Abstract

The utility model discloses a shaftless screw conveyer which comprises a shaftless screw vane arranged in a machine casing, the shaftless screw vane is driven by a power device comprising an electric motor and a speed reducer to rotate, and the shaftless screw vane has equal-diameter and variable-screw pitch mode. The shape of a section of the shaftless screw vane has an L-shaped or trapezoid-shaped structure, wherein a turning point of the side of the L-shaped section has an arc transition structure; and the side of the trapezoid-shaped section has the arc transition structure. The amount of feeding amount of the shaftless screw conveyer with variable-screw pitch mode is easy to be controlled, and overstock of materials is not easy to occur on a discharge hole end.

Description

A kind of Shaftless screw conveyor
Technical field
The utility model relates to the Shaftless screw conveyor technical field.
Background technology
Shaftless screw conveyor is widely used in the mass transport in fields such as food, metallurgy, chemical industry, building, mine.Shaftless screw conveyor has screw conveyor shaft to compare with tradition, owing to adopt no central axle designs, the integrated steel helicallobe that utilization has certain flexibility pushes material, thereby has following outstanding advantage: anti-prehensile is strong, and is banded for carrying, easily twine material special preceence is arranged; Good environmental protection, torque is big, energy consumption is low; Because spiral does not have axle, material is difficult for stopping up, thereby can turn round than low velocity, and steadily transmission cuts down the consumption of energy.Shaftless screw conveyor is by the conveying of the spiral rotation promotion material of blade, thereby the effect of blade is extremely important.But present Shaftless screw conveyor uses the constant pitch blade, and what of its feeding coal are wayward, and overstocking of material appears in discharge port end easily.
The utility model content
Technical problem to be solved in the utility model just provides a kind of Shaftless screw conveyor, how many controls easily of its feeding coal, and also discharge port end is not prone to overstocking of material.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Shaftless screw conveyor, comprise the Shaftless spiral blade of being located in the casing, the engine installation driven in rotation that described Shaftless spiral blade is made up of motor and speed reducer is characterized in that: described Shaftless spiral blade is the variable pitch structure.
As preferably, the described Shaftless spiral blade of described Shaftless spiral blade is equal diameter or becomes diameter structure.
As preferably, the cross sectional shape of described Shaftless spiral blade is L shaped cross section or trapezoid cross section.Increased the rigidity of blade, longer service life.When convey materials, conveyor screw can not be lifted, and crushing resistance is strong, and when putty took place, blade was not yielding.
As further improvement, described L shaped cross section bending side is established arc structure, and described trapezoid cross section side is established arc structure.Can prevent the stress concentration of turning point, be suitable for mass transport again.
In addition, the cross-sectional plane of described casing takes the shape of the letter U or V-arrangement, and the casing inside bottom surface is equipped with abrasion-proof backing block.
Shaftless spiral blade of the present utility model has been owing to adopted equal diameter, variable pitch form, and what of Shaftless screw conveyor feeding coal are more easy to control, and discharge port end is not easy to occur overstocking of material.

The specific embodiment
As shown in Figure 1, be the scheme drawing of the utility model Shaftless screw conveyor.Establish Shaftless spiral blade 1 in the casing 2, the engine installation driven in rotation that described Shaftless spiral blade 1 is made up of motor 5 and reductor 6, the cross-sectional plane of described casing 2 takes the shape of the letter U or V-arrangement, casing 2 supports by supporting underframe 3, casing is provided with inlet point 21 and discharging opening 22, casing 2 tops are provided with cover 4, and described casing 2 inside bottom surface are equipped with abrasion-proof backing block.Described Shaftless spiral blade 1 is equal diameter, variable pitch form, and it is divided into two sections or multistage according to the pitch size, and the pitch of its posterior segment is greater than the pitch of leading portion.Material is from leading portion section conveying backward like this, and the relative leading portion of the mass transport speed of back segment can be fast, and the material that can eliminate back segment overstocks.As Fig. 3 and shown in Figure 5, the cross sectional shape of described Shaftless spiral blade is L shaped cross section, wherein the bending side in L shaped cross section is the arc transition structure at bending part only among Fig. 3, the whole bending side in L shaped cross section all is circular-arc among Fig. 5, as Fig. 7 and shown in Figure 9, the cross sectional shape of described Shaftless spiral blade is the trapezoid cross section, and wherein the whole side in trapezoid cross section all is circular-arc among Fig. 7, among Fig. 9 the bottom surface, trapezoid cross section also extend downwards one section square.
Material enters casing through inlet point, the driven by motor reductor, and reductor drives Shaftless spiral blade.The Shaftless spiral blade rotation, material moves, and along with the variation of pitch, material is accelerated in back one section speed of transmission, finally falls at discharging opening.
