Large-feeding-amount multi-reel-disc type sorghum ear header and sorghum harvester

Abstract

The invention provides a large-feeding-amount multi-reel-disc type sorghum ear header and a sorghum harvester. The large-feeding-amount multi-reel-disc type sorghum ear header comprises an ear shifting table, a straw smashing device and a reciprocating type cutting knife device, the reciprocating type cutting knife device is used for cutting ears shifted by the ear shifting table, and the straw smashing device is located below the ear shifting table; the ear shifting table comprises ear shifting discs, a rack rod, bearing seats, an ear shifting disc shaft, a series shaft and series shaft bearing seats; the plurality of ear shifting disc shafts are installed on the rack rod in parallel through the bearing seats, the adjacent ear shifting disc shafts are in transmission connection, and at least one ear shifting disc shaft is in transmission connection with a power device; the series shaft penetrates into any ear shifting disc shaft, the two ends of the series shaft are supported on the rack rod through the series shaft bearing seats, and one end of the series shaft is fixed on the rack rod; and the plurality of ear shifting discs are mounted on any ear shifting disc shaft. Harvestingcan be completed, completeness of ears can be guaranteed, and harvesting quality and harvesting efficiency can meet requirements.

Description

Technical field[0001]The invention relates to the field of agricultural machinery or the field of special agricultural equipment for sorghum crops, in particular to a sorghum head cutting platform and a sorghum harvester with a large feed volume and multiple reel type.Background technique[0002]Sorghum crops have a wide range of uses. They can be used for food, brewing, feeding, and bioenergy. For different purposes, the biological characteristics of sorghum are also different. On the whole, they have the characteristics of long stalks, narrow leaves, strong drought resistance and lodging resistance. For sorghum used for food and brewing, sorghum ears are the main harvest objects, so the sorghum ears grown are full and firm. In terms of planting area and planting range, the sorghum planting industry still has a great demand for ear harvest.[0003]Compared with rice, sorghum has larger plants and longer stalks. The ears are located at the top of the plant, so the ears are higher. When ...

Problems solved by technology

[0006] The above-mentioned inventions can all accomplish sorghum harvesting under specific conditions, but there are still certain problems

For the harvesting of sorghum ears, the height of the harvesting part is relatively high, and the traditional reel has a large moment of inertia during work, which eventually leads to large vibrations; some sorghum harvesters that harvest the stalks as a whole cannot guarantee the integrity of the ears. Harvesting quality is difficult to meet the needs of subsequent processing; sorghum harvesting is mainly aimed at the ear head part. When harvesting by header, harvesting stalks will increase power consumption and mechanical load, which will accelerate the loss of machine life and reduce economic efficiency; after harvesting sorghum by sorghum header , the lower stalks cannot be processed, and follow-up operations are required to remove the stalks, resulting in prolonged operation cycles and affecting subsequent planting
