Graded peanut huller

Abstract

The invention provides a graded peanut huller. A power device of the graded peanut huller is respectively connected with a screening device, a hulling device and a collection device; the collection device is arranged under an outlet of the hulling device and comprises three rollers and a belt and is capable of collecting and distinguishing peanuts of different sizes; the hulling device comprises a feeding hopper and a hulling drum; the hulling drum comprises an inner part and an outer part, the inner side of the hulling drum is provided with an umbrella-shaped structure connected to a shaft, the umbrella-shaped structure is of a four-link mechanism, and the outer side of the hulling drum is provided with a roller, and rubber is adhered to the inner wall of the roller; a power device is of a dual-direction rotating motor and a single-direction rotating motor; the bottom of the vibrating screen is provided with three valves; a single chip microcomputer is adopted for control; in combination with the umbrella-shaped structure, and by aiming at different species, peanuts of different sizes are fed and hulled; the control device consists of a K51 single chip microcomputer and a stepping motor. The graded peanut huller is of an adjustable umbrella-shaped structure, and is capable of not only hulling peanuts of different sizes, but also reducing phenomena of peanut breakage caused by overhigh rigidity of the roller and improving the economic benefits.

Description

technical field [0001] The invention relates to a peanut grading and shelling machine used for shelling peanuts, belonging to the field of agricultural machinery and equipment. Background technique [0002] Peanuts are known as "vegetable meat", with an oil content of up to 50%, high quality, and a delicate smell. In addition to food, it is also used in printing and dyeing and papermaking industries. Peanuts are also a traditional Chinese medicine, suitable for malnutrition, memory enhancement, spleen and stomach disorders, cough, phlegm, asthma, and lack of milk. [0003] At present, in terms of agricultural production, most of the shelling of peanuts has been done by mechanical equipment. The structure of the existing traditional horizontal peanut shelling machines is roughly similar. Its main component is an open shelling cage (shelling drum). and kneading the peanut pods to break and break the peanut pods, the broken peanut kernels and peanut shells are separated from ...

AI Technical Summary

Problems solved by technology

In this peanut shelling machine, the peanut shells are easily broken after shelling, and the shelling and shelling are easy to leak, and the efficiency is low and the effect is poor. Thoroughly, it also needs to increase the selection and separation process, the efficiency is low, the workload and cost of the user are increased, and the economic benefit is affected

Traditional peanut shelling machines are difficult to adjust the shelling gap, so the applicability to shelling different varieties of peanuts is poor

In addition, the traditional peanut shelling mechanism does not have the ability to collect peanuts of different sizes at the same time
