Therefore, conventionally, for example, a harvester without an automatic threshing device, a trailer attached to a tailor or a tiller, a trailer attached to a hitch of a tractor, and the like to effectively use a working machine as a carrier truck It has been known.

However, all of these are large in size, and the landing surface of the running body such as tires is too large to step on nearby vegetables when moving in the field, or have poor stability on sloping ground. There's a problem.

On the other hand, Japanese Patent Application Laid-Open No. 60-70002 discloses a small-sized walking paddy working machine having a small contact surface of running wheels for a carriage. However, since this is a two-wheel drive on the left and right, stability on sloping ground has not been solved, and it is said that traveling in soft cultivated land etc. with unstable front-back posture and unevenness is troublesome. There is a drawback, and there is also a problem that the float that is still attached to the machine body is likely to be deformed or damaged by colliding with an obstacle.

[Means for Solving the Problems] The present invention was conceived with the object of providing a transporting trolley using a walking paddy working machine capable of eliminating these drawbacks in view of the above-mentioned circumstances. In a walking type paddy field working machine which is engine-driven and is configured to vertically move a pair of left and right running wheels by means of a hydraulic mechanism, below a paddy field working section arranged behind the running wheels. Is a space without float by removing the float for sliding the field, and in the space, a tail wheel that grounds between the vertical movement range of the traveling wheels is rotatably provided, and a loading platform is attached to the upper part of the fuselage. It is configured as a carrier and the aircraft attitude is
It is characterized in that it can be transformed back and forth by the operation of the hydraulic mechanism.

Further, in a walking type paddy field working machine which is an engine driven type and is configured such that a pair of left and right running wheels can be moved up and down by a hydraulic mechanism, a lower part of a paddy field working section arranged behind the running wheels is provided. , The float for sliding the paddy field was removed to create a space without a float, and in this space, a tail wheel that grounded between the vertical movement range of the traveling wheels was rotatably provided, and a loading platform was attached to the upper part of the fuselage. In addition to being configured as a transport vehicle, a detector is provided on the machine body to detect swinging in the front, rear, left, and right directions, and the hydraulic mechanism is operated based on the detection result of the detector to horizontally maintain the machine body posture. It is also what

In the present invention, the walking type paddy work machine is used by being configured as a transport vehicle during idle periods, and the machine body is always kept horizontal even on a sloping land so that it can be easily handled.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 is a carrier body using a walking paddy working machine, and a loading platform 2 is attached to the upper part of the body corresponding to the auxiliary seedling table mounting portion of the walking paddy working machine, which is used at the time of rice planting. Float 20 has been removed. Further, a tail wheel 4 is rotatably attached to a central rear fulcrum between the traveling wheels 3, and the mounting height of the tail wheel 4 is set in a state in which the body 1 is in a substantially horizontal posture and in a vertical movement position. It is preferable to position it so that it is grounded when it is approximately in the middle. Depending on the model,
Since the traveling loci of the traveling wheels 3 are different, to be precise, as shown in FIG. 2, it is set so as to be at a substantially intermediate position of the angle formed by the tangents between the traveling wheels 3 and the tail wheel 4 at the upper and lower limits of the body 1. To be done. Reference numeral 5 denotes a hydraulic traveling lever,
It is well known that the height of the machine body 1 can be appropriately adjusted by the operation of. Reference numeral 6 denotes a plurality of balance weights that are detachably mounted on the engine frame 7 that fixes the engine 30 installed from the front center of the machine body 1 from both sides.

In the figure, 31 is a main cylinder for controlling the lifting and lowering of the machine, 32 is a sub-cylinder for horizontal controlling of the machine, 33 is a balance arm, 34 is a hydraulic valve for lifting control, 35 is a hydraulic valve for horizontal control, and 36 is a hydraulic control valve.
Is a transmission case.

