Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a self-propelled pepper harvester. Background Art

[0002] Pepper is an annual or limited perennial plant of the genus Capsicum in the Solanaceae family. It can be used as a fresh vegetable or as a seasoning. Dried pepper and pepper powder are important export products in China. At present, pepper harvesting is mainly done manually, but with the increase in pepper planting area, the labor intensity and cost increase, and the low efficiency of manual harvesting increases the difficulty of factory mass production.

[0003] In recent years, pepper harvesters have been promoted to a certain extent. The existing pepper harvesters on the market are generally hand-held and still rely on manpower. In addition, the harvester needs to turn around and adjust the direction during the pepper harvesting process, which is laborious to control manually. In addition, the planting road surface is uneven, which increases the difficulty of operation and poses safety risks. At the same time, the walking system and cutting system of the existing harvester are driven in a unified manner. The engine drives the walking system and cutting system at the same time through the transmission system. However, when the harvester moves the working site, the cutting system does not need to run. At this time, the cutting system is in an idle running state, which poses a safety hazard. Therefore, in view of the above problems and technical requirements, it is necessary to improve the existing pepper harvester. Utility Model Content
