DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Example 1: Please refer to Figure 1-Figure 9The present invention provides a technical solution: an electric power-assisted hand-push picking device for pomegranate picking, which is used for picking pomegranates and includes a carrier body 1 and a first handle 2 for controlling the movement of the carrier body 1. The carrier body 1 is provided with a telescopic picking rod 3 for assisting in picking pomegranates of different heights, which can easily adjust the picking height to adapt to pomegranates of different heights, thereby improving the picking efficiency and flexibility. The carrier body 1 is also provided with a rotating component 4 and an angle adjustment component 5 for adjusting the overall angle and direction of the telescopic picking rod 3. The top of the telescopic picking rod 3 is also provided with an adjustment pruning component 6 for pulling and cutting off distant pomegranate branches. The ability to adjust the direction and angle of the picking rod is enhanced, and the accuracy of picking is improved.

[0037] The rotating assembly 4 is disposed on the top of the carrier body 1 , and the angle adjustment assembly 5 is disposed on the top of the rotating assembly 4 .

[0038] The rotating assembly 4 includes a fixed frame 41 disposed at the top of the carrier body 1 . A connecting column 45 is rotatably disposed in the fixed frame 41 . A first connecting plate 47 is disposed at the top of the connecting column 45 .

[0039] The angle adjustment assembly 5 includes a support seat 51 arranged at the top end of the first connecting plate 47 , a movable frame 52 is slidably arranged in the support seat 51 , and the bottom end of the telescopic picking rod 3 is connected to the top end of the movable frame 52 .

[0040] The adjusting pruning assembly 6 includes a control device 61 arranged at the top of the telescopic picking rod 3. The output end of the control device 61 is transmission-connected to a second connecting plate 62. The second connecting plate 62 is rotatably provided with two sets of arc-shaped clamping rods 67 for pulling branches.

[0041] The adjusting pruning assembly 6 also includes an electric pruning knife 69 for pruning branches, which is arranged outside the second connecting plate 62. The remote pruning function is realized, and the safety risk in the picking process is reduced.

[0042] Furthermore, the rotating assembly 4 also includes a mounting seat 42 disposed outside the fixed frame 41, a first motor 43 is disposed in the mounting seat 42, a first worm 44 is transmission-connected to the output shaft of the first motor 43, and a first worm wheel 46 meshing with the first worm 44 is fixed outside the connecting column 45. The orientation of the telescopic picking rod 3 is adjusted automatically, thereby improving the adjustment efficiency and accuracy.

[0043] Furthermore, the angle adjustment assembly 5 also includes a half worm gear 53 arranged in the support seat 51, a second worm 54 is rotatably arranged in the movable frame 52, and a second handle 55 is fixed outside the second worm 54, so as to adjust the pitch angle of the telescopic picking rod 3 and allow it to hover at a desired angle.

[0044] Furthermore, the half worm gear 53 meshes with the second worm 54 to assist in completing the dynamic adjustment of the pitch angle.

[0045] Furthermore, a guide track for the movable frame 52 to slide is provided in the support seat 51. The angle of the telescopic picking rod 3 can be finely adjusted to meet the needs of different picking scenes.

[0046] Furthermore, the adjustment pruning assembly 6 also includes a second motor 63 arranged outside the second connecting plate 62, and the output shaft of the second motor 63 is transmission-connected with a first half gear 64, and a second half gear 65 meshing with the first half gear 64 is rotatably arranged in the second connecting plate 62, and a third connecting plate 66 is fixed outside the first half gear 64 and the second half gear 65, and the third connecting plate 66 is movably connected to the arc-shaped clamping rod 67 on the corresponding side, thereby realizing automated clamping and pruning, and improving efficiency and accuracy.

[0047] Furthermore, the adjusting pruning assembly 6 also includes a connecting frame 68 rotatably connected to the arc-shaped clamping rod 67. The connecting frame 68 is rotatably connected to the second connecting plate 62 on the side away from the arc-shaped clamping rod 67, so as to achieve stable pulling of the branches and ensure the cutting effect.

[0048] Furthermore, the electric pruning knife 69 is located between the two sets of arc-shaped clamping rods 67, which is convenient for cutting the branches and is conducive to picking the pomegranates.

[0049] Example 2: Please refer to Fig.10 In combination with the first embodiment, it is further obtained that a pomegranate buffering and collecting assembly 7 for buffering the picked pomegranates is provided at the bottom end of the second connecting plate 62, and the pomegranate buffering and collecting assembly 7 includes a collecting bag 72 for collecting the picked pomegranates. The pomegranate buffering and collecting assembly 7 protects the integrity of the pomegranates during the picking process and reduces damage.

[0050] Further, the pomegranate buffer collection assembly 7 also includes a mounting frame 71 slidably arranged at the bottom of the second connecting plate 62, and the mounting frame 71 is connected to the collecting bag 72 away from the side of the second connecting plate 62. When the collecting bag 72 is greatly worn, the mounting frame 71 can be disassembled to replace the collecting bag 72.

[0051] In actual operation, when pomegranates need to be picked, the operation steps are as follows:

[0052] First, the position of the carrier body 1 is adjusted by adjusting and pulling the first handle 2 so that it reaches the desired picking location. Then, according to the orientation of the pomegranate to be picked, the first motor 43 is started to drive the first worm 44 to rotate, thereby driving the first worm wheel 46 to rotate, so that the connecting column 45 rotates, so that the first connecting plate 47 and the telescopic picking rod 3 rotate as a whole, so as to adjust the orientation of the collecting bag 72. When the telescopic picking rod 3 reaches the orientation of the pomegranate, the first motor 43 is turned off, and the self-locking characteristics of the worm wheel are used to keep the orientation of the telescopic picking rod 3 stable.

[0053] Then, according to the height of the pomegranate, the length of the telescopic picking rod 3 is adjusted so that the collecting bag 72 can be sleeved on the outside of the pomegranate to be picked. If there is a certain angle and distance between the pomegranate and the branches, in order to reduce the risk of the telescopic picking rod 3 breaking during the picking process, the second motor 63 can be started to drive the first half gear 64 to rotate, thereby driving the second half gear 65 meshed therewith to rotate. With the assistance of the third connecting plate 66 and the connecting frame 68, the two sets of arc-shaped clamping rods 67 will move in the center, clamping and pulling the branches close to the electric pruning knife 69. Then the electric pruning knife 69 is started to cut the pulled branches, so that the pomegranate falls into the collecting bag 72. The collecting bag 72 can also buffer the pomegranate and the telescopic picking rod 3 to reduce damage.

[0054] During the picking process, if a pomegranate is not suspended vertically, the pitch angle of the arc-shaped clamping rod 67 and the collecting bag 72 needs to be adjusted. At this time, the second handle 55 can be turned to drive the second worm 54 to rotate. Since the position of the half worm gear 53 is relatively fixed, the movable frame 52 will slide in the guide track of the support seat 51, thereby changing the position of the movable frame 52, and adjusting the pitch angle of the telescopic picking rod 3 to meet the picking needs of pomegranates in different positions.

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
