BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger work vehicle.

[0002]

2. Description of the Related Art Conventionally, as a form of a passenger work vehicle, there has been a small tractor type vehicle with a small turning space.

This is to make the body structure as compact as possible by providing a driving section having a steering handle and a driver's seat in the front part of the machine body frame, and a motive engine section covered with a bonnet immediately behind it.

The front wheel is attached to the front lower part of the driver's seat to form a steering wheel, while the rear wheel is attached to the lower rear part as a drive wheel, and each wheel is covered with a fender for preventing mud splashing.

Further, in order to make the machine body compact, the tread between the wheels is also made as narrow as possible so that it can run over one ridge.

With the above construction, the above-mentioned passenger work vehicle can perform plowing work, for example, by connecting various agricultural working machines to the rear part of the machine body and running in the field while straddling the ridges.

[0007]

However, the above-mentioned passenger work vehicle still has the following problems.

That is, since the tread between the wheels is narrow, the prime mover itself is also cramped, and various devices including the prime mover are laid out in the space formed between the left and right body frames. The rear wheels mounted near the prime mover are also very close to the fuselage frame.

Therefore, even if the bonnet is opened at the time of maintenance around the prime mover, the working space is small and it is very difficult to clean and repair the inside.

Further, since the rear wheel is close to the side of the prime mover, and the upper part of the rear wheel is covered with a fender for preventing mud splashing, the maintainer around the prime mover is being increasingly used. It was hard to do.

In addition, the mud splashed up by the rear wheels often adheres between the wheels and the machine frame or inside the prime mover,
There was a problem in that even if one tried to wash it off, it would not be left in the cramped configuration as described above.

Further, as described above, since the tread is narrow, there is a possibility that the ridges straddling over may be destroyed by a slight steering wheel operation error during traveling work.

An object of the present invention is to provide a passenger work vehicle which can solve the above problems.

[0014]

According to the present invention, a bonnet for covering a prime mover portion provided at a rear portion of a machine body and a fender for covering upper portions of left and right rear wheels attached to the left and right sides of the prime mover portion are integrally formed. A passenger working vehicle characterized in that a pivotal support portion extending in the left-right width direction is provided at a lower portion of a front end thereof, and the hood and the fender can be integrally opened and closed with the pivotal support portion serving as a pivotal support point.

Further, according to the present invention, a plurality of slits extending in the left-right width direction are formed at intervals in the front-rear direction at the step arranged at the front part of the machine body, and the slits project upward at the periphery of the slit. It is also characterized in that convex edges are formed.

It is possible to open and close integrally.

That is, since the main working vehicle A is small enough to straddle one ridge, the tread between the rear wheels 9, 9 is also small.

Therefore, various devices are laid out in a small space around the prime mover, and the rear wheels 9, 9 are close to the body frame 1, so that mud and the like are generated in the rear wheels 9, 9. It tends to adhere to the airframe frame 1 or inside the motor unit 6.

Therefore, with the above structure, the hood 2 and the fenders 3, 3 can be integrally opened and closed, and the space around the prime mover and between the rear wheels 9, 9 and the body frame 1 can be provided. At the same time, it can be opened greatly, which improves the overall view and makes cleaning such as mud removal and maintenance such as repairs extremely easy.

In the present embodiment, as shown in FIGS. 1 and 2, the bonnet 2 is attached to the rear wheel so as to cover the prime mover section 6.

As shown in FIG. 3, a convex edge 4b protruding upward is formed.

With the above structure, for example, when traveling across a ridge, the ridge may be broken by a slight mistake in driving operation. However, in the passenger work vehicle A according to the present invention, the slit 4a is transparent. Since the driver can visually recognize the field scene, it is possible to perform reliable traveling without breaking the ridges.

In addition, in field work and the like, mud is likely to adhere to the sole of the operator (driver), but since the above-mentioned convex edge 4b serves as a non-slip function, the driver does not get on and off. Safety is improved by not slipping your feet when you step on when driving or while driving.

Moreover, since the convex edge 4b is formed on the periphery of the slit 4a, the mud adhering to the sole of the shoe can be scraped off, and the mud can be dropped to the outside of the machine through the slit 4a. You can keep 5 beautiful.

Next, the steering mechanism of the main working vehicle A and the left and right side clutch / brake mechanisms C, C will be described.

At the same time, the driver can feel that the steering wheel 13 can be lightly held in the straight-ahead position when going straight.

Thus, in this way, even though the construction is simple and compact, the passenger work vehicle A can be surely held in the straight traveling state. For example, when connecting various working machines to the machine body and working in the field, There is no danger of breaking the ridges and work efficiency is improved.

Further, the operating force of the steering handle 13 can be adjusted by the spring force adjusting bolt 95, so that there is no problem.

Next, the left and right side clutch / brake mechanisms C, C and the transmission mechanism L will be described.

