Description

[Detailed description of the invention] Industrial field of application This invention is used to move a tea garden management device used for picking tea leaves, pruning tea branches, pruning, and other various management tasks in a tea garden, as shown in Fig. 2. This relates to the track b of the tea garden management device installed approximately parallel to the tea row a in the path between the tea rows a and a, and more specifically, the tea garden management device is installed at the end of the track to the adjacent tea garden. This invention relates to a track for a tea garden management device that has been improved to have a structure that allows the length required for relocation to a ridge to be expanded and contracted.

Conventional technology Regarding tea plantation management equipment, for example,
As described in the specification and drawings of No. 141548, a resin-coated metal tube is manufactured by coating the outer periphery of a thin-walled steel tube with AAS resin or the like in a thin, uniform layer to have an outer diameter of ψ28 or ψ32, and is also made of synthetic resin. It is assembled as a lightweight gate-shaped frame that straddles the tea furrow using wooden joints, and is equipped with the necessary management machinery. It is designed to be driven and moved.

Conventionally, a resin-coated metal tube of ψ32 mm has been used as a rail material for the track b of a tea plantation management device because it has excellent corrosion resistance, is lightweight, and has appropriate strength and rigidity.

By the way, when the tea garden management device has been moved from one end of tea furrow a to the other for management work, it is necessary to move it to the next adjacent tea furrow. In order to make this relocation work easier for one person, as shown in Figure 6, the track b is further extended by about 1.5 m from the end of the tea furrow a, and the tea garden management equipment is placed on this extended track part c. Pull it out, leave one leg on track b and use it as a turning fulcrum, lift the leg on the other side, and move it around to the extension track c of adjacent track b, as if rotating it, and place it on top of it. It is assumed that

For this reason, conventionally, the trajectory b of tea garden management equipment
It is said that an extension track section c of about 1.5 m is essential at both ends.

Problems to be Solved by the Present Invention As is clear from FIG. 1, the track b of the tea garden management device is laid at a height of about 10 cm above the ground. Therefore, in the area where the extended track section c has been laid, workers also have to walk across the extended track section c one by one, and if they walk on their backs, they may hit their feet on track b or trip over track b and fall. It was dangerous.

Of course, it is impossible to pass agricultural vehicles, cultivators, carts, etc. in the area of the extended track section c, and in order to allow these to pass, the extended track section c is
There was a problem in that it was necessary to prepare a passage d on the outside of the tea garden, which limited the effective cultivation area of the tea garden.

Means for Solving the Problems As a means for solving the above-mentioned conventional problems, the trajectory of the tea garden management device according to this invention is as shown in a preferred embodiment in Figs. 1 to 5 of the drawings. , in a track on which a tea garden management device runs, which is made of tubular rail material, is laid approximately parallel to the passage between the tea ridges along the tea ridges, and has a structure that straddles the tea ridges, the track is configured at the end of the track b. A tubular auxiliary rail 2 is inserted into the hollow part of a tubular main rail material 1 and is extendable and retractable to a required length for the telescope. Legs 5 that maintain approximately the same track height as the main rail material 1 are provided at the tip of the auxiliary rail 2, and a cap 8 is attached to the main rail material to waterproof the fitting part when the auxiliary rail material 2 is stored. 1 or the end of the auxiliary rail 2.

Function The auxiliary rail 2 is pushed into the main rail material 1 and stored when not in use. Only when necessary, by pulling out the auxiliary rail 2 long and standing the leg 5 at its tip, the tea garden management device can be moved between the tea rows a, a.

When the auxiliary rail 2 is pushed into the main rail material 1 and stored, the fitting portion of both rail materials is waterproofed by the seal cap 8 to prevent rainwater etc. from entering into the main rail material 1. .

Example Next, the illustrated embodiment will be described.

