Abstract

The utility model discloses a loader vertical-lifting discharge-working device which comprises a steady rest (1), a moveable arm (2), a moveable arm hydro-cylinder (3), a bucket (4), and a bucket turnover hydro-cylinder (5). The utility model is characterized in that the front end of the moveable arm (2) is connected with the bottom of the bucket (4), the front end of the moveable arm hydro-cylinder (3) is connected with the middle portion of the moveable arm (2), an upper rotary handle (11) is arranged on the upper portion of the steady rest (1), the rear end of the moveable arm (2) is provided with a toggle rod (12), and the middle portion of the steady rest (1) is provided with a lower rotary handle (14) for leading the upper and the lower rotary handles (11, 14) and the upper section of the toggle rod (12) to form a four link mechanism. In the working device, because the moveable arm can not only rotate, but also can move in parallel for leading the orbit of the bucket to reach the purpose of vertical lifting, the working efficiency of the loader is enhanced, the rising height and the discharge distance of the working mechanism are also enlarged, the structure is compact, and the operation is stable. The utility model is particularly applicable to small-sized loaders.

Description

Loader vertical lift discharging equipment

Technical field

The utility model relates to a kind of improvement of working device of loader, specifically a kind of loader vertical lift discharging equipment.

Background technology

The equipment of loader is a key mechanism of finishing handling operation, and its form of structure can be directly connected to the operating efficiency and the economic indicator of loader. is present; The equipment of loading machine mainly contains swing arm; Connecting rod; Rocking arm; The scraper bowl overturning oil cylinder; Boom cylinder; Fixed support consists of; Fixed support is fixed on the car body; For small sized loader; The rear side that is fixed on the car front axle that fixed support also has; The rear end of swing arm is connected with fixed support by the jointed shaft of fixed support upper end; Appropriate location at swing arm is connected fixed support with boom cylinder with swing arm; In the equipment lifting process; Because the seat end of swing arm is for rotating along the axle that is fixedly hinged; Under the effect of boom cylinder expansion link; The front jointed shaft of swing arm and the lifting running orbit of scraper bowl are an arc; This arching trajectory is fixedly hinged axle as the center of circle take the seat end of swing arm; Because the seat end jointed shaft of swing arm is immovable; So this arching trajectory is also fixed; The equipment of this kind structure has the following disadvantages: the one, in order to enlarge the scope of activities of swing arm; Its swing arm need to be done very longly; And when droping to the bottom; It is long that the front jointed shaft of swing arm stretches out the distance of frame; So that complete machine is longer, affect flexibility and the stability of equipment; The 2nd, when scraper bowl rises to swing arm from horizontal level to the extreme higher position, the preceding jointed shaft of swing arm and scraper bowl have one section retraction distance along arching trajectory, so the handling distance of loader is diminished, reduced the operating efficiency of working device of loader, influenced lifting height and distance, it is more obvious that this shortcoming shows on small sized loader.

Summary of the invention

The purpose of this utility model is to provide a kind of above the deficiencies in the prior art that overcome, make the equipment compact conformation of loader, it in uphill process vertical operation, make its high efficiency, and can improve the loader vertical lift discharging equipment of lifting height and discharging distance, be specially adapted to middle-size and small-size loader.

For reaching above purpose, the technical scheme that the utility model adopted is: this loader vertical lift discharging equipment, by fixed support, swing arm, boom cylinder, scraper bowl, the scraper bowl overturning oil cylinder constitutes, the front end of swing arm is connected the bottom of scraper bowl by scraper bowl bottom-hinged axle, the front end of boom cylinder expansion link is connected the middle part of swing arm by swing arm middle part jointed shaft, the expansion link front end of scraper bowl overturning oil cylinder is connected with the upset connecting rod of scraper bowl rear side by the jointed shaft of upset rod rear end, it is characterized in that the jointed shaft by the fixed support upper end connects handler on support bracket fastened top, establish fixing poke rod in the rear end of swing arm, the turning cylinder that the outer end of last handler is connected with last handler by poke rod and the upper end of poke rod are connected, set handler at support bracket fastened middle part, the turning cylinder that the outer end of following handler is connected with following handler by poke rod and the lower end of poke rod are connected, make, form quadric chain between following handler and poke rod and the support bracket fastened epimere, the jointed shaft at the turning cylinder middle part that the base of scraper bowl overturning oil cylinder is connected with following handler by poke rod is fixed on the middle part of the turning cylinder that poke rod is connected with following handler, when the expansion link of boom cylinder outwards stretches, the front end of swing arm begins to rise, meanwhile, rotate the swing arm bottom, the drive poke rod rotates counterclockwise, poke rod is stirred handler and is clockwise rotated, when the uphill process of swing arm from horizontal level to the extreme higher position, last handler upwards clockwise rotates, meanwhile spur poke rod, poke rod spurs swing arm again and moves up, make scraper bowl in rising to the process of extreme higher position, move forward simultaneously, eliminate the retraction track of scraper bowl, keep straight line to rise.The utility model is also implemented by following measure: establish fixed head in support bracket fastened inboard, establish the turning cylinder of boom cylinder in the inner of fixed head, the base of boom cylinder is fixed on the turning cylinder of boom cylinder, and the base of boom cylinder also can be fixed on the car body; Described swing arm is established left and right two, its front end is fixed on the left and right end of scraper bowl bottom respectively by left and right scraper bowl bottom-hinged axle, corresponding boom cylinder is also established left and right two, its base is separately fixed at the left and right end of the turning cylinder of boom cylinder, thereby realize the left and right end of scraper bowl is exerted oneself simultaneously, make the scraper bowl lifting stable, firmly homogeneous; Described poke rod also is that triangle is tabular, and to increase the intensity of poke rod, poke rod can be manufactured in aggregates with swing arm; The fixed head of described fixed support inboard is that triangle is tabular, and the interior angle of its fixed head stretches out, and the base of fixed head and support bracket fastened inner edge are welded as a whole; The two ends of the turning cylinder that described poke rod is connected with last handler are separately fixed at left and right upper end of going up handler; The two ends of the turning cylinder that described poke rod is connected with following handler are separately fixed at the left and right upper end of handler down, also establish the welding fixed head in the left and right upper end of handler down, to increase resistance to overturning.When using the utility model, need support bracket fastened bottom is fixed on the front axle of loader, or the front side of front axle.

The beneficial effects of the utility model are: compare with employed equipment on the present loader, because swing arm existing rotation in lifting process, translation is arranged again, make the running orbit of scraper bowl reach the purpose of vertical lift, so improved the operating efficiency of loader, the lifting height of its operating mechanism and discharging distance have also obtained expansion, and compact conformation, stable, are specially adapted to small sized loader.
