Description

[Detailed description of the invention] (a) Field of the invention This invention relates to a support device for a rotating shaft that winds up a rope that pulls the edge of the curtain when opening and closing the lining curtain stretched inside the ceiling of a greenhouse.

(b) Background of the invention The conventional support device for the above-mentioned rotating shaft is, for example,
As shown in the figure, a large metal hanging fixture 3 with approximately V-shaped sides is hung from the center 2 of the ceiling of a greenhouse 1 via a support rod 4, and ropes 6 for pulling curtains 5, 5' on both sides are attached to it. It was designed to support a rotating shaft 7 for winding.

However, the hanging tool 3 as described above is large, and as shown in FIG. The links 8 must be welded, which increases the cost, and the thickness of the upper holding frame 3a is large, so the upper and lower curtains 5,
A gap S is formed between 5', and internal heat escapes upward through this gap S.

In order to prevent such heat scattering, an auxiliary curtain 9 must be placed below the overlapping portion of the left and right curtains 5, 5', which has the disadvantage of increasing installation costs.

(c) Purpose of the invention The purpose of this invention is to provide a rotary shaft support device for opening and closing greenhouse lining curtains that can solve the above-mentioned problems.

(d) Structure of the device In this device, the upper end of a rectangular metal plate is bent downward to provide a hook portion that locks onto a greenhouse fixing pipe, and the lower portion is open below approximately the middle portion of the metal plate in the vertical direction. A hook body is provided with a plurality of engaging parts at symmetrical positions on both sides of the main body of the notch, and a recessed part is opened upward for inserting a rotating shaft for opening and closing the lining curtain. a substantially U-shaped rotating shaft support member provided with rotating shaft support rollers on the left and right inner surfaces and the bottom surface of the recessed portion, and selecting the plurality of engagement portions between the rotating shaft support member and the hook body. A rotating shaft support device for opening/closing a greenhouse lining curtain is characterized in that it is constructed of a connecting member that can be connected together.

(e) Function of the invention The rotating shaft support device for opening and closing the greenhouse lining curtain of this invention is as shown in FIG.
0 is used to support the rotating shaft 7 on one side away from the center.

Therefore, it is only necessary to provide the lining curtain support pipe 33 and the support rod 4 that supports it in the center, and both lining curtains 5, 5' are attached to the support rod 4.
Although a slight gap is created at the point, both curtains 5 and 5' are almost completely overlapped in a close contact state.

(f) Effects of the invention According to this invention, the upper end of the rectangular metal plate is bent downward to provide a hook part that locks to the greenhouse fixing pipe, and the lower part of the metal plate is provided with a hook part below approximately the middle part in the vertical direction. Create a vertical notch that opens the
Both sides of the main body of the notch are provided with a hook main body having a plurality of engagement parts provided at symmetrical positions, and a recessed part that opens upward for inserting a rotating shaft for opening and closing the lining curtain, and the left and right inner surfaces of the recessed part and a substantially U-shaped rotating shaft supporting member with a rotating shaft supporting roller provided on the bottom surface; and a connecting member capable of connecting the rotating shaft supporting member to the hook main body by selecting the plurality of engagement portions. It has a simple structure, eliminates the need for the expensive hanging tool 3 mentioned above, and allows the user to freely select the mounting position of the rotating shaft support member relative to the hook body, thereby adjusting the height of the rotating shaft. can be adjusted and set to the optimal height according to the operator.

(g) Example of the invention An example of the invention will be described below in detail based on the drawings.

The drawings show the rotary shaft support device for opening and closing the greenhouse lining curtain of this invention, and FIG. The rotary shaft supporting member 12 is capable of supporting the rotary shaft, and these two are connected by a connecting fitting 13 as a connecting member.

The hook main body 11 has an upper part bent to form a hook part 14 for engaging and hanging an outer circumferential pipe 30 constituting a plastic greenhouse, and the bent piece 14a and the upper part of the main body have opposite left and right hook parts 14, respectively. A pair of through holes 15 and 16 are provided, and wedges 17 are driven into these through holes 15 and 16 to be held between the outer circumferential pipe 30 as described above.

The hook body 11 also has a notch 1 in the vertical direction that opens at the lower part from the upper and lower intermediate parts.
8, and a plurality of engagement holes 19, 20 forming engagement portions are provided at appropriate intervals on both sides 11a, 11b of the main body, respectively.

The rotating shaft support member 12 has two metal plates connected at one side facing each other to form a substantially U-shaped front view, with a recess 35 open at the top formed in the center, and a recess 35 at the upper end. provides engagement holes 21, 22, and selects the engagement holes 21, 22 and the plurality of engagement holes 19, 20 of the hook body to face each other by setting the vertical length of the entire device; Connecting fittings 13
is inserted and fixed from the back side with thumbscrews 23.

Between the two metal plates of this rotary shaft support member 12, rotary shaft support rollers 24, 25, 26 protruding from the side frames of the recessed portion 35 are provided on both side frames and the lower frame, respectively.
are provided, and the rotating shaft 7 is supported by these three support rollers.

In the above embodiment, the engaging portion of the hook main body 11 is composed of a plurality of engaging holes 19, 20 separated by an appropriate distance, but the invention is not limited to this. For example, protrusions may be provided at appropriate intervals on the inner surfaces of both sides. It may also be configured by a pair of elongated holes.

The use of the rotary shaft support device 10 for opening and closing greenhouse lining curtains of this invention having such a configuration will be explained based on FIGS. 4 and 5. After setting the installation position to the greenhouse outer frame pipe 30
The rotary shaft 7 is suspended through a hook portion 14 at a position lower than the center of the support member 12, and supports the rotary shaft 7 inserted into the support member 12.

A carriage 31 for rotating the rotating shaft 7 is attached to one end of the rotating shaft 7, and both ends of a curtain tensioning rope 6 connecting the side edges of both lining curtains 5, 5' in the middle are wound around it. ing.

In addition, 4 in the figure is a support rod suspended from the center part of the outer frame pipe 30, and the inner curtain support pipe 33 which constitutes the top twill line of the inner curtain at the lower end
is supported.

Further, numeral 34 in the figure indicates a guide pulley for the rope 6.

Now, if you rotate the carriage 31 clockwise,
As one side of the rope 6 is unwound and the other side is wound up, the side edges of the lining curtains 5, 5' connected in the middle of the reciprocating rope are drawn toward the center.

When the carriage 31 is further rotated, the side edges of the lining curtains 5, 5' on both sides completely overlap with each other, except for the support rod 4, as shown in FIG.

When removing the inner curtains 5 and 5', rotate the carriage 31 counterclockwise, and one side will unwind the rope 6, and the other will be wound up, so that it is tied in the middle of the reciprocating rope. The curtains 5, 5' are pulled apart to both sides of the greenhouse, as shown in FIG.

In this way, by using the support device of this invention, there is no need for the auxiliary curtain 9 to close the gap, there is no need for the expensive hanging tool 3 as in the conventional case, and the mounting position of the rotating shaft support member 12 can be set arbitrarily. You can select and adjust the height of the rotating shaft 7.
