Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural antifreeze technology, and in particular to a device for protecting citrus trees from frost damage in winter. Background Technology
[0002] Citrus fruits belong to the Rutaceae family and the Citrus genus. They prefer warm and humid climates and are slightly more cold-hardy than pomelos, sour oranges, and sweet oranges. The Citrus subfamily of the Rutaceae family is distributed between 16° and 37° north latitude. They are tropical and subtropical evergreen fruit trees (except for trifoliate orange), and three genera are used for economic cultivation: Trifoliate orange, Citrus, and Citrus.
[0003] Citrus fruits range in flavor from sweet to sour. They can be eaten raw after peeling or juiced. The thick, bitter peel is usually not eaten, but it can sometimes be used as a garnish or processed into animal feed. The outermost layer of the peel can be processed into "orange peel," used in cooking to enhance the flavor of dishes. The peel of citrus fruits, known as "dried tangerine peel," is used to regulate qi, resolve phlegm, and soothe the stomach; the kernels and leaves can promote blood circulation, disperse stagnation, and reduce swelling; the seed oil can be used to make soap and lubricant.
[0004] During the citrus cultivation process, citrus trees will go dormant or stop growing when the surrounding temperature is low or during winter. When the temperature drops to a level that damages or even kills the vegetative organs (leaves, branches, trunk, etc.) or reproductive organs (fruit), frost damage occurs. Therefore, frost prevention has become an important task in citrus tree cultivation.
[0005] A search revealed Chinese patent publication number CN217389544U, which discloses a winter frost protection device for citrus trees. The device includes a support rod, a top support frame, a rotating wheel assembly, and a canopy. The support rod is vertically positioned. The top support frame is installed on top of the support rod and includes a circular support base and several telescopic rods mounted on the circular support base. The telescopic rods are arranged circumferentially around the circular support base and extend downwards at an angle to form an umbrella-like structure. The rotating wheel assembly is installed on the support rod and connects to the telescopic rods to control their extension and retraction. The canopy is laid on the top support frame and extends downwards to contact the ground, forming a frost-protected space for the citrus tree. After use, this frost-protected device uses the rotating wheel assembly to reduce the space of the umbrella-like structure, saving storage space. The citrus tree is located within the frost-protected space, where the internal temperature is relatively higher than the external temperature, preventing frost damage. However, the support rod device in the aforementioned patent has the following drawback: when the device is raised, the support rod may get stuck in the middle of the trunk, potentially causing damage. The equipment is too large and is very difficult to deploy and recycle due to the influence of tree trunks and branches. Utility Model Content
[0006] The purpose of this invention is to solve the problems of damage to tree trunks and inconvenience in operation when using existing technologies, and to propose a citrus tree winter frost protection device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A winter frost protection device for citrus trees includes a base, a support rod vertically fixed at the center of the top of the base, a storage box fixedly installed on the top of the base next to the support rod, a curtain assembly installed inside the storage box, and a traction component connected to the curtain assembly installed on the support rod. The traction component can drive the curtain assembly to unfold or retract relative to the base.
[0009] As a preferred technical solution of this application, the bottom of the base is fixedly equipped with a plurality of omnidirectional wheels arranged in a rectangular pattern.
[0010] As a preferred technical solution of this application, the outer wall of the support rod is provided with a moving groove for moving the traction component.
[0011] As a preferred technical solution of this application, the base has a first screw hole inside, the bottom of the support rod has a second screw hole corresponding to the first screw hole, and a fixing bolt is provided between the support rod and the base.
[0012] As a preferred technical solution of this application, the storage box has a storage slot inside for installing the curtain assembly.
[0013] As a preferred technical solution of this application, the curtain assembly includes side curtains at both ends and a top curtain disposed between the side curtains at both ends.
[0014] As a preferred technical solution of this application, the traction component includes a fixed block, a movable column disposed at one end of the fixed block near the support rod, and a fixing groove opened at the bottom of the fixed block for installing the fixed curtain component, wherein the movable column and the movable groove are used in conjunction.
[0015] As a preferred technical solution of this application, both the base and the fixing block are U-shaped, and the length of the fixing block is half that of the base.
[0016] Compared with the prior art, this utility model provides a citrus tree winter frost protection device, which has the following beneficial effects:
[0017] 1. This citrus tree winter frost protection device utilizes a U-shaped base and fixing block. During use, the traction component first lifts the curtain assembly along a support rod from one side. Once the curtain assembly reaches the top of the support rod, the traction component flips along the rod, turning the curtain assembly from one side to the other, and then returns to the top of the base on the other side. This allows the curtain assembly to be distributed along the top of the base, thus protecting the citrus tree inside the curtain assembly without harming it. The fixing block is half the length of the base, allowing it to match the base during unfolding, solving the problem of existing technologies easily damaging the tree trunk.
