Description

Technical Field

[0001] The utility model belongs to the technical field of peanut picking and harvesting machines, and in particular relates to a peanut picking and harvesting machine with a detachable fruit-threshing roller bar. Background Art

[0002] The peanut picking harvester is a mechanical device specially used for harvesting peanuts. Its product structure mainly includes a picking device, a conveying device, a separating device and a packing device. When harvesting peanuts, the picking device will pick up the peanuts from the soil, and then transport the peanuts to the separating device through the conveying device. In the separating device, impurities and dead leaves will be separated, and the pure peanuts will be transported to the packing device for packing. The threshing roller in the peanut picking harvester is responsible for separating the peanut fruits from the peanut vines. With long-term use, it is inevitable that wear and tear and entanglement of the seedlings will occur. Therefore, the threshing roller needs to be disassembled and replaced, but the current peanut harvester is very inconvenient for the disassembly and installation of the threshing roller, which affects the maintenance efficiency.
