Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing device for a greenhouse, more specifically,
This invention relates to an electric side opening/closing device for a vinyl greenhouse that electrically opens and closes the side vinyl of the greenhouse in accordance with the temperature inside the greenhouse.

[Conventional technology]

Traditionally, automatic window opening/closing devices for greenhouses have been popular;
Generally, the side opening and closing of a vinyl greenhouse was carried out by manually lifting the vinyl by directly grasping its hem, or by rolling it up using a simple hoist with a hand handle.

In addition, in some electrically operated surfaces, for example, the drive motor moves up and down as the side vinyl is rolled up and unwinded, but since the motor part moves up and down along with the cord, the motor part has to be exposed outside. However, it has not been put into practical use because it is difficult to avoid electrical leakage due to rain, etc.

[Problem that the invention seeks to solve]

The present invention solves the inefficiency of conventional manual opening/closing and the drawbacks of the motorized vertical opening/closing device, provides a device that can electrically and automatically open/close the side of a greenhouse, and improves the efficiency of work within the facility. The aim is to make it unmanned.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention uses an electronic motor with a brake, a power transmission means, a pipe connected in parallel by a plurality of wires, and a vinyl sheet suspended from the lower pipe. It is configured to electrically raise and lower the vinyl on the side of the greenhouse, and by incorporating an electronic thermostat, opening sensor, or controller into the above combination, it can be adjusted according to the temperature inside the greenhouse. The site is configured to open and close automatically.

In the device of the present invention, by appropriately selecting the control means, it is possible to operate the opening/closing devices provided on both sides of the greenhouse in synchronization or to operate them separately and independently.

〔Example〕

Hereinafter, an example of a side opening/closing device for a greenhouse using the device of the present invention will be described with reference to the drawings.

In the embodiment shown in FIG. 1, opening and closing devices are provided on both sides of the greenhouse, but since these devices have exactly the same structure and function, only the device on one side will be described.

At the top of the side of the greenhouse, a first pipe, ie, a wire winding pipe I, is arranged substantially horizontally. As shown in detail in FIG. 2, this wire winding pipe 1 is connected to a motor gear head 2a through a gear IC by means of a gear 1a and a chain 1b. This motor gear head 2a is directly connected to an electronic motor 2 with a TL (m brake).

A frame plate 14 is fixed to the pillars 8 on each side of the greenhouse, and a motor gear head 2a, an electronic motor 2, a gear 1
c is supported by this frame plate 14.

In order to prevent the wire winding repipe 1 from deflecting and to rotate the wire winding repipe 1 smoothly, bearings 3 for rotatably supporting the wire winding pipe are provided in each branch 12 other than on both sides of the house. There is.

As shown in FIGS. 2 and 4, fittings 16 for the eaves of vinyl roofing are provided at regular intervals on the frame 17 in the horizontal direction of the ceiling. By extending the eaves of
It is preferable to form an eaves to cover the gap between the pipe 1, the bearing 3, and the side ceiling.

This fitting 16 may be in the shape of a three-shape as shown in the figure or in the form of a straight rod on the vehicle, but at least the pipe 1
It needs to be long enough to cover the bearing 3 sufficiently.

Nine wires of a fixed length are fixed to the pipe 1 at fixed intervals, and a second pipe 13 is attached to the other end of the wire.

A longitudinal edge of a vinyl sheet of a certain width is fixed to the pipe 13, and the opposite edge of the vinyl sheet is fixed to the lower end 10 of the house by suitable means.

The electronic motor 2 with an electromagnetic brake performs forward and reverse rotation and stops according to commands from the seedling-raising robot 6, and rotates the wire winding pipe 1 in the forward and reverse directions via the motor gear head 2a gear IC, chain lb, and vibe side gear 1a. , to stop. By winding and unwinding the wire, the pipe 13
moves up and down, and the vinyl sheet also moves up and down accordingly, changing the side area covered by the vinyl sheet. In other words, the sides can be opened and closed.

That is, as the first pipe I rotates, the wire 4 is wound around the pipe 1, and the vinyl sheet 14 is thereby pulled upward through the second pipe I3, so that the vinyl sheet covers the sides. Closed.

By rotating the pipe 1 in the opposite direction, the wire 4 is automatically and smoothly unwound by the weight of the second pipe 13 and the vinyl sheet 14, and the wire 4 is unwound automatically and smoothly.
3 and the vinyl sheet 14 are lowered and the sides are opened.

When the sides of the house are opened, loose vinyl sheets are placed in a pile at the base of the house (this condition is not shown). It is convenient to provide it at the base.

Furthermore, a guide means may be provided for aligning the winding position of the wire 4 when the wire 4 is wound around the first pipe.

An electromagnetic switch 9 provided near the motor 2 turns on current according to a command from the seedling-raising robot 6.

In FIG. 1, a sensor (microswitch) 7 for sensing the side opening ratio is provided on the central pillar 12 on the front side.

Whether this sensor is provided only on one of the two sides or on both sides may be appropriately selected depending on whether the opening/closing devices on both sides are operated in synchronization or individually.

The robot 6 is equipped with an electronic thermostat for detecting the temperature inside the greenhouse and setting the opening degree of the side according to the detected temperature.

In the side opening/closing device configured as described above, when the rotational speed of the 40W electronic motor with electromagnetic brake is 1250 rpm, the reduction ratio of the gear head is 100, and the outer diameter of the winding pipe is 22 mm, the rising speed is 1. 5C111/sec, maximum rotational winding torque was 3Qkg.

Furthermore, by turning on the manual button of the electromagnetic opening/closing 1lS9, the side can be opened/closed artificially.

Furthermore, in combination with a timer, it is possible to freely open and close the sides at any time.

〔Effect of the invention〕

As mentioned above, the present invention can electrically and automatically open and close the side of the greenhouse, making it possible to open and close the side at a high position where it is impossible for workers to cultivate hills. Farmers can be relieved from their duties.

It also has advantages such as a simple structure and low installation cost.
