Compared with other cutting modes, such as a hook cutter cutting type tea plucker, a spiral rolling type tea plucker and the like, the reciprocating type cutting tea plucker has better picking quality, ensures the tea quality and ensures the tea integrity rate to be 60-70%. The shearing efficiency is improved, and the time cost and the labor cost are reduced.
2. Simple structure, the tea grower of being convenient for dismantles installation and maintenance.
3. The cutting machine can cut in a certain specific direction, thereby reducing the occurrence frequency of repeated cutting and improving the cutting efficiency under the condition of minimum use.
4. The blade is made of high-quality stainless steel, so that the blade is rustproof and easy to clean, and the blade is not easy to break due to corrosion inside the blade; in addition, the blade is hard enough and is not easy to be broken.
5. Because the blade transversely cuts at a high speed when the electric tea plucking machine works normally, the blade is easy to generate vibration with larger frequency, the blade is arranged on the cutter sleeve and can transmit most of vibration frequency to the cutter sleeve, the cutter sleeve plays a good role in buffering, the strong vibration damage generated by high-speed motion is reduced, and the normal use of the blade is ensured, so that the cutter sleeve plays a good role in protecting.
6. The tail end of the cutter sleeve is fixed on the motor shell and is integrated with the electric tea plucking machine, so that the cutter is more stable, and the operation is safer.
7. The blade adopts crooked design, increases the shear plane, raises the efficiency.
8. The knife edge is changed to be small, the knife teeth are short teeth and dense teeth, the tooth surface is sharp, and the shearing frequency of the tea leaves is increased; the blade clearance ensures the tea quality.
9. The oil guide channel is used for lubricating and is convenient to maintain.
