TECHNICAL FIELD

[0001] The utility model relates to the technical field of forestry machines, in particular to a transmission mechanism of a fruit tree girdling machine and the fruit tree girdling machine. BACKGROUND

[0002] Girdling (also known as girdling) is a technique of cutting the branches and trunks in a ring shape during the growth period of fruit trees. By peeling the bark between the two cutting edges and exposing the wood, girdling can temporarily hinder the downward transport of organic matter, reduce the nutrient supply of the root system, promote the accumulation of nutrients above the peeled edge, effectively inhibit the vegetative growth, promote the differentiation of flower buds, and significantly improve the fruit quality. The existing electric girdling equipment has the following problems in actual application: due to the inconsistency of the hardness and surface flatness of the bark at different positions (such as the greater and harder concave-convex degree of the tree knot part), the actual cutting force during girdling is often unstable, the equipment is easy to vibrate and deviate, resulting in excessive cutting depth of the cutter, motor stall, or insufficient cutting depth, and the bark cannot be completely peeled. The above problems not only significantly reduce the work efficiency of girdling operation, but also may cause unnecessary damage to the fruit trees, limiting the promotion and application of electric girdling technology. Therefore, it is necessary to design an electric girdling equipment that is stable in work and easy to operate, and improve the overall effect of girdling operation. SUMMARY
