Description

Technical Field

[0001] The invention belongs to the field of chestnut picking, and in particular relates to a portable chestnut picking roller. Background Art

[0002] In chestnut producing areas, a lot of manpower and material resources are needed to harvest chestnuts during the harvest season. The traditional way of harvesting is to knock the chestnuts off the trees and then pick them up manually. The disadvantage of this manual picking is that a lot of manpower is required to bend over and pick up the chestnuts manually, which takes a long time, is labor-intensive, has low work efficiency, and is very easy to be injured by chestnut fluff.

[0003] Chinese utility model patent CN201383950Y discloses a chestnut picker, which avoids puncture injuries to harvesters by providing a box body with a net body. However, the picker needs to be held in the hand of the harvester at all times during harvesting, especially during the continuous movement. Although the harvester does not need to bend over, it increases the burden on the harvester's arms. In addition, during the harvesting process, since the outside of the chestnut husk is covered with fluffy spikes, some of the burst chestnut husks will be stuck at the bottom of the net body, and the harvester needs to bend over to clean them, which is not conducive to improving the harvesting efficiency of the harvester.

[0004] Therefore, how to provide a portable chestnut picking roller that is easy to move has become a problem that needs to be solved by those skilled in the art. Summary of the invention
