Description

Sorting device for shelled peanut

The utility model relates to a kind of shelled peanut classifying equipoment.

According to the requirement of outlet shelled peanut, specification that must be is in accordance with regulations carried out sieving and grading with the shelled peanut of irrespective of size.At present, mostly adopt the electronic reciprocating motion plain net sieve of multilayer during shelled peanut separating plant classification both at home and abroad, the arrangement two ends are mutually neat down on the net for this each layer of kind equipment, and working (machining) efficiency is low, and effectiveness of classification is poor, and it is also big to take up room.

The purpose of this utility model is to provide that a kind of efficient height, effectiveness of classification height, volume are little, the shelled peanut classifying equipoment of little power consumption.

The purpose of this utility model is achieved in that several layers of stepped screen cloth on box sieve nest, the discharge end of every layer of screen cloth is provided with a portable plate of changing screen cloth, the discharge end of corresponding every layer of screen cloth is provided with a discharging opening, simultaneously discharging opening is positioned at a side of sieve nest, is provided with a cleaning chamber of being made up of spacer screen, demarcation strip, screen cloth and elastomer block below every layer of screen cloth.

Screen cloth of the present utility model is owing to adopt stepped arrangement between layer and the layer, solved traditional screen cloth blanking dead angle problem of occurring of arranged vertical up and down, so can save feeding back device, by original two work that equipment is finished, have only one just passable.The efficient of an equipment is identical with the efficient of original two equipment, and that erection space has only is original 40%, and raw material save 60%, but saves energy 60% simultaneously.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structure chart according to the shelled peanut classifying equipoment that the utility model proposes;

Fig. 2 is shelled peanut classifying equipoment mesh structure figure;

Fig. 3 is a shelled peanut classifying equipoment screen cleaning device structure chart.

Describe the details and the working condition of the shelled peanut classifying equipoment that goes out according to the utility model body in detail below in conjunction with accompanying drawing.

The sieve nest 8 of this shelled peanut classifying equipoment is box, sieve nest 8 is made up of sieve nest negative, sieve nest frame 25 and sieve nest backplate 16, utilize the shaped steel screw to be installed together, install screen cloth 14 in it, screen cloth 14 can be provided with 2 to 7 layers as required, every layer of long 1-6m of screen cloth, the distance up and down of every layer of net is 3-20cm, screen cloth 14 each layers are stepped, and the vertical dislocation of adjacent two layers net is not less than 10cm, from feed end to the descending arrangement of mesh size from top to bottom of every layer of screen cloth of discharge end.Every layer of screen cloth is made up of 3-10 screen stencil sheet 28, and the discharge end of every layer of net is in the end installed replacing screen cloth trap 22 behind a screen stencil sheet 28 successively, and the flat oblique stock guide 23 and the upright oblique stock guide 24 of constant slope arranged to discharging opening.Screen stencil sheet 28, change screen cloth trap 22, flat oblique stock guide 23, upright oblique stock guide 24 and be placed on the screen cloth joist 31 in the box sieve nest 8, fastening then sieve nest set bolt 12, if screen cloth 14, replacing screen cloth trap 22, flat oblique stock guide 23, upright oblique stock guide 24 are fixed in the box sieve nest 8 and change screen clothes, as long as unclamp sieve nest set bolt 12, take out and change screen cloth trap 22, can extract screen stencil sheet 28 easily out and change.The end of sieve nest 8 is a metal material, installs 11,4 sieve nest castors 19 of connecting rod on it.Motor 13 is by belt driving band movable eccentric wheel 9, and connecting rod 11 is connected with eccentric wheel 9.Sieve nest castor 19 is put on sieve nest carriage 10, can move back and forth.Sieve nest carriage 10 is installed on the workbench 10, and it is reciprocating that motor 13 drives whole sieve nest by connecting rod 11, finishes classification work.The discharge end of corresponding every layer of screen cloth 14 all is provided with discharging opening 15, discharging opening 15 is in the side of sieve nest, can also can discharging opening be set in a side of sieve nest 8 according to need in the both sides of sieve nest 8, discharging opening 15 links to each other with discharge nozzle 20, and the shelled peanut that sorts out is transported on the conveyer belt 21 by discharging opening 15, discharge nozzle 20.Every layer of screen cloth all is provided with screen cleaning device, and screen cleaning device is made of spacer screen 29, demarcation strip 30, screen stencil sheet 28, screen cloth frame 26 and elastomer block 27, and the mesh of spacer screen is greater than the mesh of each layer screen cloth.Spacer screen 29, screen stencil sheet 28, demarcation strip 30, screen cloth frame 26 weld together; elastomer block 27 is put in the inside; elastomer block 27 can be used ball, the rubber bar elastomeric material of φ 25-35mm; in screen cloth moves back and forth; the elastomer block bump is blocked in the shelled peanut on screen cloth 14 mesh, makes its ejection, the non-blocking screen net; after adopting this device, saved the time of shutting down cleaning during use.Screen cleaning device also can be taked ball is hung over the form on the screen stencil sheet and needn't use demarcation strip and spacer screen.Be placed with screenings discharging opening 18 on the sieve nest 8, mouthful outflow thus of the off standard in the classification process.Sieve nest is provided with sieve nest backplate 16, and it adopts metal material to make, and increases the intensity of sieve nest 8.Sieve nest backplate 16 adopts screws to be fixed together with the sieve nest frame 25 of sieve nest 8 both sides, sieve nest frame 25 can adopt whole, also can adopt split, and branch body and function loose-leaf links together.

During the work of this equipment, the unprocessed shelled peanut cast hopper 1 of packing into, can control flows with hopper valve 2 when feeding intake, promote by elevator 3, pour charging aperture into, some dusts in the shelled peanut, impurity etc. utilize induced-draught fan to pass through air-suction duct 5 sucking-offs, sandstone, soil block, heavily assortedly removed, frame 7 is installed below the wind-force specific-gravity stoner 6 by wind-force stone remover 6.Shelled peanut enters in the sieve nest by charging aperture, and during shelled peanut moved back and forth in sieve nest, the shelled peanut of all size just sifted out in stipulating identical screen cloth with it, and the upper sieve mesh screen is selected big, and two layers of screen cloth take second place, by that analogy.The corresponding shelled peanut of the specification of sifting out is delivered on the corresponding conveyer belt through discharging opening, discharge pipe, has so just finished the classification work of shelled peanut.This equipment is provided with an electric appliance control box 4, the operation of control motor.The utility model is not only applicable to the classification of shelled peanut, is applicable to the classification work of other feed particulate material yet.
