Description

Technical Field

[0001] This application relates to the field of landscape architecture, and in particular to a soil ball protection device for tree transplantation. Background Technology

[0002] With the rapid development of urban greening, people have higher and higher requirements for the quality of urban landscape green space construction. Large tree transplantation is a planting method adopted at a specific time and place to meet specific requirements. It can improve the ecological benefits of garden green spaces, optimize the green space structure, improve the environmental landscape, and promptly meet the greening and beautification needs of key construction projects and large-scale municipal construction.

[0003] During tree transplantation, the root ball of the excavated tree needs to be wrapped to prevent it from cracking and affecting the survival rate of the transplanted tree. The existing wrapping method usually uses non-woven fabric to wrap the root ball. However, in short-distance upright transplanting, the non-woven fabric cannot make the root ball bear the force evenly, which makes the root ball easy to crack. Utility Model Content

[0004] In order to improve the problem that non-woven fabric for root balls cannot ensure even stress distribution on the root ball, which leads to easy breakage of the root ball, this application provides a root ball protection device for tree transplantation.

[0005] The soil ball protection device for tree transplantation provided in this application adopts the following technical solution:

[0006] A root ball protection device for tree transplantation includes a support frame that cooperates with the lower half of the root ball. The support frame is composed of two unit frames spliced ​​together. The two opposite ends of the two unit frames are connected by connecting components. The inner side of each unit frame is covered with a covering layer. The bottom of each unit frame is provided with a placement opening. The two placement openings are arranged opposite each other to form a placement hole for pre-reserved soil. The unit frame is provided with a sealing component for sealing the placement hole.

[0007] By adopting the above technical solution, after the root ball is excavated, two unit frames are placed below the root ball and then spliced ​​together by connecting components to form a support frame that supports the root ball. At this time, the covering layer wraps the root ball, and the two placement openings form a placement hole for reserved soil. After the reserved soil is excavated, the placement hole is sealed by a sealing component. The support frame and sealing component support the entire root ball, which can improve the uniformity of the force on the root ball, thereby ensuring the integrity of the root ball.

[0008] In one specific implementation, the connecting assembly includes a connecting bolt and a connecting nut. One end of the connecting bolt is hinged to one of the unit frames, and the other unit frame is provided with a mounting port for inserting the connecting bolt into the mounting port. The connecting bolt can be inserted into the mounting port, and the connecting nut is threaded onto the end of the connecting bolt that passes through the mounting port, so as to be tightly fixed to the unit frame.

[0009] By adopting the above technical solution, when splicing two unit frames, the two unit frames are set opposite each other. Then, the connecting bolts are rotated and inserted into the installation holes on the opposite unit frames. Then, the connecting nuts are screwed onto the connecting bolts and pressed against the unit frames to complete the fixed connection between the two unit frames, thereby improving the convenience of the support frame for the installation of the root ball support.

[0010] In one specific implementation, each of the two opposite ends of the unit frame is fixedly provided with a lug plate, the connecting bolt is hinged to one of the lug plates, and the mounting port is provided on the other lug plate.

[0011] By adopting the above technical solution, the ear plate configuration improves the convenience of splicing and installing between the two unit frames.

[0012] In one specific implementation, a countersunk hole is provided on the ear plate where the mounting port is located, and the countersunk hole is connected to the mounting port so that the connecting nut can be inserted into the countersunk hole.

[0013] By adopting the above technical solution, when tightening the connecting nut, the connecting nut is inserted into the countersunk hole, which can effectively prevent the connecting nut from slipping, thereby improving the stability of the splicing of the two unit frames.

[0014] In one specific implementation, the sealing assembly includes a sealing plate and two sets of guide rails. The two sets of guide rails are respectively disposed at the bottom of the two unit frames so that the two guide rails can be opposite each other. The sealing plate is slidably connected to the two sets of guide rails and can slide along the guide rails to the bottom of the placement hole to seal the placement hole.

[0015] By adopting the above technical solution, after the two unit frames are spliced, the reserved soil below the root ball needs to be cut off. After cutting off, the sealing plate is inserted into a set of guide rails, and then the sealing plate is pushed to slide onto another set of guide rails. At this time, the sealing plate slides to the bottom of the placement hole and seals the placement hole. This can effectively prevent the soil in the root ball from falling off after the reserved soil is cut off. At the same time, the sealing plate supports the root ball and improves the uniformity of the force on the root ball.

