Abstract

The hopper automatic dumping device comprises an upper hopper storehouse and a lower hopper storehouse, wherein two guide rails which supply the upper hopper storehouse to process are arranged at the outer side of an upper portion of the lower hopper storehouse. A row of rotary drums are horizontally arranged at the lower portions of the guide rails, wherein a bin gate at the bottom of the upper hopper storehouse tightly sticks the rotary drums to process. The hopper automatic dumping device is characterized in that guide rails which can continuedly supply the upper hopper storehouse to process are placed at the top of the lower hopper storehouse, a bin gate which is in rotational connection through a rotating shaft is placed at the lower portion of the upper hopper storehouse in the back side of the direction of laying-off processing. By the adoption of the eccentric-type bin gate, a center of gyration of the bin gate cannot coincide with centers of the bottoms of hopper storehouses. When the upper hopper storehouse slowly process to the end of the rotary drum, a gap between the bin gate and bottom of the hopper storehouses is gradually widen. With gravity driving, the bin gate gradually opens. Materials simultaneously move downward with open of the bin gate until the whole bin gate is opened and laying-off is finished. When the materials are laid-off, the materials cannot be blocked by the bin gate. The hopper automatic dumping device is simple in structure, and perfect in sealing efficiency. The bin gate opening is reliable, powder is not prone to drifting away to protect the environment and save raw materials.

Description

A kind of hopper automatic discharge unit

Technical field

The utility model relates to a kind of hopper automatic discharge unit of a kind of conveying machinery, particularly conveying powdery material.

Background technology

Powder material generally can pass through the steps such as conveying, mixing, weighing in making or packaging process, have a plurality of bunkers and dock laggard row loading, unloading material or carry out the operations such as mixing of powder in these processes.In the prior art, the general discharging opening place center superposition bottom bunker of the door center of gyration of discharge bin, door is the two halves shape along center shaft, the door forebody down moves during discharging, the up motion that door is latter half of, halves is overturn, and its path of motion is on same arc track.The door of this discharge bin is when the upset discharging, and the latter half of door that powder material is easy to overturn hinders, and causes that then powder flies away, serious environment pollution, waste raw MAT'L.In addition, because door need to overturn in discharging opening, so the area of door must be less than discharging opening, therefore have certain gap between door and the discharging opening inwall, easily cause the unrestrained of powder material in discharge bin is being advanced transportation, its sealing effectiveness is relatively poor.

Summary of the invention

Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, provides a kind of simple in structure, door to open hopper automatic discharge unit reliable, that powder is difficult for flying away.

The utility model has adopted following technical proposal to solve its technical matters: a kind of hopper automatic discharge unit, comprise material loading hopper and blanking hopper, the outside of blanking hopper top is fixedly equipped with keeps supplying two guide rails that bunker is advanced, this guide rail lower horizontal is equipped with a row can make material loading hopper bottom door be close to the cylinder that it is advanced, it is characterized in that: the top of blanking hopper is equipped with can continue the guide rail of admitting the material loading hopper to advance, material loading hopper bottom during along discharging the rear side of working direction be equipped with a door that is rotationally connected by rotating shaft.

The utility model adopts the centering type door, and the door center of gyration does not overlap with the center of bunker bottom.Therefore when the material loading hopper slowly marches to the end of cylinder, the gap of door and bunker bottom progressively increases, under the promotion of gravity, door is opened gradually, material moves downward simultaneously with door, until all discharging is opened and finished to door, and in the time of discharging, door can not form material and hinder.The utility model is simple in structure, sealing effectiveness is desirable, and door is opened reliably, powder is difficult for flying away, and has protected environment, has saved raw MAT'L.

The specific embodiment

The utility model will be further described below in conjunction with embodiment and accompanying drawing.

See figures.1.and.2, the utility model comprises material loading hopper 10 and blanking hopper 20.The outside of blanking hopper 20 tops is fixedly equipped with can keep supplying two guide rails 30 that bunker 10 is advanced, and the top of blanking hopper 20 is equipped with can continue two guide rails 40 admitting material loading hopper 10 to advance.The guide rail 40 at the guide rail 30 of these blanking hopper 20 upper outer and blanking hopper top, its inboard are equipped with respectively protruding stupefied 11 guide grooves of advancing therein 31 of the guiding that can hold material loading hopper 10 bottoms and guide groove 41.

The lower horizontal of the guide rail 30 of described blanking hopper 20 upper outer is equipped with a row can make material loading hopper 10 bottom doors 13 be close to its cylinder of advancing 50, and this cylinder 50 is rotationally connected with guide rail 30 respectively by its bearings at both ends 60.

The rear side of described material loading hopper 10 bottoms working direction a during along discharging is equipped with a door 13 that is rotationally connected by rotating shaft 12.

Door 13 areas of material loading hopper 10 bottoms are greater than the area in material loading hopper 10 discharging exits 14.

The utility model when material loading hopper 10 on guide rail 30 during parallel, described door 13 is close on the cylinder 50, closes shape so be, and door 13 greater than material loading hopper 10 discharging exits 14 therefore the leakage phenomenon of powder material can not occur.

With reference to Fig. 3 and Fig. 4, and when material loading hopper 10 arrives blanking hopper 20 head rail 40, because this guide rail does not arrange cylinder for 40 times, therefore thereby powder material relies on gravity to open door 13 enters blanking hopper 20.

Oppositely move after material loading hopper 10 has unloaded material when resetting, its door 13 continues to be closed condition by cylinder 50 pressings, can proceed charging after therefore resetting.
