An adaptive nut grading and shelling integrated device

Abstract

The invention discloses a self-adaptation grading unshelling integrated device for nuts. The self-adaptation grading unshelling integrated device comprises an upper differential speed belt, a lower differential speed belt, a front adjustment hinge, gap adjustment side plates, a rear adjustment hinge, a grading roller, an unshelling roller, an air blower and an air duct. The grading roller is located above the unshelling roller and is parallel with the unshelling roller, a certain inclination angle is formed, the gap adjustment side plates are located on the side face of the grading roller and the side face of the unshelling roller, the lower differential speed belt and the upper differential speed belt are arranged in parallel, a certain distance is formed between the two belts, and the air blower and the air duct are located below the lower differential speed belt. The functions of nut grading and unshelling and shell and nutlet separating under the action of rubbing are first integrated on the same device; during grading and unshelling, the self-adaptation grading unshelling integrated device can select suitable positions for the nuts according to the sizes of the nuts for grading and unshelling, and therefore the damage rate of nutlets during unshelling is greatly decreased. The self-adaptation grading unshelling integrated device has the advantages of being convenient to use, small in size and low in energy consumption and damage rate of the nutlets.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and particularly relates to an adaptive integrated device for grading and shelling nuts, which is an integrated device for adaptively grading, shelling and sorting nuts according to their own size based on wedge-shaped gaps. Background technique [0002] Nut shelling is an essential process for nut consumption and subsequent deep processing, and the shelling effect has a direct impact on subsequent economic benefits. Nut shelling devices at the present stage are generally divided into two categories. The first category requires prior grading of nuts, and the second category does not require prior grading. [0003] For the first type of nut shelling machine, it can only be used to shell nuts that have been graded and of similar size. Generally, manual or purchased corresponding grading machines are used for grading, but the current grading equipment is generally large in size and hi...

Problems solved by technology

[0003] For the first type of nut shelling machine, it can only be used to shell nuts that have been graded and of similar size. Generally, manual or purchased corresponding grading machines are used for grading, but the current grading equipment is generally large in size and high in price.

The current grading machines are basically graded, and nuts can only be divided into several fixed grades according to the size of the nuts. Therefore, the size of each grade of nuts has a certain range, so that the shelling process must be due to the size of the nuts. Depending on the difference, there will be some phenomenon that the nuts are damaged or cannot be shelled, and the lower the classification accuracy, the more obvious this phenomenon is.

For this type of nut shelling machine, on the one hand, the total equipment cost investment will be relatively large, and the total equipment volume will be large; on the other hand, after processing the first-level nuts, the machine needs to be adjusted to process the next-level nuts, and The shelling effect of nuts with low grading accuracy is not ideal

[0004] For the second type of nut shelling machine, it is generally guaranteed to crack the shells of nuts of different sizes, but it cannot guarantee that the nuts can quickly come out of the shelling equipment after shelling, and it is easy to cause the nuts to be shelled twice. , resulting in a high rate of fruit breakage
