Automatic adjustment buckwheat husking machine husking gap method and device

Abstract

An automatic adjustment buckwheat husking machine husking gap method and device comprises the steps that locking or unlocking is conducted on an upper sand disk through an electric drive pusher, a locking gear and a gear ring, and accuracy control on the gaps of an sand disk is conducted by utilizing the transmission of a stepping motor and a gear pair; the control on the gaps of the sand disk and the locking or the unlocking of the upper sand disk are totally controlled by a single-chip microcomputer; a milled rice rate image identification system is mounted on a husking machine subsequent device, when the image identification system detects that milled rice rate is reduced to below a normal range, the single-chip microcomputer will send out a control signal to enable the electric drive pusher drive the locking gear to rotate to finish unlocking, then the stepping motor drives the gear to rotate to realize the adjustment of the upper sand disk height, after the height adjustment is finished, the electric drive pusher is received a signal again to drive the locking gear to rotate to finish a locking operation, and a gap adjustment process is finished; if the milled rice rate still cannot meet the demand, and then the movements are repeated until the milled rice rate returns to the normal range. The automatic adjustment husking machine gap is realized and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and relates to a method and a device for automatically adjusting the shelling gap of a buckwheat shelling machine. Background technique [0002] The buckwheat sheller is the main equipment for buckwheat rice processing, and the sand disc sheller is the most widely used. During the use of the sand disc sheller, the shelling gap has an important impact on the rice yield. When the shelling gap is too large, the yield of buckwheat rice decreases, and the integrity of buckwheat rice is better. With the decrease of the peeling gap, the rice output rate will gradually increase, and when it rises to a certain level, it will decrease again. During this process, the broken rice increased, that is, the integrity of buckwheat rice deteriorated. When the rice yield is not within the normal range, judging whether to reduce the shelling gap or increase it depends on the buckwheat rice yield on the o...

AI Technical Summary

Problems solved by technology

However, at this stage, the peeling gap of this type of equipment still relies on manual adjustment, and the adjustment amount is mainly determined according to the operator's experience

Manual adjustment can only be carried out after the machine is shut down, otherwise it is easy to cause safety hazards
