[Detailed description of the invention] Industrial application field This invention is a tea plantation management device used for picking tea leaves (fresh leaves), pruning tea plants (tea fields), and various other management tasks in tea plantations (tea plantations). A running platform with wheels that run on tracks laid on both sides of the brown furrow, legs to which it is attached, a pedestal mounted on the left and right legs, and management machinery such as a plucking machine installed on the pedestal. Regarding the structure of the legs and running platform of the track-type tea garden management device consisting of
This issue relates to the improvement of tea plantation management equipment according to No. 48432.

BACKGROUND ART The structure of the legs and traveling platform of the tea garden management device according to the above-mentioned Utility Model Application Publication No. 63-48432 is constructed as schematically shown in FIGS. 3 and 4 of the drawings.

That is, the leg portion 4 is integrally constructed with a traveling base 1 having one front and rear wheel 3 that travels on a track 2.

The traveling platform portion 1 is constructed of a pipe material as a rectangular flat frame body elongated in the same direction as the track 2, and wheels 3, 3 are attached to the lower corners of both front and rear ends thereof.

At the center of the traveling platform portion 1, a cross-shaped joint 15,
Two long columns 14, 14 are vertically erected by means of 15, and their upper ends are connected by a connecting frame 16, thereby constructing a very strong leg skeleton.

At the center of the upper edge of the connecting frame 16, a short rotating shaft 20 is fixed vertically upward by a cross-shaped joint 18 and a T-shaped joint 19. The rotating shaft 20
are inserted into and supported by a T-shaped joint 27 and a cross-shaped joint 28, which are bearings provided above and below the center of the side end of the pedestal 5, so that the legs 4 and the pedestal 5 are rotatably connected. has been done.

The pedestal 5 is constructed of a pipe material and has a rectangular planar shape. The leg portions 4 and the pedestal 5 are connected and reinforced by a chin rest 31. The chin rest 31 has a nearly C-shaped half socket 29a joint 29 at one end, and a metal clamp 3 at the other end.
0 (Fig. 4), and is bent in a shape to avoid interference with the brown ridges.The joint 29 at one end is attached to the lower horizontal pipe 24 in the frame 5, and the metal clamp 30 at the other end is Travel platform part 1 of leg part 4
It is connected to the upper frame pipe 17 that constitutes the upper frame pipe 17.

The reason why the legs 4 and the traveling platform 1 are configured as described above is that the track-type tea garden management device can complete the tea picking work of the tea furrow it is currently working on up to the end of the same furrow, and then pick the tea from the tea furrow it is currently straddling. This is to allow one person to perform this work when changing tracks to pick tea from the tea ridges. That is, the chin rest 31 that connects the leg portion 4 on the corresponding side and the pedestal 5
The joint 29 and the clamp 30 are removed, and the relationship between the leg portion 4 and the pedestal 5 is made rotatable. After that, the worker holds the opposite leg 4 and lifts the wheel 3 of the lever.
Lift it off the track 2, walk along the path between the tea furrows, go around the track on the opposite side of the adjacent tea furrow, and place the wheel 3 on the same track 2. Then, at this time, the pedestal 5 pivots around the rotation axis 20 of the leg portion 4 that is in a rotatable relationship, and the worker is allowed to move.

Thereafter, by reattaching the removed cheek rest 31 and connecting the legs 4 and the pedestal 5 as described above, the tea garden management apparatus becomes ready to work across the new tea ridge.

Problems to be Solved by the Present Invention () In the case of the structure of the legs and traveling platform of the conventional track-type tea garden management device described above, the pedestal 5 and the leg 4 are connected by one relatively short rotating shaft 20. Since the connected state is only reinforced by the two chin rests 31, 31, there is a lack of strong integrity between the legs 4 and the pedestal 5, which may cause problems during work or while traveling. There is an instability in which the pedestal 5 wobbles.

