Description

[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). Track-type tea garden management consists of legs equipped with wheels that run on tracks laid on both sides of the tea ridges, a pedestal mounted on the left and right legs, and management machinery such as a plucking machine installed on the pedestal. Regarding equipment, and more specifically,
Regarding the improvement of tea garden management equipment related to No. 48432.

Prior Art The tea plantation management device according to the above-mentioned Utility Model Application Publication No. 63-48432 is
As schematically shown in FIG. 4 of the drawings, a pedestal 5 is mounted on the left and right legs 4, 4 equipped with wheels 3 that run on tracks 2, 2 laid in the passages on both sides of the brown furrow (not shown). has been erected.

The planar shape of the pedestal 5 is a rectangular frame having substantially the same dimensions as the track width.

A horizontal frame 24 arranged in the track width direction of the frame 5,
Two support pipes 32, 32 are installed in a symmetrical arrangement between the two support pipes 32, 32, and a management machine 6, such as a plucking machine, is installed on the two support pipes 32, 32. The management machine 6 has left and right handle parts 6a, 6.
A is placed on the support pipes 32, 32.

This track-type tea garden management device installs the management machine 6 in the proper working posture and position for pruning and plucking the tea plants, and allows the worker who walks along the path between the tea furrows to push or pull the machine to run the management work. carried out by people. Then, the picked tea leaves are packed into bags in a certain amount and placed in a passageway, or a loading platform 36 is provided at the lower part of the legs 4, and the tea leaves are placed thereon and carried to the end of the tea ridge. Alternatively, although not shown, a separate cart may be run on the track 2, and bags of tea leaves may be loaded and transported.

Problems to be solved by the present invention () As with the conventional tea garden management device described above, when placing the bags of picked tea leaves in the path between the tea furrows, the path width is narrow, so they end up being placed on top of the tea plants. It is undeniable that it will hurt. Also, even when carrying the leaves on the carrier 36, the amount that can be loaded on this is limited, and it is not enough to carry the picked leaves from one end of the long brown furrow to the other, and in the end, the only thing to do is to put them down on the aisle. The reality is that there is not.

Furthermore, when a separate cart is run on the track 2, another worker is required to move the cart, which poses problems such as labor savings cannot be achieved.

() This track-type tea garden management device is moved by one worker by pushing or pulling it by hand to proceed with the management work, but the worker who has no choice but to walk along the path between the tea furrows basically puts the rear corner of the mount 5 on the track. Or you can only push or pull the front corner with one hand. For this reason, the frame 5
A diagonal force (torsion) is applied to the orbit 2 at a certain angle. Therefore, it is undeniable that the device frame is twisted and the initially set proper working position and posture of the control machine 6 are disturbed.

In addition, as mentioned above, the worker applies a twisting force at a certain angle to the direction of the track 2, so there is waste in pushing or pulling the tea garden management device.
It is a heavy burden (hard labor) for the workers. At the same time, there is a risk that the wheels 3 may come off the track 2, which is a problem.

Means for Solving the Problems As a means for solving the problems of the prior art described above, a preferred embodiment of the track-type tea garden management device according to this invention is shown in FIGS. 1 to 3 of the drawings. As shown, wheels 3 run on tracks 2 laid on both sides of the brown furrow.
A track-type tea garden management device comprising a leg section 4 with a base 4, a pedestal 5 mounted on the leg sections 4, 4, and a management machine 6 such as a plucking machine installed on the pedestal 5. A loading platform 8 for harvested products, etc. is removably attached via a frame 7. In addition, the planar shape of the handgrip 9a of the gantry 5 is shaped so that the force of pushing or pulling the manual handle 9 by the worker's hand is balanced on at least one side surface of the gantry 5 in the running direction.
The angle is about 100°, and the frame 5 is configured in a triangular shape with the aggregate in the track width direction as the hypotenuse.

Function This tea garden management device performs management work while traveling along track 2. Then, as soon as the tea leaves (fresh leaves) are picked by the picking machine 6 and packed into bags, the bags are placed on a carrier 8 and transported. The loading platform 8 can be made into the required size and shape by making wide use of the space on the stand 5 of the tea garden management device, so it can be used to store bagged tea leaves at least while picking from one end of a long tea ridge to the other. can be easily carried along with the tea garden management equipment for both traveling and work purposes.

When replacing or maintaining the management machine 6, the loading frame 8 can be removed by removing the frame 7 from the pedestal 5, so that it does not get in the way.

Next, in the tea garden management device, a worker who walks along the path between tea rows can push or pull the handle 9 with one hand to run on the track 2 and perform management work. The handle 9 has a shape that distributes the manual force pushed or pulled with one hand by a worker who has no choice but to walk along the path between the brown furrows, so that the distribution of manual force is well balanced over the entire pedestal 5, and the force is applied in the same direction as the track 2. Since the frame 5 is not twisted while running in the direction of the track 2, the proper working posture and position of the management machine 6 set at the beginning can be maintained. And there is no risk of the wheels falling off.

