The peeling device is provided with a plurality of groups, the specifications of the conical cylinders 1 of the peeling devices are reduced in an equal ratio, and the lower end of each conical cylinder 1 is provided with a collection box 4.

The sorting device comprises a plurality of horizontal circular screening discs 5, each screening disc 5 comprises a disc bottom and a side wall, the screening discs 5 are coaxially arranged from top to bottom, the number of the screening discs 5 is one less than that of the conical cylinders 1, a blanking box 6 is arranged above the uppermost screening disc 5, screening holes 7 are densely distributed in the disc bottom of each screening disc 5, the larger the aperture of the screening holes 7 on the screening disc 5 which is closer to the uppermost screening disc is, a side hole 8 is formed in the side wall of each screening disc 5, a rotating shaft 9 penetrating through the screening discs 5 is arranged at the axis of each screening disc 5, two scraping plates 10 fixed on the rotating shaft 9 are arranged in each screening disc 5, the lower end of the rotating shaft 9 is connected with a driving motor 11, the driving motor 11 drives the rotating shaft 9 to rotate and stir walnuts in the screening discs 5, the walnuts smaller than the diameter of the screening holes 7 fall from the screening holes 7, the walnuts larger than the diameter of the screening holes 7 are gradually pushed to the outside by the scraping plates 10 and finally discharged from the side holes 8, the walnuts discharged from the side holes 8 fall into the conical cylinders 1 of corresponding models according to the diameter, and the walnuts discharged from the screening holes 7 of the screening disc 5 at the lowest layer fall into the conical cylinder 1 of the minimum model.

Every screening dish 5 the side opening 8 and the toper section of thick bamboo 1 that corresponds between all be equipped with slide 12, side opening 8 exhaust walnut through slide 12 fall into corresponding toper section of thick bamboo 1 in, also be equipped with a slide 12 between the toper section of thick bamboo 1 of the below minimum model of below screening dish 5, the walnut falls into the toper section of thick bamboo 1 of minimum model through slide 12 after falling from screening hole 7 of lower floor.

Each group of peeling units further comprises a plurality of third spray heads 13 with the circumferences uniformly distributed on the inner wall of the conical barrel 1, the third spray heads 13 are radially installed along the conical barrel 1, and the third spray heads 13 impact the front side of the walnut to further peel.

Each first spray head 2, each second spray head 3 and each third spray head 13 are inclined upwards, an upward component force can be applied to the walnuts, the falling speed of the walnuts is reduced, and peeling is more thorough.

When the walnut peeling machine works, walnuts to be peeled fall into the uppermost screening disc 5 from the blanking box 6, the driving motor 11 drives the scraping plates 10 to rotate through the rotating shaft 9, the walnuts in the screening disc 5 are stirred by the scraping plates 10, the walnuts smaller than the diameter of the screening holes 7 fall from the screening holes 7, the walnuts larger than the diameter of the screening holes 7 are gradually pushed outwards by the scraping plates 10 and are finally discharged from the side holes 8, the walnuts discharged from the side holes 8 fall into the conical cylinders 1 of the corresponding models according to the diameter size through the slide rails 12, the walnuts discharged from the side holes 8 of the uppermost layer fall into the conical cylinder 1 of the largest model, the walnuts discharged from the side holes 8 of the second layer fall into the conical cylinder 1 of the second large model, and the rest is done in sequence, and the walnuts discharged from the screening holes 7 of the screening disc 5 of the lowermost layer fall into the.

After the walnuts fall into the conical barrel 1, the walnuts fall along the conical barrel 1, when the walnuts pass through the first group of peeling units, high-pressure water flows sprayed by the two first spray heads 2, the two second spray heads 3 and the plurality of third spray heads 13 impact the walnuts for peeling, meanwhile, because the two first spray heads 2 incline towards the anticlockwise direction, the high-pressure water flows of the two first spray heads 2 can apply anticlockwise torque to the walnuts, similarly, because the two second spray heads 3 incline towards the clockwise direction, the two second spray heads 3 can apply clockwise torque to the walnuts, because the water outlet pressure of the two first spray heads 2 is the same as the water outlet pressure of the two second spray heads 3, but the inclination angle of the two first spray heads 2 is different from that of the two second spray heads 3, the tangential component force of the first spray heads 2 and the second spray heads 3 is different, and therefore, the two first spray heads 2 and the second spray heads 3 can generate clockwise or anticlockwise torque difference to the walnuts, under the action of the torque difference, the walnuts can rotate towards the corresponding direction, so that the walnuts are peeled comprehensively.

The torque difference of the two groups of high-pressure water flows is utilized to drive the walnuts to rotate, but the torque of the water flows is not directly utilized to drive the walnuts to rotate, because if the walnuts are driven to rotate by using the unidirectional water flows, the walnuts can rotate at a high speed along with the water flows, the relative speed between the walnuts and the water flows is small, the impact force of the corresponding water flows is small, and the walnuts idle at a high speed and cannot be peeled; the torque difference of the two groups of high-pressure water flows is utilized to drive the walnuts to rotate, so that the walnuts rotate at a slower speed while the two groups of high-pressure water flows have higher pressure, a higher relative speed is kept between the walnuts and the water flows, the impact force of the water flows is large, and the walnut green husks are effectively peeled off;

the diameter of the walnut is reduced along with the peeling of the outer green peel of the walnut, the walnut moves towards the lower end of the conical barrel 1, the next group of peeling units peels the walnut again, after the plurality of groups of peeling units, the green peel of the walnut is completely peeled layer by layer, and the walnut after peeling falls into the collection box 4 from the lower end of the conical barrel 1.

The invention has the following beneficial technical effects:

1. the walnut peeling machine peels walnuts one by one, so that the walnuts can be prevented from being lost and leaked;

2. when the high-pressure water flow is used for peeling, the walnut autorotation is adjusted in position by using the torque difference of the water flow, so that the comprehensive peeling is realized;

3. the walnut is rotated by utilizing the torque difference of the two groups of high-pressure water flows, so that the walnut is rotated at a slower speed while the two groups of high-pressure water flows have higher pressure, a higher relative speed is kept between the walnut and the water flows, the impact force of the water flows is large, and the walnut green husks are effectively peeled off;

4. the first spray head 2 and the second spray head 3 are used for peeling the walnuts in opposite directions, so that dead corners in a ravine of the walnuts can be effectively impacted, and green husks are prevented from remaining in the dead corners.
