The bottom of the air guide cover is uniformly provided with arc through grooves, and the bottom of the air guide cover is fixedly installed with a bottom guide cover. The multi-directional heat dissipation self-adaptable frost prevention machine for orchard in early spring and low temperature is fixedly installed in an orchard, and after being powered on, a temperature measurer measures the temperature in the orchard. When the environmental temperature reaches -2 DEG C, the frost prevention machine starts to work, and the heating mechanism converts electric power into heat.

Description

Technical Field

[0001] This invention relates to the field of frost prevention machine technology, specifically to a multi-directional heat dissipation adaptive early spring low-temperature frost prevention machine for orchards. Background Technology

[0002] The orchard early spring low temperature frost protection machine is the core equipment for coping with late spring cold and preventing frost damage to fruit tree flower buds. Especially in the process of fruit tree seedling cultivation, frost will affect the survival rate of seedlings. The equipment avoids the damage to northern deciduous fruit trees such as apples and pears caused by low temperature frost by actively disturbing the air and raising the local ambient temperature. For example, a nighttime automatic smoke fumigation and frost protection device for orchards, disclosed in CN111264262B, includes a main base. A bimetallic strip is installed on the upper interior of the main base. A plate is fixedly connected to the bottom of the bimetallic strip. An hourglass is fixedly connected to the front of a second gear, and a strong magnetic plate is placed inside the hourglass. A magnetic block is fixedly connected to the left side of a sliding plate. A friction plate corresponding to an ignition device is fixedly connected to the bottom of a convex plate. A smoke generator is placed on the right side of the main base. An ignition wire connected to the smoke generator is provided on the ignition device. When the nighttime temperature is too low, the bimetallic strip deforms and contracts, driving the first and second gears to rotate via the plate. The convex plate rotates to contact the ignition device. Touching the ignition wire ignites the smoke generator, which then begins to smoke and prevent frost damage. As the hourglass rotates, the strong magnetic plate gradually descends until it aligns with the magnetic block. Pushing the sliding plate opens the valve, allowing water from the tank to flow onto the smoke generator, eliminating the risk of open flame. This function is safe and reliable. However, during use, when the defroster discharges heated air, air tends to accumulate at the discharge point. This causes the heated air to remain and accumulate at the discharge point, gradually decreasing in temperature. Consequently, less heat is transferred to the air at the defrosting point after discharge, affecting the defrosting effect. Additionally, in orchards, the presence of dust particles can easily cause blockages during air intake. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: a multi-directional heat dissipation adaptive orchard early spring low-temperature frost prevention machine, comprising: An air intake mechanism, wherein a heating mechanism is mounted on the top of the air intake mechanism, and a heat dissipation mechanism is mounted on the top of the heating mechanism; A temperature sensor and a controller are provided, wherein the temperature sensor is installed on the top of the heat dissipation mechanism, the controller is installed on the outside of the heating mechanism, and the controller and the temperature sensor are electrically connected. The heat dissipation mechanism includes a heat-conducting cylinder, a top cover plate fixedly installed on the top of the heat-conducting cylinder, and a conical surface with an increasing outer diameter from top to bottom on the outer top of the heat-conducting cylinder. Circular grooves are evenly distributed on the conical surface of the outer side of the heat-conducting cylinder, and air guide pipes are fixedly installed in each of the circular grooves. An air guide shroud is fixedly installed on the bottom of the inner wall of the heat-conducting cylinder, the inner diameter of the air guide shroud gradually increasing from top to bottom, and arc-shaped grooves are evenly distributed on the bottom of the air guide shroud. A bottom guide shroud is fixedly installed on the bottom of the air guide shroud. Through the cooperation of the bottom guide shroud and the air guide shroud, when the heated hot air is discharged, when the hot air... When the air cannot be discharged in time, some of the accumulated air can move downward along the outside of the air guide shroud under the push of air pressure. At the same time, the air guide shroud separates the continuously upward flowing air, allowing some of the accumulated air to pass smoothly through the arc groove of the air guide shroud and flow downward through the gap between the bottom guide shroud and the heat conduction cylinder to re-enter the heating mechanism for heating. This avoids the situation where the internal gas cannot be discharged in time during operation, resulting in a drop in temperature. After being discharged from the equipment, less heat is transferred to the air at the heating position, affecting the anti-frost effect. The bottom guide shroud is located inside the arc groove, and the outer diameter of the bottom guide shroud gradually decreases from top to bottom.

