Description

[Detailed explanation of the invention] Industrial application field This invention involves cultivating tea plants on a large scale in large fields in multiple rows, and by laying rails along the paths between the tea rows, each tea row is In the field of tea cultivation, where various management tasks such as picking tea leaves, trimming, and pruning are carried out by running a tea garden management device that straddles two rails on both sides, this track-type tea garden management device is used on two rails on both sides. The present invention relates to a ridge moving trolley of a track type tea garden management device, which is used as a means for moving the management device onto the rail of an adjacent or next tea ridge when it reaches the terminal end.

Conventional technology In the past, one rail was laid in each path between the tea furrows, and a tea garden management device was run that straddled the two rails located in the path on both sides of the tea furrows to pick tea leaves, trim the branches, etc. A track-type tea garden management device for performing various management operations such as pruning is publicly known (for example, Japanese Utility Model Application Publication No. 48432/1983, Japanese Utility Model Application No. 101033/1987, etc.).

Conventionally, as a means for moving these known track-type tea garden management devices onto the rail of an adjacent tea ridge at the terminal end of the rail, as illustrated in FIG. (traveling platform) b
is provided with a vertically upward rotating shaft c, and this rotating shaft c is rotatably supported by a bearing h on the upper leg d on the gantry g side, and a clamp e fixedly attached to the lower leg b is attached to the upper leg d on the gantry g side. A fastened and fixed configuration is adopted.

In other words, when this track-type tea garden management device reaches the end of the rail f and is to be moved onto the rail of the adjacent tea ridge, first the legs on the side of the ridge to which the management device is to be moved are first moved. The clamp e is released only for the upper and lower legs b and d, and the upper and lower legs b and d are allowed to rotate about the rotation axis c. Then, the worker grasps the leg on the opposite side with both hands, walks around the axis of rotation c by about 180°, and moves the rail wheel a of the leg on the side held in his hand to the next leg. The relocation is carried out by placing it on the rail f (see Japanese Utility Model Application Publication No. 101033/1983).

Problems to be Solved by the Present Invention In the conventional relocation method described above, the structure of the legs b, c, d, e, and h of the tea garden management device becomes quite complicated, and the design and manufacture thereof are difficult and time-consuming. , it ends up being expensive.

Moreover, it is difficult to secure the structural integrity between the lower leg b and the upper leg d on the side of the pedestal g by simply tightening and fixing with the clamp e. As a result, the strength and rigidity of the legs of the management device are inevitably inferior, and the device is likely to be used in an unstable state where the footing is unsteady, giving a sense of uneasiness during use, which is undesirable.

Furthermore, the work in which the worker grasps one leg with both hands and moves the other leg by walking and turning about 180 degrees around the axis of rotation c of the opposite leg means that the footing is inherently poor. Since the work is done on a farmland, there is a risk of tripping or falling. If a worker falls during the relocation work, there is a risk that the management device will fall along with it, so these are issues that need to be resolved.

Means for Solving the Problems As a means for solving the problems of the above-mentioned prior art, the ridge moving trolley of the track-type tea garden management device according to this invention is a preferred embodiment shown in FIGS. 1 to 4 of the drawings. As shown, it is a cart equipped with swivel casters 2 that run on the ground 1, and on the platform 3 there are brown ridges 4, 4.
A substantially horizontal auxiliary rail 6 is provided at substantially the same height as the main rail 5 laid in the passage between the two.
The auxiliary rail 6 is made longer than the distance between the wheels 8, 8 in the longitudinal direction of the track-type tea garden management device 7, and
A dead end stopper 9 of the tea garden management device 7 is provided at one end of the auxiliary rail 6 or in the vicinity thereof.

