Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile working apparatus which can be used for various agricultural works such as tilling, rice planting, weeding, and harvesting in agriculture, or various works in forestry, livestock farming, etc. is there.

[0002]

2. Description of the Related Art In conventional agricultural work, tilling, weeding, harvesting, etc. are carried out by a tractor, and rice planting is carried out by a rice planting machine. For this reason, agricultural machinery was introduced for farming,
It can be said that farm work has become much easier compared to the days when people used to plow with mulberries, enter rice fields to manually plant rice, and mow rice with a sickle. In addition, seed sowing, fertilizer application, pesticide spraying, etc. in a vast field are made efficient by using an airplane.

[0003]

However, in the above-mentioned conventional agricultural machines such as tractors and rice transplanters, wheels or endless track zones are grounded on the field and rotatably driven to obtain traction force. Machines perform various tasks while moving in the fields. For this reason, depending on the conditions, such as whether the fields are dry or mud, grasslands, crops are planted, or whether or not seeds are sown, the fields are inclined. It is easily affected by moving the agricultural machinery depending on the terrain such as whether it is horizontal or horizontal. Therefore, it is necessary to devise a device corresponding to each condition, which not only complicates the model of the agricultural machine but also the structure thereof, which increases the cost of the agricultural machine and lowers the work efficiency.

Especially when a heavy agricultural machine passes through, the wheels and the endless track must pass through the area where the crops and seeds are sown. It is unavoidable that planting and seeding cannot be done and the planting efficiency is reduced. In addition, since a heavy agricultural machine passes through, fertile fields gradually become thin, making it difficult to grow agricultural products.

There is also a small agricultural machine used for working while walking while the worker carries it on his back, but not only increases the burden on the worker and the risk of falling, but is also easily affected by the weather and the like. There is a problem. In addition, if you use an airplane to sow seeds, there is a risk of hitting power lines and towers, and if the course deviates a little or the wind blows, it will not be evenly spread over the fields, and you will also find a residential area nearby. If there is, there is a problem that there is a risk that agricultural chemicals will be sprayed to the residential area.

[0006] Further, in the work in a markedly mud-swampy area such as a lotus field, conventionally, an operator carries his / her work machine to the chest or loads the work machine on a ship or a device combining a ship and an endless track. However, in each case, there is a problem that it is extremely inefficient and dangerous. Therefore, it is an object of the present invention to provide a mobile work apparatus that is not affected by various conditions such as the conditions of fields and topography, has a uniform structure, is low in cost, and prevents a decrease in work efficiency. .

[0007]

In order to solve the above-mentioned problems, the present invention is directed to a pair of track members arranged in the vicinity of both sides of a work area and a pair of track members facing each other in the lengthwise direction. A pair of first movement supporting means that moves while holding the position, and a pair of first movement supporting means arranged so as to extend in a direction perpendicular to the length direction of the track member, and both ends thereof supported by the pair of first movement supporting means. A long support member that moves integrally with the first moving and supporting means along the length direction of the track member; and a long support member that is supported by the long support member and moves along the length direction of the long support member. Two moving support means and a working means which is supported by the second moving support means and is movable integrally with the second moving support means and whose height position can be changed are provided.

[0008]

When the pair of first moving support means move along the lengthwise direction of each of the pair of track members arranged near both sides of the work area while holding the positions facing each other, A long support member, which is arranged so as to extend in a direction perpendicular to the length direction and whose both ends are supported by the first movement support means, moves integrally with the first movement support means. At this time, the second moving support means supported by the elongated support member moves along the length direction of the elongated support member. Therefore, the working means supported by the second movement supporting means can move to any position in the working area. Further, even if the work area has irregularities, the working means can change the height position thereof, and therefore can move along the irregularities.

