Description

Technical Field

[0001] The invention relates to the technical field of coconut picking tools, in particular to a coconut picking knife. Background Art

[0002] The best time to pick fresh coconut fruit is when the coconut meat is concentrated at 5 mm in the coconut fruit body, which is also the heaviest time for the coconut fruit. After searching, the Chinese invention patent with application number CN202210651535.X discloses a cinnamon new shoot bud leaf harvesting device, which can realize the continuous completion of the picking and collection of cinnamon tea new shoot bud leaves, improve the picking efficiency, and reduce the jamming phenomenon when picking the cinnamon tea new shoot bud leaves.

[0003] When the above device is used to pick heavy objects such as coconuts, it is necessary to continuously use a large force to squeeze. When the coconut is not cut directly in one go, the knife clamp is easily stretched open after the picker releases the knife clamp. When the picker squeezes the knife clamp again, there is a path where the knife clamp needs to be pushed to move repeatedly. Although the knife clamp encounters less resistance during this process, the side surface will still rub against the coconut stalk, which increases the physical exertion of the picker and reduces the maximum picking amount of the picker. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a coconut clamp knife, which solves the technical problem that the existing coconut picking clamp knives are easily stretched open after being loosened during the picking process, causing the pickers to push the clamp knife to repeatedly move a certain path when squeezing the clamp knife again, increasing the friction between the clamp knife and the coconut stalk, and causing increased physical exertion of the pickers.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a coconut knife clamp, comprising two main handles rotatably connected to each other, one end of the main handle is fixedly connected to a clamping plate, the bottom of the main handle is fixedly connected to a ring, and a limit position component is installed between the two rings; The limiting assembly includes an arc block that movably passes through the two circular rings, and both ends of the arc block are fixedly connected with hemispheres, one of the hemispheres is fixedly connected to the circular rings, and a plurality of limiting grooves are opened on the top of the arc block, and a sway preventing assembly is installed inside the limiting grooves. The sway preventing assembly has a first position and a second position. In the first position, the sway preventing assembly is inside the limiting groove, and in the second position, the sway preventing assembly extends out of the limiting groove to prevent the two circular rings from moving away.

[0006] Furthermore, the sway prevention assembly includes a slider slidably connected to the inner wall of the limiting groove, a notch is provided at the top of the slider, a magnetic metal block is rotatably connected to the inner bottom of the notch, and a magnet block extending into the interior of the slider is provided at the top of the slider.

[0007] Furthermore, one side of the slider is provided with a threaded rod with one end movably extending into the interior thereof, and one end of the threaded rod away from the slider is fixedly connected to a rubber block.

[0008] Furthermore, an elastic sheet is fixedly connected to the top of the magnet block, and anti-slip strips are fixedly connected to both sides of the elastic sheet.

[0009] Furthermore, a rubber block 2 is installed on one side of the clamping plate, and a clamping assembly for fixing the rubber block 2 is installed on the outer side of the clamping plate.

[0010] Furthermore, the clamping assembly includes a limit frame sleeved on the outside of the clamping plate and the second rubber block, the width of the limit frame close to the second rubber block is greater than the width of the limit frame away from the second rubber block, and the side of the limit frame close to the second rubber block is provided with a bolt with one end movably penetrating the limit frame.

[0011] Furthermore, a through hole penetrating the hemisphere is provided on one side of the hemisphere, and a traction rope with both ends movable and penetrating the through hole of the hemisphere is provided between the two main handles, and one end of the traction rope is fixedly connected to the limiting ball.

[0012] Furthermore, a torsion spring is installed between the two main handles, a circular hole corresponding to the torsion spring is opened on one side of the main handle, and both ends of the torsion spring are movable through the circular hole of the main handle.

[0013] By means of the above technical solution, the present invention provides a coconut clamp knife, which has at least the following beneficial effects: 1. The present invention can limit the distance of the coconut clamping knife by setting a limiting component by using the pickers to shake the coconut clamping knife, so that the distance of the clamping knife will not be expanded after being released, and the coconut picking clamping knife can be prevented from being easily stretched after being released during the picking process, causing the pickers to push the clamping knife to repeatedly move a path when squeezing the clamping knife again, increasing the friction between the clamping knife and the coconut stalk, and causing the pickers to consume more physical energy.

[0014] 2. The traction rope provided in the present invention can conveniently control the speed at which the picked coconuts fall to the ground, is suitable for picking coconuts with a large weight, and can reduce the possibility of damage to the coconuts when they fall and accidental injury to people on the ground.

