Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural planting, in particular to an orchard anti-frost technology, in particular to a side-heating orchard anti-frost device. Background Art

[0002] Spring frost damage in orchards is a major meteorological disaster affecting fruit production in northern China, occurring an average of one to two times per year. Some areas are severely affected, even resulting in widespread crop failure and significant losses. Currently, frost prevention measures in orchards primarily include agronomic, physical, and chemical measures. Agronomic measures include winter tree whitewashing, spring irrigation, antifreeze spraying, and laying mulch or straw. Physical prevention techniques primarily involve air heating and air disturbance, with measures such as fumigation, fires, high-altitude fans in the fields, high-pressure fans at the edge of fields, and drones. Chemical measures include spraying antifreeze before flowering and spraying flower and fruit preserving agents and brassinolide after frost damage occurs. Whitewashing, irrigation, and antifreeze spraying can provide some relief for mild frost damage in orchards. However, when moderate or severe frost damage occurs, the orchard temperature drops to around -5°C, making the frost prevention effect less pronounced. Smoke can easily cause widespread environmental pollution; fires close to fruit trees can easily ignite or scorch them, but are less effective at greater distances. Drones and high-altitude wind turbines are expensive and require specialized personnel to operate; installing high-voltage wind turbines in the field requires specialized high-voltage power transmission, which is not readily available in many orchards.

[0021] Specifically, the outer shell 1, the inner shell 2 and the combustion chamber shell 3 are all rectangular, the outer shell 1 and the combustion chamber shell 3 are both composed of upper, lower, front, rear, left and right shell walls, and the inner shell 2 is composed of upper, lower, left and right shell walls; the inner shell 2 is arranged inside the outer shell 1, and the combustion chamber shell 3 is arranged inside the inner shell 2, and the outer shell 1, the inner shell 2 and the combustion chamber shell 3 are located on the same axis; the front end of the inner shell 2 is connected and fixed to the front shell wall of the outer shell 1, and the rear end of the inner shell 2 is connected and fixed to the rear shell wall of the outer shell 1, and gaps are respectively left between the upper, lower, left and right shell walls of the inner shell 2 and the upper, lower, left and right shell walls of the outer shell 1 to form a thermal insulation interlayer 4; gaps are respectively left between the front and rear shell walls of the combustion chamber shell 3 and the front and rear shell walls of the outer shell 1 to form a thermal insulation interlayer 4; gaps are respectively left between the upper, lower, left and right shell walls of the combustion chamber shell 3 and the upper, lower, left and right shell walls of the inner shell 2 to form an air duct interlayer 5. Angle steel segments 12 are fixed around the front end of the combustion chamber shell 3. The right-angled sides of the four angle steel segments 12 are respectively connected and fixed to the four shell edges. The vertical plate edges of the four angle steel segments 12 are respectively connected and fixed to the upper, lower, left and right shell walls of the inner shell 2. The horizontal plate edges of the four angle steel segments 12 are all connected and fixed to the front shell wall of the outer shell 1. An annular cavity-shaped air distribution chamber 6 is formed between the four angle steel segments 12 and the upper, lower, left and right shell walls of the inner shell 2 and the front shell wall of the outer shell 1. Angle steel segments 12 are fixed around the rear end of the combustion chamber shell 3. The right-angled sides of the four angle steel segments 12 are respectively connected and fixed to the four shell edges, the vertical plate edges of the four angle steel segments 12 are respectively connected and fixed to the upper, lower, left and right shell walls of the inner shell 2, and the horizontal plate edges of the four angle steel segments 12 are all connected and fixed to the rear shell wall of the outer shell 1; an annular cavity-shaped air collecting chamber 7 is formed between the four angle steel segments 12 and the upper, lower, left and right shell walls of the inner shell 2 and the rear shell wall of the outer shell 1. A cold air inlet 13 is provided on the front wall of the housing 1, and is connected to the air distribution chamber 6. A hot air outlet 14 is provided on the rear wall of the housing 1, and is connected to the air collection chamber 7. Multiple heat-absorbing air ducts 8 are connected between the front and rear angle steel sections 12 of the combustion chamber housing 3. The multiple heat-absorbing air ducts 8 are evenly distributed around the upper, left, and right sides of the combustion chamber housing 3. The heat-absorbing air ducts 8 pass through the air duct interlayer 5, and their front end openings are connected to the air distribution chamber 6, and their rear end openings are connected to the air collection chamber 7.

