Technical Field

[0001] This invention relates to a tree planting device, specifically an integrated pit digging and filling tree planting device, belonging to the field of pit digging and filling technology. Background Technology

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of trees to play a protective role. It is an important part of the national economy. In the human and biosphere, forestry engages in the cultivation, protection and utilization of forest resources through advanced science and technology and management methods, giving full play to the multiple benefits of forests, and sustainably managing forest resources to promote the coordinated development of population, economy, society, environment and resources. In forestry development, tree planting is an essential link, and planting equipment is required when planting trees.

[0003] According to patent number CN 114521362 A, the invention belongs to the field of forestry planting equipment, especially a planting device for afforestation and greening that integrates digging and covering functions. Addressing the problem that after planting trees, the excavated soil placed on the ground is pushed back into the pit, easily burying contaminated soil from the ground surface, affecting the growth and survival of tree roots, the following solution is proposed: It includes a platform and a lifting cylinder. Two symmetrical guide frames are fixedly connected to the outer circumference of the lifting cylinder. The invention also proposes a method for using the planting device for afforestation and greening that integrates digging and covering functions, including the following steps: S1: Pull the device to the desired planting position using the handle, and then press the lifting cylinder downwards using the pressing frame. This invention can prevent contaminated soil from entering the pit, facilitate the growth of tree roots, and reduce the labor intensity of workers. It can also automatically tap the storage hopper, reducing the amount of manual cleaning.

[0004] Traditional pit-digging and burying devices require manual filling after digging the pits for planting trees, which is time-consuming and labor-intensive. In addition, the digging devices cannot be used for planting trees at the same time, making it inconvenient to accurately locate trees of different sizes. Accurate positioning of trees for planting is often done with another tool, making the practicality of pit-digging and burying devices relatively poor. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide an integrated tree planting and burial device for digging and filling pits to solve the above-mentioned problems. This addresses the issue that in the prior art, after digging the pits for planting trees, the filling is done manually, which wastes time and manpower. In addition, the digging device is generally not suitable for planting trees at the same time, making it inconvenient to accurately locate trees of different sizes. Accurate positioning of trees for planting is often done with another tool, resulting in poor practicality of the pit-digging and filling device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an integrated tree planting and greening device for digging and filling pits, comprising a support frame, a support ring inside the support frame, three telescopic rods fixedly connected to the outer side of the support ring, a fixing buckle fixedly connected to one side of each telescopic rod, a support fixing plate outside the fixing buckle, the fixing buckle slidably connected to the top of the support fixing plate, a limit groove formed on the top of the support fixing plate, two strip grooves formed on one side of both the fixing buckle and the support fixing plate, and circular holes formed inside both the fixing buckle and the support fixing plate. The groove is fitted with a limiting plate, which is inserted into the groove on one side of the fixing buckle. Then, the supporting ring is fixed by passing through the limiting plate, the fixing buckle and the supporting fixing plate in sequence with the first bolt. This structure is beneficial for the quick installation and disassembly of the digging head. This digging and filling device can not only dig holes in the ground to plant trees, but also easily disassemble the digging and filling component for planting trees. The structure is simple and highly practical. The limiting plate has two first bolts connected by threads inside. The bottom of the support frame is equipped with a filling component for filling the excavated soil.

