Miniature multi-freedom-degree controllable mechanical type crowd shovel excavating loading mechanism

Abstract

A miniature multi-freedom-degree controllable mechanical type crowd shovel excavating loading mechanism comprises a machine frame, a first branch chain, a second branch chain, a third branch chain and a bucket. The first branch chain, the second branch chain and the third branch chain are driven by a servo motor installed on the machine frame, and actions of excavating, shoveling, discharging and the like are achieved through mutual matching of the first branch chain, the second branch chain and the third branch chain to jointly finish the excavating loading operations. The excavating loading mechanism has the working space and flexibility of a traditional loader, meets the loading requirements, further can perform excavating operation, meets certain excavating requirements and avoids the shortcomings of high manufacture cost, complex maintenance and the like of a hydraulic element of the hydraulic loader. By adopting the servo motor for driving, automation and numerical control can be achieved easily, and compared with other excavating loading mechanisms, the miniature multi-freedom-degree controllable mechanical type crowd shovel excavating loading mechanism is simple in structure, low in manufacture cost, easy to maintain and particularly suitable for manufacturing miniature excavating loading all-in-one machines.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a miniature multi-degree-of-freedom controllable mechanism-type front shovel excavating and loading mechanism. Background technique [0002] A backhoe loader is a single unit consisting of three pieces of construction equipment. A backhoe loader includes: powertrain, loading end, and digging end. Each device is designed for a specific type of work. On a typical construction site, an excavator operator often needs to use all three components to get the job done. Due to the different requirements for the degree of freedom of the working device in the loading operation and the excavating operation, when the loading operation is performed, it is necessary to control the loading end to complete it, and when the excavation task is required, the excavation end is required to complete it. Lower, higher maintenance costs. [0003] With the development of motor technology and the i...

Problems solved by technology

Due to the different requirements for the degree of freedom of the working device in the loading operation and the excavating operation, when the loading operation is performed, it is necessary to control the loading end to complete it, and when the excavation task is required, the excavation end is required to complete it. Lower, higher maintenance costs

[0003] With the development of motor technology and the improvement of control technology, the multi-degree-of-freedom controllable mechanism provides a broad development space for construction machinery. The linkage mechanism is low in manufacturing cost, reliable and durable, and the control system is simple. Micro-engineering machinery, because of the small load-carrying capacity, the force of the connecting rod mechanism is not large, and the controllable mechanism is more practical. Since the hydraulic transmission is replaced by the connecting rod mechanism, when the active rod is driven by a servo motor, it is easy to realize automation and numerical control. control, but there are not many types of multi-degree-of-freedom controllable micro-excavation loading mechanisms, and some of them have complex structures, which are difficult to apply to engineering practice
