Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant protection, in particular to a pomegranate tree winter anti-freezing protection structure. BACKGROUND

[0002] Pomegranate trees are widely planted because the pomegranates on the trees are rich in nutrients and contain various nutrients needed by the human body, such as vitamin C and B vitamins, organic acids, sugars, proteins, fats, and minerals such as calcium, phosphorus, and potassium. Therefore, pomegranate trees are widely planted. For pomegranate trees that are thick and tall, they have high cold resistance and pressure resistance and can withstand the entire winter. However, for young pomegranate trees, especially in winter, their cold resistance and pressure resistance are weak, so it is necessary to protect the pomegranate trees from freezing. For large pomegranate trees, the conventional method is to wrap the tree trunk with cling film, thermal felt, and cling film in sequence to achieve anti-freezing protection, that is, mainly to protect the tree trunk. However, for small pomegranate trees, the conventional method is to fill thermal grass in a nylon bag and then wrap the pomegranate tree from top to bottom. Since the branches of the pomegranate tree are fragile and spread from bottom to top, it is inconvenient to wrap the nylon bag around the pomegranate tree and may cause damage to the branches. In addition, even if the nylon bag is wrapped and protected from the cold, in heavy snow weather, the large amount of snow accumulated on the nylon bag will crush the small pomegranate trees in the nylon bag, causing damage to the pomegranate trees. SUMMARY

[0003] To make up for the shortcomings of the prior art, the present application provides a pomegranate tree winter anti-freezing protection structure. The ring seat is first wrapped around the main trunk of the pomegranate tree, and then the tightening rope is pulled to drive the multiple sub-shells to turn and gather from bottom to top, so that the branches of the pomegranate tree are gathered inward from the outside under the extrusion of the inner wall of the sub-shell. In the process of installing the protection structure on the pomegranate tree, the branches of the pomegranate tree are maximally protected, and the damage to the branches of the pomegranate tree during the installation of the protection structure is reduced. The conical cover is designed as multiple enclosed sub-shells, which on the one hand facilitates the installation while protecting the branches of the pomegranate tree, and on the other hand, in winter snow weather, the snow is not easy to remain on the conical cover, achieving the protection of the pomegranate tree inside the protection structure from the cold. In addition, the present application ensures its strength while being small and compact, facilitating stacking and transportation.

[0009] Preferably, the two shift blocks near the other end of the arc seat are provided with a wedge-shaped groove on one side close to each other; the wedge-shaped groove passes through the shift block upward, and the wedge-shaped blocks are engaged in the two wedge-shaped grooves; the two wedge blocks are connected by a shift rope.

[0010] Preferably, an avoidance groove is provided inwardly at the lower end of the shift groove; the avoidance groove is fixedly connected to the elastic sheet at the upper end and is fixedly connected to the pressing block at the lower end; the end of the pressing block extends to the outer side of the lower end of the shift groove; the elastic sheet is provided with a first tooth on the side in contact with the shift block; the shift block is provided with a second tooth on the side close to the elastic sheet; the first tooth and the second tooth are unidirectionally engaged.

[0011] Preferably, a reinforcing rod is provided on the inner side of the sub-cover; the reinforcing rod is perpendicular to the inner wall of the sub-cover.

[0012] Preferably, the inner wall of the sub-cover and the reinforcing rod are rotationally connected via a second torsion spring.

[0013] Preferably, the lower surface of the ring seat is provided with a bottom groove staggered from the surrounding edge; the bottom groove is slidably connected to the bottom plate; the upper end of the bottom plate is connected to the bottom of the bottom groove through a second spring.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention puts the ring seat on the trunk of the pomegranate tree in advance, and then pulls the tightening rope to drive the multiple sub-covers to flip and gather from bottom to top, so that the branches on the pomegranate tree are squeezed by the inner wall of the sub-cover and gathered inward from the right outside. Then, during the process of installing the protective structure on the pomegranate tree, the branches on the pomegranate tree are protected to the maximum extent, and the damage of the pomegranate tree branch protection structure during the installation process is reduced; by designing the cone cover into multiple enclosed sub-covers, on the one hand, it is easy to install while protecting the branches of the pomegranate tree, and on the other hand, in snowy weather in winter, snow is not easily left on the cone cover, thereby achieving cold protection and protection for the pomegranate tree inside the protective structure. In addition, the present invention ensures its own strength while having a compact structure, which is convenient for stacking and transportation.

