Self-propelled plant haulm-pickup combined harvester

Abstract

The invention discloses a self-propelled plant haulm-pickup combined harvester which comprises an engine, a pickup unit, a delivering gap bridge, a feeding device, a chopping device, a throwing device and a collection box which are arranged on a self-propelled chassis, wherein the pick-up unit is connected with the feeding device via the delivering gap bridge; the outlet of the feeding device is connected with the inlet of the chopping device; the outlet of the chopping device is connected with the collection box through the throwing device; the collection box body is provided with a hydraulic turnover unit; and the engine is respectively connected with the pick-up unit, the delivering gap bridge, the feeding device, the chopping device, the throwing device and the hydraulic turnover unitthrough power. The invention has the advantages of compact structure and high harvesting efficiency, can complete the combination process of cotton haulm pickup, delivering, feeding, chopping, throwing and unloading, has strong adaptability for harvesting cotton haulms, can satisfy the demands for picking and harvesting cotton haulms in different regions, and can also be used for picking and harvesting other haulm plants.

Description

technical field [0001] The invention relates to an agricultural harvesting machine, in particular to a self-propelled cotton stalk picking combine harvester, which is mainly used for harvesting stalk plants such as cotton stalks. Background technique [0002] At present, there are three types of cotton stalk harvesting techniques available in China, namely: shovel cutting, lifting and harvesting and crushing. The structure of the cotton stalk shovel cutter is relatively simple, and the main working part is a "herringbone"-shaped shovel; during operation, the cotton stalk shovel cutter is installed in front of the tractor, and the tractor drives forward, and the "herringbone"-shaped shovel suspended at the front is sure to enter the soil. Go through deeply, thereby cutting off the cotton stalk root, and lifting the cotton stalk upwards, and some pull a rake behind, and integrate the cotton stalk into a pavement. Knife-type cotton stalk crushing harvester and front-mounted co...

AI Technical Summary

Problems solved by technology

[0003] The existing domestic cotton stalk harvesting machinery has the following problems: the cotton stalk shovel cutter consumes a lot of power, is not laid neatly, and does not have the function of chopping; The surface hardening and pulling out rate is low, and some models need to harvest in opposite rows, and the row spacing adaptability is poor; the overall strength of the traction cotton stalk harvester is not enough; the throwing knife type cotton stalk crushing harvester is inefficient; The operation is inconvenient, especially when the reverse gear is changed to a forward gear, the harvesting speed is limited and the working efficiency is low

Therefore, the existing domestic cotton stalk harvesting machinery cannot meet the requirements of high efficiency, low cost, and large-scale industrial utilization of cotton stalks as raw materials.
