[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1-8This embodiment is an apple-picking robot, including a walking mechanism 100, a lifting mechanism 200, a robotic arm picking mechanism 300, and an auxiliary mechanism 400. The walking mechanism 100 includes a base plate 101 and four wheel hub frames 102 disposed at the bottom end of the base plate 101. Wheels 103 are rotatably disposed on the four wheel hub frames 102. The lifting mechanism 200 includes a first limiting frame 201 disposed at the top of the base plate 101. A lifting component 202 is disposed within the first limiting frame 201.

The robotic arm picking mechanism 300 includes a lifting plate 204 disposed on the lifting plate 204. The base rotation motor 301 is located at the top, and its output end is connected to the bottom end of the first robotic arm 302. A joint motor 303 is provided on one side of the top of the first robotic arm 302, and a second robotic arm 304 is provided on the other side of the top of the first robotic arm 302. The end of the second robotic arm 304 is connected to the output end of the joint motor 303, and a gripping component 305 is provided on the other end of the second robotic arm 304.

The base rotation motor 301 and the joint motor 303 are electrically connected to the controller 403.

[0027] The walking mechanism 100 transports the entire device to the apple tree. The lifting component 202 raises the lifting plate 204, which in turn raises the robotic arm picking mechanism 300 to the desired picking position. The base rotation motor 301 in the robotic arm picking mechanism 300 can drive the first robotic arm 302 to rotate 360 ​​degrees. The joint motor 303 on one side of the top of the first robotic arm 302 can drive the second robotic arm 304 to rotate at a certain angle. When the end of the second robotic arm 304 is close to the apple to be picked, the gripping component 305 at the end of the second robotic arm 304 is controlled to pick the apple.

[0028] In this embodiment, a drive motor 104 is provided on one side of each of the four wheel hub frames 102. The output end of the drive motor 104 is connected to the wheel 103. The four drive motors 104 are electrically connected to the controller 403. The controller 403 is a single-chip microcomputer with model MPC89L515AP.

[0029] The controller 403 controls the activation of the drive motors 104 on the four wheel hub brackets 102 to provide forward power for this application. When there is a speed difference between the drive motors 104 on the left and right sides, steering control can be performed.

[0030] In this embodiment, the first limiting frame 201 and the second limiting frame 203 are rectangular frames. The first limiting frame 201 includes a first limiting plate 201a and a second limiting plate 201b spaced apart. The two sides of the first limiting plate 201a and the second limiting plate 201b are connected by a third limiting plate 201c and a fourth limiting plate 201d, respectively. The opposite end faces of the third limiting plate 201c and the fourth limiting plate 201d are respectively provided with a first limiting groove 201e. The second limiting frame 203 includes a fifth limiting plate 203a and a sixth limiting plate 203b spaced apart. The two sides of the fifth limiting plate 203a and the sixth limiting plate 203b are connected by a seventh limiting plate 203c and an eighth limiting plate 203d, respectively. The opposite end faces of the seventh limiting plate 203c and the eighth limiting plate 203d are respectively provided with a second limiting groove 203e.

[0031] In this embodiment, the lifting assembly 202 includes two pairs of first scissor mechanisms and second scissor mechanisms arranged vertically. The second scissor mechanism includes a first support rod 202a and a second support rod 202b that are hinged to each other in an "X" shape. A connecting rod 202c is connected between the lower ends of the two second support rods 202b. A first limiting post 202d is provided at both ends of the connecting rod 202c. The first limiting post 202d is slidably disposed in a first limiting groove 201e. The lower ends of the two first support rods 202a are respectively hinged to a first limiting plate 201a. Two first connecting plates 202e are connected between the two first support rods 202a at intervals.

[0032] In this embodiment, the first scissor mechanism includes a third support rod 202g and a fourth support rod 202h that are interlocked and hinged in an "X" shape. The lower ends of the third support rod 202g and the fourth support rod 202h are respectively hinged to the upper ends of the first support rod 202a and the second support rod 202b. The upper ends of the two fourth support rods 202h are respectively hinged to the fifth limiting plate 203a. The upper ends of the two third support rods 202g are respectively provided with second limiting posts 202i, which are slidably disposed in the second limiting grooves 203e. Two second connecting plates 202j are spaced apart between the two third support rods 202g.

