Description

Technical Field

[0001] The utility model relates to the field of agricultural harvester auxiliary devices, in particular to a garlic harvester conveyor belt conveying stem and leaf cutting device. Background Art

[0002] Rhizomes such as garlic are important vegetable crops and economic crops in my country. Taking garlic as an example, after garlic is dug, the stems and leaves need to be cut off to separate the stems and leaves from the roots. The existing stem and leaf harvester is provided with a clamping and conveying device, and a cutting device is provided at the lower part of the clamping and conveying device. The clamping and conveying device is used to clamp the stems of the rhizomes and drive the rhizomes to move. When the garlic moves to the cutting device, the cutting device cuts off the stems.

[0003] When the garlic is at too high a position, the cutting device is likely to cut the garlic when working, causing losses to farmers; when the garlic is at too low a position, the cutting device is likely to cut the stems when working, which are too high and the stems on the garlic remain too long, requiring reprocessing, reducing work efficiency and increasing costs.

[0004] The existing method of stem and leaf cutting uses a rotating knife. After working for a long time, the stems and leaves will be entangled on the rotating knife, affecting the cutting efficiency of the rotating knife, and it is easy to pull the garlic and cause damage to the garlic. In addition, the conveyor belt of the device is located above the cutting knife, and the distance between the garlic and the cutting knife cannot be guaranteed, which makes it easy for the garlic to be cut.
