Description

Technical Field

[0001] The invention relates to the technical field of tree antifreeze, and in particular to a device for protecting fruit trees from frost damage. Background Art

[0002] The impact of frost damage on fruit tree yield is one of the most concerned issues for fruit farmers. In Xinjiang (February to May), when the temperature drops below the limit that the flower buds of fruit trees can withstand, the flower buds may be frostbitten or necrotic. Frozen flower buds will directly reduce the number of flowers. For example, when the flower buds of walnut trees are frozen, the scales will gradually dry up and turn black. In severe cases, the cell structure inside the flower buds is destroyed, completely losing its activity, and appearing dry and dead, which seriously affects the fruit yield of the year.

[0003] At present, the main methods of preventing fruit trees from freezing damage are physical protection and chemical protection. The trunks are whitewashed, and the white coating is used to reflect sunlight, reducing the trunk's absorption of solar radiation, thereby reducing the temperature difference between day and night and preventing drastic temperature changes from causing freezing damage to the trunks. Covering the roots with soil effectively blocks cold air and has a thermal insulation effect by covering the roots with a certain thickness of soil. Covering the ground with cloth or straw, spread on the ground around the roots of trees, can not only reduce soil heat loss and stabilize soil temperature, but also inhibit water evaporation, creating a good growth environment for tree roots. However, these measures have limited protection range and mainly act on the trunk part. They have limited antifreeze effect on flower buds, branches and other parts. They are mainly used in winter and cannot protect fruit tree flower buds during the cold period of late spring.

[0004] Chemical antifreeze mainly uses chemical substances to lower the freezing point of fruit tree flower buds, or to enhance the cold resistance of flower buds. Some chemical agents can increase the concentration of cell sap. According to the colligative principle of solution, the increase of solute concentration will lower the freezing point of the solution. Some chemical agents can also regulate the physiological processes of plants, such as enhancing the stability of cell membranes, so that flower buds can maintain normal cell functions in low temperature environments and reduce the occurrence of frost damage. However, in the case of changeable weather, such as repeated rise and fall of temperature, the protective effect of chemical agents will also be affected. Every time the temperature rises, the physiological activity of the flower buds will increase, and part of the agent may be consumed or decomposed. When the temperature drops again, the remaining amount of the agent may not be enough to provide adequate protection. Summary of the invention

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] Embodiment 1

[0035] like Figures 1 to 5 As shown, the present invention provides a device for protecting fruit trees from frost damage, comprising:

[0036] The combustion mechanism releases heat and produces smoke by burning fuel;

[0037] The heat pipe 1 is installed at the smoke outlet of the combustion mechanism, and a smoke outlet 2 is installed at the end of the heat pipe 1. The heat pipe 1 is used to transport the heat released by the combustion of the fuel and the smoke generated to the plant and row spaces between the fruit trees in the orchard;

[0038] The lifting and adjusting component is used to detect the temperature in the orchard and adjust the position of the smoke outlet 2.

[0039] The present invention releases a large amount of heat energy through the combustion process carried out in the combustion mechanism. This heat energy is directly dissipated into the surrounding air through the heat pipe 1, so that the air temperature near the ground in the orchard increases. Since the density of the hot air generated by the combustion is relatively small, the smoke will rise and form a relatively warm air layer above the orchard to cover the orchard, which can not only slow down the speed of heat loss to the high altitude, but also block the direct invasion of cold air, further play a role in heat preservation, thereby maintaining a higher temperature in the orchard. At the same time, the smoke generated by the combustion is accurately transported to the plant and row space between the fruit trees. The tiny particles in the smoke have the function of absorbing and reflecting the heat radiated from the ground. After the ground absorbs solar radiation and heats up, it will release heat to the atmosphere in the form of long-wave radiation. At this time, the particles in the smoke can reflect part of the heat back to the ground, reducing the heat loss from the ground.

[0040] The present invention can significantly reduce the frost damage caused by low temperature weather to branches, flowers and buds of fruit trees, create a more favorable environment for the growth of fruit trees, effectively increase the fruit setting rate of fruit trees, and ensure the yield and income of the orchard.

[0041] Further optimizing the scheme, in order to facilitate the movement of the device, the present invention also includes:

[0042] The cart 3, the combustion mechanism and the lifting and adjusting components are all installed on the cart 3.

[0043] The pallet 3 is mainly made of 3 mm thick stainless steel sheet.

