Description

Technical Field

[0001] This utility model relates to the field of fruit tree frost damage prevention and control technology, specifically a device for preventing and controlling low-temperature frost damage during the flowering period of fruit trees. Background Technology

[0002] A device for preventing and controlling low-temperature freezing damage during the flowering period of fruit trees has several significant advantages. Fruit tree planting refers to the artificial cultivation and management process of woody or perennial herbaceous plants with fruit as the main harvest target. It covers the entire life cycle, including variety selection, seedling raising, planting, field management, and harvesting. The device for preventing and controlling low-temperature freezing damage during the flowering period of fruit trees is a special agricultural equipment developed to address the vulnerability of fruit trees to frost and low-temperature attacks during the flowering period.

[0003] For example, patent CN223219615U discloses an orchard frost protection device, including a combustion barrel. The upper end of the combustion barrel is equipped with an adjustment component, which includes a U-shaped groove rotatably mounted on the upper end of the combustion barrel. A sliding rod is slidably mounted inside the U-shaped groove, and a vertical rod is fixedly mounted on the upper end of the sliding rod. A connecting rod is rotatably mounted on the inner side of the upper end of the vertical rod, and a blower is fixedly mounted on the left end of the connecting rod. A second screw is fixedly mounted on the upper end of the sliding rod, located to the right of the vertical rod. A groove is formed on the circumferential surface of the right end of the connecting rod, through which the upper end of the second screw passes. An adjustment ring is rotatably mounted on the circumferential surface of the second screw. Under the action of the blower in the adjustment component, the smoke can be directed in the desired direction when it is emitted. Furthermore, the angle of the blower can be adjusted by the adjustment ring, thereby adjusting the height of the smoke flow.

[0004] However, the device lacks a component for filtering the intake air, and the residual dead leaves on the filter component cannot be removed after the fan stops running, thus failing to ensure the cleanliness of the output airflow. In addition, the failure to remove residual dead leaves and other light impurities in a timely manner can cause the air duct to become clogged too quickly. Utility Model Content

[0005] The purpose of this invention is to provide a device for preventing and controlling low-temperature freezing damage during the flowering period of fruit trees, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for preventing and controlling low-temperature freezing damage during the flowering period of fruit trees, including a hollow electric turntable, a column fixedly installed on the rear side of the upper surface of the hollow electric turntable, a filter box fixedly installed on the upper surface of the column, a filter screen plate fitted inside the filter box, multiple sliding grooves opened on the inner side of the column, a receiving plate fitted inside the sliding groove, movable pins provided on the outer surfaces of the filter screen plate and the receiving plate, a first corrugated pipe fixedly installed on the upper surface of the filter box, and an axial flow fan fixedly installed at the other end of the first corrugated pipe.

[0007] According to the above technical solution, an electric rotating shaft is connected and installed on the outer surface of the axial fan, and a support frame is fixedly installed at the other end of the electric rotating shaft.

[0008] According to the above technical solution, a smoke nozzle is fixedly installed on the front side of the axial fan, and a triangular cone is fitted inside the hollow electric turntable.

[0009] According to the above technical solution, the axial fan and the outer surface of the triangular cone are fixedly installed with multiple universal rotary joints, and a second corrugated pipe is connected and installed between the same inner side of the universal rotary joints.

[0010] According to the above technical solution, a smoke generating box is fixedly installed on the lower surface of the triangular pyramid, and a residue box is fixedly installed on the lower surface of the smoke generating box.

[0011] According to the above technical solution, a chassis is fixedly installed on the lower surface of the residue box, and tracks are fixedly installed on the left and right outer surfaces of the chassis.

[0012] According to the above technical solution, a remote control cabinet is fixedly installed on the rear outer surface of the residue box, and a battery cabinet is fixedly installed on the rear outer surface of the remote control cabinet.

