Comprehensive crop straw harvesting machine

Abstract

The invention discloses a comprehensive crop straw harvesting machine. The comprehensive crop straw harvesting machine comprises a tractor, a picking-up and crushing device, a rotary air flow separation chamber, a forming unit, a speed change gearbox and a harvesting machine chassis, wherein the picking-up and crushing device is hung at the front part of the harvesting machine chassis, the front end of the harvesting machine chassis is connected with a traction frame, the traction frame is connected with the tractor through a hook, the speed change gearbox, a formed material bagging device and a formed material storage tank are sequentially fixed at the top part of the harvesting machine chassis from the front to the rear, and a crushed material lifting fan is connected between a discharge outlet of the picking-up and crushing device and a feed inlet of the rotary air flow separation chamber; a first power output shaft and a second power output shaft are arranged on the speed change gearbox, the first power output shaft is connected with a power input shaft of the forming unit, and the second power output shaft is connected with a power input shaft of the picking-up and crushing device. The comprehensive crop straw harvesting machine is integrated with functions of picking-up, collection, crushing, dust removal and separation and block pressing and formation, the operating efficiency and the processing quality are improved, and the number of operators and the running cost of the equipment are reduced.

Description

technical field [0001] The invention relates to agricultural machinery and equipment, in particular to a crop straw comprehensive harvester. Background technique [0002] With the improvement of living standards, civilian gas and household appliances have been widely used in rural areas, and the majority of farmers no longer use crop straw as fuel for cooking and heating. Due to the limited period of crop straw collection, and the traditional collection method is time-consuming and labor-intensive, many farmers are unwilling to collect and utilize crop straw, but burn a large amount of crop straw on the spot. Pollution of the atmospheric environment also wastes valuable renewable biomass resources. In recent years, the state and governments at all levels have intensified the ban on burning and comprehensive utilization of crop straws, investing funds and machinery and equipment to carry out the collection and utilization of crop straws. [0003] At present, most of the mec...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the mechanical equipment for collecting and processing crop stalks is transformed from animal husbandry machinery or forestry machinery, which has the following disadvantages: 1) Generally, manual collection and transfer are required first, or mobile picking and bundling machines and fixed Small mechanical equipment such as balers collect crop straw, and then gradually carry out secondary processing such as crushing and briquetting of the collected crop straw, and finally obtain solid biomass fuel. The entire production process has many intermediate links and repeated labor, resulting in crop straw The high cost of collection and processing has seriously affected the collection and comprehensive utilization of crop straw; 2) These mechanical equipment have problems of single function and low operating efficiency in the actual application process
