[0002] In the process of growing vegetables in greenhouses, ventilation is a key factor in regulating the temperature, humidity and air quality inside the greenhouse. Suitable ventilation conditions can provide a good environment for vegetable growth and promote healthy growth.

[0003] Traditional ventilation systems for vegetable greenhouses often have many shortcomings. For example, some systems have low ventilation efficiency, making it difficult to quickly and effectively regulate the temperature inside the greenhouse; and some systems have inflexible adjustments to ventilation volume and speed.

[0004] Meanwhile, during ventilation, dust and debris from the outside can easily enter the shed. Traditional devices have fixed filter structures, which cannot adjust the filtration effect according to actual needs. Furthermore, the installation and disassembly of some devices are cumbersome, making them inconvenient for later maintenance and replacement. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

Simultaneously, the system can control the fan's start / stop and operating power based on the greenhouse temperature.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: including a base frame assembly 1, a ventilation assembly 2 is provided at the rear top of the base frame assembly 1, and a filter assembly 3 is provided at the front top of the base frame assembly 1.

[0025] The base frame assembly 1 includes a soil pattern plate 101. A slanted slot 104 is provided on the rear part of the top surface of the soil pattern plate 101. A linear motor 105 is fixedly installed on the rear part of the top surface of the soil pattern plate 101. A fixing rod 106 is fixedly installed on the top surface of the slider of the linear motor 105.

[0026] The filter assembly 3 includes a vertical plate 301. A circular opening is provided on the front of the vertical plate 301, and an outer filter plate 302 is fixedly embedded in the circular opening. A rotating shaft 303 is rotatably installed at the center of the front of the outer filter plate 302. An inner filter plate 304 is fixedly sleeved at the rear end of the shaft of the rotating shaft 303. An arc-shaped toothed plate 305 is fixedly installed on one side of the back of the inner filter plate 304. A servo motor 306 is fixedly embedded on one side of the front of the vertical plate 301. A gear 307 is fixedly sleeved at one end of the output shaft of the servo motor 306.

[0027] In this embodiment, the ventilation component 2 includes a fan 201, a ventilation cover 202 is fixedly installed on the back of the fan 201, an inclined plate 203 is fixedly installed on the bottom surface of the fan 201, and fixed insertion holes 204 are provided on both sides of the bottom front of the fan 201.

[0028] Meanwhile, the inclined insert plate 203 is movably inserted into the inclined slot 104, and one end of the fixed insert rod 106 is movably inserted into the fixed insert hole 204.

[0029] The soil-shaped plate 101 has mounting sleeves 102 fixedly installed on both the front and rear of its bottom surface. A fixing bolt 103 is threaded into one side of the mounting sleeve 102. The entire device can be fixed in the preset position in the vegetable greenhouse by tightening the fixing bolt 103 to ensure the stability of the device during operation.

[0030] The vertical plate 301 is fixedly installed on the front of the top of the soil-shaped plate 101, and one end of the ventilation hood 202 is tightly attached to the back of the vertical plate 301.

[0031] The gear 307 meshes with the arc-shaped toothed plate 305, the front of the inner filter plate 304 is in contact with the back of the outer filter plate 302, and multiple filter ports are provided on the front of both the outer filter plate 302 and the inner filter plate 304.

[0032] When installing the ventilation assembly 2, align the inclined insert plate 203 on the bottom surface of the fan 201 with the inclined slot 104 on the rear of the top surface of the soil mold plate 101 and insert it. At this time, start the linear motor 105. The slider of the linear motor 105 drives the fixed insert rod 106 to move, so that the fixed insert rod 106 is inserted into the fixed insert holes 204 on both sides of the bottom front of the fan 201, thus completing the fixed installation of the ventilation assembly 2 and the base frame assembly 1.

[0033] When it is necessary to disassemble the ventilation assembly 2, the linear motor 105 is controlled to drive the fixed insertion rod 106 to move out of the fixed insertion hole 204, so that the ventilation assembly 2 can be removed from the base frame assembly 1.

[0034] The vertical plate 301 of the filter assembly 3 is fixed to the front top of the soil-shaped plate 101, and one end of the ventilation hood 202 is tightly attached to the back of the vertical plate 301 to ensure that air can pass smoothly through the filter assembly 3 during ventilation. The outer filter plate 302 is fixedly embedded in the round opening of the vertical plate 301, and the inner filter plate 304 is rotatably installed at the center of the front of the outer filter plate 302 via the rotating shaft 303, with the front of the inner filter plate 304 adhering to the back of the outer filter plate 302.

[0035] When it is necessary to adjust the filtration effect, vent opening / closing status, and ventilation efficiency, the servo motor 306 on the front side of the vertical plate 301 is activated. The output shaft of the servo motor 306 drives the gear 307 to rotate. The gear 307 meshes with the arc-shaped toothed plate 305 on the back side of the inner filter plate 304, thereby causing the inner filter plate 304 to rotate around the rotating shaft 303, changing the overlap area between the inner filter plate 304 and the filter openings on the outer filter plate 302. The larger the overlap area, the higher the degree of vent opening / closing, the stronger the ventilation efficiency, and the relatively weaker the filtration effect; the smaller the overlap area, the lower the degree of vent opening / closing, the weaker the ventilation efficiency, and the relatively stronger the filtration effect; when the filter openings are completely offset, the vents close, and ventilation stops.

[0036] During operation, the fan 201 starts, expelling air from inside the greenhouse through the ventilation hood 202 or drawing in outside air. By controlling the operating status of the fan 201, combined with the adjustment of the opening and closing degree of the vents and the ventilation efficiency by the filter assembly 3, precise temperature regulation inside the greenhouse is achieved. At the same time, the filter assembly 3 filters the air to ensure the cleanliness of the air entering the greenhouse.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