[0004] Preferably, two ring frame seats are fixedly installed on the conical surface of the outer side of the heat-conducting cylinder, and an outer ring frame is rotatably installed between the ring frame seats. An inclined guide plate is fixedly installed on the inner wall of the outer ring frame. The inclined guide plate is evenly installed on the inner wall of the outer ring frame, and the outer ring frame is located outside the air guide pipe. A water receiving tray is fixedly installed on the inner wall of the heat-conducting cylinder. The water receiving tray is located directly below the air guide pipe. The tilt of the top of the water receiving tray cooperates with the conical surface of the bottom of the top cover plate to guide the diffused hot air after it is discharged from the air guide hood, so that it can be discharged smoothly through the air guide pipe. When not working, the water droplets condensed on the inner wall of the air guide pipe drip down and are blocked by the upward arc bend of the water receiving tray to prevent them from dripping into the interior and causing circuit damage. The top of the water receiving tray tilts downward as it moves away from the heat-conducting cylinder, and the side of the water receiving tray away from the heat-conducting cylinder bends upward in an arc. The bottom of the top cover plate is a conical surface with a central protrusion.

[0005] Preferably, the heating mechanism includes a fixed cylinder, the top of which is fixedly connected to the bottom of the heat-conducting cylinder. The inner wall of the fixed cylinder has an annular groove, and a heat-insulating annular gasket is fixedly installed at each annular groove. A gap exists between the outer side of the heat-insulating annular gasket and the inner wall of the fixed cylinder. Through the cooperation of the heat-insulating annular gasket and the fixed cylinder, the heat insulation characteristics of the heat-insulating annular gasket are utilized, while the gap between the heat-insulating annular gasket and the fixed cylinder forms a double-layer shell on the outer side of the heating position, improving the heat insulation effect, limiting heat transfer from the heating position to the outside, and ensuring that the air flowing through the heating position has sufficient heat for absorption. A fixing buckle is fixedly installed on the inner wall of the heat-insulating annular gasket, and the fixing buckle is evenly installed along the center of the heat-insulating annular gasket. An electric heating ring is fixedly installed on the inner wall of the fixing buckle.

[0006] Preferably, the air intake mechanism includes a slotted cylinder with slots evenly distributed on its outer side. A connecting cylinder is fixedly installed at the center of the inner wall of the slotted cylinder. Through slots are evenly distributed on the outer side of the connecting cylinder. Grille arc plates are fixedly installed in the slots of the slotted cylinder. A support ring is fixedly installed on the inner wall of the connecting cylinder. The support ring is located above the through slot of the connecting cylinder. A motor is fixedly installed at the bottom of the support ring. The output end of the motor passes through the support ring and extends above it. An impeller is fixedly installed at the output end of the motor.

[0007] Preferably, a sealing disc is fixedly installed on the top of the outer side of the connecting cylinder. The outer side of the sealing disc is fixedly connected to the top of the inner wall of the hollow cylinder. A support rod is fixedly installed on the top of the inner wall of the connecting cylinder. The support rod is evenly installed along the center of the connecting cylinder. A conical guide cylinder is fixedly installed at the end of the support rod away from the connecting cylinder. The outer diameter of the conical guide cylinder gradually decreases from top to bottom, and a support cylinder is fixedly installed on the top of the conical guide cylinder. Through the cooperation of the conical guide cylinder and the spiral plate of the guide ring, the conical guide cylinder guides the upward flowing air to approach the heating ring, reducing the distance between them. With the guidance of the spiral plate during the upward flow of air, the air spirals upward, increasing the flow area of ​​the air at the heating position, allowing the air to fully absorb the heat generated by the heating ring. A guide ring is fixedly installed on the outer side of the support cylinder, and spiral plates are evenly arranged on the outer side of the guide ring.

