Abstract
The utility model relates to a material conveying device, particularly to an improved structured of an auger material conveying device. The material conveying device comprises a conveying pipe, auger vanes which are arranged in the conveying pipe and actuating shafts which are connected fixedly with the auger vanes. Two adjacent actuating shafts are respectively connected with the two ends of a connection shaft; the connection shaft is provided with a bearing which is installed in a sleeve; a bearing radial plate is fixedly arranged between the sleeve and the inner wall of the conveying pipe. The auger vanes can not rub the conveying pipe because the auger is too long, thereby prolonging the service life and being suitable for long-distance material conveying.
Description
Technical field
The utility model relates to a kind of material transfer equipment, relates in particular to the improvement of screw feeder feeding device structure.
Background technology
Screw feeder is widely used in the conveying of particulate material and powder because of its applied range, simple structure, advantage such as not fragile, easy to maintenance, with low cost.Present screw feeder is made of conveying pipeline and the spiral vane that is installed in the axle drive shaft in the conveying pipeline and is fixed on the axle drive shaft outside face.When the length of this screw feeder longer, as reach about 10 meters, screw feeder is horizontal or during obliquity, deadweight because of axle drive shaft and blade, make axle drive shaft generation deformation to cause blade to contact, more serious friction drag takes place during work with conveying pipeline, both influence screw feeder work velocity of rotation, reduced the work efficiency of screw feeder; Send ear-piercing frictional noise again, shorten the service life of screw feeder greatly.On the other hand, when screw feeder was carried paddy, corn, wheat and other particulate material, particulate material was pulverized in friction place of blade and conveying pipeline easily, and the quality of material is descended; And when carrying harder particulate material such as coal, friction place is easy to take place stuck phenomenon, even causes the accident.This still there is not at present effective solution.
The utility model content
Technical problem to be solved in the utility model provides a kind of screw feeder that can fail material at a distance, and no matter how long screw feeder has, is operated in which kind of position, and the blade of screw feeder can not produce friction with the conveying pipeline direct contact.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: the screw feeder that can fail material at a distance, comprise conveying pipeline, be positioned at the screw feeder blade of this conveying pipeline and the axle drive shaft of affixed screw feeder blade, two adjacent axle drive shafts are captiveed joint with the two ends of adapter shaft respectively, on this adapter shaft bearing is housed, this bearing installation is installed with the supporting disc between the inwall of this sleeve and described conveying pipeline in sleeve.
After adopting said structure, disc, sleeve, bearing are supported on adapter shaft on the axial location of axle drive shaft of screw feeder, and adapter shaft is captiveed joint with two adjacent axle drive shafts, so deformation can not take place by the disc support in the axle drive shaft of screw feeder during work, thereby the screw feeder blade not can with conveying pipeline generation mechanical friction, prolonged service life of screw feeder greatly.On the other hand,, improved the work efficiency of screw feeder, guaranteed the quality of convey materials because the normal operation of screw feeder has reduced the work capacity that screw feeder keeps in repair.
A kind of preferred implementation method of the utility model, described bearing is a needle bearing.
Another preferred implementation method of the utility model, described bearing is a ball bearing of main shaft.
The another kind of preferred implementation method of the utility model, described bearing is a plain bearing.
The further implementation method of the utility model, described disc are one to have the back plate in some holes.
The further implementation method of the utility model leaves the gap between described each disc.
The further implementation method of the utility model, the rotation direction of described disc is consistent with the rotation direction of blade.
The further implementation method of the utility model, seal ring is equipped with at the two ends of described bearing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the structural representation that the utility model can be failed the embodiment of the screw feeder of expecting at a distance.
The specific embodiment
Among Fig. 1, the axle drive shaft 2 of screw feeder is a tubular structure, the outside face of axle drive shaft 2 is welded with the screw feeder blade 1 that distributes along axle drive shaft 2 spirals, insert respectively in the adjacent tubular drive shaft 2 at the two ends of adapter shaft 3, and by bolt, nut is fixed, and needle bearing 4 is installed on the adapter shaft 3, and the outside face of needle bearing 4 is equipped with sleeve 5.Be welded with three disc 6 that distribute along the radial symmetry of adapter shaft 3 on the sleeve 5, gapped between the disc 6, the rotation direction of the three disc 6 all rotation direction with screw feeder blade 1 is consistent.The top of disc 6 is welded on the supporting plate 7, supporting plate 7 is by bolt, nut is fixedly connected on the inwall of conveying pipeline 8, for preventing that the powder of expecting in the defeated material process from entering needle bearing 4, at the two ends of needle bearing 4 seal ring 9 is housed, when the screw feeder normal operation, screw feeder blade 1 will expect to promote forward, when arriving blade 1 terminal, arrive the top of another section screw feeder by the gap of disc 6, defeated material can normally be carried out, the adapter shaft 3 of captiveing joint with the axle drive shaft 2 of screw feeder is by needle bearing 4, sleeve 5, disc 6 is fixed in the conveying pipeline 8, the deformation that makes axle drive shaft 2 take place is very little, thereby screw feeder blade 1 do not contact with the inwall of conveying pipeline 8, thereby guarantees the screw feeder normal operation.
When making the screw feeder blade, annular section with circular sheet cuts a slit between interior bore edges and outer circular edge earlier, and the slit drawn back vertically, each having been cut the annulus thin plate that draws back is enclosed within on the axle drive shaft 2 again, order is got up two adjacent annulus light gauge welding then, become as a whole, each annulus thin plate that connects together along axle drive shaft 2 axial tensions firm welding again, treat that all annulus thin plates are on the axle drive shaft 2 twist behind the rectangular distribution, all annulus light gauge welding are fixed on the outside face of axle drive shaft 2, become the bolt shape screw feeder blade of screw feeder.
It below only is preferred implementation of the present utility model.Described bearing is not limited to needle bearing, can also adopt antifriction-bearing box and plain bearings such as ball bearing of main shaft; Described disc is not limited to be fixed on the inwall of conveying pipeline by supporting plate, can also connect by the spiral shell mosquito directly to be fixed on the inwall of conveying pipeline; The quantity of described disc is not limited to three; can also be two, four, five that install along adapter shaft 3 radial symmetry ... or the like; described disc can also be the back plate that a slice has some holes, and these distortion and improvement all should be considered as belonging to protection domain of the present utility model.
