Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

As shown in figures 1 to 5, the invention comprises a sorting device and a peeling device, wherein the peeling device comprises a conical barrel 1 with an upward big end, two ends of the conical barrel 1 are opened, a plurality of groups of peeling units are arranged on the barrel wall of the conical barrel 1 at intervals up and down, each group of peeling units comprises two first spray heads 2 and two second spray heads 3, the two first spray heads 2 are centrosymmetric about the axis of the conical barrel 1, the two second spray heads 3 are centrosymmetric about the axis of the conical barrel 1, the four spray heads are equal in height and the inner ends of the four spray heads are all extended into the conical barrel 1, the inner ends of the two first spray heads 2 are all inclined towards the counterclockwise direction, the inner ends of the two second spray heads 3 are all inclined towards the clockwise direction, and the inclination angle size of first shower nozzle 2 is the same with second shower nozzle 3, and two first shower nozzles 2 and two second shower nozzles 3 all switch on high-pressure water source, and the pressure of the play water of two first shower nozzles 2 is greater than the pressure of the play water of two second shower nozzles 3.

The peeling device is provided with a plurality of groups, the groups of peeling devices are arranged left and right, the specifications of the conical cylinders 1 are reduced from left to right 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 rail 5 arranged along the left-right direction, a plurality of conical cylinders 1 are arranged below the rail 5 along the length direction of the rail 5, the rail 5 is composed of two side plates 6 which are symmetrically arranged, the section of the rail 5 is inverted-eight-shaped, the left end of the rail 5 is lower than the right end, the distance between the lower sides of the two side plates 6 is gradually reduced from left to right, and a blanking box 7 is arranged above the right end of the rail 5; the walnuts fall into the upper end of the rail 5 from the blanking box 7 and then roll along the rail 5 to the left end, the smaller walnuts fall into the right conical barrel 1 from the lower side of the rail 5 earlier, and the larger walnuts roll to the position close to the left end of the rail 5 and then fall into the left conical barrel 1, so that the walnuts fall into peeling devices of different specifications according to sizes to peel.

Each group of peeling units further comprises a plurality of third spray heads 8 with the circumferences uniformly distributed on the inner wall of the conical barrel 1, the third spray heads 8 are radially installed along the conical barrel 1, and the third spray heads 8 impact the walnut in the front direction to further peel the walnut.

Each first spray head 2, each second spray head 3 and each third spray head 8 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 fall down along the conical barrel 1 after falling into the conical barrel 1 from the rail 5, 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 8 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, a clockwise torque can be applied to the walnuts, because the inclination angles of the two first spray heads 2 are the same as the inclination angles of the two second spray heads 3, but the water outlet pressure of the two first spray heads 2 is greater than the water outlet pressure of the two second spray heads 3, the anticlockwise torque of the two first spray heads 2 to the walnuts is greater than the clockwise torque of the two second spray heads 3 to, under the action of the difference of the torques in the two directions, the walnuts can rotate in the anticlockwise 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, after the plurality of groups of peeling units, the green peel of the walnut is completely peeled layer by layer, and the walnut with the peeled green peel 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 two groups of high-pressure nozzles are used for peeling the walnuts in opposite directions, so that dead corners in a walnut gully can be effectively impacted, and green husks are prevented from remaining in the dead corners.
