Description

Technical Field

[0001] This invention belongs to the field of tree protection technology, specifically a protective device for crabapple cultivation. Background Technology

[0002] Crabapple is a general and common name for several plants in the genus *Malus* and several plants in the genus *Chaenomeles*. Representative plants, crabapple and quince, are both shrubs or small trees in the Rosaceae family, and are well-known ornamental tree species in China, commonly cultivated throughout the country. Horticultural varieties include pink double-flowered and white double-flowered varieties. Crabapple trees are mostly used for urban greening and beautification as ornamental flowering plants.

[0003] Currently, crabapple trees often require support frames after planting due to their unstable root systems to prevent them from toppling over in strong winds. Existing support frame structures are relatively simple. When supporting crabapple trees, a ring-shaped component is usually placed over the outside of the tree, and then the support rod connected to the ring-shaped component is placed on the ground. Although this support method has a certain supporting effect on crabapple trees, the ring-shaped component restricts the growth and thickening of the tree, which is not conducive to the normal growth of the crabapple tree. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a protective device for crabapple cultivation.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

The first limiting plate is slidably disposed on the inner wall of the abutment box. The lower end of the first limiting plate extends between the two groups of the first arc-shaped protrusions, and the upper end extends below the limiting wheel.

[0017] As a further improvement of the present invention: a first slide rail is fixedly provided on the inner wall of the abutment box, and a first slider is fixedly provided on the side wall of the first limiting plate, and the first slider slides in cooperation with the first slide rail.

[0018] As a further improvement of the present invention: a telescopic sleeve is fixedly provided at the upper end of the support leg, and a telescopic rod is fixedly provided on the side wall of the abutment box. The end of the telescopic rod away from the abutment box extends into the interior of the telescopic sleeve and telescopically cooperates with the telescopic sleeve.

[0019] As a further improvement to the present invention: the driving component further includes two sets of second arc-shaped protrusions.

[0020] Two sets of the second arc-shaped protrusions are fixedly mounted on the circumferential sidewall of the rotating wheel. Vertically spaced sliding grooves are provided on the sidewall of the abutment box, and vertically distributed second slide rails are fixedly mounted on the inner wall of the abutment box.

[0021] The second limiting component includes a second limiting plate, a connecting rod, and a second limiting tooth.

[0022] One end of the connecting rod extends between the two sets of the second arc-shaped protrusions, and the other end extends from the slide groove to the outside of the abutment box and is fixedly connected to the second limiting plate.

A second slider is fixedly arranged at the bottom of the connecting rod, and the second slider slides in cooperation with the second slide rail.

[0023] As a further improvement of the present invention: a first support block is fixedly provided on the inner wall of the abutment box, and the first support block is connected to the rotating shaft by an elastic rope, the elastic rope being used to provide elastic tension to the rotating shaft.

[0024] As a further improvement of the present invention: a second support block is also fixedly provided on the inner wall of the abutment box, and the second support block is connected to the connecting rod through an elastic element, the elastic element being used to provide elastic tension to the connecting rod.

[0025] As a further improvement of the present invention: the elastic rope is a rubber rope or a silicone rope, and the elastic element is a spring or a metal spring sheet.

[0026] As a further improvement of the present invention: a mounting plate is fixedly provided at one end of the strap that extends to the outside of the corresponding abutment box, and the mounting plate is connected to the side wall of another set of abutment boxes by a number of fixing bolts.

[0027] As a further improvement to the present invention: the abutment box has an arc-shaped structure.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] In this embodiment of the invention, when supporting and protecting a crabapple tree, a ring structure formed by two sets of abutment boxes and two sets of straps can be placed over the outside of the crabapple tree, ensuring that the two sets of abutment boxes and straps are in close contact with the tree. Then, the support legs are placed on the ground. As the crabapple tree grows and thickens, it pushes the two sets of abutment boxes away from each other, causing them to move towards the two sets of support legs. Simultaneously, the crabapple tree pushes the two sets of straps, which in turn drive the two sets of rollers to rotate. As the rollers rotate, they adaptively unwind the straps. Thus, the two sets of abutment boxes and straps provide support to the crabapple tree without restricting its growth. Furthermore, when the crabapple tree encounters strong winds, the drive component can activate the first... The first limiting component restricts the rotation of the reel when it moves, preventing the reel from unwinding the straps. The second driving component restricts the extension and retraction between the abutment box and the support leg when it moves, preventing the abutment box from moving towards the support leg. In other words, the two sets of abutment boxes cannot move away from each other. Thus, the two sets of abutment boxes and the two sets of straps can stably maintain the ring structure, thereby providing stable support for the crabapple tree and preventing it from being blown down by strong winds. Compared with the prior art, it can provide stable support for the crabapple tree in strong winds, and can release the support for the crabapple tree when there are no strong winds, so as to avoid the protective device hindering the growth and thickening of the crabapple tree.

