[0024] As an implementation method, Figure 4As shown, the fallen fruit collection device 3 includes two groups of semicircular ring pieces 301, the fixed ends of the two groups of semicircular ring pieces 301 are hinged, and the movable ends are detachably connected by rotating studs 303, each group of ring pieces 301 includes two ring pieces 301 arranged upper and lower, and the upper and lower ring pieces 301 are connected by studs 303, and the studs 303 are rotatably connected to the ring pieces 301.
[0025] As an implementation mode, two groups of adjustment slots 502 are provided on the two adjustment slot plates 502, and each group of adjustment slots 502 includes three adjustment gears; the first end of the ring plate 301 is fixed in the adjustment gear by bolts, and the relative distance between the first ends of the two tree hugging plates 501 can be adjusted by adjusting the installation position of the tree hugging plate 501 in different adjustment gears.
[0026] As an embodiment, the locking mechanism 4 includes a latch 401 and a boss 402, a threaded hole is opened on the second end of one tree hugging piece 501, and a bar-shaped through hole 503 is opened on the second end of the other tree hugging piece 501, and three groups of bosses 402 are axially arranged on the latch 401, corresponding to the three adjustment positions of the adjustment slot 502, and the boss 402 can pass through the bar-shaped through hole when it is in a horizontal state, and one end of the latch 401 is detachably connected to the threaded hole, and the other end passes through the bar-shaped through hole together with the boss; by changing the fixing and insertion position of the latch 401, the relative distance between the second ends of the two tree hugging pieces 501 can be changed.
[0027] As an embodiment, the limiting mechanism 2 is symmetrically arranged on the left and right sides of the fallen fruit collection device 3, and each limiting mechanism 2 includes a pull rod and a fixed frame. The fixed frame is vertically installed on the frame 6, and the pull rod is horizontally arranged and passes through the through hole on the fixed frame.

At the same time, the telescopic rod of the fallen fruit collection mechanism is opened to open the umbrella surface and form a certain angle with the ground. Then the tree-shaking device is fixed to the frame so that the tree-shaking device applies a forward and backward shaking force to the trunk of the jujube tree. During the shaking process, the ripe fruits on the fruit tree fall and directly fall into the fallen fruit collection tarpaulin of the fallen fruit collection mechanism. The fruits collected by the fallen fruit collection tarpaulin can directly harvest the fruits in the fallen fruit collection mechanism. After the fruit picking is completed, the telescopic rod is shortened, the fallen fruit collection tarpaulin is closed, and the device is pushed to other fruit trees for fruit picking operations.
