Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a work machine towing vehicle, particularly to a work machine tow vehicle for towing an agricultural work machine such as a rice transplanter.

[Prior Art] Conventional towing vehicles, especially those towing various types of agricultural machinery such as rice transplanters connected to the rear of the vehicle, focus on ease of operation. In many cases, the vehicle body structure and parts arrangement are arranged so that the driving operation is almost satisfactory, but on the other hand, the operation related to the work machinery towed by this vehicle body may be inconvenient or defective. many. For example, when towing a rice transplanter, the forward view of the rice field immediately before seedling planting is obstructed by the bonnet of the engine room in front of the driver's seat of the vehicle, and can only see a considerable distance ahead of the vehicle's travel route. In addition, it is necessary to load supplementary seedlings on the vehicle body and easily transfer and replenish them to the rice transplanter towing them.

In addition, the steering mechanism support frame is usually surrounded by a cover, and there are many meters, lamps, other electrical components, wiring, etc. in this area.Inspection and maintenance of these should be carried out either on the electrical components themselves or in the vicinity. This was often a tedious and difficult task, as the inspection port cover had to be removed to pull out the wiring, etc.

[Objective of the Invention 1] This invention was devised in view of the above-mentioned problems, and it is possible to inspect and maintain electrical components near the steering mechanism support frame without deteriorating the drivability of this trailer vehicle. The purpose is to make it convenient to implement.

[Structure 1 of the Invention] In order to achieve the above object, the present invention provides a work machine for towing a rice transplanter or other work machine by connecting it to the rear of the vehicle body. The upper part of the steering system support frame, which is provided protruding above the floor in front of the driver's seat and which includes electrical components and is surrounded by a cover, is configured to be able to rotate in the front and rear direction integrally with the steering shutter part. When the angle of rotation is increased, it is possible to inspect and maintain electrical components and wiring inside the cover through the opening.
Furthermore, the structure of the vehicle is characterized in that the steering wheel has a tilting function when the angle of rotation is kept within a small range.

[Example] An example of the present invention will be described below based on FIGS. 1 to 5.

The engine 3 of this vehicle, which tows a rice transplanter as the working machine 1, is not installed on the body frame 5 in front of the driver's seat as in the conventional case, but is moved to the rear and placed directly under the driver's seat. There is. If the engine is small, the engine may be located within the vehicle body frame 5. 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 as compact as possible and to expand the floor space around it, the exhaust pipe 13, which conventionally passed through the side of the engine 3 and reached the muffler 11, is connected to the muffler 11 by passing it above the engine 3. , the engine cover 7 on this side is moved to the engine 3 by that amount.
is approaching.

Due to the engine arrangement described above, the upper part of the vehicle body frame 5 in the area in front of and to the side of the driver's seat 9 forms a substantially flat floor surface 15. A steering mechanism support frame 17 is provided protruding from 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 upper and lower parts together with the cover 19, and is connected by a hinge mechanism 21 so as to be rotatable in the longitudinal direction of the vehicle body. Furthermore, a universal joint 25 is provided as a rotation mechanism so that the steering cylinder foot 23 within the support frame 17 can also rotate together with the rotation of the support frame 17.
is provided.

The rotation range is approximately 80'', and when the cover is rotated to its full extent, the divided portion opens wide, and the electrical components and wiring inside the cover 19 can be inspected and maintained through this opening 27. A screw-type fixing mechanism 29 is provided that can fix the rotation range at any angle within about 30 inches, and the steering handle 31 can be adjusted to the optimal height according to the sitting height of the driver. It has a so-called tilt function so that it can be set.

The lower range of the steering mechanism support frame 17 is slightly enlarged, and a gear change 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 side floor surface of the steering mechanism support frame 17.

Due to the above-described arrangement, a wide floor area in front and on the sides of the driver's seat 9 on the vehicle body frame can be secured and can also be used as a work passage. As shown in the figure on the side of the frame, there is a shelf frame body 4 for storing spare seedlings.
The frame 4 with rails (9 frames 49 are attached to both sides of the vehicle body frame) is mounted on the rails (9 frames 49 are mounted on both sides of the vehicle body frame) so that the shelf frame 45 can be moved at any time in the longitudinal direction of the vehicle body.・Automatic locking (not shown) using spring-equipped locking claws and pins so that the shelf frame body 45 mounted on the rail 9 is moved in the longitudinal direction of the vehicle body and is automatically locked at the front and rear positions respectively. A mechanism is provided.

Note that the front end of the floor surface 15 is aligned with the horizontal axis 50 with respect to the front end of the vehicle body.
The engine cover 7 is installed at the rear so that it can rotate freely around the engine.
, the driver's seat 9, the rear wheels 51, and the fenders 52 are integrally configured so that they can be rotated upward and opened. 53
54 is a front wheel operated by a steering handle 31;
1M11 rice seedling tank, 55 is the rod with seedlings, 56
is a float.

As described above, in the above-mentioned construction of this vehicle, the area in front of the driver's seat 9 is a substantially flat floor surface 15, and there is a steering wheel surrounded by a cover 19. Since there is only the mechanism support frame 17, various operating levers, steering handle 31, etc., forward visibility is extremely good, and in particular, the ground in front of this car, rice fields, etc. can be seen right up to the front, making it possible to observe the situation in detail. Easy to do.

In addition, since the side of the driver's seat 9 can also be used as a floor surface or a work passage, the shelf frame 45 for storing spare seedlings can be loaded on the side of the car body and can be moved in the longitudinal direction of the car body, so that spare seedlings can be stored on the car. The shelf frame 45 can be transferred and replenished to the rice transplanter very easily. Similar replenishment of materials for working machines other than the rice transplanter can be easily carried out on the vehicle. Furthermore, as mentioned above, the fact that the side of the driver's seat 9 is the floor surface over a wide area in the front and back direction of the car results in a wide range of footholds when going up and down between the car and the ground, and it is difficult to get on the ridges etc. The ability to move up and down in narrow spaces 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 approximately 80 degrees, creating a large opening that allows for easy and secure access to internal electrical components, wiring, etc. Can be inspected and maintained. In addition, the steering shaft 23 can also be rotated and is equipped with a screw-type fixing mechanism 29 that can be fixed at any angle within a small range of rotation up to 30'.
By raising and lowering the height of the vehicle, a so-called tilt function is activated, allowing the driver to freely select the height according to the sitting height and preference, making it extremely easy to operate the steering wheel.

The present invention is not limited to the embodiments described above, but can be applied in almost the same way to other riding-type work machine towing vehicles for towing various types of work machines, and can exhibit the functions described above.

[Effects of the Invention] As described in detail above, the trailer working machine having the configuration of the present invention can open the opening of the cover by largely rotating the steering mechanism support frame in the front and back direction. It can be opened wide and electrical components, wiring, etc. near the steering mechanism support frame can be inspected and maintained very easily from this opening, and in addition, the steering mechanism support frame can be rotated slightly in the front and rear directions. The height of the steering wheel can be adjusted to suit the driver's body shape and preference, making it easier to operate the steering wheel.As both of these operations are performed by rotating the steering mechanism support frame in the front and rear directions, the steering wheel height is adjusted to suit the driver's body shape and preference. This also has the effect of simplifying the process.
