Description

Technical Field

[0001] This utility model belongs to the field of fruit picking equipment, specifically relating to an anti-collision apple picker. Background Technology

[0002] Fuji apples are widely loved by consumers for their thin skin, juiciness, and crisp flesh. Apple harvesting primarily relies on manual labor. To avoid harvesters having to climb to heights, apple harvesters with handheld poles have emerged on the market. These poles extend the harvesting unit to a higher position where the apples are located for picking. Existing apple harvesters mainly use two types of harvesting units: serrated cutting units connected to a fixed or extendable handheld pole, and claw-type harvesting units. Serrated cutting units have a fruit-collecting bag below them. The serrated cutting unit grips the apple stem for harvesting, and the apple falls into the bag for collection. Claw-type harvesting units, once in position, are closed by the harvester squeezing a handle at the bottom of a long pole, enveloping the apple. The harvester then rotates or pulls down to remove the apple, and releasing the handle causes it to fall into the bag below the claw-type unit. In some cases, the apple is picked by holding the handle together with the claw-type picking unit to deliver it to the ground. Using existing apple pickers requires picking one apple at a time, then retracting the picker to remove the apple, which is inefficient as other personnel then collect and pack the apples into baskets. If multiple apples are picked and allowed to fall into a cloth bag for collection, and then the picker is retracted to remove the apples, the work efficiency can be improved slightly. However, if the apples fall directly into the cloth bag, they are prone to bumping and bruising, especially Fuji apples. Bumping and bruising can cause the apples to be scratched or even broken, which seriously affects the appearance of the apples. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an anti-collision apple harvester, which can effectively improve the harvesting efficiency of apples and avoid the phenomenon of apples being bumped during the harvesting process.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A bump-resistant apple picker includes a handheld rod and a picking unit located at the upper end of the handheld rod. The handheld rod is also equipped with a flexible cushioning bag, the upper end of which is located below the picking unit. The lower end of the flexible cushioning bag is connected to a funnel-shaped elastic cushioning net that is wider at the top and narrower at the bottom. The lower end of the elastic cushioning net is adjacent to the ground. After the picking unit picks the apple, the apple falls into the flexible cushioning bag and slides down the flexible cushioning bag into the elastic cushioning net.

[0006] The harvesting unit includes a mounting base, claws, a pull rod, a reset unit, and a control handle hinged to the hand handle. The mounting base has a cylindrical structure and is connected to the upper end of the hand handle. The flexible cushioning bag is located below the mounting base. The claws are hinged to the mounting base, and the lower end of the claws is located inside the mounting base and connected to the pull rod via a first pull rope. The control handle is connected to the lower end of the pull rod via a second pull rope. The claws have the freedom to close their upper ends by squeezing with the control handle, and the claws have the freedom to automatically reset with the reset unit.

[0007] The handheld lever includes a first upper lever connected to a mounting base, a first lower lever connected to a control handle, and a set of first connecting levers sequentially arranged between the first upper lever and the first lower lever. The first connecting levers are respectively connected to the first upper lever and the first lower lever via a first connecting assembly. The pull rod includes a second upper lever connected to a first pull rope, a second lower lever connected to a second pull rope, and a set of second connecting levers sequentially arranged between the second upper lever and the second lower lever. The second connecting levers are respectively connected to the second upper lever and the second lower lever via a second connecting assembly.

[0008] The first connecting component includes a first external threaded end disposed at the lower end of the first upper rod, the upper end of the first lower rod, and both ends of the first connecting rod, and a first threaded sleeve that matches the first external threaded end. The second connecting component includes a second external threaded end disposed at the lower end of the second upper rod, the upper end of the second lower rod, and both ends of the second connecting rod, and a second threaded sleeve that matches the second external threaded end.

[0009] The outer wall of the mounting base is provided with guide rings that match the first pull rope, and the mounting base and the hand handle are respectively provided with through holes for the first pull rope.

[0010] The reset unit includes a first reset spring and a second reset spring. The two ends of the first reset spring are connected to the mounting base and the claw body, respectively, and the two ends of the second reset spring are connected to the pull rod and the hand handle, respectively.