[0018] 2. This citrus tree winter frost protection device consists of a storage box, storage slot, curtain assembly, side curtains, top curtain, and fixing blocks. The movement of the fixing blocks moves and unfolds the curtain assembly. After the curtain assembly is fully unfolded, the top curtain, which is relatively stiff, can cover the citrus tree and open the side curtains at both ends. The side curtains, which are relatively soft, can hang down naturally. When retracting, the movement of the fixing blocks can move the curtain assembly to fold up and retract the side curtains and top curtain, and then recycle them in the storage slot of the storage box. This solves the problem of inconvenient operation of tarpaulins in the existing technology. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0028] Example:
[0029] Reference Figure 1 , Figure 2 , Figure 3 A winter frost protection device for citrus trees includes a base 10. A support rod 20 is vertically fixed at the center of the top of the base 10. A storage box 30 is fixedly installed on the top of the base 10 next to the support rod 20. A curtain assembly 40 is installed inside the storage box 30. A traction component connected to the curtain assembly 40 is installed on the support rod 20. The traction component can drive the curtain assembly 40 to unfold or retract relative to the base 10. In use, the base 10 is moved to the designated working position. The traction component first lifts the curtain assembly along the support rod 20 from one side. When the curtain assembly moves to the top of the support rod 20, the traction component flips along the support rod 20 to flip the curtain assembly from one side to the other side, and the traction component falls back to the top of the base on the other side. Thus, the curtain assembly is distributed along the top of the base. Therefore, the citrus tree can be protected inside the curtain assembly 40 without damaging the citrus tree, and the curtain assembly 40 can be unfolded and retracted quickly and conveniently.
[0030] Reference Figure 1 A citrus tree winter frost protection device is further provided, with multiple rectangular casters 110 fixedly installed on the bottom of the base 10. The casters 110 can move the base 10 to different positions, thus facilitating the movement of the device.
[0031] Reference Figure 4 A citrus tree winter frost protection device is further provided with a moving groove 210 on the outer wall of the support rod 20 for moving the traction component. In use, the traction component can move on the moving groove 210 to unfold the curtain component 40 on the top of the citrus tree.
[0032] Reference Figure 3 , Figure 6 A citrus tree winter frost protection device is further provided, wherein the base 10 has a first screw hole 120 inside, and the bottom of the support rod 20 has a second screw hole 220 corresponding to the first screw hole 120. A fixing bolt 230 is provided between the support rod 20 and the base 10, and the support rod 20 can be vertically fixed to the top of the base 10 by fixing the bolt 230, so that the traction component can move on the support rod 20.
[0033] Reference Figure 3 A citrus tree winter frost protection device is further provided with a storage slot 310 inside the storage box 30 for installing the curtain assembly 40. The bottom end of the curtain assembly can be fixed in the storage slot 310. When the traction component drives the curtain assembly to move along the support rod 20, the curtain assembly unfolds and covers the outside of the citrus tree. When it is recycled, the curtain assembly 40 can also be stored in the storage slot 310 under the drive of the traction component, which facilitates the reuse of the device after recycling.
[0034] Reference Figure 2 A citrus tree winter frost protection device is further described, wherein the curtain assembly 40 includes side curtains 410 at both ends and a top curtain 420 disposed between the side curtains 410 at both ends. It should be noted that the material of the top curtain 420 is harder than that of the side curtains 410. When the curtain assembly 40 is unfolded, the harder top curtain 420 can cover the citrus tree and open the side curtains 410 at both ends. The side curtains 410 are softer and can hang down naturally, thereby protecting the citrus tree inside the curtain assembly 40.
[0035] Reference Figure 3 , Figure 6 A citrus tree winter frost protection device is further described, in which the traction component includes a fixed block 50, a movable column 510 disposed at one end of the fixed block 50 near the support rod 20, and a fixing groove 520 opened at the bottom of the fixed block 50 for installing and fixing the curtain assembly 40. The movable column 510 and the movable groove 210 are used in conjunction. Specifically, the movable column 510 can move up and down in the movable groove 210 to raise or lower the curtain assembly. At the same time, the movable column 510 can also rotate in the movable groove 210 to flip the curtain assembly from one side of the support rod 20 to the other side.
[0036] Reference Figure 1 , Figure 5A citrus tree winter frost protection device is further developed, wherein both the base 10 and the fixing block 50 are U-shaped, and the length of the fixing block 50 is half that of the base 10. This U-shaped base 10 and fixing block 50 can protect the citrus tree inside the curtain assembly 40 without harming it. The fixing block 50, being half the length of the base 10, can match the base 10 when unfolded, preventing cold air from entering the interior.
[0037] Specifically, when this utility model is in operation / use: First, the base 10 is moved to the citrus tree using the casters 110. Because the fixing block 50 is installed in the moving groove 210 on the outer wall of the support rod 20 via the moving column 510, the fixing block 50 can move freely on the support rod 20. The movement of the fixing block 50 drives the curtain assembly 40 to move and unfold. After the curtain assembly 40 is fully unfolded, the top curtain 420, which is relatively hard, can cover the citrus tree and open the side curtains 410 at both ends. The side curtains 410, which are relatively soft, can hang down naturally. When retracting, the movement of the fixing block 50 again drives the curtain assembly 40 to fold up and fold the side curtains 410 and the top curtain 420, and then retracts them into the storage groove 310 of the storage box 30. Therefore, the citrus tree can be protected inside the curtain assembly 40 without damaging it, and the curtain assembly 40 can be unfolded and retracted quickly and conveniently.
