Description

Technical Field

[0001] The utility model relates to a crop harvesting device, in particular to an oat harvesting device. Background Art

[0002] Not only are lodged oats inconvenient to harvest with machines, but manual handling is also too laborious and tedious. The current situation of lodged oats is as follows: For large-scale lodging, they can only be handled manually, because the oat harvesting team usually does not accept orders, and the use of existing oat harvesting equipment to mechanically harvest lodged oats will waste a lot of time. For small areas of lodging, manual support is required before machine harvesting so as not to affect mechanical harvesting; for small areas of lodging, there are currently no special small agricultural machinery on the market that can effectively harvest lodging-resistant oats. When existing small agricultural machinery encounters partially lodged oats, the oat stalks will be missed, which will increase the labor of manual intervention in the later stage; secondly, during the cutting and transportation process, the oats will be damaged, causing the oat grains on the oat stalks to fall off, thus affecting the oat harvest.
