Description

Technical Field

[0001] The invention belongs to the technical field of seedling planting, and particularly relates to an unmanned aerial vehicle seedling planting device. Background Art

[0002] As people's living standards improve, environmental protection is receiving more and more attention. Planting various plants including trees is an important way to improve the environment. Existing planting techniques usually use artificial planting techniques and aircraft seeding techniques. Artificial planting requires a lot of labor, and it is very inconvenient for some mountainous areas or sandy lands with inconvenient transportation and sparse population.

[0003] Existing drone planting is suitable for planting seeds, but not for planting seedlings. When sowing plant seeds in sandy land, most of the seeds can only stay on the surface of the sand due to their light weight. After being exposed to high temperatures and severe water shortage, the survival rate of these seeds is greatly reduced. Under geological conditions such as slopes, the survival rate of seeds is even lower. At the same time, the seeds on the surface of the sand are inevitably eaten by birds and rodents.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Summary of the invention

[0005] The purpose of the present invention is to provide a drone seedling planting device that can plant seedlings quickly and accurately.

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0036] like Figures 1 to 16 As shown, a seedling planting device of a drone 1 according to the present invention comprises a drone 1 and a seedling planting mechanism mounted on the bottom of the drone 1, wherein the seedling planting mechanism comprises a plurality of launching components 2 for launching seedlings 4 and a carrying box 3 for carrying the launching components 2, a supporting foot 12 is provided at the bottom of the drone 1, and the supporting foot 12 is located on both sides of the carrying box 3; the launching component 2 comprises a launching tube 21, a mounting ring 22 slidably mounted on the launching tube 21, and a pneumatic mechanism 23 providing power to the mounting ring 22; a warhead 5 for wrapping the seedling 4 is also provided in the launching tube 21, and the roots of the seedlings 4 are covered with a soil ball, which is composed of a nutrient matrix required for the growth of the seedlings 4. The bullet 5 is clamped with the mounting ring 22, and the bullet 5 includes a first shell 51 and a second shell 52 that can be quickly separated. A connecting slider 511 is formed on the connecting surface of the first shell 51 and the second shell 52, and a connecting groove 521 that cooperates with the connecting slider 511 is formed on the connecting surface of the second shell 52 and the first shell 51; the front ends of the first shell 51 and the second shell 52 are both pointed, which is convenient for inserting into soil or sand. The ends of the first shell 51 and the second shell 52 are aligned, and the length of the first shell 51 is greater than that of the second shell 52. One end of the connecting groove 521 passes through the end of the second shell 52. When the bullet 5 penetrates into the soil or sand, since the length of the second shell 52 is smaller than that of the first shell 51, the first shell 51 will be inserted into the soil first. Under the action of inertia, the second shell 52 and the sapling 4 will continue to slide down. At this time, the connecting slider 511 on the first shell 51 will be disengaged from the connecting slide groove 521 of the second shell 52, and under the downward pressure of the sapling 4, the first shell 51 and the second shell 52 are separated, thereby completing the planting of the sapling 4.

[0037] In the present embodiment, in order to prevent the warhead 5 which has not been fired from sliding out of the carrying box 3, a connecting ring 221 connected to the warhead 5 is formed on the side of the mounting ring 22 close to the warhead 5, and a plurality of clamping posts 2211 are movably provided on the connecting ring 221, and the clamping posts 2211 are slidably connected to the connecting ring 221, and a resisting spring 2212 is sleeved on the clamping posts 2211; a resisting block 22111 which is in sliding contact with the launching tube 21 is formed on the top of the clamping posts 2211, and the top of the resisting block 22111 is arc-shaped and matches with the inner wall of the launching tube 21, a first clamping block 512 is formed at the end of the first cartridge case 51, and a second clamping block 522 is formed at the end of the second cartridge case 52, and the first clamping block 512 and the second clamping block 522 are both arc-shaped, and the outer wall of the first clamping block 512 and the outer wall of the second clamping block 522 are both arc-shaped. The outer wall of the second clamping block 522 fits with the inner wall of the connecting ring 221, and a first clamping groove 5121 clamped with the clamping column 2211 is formed on the outer wall of the first clamping block 512, and a second clamping groove 5221 clamped with the clamping column 2211 is formed on the outer wall of the second clamping block 522. When the warhead 5 is in the launching tube 21 and has not been launched, the supporting spring 2212 is compressed under the pressure of the inner wall of the launching tube 21, and the clamping column 2211 is clamped in the first clamping groove 5121 and the second clamping groove 5221 to prevent the warhead 5 from slipping out of the launching tube 21. When the warhead 5 is launched outward, in order to quickly disengage the warhead 5 from the mounting ring 22, a guide section 211 is formed on the inner wall of the launching tube 21 near the launching port, and the inner diameter of the guide section 211 gradually increases from the inside to the outside. When the mounting ring 22 moves to the guide section 211, the resisting block 22111 loses the restriction of the inner wall of the launching tube 21, and the clamping column 2211 can be pushed out under the action of the resisting spring 2212, so that the clamping column 2211 is separated from the first clamping groove 5121 and the second clamping groove 5221, so that the bullet 5 can be ejected smoothly. In addition, when installing the bullet 5, the sapling 4 is placed in the first cartridge case 51 and the second cartridge case 52 is clamped on the first cartridge case 51, and then pushed into the launching tube 21, so that the first clamping block 512 and the second clamping block 522 cooperate with the connecting ring 221, and in the process of pushing inward, the clamping column 2211 is re-inserted into the first clamping groove 5121 and the second clamping groove 5221 to fix the cartridge case.

