Problems solved by technology

[0004] In the existing hydraulic circuit drive mixer truck, the work of the oil pump is to transmit the PTO torque of the chassis to the oil pump through the transmission shaft. Since the speed of the vehicle changes during driving, the PTO output speed changes constantly, and it is impossible to control the rotation of the mixing drum at a constant speed.

Abstract

The embodiment of the invention discloses a mixing drum driving device which comprises a speed reducer and a main motor, wherein an output shaft of the speed reducer is connected with the input end of a mixing drum, and an output shaft of the main motor is connected with an input shaft of the speed reducer. According to the mixing drum driving device provided by the invention, a driving mode of the existing driving device is changed, and the mixing drum is driven to rotate by the motor and the speed reducer, so as not to be influenced by speed change of a truck in the running process. The invention further discloses a concrete mixer truck with the mixing drum driving device.

Description

technical field [0001] The invention relates to the technical field of concrete mixer trucks, and more specifically, relates to a mixing drum driving device and a concrete mixer truck. Background technique [0002] The concrete mixer truck is a special truck used to transport concrete for construction. Because of its shape, it is also often called a snail truck. These trucks all have cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum will always be kept rotating to ensure that the carried concrete will not solidify. [0003] At present, the transmission mode of traditional concrete mixer trucks on the market is to output power through the chassis PTO (POWER-TAKE-OFF, power take-off device), and drive the hydraulic oil pump to rotate through the transmission shaft. The hydraulic oil is pumped to the hydraulic motor through the high-pressure pipe, and then the hydraulic oil in the hydraulic motor is released into the hydraulic oil ta...
