Abstract
The utility model relates to a working mechanism of a side-dumping rock loader, which mainly solves the problems of limited turnover angle of a bucket, insufficient lifting height of the bucket and unstable waste rock conveying of the existing working mechanism of the side-duping rock loader. The working mechanism is characterized in that a bucket seat (3) is also articulated with a pull rod (4); the other end of the pull rod (4) is articulated with a rocker arm (5); the other end of the rocker arm (5) is articulated with a piston on a skip bucket oil cylinder (6); the rocker arm (5) is a crank arm, and the bending part is articulated with a crank (9); and the other end of the crank (9) is articulated on a large arm (7). The working mechanism has the advantages that the turnover angle of the bucket is increased, the lifting height of the bucket is improved, and the loading and unloading operation can be stably completed when the bucket moves.
Description
Technical field
The utility model relates to the operating mechanism of dirt loader in the rock roadway in coal mine mechanized, is specifically related to a kind of side unloading rock loader operating mechanism.
Background technology
The colliery is the indispensability equipment of rock roadway in coal mine machanized line with side unloading rock loader, is mainly used in tunnelling, river stope shipment rock and mineral.Because of the electric fixtures of this machine is a flame-proof type, so can be used for having operation in the mine of imflammable gas.And side unloading rock loader is as a kind of colliery trackless loading machine, compares with other loading machine to have the productivity ratio height, and bucket capacity is big, and insertion force is big, can be to the characteristics of row mine car unloading; The adapted leather belt reshipment machine uses the following mine car transportation of 1.5t can reach continuous shipment, gives full play to the high production rate effect of side unloading rock loader; And side unloading rock loader is except that loading and unloading, and can assist the operation of finishing other operations, as the clear end, tunnel, and work plane short distance haul, lifting as the support work platform etc., thereby significantly reduces labor strength, improves the mechanization level of tunnelling; Also the section muck helps civilized construction entirely, and power type does not have exhaust emission, and noise is low, and is safe and reliable, can easily be supporting with drill carriage or other tunnel face machinery, form efficient machanized line.Yet owing to the structure design reason, operating mechanism's scraper bowl flip angle of existing side unloading rock loader is little, and it is low to cause scraper bowl to fill rate, and living rate is low; Big arm stretches out, and can not keep strict translation in the process of scraper bowl lifting, spreads cash easily, causes the accident; The scraper bowl lift height is lower, and is unrestrained easily to the mine car outside during toward mine car unloading spoil.
Summary of the invention
In order to increase the scraper bowl flip angle, improve the scraper bowl lift height, make that to produce bucket steady when mobile, the utility model provides a kind of side unloading rock loader operating mechanism.This operating mechanism has increased the scraper bowl flip angle, has improved the scraper bowl lift height, and makes and produce bucket and steadily finish loading and unloading when mobile.
The technical solution of the utility model is: a kind of side unloading rock loader operating mechanism, comprise scraper bowl, side dumping oil cylinder, scraper bowl seat, dump ram, big arm and big arm oil cylinder, wherein the side dumping oil cylinder is fixed on the scraper bowl, scraper bowl is hinged on the scraper bowl seat by bearing pin, big arm also is hinged on the scraper bowl seat, and big arm oil cylinder and dump ram are hinged on the big arm; And the other end of big arm oil cylinder, big arm and dump ram all is hinged on the body, wherein, also connects hinged pull bar on the scraper bowl seat, the hinged rocking arm of the other end of pull bar, the other end of rocking arm and the piston hinge on the dump ram; And rocking arm is for cranking arm, and in the knee hinged crank, the other end of crank is hinged on the big arm.
The beneficial effects of the utility model are: owing to increased pull bar and rocking arm between the product bucket seat of former mechanism and big arm, make the rotating bucket angle become big, the amount of filling raising; Translation is lifted bucket and is not spread cash, job safety; Side dumping simultaneously and front dump, load the collection down-hole and bulk cargo is heaped and the whole body; Planted agent's degree of depth increases increased functionality.
Description of drawings
Fig. 1 is the structural representation of side unloading rock loader operating mechanism in the prior art;
Fig. 2 is a structural representation of the present utility model.
The 1-scraper bowl, 2-side dumping oil cylinder, 3-scraper bowl seat, 4-pull bar, 5-rocking arm, 6-dump ram, the big arm of 7-, the big arm oil cylinder of 8-, 9-crank.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing 2, this side unloading rock loader operating mechanism comprises scraper bowl 1, side dumping oil cylinder 2, scraper bowl seat 3, dump ram 6, big arm 7 and big arm oil cylinder 8, wherein side dumping oil cylinder 2 is fixed on the scraper bowl 1, scraper bowl 1 is hinged on the scraper bowl seat 3 by bearing pin, big arm 7 also is hinged on the scraper bowl seat 3, and big arm oil cylinder 8 and dump ram 6 are hinged on the big arm 7; And the other end of big arm oil cylinder 8, big arm 7 and dump ram 6 all is hinged on the body.In addition, on the basis of existing side unloading rock loader operating mechanism, improvements are: also connect hinged pull bar 4 on the scraper bowl seat 3, the hinged Rocker arm 5 of the other end of pull bar 4, the piston hinge on the other end of Rocker arm 5 and the dump ram 6; And Rocker arm 5 is for cranking arm, and in the Rocker arm 5 knee hinged crank 9, the other end of crank 9 is hinged on the big arm 7.
The course of action of this side unloading rock loader operating mechanism is as follows: at first, the whole reach of operating mechanism, dump ram 6 stretches out in the process of whole reach, produce 1 reach that struggles against by Rocker arm 5, pull bar 4 and 3 drives of product bucket seat, make scraper bowl 1 fill spoil, big then arm oil cylinder 8 stretches out, the scraper bowl 1 of filling spoil is steadily raised, the product of filling spoil 1 integral body that struggles against moves to the proper height and the position of unloading spoil, side dumping oil cylinder 2 stretches out or dump ram 6 withdrawals, make and produce the bucket inclination, work stone is unloaded to assigned address, begin next circulation then.Because this mechanism has increased pull bar 4 and Rocker arm 5 at the product bucket seat 3 of former mechanism shown in Figure 1 and big 7 on arm, compares with side unloading rock loader operating mechanism in the prior art, it is big that the rotational angle of scraper bowl 1 becomes, and dress cash amount improves; Translation is lifted bucket and is not spread cash, job safety; Side dumping simultaneously and front dump, load the collection down-hole and bulk cargo is heaped and the whole body; Planted agent's degree of depth increases increased functionality.
