A multi-link loading mechanism

Abstract

The invention discloses a multi-connecting rod loading mechanism, which comprises a first driving rod, a first connecting rod, a swinging arm, a pull rod, a movable arm, a movable arm elevating mechanism and a scraper bucket, wherein one end of the movable arm is connected with a frame, and the other end of the movable arm is connected with the scraper bucket and is elevated and lowered under theaction of the movable arm elevating mechanism; one end of the first driving rod is connected with the frame, and the other end of the first driving rod is connected with the first connecting rod; thefirst connecting rod is connected with the swinging arm; one end of the swinging arm is connected to the movable arm, and the other end of the swinging arm is connected with the pull rod; the other end of the pull rod is connected with the scraper bucket; and the first driving rod is used for controlling the scraper bucket to rotate around the movable arm under the driving action of a motor. In the invention, a hydraulic transmission system is replaced by the multi-connecting-rod loading mechanism, so that the defects of high maintenance cost and the like of a hydraulic excavator are overcome; and simultaneously, the first connecting rod, the swinging arm and the pull rod are connected with one another, so that the strange phenomenon and an oversize or undersize transmission angle among the first connecting rod, the swinging arm and the pull rod due to the approach or reach of the scraper bucket of a mechanical loader to a limit position can be avoided easily on the premise of meetingthe requirement of loading, and the reliability of an electric loader is improved.

Description

technical field [0001] The invention relates to the field of loaders, in particular to a multi-link loading mechanism. Background technique [0002] Construction machinery is a general term for construction machinery used in engineering construction, and loaders are one of the most important construction machinery. Loaders are widely used as earth-rock construction machinery in construction projects such as roads, railways, buildings, and mines. They are mainly used for shoveling materials such as soil and sand, and can also be used for light shoveling operations on ore and hard soil. There are two types of loaders, hydraulic and mechanical. Hydraulic loaders are widely used in various fields because of their good mobility and flexibility. However, hydraulic loaders also have many shortcomings and shortcomings. First of all, hydraulic components require high machining accuracy. , manufacturing is more difficult, which increases the cost of the entire loader. Secondly, the m...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of multi-link reloading mechanism, which should first meet the operation requirements of the loader, and has the advantages of large load capacity and good force of the hydraulic loader, and overcomes the high maintenance cost and insufficient response of the traditional hydraulic excavator At the same time, it is also necessary to avoid the disadvantages of singular configuration of the tie rod, rocker arm and first connecting rod when the bucket is close to or in the limit configuration, so as to improve the load capacity and reliability of the electric loading mechanism
