Deep pruning machine for tea trees

Abstract

The invention relates to a deep pruning machine for tea trees and belongs to the technical field of agriculture and forestry machinery. The machine comprises a rack which is supported on a crawler-type chassis, the rack extends backwards to form a handrail, and the front end of the rack is hinged to a cutter rack through upper and lower swing rods to form a parallelogram mechanism; the cutter rackis provided with a left droop-shaped rotary-cut cutter set and a right droop-shaped rotary-cut cutter set which are driven by a power source, each rotary-cut cutter set is provided with a set of disccutters of which the diameters are gradually reduced from top to bottom, and the edges of the adjacent cutters of the left rotary-cut cutter set and the right rotary-cut cutter set are overlapped. The tea trees can be cut into multiple segments through the droop-shaped left rotary-cut cutter set and the droop-shaped right rotary-cut cutter set, ground attachment cutting can be basically achievedin theory, accumulation and blocking of branches are avoided, the agricultural technology requirement of deep pruning can be practically met, the crawler-type chassis runs smoothly, the tea trees cannot be damaged, and therefore various defects of the prior art are overcome.

Description

technical field [0001] The invention relates to a machine suitable for section-returning and covering operations, in particular to a tea tree platform mowing machine, which belongs to the technical field of agricultural and forestry machinery. Background technique [0002] Tai mowing is one of the ways to completely transform the tree canopy. Practice has shown that the heavy pruning of aging tea trees with a pruning height of 30-40cm from the ground can no longer restore the tree vigor. Even if the fertilizer management is enhanced, the yield is still not high, because the inside of the tea tree is full of thick and old branches, with a high rate of dead branches, which act as a skeleton. There are many lichens and mosses on the stems, few buds and leaves, and the branches are grayish brown. It is not enough to change the tree vigor of the tea tree without mowing. The newly drawn shoots germinate from the rhizomes after platform mowing. Their physiological age is young, an...

Problems solved by technology

[0003] For a long time, table mowers have been using traditional methods such as machetes, large scissors, etc. for manual chopping, chopping, and shearing. The operation is intensive and inefficient. Generally, 2-3 people are required to assist in the operation, and the cost is extremely high.

In recent years, although the platform mowers that have emerged are generally backpack-type garden single-disc saws, the operating efficiency has been greatly improved compared with the traditional purely manual cutting method, but two people are still required to assist in moving the cut tea trees away from the tea garden. Continuous operation, and the incision is prone to tearing, unevenness and other symptoms, and it is easy to be infected with viruses and cause the death of tea trees

[0004] According to the search, the Chinese patent application with the application number 201610323190.X discloses a kind of walk-behind side trimmer, which can be completed by adjusting the angle (0-90°) between two reciprocating cutting knives and the ground. Tea tree side and tea canopy trimming, due to the limitation of reciprocating cutter and its mechanical structure, this machine is only suitable for light, heavy and deep tea tree trimming operations, and cannot complete table mowing operations

The application number is 201711036364.5. Although the disc-type tea tree pruning machine disclosed in the Chinese patent application has been improved, it adopts a disc-type cutter arranged symmetrically on both sides. According to reports, it can realize table mowing operations; however, there are the following problems in practical application: 1) Due to the wheeled chassis and no branch guide plate, the implements can only walk in the middle of the tea row during operation, and it is very easy to hit the tea trees during the process, which will not only damage the tea trees, but also easily insert tea branches into the implements to hinder walking; 2) The use of a single-row cutter can only solve the cutting of a single cutting surface, and the cut parts will be randomly piled up on the upper, lower, left, and right positions of the machine tool. If it is stuck, the operation cannot be continued, and if it is equipped with manual assistance to remove the cut branches, the operation efficiency will inevitably be seriously reduced; 3) In particular, the adjustment range of the cutter of this machine cannot reach the 5-10cm from the ground required by the platform mowing agronomy, so It is only suitable for deep and heavy pruning, and it cannot actually meet the requirements of platform mowing
