Straw plucking harvester

Abstract

The invention relates to a straw plucking harvester comprising a traction device, a transmission system, a feeding chain harrow, a straw plucking device, a scraper type conveying device, a frame, a straw tank, and a ground wheel. The traction device is arranged on the front side of the machine. The feeding chain harrow is arranged on the back side of the traction device. The straw plucking device is arranged on the back side of the feeding device. The scraper type conveying device is arranged on the back side of the straw plucking device. The straw tank is arranged on the back side of the scraper type conveying device. The straw plucking device is composed of an upper straw plucking roller, a lower straw plucking roller, and compacting devices which are arranged on the two ends of the upper straw plucking roller. Under the effect of the compacting device, the upper straw plucking roller is pressed on the upper side of the lower straw plucking device. A groove is axially provided on the surface of the upper straw plucking roller. The feeding chain harrow is composed of a chain, a toggle bar, a front feeding chain wheel, a back feeding chain wheel, and a lower feeding chain wheel. The toggle bar is arranged on the chain. The lower feeding chain wheel is coaxial with the upper straw plucking roller. The straw plucking harvester provided by the invention has the advantages of simple structure and high straw plucking rate. During working, straw alignment is not needed. With the harvester, a working requirement of whole straw plucking recovery can be satisfied.

Description

technical field [0001] The invention relates to a field straw harvesting operation machine after crops are harvested, in particular to a straw lifting and harvesting machine. Background technique [0002] After the crops are harvested, the field straw can be used for papermaking, board making, power generation, gasification and oilification after recycling. At present, the straw harvesting machinery mainly adopts the cutting harvesting method and the rod pulling harvesting method. The models used include the American USM cotton stalk extraction harvester, the KV-3.6A cotton stalk extraction harvester produced in Uzbekistan, and the 4MG-275 self-propelled cotton stalks produced by the Chinese Academy of Agricultural Mechanization Sciences. Combine harvester, 4MG-2 toothed disc cotton stalk harvester produced by Tianjin Agricultural Machinery Promotion General Station, 4MC-4 cotton stalk harvester produced by Xinjiang Academy of Agricultural Sciences Agricultural Mechanizatio...

Problems solved by technology

[0003] The field straw is divided into the surface part and the underground part. The underground part is mainly the root. At present, the harvest and utilization of straw is mainly the aboveground part. The roots of some crop straws have a high degree of lignification and have greater utilization value. too big to take advantage of
