Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an adjustable reel for agricultural use. Background Technology

[0002] Harvesting machinery, used for crop harvesting, requires different serration angles depending on the crop variety and condition. Currently, reel serration angle adjustment is done manually. This is cumbersome when adjusting the serration angle after entering the field; the machine must be turned off, the operator must dismount, pull down the positioning handle, rotate the serration handle to adjust, and then reposition the positioning handle through a hole on a disc to rotate the adjustment plate, thus adjusting the reel serration angle. This manual serration adjustment method cannot adapt to different crop conditions in real time, affecting harvesting efficiency and results.

[0003] An adjustable reel, such as the one described in patent document CN210470339U, includes a reel, an adjustment device, and two transmission devices. The reel includes a fixed shaft, multiple connecting shafts, multiple spring teeth, and two discs. The multiple connecting shafts are parallel to the fixed shaft and evenly arranged circumferentially along the fixed shaft. The adjustment device includes a rotating cylinder, an adjustment shaft, and an adjustment gear. The rotating cylinder is located on the side of the disc away from the fixed shaft. One end of the adjustment shaft is connected to the output shaft of the rotating cylinder, and the adjustment gear is sleeved on the adjustment shaft. Two transmission devices are located on both sides of the reel. Each transmission device includes multiple transmission gears and a belt, wherein one of the transmission gears meshes with the adjustment gear. This design solves the technical problem that the existing manual adjustment of the spring teeth cannot adapt to different crop conditions in real time, affecting harvesting efficiency and harvesting effect.

[0004] However, the above mechanism has the following defects: First, the adjusting belt cannot be in an ideal circular state and there is no tensioning mechanism, so it is easy to fall off during operation; Second, the rotating cylinder is supported on the disc by a cantilever, and the gear at the output end needs to drive the adjusting gear to rotate, which results in a large force and instability of the rotating cylinder.
