[0028] The utility model aims to provide a tea picking device to solve the problems existing in the prior art and achieve accurate tea picking. At the same time, the overall structure is simple, easy to load and unload, and has good adaptability.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figure 1-Figure 5 As shown, the present embodiment provides a tea picking device, comprising a base 9, a driving mechanism, a transmission mechanism, a storage box and a picking mechanism. The driving mechanism, the transmission mechanism and the storage box are arranged in sequence and installed on the upper end of the base 9, so that the tea picking device in the present embodiment can be detachably installed on various tea picking robots through the base 9, and has good adaptability. The output shaft of the driving mechanism is connected to the input shaft of the transmission mechanism, and the output end of the transmission mechanism is connected to the picking mechanism. The picking mechanism is installed on the storage box, and the picking side of the picking mechanism is arranged away from the driving mechanism. The transmission mechanism is driven to move by the driving mechanism, and the picking mechanism can be opened and closed and complete the picking action under the drive of the transmission mechanism. When the picking mechanism is opened, it can prevent interference from non-picked tea leaves. When the picking mechanism is closed, tea leaves can be picked, and the picked tea leaves fall into the storage box, so as to realize temporary storage of the picked tea leaves.

[0031] Specifically, the upper end surface of the base 9 is provided with a mounting groove, in which a bracket plate 7 is installed, and the driving mechanism is installed on the bracket plate 7 to improve the installation stability.

[0032] The driving mechanism includes a stepper motor 1 and a coupling 2. The stepper motor 1 is mounted on the upper end surface of the base 9. The coupling 2 is connected between the output shaft of the stepper motor 1 and the input shaft of the transmission mechanism. The power of the stepper motor 1 is transmitted to the transmission mechanism through the coupling 2 to achieve torque transmission. The stepper motor 1 is electrically connected to the controller and realizes forward and reverse rotation through the instructions of the controller.

[0033] The transmission mechanism includes a fixed-end bearing 3, a supporting-end bearing 4, a ball screw 5, a nut 8, a slider 27 and an action module. A fixed seat 30 is installed on the end of the base 9 away from the driving mechanism. The fixed-end bearing 3 and the supporting-end bearing 4 are both installed on the upper end surface of the base 9, and the supporting-end bearing 4 is arranged close to the fixed seat 30. One end of the ball screw 5 is connected to the driving mechanism, and the other end of the ball screw 5 is rotatably connected to one side of the fixed seat 30. The fixed-end bearing 3 and the supporting-end bearing 4 are both sleeved on the outer periphery of the ball screw 5 and are respectively arranged close to the two ends of the ball screw 5, so as to support the ball screw 5 and improve the structural stability. The nut 8 is sleeved on the outer periphery of the ball screw 5, and the slider 27 is installed on the upper end of the nut 8. One end of the action module is connected to the slider 27, and the other end of the action module is connected to the picking mechanism. The action module can drive the picking mechanism to open and close as the nut 8 moves, and complete the picking action. When the stepper motor 1 is working, it can drive the ball screw 5 to rotate, and the rotation of the ball screw 5 is converted into a linear movement of the nut 8 and the slider 27, and then through the forward and reverse rotation of the stepper motor 1, the picking mechanism is driven to open and close to complete the picking action.

[0034] The action module includes a large belt cover 15, a belt body 14 and a small belt cover 16. The large belt cover 15 is installed on the upper end of the nut 8, and the small belt cover 16 is installed on the upper end of the picking mechanism. One end of the belt body 14 is fixed to the nut 8 through the large belt cover 15, and the other end of the belt body 14 is fixed to the picking mechanism through the small belt cover 16. The large belt cover 15 and the small belt cover 16 play a role in fixing the belt body 14 to ensure that the belt body 14 can move with the linear movement of the nut 8.

[0035] An idler wheel 10 is rotatably mounted on the upper end of the fixing seat 30 , and the belt body 14 is located above the idler wheel 10 and contacts the outer periphery of the idler wheel 10 , thereby ensuring stable rotation of the belt body 14 .

[0036] An extension opening is provided at the upper end of the storage box, and a picking opening is provided on the side of the storage box away from the driving mechanism. The picking mechanism is installed in the storage box, and the picking side of the picking mechanism is located at the picking opening. The side walls of the storage box located on both sides of the picking opening are a left transparent cover plate 22 and a right transparent cover plate 23, respectively, which is convenient for observing the tea leaves in the storage box and achieving accurate picking.

[0037] The picking mechanism includes a moving blade 6, a stationary blade 12, a picking blade 20 and a spring 18. The stationary blade 12 is mounted on the lower bottom surface of the storage box, and the blade edge of the stationary blade 12 is located at the picking port. The moving blade 6 is bent, and both ends of the moving blade 6 extend in a direction close to the lower bottom surface of the storage box. One end of the moving blade 6 is hinged to the fixing seat 30 through a bearing 28, and the picking blade 20 is mounted on the other end of the moving blade 6. The moving blade 6 and the stationary blade 12 can be detachably connected to the storage box. The spring 18 is mounted on one side of the storage box close to the driving mechanism, and the lower end of the spring 18 is mounted on the upper end surface of the stationary blade 12, and the upper end of the spring 18 is mounted on the lower end of the moving blade 6. The small belt cover 16 is mounted on the middle part of the moving blade 6, so that when the belt body 14 moves, the moving blade 6 can be driven to rotate, and the picking blade 20 can be moved in a direction close to or away from the stationary blade 12, and the spring 18 can be reset or extended. When the picking blade 20 contacts the stationary blade 12, tea leaves can be picked.

[0038] When the stepper motor 1 reverses, the ball screw 5 is driven to rotate synchronously through the coupling 2. At the same time, the rotation of the ball screw 5 is converted into the linear motion of the nut 8 (the nut 8 moves in the direction close to the stepper motor 1), and the nut 8 drives the slider 27 to move in the direction close to the stepper motor 1. Under the action of the idler wheel 10, the belt body 14 is driven to move in the direction close to the stepper motor 1, so that the movable blade 6 rotates in the direction away from the stationary blade 12, and the opening action is realized, so that the tea leaves to be picked can be inserted into the storage box, so as to realize the subsequent picking action. At the same time, the spring 1 8 is in a stretched state; when the stepper motor 1 rotates forward, the ball screw 5 is driven to rotate synchronously through the coupling 2, and at the same time, the rotation of the ball screw 5 is converted into a linear motion of the nut 8 (the nut 8 moves away from the stepper motor 1), and the nut 8 drives the slider 27 to move away from the stepper motor 1. Under the action of the idler wheel 10, the belt body 14 is driven to move away from the stepper motor 1, so that the moving blade 6 rotates in the direction close to the stationary blade 12, and the closing action is realized, thereby realizing the picking of tea leaves. At the same time, in this process, the spring 18 is reset.

[0039] This embodiment also includes a shell 29, which is installed on the base 9, and a receiving cavity is formed between the shell 29 and the base 9. The driving mechanism and the transmission mechanism are both located inside the receiving cavity and protected by the shell 29. The storage box is located on the outer wall of the receiving cavity and on one side of the shell 29 to facilitate picking.
