When the walnut cleaning machine is used, walnuts are poured on the spiral plate 2, firstly, the motor 26 is controlled to rotate clockwise in a overlooking view angle, the fan 30 is started, the fan 30 blows air, the air enters the shell 1 from the air inlet pipe 14, then passes through meshes on the mesh baffle 29 and blows on the walnuts in the spiral plate 2 through the air outlet pipe 16, attachments on the walnuts can be blown off, then the water pipe 18 is opened, water is sprayed from the water pipe 18, mud attached to the surfaces of the walnuts can be washed off through the water sprayed from the water pipe 18, in the process, the clockwise rotation of the motor 26 can drive the rotating shaft 31 to rotate clockwise, the rotating seat 23 rotates clockwise, the rotating seat 23 can drive the filter screen 17 to rotate, the rotation of the filter screen 17 further drives the first convex blocks 3 to rotate, on one hand, the rotation of the first convex blocks 3 can increase the friction among the walnuts, make to rub between walnut and the walnut and wash, promote the effect that 18 of water pipe washed mud, on the other hand, first lug 3 also can make the walnut take place to roll in spiral plate 2, and then make every walnut homoenergetic wash by 18 of water pipe and brush, promote the clearance effect of 18 to mud on the walnut of water pipe, first lug 3 is under filter screen 17's drive simultaneously, the rotation of first lug 3 also can be smashed damaged walnut, and then make damaged walnut pass through filter screen 17 and drop, get off the effectual screening of complete walnut.

Under the clockwise rotation of the rotating shaft 31 by the motor 26, the second protrusion 33 also rotates, during the clockwise rotation of the second cam 33 with the rotating base 23, the second cam 33 will abut against the spiral plate 2, when the second projection 33 contacts the spiral plate 2, the spiral plate 2 will press the arc end face of the second projection 33, and then the second projection 33 is pressed down, so that the spring 32 is contracted, after the spring 32 is contracted, the second projection 33 smoothly slides under the spiral plate 2, on one hand, the second projection 33 can make the walnuts entering between the plate bodies of the spiral plate 2 be pulled out, on the other hand, the second projection 33 can also stir the spiral plate 2 by the rotation of the rotating base 23 driven by the motor 26, so that the spiral plate 2 vibrates, and then make spiral plate 2 can effectually prevent that the mud that is washed down on the walnut from gluing on spiral plate 2.

After the water pipe 18 washes away sludge and damaged walnuts on walnuts, the rotation of the rotating shaft 31 can also drive the scraping blade 20 to rotate, the rotation of the scraping blade 20 can effectively scrape off sewage falling on the protective shell 19 through the filter screen 17, and meanwhile, the sewage can also be effectively prevented from splashing around the shell 1 through the blocking of the blocking ring 5, in the process of clockwise rotation of the motor 26, the telescopic rod 22 extends to enable the telescopic rod 22 to be abutted against the rotating shaft 31, so that in the process of clockwise rotation of the rotating shaft 31, the ring body 21 can also be driven to effectively rotate, the rotation of the ring body 21 further enables the rotating rod 7 to rotate along with the rotation of the rotating shaft 31, further enables the rotating rod 7 to drive the scraping strip 10 and the scraping plate 9 to rotate, the scraping strip 10 rotates, and water stains on the circular table 4 can be effectively scraped in a groove between the circular table 4 and the blocking ring 5, scraper blade 9's rotation can be effectual will be scraped the garrulous walnut in the recess by doctor-bar 20 and doctor-bar 10, mud, water stain is scraped in a dirty hole 27 of play, and then through the guide of a dirty hole 27 of play, make collection box 15 can effectually be to water stain, mud and garrulous walnut carry out effectual collection, doctor-bar 10 also can effectually prevent that water stain because of long-term detention from soaking round platform 4 that leads to on round platform 4 simultaneously, and then permeate into the position department at motor 26 place, the effectual guard shield 19 that has promoted to motor 26, doctor-bar 20 can also scrape down the water stain on the guard shield 19 simultaneously, in the department of running through of axis of rotation 31 and guard shield 19, rotate the centrifugal force that produces and doctor-bar 20 scrape through axis of rotation 31, water stain can not be detained on guard shield 19.

After the walnuts are cleaned, the water pipe 18 is closed, the motor 26 is controlled to rotate anticlockwise, when the motor 26 rotates anticlockwise, the telescopic rod 22 is contracted, at the moment, the output of the motor 26 cannot be dispersed by the rotating rod 7, the scraper plate 9 and the scraping strip 10, after the water pipe 18 is closed, the air outlet pipe 16 continuously blows air under the action of the fan 30, at the moment, the air blown to the filter screen 17 by the fan 30 can promote the drying of the walnuts, so that the walnuts can be quickly dried, the motor 26 rotates clockwise, so that the walnuts are effectively rotated in the spiral plate 2 under the action of the centrifugal force of the filter screen 17, in the process, the first convex blocks 3 can also effectively stir the walnuts to the side edges of the spiral plate 2, the walnuts are effectively promoted to enter the spiral plate 2, the second convex blocks 33 can also effectively stir the walnuts to the first conveyor belt 8, and then the walnuts are conveyed by the first conveyor belt 8 one by one another, second lug 33 and first lug 3 stir and filter screen 17 rotates produced centrifugal force, can effectually scatter the walnut for the walnut can not pile up the conglobation when entering into on first conveyer belt 8, can make things convenient for the walnut to dry naturally on the one hand, and on the other hand also can make the walnut be single when entering into in the box 6 and get into.

After the walnuts enter the box body 6, the air blowing of the fan 30 can enable the walnuts to float upwards, due to the fact that the surfaces of the walnuts are uneven, when the fan 30 blows the walnuts, the walnuts can also rotate, the surfaces of the walnuts can be blown uniformly by the rotation of the walnuts, water stains on the surfaces of the walnuts can be blown to be dried quickly by the air, the drying effect on the walnuts is further promoted, the walnuts can impact on the obliquely arranged mesh baffle 29 under the blowing of the fan 30, the walnuts can move towards the direction of the second conveyor belt 11 after impacting on the mesh baffle 29, the positions where the walnuts fall are different according to different weights of the walnuts, the walnuts of different specifications can fall on different tracks which are cut by the partition plates 12 on the second conveyor belt 11, the walnuts are effectively screened for the second time, and the walnuts of different specifications are screened out, meanwhile, when the walnuts pass through the discharge hole 13, the walnuts are effectively counted through the counter 28, and the single walnuts enter the box body 6, so that the blowing effect of the fan 30 can be enlarged, and the counting of the counter 28 can be facilitated.

The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching.
