Description
Technical Field
The utility model belongs to the auger conveyer field, concretely relates to hollow screw axis of sectional type.
Background
The auger conveyor is also called a screw conveyor, a rotating screw shaft pushes materials to carry out screw conveying, and the screw conveyor is widely applied to various industries. The spiral conveyer is suitable for horizontal or inclined conveying of powdery, granular and small blocky materials, the temperature of the materials is less than 200 ℃, and the spiral conveyer is not suitable for conveying easily-deteriorated, viscous and easily-caked materials. The auger conveyor is suitable for horizontal conveying, inclined conveying, vertical conveying and other forms of granular or powdery materials. The conveying distance varies according to the machine type, and is generally from 2 meters to 70 meters. The conveying principle of the auger conveyor is as follows: the material is pushed by the rotary screw shaft to be conveyed spirally. The structure is characterized in that: the rotating shaft of the screw conveyor is welded with a screw shaft. The double screw conveyor is a screw conveyor having two rotating shafts each welded with a rotating shaft. The two screw conveyors are organically combined together to form the screw conveyor. The rotating direction of the rotating shaft of the screw conveyor determines the conveying direction of materials, but the rotating shaft of the screw conveyor is designed according to single conveying in general design. The screw shafts are divided into hollow screw shafts and solid screw shafts, the solid screw shafts are provided with screw blades on the shafts, and the hollow screw shafts are only composed of the screw blades.
In the prior art, a hollow screw shaft used by an auger conveyor is generally a hollow screw shaft integrally formed by injection molding, and the hollow screw shaft is generally thin, so that the hollow screw shaft integrally formed by injection molding has the problems that the strength and the rigidity can not meet the requirements and the hollow screw shaft is easy to break. Meanwhile, when a certain section of the hollow screw shaft is corroded, the hollow screw shaft is difficult to repair, so that the whole hollow screw shaft is scrapped.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome prior art hollow screw axis intensity and rigidity can not reach the requirement, and easy cracked is not enough, provides a sectional type hollow screw axis, include: the spiral shaft body is fixedly connected with the driving connecting shaft through the fixing piece.
Furthermore, one end of the spiral blade is provided with a convex block, and the other end of the spiral blade is provided with a groove.
Further, a reinforcing sheet is arranged at the welding position of the spiral blade.
Furthermore, the driving connecting shaft is provided with a clamping groove and a slot.
Further, the slot is a threaded slot.
Further, the helical blade is a stainless steel helical blade.
The utility model discloses the beneficial effect who possesses:
1. the hollow spiral shaft is designed into a sectional type, a plurality of spiral blades are welded to form the spiral shaft, and the welding part is reinforced, so that the strength and the rigidity of the hollow spiral shaft are enhanced;
2. the hollow screw shaft is designed into a sectional type, when a certain section is corroded, the screw blade of the corroded section can be knocked off, and a new screw blade is replaced for welding, so that the service life of the hollow screw shaft is prolonged.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1-2, the present invention provides a sectional hollow screw shaft, comprising: drive connecting axle 1, stationary blade 2 and a plurality of helical blade 3, a plurality of helical blade 3 welding form the spiral axis body, and the spiral axis body passes through stationary blade 2 and 1 fixed connection of drive connecting axle, and drive connecting axle 1 is used for connecting drive arrangement.
One end of each spiral blade 3 is provided with a convex block, the other end of each spiral blade 3 is provided with a groove, the adjacent spiral blades 3 are connected through the convex blocks and the grooves in a clamping mode and then welded at the clamping connection positions of the adjacent spiral blades, the connection mode is very firm, the integral rigidity and strength of the hollow spiral shaft are guaranteed, meanwhile, when a certain section of the hollow spiral shaft is corroded, the spiral blades at the corroded section can be knocked off, new spiral blades are replaced, the spiral blades are connected through the convex blocks and the grooves in the clamping mode and then welded at the clamping connection positions of the spiral blades, and the service life of the hollow spiral shaft.
In order to further ensure the strength, a reinforcing sheet 4 is welded at the joint of the spiral blade 3 for reinforcement.
The side of the driving connecting shaft 1 is provided with a clamping groove 5, and the end surface is provided with a slot 6. The slot 6 is a threaded slot, the driving connecting shaft 1 is in threaded connection with the driving device through the slot 6, the driving connecting shaft can be effectively driven to rotate, meanwhile, the driving device is convenient to disassemble, the clamping portion and the clamping groove 5 can be arranged on the driving device and connected in a clamping mode, the rotating stress of the driving connecting shaft 1 is dispersed, and energy consumption is reduced.
For corrosion resistance, the helical blade 3 is preferably a stainless steel helical blade.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
