Camellia oleifera fruit shell breaking, extruding and separating device

Abstract

The invention discloses a camellia oleifera fruit shell breaking, extruding and separating device. The device comprises a rack, a grading system installed on the upper left portion of the rack, a shell breaking system, a shell breaking transmission system, and a shell removing and separating system, wherein the shell breaking system and the shell breaking transmission system are installed in the middle of the rack, and the shell removing and separating system installed on the lower right portion of the rack; and the shell breaking transmission system comprises a crank sliding block transmission system and a grooved wheel transmission system which respectively control the vertical line motion of an upper cutter head and the intermittent rotation of a transposition disc. The camellia oleifera fruit shell breaking, extruding and separating device can complete diameter grading, cutting hull breaking, extrusion and hulling, vibration separation and other work at a time, efficient hulling and separation can be achieved for camellia oleifera fruits subjected to natural airing pretreatment or freshly picked camellia oleifera fruits, and the seed damage rate is reduced. By adopting the shell breaking, extruding and separating device, high shelling rate, low seed damage rate and mechanical shelling for camellia oleifera green fruits are realized through four processes of grading, cutting shell breaking, extrusion and shelling and vibration separation, and the camellia oleifera green fruits can be effectively and mechanically shelled without long-time pretreatment.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and more specifically relates to a camellia oleifera shell crushing extrusion separation device. Background technique [0002] The artificial shelling of camellia oleifera is low in efficiency and high in strength, and mechanization can realize integrated and large-scale shelling. The impact-type camellia oleifera fruit shell breaking device (Liao Pei et al. 2019) uses the high-speed rotation of the impeller to make the camellia oleifera fruit collide with the inner wall of the shell to achieve shelling; the pressure-peeling camellia oleifera fruit shell breaking machine (Wang Yanqing et al. 2019) simulates artificial fingers The peeling action uses air pressure transmission to realize peeling; the extrusion-kneading (Li Yang et al. 2015) dehulling machine uses the principle of extrusion and kneading to realize that the material is squeezed in the gap to break the shell; Camellia ...

The impact-type camellia oleifera fruit shell breaking device (Liao Pei et al. 2019) uses the high-speed rotation of the impeller to make the camellia oleifera fruit collide with the inner wall of the shell to achieve shelling; the pressure-peeling camellia oleifera fruit shell breaking machine (Wang Yanqing et al. 2019) simulates artificial fingers The peeling action uses air pressure transmission to realize peeling; the extrusion-kneading (Li Yang et al. 2015) dehulling machine uses the principle of extrusion and rubbing to realize that the material is squeezed in the gap to break the shell; Camellia oleifera fruit with cracked shell has high shelling efficiency and low seed damage rate, but it has little effect on green tea oleifera fruit

The moisture content of freshly picked Camellia oleifera green fruit is generally above 60%. With the sharp increase in planting area and output, Camellia oleifera that has not been processed for a long time is prone to breed bacteria and mildew, which will deteriorate the quality of Camellia oleifera. The shelling device (Wang Yanqing et al. 2018) is designed with a special pneumatic pushing hand claw to push the material into the occlusal blade area, and the air pressure drives the hand claw to push to realize shelling; this method can effectively shell the green tea camellia fruit directly, but the shelling efficiency is ignored and seed injury rate
