Abstract
The utility model relates to a working mechanism for a loader, which is capable of setting flat automatically. The working mechanism comprises a front frame, a movable arm, a rocker, a bucket, a connecting rod, a lifting oil cylinder and a bucket rotating oil cylinder. The ratio of the distances between the hinge joints of the front frame, the movable arm, the rocker, the bucket, the connecting rod, the lifting oil cylinder and the bucket rotating oil cylinder is within a certain range. In each operation cycle of the loader, during the lifting process of the movable arm, the movable arm enables the bucket to maintain the translation state, thereby improving the translation performance during the lifting process, effectively preventing the material from scatting when the bucket is lifted and ensuring the cleanness of the working environment of the loader and improving operation safety. Meanwhile, when the movable arm descends, the angle of the bucket can be adjusted automatically through the rod system; after being unloaded, the bucket can be set flat automatically at minus 3degrees to minus 6 degrees; and the load working device can be reset to the previous excavating state, thus saving power, avoiding the repeated operations due to that the bucket is not restored precisely, reducing the work intensity of the operators and improving the work performance and work efficiency of the loader.
Description
Technical field
The utility model relates to the loader operating mechanism that a kind of energy realization is set level automatically, belongs to the loader technical field.
Background technology
Working device of loader is by hydraulic-driven and the spacing multi-connecting-rod mechanism that finishes handling operation, is one of critical component of loader, and the height of its design level directly influences service behaviour, operating efficiency and the economic indicator of loader.Present working device of loader generally adopts the counter-rotating six bar mechanism that is made of front frame, swing arm, rocking arm, scraper bowl, connecting rod, elevating ram and rotary ink tank.The counter-rotating six bar mechanism has advantages such as simple in structure, that digging force is big, but because the size of each rod member fails to reach more rational proportion configuration, in the moved arm lifting process, scraper bowl needs by oil cylinder control to reach the translation state.In addition, when swing arm dropped to ground location, this scraper bowl also needed to control to return to last spading state by oil cylinder, has not only increased labor intensity of operating personnel, and has influenced operating efficiency.
Summary of the invention
The purpose of this utility model provides a kind of loader operating mechanism set level automatically of realizing, under the prerequisite that guarantees former digging force, improves the lifting translation, and scraper bowl is set level automatically return to the spading operating position.
The utility model is that the technical scheme that achieves the above object is: the loading machine operating mechanism that a kind of energy realization is set level automatically; Comprise front frame; Swing arm; Rocking arm; Scraper bowl; Connecting rod; Elevating ram and rotary ink tank; Two swing arm rear portions are hinged on respectively the both sides of front frame; The front end of swing arm and scraper bowl bottom-hinged; The rear end of two elevating rams is hinged on respectively on the front frame; The tailpiece of the piston rod of elevating ram is hinged on the bottom of swing arm; Rocking arm is hinged on the intermediate support of two swing arms; The rear end of rotary ink tank is hinged on the front frame; The tailpiece of the piston rod of rotary ink tank is hinged on the top of rocking arm; The connecting rod two ends respectively with the lower hinge of scraper bowl bottom and rocking arm; It is characterized in that: it is characterized in that: described swing arm and the scraper bowl pin joint ratio of two pin joint length L to the distance R 1 between rocking arm and the intermediate support pin joint and the swing arm is 0.35～0.46; Swing arm and the scraper bowl pin joint ratio of two pin joint length L to the distance R 2 between scraper bowl and the connecting rod hinge point and the swing arm is 0.13～0.14; Distance R 3 between connecting rod two pin joints is 0.18～0.24 with the ratio of swing arm front and back two pin joint length L; Rocking arm lower link point ratio of two pin joint length L to the distance R 4 between rocking arm and the intermediate support pin joint and the swing arm is 0.30～0.39; Rocking arm upper link point ratio of two pin joint length L to the distance R 5 between rocking arm and the intermediate support pin joint and the swing arm is 0.23～0.39; The ratio of two pin joint length L is 0.66～0.80 before and after distance R 6 between swing arm upper link point and the intermediate support hinge and the swing arm, and swing arm upper link point ratio of two pin joint length L to the distance R 7 between the rear end pin joint of rotary ink tank and the swing arm is 0.12～0.14.
The utility model is under the constant situation of the digging force of the type product that maintains the standard and fuselage shape thereof, functional dimension, determine the size of counter-rotating six each rod member of connecting rod operating mechanism by optimal design, make loader in each work cycle, swing arm can make scraper bowl keep the translation state in the lifting process, improved the translation of lifting process, prevent material shedding in scraper bowl lifting process effectively, guaranteed the clean and tidy safety that also can improve operation of loader working environment.Simultaneously, in swing arm decline process, automatically regulate the angle of scraper bowl by this leverage, can realize after the unloading being leveled to-3 °～-6 ° automatically, will load equipment and return to last spading state, both save power consumption, avoided again because of the scraper bowl inaccurate repeatable operation that resets, thereby reduced operating personnel's number of operations, reduced labor intensity of operating personnel, improved the service behaviour and the operating efficiency of loader.
