Description

Walk-behind rape windrower

technical field

The invention relates to the technical field of crop harvesting, in particular to a hand-held windrower for rapeseed.

Background technique

my country is a big country in rapeseed planting and production, and the planting area and output of rapeseed account for a large proportion in the world. However, the traditional swathing and drying of rapeseed in my country is mainly manual operation, which has high work intensity, low operation efficiency and difficult management. Agricultural machinery related to rape production, especially rapeseed windrowing machines, account for a small proportion of agricultural machinery.

At present, the rapeseed windrowing and drying machine generally used in the market is mainly composed of a crop dividing device, a cutting device, an active guide collecting and spreading device and a transmission system. The cutting device is divided into an active grain dividing device and a passive grain dividing device. The active grain dividing device generally adopts a reciprocating cutting vertical cutting knife to separate the staggered rape stalks and divide the rape into a waiting area and a harvesting area; The passive grain dividing device is generally composed of profiling guard plates to complete the auxiliary grain dividing. The cutting device generally uses a reciprocating horizontal cutting knife to cut off the thick rape stalks through reciprocating motion, leaving a certain height of stubble and rape stalks to be laid and collected. The active guide collecting and laying device includes a reel and a lateral conveying device, etc. The reel is mainly used to actively divert the stalk flow of rape to the cutting device, lift up the fallen rape stalk and send it to the cutting device; the transverse conveying device mainly It is to transport the cut rape stalks to one side of the unit, and then carry out subsequent picking operations after drying. However, the supporting power mechanism of the existing rapeseed windrowing machine is generally refitted from the power chassis of the combine harvester or the power chassis of a small and medium-sized four-wheel tractor, and the limitations of use are relatively large. Existing horizontal conveying devices are generally composed of active conveying devices such as horizontal conveyor belts and fingers, which consume a lot of power; the existing laying forms generally adopt one-sided laying, and it is necessary to increase the walking path to complete the next cutting operation. Reduced work efficiency.
