Drum type macadamia nut screening machine

Abstract

The invention aims to provide high-efficiency and convenient practical innovative equipment for accurate classification according to diameter size for macadamia nut screening and classification. The structural form, the working principle and the design idea of a drum type macadamia nut screening machine are described through the specification and attached drawings in detail. The machine mainly comprises a speed reducer adjusting seat 1, a driving mechanism 2, a transmission mechanism 3, a safety protective cover 4, a feeding hopper 5, a drum screen 6, a shell 7, an end cover 8, a drum supporting bearing 9, a discharge hopper 10, a rack 11, an observation window 12 and the like. The working principle and the working process of the machine have two core contents and processes: 1, a material does axial feeding motion along a drum; and 2, the material is screened and classified in the relatively closed drum. The material enters the drum form the feeding hopper 5; and since the straight or bent stirring rod material guide plates which are spirally distributed are distributed on the inner surface of the drum, the material does rotary feeding motion along the drum under the actions of drum rotation and the stirring rods. Since two kinds of circular holes with different diameters, which are uniformly distributed in the surface of the drum, are formed in the surface of the drum of the inner layer and the outer layer, screening and classification of the material are simultaneously finished during feeding motion of the material.

Description

technical field [0001] The drum-type macadamia nut screening machine of this project belongs to the high-tech products of new crop processing technology and equipment in the field of national opto-mechanical integration→new mechanical products→special agricultural and forestry equipment. Background technique [0002] Macadamia is a new kind of fruit tree. Due to its high nutritional value and health value, the international market has always been optimistic, and the price is expensive. All countries in the world in suitable planting areas are actively introducing large-scale planting. [0003] Among them, Australia and the United States are the largest producers in the world, while Brazil, Kenya and Costa Rica are the fastest growing countries in the near future. [0004] The types of crops planted in my country rank among the top in the world, among which shell fruit crops account for a considerable proportion. Common shell fruit materials include: ① Nuts, such as macadami...

AI Technical Summary

Problems solved by technology

[0009] For example, Yingjiang macadamia nuts are a well-known fine variety throughout the country, but most of the industry is still in the primary stage of raw materials, and most of the processing is family workshops. The scale is small, the technology is backward, and the technology content is low. It is difficult to participate in domestic and international competition and drive Development of Macadamia Nut Industry in Yunnan