[0016] 2. The present invention controls the other ends of the two arc seats to rotate around one end, so that the other ends of the arc seats are staggered to form a tree-covering gap. The arc edges will be staggered as the arc seats are staggered, and half of the sub-covers will move with the movement of the arc seats. When the tree-covering gap is formed, it is only necessary to control the tree-covering gap space to be larger than the main trunk of the pomegranate tree, so that the ring seat can be directly covered on the main trunk, abandoning the original method of covering the pomegranate tree from top to bottom, reducing the difficulty of covering the ring seat on the pomegranate tree, facilitating the operation and use of the protection structure, and avoiding damage to the branches of the pomegranate tree during the process of covering the tree with the ring seat.

[0017] 3. The present invention pulls all the tightening ropes, and the upper ends of all the sub-covers will move closer to each other and gather toward the center under the pulling of the tightening ropes. The gaps between adjacent sub-covers will be reduced, and the tension spring will pull the unlocked shifting blocks to slide upward along the shifting grooves. The upward movement of the two shifting blocks will drive the shifting ropes to move upward. During the upward movement of the shifting ropes, the pomegranate tree branches stuck in the gaps between adjacent sub-covers can be shifted inwards, avoiding the situation where the gaps between adjacent sub-covers are difficult to tighten due to the obstruction of the pomegranate tree branches. By removing the pomegranate tree branches in the gaps between adjacent sub-covers, the step of manually shifting the branches is eliminated, thereby improving the efficiency and convenience of installing the protective structure on the pomegranate tree.

[0018] 4. In the process of pulling the tightening rope, the present invention causes all the sub-covers to gather inward and tighten near the upper end, and the sub-covers will drive the inner reinforcing rods to be inserted into the branches of the pomegranate tree. After all the sub-covers are tightened to form a cone cover, all the tightening ropes are tied together to complete the installation of the protective structure outside the pomegranate tree. During the use of the protective structure, since the reinforcing rods are inserted into the branches of the pomegranate tree, the cone cover is not easily displaced or detached during the process of protecting the inner pomegranate tree, thereby improving the stability of the protective structure during use.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] First, if Figure 11-12 As shown, in the prior art, winter protection for pomegranate trees can be summarized as a "five-layer" wrapping method. The main reason is that potted pomegranates have less soil in the pots and are more susceptible to freezing in large fields or open fields in the north. Winter cold protection is very important. In the areas north of the Huaihe River and the Qinling Mountains, because pomegranate pots are planted outdoors or in the open air, single-layer protection is particularly important.

[0035] The specific steps of the "five-layer" wrapping method are as follows: First, wrap the trunk with a layer of plastic wrap, and the standard for wrapping the trunk is to wrap the trunk completely as much as possible; second, wrap the trunk with a thermal blanket; third, wrap another layer of plastic wrap around the trunk, wrapping it tightly to prevent rain and snow from entering through the gaps; fourth, wrap the potting soil completely with a large thermal blanket; fifth, wrap the potting soil completely again with a clinker film and tie it tightly with a rope. The following spring, the thermal insulation material can be removed. The present invention, like the existing technology, can also provide winter protection for pomegranate trees. The details are as follows:

[0036] like Figures 1 to 10 As shown, the present invention includes the following embodiments:

[0037] Example 1: Unlike the prior art, the present invention can provide comprehensive protection for smaller pomegranate trees in winter. Specifically, it is a winter antifreeze protection structure for pomegranate trees, including a ring seat 1 and a cone cover 2 on the ring seat 1; the cone cover 2 is conical in shape, and the interior is hollow and passes through the lower end; the diameter of the lower end of the cone cover 2 is smaller than the diameter of the outer edge of the ring seat 1; the cone cover 2 is enclosed by a plurality of sub-covers 21 of uniform specifications; sealing strips (not shown in the figure) are provided at the contact positions of adjacent sub-covers 21 to achieve contact sealing after enclosure; the outer wall of the upper end of the sub-cover 21 is fixedly connected to the tightening rope 22, and the lower end is hinged to the upper surface of the ring seat 1 through a first torsion spring 23; the protection structure can be stacked on each other.

[0038] In this embodiment, the upper surface of the ring seat 1 is fixedly connected to a surrounding edge 11 ; the surrounding edge 11 is arranged close to the outer edge of the ring seat 1 .

