Large-feed-amount crawler-type cutting cross-flow multi-roller combined harvester

Abstract

The invention relates to a large-feed-amount crawler-type cutting cross-flow multi-roller combined harvester. The large-feed-amount crawler-type cutting cross-flow multi-roller combined harvester comprises a material cutting and conveying system, a threshing, separating and sorting system, a chassis traveling system, a power system and other auxiliary executing devices. A stepped cutting cross-flow multi-roller threshing and separating mode is adopted, so that crops move smoothly, the feed amount is large, and grains can be threshed, separated, sorted and collected and straw can be crushed and thrown after the crops are cut, conveyed and fed. The harvester is provided with a load test system, so that the load of main working parts when the harvester works in a field can be tested, and the acquired data are processed and analyzed by a signal receiving and processing system. A field loss detecting and material receiving device is arranged at the back of the harvester, so that materials can be received conveniently and field loss data can be acquired. According to the harvester, the harvesting requirement of large feed mount of the crops can be met, the efficiency is high, the threshing and separating capacity is high, the grain loss is low, and the field harvesting performance of the main working parts can be tested.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery manufacturing and testing, in particular to a crawler-type cross-flow multi-drum combine harvester with a large feeding volume, which can be widely used in high-performance harvesting of rice, wheat, rapeseed and other crops, and can simultaneously When working in the field, the main working parts are loaded and tested to facilitate the acquisition of field loss data. Background technique [0002] In recent years, with the continuous expansion of rice planting area, the increase of yield and the popularization of high-yield rice, it is required that the combine harvester should develop in the direction of high efficiency, high power and large feeding volume under the premise of ensuring good performance, so as to improve productivity. The threshing and separating devices with horizontal axial flow or combination of tangential flow and horizontal axial flow that currently exist on th...

Problems solved by technology

The indoor test can easily collect the materials discharged from the grass outlet, and measure the entrainment loss rate and the non-cleaning rate. However, when the combine harvester is used for field tests, the working environment is relatively harsh. How to quickly and conveniently collect the grass outlet and discharge it out? It becomes a big problem to calculate the loss rate of the materials
