Description

Technical Field

[0001] The invention relates to the field of nut processing machinery, in particular to a walnut shelling machine. Background Art

[0002] At present, there are basically two walnut shelling schemes: the first is centrifugal collision shelling, that is, the walnut collides with the collision wall under the action of centrifugal force, and the walnut shell is knocked open by the impact force, so that the walnut kernel and the shell are separated; but this scheme will result in too many broken kernels due to the differences in the walnuts themselves, such as the thickness of the walnut shell, the inconsistent size of the walnuts and other factors, or too many walnuts will not be separated due to the reduction of centrifugal force to avoid too many broken kernels; the second method is extrusion shelling, which squeezes the walnut shell through the action of symmetrical force, causing the walnut shell to deform and break. This method will result in partial rupture of the walnut shell, and the walnut kernel cannot be completely separated from the shell; at the same time, excessive extrusion force will damage the walnut kernel, resulting in low quality of the finished product and affecting the market price.

[0003] If the above two shelling schemes want to improve the shelling effect, both require high-precision grading of the walnut raw materials, which will increase the cost of supporting equipment.

At this time, the upper shelling clamp 57 is released, and the upper walnut shell falls off the inner baffle 812 and enters the walnut shell recovery channel 11 for recovery;

[0055] 4) After the walnuts are shelled at the upper and lower ends, the walnuts are transported to the fruit picking device 6 again with the walnut shells clamped by the fixture 21. The fruit picking cylinder 61 in the fruit picking device 6 pushes the fruit picking rod 62 downward to push the walnut kernels out and collect them;

[0056] 5) After the kernel is ejected, the nut shell clamped by the jig 21 remains. The nut shell then moves along the conveyor belt 2 and enters the working area of ​​the jig opening and closing device 7. Then the jig opening and closing cylinder 7 works to insert the jig clamp 74 into the jig 21. Then the jig clamp cylinder 73 works to open the jig 21, and the walnut shell falls into the nut shell channel 11 for recovery.
