Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a strawberry planting greenhouse with a temperature regulating function. Background Art

[0002] Strawberry is a perennial herb. It is native to South America and is widely cultivated in China and Europe. Strawberries have high nutritional value, contain a variety of nutrients, and have health benefits. Strawberries prefer a warm and cool climate. The temperature for strawberry root growth is 5-30℃, the optimum temperature is 15-22℃, and the optimum temperature for stem and leaf growth is 20-30℃. At the same time, strawberry roots are shallow, transpiration is large, and water requirements are strict. In order to improve the yield and quality of strawberry planting, more and more farmers are planting strawberries in greenhouses at this stage.

[0003] At present, the existing strawberry planting greenhouse with temperature and humidity control function (such as patent number: CN215012033U) discloses a strawberry planting greenhouse with temperature and humidity control function, including a greenhouse body and a temperature and humidity regulating mechanism; the air inlet end of the hot air delivery main pipe is connected to the air outlet of the hot air source, and a plurality of branch air pipes are connected to the hot air delivery main pipe; the water inlet end of the spray main pipe is connected to the water source, a water pump is provided on the spray main pipe, and a plurality of spray branch pipes are provided on the spray main pipe; the branch air pipe and the spray branch pipe are both arranged vertically, and their ends are all blocked; a plurality of air outlets are opened on the branch air pipe, and a plurality of spray ports are provided on the spray branch pipe in a left-right alternating manner; the branch air pipe is arranged at the lower part of the inner cavity of the greenhouse body, and the spray branch pipe is arranged at the upper part of the inner cavity of the greenhouse body; the spacing between adjacent air outlets on the branch air pipe increases from bottom to top. The utility model is more uniform in regulating the temperature and humidity in the greenhouse, and the temperature and humidity control device has a simple structure and low cost.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The air distribution duct of the existing device is arranged vertically, which may affect the walking and movement of the staff when planting and picking strawberries, and also occupy the space for strawberry planting. Therefore, the existing device has the problem of affecting the staff's strawberry planting and occupying the strawberry planting space.

[0006] 2. The existing device is only provided with a structure for increasing the temperature in the greenhouse, but is not provided with a device for reducing the temperature inside the greenhouse body. When the internal temperature of the greenhouse body rises due to sun exposure, there is no cooling device, which may cause the strawberries to grow poorly or even wither and rot.

[0007] 3. The existing device is not equipped with a reasonable pressure reducing device. When the air distribution duct of the device continues to supply air to the inside of the greenhouse, the air pressure inside the greenhouse body will continue to increase. If the sealing performance of the greenhouse body is strong, the greenhouse body may be broken by the air pressure. If the sealing performance of the greenhouse is not strong, the greenhouse body will circulate with the external air, resulting in a faster temperature drop, which will cause the heating device to be used more frequently and cause a waste of resources.

[0008] 4. The air distribution duct of the existing device is vertically arranged and has an air supply port. The air supply port at the bottom is larger and is connected to a hot air delivery pipe at the bottom. When the air distribution duct delivers hot air to the greenhouse body, condensation will occur due to the large temperature difference, and condensation beads will be produced on the inner and outer walls of the air distribution duct. When there are too many condensation beads, they will flow to the bottom of the air distribution duct under the action of gravity, and may flow into the air distribution port opened at the bottom of the air distribution duct, and finally flow into the hot air delivery pipe, partially blocking the hot air delivery pipe, resulting in poor hot air delivery. The existing device is also provided with a spray pipe and a spray branch pipe to spray water to the inside of the greenhouse body. The water may be sprinkled onto the air distribution duct and finally enter the hot air delivery pipe through the air outlet, blocking the hot air delivery pipe. Therefore, the hot air delivery pipe of the existing device is easy to be blocked in actual use, resulting in the problem of poor hot air delivery caused by the blockage of the heating device body of the existing device.

[0021] (III) Beneficial effects

[0022] 1. The present application solves the problem that the existing device affects the strawberry planting of the staff and occupies the strawberry planting space by arranging the first auxiliary air duct and the second auxiliary air duct on both sides of the planting greenhouse body and not arranging a device protruding from the planting greenhouse body.

[0023] 2.

At the same time, start the two-way hot air blower to absorb the air inside the greenhouse body through the first main air duct and the first auxiliary air duct.

[0024] 3. When the temperature inside the planting greenhouse body is low and needs to be adjusted, start the two-way hot air blower to deliver hot air to the first main air duct.

When the two-way hot air blower delivers hot air to the inside of the planting greenhouse body, start the two-way fan. The two-way fan draws the air at the bottom of the planting greenhouse body through the second main air duct and the second auxiliary air duct, and at the same time draws the air at the top of the planting greenhouse body through the guide pipe, the third main air duct and the third auxiliary air duct, which will accelerate the flow of the hot air blown out by the first auxiliary air duct in the inside of the planting greenhouse body and also play a role in reducing pressure, preventing the first auxiliary air duct from continuously blowing air into the inside of the planting greenhouse body, increasing the air pressure inside the planting greenhouse body, thereby bursting the planting greenhouse body, solving the problem that the existing device may burst the planting greenhouse body and cause damage to the planting greenhouse body.

