Peanut grading machine

Abstract

The invention discloses a peanut grading machine and belongs to the technical field of peanut grading equipment. The peanut grading machine comprises a rack, a peanut feeding device, a peanut gradingdevice and peanut collection devices. The peanut feeding device comprises a feeding chute, suspension arms and a driving structure. The peanut grading device comprises a peanut grading channel and a peanut grading strip hole, wherein the peanut grading strip hole is formed in the lower end of the peanut grading channel. The peanut grading device specifically structurally comprises two grading rollers and a grading roller driving device, wherein the two grading rollers are arranged symmetrically in the left-right direction. The grading roller driving device drives the two grading rollers to rotate in opposite directions, so that inner side arc surfaces of the upper half parts of the two grading rollers rotate from inside to outside. A gap formed between the two grading rollers which are combined together serves as the peanut grading strip hole. The peanut grading strip hole is composed of peanut grading strip hole sections of different widths. Each peanut collection device is arranged at the lower end of the corresponding peanut grading strip hole section. The peanut grading machine has the advantages that grading is conducted precisely, the universality is great, and grading holesare not likely to be blocked.

Description

technical field [0001] The invention relates to the technical field of peanut grading equipment. Background technique [0002] Peanut grading mainly includes peanut pod grading and peanut kernel grading. At present, there are two common types of peanut grading equipment, vibrating screen peanut grading machine and drum type peanut grading machine, both of which have some problems in use. The vibrating sieve peanut grading machine utilizes sieve holes of appropriate size and shape to allow peanuts of different sizes and shapes to pass through the sieve holes to complete the classification through vibration. Existing problems: 1. When using a vibrating screen to classify peanut pods, small heads of peanuts often enter the sieve holes, and the big heads get stuck in the sieve holes and cannot pass through, and the more vibrating, the tighter the sieve holes are blocked, and it is not easy to block them. clean up. 2. When using a vibrating screen to classify peanut kernels, s...

Problems solved by technology

Existing problems: 1. When using a vibrating screen to classify peanut pods, small heads of peanuts often enter the sieve holes, and the big heads get stuck in the sieve holes and cannot pass through, and the more vibrating, the tighter the sieve holes are blocked, and it is not easy to block them. to clean up

2. When using a vibrating screen to classify peanut kernels, due to the large number of grades of peanut kernels, the number of vibrating screens also needs to increase accordingly, resulting in a large machine size, a large space occupation, and a large energy consumption

Existing problems: Using cylindrical sieve grading equipment, although the peanut pods stuck in the sieve holes are separated from the sieve holes due to their own gravity and the cleaning mechanism, the problem of blockage is effectively alleviated, but the existing cylindrical sieves for grading peanuts are all efficient. Problems such as low level, serious level shifting, unreasonable cleaning mechanism, etc.

Due to the variety of peanuts in our country, both the vibrating screen peanut grading machine and the drum type peanut grading machine have the problem of poor versatility.