[0008] Preferably, an arc-groove cover is fixedly installed on the inner wall of the empty groove cylinder. The inner wall of the arc-groove cover is fixedly connected to the outer side of the connecting cylinder. The connection position of the arc-groove cover and the connecting cylinder is located below the through groove of the connecting cylinder, and the connection position of the arc-groove cover and the empty groove cylinder is located above the empty groove of the empty groove cylinder. Arc grooves are evenly opened on the outer side of the arc-groove cover, and an air filter plate is fixedly installed on the outer side of the arc-groove cover. An inclined guide cover is fixedly installed on the inner wall of the empty groove cylinder. Through the cooperation of the inclined guide cover and the arc-groove cover, when filtering air, the filtered dust particles can be driven by the air flow and move along the inclined side of the air filter plate installed on the outer side of the arc-groove cover. They can then pass through the gap between the inclined guide cover and the arc-groove cover and enter the bottom of the inclined guide cover for storage. At the same time, the inclined guide cover blocks the dust particles stored below, preventing the dust particles from being blown away by the air after entering and causing splashing. The inclined guide cover is located below the empty groove of the empty groove cylinder.

[0009] This invention provides a multi-directional heat dissipation adaptive orchard early spring low-temperature frost protection machine. It has the following beneficial effects: (I) This multi-directional heat dissipation adaptive orchard early spring low temperature frost prevention machine, through the cooperation of the bottom guide cover and the air guide cover, when the heated air cannot be discharged in time, some of the accumulated air can move downward along the outside of the air guide cover under the push of air pressure. At the same time, the air guide cover separates the continuously upward flowing air, allowing some of the accumulated air to pass smoothly through the arc groove of the air guide cover, and flow downward through the gap between the bottom guide cover and the heat conduction cylinder to re-enter the heating mechanism for heating. This avoids the situation where the internal gas cannot be discharged in time during operation, resulting in a decrease in temperature and less heat transferred to the air at the heating position after being discharged from the equipment, which would affect the frost prevention effect.

[0010] (II) This multi-directional heat dissipation adaptive orchard early spring low temperature frost prevention machine, through the cooperation of the inclined top of the water receiving tray and the conical surface at the bottom of the top cover, guides the diffused hot air after the hot air is discharged through the air guide hood, so that it can be smoothly discharged through the air guide pipe. At the same time, when it is not working in the orchard, the water droplets condensed on the inner wall of the air guide pipe are blocked by the upward arc bend of the water receiving tray to prevent them from dripping into the interior and causing circuit damage.

[0011] (III) This multi-directional heat dissipation adaptive orchard early spring low temperature frost prevention machine, through the cooperation of the heat insulation ring pad and the fixed cylinder, utilizes the heat insulation characteristics of the heat insulation ring pad and the gap between the heat insulation ring pad and the fixed cylinder to form a double shell on the outside of the heating position, thereby improving the heat preservation effect, restricting the heat transfer from the heating position to the outside, and ensuring that the air flowing through the heating position has sufficient heat for absorption.

[0012] (iv) This multi-directional heat dissipation adaptive orchard early spring low temperature frost prevention machine uses a conical guide cylinder and a spiral plate of a guide ring to guide the upward flow of air, bringing it closer to the heating ring and reducing the distance between them. The spiral plate guides the air during its upward flow, causing it to spiral upward and increasing the air flow area at the heating position, so that the air can fully absorb the heat generated by the heating ring.

