Description

Screw feeder

Technical Field

The utility model relates to a fodder conveyor.

Background

The term "feed" is a general term for food of all human-raised animals, and in a narrow sense, a general feed mainly refers to food of agricultural or animal-raised animals. The Feed (Feed) comprises more than ten kinds of Feed raw materials such as soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, grease, meat and bone meal, grains, Feed additives and the like. The spiral feeder is needed in the feed processing process, and the feed can be stirred, mixed and fed. However, in the feeder in the prior art, once the conveying amount is large in the conveying process, the feeder is easily blocked, and the feeder needs to be cleaned regularly.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a spiral feeder can improve the delivery capacity to avoid the jam of feeder, the delivery capacity is stable.

In order to achieve the purpose, the utility model provides a screw feeder, the novel nipple rectifier comprises a cylindrical shel, be provided with the pivot in the barrel, be provided with helical blade in the pivot, the top of the feeding section of barrel is provided with the feed inlet and links to each other with the feeder hopper, the bottom of the ejection of compact section of barrel is provided with the discharge gate, pitch between the helical blade is crescent along ejection of compact direction, be provided with broken mechanism on the feeding section.

Compared with the prior art, the beneficial effects of the utility model reside in that, the fodder is sent into the feed section that gets into the feeder barrel through the feed inlet from the feeder hopper, the motor rotates, it rotates to drive the pivot, it is rotatory to change epaxial helical blade, and then it transports towards the ejection of compact section constantly to drive the fodder along between the helical blade, because pitch between the helical blade grow gradually, the fodder is difficult to by the compaction caking, and the fodder mobility obtains strengthening, make the fodder can not gather in data send process, avoid the fodder to block up, the fodder falls into back and crushing mechanism contact from the feed inlet simultaneously, can smash caking etc. in the fodder, make the fodder can be carried more easily, be difficult for gathering the jam at the feed section, can improve the conveying capacity, and avoid the jam of feeder, the conveying capacity is stable, the utility model is used for the fodder mixed transportation.

As a further improvement, the diameter of the helical blade is gradually increased along the discharging direction, so that the conveying capacity can be increased, the feed in the feeding section can be rapidly conveyed away, and the feed section is further prevented from being blocked by feed accumulation.

As the utility model discloses a further improvement, broken mechanism is including setting up the dead lever in the pivot, the top of dead lever is provided with broken head, the dead lever sets up between helical blade, and like this when the fodder falls into the back from the feed inlet, the pivot rotates, drives the dead lever and rotates, and then makes broken head rotate, and the broken head of pivoted and the fodder contact that falls into can smash the caking in the fodder, and then be convenient for carry, avoid the caking to pile up and lead to the feeding section to block up.

As the utility model discloses a further improvement, the top of the transport section of barrel is provided with the uide bushing, the bottom processing of uide bushing is the arc that matches with helical blade, and when fodder was carried in the transport section like this, the fodder can be transported the direction and be injectd between helical blade and uide bushing for the fodder is high in the coefficient of filling with of transport section, and the delivery capacity is more stable.

As a further improvement, the part of pivot in ejection of compact section is provided with double helical blade, passes through double helical blade like this for under the unchangeable condition of helical blade's helical pitch, the material of carrying is unchangeable, and pitch reduces simultaneously, and the extrusion force that the fodder was received reduces, and then the fodder is difficult to the caking, makes the fodder fall from the discharge gate more easily.

As a further improvement, the bottom of barrel is the inclined plane of downward sloping, and the fodder can receive the gliding of the effect of gravity like this, and the effect that can cooperate helical blade removes towards ejection of compact section, further avoids the jam of fodder.

As the utility model discloses a further improvement, the top of the ejection of compact section of barrel has been seted up and has been prevented the sprue, prevent supporting being provided with on the sprue and prevent the closure plate, in case the condition that the discharge gate blockked up appears like this, can prevent the closure plate through opening, artifical instrument is deep to prevent that the feed that the sprue blockked up ejection of compact section is dredged, and then can resume the operation fast.