[0033] In this embodiment, a transmission assembly 205 is provided at the top of the base plate 101 located inside the first limiting frame 201. The transmission assembly 205 includes a transmission motor 205a and a first bearing seat 205b disposed at the top of the base plate 101, and a second bearing seat 205c disposed at the end face of the second limiting plate 201b. A threaded seat 205d is sleeved on the outer wall of the connecting rod 202c. A threaded rod 205e is connected to the output end of the transmission motor 205a. The threaded rod 205e is threadedly connected to the threaded seat 205d. The outer wall of the threaded rod 205e is fixed in the inner ring of the first bearing seat 205b and the second bearing seat 205c. The transmission motor 205a is electrically connected to the controller 403.

[0034] The controller 403 activates the drive motor 205a, which drives the threaded rod 205e to rotate, thereby causing the threaded seat 205d to move axially along the threaded rod 205e. When the threaded seat 205d moves toward the drive motor 205a, it drives the connecting rod 202c to move toward the drive motor 205a. The threaded seat 205d, through the connecting rod 202c, drives the first limiting posts 202d at both ends to slide within the first limiting groove 201e of the first limiting frame 201. The included angle between the first support rod 202a and the second support rod 202b decreases, thereby driving the third support rod 202g and the fourth support rod 202h to move in the same direction. As the included angle between the two third support rods 202g decreases, the second limiting post 202i at the upper end of the two third support rods 202g slides in the second limiting groove 203e, thus driving the second limiting frame 203 and the lifting plate 204 to rise in height. If the transmission motor 205a is reversed, the threaded seat 205d moves away from the transmission motor 205a, and the threaded seat 205d drives the connecting rod 202c to move away from the transmission motor 205a. The included angle between the first support rod 202a and the second support rod 202b increases, which in turn drives the included angle between the third support rod 202g and the fourth support rod 202h to increase, and the height of the second limiting frame 203 and the lifting plate 204 decreases.

[0035] In this embodiment, the gripping component 305 includes a mounting block 305a disposed on one side of the end of the second robotic arm 304. A rotary motor 305b is fixed on the mounting block 305a. The output end of the rotary motor 305b is connected to a mounting frame 305c. Two spaced circular fixing blocks 305d are disposed on one side of the mounting frame 305c. The two circular fixing blocks 305d are connected by a plurality of circumferentially arranged connecting posts 305e. Three connecting blocks 305f are circumferentially arranged on the side wall of the outer circular fixing block 305d. The top two sides of the three connecting blocks 305f are respectively hinged to one end of two connecting rods 305g. The other ends of the two connecting rods 305g are respectively hinged to the bottom two sides of the clamping claw 305h. The rotary motor 305b is electrically connected to the controller 403.

[0036] In this embodiment, a push-pull block 305i is provided at the bottom center of the three locking claws 305h. Three push-pull rods 305j are respectively circumferentially hinged to the side wall of the push-pull block 305i. The end of the push-pull rod 305j away from the push-pull block 305i is hinged to the middle of the connecting rod 305g. An electric push rod 305k is provided on the other side of the mounting bracket 305c. The push-pull shaft of the electric push rod 305k passes through two circular fixing blocks 305d and is fixedly connected to the push-pull block 305i. The electric push rod 305k is electrically connected to the controller 403.

[0037] When the three clamping claws 305h at the end of the second robotic arm 304 approach the apple, the controller 403 controls the push-pull shaft of the electric push rod 305k to pull the push-pull block 305i. The push-pull block 305i, under the force of the pullback, will pull the three push-pull rods 305j. The three push-pull rods 305j will then pull the connecting rod 305g to rotate around the connecting block 305f, thereby causing one end of the three clamping claws 305h to move closer to each other until they clamp the base of the apple. Then, the controller controls the rotary motor 305b to drive... The mounting bracket 305c rotates, which in turn drives the three locking claws 305h to rotate, breaking off the branches at the base of the apple tree. Then, the push-pull shaft of the electric push rod 305k is controlled to push the push-pull block 305i. The push-pull block 305i, under the force of the push, will push the three push-pull rods 305j. The three push-pull rods 305j will then push the connecting rod 305g to rotate outward around the connecting block 305f, thereby causing one end of the three locking claws 305h to move away from each other. At this point, the apple can be removed.

