JPH10329720A - Travel control device for conveying work vehicle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the movement of a worker and conduct the efficient work by providing travel action tools traveling a travel device for the prescribed distance or for the prescribed time when kept in contact from the side around a deck in a conveying work vehicle provided with the travel device at the lower section of the deck. SOLUTION: A deck 1 is provided with a travel device 2 constituted of the right and left drive wheels 4, 4 on the rear side and the right and left caster wheels 5, 5 on the front side, and the drive wheels 4 are travel-controlled by the actions of a travel switch 7 and a speed set switch 8 via a control box 6. Handle bars 9, 10 are removably provided on the rear side face of the deck 1, the right/left turn of the caster wheels is locked when the handle bars 9, 10 are inserted into the deck 1 side, and a linear travel can be stably made. Touch sensors (travel action tools) 3 turning a switch on when kept in contact are provided on the right and left side faces of the deck 1, and the drive wheels 4 are driven and traveled for the prescribed distance or for the prescribed time when the switch is turned on.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling control device of a transport vehicle used for harvesting vegetables while traveling in a field or the like.

[0002]

2. Description of the Related Art As a transportation work vehicle used for harvesting vegetables, there is a high-floor type transportation vehicle having wheels running in furrows and having a raised loading surface. This transport vehicle is equipped with a maneuvering device behind the loading platform, moves to the harvesting area of the field and stops,
When the nearby vegetables are harvested, they will move to another harvest site.

[0003]

When the above-mentioned vegetable harvesting and transporting vehicle moves, an operator must operate a steering operation tool provided on the rear side of the loading platform. For this reason, it is necessary to move from the harvest position on the left and right sides of the bed to the rear side of the bed.
SUMMARY OF THE INVENTION It is an object of the present invention to reduce the movement of an operator so that an efficient operation can be performed.

[0004]

According to the present invention, in a transport work vehicle provided with a traveling device 2 below the loading platform 1, the traveling device 2 is brought into contact with the periphery of the loading platform 1 from the side for a predetermined distance or a predetermined time. Is provided.

[0005]

When the harvesting operation is performed by the transport vehicle having the above-described configuration, first, the harvesting position of the vegetable field is moved, stopped, the surrounding vegetables are stacked on the loading platform, and the harvesting position is further moved. In this case, the traveling operation tool 3 provided around the loading platform 1 is moved and stopped by a predetermined distance, for example, about 3 m by touching the traveling operation tool 3 with a hand or a part of the body. become. In this way, the operation of repeating running and stopping the harvesting operation can be easily and quickly performed, and the efficient harvesting operation can be performed.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings. The loading platform 1 is a flat planar platform and has a traveling device 2 including lower left and right driving wheels 4 and 4 and lower front and left and right caster wheels 5 and 5. The drive wheels 4 and 4 are driven by a motor, and a control box 6 is provided on the rear side of the carrier 1 so that the travel can be controlled by a travel switch 7 and a continuous setting switch 8. Handle bars 9 and 10 are provided on the rear side of the loading platform 1 so as to be able to be inserted and removed. When the handle bars 9 and 10 are inserted into the loading platform 1, a hole is provided on a pivot shaft 11 whose tip is pivotally supporting the caster wheel 5. 12 so that the caster wheel 5 does not rotate left and right, so that straight running can be stably performed.

During traveling on the road, the handle bars 9, 10 are pulled out, and the caster wheels 5, 5 are turned left and right so that they can turn. The left and right sides or the front side of the loading platform 1 are provided with a touch sensor that is turned on by contact, that is, a traveling operation tool 3. When the operator's body comes into contact with the touch sensor 3, a timer operates to drive the motor. The vehicle runs by driving the drive wheels 4 and 4 and stops when the timer expires. The traveling distance can be changed by changing the time setting of the timer.
