Description

Technical Field

[0001] The utility model relates to the technical field of fruit pruning, in particular to a fruit pruning auxiliary device. Background Art

[0002] Sunshine Rose grapes are a plant of the genus Vitis in the family Vitaceae. They have a well-developed root system; the young shoots are green and hairless, the leaves of the young shoots are mostly light white with hairs, and the new shoots turn yellow-brown when they mature; the leaves are large, fan-shaped and medium-thick; the flowers are bisexual, the flesh is soft, and has a strong rose fragrance; the buds sprout in early March, the flowers bloom in early May, and the fruits begin to mature in mid-August. Sunshine Rose grapes are named Sunshine Rose because of their high sugar content, crisp and juicy flesh, excellent fresh food quality, and rose fragrance.

[0003] When the Sunshine Rose grape grows, its branches and leaves need to be pruned. Appropriate pruning can control the growth potential of the grape plants and avoid excessive growth that causes nutrient dispersion and reduced fruit quality. Reasonable pruning can make the grape plants concentrate their energy on a few main branches and clusters, thereby increasing the sugar content and taste of the fruit. However, the existing pruning method is that the staff manually prunes the grape racks with pruning shears, which is inefficient. The grape racks are generally taller than human height and require lifts or ladders, which increases the danger of the staff. The pruned grape branches and leaves are scattered on the ground, affecting the environment. Therefore, those skilled in the art provide a fruit pruning auxiliary device to solve the problems raised in the above background technology. Utility Model Content

By adjusting the second transmission rod and the two-way screw rod, the pruning box and the pruning knife can be accurately adjusted at various angles, which can adapt to grape plants of different types and growth states, thereby improving adaptability and application range; Because a collection box is provided, some acidic substances may be released during the decomposition of grape branches and leaves, affecting the pH value of the soil, and grape branches and leaves usually contain more cellulose and lignin, which decompose slowly in the soil. Therefore, they will not immediately release nutrients for plants to use, but will take a certain amount of time to decompose into a form that can be absorbed by plants, so that they can be collected by the collection box, thereby improving soil protection.
