Abstract

The utility model relates to a grain drying machine with a grain cleaning device. A sundries collection hopper is arranged below a grain discharging segment and a screening hopper formed by a screening slice is sleeved in the sundries collection hopper, a clearance is present between the screening hopper and the sundries collection hopper. A dust suction tube is mounted in the space above the inner part of the screening hopper and dust suction ports are opened at the two sides of the dust suction tube and on the lower surface and the dust suction tube is connected with a dust remover by a dust removal tube. The dries grain is placed in the screening hopper and slides down along the screening slice and then is discharged from a grain outlet at the lower part of the screening hopper; the sundries are screened by the screening slice and fall down into the sundries collection hopper and then are discharged from the lower port of the dust remover; thus the air is purified and discharged from the upper port of the dust remover and grain is cleaned.

Description

A kind of grain drying machine with cleaning mechanism

Affiliated technical field

The utility model relates to a kind of grain drying machine with cleaning mechanism, especially can clear up the solid food before going out machine in oven dry cereal.

[affiliated technical field: should point out under the technical solutions of the utility model or direct applied technical field.]

Background technology

At present, known grain drying machine is made up of grain storage section, oven dry section, cooling section, grain discharging section, air-heater, air-cooler and some auxiliary equipment such as elevator, crop inlet pipe etc.Rise in the dryer with the elevator grain that will wet, the hot-air seasoning that wet grain is sent here by air-heater through grain storage section, oven dry section the time, the cold wind of being sent here by air-cooler during through cooling section cools down grain, to grain discharging section grain is discharged outside the machine.Grain advances dryer and all tentatively cleans as last, but since tentatively clean machinery to clean quality extensive, also be mingled with in the wet grain or adhering to impurity such as some particles, earth, dust, chaff skin, in drying course, these impurity are also dried and are separated from the grain grain, for guaranteeing grain quality, also will be supporting more multiple clear and some conveyings or lifting means, once clear up again drying by the fire back grain, being directed at equipment investment like this increases, floor space strengthens, the technological process complexity, and operating cost strengthens.

Summary of the invention

In order to overcome the deficiency that existing dryer itself can not be cleared up grain, the utility model provides a kind of grain drying machine with cleaning mechanism, this grain drying machine can not only be dried grain, and can clear up drying by the fire back grain simultaneously in the oven dry operation, saved compound clear link, simplify technology, saved investment, reduced and take up an area of, reduced operating cost.

The technical scheme that its technical problem that solves the utility model adopts is: below the grain discharging section (10) of grain drying machine, the assorted bucket of collection is installed, suit a screening bucket of being made by the sieve sheet in the assorted bucket of collection, leave the space between the assorted bucket of screening bucket and collection, in the space of screening bucket inner and upper, a sweep-up pipe is installed, the sweep-up pipe both sides have suction port below reaching, and with cleaning shaft sweep-up pipe and deduster are coupled together.Its course of work is: the grain after the oven dry is discharged in the screening bucket and along the sieve sheet and slips down, grain is from mouthful discharge of putting out cereal of screening bucket bottom, impurity is then screened out to drop in the assorted bucket of collection by the sieve sheet and discharges from impurity outlet, light impurities such as some chaff skins and dust then suck sweep-up pipe from suction port, enter deduster through cleaning shaft again, light impurity is discharged from the deduster end opening under the effect of the centrifugal dust-removing of deduster, and air is cleaned the back from deduster discharge suitable for reading, and grain is cleared up.

The beneficial effects of the utility model are, can clear up grain when grain drying machine is dried grain, have saved multiple clear link, simplified technology, save investment, have reduced and take up an area of, and reduce operating cost, reduce the pollution of dust to environment.

The specific embodiment

In Fig. 1, the assorted bucket of collection (4) is installed below the grain discharging section (10), the assorted bucket of collection (4) is up big and down small, the side's of being taper, manufacture with the 2mm steel plate, below the assorted bucket of collection (4) impurity outlet (1) is arranged, the impurity that screens is discharged from impurity outlet (1), in the assorted bucket of collection (4) inside screening bucket (5) is installed, screening bucket (5) and collection be assorted to struggle against and leaves the 60mm space between (4), the wall of screening bucket (5) is made with the sieve sheet (19) of steel plate punching, sieve sheet (19) can be changed according to the needs of grain variety screening, put out cereal below the screening bucket (5) mouthful (3), the impurity that screens falls into the assorted bucket of collection (4) and discharges from following impurity outlet (1), and sweep-up pipe (8) also is equipped with in the top position in screening bucket (5), about the tube wall of sweep-up pipe (8) and below have suction port (18), one end of sweep-up pipe (8) seals with steel plate, and the other end is connected with cleaning shaft (9), and the other end of cleaning shaft (9) is connected with deduster (6).

Claims

1. grain drying machine with cleaning plant, it is characterized in that: below grain discharging section, the assorted bucket of collection is installed, suit a screening bucket of being made by the sieve sheet in the assorted bucket of collection, leave the space between the assorted bucket of screening bucket and collection, in the space of screening bucket inner and upper, a sweep-up pipe is installed, is had suction port below the sweep-up pipe both sides reach, sweep-up pipe and deduster are coupled together with cleaning shaft.
