Volute type walnut shell breaking machine with beating rotary drum

Abstract

The invention discloses a volute type walnut shell breaking machine with a beating rotary drum, which is composed of a mainframe, and a rotating disc type feeding device, a rotary drum type beating shell breaking device, a volute type secondary striking and discharge device and a power transmission device which are installed on the mainframe. The volute type walnut shell breaking machine has the advantages that a shell breaking principle similar to cricket beating manner is adopted; in the material movement process, the beating rotary drum drives beating blades to realize primary beating shell breaking, and at the same time, a striking tooth plate is used for realizing secondary collision shell breaking; the shell breaking space is relatively free and is not limited by walnut size, the early-stage grading working procedure is omitted, and the use cost is lowered; and a volute type separated chamber design that a beating chamber is separated from a collision chamber is adopted, so that the relative integrity rate of the walnut kernel is effectively guaranteed. The volute type walnut shell breaking machine is novel in shell breaking manner, simple in structural design, reliable in operation mode and convenient for popularization and application.

Description

technical field [0001] The invention relates to a walnut shell breaking machine, in particular to a volute type walnut shell breaking machine with a pumping drum, which belongs to the field of agricultural and by-product processing machinery. Background technique [0002] my country's walnut cultivation area has reached 1.3 million hectares. With the increase of walnut production year by year, how to carry out deep processing of walnuts to increase its added value and other issues have emerged. Shelling is the first step in walnut deep processing. Due to the variety of walnut varieties, large differences in walnut size and shell hardness, and irregular shapes, manual shelling alone is difficult to meet production requirements. Therefore, the development of a stable and efficient walnut shelling machine has become a reality. It is imperative. [0003] At present, the existing walnut shell breaking machines mainly include extrusion method and percussion method in terms of wor...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned walnut shelling machine can effectively reduce labor intensity and improve the efficiency of shelling, but it also has the following disadvantages: (1) The above-mentioned shelling machine usually adopts a fixed space design for shelling, which requires that the walnuts have almost the same volume and size, and often needs to be classified by grading equipment in advance. Grading, so it is easy to be limited by the uneven size of walnuts in use; (2) The above-mentioned walnut shelling machines often have complex structural design, sophisticated supporting equipment, and various operating procedures, which virtually increase the user's initial investment, later use and maintenance costs.

[0005] The above-mentioned deficiencies limit the promotion and application of walnut shelling machinery to a certain extent, so it is urgent to develop a new type of walnut shelling machine with novel shell breaking method, good adaptability to walnut size, simple structure, low cost and easy maintenance.
