Abstract
The utility model relates to a screw feeder, which comprises a screw conveyer and a hopper arranged on a feeding port of the screw conveyer. A material feeding port is arranged on the hopper, a cylinder vertically downward is arranged at the top end of the hopper, and a piston rod of the cylinder downwards extends into the hopper. A flexible pipe connected into the screw feeder from outside the hopper is arranged at the end portion of the piston rod, and an air nozzle is arranged at the end portion of the flexible pipe. During operation, the piston rod of the cylinder extends downwards, and the air nozzle of the flexible pipe enters the lower portion of the hopper to clean materials stacked at the lower portion of the hopper through vapor blasting, thereby avoiding influence on conveying of the materials caused by an overhead phenomenon at all times. Further, manual forced feeding is not required, labor intensity of workers is reduced, and health of the workers is guaranteed. When cleaning is finished, the piston rod of the cylinder moves upwards to restore, therefore the piston rod is prevented from plugging at the bottleneck position of the lower portion of the hopper, and conveying efficiency of the materials is guaranteed.
Description
Technical field
The utility model relates to a kind of screw feeder, particularly a kind of screw feeder that is not prone to arch formation and does not influence feeding speed.
Background technology
Traditional screw feeder comprises auger loader, is located at the pyramid hopper on the auger loader inlet point, establishes the material inlet point on the hopper, after material enters auger loader by the material inlet point, is discharged from discharging opening by the blade promotion of auger loader.Granular material is prone to arch formation after entering feeder, causes material occurring in the hopper middle and lower part and makes somebody a mere figurehead, and can't enter auger loader and transport out, and influences the serialization ordinary production.At present general solution is the inspection by the workman, just utilizes instrument to knock hopper in case take place to build bridge, and makes it produce vibration, the elimination arch formation takes place, or the direct labor directly stirs the material of making somebody a mere figurehead, and labor strength is big, dust is more, and this occupational health health to the employee has caused injury.
Occur a kind of screw feeder that solves arch formation at present, a gas ejector pipe that stretches into the hopper bottom has been set on the hopper top, when occurring building bridge, gas ejector pipe by pressurized air, has been realized piling up the cleaning of material.Its shortcoming is: the gas ejector pipe beginning is arranged on the center of hopper, influences the normal conveying of material, has reduced transport efficiency.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of screw feeder that is not prone to arch formation and does not influence feeding speed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of screw feeder, comprise auger loader, be located at the hopper on the auger loader inlet point, establish the material inlet point on the hopper, its innovative point is: the top of described hopper is provided with vertically downward a cylinder, and the piston rod of described cylinder stretches in the hopper downwards; The end of described piston rod is provided with one by the outer flexible pipe that inserts of hopper, and the lower end of flexible pipe is provided with air nozzle, and the upper end of flexible pipe connects compressed air tank.
Advantage of the present utility model is: during work, the piston rod of cylinder stretches out downwards, the air nozzle of flexible pipe enters the bottom of hopper, the material that is deposited in the hopper bottom is carried out liquid honing, avoid occurring the conveying that arch formation influences material always, need not manually to force powder feeding, reduced working strength of workers, guaranteed workers'health.And the cleaning finish after, retract receipts on the cylinder piston rod, avoid getting lodged in the bottleneck of hopper bottom, guaranteed the transport efficiency of material.
Description of drawings
Fig. 1 is the utility model screw feeder structural representation.
The specific embodiment
As shown in drawings, comprise auger loader 1, hopper 2, material inlet point 3, cylinder 4, flexible pipe 5, air nozzle 6.
The inlet point of above-mentioned auger loader 1 is provided with hopper 2, material inlet point 3 is established on hopper 2 tops, and cylinder 4 is arranged on the top of hopper 2, and the piston rod of cylinder 4 has stretched in the hopper 2 vertically downward, the end of piston rod is provided with one by the hopper 2 outer flexible pipes 5 that insert, and the end of flexible pipe 5 is provided with air nozzle 6.
During work, the piston rod of cylinder 4 stretches out downwards, and liquid honing is carried out to the material that is deposited in hopper 2 bottoms in jet 6 mouthfuls of bottoms that enter hopper 2 of flexible pipe 5.And the cleaning finish after, retract receipts on the cylinder piston rod, avoid getting lodged in the bottleneck of hopper 2 bottoms.
