Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled transport vehicle used for transporting harvested crops, materials such as fertilizers, or various tools during various agricultural operations.

[0002]

2. Description of the Related Art
Self-propelled transport vehicles used in various agricultural work are
A table-like carrier on which a load is placed is supported by a traveling vehicle on crawlers or wheels provided on its lower surface, and the traveling vehicle is driven by an engine mounted on the traveling vehicle to travel. ing.

[0003] However, in this conventional transport vehicle, when the load is loaded on a table-like carrier, the operator must lift the transporter up to the upper surface of the carrier. When unloading an object loaded on a carrier from the carrier, the operator must lift the carrier from a high position on the upper surface of the carrier, and further lift the carrier on the carrier. Since the loaded conveyed object has to be moved to a predetermined position while sliding on the carrier against a large friction, these operations are heavy labor.

In order to reduce the labor required for loading and unloading, some transport vehicles are equipped with an elevating lift at the side of the loading platform to lift and unload the load. However, mounting a lifting lift on the loading platform increases the size of the transport vehicle and increases the weight, so that it is often impossible to get into narrow places such as narrow rice fields or fields. Not only,
There was a problem that the price increased significantly.

The present invention focuses on the fact that a swing plate which is opened and rotated outward is provided around the loading platform, and the loading and unloading of goods to be conveyed is performed using the swing plate. Another object of the present invention is to make it easy to move on a carrier.

[0006]

In order to achieve this technical object, the present invention provides a method of supporting a table-like carrier on which a load is placed by a traveling carriage on crawlers or wheels provided on the lower surface thereof. And, in a transport vehicle configured to drive the traveling vehicle by an engine mounted thereon, at least one of the side surfaces around the loading platform has a tilt plate, and the tilt plate has a loading platform. A plurality of rollers, which are rotatably pivoted in an outward direction with respect to the supporting plate and rotatably supported on an axis parallel to the upper surface of the loading platform, are provided at an appropriate pitch in a direction away from the loading platform. Is provided so that a part of the outer periphery of each roller protrudes from both the front and back surfaces of the tilting plate. "

[0007]

Operation and effect of the present invention In this configuration, the tilt plate is
By rotating outward and tilting so that the tip farther than the loading platform is lower than the top surface of the loading platform,
On the upper surface of the tilting plate, it can be placed at a lower position than the loading platform, and then, while rolling this conveyed object by rolling each rotatable roller projecting on the surface of the tilting plate, By moving with light force along the surface towards the carrier, it can be loaded onto the carrier.

Contrary to this, the object to be transported on the carrier is turned outwardly and moved in a direction away from the carrier along the surface of the tilt plate whose tip is inclined lower than the upper surface of the carrier. By doing so, it is possible to unload from a position lower than the loading platform while rolling and rotating each roller in the tilting plate.

Therefore, according to the present invention, the labor required for loading and unloading the goods to be transported to and from the loading platform can be greatly reduced without providing a lifting lift for the loading platform, thereby improving workability. Since it can be improved, and because it is not provided with an elevating lift, there is an effect that it is easy to get into a narrow place such as a narrow rice field or a field.

The tilt plate is configured to be rotatable in an inward direction with respect to the loading platform, so that the tilting plate is tilted inward so that the loading platform can be tilted. Since the flip plate can be placed upside down on the upper surface, the tilt plate can be stored so as not to protrude upward and outward from the carrier. In this case, since each rotatable roller protrudes also on the surface of the flipped upside down plate, the load placed on the loading platform slides on the back surface of the rolled up plate with a light force. This makes it possible to easily move to a predetermined position and reduce the labor required for moving the conveyed object placed on the carrier on the carrier.

[0011] In particular, as described in claim 3, each roller in the tilt plate is divided into a plurality of roller pieces in the axial direction, so that the transported object is placed on the surface of the tilt plate. When moving along the roller, the load can be easily slid in the axial direction of the roller with a light force, so that the workability can be further improved.

Further, as described in claim 4, the tilt plate is folded in two between a pivot portion of the tilt plate and a tip end of the tilt plate, so that the tilt plate protrudes from the upper surface of the dump truck. Since the height can be reduced, there is an advantage that the obstruction of the field of view by the tilt plate can be reduced when the length from the pivot portion of the tilt plate to the carrier to the tip is increased.