[0013] (v) The multi-directional heat dissipation adaptive orchard early spring low temperature frost prevention machine, through the cooperation of the inclined guide cover and the arc groove cover, allows the filtered dust particles to be driven by the air flow and run along the inclined side of the air filter plate installed on the outside of the arc groove cover, so that they enter the bottom of the inclined guide cover for storage through the gap between the inclined guide cover and the arc groove cover. At the same time, the inclined guide cover blocks the dust particles stored below, preventing the dust particles from being blown away by the air and causing splashing. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] For the first embodiment, please refer to... Figures 1 to 5 The present invention provides a technical solution: A multi-directional heat dissipation adaptive orchard early spring low-temperature frost protection machine, comprising: An air intake mechanism 1 is provided, a heating mechanism 2 is installed on the top of the air intake mechanism 1, and a heat dissipation mechanism 3 is installed on the top of the heating mechanism 2. The thermometer 4 is installed on the top of the heat dissipation mechanism 3, and the controller 5 is installed on the outside of the heating mechanism 2. The controller 5 and the thermometer 4 are electrically connected. The heat dissipation mechanism 3 includes a heat-conducting cylinder 31. A top cover plate 32 is fixedly installed on the top of the heat-conducting cylinder 31. The top of the outer side of the heat-conducting cylinder 31 is a conical surface with an increasing outer diameter from top to bottom. Circular grooves are evenly distributed on the conical surface of the outer side of the heat-conducting cylinder 31, and air guide pipes 36 are fixedly installed in each of the circular grooves. An air guide shroud 38 is fixedly installed on the bottom of the inner wall of the heat-conducting cylinder 31. The inner diameter of the air guide shroud 38 gradually increases from top to bottom. The air heated by the heating mechanism 2 flows upward. The bottom guide shroud 39 cooperates with the air guide shroud 38, using the bottom guide shroud 39 to block the upward-flowing air, causing it to flow upward along the inner wall of the air guide shroud 38. At the same time, the characteristic of the inner diameter of the air guide shroud 38 gradually increasing from top to bottom causes the air to flow upward. During the process, the width of the flow path gradually decreases, the flow rate increases, and the flow impacts the conical surface at the bottom of the top cover plate 32. Then, guided by the conical surface, it diffuses in all directions and is discharged obliquely upward through the air guide pipe 36. The bottom of the air guide shroud 38 is uniformly provided with arc-shaped grooves, and a bottom guide shroud 39 is fixedly installed at the bottom of the air guide shroud 38. After being discharged from the air guide shroud 38, the air that cannot be discharged in time due to the large amount of air accumulation can flow downward through the arc-shaped grooves of the air guide shroud 38 under gas pressure, and re-enter the heating position of the heating mechanism 2 through the gap between the bottom guide shroud 39 and the heat conduction cylinder 31 to absorb heat. The bottom guide shroud 39 is located inside the arc-shaped grooves, and the outer diameter of the bottom guide shroud 39 gradually decreases from top to bottom.

[0018] Two ring frame seats 35 are fixedly installed on the conical surface of the outer side of the heat conduction cylinder 31. An outer ring frame 34 is rotatably installed between the ring frame seats 35. An inclined guide plate 33 is fixedly installed on the inner wall of the outer ring frame 34. The inclined guide plate 33 is evenly installed on the inner wall of the outer ring frame 34 and the outer ring frame 34 is located outside the air guide duct 36. A water receiving tray 37 is fixedly installed on the inner wall of the heat conduction cylinder 31. The water receiving tray 37 is located directly below the air guide duct 36. After the hot air is discharged from the air guide duct 36, it is guided by the inclined guide plate 33 on the inner wall of the outer ring frame 34. During the upward discharge process, the diffusion area is increased. The top of the water receiving tray 37 is inclined downward as it moves away from the heat conduction cylinder 31. The side of the water receiving tray 37 away from the heat conduction cylinder 31 is curved upward. The bottom of the top cover plate 32 is a conical surface with a central protrusion.

[0019] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7As shown, the heating mechanism 2 includes a fixed cylinder 21. The top of the fixed cylinder 21 is fixedly connected to the bottom of the heat-conducting cylinder 31. The inner wall of the fixed cylinder 21 is provided with an annular groove. A heat-insulating ring pad 22 is fixedly installed in each annular groove of the fixed cylinder 21. There is a gap between the outer side of the heat-insulating ring pad 22 and the inner wall of the fixed cylinder 21. A fixing buckle 23 is fixedly installed on the inner wall of the heat-insulating ring pad 22. By energizing the heating ring 24, the heating ring 24 converts electrical energy into heat and transfers it to the flowing air, thus heating the flowing air. At the same time, during the heating process, the heat-insulating ring pad 22 cooperates with the fixed cylinder 21. Utilizing the heat insulation characteristics of the heat-insulating ring pad 22 and the double-layer shell structure formed by the gap between the heat-insulating ring pad 22 and the fixed cylinder 21, the heat transfer to the outside is reduced. The fixing buckle 23 is evenly installed along the center position of the heat-insulating ring pad 22. The heating ring 24 is fixedly installed on the inner wall of the fixing buckle 23.

