Description

Technical Field

[0001] This invention relates to the field of fruit tree protection technology, and in particular to a frost protection device for fruit trees in response to late spring frost. Background Technology

[0002] Frost is a relatively common agricultural meteorological disaster, referring to a sudden drop in air temperature, with the ground temperature plummeting below 0°C, causing damage to crops and even death. Frost can occur in autumn, winter, and spring. It differs from frost, which is white ice crystals formed by the direct sublimation of water vapor in the near-ground air when the ground temperature is below 0°C. The presence of frost does not necessarily indicate the presence of frost.

[0003] In cold weather, the branches and trunks of fruit trees are exposed on the outside, which can easily lead to the death of the fruit trees. Therefore, it is necessary to protect fruit trees from the cold. Existing frost protection structures for fruit trees usually use a single cotton material to wrap the trunk, which has poor frost protection effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies in terms of poor frost protection, and to propose a frost protection device for fruit trees in response to late spring frosts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a frost protection device for fruit trees in the event of late spring cold snaps, comprising a first arc-shaped plate, with insert plates connected to both sides of the first arc-shaped plate. Each insert plate is connected to a fixing bracket, and each fixing bracket is connected to a screw. One end of each screw is connected to an insert plate. A second arc-shaped plate connects between the two fixing brackets and mates with the first arc-shaped plate. A groove is formed on the side of the second arc-shaped plate opposite to the first arc-shaped plate. A first spring is connected to both sides inside each groove. One end of each first spring is connected to a perforated plate. An elastic pad is connected to the side of each perforated plate away from the first spring, and an elastic pad is connected to the side of each elastic pad away from the perforated plate. The device includes an insulation pad. Each of the grooves is connected to a heating mechanism located between the two first springs. The two heating mechanisms are connected by wires. A power supply box is connected to the side of the first arc-shaped plate away from the second arc-shaped plate. A first wire hole is formed on the first arc-shaped plate, connecting to the power supply box. A sealing plate is connected to the power supply box, and a switch is connected to the power supply box. A battery is connected inside the power supply box. A second wire hole is formed on the first arc-shaped plate, connecting to the groove. A third wire hole is formed on the second arc-shaped plate, on the side of the second wire hole, connecting to the groove. The battery is connected to the heating mechanism via wires.

[0007] Preferably, the heating mechanism includes two parallel fixed plates, one side of each fixed plate is connected to the groove, each fixed plate has a plurality of through holes along the arc direction, each through hole is connected to a heating wire, each through hole is connected to a sealing ring, and each heating wire passes through the sealing ring.

[0008] Preferably, each of the fixing plates is connected to an anti-collision pad on the side away from the groove, and a gap is provided between each anti-collision pad and the perforated plate.

[0009] Preferably, a connecting rod is connected to the opposite side of the first arc-shaped plate and the second arc-shaped plate, and a threaded section is connected to the bottom end of each connecting rod. A hollow column is threaded onto each threaded section, and a pointed block is connected to the bottom end of each hollow column.

[0010] Preferably, each of the hollow columns has a handle connected to its upper ends on both sides, and each handle is fitted with an anti-slip sleeve.

[0011] Preferably, a fixing strip is connected to the upper ends of both sides of the first arc-shaped plate and the second arc-shaped plate, and to the opposite side. Each fixing strip has a guide groove at its upper end, and a sliding groove is formed on both sides of each guide groove. A slider is slidably connected between every two sliding grooves. A second spring is connected to the side of each guide groove away from the slider. One end of each second spring is connected to the slider. A support rod is connected to the upper end of each slider. A clamping block is connected to the upper end of each support rod. Two clamping blocks cooperate with each other. A sealing gasket is connected to the opposite side of each clamping block. A baffle is connected to each support rod above the fixing strip, and the baffle covers the fixing strip.

[0012] The frost protection device for fruit trees in response to late spring frost proposed in this invention has the following advantages:

[0013] When the perforated plate is clamped between the first and second arc-shaped plates on both sides of the fruit tree branch, it comes into contact with the branch. The perforated plate compresses the first spring, which generates elastic force. The elastic force of the first spring compresses the perforated plate, making it tightly contact the branch. The perforated plate compresses the elastic pad, which in turn compresses the insulation pad, making the insulation pad adhere tightly to the outside of the branch, wrapping the branch and effectively preventing frost from contacting it. This provides good insulation and frost protection. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-7 A frost protection device for fruit trees in response to late spring cold snaps includes a first arc-shaped plate 1, with insert plates 2 connected to both sides of the first arc-shaped plate 1. Each insert plate 2 is connected to a fixing frame 3, and each fixing frame 3 is connected to a screw 4. One end of each screw 4 is connected to an insert plate 2. A second arc-shaped plate 5 is connected between the two fixing frames 3. The second arc-shaped plate 5 cooperates with the first arc-shaped plate 1. The first arc-shaped plate 1 and the second arc-shaped plate 5 are clamped on both sides of the fruit tree branch. The insert plates 2 are inserted into the fixing frames 3, so that the first arc-shaped plate 1 and the second arc-shaped plate 5 move simultaneously. The screws 4 are manually turned to fix the first arc-shaped plate 1 and the second arc-shaped plate 5 together.

