Description

Cutting mechanism of swather

Technical Field

The utility model relates to the technical field of farming machinery, in particular to a cutting mechanism of a swather.

Background

A cutter-rower is a harvester with special type and purpose, which cuts down wheat straw and spreads it on the stubble to become straw strips with lap joint between head and tail, so as to be convenient for airing. The aired cereal strips are picked up and harvested by a cereal combine harvester with a pickup, and the cutter-rower can cut down wheat straws and can also be used for harvesting pasture.

The cutting and drying machine cuts the straws through the cutting mechanism, particularly, the straws to be cut are divided into bundles by a straw divider of the cutting mechanism, a cutting system of the cutting mechanism is driven by a conveying system to continuously cut the well-cut straws, the cut straws are conveyed to one side of the cutting and drying machine by conveying teeth on the cutting mechanism (the transmission of the conveying teeth of the conveying system is driven by a rotating shaft on the conveying system), and finally the straws are spread on the remaining stubbles after leaving the conveying teeth to become straw strips with overlapped tassels and tails.

In the prior art, the divider can be fixed by adopting two support rods, and during assembly, the divider is usually fixed above the two support rods after the two support rods are welded; because the number of the dividers is multiple (generally 3), the supporting condition of each divider is the same, the requirements on the welding position and the welding quality are high, the production efficiency is low, the cost is relatively increased, and once the supporting rods are welded, the adjusting space of the dividers is small, if the welded supporting rods are inclined, the dividers are difficult to adjust and meet the assembling requirements of the swather, the assembled dividers are not orderly, and the dividing and cutting effects of the swather are influenced.
