[0006] Preferably, a limiting groove is provided on one side of the blade, a counterweight component movably extending into the limiting groove is provided on one side of the blade, and positioning components for fixing the counterweight component on the blade are installed at both ends of the counterweight component.

[0007] Preferably, the counterweight assembly includes a plurality of counterweight blocks slidably connected to the blade, both sides of the counterweight blocks away from the blade are inclined, one side of the counterweight block is provided with a notch adapted to the blade, and a sliding block is provided in the notch of the counterweight block with one end movably extending into the limit groove.

[0008] Preferably, the positioning assembly includes an elastic frame installed at both ends of the counterweight assembly, the elastic frame is fixedly connected to the slider, the elastic frame is slidably connected to the inner wall of the limiting groove, a long groove penetrating the elastic frame is opened on one side of the elastic frame, a bolt movably penetrating the long groove is provided on one side of the elastic frame, one end of the bolt movably extends to the interior of the slider, and a rubber strip is fixedly connected to the bottom middle area of ​​the elastic frame.

[0009] Preferably, the width of the blade is 1-2 cm, the length of the handle is 16 cm, and the overall length of the handle and the blade is 44 cm.

[0010] The present invention also provides a packaging box for a special tropical high-plant coconut picking knife, which includes a bottom box, one side of the bottom box is rotatably connected to an upper half box and a lower half box respectively covering half of its area, and opposite sides of the lower half box and the bottom box are each provided with an accommodating cavity for accommodating the handle, and a blade trimming component is installed inside the upper half box for cleaning the surface of the blade when the blade moves along the length direction of the bottom box and pressing the blade to fix it.

[0011] Preferably, the blade arrangement assembly includes a square frame which is movably extended to the interior of the upper half box, a slide groove corresponding to the square frame is provided on one side of the upper half box, a spring is fixedly connected between the inner wall of the square frame and the slide groove, two limiting grooves are provided in the lower area on one side of the square frame close to the bottom box, and a sponge strip extending to the outside of the square frame is provided inside the limiting groove.

[0012] Preferably, a hanging ring is installed on the side of the upper half box and the lower half box away from the bottom box, and a fiber rope corresponding to the hanging ring is fixedly connected to one side of the bottom box.

[0013] Compared with the prior art, the present invention provides a special picking knife for tropical high-growing coconuts and a packaging box thereof, which has the following beneficial effects:

[0014] 1. By setting a smaller connecting end, middle blade and front blade, the width of the blade is reduced, the style of the coconut knife is improved, and the weight of the tool is reduced to make coconut picking more labor-saving. The front one-fifth of the tool is used to cut the fruit handle, which reduces the pressure on the back of the hand, relieves hand fatigue when picking coconuts, improves work efficiency, and reduces the risk of accidents in high temperature and high humidity environments.

[0015] 2. By setting the front part of the knife, the picking tool mainly uses the front part of the knife which occupies one fifth of the length of the blade. Only one fifth of the length of the knife needs to be sharpened and polished. Each sharpening is very convenient, which reduces the difficulty of maintenance of the picking tool.

[0016] 3. By setting up the counterweight assembly, the upper half of the top middle blade and the front of the knife can be supported by the bottom near one end of the handle, which not only increases the support point of the front of the knife for cutting the fruit handle, but also moves the support point toward the handle for a distance, thereby strengthening the front of the knife and reducing the possibility of the picking knife breaking when cutting the fruit handle. It also changes the center of gravity position of the blade, making the center of gravity of the blade closer to the front of the knife, which is more conducive to the accuracy and flexibility of cutting the handle.

[0017] 4. By setting up the counterweight assembly, the counterweight block is moved to the end of the blade close to the handle, so that the center of gravity of the blade is close to the middle blade part and the connecting end in the middle of the blade, which is more conducive to the strong chopping of the blade. When the coconut stalk is harder, the center of gravity of the blade can be flexibly adjusted to the lower middle area, which is more conducive to chopping the stalk and is suitable for cutting the harder stalk of coconut.

[0018] 5. By setting the positioning component, when the counterweight component is moved, the elastic frame is driven to scrape the limit groove, so as to clean up the impurities attached to the limit groove and prevent the impurities from falling into the gap between the counterweight block and the limit groove to hinder the movement of the counterweight component.

