Human assistance handheld type bar pawl variable diameter branch clamped electric grapefruit tree girdling peeler

Abstract

The present invention provides a hand-held electric pomelo tree girdling device with hand-held ratchets and pawls with variable diameters, including a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a ratchet, a pawl and a miniature DC motor, which are fixed on the handle. The spring is installed, the spring is a tension spring, the pawl and the ratchet are engaged to fix the moving circle on the branch of the pomelo tree, so as not to rotate with the girdling knife, the handle is divided into two parts, the fixed circle is installed on the handle, and the two fixed circles The parts are fastened together to form a complete circle, the handle opens and closes, and the fixed circle also opens and closes accordingly. There is a groove on the fixed circle, the roller is embedded in the groove and rolls in the groove, and the link runs through the roller The center hole of the center hole, the roller rotates in a circle, the connecting rod connects the two pomelo girders together, the girdling handle is fixed on the connecting rod, one end of the girdling handle is provided with a girdling knife, and the other end is provided with a connecting plate, Driven by the power, the girdling knife takes the fixed point of the handle and the connecting rod as the center of the circle, and takes the fixed point to the tip of the girdling knife as the radius to make a circular motion to girdling the pomelo tree.

Description

technical field [0001] The invention relates to an electric pomelo girdling device for manually assisting hand-held ratchet pawl variable-diameter branch clamping, which belongs to the field of mechanical technology. Background technique [0002] The pomelo tree needs to be girdled twice in one growing season. The first time should be in the middle and early May. It mainly inhibits the growth of spring shoots, forms moderate branches, lays the foundation for flower bud differentiation, and at the same time has the effect of preserving fruit for the first-hanging fruit trees. The second time is in early August, it can reduce the hair loss of autumn shoots and control late autumn shoots, and promote the physiological differentiation of flower buds. For flourishing trees with unbalanced vegetative growth and reproductive growth, hormone imbalance in the tree will lead to difficulties in flower bud differentiation and fruit stabilization. After peeling, the channel of the phloem...

Problems solved by technology

[0002] The pomelo tree needs to be girdled twice in one growing season. The first time should be in the middle and early May. It mainly inhibits the growth of spring shoots, forms moderate branches, lays the foundation for flower bud differentiation, and at the same time has the effect of preserving fruit for the first-hanging fruit trees. The second time is in early August, it can reduce the hair loss of autumn shoots and control late autumn shoots, and promote the physiological differentiation of flower buds. For flourishing trees with unbalanced vegetative growth and reproductive growth, hormone imbalance in the tree will lead to difficulties in flower bud differentiation and fruit stabilization. After peeling, the channel of the phloem screen tube is cut off, causing the transportation of carbohydrates to the root system to be blocked, inhibiting root growth and nutrient absorption, thereby playing a role in controlling water, and the accumulation of nutrients in the upper part of the girdling mouth improves the growth rate of the tree body. Cell liquid concentration and carbon-nitrogen ratio can promote flower bud differentiation and increase fruit setting rate. Because the growth angles of each side branch are 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 is large in size and easy to rotate The radius is large, and the inclination angle of the girdling knife is realized by the rotating oil cylinder telescopically driving the platform to rotate around the shaft. Only one surface can be rotated and tilted, and multiple surfaces can not be rotated and tilted at the same time. The scope of use has great limitations and is only suitable for For the girdling of the main trunk of the pomelo tree, in addition, the incision width of the girdling branches of the pomelo tree ranges from 1.0 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 woody fibers. When the knife is girdling at the girdling place, there is no clamping mechanism, which will tear the phloem adjacent to the girdling place, resulting in excessive girdling area, difficult healing of the girdling place of the pomelo tree, hindered nutrient delivery, and affecting the growth and development of the pomelo tree.
