Abstract
The utility model discloses a kind of gradient pitch conveyor screw, comprise screw rod, helicallobe and cell body, one end of described screw rod is actuating device, and the other end is bearing seat; The two ends of described cell body have inlet point and discharging opening; The pitch of described helicallobe increases gradually to discharging direction.The utility model helicallobe increases gradually to the pitch in discharging section direction, and delivery speed is accelerated gradually, effectively can realize the conveying effect that charging is slow, discharging is fast, and the situation that effectively prevent feed blocking occurs.
Description
Technical field
The utility model relates to helical feed technical field, particularly relates to a kind of gradient pitch conveyor screw.
Background technology
Conveyor screw, is commonly called as auger, is a kind of continuous conveying equipment, mainly for delivery of powdery, graininess and little lump material.Conveyor screw has that structure is simple, cross-sectional area is little, good seal performance, can in the middle of multiple feed and discharging, the advantage such as easy-to-operate and low cost of manufacture, is therefore widely used.
Conventional helical conveyer is when convey materials, and helicallobe and adjoining spiral blade are identical in the distance of the axis of screw rod, i.e. constant pitch conveyor screw.Operationally, helicallobe can rub with the cell body inwall surrounding helicallobe, and material has one and cannot be fed forward under the promotion of helicallobe, namely can cause certain transport loss, so just easily causes blocking.When there is blocking, usual way stops feeding in raw material, and after feed blocking situation is alleviated, then continues reinforced, transmission efficiency will be made like this to decrease.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of gradient pitch conveyor screw not easily occurring to block.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of gradient pitch conveyor screw, is characterized in that: described conveyor screw comprises screw rod, helicallobe and cell body, and one end of described screw rod is actuating device, and the other end is bearing seat; The two ends of described cell body have inlet point and discharging opening; The pitch of described helicallobe increases gradually to discharging direction.
Preferably, the ratio of pitch that described helicallobe is adjacent between helicallobe that pitch between the helicallobe of charging side and described helicallobe be adjacent discharging side is 0.95 ~ 0.99.
Further, in order to prevent helicallobe and cell body collision deformation, improve the crocking resistance of helicallobe, the marginal end portion of described helicallobe is welded with wear-resisting edge strip simultaneously.
Principle of work of the present utility model and beneficial effect are: helicallobe can rub with the cell body inwall surrounding helicallobe, material is understood some and is detained, and cannot be fed forward under the promotion of helicallobe, the material of conveyor screw to overload is very sensitive, easy generation latch up phenomenon, in order to reach good feed status, the employing gradient pitch of helicallobe of the present utility model.Easily there is buildup blocking in one end of inlet point, the pitch of feed end helicallobe is relatively little, and when screw speed inconvenience, the delivery speed of feed end is the slowest; Helicallobe increases gradually to the pitch in discharging section direction, and delivery speed is accelerated gradually, effectively can realize the conveying effect that charging is slow, discharging is fast, and the situation that effectively prevent feed blocking occurs.
Accompanying drawing explanation
Figure 1 shows that the structural representation of gradient pitch conveyor screw.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
Figure 1 shows that a kind of gradient pitch conveyor screw, comprise screw rod 1, helicallobe 2 and cell body 3, one end of described screw rod 1 is actuating device 4, and the other end is bearing seat 5; The two ends of described cell body 3 have inlet point 6 and discharging opening 7; The pitch of described helicallobe 2 increases gradually to discharging direction.Helicallobe can rub with the cell body inwall surrounding helicallobe, material is understood some and is detained, and cannot be fed forward under the promotion of helicallobe, the material of conveyor screw to overload easily produces latch up phenomenon, in order to reach good feed status, the employing gradient pitch of helicallobe of the present utility model.Easily there is buildup blocking in one end of inlet point, the pitch of feed end helicallobe is relatively little, and when screw speed inconvenience, the delivery speed of feed end is the slowest; Helicallobe 2 increases gradually to the pitch in discharging section direction, and delivery speed is accelerated gradually, effectively can realize the conveying effect that charging is slow, discharging is fast, and the situation that effectively prevent feed blocking occurs.
Preferably, the ratio of pitch L2 that described helicallobe is adjacent between helicallobe that pitch L1 between the helicallobe of charging side and described helicallobe 2 be adjacent discharging side is 0.95 ~ 0.99.If conveyor screw belongs to tilt feeding, partial material can retroject under gravity, this be will be suitable increasing helicallobe 2 between pitch difference, to realize better carrying effect.
Further, in order to prevent helicallobe 2 and cell body 3 collision deformation, improve the crocking resistance of helicallobe 2, the marginal end portion of described helicallobe 2 is welded with the wear-resisting edge strip of 45 steel matter simultaneously.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
1. a gradient pitch conveyor screw, is characterized in that: described conveyor screw comprises screw rod, helicallobe and cell body, and one end of described screw rod is actuating device, and the other end is bearing seat; The two ends of described cell body have inlet point and discharging opening; The pitch of described helicallobe increases gradually to discharging direction.
2. a kind of gradient pitch conveyor screw according to claim 1, is characterized in that the ratio of the pitch that described helicallobe is adjacent between helicallobe that pitch between the helicallobe of charging side and described helicallobe be adjacent discharging side is 0.95 ~ 0.99.
