Description

Technical Field

[0001] The utility model relates to the technical field of crop heating, in particular to a crop antifreeze heating device. Background Art

[0002] With the climate change we are currently experiencing, winter temperatures are generally milder and spring arrives earlier, so plants and flower buds emerge and develop relatively early in the year. However, during these relatively early periods, frost periods can still occur, particularly repeatedly threatening certain fruit crops, such as vineyards and orchards, over relatively large geographical areas.

[0003] In the utility model patent with the publication (announcement) number: CN214229168U, an outdoor crop heating device is disclosed, including a fuel tank, a fuel tank cover is provided on the fuel tank, a heat dissipation pipe, an oxygen opening regulator and a bypass pipe are provided on the fuel tank cover, the bypass pipe is an "L"-shaped pipe, one end of which extends into the heat dissipation pipe and communicates with the heat dissipation pipe, the other end of the bypass pipe extends into the fuel tank cover and communicates with the fuel tank, one end of the heat dissipation pipe vertically extends into the fuel tank cover and communicates with the fuel tank,

[0004] The other end of the heat dissipation pipe is connected to the chimney.

[0005] The oil and gas are sucked back into the fuel tank for secondary combustion, thus ensuring complete combustion of the fuel.

[0006] However, in the above device, the ratio of the diameter of the fuel tank and the heat dissipation pipe is not large enough, so secondary combustion is achieved by setting an "L"-shaped pipe in the heat dissipation pipe. The heating device made in this way has limited heating space for the heater, and the fuel maintenance time is relatively short. More heating devices need to be arranged outdoors, which is costly. Utility Model Content

[0007] The utility model aims to provide a crop antifreeze heating device, which increases the capacity of the heater, prolongs the interval of adding fuel, has better heat dissipation effect, low fuel cost, and can preserve heat for a long time.

[0008] In order to achieve the above-mentioned purpose, the utility model provides a crop antifreeze heating device, including a furnace body, which is a circular furnace body. A heat dissipation pipe is arranged on the furnace body, and an inverted triangular heat dissipation hole is arranged on the heat dissipation pipe. An extension pipe is also connected to the upper end of the heat dissipation pipe. The ratio of the diameter of the furnace body to the diameter of the heat dissipation pipe is: 6.5:1~4.8:1.

[0009] A further improvement is that the inverted triangular heat dissipation holes are evenly arranged on the heat dissipation pipe along the circumference of the circular heat dissipation pipe, and the inverted triangular heat dissipation holes are 8 to 10 groups.

[0010] A further improvement is that a top cover is also provided on the extension tube to ensure the safety and fixation of the flame and prevent it from burning surrounding objects.

[0011] A further improvement is that furnace teeth are also provided in the furnace body, so that the combustion is more complete and more heat is released in the same time.

[0012] A further improvement is that a furnace door is also provided on the furnace body.

[0013] A further improvement is that handles are provided on both sides of the furnace body to facilitate outdoor transportation, installation and placement.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the capacity of the heater is increased by increasing the diameter ratio of the furnace body and the heat dissipation pipe (6.5:1-4.8:1); at the same time, in order to ensure better combustion and heat dissipation effects, inverted triangular heat dissipation holes are provided on the heat dissipation pipe, which play a role of backflow, allowing heat to flow from bottom to top along the ground, which can quickly increase the temperature of the local small environment and the heating range, and reduce heat loss.

[0018] like Figure 1 to Figure 2 As shown, a crop antifreeze heating device includes a furnace body 5, which is a circular furnace body. A heat dissipation pipe 2 is arranged on the furnace body 5, and an inverted triangle heat dissipation 8 is arranged on the heat dissipation pipe 2. An extension pipe 3 is also connected to the upper end of the heat dissipation pipe 2, and a top cover 4 is also arranged on the extension pipe 3 to ensure the safety and fixation of the flame and will not burn surrounding objects.

[0019] The ratio of the diameter of the furnace body 5 to the diameter of the heat dissipation tube 2 is 6.5:1 to 4.8:1, which increases the capacity of the heater.

[0020] The inverted triangle heat dissipation holes 8 are evenly arranged on the heat dissipation tube 2 along the circumference of the circular heat dissipation tube, and the inverted triangle heat dissipation holes 8 are 8 to 10 groups.

[0021] Among them, furnace teeth 6 are also arranged in the furnace body 5. The addition of furnace teeth design can make the combustion more complete and release more heat in the same time.

[0022] The furnace body 5 is also provided with a furnace door 1, and handles 7 are also provided on both sides of the furnace body 5 to facilitate outdoor transportation, installation, and placement.

[0023] The utility model crop antifreeze heating device increases the capacity of the heater by increasing the ratio of the diameter of the furnace body and the heat dissipation pipe (6.5:1 to 4.8:1), and prolongs the interval of adding fuel from 30 minutes to 120 minutes compared with the prior art. At the same time, in order to ensure better combustion and heat dissipation effects, the heat dissipation pipe is provided with inverted triangle heat dissipation holes (the inverted triangle heat dissipation holes are evenly arranged on the heat dissipation pipe along the circumference of the circular heat dissipation pipe, and the inverted triangle heat dissipation holes are 8 to 10 groups), which plays a role of backflow, allowing heat to flow from bottom to top along the ground, which can quickly increase the temperature of the local microenvironment and the heating range, and reduce heat loss.

[0024] When in use, when the temperature drops over a large area outdoors, an antifreeze heating device for crops can be set up at certain intervals. Natural materials such as firewood and straw can be burned locally. After the firewood is burned, the heat can be retained for a long time, extending the interval for adding fuel from 30 minutes to 120 minutes compared to the existing technology. The inverted triangle heat dissipation holes allow heat to flow from bottom to top along the ground, which can quickly increase the temperature of the local microenvironment and the heating range, effectively reducing the losses caused by natural disasters to agricultural production. It has a simple structure and is easy to operate.
