Abstract

The utility model relates to a grain drying machine with high dust removing effect the left side of the machine body is provided with a lifter and an air heater; the lower part of the right side is provided with an exhaust blower; a drying layer is formed by the air heater and the exhaust blower; the grain can be conveyed upwards by a lift machine and is conveyed into the machine body through a screw conveyer; air convection ports are arranged on one side of the lift machine and one side of the conveyer; a material sifting plate is arranged on the screw conveyer; the sundries of dust straw, bad grain, etc. are carried out the winnowing following with airflow and are discharged by a dust emission machine. The utility model can prevent the sundries from clogging the exhaust blower or the air heater; the negative pressure function in the machine body can be suppressed.

Description

Grain drying machine with high dust removing effect

The utility model relates to a kind of crop dryer with high dust removing effect, belongs to the technical field of crops drying equipment.

The present crop dryer that uses, owing to produce negative pressure in the body, the dust discharge effect is reduced, and foreign material such as the dust of light weight, rice stalk and bad cereal are difficult for getting rid of, can cause internal heat blower fan and exhaust blower to stop up especially dust and intersperse among among the air also contaminated environment, influence workers ' health.

The purpose of this utility model is that a kind of crop dryer with high dust removing effect will be provided, and it can overcome above-mentioned shortcoming, and original mechanism has been done improvement, sets up the cross-ventilation mouth on the body of lift and auger conveyor one side.Set up switch-plate in addition, make impurities and dust be easy to discharge.Can significantly improve the dust discharge effect thus.

The purpose of this utility model is to realize like this, on the basis of original drying machine, on the body of lift and auger conveyor one side, set up the cross-ventilation mouth that has many micropores, the required air quantity of dust cleaning machine of supply drying machine can improve the dust discharge function, installs a switch-plate additional in the appropriate location of auger conveyor in addition, when conveyer turns round, cereal stirred stir, impurity such as dust, rice stalk are raised to come-up, go out outside the body with the air band ejectment of inflow.

The profile schematic diagram of the former crop dryer of Fig. 1

The former crop dryer part-structure of Fig. 2 schematic diagram

This crop dryer of Fig. 3 contour structures schematic diagram

This crop dryer of Fig. 4 part-structure schematic diagram

Now in conjunction with the accompanying drawings the structure of crop dryer is described in detail:

By Fig. 1, a lift (10) is equipped with in the outer left side of the body of crop dryer (1), can upwards carry cereal, air-heater (13) is equipped with in the below, left side, the below, right side is equipped with an exhaust blower (12) accordingly, both make drying layer of the inner formation of body (1), can carry out drying to cereal.

Fig. 2 is a drying machine part-structure schematic diagram.

The appropriate location of lift (10) links to each other with a flat spin conveyer (11), cereal changes when upwards carrying by auger conveyor (11) through lift (10) sends into body (1) inside, carry out drying operation, owing to often have a large amount of dusts and rice stalk in the cereal, and impurity such as bad cereal, as untimely removing, not only can cause body (1) internal heat blower fan (13), exhaust blower (12) stops up, and after drying cycles is finished cereal when going out paddy funnel (14) and locate outwards to carry, it is boundless and indistinct among air often to cause a large amount of dusts to fly upward, workman and surrounding environment are all caused bad influence, make cereal need carry out the dust discharge sorting operation in addition through super-dry, add in the right-hand member top of conveyer (11) for this reason and adorn a dust cleaning machine (15), to get rid of its dust,, be difficult to get rid of bad cereal because dust-exhausting quantity is limited, do not have the function that sorts, need further improvement.

Fig. 3 is this crop dryer contour structures schematic diagram.

Set up a cross-ventilation mouth (22) that has many apertures in lift (20) top, on a side body of auger conveyor (21), set up a cross-ventilation mouth (23) that has many apertures in addition, make air flow into body (2) top through this.

Fig. 4 is the part-structure schematic diagram of this crop dryer.

Motor (14) is contained in the upper right side of body (2), belt pulley (25) is housed on the motor shaft to be connected with belt pulley (27) on being contained in auger conveyor (21) axle right-hand member axle by belt (26), paddy funnel (4) is equipped with out in conveyer (21) lower left, the upper left side is lift (20), set up a dust cleaning machine (3) in the top of conveyer (21) again, be contained on the body (2), because on-stream generation static pressure of drying machine and air quantity, make to produce negative pressure in the body, can influence its dust discharge effect.The dust cleaning machine of setting up in this drying machine (3) institute required airflow no longer is subjected to the influence of negative pressure in the body by cross-ventilation mouth (22), (23) supply, therefore can significantly improve the dust discharge effect.Add in the appropriate location of auger conveyor (21) again and adorn a switch-plate (5), when conveyer (21) turns round, can stir cereal and stir, the impurity such as dust, rice stalk and bad cereal of light weight are raised to come-up, pass through the cooperation of cross-ventilation mouth (22), (23) again, with the guiding that flows into air, discharge body (2) outside via dust cleaning machine (3).

Compared with prior art, this crop dryer has following advantages:

1, the body of executing conveyer one side at lift and spiral shell arranges the cross-ventilation mouth with many holes, supplies thus dust cleaning machine required air quantity, can make drying machine no longer be subjected to the impact of negative pressure, improves its dust discharge effect.

2, set up a switch-plate at the auger conveyor place, impurity such as dust, the rice stalk of lightweight and good cereal are stirred raise, be with ejectment to go out outside the body with the wind to come-up.

3, do not pollute surrounding environment.

4, make that air-heater and exhaust blower are unlikely to be stopped up by foreign material.

Claims

1, a kind of crop dryer with high dust removing effect, lift is equipped with in its body left side, a drying layer is formed by the exhaust blower on air-heater and right side in the below, left side, it is characterized in that setting up a cross-ventilation mouth (22) in lift (20) top, on auger conveyor (21) one side bodies, set up a cross-ventilation mouth (23) again, also install a dust cleaning machine (3) in conveyer (21) top, locate to add at conveyer (21) and adorn a switch-plate (5).
