DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Object of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for handling a rail-traveling tea garden management cart that runs across a tea ridge in a tea garden and manages plucking, pruning, fertilizing, and the like of tea leaves. In particular, even under all tea plantation conditions where the tea plantation terrain, ridge width, etc. are different, the rail-traveling tea plantation management cart can be smoothly transferred onto the tea plantation rails or moved between tea ridges. It relates to the management trolley.

[0002]

BACKGROUND OF THE INVENTION In order to save labor in tea garden management, rail-traveling tea garden management carts have been widely used in which rails are laid between tea ridges and run on the rails so as to straddle the tea ridges. Such a rail-running tea garden management cart has a very effective labor-saving effect as long as it travels on a tea ridge and performs a predetermined work. A great deal of labor is required to move the rail-running tea garden management trolley to the rail between the tea ridges at the time of moving the ridge or at the start or end of the work. For this reason, a hand-held traveling type gantry is conventionally used, and a support rail capable of connecting the rail end of the tea garden as if it is extended is almost fixedly mounted on the gantry, and the support rail of the gantry is mounted at the rail end of the tea garden. A rail-running tea garden management cart is mounted on the side so that it can be received and moved to a predetermined position.

[0003] However, in the conventional gantry, no special measures have been taken to provide the bearing rails, so that it is a tea plantation on a flat ground, and the angle between the tea ridge and the so-called headland at the end thereof is almost equal. It can only be used in a very ideal tea garden set at right angles.
Looking at the actual tea garden form, there are few such ideal tea gardens, and the tea ridge surface is inclined in the direction of the tea ridge or the direction of the arrangement of the tea ridges, or the headland and the tea ridge cross diagonally. Further, while the tea ridges are inclined, the headlands are leveled horizontally as viewed in the direction of the tea ridges, and the forms thereof vary widely.

[0004] For this reason, in the conventional type in which the bearing rail is simply attached to the hand-held traveling stand, the tea garden that can use this is extremely limited, and it cannot be used by many tea farmers. Regardless of the type of tea garden, there has been a demand for a mobile gantry that can be used more generally. Of course, even if the tea garden form is not the ideal form as described above, if the form is fixed, it can be dealt with if the gantry device is specially designed according to it,
In such a case, it cannot be used for other forms of tea garden at all,
It is not possible to cope with a case where a single tea farmer has a tea garden of a different form in several places, or a case where the farmer tries to share a gantry device when the tea garden form is different.

[0005]

[Technical Issues Attempted to Be Developed] The present invention has been made in view of such a background, and even in a tea garden of all conditions and forms, a rail-running tea garden management cart smoothly moves to a rail of a tea garden. The present invention has attempted to develop a new rail mount type traveling equipment for a tea garden management trolley, which can be removed and easily replaced after one tea ridge operation is completed.

[0006]

Configuration of the Invention

Means for Achieving the Object A first invention of a rail-mounted tea garden management cart moving gantry according to the present application comprises a traveling body having a traveling body and a loading frame for directly mounting the rail-traveled tea garden management cart.

In this case, the user can select a posture in a three-dimensional direction including turning and lifting.

[0007] The second invention of the moving gantry device for a rail-running tea garden management cart according to the present invention is based on the above-mentioned requirements.
In selecting the posture in the three-dimensional direction including turning and raising / lowering of the two bearing rails with respect to the ground, the loading gantry is characterized by changing its posture relative to the traveling body. Things.

[0008] Furthermore, in the third invention of the moving stand device for the rail traveling type tea garden management cart according to the present application, in addition to the above requirements, a rail stay in the tea garden is gripped by the telescopic side end of the support rail. A gripping device is provided.

Further, a fourth invention of a moving gantry for a rail-running tea garden management cart according to the present application is characterized in that, in addition to the above requirements, the running body is driven by a prime mover.

[0010] Furthermore, a fifth invention of a moving gantry apparatus for a rail-running tea garden management cart according to the present application is characterized in that, in addition to the above requirements, the traveling body is a crawler. The present invention aims to achieve the above object.

[0011]

According to the present invention, the traveling machine having the traveling body is moved to a position near the place where the rail traveling type tea garden management cart is transferred. When the rail-traveling-type tea garden management cart is loaded on the moving frame device, the wheel-mounted tea garden management cart is supported with wheels mounted on bearing rails in the transfer frame. Therefore, when mounting on the moving platform from the rail between the tea ridges, or conversely, when changing from the moving platform to the rail of the tea garden, first move to the nearest distance of the site and then rotate the loading platform appropriately. The posture is selected in a three-dimensional direction including lifting and lowering, and the two supporting rails provided in parallel are matched so as to be connected substantially linearly to the tea ridge rails. In this way, the rail-traveling tea garden management cart can freely move between the rails of the tea garden and the support rails of the moving gantry device, and can be transferred to the tea garden or removed from the tea garden.

The moving gantry A of the present invention has the specific structure as described above, and operates as follows to move the rail-traveling tea garden management cart 5. i) Storage in a warehouse or the like First, when the rail-traveling tea garden management cart 5 is stored in a warehouse such as a farmhouse, it may be dropped from the moving gantry A and stored. If there is no use, it may be stored in a state mounted on this device. This mounting state is the condition of the wheels 51 in the rail traveling tea garden management cart 5.
Is stored in such a state that it is mounted on a support rail 23 provided on the loading frame 2 of the moving frame device A.

