Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a cutting platform of a wheat harvester. Background Art

[0002] A harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, and concentrates the grains in a storage bin. The grains are then transported to a transport vehicle via a conveyor belt. Manual harvesting can also be done by spreading the stalks of crops such as rice and wheat in the fields, and then using grain harvesting machinery to pick up and thresh them.

[0003] The existing wheat harvester header, such as the wheat harvester header disclosed in the utility model patent with application number 202020910713.2, has a main structure including a header body, a grain divider and a cutter. The header body is provided with a feeding channel, and also includes a feeding roller, a paddle and a driving device. The feeding roller is arranged at the connection between the header body and the conveying device and is rotatably connected to the header body. There are several paddles, all of which are connected to the feeding roller, and are used to paddle the wheat in the feeding channel to the conveying device. The driving device is used to drive the feeding roller to rotate; when in use, as the header moves forward, the wheat is cut by the cutter after passing through the grain divider, and the cut wheat enters the feeding channel and moves to the position of the feeding roller. The driving device drives the feeding roller to rotate, which can enable the paddle to paddle the material at the connection between the header body and the conveying device, so that more material enters the conveying device.
