The spacing can be controlled by the clamping push rod 183 to adapt to clamping tree trunks of different sizes.

At least three folding and unfolding units 200 are arranged along the circumferential direction of the tree-holding clamping mechanism 100. The folding and unfolding units 200 include: a parallel six-bar crank slider mechanism and a four-bar folding and unfolding umbrella rib mechanism, wherein:

The parallel six-bar crank slider mechanism includes a first connecting rod 210, a second connecting rod 220, a third connecting rod 240, a fifth connecting rod 250, and a sixth connecting rod 260. The first connecting rod 210 and the third connecting rod 240 are arranged in parallel, the fifth link 250 and the sixth link 260 are arranged in parallel, one end of the first link 210 is pivotally connected to the bottom ring 150, and the other end is pivotally connected to one end of the second link 220.

One end of the third link 240 is pivotally connected to the top ring. , the other end is pivotally connected to the upper end of the second link 220, the middle part of the third link 240 is hinged to one end of the fifth link 250, and the other end of the fifth link 250 is pivotally connected to the lifting ring;

The four-bar mechanism for folding and unfolding the ribs includes a fourth link 230, a seventh link 270, and a folding arm 280. One end of the fourth link 230 is pivotally connected to the top ring, and the other end is connected to the seventh link. One end of the seventh link 270 is pivotally connected, the middle part of the seventh link 270 is pivotally connected to the other end of the second link 220, and the other end of the seventh link 270 is fixedly connected to one end of the folding arm 280; when folded When the expansion unit 200 is in the unfolded state, the angle between the straight line and the horizontal direction of the fourth link 230 , the seventh link 270 and the folding arm 280 determines the umbrella-shaped arc surface of the inverted umbrella. Analyzing the motion characteristics of the four-bar mechanism for folding and unfolding umbrella ribs, it can be concluded that the angle between the inverted umbrella rib and the horizontal plane after unfolding depends on the size of each member of the four-bar mechanism for folding and unfolding umbrella ribs. Since the third link 240 and the fourth link The lengths of the second link 230 and the seventh link 270 need to meet the key constraint of being collinear after expansion. Therefore, the expansion of different umbrella-shaped arc surfaces can be achieved by modifying the length of the second link 220.

The folding and unfolding arm 280 includes a folding and unfolding groove 281 and a folding and unfolding rod 282 that are hinged to each other through a hinge shaft. The hinge shaft is arranged in the folding groove. After unfolding, the folding and unfolding groove 281 can block the folding and unfolding rod 282 so that the folding and unfolding rod 282 can be unfolded. Finally, it remains parallel to the folding arm 280 to expand the collection area. The folding rod can be fixed during the unfolding process, so that the folding and unfolding rod 282 has a certain angle and height, which can effectively block falling fruits and improve the collection rate.

The motor 113 drives the screw rod 111 to rotate, causing the lifting ring to move up and down, thereby driving the fifth connecting rod 250 to move, thereby realizing the folding and unfolding unit 200.

As shown in Figure 10, the canvas 300 is adapted to the folding arm of the four-bar mechanism of the umbrella rib. The overall shape is a polygon (octagon in this example). Each intersection of the polygon and the folding arm are unfolded. In addition, the center of the canvas should be equipped with a through hole 300-2 that is suitable for the tree trunk. Select the center of the through hole 300-2 to an end point of the polygon to perform slit 300-1 to divide the canvas into two parts.

As shown in Figures 7 and 8, the entire movement process includes expansion and contraction. The details are as follows:

(1) Deployment: The lift ring rises to drive the outer end of the fifth link 250 to rise, thereby driving the second link 220 to rise and lift the folding arm 280. The first link 210 and the third link 240 move in the same way. The movement of the rod 250 and the sixth link 260 is always parallel, so that the folding arm 280 and the fourth link 230 are in the dead center position after being collinear. At this time, the folding arm 282 can be unfolded, the mechanism is in the fully unfolded state, and the link structure is The parallel six-bar structure has a large load-bearing capacity.

(2) Folding: The lifting ring drops to drive the outer end of the fifth link 250 to drop, thereby driving the second link 220 to drop, and the folding arm 280 tilts downward. The first link 210 and the third link 240 move in the same way. The movement of the fifth link 250 and the sixth link 260 is always parallel. When the lifting ring is in the lowest position, the folding rod is retracted into the folding groove, and the folding and unfolding unit 200 is in a fully folded state, occupying less space.

The invention has strong stability and reliability, and specifically has the following advantages:

1) Compared with the general inverted umbrella type, the structure is more stable and has a stronger load-bearing load through the drive expansion of the parallel six-rod crank slider mechanism.

2) By modifying the length of the second rod 220, the collection of umbrella-shaped arc surfaces at different angles can be achieved, which has strong tree adaptability.

3) The collection device has a relatively large folding and unfolding capacity and can achieve minimal folding.

4) The folding arm 280 design for collecting umbrella ribs expands the collecting area of the umbrella surface.

This design is based on the parallel six-rod crank slider mechanism, innovating the structure of the inverted umbrella-type folding and unfolding unit 200. The parallel six-rod mechanism has a stable structure. The motor 113 drives the expansion and closing of the four-rod mechanism for folding the umbrella ribs, so that after unfolding The inverted umbrella type collection device has strong stability and load-bearing capacity. After the four-bar mechanism of the folding and unfolding umbrella rib is deployed, the fourth link 230, the seventh link 270 and the folding and unfolding arm 280 are collinear to form an inverted umbrella-shaped rib unit. At this time, the quadrilateral shape of the four-bar mechanism becomes a triangle. The purpose of this design is to break the problem of traditional inverted umbrellas taking up a lot of space when the ribs are not folded. The four-rod mechanism for folding and unfolding the ribs is designed to fold the ribs when the inverted umbrella collection device is folded, reducing the space occupied. With the canvas 300 It can realize the harvesting of forest fruits in a large area. Since the parallel six-rod mechanism and the four-rod folding and unfolding umbrella rib mechanism are designed using the folding and unfolding principle, the collection device takes up less space after being folded and has high collection efficiency. Compared with manual harvesting methods, it not only reduces the labor cost of picking and collecting cost, and greatly saves operating time and reduces labor costs; in addition, the outer umbrella frame of the present invention is provided with a folding arm 280, which can be deployed twice by unfolding the folding arm 280, thereby obtaining a larger collection range and improving the collection efficiency.
