Double mesh roller chestnut bract peeling machine

Abstract

The invention discloses a double-mesh roller type chestnut spiny envelope stripping machine. A feeding device is arranged at the front end of a body frame of the double-mesh roller type chestnut spinyenvelope stripping machine; an empty-envelope discharging device is arranged at the back end of the double-mesh roller type chestnut spiny envelope stripping machine; a dregs blowing device is composed of a fan, a blowing nozzle and a connecting pipe; a spiny envelope stripping device is composed of a rubbing roller, a stripping roller, an upper rubbing plate, a grinding roller, a lower rubbing plate and arc-shaped separating rods; a chestnut discharging device is composed of a trapezoidal hopper, a constant speed discharging silo, a dust removal chute and return springs; and a front deliveryoutlet of chestnuts is left between a feeding plate and the rubbing roller, and dust removal rods are designed on the oblique sides of the trapezoidal hopper. The circumferential surfaces of the rubbing roller and the stripping roller are elastic mesh surfaces woven by steel wires, without forming hard rubbing pressure on the chestnuts or causing internal injury to the chestnuts. The spiny envelopes are separated gradually when passing through the front delivery outlet, which reduces the workload of subsequent processes; the treatments of the upper rubbing plate and the grinding roller increase the separation rate of the chestnuts. The arc-shaped separating rods can complete the separation of chestnuts and spiny envelopes at one time. The constant speed silo slows down the downward speedof the chestnuts, so that the blowing nozzle can blow out crumbs from the chestnuts effectively.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing machinery, and relates to a chestnut bract peeling machine with double mesh rollers. Background technique [0002] When the chestnut bears fruit, several chestnuts are wrapped in one thorn bud. When the chestnut is mature, the thorn bud that wraps the chestnut will burst into cracks. When harvesting, the thorn bud needs to be peeled off to leave the chestnut. Because the thorns on the chestnut bracts are more prickly, it is difficult to peel off the bracts manually, and the work efficiency is low. In order to solve the problem of difficult manual peeling of thorn buds, the applicant invented a "chestnut thorn bud removal machine", patent application number: 201220677374.3, which is used to separate chestnuts from thorn buds; The device and the second-level detachment device are composed of two parts. The first-level detachment device uses an elastic mesh roller and a backi...
