The present invention relates to a ventilation window opening and closing device of the greenhouse for opening and closing the ventilation window of the greenhouse is installed to control the temperature and humidity of the greenhouse, in particular the ventilation window opening and closing device of the greenhouse for opening and closing the ventilation window installed on the roof of the greenhouse using the winding and the rope It is about.

Typically, a ventilation window is installed in the greenhouse in order to properly maintain the culture temperature of the flowers or vegetables growing in the greenhouse. The location of the ventilation window can be installed on the side of the greenhouse in the form of a window, but it is generally installed on the roof so that the plants in the greenhouse do not directly hit the cold wind.

At this time, as a method for opening and closing the ventilation window, a method using a rotating shaft for opening and closing the ventilation window and an operation interlocking with the rotating shaft is widely used. Therefore, Japanese Unexamined Utility Model Publication No. S61-25760 similar to the technique of the present invention (block name: Japanese name: ビ ニ イ ル ハ ス の シ ー ト 비닐) for vinyl house is introduced below.

In the conventional barrier film opening and closing device for a vinyl house, as shown in FIG. 7 and FIG. 8, a rotation shaft 51 is installed at an upper end portion of the central support 61, and the barrier film 50 is formed between the double-formed frames 62. The combined operating rod 52 is provided, and a winding drum 53 is formed on the rotary shaft 51, and pulleys 54 are installed at both ends of the frame 62, respectively. The winding drum 53 is adapted to be connected to the rope 63 via the pulley 54. In addition, a chain sprocket 55 is formed in the rotary shaft 51, so that the rotational force of the motor (not shown) is transmitted to the rotary shaft 51 through the chain 60 so that the rotary shaft 51 is rotated.

In the conventional barrier film opening and closing device for a vinyl house configured as described above, the operation membrane 52 is moved in accordance with the rotation of the rotary shaft 51 such that the barrier membrane 50 opens or closes the ventilation window or the light transmission window.

When the motor (not shown) is rotated, the chain sprocket 55 connected to the chain 60 is rotated to rotate the rotation shaft 51. When the rotary shaft 51 is rotated, the winding drum 53 is also rotated so as to wind or unwind the rope 63 to move the operation 52 up and down.

That is, when the rotating shaft 51 is rotated in the direction of the arrow shown in FIG. 8, the upper rope 63a is wound around the winding drum 53 and pulls up the operation section 52 through the upper pulley 54a. . At the same time, the lower rope 63b is released from the winding drum 53 to allow the operation 52 to move freely through the lower pulley 54b. Therefore, since the operation membrane 52 is raised to expand the barrier membrane 50, the ventilation window or the light transmission window at the top of the vinyl house is blocked by the barrier membrane 50.

At this time, the pulley 54 reduces the loss of power by allowing the rope 63 to move without great friction. In addition, when the rotary shaft 51 is rotated in the opposite direction of the arrow, the winding drum 53 is also rotated in the reverse direction to lower the operating period 52, the blocking film 50 in accordance with the lower operation period 52 ) Will open the ventilation or transmission window.

However, the conventional barrier membrane opening and closing device for the vinyl house configured as described above requires a separate connection member in connecting the operation between the operation 52 and the rotary shaft 51, the configuration is complicated, the assembly is inconvenient, the price and The load is increased, and power is transmitted through a plurality of members to open and close the blocking film 50 even when the blocking film 50 is opened or closed, thereby increasing power loss.

The present invention has been made to solve the above-mentioned problems of the prior art, simplifying the structure of the opening and closing device of the ventilation window to reduce the number of related parts to reduce the total load and to facilitate the assembly and the unit cost and installation cost of the product The purpose is to provide a ventilation window opening and closing device of the greenhouse that can be reduced.

Another object of the present invention is to connect the rope to the winder without connecting the rotary shaft installed between the ventilation window and the power transmission means when opening and closing the window and to connect the end portion to the ventilation window so that the ventilation window slides along the slope of the roof. The purpose is to provide a ventilation window opening and closing device of the greenhouse that can minimize the power loss.

The present invention for achieving the above object is installed on the greenhouse roof inclined at right angles to the transverse skeleton installed in the longitudinal direction of the greenhouse and the lower glass window support formed with a groove portion for fixing the one side of the glass window covering the lower part of the greenhouse roof, A rail support formed on both ends of a ventilation window fixing frame coupled with a rail formed on the upper side of the recess, a ventilation window covering the upper part of the greenhouse roof, and a roller mounted on the roller support and positioned on the rail formed on the glass window fixing support. And a stopper formed in the longitudinal direction of the greenhouse at the upper end of the lower glass window support to limit the vertical movement of the ventilation window fixing frame, and guided to the guide roller formed at the upper portion of the greenhouse roof and bound to the lower roller support. Composed of ropes wound by the machine It is characterized by.

