[0026] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below. The technical features in various embodiments of the present utility model can be combined correspondingly without conflict.

[0027] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0028] As Figure 1 shown, as a preference for the specific embodiment of the present utility model, this embodiment provides a multi - angle hierarchical citrus picking device, including a scissor head, a first bevel gear 6, a second bevel gear 7, a telescopic rod, a steel wire rope, a braking handle 13 and a fruit receiving and guiding device 18.

[0029] As Figure 2 shown, in the device provided by the present utility model, the scissor head includes a fixed blade 1, a rotating blade 2 and an elastic member 12. One ends of the fixed blade 1 and the rotating blade 2 are hinged through a rotating shaft 3. A long - hole groove for limiting the opening and closing angle between the fixed blade 1 and the rotating blade 2 is also formed on the fixed blade 1, and the long - hole groove has a certain radian. A sliding member 4 passes through the long - hole groove on the fixed blade 1 to connect the other end of the rotating blade 2 with the fixed blade 1. In this embodiment, the rotating shaft 3 is a screw, and the sliding member 4 is a pin.

[0030] In the device provided by the present utility model, one end of the elastic member 12 is fixedly connected with the sliding member 4, and the other end is connected with one end of the steel wire rope. By pulling the steel wire rope, the elastic member 12 is controlled to expand and contract. The sliding member 4 slides in the long - hole groove on the fixed blade 1 through the expansion and contraction of the elastic member 12, driving the rotating blade 2 to open and close. The fixed blade 1 and the rotating blade 2 cooperate to shear the citrus stalk. In order to prevent the citrus stalk from slipping during the shearing process, a limiting member 5 for clamping the citrus stalk is further provided at the top of the fixed blade 1 in this embodiment. In addition, holes for reducing friction are also formed on the fixed blade 1 and the rotating blade 2.

[0031] As Figure 2As shown in the figure, the bottom of the fixed blade 1 is rigidly connected to the first bevel gear 6. The second bevel gear 7 is perpendicular to the first bevel gear 6, and the gears on the first bevel gear 6 and the second bevel gear 7 are meshed. The fixed shaft 8 passes through the through hole in the middle of the first bevel gear 6, and a rotational connection is formed between the first bevel gear 6 and the fixed shaft 8. Support rods 10 are arranged at both ends of the fixed shaft 8 by means of bolt connection, and the scissor head is fixed on the support 11 through the support rods 10. In this embodiment, the support 11 is made of an L-shaped steel plate, which is divided into a vertical part and a planar part. The bottom of the support rod 10 is fixed on the planar part of the support 11.

[0032] In the device provided by the present utility model, the bottom of the second bevel gear 7 is key-connected to the motor 9, and the motor 9 can drive the second bevel gear 7 to rotate. Through the meshing of the second bevel gear 7 and the first bevel gear 6, the first bevel gear 6 rotates on the fixed shaft 8. When the motor 9 drives the second bevel gear 7 to rotate clockwise, the first bevel gear 6 rotates counterclockwise to drive the scissor head to rotate, so that the angle between the scissor head and the lower telescopic rod becomes larger. When the motor 9 drives the second bevel gear 7 to rotate counterclockwise, the first bevel gear 6 rotates clockwise to drive the scissor head to rotate, so that the angle between the scissor head and the lower telescopic rod becomes smaller. By adjusting the angle of the scissor head, citrus fruits at different angles can be picked more flexibly.

[0033] In the device provided by the present utility model, the telescopic rod includes a fixed block 14, an upper section sleeve 141 and a lower section sleeve 142 with a hollow interior. The fixed block 14 is fixed at the top of the lower section sleeve 142, and the upper section sleeve 141 passes through the fixed block 14 and is inserted into the lower section sleeve 142. A number of holes matching the size of the fixed pins are longitudinally spaced on the upper section sleeve 141. The scissor head is fixed on the top of the upper section sleeve 141 through the vertical part of the support 11.

[0034] In this embodiment, a limit elastic piece 15 is further provided on the fixed block 14, and a fixed pin matching the holes opened on the upper section sleeve 141 is provided on the limit elastic piece 15. Loosen the limit elastic piece 15, adjust the length of the upper section sleeve 141 inserted into the lower section sleeve 142, and then press down the limit elastic piece 15 so that the fixed pin on the limit elastic piece 15 passes through the corresponding hole on the upper section sleeve 141 to complete the adjustment of the total length of the telescopic rod.

[0035] In the device provided by the present utility model, one end of the steel wire rope is connected to the elastic member 12, and the other end passes through the telescopic rod and is connected to the brake handle 13 at the bottom of the lower section sleeve 142. The brake handle 13 controls the tension of the steel wire rope. In order to facilitate the control of the retraction and extension of the steel wire rope, a winding wheel 16 is provided on one side of the lower section sleeve 142 of the telescopic rod close to the brake handle 13 in this embodiment. A battery pack 17 for supplying power to the motor 9 is also provided on the telescopic rod.

[0036] In this embodiment, the brake handle 13 is designed as a positive lever, and a relatively small force can be used to pull the rotary blade 2 to achieve the shearing motion. Since a spring member 12 is provided between the fixed blade 1 and the rotary blade 2, the rotary blade 2 can be reset after the brake handle 13 is released.

[0037] Since the length of the telescopic rod in the device provided by the present utility model can be adjusted to pick citrus fruits at high places. However, in order to avoid damage caused by the direct dropping of the citrus fruits picked at high places, in this embodiment, a fruit receiving and guiding device 18 is provided at the top of the upper joint sleeve 141 of the telescopic rod. The fruit receiving and guiding device 18 can be a net bag. The fruit receiving and guiding device 18 first receives the picked citrus fruits, and then through the guiding action of this device, the citrus fruits are collected into the collection basket carried by the picker.

[0038] When using the multi-angle grading citrus picking device provided in this embodiment for picking, first adjust the length of the telescopic rod according to the height of the fruit, then adjust the angle of the scissor head according to the orientation of the fruit, then rotate the wire winding wheel to tighten the steel wire rope, then hold the brake handle tightly, rely on the force transmitted by the steel wire rope to control the closing of the scissor head to cut the fruit, release the brake handle, and the scissor head opens by elastic force, and the fruit falls into the net bag.

[0039] The above embodiments are only a preferred solution of the present utility model, but it is not intended to limit the present utility model. Those of ordinary skill in the relevant technical fields can still make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all technical solutions obtained by adopting the equivalent replacement or equivalent transformation method fall within the protection scope of the present utility model.
