荷台装置を提供しようとするものである。 In order to solve the above-mentioned conventional drawbacks, the present invention is equipped with a conveyor belt that transports the cargo by placing it on the upper surface, a drive chain that pulls and drives the belt, and also has a guide space in the horizontal joist that is suspended horizontally on the upper surface of the chassis frame. A drive sprocket, which is interlocked with a drive device, is mounted on the inner end of the body with the horizontal joists installed inside the bottom, and the chain is bent and supported through the sprocket, and the body is used to transport cargo. The belt is bent and supported via a driven roller shafted at the projecting end, and the bent end of the chain and the non-conveying end of the belt are respectively inserted into the guide space and connected via a connector. A base is provided above the horizontal joist and slidably supported, and the other bent end of the chain and the conveying side end of the belt are extended over the upper surface of the horizontal joist to connect and fix the base. The device is connected to each platform, and a shielding plate is laid and fixed on the lower surface of the horizontal joist, and the belt and the lower side of the horizontal joist are sealed off with the shielding plate, so that the equipment can be transported without raising the load surface. The belt can be stretched, and the weight can be reduced by reducing the number of parts used to stretch the belt. In particular, a guide space is formed in the horizontal joist exposed to the outside, and the belt and chain are inserted into the space. In this structure, the shielding plate can prevent mud from adhering to the belt and chain, thereby preventing mud from getting caught in the sprocket and drive device and damaging them, or from getting onto the load via the belt. It is an object of the present invention to provide a cargo transport platform device that can eliminate inconveniences such as the adhesion of mud and improve the efficiency of cargo handling operations.