In particular, a 10-16 kg plucking machine and other management machines are installed on the pedestal 5, and the joint 29 of the cheek cane 31 is attached by simply fitting the C-shaped socket 29a into the pipe 24 of the pedestal 5 from the side. In addition, the C-shaped socket 29a has a rough installation structure that makes it easy to move in the longitudinal direction of the pipe 24, and this tea garden management device cannot be pushed by hand by a worker walking along the path between the tea ridges. Alternatively, in the case of a type in which the work is carried out by pulling, the push/pull force applied tends to be biased, making it difficult to use because the pedestal 5 wobbles and shakes during work or traveling, making it unstable and dangerous.

Moreover, when the pedestal 5 shakes, there are problems such as variations in work precision during management work such as pruning tea plants or plucking fresh leaves, and the shape of the tea plants becoming irregular.

() Furthermore, according to the structure of the legs and running platform of the conventional track-type tea garden management device described above, when the management work of one tea furrow is completed and the track is changed for the management work of the next tea furrow, , a total of four chin rests 31, two on each side, must be attached and detached each time. The work of attaching and detaching one chin rest 31 requires attaching and detaching the clamp 30 and the joint 29, respectively, and thus takes a lot of effort as a whole. Moreover, with regard to the attachment and detachment of the joint 29, if the C-shaped socket 29a is designed to be easily attached and detached, the coupling force will be insufficient and the instability described in () above will increase. On the other hand, if the structure has a sufficiently strong bonding force, there is a problem that attaching and detaching operations become extremely difficult.

Means for Solving the Problems As a means for solving the above-mentioned problems of the prior art, the structure of the legs and the traveling platform of the track-type tea garden management device according to this invention is shown in FIGS. 1 and 2 of the drawings. As shown in the preferred embodiment, wheels 3 run on tracks 2 laid on both sides of the brown furrow.
A traveling platform 1 equipped with a running platform 1, a leg portion 4 to which the traveling platform 1 is attached, and a pedestal 5 constructed on the left and right legs 4, 4.
In the track-type tea garden management device, which comprises a management machine such as a plucking machine installed on a pedestal 5, the traveling platform 1 has one vertical and sufficiently long rotating shaft 7 at the upper center thereof, and the The structure is such that clamps 6, 6 are provided on both sides of the shaft 7 and can be attached and detached in an upward posture.

Further, the leg portions 4 are provided to protrude downward from both ends of the pedestal 5, and are firmly reinforced with chin rests 31. Furthermore, the leg portion 4 is provided with bearings 8 and 9 that rotatably support the rotating shaft 7 of the traveling base 1 at the upper and lower sides.

The traveling platform 1 is configured such that the rotating shaft 7 is supported by bearings 8 and 9 of the leg portions 4, and is detachably connected to the connecting frame 10 of the leg portions 4 using clamps 6 and 6.

Operation When the tea garden management device is to be transferred to the track 2 as the management work progresses, the clamps 6, 6 on the relevant side are first released. Then, the traveling platform 1 and the leg section 4 are in a state where they can turn around the rotating shaft 7. Therefore, by lifting the leg 4 on the opposite side and walking along the passage, changing tracks 2 can be easily done by one person.

When the change of track 2 is completed, the clamp 6 is again connected to the connecting frame 10 of the leg part 4 and tightened and fixed. By doing this, the traveling platform 1, the leg portions 4, and the pedestal 5 are again firmly integrated into a rigid structure.

That is, the traveling platform 1 and the leg section 4 are connected in a state of high rigidity against bending or falling in a direction perpendicular to the track 2 by a long rotating shaft 7 that makes full use of the height dimension of the leg section 4. The legs 4 are integrated with the pedestal 5 and protrude downward, and the pedestal 5 and the legs 4 are firmly connected with a chin rest 31. This is because it is stiffened.

Embodiment Next, the embodiment shown in FIGS. 1 and 2 will be described.

First, in FIG. 1, 2, 2 are tracks laid parallel to the passages on both sides of the brown furrow (not shown), and 1, 1 are equipped with wheels 3, 3 that run on the tracks 2, 2. It is a traveling platform. Reference numeral 5 in the figure denotes a pedestal mounted on the traveling platforms 1, 1 via leg portions 4, 4. A management machine such as a plucking machine (not shown) is mounted on this pedestal 5.