[0025] The second arc-shaped plate 5 and the first arc-shaped plate 1 each have a groove 6 on their opposite sides. Each groove 6 has a first spring 7 connected to both sides. Each first spring 7 has a perforated plate 8 connected to one end. Each perforated plate 8 has an elastic pad 9 connected to the side away from the first spring 7. Each elastic pad 9 has an insulation pad 10 connected to the side away from the perforated plate 8. Each groove 6 has a heating mechanism connected between the two first springs 7. The two heating mechanisms are connected by a wire. When the first arc-shaped plate 1 and the second arc-shaped plate 5 are clamped on both sides of the fruit tree branch, the perforated plate 8 contacts the branch. The perforated plate 8 compresses the first spring 7. The first spring 7 generates elastic force after being compressed. The elastic force generated by the first spring 7 compresses the perforated plate 8, making the perforated plate 8 in close contact with the branch. The perforated plate 8 compresses the elastic pad 9. The elastic pad 9 compresses the insulation pad 10, making the insulation pad 10 stick tightly to the outside of the branch, wrapping the branch and effectively preventing frost from contacting the branch, thus achieving a heat preservation effect.

[0026] A power supply box 15 is connected to the side of the first arc-shaped plate 1 away from the second arc-shaped plate 5. A first wire hole 17 is provided on the first arc-shaped plate 1, connecting to the power supply box 15. A sealing plate 16 is connected to the power supply box 15, and a switch 19 is connected to it. A battery block 18 is connected inside the power supply box 15. A second wire hole 20 is provided on the first arc-shaped plate 1, connecting to a groove 6. A third wire hole 21 is provided on the second arc-shaped plate 5, located to the side of the second wire hole 20, connecting to the groove 6. The battery block... 18 is connected to the heating mechanism via wires. The wires between the battery block 18 and the heating mechanism in the first arc plate 1 pass through the first wire hole 17. The wires between the heating mechanism in the first arc plate 1 and the heating mechanism in the second arc plate 5 pass through the second wire hole 20 and the third wire hole 21. The battery block 18 is powered by the switch 19. After the battery block 18 powers the heating mechanism, the heating mechanism raises the temperature of the gas in the groove 6. The hot gas passes through the elastic pad 9 and the heat insulation pad 10 in sequence, and finally comes into contact with the branches to warm the branches and prevent frost from damaging the branches.

[0027] Example 2

[0028] Reference Figure 1-7As another preferred embodiment of the present invention, the difference from embodiment 1 is that the heating mechanism includes two parallel fixed plates 11. Each fixed plate 11 has a groove 6 connected to one side. Each fixed plate 11 has several through holes 12 along the arc direction. Each through hole 12 is connected to a heating wire 13. The heating wires 13 are connected in series and connected to the battery block 18 through wires. Each through hole 12 is connected to a sealing ring 14. Each heating wire 13 passes through the sealing ring 14. Each fixed plate 11 has an anti-collision pad connected to the side away from the groove 6. Each anti-collision pad has a gap with the perforated plate 8. After the heating wire 13 is powered on, it heats the gas and raises the temperature of the gas inside the groove 6. After the perforated plate 8 is squeezed, it contacts the anti-collision pad. The anti-collision pad reduces the collision intensity between the perforated plate 8 and the fixed plate 11.

[0029] Example 3

[0030] Reference Figure 1-7 In another preferred embodiment of the present invention, based on embodiment 1, connecting rods 22 are connected to the opposite sides of the first arc-shaped plate 1 and the second arc-shaped plate 5. Each connecting rod 22 has a threaded section 23 at its bottom end, and a hollow column 24 is threaded onto each threaded section 23. A pointed block 25 is connected to the bottom end of each hollow column 24, and handles 26 are connected to the upper ends of both sides of each hollow column 24. An anti-slip sleeve 27 is fitted onto each handle 26. The first arc-shaped plate 1 and the second arc-shaped plate 5 are then installed... After fixing, manually turn the handle 26. The handle 26 drives the hollow column 24 to rotate in the opposite direction. The hollow column 24 drives the tip block 25 to rotate. After the hollow column 24 rotates, there is a relative displacement between it and the threaded section 23, which drives the tip block 25 to move downward, so that the tip block 25 inserts into the ground. After the tip block 25 inserts into the ground, it fixes the hollow column 24, thereby fixing the connecting rod 22. The connecting rod 22 supports the first arc plate 1 and the second arc plate 5 to prevent the first arc plate 1 and the second arc plate 5 on the branch from falling downward.

[0031] Example 4

[0032] Reference Figure 1-7As another preferred embodiment of the present invention, the difference from embodiment 1 is that fixing strips 28 are connected to the upper ends and opposite sides of both sides of the first arc plate 1 and the second arc plate 5. Each fixing strip 28 has a guide groove 29 at its upper end, and sliding grooves are formed on both sides of each guide groove 29. A slider 30 is slidably connected between every two sliding grooves. A second spring 34 is connected to the side of each guide groove 29 away from the slider 30. One end of each second spring 34 is connected to the slider 30. A support rod 31 is connected to the upper end of each slider 30. A clamping block 32 is connected to the upper end of each support rod 31. Two clamping blocks 32 cooperate with each other, and the opposite sides of the two clamping blocks 32 are connected to... Each support rod 31 is equipped with a sealing gasket 33 and a baffle 35 is connected above the fixing strip 28. The baffle 35 covers the fixing strip 28. When the first arc plate 1 and the second arc plate 5 are installed, the branch is located between the two clamping blocks 32. The clamping blocks 32 are pulled outward, and the second spring 34 is compressed. After the first arc plate 1 and the second arc plate 5 are fixed, the sealing gaskets 33 on the two clamping blocks 32 are in contact with the branch. The sealing gaskets 33 seal the branch at the upper end of the first arc plate 1 and the second arc plate 5 to prevent rainwater from falling into the first arc plate 1 and the second arc plate 5. At the same time, the baffle 35 covers the fixing strip 28 to prevent debris from falling into the guide groove 29 and affecting the movement of the slider 30.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