[0039] During transportation, after the tightening ropes 22 at the upper ends of the multiple sub-covers 21 are tied together, the protective structures are nested with each other, and the cone cover 2 on the protective structure at the lower position is located inside the cone cover 2 on the protective structure at the upper position, which is convenient for transportation and saves transportation space; when the protective structure is put into use, the protective structure at the upper position is removed from the protective structure at the lower position, and the tightening ropes 22 at the upper ends of the sub-covers 21 are untied, so that the tightening ropes 22 at the upper ends of the multiple sub-covers 21 are untied, and then the first torsion spring 23 will drive the upper ends of the sub-covers 21 to flip outward, and the sub-covers The lower end of 21 will rotate around the corresponding first torsion spring 23, and the upper ends of multiple sub-covers 21 will move away from each other, so that all the sub-covers 21 expand outward. When all the sub-covers 21 are expanded outward, the ring seat 1 is easier to be put on the pomegranate tree. After the ring seat 1 is put on the pomegranate tree, it falls on the ground soil. Then, after stepping on the outer edge of the ring seat 1 with your feet, the tightening ropes 22 at the upper ends of the multiple sub-covers 21 are pulled. After the collection ropes are pulled, the upper ends of all the sub-covers 21 are driven to move closer to each other. The collection ropes will pull the sub-covers 21 to overcome the torsion of the first torsion spring 23 and flip over. The inner sides of the sub-covers 21 are pulled from the bottom The branches of the pomegranate tree are pushed upward, so that the branches of the pomegranate tree diverging from the bottom to the top will be tightened toward the center, and finally the connected sub-covers 21 are contacted and sealed by sealing strips (not shown in the figure) to ensure the sealing of the inner side of the cone cover 2. After all the sub-covers 21 are turned upward, a cone cover 2 will be formed. Then, after the tightening ropes 22 at the upper ends of all the sub-covers 21 are tied together, the anti-freeze protection work of the pomegranate tree is completed. In heavy snow weather in winter, since the cone cover 2 cooperates with the ring seat 1 to cover the pomegranate tree as a whole, the cone cover 2 can keep the pomegranate tree inside warm and cold-proof. In order to further improve the cold-proof effect, the cone cover 2 can be The inside of the cover 2 is filled with heat-insulating material (not shown in the figure). Since the cone cover 2 is conical in shape, snow is not easy to remain on the cone-shaped cone cover 2. Even if it remains, the cone cover 2 can easily support the snow due to its own conical strength. The snow or rain will fall along the outer surface of the cone cover 2 on the upper surface of the ring seat 1. The snow and rain on the upper surface of the ring seat 1 will be intercepted and collected by the surrounding edge 11, so that the ring seat 1 is pressed tightly, making the gravity at the lower position of the protection structure greater, thereby making the protection structure more stable. After winter, the protection structure on the pomegranate tree can be removed by simply lifting the protection mechanism upwards.

[0040] The present invention preliminarily places the ring seat 1 on the trunk of the pomegranate tree, and then pulls the tightening rope 22 to drive the multiple sub-covers 21 to flip and gather from bottom to top, so that the branches on the pomegranate tree are squeezed by the inner walls of the sub-covers 21 and gathered inward from the right side. In the process of installing the protective structure on the pomegranate tree, the branches on the pomegranate tree are protected to the maximum extent, and damage to the pomegranate tree branch protection structure during the installation process is reduced;

[0041] The present invention designs the cone cover 2 into a plurality of enclosed sub-covers 21, so that on the one hand, it is easy to install while protecting the branches of the pomegranate tree. On the other hand, in snowy weather in winter, snow is not easily left on the cone cover 2, thereby achieving cold protection for the pomegranate tree inside the protective structure. In addition, the present invention ensures its own strength while having a compact structure, which is convenient for stacking and transportation.

[0042] Example 2: The ring seat 1 is composed of two arc seats 12 of equal specifications; one end of the two arc seats 12 is rotatably connected and the other end is in movable contact; the surrounding edge 11 is composed of two arc edges 111 of equal specifications; the two surrounding edges 11 are fixedly connected to the upper surface of the corresponding arc seat 12.

[0043] In this embodiment, a card slot 121 is provided at the other end of one of the arc seats 12; a first slide groove 122 is provided at the other end of the other arc seat 12; a first slider 123 is slidably connected in the first slide groove 122; the first slider 123 is connected to the bottom of the first slide groove 122 through a first spring 124; a second slide groove 125 is provided through the first slide groove 122 toward the outside; a second slider 126 is slidably connected in the second slide groove 125; the second slider 126 is fixedly connected to the first slider 123; the end of the first slider 123 away from the first spring 124 can be snapped into the card slot 121.