[0019] 6. The blade finishing component can be used to clean the juice and coconut palm dust on the surface of the coconut picking tool when the coconut picking tool is pushed into the packaging box, thereby preventing the juice and coconut palm dust from adhering to the surface of the picking tool, improving the neatness of the tool and the packaging box, and preventing the juice and coconut palm dust from solidifying on the surface of the tool and reducing its sharpness.

[0020] 7. The handle and blade, plus the length of the staff's arm, can reach 1.2m, which can cover most areas within the radius of the coconut tree, making it convenient for staff to pick coconuts far from the trunk. The wooden handle does not hurt the hand compared to the rubber material. The blade is longer than the existing blade, which can increase the distance between the staff and the picking position when picking coconuts, and reduce the possibility of brown ash falling on the staff when picking coconuts.

DETAILED DESCRIPTION

[0030] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Embodiment 1

[0032] In order to solve the problem that coconut picking knives are heavy, it is more laborious to pick coconuts, and the pressure on the back of the hand is greater. Figure 1As one embodiment of the present invention, a special picking tool for tropical high-growing coconuts is proposed, comprising a blade 1 and a handle 2, the blade 1 comprising a connecting end 101 fixedly connected to the handle 2, the end of the connecting end 101 away from the handle 2 is fixedly connected to a middle blade portion 102, the end of the middle blade portion 102 away from the connecting end 101 is fixedly connected to a front blade portion 103, the connecting end 101, the middle blade portion 102 and the front blade portion 103 are an integrated structure, the length ratio of the front blade portion 103 to the blade 1 is 1:5, the maximum width of the blade 1 is less than the width of the handle 2, the width of the front blade portion 103 is less than the width of the connecting end 101 and the middle blade portion 102, the width of the handle 2 gradually increases from the middle to both ends, since the width of the blade 1 is less than the width of the handle 2, the blade width of the improved picking tool is only 1-2 cm, and now for The width of a common coconut picking tool is 4-5 cm, and the width of the blade 1 is reduced. The blade 1 of the picking tool is made of metal and has a relatively large weight, while the handle 2 is made of wood and has a relatively small weight. The purpose of reducing the overall weight of the picking tool is achieved by reducing the width of the blade 1. The improved blade 1 mainly relies on the front portion 103 of the blade 1, which occupies one-fifth of the length of the blade 1, when picking coconuts. Compared with the common picking tools, the blade 102 is used for cutting, which is more conducive to the user's force, reduces the width of the blade, improves the style of the coconut knife, and can make coconut picking more labor-saving by reducing the weight of the tool. In addition, the front one-fifth of the knife is used to cut the fruit handle, which reduces the pressure on the back of the hand, can relieve hand fatigue when picking coconuts, improve work efficiency, and reduce the risk of accidents when working in high temperature and high humidity environments.

[0033] 800 trees can be harvested. This type of cutter is particularly suitable for coconut trees that produce fruit in clusters around the trunk (each cluster contains 3-15 large fruits, 20-25 small fruits, and weighs about 130 catties). Coconut trees produce fruit around the trunk, and some have 2 layers around the trunk (up to 6 clusters). Our operation requires the cutter to be efficient, labor-saving, and easy to operate. This must be considered. Especially for the highly fibrous calcified main fruit stalk, it is more difficult.

[0034] The improved front portion 103 of the knife has a greater degree of curvature, which can save more effort when cutting the coconut stalk, thereby reducing the physical exertion of workers when picking coconuts, making it less likely to sweat, and being suitable for use in high temperature and high humidity environments. At the same time, the front portion 103 of the knife with a greater curvature and reduced width is suitable for inserting into the gaps between a bunch of coconuts, making it convenient to cut a single coconut from a bunch of coconuts, so that the improved picking tool is not only suitable for cutting a whole bunch of coconuts when picking from a coconut tree for the first time, but also suitable for cutting a single coconut from the whole bunch of coconuts when picking for the second time.

[0035] The wooden handle 2 is slightly thicker in the middle and slightly thinner at both ends, suitable for holding and easy operation. The handle 2 is 16 cm long, and the overall length of the handle 2 and the blade 1 is 44 cm, which can be satisfied with single-handed or double-handed operation on the tree, cutting on the ground, or standing in front of an operating table. The length of the handle 2, the blade 1 and the staff's arm can reach 1.2 m, which can cover most areas within the radius of the coconut tree, making it convenient for the staff to pick coconuts far from the trunk. Moreover, the wooden handle 2 does not hurt the hand compared to the rubber material. The blade 1 is longer than the existing blade, which can increase the distance between the staff and the picking position during picking, and reduce the possibility of brown ash falling on the staff when picking coconuts.

