Multi-tangential-flow combined rape threshing, separation and stalk crushing integral device

Abstract

The invention relates to a multi-tangential-flow combined rape threshing, separation and stalk crushing integral device. The device comprises a feeding and preliminary threshing device, a main threshing device, a re-threshing device, a stalk crushing device, a clamping belt loss monitoring device and a notch board clearance adjusting device. The device is applicable to graded threshing of rape which is inconsistently matured, the threshing and separation efficiency is high, the loss is small, and notch board clearance can be adjusted in real time through a feedback system of the clamping belt loss monitoring device. The multi-tangential-flow combined rape threshing, separation and stalk crushing integral device has the advantages that not only can the agricultural mechanical and intelligent level in China be improved, but also the rape harvesting quality can be improved and the market space is wide.

Description

technical field [0001] The invention relates to a multi-cut flow combined rapeseed threshing separation and straw crushing integrated device and gap adjustment method, which are mainly used in the threshing separation part, threshing gap adjustment device and adjustment method of a full-fed rapeseed combine harvester, belonging to combined harvesting machine intelligent control field. Background technique [0002] Rapeseed is the oil crop with the largest planting area in my country. The threshing and separation device of the existing rapeseed combine harvester is mainly based on the threshing and separation principle of the rice-wheat combine harvester. The pods are fried, cracked or crushed to separate the rapeseed. Due to the large difference in the maturity and water content of rapeseed during the growth process, the material characteristics of rapeseed and stalks are very different from those of rice and wheat. During threshing and separation, there will be a phenomeno...

Problems solved by technology

The entrainment loss rate is the main index to measure the performance of the threshing separation device. The test found that the adjustment of the threshing gap is one of the key factors affecting the entrainment loss rate. The entrainment loss rate can be controlled by adjusting the threshing gap. At present, the domestic combine harvester threshing gap It mainly depends on changing the diameter of the drum for indirect adjustment. It can be seen that this method of adjusting the threshing gap not only cannot be adjusted in time, but also has a large workload and reduces the harvesting efficiency. At present, no automatic adjustment device for the threshing gap has been reported.
