Description
Technical field
The utility model relates to Transport Machinery technical field, particularly a kind of conveyor screw screw shaft.
Background technology
Conveyor screw is a kind of conventional equipment of field of transport machinery, in order to the carrying of material, it is a kind of load transfer device of widespread use in the departments such as chemical industry, building materials, grain, mainly for delivery of powdery, graininess and little lump material, there is the advantages such as structure is simple, cross-sectional dimension is little, good airproof performance.Conveyor screw has the shortcomings such as component wear is serious, operational throughput is lower, consumed power is large equally.Material enters into screw shaft from the inlet point of conveyor screw, drives screw shaft to rotate, material is delivered to discharge port from inlet point by gear motor.In the use procedure of reality, because material is easily stacked into above discharge port, cause the screw shaft above discharge port and blade wear exception thereof.Therefore, inventing a kind of New screw conveyer screw shaft that is simply light, that effectively can reduce screw shaft and blade wear thereof above discharge port is a problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide and a kind ofly can reduces the conveyor screw screw shaft of the wearing and tearing of screw shaft and the blocking of material by actv..
For solving the problems of the technologies described above, the utility model provides a kind of conveyor screw screw shaft, comprising:
Steel pipe, transmission shaft and tailing axle;
Described steel pipe is arranged in the chute of conveyor screw, and described steel pipe one end is fixedly connected with described transmission shaft, and the other end is fixedly connected with described tailing axle, and described steel pipe is flexibly connected with described chute by described transmission shaft and described tailing axle;
Described steel pipe is provided with main vane sheet and derotation blade, and be provided with gap section between described main vane sheet and derotation blade, the position of described gap section is relative with the position of the discharge port of conveyor screw;
Described transmission shaft is connected with the gear motor of conveyor screw by coupler, described transmission shaft and tailing axle are used for driving described steel pipe to rotate by described gear motor, thus material is delivered in described discharge port under the effect of described main vane sheet and derotation blade.
Further, the width at described interval is greater than described main vane sheet pitch, but is less than the width of described discharge port.
Further, the material of described main vane sheet and described derotation blade, pitch, thickness, welding manner are consistent, and hand of rotation is contrary.
Further, the material of described main vane sheet and described derotation blade is 16Mn.
Further, described transmission shaft and adopt interference to be connected between tailing axle with described steel pipe.
Further, described steel pipe is thick walled steel tube, and standard is GB/T 17395-1998.
A kind of conveyor screw screw shaft that the utility model provides, by designing main vane sheet and derotation blade cooperatively interacts, simple and light, effectively can reduce the accumulation of material above discharge port, effectively reduce the wearing and tearing of screw shaft and the blocking of material.
Accompanying drawing explanation
The structural representation of a kind of conveyor screw screw shaft that Fig. 1 provides for the utility model embodiment;
The structural representation that Fig. 2 installs for the screw shaft of conveyor screw shown in Fig. 1.
Detailed description of the invention
See Fig. 1, Fig. 2, the utility model provides a kind of conveyor screw screw shaft, comprising: transmission shaft 1, steel pipe 2 and tailing axle 4; Steel pipe 2 is arranged in the chute 6 of conveyor screw, and steel pipe 2 one end is fixedly connected with transmission shaft 1, and the other end is fixedly connected with tailing axle 4, and steel pipe 2 is flexibly connected with chute 6 with tailing axle 4 by transmission shaft 1.Steel pipe 2 is provided with main vane sheet 3 and derotation blade 5, is provided with gap section between main vane sheet 3 and derotation blade 5, and the position of gap section is relative with the position of the discharge port 7 of conveyor screw.The width of gap section is greater than a pitch of main vane sheet 3, but is less than the width of discharge port 7.Transmission shaft 1 is connected with the gear motor of conveyor screw by coupler, and transmission shaft 1 and tailing axle 4 for driving steel pipe 2 to rotate by gear motor, thus make material be delivered in discharge port under the effect of main vane sheet 3 and derotation blade 5.
The material of main vane sheet 3 and derotation blade 5, pitch, thickness, welding manner are consistent, and hand of rotation is contrary.The material of main vane sheet 3 and derotation blade 5 is 16Mn.Transmission shaft 1 and adopt interference to be connected between tailing axle 4 with steel pipe 2.Steel pipe 2 is thick walled steel tube, and standard is GB/T 17395-1998.The material of transmission shaft 1 and tailing axle 4 is 45# steel.
When the conveyor screw screw shaft work using this utility model to provide, be connected on solid drawn pipe by transmission shaft 1, tailing axle 4 by interference fit, the magnitude of interference ensures the moment of torsion needed for screw shaft rotation; Be connected by welding on solid drawn pipe by main vane sheet 3, derotation blade 5, front segment weldering, back side full weld, ensure shape and the Joint strenght of main vane sheet 3, derotation blade 5.Screw shaft is installed to chute 7, the interval between main vane sheet 3 and derotation blade 5 is in directly over discharge port 7, and the length at interval is the half of discharge port width.When material is by main vane sheet 3, main vane sheet 3 clickwise drives above mass transport to discharge port 7, most material is made directly to enter into discharge port 7, part does not directly enter the solid accumulation of discharge port 7 at gap section and derotation blade 5 place, derotation blade 5 left-hand revolution, now, under the effect of derotation blade 5, these leftover materials are delivered in discharge port 7.
A kind of conveyor screw screw shaft that the utility model provides, by designing main vane sheet and derotation blade cooperatively interacts, simple and light, effectively can reduce the accumulation of material above discharge port, effectively reduce the wearing and tearing of screw shaft and the blocking of material.
It should be noted last that, above detailed description of the invention is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to example, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
