Description

Technical Field

[0001] This utility model relates to the field of harvesting machinery technology, and in particular to a harvesting device for an amphibious harvester. Background Technology

[0002] Traditional harvesters typically employ a dual-blade design with a moving blade and a stationary blade. One blade is fixed as a support base, while the other reciprocates to perform the shearing. This structure has three significant drawbacks: First, the stationary blade cannot actively participate in the shearing process, relying solely on the shearing force of the moving blade on one side, resulting in a 30%-40% reduction in cutting efficiency. Second, the stationary blade is prone to uneven wear over long-term use, forming localized indentations that further weaken the shearing effect. Third, when encountering highly resilient crops, the stationary blade cannot adaptively adjust its spacing, easily leading to jamming or missed cuts, thus affecting harvest quality.

[0003] Chinese Patent Publication No. CN208029478U discloses a harvesting device for a harvester, including a cutter, a protective cover, a drive motor, a storage box, and a conveyor belt. The cutter is housed inside the protective cover. A feed inlet is located below the cutter. A vibrator is located behind the feed inlet. A filter plate is located above the vibrator. A soil discharge port is located behind the filter plate. A water sprayer is located above the water sprayer. A mounting frame is located above the water sprayer. The drive motor is located above the mounting frame. A water tank is located behind the water sprayer. A quantity detector is located behind the water tank. The conveyor belt is located below the quantity detector. A drive wheel is located inside the conveyor belt. A moving motor is located on one side of the conveyor belt. The storage box is located behind the drive wheel. The advantages of this invention are: high production efficiency, convenient operation, low failure rate, and real-time monitoring of the harvested quantity. Therefore, it can be seen that the harvesting device of the harvester has the problem of low cutting efficiency due to the use of only one movable blade and the other fixed blade.