Then, the auxiliary rail 6 is connected to the terminal end of the main rail 5.
The trolleys 12 are arranged so that the rails 5 and 6 are connected in a series in the same direction, and both rails 5 and 6 are connected with a flexible pipe 10, so that the track-type tea garden management device 7 can move back and forth between the main rail 5 and the auxiliary rail 6. to let;
and a management device 7 mounted on the auxiliary rail 6
The rails 5 and 6 are disconnected by the flexible pipe 10 and the tea garden management device 7 is moved to the adjacent or next tea furrow 4 by running the swivel casters 2.
It is characterized by horizontal movement to .

In addition, the above-mentioned ridge moving cart 12 is also characterized in that it consists of a total of two units, one separated and independent for each permanent rail 5.

Function This ridge moving trolley 12 can be freely lightly pushed or pulled in any direction on the ground 1 of the tea plantation by running the swivel casters 2, regardless of the distance to which it is moved.

Even if there is a slight difference in height between the main rail 5 and the auxiliary rail 6 due to the way the tea fields are cultivated, both rails 5 and 6 can be easily connected in series using the flexible pipe 10, and both rails 5 , 6, there is no problem in the movement of the tea garden management device 7 between the two.

When the tea plantation management device 7 rides onto the auxiliary rail 6 of the trolley 12, the dead end stopper 9 prevents the tea garden management device 7 from overrunning. Alternatively, the position of the tea garden management device 7 on the trolley 12 can be restrained by connecting the tea garden management device 7 to the dead end stopper 9 using the connector 13.

Remove the flexible pipe 10 and remove the rails 5 and 6.
When the connection is released, the tea garden management device 7 mounted on the auxiliary rail 6 can be moved laterally to the desired position along with the trolley 12 by pushing or pulling it laterally as it is.

Therefore, the tea furrow 4 that we would like to perform management work on next
Park the trolley 12 at a position where the main rails 5, 5 and the auxiliary rails 6, 6 on both sides meet a series of relationships,
When the main rail 5 and the auxiliary rail 6 are connected in series with the flexible pipe 10, the tea garden management device 7 is immediately mounted on the main rails 5, 5, and the purpose of relocation can be achieved.

If the trolley 12 is configured to have only one auxiliary rail 6 and consist of two separate and independent units, one for each main rail 5, the track of the main rails 5, 5. Easy to deal with width errors and changes.

Example Next, the illustrated embodiment of the present invention will be described.

FIG. 1 shows a tea garden management device 7 that has reached the end of the main rails 5, 5 laid on the ground of the tea ridge 4 and the passage on both sides thereof, and a ridge moving trolley 12 that is separated into two independent units. 12 indicates the waiting state,
FIG. 2 shows the detailed structure of the ridge moving trolley 12.

The ridge moving trolley 12 has a short and extremely simple structure in which four swivel casters 2 are attached to the bottom of the platform 3 so that it can run on the ground 1. Although the illustrated example of the stand 3 has a framework made of pipe materials and joints, the structure is not limited to this. It may be a platform having a flat plate shape or other structure.

On the platform 3, one auxiliary rail 6 is installed approximately horizontally so as to be at approximately the same height as the main rail 5 laid on the ground 1 along the path between the brown furrows 4, 4. is set up. By the way, the main rail 5 is usually laid at a height of about 10 cm above the ground, so the platform 3 should also be made as low as possible, and the auxiliary rail 5 should be placed at the same height as the main rail 5. I am making it possible to install it. As with the main rail 5, the auxiliary rail 6 is made of a thin-walled steel pipe whose outer periphery is coated with a thin, uniform layer of synthetic resin to have an outer diameter of approximately 28 to 38 dia.