[0015] 3. The present invention provides a threaded rod and a rubber block to facilitate and flexibly adjust the overall length of the sway prevention assembly, so that the sway prevention assembly can adapt to the limit groove that is depressed and deformed after being squeezed, thereby reducing the possibility that the sway prevention assembly can be easily pushed out of the limit groove after the limit groove is squeezed and deformed.

[0016] 4. The elastic sheet and anti-slip strip provided in the present invention reduce the difficulty of controlling the magnetic metal block to move to the outside of the limiting groove to achieve the limiting effect on the main handle. At the same time, it is also convenient to remove the magnet block from the slider, so that the magnet block can be recovered when the slider is severely squeezed and damaged.

[0017] 5. The present invention can improve the firmness of the connection between the coconut and the clamping knife after the coconut is picked by setting the rubber block 2 and the clamping assembly, reduce the possibility of the clamping knife falling off the coconut, and facilitate ground personnel to control the slow falling of the picked coconut when pulling the clamping knife through the traction rope.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1 In order to allow coconut pickers to pause when using the clamp knife to cut the coconut stalk, so that the pickers can accumulate strength and use force again, and at the same time prevent the clamp knife from being stretched out during the pause, please refer to Figure 1-Figure 6 The present embodiment proposes a coconut clamp knife, comprising two main handles 1 rotatably connected to each other, one end of the main handle 1 is fixedly connected to a clamping plate 2, the bottom of the main handle 1 is fixedly connected to a ring 3, a limiting component 4 is installed between the two rings 3, the limiting component 4 comprises an arc block 41 that movably passes through the two rings 3, both ends of the arc block 41 are fixedly connected to a hemisphere 42, one of the hemispheres 42 is fixedly connected to the ring 3, a plurality of limiting grooves are provided on the top of the arc block 41, a shaking blocking component 43 is installed inside the limiting groove, which can extend out of the limiting groove to prevent the two rings 3 from moving away after shaking in the plane where the main handle 1 is located, and the shaking blocking component 43 has a first position and a second position, The sway blocking component 43 is in the limit groove in the first position, and extends out of the limit groove in the second position to prevent the two rings 3 from moving away. When in use, the sway blocking component 43 is in the limit groove in a natural state, and the pickers can move the main handle 1 that is not fixed to the hemisphere 42 toward the other main handle, driving the two clamps to approach each other to clamp off the coconut stalks, thereby realizing the picking process. Since the force required to clamp off the coconut stalks is relatively large, the pickers consume too much physical energy after working for a period of time. In the subsequent picking process, it is easy to find it difficult to clamp off the coconut stalks in one go to complete the picking process. It is usually necessary to rest halfway through the clamping knife to clamp off the coconut stalk and then drive the clamping knife again with force.

[0022] When the pickers need to take a break while using the clamp knife, they first maintain the clamp knife's grip on the coconut stalk, and then shake the main handle 1 left and right along the plane where the clamp knife is located, driving the arc block 41 to shake until the shaking blocking component 43 is shaken to the outside of the limiting groove. At this time, the pickers can release the main handle 1, and when the squeezed coconut stalk pushes the two main handles 1 to open, increasing the distance between the two main handles 1, the main handle 1 is blocked by the shaking blocking component 43 extending to the outside of the limiting groove, causing the distance between the two main handles 1 to be unable to continue to increase, thereby maintaining the distance between the two main handles 1 when the pickers take a break, waiting for the pickers to squeeze the clamp knife again, or when the clamp knife needs to be removed from the coconut stalk, the pickers can The pickers shake the clamp knife to shake the shaking blocking component 43 back into the limiting groove, or the pickers continue to squeeze the two main handles 1 closer to each other, and push the shaking blocking component 43 between the two main handles 1 into the limiting groove, until the two main handles 1 drive the two clamping plates 2 to approach to a certain degree and cut the coconut stalk, completing the coconut picking process. The pickers can use the coconut clamp knife to limit the distance of the clamp knife, so that the distance of the clamp knife will not be expanded after the clamp knife is released, preventing the coconut picking clamp knife from being easily stretched after it is released during the picking process, causing the pickers to push the clamp knife to repeatedly move a path when squeezing the clamp knife again, increasing the friction between the clamp knife and the coconut stalk, and increasing the physical exertion of the pickers.