[0032] The embodiment of the present application provides a strawberry planting greenhouse with a temperature regulation function, which effectively solves the problems that the existing device affects the workers' strawberry planting and occupies the strawberry planting space, and is not equipped with a cooling device, which may cause damage to the greenhouse and easily lead to poor hot air delivery.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problems that the existing device affects the workers' strawberry planting and occupies the strawberry planting space, is not provided with a cooling device, may cause damage to the greenhouse and easily cause poor hot air delivery. The overall idea is as follows:

[0034] In view of the problems existing in the prior art, the utility model provides a strawberry planting greenhouse with temperature regulation function, including a planting greenhouse body 1 and a humidifying device 2, the humidifying device 2 is connected to the interior of the planting greenhouse body 1, and a two-way hot air blower 3 and a two-way fan 4 are arranged on the outside of the planting greenhouse body 1. The two-way hot air blower 3 is fixedly connected to a first main air duct 301 on the side close to the planting greenhouse body 1, and the two-way fan 4 is fixedly connected to a second main air duct 401 on the side close to the planting greenhouse body 1. The two-way fan 4 is installed on the side of the planting greenhouse body 1 away from the two-way hot air blower 3.

[0035] A plurality of first auxiliary air ducts 302 are fixedly connected to one side of the first main air duct 301 close to the planting greenhouse body 1 . The first auxiliary air ducts 302 penetrate the outer wall of the planting greenhouse body 1 and face the inside of the planting greenhouse body 1 .

[0036] The height of one end of the first auxiliary air duct 302 extending into the interior of the planting greenhouse body 1 is relatively low, and the height of the position where the first auxiliary air duct 302 is connected to the first main air duct 301 is relatively high.

[0037] A plurality of second auxiliary air ducts 402 are fixedly connected to one end of the second main air duct 401 close to the planting greenhouse body 1 . The second auxiliary air ducts 402 penetrate the outer wall of the planting greenhouse body 1 and face the inside of the planting greenhouse body 1 .

[0038] The height of one end of the second auxiliary air duct 402 extending into the interior of the planting greenhouse body 1 is relatively low, and the height of the position where the second auxiliary air duct 402 is connected to the second main air duct 401 is relatively high.

[0039] The two-way fan 4 is also fixedly connected to a guide duct 403, and one end of the guide duct 403 away from the two-way fan 4 is fixedly connected to a third main air duct 404, and the third main air duct 404 is fixedly connected to a plurality of third auxiliary air ducts 405. One end of the third auxiliary air duct 405 away from the third main air duct 404 passes through the top surface of the planting greenhouse body 1, and the first auxiliary air duct 302, the second auxiliary air duct 402 and the third auxiliary air duct 405 are all fixedly connected to the planting greenhouse body 1.

[0040] The first auxiliary air duct 302 , the second auxiliary air duct 402 and the third auxiliary air duct 405 are all fixedly connected to the planting greenhouse body 1 .

[0041] The opening size of the second auxiliary air duct 402 is one quarter of the opening size of the third auxiliary air duct 405 . The first auxiliary air duct 302 is close to the bottom surface of the planting greenhouse body 1 , and the position height of the first auxiliary air duct 302 is lower than the position height of the second auxiliary air duct 402 .

[0042] When the temperature inside the planting greenhouse body 1 is high, the two-way fan 4 is started to absorb external air and supply air in the reverse direction, and the external air is transported to the inner bottom surface of the planting greenhouse body 1 through the second main air duct 401 and the second auxiliary air duct 402, and then the air is supplied to the inner top of the planting greenhouse body 1 through the guide pipe 403, the third main air duct 404 and the third auxiliary air duct 405. At the same time, the two-way hot air blower 3 is started to absorb the air inside the planting greenhouse body 1 through the first main air duct 301 and the first auxiliary air duct 302. Because the cold air will sink, the air blown out by the third auxiliary air duct 405 can sink to the bottom of the planting greenhouse body 1, so as to realize the ventilation of the whole inside of the planting greenhouse body 1 to achieve the effect of cooling, thereby solving the problem that the existing device has no cooling device, which may cause the strawberry to grow poorly or even wither and rot.

[0043] Working principle:

[0044] The first step is, when the temperature in the planting greenhouse body 1 is low and needs to be adjusted, start the two-way hot air blower 3 to deliver hot air to the first main air duct 301, and the hot air enters the first auxiliary air duct 302 through the first main air duct 301 and is finally delivered to the inside of the planting greenhouse body 1. When the two-way hot air blower 3 delivers hot air to the inside of the planting greenhouse body 1, start the two-way fan 4. The two-way fan 4 draws away the air at the bottom of the planting greenhouse body 1 through the second main air duct 401 and the second auxiliary air duct 402, and at the same time draws away the air at the top of the planting greenhouse body 1 through the guide pipe 403, the third main air duct 404 and the third auxiliary air duct 405, which will accelerate the flow of the hot air blown out by the first auxiliary air duct 302 in the planting greenhouse body 1, and also play a role in reducing pressure, preventing the first auxiliary air duct 302 from continuously blowing air into the planting greenhouse body 1, which increases the air pressure inside the planting greenhouse body 1, thereby bursting the planting greenhouse body 1.

[0045] In the second step, when the temperature inside the planting greenhouse body 1 is high, start the two-way fan 4 to absorb external air and supply air in the reverse direction, and transport the external air to the inner bottom surface of the planting greenhouse body 1 through the second main air duct 401 and the second auxiliary air duct 402, and then supply air to the inner top of the planting greenhouse body 1 through the guide pipe 403, the third main air duct 404 and the third auxiliary air duct 405. At the same time, start the two-way hot air blower 3 to absorb the air inside the planting greenhouse body 1 through the first main air duct 301 and the first auxiliary air duct 302. Because the cold air will sink, the air blown out by the third auxiliary air duct 405 can sink to the bottom of the planting greenhouse body 1, so as to realize the overall ventilation of the interior of the planting greenhouse body 1 to achieve the cooling effect.

[0046] In the third step, because the first auxiliary air duct 302 and the second auxiliary air duct 402 are both arranged obliquely toward the planting greenhouse body 1 and are both installed on the outer wall of the planting greenhouse body 1, they will not be blocked by the water sprayed by the humidification device 2.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