Further, as described in claim 5, the tilt plate is divided into a plurality of tilt plate pieces in the axial direction of each roller, so that some tilt plates are pivoted outward. In doing so, the loading and unloading of the load can be performed, and the remaining tilt plate can be located on the upper surface of the loading platform, so that the transported product can be moved on the loading platform.
There is an advantage that workability can be further improved.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 4 show a first embodiment.

In this figure, reference numeral 1 denotes a self-propelled transport vehicle. The transport vehicle 1 basically includes a table-like carrier 2 and a pair of right and left crawlers as an example of a traveling vehicle. 3, a driving operation unit 4 having an engine 5 for rotating the crawlers 3 and a step platform 6 on which an operator rides are provided. .

The loading platform 2 and the traveling operation operation unit 4
A front plate 7 for the carrier 2 is provided between the front and back sides, and a tilt plate 8 surrounding the side is pivotally mounted on the left and right side surfaces of the carrier 2 so as to be rotatable outward. .
Although not shown, the tilting plate 8 for this side is provided with a detachable lock mechanism for holding the tilting plate 8 in an upright state.

On the rear side surface of the loading platform 2, a lifting plate 9 wider than the lifting plate 8 for the side surface is provided with a hinge 10 so that the lifting plate 9 is moved inward and outward with respect to the loading platform 2. It is pivotally attached in both directions.

The tilt plate 9 can be connected to a pin 11 provided on both left and right side surfaces thereof by connecting an arbitrary portion of a chain 12 having one end engaged with the side of the tilt plate 8 with respect to the side surface of the tilt plate 8 or the like. By detachably engaging, it is configured to be able to be held in an upright state with respect to the loading platform 2 and at an arbitrary position that is opened outward and turned.

As shown in FIG. 3, a plurality of vertical bars 9b extending in a direction perpendicular to the side surface of the carrier 2 are attached to the inside of a surrounding frame 9a forming the periphery, as shown in FIG. And a roller piece rotatably supported by a roller shaft 13 extending in parallel with the side surface of the carrier 2 between the vertical bars 9b. 14 are provided at appropriate intervals in a direction away from the loading platform.

In this configuration, the tilt plate 9 with respect to the rear side surface of the bed 2 is pivoted outward, as shown by the dashed line in FIG. 4, so that the tip end farther than the bed is lower than the upper surface of the bed 2. By tilting as described above, the transported object can be placed on the upper surface of the tilt plate 9 at a height lower than the loading platform, and then the transported object is projected on the surface of the tilt plate 9. While rolling and rotating each of the rotatable roller pieces 14, the roller pieces 14 are moved along the surface of the tilt plate 9 with a light force toward the carrier 2, so that the rollers can be loaded on the carrier 2.

Conversely, the object to be transported on the loading platform 2 is separated from the loading platform 2 along the surface of the tilt plate 9 whose tip is inclined lower than the upper surface of the loading platform by rotating outwardly. By moving in the direction, each roller piece 14 of the tilting plate 9 can be unloaded from a position lower than the loading platform 2 while rolling and rotating.

Further, as shown by a two-dot chain line in FIG. 4, the tilt plate 9 is turned inward and turned upside down on the upper surface of the loading platform 2 so that the lifting plate 9 can be moved upward and downward from the loading platform 2. It can be stored without protruding outward. In this case, since the rotatable roller pieces 14 also protrude from the surface of the flipped up and down plate 9, the load placed on the carrier 2 can be transferred to the roller pieces 1.
It can be easily moved to a predetermined position while sliding on the back surface of the tilt plate 9 provided with 4 with a light force.

Furthermore, the roller pieces 14 of the lifting plate 9 are arranged at appropriate intervals in a direction parallel to the side surface of the loading platform 2, so that the load can be moved along the surface of the lifting platform 9 along the surface of the lifting platform 9. When moving in a direction perpendicular to the side surface, at the same time, it is possible to move the object to be moved in a direction parallel to the side surface of the carrier 2 with a light force.

The provision of the plurality of roller pieces 14 on the tilting plate as described above is different from the above-described embodiment in that
It can be said that, instead of or in addition to the application to the lifting plate on the rear side surface of the loading platform 2, the invention may be applied to one or both of the lifting plates 8 on the left and right side surfaces of the loading platform 2. Not even.

Next, FIG. 5 shows a second embodiment.