[0009] Preferably, the landfill assembly includes a rotating rod, a first gear fixedly connected to the outer side of the rotating rod, a first gear ring meshing with one side of the first gear, a second gear ring fixedly connected inside the first gear ring, a second gear meshing with the inside of the second gear ring, a first vertical rod fixedly connected inside the second gear, a second vertical rod slidably connected to the outer side of the first vertical rod, a second bolt threaded between the first and second vertical rods, and a soil filling plate rotatably connected to the outer side of the second vertical rod. The soil filling plate maintains the same angle and revolves along the bottom of the support frame without rotating on its own axis. This allows soil around the planting pit to be scraped into the tree pit through the soil filling plate, thus filling the tree cavity. This structure is beneficial. The system automatically corrects the planting position of trees. After the tree planting position is corrected, the soil excavated can be automatically filled into the tree hole by rotating the soil filling plate, eliminating the need for manual filling and saving time and manpower. The number of second vertical rods is set to two, with the other second vertical rod fixedly connected to the top of the soil filling plate. The first and second vertical rods are fixed together by a second bolt. After adjusting the distance between the first and second vertical rods, they can be fixed with the second bolt. A second gear ring is set to drive the second gear to move around the outside of the second gear ring, thereby driving the soil filling plate to rotate at a fixed angle to scrape the soil around the pit into the pit.

[0010] Preferably, a second motor is fixedly connected to the top of the support frame, and the output end of the second motor is fixedly connected to a rotating rod. The rotating rod passes through the support frame and is rotatably connected to the support frame. A circular hole is opened inside the support frame, and the first gear is set inside the circular hole. The first gear drives the first gear ring to rotate, thereby driving the second gear ring to revolve.

[0011] Preferably, the bottom of the support frame is provided with a circular groove, and the first toothed ring and the second toothed ring are both disposed inside the circular groove. The first toothed ring and the second toothed ring are both configured as two half-circles joined together. The two first vertical rods are slidably connected to the bottom of the support frame. By setting the first toothed ring and the second toothed ring as half-circles, it is convenient to disassemble the digging head and facilitate the planting of trees.

[0012] Preferably, the support frame consists of two semicircles, and three first hydraulic push rods are fixedly connected to one side of the support frame. The first hydraulic push rods are fixedly connected to one side of the support fixing plate. Three grooves are provided on the top of the support frame, and the support frame and the support fixing plate are slidably connected through the grooves. The support fixing plate is used to support the support ring.

[0013] Preferably, a circular rotating plate is rotatably connected inside the supporting ring, a first motor is fixedly connected to the top of the supporting ring, and a digging cutter head is fixedly connected to the output end of the first motor. The digging cutter head passes through the circular rotating plate and is rotatably connected to the circular rotating plate. The first motor is used to drive the digging cutter head to rotate and dig the ground.

[0014] Preferably, a fixing block is fixedly connected to the top of the support frame, and a threaded hole is opened inside the fixing block. A third bolt is provided inside the threaded hole, and the fixing block and the third bolt are threadedly connected through the threaded hole. The third bolt is used to fix the two support frames together.

[0015] Preferably, a second hydraulic push rod is fixedly connected to the top of the support frame, and the number of the second hydraulic push rods is set to three. The digging cutter head is disposed inside the three second hydraulic push rods, and the second hydraulic push rods are used to drive the support frame to rise and fall.

[0016] Preferably, the cross-sectional shape of the fixing buckle is set to a cross shape, and the fixing buckle is adapted to the limiting groove. By setting the cross-section of the fixing buckle to a cross shape, the support frame is fixed.

[0017] Preferably, the number of circular holes is set to multiple, and the circular holes are set inside the limiting plate. The limiting plate and the first bolt are connected by threads through the circular holes. The first bolt is used to fix the digging head, and the circular holes allow the first bolt to be set inside the circular holes, so as to quickly fix the digging head and prevent the digging head from shaking during cutting.

[0018] This invention provides an integrated tree planting and greening device that involves digging and filling pits, which has the following beneficial effects:

[0019] 1. This integrated pit-digging and burying tree planting device allows the fixing buckle to be removed along the inside of the limiting slot, at which point the entire pit-digging head can be removed. When it is necessary to install the pit-digging head, first align the fixing buckle inside the limiting slot. After the fixing buckle slides down along the limiting slot, the limiting plate can be inserted into the strip groove on one side of the fixing buckle. Then, the first bolt passes through the limiting plate, fixing buckle, and supporting fixing plate in sequence to fix the supporting ring. This structure facilitates the quick installation and disassembly of the pit-digging head. This pit-digging and burying device can not only dig pits for planting trees, but also allows for easy disassembly of the pit-digging and burying components for convenient tree planting. It has a simple structure and strong practicality.

