According to the transmission structure of the shot blasting machine, a mounting structure of the transmission shaft is changed, and the bearing is arranged on the outer side of the chain wheel, so that the bearing cannot be abraded by the steel shots any more; meanwhile, a distance from the chain wheel to the cover plate is lengthened, and the scraper blade structure is additionally arranged at the middle part; the scraper blades rotate along with the transmission shaft to clear away the steel shots leaking from the holes in the cover plate, so that the bearing can be further protected. According to the transmission structure disclosed by the utility model, the service life of the bearing is greatly prolonged, and the production efficiency is improved.
Description
Technical field
The utility model belongs to machine design and manufacture field, especially belongs to Casting Equipment of Machine field, particularly a kind of shot-blasting machine drive mechanism.
Background technology
In Foundry Production scale removal process, for obtaining the foundry goods of any surface finish, conventionally must adopt shot-blasting machine to carry out shot blasting on surface processing to foundry goods.When shot-blasting machine is worked, by chain, affect sprocket rotation, sprocket wheel drives augur, and recycling exactly of shot carried by the blade screw rotation of auger conveyor.Existing shot-blasting machine is because the bearing with spherical outside surface position of auger conveyor is near ball blast pusher side, shot is easy to spill and enter bearing with spherical outside surface from the mesopore of shot-blasting machine cover plate in course of conveying, cause bearing with spherical outside surface quick abrasion, change frequently, cost of idleness, the replacing of bearing with spherical outside surface is lost time again, waste of manpower.
Summary of the invention
The utility model discloses a kind of shot-blasting machine drive mechanism according to the deficiencies in the prior art.The utility model object is to provide a kind of by changing drive mechanism, reset bearing with spherical outside surface position and increasing the scraper plate of clearing up shot, to reduce the wearing and tearing of shot to bearing with spherical outside surface, thereby realize the service life that extends bearing with spherical outside surface, reduce the wastage, cost-saving new shot-blasting machine drive mechanism.
The utility model is achieved through the following technical solutions:
Shot-blasting machine drive mechanism, comprise by shot-blasting machine cover plate opening and stretch into the power transmission shaft that shot-blasting machine inner chamber carries out shot conveying, it is characterized in that: the outer end portion that described power transmission shaft is positioned at shot-blasting machine cover plate is fixedly installed scraper plate and sprocket wheel successively, and power transmission shaft end is fixed by bearing and supporter.
Described bearing is arranged at supporter outside and fixes by bearing block and supporter.
Described power transmission shaft and shot-blasting machine cover plate and supporter are matched in clearance.
Above-mentioned scraper plate has a plurality of and is fixedly installed around the even interval of axle, scrapes board plane and arranges vertically.
Described shot-blasting machine cover plate is connected and fixed by bolt and shot-blasting machine wallboard.
The preferred bearing of the utility model adopts bearing with spherical outside surface, can further play aligning stabilization.
For stablizing sprocket wheel and bearing, between transmission shafts surface, sprocket wheel and bearing, be provided with distance bushing.
Shot-blasting machine, when work, affects sprocket rotation by chain, by chain wheel drive power transmission shaft, is rotated, and power transmission shaft drives auger blade to rotate, and the shot after shot-peening is passed by the helical rotation of blade, is delivered to storage place and again recycles.
The utility model helpfulness: the utility model has changed the mounting structure of power transmission shaft, during installation, is arranged on sprocket wheel outside by bearing, and bearing is no longer subject to the wearing and tearing of shot; Meanwhile, the distance that chain takes turns to cover plate also lengthens, and centre increases blade structure again.During work, scraper plate rotates with power transmission shaft, and the shot that cleaning spills from cover plate perforate, further protects bearing.The utility model structure has increased substantially the service life of bearing, has improved production efficiency.

The specific embodiment
Below by embodiment, the utility model is conducted further description; the present embodiment is only for being further detailed the utility model; but can not be interpreted as the restriction to the utility model protection domain, those skilled in the art makes some nonessential improvement according to content of the present utility model and adjustment belongs to the scope that the utility model is protected.
In conjunction with Fig. 1 to Fig. 5.
As shown in the figure, shot-blasting machine transmission shaft structure, comprises shot-blasting machine wallboard 01, shot-blasting machine cover plate 02, power transmission shaft 03, screw rod 04, sprocket wheel 05, flat key 06, distance bushing 07, supporter 08, bearing block 09, bearing 10, scraper plate 11, perforate 12, keyway 13.
Shot-blasting machine, when work, affects sprocket wheel 05 to rotate by chain, by sprocket wheel 05, drives power transmission shaft 03 to rotate, and power transmission shaft 03 drives auger blade to rotate, and the shot after shot-peening is passed by the helical rotation of blade, is delivered to storage place and again recycles.
Fig. 6 and Fig. 7 are existing transmission shaft structures, and as shown in the figure, bearing 10 coordinates with bearing block 09, and the internal diameter of bearing 10 coordinates with existing power transmission shaft 14, and bearing block 09 use hex screw is locked on shot-blasting machine cover plate 02; Existing power transmission shaft 14, bearing 10 and bearing block 09 carry out axial location by shot-blasting machine cover plate 02; Back-up ring 15 is locked at existing power transmission shaft 14 end faces by hex screw, prevents outer the moving of existing sprocket wheel 16.
Because bearing 10 is near shot-blasting machine cover plate 02, in shot-blasting machine when work,, shot is easy to spill and enter bearing 10 and produce wearing and tearing from 02 perforate 12 of shot-blasting machine cover plate.