[0016] In one specific implementation, each set of guide rails includes rail bodies disposed on both sides of the placement opening, and sliding grooves for inserting the sealing plate are provided on the opposite sides of the two rail bodies.

[0017] By adopting the above technical solution, two rails are set up to support the sealing plate, thereby improving the uniformity of the force on the sealing plate and increasing its strength.

[0018] In one specific implementation, a guide surface is provided on the side wall of the sliding groove, the guide surface being used to guide soil particles to slide out of the sliding groove.

[0019] By adopting the above technical solution, when soil particles enter the sliding groove, the soil particles slide out of the sliding groove along the guide surface, thereby effectively avoiding the distance of soil particles in the sliding groove and ensuring the stability of the sliding of the sealing plate.

[0020] In one specific implementation, the sealing plate has a cutting surface at its front end, which is capable of cutting the bottom of the root ball.

[0021] By adopting the above technical solution, a cutting surface is set to remove the excess part of the root ball, reducing the resistance when the sealing plate slides, making the sealing plate slide more smoothly.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. After excavating the root ball, place two unit frames under the root ball and then assemble them into a support frame that supports the root ball using connecting components. At this time, the covering layer wraps around the root ball, and the two placement openings form a placement hole for reserved soil. After the reserved soil is excavated, the placement hole is sealed with a sealing component. The support frame and sealing component support the entire root ball, which can improve the uniformity of the force on the root ball and thus ensure the integrity of the root ball.

[0024] 2. After the two unit frames are assembled, the reserved soil below the root ball needs to be cut off. After cutting off, insert the sealing plate into a set of guide rails, and then push the sealing plate to slide onto another set of guide rails. At this time, the sealing plate slides to the bottom of the placement hole and seals the placement hole. This can effectively prevent the soil in the root ball from falling off after the reserved soil is cut off. At the same time, the sealing plate supports the root ball and improves the uniformity of the force on the root ball. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a soil ball protection device for tree transplantation.

[0032] Reference Figure 1 A root ball protection device for tree transplantation includes a support frame 2 that cooperates with the lower half of the root ball 11. The support frame 2 is hemispherical and is composed of two unit frames 21 spliced ​​together. Each unit frame 21 is a quarter-sphere in shape and is a mesh structure made of several interwoven rigid rods. A covering layer 22 is laid on the inner side of each unit frame 21. In this embodiment, the covering layer 22 is a fleece blanket, which seals the voids in the unit frame 21 and effectively prevents soil particles from falling off. The two opposite ends of the two unit frames 21 are connected by connecting components 3.

[0033] Reference Figure 1 , Figure 2 Since a reserved soil 12 needs to be left below the root ball 11 after the root ball 11 is excavated to support the root ball 11, the bottom of both unit frames 21 is provided with a placement opening 211. The two placement openings 211 are arranged opposite each other. When the two unit frames 21 are spliced ​​into a support frame 2, the two placement openings 211 form a placement hole 212 for the reserved soil 12 to be placed. The unit frame 21 is provided with a sealing component 4 for sealing the placement hole 212.

[0034] After the root ball 11 is excavated, two unit frames 21 are placed below the root ball 11 and then spliced ​​together by the connecting components 3 to form a support frame 2 that supports the root ball 11. At this time, the covering layer 22 wraps the root ball 11, and the two placement openings 211 form a placement hole 212 for the reserved soil 12 to be placed. After the reserved soil 12 is excavated, the placement hole 212 is sealed by the sealing component 4. The support frame 2 and the sealing component 4 support the entire root ball 11, which can improve the uniformity of the force on the root ball 11, thereby ensuring the integrity of the root ball 11.