[0020] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 10 As shown, the air intake mechanism 1 includes a slotted cylinder 101. Slots are evenly distributed on the outer side of the slotted cylinder 101. A connecting cylinder 107 is fixedly installed at the center of the inner wall of the slotted cylinder 101. Through slots are evenly distributed on the outer side of the connecting cylinder 107. A grille arc plate 103 is fixedly installed in each slot of the slotted cylinder 101. A support ring 112 is fixedly installed on the inner wall of the connecting cylinder 107. The support ring 112 is located above the through slot of the connecting cylinder 107. A motor 113 is fixedly installed at the bottom of the support ring 112. The output end of the motor 113 passes through the support ring 112 and extends above it. An impeller 114 is fixedly installed at the output end of the motor 113.

[0021] A sealing disc 102 is fixedly installed on the top of the outer side of the connecting cylinder 107. The outer side of the sealing disc 102 is fixedly connected to the top of the inner wall of the empty groove cylinder 101. A support rod 108 is fixedly installed on the top of the inner wall of the connecting cylinder 107. The support rod 108 is evenly installed along the center position of the connecting cylinder 107. A conical guide cylinder 105 is fixedly installed at the end of the support rod 108 away from the connecting cylinder 107. The outer diameter of the conical guide cylinder 105 gradually decreases from top to bottom. During the upward movement of the air driven by the impeller 114, the air is guided by the conical surface of the conical guide cylinder 105 to move closer to the heating position of the heating mechanism 2. At the same time, after entering the heating position, the air is guided by the spiral plates evenly arranged on the outer side of the guide ring 104 to spiral upward under the guidance of the spiral plates, increasing the flow area of ​​the air at the heating position. A support cylinder 106 is fixedly installed on the top of the conical guide cylinder 105. A guide ring 104 is fixedly installed on the outer side of the support cylinder 106. Spiral plates are evenly arranged on the outer side of the guide ring 104.

[0022] An arc groove cover 109 is fixedly installed on the inner wall of the empty groove cylinder 101. The inner wall of the arc groove cover 109 is fixedly connected to the outer side of the connecting cylinder 107. The connection position between the arc groove cover 109 and the connecting cylinder 107 is located below the through groove of the connecting cylinder 107, and the connection position between the arc groove cover 109 and the empty groove cylinder 101 is located above the empty groove of the empty groove cylinder 101. The impeller 114 is driven to rotate by the motor 113. During the rotation of the impeller 114, the propeller blades of the impeller 114 drive the air inside the connecting cylinder 107 to flow upward rapidly, which reduces the air pressure inside the connecting cylinder 107. Under the influence of atmospheric pressure, the air from outside the equipment passes through the grid arc plate 103 at the empty groove of the empty groove cylinder 101 and enters the interior of the empty groove cylinder 101, and then flows into the arc groove. The air filter plate 110 of the arc groove cover 109 moves in the direction of the air filter plate 110 of the arc groove cover 109 to filter the incoming air. The filtered air passes through the arc groove of the arc groove cover 109 and then enters the interior of the connecting cylinder 107 through the through groove. At the same time, the dust particles filtered out by the air filter plate 110 can move downward along the inclination of the air filter plate 110 under the action of the air flow and enter the gap between the inclined guide cover 111 and the arc groove cover 109 for storage. The arc groove cover 109 has evenly opened arc grooves on its outer side and the air filter plate 110 is fixedly installed on the outer side of the arc groove cover 109. The inclined guide cover 111 is fixedly installed on the inner wall of the empty groove cylinder 101 and is located below the empty groove of the empty groove cylinder 101.

