Two-stage bouncing seed and hull separation machine of camellia oleifera fruits

Abstract

The invention discloses a two-stage bouncing seed and hull separation machine of camellia oleifera fruits, and belongs to the field of camellia oleifera fruit processing equipment. The two-stage bouncing seed and hull separation machine comprises a rack, a conveying belt device, a scattered feeding device and a two-stage bouncing device. The conveying belt device is arranged on a main frame, an inclination angle is formed between the work face of a separation conveying belt and a horizontal plane, and according to the motion mode of the work face of the separation conveying belt, the work face advances from the lower end to the higher end. The scattered feeding device is arranged above the separation conveying belt in an overhead mode, and is composed of a hopper, an inclined type scattering screen, a vibration exciter and a plurality of supporting columns. The two-stage bouncing device is composed of a weak vibration bouncing device at the low position below the work face of the separation conveying belt and a strong vibration bouncing device at the high position below the work face of the separation conveying belt. According to the machine, different static friction factors, bouncing stages, rolling inertias and other physical characteristics of hulls and seeds are utilized, the separation conveying belt is beaten through the two-stage bouncing device according to the set amplitude and frequency, and the hulls and the seeds are automatically separated and respectively discharged.

Description

technical field [0001] The invention relates to a camellia oleifera fruit processing equipment, in particular to a two-stage bouncing camellia oleifera seed shell sorting machine. Background technique [0002] Camellia oleifera is a plant fruit that grows naturally, and its size and shape are all inconsistent, and the size difference is large. The characteristics of the mixture of seeds and shells formed after shelling of camellia oleifera fruit are: the shells are fibrous flap blocks with large size differences; the seeds are granular objects with inconsistent sizes and shapes with large size differences. However, some seeds and shells have similar geometric dimensions and the same weight class. Another notable feature is that the physical properties of the seeds and shells are different, such as: the coefficient of static friction, the number of bounces, and the rolling inertia of the shells and seeds are not equal. The current sorting methods of Camellia oleifera husks ...
