Description

Technical Field

[0001] This invention belongs to the field of ecological restoration technology, and specifically relates to a device for ecological restoration of sandy land. Background Technology

[0002] Land desertification is one of the major ecological problems facing the world today. Afforestation for desert ecological restoration is an effective means to curb desertification and improve the ecological environment. However, traditional manual transplanting methods for large-scale tree planting in sandy environments suffer from high labor intensity, low efficiency, high planting costs, and worker fatigue, making them unsuitable for the needs of large-scale, rapid ecological restoration.

[0003] To address the aforementioned problems, some semi-automatic or automatic tree planting machinery has emerged on the market. These machines typically possess functions such as drilling holes, placing seedlings, and covering with soil. However, existing sand planting devices still have many shortcomings in practical applications: First, in the drilling stage, sandy soil is loose and highly fluid, and conventional drill bits easily cause the pit walls to collapse after drilling, making it difficult to form a regular and stable planting pit. If the pit has partially collapsed before placing the seedlings, it can lead to inaccurate planting depth or tilting of the seedlings, affecting their survival rate. In addition, existing drill bits have a single function, only capable of drilling holes; subsequent soil covering often requires additional mechanisms, making the equipment structure complex. In view of this, the inventors conducted in-depth research on the aforementioned shortcomings of the prior art, resulting in this invention. Summary of the Invention

[0004] The purpose of this invention is to provide a sandy land ecological restoration device that simplifies the equipment structure and improves the efficiency of seedling transplantation.

[0005] A sandy land ecological restoration device includes a transport vehicle, a pit-opening mechanism mounted on the transport vehicle, and a seedling storage mechanism. The transport vehicle includes a base plate and moving parts, and also includes a conveying mechanism for transporting seedlings from the seedling storage mechanism to the pit-opening mechanism. The pit-opening mechanism includes a soil-drilling component, a drive component for rotating the soil-drilling component, and a mounting plate. The mounting plate is movably mounted on the base plate, and the base plate has a through groove for the mounting plate to pass through. A first mounting frame for mounting the mounting plate is also provided on the base plate. A telescopic cylinder for raising and lowering the mounting plate is fixedly mounted on the first mounting frame. The mounting plate is also provided with a guide rod that slides with the first mounting frame; the soil drilling assembly includes a rotating cylinder rotatably mounted on the mounting plate and a conical drill bit mounted at the bottom of the rotating cylinder. The conical drill bit is hollow and consists of at least two conical segments. Multiple conical segments are arranged in a circular array around the axis of the conical drill bit. Spiral blades are formed on the outer wall of the conical drill bit. The bottom of the rotating cylinder is provided with a mounting ring for mounting the conical segments. The conical segments are movably mounted on the mounting ring. The bottom of the mounting ring is provided with multiple first mounting grooves. The top of the conical segments is provided with first mounting sliders that cooperate with the first mounting grooves. Multiple micro cylinders that drive the conical segments to move along the first mounting grooves are fixedly mounted on the outer wall of the mounting ring. The conveying mechanism feeds the seedlings from the top of the rotating cylinder.

[0006] Furthermore, each of the first mounting grooves is provided with a second mounting groove on both sides, and the conical segment is also provided with a second mounting slider that cooperates with the second mounting groove; a return spring is also installed in the second mounting groove. The cooperation between the second mounting groove and the second mounting slider can make the conical segment move smoothly.

[0007] Furthermore, the drive assembly includes a first motor, a first pulley fixedly mounted on the output shaft of the first motor, a second pulley fixedly mounted on the rotating cylinder, and a transmission belt mounted on the first pulley and the second pulley.

[0008] Furthermore, the conveying mechanism includes a first conveyor belt and a spiral conveying roller. The first conveyor belt is driven by a second motor, and the spiral conveying roller is driven by a third motor. The conveying direction of the spiral conveying roller is the same as the conveying speed of the first conveyor belt, and the spiral conveying roller is located above the first conveyor belt. The conveying length of the first conveyor belt is less than the length of the spiral conveying roller. The base plate is also provided with a second mounting bracket for mounting the first conveyor belt and a third mounting bracket for mounting the spiral conveying roller. By simultaneously conveying the seedlings using the first conveyor belt and the spiral conveying roller, the seedlings can remain stable during the conveying process.

