Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] A tree transplanting support and protection device for forestry of the present invention is composed of Figures 1-10 given as:

[0034] Referring to Figures 1-2The present invention relates to a tree transplanting support and protection device for forestry, comprising two mutually hinged fixed rings 1, the outer sides of the two fixed rings 1 are both fixedly provided with a hinged support rod 24, the bottom end of the support rod 24 is hingedly provided with a support block 25, and the bottom end of the support block 25 is fixedly provided with a positioning rod 26; the free ends of the two fixed rings 1 are both fixedly provided with a mounting frame 2, the mounting frame 2 is in a U-shape, a mounting block 3 is rotatably provided inside the mounting frame 2, a rod hole 4 is opened on the mounting block 3, a fastening screw 5 is movably provided between the through holes on the two mounting blocks 3, and a fastening nut 6 is threadedly provided at one end of the fastening screw 5;

[0035] The above content is prior art, and its specific working process is as follows:

[0036] When in use, the two fixing rings 1 are opened and fitted on the outside of the transplanted tree, so that the three support rods 24 are evenly distributed around the transplanted tree, and then the positioning rod 26 is inserted into the soil by using the support block 25; then the fastening screw 5 is passed through the rod hole 4 on the mounting block 3 on one of the fixing rings 1, and the fastening screw 5 is passed out from the rod hole 4 on the mounting block 3 on the other fixing ring 1, and then the fastening screw 5 can be locked by the fastening nut 6 to complete the support and fixation of the transplanted tree.

[0037] Considering that the trunk diameter of the transplanted tree will change after growth, and the distance between the two fixing rings 1 will no longer change after being fixed, the two fixing rings 1 will over-compress the transplanted tree after a period of growth, which is not conducive to the growth of the tree. The following technical solution is proposed to solve this problem:

[0038] Reference Figures 3-6 A protective pad 7 is fixedly arranged on the inner side of the two fixing rings 1, and an arc-shaped cavity 8 and a connecting channel 9 are formed inside the protective pad 7. A sliding groove 10 is formed in the fixing ring 1 near one end of the fastening nut 6, and the sliding groove 10 is connected with the arc-shaped cavity 8 through the connecting channel 9, and the notch on the sliding groove 10 away from the end of the arc-shaped cavity 8 is connected with the outside world, and a driving member is slidingly arranged inside the sliding groove 10; wherein the driving member comprises a sliding block 12 slidingly arranged in the sliding groove 10, a telescopic spring 13 is arranged between the sliding block 12 and the sliding groove 10, a connecting rod 14 is fixedly arranged on the sliding block 12, a driving frame 15 is fixedly arranged on the connecting rod 14, a limiting groove 16 is formed inside the driving frame 15, a driving column 17 is hingedly arranged inside the limiting groove 16, and a torsion spring is arranged at the hinge between the driving column 17 and the limiting groove 16; tooth grooves 18 are evenly formed on the outer wall of the fastening nut 6, and the tooth grooves 18 are used in conjunction with the driving column 17;

[0039] Such a design can firstly protect the trees through the protective pad 7, and avoid direct hard contact between the fixing ring 1 and the trees; when the transplanted trees grow larger, the trees will squeeze the protective pad 7 and cause it to be compressed and deformed, so that the air pressure in the arc cavity 8 in the protective pad 7 is continuously increased, and the air pressure in the arc cavity 8 squeezes the sliding block 12 in the sliding groove 10 through the connecting channel 9 and causes it to move, and the sliding block 12 drives the driving frame 15 to move through the connecting rod 14, and the driving frame 15 drives the driving column 17 in its upper limit groove 16 to move, and the driving column 17 drives the fastening nut 6 to move through the tooth groove 18, and the effective length of the fastening screw 5 located between the two mounting frames 2 is lengthened by adjusting the fastening nut 6, so that the space between the two fixing rings 1 is enlarged to adapt to the growth process of the tree, which is more convenient; in order to ensure the continuity of the drive, a plurality of driving columns 17 can be provided according to actual needs.

[0040] It should be noted that since the arc-shaped cavity 8 is distributed on the outside of the two fixed rings 1, after the tree tilts, the space in the arc-shaped cavity 8 close to the tilting direction will become smaller, while the space in the arc-shaped cavity 8 away from the tilting direction will become larger. Therefore, the overall air pressure will not change significantly. Only when the trunk of the tree grows outward as a whole can the air pressure in the arc-shaped cavity 8 change significantly.

[0041] Considering that the space between the two fixing rings 1 of the above technical solution will change in real time as the tree grows, and since the moving distance of the driving frame 15 is limited, the change of the space between the two fixing rings 1 is also relatively limited, in order to solve this problem, the following technical solution is proposed:

[0042] Reference Figure 7 A mounting groove 11 is also formed in the fixing ring 1 near one end of the fastening nut 6. The mounting groove 11 is communicated with the sliding groove 10. A blocking member is arranged inside the mounting groove 11. The blocking member includes a blocking block 19 and a supporting spring 20 which are slidably arranged in the mounting groove 11. The blocking block 19 is located at one end near the connecting rod 14. A blocking slope 21 is formed on the blocking block 19. A groove 22 is formed on one side of the connecting rod 14 near the blocking block 19. A force storage slope 23 is formed in the groove 22 in a direction near the sliding block 12. The force storage slope 23 is used in conjunction with the blocking slope 21.

