Half-feed-type harvesting machine with rubber strip teeth

Abstract

The invention discloses a half-feed-type harvesting machine with rubber strip teeth, which comprises a header, threshing teeth which are arranged on a threshing drum, and a rice straw conveying chain in a rice conveying mechanism. The half-feed-type harvesting machine with the rubber strip teeth is characterized in that the threshing teeth are the rubber strip teeth, the arrangement structure of the rice straw conveying chain is triangular, the half-feed-type harvesting machine additionally comprises a straw cutting roller, the straw cutting roller is arranged at the rice straw output part of the header, the straw cutting roller is connected with a power mechanism, and a straw discharge chain wheel which is assembled with the rice straw conveying chain is a wide-tooth wheel. The half-feed-type harvesting machine with the rubber strip teeth has the advantages that the manufacturing process of the rubber strip teeth used as the threshing teeth is simple, the quantity of used steel materials is decreased, the accessories of the harvesting machine are decreased, the weight of the entire machine is reduced, the driving power is relatively improved, the grains are thoroughly threshed, the rice straw is not damaged and can be treated through the straw cutting roller, and the manpower and material resources are saved; and since the arrangement structure of the rice straw conveying chain is triangular, the linear distance of a threshing process is reduced, the conveying distance of rice ears is reduced, the threshing process can be completed within short linear distance and the entire machine is more compact.

Description

Technical field [0001] The invention relates to agricultural machinery, in particular to a semi-feeding harvester with rubber splines. Background technique [0002] In the existing semi-feed harvester, the threshing teeth provided on the threshing barrel are made of metal materials, usually made of steel or iron materials. The amount of steel materials is large and the weight of the whole machine is heavier. It needs to provide a larger driving force. Moreover, there are disadvantages of easy damage to the straw and unclean threshing. At the same time, the rice stalk conveyor chain in the rice delivery mechanism is linear, the straight line distance of the threshing process is long, and the transport distance of the rice ears is long, which is not conducive to the harvester Whole machine design. Summary of the invention [0003] The purpose of the present invention is to address the shortcomings of the prior art, and provide a semi-feeding harvester with rubber splines. The harve...

Problems solved by technology

[0002] In the existing semi-feeding harvester, the threshing teeth on the threshing cylinder are made of metal, usually made of steel or iron. The amount of steel material is large and the weight of the whole machine is heavy, so it needs to provide a large driving force. And there is the shortcoming that easily damages rice straw, threshing is not clean; Simultaneously, the arrangement structure of the rice stalk conveying chain in the rice sending mechanism is linear, the linear distance of threshing process is longer, and the conveying distance of rice ear is longer, is unfavorable for harvester Machine design
