[0002] With the development of technology, fruit picking has evolved from the early manual picking on trees to the use of picking tools, which has greatly improved the picking efficiency and reduced the picking difficulty.

[0003] However, currently, the common fruit picking devices on the market are all for single fruit picking, which are completed by grasping with mechanical claws or cutting the fruit stalk with a knife. However, for example, for persimmon trees, the branch-breaking method is usually used for persimmon picking. And a Chinese utility model patent with the publication number CN213960824U provides a persimmon picking device, which includes a scissor sleeve arranged at the top of a telescopic picking rod, and the electric blade in the scissor sleeve cuts off the branches and leaves to realize the picking of a single persimmon. After the picking is completed, the branches of the persimmon tree still need to be trimmed, and the persimmons cannot be picked according to the branch-breaking method, which cannot meet the actual picking needs. Summary of the Utility Model

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] When picking fruits by the branch-breaking method, it is necessary to break the branch connected to the fruit. For example, according to the existing public literature, such as the literature: Guan Junjie. Branch-breaking Picking Method for Persimmon Fruits [J]. Hebei Fruits, 1998, (03): 45. It is mentioned that the advantages of branch-breaking harvesting are: first, changing the aerial operation to ground operation, reducing the labor consumption and reducing the damage of persimmon fruits. Second, after the fruiting branches are broken off, the branch groups can be updated in time to prevent the fruiting position from shifting outward; and the amount of winter pruning is reduced during winter pruning. Third, the pests overwintering under the persimmon calyx can be removed together. When picking fruits by the branch-breaking method, the methods disclosed in the prior art can be referred to, such as the objects suitable for picking by the branch-breaking method disclosed in the literature: Zhang Shurong. Scientific Picking of Persimmons [J]. Rural Economy and Technology, 1999, (10): 44.

[0020] Example 1

[0021] Reference Figure 1 With Figure 2 , this embodiment provides a fruit picking device, including a picking rod 10, a clamping drive 20, a clamping member 30 and a clamping sleeve 40. The top of the picking rod 10 is connected to the clamping member 30. The clamping member 30 is sleeved outside the clamping sleeve 40, so that a limiting space is formed between the top of the clamping sleeve 40 and the clamping member 30. The clamping sleeve 40 is connected to the picking rod 10 through the clamping drive 20. The clamping drive 20 is used to drive the clamping sleeve 40 to move up and down in the clamping member 30, so as to realize the adjustment of the size of the limiting space.

[0022] During use, the branch 80 with fruits is extended into the limiting space. At the same time, the clamping drive 20 is used to narrow the limiting space, so that the clamping sleeve 40 and the clamping member 30 stably clamp the branch 80. Then, the branch 80 is broken by rotating the picking rod 10 or the picking rod 10 is pulled down to break the branch 80. Finally, the clamping drive 20 is used to expand the limiting space to separate the branch with fruits, which is convenient for collecting the picked fruits.

[0023] For example, the clamping member 30 can be selected as an arc-shaped plate. One end of the arc-shaped plate is connected to one end of the top of the picking rod 10. The other end of the arc-shaped plate is flipped to the other end of the top of the picking rod 10 and clamped or kept covering the top end of the picking rod 10 through telescopic restraint, which is convenient for cooperating with the clamping sleeve 40 below to limit the branch 80 in the limiting space.

[0024] Further explanation, the picking rod 10 can be selected as materials such as plastic or light alloy. The picking rod 10 and the clamping member 30 can be selected as an integral structure or a detachable connection method. Taking the two as an integral structure as an example for explanation.

[0025] Specifically, a picking chute 50 is opened on the clamping member 30. The picking chute 50 is located on the opposite sides of the clamping member 30, so that the branch 80 can extend from one side of the circumference of the clamping member 30 to the opposite side of the circumference of the clamping member 30. The top of the clamping sleeve 40 jacks up the branch 80 at the middle position of the clamping member 30, so as to realize the clamping limit of the branch 80.

[0026] Among them, the inlet end of the picking chute 50 communicates with the outside of the clamping member 30. The limiting end of the picking chute 50 bends upward to one side of the inlet end of the picking chute 50, so that the picking chute 50 allows the branch 80 to extend from its inlet end and slide to its limiting end. The gap between the inner wall of the limiting end of the picking chute 50 and the top of the clamping sleeve 40 is the limiting space. By jacking up the bottom of the branch 80 through the clamping sleeve 40, the top of the branch 80 contacts the inner wall of the limiting end of the picking chute 50, thereby realizing the stable clamping and limiting of the branch 80.