Ii) Loading on Trucks, etc. Then, when moving from the storage location to an appropriate tea garden 6, when the tea garden is far from the tea garden, and once loading on the truck 7, etc. As shown in FIG. 6, in a state where the ladder rail 71 is obliquely bridged over the loading platform such as the truck 7 or the like, the prime mover 12 of the moving platform apparatus A is started, thereby driving the crawler 11 as a traveling body. Is loaded on the loading platform of the truck 7.

Iii) Transfer to the tea garden rail This work is performed from the headland 62 in the tea garden 6 or the farm road corresponding to the headland adjacent to the tea garden 6, and the rail traveling tea garden management cart 5 is mounted. After being lowered from the truck, the moving gantry A is driven by the crawler 11 as a running body to move near the predetermined ridge 61 on the headland 62. Of course, when the traveling body is not driven, the traveling body is appropriately moved by a manual pushing operation or the like. In such a state, the moving gantry device A approaches the end of the tea ridge 61.
Sets the posture of the loading gantry 2 in accordance with the state of the tea ridge. At this time, since the tea ridge 61 and the headland 62 intersect at a right angle or at a fixed angle, the attitude relationship between the loading gantry 2 and the traveling machine body 1 in the plane direction is determined by the support rails 23 of the loading gantry 2. Is set so as to intersect the traveling direction of the crawler 11 in the traveling body 1 at a right angle or at a certain angle.

For example, as shown in FIG. 7, the tea ridge 61 is inclined at a constant angle, while a headland 62 at the end thereof is provided.
When the ground is leveled substantially horizontally, one or both of the pair of support cylinders 22 and, if necessary, the inclined cylinder 24 are also expanded and contracted to set the set angle of the rail supporting machine frame 21 with respect to the traveling machine body 1. Then, the posture is selected so that the bearing rail 23 is finally connected substantially linearly to the rail 63 in the tea garden 6. At this time, of course,
In addition to the inclination setting, the extension 23b is appropriately extended so that the end of the extension 23b of the support rail 23 reaches the rail 63 in the tea garden 6, and a setting is made such that both are connected.

In this case, as shown in FIG. 8, when the headland 62 and the tea ridge 61 do not intersect at a right angle, the support rails 23 are made to have different extending dimensions, so that The connection with the rail 63 is achieved.
In order to reliably maintain this state, the pair of grip pieces 33a of the gripping device 33 are
It is in a state where it grips the 3rd rail stay 63A,
Maintain the connection state. After such a connection is made, the rail traveling tea garden management cart 5 is driven to run and travels, and when the extending portion 23b is extended from the main body portion 23a of the support rail 23, it is moved thereon. And the rail 6 in the tea garden 6 beyond the connecting piece 23c.
It is transferred to No.3. In such a state, the vehicle travels over the tea ridge 61, and the rail-traveling tea garden management cart 5 performs a certain operation, for example, a tea leaf picking operation, returns to the starting point, and moves to the next tea ridge 61. .

Iv) Movement between furrows When the rail-traveling tea garden management cart 5 moves between the furrows 61 after returning to the starting point as described above, the moving gantry A for moving between the furrows 61 is The transported state is kept as it is, and the rail-traveling tea garden management cart 5 that has returned there while waiting is transferred to the support rail 23 so as to be received as it is. After the rail traveling type control cart 5 is transferred in this manner, the gripping device 33 and the connection piece 23 on the support rail 23 are used.
c is released, and the connection state with the rail 63 on the tea garden 6 side is released. Thereafter, the crawler 11 of the traveling machine 1 is driven and moved by one tea ridge, and in this situation, the rail traveling tea garden management cart 5 moves sideways. Also in this case, the posture of the loading gantry 2 is selected as in the previous case, and the posture is set corresponding to the pair of rails 63 to be transferred. Then, similarly to the case described above, the connection between the support rail 23 in the moving gantry A and the rail 63 in the tea garden 6 is made, and the rail traveling type tea garden management cart 5 is moved to the tea ridge 61 side by self-propelled. Hereinafter, this operation is repeated.

[0034]

[Other Embodiments] The present invention has the basic embodiment as described above.
Should be configured so that at least all the positions of the loading gantry 2 can be set so as to match the rails 63 in the tea garden 6 with reference to, for example, a method as shown in FIG. . That is, when connecting the loading gantry 2 to the traveling body 1, the loading gantry 2 is supported so that the loading gantry 2 can be tilted in the three-dimensional direction at the center pivot 100, and the center pivot 100 itself is connected to the rod 101 A of the lifting cylinder 101.
The top of the rod 101A is set so that it can rotate in the vertical direction and the turning direction.
And at least two tilt setting cylinders 103 are provided from the subframe 102 provided integrally with the mounting frame 2 (in this case, the two tilt setting cylinders 103 and the center pivot 100 are arranged so as not to be aligned). Can be tilted in any direction.
