Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to, for example, an agricultural tunnel that can be opened and closed by air.

When opening tunnels such as conventional agricultural vinyl tunnels,
A person has to manually tear apart the two overlapping sheets from the left and right sides of the tunnel ceiling, or pull up the sheets at the bottom of the tunnel, which is extremely difficult when there are multiple tunnels over a large area. It was time consuming and hard work.

The same thing happened when closing the tunnel. The present invention is a tunnel for agricultural use that solves the above-mentioned problems, and can be opened and closed by air.

The present invention will be explained in detail below with reference to illustrative drawings.

In manufacturing the tunnel of the present invention, first, as shown in Figures 1, 2, or 4, a semicircular tunnel outer aggregate 1 made of steel wire, plastic wire, glass fiber wire, etc. A plurality of inner aggregates 2 are maintained at appropriate intervals by a spacer 3 to form a set of tunnel aggregates, and a plurality of sets are successively pierced into the ground 12 in parallel to form aggregates.

■Next, as shown in Figures 1 and 3, a large number of bags 6 are formed in a plastic sheet made of vinyl chloride, polyethylene, etc. at appropriate intervals in the height direction, and when tunnels are conveyed through these bags 6, the tunnels are formed in the length direction. A sheet 4 having a bag 5 and a burying space 7 such that the lower end of the sheet in the height direction can be buried underground.
Make two pieces.

■ These two tunnel sheets 4 are arranged so as to pass between the outer aggregate 1 and the inner aggregate 2 from the left and right ends of the tunnel aggregate, respectively, as shown in Figures 1, 2, 3, or 4. Then, the filling space 7 of each sheet is buried in the ground 12 on the left and right sides of the tunnel.

In this way, a tunnel is formed by covering the framework with a sheet.
■ As shown in Fig. 1, a ventilation pipe 9 made of rubber or vinyl chloride is attached to the end of the bag 5 in the length direction of the tunnel sheet 4 so as to convey it, and the end of the ventilation pipe 9 is, for example, An air blowing fan 10 such as an electric Sirotskov fan and an exhaust valve 11 such as a solenoid valve or a manual valve are provided. This completes the installation of the tunnel. The method of operating this tunnel is as follows.

■ By closing the exhaust valve 11 and rotating the ventilation fan 10, the lengthwise bags 5 and the heightwise bags 6 on both left and right sides of the tunnel sheet 4 are filled with air. The tunnel expands in the tunnel height direction along the space between the outer aggregate 1 and the inner aggregate 2 and closes as shown in FIG. 2 or 3. ■ Also, by stopping the ventilation fan 10 and opening the exhaust valve 11, the air that has been filled in the bags 6 in the height direction and the bags 5 in the length direction of the tunnel sheet 4 is passed through the ventilation pipe 9 for exhaust. When the tunnel sheet 4 is discharged from the valve 11, the outer aggregate 1 and the inner aggregate 2 are separated by its own weight.
The tunnel opens as shown in Figure 4.

In addition, when the tunnel is closed during the installation of the tunnel, a part of the ceiling of the outer frame 1 is covered with vinyl chloride as shown in Figures 1, 2, or 3 to prevent rain from flowing into the tunnel. Alternatively, a ceiling sheet 8 made of a polyethylene sheet or the like may be pasted.

In addition, when actually operating the tunnel, the rain gauge and the blower fan are linked, and when it starts to rain, the blower fan is rotated, and the exhaust valve is closed using the solenoid valve, filling the bag with air and closing the tunnel. If you do this, it will be convenient.

Alternatively, you can link the thermometer and the blower fan, and when the temperature falls below the set temperature, turn the blower fan and close the tunnel to keep warm. When the temperature rises above the set temperature, stop the blower fan, open the air exhaust valve, and release the air inside the bag. If you let the air out and open the tunnel, you can use it as a stool.

Furthermore, the air blowing pipes are passed through the tunnel sheet bags of the tunnels at multiple locations, and the tunnels at multiple locations are opened and closed simultaneously using an exhaust valve Z consisting of one or more ventilation fans and one or more electromagnetic valves. There is also.

Furthermore, when keeping the tunnel closed, if the blower fan 10 is constantly running, the amount of electricity used will increase.
0 may be operated in a pulse manner. Experimental examples of the tunnel of the present invention are shown below.

■ Outer aggregate 1 and inner aggregate 2 made of steel wire with diameter 4 sides ◇
The diameter of both aggregates 1 and 2 is 4 to maintain the distance of 4 skins.
Welded to the baser 3 made of steel wire at the ribs to form a set of aggregates forming an H shape, o. Forty-one pairs of aggregates were pierced into the ground side for each shoe to form a tunnel framework with a length of 20 h, a width of 1 m, and a height of 0.6 h.

