Roll-cutting device for tea tree stalks and cutting method thereof

Abstract

The invention discloses a roll-cutting device for tea tree stalks and a cutting method thereof and belongs to the field of agricultural machinery. The roll-cutting device for tea tree stalks comprisesa rack, an engine, a speed reducer, a fan, a leaf collecting air pipe, a leaf collecting auxiliary part, a leaf collecting fastener, a leaf collecting bag and traveling parts, and further comprises aroll-cutting moving cutter assembly and a fixed cutter; the roll-cutting cutter assembly performs rotary motion and cooperates with the fixed cutter to complete the cutting of the tea tree stalks, and the tea tree stalks can be collected into the leaf collecting bag or returned to fields according to needs. A cross-row whole-width operation mode is adopted, a row of tea trees can be pruned or picked through a single operation using the moving cutter and fixed cutter which are adaptive to the operation type and the height, width and crown shape of the tea trees to be cut, and operation efficiency is improved; the problems of great vibrations and low cutting speed of reciprocating cutting are solved, and fuel consumption, the stem tearing rate and the bud and leaf breaking rate are decreased. The roll-cutting device for tea tree stalks can be applied to tea tree shape-pruning, light pruning, deep pruning and bulk tea picking operation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rolling-cut tea tree stem cutting device and a cutting method thereof. Background technique [0002] Tea tree canopy pruning and harvesting operations are two important links in the growth and management of tea trees, both of which are realized by cutting tea tree stems. The equipment used for cutting tea tree stalks includes trimmers and tea picking machines. Most of the reciprocating double-moving knives of existing tea tree trimmers and tea picking machines are driven by crank slider mechanisms or double eccentric wheel mechanisms. When working, the reciprocating double-action knives move in opposite directions to push the tea tree stalks to the cutting edge for clamping and cutting, which cannot achieve high-speed cutting; and the stalks are bent laterally, resulting in uneven incisions and even tearing, resulting in poor cutting quality ; In addition, when ...

AI Technical Summary

Problems solved by technology

Using a tea picking machine for pruning can easily lead to tool wear and tooth breakage, while using a pruning machine for picking results in a high breakage rate of the picked green tea and a low rate of tea production, so the two machines cannot be exchanged for operations; in addition, Due to the different structures of the pruning machine and the tea picking machine, it is impossible to realize the multi-purpose of one machine by changing the knives

[0004] At present, the tea tree pruning machine and tea picking machine have narrow cutting width and low operating efficiency, cannot achieve high-speed cutting, and the friction and heat of the knives are serious; and the tea tree pruning machine and tea picking machine cannot be exchanged for operations, nor can one machine be used for multiple purposes by changing the knives.