[0038] In this embodiment, the outer wall of the launch tube 21 is provided with a guide tube 24 and an air storage tube 25; a guide through groove 241 is formed between the guide tube 24 and the launch tube 21, an air passage 251 is formed between the air storage tube 25 and the guide tube 24, the air storage tube 25 includes a high-pressure chamber 252 and a firing chamber 253, the air passage 251 is in the firing chamber 253, a partition 254 is provided between the high-pressure chamber 252 and the firing chamber 253, and a pressure relief hole 2541 is formed on the partition 254; the pneumatic mechanism 23 includes The piston block 231 is slidably arranged in the guide cylinder 24, the sealing block 232 is movably installed in the high-pressure chamber 252 and blocks the pressure relief hole 2541, the return spring 233 is connected to the end of the sealing block 232, the firing rod 234 is movably installed in the firing chamber 253, and the firing unit 235 drives the firing rod 234 to push the sealing block 232 away from the pressure relief hole 2541. The piston block 231 is provided with a plug-in column 2311 that passes through the guide groove 241 and is plugged into the mounting ring 22. The pneumatic mechanism 23 can be used to instantly release the high-pressure gas in the high-pressure chamber 252 to the guide cylinder 24 through the airway 251. The high pressure generated instantly pushes the piston block 231 forward, and the piston block 231 drives the mounting ring 22 to move, so that the warhead 5 is fired from the launch tube 21.

[0039] Specifically, in order to better install the firing rod 234, a mounting plate 2531 is provided in the firing chamber 253, and the firing rod 234 is slidably mounted on the mounting plate 2531. The mounting plate 2531 and the partition plate 254 are respectively located on both sides of the airway 251. The firing unit 235 includes a firing plate 2351 rotatably mounted on the inner wall of the firing chamber 253 and a firing generator 2352 driving the firing plate 2351 to rotate. The firing generator 2352 is fixedly mounted on the outer wall of the firing chamber 253; the firing rod 234 is supported by the mounting plate 2531. A driving plate 2341 is formed at one end near the firing plate 2351, and a plurality of hemispherical protrusions 23411 are formed on the side of the driving plate 2341 close to the firing plate 2351. A groove 23511 cooperating with the protrusion 23411 is formed on the firing plate 2351. There are three protrusions 23411 and three grooves 23511 respectively, all of which are arranged in a circular array. A limiting guide rod 25311 is formed on the mounting plate 2531, and a limiting guide hole 23412 cooperating with the limiting guide rod 25311 is formed on the driving plate 2341. When firing, the firing generator 2352 drives the firing plate 2351 to rotate quickly by 120°, so that the protrusion 23411 quickly withdraws from the groove 23511, and moves the firing rod 234 toward the sealing block 232, pushes the sealing block 232 away from the partition 254, opens the pressure relief hole 2541, and allows the high-pressure gas to enter the firing chamber 253 from the pressure relief hole 2541 and then enter the guide cylinder 24 from the airway 251, quickly pushes the piston block 231 forward, and fires the seedling 4. Under the action of the reset spring 233, the sealing block 232 can be quickly reset to re-block the pressure relief hole 2541; in addition, with the cooperation of the limiting guide rod 25311 and the limiting guide hole 23412, the driving plate 2341 and the firing plate 2351 can be prevented from rotating at the same time, so that the firing rod 234 can move forward smoothly.

