Figure 9 As shown, the packaging bag 11 is torn open; at this time, the teeth of the transmission rack 21 disengage from the gear shift wheel 22, and the untoothed part of the transmission rack 21 contacts the gear shift wheel 22. Then, push rod 15 continues to move to the left following drive plate 4. Push rod 12 drives drive rod 16 to move to the left, and drive rod 16 drives feed plate 19, connecting plate 20 and transmission gear 21 to move to the left until drive plate 4 drives the two clamping plates 6 to fully fit together through slide groove 8, clamping the fruit stem. Figure 3 As shown; At this point, the opening of the bag with strap 11 is stretched to its maximum, such as Figure 10 As shown, the packaging bag 11 is located directly below the pear; Finally servo cylinder 5 drive plate 4 to the right movement, drive plate 4 on the slide 8 drive two clamping plate 6 away from each other, so that the pear clamping in the two clamping plate 6 loose; At the same time drive plate 4 drive push rod 15 to the right movement, push rod 15 on the push rod 12 to the left slide, until the push rod 15 to the second baffle 14, push rod 15 through the second baffle 14 drive push rod 12 to the right movement, push rod 12 drive drive rod 16, first heating plate 17, connecting plate 20, transmission gear bar 21 restore position, first heating plate 17 and second heating plate 18 contact, circuit, will be bag 11 bag opening for compression sealing; Then through the external power supply start electric heating block 27, the plastic on the packaging bag 11 melt, through the external mechanical hand will be placed in the packaging bag 11 pear to the storage box 26.
[0021] Through 19, the use of electric heating block 27 and fixed rod 10, can be fixed rod 10 on the packaging bag 11 pull open, then through the first heating plate 17 and the second heating plate 18, the use of hot pressing plastic package 11, so that the pear fall into the packaging bag 11 packaging, ensure that the pear in the picking process, no protection, resulting in skin damage, form scratch, indentation damage, avoid microbial infection, accelerate the decay of metamorphic conditions occur, at the same time, after picking the packaging of pear does not need to be packaged, simplify the work flow, save manpower and time cost, suitable for large scale pear picking packaging production needs.
[0022] The raw material of the packaging bag 11 is kraft paper and plastic film hot-pressed on the kraft paper, and the raw material at the upper end of the packaging bag 11 is plastic.
[0023] The adhesive block on the feeding plate 19 is a solid reusable adhesive block, such as a silicone-based adhesive block.
[0024] As a further scheme of the present application, the picking vehicle 1 comprises a placing plate 25 capable of telescoping in the vehicle body 1, and a storage box 26 for storing pears is placed on the placing plate 25.
[0025] As a further scheme of the present application, the diameter of the electric heating block 27 is smaller than the diameter of the fixed rod 10, and a anti-falling ring is arranged at the end of the electric heating block 27 away from the fixed rod 10 to prevent the packaging bag 11 from falling off.
[0026] As a further scheme of the present application, a semicircular groove is arranged on the side of the packaging bag 11 inserted into the fixed rod 10, which can accelerate the melting speed of the packaging bag 11 during work.
[0027] As a further scheme of the present application, the transmission gear bar 21 and the drive rod 16 are both provided with local teeth.
[0028] Working principle: asFigure 1 As shown, the telescopic plate 3 is started, the telescopic plate 3 moves the clamping plate 6 and the blade 7 to the fruit stem of the pear, then the servo cylinder 5 is started, the output shaft of the servo cylinder 5 pushes the driving plate 4 to move left, the sliding groove 8 on the driving plate 4 drives the relative movement of the two clamping plates 6, the fruit stem is clamped, then the driving plate 4 continues to move, the blade 7 cuts off the fruit stem, at this time, the fruit stem is clamped by the two clamping plates 6, so that the pear is prevented from falling, and the effect of automatic picking of the pear is realized; After the driving plate 4 drives the clamping plate 6 and the blade 7 to cut off the fruit stem of the pear from the tree, the fruit stem is clamped by the clamping plate 6 during the process; As Figure 2 With Figure 4 As shown, the driving plate 4 drives the two push rods 15 to push the first baffle 13 to move left, since the first baffle 13 is fixed with the push rod 12, the push rod 15 drives the push rod 12 to move left through the first baffle 13, the push rod 12 drives the driving rod 16 to move left, so that the first heating plate 17 is separated from the second heating plate 18; As Figure 5 As shown, during the left movement of the driving rod 16, the driving rod 16 drives the driving wheel 23 to rotate counterclockwise, the driving wheel 23 drives the speed change wheel 22 to rotate clockwise, the speed change wheel 22 drives the transmission tooth rod 21 to move right, the upper end of the transmission tooth rod 21 drives the connecting plate 20 to move right through the extrusion of the first spring 24, so that the feeding plate 19 moves right, and the adhesive block on the feeding plate 19 is adhered to the outer side of the packaging bag 11, as shown in Figure 8 ; Then, during the continuous left movement of the connecting plate 20, the teeth on the connecting plate 20 are disengaged from the meshing with the driving wheel 23; without the action of the gear, the torsional spring built in the driving wheel 23 makes the driving wheel 23 rotate back to the initial position, the driving wheel 23 drives the speed change wheel 22 to rotate back to the initial position during the rotation, the speed change wheel 22 drives the transmission tooth rod 21 to move left, the transmission tooth rod 21 drives the connecting plate 20 to move left, and the connecting plate 20 drives the feeding plate 19 to move left; since one side of the packaging bag 11 is adhered to the feeding plate 19, the packaging bag 11 can move left with the feeding plate 19 during the left movement of the feeding plate 19; When the packaging bag 11 moves left to the electric heating block 27 from the fixed rod 10, as shown in Figure 6 Since the hole opened on the back of the packaging bag 11 is matched with the fixed rod 10, the electric heating block 27 is provided with an anti-falling ring to prevent the packaging bag 11 from falling off the fixed rod 10, therefore, during the left movement of the packaging bag 11, the back of the packaging bag 11 is blocked by the electric heating block 27, and the feeding plate 19 can only pull one side of the packaging bag 11 to the outside, as shown in Figure 9As shown, the packaging bag 11 is torn open; at this time, the teeth of the transmission tooth bar 21 are disengaged from the meshing of the gear wheel 22, and the rear end of the transmission tooth bar 21 is not in contact with the gear wheel 22; Then the push rod 15 continues to follow the driving plate 4 to move left, the push rod 12 drives the driving rod 16 to move left, the driving rod 16 drives the feeding plate 19, the connecting plate 20 and the transmission tooth bar 21 to move left, until the driving plate 4 drives the two clamping plates 6 to completely adhere through the sliding groove 8, and the fruit stem is clamped, as shown in Figure 3 As shown; At this time, the bag opening of the packaging belt 11 is stretched to the maximum, as shown in Figure 10 The packaging bag 11 is located directly below the pear; Finally, the servo cylinder 5 drives the driving plate 4 to move right, the sliding groove 8 on the driving plate 4 drives the two clamping plates 6 to move away from each other, so that the pear clamped between the two clamping plates 6 is loosened; at the same time, the driving plate 4 drives the push rod 15 to move right, the push rod 15 slides left on the push rod 12 until the push rod 15 moves to the second baffle 14, the push rod 15 drives the push rod 12 to move right through the second baffle 14, the push rod 12 drives the driving rod 16, the first heating plate 17, the connecting plate 20 and the transmission tooth bar 21 to return to the original position, the first heating plate 17 contacts the second heating plate 18, the circuit is connected, the bag opening of the packaging bag 11 is pressed and sealed;