[0009] Furthermore, a guide plate is inclinedly provided on the base plate, with the higher end of the guide plate located below the output end of the first conveyor belt and the lower end located above the edge of the through groove. The guide plate allows seedlings to be precisely fed from the top of the rotating drum.

[0010] Furthermore, the seedling storage mechanism includes a seedling storage box and a second conveyor belt for transporting seedlings from the seedling storage box to the conveying mechanism; the seedling storage box has an outlet on the side near the conveying mechanism; the base plate is also provided with a fourth mounting frame for mounting the second conveyor belt, the output end of the second conveyor belt is located above the first conveyor belt, and the conveying direction of the second conveyor belt is perpendicular to the conveying direction of the first conveyor belt in the horizontal plane; the fourth mounting frame is also provided with a fourth motor for driving the second conveyor belt to rotate; the seedling storage box has multiple seedling storage channels. The second conveyor belt can be used to transport seedlings from the seedling storage box to the conveying mechanism.

[0011] Furthermore, a retaining assembly is installed within the seedling storage channel. This retaining assembly includes a transmission belt and a mounting frame. The transmission belt has several partitions, and the mounting frame houses two transmission wheels, with the transmission belt fitted over these wheels. A mounting block is formed within the seedling storage channel, and the mounting frame is rotatably mounted on this block. A gear is fixedly mounted on a shaft at one end of the mounting frame, positioned on the side of the seedling storage box away from the conveying mechanism. A gear rack, meshing with the gear, is slidably mounted on the outer wall of the seedling storage box on the side away from the conveying mechanism, and a handle is provided on the outer side of one end of the gear rack. This retaining assembly ensures the stability of the seedlings during their transfer to the conveying mechanism.

[0012] Furthermore, a partition is provided between adjacent seedling storage channels, and the partition is installed on one side of the mounting block. The partition is used to prevent the retaining components from interfering with the seedlings in adjacent seedling storage channels.

[0013] Furthermore, there are two sets of seedling storage mechanisms, located on either side of the conveying mechanism. Having two sets of seedling storage mechanisms increases the number of seedlings transplanted per round and reduces the frequency of transport vehicle movement.

[0014] With the above structure, the sandy land ecological restoration device of this invention, compared with the prior art, uses a pit-opening mechanism, a conveying mechanism, and a seedling storage mechanism mounted on a transport vehicle. The conveying mechanism transports the seedlings from the seedling storage mechanism to the pit-opening mechanism. In addition, the soil-drilling component of the pit-opening mechanism includes a rotating cylinder and a conical drill bit. The conical drill bit is a hollow pile and is connected to the rotating cylinder. The conical drill bit is composed of multiple conical segments arranged in a ring array. The multiple conical segments can move on the mounting ring. During the pit-drilling process, the conical segments move closer to each other, and the sand is turned outward by the spiral blades. After the pit is drilled, the multiple conical segments are pushed outward by a micro cylinder, and the seedlings are put into the pit from the top of the rotating cylinder by the conveying mechanism. Then, the rotating cylinder is driven to reverse and slowly move upward under the action of the mounting plate. Under the action of the spiral blades, the sand on the pit wall can collapse and fill the roots of the seedlings with soil. In the entire transplanting process, there is no need to set up an additional soil-filling structure, which simplifies the equipment structure, saves costs, and improves the efficiency of transplanting.

