Nut grading and unshelling device

Abstract

The invention belongs to the technical field of agricultural product processing machines and particularly relates to a nut grading and unshelling device. A device body is of a hollow box structure and consists of a grading area and an unshelling area. The nut grading and unshelling device is characterized in that the grading area consists of a conveying groove, a first cross plate arranged in the upper part of the device body, a rotary device arranged on the first cross plate and grading pipes; and the inlet end of the rotary device is communicated with the outlet end of the conveying groove, and the outlet end of the rotary device is connected with the grading pipes. The nut grading and unshelling device has the advantages that since breaking blades are provided with wedge-shaped bulges, nuts can be better extruded by the breaking blades when broken, so that larger pressure is applied onto the nuts and further the nuts are conveniently broken; and due to arrangement of the rotary device, the nuts can enter the grading pipes from the conveying groove without dead corners in the whole process, so that the nuts can not be blocked.

Description

Technical field [0001] The invention belongs to the technical field of agricultural products processing machinery. Specifically, it relates to a nut grading and shell breaking machine. Background technique [0002] Nut shell breaking machinery usually has punching type and pressing plate type. Punching-type shell breaking uses punches and abrasive tools to punch nuts with a certain pressure and spacing to achieve the purpose of shell breaking. The pressure plate type uses two parallel steel plates to squeeze each other to break the shell. The existing nut shell breaking machinery has the disadvantages that the distance is not adjustable, the speed is slow, a large amount of manpower is required, the effect and efficiency of hard shell breaking are relatively low, and the nut integrity rate is not ideal. [0003] In terms of nut classification, the prior art uses a grading barrel screen with holes of different diameters, and the rotating screen barrel achieves the purpose of clas...

AI Technical Summary

Problems solved by technology

The existing nut shelling machinery has the disadvantages of non-adjustable spacing, slow speed, and the need for a large amount of manpower assistance. The effect and efficiency of breaking hard shells are relatively low, and the integrity rate of nuts is not ideal.

[0003] In terms of nut grading, the existing technology uses a graded barrel-shaped screen with holes of different diameters on it, and rotates the screen barrel to achieve the purpose of grading. This kind of equipment has the disadvantages of high energy consumption and high noise. During the process, it is easy to cause the problem that the nuts block the screen holes

[0004] In the prior art, two different devices are often used for grading and shelling nuts. When shelling ungraded nuts is simply cracked with a shelling machine, due to the difference in nut diameter, the crushing is uneven and the crushing efficiency is low.

When using the method of grading first and then cracking the shells to process nuts, the nuts need to be graded and cracked separately. Due to the use of two sets of equipment, the energy consumption increases and the equipment installation takes up a lot of space, which brings many problems to production and use. inconvenient
