A safe and reliable intelligent concrete mixer truck

Abstract

The invention relates to a safe and reliable intelligent concrete mixer truck which comprises a cab, a connecting device, a stirring machine, a front drive mechanism, a chassis, a rear drive mechanism and an auxiliary drive mechanism. The cab is connected with the chassis through the connecting device, the front drive mechanism is arranged bellow the cab, and the rear drive mechanism and the auxiliary drive mechanism are arranged below the chassis. The safe and reliable intelligent concrete mixer truck detects the road surface obstacle situation through an obstacle detecting mechanism, movement is achieved while the chassis height is increased through the auxiliary drive unit, collision with an obstacle in the transportation process is prevented, accordingly safe running of the mixer truck is ensured. Moreover, in an infrared remote control circuit, an integrated circuit is utilized to form a multivibrator, the duty ratio of pulse output is improved through a charge-discharge loop, the transmitting power of a third diode is improved, accordingly the transmitting power of an infrared remote control module is improved, the stable effectiveness of remote control is ensured, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to a safe and reliable intelligent concrete mixer truck. Background technique [0002] Concrete mixer truck, also known as ready-mixed concrete truck, is a special truck used to transport ready-mixed concrete for construction. Because of its shape, it is also often called snail truck. The truck is equipped with a circular mixing drum to carry the mixed concrete, and the mixing drum will always be kept rotating during transportation to ensure that the carried concrete will not solidify. [0003] Different from ordinary roads, the ground of the job site is usually uneven and accompanied by various obstacles. During the movement of the mixer truck at the job site, due to the low height of the chassis, it usually collides with various obstacles on the ground. The bottom of the mixer truck is easily damaged during transportation, which makes the mixer truck unable to continue to realize the transportation function. Not only that, in o...

[0003] Different from ordinary roads, the ground of the job site is usually uneven and accompanied by various obstacles. During the movement of the mixer truck at the job site, due to the low height of the chassis, it usually collides with various obstacles on the ground. The bottom of the mixer truck is easily damaged during transportation, which makes the mixer truck unable to continue to realize the transportation function. Not only that, in order to realize remote control operation, an infrared remote control module is usually installed inside the mixer truck, but the traditional infrared remote control circuit transmits low power, resulting in remote control effects. Instability often fails, reducing the usefulness of the mixer truck
