Abstract
The invention provides a loader working device which comprises a movable arm, wherein the front end of the movable arm is connected with a bucket; a movable arm oil cylinder is arranged at the lower end of the rear side of the movable arm; a rotating bucket oil cylinder is arranged at the lower end of the front side of the movable arm; the rear end of the rotating bucket oil cylinder is connected with the movable arm through a rear pin shaft of the rotating bucket oil cylinder; and the front end of the rotating bucket oil cylinder is connected with the bucket through a front pin shaft of the rotating bucket oil cylinder. The movable arm comprises two movable arm plates, and the two movable arm plates are welded through enhanced round steel so as to form a box structure. When high-order unloading of a material needs to be carried out, the movable arm reaches the highest point under the lifting effect of the movable arm oil cylinder, and meanwhile, the rotating bucket oil cylinder shortens the stroke and drives the bucket to clockwise rotate around the movable arm, thereby realizing the unloading of the material at the highest point. The device provided by the invention overcomes the defects of the prior art, can greatly improve the visual field of a driver in operation, is compact in structure, high in strength and reliable in performance, reduces the quality of the complete machine, increases the payload and operating efficiency and lowers the manufacturing cost.
Description
Technical field
The present invention relates to a kind of working device of loader, belong to technical field of engineering machinery.
Background technology
Loader is one of main machine of engineering machinery, is widely used in each department of national economies such as building, mine, water power, highway, railway, harbour.Equipment is the important composition parts on loader, and the reasonability of equipment design directly affects the production efficiency, kinetic characteristic, application life etc. of loader.Although loader, through the development of decades, reaches its maturity, to the optimal design of equipment still tool be of great significance.
The structure of conventional load machine equipment as depicted in figs. 1 and 2, primarily of compositions such as traditional swing arm 1, rotary ink tank 2, rocking arm 3, pull bar 4, scraper bowl 5, boom cylinder 6, mobile beams 7.Scraper bowl 5, boom cylinder 6, rotary ink tank 2 are assembled into one respectively with traditional swing arm 1; rocking arm 3 middle-end and mobile beam 7 connect as one; rocking arm 3 front and back end connects as one with pull bar 4 and rotary ink tank 2 respectively, and the rear end of scraper bowl 5 and traditional swing arm 1 and pull bar 4 connect as one.When needing the high-order unloading carrying out material, tradition swing arm 1 is issued to peak at the castering action of boom cylinder 6, rotary ink tank 2 shortens stroke simultaneously, promote rocking arm 3 to turn clockwise around traditional swing arm 1, pull bar 4 makes scraper bowl 5 relatively traditional swing arm 1 inverse time flip an angle under rocking arm 3 acts on, thus realizes the unloading of material in highest order.Because rotary ink tank 2, rocking arm 3, pull bar 4, mobile beam 7 are all arranged in traditional swing arm 1 zone line, affect visual field during driver's operation.Rocking arm 3 and pull bar 4 are arranged in the narrow space between scraper bowl 5 and front frame, component easily occurs and mutually interferes.And traditional swing arm is all single plate structure, structural strength may Shortcomings.
Therefore, be necessary to improve and optimizate the structure of conventional load machine equipment.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of for loader can increase substantially driver's operation time the visual field, the equipment that alleviates overall mass, improve actual load and structural performance.
In order to solve the problems of the technologies described above, technical scheme of the present invention is to provide a kind of working device of loader, it is characterized in that: comprise swing arm, swing arm front end connects scraper bowl, boom cylinder is located at the rear side lower end of swing arm, rotary ink tank is located at the lower end, front side of swing arm, and rotary ink tank rear end is connected with swing arm by rotary ink tank rear pin shaft, and rotary ink tank front end is connected with scraper bowl by bearing pin before rotary ink tank.
Preferably, described swing arm comprises two blocks of swing arm plates, and the reinforcement round steel welding between two blocks of swing arm plates pass through, forms a box-structure.
Preferably, described boom cylinder and rotary ink tank are all located between described two blocks of swing arm plates.
Preferably, by the flexible upset realizing the relatively described swing arm of described scraper bowl of described rotary ink tank.
When needing the high-order unloading carrying out material, swing arm is issued to peak at the castering action of boom cylinder, and rotary ink tank shortens stroke simultaneously, and band scraper bowl moving arm turns clockwise, thus realizes the unloading of material in highest order.
Device provided by the invention overcomes the deficiencies in the prior art, significantly can improve visual field during driver's operation, and compact conformation, intensity are large, dependable performance, alleviate overall mass, improve actual load and operating efficiency, reduce manufacturing cost.

Detailed description of the invention
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The structural representation of the working device of loader that Fig. 3 provides for the present embodiment, eliminates the structure of mobile beam 7, rocking arm 3, pull bar 4, and rearranges the position of rotary ink tank 2, thus visual field when expanding operation; Reinforcement round steel 10 between being passed through by two blocks of swing arm plates is welded as box-structure, forms new swing arm 8, thus improves its structural strength.
Composition graphs 4, the working device of loader that the present embodiment provides is made up of bearing pin 9, reinforcement round steel 10, rotary ink tank rear pin shaft 11 etc. before rotary ink tank 2, scraper bowl 5, boom cylinder 6, swing arm 8, rotary ink tank.Boom cylinder 6, scraper bowl 5 are assembled into one respectively with swing arm 8, swing arm 8 front end connects scraper bowl 5, and boom cylinder 6 is arranged in the rear side lower end of swing arm 8; Rotary ink tank 2 is arranged in the lower end, front side of swing arm 8, and rotary ink tank 2 rear end is connected with swing arm 8 by rotary ink tank rear pin shaft 9, and rotary ink tank 2 front end is connected with scraper bowl 5 by bearing pin before rotary ink tank 11; Boom cylinder 6 and rotary ink tank 2 are arranged between two blocks of swing arm plates, by the flexible upset realizing the relative swing arm 8 of scraper bowl 5 of rotary ink tank 2.
When needing the high-order unloading carrying out material, new swing arm 8 is issued to peak at the castering action of boom cylinder 6, and rotary ink tank 2 shortens stroke simultaneously, and band scraper bowl 5 turns clockwise around new swing arm 8, thus realizes the unloading of material in highest order.
The Structure Comparison traditional structure that the present embodiment provides, eliminates rocking arm 3, pull bar 4, mobile beam 7, makes there is not any shelter between swing arm, drastically increases visual field during driver's operation, also save manufacturing cost.
