Problems solved by technology

However, the hydraulic excavator uses hydraulic oil as the power transmission medium, and its startup is poor, and it is easy to leak due to the wear of internal components, and there are many components involved, and the leaked hydraulic oil will cause environmental pollution.
At the same time, there will be overheating, inability to work, etc.
With the increase of the functions of the loader, its hydraulic system becomes more and more complex, and the occurrence of faults is more sudden and hidden
[0003] Although the hydraulic loader can perform various engineering actions flexibly, it is still a very difficult problem in the field of construction machinery due to its high requirements for hydraulic system parts, long life, oil leakage and other defects, and it has not been able to make a breakthrough for a long time. the puzzle

Embodiment Construction

[0023] control figure 1 and figure 2 , the loading and lifting mechanism is a planar single-degree-of-freedom controllable mechanism, which is composed of a first active rod 1 , a first driven rod 2 , a lifting arm 3 and a frame 24 . One end of the first active rod 1 is hinged to one end of the first driven rod 2 through the fifth hinged hole 15, the other end is hinged to the frame through the first hinged hole 11, and the other end of the first driven rod 2 is hinged through the sixth hinged hole 16 is hinged with the lifting arm 3, one end of the lifting arm 3 is hinged on the frame through the third hinge hole 13, and the other end is hinged with the bucket 10 through the seventh hinge hole 17. The first active rod 1 is controlled by the servo motor 27, and the lifting and lowering of the front end of the lifting arm 3 in the working space is realized through programming.

Abstract

The invention relates to a planer multiple degree of freedom controllable loading mechanism. The raise-rise arm of the loading mechanism is a planer single degree of freedom controllable mechanism, wherein one end of the raise-rise arm is hinged on the chassis, and the other end is hinged a bucket; and a bucket rollover mechanism is linked between the bucket and the chassis. By using the invention, the problem that the hydraulic system of the traditional hydraulic loading machine has high demand on parts and short service life and leaks oil, etc can be solved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a plane multi-degree-of-freedom controllable loading mechanism. Background technique [0002] Existing loaders are mainly hydraulic transmission, which has the advantages of simple structure, light weight, and can realize many complex actions, etc., and is widely used. However, the hydraulic excavator uses hydraulic oil as the power transmission medium, and its startup is poor, and it is easy to leak due to the wear of internal components, and there are many components involved, and the leaked hydraulic oil will cause environmental pollution. At the same time, there will be overheating and inability to work. With the increase of the functions of the loader, its hydraulic system becomes more and more complex, and the occurrence of faults is more sudden and concealed. [0003] Although the hydraulic loader can perform various engineering actions flexibly, it is still a very d...
