Abstract

The utility model discloses a double-blowing and double-screening peanut-hulling machine, which is mainly composed of the peanut-hulling storage of a frame and a vibration screen, wherein, the peanut-hulling storage is arranged on the upper part of the utility model; the lower part of the peanut-hulling storage is provided with a vibration granularity fanning part which uses the vibration screen as a kernel piece; a gravity fanning part is arranged on the lower part of the peanut-hulling storage; the position of the gravity fanning part is lower than that of the vibration granularity fanning part; the gravity fanning part makes a vibration screen as a kernel piece. Peanut casings and nuts are separated by the peanut-hulling storage. A first fanning is carried out under the high speed and rotary wind action of broken casing for the roller. Peanuts and nuts which fall down enter the vibration granularity fanning for carrying out a second fanning under the wind action from an upper fan. Besides, the nuts are carried out granularity screening. The nuts which fall down enter the vibration weight fanning part for selecting the nuts and removing impurities by the fan and the vibration screen.

Description

Double-blowing and double-screening peanut-hulling machine

The utility model relates to agricultural thresher machine, relates in particular to the double-blowing and double-screening groundnut sheller.

Now commercially available groundnut sheller mainly adopts the broken shell of pair roller rubbing, and blower fan is removed the shell skin, and vibration screening is produced result and the version of not plump fruit, says easily to be referred to as single wind list sieve structure.Although this groundnut sheller has solved the hardship of manual work, low to the threshing performance of peanut, to the percentage of damage height of shelled peanut, skin separates unclear with fruit.

The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of with the shelling selection by winnowing, and vibration granularity selection by winnowing and vibration and gravity selection by winnowing are the double-blowing and double-screening groundnut sheller of characteristics.

The technical scheme of double-blowing and double-screening groundnut sheller described in the utility model is as follows: double-blowing and double-screening groundnut sheller described in the utility model includes the shelling part, vibration granularity selection by winnowing part, and four parts of vibration and gravity selection by winnowing part and frame are formed.Described shelling part is basic identical with the shelling part of the groundnut sheller of prior art.The shelling part is positioned at the top of complete machine, is provided with feed hopper and charging adjustable plate.Peanut to be shelled enters in the shelling storehouse via hopper and charging adjustable plate, be provided with shelling main shaft, shelling rotor disk and adjustable shelling rotor roller in the shelling storehouse, driving the shelling main shaft by belt pulley rotates, at shelling main shaft and shelling rotor roller to turning in the journey, peanut to be shelled passes through in the middle of shelling main shaft and shelling rotor roller, be squeezed, the cot of peanut is crushed, rotate at a high speed under the effect of the wind-force that produces at blower fan and shelling rotor roller, the peanut shell is blown, shelled peanut falls naturally, enters vibration size sorting part.A fulcrum is respectively established in both sides in frame, rotates with the two axial ends of shelling rotor roller with link arm to connect, and in the middle part of link arm, is provided with shelling rotor roller and regulates bolt, is used to regulate the pair roller gap, to adapt to the shelling processing of the peanut that differs in size.Vibration size sorting partial design is below the shelling storehouse, and its core component is the vibratory sieve that can carry out the granularity screening.Shelled peanut through removing shell carries out the grade screening here, and its key is that the sieve aperture of vibratory sieve allows fruitlet benevolence to fall, and the big kernel of face is reach automatically under the vibration effect, enters discharging opening.The little kernel that falls through the vibration sieve aperture drops on the vibration and gravity wind riddle, under air blast selection by winnowing and vibration effect, removes impurity and enters discharging opening.

Use double-blowing and double-screening groundnut sheller described in the utility model, can reach in peanut shelling back and realize that secondary wind is clear.It is clear at first to carry out first time wind in shelling, promptly makes shelled peanut and peanut shell realize separating the first time under the wind-force effect in shelling; After dropping on vibration size sorting part under the shelled peanut, it is clear to carry out second time wind when vibratory sieve carries out size sorting, and the big kernel through filtering out enters discharging opening under the vibration effect of vibratory sieve; Fall on the second layer vibratory sieve through the less peanut kernels that size sorting falls, promptly drop to vibration and gravity sorting part, peanut kernels under the vibration effect of vibratory sieve, are removed impurity here through wind is clear for the third time, enter discharging opening.

Accompanying drawing is the structural representation of double-blowing and double-screening groundnut sheller described in the utility model.

4～vibratory sieve, 5～rotor roller is regulated bolt

Be described as follows in conjunction with the embodiments referring now to accompanying drawing:

Double-blowing and double-screening groundnut sheller described in the utility model, is just structurally compared with prior art distinguished as main body to some extent with frame (1).Generally speaking, double-blowing and double-screening groundnut sheller described in the utility model has two typhoon machines to have two-layer vibratory sieve to realize that peanut shelling three is clearly a characteristic with design.The version and the prior art in shelling storehouse (2) are basic identical, are installed in the topmost of double-blowing and double-screening groundnut sheller described in the utility model, and pair roller rubbing structure is adopted in broken shell.Peanut enters in the shelling storehouse (2) and make the shell fragmentation under squeezing action, and be in the wind machine and compression roller rotate at a high speed under the effect of the wind-force that is produced, and broken shell is all distinguished.Kernel through all distinguishing drops to vibratory sieve (3), promptly enter into vibration size sorting part, the sieve aperture of the vibratory sieve here (3) is bigger, purpose be to be in the wind machine blowing is carried out wind clear the time, less peanut kernels are fallen, thereby select bigger peanut kernels, can not pass through under the vibration effect, moving that the sieve aperture of vibratory sieve (3) falls, enter discharging opening than the major peanut kernel.Fall through the less peanut kernels that the sieve aperture of vibratory sieve (3) falls on the vibratory sieve (4) of vibration and gravity selection by winnowing part, when following blower fan blowing carrying out wind is clear, peanut kernels are carried out vibration screening once more, remove impurity, the peanut kernels that filter out move under the vibration effect, enter discharging opening, impurity falls to entering the impurity storehouse under the machine.