[0023] In the fourth embodiment, based on the first embodiment, the heating mechanism 2 can be replaced with a diesel combustion heating mechanism. The diesel combustion heating mechanism generates heat by burning diesel fuel, which heats the air flowing through it, thereby raising the air temperature.

[0024] In use, the equipment is first installed in the orchard at a height of eight meters. Then, the equipment is powered on, and the temperature in the orchard is measured by the thermometer 4. The temperature data is then transmitted to the controller 5 via an electrical signal. When the ambient temperature reaches -2℃, the frost prevention machine starts working, and the heating mechanism 2 converts electricity into heat. When the ambient temperature reaches 0℃, it stops working, and the controller 5 controls the heating power of the heating mechanism 2. When the temperature is low, the heating power is increased, and when the temperature is high, the heating power is decreased. At the same time, outside air is drawn into the equipment through the air intake mechanism 1 and guided into the interior of the heating mechanism 2. After the air is heated by the heating mechanism 2, it is introduced into the heat dissipation mechanism 3. Finally, the heated air is discharged by the heat dissipation mechanism 3, raising the orchard temperature and performing frost prevention.

[0025] In the air intake mechanism 1, the impeller 114 is driven to rotate by the motor 113. During rotation, the propeller blades of the impeller 114 cause the air inside the connecting cylinder 107 to flow upwards rapidly, reducing the air pressure inside the connecting cylinder 107. Under atmospheric pressure, outside air passes through the grid arc plate 103 at the slot of the empty slot cylinder 101 and enters the interior of the empty slot cylinder 101. It then moves towards the arc slot cover 109, where the air filter plate 110 filters the incoming air. The filtered air passes through the arc slot of the arc slot cover 109 and then through the connecting cylinder. The through groove of 107 enters the interior of the connecting cylinder 107. At the same time, the dust particles filtered out by the air filter plate 110 can move downward along the inclination of the air filter plate 110 under the drive of the air flow and enter the gap between the inclined guide cover 111 and the arc groove cover 109 for storage. Meanwhile, as the impeller 114 drives the air to move upward, the conical surface of the conical guide cylinder 105 guides the air flow and makes it closer to the heating position of the heating mechanism 2. After entering the heating position, the air is guided upward by the spiral plates evenly arranged on the outside of the guide ring 104, increasing the flow area of ​​the air at the heating position.

[0026] In the heating mechanism 2, by energizing the heating ring 24, the heating ring 24 converts electrical energy into heat and transfers it to the flowing air, thus heating the air. At the same time, during the heating process, the heat insulation ring 22 cooperates with the fixed cylinder 21. Utilizing the heat insulation characteristics of the heat insulation ring 22, and the double-layer shell structure formed by the gap between the heat insulation ring 22 and the fixed cylinder 21, the heat transfer to the outside is reduced.

[0027] In the heat dissipation mechanism 3, the air heated by the heating mechanism 2 flows upward. It is blocked by the bottom guide cover 39 and the air guide cover 38. The bottom guide cover 39 blocks the upward airflow, causing it to flow upward along the inner wall of the air guide cover 38. At the same time, the air guide cover 38 gradually increases in diameter from top to bottom, which gradually reduces the width of the flow path and increases the flow velocity as the air flows upward. It impacts the conical surface at the bottom of the top cover plate 32 and then diffuses in all directions under the guidance of the conical surface. It is then diverted upward through the air guide pipe 36 in multiple directions. After the hot air is diverted by the air guide pipe 36, it is guided by the inclined guide plate 33 on the inner wall of the outer ring frame 34. During the diagonal upward diversion, the diffusion area is increased. At the same time, the air that cannot be diverted in time due to the large amount of air accumulation after being diverted by the air guide cover 38 can flow downward along the outer side of the air guide cover 38 under gas pressure, pass through the arc groove of the air guide cover 38, and re-enter the heating position of the heating mechanism 2 through the gap between the bottom guide cover 39 and the heat conduction cylinder 31 for heat absorption.
