Abstract

The utility model provides a grain screening machine fine screen hopper, relates to the cereals processing machines field, including the hopper body, the hopper body includes pan feeding mouth, pan feeding passageway, buffering cabin, discharging channel and discharge gate, buffering cabin upper end and pan feeding passageway intercommunication, lower extreme and discharging channel intercommunication, this hopper changes the hopper structure of traditional grain screening machine, adopt the extension of pan feeding passageway, and increase buffering cabin's sealing type structure, solve prior art's hopper, going into to fight, grain can produce a large amount of dusts when, pour into and carefully can not produce grain and leak and to spill, grain is piled up too much simultaneously, when leading to follow -up screening grain, the lower problem of screening efficiency, this fine screen hopper is before grain gets into the screening net, carry out the primary screen branch in advance to the grain in the hopper buffering cabin, detach the bold granule, reach the effect of fine screen.

Description

A kind of grain screening machine fine screen hopper

Technical field：

The utility model is related to Cereals Processing Machines field, and in particular to a kind of grain screening machine fine screen hopper.

Background technology：

Grain screening machine is the relative motion using grain with compass screen surface, makes partial particulate pass through sieve aperture, by sand, soil block, gravel The materials such as stone, rubble are divided into the vibration screening machinery equipment of different stage by granular size, can be effective by grain screening machine The impurity in grain is cleaned out, the hopper of the grain screening machine of prior art is mostly open hopper, is carrying out grain Food screening when, typically directly will pour into inside hopper into the grain of bag, this mode is more rough, grain when hopper is poured into, If debris in sack are excessive, grain to enter produce when struggling against substantial amounts of dust, pours into and carefully can not produce grain leakage and spread, while Grain piles up too many, when causing subsequently to sieve grain, the relatively low problem of screening efficiency.

Utility model content：

Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of grain screening machine Fine screen hopper, the hopper changes the hopper construction of traditional grain screening machine, is extended using pan feeding passage, and increases the close of buffering chamber Envelope formula structure, solves the hopper of prior art, and when grain enters and struggles against substantial amounts of dust can be produced, and pours into and carefully can not produce grain Leakage is spread, while grain piles up too many, when causing subsequently to sieve grain, the relatively low problem of screening efficiency, the fine screen hopper is in grain Into before Screening Network, the grain in hopper buffering chamber is once sieved in advance, removed bulk particle, reached the effect of fine screen Really.

Technical problem to be solved in the utility model is realized using following technical scheme：

A kind of grain screening machine fine screen hopper, including hopper body, it is characterised in that：

The hopper body includes feeding mouth, pan feeding passage, buffering chamber, tapping channel and discharging opening, on the buffering chamber End and pan feeding channel connection, lower end connects with tapping channel, and the pan feeding passage end arranges feeding mouth, the tapping channel one End arranges discharging opening, and grain enters pan feeding passage by feeding mouth, is cached by buffering chamber, it is to avoid grain is poured into excessively, is caused Pile up, follow-up screening effect is affected, by tapping channel and discharge hole for discharge.

The feeding mouth arranges O-ring seal, and when the grain in sack pours feeding mouth into, sack is contacted with O-ring seal, grain Food enters feeding mouth through O-ring seal, it is to avoid grain leakage is spread and dust splashes.

The pan feeding vias inner walls are crisscross arranged multiple broken rods, will be broken up into the grain of pan feeding passage by broken rod And bulk particle is smashed, it is to avoid grain is piled up to enter together inside material bin, causes feeding mouth and hopper blocking, both increased Follow-up screening efficiency, can in advance crush the bulk particle of blending in grain again, be easy to follow-up screening, play the effect of fine screen Really.

The buffering chamber top arranges thick mouth screen cloth, and bottom arranges thin mouth screen cloth, will be big in grain by thick mouth screen cloth Block particle and impurity are separated, and the fritter particle and impurity in grain and grain are carried out into secondary separation by thin mouth screen cloth, are increased The precision of follow-up screening.

The beneficial effects of the utility model are：A kind of grain screening machine fine screen hopper is provided, the hopper changes traditional grain The hopper construction of screening machine, is extended using pan feeding passage, and increases the sealed construction of buffering chamber, solves the hopper of prior art The problem of dust is easily produced, the fine screen hopper entered in advance before grain enters Screening Network to the grain in hopper buffering chamber Row is once sieved, and removes bulk particle, reaches the effect of fine screen.

Fig. 2 is the top view of thick mouth screen cloth of the present utility model.

Fig. 3 is the top view of thin mouth screen cloth of the present utility model.

Specific embodiment：

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

As shown in Figure 1, 2, 3, a kind of grain screening machine fine screen hopper, including hopper body 1, it is characterised in that：

The hopper body 1 includes feeding mouth 11, pan feeding passage 12, buffering chamber 13, tapping channel 14 and discharging opening 15, institute State the upper end of buffering chamber 13 to connect with pan feeding passage 12, lower end connects with tapping channel 14, described one end of pan feeding passage 12 sets into Material mouth 11, one end of the tapping channel 14 arranges discharging opening 15.

The feeding mouth 11 arranges O-ring seal 111.

The inwall of pan feeding passage 12 is crisscross arranged multiple broken rods 121.

The top of the buffering chamber 13 arranges thick mouth screen cloth 131, and bottom arranges thin mouth screen cloth 132.

General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of without departing from the utility model spirit and scope, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model Claimed scope is by appending claims and its equivalent thereof.
