Problems solved by technology
[0003] The object of the present invention is to provide a space-controllable mechanism loader with a three-dimensional rotating boom and one-dimensional rotating bucket, which is driven by a controllable motor and driven by a connecting rod. The shortcomings of high machining accuracy requirements, high maintenance costs, difficulty in ensuring reliability, and easy oil leakage can also solve the problem that flat loaders can only achieve trajectory output in the plane, resulting in inflexible movements, limited working space, and poor working conditions. low efficiency

The invention relates to a space-controllable mechanism type loader with a three-dimensional rotating movable arm and a one-dimensional rotating bucket, comprising a vehicle, the movable arm, the bucket, four driving rods, four connecting rods and five servo motors; the movable arm can rotate three-dimensionally independently; the bucket can rotate one-dimensionally independently; and the whole loader can realize the output of four degrees of space motion. The space-controllable mechanism type loader can effectively overcome the defects of high requirement for the processing precision of the hydraulic elements, high maintenance cost, difficult guarantee of reliability and easy oil leakage of the hydraulic loader and solve the problems of inflexible motion, limited work space and low work efficiency due to the output of the trajectory only in the plane of the plane loader.
Description
technical field [0001] The invention relates to the field of loaders, in particular to a space-controllable mechanism loader with a three-dimensional rotating boom and one-dimensional rotating bucket. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in road, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime, coal, etc. Hard soil, etc. for light shoveling and digging operations. Most of the traditional loaders are hydraulically driven, and there are problems that have not been solved for a long time in the field of construction machinery, such as high processing and assembly requirements for hydraulic system parts, short service life, oil leakage, and high maintenance costs. Most of the mechanisms are planar mechanisms. The boom is lifted and lowered by the drive of the boom hydraulic cylinder, and the bucket is turned by the driv...