[0044] After the multiple tightening ropes 22 are unwound, the sub-cover 21 will flip outward and open under the action of the corresponding first torsion spring 23, and then the second slider 126 will be toggled to slide along the second slide groove 125. The second slider 126 will drive the first slider 123 to slide along the first slide groove 122 when being toggled. When the first slider 123 is toggled, it will overcome the elastic force of the first spring 124, and the first slider 123 will be pulled out of the card slot 121 away from the first spring 124, thereby unlocking the other ends of the two arc seats 12. Then, the other ends of the two arc seats 12 are controlled to rotate around one end, so that the other ends of the arc seats 12 are staggered to form a tree gap. The arc edge 111 will be staggered as the arc seat 12 is staggered, and half of the sub-covers 21 will move with the movement of the arc seat 12. When the tree gap is formed, it is only necessary to control the tree gap space to be larger than The main trunk of the pomegranate tree can directly put the ring seat 1 on the main trunk, abandoning the original ring seat 1 being put on the pomegranate tree from top to bottom, reducing the difficulty of putting the ring seat 1 on the pomegranate tree, facilitating the operation and use of the protective structure, and avoiding damage to the branches of the pomegranate tree during the ring seat 1 being put on the tree; after completing the installation of the ring seat 1, the other ends of the control arc seats 12 are close to and aligned with each other, and the second slider 126 is released. The first spring 124 will push the first slider 123 to slide along the first slide groove 122, and the second slider 126 will move with the movement of the first slider 123. The end of the first slider 123 away from the first spring 124 will extend out of the first slide groove 122 and be stuck in the slot 121, thereby locking the other ends of the two arc seats 12. After the two arc seats 12 return to their positions, the ring seat 1 is re-formed, and the two arc edges 111 return to their positions and re-form the annular surrounding edge 11.

[0045] Example 3: A shift groove 24 is provided on the contacting side of the sub-covers 21; a shift block 3 is slidably connected in the shift groove 24; the upper surface of the shift block 3 and the upper end of the shift groove 24 are connected by a tension spring 31; the tension of the tension spring 31 is less than the torsion of the first torsion spring 23; two adjacent shift blocks 3 are connected by a shift rope 32.

[0046] In this embodiment, the two shift blocks 3 near the other end of the arc seat 12 are provided with a wedge-shaped groove 33 on one side close to each other; the wedge-shaped groove 33 passes through the shift block 3 upward, and the two wedge-shaped blocks 34 are engaged in the two wedge-shaped grooves 33; the two wedge-shaped blocks 34 are connected by a shift rope 32; the depth of the shift block 3 is less than the depth of the shift groove 24, and the shift rope 32 can enter the shift groove 24 for avoidance; elastic protrusions (not shown in the figure) can be embedded on the outer wall of the wedge block 34 to increase friction.

[0047] In this embodiment, an avoidance groove 25 is provided inward at the lower end of the shifting groove 24; the avoidance groove 25 is fixedly connected to the elastic sheet 4 at the upper end and fixedly connected to the pressing block 42 at the lower end; the end of the pressing block 42 extends to the outer side of the lower end of the shifting groove 24; the elastic sheet 4 is provided with a first tooth 41 on the side in contact with the shifting block 3; the shifting block 3 is provided with a second tooth 35 on the side close to the elastic sheet 4; the first tooth 41 and the second tooth 35 are unidirectionally engaged.

