In the embodiment of the present invention, the picking mechanism 2 is welded to the connecting bridge 14, so that the picking mechanism 2 is fixed between the No. 1 hull 11 and the No. 2 hull 12. The mechanical arm 23 is connected to the screw lifting mechanism 24 by welding. When the mechanical arm 23 picks the target crop, if the height of the mechanical arm 23 is not enough, the image transmitter 22 works, thereby driving the mechanical arm 23 to rise as a whole. The mechanical claw 21 is connected to the mechanical arm 23 by screws, and the image transmitter 22 is placed in the mechanical claw 21, and can follow the movement of the mechanical claw 21, so as to obtain a wide field of view and the position of the target crop, and realize accurate picking. When in use, after the target crop position is determined by the image transmission 22, the mechanical arm 23 moves to the predetermined position, and the mechanical claw 21 starts to pick the target crop. After picking, the mechanical arm 23 moves to place the target crop into the cargo hold 31.

[0049] It can be understood that the image transmission 22 includes: an image acquisition module and an image micro-processing module, which uses the image acquisition module to acquire an image of the target crop to obtain a target image, transmits the target image to the image micro-processing module, and uses the image micro-processing module after receiving the target image to parse the target image to obtain a positioning signal of the target crop, which is sent to the electronically controlled integrated module box 53, and uses the electronically controlled integrated module box 53 after receiving the positioning signal of the target crop to control the robotic gripper 21.

In the embodiment of the present invention, the storage mechanism 3 is placed in the middle of the catamaran floating mechanism 1, and the two sides are fixed to the No. 1 hull 11 and the No. 2 hull 12 by screws through the guide rails 37, and the hydraulic cylinder 36 is fixed on the guide rails 37. When in use, the hydraulic rod 36 is controlled by the hydraulic cylinder 36 to reciprocate along the axial direction of the hydraulic cylinder 36. The cargo hold connecting rod 34 connects the hydraulic cylinder 36 and the lifting arm 33, and the lifting arm 33 is welded to the cargo hold frame 32. Therefore, the reciprocating motion of the hydraulic rod 36 enables the lifting arm 33 to reciprocate along a straight line. The cargo hold 31 is directly mounted on the cargo hold frame 32, and the cargo hold frame 32 can rotate around the guide rail 3 according to the end of the guide rail 37 away from the picking mechanism 2, thereby realizing the function of dumping the cargo in the cargo hold 31.

[0052] Specifically, the wind drive mechanism 4 includes a steering gear bracket 45 provided on the flying wing 13, and a steering gear 43 built into the steering gear bracket 45, and the steering gear 43 is fixedly provided with four copper pillars 44 close to the side of the steering gear bracket 45 and a steering gear 42 away from the side of the steering gear bracket 45, and also includes a wind propeller 41 provided on the steering gear 42. In the embodiment of the present invention, the wind propeller 41 is fixedly connected with the steering gear 42, and is fixed to the flying wing 13 by screws through four copper pillars 44 and the steering gear bracket 45. The wind propeller 41 is tightly connected with the steering gear 42 to ensure the precise steering of the wind-driven catamaran. The steering gear 43 is built into the steering gear bracket 45, and the steering gear 43 drives the steering gear 42 to rotate, and the steering gear 42 drives the wind propeller 41 to rotate, thereby realizing the steering function.

[0053] Furthermore, the detection and electric control mechanism 5 includes an electric control integrated module box 53 fixedly mounted on the second hull 12, and a pressure sensor 54 mounted on the cargo hold 31, and also includes a detection radar 51 and a support 52 mounted on the second hull 12 away from the end of the flying wing 13, and an infrared sensor 55 is also mounted on the cargo hold 31. In the embodiment of the present invention, the detection radar 51 is supported by the support 52 and fixed to the end of the second hull 12 away from the flying wing 13 by screws.

[0054] It is understandable that in the embodiment of the present invention, the electric control integrated module box 53 includes: a central control module, a motor drive module, a GPS module, an image transmission microprocessor module and an information conversion module.