[0020] 2. This integrated tree planting and burial device involves a second vertical rod rotating to drive a soil burial plate to revolve. Another second vertical rod is fixedly connected to the top of the soil burial plate. Limited by one of the second vertical rods, the soil burial plate maintains the same angle as it revolves along the bottom of the support frame without rotating on its own axis. This allows soil from around the planting pit to be scraped into the pit through the soil burial plate, thus filling the tree cavity. This structure facilitates automatic correction of the tree's planting position. After correction, the rotation of the soil burial plate automatically fills the tree cavity with the excavated soil, eliminating the need for manual filling and saving time and manpower.

[0021] 3. The integrated tree planting and burial device for digging and filling pits can adapt to different digging depths by means of the telescopic relationship between the first and second vertical rods, which is fixed by the second bolt, during the use of the soil burial plate. This avoids the soil burial plate breaking when digging pits using the device. Attached Figure Description

[0039] This invention provides an integrated tree planting and greening device that combines digging and filling.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The device includes a support frame 1, with a support ring 2 inside. Three telescopic rods 201 are fixedly connected to the outside of the support ring 2. A fixing buckle 202 is fixedly connected to one side of each telescopic rod 201. A support fixing plate 203 is provided outside the fixing buckle 202. The fixing buckle 202 is slidably connected to the top of the support fixing plate 203. When the fixing buckle 202 slides down along the limiting groove 204, the limiting plate 207 can be inserted into the strip groove 205 on one side of the fixing buckle 202. Then, the support ring 2 is fixed by the first bolt 208 passing through the limiting plate 207, the fixing buckle 202, and the support fixing plate 203 in sequence. This structure facilitates the quick installation and disassembly of the digging cutter head 9, enabling this digging and filling device to not only... While digging holes for planting trees, the hole-digging and filling components can be easily disassembled for convenient tree planting. The structure is simple and highly practical. The top of the support fixing plate 203 has a limiting slot 204. The fixing buckle 202 and the support fixing plate 203 each have two strip grooves 205. The fixing buckle 202 and the support fixing plate 203 each have a circular hole 206. The strip groove 205 is fitted with a limiting plate 207. The limiting plate 207 has two first bolts 208 threadedly connected inside. The bottom of the support frame 1 is equipped with a filling component for filling the excavated soil. The support frame 1 is composed of two semicircles. Three first hydraulic push rods 4 are fixedly connected to one side of the support frame 1. The first hydraulic push rods 4 are fixedly connected to one side of the support fixing plate 203.

[0041] The support frame 1 has three grooves on its top. The support frame 1 and the support fixing plate 203 are slidably connected through the grooves. The support fixing plate 203 is used to support the support ring 2. A circular rotating plate 10 is rotatably connected inside the support ring 2. A first motor 8 is fixedly connected to the top of the support ring 2. A digging cutter head 9 is fixedly connected to the output end of the first motor 8. The digging cutter head 9 passes through the circular rotating plate 10 and is rotatably connected to the circular rotating plate 10. Three second hydraulic push rods 7 are fixedly connected to the top of the support frame 1. The number of digging cutter heads 9 is set at three. Inside the second hydraulic push rod 7, the support frame 1 is raised and lowered by the second hydraulic push rod 7. The cross-sectional shape of the fixing buckle 202 is set to cross shape. The fixing buckle 202 and the limiting buckle groove 204 are adapted to each other. By setting the cross-section of the fixing buckle 202 to cross shape, the support frame 1 is fixed. The number of circular holes 206 is set to multiple. The circular holes 206 are set inside the limiting plate 207. The limiting plate 207 and the first bolt 208 are threadedly connected through the circular holes 206. The first bolt 208 is used to fix the digging cutter head 9.