[0030] like Figures 1-12As shown, this invention relates to a sandy land ecological restoration device, comprising a transport vehicle 1, a pit-opening mechanism 2 mounted on the transport vehicle 1, and a seedling storage mechanism 3. The transport vehicle 1 includes a base plate 11 and a moving component 12, which can be tracked for easy movement on sandy land. The movement of the entire transport vehicle 1 can be controlled remotely. The transport vehicle 1 is also equipped with a conveying mechanism 4 for transporting seedlings from the seedling storage mechanism 3 to the pit-opening mechanism 2. Specifically, the pit-opening mechanism 2 includes a soil-drilling component 21, a drive component 22 for rotating the soil-drilling component 21, and a mounting mechanism 3. Mounting plate 23 is movably mounted on base plate 11. Base plate 11 has a through groove 111 for mounting plate 23 to pass through. Base plate 11 also has a first mounting bracket 112 for mounting plate 23. A telescopic cylinder 5, which drives the mounting plate 23 to rise and fall, is fixedly mounted on the first mounting bracket 112. The telescopic cylinder 5 can be a hydraulic cylinder or a pneumatic cylinder. The cylinder body of the telescopic cylinder 5 is fixedly mounted on the first mounting bracket 112, and the piston rod of the telescopic cylinder 5 is fixedly connected to the top of mounting plate 23. Two telescopic cylinders 5 are provided, respectively connected to both sides of the middle of mounting plate 23. The mounting plate 23 is also provided with guide rods 231 that slide with the first mounting bracket 112. There are four guide rods 231, which are located at the four corners of the mounting plate 23. During drilling, the drilling assembly 21 can be raised and lowered by the telescopic cylinder 5. The drive assembly 22 includes a first motor 221, a first pulley 222 fixedly sleeved on the output shaft of the first motor 221, a second pulley 223 fixedly sleeved on the rotating cylinder 211, and a transmission belt 224 sleeved on the first pulley 222 and the second pulley 223. The mounting plate 23 is also provided with A support frame for mounting the first motor 221, with the entire drive assembly 22 positioned above the mounting plate 23; the drilling assembly 21 includes a rotating cylinder 211 rotatably mounted on the mounting plate 23 and a conical drill bit 212 mounted at the bottom of the rotating cylinder 211. The conical drill bit 212 is hollow, and the top of the rotating cylinder 211 is open. The conical drill bit 212 is composed of at least two conical lobes 2121, and multiple conical lobes 2121 are arranged in a circular array around the axis of the conical drill bit 212. Spiral blades 2122 are formed on the outer wall of the conical drill bit 212.The bottom of the rotating cylinder 211 is provided with a mounting ring 2111 for mounting the conical segments 2121. The conical segments 2121 are movably mounted on the mounting ring 2111. The bottom of the mounting ring 2111 is provided with multiple first mounting grooves 21111. The top of the conical segment 2121 is provided with a first mounting slider 21211 that mates with the first mounting groove 21111. Multiple micro cylinders 6 are fixedly installed on the outer wall of the mounting ring 2111, each driving the conical segment 2121 to move along the first mounting groove 21111. The micro cylinders 6 can drive the multiple conical segments 2121 to move away from or closer to each other. During drilling, the multiple conical segments 2121 are closed together to form a complete cone, facilitating drilling. After drilling, the micro cylinders 6 can drive the multiple conical segments 2121 to spread outwards, and the conveying mechanism 4 feeds the sapling from the top of the rotating cylinder 211. Then, the driving assembly 22 drives the rotating cylinder 211 to reverse direction. At this time, under the action of the spiral blades 2122, the sand on the pit wall collapses into the pit, perfectly filling the sapling with soil.

[0031] In this embodiment, to make the conical segments 2121 move more smoothly, a second mounting groove 21112 is provided on both sides of each of the first mounting grooves 21111. The conical segments 2121 are also provided with a second mounting slider 21212 that cooperates with the second mounting grooves 21112. The first groove and the second groove are T-shaped grooves, and the first slider and the second slider are also T-shaped blocks. A return spring 8 is also installed in the second mounting groove 21112. The return spring 8 can also make the conical segments 2121 close more tightly.

[0032] In this embodiment, to prevent the seedlings from tipping over when the conveying mechanism 4 is conveying the seedlings, the conveying mechanism 4 can be configured as an upper and lower layer structure. Specifically, the conveying mechanism 4 includes a first conveyor belt 41 and a spiral conveying roller 42. The first conveyor belt 41 is driven by a second motor 43, and the spiral conveying roller 42 is driven by a third motor 44. The conveying direction of the spiral conveying roller 42 is consistent with the conveying speed of the first conveyor belt 41, and the spiral conveying roller 42 is located above the first conveyor belt 41. The conveying length of the first conveyor belt 41 is less than the length of the spiral conveying roller 42. The base plate 11 is also provided with a second mounting bracket 113 for mounting the first conveyor belt 41 and a third mounting bracket 114 for mounting the spiral conveying roller 42. During transport, the sapling's root ball rests on the first conveyor belt 41, while the sapling's trunk rests on the spiral conveyor roller 42. The synchronous transport of the spiral conveyor roller 42 and the first conveyor belt 41 ensures the sapling's stability during transport. Additionally, a guide plate 115 is inclinedly mounted on the base plate 11. The higher end of the guide plate 115 is located below the output end of the first conveyor belt 41, and the lower end is located above the edge of the through groove 111. The guide plate 115 is arc-shaped, allowing the sapling to fall precisely from the top of the rotating drum 211 into the pit after it falls from the output end of the first conveyor belt 41.

