Manually-assisted electric handheld spring plate variable-diameter waxberry branch clamping type girdling device

Abstract

The invention provides a manually-assisted electric handheld spring plate variable-diameter waxberry branch clamping type girdling device. The girdling device comprises a handle, a spring, a rotating shaft, spring plates, a setting circle and a miniature direct-current motor. The spring which is a tension spring is fixedly mounted on the handle, the spring plates clamp a waxberry branch in operation to avoid rotation along with a girdling knife, the setting circle is mounted on the handle which comprises two portions, two portions of the setting circle are closed to form a full circle, and the setting circle and the spring plates are open and closed along with opening and closing of the handle. The setting circle is provided with grooves, rollers are embedded into the grooves and roll in the grooves, and a link rod penetrates center holes of the rollers which are in circular rotation. Two girdling devices can be connected by the link rod, the girdling knife is arranged at one end of a girdling handle which is fixed to the link rod, and a link plate is arranged at the other end of the girdling handle. Under manual assistance, the girdling knife moves circularly to realize waxberry branch girdling by taking a fixed point of the handle and the link rod as a circle center and taking a distance from the fixed point to the tip of the girdling knife as a radius.

Description

technical field [0001] The invention relates to an electric bayberry girdling device for manually assisting a hand-held variable-diameter branch clamped by a spring plate, which belongs to the field of mechanical technology. Background technique [0002] Girdling of bayberry controls vegetative growth, coordinates the relationship between vegetative growth and reproductive growth, and promotes flower bud differentiation. Girdling hinders the downward transport of photosynthesis and accelerates the accumulation of nutrients, thereby increasing fruit yield. The growth of spring shoots and summer shoots prevents the root system of bayberry from being supplied with nutrients, inhibits vegetative growth, increases fruit setting rate, promotes fruit expansion, improves quality, improves fruit flavor, and matures earlier. 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 ...

[0002] Girdling of bayberry controls vegetative growth, coordinates the relationship between vegetative growth and reproductive growth, and promotes flower bud differentiation. Girdling hinders the downward transport of photosynthesis and accelerates the accumulation of nutrients, thereby increasing fruit yield. The growth of spring shoots and summer shoots prevents the root system of bayberry from being supplied with nutrients, inhibits vegetative growth, increases fruit setting rate, promotes fruit expansion, improves quality, improves fruit flavor, and matures earlier. 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 201410485285.2 uses a motor driven by a gasoline engine, which has a large volume and a large radius of gyration. The inclination angle of the girdling knife is driven by the rotating cylinder. Rotation around the rotation axis can only realize the rotation and tilt of one surface, and cannot realize the simultaneous rotation and tilt of multiple surfaces in space. The scope of use has great limitations, and it is only suitable for the trunk girdling of red bayberry. The incision width ranges from 0.2 to 5.0 cm, and the incision depth ranges from 0.2 to 0.5 cm. The incision should be even, and the phloem contains more wood fibers. The adjacent phloem is torn, resulting in too large girdling area, the girdling of red bayberry is not easy to heal, and nutrient transportation is blocked, which affects the growth and fruit setting rate of red bayberry