[0039] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Therefore, they should not be construed as limitations on this invention.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Please see Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a protective device for crabapple cultivation, including abutment boxes 10, scrolls 20, a drive assembly 40, a first limiting assembly 50, and a second limiting assembly 60. Two sets of abutment boxes 10 are provided, arranged opposite to each other. Support legs 101 are telescopically fitted to the sides of the two sets of abutment boxes 10 that are furthest from each other. Two sets of scrolls 20 are provided, with one end of each set extending into the interior of the two sets of abutment boxes 10 and rotatably engaging with them. Each set of scrolls 20 has a binding strap 30 wound around its exterior, with one end of each binding strap extending from the interior of its corresponding abutment box 10. Extending out and connected to the front side wall of another set of abutment boxes 10, the two sets of straps 30 and the two sets of abutment boxes 10 form a ring structure. Both sets of abutment boxes 10 are provided with the drive component 40, the first limiting component 50 and the second limiting component 60. In strong winds, the drive component 40 is used to drive the first limiting component 50 and the second limiting component 60 to move. When the first limiting component 50 moves, it restricts the rotation of the roller 20. When the second limiting component 60 moves, it restricts the extension and retraction between the abutment box 10 and the support leg 101.

[0044] When supporting and protecting a crabapple tree, a ring structure formed by two sets of abutment boxes 10 and two sets of straps 30 can be placed over the tree, ensuring that the abutment boxes 10 and straps 30 are in close contact with the tree. Then, the support legs 10 are placed on the ground. As the crabapple tree grows and thickens, it pushes the two sets of abutment boxes 10 away from each other, causing them to move towards the two sets of support legs 101. Simultaneously, the tree pushes the two sets of straps 30, which in turn rotate the two sets of rollers 20. As the rollers 20 rotate, they adapt to the unwinding of the straps 30. In this way, the abutment boxes 10 and straps 30 provide support to the crabapple tree without causing any damage. The growth of the crabapple tree is restricted. When the crabapple tree encounters strong winds, the drive component 40 can drive the first limit component 50 and the second limit component 60 to move. When the first limit component 50 moves, it restricts the rotation of the roller 20, so that the roller 20 cannot unwind the strap 30. When the second drive component 60 moves, it restricts the extension and retraction between the abutment box 10 and the support leg 101, so that the abutment box 10 cannot move towards the support leg 101. That is, the two sets of abutment boxes 10 cannot move away from each other. In this way, the two sets of abutment boxes 10 and the two sets of straps 30 can stably maintain the ring structure, thereby providing stable support for the crabapple tree and preventing the crabapple tree from being blown down by strong winds.

[0045] Please see Figure 5 , Figure 6 as well as Figure 7In one embodiment, the drive assembly 40 includes a rotating shaft 401, blades 402, a rotating wheel 403, and a first arc-shaped protrusion 404. One end of the rotating shaft 401 extends into the interior of the abutment box 10 and is fixedly connected to the rotating wheel 403, while the other end passes through the side wall of the abutment box 10 and extends to the outside of the abutment box 10. The rotating shaft 401 is rotatably engaged with the abutment box 10. Several sets of blades 402 are provided, and several sets of blades 402 are fixedly disposed on the shaft of the rotating shaft 401 located outside the abutment box 10. Two sets of the first arc-shaped protrusion 404 are provided, and two sets of the first arc-shaped protrusion 404 are fixedly disposed on the rotating shaft 401. On the circumferential sidewall of wheel 401, the first limiting component 50 includes a first limiting plate 501, a limiting wheel 503, and a first limiting tooth 504. The limiting wheel 503 is fixedly disposed outside the scroll 20. The first limiting tooth 504 is provided in several groups. Several first limiting teeth 504 are fixedly disposed at the bottom of the limiting wheel 503. Several first limiting teeth 504 are distributed in a ring at intervals at the bottom of the limiting wheel 503. The first limiting plate 501 is slidably disposed on the inner wall of the abutment box 10. The lower end of the first limiting plate 501 extends between two groups of first arc-shaped protrusions 404, and the upper end extends below the limiting wheel 503.