In the embodiment of the present invention constructed as described, the cargo bed 2
Can be shaped according to the purpose of use,
The horizontal balance on the plane of the aircraft 1 is the engine frame 7
The balance weight 6 can be set approximately by increasing or decreasing the balance weight 6. Then, when traveling on an ascending slope, the hydraulic traveling lever 5 is manually operated to lower the machine body 1, and when traveling on a descending slope, the machine body 1 is raised on the contrary, so that the machine body 1 is always kept substantially horizontal even on an inclined surface. You can carry and run while holding. Moreover, since it uses a walk-behind paddy work machine, it has a small ground contact area for wheels, can be turned rapidly, is easy to handle, and can be effectively used as a power carrier, even in farmlands and narrow areas where vegetables are cultivated. You can operate it freely. Further, since the loading platform does not tilt, the volume in the horizontal plane is always kept substantially constant, and a stable loading amount can be secured.

As described above, in the embodiment of the present invention, the float 20 is detached from the walking paddy working machine to form a space without the float, and the tail wheel 4 is provided at the center of the space in the left-right direction. Since it is mounted and used as a three-wheeled transport vehicle, even in the case of farmland that is soft and has uneven surface, it is driven by the engine 30 and transported while keeping the posture substantially horizontal by using the hydraulic mechanism provided. You can Moreover, since the wheel has a small ground contact area and is capable of turning sharply, it is easy to handle and can be fully utilized as a small power carrier.

Moreover, since the tail wheel 4 is mounted in the space where the float 20 can be removed, the mounting space for the tail wheel 4 can be secured reasonably and reliably, and the float 20 does not exist when used as a transport vehicle. Thus, unlike the case where the float is still attached, the float does not collide with an obstacle, and the float can be protected.

Of course, the present invention is not limited to the above-mentioned embodiment, and instead of the manual operation of the hydraulic travel lever 5, the second embodiment shown in FIG. 3 and FIG. You can also do so. That is, through the spherical bearing 12 in the lower center of the engine frame 7, it is possible to swing back and forth, left and right,

A detection rod 15 for issuing commands for vertical control and horizontal control of the machine body 1 is rotatably connected to a link 19 and a hydraulic mechanism 14 via. Further, balance weights 16 and 17 are attached to the front and rear and left and right side edges of the detection plate 11, respectively. An adjusting rod 18 whose lower end is swingably connected to the left and right weights 17 is also connected to the link 19 and the hydraulic mechanism portion 14, and these weights 16 and 17 are resistances of the respective links 19 and the hydraulic mechanism portion 14. Defeated, and Aircraft 1
The balance is set so that the detection plate 11 is held horizontally without being excessively shaken by the vibration of.

In this case, when the aircraft 1 climbs and tilts, the detector 11 moves to the third

Since it is pushed up in the direction, the body 1 descends and returns to the horizontal state. On the contrary, when the machine body is inclined downward, the detector 11 pulls down the detection rod 15, and the machine body 1 is raised to return to the horizontal state. Further, with respect to the inclination of the body 1 in the left-right direction, for example, on the ground having a low slope on the right side, the detection plate 11 is rotated counterclockwise in FIG. 4 to move the adjustment rod 18 to the right wheel lower side (arrow). Airplane 1 to push in the B direction)
Rotates counterclockwise, and the body 1 is kept horizontal. In the case of terrain with a left slope, the above operation is reversed, and the aircraft 1 is always automatically kept horizontal, so that stable running can be reliably performed.

[Effects and Effects] In short, since the present invention is configured as described above, it is possible to use the walking paddy work machine as a transport vehicle in which the tail wheel is attached to the space formed by removing the float. In addition, even in the case of a farmland that is soft and has rough unevenness, it is possible to carry and travel while maintaining the body posture substantially horizontal by using the engine drive and the hydraulic mechanism provided. Moreover, since the wheel has a small ground contact area and is capable of turning sharply, it is easy to handle, and it can be made to have a function sufficiently as a small power carrier, and the walking paddy work machine can be effectively used during idle periods. .

Moreover, since the tail wheel is installed in the space where the float can be removed, the tail wheel mounting space can be secured reasonably and securely, and the float does not exist when used as a transport vehicle. As in the case where the float is still attached, the float does not come into contact with an obstacle and the float can be protected.
