The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0023] As Figures 1 to 4 shown, a fruit and vegetable picking machine of the present utility model includes: a picking vehicle 1, a picking robotic arm 2, a collection component 3 disposed on the picking vehicle 1 for collecting the picked fruits and vegetables, and a picking component 4 disposed on the picking robotic arm 2 for picking the fruits and vegetables;

[0024] The collection component 3 includes: a collection box 301 fixedly installed on the picking vehicle 1 for collecting fruits and vegetables, a tray 302 slidably installed inside the collection box 301, a first guide rod 303 for guiding the moving tray 302, and a first spring 304 for driving the tray 302 to reset.

[0025] The picking component 4 includes: a first limiting plate 401, first connecting ears 4011 symmetrically installed on the first limiting plate 401, a second limiting plate 402, second connecting ears 4021 symmetrically installed on the second limiting plate 402, a second guide rod 403 fixedly installed on the first connecting ear 4011, both ends of the second guide rod 403 are fixedly installed on the first connecting ear 4011 through positioning blocks, a guide sleeve 404 slidably installed on the surface of the second guide rod 403, a cutter 406 fixed on the guide sleeve 404, a hinge rod 405 hingedly installed between the guide sleeve 404 and the adjacent second connecting ear 4021, an installation block is fixedly installed at the top of the second connecting ear 4021, both ends of the hinge rod 405 are respectively hingedly installed on one side of the adjacent guide sleeve 404 and one side of the adjacent installation block, so that the hinge rod 405 is horizontally arranged, when the second limiting plate 402 approaches the first limiting plate 401, the hinge rod 405 can push the cutter 406 at the top of the guide sleeve 404 to move towards the root of the fruits and vegetables to cut the fruits and vegetables, an electric push rod 407 fixedly installed on the first connecting ear 4011 to drive the second limiting plate 402 to move, the output end of the electric push rod 407 is fixedly connected to one side of the adjacent second connecting ear 4021, and a buffer component 5 arranged on the inner walls of the first limiting plate 401 and the second limiting plate 402 to collect the cut fruits and vegetables.

[0026] The buffer component 5 includes: a fixed block 501 fixedly installed on the first limiting plate 401 and the second limiting plate 402, a movable rod 502 movably penetrating through the fixed block 501, a tray 503 fixedly installed on the movable rod 502, and a second spring 504 sleeved on the surface of the movable rod 502, one end of the second spring 504 is fixedly connected to the bottom of the tray 503, and the other end of the second spring 504 is fixedly connected to the top of the fixed block 501.

[0027] When the picking robotic arm 2 moves to the position of the fruits and vegetables to be picked, at this time the fruits and vegetables are located between the first limit plate 401 and the second limit plate 402. The output ends of two electric push rods 407 drive the second connecting lugs 4021 on both sides of the second limit plate 402 to approach the first limit plate 401, so that the two supporting plates 503 approach each other. At this time, the hinge rod 405 hinged between the second limit plate 402 and the first limit plate 401 pushes the guide sleeve 404 slidably mounted on the surface of the second guide rod 403 to move, so that the guide sleeve 404 drives the cutter 406 to cut the fruit stalk of the fruits and vegetables. The cut fruits and vegetables fall between the two supporting plates 503 for collection. When the fruits and vegetables fall, through the setting of the second spring 504, it plays a buffering role for the cut fruits and vegetables, and can effectively prevent the damage of the fruits and vegetables.

[0028] Both sides of the tray 302 are fixedly connected with connecting blocks 3021, and the middle part of the connecting block 3021 penetrates through the upper end of the first guide rod 303. One end of the first spring 304 is fixedly installed with the bottom of the connecting block 3021, and the other end of the first spring 304 is fixedly connected with the surface of the picking vehicle 1.

[0029] When the number of fruits and vegetables placed on the top of the tray 302 is small, the first spring 304 pushes the tray 302 to move upward through elastic reset, so that when the picking robotic arm 2 places the picked fruits and vegetables, the distance between the tray 302 and the fruits and vegetables placed by the picking robotic arm 2 is reduced, and further the height of the falling fruits and vegetables is too high to cause damage, affecting the picking quality.

[0030] Working principle: Connect the power supply. When the picking vehicle 1 moves to the fruit and vegetable picking position and picks the fruits and vegetables through the picking robotic arm 2, at this time the fruits and vegetables are located between the first limit plate 401 and the second limit plate 402. The output ends of two electric push rods 407 drive the second connecting lugs 4021 on both sides of the second limit plate 402 to approach the first limit plate 401, so that the two supporting plates 503 approach each other. At this time, the hinge rod 405 hinged between the second limit plate 402 and the first limit plate 401 pushes the guide sleeve 404 slidably mounted on the surface of the second guide rod 403 to move, so that the guide sleeve 404 drives the cutter 406 to cut the fruit stalk of the fruits and vegetables. The cut fruits and vegetables fall between the two supporting plates 503 for collection. When the fruits and vegetables fall, through the setting of the second spring 504, it plays a buffering role for the cut fruits and vegetables, and can effectively prevent the damage of the fruits and vegetables. The picked fruits and vegetables are then placed on the top of the tray 302 by the picking robotic arm 2. When the number of fruits and vegetables placed on the top of the tray 302 is small, the first spring 304 pushes the tray 302 to move upward through elastic reset, so that when the picking robotic arm 2 places the picked fruits and vegetables, the distance between the tray 302 and the fruits and vegetables placed by the picking robotic arm 2 is reduced, so as to avoid the height of the falling fruits and vegetables being too high to cause damage, affecting the picking quality.