[0033] In this embodiment, the seedling storage mechanism 3 includes a seedling storage box 31 and a second conveyor belt 32 for conveying seedlings from the seedling storage box 31 to the conveying mechanism 4. There are two sets of seedling storage mechanisms 3, located on opposite sides of the conveying mechanism 4. The seedling storage box 31 has an outlet on the side closest to the conveying mechanism 4. A fourth mounting frame 116 for mounting the second conveyor belt 32 is also provided on the base plate 11. The output end of the second conveyor belt 32 is located above the first conveyor belt 41, and the conveying direction of the second conveyor belt 32 is perpendicular to the conveying direction of the first conveyor belt 41 on the horizontal plane. A fourth motor 321 for driving the second conveyor belt 32 to rotate is also provided on the fourth mounting frame 116. The seedling storage box 31 has multiple seedling storage channels 311, and a holding assembly 7 is installed in each seedling storage channel 311. The holding assembly 7 includes a transmission belt 71 and a mounting frame 72. The storage box 311 is equipped with several partitions 711 to keep the seedlings stable. Two drive wheels 721 are located inside the mounting frame 72, and a drive belt 71 is fitted onto the two drive wheels 721. A mounting block 312 is formed within the seedling storage channel 311, and the mounting frame 72 is rotatably mounted on the mounting block 312. A gear 722 is fixedly mounted on a shaft at one end of the mounting frame 72, and the gear 722 is located on the side of the seedling storage box 31 away from the conveying mechanism 4. A gear rack 33, meshing with the gear 722, is slidably mounted on the outer wall of the seedling storage box 31 on the side away from the conveying mechanism 4. A handle 331 is located on the outer side of one end of the gear rack 33. A partition 313 is also provided between adjacent seedling storage channels 311, and the partition is installed on one side of the mounting block 312. Multiple saplings are arranged in a matrix in the seedling storage box 31. The second conveyor belt 32 transports the saplings from the seedling storage box 31 row by row to the conveying mechanism 4. The seedlings in one seedling storage box 31 are transported only after the seedlings in the other seedling storage box 31 have been transplanted. During the transportation process, the transmission belt 71 can rotate with the saplings. In addition, the mounting frame 72 is rotated and mounted on the mounting block 312. After all the saplings in the seedling storage box 31 have been transplanted, the transport vehicle 1 needs to return to replenish the saplings. When replenishing, the gear rack 33 is pulled, and under the transmission of the gear 722, the mounting frame 72 rotates 90°, so that the separator 711 faces the upper and lower positions, so as to avoid the separator 711 damaging the soil ball of the sapling when replenishing the saplings.

[0034] The method of using this invention is as follows: First, the seedlings are arranged in a matrix in the seedling storage box 31. Then, the transport vehicle 1 is controlled to move. During transplanting, the telescopic cylinder 5 drives the drilling mechanism to descend, and the driving component 22 drives the drilling component to rotate forward. After the hole is drilled, the micro cylinder 6 drives multiple conical segments 2121 to move away from each other. Then, the conveying mechanism 4 puts the seedlings into the top of the rotating cylinder 211. Then, the driving component 22 reverses the drilling component, and the telescopic cylinder 5 drives the entire drilling component to move slowly upward. During the reversal, the hole can collapse, thereby directly filling the seedling with soil. Then, the transport vehicle 1 is controlled to move to the next transplanting point.

[0035] The above provides a detailed description of a sandy land ecological restoration device provided by the present invention. The specific embodiments are described only to aid in understanding the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
