Description

[Detailed explanation of the invention] Industrial application field This invention is used in the field of tea cultivation agriculture, where many long tea ridges are planted in a large tea field and tea leaves (fresh leaves) are produced on a large scale. This invention relates to a track-type tea garden management device that is used for various purposes such as trimming, pruning, fertilizing, and spraying pesticides.

Conventional technology Conventionally, a track type with a lightweight structure was constructed in which a track was laid on both sides of a tea ridge, and a frame was built on both legs equipped with wheels that ran on the track to straddle the tea tree. The tea garden management device is already known and has been described in Japanese Utility Model Application Publication No. 63-101033 and Japanese Utility Model Application Publication No. 63-48432. Known track-type tea garden management devices include a transport vehicle that mounts a tea cutter on its stand to pick tea leaves, or places harvested fresh leaves in bags or fertilizer bags for fertilization on the stand. It is used for multi-purpose tea garden management, and it has relieved the heavy labor of tea garden management, reduced labor costs, and improved the quality of work.

Problems to be Solved by the Present Invention The spacing between the tracks attached to both sides of the tea furrow is nothing but the result of laying tracks in the existing tea furrow passage without any consideration for the use of the track-type tea garden management device.
The spacing between existing tea ridges depends on the topographical conditions of the tea plantation.
They vary in size from 160cm to 190cm.

Therefore, the track-type tea garden management device must be able to run on tracks on both sides of the tea ridges, which are located at different intervals even though they belong to the same tea field. In addition, the parallelism of the tracks on both sides of the brown ridge varies due to the rough construction work, so it is not possible to travel on the tracks while sufficiently dealing with such deviations in parallelism (parallel spacing). becomes impractical. However, conventional track-type tea garden management devices do not have the flexibility and flexibility to deal with the above-mentioned differences in track spacing, and their applicability is small and limited, which is a serious drawback. ing.

Conventionally, as a solution to the above-mentioned drawbacks, the width of the frame may be changed depending on the application conditions, but in practice this is extremely troublesome and costly, so it has not been possible to solve the problem.

Also, in Figure 5B of Utility Model Application Publication No. 63-48432,
A tea plantation management device is described in which a wide wheel capable of absorbing a difference in the size of the interval caused by the irregularity of the parallelism of the track is adopted on one leg. However, the difference in track spacing that can be accommodated by this wide wheel is at most
It is only about 10cm to 15cm, which is not enough to absorb the above-mentioned difference in the size of the existing tea ridge spacing (about 30cm), and the scope of application of tea garden management equipment is still narrow, so this is an issue that needs to be solved. ing.

Means for Solving the Problems As a means for solving the problems of the above-mentioned prior art, the track-type tea garden management device according to this invention has tracks laid on both sides of the tea furrow 1, as shown in the embodiment in the drawings. In a tea plantation management device comprising legs 4, 4' on both sides equipped with wheels 3 running on the legs 2, 2, and a pedestal 5 installed on the legs 4, 4' on both sides, The leg portion 4' is firmly and rigidly connected to the pedestal 5, and the leg portion 4 on the other side and the pedestal 5 are swingably connected by a hinge mechanism 6 having a rotation axis in a direction parallel to the track 2. 5 is characterized by being provided with a regulating frame 7 that surrounds the swingable leg portion 4 and limits the maximum swing angle (FIGS. 1 and 2).

The present invention also provides legs 4, 4' on both sides with wheels 3 running on tracks 2, 2 laid on both sides of the brown furrow 1, and legs 4, 4' on both sides. In the tea garden management device, the leg 4' on one side is firmly connected to the pedestal 5, and the leg 4 and the pedestal 5 on the other side have a rotation axis parallel to the track 2. The base 5 is provided with a regulating frame 7 that surrounds the swingable legs 4 and limits the maximum swing angle. A tea leaf turning bar 8 having a shape that lightly contacts the surface layer of the tea plant 1 is attached from the bottom surface of the pedestal 5 to the inside of the legs 4, 4' on both sides.
A spray nozzle pulp 9 for dispersing pesticides, etc. is attached to a position immediately behind the tea plant in the direction of movement, and the outer surfaces of the pedestal 5 and both legs 4, 4' are covered with a scattering prevention cover 10 shaped so as not to interfere with the tea plant. Characteristics (Figures 3 and 4).

Operation: The swingable leg portion 4 freely responds to changes in the distance between the tracks 2, 2 by changing its swing angle. The maximum tilted state of the leg portion 4 is restricted by the regulating frame 7. When the inclination of the swingable legs 4 is approximately moderate (almost vertical), a certain form is stabilized due to the rigidity of the legs 4' that are rigidly connected to the other frame 5. is maintained. In other words, the distances from the track 2 on the swingable leg 4 side to the hinge mechanism 6 and from the track 2 on the rigidly connected leg 4' side to the hinge mechanism 6 are the distances between the tracks 2 and 2.
This is because the distance between the legs 4' remains constant regardless of the magnitude of the change, and the position of the hinge mechanism 6 remains constant with respect to the track 2 of the leg 4'.

In addition, during tea leaf control work, the tea leaf turning bar 8 located at the front of the management device in the direction of movement
Lightly touch the surface layer of the tea leaves and turn them over as the management device advances. Since the pesticide sprayed from the spray nozzle pipe 9 is sprayed there, the chemical solution is evenly and efficiently sprayed on the front and back surfaces of the tea leaves, resulting in effective pest control.

