The specific working principle of the portable fruit picking device 10 is as follows:
when picking fruit, the operator holds the support rod 200 with the right hand (or left hand), holds the handle 110 with the left hand (or right hand), pulls the trigger 120 to rotate the trigger 120 relative to the handle 110, and since one end of the pull rod 300 is connected with the trigger 120, the pull rod 300 is driven to move downwards when the trigger 120 rotates, and the other end of the pull rod 300 is connected with the end cover 422, the outer sleeve 420 is driven to move downwards when the pull rod 300 moves downwards.
In the process that the outer sleeve 420 continuously moves downwards, the conical surface 423 touches the top cap 450 and presses the top cap 450 to generate a pressure, one component of the pressure compresses the top spring 440, and the other component of the pressure drives the top cap 450 to move downwards and simultaneously drives the inner sleeve 430 connected with the top cap 450 to move downwards. When the inner sleeve 430 moves downwards, the mechanical fingers are pulled by the first pull wire 510 to rotate relative to the base 710, so that the mechanical fingers are closed to grasp the fruit.
When the mechanical fingers grip the fruit and the mechanical fingers exert pressure on the fruit to a certain extent, that is, when the inner sleeve 430 is pulled by the first pull wire 510 to a certain extent, the force applied from the top cap 450 to the inner sleeve 430 is sufficiently overcome, so that the inner sleeve 430 stops moving downward. While the outer sleeve 420 continues to move downward along with the pull rod 300, the inner sleeve 430 and the outer sleeve 420 have relative movement, the top cap 450 continues to move along the conical surface 423, and the top spring 440 continues to be pressed to deform. The second pulling wire 520 connected to the outer sleeve 420 pulls the first link 610 to rotate the first link 610, and the first link 610 rotates to drive the second link 620 and the fixing rod 630 to rotate, so that the picking head assembly 700 is disposed on the fixing rod 630, and the picking head assembly 700 can rotate around the fruit as a center to pick the fruit.
The trigger 120 is turned, the pull rod 300 stops moving downward, and the clutch assembly 400 stops moving. When the trigger 120 is released, the trigger 120 is reset under the restoring force of the first restoring torsion spring 130, the first connecting rod 610 is reset under the restoring force of the second restoring torsion spring 640, the pull rod 300 is reset under the restoring force of the top spring 440, the mechanical finger is reset under the restoring force of the restoring spring 720, and the mechanical finger is opened to wait for the next picking action.
Above-mentioned portable fruit picking device 10 is through being equipped with clutch assembly 400 between first acting line 510, second acting line 520 and pull rod 300 to control the dynamics of snatching fruit, prevent to cause the damage to the fruit epidermis, realize using the fruit to be the mode of centering rotation picking fruit through adopting link assembly 600, is favorable to protecting the fruit tree, so can effectively avoid damaging fruit and can effectively protect the fruit tree when improving picking efficiency.
