Mechanical two-degree-of-freedom controllable loading machine

Abstract

The invention discloses a mechanical two-degree-of-freedom controllable loading machine. A bucket turning crank-link mechanism consists of two four-bar mechanisms which are connected in series with each other; a loading arm driving mechanism is a crank-rocker mechanism; the three cranks are driven by three controllable motors respectively; any track output of an output end is realized in a working space by programming; and turning of a bucket is matched with lifting of the arm of the loading machine, and actions such as attitude keeping, adjusting and the like are realized by programming a control motor. The mechanical two-degree-of-freedom controllable loading machine can overcome the defects of simple action and difficult control of the traditional mechanical loading machine, and also can overcome the defects of high requirement on a hydraulic element, easy oil leakage, low reliability and the like of the hydraulic loading machine.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a mechanical two-degree-of-freedom controllable loader. Background technique [0002] There are two main types of loaders: mechanical and hydraulic. The mechanical loader has a history of several decades. It uses mechanical transmission parts to realize the loading action, and has the advantages of being strong and durable. But traditional mechanical loaders cannot complete complex actions. Hydraulic loaders have the advantages of simple structure, light weight, and many complex actions, and are widely used. However, the hydraulic loader uses hydraulic oil as the medium for power transmission, and its starting performance is poor. Because the internal components are worn out, leakage is likely to occur, and there are many components involved. The leaked hydraulic oil will cause environmental pollution. At the same time, the hydraulic pressure System oil is affected by ambi...

AI Technical Summary

Problems solved by technology

However, the hydraulic loader uses hydraulic oil as the medium for power transmission, and its starting performance is poor. Because the internal components are prone to leakage after wear and tear, and there are many components involved, the leaking hydraulic oil will cause environmental pollution. At the same time, hydraulic pressure System oil is affected by ambient temperature, especially in high-cold and high-pressure environments

At present, there is a consensus in the field of construction machinery: the actions that mechanical loaders can complete are simple and difficult to change, and many actions cannot be realized; hydraulic loaders can flexibly perform various engineering actions, but there are high requirements for hydraulic system components, Defects such as short lifespan and oil leakage