(See Figures 1 and 2) At this time, the length of the outer aggregate is longer than the length of the inner bone village. ■ A bag 5 in the length direction made of a vinyl chloride sheet with a side thickness of 0.05 cm and a bag 5 in the length direction with an inner diameter of 5 and a length of 2. Two tunnel sheets each having a length of 2 mm and a width of 1 m were prepared by pasting 79 bags 6 in the height direction onto a vinyl chloride sheet with a side thickness of 0.05 mm using a heat sealing method.

(See Figures 1, 2 and 3). ■ Pass the above two sheets from the left and right sides of the spacer 3 between the outer aggregate 1 and the inner aggregate 2, and pass them through the bottom 2 of the bag 5 in the length direction & the desk padding 7.
is buried in the ground, and a ventilation pipe 9 made of a vinyl chloride pipe with an outer diameter of 5 arcs and a wall thickness of 0.3 arcs is connected to one end of the bag 5 in the length direction of each of the left and right tunnel sheets 4 and air. The other end of this ventilation pipe 9 is connected to the air outlet of an electric sirocco fan 10 with a capacity of 0.04 〆/min. It was attached to a manual exhaust valve 11 made of hard vinyl chloride and a cheese made of hard vinyl chloride that was passed through.

(See Figure 1) ■ Close the exhaust valve 11 and turn on the ventilation fan 1.
0, air fills the bag 6 in the height direction through the ventilation pipe 9 and the bag 5 in the length direction of the two tunnel sheets 4 on the left and right sides of the tunnel, and the bag 6 in the height direction is filled with air.
The tunnel expanded in the height direction from the left and right along the length of the tunnel between the outer aggregate 1 and the inner aggregate 2 to the location of the baser 3, and the tunnel was closed by the tunnel sheet 4 in about 5 minutes. It became a state.

(See Figures 2 and 3) The experimental results obtained by adding a slope to the bag 6 in the height direction in the longitudinal direction did not change. In this case, the power consumption of the sirocco fan to close the tunnel is 30
Even if the voltage of the blower fan is reduced to 1 OW after the tunnel is closed, and the power consumption is reduced to 1 OW, the tunnel will remain fully closed, so the electricity bill will be very low. ■ When the rotation of the ventilation fan 10 is stopped and the exhaust valve 11 is opened, air is passed through the ventilation pipe 9 and the bags 5 in the length direction and into the bags 6 in the height direction of the two tunnel sheets 4 on the left and right sides of the tunnel. The filled air is discharged from the exhaust valve 11, and the tunnel sheet 4 loosens and collapses into the outer aggregate 1 due to its own weight.
and the inner aggregate 2, and the tunnel was in an open state in about 7 minutes.

(See Figure 4) Furthermore, by stretching the ceiling sheet 8 with a width of 60 mm, when the tunnel is closed, rain will not get into the tunnel, and drafts will be difficult to enter, so even at a wind speed of 15 skins/second, the tunnel will be closed. It didn't break.

In another embodiment of the present invention, the inner diameter is 5 arcs and the length is 4 arcs.
One bag made of vinyl chloride with 0.05 skin thickness of 8h is placed in the fifth bag.
As shown in the figure, the length direction is 50 arc lengths, and the height direction is 68 arc lengths by alternately bending them at right angles to form a rectangular wave shape, forming a bag 5 in the length direction and a bag 6 in the height direction. with tape,
A tunnel sheet 4 was formed by pasting it on vinyl chloride having a width of lm and a length of 2h and a thickness of 0.05cm.

In the case of this embodiment, the tunnel is closed in about 3 minutes after the ventilation fan 10 is turned.
The tunnel was in an open state in about 5 minutes after stopping the operation and opening the exhaust valve 11, making it possible to open and close the tunnel more quickly. Similarly, the tunnels were opened and closed without any problems when experiments were carried out by changing the shape of the bag 5 in the length direction and the bag 6 in the height direction to have a rectangular wave shape, a triangular wave shape, a sine wave shape, and a trapezoidal wave shape.

According to the present invention as described above, there is an advantage that the tunnel can be opened and closed easily by air.

Note that the sheet material for the tunnel of the present invention may be made of rubber in addition to plastic such as vinyl chloride, and the tunnel of the present invention can be used not only for agriculture but also for warehouses and the like. Furthermore, in the present invention, (1) By electrically operating the exhaust valve 11 and the blower fan 10, even if there are multiple tunnels over a large area, one switch can be made in about 15 minutes, depending on the capacity of the blower fan 10.
