Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0024] Such as figure 2 As shown, a shaftless screw conveyor includes a motor 26, a first cylinder conveying cylinder 6, a second cylinder conveying cylinder 11, a first helical blade 5, a second helical blade 13, a feed bin 1, a blanking Case 16, mixing case 18. The output shaft of the motor 26 is connected with the input pulley 29 through the key 9, and the input pulley 29 is connected with the output pulley 8 through the V-belt, and the output pulley 8 is connected with the first cylinder conveying cylinder 6 through the key 27. The output pulley 8 is axially fixed on the first cylindrical conveying barrel 6 through the shaft shoulder and the bushing 7 , wherein the bushing 7 is fixed on the first cylindrical conveying barrel 6 by screws 28 . Using a V-belt as a tra...

Abstract

The invention provides a shaftless screw conveyor. The shaftless screw conveyor comprises a motor, a first cylinder conveying cylinder, a second cylinder conveying cylinder, spiral blades, a feed bin, a material discharge box and a material mixing box. One end of the first cylinder conveying cylinder is rotationally installed on one side of a discharge port of the feed bin, and the other end of the first cylinder conveying cylinder is fixedly connected with one end of the second cylinder conveying cylinder. The other end of the second cylinder conveying cylinder is rotationally installed on one side of a feed port of the material discharge box. The first spiral blade is fixedly connected to the inner wall face of the first cylinder conveying cylinder. The other end of the first spiral blade is fixedly connected with one end of the second spiral blade. The outer side face of the second spiral blade keeps being tangent to the inner wall face of the second cylinder conveying cylinder and is detachable. Because of the split structure of a conveying barrel, under the condition that the second spiral blade is damaged, the whole section of spiral blade does not need to be replaced, the use cost is saved, and replacement is easy.

Description

technical field [0001] The invention belongs to the field of transportation, in particular to a shaftless screw conveyor. Background technique [0002] The screw conveyor has the advantages of simple structure, low manufacturing cost, strong sealing, safe and convenient operation, etc. At present, shaftless screw conveyors are widely used in chemical industry, building materials, metallurgy, food and other departments, but compared with shafted screw pumps, due to the lack of intermediate shafts, all stress points are on the blades, and the shaftless screw pump has a longer pitch. Small, the diameter of the spiral pipe is small, which will cause excessive pressure, so the blades of the traditional shaftless screw conveyor are seriously damaged and need to be replaced frequently. Due to the large force on the blades, the existing shaftless screw conveyor has a small pipe diameter and a small conveying capacity, which cannot meet the conveying requirements in some occasions. ...