[0038] In this embodiment, the drainage component 402 includes a small water pump 402a disposed inside the cabinet 401. The outlet end of the small water pump 402a is connected to a water pipe 402b. One end of the water pipe 402b extends out of the top of the cabinet 401 and is provided with a shower nozzle 402c. A material basket 401a is provided at the top of the cabinet 401, and a water inlet 401b is opened on one side of the top of the cabinet 401.

[0039] After picking, the apples are placed in the container basket 401a, and the small water pump 402a is turned on. The small water pump 402a outputs water from the cabinet 401 along the water pipe 402b to the shower nozzle 402c to perform a preliminary cleaning of the picked apples.

[0040] Working principle: The controller 403 controls the activation of the drive motors 104 on the four wheel hubs 102 to provide forward propulsion. When there is a speed difference between the drive motors 104 on the left and right sides, steering control can be performed. After the walking mechanism 100 transports the entire device to the apple tree, when it is necessary to raise the height of the lifting plate 204, the controller 403 activates the transmission motor 205a. The transmission motor 205a drives the threaded rod 205e to rotate, which in turn drives the threaded seat 205d to move along the axial direction of the threaded rod 205e. When the threaded seat 205d moves towards the transmission motor 205a, the threaded seat 205d drives the connecting rod 202c to move towards the direction of the transmission motor 205a. The threaded seat 205d moves through the connecting rod 202c. c drives the first limiting post 202d at both ends to slide within the first limiting groove 201e of the first limiting frame 201. The included angle between the first support rod 202a and the second support rod 202b decreases, which in turn drives the included angle between the third support rod 202g and the fourth support rod 202h to decrease. The second limiting post 202i at the upper end of the two third support rods 202g slides within the second limiting groove 203e. Therefore, it can drive the second limiting frame 203 and the lifting plate 204 to be raised. The base rotation motor 301 in the robotic arm picking mechanism 300 can drive the first robotic arm 302 to rotate 360 ​​degrees. The joint motor 303 on one side of the top of the first robotic arm 302 can drive the second robotic arm 304 to rotate at a certain angle, so that... When the three gripping claws 305h in the end-grip assembly 305 of the second robotic arm 304 approach the apple to be picked, the push-pull shaft of the electric push rod 305k pulls the push-pull block 305i. The push-pull block 305i, under the force of the pull, pulls the three push-pull rods 305j. The three push-pull rods 305j then pull the connecting rod 305g to rotate around the connecting block 305f, thereby causing one end of the three gripping claws 305h to move closer together until they clamp the root of the apple. Then, the rotary motor 305b drives the mounting frame 305c to rotate. The mounting frame 305c drives the three gripping claws 305h to rotate, breaking off the branches at the root of the apple. Then, the push-pull shaft of the electric push rod 305k pushes the push-pull block 305i. The push-pull block 305i, under the force of the push, will... Pushing the three push-pull rods 305j, the three push-pull rods 305j in turn push the connecting rod 305g to rotate outward around the connecting block 305f, thereby causing one end of the three locking claws 305h to move away from each other, at which point the apple can be removed. When the operation is finished and the height of the lifting plate 204 needs to be lowered, the control drive motor 205a is reversed, and the threaded seat 205d moves away from the drive motor 205a. The threaded seat 205d drives the connecting rod 202c to move away from the drive motor 205a, the included angle between the first support rod 202a and the second support rod 202b increases, thereby causing the included angle between the third support rod 202g and the fourth support rod 202h to increase, and the height of the second limit frame 203 and the lifting plate 204 to decrease.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