[0022] In the device of this embodiment, the heat-absorbing air ducts 8 are distributed in parallel on the left, right and upper planes of the combustion chamber shell 3. Cold air enters the air distribution chamber 6 through the cold air inlet 13, and the combustion chamber shell 3 is heated into hot air. This side-heating air heating mode can avoid transporting hot air with flames to the orchard, causing combustion of trees or flammable materials.

[0023] In this embodiment, a closed, annular air duct interlayer 5 is located between the combustion chamber shell 3 and the inner shell 2. This interlayer duct 5 forms a wraparound heat storage tank structure, primarily serving to store heat, reduce ineffective heat dissipation, and enhance air mixing. This wraparound heat storage tank structure surrounds the combustion chamber shell 3, locking in as much heat as possible and minimizing ineffective heat loss. Cold air flows through the air distribution chamber 6 into the parallel heat-absorbing air duct 8, where heat exchange occurs to generate hot air. The hot air is then discharged through the air collection chamber 7 and hot air outlet 14.

[0024] To use the device of this embodiment, first place it near an orchard, with the hot air conveyor belt distributed between the rows. Connect the hot air outlet 14, high-pressure blower, and hot air conveyor belt. When the temperature of the hot air outlet 14 reaches 50°C-60°C, start the high-pressure blower, and transport the hot air through the hot air conveyor belt to the orchard.

[0025] Furthermore, the effect of the device of this embodiment was measured using a temperature and wind speed measuring instrument (the temperature on the test day was 4.6°C and the wind speed was 0 m / s; the warming effect = the temperature at the test point - the temperature measured on the day; the air disturbance effect = the wind speed at the test point - the wind speed on the day). The measurement results are shown in the following table:

[0026] Distance from the device (m) 10 50 100 150 Temperature (℃) 39.5 30.8 12.1 9.9 Warming effect (℃) 34.9 26.2 7.5 5.3 Wind speed (s / m) 22.8 19.9 2.3 1.2 Air flow disturbance effect (s / m) 22.8 19.9 2.3 1.2

[0027] It can be seen from the above table that at a distance of 10 meters from the device of this embodiment, the air warming effect in the orchard reaches 34.9°C, and the air disturbance effect is 22.8m / s; at a distance of 50 meters from the device of this embodiment, the air warming effect in the orchard reaches 26.2°C, and the air disturbance effect is 19.9m / s; at a distance of 100 meters from the device of this embodiment, the air warming effect in the orchard reaches 7.5°C, and the air disturbance effect is 2.3m / s; at a distance of 150 meters from the device of this embodiment, the air warming effect in the orchard reaches 5.3°C, and the air disturbance effect is 1.2m / s.

[0028] According to records, severe spring frost damage in orchards in northern my country typically occurs at temperatures around -4.8°C, with severe damage occurring in clear, cold, windless weather. This device (with a 1.5kW / 220V fan) can effectively raise the temperature in orchards within a 100-meter radius, maintaining it above 0°C and mitigating frost damage. The specific air disturbance effect can be modified by the fan power used.

[0029] The device of this embodiment adopts the technical combination mode of "air heating + air disturbance"; the surrounding heat storage box structure formed by the air duct interlayer 5 surrounds the combustion chamber shell 3, which increases the heat dissipation area, effectively reduces heat loss, and improves the thermal energy utilization efficiency; the heat absorption air duct 8 adopts a parallel connection method, which effectively increases the heat absorption area and improves the heating efficiency. The exhausted hot air adopts a side-heat output, avoiding the hidden danger of combustion caused by the flame brought by the direct heating hot air output.
