Description

A kind of air draught type electric windmill

(1) technical field:

The utility model relates to a kind of farm machinery, is specifically related to be used for the crops fruit and removes the air draught type electric windmill of using mixedly.

(2) background technology:

In the rural area, can once screen separation in the crops such as the paddy after drying, wheat, beans, corn, impurity such as not full cereal, ghost are screened from cereal and separate, thereby obtain full, cereal preferably.In order to reach this purpose, traditional method is that above-mentioned cereal is fallen from top to bottom, utilizes the nature wind action that a part of impurity of cereal is removed, and perhaps screens by the less sieve in aperture, this class way not only wastes time and energy, and is difficult to impurity is thoroughly removed; Another kind of way is to use old-fashioned windmill, above-mentioned cereal is poured into from the feed hopper of windmill, through the hand wooden fan of operator, the wind of agitating by fan is removed the impurity from the cereal that feed hopper leaks down, this windmill needs two people's cooperations to finish, promptly a people shakes fan, and another people sends cereal into feed hopper.Though use this windmill to use manpower and material resources sparingly than traditional method, its operating efficiency is still very low.In order to increase work efficiency, adopt the windmill of motorized motions to arise at the historic moment, as notification number is CN2838773, the name be called＜＜electric windmill utility model patent, a kind of electric windmill is disclosed, it comprises fuselage, fuselage bottom has an outlet, fuselage below organic frame, afterbody is equipped with motor in fuselage, and the motor front end is equipped with fan, the power line that motor is connected with power supply is provided with speed-regulating switch, front end at fuselage is connected with discharging opening, and the top of discharging opening is connected with feed hopper, and it is tuning in the exit of feed hopper lower end flow-control to be installed.This utility model is easy to operate, operating efficiency is higher, but the feed hopper of this utility model is installed on the discharging opening, this structure makes when the less situation of wind-force, but close together that cereal that quality heavier be blown not full for those, thereby enter discharging opening and then discharge in the lump with full cereal, thereby make in the cereal separating effect of impurity and cereal not ideal enough.

(3) utility model content:

The utility model will disclose a kind of simple in structure, air draught type electric windmill of separating good impurity removing effect.

The technical solution adopted in the utility model is as follows:

This novel air draught type electric windmill comprises air duct, and the end face of an end of described air duct is provided with fixed mount, is fixed with motor on the fixed mount, and the rotating shaft of motor is provided with fan; The air duct bottom has the outlet of two material near an end of fan, and the other end has clean material outlet; The air duct top has charging aperture with the corresponding position of clean material outlet, and charging aperture is provided with feed hopper, and the bottom of feed hopper is stretched in the inner chamber of air duct; Described charging aperture place is provided with the adjusting device that can regulate inlet amount.

Described adjusting device is arranged in the controllable register of air duct inner chamber and is positioned at the rotating shaft that can lock controllable register on the air duct by one and constitutes; One end of described controllable register is movably installed in the bottom of feed hopper, and rotating shaft is stretched in the air duct and is connected with the stiff end of controllable register, can control the inlet amount of crops by rotating shaft; Described controllable register, just can be sealed charging aperture after the locking rotating shaft when rotating shaft makes controllable register contact with the bottom of feed hopper fully greater than the size of charging aperture, prevents that with the crops that block in the feed hopper it from spilling; Rotate when rotating shaft and to make controllable register to horizontal plane when vertical, the inlet amount maximum of crops.

When the wind-force that produces at fan is big, quality heavier full crops relatively also can be scattered along wind drift one segment distance, for the full crops that prevent to scatter fall into the outlet of two material, also can on the inwall of the air duct bottom between described two material outlet and the clean material outlet, material baffle be set; The height of described material baffle can determine according to concrete needs, as when the lighter crops of screening disintegrate-quality, can select higher material baffle for use; Foreign material for lighter weight such as the ghost in the crops, careless bits, the grains of sand, handstones are then discharged from the air outlet that air duct is equipped with fan one end along the direction of wind-force.

The motor of described drive fan can be arranged on the optional position on the fixed mount, because fan is when being on the central axis of air duct, the wind-force at each position is more even in the whole wind tube inner chamber, therefore, preferably motor is located on the central axis of air duct.

When screening separated different types of crops, used wind-force size was also different, in order to reach the purpose of wind-force adjustable size, the speed regulator of control motor speed can be set on air duct also; Certainly speed regulator also can be installed in other position, as it is first-class to be installed in the line of motor and power supply.

Receive the not full crops and the full crops that obtain after screening separates for convenience, also can in described two material outlet, two material discharging openings be set, in clean material outlet, set out hopper.

The operation of this novel air draught type electric windmill is provided with support in the bottom of air duct for convenience.

The advantage of the utility model air draught type electric windmill is: simple in structure, aesthetic in appearance, can regulate the size of wind-force according to the difference of crops weight, separate the satisfactory for result of full crops and full crops not, and in the full crops that separate and not full crops, remove impurity such as grass bits in the crops, the grains of sand, ghost, handstone.
