Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] The invention provides an energy-saving stirring device of a concrete mixing transport vehicle. see figure 1 As shown, the concrete mixer truck mainly includes structures such as a power take-off, a reducer, a mixing drum, a hydraulic system, and a vehicle chassis. The power take-off takes out the power of the engine and is used to drive the pumping mechanism of the hydraulic system to work, so that the pressurized hydraulic oil is supplied to the motor to drive the mixing drum to rotate.

[0038] The specific structure of the energy-saving device of the present invention is as figure 2 and 3As shown, it consists of a power part and an energy-saving ...

Abstract

The invention provides an energy-saving stirring device of a concrete mixing carrier. The energy-saving stirring device comprises a pump, a three-position four-way reversing valve, a stirring motor, a stirring drum and an energy-saving subsystem, wherein the energy-saving subsystem comprises a first shuttle valve, a first two-position two-way pilot operated directional control valve, a second shuttle valve, a second two-position two-way pilot operated directional control valve, a power generation motor, a direct-current generator and a storage battery. By means of a logic loop formed by the two two-position two-way pilot operated directional control valves and the two shuttle valves, in the process that the stirring drum stops rotating, no matter whether the stirring drum rotates in the forward direction or the reverse direction, hydraulic oil used for power generation can only drive the power generation motor to rotate in the same direction, so that direct-current power generation is completed, energy recycling is achieved, the complexity of a regeneration loop is reduced, the operation cost is saved, and the integration level is high.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to an energy-saving mixing device and an energy-saving method. Background technique [0002] The concrete mixer truck is the main supporting equipment of the concrete pump truck, mainly composed of a car chassis and a special device for concrete transportation. Its special devices mainly include power take-off, front and rear brackets of mixing drum, reducer, hydraulic system, mixing drum, control structure, cleaning system, etc. The power source for the rotation of the concrete mixing drum mainly consists of two forms. One is that the mixing drum rotates and the car chassis share one engine, that is, centralized drive; the other is that the mixing drum rotates with a separate engine, that is, it is driven independently. Both types of drive have their own unique advantages. For example, the centralized drive mode has small equipment and is often used in small-capacity conc...
