Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo handling pedal lower portion cleaning device for discharging dirt, mud, dust and the like (hereinafter referred to as "sand and the like") accumulated under a cargo handling pedal of a skid steer loader. is there.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional skid steer loader. In this figure, reference numeral 1 is a steering lever for traveling operation, and reference numeral 2 is a cargo handling pedal for cargo handling operation. That is, traveling of the skid steer loader is performed by lever operation, and cargo handling work is performed by pedal operation.

[0003]

Since the skid steer loader as described above often handles soil and the like, the soil and the like are likely to accumulate in the lower portion of the cargo handling pedal 2. However, since the cargo handling pedal 2 is arranged at a position one step lower than the front step 3 for getting in and out, and the side of the operator's cab is closed by the wire net 4, the sand and the like at the bottom of the cargo handling pedal 2 It was difficult to discharge the car outside the vehicle.

Therefore, an object of the present invention is to provide a cargo handling pedal lower part cleaning device which can easily discharge the earth and sand accumulated in the lower part of the cargo handling pedal to the outside of the vehicle.

[0005]

In order to achieve the above object, the present invention provides a skid steer loader having a pedal lock device for locking a cargo handling pedal, wherein a plate provided with an opening is provided below the cargo handling pedal. An opening which is reciprocally arranged on the floor plate of the driver's cab, reciprocates the plate in conjunction with the pedal lock device, and which coincides with the opening of the plate when the pedal is locked, but is closed by the plate when the pedal lock is released. Is formed on the floor plate of the cab.

[0006]

The pedal lock device is a device for locking the cargo handling pedal when the driver is not in the driving posture. By interlocking a plate having an opening with this pedal lock device, the pedal locking device can be installed at the bottom of the cargo handling pedal when the pedal is locked. It is possible to open the opening provided on the floor plate of the cab. Through this opening, the earth and sand accumulated in the lower part of the cargo handling pedal can be discharged to the outside of the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the drawings.

1 and 2 show the bottom of the operator's cab of a skid steer loader to which the present invention is applied.
Is a cargo handling pedal, and is swingably supported between a pair of left and right pedal support brackets 12 fixed to a cab floor plate 11.

Reference numeral 13 is a pedal lock device. The pedal lock device 13 includes a rotary cylinder 15 rotatably supported by a support bracket 14 in front of the cargo handling pedal 10, and a lock bar 16 extends from the rotary cylinder 15 in the radial direction. A lever 17 extends from the front part of the rotary cylinder 15, and the tip of the lever 17 is articulated to the tip of a rod 20 of a solenoid 19 via a link mechanism 18. A spring 21 is incorporated in the link mechanism 18,
The rotating cylinder 15 is constantly urged to rotate in the arrow A direction. The solenoid 19 is energized by an appropriate means (for example, a limit switch provided on a buckle of a safety belt) when the driver sits on a driving seat (not shown). Therefore, when the driver is away from the driver's seat, the lock bar 16 is rotated by the action of the spring 21 to the state shown in FIG. It is designed to lock 10. Further, when the driver is seated on the driving seat and is in the driving posture, the rod 20 of the solenoid 19 is retracted against the spring force of the spring 21, and the link mechanism 1
The rotary cylinder 15 is rotated in the direction of arrow B via 8 to separate the lock bar 16 from the lock plate 22. FIG. 1 shows this pedal lock release state.

A lower part of the cargo handling pedal cleaning device 30 according to the present invention.
Is adapted to interlock with the pedal lock device 13, and is a rectangular plate 31 disposed between the pedal support brackets 12 and on the operator cab floor plate 11 below the cargo handling pedal 10.
have. As shown in FIG. 3, the plate 31 is supported by a guide 32 fixed to the operator cab floor plate 11 so as to be slidable forward and backward, and its front end portion extends from the rotary cylinder 15 of the pedal lock device 13. It is connected to the second lever 33 via a link 34. Therefore, when the pedal lock device 13 is operated and the rotary cylinder 15 is rotated,
The plate 31 can also reciprocate back and forth in accordance with the movement.

Further, the plate 31 is provided with an opening 35, and at the position when the pedal is locked (the position in FIG. 2), this opening 35 is the opening 3 provided in the operator cab floor plate 11.
It is supposed to be aligned with 6. On the other hand, at the position when the pedal lock is released (the position in FIG. 1), the opening 35 of the plate 31 is moved forward of the opening 36 of the cab floor plate 11, so that the opening 36 of the cab floor plate 11 is closed.

As is apparent from the above, the lower cargo handling pedal cleaning device 30 having such a structure is provided outside the vehicle on the lower side of the cargo handling pedal 10 when the driver leaves the driver's seat and the skid steer loader is not in the operating state. Since a hole leading to the vehicle is formed, it is possible to sweep dirt and the like out of the vehicle through this hole. Further, when the vehicle is in an operating state, the pedal lock device 13 releases the pedal lock and moves the plate 31 forward to close the opening 36 of the driver's cab floor plate 11. There is also no intrusion from.

In the above embodiment, the plate 31 of the cargo handling pedal lower part cleaning device 30 is linked to the pedal lock device 13 via a link mechanism, but it may be linked to other means, for example, electrically. .

[0014]

As described above, according to the present invention, when the skid steer loader is not in operation, a hole is formed in the lower portion of the cargo handling pedal. It can be discharged, and the cab can be kept clean at all times. Also, since the hole is closed during operation, there is no concern that dirt or the like will enter from below the vehicle body.
