The object of the present invention is to provide a kind of one-dimensional rotation swing arm two-dimensional rotary scraper bowl space controllable-mechanism type loader, by controllable motor, driven, link transmission, each parts machining matching requirements are low, can effectively overcome the shortcomings such as hydraulic loader Hydraulic Elements requirement on machining accuracy is high, maintenance cost is high, reliability is difficult to ensure card, easy leakage of oil, can also fine solution plane loader can only realize the track output in plane, the problems such as the action underaction, the working space that cause are limited, inefficiency.
The present invention achieves the above object by the following technical programs:
A kind of one-dimensional rotation swing arm two-dimensional rotary scraper bowl space controllable-mechanism type loader, comprise car body, swing arm, scraper bowl, the first driving lever, the second driving lever, the 3rd driving lever, first connecting rod, second connecting rod, third connecting rod, the first servomotor, the second servomotor and the 3rd servomotor, its structure and connected mode are:
Swing arm one end is connected with car body by the first revolute pair, the other end is connected with scraper bowl by universal joint, first driving lever one end is connected with the first servomotor being cemented on car body by the second revolute pair, the other end is connected with first connecting rod by the 3rd revolute pair, and the first connecting rod other end is connected with swing arm by the 4th revolute pair.Second driving lever one end is connected with the second servomotor being cemented on car body by the 5th revolute pair, and the other end is connected with second connecting rod by the first spherical pair, and the second connecting rod other end is connected with scraper bowl by the second spherical pair.The 3rd driving lever one end is connected with the 3rd servomotor being cemented on car body by the 6th revolute pair, and the other end is connected with third connecting rod by the 3rd spherical pair, and the third connecting rod other end is connected with scraper bowl by the 4th spherical pair.
Outstanding advantages of the present invention is:
1, by controllable motor, driven, link transmission, each parts machining matching requirements are low, can effectively overcome the shortcomings such as hydraulic loader Hydraulic Elements requirement on machining accuracy is high, maintenance cost is high, reliability is difficult to ensure card, easy leakage of oil.
2, swing arm can be realized independently one-dimensional rotation, scraper bowl can be realized independently two-dimensional rotary, the motion of whole loading function implementation space three mobilities, mechanism's output trajectory is flexible, working space is large, operating efficiency is high, can be severe at environment, the construction site of narrow space and need to load fast, remove obstacles, smooth burst accident rescue site can bring into play better acting on.