[0027] For example, the picking chute 50 is of a V-shaped structure, a U-shaped structure, an L-shaped structure or an arc-shaped structure.

[0028] When the picking chute 50 is of an L-shaped structure, the inlet end of the picking chute 50 is horizontally arranged on the right side of the clamping member 30, and the limiting end of the picking chute 50 extends upward below the top surface of the clamping member 30. During use, the branch 80 can be inserted into the picking chute 50 from its inlet end, and then the picking rod 10 is moved horizontally so that the branch 80 is located at the corner of the picking chute 50. Then the picking rod 10 is moved downward so that the branch 80 contacts the inner wall of the limiting end of the picking chute 50. At the same time, the top of the clamping sleeve 40 jacks up the part of the branch passing through the clamping member 30, thereby realizing the clamping of the branch 80.

[0029] When the picking chute 50 is of a V-shaped structure or a U-shaped structure, the picking chute 50 includes a first vertical chute 51, an inclined chute 52 and a second vertical chute 53 connected in sequence. The top of the first vertical chute 51 communicates with the top end of the clamping member 30. The bottom of the first vertical chute 51 is above the bottom of the second vertical chute 53. The limiting space is between the inner wall of the top of the second vertical chute 53 and the top of the clamping sleeve 40. The top end of the first vertical chute 51 is the inlet end of the picking chute 50, and the top of the second vertical chute 53 is the limiting end of the picking chute 50.

[0030] During actual use, the picking rod 10 drives the clamping member 30 to move upward, so that the branch 80 slides downward from the top of the first vertical chute 51, passes through the inclined chute 52 and then slides to the bottom of the second vertical chute 53. Then the picking rod 10 is moved downward to move the branch 80 to the top of the second vertical chute 53, and the clamping sleeve 40 tightens the branch 80 at the top of the second vertical chute 53 to realize clamping and limiting, which is convenient for subsequent branch folding and picking.

[0031] To facilitate the insertion of the branch 80 into the top of the first vertical chute 51, the top of the clamping member 30 is preferably inclined. The lower end surface of the top of the clamping member 30 is in contact with the top of the first vertical chute 51. Thus, during the actual picking process, it is not necessary to adjust the picking rod 10 to align the branch 80 with the top of the first vertical chute 51. Instead, the branch 80 is brought into contact with the top of the clamping member 30 and then the picking rod 10 is moved upward, enabling the branch 80 to slide into the first vertical chute 51, thereby improving the picking efficiency.

[0032] Further elaboration, the clamping drive 20 is arranged below the clamping sleeve 40. Correspondingly, an activity chamber 60 is provided inside the picking rod 10 above. The activity chamber 60 is preferably coaxially arranged with the picking rod 10. The clamping drive 20 is arranged inside the activity chamber 60, and the clamping sleeve 40 is also located inside the activity chamber 60.

[0033] The clamping drive 20 can be selected as a telescopic drive mechanism. By controlling the lifting of the telescopic drive mechanism, the size of the limiting space between the clamping sleeve 40 and the clamping member 30 can be adjusted, facilitating the adjustment and control of the size of the limiting space.

[0034] To reduce the picking intensity and the overall weight, the clamping drive 20 is preferably a compression spring. At this time, the bottom end of the compression spring is connected to the bottom end of the activity chamber 60, and the top end of the compression spring is connected to the bottom end of the clamping sleeve 40.

[0035] Taking the clamping drive 20 being a compression spring as an example for explanation, when picking fruits, the clamping sleeve 40 moves upward under the action of the clamping drive 20. It can be selected that the top of the clamping sleeve 40 is flush with the top of the second vertical chute 53. Subsequently, when the picking rod 10 moves upward, the branch 80 pushes the clamping sleeve 40 downward, and the compression spring is compressed. When the branch 80 slides to the top of the second vertical chute 53, the clamping sleeve 40 pushes the branch 80 upward under the action of the compression spring, enabling the top of the second vertical chute 53 and the top of the clamping sleeve 40 to perform clamping and limiting on the branch 80, facilitating the realization of branch-breaking picking.

[0036] Further elaboration, to facilitate the release of the clamped branch 80, a push plate 70 is selected to be arranged at the top of the clamping sleeve 40. The top end of the push plate 70 is vertically arranged and extends to the outside of the upper end of the clamping member 30. When releasing the clamped branch 80, the push plate 70 can be abutted against a tree stump or other fixed objects close to the ground, and the clamping sleeve 40 is pushed to move through the push plate 70, thereby completing the collection of fruits and the picking of fruits.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