[0023] In order to enable the coconut knife clamp to limit the position of the two main handles 1 when necessary, and not affect the movement of the two main handles 1 at ordinary times, refer to Figure 3 and Figure 4 The sway prevention assembly 43 includes a slider 431 slidably connected to the inner wall of the limiting groove, a notch is provided on the top of the slider 431, a magnetic metal block 432 is rotatably connected to the inner bottom of the notch, and a magnet block 433 extending to the inside of the slider 431 is provided on the top of the slider 431. When in use, the magnet block 433 attracts the magnetic metal block 432 to approach the slider 431, so that the magnetic metal block 432 stays inside the limiting groove, and will not prevent the rings 3 on the two main handles 1 from moving along the arc block 41. When it is necessary to prevent the distance between the two splints 2 from increasing, only The coconut pickers shake the main handle 1 back and forth along the plane where the main handle is located, driving the arc block 41 and the magnetic metal block 432 to shake, so that the magnetic metal block 432 overcomes the attraction of the magnet block 433 during the shaking process and moves away from the slider 431. Finally, one end of the magnetic metal block 432 extends to the outside of the limiting groove. When the distance between the two main handles 1 increases, the two main handles 1 can only move away from a smaller distance, and the bottom ring 3 will be blocked by the magnetic metal block 432 extending to the outside of the limiting groove, thereby stopping the distance between the two main handles 1 from expanding.

[0024] When the pickers continue to use the clamping knife to cut off the coconut stalk, the coconut pickers push the two main handles 1 together to push the magnetic metal block 432 into the limiting groove, ensuring that the magnetic metal block 432 extending to the outside of the limiting groove can block the two clamps 2 from moving away without blocking the two clamps 2 from getting closer. When there is no need to block the distance between the two clamps 2 from increasing, the coconut pickers only need to drive the two main handles 1 a short distance away from the magnetic metal block 432. The magnetic metal block 432 will be attracted to the inside of the limiting groove under the action of the magnetic field of the magnet block 433, and will no longer block the increase in the distance between the two main handles 1, allowing the clamping knife to easily meet the limiting requirements.

[0025] In order to more smoothly transport the coconuts picked from the coconut trees to the ground, refer to Figure 1 A through hole penetrating the hemisphere 42 is provided on one side of the hemisphere 42, and a traction rope 11 with two ends movably penetrating the through holes of the hemisphere 42 is provided between the two main handles 1. One end of the traction rope 11 is fixedly connected to a limiting ball 12. When in use, the traction rope 11 passes around the leaf support of the coconut tree and extends to the ground. The ground staff pulls the end of the traction rope 11 away from the clamping knife. After the coconuts on the coconut tree are picked, the two clamping plates 2 stay on the picked coconut fruit stalks and are driven by the coconuts to fall downward. In this process, the ground staff slowly releases the traction rope 11, so that the traction rope 11 controls the clamping knife and the coconuts on the clamping knife to slowly fall to the ground, and finally sorts the coconuts on the ground and cuts excess branches, which is convenient for controlling the speed at which the picked coconuts fall to the ground. It is suitable for picking coconuts with heavier weights and can reduce the possibility of damage to coconuts when they fall and accidental injury to ground personnel.

[0026] To facilitate the use of coconut clip knife, refer to Figure 1 A torsion spring 13 is installed between the two main handles 1, and a round hole corresponding to the torsion spring 13 is opened on one side of the main handle 1. Both ends of the torsion spring 13 can move through the round hole of the main handle 1. When in use, the torsion spring 13 pushes the two main handles 1 to open, driving the two splints 2 to open. When it is necessary to pick coconuts, the pickers push the two main handles 1 gradually closer to squeeze and bend the torsion spring 13. After the coconuts are picked, the pickers no longer squeeze the main handles 1, and the torsion spring 13 pushes the two main handles to open to the initial position.