Figure 1 shows the structure of the end of the track of the tea plantation management device. In the figure, 1 is the main rail material, 2 is the auxiliary rail, and the outer peripheral surface of each thin-walled steel pipe is made of weather-resistant AAS resin. coated in a thin, uniform layer,
A resin-coated metal tube whose inner surface is coated with anti-rust paint is used as the rail material. As the main rail material 1, a resin-coated metal tube with an outer diameter of ψ32 and an inner diameter of about ψ29 is used, and for the auxiliary rail 2, a resin-coated metal tube with an outer diameter of ψ28 is used.
The auxiliary rail 2 is inserted into the hollow part of the main rail material 1 and is telescopically telescopically expandable. The length of the auxiliary rail 2 is approximately 2m,
The effective length of about 1.5m required as an auxiliary rail can be pulled out (extended).

A cap 3 for waterproofing the cutting opening (tube end opening) is fitted onto the tip of the auxiliary rail 2 and is bonded watertightly. Further, a T-shaped joint 4 is attached and glued to the auxiliary rail 2 at an inward position of the cap 3, and a vertically downwardly directed leg 5 is attached to this. A resin-coated metal tube is also used as the leg 5, which is glued to the socket of the T-shaped joint 4. Further, a cap 6 is fitted and bonded to the lower end of the leg 5 to waterproof the tube end opening. The auxiliary rail 2 is placed on the ground 7 by legs 5 at approximately the same height as the main rail material 1 (approximately 10
cm).

A seal cap 8 made of synthetic rubber such as silicone rubber with good weather resistance is attached to the auxiliary rail 2 at an inward position of the T-shaped joint 4. The seal cap 8 has an approximately cylindrical shape, with approximately half of the main rail material 1 side having a slightly larger diameter when viewed in the axial direction.
A fitting portion 8a is formed on the inner diameter surface of the gap where the main rail material 1 is closely fitted into the outer circumferential surface of the auxiliary rail 2.
is formed.

That is, when the auxiliary rail 2 is pushed into the main rail material 1 and stored when not in use, the pipe end portion of the main rail material 1 is finally tightly fitted into the fitting portion 8a of the seal cap 8. Therefore, the pipe end portion of the main rail material 1 is covered with the seal cap 8 to prevent rainwater from entering, preventing rainwater from entering the main rail material 1 and rusting and corrosion of the steel pipe portion exposed at the pipe end. is prevented as much as possible.

Thus, according to the present invention, the end of the track b of the main rail material 1 can be made approximately the same length as the tea furrow a, as the overall view of the tea garden management device is shown in FIG. The outer side of the end of the brown furrow a can be made into a passage d. That is, only when the tea garden management device is to be relocated to an adjacent tea furrow, the auxiliary rail 2 is pulled out onto the path d from the end of the corresponding track b and is used for relocating the tea garden management device. Conversely, unused or unnecessary auxiliary rails 2
... can all be pushed into the main rail material 1 that constitutes the track b, so naturally there will be no obstructions caused by the track on the path d, which will not impede the passage of people, vehicles, etc. .

Different Embodiment (Part 1) When the auxiliary rail 2 is erected by the legs 5, as shown in FIG.
A configuration in which a type joint 10 is attached and an installation pipe 11 in a direction perpendicular to the auxiliary rail 2 is attached to the T-type joint 10, or a configuration in which a circular installation plate 12 is attached to the lower end of the leg 5 as shown in FIG. This not only increases the ground contact area but also increases the stability against the falling of the auxiliary rail 2.

(Part 2) As shown in Fig. 5, the seal cap 8 can be installed at the pipe end of the main rail material 1, thereby making the fitting part of both rail materials 1 and 2 waterproof. can.

Effects of the present invention As described above in detail together with the embodiments, according to the trajectory of the tea garden management device according to this invention, the extended track portion (see Fig. 6) required for relocation of the tea garden management device (see c) in the middle is provided, and no dedicated space is required for the extended track section (compare Figures 2 and 6), thus increasing the effective cultivation area of the tea plantation. . This allows for smooth passage of people, vehicles, etc., and improves safety.
