Artificial assisting handheld spine and pawl reducing branch clamping bergamot pear girdling device

Abstract

The invention provides an artificial assisting handheld spine and pawl reducing branch clamping bergamot pear girdling device which comprises a handle, a spring, a rotary shaft, a dynamic circle, a fixed circle, a spine and a pawl. The spring is fixedly mounted on the handle, the spring is a tension spring, and during work, the pawl and the spine are engaged to fix the dynamic circle to a branch of bergamot pears to prevent the dynamic circle from rotating along with a girdling cutter. The handle is divided into two parts, the fixed circle is mounted on the handle, and two parts of the fixed circle are buckled together to form a complete circle. The handle is opened and closed, the fixed circle is opened and closed accordingly, a groove is formed in the fixed circle, a roller is embedded into the groove and rolls in the groove, a linkage rod penetrates through a center hole of the roller, and the roller does circular motion. Two bergamot pear girdling devices are connected together through the linkage rod, a girdling handle is fixed to the linkage rod, the girdling cutter is arranged at one end of the girdling handle, and a linkage plate is arranged at the other end of the girdling handle. Under artificial assistance, the girdling cutter does circular motion with a handle and the linkage rod fixed point as the circle center and with a cutter point from the fixed point to the girdling cutter as the radius to girdle the bergamot pears.

Description

technical field [0001] The invention relates to a manually assisted hand-held ratchet ratchet ratchet variable-diameter branch clamping pear girdler, which belongs to the field of mechanical technology. Background technique [0002] Fragrant pear saplings grow vigorously, especially when the dominance of the top is strong and it is difficult to form flowers. In order to achieve the purpose of early fruiting and early high yield, the measures of girdling can solve the problems of strong top and weak bottom, poor flower formation, and low fruit setting rate. The 40-50-year-old tree has the problems of being strong at the top and weak at the bottom, bare inside, and the fruiting part moves outward, resulting in a decrease in fruit quality and yield per unit area. The side branches are girdled at intervals, and the growth angle of each side branch is not only the same. , the distance between the side branches is small, and the radius of gyration is small. Invention patent 201410...

AI Technical Summary

Problems solved by technology

[0002] Fragrant pear saplings grow vigorously, especially when the dominance of the top is strong and it is difficult to form flowers. In order to achieve the purpose of early fruiting and early high yield, the measures of girdling can solve the problems of strong top and weak bottom, poor flower formation, and low fruit setting rate. The 40-50-year-old tree has the problems of being strong at the top and weak at the bottom, bare inside, and the fruiting part moves outward, resulting in a decrease in fruit quality and yield per unit area. The side branches are girdled at intervals, and the growth angle of each side branch is not only the same. , the distance between side branches is small, and the radius of gyration is small. Invention patent 201410485285.2 uses a motor driven by a gasoline engine, which has a large volume and a large radius of gyration. The surface is rotated and tilted, and the simultaneous rotation and tilt of multiple surfaces in space cannot be realized. The scope of use has great limitations. It is only suitable for the trunk girdling of fragrant pears. In addition, the incision width of the girdling branches of fragrant pears ranges from 1.0 to 3.0 cm, the incision depth ranges from 0.2 to 0.8 cm, the incision should be even, and the phloem contains more wood fibers. As a result, the girdling area is too large, the girdling of fragrant pears is not easy to heal, and the nutrient delivery is blocked, which affects the growth and fruit setting rate of fragrant pears
