The invention has the following technical effects:

the invention is different from the existing vibrating harvester and the existing impact harvester. The existing harvester only has single vibration or single beating, the force is too small, fruits are not easy to fall off, the force is too large, and branches are easy to damage.

The invention adopts a novel picking mode combining oblique vibration and disturbance type beating, so that the oblique acting force of the oblique vibration and the beating force of the disturbance type beating form force synthesis, the vector of the synthesized force is constantly changed, not only the magnitude of the resultant force is changed, but also the direction of the resultant force is constantly changed, thus multi-direction and multi-force hitting on fruit grains on different branches and different positions is realized, even if the fruit grains on the same position are more easily dropped under the double actions of the oblique vibration force and the disturbance type beating force, the picking speed is higher, the efficiency is higher, and the problems that the existing harvester cannot pick the fruit grains in multiple directions, the fruit grains are not easy to drop, the picking speed is slow, and the beating missing rate is high are solved.

The elastic rod with the special design has good elasticity and toughness, and can improve the disturbing type flapping effect. According to the tree picking device, the uniformly-arranged positioning holes are formed in the first rotary table, the corresponding pin shaft holes are formed in the lower portion of the elastic rod, the mounting angle of the elastic rod can be adjusted through the positioning pins according to the actual situation of trees, the main rod mounted on the elastic rod is composed of the inner rod and the outer rod, the outer rod can slide along the inner rod to adjust the length, the tree picking device has better adaptability to trees, and the picking effect can be further improved.

In addition, the fruit sweeping and receiving devices are arranged on two sides of the carriage, when the third rotary table rotates, the fixed pin and the shifting fork are driven to rotate, so that the connecting handle is intermittently shifted, the connecting handle drives the strip-shaped broom, the support and the roller to do arc motion around the rotating shaft, and the strip-shaped broom sweeps fruits falling on the inclined plate into the fruit receiving grooves on the front side and the rear side of the inclined plate and falls into the fruit receiving box through the discharge hole.

The fruit picking device is novel in structure and ingenious in design, can greatly improve the fruit picking speed, reduces tree damage, realizes multi-direction and multi-force hitting on fruits on different branches and at different positions, is low in fruit leakage rate and high in fruit falling speed, saves manpower and material resources, reduces cost and improves fruit harvesting efficiency.
