Abstract
The utility model provides a groove type spiral material conveying system which mainly solves the problems that an existing spiral material conveying system is large in input torque, energy is wasted, characters of materials are changed, and quality of the materials is bad. The groove type spiral material conveying system comprises at least two groove type spiral material conveying devices which are arranged on the bottom portion of a storage bin. Each groove type spiral material conveying device is composed of a screw and a spiral blade which is arranged on the screw. Each spiral blade is separated into N sections, wherein N is a natural number which is larger than or equal to 2. The spiral distance between the spiral blades in each section is equal. The spiral distance between sections of the spiral blades increases gradually from the materials to a material outlet. Non-blind-angle storage can be achieved through a special storage bin structure and the groove type spiral material conveying devices of the groove type spiral material conveying system, and the space of a box body can be utilized to maximum, and thus the groove type spiral material conveying system has the advantages of being simple in structure and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of groove type helical conveying system, and this device is used for the material integral body of bin bottom is sent, and belongs to the road building equipment technical field.
Background technology
Screw input feeder is the device that utilizes the rotation of spiral that the material in concentric semicircle hopper is carried.Material in the hopper is because gravity reaches the effect to the cell wall friction force, and on the go does not rotate with spiral, but moves along hopper with the slip form, and auger loader is multiplex in horizontal feed, and when being used for tilting to carry, its inclination angle generally should be less than 30 °.Suitable graininess or the granular material of carrying drying, but under the effect of spiral, can cause material crushing.
But the existing screw input feeder that is applied in the road building equipment, because its pitch all equates, material all moves to discharging opening from the screw input feeder root, and be filled all the time from the material that root is input into spiral, in the process of carrying to discharging opening, the material of feed bin can't enter spiral, and the material of feed bin can produce the pressure that continues to spiral, cause the input torque of constant pitch screw input feeder very large, wasted the energy; Material also might cause the characteristic of material to change to the pressure of spiral, and the quality of material is degenerated.
Summary of the invention
The utility model provides a kind of groove type helical conveying system, and it is very large mainly to have solved existing spiral conveying system input torque, wastes energy, and the characteristic of material is changed, the problem that the quality of material is degenerated.
Concrete technical solution of the present utility model is as follows:
This groove type helical conveying system comprises at least two groove type helical feeders that are fixedly installed on bin bottom, the groove type helical feeder is made of screw rod and the helicallobe that is arranged on the screw rod, described each helicallobe is divided into the N section, N is the natural number more than or equal to 2, pitch between the helicallobe in described each section equates that the pitch between each section helicallobe increases progressively to the material outlet moving direction along material.
The angle of above-mentioned groove type helical feeder hypotenuse and horizontal surface is α, and the α angle is greater than the angle of repose of material.
Above-mentioned groove type helical feeder connects by flange or the mode of welding is fixedly installed on bin bottom.
Above-mentioned groove type helical feeder is three and is arranged on same plane that the vertical distance between each groove type helical feeder is identical.
The pitch of maximum is less than the external diameter of helicallobe between above-mentioned each section helicallobe.
Minimum pitch is greater than half of helicallobe external diameter between above-mentioned each section helicallobe.
Pitch increasing progressively as equal difference along material to the material outlet moving direction increases progressively between above-mentioned each section helicallobe.
The length of above-mentioned each section helicallobe can be set to identical or different, considers according to reality processing, take identical and length 1000mm as good.
The utility model has the advantage of:
This groove type helical conveying system is with special storage silo structure and groove type helical feeder, can realize without dead angle storage, and the space of the casing rate that can maximize the use.What groove type helical used can be variable pitch groove type helical feeder, or traditional permanent pitch groove type helical feeder, and occasion little in operational throughput or that helix length direction span is short adopts permanent pitch screw input feeder, and it is simple in structure, and manufacturing cost is few; And in the occasion of large operational throughput, large span, the variable-pitch auger feeder just can show its powerful advantage, and the horsepower input of this conveying system is declined to a great extent.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure left view;
Fig. 3 is the utility model groove type helical feeder structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, as shown in the figure:
The groove type helical conveying system is used the groove type helical feeder, and special storage silo respective outer side edges slot type revolves some characteristics of feeder, can realize low-power consumption, the large efficient storage silo of Emptying Rate; Groove type helical conveying system operated by rotary motion is used for the material conveyer of the whole discharging of material in the feed bin at bin bottom.
As shown in Figure 2, long L and the wide B according to storage silo determines screw input feeder length and the screw input feeder quantity of arranging on Width.Wherein the α angle is the angle of hypotenuse and horizontal surface, if in the situation of space permission, the α angle can also equal 90 °, and the α angle is not less than the angle of repose of material, avoids in problems such as the stagnant material of spiral wall.Wide value B1, B2 etc. are set to the amount that equates as much as possible, and it is revised by the α angle and gets, in the parameter that decides screw input feeder according to conveying amount per hour, such as external diameter, pitch, design speed and design horsepower input etc.Can be equipped with above the spiral at each and to cover boom device, can prevent that the material front is pressed on the spiral, reduce the conveying resistance of spiral.
Wherein, the pitch segmentation of variable pitch from the root of spiral to the outlet position of screw input feeder shows a rising trend, the preferred successively mode of equal difference increases, and is the pitch of the actual conveying amount of screw input feeder in the pitch of discharging opening, and the pitch maximum is no more than the external diameter of spiral; The pitch of root generally is not less than 0.5 times spiral external diameter.
In whole conveying process, the position conveying amount less that pitch is little, in the process that pitch increases successively, the conveying amount of spiral is also increasing simultaneously successively, until during the material delivery port of spiral, the conveying amount of spiral equals the design conveying amount of whole spiral.The variable-pitch auger feeder can make the upper integral plane of feed bin material descend, and saves the horsepower input of whole screw input feeder.
On the helix length direction, spiral can be divided into l
1, l
2, l
3, l
4Etc. the pitch that some length distance equate or do not wait, total length is L.The problem that is limited to manufacturing process, it is a lot of that li can not divide, and generally speaking, it is comparatively reasonable that li is made as equal 1000mm.
