This engine position may be set within the internal range of the body frame 5 when the engine is small. In this embodiment, as described above, the engine 3 is surrounded by the engine cover 7, and the driver's seat 9 is provided on the engine cover 7. In this case, in order to make the engine cover 7 compact as much as possible and expand the floor area around this, the exhaust pipe 13 that has conventionally reached the muffler 11 through the side of the engine 3 is connected to the muffler 11 through the upper side of the engine 3. , That much engine cover 7 on this side
Is approaching.

Due to the engine arrangement described above, the upper portion of the vehicle body frame 5 in the front and side areas of the driver's seat 9 has a substantially flat floor surface 15. A steering mechanism support frame 17 is provided so as to project on the floor surface 15 in front of the driver's seat 9. The steering mechanism support frame 17 is surrounded by a cover 19 on which electrical components such as meters and various lamps are mounted. The support frame 17 is divided into an upper part and a lower part together with a cover 19 and is connected by a hinge mechanism 21 so as to be rotatable in the front-rear direction of the vehicle body. Further, a universal joint 25 is provided as a rotation mechanism so that the steering shut 23 in the support frame 17 can also rotate together with the rotation of the support frame 17.

The rotation range is about 80 °, and when the rotation range is fully rotated, the split portion is largely opened.
7. From 7 to inspect and adjust the electric components and accessories of the wiring inside the cover 19. Then, the screw type fixing mechanism 29 capable of fixing the rotation range to any angle up to about 30 °
Is provided so that the steering handle 31 has a so-called tilt function so that the steering handle 31 can be adjusted and set to an optimum height according to the seat height of the driving vehicle.

The lower area of the steering mechanism support frame 17 is slightly enlarged, and a gear changeover switching lever 33, a working machine operating lever 35, etc. are provided therein, and a battery 37 is also housed therein. A throttle lever 39 is mounted above the support frame 17. Further, a brake pedal 41, a clutch pedal 43, etc. are arranged on the lateral floor surface of the steering mechanism support frame 17.

With the above-described arrangement, the front and side floor surfaces of the driver's seat 9 on the vehicle body frame can be widely secured and can be used as a work passage. As shown in the figure on the side of the frame, a shelf frame 4 for accommodating spare seedlings
Frames with rails 49 are mounted on both side surfaces of the vehicle body frame so that the vehicle 5 can be placed on the wheels via the wheels 47 and the shelf frame body 45 can be moved in the front-rear direction of the vehicle body at any time. Then, the shelf frame 45 mounted on the rail of the rail-equipped frame 49 is moved in the vehicle front-rear direction and automatically locked at the front and rear positions, respectively. An automatic locking mechanism is provided.

It should be noted that the floor surface 15 has a front end portion with a horizontal axis 50 with respect to the front end portion of the vehicle body.
The engine cover 7, the driver's seat 9, and the rear wheel 51 fender 52 are integrally formed on the rear portion so as to be rotatable and opened upward. 5
3 is a front wheel operated by the steering wheel 31, 5
4 is a seedling tank of the rice transplanter 1, 55 is a rod with the seedlings, and 56 is a float.

As described above, in this riding type work machine towing vehicle, the front area of the driver's seat 9 is a substantially flat floor surface 15 as described above, and the steering mechanism support frame surrounded by the cover 19 is provided here. Since only the body 17, the various operation levers, the steering handle 31 and the like are present, the front field of view is extremely good, and in particular, the ground in front of the vehicle, the paddy field, and the like can be seen up to the immediately preceding range, which makes it easy to observe the situation in detail.

Further, since it can be used as a floor surface or a work passage including the side of the driver's seat 9, the rack frame body 45 for accommodating the spare whistle is loaded on the side of the vehicle body so that it can be moved in the front-rear direction of the vehicle body, and the spare seedlings are mounted on the vehicle. It is very easy to transfer and replenish from the shelf frame body 45 to the rice transplanter. The same material replenishment and the like can be easily performed on the vehicle for work machines other than the rice transplanter. Further, as described above, the fact that the side of the driver's seat 9 is the floor surface in a wide range in the front-rear direction of the vehicle results in a wide range of footing when going up and down between the vehicle and the ground, which results in a ridge road or the like. The operability of raising and lowering in a narrow space has been greatly improved.

Next, the steering mechanism support frame 17 including the cover 19 is divided into upper and lower parts and can be rotated by about 80 °, so that a large opening appears, and it is very easy to make accessories such as electric components and wiring inside. Moreover, it can be inspected and adjusted reliably. In addition, the steering shaft 23 can also be rotated, and a screw type fixing mechanism 29 that can fix the rotating range at an arbitrary angle within a small range up to 30 ° is provided. By raising and lowering the so-called tilt function, the driver can freely select the height according to the coordinates and his / her preference, and the steering operation becomes extremely easy.

The present invention is not limited to the embodiments described above, and can be applied to other riding type work machine towing vehicles for towing various work machines in substantially the same manner, and exhibits the above-mentioned functions.

[Effects of the Invention] As described in detail above, in the riding type work machine towing vehicle using the configuration of the present invention, the opening of the cover is widened by largely rotating the steering mechanism support frame in the front-rear direction. Therefore, the accessories near the steering mechanism support can be very easily inspected and adjusted from this opening without removing the entire cover, and in addition, the steering mechanism support frame can be rotated a small amount in the front-rear direction. As a result, the steering wheel height can be adjusted to suit the body shape of the driver's vehicle and the steering wheel can be easily operated. Therefore, all of these operations are performed by rotating the steering mechanism support frame in the front-rear direction. An effect that the configuration can be simplified can be obtained.