[0013] According to the above technical solution, multiple ventilation fans are fixedly installed on the upper surface of the battery cabinet, and bumpers are fixedly installed on the front and rear outer surfaces of the chassis.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: The filter box provides a closed space for the installation of the filter screen, forming a centralized air intake filtration chamber, guiding air from its own interior into the device. The filter screen intercepts impurities such as dead leaves, twigs, and dust in the air, purifying the air entering the device. While preventing impurities from affecting the lifespan of the components, the filtered air also prevents impurities from adhering to the fruit tree flowers, ensuring that pollination is not disturbed. The chute provides a sliding track for the receiving tray, limiting the installation position and movement path of the receiving tray, allowing the receiving tray to be pulled out in a fixed direction. The receiving tray receives the dead leaves and impurities intercepted and fallen by the filter screen, and collects the waste residue left by the filter. When the fan stops running... Afterwards, the fallen leaves will fall into the inside of the receiving tray due to gravity, thus preventing them from remaining on the outer surface of the filter screen and clogging the ventilation duct. Pulling out the receiving tray allows for the removal of any fallen leaves remaining inside. The movable pin fixes the position of the filter screen and the receiving tray, preventing the filter screen from shifting under the impact of airflow and avoiding the receiving tray from slipping due to device movement or vibration. By installing a component for filtering the intake air in this device, and by removing the remaining fallen leaves from the filter component after the fan stops running, clean air output can be ensured. At the same time, the remaining fallen leaves will leave the outer surface of the filter component due to gravity after the fan stops running, and can be quickly removed by using a fallen leaf carrier, preventing the air duct from clogging too quickly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 A device for preventing low-temperature freezing damage to fruit trees during flowering includes a hollow electric turntable 1. A column 2 is fixedly installed on the rear side of the upper surface of the hollow electric turntable 1. A filter box 3 is fixedly installed on the upper surface of the column 2. A filter screen 4 is fitted inside the filter box 3. Multiple grooves 5 are formed on the inner side of the column 2. A receiving plate 6 is fitted inside the grooves 5. Movable pins 7 are provided on the outer surfaces of the filter screen 4 and the receiving plate 6. A first corrugated pipe 8 is fixedly installed on the upper surface of the filter box 3. An axial flow fan 9 is fixedly installed at the other end of the first corrugated pipe 8. The hollow electric turntable 1 is driven by a motor to rotate the components on its upper surface, achieving horizontal control of the device. The hollow area inside the hollow electric turntable 1 provides conditions for the smoke-generating components to pass through. The column 2 is used to control the filter box 3 on its upper surface. The support column 2 provides support, maintaining a certain distance between the filter box 3 and the hollow electric turntable 1, ensuring that air can enter the interior of the filter box 3. The filter box 3 provides a closed space for the installation of the filter screen 4, forming a centralized air intake filtration chamber, guiding air from its own interior into the device. The filter screen 4 intercepts impurities such as dead leaves, twigs, and dust in the air, purifying the air entering the device. While preventing impurities from affecting the lifespan of the components, the filtered air can also prevent impurities from adhering to the fruit tree flowers, ensuring that pollination is not disturbed. The chute 5 provides a sliding track for the receiving tray 6, limiting the installation position and movement path of the receiving tray 6, allowing the receiving tray 6 to be pulled out in a fixed direction. The receiving tray 6 receives the dead leaves and impurities intercepted and fallen by the filter screen, and collects the waste residue left by the filter.

[0019] After the fan stops running, the dead leaves will fall into the inside of the receiving tray 6 due to gravity, thus preventing the dead leaves from remaining on the outer surface of the filter screen 4 and clogging the ventilation duct. The dead leaves remaining in the receiving tray 6 can be cleaned by pulling it out. The movable pin 7 fixes the position of the filter screen 4 and the receiving tray 6 to prevent the filter screen 4 from shifting under the impact of airflow and to prevent the receiving tray 6 from slipping due to device movement and vibration. The first corrugated pipe 8 connects the filter box and the axial flow fan to transmit the filtered air. It is also adapted to the angle adjustment of the axial flow fan and can flexibly deform with the fan rotation. Starting the axial flow fan 9 can provide a strong airflow, which can quickly diffuse smoke or warm air to the fruit trees and flowers, improving the antifreeze efficiency. By installing a component for filtering the intake air in this device, and removing the dead leaves remaining in the filter component after the fan stops running, the cleanliness of the output airflow can be ensured. At the same time, the remaining dead leaves will be removed from the outer surface of the filter component due to gravity after the fan stops running. They can be quickly cleaned by using a dead leaf carrier to prevent the air duct from being blocked too quickly.