[0042] Specifically, firstly, a pit is dug in the ground. The support frame 1 can be positioned at the top of the pit. Then, the first motor 8 is started, driving the digging cutter head 9 to rotate. The pit depth can be adjusted by raising and lowering the digging cutter head 9 using the second hydraulic push rod 7. After digging all the required pits, a crane can be used to hoist large trees into the pits. Then, the first bolt 208 is rotated. Rotating the first bolt 208 causes it to unscrew from the support fixing plate 203, the fixing buckle 202, and the inside of the bolt 208. The limiting plate 207 is then pulled out, and the support ring 2 is pulled upwards. The upward movement of the support ring 2 causes the telescopic rod 201 to move upwards, which in turn causes the fixing buckle 202 to move upwards. Moving upwards, the fixing buckle 202 can be removed along the inside of the limiting groove 204, allowing the entire digging head 9 to be removed. When installing the digging head 9, first align the fixing buckle 202 inside the limiting groove 204. After the fixing buckle 202 slides down along the limiting groove 204, the limiting plate 207 can be inserted into the strip groove 205 on one side of the fixing buckle 202. Then, the first bolt 208 is used to sequentially pass through the limiting plate 207, the fixing buckle 202, and the supporting fixing plate 203 to fix the supporting ring 2. This structure facilitates the quick installation and disassembly of the digging head 9, enabling this digging and burying device to not only dig holes for planting trees but also to easily disassemble the digging and burying components for convenient tree planting. The structure is simple and highly practical.

[0043] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13The landfill assembly includes a rotating round rod 3. A first gear 301 is fixedly connected to the outer side of the rotating round rod 3. A first gear ring 302 is meshed with one side of the first gear 301. A second gear ring 303 is fixedly connected inside the first gear ring 302. A second gear 304 is meshed with inside the second gear ring 303. A first vertical rod 305 is fixedly connected inside the second gear 304. A second vertical rod 306 is slidably connected to the outer side of the first vertical rod 305. A second bolt 307 is threaded between the first vertical rod 305 and the second vertical rod 306. A soil landfill plate 308 is rotatably connected to the outer side of the second vertical rod 306. One of the second vertical rods 306 is a limiting device. At this time, the soil filling plate 308 maintains the same angle and revolves along the bottom of the support frame 1 without rotating on its own axis. At this time, the soil around the planting pit can be scraped into the tree pit through the soil filling plate 308 to fill the tree hole. This structure is beneficial for automatically correcting the planting position of the tree. After correcting the planting position of the tree, the soil filling plate 308 can rotate to automatically fill the tree hole with the excavated soil without manual filling, saving time and manpower. The number of second vertical rods 306 is set to two, and the other second vertical rod 306 is fixedly connected to the top of the soil filling plate 308.

[0044] The first vertical rod 305 and the second vertical rod 306 are fixed together by the second bolt 307. After adjusting the distance between the first vertical rod 305 and the second vertical rod 306, they can be fixed by the second bolt 307. The second gear 304 can be driven by the second gear ring 303 to move around the outside of the second gear ring 303, thereby driving the soil filling plate 308 to revolve at a fixed angle to scrape the soil around the pit into the pit. The top of the support frame 1 is fixedly connected to the second motor 11. The output end of the second motor 11 is fixedly connected to the rotating round rod 3. The rotating round rod 3 passes through the support frame 1 and is rotatably connected to the support frame 1. The support frame 1 has a round hole inside, and the first gear 301 is set inside the round hole. The first toothed ring 302 rotates, which in turn drives the second toothed ring 303 to revolve. The bottom of the support frame 1 has a circular groove, and both the first toothed ring 302 and the second toothed ring 303 are set inside the circular groove. The first toothed ring 302 and the second toothed ring 303 are both set as two semicircles joined together. The two first vertical rods 305 are slidably connected to the bottom of the support frame 1. By setting the first toothed ring 302 and the second toothed ring 303 as semicircles, it is convenient to disassemble the digging cutter head 9 and to facilitate the planting of trees. The top of the support frame 1 is fixedly connected to a fixing block 5. The fixing block 5 has a threaded hole inside, and a third bolt 6 is set inside the threaded hole. The fixing block 5 and the third bolt 6 are connected by threads through the threaded hole. The third bolt 6 is used to fix the two support frames 1 together.

