Abstract

(57) [Summary] [Purpose] To provide an agricultural management work vehicle capable of appropriately moving and arranging a driving unit at a position where harvesting work and the like can be easily performed. [Structure] A driving unit is attached to a traveling device that can travel by itself across ridges such as leaf tobacco by an elevating mechanism.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an agricultural management work vehicle.

[0002]

[Prior art]

 Conventionally, for example, in the leaf picking work of tobacco, while running the ridges of the tobacco in the field, the worker sits on the seat connected to the rear end of the running device and manually removes the tobacco leaf. It is designed so that it can be picked up and springed to a fixed amount and placed on a leaf placement shelf provided on the traveling device.

At this time, a plurality of tobacco leaves are spirally growing upward on the peripheral surface of one trunk, and the lower leaves growing on the lower part of the trunk and the leaves of the trunk Since the true leaves that grow in the middle part and the top leaves that grow on the upper part of the trunk have different leaf qualities, they are separated and stripped.

[0004]

[Problems to be solved by the device]

 However, since the seat on which the operator is seated is fixed at a certain height above ground, one of the two cases, one for removing the lower leaves, one for removing the true leaves, and one for removing the top leaves, is used. In this case, it is possible to set the height to be the optimum height, and the worker can take a comfortable work posture. There was a problem.

Further, since the seat is connected to the rear of the traveling device and towed or is attached to the rear in an extended manner, a large turning radius of the airframe near the headland must be taken, and the seat can be smoothly moved. There was also a problem that the aircraft could not be turned.

In addition, the amount of spring of the harvested leaves is not accurate because it depends on the intuition of the operator, and therefore, it is necessary to measure the weight when performing a drying operation using a dryer or the like. .

[0007]

[Means for Solving the Problems]

 In view of this, the present invention provides an agricultural management work vehicle characterized in that a driving unit is attached to a traveling device capable of self-propelled across a ridge such as leaf tobacco by a lifting mechanism so as to be able to move up and down.

Further, in the present invention, the operating unit is attached to the traveling device so as to be movable back and forth by the advancing / retreating mechanism, and various operations for operating the traveling device, the lifting mechanism, and the advancing / retreating mechanism, respectively, are performed on the operating unit. It is also characterized by the fact that it has a lever, a seat, and a harvest scale.

[0009]

[Action]

 For example, when harvesting leaves from the trunk of a tobacco, an operator seated in the seat of the driver's seat manually scrapes the leaves while the traveling device travels across the ridges of the tobacco.

At this time, the operating unit is movable up and down by an elevating mechanism, and the operating unit is placed at a height at which a worker can easily pick up a moisturizing portion according to each epigenetic portion such as so-called lower leaf, true leaf, and top leaf. Since this can be done, it is possible to easily carry out the work of removing the leaves for each epiphytic site.

Moreover, when the leaf placing rack for placing the picked leaves is at a high position of the traveling device, the placing operation can be performed easily by raising the operation unit to the vicinity of the placing rack. Can be done.

When the driving unit is attached to the traveling device so as to be able to move back and forth in the forward and backward directions by the advancing and retracting mechanism, the driving unit is moved forward by a desired distance during the mopping work to improve workability. On the other hand, when turning the aircraft near the headland, by placing the operating unit as close to the traveling device as possible, the turning radius of the aircraft can be made small and smooth turning work is possible. Can be done.

Further, when the operation unit is provided with various operation levers for operating the traveling device, the elevating mechanism, and the advancing / retreating mechanism, respectively, the seat, and the harvest scale, the operator seated on the seat While operating various levers at hand, he can appropriately operate the traveling device and adjust the up / down / forward / backward position of the operating part. It can be mounted on a leaf mounting shelf or the like.

Since the harvest scale 32 is provided, the operator seated on the seat 31 can operate the various operating levers 35 to 39 while operating the traveling device 1 and moving the main operating unit 2 up and down. The position can be adjusted appropriately, and the picked leaves are weighed by the harvest scale 32 and bundled at a constant weight and placed on the harvest platform 22,23 or the harvest platform 24,25. be able to.

Similarly, in the sub operation unit 3, the up / down / advance / retreat position adjustment can be appropriately performed by a hand operation.

Further, as shown in FIG. 1, the left and right crop loading platforms 22 and 23 are slid forward on the crop loading frames 20 and 21, respectively, so that each operating section 2 and By placing the bundles M of comfortably placed close to the seats 31 and 31 of No. 3, while the harvesting stands 22 and 23 are slid rearward after placing, the harvesting stands 22 and 23 can be slid backward. It is possible to prevent the object loading tables 22 and 23 from interfering with the harvesting work.
