The steady rest device 5 is provided on the other end side. The effect by this steady rest apparatus 5 is demonstrated using the comparative example shown in FIG.

  In the agricultural equipment 101 of the comparative example shown in FIG. 8, the steadying device 5 is not provided on the winding shaft 31. Since the winding shaft 31 is rotated by the driving device 4 provided on one end side, when the winding shaft 31 winds up the curtain 3, the tension that the winding shaft 31 acts on the curtain 3 is increased. The one end side differs from the other end side. In the axial direction of the take-up shaft 31, the take-up shaft 31 has a tension applied to the curtain 3 by one end of the take-up shaft 31 provided with the driving device 4, and the other end of the take-up shaft 31 acts on the curtain 3. Stronger than tension. In other words, in the axial direction of the winding shaft 31, the winding shaft 31 has a weak tension that acts on the curtain 3 on the side opposite to the driving device 4. Therefore, on the winding shaft 31 on the side opposite to the driving device 4, the curtain 3 is loosely wound, and the winding amount of the curtain 3 per rotation of the winding shaft 31 may increase. That is, in the axial direction of the winding shaft 31, the winding amount of the curtain 3 is different, and thus there is a possibility that winding deviation occurs. Thereby, as shown in FIG. 8, the winding shaft 31 is inclined so that the other end side opposite to the driving device 4 is higher than the one end side where the driving device 4 is provided, and the curtain 3 is smooth. Opening and closing may be difficult.

  On the other hand, as shown in FIG. 9, the agricultural facility 1 of the present embodiment is provided with a drive device 4 on one end side in the axial direction of the take-up shaft 31 and a weight 51 as a steady rest device 5 on the other end side. It has been. Due to the weight of the weight 51, the winding shaft 31 has a strong tension acting on the curtain 3 on the side opposite to the driving device 4. Therefore, the difference in tension applied to the curtain 3 is reduced between the one end side and the other end side in the axial direction of the winding shaft 31, and the winding shaft 31 is kept horizontal. Thereby, in the axial direction of the winding shaft 31, the winding amount of the curtain 3 becomes substantially equal, the occurrence of winding deviation of the curtain 3 is suppressed, and the curtain 3 can be smoothly opened and closed.

  Similarly to the curtain 3, the side curtain 6 is provided with the steadying device 5 a on the winding shaft 61 attached to the lower end 60, so that the side curtain 6 can be opened and closed smoothly. Become.

Furthermore, the coupling members 25A, 25B, and 25C that couple the frame 2 and the second connection frame 24 are configured so that the amount of protrusion from the frame 2 toward the outside is small (for example, the amount of protrusion is 1 cm or less). Thereby, it becomes easy to move the lower end part 30 of the curtain 3 along the outside of the frame 2 without the curtain 3 being caught while the lower end part 30 of the curtain 3 is moving, and the curtain 3 can be opened and closed more smoothly. Become.

  Moreover, although the curtain 3 of this embodiment is fixed to the top part 20 of the flame | frame 2, and it is comprised so that it may open and close by the lower end part 30 moving, it is not restricted to this structure. For example, the lower end 30 of the curtain 3 may be fixed with respect to the frame 2, and the curtain 3 may be configured to open and close when the upper end moves along the frame 2.

  In the present embodiment, the driving device 4 is provided only on one side of the winding shaft 31 in the axial direction. However, the driving device 4 may be provided on both sides of the winding shaft 31 in the axial direction. In this case, it is preferable to rotate the winding shaft 31 in synchronization with the drive devices 4 on both sides in the axial direction of the winding shaft 31. Thereby, in the axial direction of the winding shaft 31, the difference in tension that the winding shaft 31 acts on the curtain 3 is reduced and the occurrence of winding deviation is suppressed, so that the curtain 3 can be opened and closed smoothly. .

  The belt-like member 52 of the present embodiment is formed of a resin film-like member (for example, a polyolefin film), a net-like member, etc., similar to the curtain 3, and is opposite to the drive device 4 with respect to the winding shaft 31. It is provided at the end. The belt-like member 52 has the Y-axis direction as the width direction, the upper end portion 53 is attached to the take-up shaft 31, and the lower end portion 54 is attached to the fixed shaft 55. The fixed shaft 55 is fixed to the column portions 21 of the plurality of frames 2 with the Y-axis direction as the axial direction. Further, the belt-like member 52 is wound around the winding shaft 31 in the direction opposite to the curtain 3 so as to be stretched along the frame 2. That is, when the winding shaft 31 rotates in the direction to wind up the curtain 3, the belt-like member 52 is fed out from the winding shaft 31, and when the winding shaft 31 rotates in the direction of feeding out the curtain 3, the belt-like member 52 is wound up. It is wound around the take-up shaft 31.

  With the above configuration, when the winding shaft 31 winds up the curtain 3, the end of the winding shaft 31 on the side opposite to the driving device 4 is not higher than the end on the driving device 4 side. The winding shaft 31 is kept horizontal. Thereby, in the axial direction of the winding shaft 31, the winding amount of the curtain 3 becomes substantially equal, the occurrence of winding deviation of the curtain 3 is suppressed, and the curtain 3 can be smoothly opened and closed.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