[0055] Specifically, the mechanical gripper 21 includes a steering gear B212 disposed on the mechanical arm 23, and a turntable 215 rotatably disposed on the steering gear B212, a rotating rod 214 rotatably disposed on the turntable 215, three gripper arms 213 rotatably disposed on the rotating rod 214, and a steering gear A211 disposed on the rotating rod 214, and further includes a steering gear A211 connected to the three gripper arms 213, wherein the steering gear A211 rotates to drive the rotating rod 214 to rotate, and drives the three gripper arms 213 to open and close according to the direction of rotation of the rotating rod 214. In the embodiment of the present invention, when the steering gear A211 rotates, it drives the rotating rod 214 to rotate, and the rotating rod 214 rotates so that the distance from the end of the rotating rod 214 away from the center increases or decreases, thereby driving the three gripper arms 213 to open and close. When the three gripper arms 213 grab and completely surround the target crop, the servo B212 rotates to drive the turntable 215 to rotate, so that the gripper arms 213 rotate. In the embodiment of the present invention, saw teeth are also provided at the front end of the gripper arms 213, so that the gripper arms 213 can apply torque to the stems of the target crop, cut off the stems with the saw teeth, and achieve the picking of the target crop.

[0056] Preferably, the mechanical arm 23 includes a rotating member 233 fixedly arranged on the wheel circle 25, and two steering gear discs 235 symmetrically arranged on the rotating member 233, and also includes a steering gear housing 234 arranged on the steering gear disc 235, a steering gear C231 is arranged inside the steering gear housing 234, and a steering gear D232 is also arranged on the steering gear housing 234, wherein the mechanical arm 23 includes eight identical units, and a wheel circle 25 is arranged between every two adjacent identical units. In the embodiment of the present invention, each of the eight identical units includes: a steering gear C231, a steering gear D232, two rotating members 233, two steering gear housings 234 and two steering gear discs 235. The two steering gear housings 234 are connected end to end and fixed by screws, and the steering gear C231 and the steering gear D232 are fixed by screws and two steering gear housings 234. When the servo C231 and the servo D232 rotate, the servo disc 235 is driven to rotate, and since the servo disc 235 and the rotating member 233 are fixed by screws, the rotation of the servo disc 235 enables the rotating member 233 to turn. It can be understood that each of the eight identical units is linked by its own rotating member 233, so that the mechanical arm 23 has multiple degrees of freedom and can reach any position in space.

[0057] Furthermore, the screw lifting mechanism 24 includes a top plate 248 fixedly mounted on the wheel circle 25 away from the robotic arm 23, three screw rods 245 are fixedly mounted on the top plate 248, each of the three screw rods 245 is provided with a nut 246, an end of the nut 246 away from the screw rod 245 is provided with a gear 244, and a gear B243 cooperated with the gear 244, the gear B243 is cooperated with a gear A242, the gear A242 is provided with a chassis 247, and also includes a stepper motor 241 arranged on a side of the chassis 247 away from the gear A242, wherein each of the three screw rods 245 is provided with a gear 244, the three gears 244 are all cooperated and connected with the gear B243, and the three gears 244, the gear B243 and the gear A242 are all arranged on the same side of the chassis 247 away from the stepper motor 241.

Finally, the three screw rods 245 rotate with the rotation of the stepper motor 241, so that the top plate 248 rises or falls.

[0058] It should be noted that in the embodiment of the present invention, the detection and electrical control mechanism 5, the wind drive mechanism 4, the storage mechanism 3, the steering gear 43 and the motor are all connected with relays, each relay is respectively connected to the motor drive module on the hull, the motor drive module is connected to the steering gear 43 of the steering gear 42, and the central control module is wirelessly connected to the user end.

