Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly relates to a spiral cylinder of a wheat harvester. Background Technique

[0002] The spiral cylinder of the harvester is an important part of the harvester, especially on large harvesters, and its function is particularly obvious. The spiral cylinder is usually composed of an outer cylinder and internal spiral blades. Through rotational motion, it helps to convey the wheat in the wheat harvester to the outlet to achieve rapid grain unloading.

[0003] In view of the above related technologies, the inventor believes that when the existing spiral cylinder conveys wheat, due to the excessive amount of wheat, there will be uncut whole wheat. During the rotation process, the whole wheat will wind around the spiral shaft, thus affecting the conveying efficiency. Content of the Utility Model

The transmission mechanism is fixedly installed on one side of the spiral cylinder. The spiral mechanism is rotatably connected inside the spiral cylinder and one end extends into the transmission mechanism. The spiral mechanism includes a spiral shaft and spiral blades. The spiral blades are spirally arranged on the spiral shaft. Knife edges are provided on the spiral shaft. The cam mechanism is located inside the spiral shaft and one end extends into the transmission mechanism. The cutting mechanism is fixedly installed in the knife edges, and the cam mechanism abuts against the cutting mechanism.

[0008] Preferably, the transmission mechanism includes a housing, an input shaft, and an output shaft. An input fan blade is fixedly installed on the input shaft. An output fan blade is fixedly installed on the output shaft. One end of the input shaft is connected to the cam mechanism. One end of the output shaft is connected to the spiral shaft. The housing is filled with a fluid medium.

[0009] Preferably, the cam mechanism includes a camshaft and a cam. One end of the camshaft is connected to the input shaft. The cam is fixedly installed on the camshaft.

[0012] (III) Beneficial effects

[0013] After adopting the above technical solution, compared with the prior art, the present utility model has the following advantages:

[0014] 1. By providing the fluid medium, when the input shaft rotates, it can stir the fluid medium to drive the output shaft to rotate together.
