; and the locking device is mounted at the rear part of the concrete mixing vehicle and can lock the discharge groove in a non-working state. The driving and positioning control device of the discharge groove can control the discharge groove to fast and accurately achieve the predetermined revolution angle and the predetermined inclination angle, and when the discharge groove achieves the predetermined working position, and repeated adjustment is not required, so that the discharge process of the concrete mixing vehicle is further accelerated. The invention further discloses a concrete mixing vehicle comprising the automatic discharge system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic unloading system. In addition, the present invention also relates to a concrete mixer truck comprising the above automatic unloading system. Background technique [0002] Concrete mixer truck (cement mixer, concrete mixer) is a special truck used to transport concrete for construction; because of its shape, it is also often called a snail truck. [0003] A cylindrical mixing drum is installed on the concrete mixer truck to carry the mixed concrete. During the transportation of the concrete mixer truck, the mixing drum will always keep rotating to ensure that the transported concrete will not solidify during transportation. After transporting the concrete, the inside of the mixing drum is usually washed with water to prevent the concrete remaining on the inner wall of the mixing drum from hardening, and the hardened concrete will occupy the space of th...

AI Technical Summary

Problems solved by technology

Generally, the working environment of the construction site of concrete mixer trucks is relatively harsh. Manually adjusting the discharge chute 04 is labor-intensive on the one hand, and on the other hand, it will threaten the personal safety of operators.

[0007] For an improved method, please refer to the patent CN101508259A. The hydraulic system is used to drive the rotation and lifting of the discharge chute 04. The movement process of the discharge chute 04 needs to be adjusted by the operator while observing. Repeated observation and adjustment are required to achieve accurate discharge. Material position, the adjustment process is more complicated and time-consuming