[0011] The elastic buffer net bag is a double-layered net bag.

[0012] The beneficial effects of this utility model are:

[0013] This invention employs a flexible buffer bag and an elastic buffer net arranged sequentially below the picking unit, allowing the picked apples to slide directly from the tree canopy into the elastic buffer net, eliminating the need for repeated raising and lowering of the picking unit and effectively improving apple picking efficiency. The elastic buffer net is funnel-shaped with an open top and a narrowing bottom, the diameter of which is smaller than the diameter of the apple. After the apple falls to the bottom of the elastic buffer net, it is wrapped by the net, which cushions and absorbs the falling speed, creating resistance to the apple's fall and preventing it from hitting the ground directly.

[0014] The flexible cushioning bag forms a drop channel for apples to fall into the elastic cushioning net. The flexible cushioning bag helps to reduce the length of the elastic cushioning net, so that the elastic cushioning net is located below the tree canopy, preventing the elastic cushioning net from getting caught on the branches and leaves of the apple tree during harvesting.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-3 As shown, an anti-collision apple picker includes a handheld rod 1 and a picking unit disposed at the upper end of the handheld rod 1. A flexible cushioning bag 2 is also disposed on the handheld rod 1, with its upper end located below the picking unit. The lower end of the flexible cushioning bag 2 is connected to a funnel-shaped elastic cushioning net 3, which is wider at the top and narrower at the bottom. The lower end of the elastic cushioning net 3 is adjacent to the ground. After the picking unit picks the apple, the apple falls into the flexible cushioning bag 2 and slides down along it into the elastic cushioning net 3. The flexible cushioning bag 2 is a cloth bag.

[0021] When picking apples, workers hold a handle 1 and extend the picking unit upwards to the location of the apple to pick it. The picked apple falls into a flexible cushioning bag 2 and then falls downwards along the bag. There is no need to retrieve the picking unit to take the apple out. The apple falls along the flexible cushioning bag 2 into an elastic cushioning net 3. Because the elastic cushioning net 3 is funnel-shaped with an open top and a narrowing bottom, and the diameter of the narrowing end is smaller than the diameter of the apple, the apple is wrapped by the elastic cushioning net 3 after falling into it. The elastic cushioning net 3 cushions and absorbs the energy of the falling apple, preventing it from hitting the ground directly and causing damage. Then, other pickers open the bottom of the elastic cushioning net 3 to take out the apple, or simply slide the apple downwards from outside the elastic cushioning net 3. When using this harvester to pick apples, there is no need to frequently move the harvesting unit on the long harvester up and down to pick and place the apples, reducing the difficulty of the work and helping to improve the efficiency of the harvesting work. At the same time, it reduces the probability of the harvester bumping into the apples on the branches when it moves up and down. The flexible cushioning bag 2 forms a falling channel for the apples, allowing the picked apples to slide smoothly into the elastic cushioning net bag 3. The surface of the flexible cushioning bag 2 is flat and soft, so there is no hard impact on the surface of the apples. It also helps to reduce the length of the elastic cushioning net bag 3, so that the elastic cushioning net bag 3 is located below the canopy and prevents the elastic cushioning net bag 3 from getting caught on the branches and leaves of the apple tree during harvesting.

[0022] The harvesting unit includes a mounting base 4, claws 5, a pull rod 6, a reset unit, and a control handle 8 hinged to a handheld rod 1. The mounting base 4 has a cylindrical structure and is connected to the upper end of the handheld rod 1. The flexible cushioning bag 2 is located below the mounting base 4. The claws 5 are hinged to the mounting base 4, and the lower end of the claws 5 is located inside the mounting base 4 and connected to the pull rod 6 via a first pull rope 9. The control handle 8 is connected to the lower end of the pull rod 6 via a second pull rope 10. The claws 5 have the freedom to close their upper ends by squeezing with the control handle 8, and the claws 5 have the freedom to automatically reset via the reset unit. The reset unit includes a first reset spring 12 and a second reset spring 7. The two ends of the first reset spring 12 are connected to the mounting base 4 and the claws 5, respectively. The two ends of the second reset spring 7 are connected to the pull rod 6 and the handheld rod 1, respectively. Specifically, the first reset spring 12 is connected to the lower end of the claws 5, and the first pull rope 9 passes through the first reset spring 12 and is connected to the lower end of the claws 5.

