Bract-discharging and corn-recycling device of corn husker

Abstract

The invention discloses a bract-discharging and corn-recycling device of a corn husker. The bract-discharging and corn-recycling device comprises a screening device, a pushing device and a control device, wherein the screening device comprises a vibration pulley, a recycling bin, a steel wire net and a vibration shaft; a motor drives the vibration pulley; the vibration shaft drives a cam; a cylindrical shifting shaft is arranged on the cam; the shifting shaft shifts a guide groove, so that the steel wire net connected with the guide groove is driven to vibrate; the pushing device comprises a stepping motor and a pushing rod; the stepping motor is connected with a screw rod and drives the screw rod to rotate, so that a nut slide block is pushed, and then the pushing rod pushes a pushing plate to move forward; a machine body and the pushing plate are connected by S-shaped rubber skin. Bracts husked by the bract-discharging and corn-recycling device fall onto the steel wire net under the action of gravity, corns kernels falling in a husking process fall in the recycling bin, and the stepping motor drives the screw rod to rotate to push the bracts out, so that the phenomenon that the bracts block at a discharging opening is reduced, contact between people and equipment is reduced, the bract-discharging and corn-recycling device is simple in structure and high in safety factor, and personal safety can be fully protected.

Description

technical field [0001] The invention relates to a corn peeling machine, a device for discharging bracts and recovering corn kernels, and belongs to the technical field of corn peeling machines. Background technique [0002] In recent years, my country's corn market price has risen steadily, farmers' enthusiasm for planting corn has increased year by year, and the corn planting area has continued to expand. In the Huang-Huai-Hai area, although the yield of corn machines is increasing, due to the high moisture content of the grains during harvesting, most of the harvesters do not have the peeling function to prevent the grains from being broken. Farmers rely on manual peeling, which is labor-intensive. Hence, farmers have an increasing demand for corn peeling machines. [0003] The existing corn peeling machine has basically the same general structure, and mainly includes: a fuselage, a power distribution box, active peeling rollers, passive peeling rollers, ear pressing roll...

AI Technical Summary

Problems solved by technology

The first problem is: the peeled bracts fall on the flat plate by gravity, and the bracts are manually ejected

The second problem is: none of the existing corn peeling machines is equipped with a control panel. If there is danger, the motor can only be stopped by unplugging the power supply

The third problem is: if the ears of corn are too dry, the corn kernels will inevitably peel off during the peeling process

The existing corn peeling machine is not equipped with a corn kernel recovery device, and the peeled corn kernels and bracts are mixed together, causing certain losses to farmers