[0036] The picking tool mainly uses the front part 103 of the blade 1, which occupies one fifth of the length of the blade 1. Only one fifth of the length of the blade needs to be sharpened and polished. Each sharpening is very convenient, which reduces the difficulty of maintenance of the picking tool. Generally, the tool can be used for 1-2 months after being sharpened once.

[0037] Embodiment 2

[0038] Since the width of the blade 1 is reduced, in order to maintain the strength of the blade 1, refer to Figure 2-Figure 5 On the basis of the first embodiment, a limiting groove is provided on one side of the blade 1, and a counterweight component 3 is provided on one side of the blade 1 and movably extends into the limiting groove. Positioning components 4 for fixing the counterweight component 3 on the blade 1 are installed at both ends. The counterweight component 3 includes a plurality of counterweight blocks 31 slidably connected to the blade 1. Both sides of the counterweight blocks 31 away from the blade 1 are inclined surfaces. A notch is provided on one side of the counterweight block 31 that matches the blade 1. A slider 32 with one end movably extending into the limiting groove is provided in the notch of the counterweight block 31. When in use, the counterweight component 3 can be moved along the limiting groove to the end of the blade 1 close to the handle 2, or to the end away from the handle 2. The specific differences are as follows:

[0039] When it is necessary to strengthen the strength of the front part 103 of the knife, the picker moves the counterweight assembly 3 along the blade 1, moves the counterweight blocks 31 to the end of the blade 1 away from the handle 2, and then uses the positioning assembly 4 to fix the counterweight assembly 3 to the blade 1. The overall length of the counterweight assembly 3 is relatively long, and can rely on the bottom near the end of the handle 2 to support the upper half of the top middle blade 102 and the front part 103 of the knife. Not only does it increase the support points of the front part 103 of the knife for cutting the fruit handle, but it also moves the support points a certain distance toward the handle 2, thereby strengthening the front part 103 of the knife, which can reduce the possibility of the picking tool breaking when cutting the fruit handle, and changes the center of gravity position of the blade 1, so that the center of gravity of the blade is closer to the front part 103 of the knife, which is more conducive to the accuracy and flexibility of cutting the handle.

[0040] When the coconut stalk that needs to be cut is highly fibrous and extremely hard, the picker moves the counterweight assembly 3 along the blade 1 and moves the counterweight block 31 to the end of the blade 1 close to the handle 2, so that the center of gravity of the blade 1 is close to the middle blade portion 102 and the connecting end 101 in the middle of the blade 1, which is more conducive to the strong chopping of the blade 1. When the coconut stalk is harder, the center of gravity of the blade 1 can be flexibly adjusted to the lower middle area, which is more conducive to chopping the stalk and is suitable for occasions of cutting harder coconut stalks.

[0041] In order to fix the counterweight assembly 3 after it has been moved, refer to Figure 4 and Figure 5 The positioning assembly 4 includes an elastic frame 41 installed at both ends of the counterweight assembly 3, the elastic frame 41 is fixedly connected to the slider 32, the elastic frame 41 is slidably connected to the inner wall of the limiting groove, a long groove penetrating the elastic frame 41 is provided on one side of the elastic frame 41, a bolt 42 movably penetrating the long groove is provided on one side of the elastic frame 41, one end of the bolt 42 movably extends to the inside of the slider 32, and a rubber strip 43 is fixedly connected to the middle area of ​​the bottom of the elastic frame 41. When in use, the elastic frame 41 is away from the inner wall of the limiting groove under its own elastic action, and the elastic frame 41 does not contact the limiting groove, so that the counterweight can be flexibly pushed. The component 3 slides along the blade 1. When the counterweight component 3 needs to be fixed, the bolt 42 is turned to push the elastic frame 41 gradually close to the counterweight block 31. The bottom of the elastic frame 41 contacts the inner wall of the limit groove and is squeezed and bent. In the first stage, the end of the elastic frame 41 away from the counterweight block 31 contacts the limit groove. At this time, the counterweight block 31 can still drive the elastic frame 41 to move along the limit groove. In this stage, when the counterweight component 3 is moved, the elastic frame 41 is driven to scrape the limit groove, which can clean up impurities attached to the limit groove and prevent the impurities from falling into the gap between the counterweight block 31 and the limit groove to hinder the movement of the counterweight component 3.