[0059] During use, taking the picking of lotus pods as an example, the image transmission 22 starts working. After the image transmission 22 identifies the lotus pods to be picked, the mechanical claw 21 moves to the top of the lotus pods. When the mechanical claw 21 is closed, it can clamp the lotus pod stems. At this time, the steering gear A211 drives the mechanical claw 21 to rotate to achieve the cutting of the lotus pod stems. After the cutting is completed, the lotus pods are transported to the top of the storage mechanism 3 by the mechanical claw 21 under the movement of the mechanical arm. Further, the mechanical claw 21 opens and the lotus pods fall into the cargo compartment 31 of the storage mechanism 3. The detection and electronic control mechanism 5 starts working in real time, and the pressure sensor 54 and the infrared sensor 55 will measure the mass and volume of the lotus pods in the cargo compartment 31. When the mass of the lotus pods reaches the maximum loading mass, the pressure sensor 54 generates full load information and sends it to the electronic control integrated module box 53, or when the volume of the lotus pods reaches the maximum loading volume, the infrared sensor 55 returns the full load information to the electronic control integrated module box 53. When the electronic control integrated module box 53 receives the full load information, it controls the mechanical claw 21 to close. After the mechanical claw 21 is closed, the wind drive mechanism 4 starts to work, and the two steering gears 42 respectively twist the two wind propellers 41 to complete the turning action and drive the wind-driven catamaran to return.

[0060] Furthermore, the detection and electric control mechanism 5 guides the crop picking boat on the water to accurately travel and dock at the predetermined position. After arriving at the predetermined position, the central control module sends arrival information to the user end. After the user end manipulates the catamaran to accurately dock at the loading and unloading position, the storage mechanism enters the unloading process and the cargo hold is tilted for unloading.

[0061] Example 2

[0062] As a second embodiment of the present invention, this embodiment is used to realize the control function of an electronically controlled integrated module box 53 in a mechatronic catamaran suitable for water crop picking. Through dual detection by laser and vision, the waterway and surrounding environment information is obtained in real time to guide the wind-driven catamaran to travel normally, including: using the detection radar 51 to scan the surrounding environment to obtain a contour map of the surrounding environment and point cloud information of the target crop position, using the pre-constructed information acquisition and conversion module in the electronically controlled integrated module box 53 to receive and process the contour map of the surrounding environment and the point cloud information of the target crop position, and obtain a three-dimensional point cloud map including the waterway status, wherein the electronically controlled integrated module box 53 includes: a central control module, a motor drive module, a GPS module, a picture transmission microprocessor module and an information conversion module.

[0063] It is understandable that in the embodiment of the present invention, after receiving the operation instruction initiated by the user end, the central control module is started, so that the wind propeller 41 and the steering gear 42 are started, and the waterway and surrounding environment information are monitored, the surrounding environment is scanned, and the contour map of the surrounding environment and the point cloud information of the target crop position are obtained. The information acquisition conversion module pre-built in the electronic control integrated module box 53 receives and processes the contour map of the surrounding environment and the point cloud information of the target crop position, and obtains a three-dimensional point cloud map including the waterway status. The user makes adjustments and corrections according to the three-dimensional point cloud map. After arriving at the operating position, the wind propeller 41, the steering gear 42, the image transmission 22 cooperate with the detection radar 51 to accurately park in the operating position, and fine-tune the posture of the wind-driven catamaran to facilitate the operation of the picking mechanism 2. At this time, the wind propeller 41 enters the low power consumption mode, the GPS module and the detection radar sleep to save energy, the mechanical arm starts, and the picking operation begins. The image transmission 22 sends the collected positioning signal of the target crop to the mechanical arm 23, and the mechanical arm 23 picks the target crop and puts it into the storage mechanism 3. When the storage mechanism sends the full load information to the central processor, the electronic control integrated module transmits the full load information back to the user end and sends a stop command to the picking mechanism 2, and the robotic arm 23 returns to its position. At the same time, the storage mechanism 3 and the picking mechanism 2 go into sleep mode to save energy, the GPS module and the detection radar 51 are activated, and the wind-driven catamaran returns.

[0064] Furthermore, the wind-driven catamaran stops after reaching the return position. The central control module sends arrival information to the user end, and the user end manipulates the catamaran to accurately dock at the loading and unloading position. The storage mechanism 3 is activated and enters the unloading process, and the cargo hold is tilted for unloading.

[0065] Specifically, after unloading is completed, the storage mechanism 3 returns to its original position, the user terminal sends a shutdown command, and the central control module cuts off the power to all mechanisms.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