[0040] In this embodiment, in order to smoothly launch the warhead 5, the guide groove 241 extends to the guide section 211, so that the mounting ring 22 can smoothly enter the guide section 211, so that the clamping column 2211 can withdraw from the first clamping groove 5121 and the second clamping groove 5221, and the warhead 5 can be smoothly launched; a plurality of exhaust holes 242 are formed at one end of the guide tube 24 close to the launching tube 21, and when the piston block 231 is moving rapidly, the internal air can be discharged to reduce the resistance at the front end of the piston block 231, and in addition, a buffer rubber pad 2312 is formed at the front end of the piston block 231, and the end of the buffer rubber pad 2312 is hemispherical, and a sealing plate 2313 is formed at the end of the piston block 231 to seal the guide groove 241. The buffer rubber pad 2312 can be used to buffer and slow down the piston block 231, thereby increasing the service life of the piston block 231. The sealing plate 2313 can be used to prevent the high-pressure gas from leaking out of the guide groove 241, resulting in insufficient power of the piston block 231 and an inability to launch the warhead 5. It should be noted that the seal between the sealing plate 2313 and the guide groove 241 is not completely sealed. There is a small gap between the sealing plate 2313 and the guide groove 241, so that when the new warhead 5 is installed back, the internal air can be quickly discharged, and the warhead 5 can be smoothly pushed into the launch tube 21. In addition, a magnetic attraction portion is provided at the end of the sealing plate 2313, which can be adsorbed with the inner wall on the side away from the exhaust hole 242, but the magnetic force is much smaller than the impact force of the high-pressure gas. The magnetic attraction can prevent the entire mounting ring 22 from detaching from the launch tube 21 when not launched.

[0041] In this embodiment, in order to improve the stability of the warhead 5 when it is launched, there are two groups of guide cylinders 24, and the two groups of guide cylinders 24 are respectively located on both sides of the lower part of the launch cylinder 21, and the air storage cylinder 25 is located between the two guide cylinders 24, and there are two air passages 251, which are respectively connected to the two guide cylinders 24. The pistons in the two groups of guide cylinders 24 are connected to the mounting ring 22 respectively, so that the mounting ring 22 can be more stable when moving. In addition, a high-pressure gas nozzle is provided at the tail of the air storage cylinder 25, and the high-pressure gas nozzle can be used to pressurize the high-pressure chamber 252.

[0042] In this embodiment, a plurality of launching assemblies 2 are arranged in a matrix on a carrying box 3, a plurality of mounting cavities are formed on the carrying box 3, and a launching port of a launching tube 21 is located outside the carrying box 3. The carrying box 3 also includes a connecting frame 31 connected to the UAV 1. The connecting frame 31 is in a "U" shape as a whole, and the connecting frame 31 is rotatably connected to both sides of the carrying box 3. Specifically, a motor can be installed to drive the carrying box 3 to rotate, so as to adjust the launching angle; a connecting seat 11 is formed at the bottom of the UAV 1, and a connecting groove 111 is formed on the connecting seat 11. A connecting block 311 which is plugged into the connecting groove 111 is provided at the top of the connecting frame 31. Both the connecting groove 111 and the connecting block 311 are "T"-shaped blocks. Limiting plug-in rods 6 are also movably provided on both sides of the connecting seat 11. A compression spring 7 is also provided at the inner end of the limiting plug-in rod 6. A limiting plug-in hole 3111 for inserting the limiting plug-in rod 6 is formed on the connecting block 311. A pull rod 61 is provided at one end of the limiting plug-in rod 6. A pull head 611 is provided at the end of the pull rod 61. The compression spring 7 is sleeved on the pull rod 61. A guide surface 3112 is formed at the front end of the connecting block 311. When installing the carrying box 3, it is only necessary to push the connecting head into the connecting groove 111, and the guide surface 3112 can be used to automatically retract the limiting plug rod 6 until it is aligned with the limiting plug hole 3111. Under the action of the compression spring 7, the limiting plug rod 6 is pushed into the limiting plug hole 3111 to complete the installation. When disassembly is required, it is only necessary to pull the limiting connecting rod outward to disengage it from the limiting plug hole 3111, and the connecting block 311 can be pulled out of the connecting groove 111. The overall operation is relatively convenient.

[0043] The method of using the present invention is as follows: first, place the sapling 4 in the warhead 5, and install the warhead 5 into the launching tube 21, then remotely control the drone 1 to take off above the destination, about 3-8 meters from the ground, and then successively launch the warhead 5 into the soil, the first shell 51 will touch the ground first and be inserted into the soil, at the same time, under the action of inertia, the second shell 52 and the sapling 4 will continue to slide downward, and under the squeezing of the sapling 4, the second shell 52 is separated from the first shell 51, thereby realizing the planting of the sapling 4, and the forestry maintenance personnel can pick up the first shell 51 and the second shell 52 in subsequent inspections, and can re-straighten the sapling 4 that has not been inserted properly.