[0043] With this design, as the air pressure in the arc-shaped cavity 8 increases, the force storage slope 23 on the connecting rod 14 is restricted by the blocking slope 21 on the blocking block 19, resulting in the connecting rod 14 being able to move only slightly until the air pressure increases to the point where the force storage slope 23 is free from the restriction of the blocking slope 21. At this time, under the action of the high air pressure, the sliding block 12 drives the fastening nut 6 to rotate through the connecting rod 14, the driving frame 15, the driving column 17, and the tooth groove 18 in sequence, so as to adjust the effective length of the fastening screw 5 located between the two fixing rings 1. At this time, the space between the two fixing rings 1 becomes larger, and accordingly, the arc The air pressure in the cavity 8 will also decrease, and then under the action of the telescopic spring 13, the sliding block 12 returns to its original position, and the blocking block 19 re-enters the interior of the groove 22. During the movement of the driving frame 15, the driving column 17 is blocked by the fastening nut 6 and will first shrink to the interior of the limiting groove 16. After passing the fastening nut 6, under the action of the torsion spring, the driving column 17 is in a vertical state again to facilitate the next drive. In this way, the fastening nut 6 can be continuously adjusted so that the space between the two fixing rings 1 matches the growth of the tree.

[0044] Specifically, the support block 25 is cylindrical in shape, and the bottom of the positioning rod 26 is conical in shape.

[0045] Considering that transplanted trees need to be watered regularly to ensure their survival, the general method is to water them manually for a limited number of times, which will reduce the possibility of survival of some trees when no one takes care of them. In order to solve this problem, the following technical solutions are proposed:

[0046] Reference Figures 8-10 A water collecting membrane 27 is fixedly arranged between the two corresponding support rods 24, a water inlet 28 and a first water storage cavity 29 are formed inside the support rod 24, a second water storage cavity 30 is formed inside the support block 25, and a water discharge cavity 31 and a water discharge port 32 are formed inside the positioning rod 26, wherein the water inlet 28 is communicated with the first water storage cavity 29, the first water storage cavity 29 is communicated with the second water storage cavity 30 through a conduit, the second water storage cavity 30 is communicated with the water discharge cavity 31, and the water discharge cavity 31 is communicated with the water discharge port 32;

[0047] The bottom ends of the two membrane surfaces of the water collecting membrane 27 are fixedly provided with water guide bars 33, the middle part of the water guide bars 33 is higher than the two ends of the water guide bars 33, and water guide grooves 34 are symmetrically formed on the water guide bars 33, and the water guide grooves 34 are connected to the water inlet 28 on the support rod 24;

[0048] With such a design, when the humidity in the air is relatively high, such as in the early morning, the water in the air can be captured by the water collection film 27, condensed and then enter the interior of the first water storage cavity 29 in the support rod 24 along the water guide groove 34 and the water inlet 28. Subsequently, it is discharged through the conduit, the second water storage cavity 30, the water discharge cavity 31, and the water discharge port 32 in sequence. The water discharged through the water discharge port 32 will infiltrate into the soil around the roots of the tree, thus achieving the purpose of automatic watering.

[0049] Inside the water discharge cavity 31, a water storage chamber 35, a water discharge chamber 36, and a water control chamber 37 are formed in sequence from top to bottom. Among them, the water storage chamber 35 communicates with the second water storage cavity 30 in the support block 25. The water storage chamber 35 communicates with the water discharge chamber 36 through a water discharge hole 38. The water discharge port 32 communicates with the water discharge chamber 36 and is evenly distributed on the outside of the water discharge chamber 36. The water discharge chamber 36 communicates with the water control chamber 37 through a sealing hole 39. And a plurality of water permeable holes 40 communicating with it are formed on the outside of the water control chamber 37. A control member for controlling the water discharge hole 38 is arranged in the water control chamber 37;

[0050] The control member includes an expansion strip 41 arranged in the water control chamber 37. The shape of the expansion strip 41 is cylindrical. A driving rod 42 is fixedly arranged on the expansion strip 41. One end of the driving rod 42 passing through the sealing hole 39 is fixedly provided with a sealing block 43. The sealing block 43 is located inside the water discharge chamber 36 and is used in cooperation with the water discharge hole 38;

[0051] With such a design, when the humidity of the soil around the roots of the tree is relatively high, the water in the soil will enter the interior of the water control chamber 37 through the water permeable holes 40 and be absorbed by the expansion strip 41, causing the expansion strip 41 to expand and its length to increase. The expansion strip 41 drives the sealing block 43 to move through the driving rod 42, and the water discharge hole 38 is sealed by the sealing block 43. In this way, the water collected by the water collection film 27 can be stored through the water storage chamber 35, the second water storage cavity 30, and the first water storage cavity 29; when the soil around the roots of the tree is relatively dry, at this time, the water in the expansion strip 41 will be lost, resulting in a decrease in the length of the expansion strip 41. At this time, the expansion strip 41 drives the sealing block 43 to move through the driving rod 42, so that the sealing block 43 no longer seals the water discharge hole 38. In this way, the water stored in the water storage chamber 35 can enter the interior of the water discharge chamber 36 through the water discharge hole 38, and then be discharged to the surrounding soil through the water discharge port 32, achieving the purpose of automatic watering when the soil is relatively dry to ensure the normal growth of the tree.

[0052] Specifically, filter meshes are fixedly arranged inside the water discharge port 32 and inside the water permeable holes 40; with such a design, it can prevent the soil from entering the interior of the positioning rod 26.