As described above, the working means is supported by the second moving supporting means, the second moving supporting means is supported by the long supporting member and moves along the same, and the long supporting member is a pair of first moving supporting means. Since the pair of first movement supporting means is configured to move along the pair of track members, the working means is indirectly supported by the track members on both sides of the work area, and the working means is conventionally used. It becomes unnecessary to be supported by a tractor or the like moving in the work area as described above. Therefore, the mobile work device according to the present invention is not affected by various conditions such as the conditions of the fields and the topography. In addition, various work can be performed by changing the work means of the mobile work device according to the work purpose. Therefore, the basic structure is uniform and the cost is low, and the work efficiency is not affected by various conditions such as fields. Can be improved.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of a mobile work device according to the present invention. 1 and 2,
Reference numeral 13 is a work area (work area) such as a rice field or a field, and the width between both sides of the work area 13 is about 100 m. Reference numerals 10 and 11 are rails (track members), and the pair of rails 10 and 11 are arranged near both sides of the work site 13. A pair of first self-propelled devices 15 and 16 (first moving support means) are provided on the rails 10 and 11 respectively.
Are provided so as to be movable along their respective length directions.
The first self-propelled devices 15 and 16 are configured to move while holding the positions of the rails 10 and 11 facing each other in the lengthwise direction.

Reference numeral 18 is a truss (long support member) extending over both sides of the work site 13.
Are arranged so as to extend in a direction perpendicular to the length direction of the rails 10, 11. Since both ends of the truss 18 are supported by the pair of first self-propelled devices 15 and 16, the truss 18 is integrated with the first self-propelled devices 15 and 16 so as to be integrated with the rail 1.
It moves along the length direction of 0 and 11 (in the direction of arrow A in FIG. 1). As shown in FIG. 2, a pair of columnar members 17 are provided upright on both ends of the truss 18, and a tension wire 19 is stretched between the pair of columnar members 17 and 17. Since several points along the tension line 19 are connected to the truss 18 by suspension lines 21, the truss 1
8 is reinforced so that it does not hang down at the center.

The truss 18 is provided with a second self-propelled device 20. The second self-propelled device 20 moves along the length direction of the truss 18 (in the direction of arrow B in FIG. 1). ing. As shown in FIG. 2, various working machines 23 (working means) such as a cultivator, a rice transplanter, a weeder, and a reaper are replaceably attached to the lower end of the second self-propelled device 20. By the vertical movement of the movable member 20a of the traveling device 20, the working machine 23 can be vertically moved in the vertical direction (direction of arrow C in FIG. 2) to change its height position. Movement and movable member 20 of the first self-propelled devices 15 and 16 and the second self-propelled device 20.
The vertical movement of a is operated by an electric motor (not shown) driven by energization from a power source (not shown) via a wire (not shown).

The mobile work device according to the above embodiment is
A pair of first rails along the length direction of the pair of rails 10 and 11.
When the self-propelled devices 15 and 16 move while holding the positions opposed to each other, the truss 18 maintains the posture in the direction perpendicular to the length direction of the rails 10 and 11, and the first self-propelled devices 15 and 16 are maintained. Move together with. As the second self-propelled device 20 moves along the longitudinal direction of the truss 18 while the truss 18 moves, the second self-propelled device 20
Can be moved to any position on the work site 13.

The work machine 23 supported by the second self-propelled device 20 can also move to any position on the work site 13. Thus, the working machine 23 is the second self-propelled device 2
0, the second self-propelled device 20 is supported by the truss 18 and moves along the truss 18, and the truss 18 is supported by the pair of first self-propelled devices 15 and 16.
Since the working machines 5 and 16 are configured to move along the pair of rails 10 and 11, the working machine 23 indirectly operates the rail 1.
It is not necessary that the work implement 23 is supported by 0, 11 and is supported by a tractor or the like that moves in the work area 13 as in the conventional case.