As shown in FIGS. 3 and 4, the length of this auxiliary rail 6 is longer than the distance between the front and rear wheels 8, 8 of the tea garden management device 7 mounted on the auxiliary rail 6.
The tea garden management device 7 should be about 10 cm long.
can completely ride on top of the auxiliary rail 6. One end 6a of the auxiliary rail 6 protrudes from the outer edge of the platform 3 by a length of several centimeters to several tens of centimeters, making it easy to connect it in series with the main rail 6 using the flexible pipe 10. There is. At the opposite end of the auxiliary rail 6, a rod-shaped dead end stopper 9 is erected vertically upward at a height of about 10-odd centimeters. The wheels 8 of the tea plantation management device 7 riding on the auxiliary rail 6 hit the dead end stopper 9 and are prevented from overrunning. The tea garden management device 7 mounted on the auxiliary rail 6 is
As shown in FIGS. 3 and 4, the lower leg frame and the dead end stopper 9 are connected (bound) with a connecting device 13 such as a band, annular body, or string, thereby restraining the tea garden management device 7 on the trolley 12. This is said to prevent wobbling during horizontal movement.

The ridge moving trolley 12 has the swivel casters 2 equipped with brakes, and the stopped position can be fixed by applying the brakes. It is supposed to be inserted and fixed at the stopping position.

Therefore, as shown in Fig. 1, the tea garden management device 7 reaches the end of one tea furrow 4 and the main rails 5, 5 laid in the passage on both sides thereof, and transfers it to the adjacent or next tea furrow 4. When it is necessary to move the ridge moving carts 12, 12 one by one to the end positions of the two main rails 5, 5, each auxiliary rail 6
The arrangement of the trolley 12 is adjusted so that the rails 12 are aligned in the same direction as the terminal end of the main rail 5. Then, both rails 5 and 6 are connected in series with a flexible pipe 10, and in this state, a peg 14 is driven into the ground 1 to fix the position of the cart 12. Therefore, the flexible pipe 10 only needs to be long enough to allow the rail connection work as shown in FIG. 2; if it is too long, it will become difficult to use.

Thereafter, the tea garden management device 7 is pulled or pushed by hand to drive its wheels 8, 8 from the main rail 5 onto the auxiliary rail 6 (that is, onto the trolley 12). Then, as shown in Figures 3 and 4, the tea garden management device 7
are tied to the dead end stopper 9 using the connector 13.
After that, pull out the flexible pipe 10 and remove the rail 5.
and 6, the tea garden management device 7 is manually pushed or pulled horizontally by a worker in a direction perpendicular to the rail as shown in FIG. It is moved laterally to the position of the target brown ridge 4 (main rail 5 at the target position).

At the stage where the main rails 5, 5 at the target position and the auxiliary rails 6, 6 of the two tea-ridge moving trolleys 12, 12 are approximately matched in a series of relationships, the main rails in the opposing relationship again 5 and the auxiliary rail 6 are connected by a flexible pipe 10. After untying the connector 13, the tea garden management device 7 is manually pushed or pulled onto the main rails 5, 5, thereby achieving the purpose of relocation.

Regarding the ridge moving trolley 12, its platform 3
Two auxiliary rails 6, 6 are provided on the top in parallel at approximately the same interval as the main rails 5, 5 on both sides of the brown ridge 4,
Of course, it is also possible to implement the system using a single carriage. However, in this case, in order to cope with errors or changes in the spacing between the main rails 5, 5, it is desirable to add a spacing adjustment mechanism that moves one or both of the auxiliary rails 6 in parallel.

Effects of the present invention As described above in detail in conjunction with the embodiments, according to the ridge moving trolley 12 of the track-type tea garden management device according to this invention, the legs of the track-type tea garden management device 7 are rotated. No mechanism is required, and the leg can be made into a simple and rigid integral structure, making it easy and inexpensive to design and manufacture. Further, the legs (feet) of the tea garden management device 7 are structurally strong and highly rigid, making it safe to use.

Furthermore, since the relocation work of the tea garden management device 7 involves placing it on the ridge moving trolley 12 and moving it laterally, it is possible to proceed with the work slowly and reliably, even while taking a break or thinking during the relocation work. is possible,
Able to work safely.

Moreover, as long as the swivel casters 2 of the trolley 12 are within the travelable range, you can freely change the distance of relocation, select the relocation location, or change the relocation location midway, and it is easy to use, which ultimately contributes to improving the efficiency of tea plantation management work. That's what I do.