Hereinafter, an embodiment of the ventilation window opening and closing apparatus of the greenhouse according to the present invention will be described with reference to the accompanying drawings.

According to the present invention, the lower windshield support 21 supporting the window 20 installed in the lower part of the greenhouse roof and the ventilation window fixing fixing the ventilation window 10 for opening and closing the roof of the greenhouse as needed while covering the upper part of the greenhouse roof It is composed of a frame 11, a rope 4 for sliding the ventilation window 10, and a winder 5 for winding the rope 4.

The lower glass window support 21 is mounted so that the bottom of the support 21 is in contact with the transverse frame 3 installed on the roof of the greenhouse, and the clamp 6 surrounding the bottom and one side of the transverse frame 3. The projecting surface 6 'and the bottom end of the lower window support 21 are covered with a clip 7 and then the bolt 8 is screwed in so that the lower window support 21 is fastened to the transverse skeleton 3.

One surface of the glass 22 covering the lower portion of the greenhouse roof is inserted into the recess 24 formed on the side of the lower window support 21, and the glass 22 is lowered by the packing 18. Is closely supported.

On the upper side of the lower glass window support 21 is formed a rail 23 that can be rotated while the roller 14 is supported.

Similar to the lower window support 21, the ventilation window fixing frame 11 is also inserted into the groove 12 formed on the side surface of the glass 12 is inserted into the packing (not shown), the glass 12 is a ventilation window fixing frame 11 Tightly fixed to the

The roller support 13 is fastened by the fastening screw 19 at both ends of the ventilation window fixing frame 11, and the roller 14 is provided in the roller support 13. As shown in FIG. The roller 14 is rotatably supported on the rail 23 of the lower window support 21, and the recess 15 is formed at one end of the roller support 13, and the packing 15 is fitted therein. The packing 15 serves to eliminate the gap between the ventilation window 10 and the lower glass window 20 and to alleviate the impact of opening and closing the ventilation window 10.

The lower glass window support 21 has a roller support on the upper end portion of which the glass 22 is inserted, when the stopper 9 having a square frame shape is assembled in the longitudinal direction of the greenhouse so that the ventilation window 10 is completely opened or closed. The packing 15 inserted into 13 is in contact with one side of the stopper 9.

The lower roller support of the roller supports 13 assembled at both ends of the ventilation window fixing frame 11 is coupled with a rope 4 to be guided by a guide roller 2 mounted at the upper part of the frame of the greenhouse roof. 5) is connected.

Referring to the effects of the present invention configured as described above are as follows.

If the ventilation window 10 is to be opened while the ventilation window 10 of the greenhouse is completely closed, as shown in FIG. 2 or FIG. 3, when the winder 5 is operated so that the rope 4 is released, the ventilation window 10 is self-weighted. By the roller 14 is rotated by the rail 23 of the lower window support 21 to move to the lower side. When the ventilation window 10 comes down to the position to be opened, the operation of the winder 5 is stopped and the ventilation window 10 stops at a desired position.

As the rope 4 is released, the ventilation window 10 continues to move so that the packing 15 inserted into one side of the roller support 13 is assembled in the middle of the lower window support 21 as shown in FIG. One surface of the stopper 9 is brought into contact with the ventilation window 10 so as to be completely supported and opened.

When the ventilation window 10 is to be closed, the winding machine 5 is operated to wind the rope 4 so that the ventilation window fixing frame 11 is raised so that the ventilation window 10 is closed. Since the specific operation is the same as the case of opening the ventilation window 10, a detailed description thereof will be omitted.

However, when the ventilation window 10 is closed, more power is required than when the ventilation window is opened. That is, when opening the ventilation window 10, simply loosen the rope 4, so the power is hardly consumed. However, when the ventilation window 10 is closed, the ventilation window fixing frame 11 should be pulled up by winding the rope 4. More power is required than when opening the ventilation window 10.

As described above, the present invention has an effect that the configuration of the present invention is extremely simple and the mutual assembly state is tight and the opening and closing degree of the ventilation window can be easily adjusted with minimal power.

In other words, the winder and the ventilation window fixing frame are connected to the rope, and the winding machine opens and closes the ventilation window only by winding or unwinding the rope, so the configuration is extremely simple. When opening the ventilation window, the self-weight of the ventilation window fixing frame is used. Not only is the loss very low, it is also possible to freely adjust the opening and closing degree of the ventilation window just by adjusting the amount of loosening of the rope.