[0046] When the crabapple tree is not exposed to strong winds, several leaves 402, rotating shaft 401, rotating wheel 403, and two sets of first arc-shaped protrusions 404 remain stationary. The lower end of the first limiting plate 501 extends between the two sets of first arc-shaped protrusions 404, and the upper end of the first limiting plate 501 does not contact several first limiting teeth 504. At this time, as the crabapple tree grows thicker, it pushes the two sets of abutment boxes 10, causing them to move away from each other. Simultaneously, it pushes the two sets of binding straps 30, causing them to pull the corresponding scrolls 20 and unwind them. The area of ​​the annular structure formed by the two sets of abutment boxes 10 and the two sets of binding straps 30 increases in adaptability as the crabapple tree grows thicker. When the crabapple tree encounters strong winds, the strong wind blows several leaves 402, which in turn drives the rotating shaft 401 to rotate. When the rotating shaft 401 rotates, it drives the rotating wheel 403 and two sets of first arc-shaped protrusions 404 to rotate. When one set of first arc-shaped protrusions 404 rotates, it pushes the first limiting plate 501, causing the first limiting plate 501 to move upward. When the first limiting plate 501 moves upward, its upper end inserts between two adjacent sets of first limiting teeth 504, thereby restricting the rotation of the limiting wheel 503. After the rotation of the limiting wheel 503 is restricted, the rotation of the scroll 20 is also restricted, so that the binding strap 30 cannot be unwound from the outside of the scroll 20. When the binding strap 30 cannot be unwound, it can provide stable support for the crabapple tree.

[0047] Please see Figure 6In one embodiment, a vertically distributed first slide rail 104 is fixedly provided on the inner wall of the abutment box 10, and a first slider 502 is fixedly provided on the side wall of the first limiting plate 501, and the first slider 502 slides in cooperation with the first slide rail 104.

[0048] When the two sets of first arc-shaped protrusions 404 rotate and push the first limiting plate 501, the first limiting plate 501 can move upward smoothly through the sliding cooperation between the first slider 502 and the first slide rail 104, and then smoothly insert between two adjacent sets of first limiting teeth 504 to realize the rotation restriction of the scroll 20.

[0049] Please see Figure 5 as well as Figure 6 In one embodiment, a telescopic sleeve 102 is fixedly provided on the upper end of the support leg 101, and a telescopic rod 109 is fixedly provided on the side wall of the abutment box 10. The end of the telescopic rod 109 away from the abutment box 10 extends into the interior of the telescopic sleeve 102 and telescopically cooperates with the telescopic sleeve 102.

[0050] When the crabapple tree does not encounter strong winds, as the crabapple tree grows thicker, it pushes the two sets of abutment boxes 10 so that the two sets of abutment boxes 10 move away from each other. At this time, the abutment boxes 10 drive the telescopic rod 109 to move into the telescopic sleeve 102.

[0051] Please see Figure 5 as well as Figure 6 In one embodiment, the drive assembly 40 further includes two sets of second arc-shaped protrusions 405, which are fixedly disposed on the circumferential sidewall of the rotating wheel 403. The sidewall of the abutment box 10 is provided with vertically oriented sliding grooves 103, and the inner wall of the abutment box 10 is fixedly disposed with vertically distributed second slide rails 110. The second limiting assembly 60 includes a second limiting plate 601, a connecting rod 602, and a second limiting tooth 603. One end of the connecting rod 602 extends between the two sets of second arc-shaped protrusions 405, and the other end extends from the sliding groove 103 to the outside of the abutment box 10 and is fixedly connected to the second limiting plate 601. The second limiting tooth 603 is provided in several sets, and the several second limiting teeth 603 are fixedly disposed on the upper part of the telescopic sleeve 102 and distributed at intervals along the length direction of the second telescopic sleeve 102. A second slider 604 is fixedly disposed at the bottom of the connecting rod 602, and the second slider 604 slides in cooperation with the second slide rail 110.

