A wind tunnel throwing and cleaning device for peanut combine harvester

Abstract

The invention discloses an air tunnel scattering cleaning device of a peanut combine. A transmission mechanism of the cleaning device is rotationally installed on a support; a roller screen is also installed on the support and rolls under the driving of the transmission mechanism; both ends of the roller screen are open, one end serves as a feeding port, and the other end serves as a discharging port; an air outlet of a fan faces the feeding port of the roller screen; a plurality of scattering plates are arranged in the roller screen and roll along with the roller screen for scattering a peanut mixture. According to the cleaning device, the roller screen rolls under the driving of the transmission mechanism, the peanut mixture is taken up by the scattering plates, scattering motion is conducted several times in an air tunnel, broken vines, stem leaves, film and other impurities in the mixture are separated out under the action of the fan, peanuts move towards the discharging port gradually, and thus the peanut cleaning work is completed. The cleaning device is simple in structure, low in manufacturing cost and high in production efficiency, so that the working time is saved, and the working cost of harvesting peanuts is lowered.

Description

technical field [0001] The invention relates to a peanut combine harvester assembly, in particular to a wind tunnel throwing and cleaning device for a peanut combine harvester. Background technique [0002] The peanut combine harvester is a combined machine specially used for peanut harvesting. It integrates seedling support, digging loose soil, pulling out seedlings, clamping and conveying, shaking soil, fruit picking, deflection screening, fan cleaning, roller chain cleaning, collection, etc. The function is integrated, the whole operation process is smooth, the operation efficiency is high, and the underground fruit leakage is less. The cleaning device of the traditional peanut combine harvester adopts the vibrating screen with the boom device driven by the crank rocker mechanism. The throughput of the vibrating screen is small, the work efficiency is low, and the impurity content is high, so it cannot complete the peanut harvesting work quickly and efficiently. Moreover...

AI Technical Summary

Problems solved by technology

The cleaning device of the traditional peanut combine harvester adopts the vibrating screen with the boom device driven by the crank rocker mechanism. The throughput of the vibrating screen is small, the work efficiency is low, and the trash content is high, so it cannot complete the peanut harvesting work quickly and efficiently.

Moreover, vibrating screens have disadvantages such as large vibration amplitude, high energy consumption, easy damage to bearings, poor reliability, complex structure, and high manufacturing costs.
