Description

Portable cutter-rower

Technical Field

The invention relates to the technical field of agricultural machinery, in particular to a portable cutter-rower.

Background

The cutter-windrower is a harvester with special type and use, mainly used for cutting down wheat, rice, alfalfa, pasture and even barren weeds, taking the cut down wheat as an example, the cutter-windrower cuts down wheat straws, spreads the wheat straws on the remaining stubbles to form straw strips with lap joint between ears and tails, so as to be convenient for the grain harvesting machine for airing; the aired straw is picked up and harvested by a grain combine harvester with a pickup, and the windrower can be used for cutting wheat straw and harvesting forage grass.

However, the existing windrowers on the market basically have a gearbox for accommodating a transmission system and a lower box body only used for mounting road wheels (the lower box body is fixed on the top of the gearbox). In addition, when the transmission system of the existing cutter-rower has the functions of shifting gears (forward gear, reverse gear and neutral gear) of the travelling wheels, a large gearbox body cannot be designed to accommodate the transmission structure due to the large integral size of the transmission structure; for example, a gear box of a cutter-rower with chinese patent publication No. CN212155726U is taken as an example, in a transmission structure arranged in the gear box, in order to realize 3 gears (forward, backward and neutral) of a traveling wheel of the cutter-rower, a power input shaft, a power driven shaft, a traveling output shaft, an intermediate transmission shaft and a steering shaft are arranged, the power input shaft transmits the power of an engine into the gear box, and the power is transmitted to the traveling output shaft through the power driven shaft- > the intermediate transmission shaft- > the steering shaft (when the reverse gear is not passed through the shaft), when the power reaches the traveling output shaft, the power is decelerated by 3 stages, and the power is input to the cutter-rower head, the power is directly transmitted to the power driven shaft from the power input shaft, and finally transmitted to the cutter-rower head from a cutter-rower bevel gear set, and the process is decelerated by 1 time in the gear box. Although this kind of mode at present has realized walking wheel and has cut the speed reduction of shining the head, but the transmission system's in the gearbox structure is not compact, and the gearbox still is great, and the gearbox needs to have higher intensity, so adopt be the steel material, under the great and more condition of box of swather, the weight of swather is about 160KG basically on the existing market, and even the swather weight of lightweight is also at 120KG for swather weight is great, is unfavorable for controlling.

Disclosure of Invention

The invention aims to provide a portable cutter-rower to solve the problem that the existing cutter-rower is large in weight and not beneficial to operation.

In order to achieve the purpose, the invention adopts the following technical scheme:
