Specific embodiment

With reference to the accompanying drawings and examples, the utility model is described in detail.

Aeration tube processing feeding device, referring to Fig.1, including hopper 1, the top of hopper 1 are in cube structure, and lower part is in The pyramid shape set.Shape material chamber 11 identical with its shape is offered in hopper 1；Connection is offered on the top of hopper 1 Expect chamber 11 and extraneous feed inlet 12, fixation is communicated with discharge pipe 2 in the bottom of hopper 1, and discharge pipe 2 is connected to vacuum Pump provides the power of conveying material by vacuum pump.When feeding, staff puts into raw material in material chamber 11 from feed inlet 12, It is delivered in specified agitating device and is processed from power mechanisms such as vacuum pumps with discharge pipe 2 again.

Referring to Fig.1, steel bar is provided in material chamber 11 and weaves the string bag 3 that is welded, the opening of the string bag 3 towards into Material mouth 12, and its opening edge is fixed along the inside edge of feed inlet 12 is fixedly welded on to realize and install.

It is closed in the lid of feed inlet 12 and is connected with capping 4, capping 4 is placed in outside hopper 1, and the side of one side is equipped with hinge, and The outer edge for being articulated with feed inlet 12 is realized by hinge, is closed so as to realize to cover feed inlet 12.The capping 4 that lid closes deviates from Expect 11 side of chamber, is welded with handle 41 in free side.

When feeding, staff first will storage have raw material sack slip off an openning, then lifted, with openning to Under posture put into feed inlet 12, fall in it in string bag, hold later capping 4 active side it is rotated, utilize capping 4 cover Close feed inlet 12.

Since feed inlet 12 is closed when raw material is detached from sack and the string bag under the effect of gravity, it is possible to limit raw material fugitive dust It makes in material chamber 11, and guarantees normal feeding, so that the utility model can optimize workshop condition, protect the body of staff Health.

Referring to Fig.1, the inclination of feed inlet 12 is arranged upward, and towards equipment front side, to facilitate staff's feeding.It is feeding Mouth 12 is welded with supporting plate 13 on the outside of lower edge, supporting plate 13 is laterally extended close to the outer edge of bottom surface side.

When staff's feeding, raw material bag can be taken and be placed on supporting plate 13, power is borrowed to facilitate as support and temporarily stopped Breath, while the position of raw material bag is adjusted, after guaranteeing that it falls in the string bag 3, raw material can be normally detached from, to guarantee using effect.

Referring to Fig.1, due to by capping 4 closure of feed mouths 12 can only temporary prevention fugitive dust be dispersed into workshop, and Still there is part fugitive dust to run out of when opening capping 4, so the utility model further includes air draft mechanism 5.

Air draft mechanism 5 includes gas pipeline 51 and blower 52.Wherein gas pipeline 51 wears the top for being fixed on hopper 1 vertically Portion, and it is connected to material chamber 11 and the external world.Blower 52 is fixed on the external one end of gas pipeline 51, and inlet end is in communication.In wind The exhaust end of machine 52 is connected to and is fixed with exhaust pipe 53, and exhaust pipe 53 is connected to an air filter 6.

In feeding operation, staff opens blower 52, and blower 52 is extracted from material chamber 11 empty by gas pipeline 51 Gas, and fugitive dust is siphoned away together, then the air containing fugitive dust is exported to air filter 6, by sky by exhaust pipe 53 Air filter 6 is discharged after filtering, to reduce the fugitive dust in material chamber 11, reinforces using effect.

Referring to Figures 1 and 2, it to further strengthen using effect, is equipped in material chamber 11 for opening bag to raw material bag automatically Bag openning body 7.

Port 31 is laterally opened up on the bottom surface of the string bag 3, port 31 runs through 3 bottom surface of the string bag.Bag openning body 7 includes cutter 71 And telescoping cylinder 72, cutter 71 is plate-like, and the knife edge protrudes into the string bag 3, and telescoping cylinder is fixed in its part for being placed in the net of the string bag 3 72 tailpiece of the piston rod.The telescopic direction of telescoping cylinder 72 is parallel to the lateral length of port 31, and cylinder body is fixedly connected on material chamber 11 Inner wall.Cylinder or oil cylinder may be selected in telescoping cylinder 72.

When staff launches raw material bag on the string bag 3, and it is past that telescoping cylinder 72 will be can control after 4 closure of capping Multiple flexible, with band 71 reciprocating cutting raw material bag side directed downwardly of cutter, bag is opened in realization, is detached from the string bag 3 for raw material and is carried out feeding.

7 one side of bag openning body makes staff that need not manually open bag again, and use is more convenient, on the other hand makes original Expect that fugitive dust probability is smaller, to advanced optimize workshop condition.

Referring to Fig. 2 and Fig. 3, a bag effect is opened for guarantee cutter 71, needs periodically more to protect it maintenance, therefore in telescoping cylinder 72 tailpiece of the piston rod is fixedly connected with a connecting column 81, and a connecting sleeve 82 is fixedly connected on cutter 71 as knife handle；Connector sleeve Pipe 82, which is arranged, is fixed on connecting column 81, thus the carry out installing and dismounting that cutter 71 can be convenient, to repair replacement.Connector sleeve Bolt is radially worn on pipe 82, bolt synchronous wears connecting column 81, with reinforce both bonding strength, guarantee using effect not by Interference.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
