The working process of the oil tea fruit picking machine is completely explained as follows:
the handheld handle 47 drives the walking vehicle 1 to enable the walking vehicle 1 to move to the position of tea trees to be picked. Then adjust picking head 3's position through adjustment mechanism, make picking head 3 go up and down and reach near the branch that needs to pick the tea-oil camellia fruit, the concrete operation is as follows: the hand wheel 18 is rotated manually, the hand wheel 18 rotates to drive the screw 16 to rotate, and the nut connecting rod 17 moves horizontally after the screw 16 rotates and stretches relative to the screw 16. After the nut connecting rod 17 moves horizontally, the first connecting rod assembly 10 and the second connecting rod assembly 11 are close to or far away from each other, the third connecting rod assembly 12 and the fourth connecting rod assembly 13 are close to or far away from each other, the fifth connecting rod assembly 14 and the sixth connecting rod assembly 15 are close to or far away from each other, meanwhile, the sliding block 7 slides up and down on the lower frame body 4, the upper frame body 5 rotates relative to the lower frame body 4 finally through the movement of the components, therefore, the upper end of the upper frame body 5 ascends and descends, and the picking heads 3 mounted on the upper end of the upper frame body 5 also ascend and descend. When the picking heads 3 ascend and descend to correspond to branches needing to pick the oil tea fruits, the hand wheels 18 are stopped from rotating, and then the picking of the oil tea fruits can be started.
Starting the power device 29, which drives the intermediate chain wheel 32 to rotate by the first chain 33, and then simultaneously driving the conveying transmission gear 24 and the picking transmission gear 28 to rotate by the second chain 34 after the intermediate chain wheel 32 rotates, i.e. the rubber roller assembly 2 and the picking head 3 are simultaneously driven:
(1) after the rubber roller assembly 2 is driven, the camellia oleifera fruit branches to be picked are conveyed towards the upper end of the lifting frame/picking head 3: the transmission gear 24 drives the rotary table 20 to rotate, the rubber roller 23 on the rotary table 20 performs circular motion to convey the camellia oleifera fruit branches to be picked towards the picking head 3, and the rubber roller 23 performs circular motion and simultaneously rotates to avoid damage to the camellia oleifera fruit branches caused by rotation of the rubber roller 23.
(2) Picking head 3 is driven and then claw rack 41 rotates and cutter rack 40 continuously swings back and forth towards left and right sides: after the picking transmission gear 28 rotates, the picking transmission gear 25 drives the two side frame plates 26 to rotate, the claw rack 41 is driven to rotate on one side after the side frame plates 26 rotate, and on the other side, the bearing 45 fixedly connected with the side frame plates 26 can do circular motion along the side wall of the circular ring guide rail at the same time. After the claw rack 41 rotates, the oil tea fruit on the branch conveyed by the rubber roller 23 is clamped between the two adjacent claw racks 41, and when the claw rack 41 collides with a thick branch, the claw rack 41 stretches to rotate the tension spring 42 and rotates to stick to the bottom of the branch to bypass the branch, so that the claw rack 41 is prevented from rotating to cause damage to the branch, and the claw rack 41 can reset under the action of the tension spring 42 after bypassing the branch. In the process that the bearing 45 does circular motion along the side wall of the circular ring guide rail, when the bearing 45 moves to the position of the notch 46, the bearing 45 slides into the notch 46 under the action of the swinging tension spring 38 and enables the swinging sliding plate 37 to swing towards one side, so that the cutter rack 40 arranged on the swinging sliding plate 37 synchronously swings towards one side, the cutter rack 40 can cut off the fruit stem of the oil tea fruit clamped by the claw rack 41 after swinging towards one side, and finally the oil tea fruit falls off from the branches to finish picking. The bearing 45 slides out of the notch 46 along the inclined surface of the notch 46 and swings towards the other side when continuing circular motion along the side wall of the circular guide rail, and the cutter rack 40 arranged on the swing sliding plate 37 synchronously swings towards the other side for resetting so as to prepare for picking again.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