Embodiment Figures 1 and 2 show an embodiment of a track-type tea garden management device used for multiple purposes. It is constructed in the form of a gate to straddle the tea plant 1, with legs 4, 4' on both sides having wheels 3 running thereon, and a pedestal 5 built over the legs 4, 4' on both sides. The track 2, legs 4, 4', and pedestal 5 in the illustrated example are each manufactured by coating the outer periphery of a thin-walled steel pipe with a thin, uniform layer of AAS resin, etc., which has excellent weather resistance, and has an outer diameter of approximately φ28 to φ32. It uses resin-coated metal tubes to create a lightweight structure that is weatherproof and resistant to chemicals. However, the material and structure of the aggregate used are not limited to this example.

The leg portion 4' on one side is stiffened into a planar frame shape with several horizontal bars 11, and its upper end is connected to the joints 12, 12.
It is firmly and integrally connected to the pedestal 5 by the cradle 5, and a chin rest 13 is further incorporated to achieve a strong rigid connection.

The leg 4 on the other side is also stiffened into a planar frame shape with several horizontal bars 11, but both ends of the horizontal bars 11' at the upper end are connected to the sockets of the orthogonal joint 6 of the frame 5. A hinge mechanism is configured that is rotatably connected and has a rotation axis in a direction parallel to the track 2.
This leg portion 4 is capable of swinging around the horizontal beam 11'. The pedestal 5 includes the swingable legs 4.
A regulating frame 7 that surrounds the leg portion 4 and limits the maximum swing angle of the leg portion 4 is provided. The regulation frame 7 is used to control the legs when the distance between the tracks 2, 2 laid on the passages on both sides of the brown furrow 1 is, for example, in the range of 160 cm to 190 cm, and there is a difference in size of about 30 cm, as shown in Fig. 2. It is said that the size can be handled by changing the swing angle of 4.
The regulating frame 7 is strongly stiffened by a chin rest 14 installed between it and the pedestal 5.

Therefore, as shown in Figure 2, this tea garden management device has a gap between the track 2 on the left side and the track 2 on the right side of the figure, which is at the standard specification position P point or about 5 cm on both sides of point P. When the leg 4' on the right side in the figure and the pedestal 5 are rigidly connected, the swingable leg on the left side The section 4 also maintains sufficient stability for use while standing almost vertically, and can be used as is for various management tasks without leaning against the regulating frame 7. Therefore, even if there is a change in the degree of parallelism between the tracks 2, 2 within the range of the above-mentioned track spacing, various management operations can be performed without any problem.

Also, when the track 2 on the left side of Fig. 2 is at a position Q or R that is deviated by about 15 cm to the left or right from the standard specification position P mentioned above (therefore, the distance between QR and The difference in the orbital spacing is 30cm.
However, this management device maintains stability in its form with the swingable legs 4 tilting outward or inward and leaning against the inner and outer regulation frames 7, respectively, and can be used for various management tasks. . In other words, the track 2 was laid on both sides along the path of the existing tea furrow 1, which was planted without any consideration for the use of the track-type tea garden management device, and there was a difference in size of about 30 cm between the tracks. Even in such cases, this tea garden management system is flexible and flexible enough to be applied without any problems.

Second Embodiment Most of the configuration of the tea plantation management apparatus shown in FIGS. 3 and 4 is the same as that of the first embodiment described above. The feature of this embodiment is that from the bottom surface of the pedestal 5, the legs 4 on both sides,
4', a tea leaf turning bar 8 having a curved shape (see Fig. 4) that is approximately similar to the cross-sectional outline of the tea plant 1 and lightly contacts the surface layer of the tea plant 1 at a depth equivalent to one tea leaf. is attached.
This tea leaf turning bar 8 is supported by a joint 15 on the pedestal 5 so that its height can be adjusted in the vertical direction, and is attached to a pair of supports 16 that protrude downward.
It is removably attached. This is to remove it if it gets in the way when used for management work other than pest control work.

Further, at a position immediately behind the tea leaf turning bar 8 in the direction of movement of the management device, a pest control agent or the like having a curved shape that is approximately similar to the outline of the tea plant 1 and of a size that does not come into contact with the tea plant 1 is placed. Spraying nozzle pipe 9
It is attached. The spray nozzle pipe 9 is also detachably installed in a manner that it is held by a joint 17 of the pedestal 5, a joint 19 of the leg portion 4', and a joint 19 of the regulating frame 7 (FIG. 3). A flexible hose 18 is connected to one end of the spray nozzle pipe 9 to supply a pest control agent from a sprayer (not shown).

Furthermore, the outer surfaces of the pedestal 5 and both legs 4, 4' are covered with a scattering prevention cover 10 made of a vinyl sheet or the like. Therefore, wasteful and harmful scattering of pesticides and the like floating in the air in an aerosol state is prevented. Shatterproof cover 1
The front and rear surfaces of the tea tree 1 are cut out to be slightly larger than the outline of the tea tree 1 so as not to interfere with the tea tree 1.

Therefore, according to the tea garden management device of this embodiment, the work of spraying chemicals, etc. for the prevention of tea leaves can be carried out efficiently on the front and back surfaces of the tea leaves, and even on days when the wind blows considerably, there is almost no waste. And it can be done efficiently and in sanitary conditions for the workers.

Effects of the present invention As described above in detail in conjunction with the embodiments, the track-type tea garden management device according to the present invention is such that the distance between the tracks 2, 2 on both sides of the tea furrow 1 to which this device is applied is large or small to a certain extent. Even if there are differences in the parallelism of the tracks 2, 2, etc., it can be used without any problems and has excellent flexibility and flexibility in its application range.
It is extremely practical and economical.

In addition, the orbital tea garden management device according to this invention is
The spraying of chemicals for controlling the tea plant 1 can be sprayed all over the front and back surfaces of the tea leaves, and can be done hygienically with almost no waste even on days when there is a slight wind, so it is very practical.
