Rape cutting, airing and laying machine

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a rape cutting, airing and laying machine which comprises a main rack, a chassis, a power system, a control system and a header. The chassis comprises a driving wheel and a pair of tensioning wheels which are distributed triangularly, and a plurality of thrust wheels are further arranged between the tensioning wheels. a triangular crawler belt is wound on the driving wheel, the tensioning wheels and the thrust wheels to form a triangular crawler belt type self-propelled system. A pair of transverse conveying belts is arranged at the bottom of the header, the transverse conveying belts are symmetrically distributed on the left side and the right side of the header and convey the rape in the opposite directions, a gap is reserved between the transverse conveying belts to form a rape laying channel, and a transverse header driving shaft is arranged on the rear side of the header. The two ends of the header driving shaft are in transmission connection with conveying rollers of the two transverse conveying belts respectively. The rape cutting, airing and laying machine is more suitable for operation in the environment of a hilly paddy field, and laying can be better carried out, so that airing and follow-up picking operation are facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a rape cutting and laying machine. Background technique [0002] Rapeseed is one of the important sources of edible oil and protein feed in my country. The planting area accounts for about 20% of the world, of which rapeseed in the south accounts for more than 90% of the country, and most of them are small paddy fields in hilly areas. There are various planting methods of direct seeding and transplanting. At present, the yield of my country's rapeseed machine is only 13.3%, which has become an important bottleneck restricting the development of my country's rapeseed production. Compared with combined harvesting, which has a short harvest period and is easy to cause rape siliques to burst, and the total loss rate is usually as high as 8%-10%, when the rapeseed is not fully mature, it should be cut upside down and laid out to dry before picking, threshing and cleanin...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned patent uses a crawler self-propelled system to replace the large-scale wheeled self-propelled system, but there are still the following disadvantages: the height of the chassis of the rapeseed windrower is low, and when the rapeseed with thick stalks is cut and dried in the south, the chassis will scratch until it has been laid. Neat rape stalks, thereby reducing the laying quality and making it more difficult for post-ripening and subsequent picking operations
