The grape industry is a labor-intensive industry. In recent years, with the rapid development of industrialization and urbanization, a large amount of agricultural labor has been transferred to the secondary and tertiary industries. The labor cost of grape production has increased significantly, which directly affects the economic benefits of the grape planting industry. Therefore, , the grape industry has more and more urgent demand for production management mechanization technology and equipment, and production mechanization has become an inevitable requirement for the sustainable development of the grape industry.

In my country's grape-producing areas, the labor cost of new shoot management such as main and auxiliary shoot pruning accounts for about 1/3 of the total cost of grape production and management. very urgent. At present, the reciprocating tip cutting machine and the fixed rotary tip cutting machine developed by research institutes and enterprises such as the Institute of Fruit Trees of the Chinese Academy of Agricultural Sciences and Gaomi Yifeng Machinery Co., Ltd. have solved new problems such as pruning of primary and secondary shoots in vertical leaf curtain vineyards. However, at present, the area of vertical leaf curtain vineyards in my country is less than 1/3, and more than 2/3 of horizontal leaf curtain and V-shape leaf curtain vineyards still use new shoot management such as primary and secondary shoot pruning. Manpower has seriously affected the mechanization level of new shoot management such as pruning of main and auxiliary shoots in vineyards in my country. Therefore, it is urgent to develop a method that is suitable for vertical leaf curtain vineyards, and is also suitable for main and auxiliary shoots of vineyards with horizontal leaf curtains and V-shaped leaf curtains.

The structure of the cutter: a swing cylinder is installed on the fixed bracket, and an electromagnetic reversing valve is installed on the swing cylinder. The swing cylinder is connected with the telescopic cylinder through a connecting shaft. Box lifting bracket, the rotary hydraulic motor is installed on the rotary transmission box lifting bracket, the rotary hydraulic motor and the rotary transmission box power transmission, the cutting knife driving hydraulic motor is installed on the upper part of the rotary transmission box lifting bracket, and the cutting knife driving hydraulic motor is installed on the cutting knife On the support, a power transmission belt pulley is housed on the cutter support, and a cutter shaft mounting seat is fixed, a blade is housed on the cutter shaft mounting seat, and a cutter shield is housed on the cutter support.

The power output by the tractor is transmitted to the transmission box of the oil pump through the transmission shaft, and the dual high-pressure oil pump is driven to work after being accelerated by the transmission box of the oil pump. The high-pressure oil pressurized by the double-connected high-pressure oil pump passes through the oil outlet pipe of the rear oil pump to the electromagnetic reversing valve, which controls the rotary hydraulic motor, swing oil cylinder and telescopic oil cylinder respectively to complete the adjustment of the angle and position of the cutter to realize the profiling function. Drive the hydraulic motor to the cutter to drive the blade to rotate to make cutting motion, and complete the cutting of new shoots of plants. By adjusting the angle and position of the cutter, the pruning operation of new shoots of different heights and different shapes of leaf curtains can be completed.

Positive effect, the tip trimmer of the present invention is installed on the tractor, can carry out walking operation, carry out shaping and pruning to the new fruit tree, keep tree shape, make it improve output and quality. It has the advantages of high mechanical operation efficiency, good pruning performance and labor saving. It is suitable for use as a machine for fruit tree pruning.
