Picking begins, and the sector gear 5-9 is not meshed with the large gear 5-7. The fruit containing plate 2-2 is placed below the fruits to be picked, the motor 2-9 is started to drive the roller 2-11 to rotate, so that the third rope body 2-12 is driven to shorten, the shearing device 1 is pulled to move along the connecting block 2-5, and the second spring 1-15 stores elastic force. If the fruit stalks to be picked do not face the blade outlets 1-11, the fruit stalks move along the oblique angles 1-10 while the shearing device 1 moves along the connecting blocks 2-5, meanwhile, the shearing device 1 and the fruit containing device 2 are pushed to move along the connecting plates 3-3 together, the third springs 3-1 or the fourth springs 3-2 are compressed, the fruit stalks to be picked are ensured to slide into the effective shearing space formed by the blade outlets 1-11, accurate positioning of the fruit stalks is achieved, and then the fruit containing device 2 returns to the initial position through the third springs 3-1 and the fourth springs 3-2. When the shear device frame 1-12 is in contact with the limit switch 2-3, the motor 2-9 stops moving.
Then, an operator operates the operation handle 5-8 to enable the operation handle 5-8 to rotate around the supporting rod 5-10, meanwhile, the torsion spring 5-11 is driven to rotate together to store spring force, at the moment, the sector gear 5-9 is meshed and matched with the large gear 5-7 to drive the large gear 5-7 to rotate, the wire barrel 5-6 rotates around the wire barrel 5-4, the second rope body 5-12 is wound on the wire barrel 5-6 to drive the first rope body 1-8 to move, the sliding block 1-6 is driven to move, the connecting rod 1-5 is driven to move, the first spring 1-7 is stretched to store spring force, the connecting rod 1-5 pushes the blade 1-4 to extend out of the blade outlet 1-11 to cut off fruit handles, and fruits drop into the fruit containing device 2. When the operating handle 5-8 is loosened, the spring force stored by the torsion spring 5-11 when the pulling force of the third rope body 2-12 is eliminated enables the operating handle 5-8 to reset, meanwhile, the first spring 1-7 is stretched by the stored spring force to enable the blade 1-4 to return to the initial position, the second spring 1-15 is acted to enable the shearing device 1 to return to the initial position, and the fruit picking process is completed once.
The application is applicable to the prior art where it is not described.
