[0002] Greenhouse agriculture refers to agriculture operated in artificial insulation facilities, which is a supplement to the field. There are two types: glass greenhouses and plastic greenhouses, which can artificially adjust the temperature and humidity. It is mainly used for the extra-seasonal cultivation of vegetables, so that they can be produced and supplied in winter and spring. In cold areas, greenhouse agricultural technology can also be used to obtain a variety of agricultural products. In Iceland, greenhouse agriculture is widely developed with geothermal heat as the heat source to obtain vegetables and fruits that cannot be cultivated under natural conditions. The cultivated area of greenhouse agriculture in my country is also developing rapidly, and its heat source is mainly coal. Greenhouses need to be ventilated frequently during use. On the one hand, carbon dioxide is needed for photosynthesis of plants. Ventilation can ensure the content of various air components in the greenhouse, including carbon dioxide, and on the other hand, it is also for more convenient regulation of the temperature in the greenhouse to avoid excessive temperature burning the seedlings and buds.

[0004] However, the above device has the problem that when adjusting the temperature inside the agricultural greenhouse, the temperature inside the agricultural greenhouse rises and falls slowly and the ventilation efficiency is low. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an agricultural greenhouse ventilation device, comprising a temperature regulating mechanism, a moving mechanism is arranged below the temperature regulating mechanism;
[0007] The temperature regulating mechanism includes a box body, a water pump is fixedly connected to the lower part of the box body, a nozzle is fixedly connected to the upper part of the water pump, a heater is fixedly connected to the upper part of the box body, a heating pipe is fixedly connected to the heater, an air outlet pipe is fixedly connected to the lower part of the heater, a mounting groove is opened in the middle of the front end of the box body, a fan is installed in the mounting groove, a guide pipe is fixedly connected to the front end of the box body, a ventilation pipe is fixedly connected to the upper part of the box body, an extension pipe is snap-connected to the upper part of the ventilation pipe, and a control device and a temperature sensor are fixedly installed on the upper part of the box body.

When the temperature inside the agricultural greenhouse is high, an external water pipe is connected to the water inlet pipe to start the water pump. After the water pump is started, water is pumped into a plurality of nozzles arranged above the water pump, and water mist is sprayed through the plurality of nozzles. The fan is started, and the fan generates suction to suck out the water mist, which is diffused into the agricultural greenhouse through a guide pipe, thereby lowering the temperature inside the agricultural greenhouse. When the temperature inside the agricultural greenhouse is low, the heating is started. After the heater is started, the heating tube inside the heater generates heat, and the heat is injected into the interior of the box through multiple air outlet pipes arranged below the heater. The hot air inside the box is extracted by the fan and transported to the interior of the agricultural greenhouse through the guide pipe, so that the temperature inside the agricultural greenhouse reaches a temperature suitable for farming. According to the position of the device, the extension tube is clamped on the top of the ventilation pipe to facilitate the extension of the extension tube out of the agricultural greenhouse to the outside. By starting the fan, the fan generates suction to suck the outside air into the ventilation pipe and blow it to the interior of the agricultural greenhouse through the guide pipe, thereby quickly adjusting the temperature inside the agricultural greenhouse and accelerating the ventilation efficiency.
[0009] Preferably, a plurality of the nozzles are provided, and the plurality of nozzles are distributed in a linear array above the water pump, and a water inlet pipe is fixedly connected to one side of the water pump.

[0014] Furthermore, by starting the heater, after the heater is started, multiple heating tubes inside the heater generate heat at the same time, the heat is ejected through multiple air outlet pipes arranged under the heater, and enters the guide tube with the assistance of the fan. The direction is controlled by the guide tube to allow the temperature to diffuse faster into the greenhouse. The protective net fixed on the inner wall of the front end of the guide tube can prevent the staff from putting their hands into the device and endangering the personal safety of the staff.

[0021] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0022] First, the utility model monitors the temperature inside the agricultural greenhouse in real time through a temperature sensor. The temperature sensor converts the sensed temperature into a usable output signal and transmits it to the control device. The control device controls the start of the water pump or heater. When the temperature inside the agricultural greenhouse is high, an external water pipe is connected to the water inlet pipe to start the water pump. After the water pump is started, water is pumped into multiple nozzles arranged above the water pump, and water mist is sprayed through the multiple nozzles. The fan is started, and the fan generates suction to suck out the water mist, which is diffused into the agricultural greenhouse through the guide pipe to reduce the temperature inside the agricultural greenhouse. When the temperature inside the agricultural greenhouse is low, the heater is started. The heater generates heat through the heating tube inside the heater after it is started. The heat is injected into the box through multiple air outlet pipes arranged below the heater. The hot air inside the box is extracted by the fan and transported to the agricultural greenhouse through the guide pipe, so that the temperature inside the agricultural greenhouse reaches a temperature suitable for farming. The extension pipe is clamped on the top of the ventilation pipe according to the position of the device, so that the extension pipe can be extended out of the agricultural greenhouse to the outside. By starting the fan, the fan generates suction to suck the outside air into the ventilation pipe and blow it to the inside of the agricultural greenhouse through the guide pipe, so as to quickly adjust the temperature inside the agricultural greenhouse and speed up the ventilation efficiency.