Left and right side clutch / brake mechanism C, C
As shown in FIG. 6, is mounted on the left and right traveling axles 83, 83 connected to the mission unit 31.

That is, the base ends of the traveling axles 83, 83 facing each other are formed in a spline shape, and the base ends are formed by bearings 84, 8
A side clutch gear 85 is loosely fitted so as to hold the bearing 84 while supporting the shaft through the shaft 4.

Further, right and left sliding collars 86, 86 are spline-fitted to the base ends of the traveling axles 83, 83, and the sliding collars 8
6,86 are urged by the springs 87,87 toward the side clutch gear 85 in the meshing direction so that the clutch is engaged.

Further, as shown in FIG. 5, the sliding collars 86, 86 have left and right clutch arms 79, 7 formed in a substantially V shape.
9 is interlockingly connected via connecting shafts C1 and C1 so that it can be slid on the traveling axles 83 and 83 against the springs 87 and 87 by an external operation to disengage the side clutch gear 85. The clutch can be disengaged.

Further, a multi-plate brake 88 is provided on each of the left and right ends of each of the left and right sliding collars 86, 86, and one contact surface of each of the sliding collars 86, 86 contacts the multi-plate brake 88. I try to contact them.

Therefore, when the side clutch is disengaged, it is advisable to move the sliding collar 86 outward. When the sliding collar 86 is moved outward, the collar 86 presses the spring 87 and activates the multi-plate brake 88. be able to. Then, when the sliding collar 86 returns to the original position, the braking force of the multi-plate brake 88 disappears and the side clutch is re-engaged. In FIG. 6, reference numeral 82 is a rear axle case, and 89 is a main transmission gear group.

On the other hand, the transmission mechanism L is interlocked with the center gear 75 of the front wheel steering device S, and the front wheels 7,
The left and right side clutch / brake mechanisms C and C are connected / disconnected according to the disengagement angle of 7 and the rear wheel
It is possible to apply a braking force to 9,9, and as shown in FIG. 5, a part thereof is substantially overlapped with the front wheel steering system S.

That is, one end of the buffer rod 76 is rotatably connected to the left side of the boss portion 71a of the steering arm 71 with a certain distance, and the other end of the buffer rod 76 is connected to the left and right clutch arms 79 described above. The crank 78, which is interlockingly connected with the 79, 79, is connected. Reference numeral 81 is a buffer spring provided in the middle of the buffer rod 76.

The center of the crank 78 is pivotally supported by a pivot 78b, and the other end of the buffer rod 76 is connected to the pivot 78b.
It is rotatably connected to the right side of the vehicle with a certain distance.

Therefore, the steering arm 71 and the crank 78 are obliquely supported by the buffer rod 76 with respect to the boss portion 71a which is the swing center of the steering arm 71 and the pivot shaft 78b of the crank 78. Therefore, the swinging direction of the steering arm 71 and the swinging direction of the crank 78 are opposite to each other.

Further, engaging pins 78 are provided at both ends of the crank 78.
The engaging pins 78c, 78c are connected to the left and right side clutch operating rods 80, 80, respectively.

80a, 80a are left and right side clutch operating rods
It is a pin engaging part continuously provided at the base end of 80,80, and long holes 77,77 are formed in the pin engaging parts 80a, 80a, and the engaging pins 78c, 78c are formed in the long holes 77,77. Engaged.

On the other hand, the left and right side clutch operating rods 80, 8
The 0 end is the left and right side clutch / brake mechanism.
The left and right clutch arms 79, 79 connected to C, C via connecting shafts C1, C1 are interlockingly connected.

With the above structure, the steering wheel 13
When the steering arm 71 is rotated, the steering arm 71 horizontally swings at a predetermined steering angle, and the front wheels 7, 7 can be steered at a predetermined turning angle. And the forward / backward movement of the buffer rod 76 causes the crank 78 to horizontally swing in the direction opposite to the swinging direction of the steering arm 71.

The horizontal swinging of the crank 78 swings the left and right clutch arms 79, 79 via the left and right side clutch operating rods 80, 80, and the connecting shafts C1, C1 connected to the base ends of the clutch arms 79, 79. Is rotated, and the side clutch mechanisms of the rear wheels 9, 9 are engaged / disengaged.

When the steering handle 13 is further rotated, the swing of the steering arm 71 and the crank 78 becomes large, and the angle at which the connecting shafts C1, C1 of the left and right side clutch / brake mechanisms C, C rotate becomes large. Thus, the left and right side clutch / brake mechanisms C, C perform the braking action as described above, and the braking force can be applied to the rear wheels 9, 9.

For example, when the steering handle 13 is rotated to the left (counterclockwise), the steering arm 71 swings to the right (clockwise), and the left and right drag rods 72 and 73 move.
The front wheels 7,7 act on the towing side and the pushing side, respectively.
Turn to the left (counterclockwise) to make a left turn, and when the steering handle 13 is further rotated to the left, the brake mechanism of the left side clutch / brake mechanism C acts and the left rear wheel 9 Has braking power.