[0052] When strong winds act on several blades 402 and drive the rotating wheel 403 to rotate via the rotating shaft 401, the rotating wheel 403 can also drive two sets of second arc-shaped protrusions 405 to rotate. When one set of arc-shaped protrusions 405 rotates, it acts on the connecting rod 602, causing the connecting rod 602 to slide downward along the inside of the slide groove 103. When the connecting rod 602 slides down, it causes the second limiting plate 601 to move downward, and at the same time, it causes the second slider 604 to slide down along the second slide rail 110. When the second limiting plate 601 moves down, its lower end extends to between two adjacent sets of second limiting teeth 603, thereby limiting the telescopic rod 109 and the telescopic sleeve 102 to a non-extendable state. At this time, the outrigger 101 can provide stable support for the abutment box 10 through the telescopic sleeve 102 and the telescopic rod 109, thereby providing stable support for the crabapple tree and preventing the crabapple tree from being overturned by strong winds.

[0053] Please see Figure 6 In one embodiment, a first support block 105 is fixedly provided on the inner wall of the abutment box 10. The first support block 105 is connected to the rotating shaft 401 by an elastic rope 106, which is used to provide elastic tension to the rotating shaft 401.

[0054] When a strong wind blows several blades 402 and causes the rotating shaft 401 to rotate, the elastic rope 106 is stretched and wound around the outside of the rotating shaft 401. When the strong wind disappears, the elastic rope 106 pulls the rotating shaft 401 and causes the rotating shaft 401 to rotate in the opposite direction, thereby causing the rotating wheel 403, the two sets of first arc-shaped protrusions 404 and the two sets of second arc-shaped protrusions 405 to rotate in the opposite direction, realizing the reset of the two sets of first arc-shaped protrusions 404 and the two sets of second arc-shaped protrusions 405. When the two sets of first arc-shaped protrusions 404 flip and reset, the first limiting plate 501 moves downward by its own weight, and the upper end of the first limiting plate 501 is removed from between two adjacent sets of first limiting teeth 504 to release the rotation restriction of the winding shaft 20.

[0055] Please see Figure 6 In one embodiment, a second support block 107 is also fixedly provided on the inner wall of the abutment box 10. The second support block 107 is connected to the connecting rod 602 through an elastic element 108, which is used to provide elastic tension to the connecting rod 602.

[0056] When a strong wind blows several blades 402, causing the rotating shaft 401, the rotating wheel 404, and the two sets of second arc-shaped protrusions 405 to rotate, one set of second arc-shaped protrusions 405 pushes the connecting rod 602, causing the connecting rod 602 to move the second limiting plate 601 downward. At this time, the elastic element 108 is stretched. When the strong wind disappears, the elastic rope 106 pulls the rotating shaft 401, causing the two sets of second arc-shaped protrusions 405 to flip and reset. At this time, the elastic element 108 pulls the connecting rod 602, causing the connecting rod 602 to move upward. The connecting rod 602 moves the second limiting plate 601 upward, causing the lower end of the second limiting plate 601 to be removed from between two adjacent sets of second limiting teeth 603, thus limiting the extension and retraction between the telescopic sleeve 102 and the telescopic rod 109.

[0057] In one embodiment, the elastic rope 106 can be a rubber rope or a silicone rope, and there is no limitation here.

[0058] In one embodiment, the elastic element 108 can be a spring or a metal sheet, and there is no limitation on this.

[0059] Please see Figure 4 In one embodiment, the end of the strap 30 extending to the outside of the corresponding abutment box 10 is fixedly provided with an mounting plate 301, and the mounting plate 301 is connected to the side wall of another set of abutment boxes 10 by a plurality of fixing bolts 302.

[0060] Initially, the mounting plate 301 is not connected to the side wall of the abutment box 10 by the fixing bolts 302. When providing support and protection, the two sets of abutment boxes 10 can be abutted against the opposite side walls of the crabapple tree, and then the straps 30 can be pulled to attach the mounting plate 301 to the side wall of the other set of abutment boxes 10. Then, the mounting plate 301 can be fixed to the side wall of the abutment box 10 by the fixing bolts 302, so that the two sets of abutment boxes 10 and the two sets of straps 30 form a ring structure around the crabapple tree.

[0061] In one embodiment, the abutment box 10 has an arc-shaped structure to improve the fit between the abutment box 10 and the crabapple tree, thereby enhancing the support and protection effect of the crabapple tree.

