Abstract
Description
Technical Field
[0001] The utility model belongs to the field of shelling mechanical equipment, and in particular relates to a concave-convex peeling roller and a coconut shelling machine. Background Art
[0002] Coconut shelling machine is a kind of shelling equipment specially designed for coconuts. It can remove the coconut shell through mechanical action, save labor and improve work efficiency. The existing application number is 201420677026.5 China Utility Model Patent Coconut Shelling Machine, and its structural diagram is as follows Figure 1 As shown, its working principle is as follows: coconuts are put into the shelling machine from the feed port A1, and a pair of peeling rollers A2 rotate relatively. Under the action of the friction baffle 3 and the peeling roller A2, the coconut rotates downward, and when it reaches the intersection of the two peeling rollers A2, the two peeling rollers A2 bite the coconut shell and peel the coconut shell. After part of the coconut shell is peeled off, the coconut is rotated and displaced as a whole by the turning device A4, and the peeling roller A2 bites another part of the coconut shell. The friction baffle 3 and a pair of round rollers 5 under the action of the spring keep the coconut pressed against the action surface of the peeling roller A2 until the whole coconut shell is peeled off, and then the unpeeled coconut is put into the shelling machine from the feed port A1. The unpeeled coconut has a large volume, which expands the space between the peeling roller A2 and the friction baffle 3, so that the peeled coconut leaks out from between the round roller 5 and the turning device A4, and the whole process is repeated.
[0003] The peeling roller used in the existing coconut shelling machine has teeth that are a number of regularly shaped rectangular plates arranged around the center of the peeling roller. The teeth do not match the shape of the coconut, resulting in a loose fit between the teeth and the coconut shell during peeling. In addition, due to the inconsistent sizes of coconuts, the turning device cannot flip the coconuts into place, resulting in poor coconut shelling effect and a lot of coconut shell residue. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a concave-convex peeling roller and a coconut shelling machine, wherein the peeling roller can fit tightly with the coconut shell, and the turning device flips the coconut into place, which is not affected by the size of the coconut and has a good coconut shelling effect.
[0005] The convex-concave peeling roller described in the utility model comprises a convex peeling roller and a concave peeling roller.

The coconut is clamped in the middle and rotates continuously under the power action of the concave-convex peeling roller and the turning device B until the entire coconut shell is peeled off. The volume of the shelled coconut becomes smaller. When a second coconut is put in, since its volume exceeds that of the shelled coconut, the space between the concave-convex peeling roller and the turning device B is expanded, and the shelled coconut falls off naturally. The peeled coconut shell is conveyed to the outside of the coconut shelling machine by a conveyor belt, and the whole process is cyclically performed.
[0009] Preferably, a concave shell scraping roller is provided on one side of the convex peeling roller, and the teeth of the convex peeling roller are in contact with the teeth of the concave shell scraping roller; a convex shell scraping roller is provided on one side of the concave peeling roller, and the teeth of the concave peeling roller are in contact with the teeth of the convex shell scraping roller.