[0045] Specifically, after disassembling the digging head 9, the third bolt 6 is rotated to disassemble the two semicircular support frames 1. Once the support frame 1 is separated into two semicircles, these two semicircular support frames 1 are secured to the outside of the tree. The two support frames 1 are then connected together using the third bolt 6. The tree is now inside the support frame 1. The first hydraulic push rod 4 is then activated, causing the three support fixing plates 203 to move towards the center until all three support fixing plates 203 are against the outer ring of the tree. The first hydraulic push rod 4 is then stopped, and the second motor 11 is activated. The second motor 11 drives the rotating rod 3 to rotate, which in turn drives the first gear 301 to rotate. The first gear 301 then drives the first gear ring 302 to rotate, which in turn drives the second gear ring 303 to rotate. The second gear ring 303 then drives the second gear 304 to rotate, and the second gear 304 can rotate along the outside of the second gear ring 303. While rotating on its own axis, the second gear 304 rotates, driving the first vertical rod 305 to rotate. The first vertical rod 305 rotates, driving the second vertical rod 306 to rotate. The second vertical rod 306 rotates, driving the soil filling plate 308 to rotate. At this time, since one of the second vertical rods 306 is rotatably connected to the inside of the soil filling plate 308, while the other second vertical rod 306 is fixedly connected to the top of the soil filling plate 308, the soil filling plate 308 is limited by one of the second vertical rods 306. At this time, the soil filling plate 308 maintains the same angle and rotates along the bottom of the support frame 1 without rotating on its own axis. At this time, the soil around the planting pit can be scraped into the tree pit through the soil filling plate 308 to fill the tree hole. This structure is beneficial for automatically correcting the planting position of the tree. After correcting the planting position of the tree, the soil excavated can be automatically filled into the tree hole by the rotation of the soil filling plate 308, eliminating the need for manual filling, saving time and manpower.

[0046] Specifically, during the use of the soil cover plate 308, since the first vertical rod 305 and the second vertical rod 306 can extend and retract and are fixed by the second bolt 307, it can be adapted to different excavation depths and avoid breakage of the soil cover plate 308 when digging a pit using the device.

[0047] Working principle: The upward movement of the supporting ring 2 drives the telescopic rod 201 to move upward, and the upward movement of the telescopic rod 201 drives the fixing buckle 202 to move upward. At this time, the fixing buckle 202 can be taken out along the inside of the limiting groove 204, and the entire digging head 9 can be removed. When it is necessary to install the digging head 9, the fixing buckle 202 is first aligned with the inside of the limiting groove 204. After the fixing buckle 202 slides down along the limiting groove 204, the limiting plate 207 can be inserted into the strip groove 205 on one side of the fixing buckle 202. Then, the supporting ring 2 is fixed by the first bolt 208 passing through the limiting plate 207, the fixing buckle 202 and the supporting fixing plate 203 in sequence.

[0048] The rotation of the round rod 3 drives the first gear 301 to rotate, the rotation of the first gear 301 drives the first gear ring 302 to rotate, the rotation of the first gear ring 302 drives the second gear ring 303 to rotate, the rotation of the second gear ring 303 drives the second gear 304 to rotate, and the second gear 304 can rotate on its own axis and revolve around the periphery along the outer edge of the second gear ring 303. The rotation of the second gear 304 drives the first vertical rod 305 to rotate, the rotation of the first vertical rod 305 drives the second vertical rod 306 to rotate, and the rotation of the second vertical rod 306 drives the soil filling plate 308 to revolve around the periphery.