Therefore, in the mobile work apparatus according to the present invention, whether the work area 13 is a dry land, a mud wetland, a grassland, a crop is planted, seeds are sown, or the like. Not affected by the situation.
Further, there is no influence on the movement of the work implement 23 due to the terrain such as whether the work place 13 is inclined or horizontal. Further, even if the work site 13 has irregularities, the working machine 23 can change its height position and therefore can move along the irregularities.
After all it is not affected. In addition, various kinds of work can be performed by converting the working machine 23 according to the work purpose such as tilling, weeding, and harvesting, so that the basic structure is uniform and the cost is lower than buying many types of agricultural machines. In addition, the work efficiency can be improved because it is not affected by various conditions of the work site 13 as described above.

In the above embodiment, the movable member 20a of the second self-propelled device 20 moves the working machine 23 up and down to change its height position. However, the working machine 23 extends vertically. It is also possible to provide a mechanism capable of rotating around the axis and arbitrarily setting the direction of the axis of rotation, and an optimum function can be added and selected according to the purpose of the working machine 23.

In the above embodiment, the case where the width of the work site 13 is about 100 m has been described, but it goes without saying that the width of the work site 13 may be smaller or larger than that. The length is also not particularly limited.
Moreover, it is not necessary to limit to each work in agriculture, it can be applied to each work in forestry, livestock, etc., and in any field such as greening deserts such as Africa, the Middle East, Central and South America, etc. The present invention can be applied to such uses.

Furthermore, the present invention can be applied not only to outdoor work but also to indoor work such as greenhouses and greenhouses, underground work, or underwater work. It can also be applied to applications.

[0019]

As described above, according to the present invention, the structure is uniform, the cost is low, and the work efficiency is prevented from being deteriorated without being influenced by various conditions such as the condition of the working area such as the fields and the topography. It is possible to provide the mobile work device. In addition, since the working means can be moved without using wheels or endless tracks as in the past, it is not necessary to secure a space for the wheels or endless tracks to pass in the work area, and the production area is increased accordingly. The efficiency can be increased. Further, since it is not necessary for a heavy agricultural machine to pass through, it is possible to prevent the heavy agricultural machine from stepping on the fertile work site to make it thin.

Further, since the worker does not need to enter the work area at all, the burden on the worker and the danger can be remarkably reduced. In addition, seed sowing, fertilization, and pesticide spraying can be easily and evenly performed without using an airplane, which prevents damage to power lines and towers and spraying of pesticides onto residential areas due to wind. be able to. Further, even in a markedly muddy wetland such as a lotus field, there is no need for an operator to enter or use a ship or the like, so that the work efficiency is improved and the work can be performed safely.

Further, by utilizing the linearity of the pair of track members arranged in the vicinity of both sides of the work area and the linearity of the long-length supporting member extending over the work area, the land in the work area can be easily maintained on the same plane. can do. Further, since the pair of track members and the long support member are arranged so as to be orthogonal to each other, the track member and the long support member can be positioned with high accuracy on a secondary coordinate plane with two orthogonal axes, and It can also be used for complex complicated movements, and can be applied to, for example, sowing seeds for making a flower bed with a complicated pattern.

Further, since the movement status of the first self-propelled device and the movement status of the second self-propelled device can be easily controlled electrically, computerization and automation of agricultural work can be achieved, and industrialization of agriculture can be achieved. Can be achieved. In particular, since automation can realize unmanned work, it is less affected by the weather, continuous operation becomes easier, and unmanned automatic work at night becomes possible. In addition, since there is no influence from the work site, it is possible to eliminate the stuffiness, waste, and unevenness that have conventionally occurred in various forms, and it is possible to easily standardize and simplify the work. For this reason, it is possible to significantly reduce the rice price of producers, and it is possible to solve various rice problems and international friction at once.

Furthermore, since the weight of the working means does not need to be applied to the working area, it is possible to prevent the working area from becoming thin due to its weight even if the working means is increased in size, so that the working means can be increased in size. Further, since the drive source of the mobile work device is electric, energy saving can be realized by using a power source charged by a solar battery.