Embodiment Next, the embodiment shown in FIGS. 1 to 3 will be described.

First, in FIG. 1, reference numerals 2 and 2 are tracks laid parallel to the passage portions on both sides of the brown furrow (not shown). A frame 5 is installed on the left and right legs 4, 4 having wheels 3, 3 running on the tracks 2, 2. A management machine 6 such as a plucking machine is mounted on the support pipes 32, 32 of this mount 5 in the manner shown in FIG. (Omitted). Also,
A loading platform 8 is mounted on the pedestal 5 by using a frame 7 so as to be raised to a height that does not interfere with the working posture of the management machine 6 at all.

The skeletons of the illustrated legs 4, pedestal 5, loading platform 8, etc. 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 resin (trade name), and these are connected using joints made of the same material.

The leg section 4 is constructed as a rectangular flat frame assembly with a length of about 60 cm in the same direction as the track 2 and a height of 15 cm, and includes a running platform 1 with wheels 3, 3 attached to the lower corners of both front and rear ends. There is.

The leg portions 4 are integrally formed with the pedestal 5 and project vertically downward from the left and right ends of the pedestal 5, and are stiffened by two chin rests 31, 31.
As shown in FIG. 2, the planar shape of the frame 5 is assembled into a rectangular shape with a length extending over the adjacent tracks 2, 2.

The traveling platform 1 and the leg portion 4 are connected via a sufficiently long rotating shaft 7', and two clamps 10, 10
are strongly connected and integrated. Therefore,
The frame 5 does not wobble or shake unstablely during work or traveling.

The loading platform 8 shown in FIG. 1 has a rectangular planar shape that is approximately the same shape and size as the pedestal 5. Two frames 7, 7 projecting vertically downward with a length of about 15 cm are provided in parallel by T-shaped joints 11 and cross-shaped joints 12 provided above and below the center of both ends of the loading platform 8, Bolt-tight metal clamps 13, 13 are attached to the lower ends of the frames 7, 7. The frames 7, 7 of the loading platform 8 are removably attached to the frame 5 by the clamps 13, 13.

In other words, the loading platform 8 is removably mounted so as to be raised above the pedestal 5 by the length of the protruding frame 7. Therefore, there is no hindrance to the replacement or adjustment work of the management machine installed on the pedestal 5 or to the proper working posture and position of the management machine 6.

The peripheral frame portion of the loading platform 8 has a double pipe structure in which two resin-coated steel pipes are arranged vertically in parallel at an interval of approximately 15 cm. And, between the lower pipes 14, 14 in the longitudinal direction, several bottom pipes 15 are provided.
... are placed at just enough intervals to prevent the bags of tea leaves from falling out, forming a box-shaped structure.

Therefore, the tea leaves and other items picked by the picking machine and packed into bags can be loaded one after another onto the carrier 8 as if thrown into the bag.

Next, as shown separately in FIG. 2 for clarity of illustration, a manual drive is installed on the horizontal frame in the track width direction that forms the front (or rear) side surface of the gantry 5 in the running direction. A handle 9 is provided. The shape of this handle 9 is such that, as the planar shape is specifically shown in FIG. It is formed so that it is well balanced and acts equally as a force in the direction of orbit 2. That is,
The angle α of the grip portion 9a of the handle 9 is 100°, the intersecting angle β with the platform 5 on the worker side is 60°, and the intersecting angle γ on the opposite side is 20°.
It is formed into a triangular shape with the hypotenuse being substantially the entire length of the horizontal frame of the pedestal 5. The handle 9 is also made by bending a resin-coated steel pipe, and with the triangular shape in a horizontal position, both ends of the handle 9 are integrally connected to the horizontal pipe 24 of the frame 5 by joints 16 and 17. ing. A joint 18 is also used to maintain the horizontal position of the handle 9.

Therefore, a worker walking along the path between the tea furrows can simply grasp the grip portion 9a of the handle 9 and push or pull it. Then, this manual force is applied to the approximately triangular handle 9.
Appropriate force components are generated along the two sides forming the grip portion 9a, and a well-balanced force is applied to the pedestal 5 in the direction of the track 2, causing the tea plantation management device to move along the track 2. This allows the robot to run in a straight line and accomplish the desired management task.

Effects of the present invention As detailed above in conjunction with the embodiments, in the case of the track-type tea garden management device according to this invention,
Tea leaves or other items that are picked and packed in bags are
Since you can carry only the necessary and sufficient amount on the loading platform 8,
It is extremely convenient for carrying out administrative tasks.

That is, it is possible to avoid damaging the tea leaves by lowering the bag containing the picked tea leaves into the path between the tea ridges. Further, the transportation of various items can be easily carried out by the worker who operates the tea garden management device, so that labor savings can be achieved.

Moreover, this tea garden management device allows a worker walking along the path between the tea rows to carry out management work by grasping the handle 9 and pushing or pulling it. It does not disturb your working posture or position. Therefore, highly accurate management work is possible, contributing to the production of high-quality tea leaves. Furthermore, there is no risk of trouble such as the wheels 3 coming off the track 2.
