Loader working device capable of controlling bucket to rotate by motor

Abstract

The invention discloses a loader working device capable of controlling a bucket to rotate by a motor, and belongs to the technical field of mechanical structures. The loader working device capable ofcontrolling the bucket to rotate by the motor comprises a movable arm, a movable arm oil cylinder, a controller, the self-locking reduction motor and the bucket, wherein one end of the movable arm oilcylinder is connected with a loader; the other end of the movable arm oil cylinder is connected with the movable arm; one end of the movable arm is connected with the loader; the end portion of the other end of the movable arm is respectively provided with the self-locking reduction motor and the bucket; the rear portion of the bucket is provided with a rotating shaft; the rotating shaft and thebucket are relatively fixed; an output shaft of the self-locking reduction motor is connected with the rotating shaft of the bucket through a transmission device; and the controller is respectively connected with a bucket rotation angle measuring sensor, a movable arm oil cylinder length monitoring sensor, the self-locking reduction motor and a hydraulic control valve for controlling the movable arm oil cylinder. According to the loader working device capable of controlling the bucket to rotate by the motor, the mechanism design of the loader working device is greatly simplified, and the bucket can conveniently obtain a sufficient collection angle and a large discharge angle at any height.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and in particular relates to a loader working device controlled by a motor to control the revolving bucket of the bucket. Background technique [0002] like figure 1 As shown, the existing loader realizes lifting and lowering of the entire working device by extending and retracting the boom cylinder SQ, and realizes bucket retraction and unloading of the bucket by extending and retracting the bucket cylinder GF. The most core part of the working device of the loader is the bucket mechanism, namely figure 1 In the G-F-E-D-C-B, and the requirements of the working device mechanism for the bucket mechanism are relatively strict, the main performance is that in the entire working space of the loader working device, the ∠GFE, ∠EDC, and ∠DCB of the bucket mechanism should not be too large. It can't be too small. If it is too small or too large, the transmission angle of the mechanism wi...

Problems solved by technology

At present, the design method of obtaining an ideal mechanism by repeatedly adjusting the mechanism data for trial calculation is low in design efficiency. Designers often spend days or even weeks of trial calculations and may not be able to obtain a suitable mechanism.
