Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a freight vehicle with a conveyor device in which a pair of left and right conveyor devices are provided at the bottom of a luggage box mounted on a vehicle body.

(B) Conventional Technology As shown in FIG. 3, a conventional freight vehicle with a conveyor device has a pair of left and right conveyor devices (03) (at the bottom of a luggage box (02) mounted on a vehicle body (01). 03) is provided, and a space portion (05) extending in the front-rear direction is provided between the pair of left and right conveyor devices (03) (03) on the floor plate (04) of the luggage box (02).
Had.

(C) Problem to be Solved by the Invention Therefore, when the load in the packing box is discharged by the pair of left and right conveyor devices, there is a problem that the load remains in the space portion and the entire amount cannot be discharged. When traveling in, there was a problem that a pair of conveyer devices entered into the space portion to cause lateral roll, and the conveyer devices collided with each other to be damaged.

Therefore, an object of the present invention is to provide a projecting member in the space to prevent the remaining amount when discharging a load and to prevent damage due to rolling of the conveyor device during traveling with an empty load.

(D) Means for Solving the Problem In order to solve the above-mentioned object, the present invention provides a freight vehicle with a conveyor device in which a pair of left and right conveyor devices are provided at the bottom of a luggage box mounted on a vehicle body, wherein the conveyor device is A pair of left and right endless chains, and a plurality of scraping members mounted at appropriate intervals in the front-rear direction between these chains, and a chain on the center side of the pair of left and right conveyor devices on the floor plate of the packing box. In between, a mountain-shaped projection member close to these chains is provided in the front-back direction on the floor plate, and the chain is positioned above the lower end of the projection member to correspond to the inclined surface of the projection member. .

(E) Action When discharging the load, when the chain is driven, the scraping member moves, and the load accumulated on the floor plate is caught and discharged backward.

When the discharge comes near to the end, the load on the protruding member slides down to the left and right and is discharged to the rear.

Also, while traveling with empty load, the conveyor device sways to the left and right, but the chain abuts the inclined surface of the protruding member and moves upward,
The collision is softened and the chain is prevented from being damaged.

(F) Example Hereinafter, an example of the present invention will be described with reference to the drawings.
FIG. 1 shows a freight vehicle with a conveyor device according to the present invention, (1)
Is a packing box mounted on the vehicle body (2), the upper part of the packing box (1) is opened for loading a load, and the rear door (3) for opening and closing the discharge port is provided behind the packing box (1). ing.

A pair of left and right conveyor devices (4) and (4) are provided at the bottom of the packing box (1) for discharging the load backward.

Since the conveyor devices (4) and (4) have the same structure on the left and right sides, the right conveyor device (4) will be described.
A pair of left and right endless chains (5) and (5) are provided at the bottom of the chain so that the chains (5) and (5) moved upward move on the floor plate (6) of the packing box (1). There is.

A plurality of raking members (7) with proper intervals in the front-rear direction are connected between the pair of left and right chains (5) (5), and the raking members (7) are located above. Sometimes the lower surface of the scraping member (7) ... Slides on the floor plate (6).

When the scraping members (7) are located below, between the upper main girder (8) and the lower main girder (9) provided between the floor plate (6) of the luggage box (1) and the vehicle body (2). To move.

(10) is a space (11) generated in the front-back direction on the floor plate (6) of the packing box (1) between the chains (5) and (5) on the center side of the pair of left and right conveyor devices (4) and (4). The projection member (10) provided with an angled cross section is welded in a slab shape on the floor plate (6) so that the chain (5) (5) on the center side is located below the lower end of the projection member (10). Positioning is made to correspond to the inclined surface of the projecting member to prevent the remaining amount when discharging the load, and to prevent damage to the chain due to rolling of the conveyor devices (4) (4) during traveling when the load is empty. . By the way, in this embodiment, the projecting member has an angled cross section, but a circular cross section has the same effect.

The present invention has the above-described structure, and the operation will be described next. First, when carrying and discharging the load, the load is loaded from above the packing box (1) with the door (3) closed. To do.

After the load is stored in the packing box (1), it is transported to the discharge place.

After opening the door (3) at the discharge location, the chain (5) ……
Drive.

A plurality of scraping members (7) by swinging the chain (5) ..
... moves, catches the load accumulated on the floor plate (6), and discharges it backward.

When the discharge comes to the end, the load on the protruding member (10) slides to the left and right without accumulating on the protruding member (10) and is discharged rearward by the left and right scraping members (7) and (7). , There is no load left.

If the conveyor device (4) (4) sways to the left and right during traveling when the vehicle is not loaded with load, the chains (5) (5) on the center side are inclined to the inclined surface of the protruding member (10). It abuts and moves upwards, softening the collision and preventing damage to the chain.

(G) Effects of the Invention As described above, according to the present invention, since the protruding member is provided on the floor plate of the luggage box between the chains on the center side of the pair of left and right conveyor devices,
When the load is discharged, the load can be discharged entirely without leaving the load on the protruding member.

Even if the conveyor device is swayed to the left or right even when traveling with an empty load, the chain on the center side contacts the inclined surface of the protruding member and moves upward, softening the collision and preventing damage to the chain. .