The skeletons of the illustrated running platform 1, legs 4, and pedestal 5 are made of thin-walled steel pipes with good weather resistance.
Resin-coated steel pipes with an outer diameter of approximately φ28 are used as aggregates and are thinly and uniformly coated with synthetic resin such as AAS, and are assembled by connecting them with joints made of the same material.

The length of the traveling platform 1 in the same direction as the track 2 is approximately 60 cm.
It is constructed as a rectangular flat frame assembly with a height of about 15 cm, and wheels 3, 3 are attached to the lower corners of both the front and rear ends. In addition, a cross-shaped joint 15 is used at the center of the upper frame of the traveling platform 1, and one long rotation shaft 7 is provided vertically upward passing through the cross-shaped joint 15 (the second
figure). The length (height) of the rotating shaft 7 is approximately the length of the leg 4.
It is said to be close to the height of (approximately 60 cm).

Further, cross-shaped joints 15, 15 are similarly used at both ends of the cross-shaped joint 15 in the center of the upper frame, and metal orthogonal type flexible clamps 6, 6 are attached to the upper end of the pipe 11 that is passed through the cross-shaped joints 15, 15. It is placed in an upward facing position.

The legs 4 are integrally formed with the pedestal 5 and protrude vertically downward from both ends of the pedestal 5,
It is reinforced with two chin rests 31, 31. Frame 5
The planar shape of is assembled into a rectangular shape with a length spanning between the adjacent tracks 2, 2.

The legs 4 are attached to the upper and lower frame members at both ends of the pedestal 5.
Long side columns 14, 14 are provided vertically downward through the type joint 27 and cross type joint 28.
The lower end of the connector is rigidly connected with a connecting frame 10 to form a substantially rectangular shape (FIG. 2). The side column 14 and the lateral pipe 24 of the pedestal 5 are rigidly connected by a chin rest 31, so that the leg portion 4 is stiffened. The chin rest 31 has bolted metal joints 12, 12 at both ends thereof, and is strongly and rigidly connected to the side column 14 and the pipe 24 by the joints 12. Therefore, there is no fear that the connecting portion of the joint 12 will slip, and the leg portion 4 has extremely high rigidity against external force (falling or bending), especially in a direction perpendicular to the track 2.

A cross-shaped joint 9 is used for bearing at the center of the connecting frame 10 at the lower end of the leg portion 4. Further, a T-shaped joint 8 for bearing is also used for the auxiliary frame 13 provided above the leg portion 4 in parallel with the connecting frame 10, and these cross-shaped joints 9 and T-shaped joint 8 are connected to the traveling base. The distal end and proximal end thereof are rotatably supported through a long rotating shaft 7.

In this way, the traveling platform 1 and the leg section 4 are connected and supported via the rotating shaft 7, which is long enough to span the entire height of the leg section 4, so that external forces (falling or bending) in a direction perpendicular to the track 2 are particularly avoided. It has great rigidity. On top of that,
The traveling base 1 and the legs 4, 4 are connected to two clamps 6,
Since the pedestals 6 are firmly connected and integrated, the pedestal 5 will not wobble or swing unstably during work or travel, allowing highly stable management work.

When changing the track 2, it can be started immediately by releasing the two clamps 6, 6 on the relevant side, and it can be completed by simply tightening the two clamps 6, 6 again after changing, so it is extremely convenient. It can be operated easily and safely.

Effects of the present invention As described above in detail in conjunction with the embodiments, according to the structure of the legs and the running base of the track-type tea garden management device according to this invention, the legs 4 and the running base 1
has a strong integrated structure with a long rotating shaft 7 and a detachable clamp 6, and the stiffening effect of the chin rest 31 is sufficiently effective, so the frame of the entire device is strong and rigid. Therefore, there is no instability or danger caused by the pedestal 5 wobbling during work or traveling, and maintenance work such as pruning tea tree branches or plucking fresh leaves can be performed accurately, precisely, and with good stability.

In addition, the legs 4 and the traveling base 1 are assembled by supporting the rotary shaft 7 through bearings 8 and 9, and by supporting the rotating shaft 7 with the clamp 6.
The work can be done quickly and efficiently by simply tightening it.

Furthermore, when changing trajectory 2, simply 2
It is easy and quick to attach and detach the clamps 6 and 6, and the work efficiency is high.
