Thus, the traveling pedal 15 is configured.

Further, as shown in FIGS. 1 and 2, an engagement plate 16 is provided on the back surface of the main pedal 11 as an engagement member extending to the back surface side of the sub pedal 13. Thereby, when the tip of the sub-pedal 13 is depressed, both the main pedal 11 and the sub-pedal 13 are rotated counterclockwise about the support shaft 3 via the engagement plate 16 which is engaged with the back surface of the main pedal 11. It has become. When only the tip of the main pedal 11 is depressed, only the main pedal 11 rotates counterclockwise about the support shaft 3.

As shown in FIGS. 1 and 2, the toe board 1 at the tip of the travel pedal 15 has a support plate 17 bent in a U-shape so as to face the tip of the travel pedal 15. It is fixed diagonally. The first as scan topper means on the upper surface of the support plate 17
Stopper bolt 18及beauty second stopper bolt 19 is threaded, clamping the first and second stopper bolt 18 and 19 by a lock nut 20 screwed into said first and second stopper bolt 18, 19 with respect to the support plate 17 It is fixed. The height of the first stopper bolt 18 is higher than the height of the second stopper bolt 19, and the head of the first stopper bolt 18 has the lower surface of the distal end of the sub pedal 13, and the head of the second stopper bolt 19. The lower surface of the tip of the main pedal 11 comes into contact with the main pedal 11.

Therefore, as shown in FIG.
When the pedal 13 is depressed, the pedal 13 hits the head of the first stopper bolt 18 as shown by a dotted line, and is depressed. When only the main pedal 11 is depressed, the pedal 11 is moved as shown by a dotted line. Second
The stopper bolt 19 comes into contact with the head and the depression is defined.

As shown in FIGS. 1 to 3, a connecting piece 21 is provided on the lower surface of the tip of the main pedal 11 so as to be parallel to the longitudinal direction. One end of an oscillating link 22 bent in a crank shape is fastened and fixed to the connecting piece 21 by a pair of bolts 23 and nuts 24. or,
The swing link 22 is inserted into a lower portion of the toe board 1 through a slit 25 formed between the support plate 17 and the support member 2. Then, the swing link 22
A connection pin 26 protrudes from the side surface at the other end of the
A connection fitting 27 is rotatably provided on the connection pin 26.

One end of a connection rod 28 bent in a crank shape is fixed to the connection fitting 27, and a connection fitting 29 is fixed to the other end of the connection rod 28. The connection fitting 29 is connected to the swash plate adjusting shaft 3 of the variable displacement pump 30 as a device.
1 and fixed. The swash plate adjusting shaft 31 adjusts the swash plate angle of the variable displacement pump 30, controls the amount of oil discharged from the variable displacement pump 30, and controls the traveling speed of the vehicle. Therefore, for example, the main pedal 1
When the front end of the pedal 1 is depressed, the main pedal 11 rotates counterclockwise about the support shaft 3, and the front end of the connecting rod 28 is moved to two points by the connecting piece 21 and the swing link 22 as the main pedal 11 rotates. It swings in the direction shown by the chain line. Thereby, the swash plate adjusting shaft 31 connected to the connecting rod 28 rotates clockwise, the amount of oil flowing into the variable displacement pump 30 increases, and the speed of the cleaning vehicle can be increased.

Further, a pin 32 protrudes from a side surface of the swing link 22 inside the connection pin 26 provided at the other end of the swing link 22, and a piston 34 of an air cylinder 33 is formed on the pin 32. It is connected. The base of the air cylinder 33 is rotatably connected to a chassis 35 fixed to the cleaning vehicle body via a connecting plate 36 and a pin 37.

This air cylinder 33 is used for the traveling pedal 15.
When is not depressed, the swing link 22 is positioned at the position shown by the solid line in FIG. 1 by the air cylinder 33 and is held at the neutral position. When the tip of the main pedal 11 is depressed and the main pedal 11 is brought into contact with the second stopper bolt 19, the cleaning vehicle is set at the full forward speed position, and the tip of the sub pedal 13 is depressed to apply the sub pedal 13 to the first stopper bolt 18. The contact time is defined as the cleaning low-speed traveling position of the cleaning vehicle.

Further, as shown in FIG.
When the base end of the main pedal 11 is depressed, the main pedal 11 rotates clockwise about the support shaft 3, and the tip of the main pedal 11 moves upward as shown by the dotted line. Therefore, the tip of the connecting rod 28 swings to a position opposite to the two-dot chain line. for that reason,
The swash plate adjusting shaft 31 of the variable displacement pump 30 can rotate counterclockwise to retreat the cleaning vehicle, and the position of the main pedal 11 is set to the retreat position.

Next, the operation of the traveling pedal in the cleaning vehicle configured as described above will be described. First, when the operator depresses only the tip of the main pedal 11, the main pedal 11 rotates counterclockwise about the support shaft 3. It swings in the direction indicated by the chain line. Therefore, the swash plate adjusting shaft 31 of the variable displacement pump 30 rotates clockwise, and the amount of oil discharged from the inside of the variable displacement pump 30 increases, so that the traveling speed of the cleaning vehicle can be increased.
When the tip of the main pedal 11 is further depressed, the tip of the main pedal 11 hits the head of the second stopper bolt 19 and the rotation of the main pedal 11 is regulated. The maximum speed of the cleaning vehicle is specified. Therefore, the operator can perform the forward operation of the cleaning vehicle by adjusting the depression amount of the main pedal 11 between the neutral position and the forward full speed position.

When the cleaning operation is performed by the cleaning vehicle, when the front end of the sub pedal 13 is depressed, the sub pedal 13 rotates counterclockwise about the support shaft 3. or,
The main pedal 11 is similarly rotated via the engagement plate 16. Therefore, the tip of the connection rod 28 swings in the direction indicated by the two-dot chain line by the connecting piece 21 and the swing link 22.

When the tip of the sub-plate 13 is further depressed, the sub-plate 13 hits the head of the first stopper bolt 18, and the rotation of the sub-plate 13 is regulated. Further, since the height of the first stopper bolt 18 is higher than the height of the second stopper bolt 19, the swing of the tip of the connecting rod 28 is small. Accordingly, since the amount of rotation of the swash plate adjustment shaft 31 of the variable displacement pump 30 is small, the variable displacement pump 3
The amount of oil discharged from zero can be reduced.

As a result, it is possible to perform low-speed running during cleaning by depressing the tip of the sub-pedal 13 and touching the head of the first stopper bolt 18, so that the running plate is kept constant by depressing the foot unlike the conventional case. There is no need to hold and drive at low speed. Therefore, the operation of the pedal can be facilitated, and the speed of the cleaning vehicle at low speed can be stabilized. Further, by loosening the lock nut 20 and rotating the first stopper bolt 18, the distance between the sub-pedal 13 and the head of the first stopper bolt 18 can be adjusted. Can be.
