Artificial assistance handheld spring plate variable-diameter branch clamping electric orange tree girdling device

Abstract

The invention provides an artificial assistance handheld spring plate variable-diameter branch clamping electric orange tree girdling device. The girdling device comprises a handle, a spring, a rotary shaft, a spring plate, a fixed ring and a miniature DC motor. The spring is fixedly mounted on the handle. A tension spring is used as the spring. During operating, the spring plate is clamped onto an orange tree branch to be prevented from rotating along with a girdling knife. The handle is divided into two parts. The fixed ring is mounted on the handle. Two parts of the fixed ring are buckled together to form a full circle. When the handle is opened and closed, the fixed ring and the spring plate are also opened and closed accordingly. The fixed ring is provided with grooves. Rolling wheels are embedded into the grooves and roll in the grooves. A link rod penetrates through center holes of the rolling wheels. The rolling wheels rotate circumferentially. The link rod connects two orange tree girdling devices together. A girdling handle is fixed to the link rod. One end of the girdling handle is provided with the girdling knife. The other end of the girdling handle is provided with a yoke plate. Under artificial assistance, the girdling knife does circular movement to conduct girdling on an orange tree with the fixed point of the handle and the link rod as the circle center and with the distance from the fixed point to the knife point of the girdling knife as the radius.

Description

technical field [0001] The invention relates to a hand-held electric citrus girdling device for clamping branches with variable diameters by a spring plate, which belongs to the field of mechanical technology. Background technique [0002] Citrus girdling can replace the hormone to protect the fruit, prevent the fruit from being rough, thicken the peel, and weaken the flavor caused by the hormone. It can save the cost of shoot control and overcome the clustering of autumn shoots caused by repeated wiping of summer shoots , the number of weak branches increases, and the quality of the mother branches of autumn shoots decreases, resulting in a vicious cycle of many or no results. Citrus girdling inhibits the growth of spring and summer shoots, and girdling hinders the downward transport of photosynthesis, making citrus The root system of oranges cannot get the supply of nutrients, which inhibits vegetative growth, promotes flower bud differentiation, increases fruit setting ra...

[0002] Citrus girdling can replace the hormone to protect the fruit, prevent the fruit from being rough, thicken the peel, and weaken the flavor caused by the hormone. It can save the cost of shoot control and overcome the clustering of autumn shoots caused by repeated wiping of summer shoots , the number of weak branches increases, and the quality of the mother branches of autumn shoots decreases, resulting in a vicious cycle of many or no results. Citrus girdling inhibits the growth of spring and summer shoots, and girdling hinders the downward transport of photosynthesis, making citrus The root system of oranges cannot get the supply of nutrients, which inhibits vegetative growth, promotes flower bud differentiation, increases fruit setting rate, promotes fruit expansion, and improves quality. The growth angle 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. Only one surface can be rotated and tilted, and multiple surfaces in space cannot be rotated and tilted at the same time. The scope of use is very limited, and it is only suitable for the girdling of citrus trunks. In addition, the range of incision width for girdling branches of citrus The incision depth ranges from 0.5 to 3.0 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 phloem is torn, resulting in too large girdling area, the girdling of citrus is not easy to heal, and nutrient transport is blocked, which affects the growth and fruit setting rate of citrus
