An auger for easy welding

Abstract

The invention discloses an auger convenient in seaming and belongs to the field of augers for agricultural machinery, food machinery and building machinery. The auger comprises a first mounting plate and a second mounting plate which are fixed at one end of an auger shaft and arranged around the auger shaft in a crossed manner. Each of the first mounting plate and the second mounting plate is evenly provided with N mounting holes. A retaining ring is disposed at one end, away from the blades of the auger, of each of the first mounting plate and the second mounting plate. The axis of each retaining ring coincides with the axis of the auger shaft. The length of the first mounting plate equals to the diameter of corresponding retaining ring. The length of the second mounting plate is smaller than the diameter of the corresponding retaining ring. The width of the first mounting plate is larger than that of the second mounting plate. The auger has the advantages horizontal arrangement of the auger shaft is guaranteed by the crossed mounting plates, the mounting plates are designed according to welding clamps, the stability of the auger shaft is enhanced, and the welding quality of auger blades are increased.

Description

technical field [0001] The invention relates to an auger device used in agricultural machinery, food machinery or construction machinery, in particular to an auger which is convenient for welding. Background technique [0002] On the existing spiral auger, there are three main designs of the auger blade: one is to use the integral auger blade to form the casting, in order to facilitate the mold drawing and avoid casting defects, the material thickness of the inner edge line of the auger blade must be used The design scheme of the material thickness greater than the outer edge line part, when the auger device is working, the material wear amount of the outer edge line part is much larger than that of the inner edge line part, so that the material thickness of the outer edge line part is thinner, resulting in the spiral auger The device fails prematurely. The second is that the auger blade is formed by integral drawing and coiling of steel strip material. During the drawing an...

Problems solved by technology

[0005] Aiming at the problems of unreliable welding of existing auger blades, cracks, misalignment and other welding defects, the present invention provides an auger that is easy to weld, which ensures the horizontal placement of the auger shaft through cross-arranged mounting plates, And the mounting plate is designed according to the welding fixture to strengthen the stability of the auger shaft, thereby improving the welding quality of the auger blades
