[Prior Art] Expectations for efficient agricultural management with a high cash conversion rate,
Against the backdrop of responding to the new era of liberalization of agricultural products, field farms are actively adopting forcible cultivation of various agricultural products, and fruit-growing farmers also use high-quality fruit as a countermeasure against imported fruits. The introduction of rain avoidance facilities for harvesting is encouraged. As a means for avoiding these forced cultivations and rain, the most economical and easy-to-manage pipe house (or vinyl house), that is, a large number of steel pipes curved in an arc are juxtaposed at predetermined intervals, and they are used as a skeleton for plastics. A simple tunnel-like building is used with a rain-prevention sheet made of stainless steel.

The height of this pipe house varies greatly depending on its use. For example, from the extremely low-rise pipe house used for covering each ridge of the field, it is often adopted for the purpose of forcing cultivation of flowers and the like. Is tall enough to reach if you reach out, and extremely tall enough to cover the entire fruit tree that is often used in cherry orchards, etc. There are even the longest ones. Your height is
In facilities below that people can reach from the ground, there is no problem in installing rain-prevention sheets on the skeleton, but it is extremely tall used in orchards. For tall ones, the skeleton itself is also very weak, so when workers try to climb with the skeleton as a scaffold, it is quite dangerous, and if it is a long one, it will carry rain. Since the weight of the avoiding sheet becomes considerable and the danger level increases, fruit tree farmers are reluctant to use this sheeting work. Helped with reasons such as having to rely on workers and female workers,
There are many farmers who have been unavoidably asked to use a seating specialist, and even if that is not the case, it is an extremely inconvenient situation for farmers who are forced to increase the cost burden due to the cost of introducing the facility.

The present invention is based on the above circumstances.
Especially for pipe houses with a new structure that enables safe and easy delivery of rain-prevention sheets to pipe houses where it is difficult to send rain-prevention sheets to the skeleton while workers are on the ground. We worked on the development and research of the rain avoidance sheet feeding device, and finally came here to obtain the results, and the details of the configuration will be explained below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be understood from the examples of the respective drawings shown as typical embodiments, the rain shelter sheet feeding device for a pipe house of the present invention basically has the following structure. is there. That is, an open leg member having an attachment metal fitting at the lower end, which is adjustable in expansion and contraction, a rotary drum supported by the open leg member at a predetermined distance above a gate type pipe frame of a pipe house in a substantially horizontal shape, and an open leg On the member, it is composed of an upper frame member also serving as a seat separation prevention frame which is arranged so as to straddle over the rotary drum, and the upper frame member is used for inserting a latent wire through which the sheet pressing lines of the pipe house are collectively floated. It is a rain shelter sheet feeding device for a pipe house having a guide hole.

The open leg member is most preferably an aluminum pipe in consideration of its strength and weight reduction, but a strong plastic pipe or the like can be used, and pipe materials having different diameters can be combined. The entire length can be freely expanded and contracted and adjusted. Then, three or four are combined so that a rotating drum described later can be supported substantially horizontally above the gate type pipe frame by a predetermined distance, and each upper end side is a shaft mounting portion, and the lower end side is a gate type. In order to be able to mount, fix, and easily remove the pipe frame, a known appropriate attachment fitting, for example, a screw-in fitting attachment fitting, or the like is incorporated.

The rotating drum is a state in which rain-preventing sheets each having a length equal to or longer than the length of the pipe house and having a predetermined width are appropriately folded in the width direction into a bundle so that they can be easily spread, and the rain-shielding sheet is installed from one end of the pipe house. It functions as a kind of track for pulling up one end side and sending it smoothly to the other wife side, and is supported by the above-mentioned leg members in a substantially horizontal shape to avoid rain in a bundle. The structure must be such that it smoothly rotates as the seat moves.
The shape of the rotating drum can be a drum in which a collar-shaped disk is integrated on both sides of a cylindrical body, or a drum-shaped drum with the center constricted. Then, it is desirable to use plastic or aluminum as much as possible, but in some cases, it is also possible to use thin steel plate.

The upper frame member surrounds the rotary drum from both sides upward, and functions to prevent the rain-preventing sheet in a bundle moving on the rotary drum from being laterally displaced by something. It also functions as a gripping part when it is lifted up to a predetermined position of the pipe house, and also functions as a frame member for providing a guide hole for inserting a latent wire, which will be described later. The left and right drums each have a reverse "U" shape in which they are connected by extending further upward from their upper end shaft-attached portions, or either the left or right open leg member is further raised from the upper end axle-attached portion. Curved and extended over the rotating drum and lowered to the opposite end of the open leg member near the pivoted portion, or alternatively they may be formed as an extension of the open leg member. age Rather, it is formed as a separate member, and is formed so as to be connected and fixed to the upper end of the leg opening member by an appropriate means, that is, the structure itself cannot change its posture, The leg member may be formed as a member separate from the leg member, and the angle of the leg member can be changed by axial attachment or other means.

The upper frame member also has a structure in which the function of enclosing it from both sides of the rotary drum upward can be opened at any time, for example, a structure which can be easily removed from the upper end portion of the opening leg member, or the frame member. The structure is such that only a part can be opened in a single-opening manner, or a part of a predetermined length can be removed, and after the rainproof sheet in a bundle state is completely lifted to a predetermined place of the pipe house, It would be extremely convenient if a structure was adopted that allows the work for removing the feeding device to be carried out easily.

Further, when a guide hole for inserting a latent wire is formed in an appropriate position of the upper frame member (provided that it is above or outside the rain-preventing sheet in a bundle moving on the rotating drum). There is. In other words, except for new pipe houses, before the rain-prevention sheet is stretched, the sheet-holding wire rod is stretched around the gate-type pipe frame, which is the skeleton, in a state in which the rain-prevention sheet is pinned along the skeleton. (Plastic strip, commonly known as mica wire)
However, in order to perform the same function again in the next season, it is a normal state that they are laid over in the direction of the beams with a predetermined interval left therebetween. Therefore, if the rain-preventing sheet in a bundle state is guided and lifted on the rotating drum in this state, the sheet pressing wire will be positioned below the rain-preventing sheet. Before carrying them up, it is necessary to raise the sheet retaining wire rods that have been left behind together so that the rain-preventing sheet in a bundle can sneak under the sheet retaining wire rod.
It is the submerged wire that fulfills the function of lifting the sheet pressing wire above the skeleton of the pipe house by a predetermined distance, and the subwire is placed in a proper position on the upper frame material so as to support the wire at a predetermined height position. A guide hole for inserting and supporting is formed.
