Abstract

The invention provides a human-assisted handheld type electric longan girdling device using triangular blocks to clamp branches in a variable-diameter manner. The human-assisted handheld type electric longan girdling device comprises a handle, springs, a rotary shaft, the triangular clamp blocks, a fixed circle and a miniature direct-current motor, wherein one spring is fixedly mounted on the handle, the triangular clamping blocks are firmly fixed on longan branches by the acting force of the springs so as to prevent the girdling device from rotating along with a girdling cutter, the handle is divided into two parts, the fixed circle is mounted on the handle, two parts of the fixed circle are fastened to form a whole circle, the handle opens and closes to allow the fixed circle to open and close, the fixed circle is provided with a groove, rollers are embedded into the groove and roll in the same, a connecting rod penetrates the central holes of the rollers, the rollers rotate circumferentially, two longan girdling device bodies are connected through the connecting rods, a girdling handle is fixed on the connecting rod, one end of the girdling handle is provided with the girdling cutter, the other end of the girdling handle is provided with a connecting plate, and the girdling cutter circularly moves by using the fixing point of the handle and the connecting rod as the circle center and the distance from the fixing point to the tip of the girdling cutter as the radius so as to girdle longan under human assistance.

Description

technical field

[0001] The invention relates to a manually assisted hand-held electric longan girdling device for clamping branches with variable diameter triangular blocks, which belongs to the field of mechanical technology. Background technique

[0002] The basic principle of spiral girdling of longan branches and girdling to control winter shoots is to reduce the transport of photosynthetic products from the aboveground part of the plant to the roots, inhibit root growth, slow down vegetative growth and winter shoot extraction, and increase the accumulation of carbohydrates in shoots. Provide more sufficient nutrients for the flower bud differentiation and flowering of the fruiting mother branch. Longan has obvious small and large years, and even empty every year. By adopting girdling technology, it can overcome the large and small years. Longan has obvious small and small years, even every year. If there is no fruit, the girdling technology can overcome the large and sm...

Embodiment 1

[0021] in such as Figure 1~3In the shown embodiment, a kind of hand-held electric longan girdling device with reduced-diameter branch clamping of triangular blocks with artificial assistance includes handle 1, spring 2, rotating shaft 3, triangular clamping block 5, fixed circle 4 and micro DC motor. 12. Fixedly install spring 2 on handle 1, spring 2 is a tension spring, handle 1 is divided into two parts, fixed circle 4 is installed on handle 1, fixed circle 4 is divided into two parts, and the two parts of fixed circle 4 are fastened together Together they form a full circle, the handle 1 opens and closes, and the fixed circle 4 also opens and closes accordingly. There is a groove on the fixed circle 4, and the roller 7 is embedded in the groove and rolls in the groove to make a circular motion , the connecting rod runs through the central hole of the roller 7, two longan girdling devices are connected together, the girdling handle 6 is fixed on the connecting rod, the conn...
