Description

An electric tea picker

technical field

The utility model relates to an electric tea picking machine, which belongs to the field of agricultural machinery.

Background technique

Mechanized tea picking is an inevitable trend in the tea production process. At present, the working principle of commonly used tea picking machines at home and abroad is basically the same. They all use reciprocating cutting knives to pick the fresh tea leaves, and then collect the fresh leaves by blowing or sweeping, so as to achieve the purpose of picking.

After retrieving a large number of patents related to tea picking machines, it was found that the existing tea picking machines generally cut the canopy directly with a cutter. During the cutting process, there is a problem of blade damage to the leaves on the same level, which not only reduces the picking quality, but also damages the canopy. The leaves of the tea tree canopy, the Chinese utility model patent CN201210242616.0 designed the upper and lower strip tooth plates to have a certain separation effect on the old leaves, but the growth direction of the leaves is upward, so the horizontal strip tooth plates cannot be pressed upwards Growing large leaves. The conveying device of the existing tea picking machine generally adopts the blowing type or the sweeping type, because the blowing type needs a large wind force to complete the transportation, so it is mostly used for the tea picking machine driven by the gasoline engine; Chinese utility model patents CN201610220433.7, CN201620975921.4 A double-bladed sweeping impeller is designed to transport the picked tea leaves. The conveying distance of this design is too short, and a small amount of tea leaves will be brought out during the rotation of the sweeping impeller. Tea leaves are poured into a collection bag. Chinese utility model patent CN201520916016.7 has designed an inclined conveyor belt behind the double-blade sweeping impeller. There is a dead angle between the front end of the conveyor belt and the sweeping impeller, which makes it difficult to transport the picked tea leaves cleanly. If the sweeping impeller is too close to the conveyor belt , It will also damage the tea leaves due to extrusion. Existing tea picking machines generally use a collection bag to be placed at the end of the machine. When a large amount of tea is picked, it will add extra burden and inconvenience to the tea pickers.
