Abstract
A connecting mechanism of a bucket rod and a bucket is characterized in that two surfaces on the inner sides of bucket shaft seats are respectively and fixedly provided with a wear-resisting mat, a pin shaft is arranged between the two shaft seats, the pin shafts on the inner side of the two shaft seats of the bucket are respectively and symmetrically provided with a shaft sleeve, a sealing ring is arranged between each wear-resisting mat and a flange surface of the shaft sleeve, the outer circle of each shaft sleeve is fixedly provided with a bucket rod, a bushing is arranged on the periphery of the outer circle of the pin shaft between the two bucket rods, two ends of the bushing are respectively and fixedly connected with the inner side surface of each bucket rod, a wool felt is filled in the space between the bushing and the pin shaft, the outer circle of the bushing is fixedly provided with an oil injection nozzle, lubricant is filled between the wool felts, the middle of the pin shaft is provided with a radial oil hole, the central part of the pin shaft is provided with an axial oil hole which penetrates the radial oil hole, and the pin shaft which is arranged on the shaft sleeve part is provided with an oil outlet hole which is communicated with the axial oil hole. The connecting mechanism has the advantages of high carrying capacity, good wear resistance and long service life.
Description
Technical field
The present invention relates to excavator, be specifically related to the bindiny mechanism of dipper and the scraper bowl of excavator, belong to the excavator technical field.
Background technology
At present, in the bindiny mechanism of the dipper of excavator and scraper bowl, between the end face that is hinged between dipper and the scraper bowl, the situation of serious wear usually occurs, the main cause that this thing happens is: 1, the material of hinged place is common mild steel or the ordinary construction steel of medium carbon steel class, and its abrasion resistance is relatively poor; 2, stressing conditions is complicated between the bonding surface that is hinged, and load is larger, and this wearing and tearing not only can reduce the application life of equipment, simultaneously, when wear extent is larger, just have the load that drives oil cylinder is strengthened, even can't work, to this, go back at present the reasonable solution of neither one.
Summary of the invention
The object of the invention is to: for existing defects in the bindiny mechanism of the dipper of existing excavator and scraper bowl, the invention provides a kind of novel dipper and the bindiny mechanism of scraper bowl, overcome the existing defects of bindiny mechanism of existing dipper and scraper bowl.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the bindiny mechanism of described a kind of dipper and scraper bowl, it is by axle bed, bearing pin, axle sleeve, sealing ring, dipper, sleeve, wool felt, pump nozzle, locking nut, wear-resistant pad forms, it is characterized in that: each fixes a wear-resistant pad on the two sides of scraper bowl axle bed inboard, between two axle beds of scraper bowl, a bearing pin is set, a locking nut is fixed in end installation at bearing pin, each arranges an axle sleeve symmetrically on the bearing pin of the inboard of two axle beds of scraper bowl, the flange face of described axle sleeve contacts with the inner side plane of wear-resistant pad, between the flange face of wear-resistant pad and axle sleeve, be provided with sealing ring, a dipper is fixed in cylindrical installation at each axle sleeve, a sleeve is set around the bearing pin cylindrical between two dippers, the medial surface of described sleeve two ends and dipper is connected and fixed, space-filling between sleeve and bearing pin has wool felt, a pump nozzle is fixed in cylindrical installation at sleeve, between wool felt, be marked with lubrication oil, centre at bearing pin is shaped with radial direction oil hole, be shaped with the axial oilhole that connects with radial direction oil hole in the centre of bearing pin, be shaped with the oil outlet that connects with axial oilhole at the bearing pin that is in the axle sleeve position.
Beneficial effect: among the present invention, owing to can store more lubrication oil in the wool felt in sleeve, lubrication oil is by radial direction oil hole, axially oilhole and oil outlet lead to the bonding surface between wear-resistant pad and the axle sleeve, simultaneously, because wear-resistant pad and axle sleeve can adopt high-abrasive material to make separately, has good lubricated lubricating condition in addition, so, not only can bear larger load, simultaneously, also have advantages of wear-resisting, so, the present invention has that supporting capacity is higher, anti-wear performance is better, the advantage that application life is long.