[0062] The working principle of this invention is as follows:

[0063] Initially, the mounting plate 301 is not connected to the side wall of the abutment box 10 by the fixing bolts 302. When providing support and protection, the two sets of abutment boxes 10 can be placed against the opposite side walls of the crabapple tree, and then the straps 30 can be pulled to attach the mounting plate 301 to the side wall of the other set of abutment boxes 10. Then, the mounting plate 301 is fixed to the side wall of the abutment box 10 by the fixing bolts 302, thereby forming a ring around the crabapple tree with the two sets of abutment boxes 10 and the two sets of straps 30. In this configuration, the two sets of binding straps 30 and the two sets of abutment boxes 10 are in close contact with the crabapple tree. As the crabapple tree grows and thickens, the thickening tree pushes the two sets of abutment boxes 10 and the two sets of binding straps 30, causing the two sets of abutment boxes 10 to move away from each other. The two sets of binding straps 30 are also pushed, causing the two sets of rollers 20 to rotate. The two sets of binding straps 30 extend outward from inside the two sets of abutment boxes 10. At this time, the area of ​​the ring structure formed by the two sets of abutment boxes 10 and the two sets of binding straps 30 increases, thus preventing the thickening tree from growing too thick. The crabapple tree causes a restriction; when the crabapple tree encounters a strong wind, the strong wind blows the leaves 402, which in turn drives the rotating shaft 401 to rotate. The rotating shaft 401 drives the rotating wheel 403, the two sets of first arc-shaped protrusions 404, and the two sets of second arc-shaped protrusions 405 to rotate. One set of first arc-shaped protrusions 404 pushes the first limiting plate 501 to move upward, and one set of second arc-shaped protrusions 405 pushes the connecting rod 602 to move downward. When the first limiting plate 501 moves upward, its upper end extends to a certain adjacent two sets of first limiting plates. Between the teeth 504, the rotation of the limiting wheel 503 and the reel 20 is restricted, thereby preventing the reel 20 from unwinding the strap 30. When the connecting rod 602 moves down, it drives the second limiting plate 601 to move down. The lower end of the second limiting plate 601 extends to between two adjacent sets of second limiting teeth 603, so as to limit the abutment box 10 and the support leg 101 to a state where they cannot move relative to each other. At this time, the two sets of abutment boxes 10 and the two sets of straps 30 stably provide support and protection for the crabapple tree.

[0064] In this embodiment of the invention, when supporting and protecting a crabapple tree, a ring structure formed by two sets of abutment boxes 10 and two sets of straps 30 can be placed over the outside of the crabapple tree, so that the two sets of abutment boxes 10 and two sets of straps 30 are in close contact with the crabapple tree. Then, the support legs 10 are placed on the ground. As the crabapple tree grows and thickens, it pushes the two sets of abutment boxes 10 away from each other, and the two sets of abutment boxes 10 move towards the two sets of support legs 101 respectively. At the same time, the crabapple tree pushes the two sets of straps 30, and the two sets of straps 30, under the force, drive the two sets of rollers 20 to rotate. When the two sets of rollers 20 rotate, they adaptively unwind the two sets of straps 30. In this way, the two sets of abutment boxes 10 and two sets of straps 30 do not restrict the growth of the crabapple tree while providing support. When the crabapple tree encounters strong winds, the drive component 40 can drive the second set of straps 30 to rotate. When the first limiting component 50 and the second limiting component 60 move, the first limiting component 50 restricts the rotation of the reel 20, preventing the reel 20 from unwinding the strap 30. When the second driving component 60 moves, it restricts the extension and retraction between the abutment box 10 and the support leg 101, preventing the abutment box 10 from moving towards the support leg 101. In other words, the two sets of abutment boxes 10 cannot move away from each other. Thus, the two sets of abutment boxes 10 and the two sets of straps 30 can stably maintain the ring structure, thereby providing stable support for the crabapple tree and preventing the crabapple tree from being blown down by strong winds. Compared with the prior art, it can provide stable support for the crabapple tree in strong wind weather, and at the same time, it can release the support state for the crabapple tree when there is no strong wind weather, so as to avoid the protective device from hindering the growth and thickening of the crabapple tree.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0066] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity, and those skilled in the art should consider the specification as a whole.
