Background technology
Existing loader mainly is the fluid pressure type transmission, has simple in structurely, in light weight, can realize advantages such as a lot of compound actions, is widely adopted.But hydraulic excavator is to be the medium of transferring power with hydraulic oil, and its startup is relatively poor, leak because of inner member wearing and tearing back produces easily, and the element that relates to is more, and the hydraulic oil of leakage can cause the pollution of environment.Phenomenons such as it is overheated to occur simultaneously, and it is unable to work.Along with the increase of loader function, its hydraulic system becomes increasingly complex, and the appearance of fault has more emergentness, disguise.
Though the fluid pressure type loader can be carried out various engineering actions neatly, because there are defectives such as hydraulic system component requirement height, life-span length, leakage of oil in it, so far remaining very stubborn problem of one of engineering machinery field, also is to fail the difficult problem that makes a breakthrough for a long time.
Summary of the invention
The purpose of this utility model provides a kind of planer multiple degree of freedom controllable loading mechanism, and it can overcome the fluid pressure type loader to Hydraulic Elements requirement height, easily produce the shortcoming that leakage of oil, reliability are difficult to guarantee.
The utility model achieves the above object by the following technical programs:
A kind of planer multiple degree of freedom controllable loading mechanism, comprise lifting mechanism, the scraper bowl switching mechanism, described lifting mechanism is made up of first driving lever, first follower lever, lift arm and frame, first driving lever, one end is hinged with first follower lever by the 5th fraising, and the other end is hinged on the frame by first, and the first follower lever other end is hinged with lift arm by the 6th fraising, lift arm one end is hinged on the frame by the 3rd, and the other end is hinged with scraper bowl by the 7th fraising.
Described scraper bowl switching mechanism is by second driving lever, second follower lever, first drive link, second drive link, the 3rd drive link, the 4th drive link, scraper bowl and frame connect to form, described second driving lever, one end is hinged with second follower lever by the 8th fraising, the other end is hinged on the frame by second, first drive link is respectively by the 12 fraising, the 9th fraising and the 11 fraising and second drive link, the 3rd drive link, the 4th drive link is hinged, first drive link and the 3rd drive link are hinged with second follower lever by the 9th fraising, the second drive link other end is hinged on the frame by the 4th, the 3rd drive link other end is hinged with lift arm by the tenth fraising, and the other end of the 4th drive link is hinged with scraper bowl by the 13 fraising.
Described first driving lever and second driving lever are respectively by first servomotor and the control of second servomotor.
Described planer multiple degree of freedom controllable loading mechanism is equipped with two servomotors.The location and the walking of functions such as frame itself can be installed in traditional loader and take back on the rubber-tyred or crawler type walking mechanism that changes platform, realizes loading, discharging and complete machine.
When loader mechanism carries out work,, the lift arm servomotor is controlled, made the front end of lift arm be implemented in working space interior lifting and reduction by controller according to the loader action request.In the rising of finishing lift arm and decline,, cooperate lift arm to realize the lifting and the rotary movement of scraper bowl by the servomotor of control scraper bowl switching mechanism.After the loading action was finished, lift arm promoted, and made the level of scraper bowl maintenance with respect to ground by the scraper bowl switching mechanism, and loader is transported to certain assigned address.During discharging, the scraper bowl switching mechanism reclaims, and the action of unloading is finished in the scraper bowl revolution.
Outstanding advantage of the present utility model is:
1, the scraper bowl switching mechanism has automatic horizontal adjusting and backspace rotating function.In the lift arm lifting process, can keep scraper bowl with respect to the level on ground and prevent owing to horizontal level is crossed in the revolution of scraper bowl.
2, owing to adopt outer revolute pair to drive, all servomotors all are installed on the frame, effectively reduce arm weight, improve the rate of loading.
3, two drive motors are computer-controlled servomotor, can realize the loading and the discharging action of loader mechanism by programming.
Plane of the present utility model loader mechanism can solve that the fluid pressure type loader is long to part requirement height, life-span, the problem of easy oil leakage, and complete machine structure is simply compact, and it is low that component are made processing request.
