Artificial assistance handheld bar and pawl variable-diameter branch clamping orange tree girdling device

Abstract

The invention provides an artificial assistance handheld bar and pawl variable-diameter branch clamping orange tree girdling device. The girdling device comprises a handle, a spring, a rotary shaft, a moving ring, a fixed ring, a ratchet bar and a ratchet pawl. A tension spring is used as the spring. During operating, the ratchet pawl is engaged with ratchets to fix the moving ring to an orange tree branch to prevent the moving ring 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. The handle is opened and closed, and the fixed ring is 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 manually assisted hand-held ratchet girdling device with variable diameter branches for holding citrus fruits, belonging 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. For girdling, the growth angle of each side branch is not only the same, the dist