[0020] Please see Figure 1 and 4 An electric rotating shaft 10 is connected and installed on the outer surface of the axial fan 9. A support frame 11 is fixedly installed at the other end of the electric rotating shaft 10. The electric rotating shaft 10 drives the axial fan 9 to adjust the angle and change the direction of airflow and smoke injection. The support frame 11 fixes the electric rotating shaft 10 and the axial fan 9, providing a stable support carrier for both and balancing the weight of the axial fan 9.

[0021] Please see Figure 3-5 A smoke nozzle 12 is fixedly installed inside the front of the axial fan 9, and a triangular cone 13 is fitted inside the hollow electric turntable 1. The smoke nozzle 12 sprays out the smoke generated by the smoke generating component, which combines with the airflow of the axial fan 9 to form a smoke barrier. The smoke evenly covers the fruit tree flowers and can stay around the flowers to form an insulation layer to resist low temperature freezing damage. The triangular cone 13 serves as a transfer structure for the smoke, receiving the smoke generated by the smoke generating component and guiding it to the conveying component to ensure the delivery of the smoke.

[0022] Please see Figure 4 Multiple universal rotary joints 14 are fixedly installed on the outer surface of the axial fan 9 and the triangular cone 13. A second corrugated pipe 15 is connected and installed between the same inner side of the universal rotary joints 14. The universal rotary joints 14 connect the axial fan 9 and the triangular cone 13, adapt to the multi-angle rotation of the axial fan 9, and at the same time ensure the stable delivery of smoke in the second corrugated pipe 15. The second corrugated pipe 15 delivers the smoke generated by the smoke generating component and adapts to the angle pitch and horizontal rotation of the universal rotary joints 14 and the device.

[0023] Please see Figure 1 and 5A smoke box 16 is fixedly installed on the lower surface of the triangular pyramid 13, and a residue box 17 is fixedly installed on the lower surface of the smoke box 16. The interior of the smoke box 16 is used to generate antifreeze smoke. By burning the antifreeze medium, diffuseable smoke is formed to provide antifreeze substances for prevention and control. A perforated plate is provided between the residue box 17 and the smoke box 16 so that the residue box 17 can collect the residue and waste generated after the medium inside the smoke box 16 is burned, thus preventing the residue from scattering.

[0024] Please see Figure 1 , 2 The chassis 18 is fixedly installed on the lower surface of the residue box 17. Tracks 19 are fixedly installed on the outer surfaces of the left and right sides of the chassis 18. The chassis 18 serves as the load-bearing foundation of the entire device, integrates the overall structure of the device, and can distribute the weight of each component. The chassis 18 also houses the power motor that drives the device. Driven by the motor inside the chassis 18, the tracks 19 move the device within the orchard, adapting to the complex terrain of the orchard, which is muddy and has field ridges.

[0025] Please see Figure 2 and 5 A remote control cabinet 20 is fixedly installed on the rear outer surface of the residue bin 17. A battery cabinet 21 is fixedly installed on the rear outer surface of the remote control cabinet 20. The electrical components inside the remote control cabinet 20 centrally control the operation of each component of the device and receive the operation signals of each component to realize remote operation. The battery cabinet 21 is used to store electrical energy and provide a stable power supply for all electric components of the device, which is suitable for orchards without fixed power supply. The outer surface of the battery cabinet 21 includes ventilation grilles to provide heat dissipation for the equipment inside the battery cabinet 21.

[0026] Please see Figure 2 and 5 Multiple ventilation fans 22 are fixedly installed on the upper surface of the battery cabinet 21, and bumpers 23 are fixedly installed on the outer surfaces of the front and rear sides of the chassis 18. The ventilation fans 22 provide power for the heat dissipation of the battery cabinet 21, dissipate the heat generated during battery operation, and reduce the internal temperature of the battery cabinet 21. The bumpers 23 protect the chassis 18 and the components on the front and rear sides of the device, and buffer the collision force with obstacles such as tree trunks and stones when the device moves.
