[0021] Please refer to Figures 1-7 Figures 1-7 , the present utility model provides the following technical solutions: An agricultural picking device, including a mobile base 1, a robotic arm 2, scissors 3 and a placement frame 6, further including a collection box 4, a net bag 5 and a fixing groove 7. On the top of the mobile base 1, there are a robotic arm 2 and a support plate 11. On the support plate 11, there is a feeding port 12. At the top end of the robotic arm 2, scissors 3 are installed. On the top swing arm of the robotic arm 2, there is a collection box 4. On the collection box 4, there is a net bag 5. On the top surface of the mobile base 1, there is an electric telescopic rod 52. At the top of the electric telescopic rod 52, there is a frame 51 hinged. The net bag 5 passes through the frame 51 and is connected to the feeding port 12. On the side wall of the mobile base 1, there is a fixing groove 7. On the fixing groove 7, there is a placement frame 6.

[0022] The mobile base 1 facilitates the user to adjust the position of the device, making it convenient for the user to pick fruits. The scissors 3 can pick the fruits from the plants, realizing the automatic picking of crops. The robotic arm 2 can adjust the position of the scissors 3 so that the scissors 3 can pick the fruits at a suitable angle. After the scissors 3 pick the fruits, the fallen fruits will fall into the net bag 5. The fruits that fall into the net bag 5 will fall into the placement frame 6 through the feeding port 12, realizing the collection of fruits. The collection box 4 is used to fix the net bag 5. The position of the collection box 4 ensures that the opening of the net bag 5 is always below the scissors 3, ensuring the working effect of the net bag 5. The shape of the edge of the collection box 4 is arc-shaped, reducing the damage to the fruits. The frame 51 plays a role in fixing the net bag 5, ensuring the stability of the net bag 5 and facilitating the user to control the moving range of the net bag 5. Through the cooperation of the frame 51 and the electric telescopic rod 52, the position of the net bag 5 can be adjusted. When transporting the picked fruits to the placement frame 6, the robotic arm 2 is lifted, and the collection box 4 drives the net bag 5 to be lifted. At this time, the position of the frame 51 is adjusted through the electric telescopic rod 52 to make the net bag 5 in a smooth inclined state, ensuring the smoothness of the movement of the fruits inside the net bag 5. The frame 51 is hinged on the electric telescopic rod 52, ensuring that after the position of the net bag 5 is adjusted by the device, the frame 51 will not hinder the movement of the fruits inside the net bag 5. The shape of the edge of the feeding port 12 is arc-shaped, avoiding damage to the user caused by the feeding port 12. The fixing groove 7 is used to place the placement frame 6. The fixing groove 7 plays a role of guiding and limiting, ensuring that after the placement frame 6 is placed on the fixing groove 7, the feeding port 12 is located above the placement frame 6, ensuring that the fruits discharged from the feeding port 12 can fall into the placement frame 6. There is a rubber pad on the side wall of the fixing groove 7, improving the friction between the placement frame 6 and the fixing groove 7 and ensuring the stability of the placement frame 6 during the use of the device.

[0023] Specifically, on the inner wall of the frame 51, there is a buffer pad 53, and the width of the buffer pad 53 is greater than the width of the frame 51.

[0024] The buffer pad 53 plays a buffering role, reducing the damage to the fruit when passing through the frame 51. The width of the buffer pad 53 can prevent the fruit from colliding with the edge and side wall of the frame 51 during movement, thereby ensuring the working effect of the buffer pad 53.

[0025] Specifically, a protrusion is provided on the side wall of the fixing block 71, a plurality of grooves matching with the fixing block 71 are provided on the side wall of the fixing groove 7, a spring 72 connected with the grooves on the side wall of the fixing groove 7 is provided on the fixing block 71, and a groove matching with the tip of the fixing block 71 is provided on the side wall of the placement frame 6.

[0026] The locking cam 77 is in the form of a latching member 72 which is secured on the locking cam 74 so that the locking cam 74 will be in the unlocked position if the locking cam 72 is engaged.

[0027] Specifically, the material of the net bag 5 has a certain elasticity.

[0028] The material of the net bag 5 ensures that the robot arm 2 will not be hindered by the net bag 5 during movement. The stretchable net bag 5 reduces the length of the net bag 5 when not subjected to external force and avoids the movement of the fruit inside the net bag 5 being hindered due to the excessive length of the net bag 5 when not stretched.

[0029] Specifically, a mounting frame 41 is provided on the top rocker arm of the robot arm 2 , and the collection frame 4 is hinged on the mounting frame 41 . An electric winding shaft 43 is provided on the mounting frame 41 , and the electric winding shaft 43 is connected to the collection frame 4 through a pull wire 42 .

[0030] The collecting frame 4 is hinged on the mounting frame 41, and the electric winding shaft 43 is connected to the collecting frame 4 through the pull wire 42. The electric winding shaft 43 realizes the winding and releasing of the pull wire 42. During the movement of the pull wire 42, the collecting frame 4 is rotated with it, thereby realizing the adjustment of the inclination angle of the collecting frame 4. During the process of picking the fruits with the scissors 3, the inclination angle of the collecting frame 4 is adjusted to ensure that the fallen fruits can fall smoothly into the net bag 5, thereby ensuring the working effect of the collecting frame 4.

[0031] Specifically, a guide wheel 44 is installed on the mounting bracket 41. The wire 42 bypasses the guide wheel 44, and the side wall of the guide wheel 44 is in an arc shape that is recessed inward.

[0032] The guide wheel 44 can change the movement trajectory of the wire 42, ensuring that the position of the electric wire reel 43 can be as far away from the robotic arm 2 as possible, reducing the influence of the electric wire reel 43 on the robotic arm 2. The shape of the side wall of the guide wheel 44 ensures the stability of the wire 42 during movement.

[0033] Specifically, symmetric T-shaped protrusions are provided on the bottom surface of the placement frame 6, and grooves matching the protrusions on the bottom surface of the placement frame 6 are provided on the top surface of the moving base 1.

[0034] The cooperation between the protrusions on the bottom surface of the placement frame 6 and the grooves on the top surface of the moving base 1 plays a guiding role, facilitating the user to install the placement frame 6 on the moving base 1. The shape of the protrusions on the bottom surface of the placement frame 6 ensures the stability of the placement frame 6 after it is installed on the support plate 11.

[0035] The working principle and usage process of the present utility model: The placement frame 6 is placed on the moving base 1 through the cooperation between the protrusions on the bottom surface of the placement frame 6 and the grooves on the top surface of the moving base 1. Push the placement frame 6, and the placement frame 6 enters the fixing groove 7. During the process of the placement frame 6 entering the fixing groove 7, it will push the fixing block 71. After the placement frame 6 completely enters the fixing groove 7, the fixing block 71 returns to its original position under the action of the spring 72. The placement frame 6 is fixed through the cooperation between the side wall grooves and the fixing block 71. The device is moved to the vicinity of the plant to be picked through the moving base 1. The scissors 3 are adjusted to a suitable position through the robotic arm 2. The electric wire reel 43 is started, and the inclination angle of the collection frame 4 is adjusted through the wire 42. The scissors 3 are started, and the cut fruits fall into the interior of the net bag 5 through the collection frame 4. When transporting the fruits, the robotic arm 2 is lifted, and the height of the electric telescopic rod 52 is adjusted to make the net bag 5 in a smoothly inclined state, ensuring the smoothness of the movement of the fruits inside the net bag 5. The fruits move inside the net bag 5, and finally the fruits fall into the interior of the placement frame 6 through the feeding port 12.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
