Abstract
The invention discloses an efficient negative pressure cereal loading machine. The efficient negative pressure cereal loading machine comprises a hopper. The feed port of the hopper is connected with a loading pipe, and the other end of the loading pipe is connected to the feed port in the upper end of a transition bin. A vertical storage pipe is arranged at the discharge port in the bottom of the transition bin, an air suction pipe is arranged at the air outlet in one side of the transition bin, and the other end of the air suction pipe is connected with a fan. An exhaust pipe is vertically connected to the air outlet of the fan, a separator is connected to the bottom of the exhaust pipe, a recovery pipe is connected with the separator, and the other end of the recovery pipe is connected in the hopper. According to the efficient negative pressure cereal loading machine, the transition bin is higher than the hopper, after the fan is started, cereals flow into the transition bin from the hopper through the loading pipe due to the negative pressure of the transition bin, and due to the fact that the unit weight and the kinetic energy of impurities are smaller than those of the cereals, the impurities can be separated from the cereals by reasonably controlling the rotation speed of the fan. According to the efficient negative pressure cereal loading machine, damage to the surfaces of the cereals is small, the noise is small, the impurities can be separated through the separator, and the cleaning time for the cereals is saved.
Description
Technical field
The present invention relates to a kind of high-efficiency negative-pressure cereal feeder, belong to packing, packaging and the technical field of processing equipment of cereal.
Background technology
Along with the increase that country drops into agricultural, grain yield is increasing year by year, and crops processing also just progressively realizes automation, and the use amount of its feeder also increases year by year.At present, bucket type material loading in cereal material-uploading style, belt filled, spiral material loading, defect has: volume is large, floor area is large, heavy, noise large, destructible cereal surface, and cannot remove leaf, chaff shell and the flat grain in cereal, and vacuum feeding, in feeding process, be usually step material loading, efficiency is low.
Summary of the invention
The object of the invention is: a kind of high-efficiency negative-pressure cereal feeder is provided, in material loading, can remove in time the problem of leaf, chaff shell and flat grain in cereal, and it is low to overcome traditional material loading plant efficiency, the problems such as noise is large, destructible cereal surface, to overcome the deficiencies in the prior art.
Technical scheme of the present invention
A kind of high-efficiency negative-pressure cereal feeder, comprise hopper, inlet point place at hopper is connected with feeding tube, the feeding tube other end is connected to the inlet point place of transitional storehouse upper end, vertically storing pipe is arranged on the discharging opening place of transitional storehouse bottom, aspirate tube is arranged on the air extractor duct place of transitional storehouse one side, aspirate tube other end connecting fan, freeing pipe is vertically connected to air extractor duct one place of blower fan, disconnector connects freeing pipe bottom, Through Flow Line (TFL) connects disconnector and its other end is connected in hopper, in this equipment, transitional storehouse is higher than hopper, starting after blower fan, cereal is because thereby transitional storehouse negative pressure flows in transitional storehouse from hopper by feeding tube, because foreign material unit weight and kinetic energy are less than unit weight and the kinetic energy of cereal, rationally control rotation speed of fan, realizing foreign material separates with cereal.
In aforesaid high-efficiency negative-pressure cereal feeder, between hopper and feeding tube, be provided with charging by-pass cock.
In aforesaid high-efficiency negative-pressure cereal feeder, described transitional storehouse is three-legged structure, between inlet point and discharging opening, be provided with a baffle plate and form a passage, form a through hole at discharging opening place baffle plate and transitional storehouse, this through hole can be communicated with the air extractor duct of transitional storehouse, and this structure is more conducive to cereal and flows in storing pipe.
In aforesaid high-efficiency negative-pressure cereal feeder, on aspirate tube, be provided with adjusting air flow switch.
In aforesaid high-efficiency negative-pressure cereal feeder, be provided with discharge door in discharge nozzle exit position, discharge door is connected with counterweight by lever.
In aforesaid high-efficiency negative-pressure cereal feeder, described disconnector is respectively equipped with air outlet one and air outlet two, air outlet one is positioned under disconnector and connects freeing pipe, air outlet two is positioned at disconnector side, wherein the cross section of air outlet one is less than air outlet two cross sections, under disconnector, the cross section of air outlet one is less than the cross section of side air outlet two, the resistance that air-flow flows downward can be greater than the resistance to side flow, thereby the leaf in cereal, chaff shell, flat grain is discharged from the air outlet two of disconnector side with most gas, and a small amount of cereal is because effect of inertia can be with the gas of fraction in Through Flow Line (TFL) enters hopper, again in feeding tube enters transitional storehouse.
Owing to having adopted technique scheme, compared with prior art, the present invention utilizes grain stream volume property, adopt negative pressure to realize the upwards transport of cereal, do not need to rely on mechanical drive, less to cereal surface breakdown, noise is little, and increase disengagement gear at transitional storehouse, the impurity such as the leaf in cereal, chaff shell and flat grain can be separated, save the clearance time to cereal, and the part cereal of separation together with impurity can be reclaimed and is input to again in hopper, realization is material loading again, and the present invention tests successfully.