At this time, the braking force can be arbitrarily set by the buffer spring 81 provided in the middle of the buffer rod 76, and the mission portion 31 is not damaged by the stroke of the buffer rod 76 or the like. Can be prevented.

With the above structure, the brake can be easily turned only by operating the steering wheel 13 during normal running, and a safe small turn is possible without fear of an erroneous operation, and the feel at the time of turning is improved. .

By the way, as shown in FIGS. 1 and 2, the passenger work vehicle A according to the present embodiment is provided with a pair of left and right side clutch handles H, H at the front end of the machine body. The left and right side clutch levers H1 and H1 are attached to the left and right side clutch / brake mechanisms C and C, respectively.

Therefore, the left and right side clutch / brake mechanisms C, C can be operated by the steering of the steering handle 13 attached to the steering column 11 and also by the left and right side clutch levers H1, H1.

That is, as shown in FIG. 5, side clutch wires having their base end portions connected to the left and right side clutch levers H1, H1 are respectively attached to the respective tip end portions of the pin engaging portions 80a, 80a of the transmission mechanism L described above. The tips of W and W are crossed and connected. W1 and W2 are the outer and inner parts of the side clutch wires W and W.

With the above structure, for example, when the side clutch wire W is pulled by operating the left side clutch lever H1, the crank 78 horizontally swings counterclockwise (counterclockwise), and the horizontal swing causes the right side clutch to swing. The right clutch arm 79 swings via the clutch operating rod 80, the connecting shaft C1 of the left side clutch / brake mechanism C connected to the base end of the arm 79 rotates, and the side clutch mechanism of the left rear wheel 9 When the connection shaft C1 is connected / disconnected and the connecting shaft C1 is further rotated, the left side clutch / brake mechanism C performs the braking action as described above, and the braking force can be applied to the left rear wheel 9.

When the right side clutch lever H1 is operated, braking force is applied to the right rear wheel 9.

Therefore, the driver gets off the vehicle and lifts the side clutch handles H, H to float the front wheels 7, 7, support the vehicle body only by the rear wheels 9, 9, and appropriately adjust the left and right side clutch levers H1, H1. By operating it, a very small turn is possible, and it is possible to easily get into an adjacent strip.

Therefore, when turning in the vicinity of the headland, the length of uncultivated land can be reduced, and the effective acreage of the field can be increased.

Further, unlike a steep turn made by steering with the steering wheel 13, there is no danger of falling and it is safe.

Further, the side clutch handles H, H are
As shown in FIG. 7 and FIG. 8, the frame-shaped front hitch 1a detachably attached to the front end of the machine body frame 1 is attached to the left and right end faces so that the vertical position can be changed.

That is, on the left and right end faces of the front hit 1a, a pin insertion hole 96 that serves as a pivot fulcrum, and two positioning pin insertion holes 96a located below the pin insertion hole 96,
96b each, while both side clutch handle
Pin insertion holes 97 corresponding to the pin insertion holes 96 and two positioning pin insertion holes 96a and 96b are provided at the rear ends of H and H, respectively.
Positioning pin insertion hole that can selectively correspond to any of
97a and mounting plate H3 are formed in series, and front hitch 1a
Side pin insertion hole 96 and mounting plate H3 side pin insertion hole 97 correspond, and one of the positioning pin insertion holes 96a and 96b on the front hitch 1a side and the positioning pin insertion hole 97a on the mounting plate H3 side And the J-shaped connecting pin P is inserted so that the side clutch handles H, H can be connected to either the upper side or the lower side.

Also, H4 uses the connecting pin P for the front hitch 1a.
These are springs that are biased to the side, and are arranged on the longitudinal sides of the connecting pins P 1 and P 2, respectively.

With the above structure, the side clutch lever H
When using 1, H1, the side clutch handles H, H are connected so that they are located on the lower side. For example, when the passenger work vehicle A is stored in a barn, etc., the handles H, H are located on the upper side. If so, the total length of the passenger work vehicle A is shortened and it becomes easy to store the passenger work vehicle A.

If the side clutch handles H, H are positioned on the upper side as described above, even if the side clutch handles H, H hit the front wall or other obstacles when stored in a barn or the like, the side clutch lever is first Since H1 and H1 come into contact with each other and the levers H1 and H1 are pushed in the direction to disengage the clutch, power transmission is cut off, which is safe.

Further, since the side clutch handles H, H are attached to the left and right end faces of the front hitch 1a, there is no problem even when the front weight or the like is attached to the front hitch 1a.

When the side clutch handles H, H are removed from the front hitch 1a, a front working machine or the like can be connected to the front hitch 1a.