[0042] In the second stage, the bolt 42 pushes the elastic frame 41 to squeeze the inner wall of the limiting groove, causing the elastic frame 41 to bend to a greater extent until the middle area of ​​the bottom of the elastic frame 41 contacts the inner wall of the limiting groove. At this time, the friction between the rubber strip 43 in the middle area of ​​the bottom of the elastic frame 41 and the limiting groove is relatively large, which will hinder the elastic frame 41 from moving along the limiting groove, thereby achieving the fixation of the counterweight block 31 and the elastic frame 41, making it convenient to fix the counterweight assembly 3 after it moves to the specified position, thereby achieving the purpose of flexibly adjusting the center of gravity of the blade 1.

[0043] Embodiment 3

[0044] In order to protect the coconut picking knives and facilitate the pickers to carry them and climb the coconut trees, refer to Figure 6-Figure 7On the basis of the first embodiment, a packaging box for a special tropical high-plant coconut picking knife is provided, the packaging box comprising a bottom box 5, one side of the bottom box 5 is rotatably connected with an upper half box 6 and a lower half box 7 covering half of its area respectively, and a receiving cavity 8 for accommodating the handle 2 is provided on the opposite side of the lower half box 7 and the bottom box 5, and a blade tidying component 9 is installed inside the upper half box 6 to clean the surface of the blade 1 when it moves along the length direction of the bottom box 5 and press the blade 1 to fix it, the blade tidying component 9 comprises a square frame 91 movably extending to the inside of the upper half box 6, one side of the upper half box 6 is provided with a slide groove corresponding to the square frame 91, a spring 92 is fixedly connected between the inner wall of the square frame 91 and the slide groove, and the square frame 9 Two limiting grooves are provided in the lower area of ​​one side close to the bottom box 5, and a sponge strip 93 extending to the outside of the square frame 91 is provided inside the limiting groove. A hanging ring 10 is installed on the side of the upper half box 6 and the lower half box 7 away from the bottom box 5, and a fiber rope 11 corresponding to the hanging ring 10 is fixedly connected to one side of the bottom box 5. When in use, the coconut picking tool is placed on the bottom box 5, the handle 2 is placed in the accommodating cavity 8, and then the upper half box 6 and the lower half box 7 are covered on the bottom box 5, and the fiber rope 11 is passed through the hanging ring 10 and then fastened, so as to provide a packaging box for accommodating the coconut picking tool, which is convenient for the pickers to carry the tool after wrapping it, and can reduce the possibility of the pickers being scratched by the tool when carrying the picking tool to climb the coconut tree when they are tired.

[0045] When the picking knife cuts the coconut stalk, it is easy to adhere to the juice and coconut dust on the surface, which will easily dirty the box after being placed inside the box. In addition, the juice and coconut dust stuck on the knife will solidify on the surface of the knife and affect the sharpness of the knife. In order to clean the juice and coconut dust on the surface of the knife, refer to Figure 6 and Figure 7 First, buckle the upper half box 6 on the bottom box 5, then use the fiber rope 11 to pass through the hanging ring 10 and fasten it to fix the upper half box 6 and the bottom box 5. When you need to put the knife into the packaging box, you only need to open the lower half box 7, and then insert the blade 1 from the bottom of the upper half box 6 between the upper half box 6 and the bottom box 5. The spring 92 pushes the square frame 91 to press the blade 1 on the bottom box 5. When the knife enters the packaging box, it is rubbed by the sponge strip 93, and the juice and coconut palm dust on its surface are wiped off by the sponge strip 93. When the blade 1 completely enters the packaging box, it is no longer pushed upward from the bottom of the upper half box 6. The tool is moved. At this time, the tool is pressed on the bottom box 5 by the square frame 91 to be fixed, and then the debris that falls from the blade into the bottom box 5 is shaken off until the tool needs to be removed to continue cutting the coconut stalk. Then the handle 2 is pulled upward until the blade 1 is separated from the upper box 6. The process of pushing the coconut picking tool into the packaging box can be used to clean the juice and coconut palm dust on the surface of the tool to prevent the juice and coconut palm dust from adhering to the surface of the picking tool, thereby improving the cleanliness of the tool and the packaging box and preventing the juice and coconut palm dust from solidifying on the surface of the tool to reduce its sharpness.