[0048] After the tightening rope 22 at the upper end of the sub-cover 21 is untied, the first torsion spring 23 will drive the sub-covers 21 to spread out, and the upper ends of all the sub-covers 21 will move away from each other. The distance between adjacent sub-covers 21 will become larger and larger, and the distance between adjacent sub-covers 21 will decrease from top to bottom. Therefore, in the process of the distance between adjacent sub-covers 21 expanding, the pull rope 32 restricts the two pull blocks 3, so that the pull blocks 3 will overcome the tension of the tension spring 31 and slide from top to bottom along the pull groove 24. The pull spring 31 will be pulled during the downward movement of the pull block 3. When the pull block 3 moves downward to the avoidance groove 25, the second teeth 35 on the pull block 3 will be squeezed. The first tooth 41 on the elastic piece 4, the elastic piece 4 will avoid the avoidance groove 25 when it is pressed, and the first tooth 41 will clamp the second tooth 35 on the dial block 3 during the resetting process of the elastic piece 4, and then the wedge block 34 near the other end of the arc seat 12 is taken out from the wedge groove 33, so that the dial rope 32 near the other end of the arc seat 12 is removed, and then the other end of the arc seat 12 is controlled to stagger to form a tree sleeve gap, so that the ring seat 1 is sleeved on the trunk of the pomegranate tree. After the tree sleeve is completed, the other ends of the two arc seats 12 are controlled to return to contact, and the wedge block 34 is re-stuck in the wedge groove 33, so that the dial near the other end of the arc seat 12 The block 3 is connected again through the toggle rope 32. Then, while stepping on the outer edge of the ring seat 1, all the tightening ropes 22 are pulled. The upper ends of all the sub-covers 21 will approach each other and gather toward the center under the pull of the tightening rope 22. The gaps between adjacent sub-covers 21 will be reduced. When the gaps between adjacent sub-covers 21 are smaller than the length of the toggle rope 32, the pressing blocks 42 at the lower ends of the two relative to the toggle grooves 24 squeeze each other. The pressing blocks 42 are pressed to drive the elastic sheet 4 to move toward the corresponding avoidance groove 25. The elastic sheet 4 drives the first tooth 41 to disengage from the second tooth 35, so that the toggle block 3 and the elastic sheet 4 are unlocked. When the toggle block 3 is unlocked, When the lock is locked, the tension spring 31 will pull the shift block 3 to slide upward along the shift groove 24. During the upward movement of the two shift blocks 3, the shift rope 32 will be driven to move upward. During the upward movement of the shift rope 32, the pomegranate branch stuck in the gap between the adjacent sub-covers 21 can be shifted inward, avoiding the situation where the gap between the adjacent sub-covers 21 is blocked by the pomegranate branch and causing difficulty in tightening. By removing the pomegranate branch in the gap between the adjacent sub-covers 21, the step of manually shifting the branches is omitted, so that the efficiency and convenience of installing the protective structure on the pomegranate tree are improved; after the sub-covers 21 are tightened to form the cone cover 2, all the tightening ropes 22 can be tied together.

[0049] Embodiment 4: A reinforcing rod 5 is provided on the inner side of the sub-cover 21 ; the reinforcing rod 5 is perpendicular to the inner wall of the sub-cover 21 .

[0050] In this embodiment, the inner wall of the sub-cover 21 and the reinforcing rod 5 are rotationally connected via a second torsion spring 51 .

[0051] When the tethering rope 22 is pulled, all the sub-covers 21 are gathered inwardly by the upper end and tightened, and the sub-covers 21 drive the reinforcing rod 5 inside to insert into the branches of the pomegranate tree. After all the sub-covers 21 are tightened to form the cone cover 2, all the tightening ropes 22 are tied together to complete the installation of the protective structure outside the pomegranate tree. During the use of the protective structure, since the reinforcing rod 5 is inserted into the branches of the pomegranate tree, the cone cover 2 is not easy to shift and break away from during the protection of the inner pomegranate tree, thereby improving the stability of the protective structure during use; and when the protective structure needs to be unloaded from the pomegranate tree, it is necessary to separate the sub-covers 21 before the protective structure can be controlled to break away from the pomegranate tree; when multiple protective structures are stacked together, the reinforcing rod 5 is compressed to overcome the torsion spring and rotate and bend inside the sub-cover 21 to ensure that multiple protective structures can be stacked and set together, reducing transportation space.

[0052] Embodiment 5: The lower surface of the ring seat 1 is provided with a bottom groove 13 staggered from the surrounding edge 11; the bottom groove 13 is slidably connected to a bottom plate 14; the upper end of the bottom plate 14 is connected to the bottom of the bottom groove 13 via a second spring 15.

[0053] During use of the protective structure, the bottom plate 14 provided on the lower surface of the ring seat 1 in the protective structure rests on uneven soil under the elastic force of the second spring 15, thereby providing a supporting force for the ring seat 1, making the placement of the ring seat 1 more stable and suitable for uneven soil. In addition, multiple bottom plates 14 form a ring to improve the sealing between the lower surface of the ring seat 1 and the soil, and prevent air leakage at the bottom of the ring seat 1 from affecting the thermal insulation effect of the inner side of the sub-cover 21; during transportation, when multiple protective structures are stacked, the bottom plates 14 and the surrounding edges 11 are staggered, and the bottom plate 14 on the ring seat 1 in the upper position rests on the upper surface of the ring seat 1 in the lower position under the elastic force of the second spring 15. In the case of bumpy roads, the ring seats 1 in the upper and lower positions will form a buffer due to the action of the second spring 15, reducing collision damage to adjacent protective structures.