[0044] According to a further optimized solution, the combustion mechanism includes a furnace 4, which is provided with a furnace door 5 and a furnace 6; an opening for installing a heat pipe 1 is provided on the top of the furnace 4; and a vent 10 is provided on one side of the furnace 4.

[0045] According to a further optimized solution, the combustion mechanism further includes a blower 7 , which is connected to the stove 4 via a vent 10 .

[0046] The furnace 4 is made of 2mm thick stainless steel plate, with a bottom of a square with a side length of 0.8cm and a top of a square with a side length of 0.4cm, and an opening with a diameter of 0.3cm for connecting the heat pipe 1; the furnace 4 is equipped with a furnace door 5 with a length of 0.4m and a height of 0.5m and a furnace chamber 6 with a length of 0.6cm and a width of 0.3m; a vent 10 with a diameter of 0.2m is opened on the side of the furnace 4, and the vent 10 can be used for ventilation and an external blower 7 to increase the heat output rate.

[0047] According to a further optimized solution, the heat-conducting pipe 1 is an aluminum hose.

[0048] The heat pipe 1 is made of 0.1 mm thick soft aluminum and has a diameter of 0.28 cm.

[0049] A further optimized solution is that in order to stably place the heat pipe 1 in the furnace 4 , a buckle 8 is provided at one end of the heat pipe 1 close to the furnace 4 , and the heat pipe 1 is installed on the opening of the furnace 4 through the buckle 8 .

[0050] According to a further optimized solution, the smoke outlet 2 is a flat-mouth structure.

[0051] The smoke outlet 2 is made of 2mm thick heat-resistant ABS plastic and is 0.5m long. When smoke is blown out through the smoke outlet 2, the airflow direction will be more regular, the flow rate will be faster and the coverage area will be larger. The smoke outlet 2 is connected to the heat pipe 1 through a threaded structure.

[0052] According to a further optimized solution, the lifting and adjusting assembly includes a base 9, on which an infrared sensor 17, a screw-driven lifting rod 11, a motor 12 and a controller 13 are mounted;

[0053] The infrared sensor 17 is used to detect the temperature in the orchard;

[0054] A support buckle 14 is installed at the end of the screw drive lifting rod 11, and the screw drive lifting rod 11 is connected to the heat pipe 1 through the support buckle 14;

[0055] The motor 12 is used to drive the screw drive lifting rod 11 to extend and retract;

[0056] The infrared sensor 17, the screw drive lifting rod 11 and the motor 12 are all electrically connected to the controller 13, and the controller 13 is used for signal reception and information processing.

[0057] According to a further optimized solution, the support buckle 14 is an annular structure, and the support buckle 14 includes a fixed buckle installed on the screw drive lifting rod 11, and a movable buckle is rotatably connected to the fixed buckle.

[0058] According to a further optimization scheme, a handle 15 is installed at one end of the cart 3, and a plurality of through holes 16 for installing the combustion mechanism and the lifting and adjusting components are opened on the body of the cart 3.

[0059] The device for resisting frost damage to fruit trees provided by the present invention has a working principle as follows: smoke generated by burning coal slag, straw, etc. in a stove 4 is discharged through an aluminum hose installed at the stove mouth, and the aluminum hose is fixed by a support buckle 14 on a screw-driven lifting rod 11. The smoke discharge position can be controlled by adjusting the height of the screw-driven lifting rod 11, thereby achieving the purpose of adjusting the smoke blowing angle and height, helping the branches, flowers, and buds of fruit trees to resist frost damage accurately, ensuring that fruit trees can be protected more accurately, effectively, and safely in a low temperature environment, and minimizing the adverse effects of frost damage on the growth and yield of fruit trees.

[0060] Embodiment 2

[0061] The difference between this embodiment and the first embodiment is that, in order to increase the smoke concentration and improve the effect of fruit trees resisting frost damage, an annular nozzle is arranged at the position of the vent 10, and the annular nozzle is connected to a water source through a pipeline to control the water flow to spray out to form water mist. The spraying speed is controlled at 10-50ml / min per minute, the continuous spraying time is within 10 minutes, and the total spraying amount is 50-100mL.

[0062] The contact between water mist and the fuel surface affects the completeness of combustion to a certain extent, increases the smoke concentration, and also has a certain humidification effect on the smoke.

[0063] Through the setting of the annular nozzle, the furnace 4 can continuously emit smoke for 30 minutes, and the smoke output can reach 700-1000 cubic meters (NM 3 ), the smoke produced can cover at least 1 acre of orchard.

[0064] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