[0035] Reference Figure 1 , Figure 3 In this embodiment, the connecting component 3 includes connecting bolts 31 and connecting nuts 32. Ear plates 33 are fixedly provided on opposite ends of the two unit frames 21. The connecting bolts 31 are evenly distributed along the extension direction of the ear plates 33. One end of each connecting bolt 31 is hinged to one of the ear plates 33 to ensure that the connecting bolt 31 can rotate towards the other ear plate 33 when the hinge axis rotates. An installation port 34 is provided on the ear plate 33 opposite to the connecting bolt 31. The installation port 34 corresponds one-to-one with the connecting bolt 31. The connecting bolt 31 can be rotatably inserted into the installation port 34 and protrude a certain length from the installation port 34. The connecting nut 32 is threaded onto the end of the connecting bolt 31 that passes through the installation port 34. A countersunk hole 35 is provided on the ear plate 33, corresponding one-to-one with the installation port 34. The countersunk hole 35 communicates with the installation port 34. Rotating the connecting bolt 31 allows it to be inserted into the countersunk hole 35 and abut against and fixed to the corresponding ear plate 33. The countersunk hole 35 improves the stability of the connecting nut 32.

[0036] When splicing the two unit frames 21, the two unit frames 21 are set opposite each other. Then, the connecting bolt 31 is rotated and inserted into the mounting port 34 on the opposite unit frame 21. Then, the connecting nut 32 is screwed onto the connecting bolt 31 and pressed against the unit frame 21 to complete the fixed connection between the two unit frames 21, thereby improving the convenience of the support frame 2 for supporting the root ball 11.

[0037] Reference Figure 2 , Figure 4In this embodiment, the sealing component 4 includes a sealing plate 41 and two sets of guide rails 42. The two sets of guide rails 42 are respectively disposed at the bottom of the two unit frames 21. Each set of guide rails 42 includes a rail body 421 disposed on both sides of the placement opening 211. Each rail body 421 is fixedly connected to the unit frame 21. The two rail bodies 421 in the same set are arranged in parallel. The opposite sides of the two rail bodies 421 in the same set are provided with sliding grooves 422 for the sealing plate 41 to be inserted. The sliding grooves 422 are arranged along the length direction of the rail body 421 and pass through both ends of the rail body 421. When the two unit frames 21 are spliced, the rail bodies 421 in the two sets of guide rails 42 are arranged opposite each other to ensure that the sealing plate 41 can slide into the sliding groove 422 on the other set of guide rails 42.

[0038] Reference Figure 2 , Figure 4 When the sealing plate 41 is located in the sliding groove 422 within the two sets of rails 421, the sealing plate 41 is positioned below the placement hole 212 to seal the placement hole 212. A guide surface 43 is provided on the bottom side wall of the sliding groove 422, and the distance between the two guide surfaces 43 gradually decreases from top to bottom to ensure that soil particles slide out of the sliding groove 422. When soil particles enter the sliding groove 422, they slide out of the sliding groove 422 along the guide surface 43, effectively avoiding the distance between soil particles in the sliding groove 422 and ensuring the stability of the sliding of the sealing plate 41.

[0039] Reference Figure 1 The sealing plate 41 has a cutting surface 44 at its front end. The cutting surface 44 forms a cutting edge at the front end of the sealing plate 41, which can cut the bottom of the root ball 11. The cutting surface 44 removes the excess part of the root ball 11, reduces the resistance when the sealing plate 41 slides, and makes the sealing plate 41 slide more smoothly.

[0040] The implementation principle of the root ball protection device for tree transplantation in this application embodiment is as follows: After the root ball 11 is excavated, two unit frames 21 are placed below the root ball 11. Then, the connecting bolts 31 are rotated and inserted into the mounting holes 34 on the opposite unit frames 21. Then, the connecting nuts 32 are screwed onto the connecting bolts 31 and pressed against the unit frames 21 to complete the fixed connection between the two unit frames 21. The splicing forms a support frame 2 to support the root ball 11. At this time, the covering layer 22 wraps the root ball 11. At the same time, the two placement holes 211 form a placement hole 212 for the reserved soil 12 to be placed. After the reserved soil 12 is excavated, the sealing plate 41 is slid into the sliding groove 422 of the two sets of rails 421 to seal the placement hole 212. Through the support of the support frame 2 and the sealing component 4, the uniformity of the force on the root ball 11 can be improved, thereby ensuring the integrity of the root ball 11.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
