Abstract
The utility model discloses a set of novel screw auger, which can serve as the auger conveying device body of a harvester or other mechanical equipment. The novel screw auger comprises a casing and an auger device installed in the casing; the auger device comprises an intermediate transmission shaft and an auger blade welded on the transmission shaft; the auger blade is formed by unit body blades which are combined and welded together; and the thickness of the material at the external edge line part of the auger blade is larger than that of the material at the internal edge line part, so that not only the wear resistance of the auger blade can be obviously improved and the service life can be prolonged, but also the transmission efficiency of the auger blade can be improved, the operating characteristic of the auger blade can be further improved, simultaneously the production process of the auger blade can be simplified, and the novel screw auger facilitates the reduction of the production cost. The novel screw auger has the characteristics of good wear resistant property of the auger blade, long service life, high transmission efficiency, reliable operating performance, and simple and reasonable production process, and is suitable for being applied to the auger conveying devices of various combine harvesters and other mechanical equipment.
Description
Technical field
The novel spiral screw feeder of one cover is adapted to do to carry screw feeder device usefulness on field machines such as combination machine, also can be used as on all kinds of engineering mechanical devices such as food machinery and vehicle for construction and makes spiral screw feeder driving device.
Background technology
On the existing spiral screw feeder, the design of screw feeder blade mainly contains two kinds: a kind of is to adopt the cast form of whole screw feeder blade, convenient and avoid foundry defect to occur for molding, must adopt the design plan of the material thickness of screw feeder blade inner edge blade tip ridge part greater than the material thickness of its outer edge line part, during the work of screw feeder device, the fret wear amount of outer edge line part is far longer than the inner edge blade tip ridge part, make the material thickness of outer edge line part thinner, cause spiral screw feeder device to lose efficacy in advance, two kinds is that the screw feeder blade adopts strip material integral body to draw to be rolled into shape, draw and be rolled in the shape process because the amount of tension of outer edge line part material is far longer than the material of inner edge blade tip ridge part, the material thickness of the material thickness of screw feeder blade inner edge blade tip ridge part must be caused, failure phenomenon in advance will be caused equally greater than its outer edge line part.
Summary of the invention
The purpose of this utility model provides the novel spiral screw feeder of a cover, accomplish that novel screw feeder blade can adopt cell cube blade shaping back Combination Welding to form whole screw feeder blade, and the material thickness of the outer edge line of screw feeder blade part is greater than the material thickness of inner edges line part, can obviously increase the resistance to abrasion of Strong screw feeder blade, prolong its service life, help improving the driving efficiency of screw feeder blade again, further improve the serviceability of screw feeder blade, simplified the production technology of screw feeder blade simultaneously, helped reducing production costs.
The core of technical scheme is by designing the novel spiral screw feeder of a cover, be applied on the screw feeder device of reaper and other mechanical equipment, it comprises housing and is installed in the interior screw feeder device of housing, the screw feeder device is made up of tween drive spindle and the screw feeder blade that is welded on the transmission shaft, the screw feeder blade adopts cell cube blade combination welding forming, the material thickness of the outer edge line part of screw feeder blade is greater than the material thickness of inner edges line part, and they form novel spiral screw feeder device jointly.
The material thickness of its outer edge line part of the screw feeder blade in the utility model is greater than the material thickness of inner edges line part, can obviously increase the resistance to abrasion of Strong screw feeder blade, prolong its service life, help improving the driving efficiency of screw feeder blade again, further improve the serviceability of screw feeder blade, simplified the production technology of screw feeder blade simultaneously, helped reducing production costs.
Compared with the prior art, characteristics of the present utility model are that the wear resisting property of screw feeder blade is good, long service life, the driving efficiency height, reliable working performance, the production process advantages of simple is applicable on the screw feeder feedway of various reapers and other mechanical equipment and uses.
The utility model both had been adapted to do to carry screw feeder apparatus body design plan to use on field machines such as various reapers, also can be applicable to other machinery, use as making spiral screw feeder driving device on all kinds of engineering mechanical devices such as agricultrue sideline production processing machinery, constructional engineering machinery, textile machine, traffic machinery.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further: as shown in Figure 1, 2, 3, novel spiral screw feeder is installed in the housing 1 of feedway, it comprises housing 1 and the screw feeder device that is installed in the housing 1, the screw feeder device is made up of tween drive spindle 3 and the screw feeder blade 4 that is welded on the transmission shaft 3, Combination Welding formed after screw feeder blade 4 adopted cell cube blade 2 to be shaped, after cell cube blade 2 is shaped, the material thickness of the outer edge line part 5 of screw feeder blade 4 is greater than the material thickness of inner edges line part 6, and they form novel spiral screw feeder device jointly.
Principle of work is as follows: when spiral screw feeder feedway rotates the beginning normal operation, produce friction between material that is transferred and the screw feeder blade 4, make 4 wearing and tearing of screw feeder blade, wherein the abrasion loss of the outer edge line part 5 of linear velocity maximum is far longer than the fret wear amount of inner edge blade tip ridge part 6, the size of screw feeder blade 4 abrasion losies from outside to inside, present the descending rule that gradually changes, consider the above Changing Pattern of abrasion loss, Combination Welding formed after screw feeder blade 4 in the novel spiral screw feeder device adopted cell cube blade 2 to be shaped, after cell cube blade 2 is shaped, because the material extending amount of inner edge blade tip ridge part 6 is far longer than the material extending amount of its outer edge line part 5 in the forming process, the material thickness of outer edge line part 5 that can ensure screw feeder blade 4 is greater than the material thickness of inner edges line part 6, the wear resisting property of outer edge line part 5 materials is significantly improved, more reasonable with the work life coupling of inner edge blade tip ridge part 6, and welding forming helps further improving wear resisting property, the spiral screw feeder device overall work life-span is improved significantly, outer thick interior slim screw feeder blade 4 in the novel spiral screw feeder device, make the screw feeder device in the process that transmits material, the axial active component of 4 pairs of material application forces of screw feeder blade strengthens, radially active component reduces, improved the mass transport efficient of screw feeder blade 4, make its not only reliable working performance, driving efficiency is also improved synchronously.
What deserves to be mentioned is that the utility model can be used as a cover independent device and is applied in other all kinds of mechanical transmission systems, it is simple in structure, reliable working performance, applied range.