[0023] Move the hand lever 1 so that the open claw 5 is aligned with the apple. The picker squeezes the control handle 8, the pull rod 6 moves down, the lower end of the claw 5 opens outward, the first return spring 12 is compressed, and the upper end of the claw 5 closes to clamp the apple. When the picker is rotated, the apple twists and falls off the branch. Release the control handle 8, the first return spring 12 and the second return spring 7 both return to their original positions. The pull rod 6 moves up and returns to its original position under the action of the second return spring 7. The claw 5 opens under the action of the first return spring 12, and the apple falls from the mounting base 4 into the flexible buffer bag 2.

[0024] In this embodiment, the upper end of the second return spring 7 is fixedly connected to the pull rod 6, and the lower end is fixedly connected to the hand handle 1. When the pull rod 6 moves down, the second return spring 7 is compressed. After the control handle 8 is released, the second return spring 7 pushes the pull rod 6 up to the initial height.

[0025] Furthermore, the handheld lever 1 includes a first upper lever 101 connected to the mounting base 4, a first lower lever 102 connected to the control handle 8, and a set of first connecting levers 103 sequentially disposed between the first upper lever 101 and the first lower lever 102. The first connecting levers 103 are respectively connected to the first upper lever 101 and the first lower lever 102 via a first connecting assembly. The pull lever 6 includes a second upper lever 601 connected to the first pull rope 9, a second lower lever 602 connected to the second pull rope 10, and a set of second upper levers 601 and the second lower lever 602 sequentially disposed between the second pull rope 9 and the second lower lever 602. The second connecting rod 603 is connected to the second upper rod 601 and the second lower rod 602 via the second connecting assembly. The length of the handheld rod 1 can be adjusted by increasing the number of first connecting rods 103 between the first upper rod 101 and the first lower rod 102 via the first connecting assembly. The length of the pull rod 6 can be adjusted by increasing the number of second connecting rods 603 between the second upper rod 601 and the second lower rod 602 via the second connecting assembly, so that the length of the pull rod 6 is adapted to the length of the handheld rod 1, which can meet the harvesting of apples of different heights.

[0026] In this embodiment, the first connecting component includes a first external threaded end 104 disposed at the lower end of the first upper rod 101, the upper end of the first lower rod 102, and both ends of the first connecting rod 103, and a first threaded sleeve 105 mating with the first external threaded end 104. The second connecting component includes a second external threaded end 604 disposed at the lower end of the second upper rod 601, the upper end of the second lower rod 602, and both ends of the second connecting rod 603, and a second threaded sleeve 605 mating with the second external threaded end 604. The threaded connection between the first upper rod 101, the second lower rod 102, and the first connecting rod 103 is achieved through the cooperation of the first threaded sleeve 105 and the first external threaded end 104. This structure is simple, has low manufacturing cost, and enables rapid assembly of the handheld rod 1. The rapid assembly of the pull rod 6 is achieved through the cooperation of the second threaded sleeve 605 and the second external threaded end 604, thereby enabling adjustment of the length of the handheld rod 1 and the pull rod 6.

[0027] Furthermore, guide rings 11 matching the first pull rope 9 are respectively provided on the outer side wall of the mounting base 4. The mounting base 4 and the hand handle 1 are respectively provided with through holes for the first pull rope 9. The first pull rope 9 extends out of the cavity of the hand handle 1 through the through hole on the hand handle 1. The first pull rope 9 enters the mounting base 4 through the through hole on the mounting base 4 and connects to the lower end of the claw body 5.

[0028] The elastic cushioning net bag 3 is a double-layered net bag. The lower end of the double-layered net bag wraps the apple more tightly, further enhancing the resistance of the lower end of the elastic cushioning net bag 3 to the falling apple, increasing the difficulty for the apple to open the lower end of the double-layered net bag, and effectively preventing the apple from falling to the ground and colliding with the ground.
