Description

Agricultural Ventilator {agriculture ventilation}

The present invention mainly relates to an agricultural ventilator that can ventilate the interior, such as plastic houses, greenhouse pigs, cages, mushrooms, nursery. The feature of the present invention is not only to have a simple opening and closing structure and usability, but also to have a strong feature on the external environment, such as rain, snow, wind, so that it can be widely used as an agricultural ventilator. Generally, pigs, barns, and plastic houses are equipped with various ventilation devices for indoor ventilation. The ventilation window is used to distribute indoor air to the outside to maintain the proper temperature or to provide fresh air, so that the agricultural and livestock can be grown and grown under optimum growth conditions.

Therefore, the present invention provides a more stable and convenient usability and operability by allowing the ventilation fan to be automatically opened by the operation of the ventilation fan when the ventilation fan is in operation, and automatically opening the ventilation window. The ventilation window is installed at the bottom of the ventilator so that it is not opened by the external wind, so the cold air can not enter the inside, and it is especially strong against the weather because it prevents leakage by the unobstructed roof.

1 is a perspective view showing the configuration of the present invention, Figure 2 is a cross-sectional view showing an operating state of the present invention. The fan body 4 is formed in a substantially circular tubular shape, and the non-obstructed roof 1 fixed by the connecting pin 2 is prevented from entering snow or rain through the ventilation hole 3 at the upper end of the fan body 4. It is formed on the hole (3). The unobstructed roof is formed somewhat higher than the ventilation hole 3 to facilitate the flow of air through the ventilation hole 3. In addition, a fixing part 41 is formed on the middle circumference of the fan body 1 to fix the fan body to a frame of a vinyl house. The fixing portion 41 is bored to be wound around the frame with a string or the like in order to fix the installation in the frame or the like of the plastic house in almost all directions. The blower fan 5 is installed in the lower middle part of the fan body 4 to blow and vent indoor air, such as a vinyl house in which the fan is installed, to the outside. The blower fan 5 is installed by fixing and seating the motor 51 using the motor fixing pin 6 in the middle lower portion of the fan body 4. Naturally, the blower fan 5 is the same as a conventional blower means in which a fan is coupled to the rotation shaft of the motor 51. The blower fan 6 may use various known equivalent means. In addition, a power line for supplying power and a switch (not shown) are naturally connected to the blowing fan 6. The opening and closing plate 7 installed on the bottom of the ventilator body 4 is formed in an incomplete circular shape, one end of which is cut off around the fixed shaft 8, and is fixed to the fixed shaft 8 coupled to the ventilator body 4. Combined to rotate. The end of the opening and closing plate 7 is cut off from the opening and closing plate 7 at the bottom of the ventilator body 4 to prevent any opening due to the difference in weight from the complete semicircle portion around the fixed shaft 8. A slightly larger sized open membrane 42 is attached, shaped like a part. Accordingly, the opening and closing plate 7 rotates around the fixed shaft 8 about the central axis, and opens and closes. The opening and closing plate 7 normally closes the lower end of the fan body 4 by the opening membrane 42. If it is lifted up by blowing or other force, it is returned to its original position by asymmetrical weight difference. The present invention configured as described above can be effectively used for the purpose of installing them in a plastic house, money, barn, etc. Looking at the operation of the present invention below. When the switch is operated to operate the opening and closing plate 7, the blowing fan 5 rotates to perform the blowing operation. Therefore, the blowing force of the blowing fan 5 by the blowing operation is to force the opening and closing plate (7), which is closed on the lower part of the fan main body (4) around the fixed shaft (8) to open and close the opening plate (7) ) Is lifted up and the air is blown outward. Since the opening and closing plate 7 is rotatably coupled to the fixed shaft 8, the semi-circular portion of the opening and closing plate 7 is lifted up and opened, as shown in FIG. 2, around the fixed shaft 8. Then, when the switch is turned off while performing the ventilation operation as described above, the blowing force to lift the opening and closing plate 7 disappears, so that the opening and closing plate 7 is completely centered on the fixed shaft 8 by the difference in weight. The semicircle section is lowered and closed. Therefore, the ventilation window is automatically opened and closed only by driving the blower fan 5. The cover 4 of the outer periphery of the ventilation opening 2 prevents the draft from being lifted arbitrarily by the draft, for example, in a state where the draft plates 3 and 3 'are closed to provide stable operability and usability. Will be.

As described above, the present invention is a ventilation window is arbitrarily opened and closed only by the blowing operation of the blower fan, the opening and closing plate is installed on the bottom of the fan body, there is no phenomenon of opening by outside wind, the outside cold air can not enter the inside, With the screening of the roof to prevent leakage, it is practical, convenient, and can provide stable operability and operability. It is simple in structure and easy to manufacture, so it can be produced at low price. As a result, it can be spread to various fields such as vinyl houses, barns, and poultry farms, thereby achieving various advantages such as increasing their productivity and improving operational stability.
