It is a new type of vine branch crushing machine developed based on the characteristics of similar machines at home and abroad. It has a unique structure, simple applicability, and advanced performance. It has the characteristics of high component strength, safety and reliability, high crushing efficiency, uniform scattering, low vibration noise, high standardization coefficient, and easy maintenance and use. The main application scope of this machine is to mechanically and directly return the branches of fruit trees pruned in orchards to the field. The use of this machine can effectively solve the contradiction of labor shortage and delayed farming during the harvest period, and can avoid environmental pollution caused by disorderly stacking and placement on the edge of the technical ditch. The 4TFH-150 (165) series vine branch crushing and returning machine adopts a three-point hydraulic sliding suspension, universal joint transmission power, intermediate gear transmission, and side triangle belt transmission structure. It is a work tool designed for tractors with 50-120 horsepower. The machine is mainly composed of universal joint drive shaft, frame, intermediate gearbox, V-belt drive system, blade shaft, ground wheel, hydraulic sliding suspension lifting mechanism, branch picking hook and other components.