[0027] Embodiment 2 Since the magnetic metal block 432 blocks the two main handles 1 from being stretched apart, it will be squeezed to one side, and the force of the magnetic metal block 432 being squeezed by the main handle will eventually act on the inner wall of the limit groove, causing the limit groove to be concave and deformed. In order to reduce the shaking of the limit groove after the deformation and squeezing of the blocking component 43, refer to Figure 1-Figure 6On the basis of the first embodiment, one side of the slider 431 is provided with a threaded rod 5 with one end movably extending into the interior thereof, and the end of the threaded rod 5 away from the slider 431 is fixedly connected with a rubber block 6. When in use, the threaded rod 5 is rotated to drive the rubber block 6 away from the slider 431 until the thickness of the rubber block 6 moves to the outside of the slider 431 to be the same as the thickness of the limit groove being squeezed and depressed, and then the slider 431 is placed in the limit groove, and the rubber block 6 and the slider 431 are tightly against the inner wall of the limit groove. After the magnetic metal block 432 is squeezed by the main handle 1 and the ring 3, it can push the slider 431 and the rubber block 6 to press against the inner wall of the limit groove, so as to facilitate and flexibly adjust the overall length of the sway blocking component 43, so that the sway blocking component 43 can adapt to the limit groove that is depressed and deformed after being squeezed, and reduce the possibility that the sway blocking component 43 is easily pushed out of the limit groove after the limit groove is squeezed and deformed.

[0028] In order to more conveniently control the magnetic metal block 432 to move to the outside of the limit groove, refer to Figure 4 , the top of the magnet block 433 is fixedly connected with an elastic sheet 7, and both sides of the elastic sheet 7 are fixedly connected with anti-slip strips 8. When in use, the magnetic metal block 432 is attracted and gradually approaches the magnet block 433, squeezing and bending the elastic sheet 7 to a certain extent. When the magnetic metal block 432 needs to be rotated to the outside of the limiting groove, it is only necessary to press the magnetic metal block 432 downward, and the magnetic metal block 432 continues to squeeze and bend the elastic sheet 7 to a greater extent, and then release the magnetic metal block 432. The elastic force of the elastic sheet 7 pushes the magnetic metal block 432 to overcome the attraction of the magnet block 433 and then pop up a distance. The pickers catch the area where the magnetic metal block 432 leaks to the outside of the limiting groove before the magnetic metal block 432 falls, and then bring The movable magnetic metal block 432 can continue to rotate toward the outside of the limiting groove. When the slider 431 is squeezed and damaged severely on the arc block 41 and needs to be replaced, the elastic sheet 7 can be held by hand to pull the magnet block 433 away from the slider 431. The anti-slip strip 8 increases the friction between the elastic sheet 7 and the hand, reducing the possibility of the hand slipping off the elastic sheet 7, until the magnet block 433 is pulled off the slider 431, so that the magnet block 433 can be recovered after the slider 431 is damaged, reducing the difficulty of controlling the magnetic metal block 432 to move to the outside of the limiting groove to achieve the limiting effect on the main handle 1. At the same time, it is also convenient to remove the magnet block 433 from the slider 431, so that the slider 431 can recover the magnet block 433 when it is squeezed and damaged severely.

[0029] Embodiment 3 In order to make the clamp knife stay on the coconut when it falls, to prevent the clamp knife from falling off the coconut, so that the ground staff can control the falling speed of the coconut through the clamp knife after pulling the rope, refer to Figure 1-Figure 6On the basis of the first embodiment, a rubber block 29 is installed on one side of the clamping plate 2, and a clamping assembly 10 for fixing the rubber block 29 is installed on the outer side of the clamping plate 2. The clamping assembly 10 includes a limit frame 101 sleeved on the outside of the clamping plate 2 and the rubber block 29. The width of the limit frame 101 close to the rubber block 29 is greater than the width of the side away from the rubber block 29. The side of the limit frame 101 close to the rubber block 29 is provided with a bolt 102 with one end movably passing through the limit frame 101. When in use, the rubber block 29 is attached to the outer side of the clamping knife of the clamping plate 2, and then the limit frame 101 is sleeved on the outside of the rubber block 29 and the clamping plate 2, and finally the bolt 102 is rotated to pass through the limit frame 101, so that the bolt The bolt 102 squeezes the rubber block 29 onto the clamp 2. When the coconut is picked, the clamp 2 gradually clamps off the coconut stalk. During this process, the rubber block 29 on the side of the clamp 2 gradually approaches the coconut stalk and is finally squeezed and deformed by the coconut stalk, so that the rubber block 29 is tightly attached to the coconut stalk. When the coconut is picked and falls from the coconut tree, the coconut stalk drags the clamp knife and falls at the same time. The rubber block 29 tightly attached to the coconut stalk reduces the possibility of the clamp knife falling off the coconut stalk, which can improve the firmness of the connection between the coconut and the clamp knife after the coconut is picked, reduce the possibility of the clamp knife falling off the coconut, and facilitate ground personnel to control the slow fall of the picked coconut when pulling the clamp knife through the traction rope 11.
