Description

Technical Field

[0001] The present invention relates to the technical field of crop picking equipment, and particularly to a pineapple picking execution manipulator and a picking device. Background Art

[0002] As a tropical specialty fruit, the picking process of pineapples has long relied on manual operation. However, the leaves of pineapple plants are sharp, the fruits grow in a concealed manner and are mostly located on hilly slopes, resulting in low manual picking efficiency, high labor intensity and easy stabbing. With the acceleration of the agricultural modernization process, the traditional manual picking mode has been difficult to meet the needs of large-scale planting. Coupled with the problems of rising labor costs and labor shortages caused by the concentrated harvest period, it is urgent to break through the bottleneck through mechanization and intelligent technology.

[0003] When the existing pineapple picking manipulator picks pineapples, it generally clamps the pineapples and then separates the stem and the fruit stalk of the pineapples by twisting. The above device has the following obvious defects when in use: First, there is a problem of damage to the fruits with rigid clamping. And in order to ensure the maturity of pineapples when sold, pineapples are generally picked when the maturity of the pineapple fruits is relatively low (generally 7-8 mature). For pineapples with relatively low maturity, their stems have not become brittle yet, and it is very difficult to separate the pineapples by twisting, and the picking effect is unstable.

[0044] The pneumatic drive mechanism includes an electromagnetic opening valve 1-29 and a pneumatic telescopic rod 30. The electromagnetic opening valve 1-29 is connected to the air outlet of the air storage tank 28. The electromagnetic opening valve 1-29 is connected to the pneumatic telescopic rod 30 through a pipeline.

The pneumatic telescopic rod 30 controls its expansion and contraction through compressed air.

[0048] Working principle: During use, the position of the pineapple is identified through the camera 9. After the pineapple is identified, the clamping angle of the clamping jaw 5 is adjusted through the angle adjustment motor 17 and the torsion motor 19. Then, the pineapple is clamped by the clamping jaw 5. After the clamping is completed, the electromagnetic opening valve 1-29 is opened and the cutting knife 6 is driven by the pneumatic telescopic rod 30 to cut the stem of the pineapple. At the same time, the torsion motor 19 drives the clamping jaw 5 to rotate to pick the pineapple. After the picking is completed, the flipping motor 10 is started to flip the mounting bracket 4. When the mounting bracket 4 moves above the pineapple box 3, the clamping jaw 5 will release the clamping to release the pineapple into the glass box. Then, the flipping motor 10 drives the mounting bracket 4 to reset;

[0049] When the flipping motor 10 drives the first parallel rod group 11 to move, it will drive the piston 25 to reciprocate in the cylinder 27 through the connecting rod 24. At this time, the air is compressed into the air storage tank 28;

[0050] Before clamping the pineapple, a part of the air in the air storage tank 28 is input into the airbag 7 through the electromagnetic opening valve II 31. When the angle sensor 14 detects that the mounting bracket 4 moves above the pineapple frame 3 (which means the pineapple is released into the pineapple frame 3), the pressure relief valve I 33 will open to clean the clamping jaw 5.

[0051] After stably clamping the pineapple, a part of the air in the air storage tank 28 is input into the pneumatic telescopic rod 30 through the electromagnetic opening valve I 29 to drive the cutting knife 6 to cut the stem of the pineapple. When the angle sensor 14 detects that the mounting bracket 4 rises, the pressure relief valve II 34 opens, and under the drive of the return spring 35, the air in the pneumatic telescopic rod 30 is sprayed onto the cutting knife 6 to clean the cutting knife 6.
