A hand-held self-propelled double row tea picking machine

Abstract

The invention relates to a hand-operation self-propelled two-row tea-leaf picker, and belongs to the technical field of agricultural machinery. The tea-leaf picker comprises a stand pipe (2) and a stand column (3) which are supported at the front side middle part and the rear side middle part of a walking chassis (1) respectively, wherein a thread pair is formed by the upper end of the stand pipe and an inner column (4); the upper end of the inner column is fixedly connected with the front side of a support frame (6) through a releasable lock catch (5); a vertical moving pair is formed by the rear side of the support frame and the upper part of the stand column; axial constrained nuts (7) driven by a lifting motor are mounted on the left side and the right side of the support frame respectively; a screw pair is formed by the nuts and a vertical lead screw (8); the lower end of the vertical lead screw is fixedly connected with a lifting frame (10) of a installation cutter (9); a collection bag is mounted on the rear lower side of the cutter; a tea bush height sensor is arranged in front of the support frame; and the sensor is connected to the controlled end of the lifting motor through a control circuit. According to the invention, coarse tuning is reasonably combined with fine tuning on the basis of coarse tuning, so that the tea-leaf picker is reasonable in structure, good in mobility and wide in application range.

Description

technical field [0001] The invention relates to tea picking equipment, in particular to a hand-held self-propelled double-row tea picking machine, which belongs to the technical field of agricultural machinery. Background technique [0002] According to the applicant's understanding, the existing tea picking machines are divided according to the operation mode, and there are single tea picking machines, double lifting tea picking machines, and self-propelled tea picking machines. However, there are the following problems: single or double tea picking machines are labor-intensive, and the operation is random. After a long time of operation, the picking height is very unstable and the quality of tea picking is poor; large self-propelled tea picking Although the machine is easy to operate and greatly reduces labor intensity, the height of tea picking needs to be manually adjusted, which is prone to under-picking or over-picking, resulting in unstable tea quality; especially, no...

[0002] According to the applicant's understanding, the existing tea picking machines are divided according to the operation mode, and there are single tea picking machines, double lifting tea picking machines, and self-propelled tea picking machines. However, there are the following problems: single or double tea picking machines are labor-intensive, and the operation is random. After a long time of operation, the picking height is very unstable and the quality of tea picking is poor; large self-propelled tea picking machines Although the machine is easy to operate and greatly reduces labor intensity, the height of tea picking needs to be adjusted manually, which is prone to missing or over picking, resulting in unstable tea quality; especially, no matter what kind of operation method, it is not suitable for high and low fluctuations Efficient harvesting of tea leaves in hilly and mountainous tea gardens

However, this institution cannot effectively solve the above-mentioned problem of tea harvesting in tea gardens in hilly and mountainous areas
