Loading mechanism adopting MDOF (multiple degree of freedom) controllable connecting rods

Abstract

The invention discloses a loading mechanism adopting MDOF (multiple degree of freedom) controllable connecting rods. Two ends of a second driving lever of a lifting mechanism are connected with a stander and a first end of a first support frame respectively; two ends of a third connecting rod are connected with the stander and a second end of the first support frame, and a third end of the first support frame is connected with a bucket; two ends of a first driving lever of a bucket turnover mechanism are connected with the stander and one end of a first connecting rod respectively, the other end of the first connecting rod is connected with a first end of a second support frame, a second end of the second support frame is connected with one end of the a second connecting rod, a third end of the second support frame is connected with the second driving lever, and the other end of the second connecting rod is connected with the bucket. The loading mechanism can solve the defects that a traditional hydraulic loading machine is complicated in system, easy to leak oil, high in machining precision requirement and the like, and has the advantages of an MDOF controllable mechanism type loading machine, such as flexibility, rapid action and the like; moreover, a connecting rod transmission part is more simple, each rod and each joint bear force batter, and a work space is larger, so that the loading mechanism is more suitable for manufacturing various loading machines and other engineering machinery.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a multi-degree-of-freedom controllable link loading mechanism. Background technique [0002] In the field of construction machinery today, loaders are one of the most important construction machinery, and most of the current loaders are full hydraulic full-slewing loaders. The full hydraulic loader is also undergoing continuous improvement and innovation of control methods, so that the loader has developed from simple lever control to hydraulic control, pneumatic control, hydraulic servo control and electrical control, radio remote control, and computer integrated program control. However, hydraulic loaders also have many deficiencies and shortcomings. First, hydraulic components require high machining accuracy, high cost, strict assembly requirements, difficult manufacturing, and high technical and difficult maintenance requirements during use; secondly, hydraulic oil is aff...
