The present invention relates to a conveyor device, in particular, installed in the vehicle's loading box to be used to rotate freely up, down, left and right, and to be driven by the chain assembly, so that the operation is not only accurate, but also can be easily folded and stored in the loading box. The present invention relates to a conveyor apparatus installed in a vehicle loading box.

In general, conveyors are frequently used to continuously transport cargo at a constant speed within a relatively short distance. In particular, it is difficult to transport cargo that is easily damaged or cargo that has a risk of handling.

For this purpose, a conveyor apparatus has been proposed for transporting cargo directly from a loading box of a vehicle loaded with a load that is difficult to handle, that is, as shown in FIG. Pedestal 54 on which the conveyor assembly 53 is mounted to the support 52 fixedly installed at the center) is mounted to be rotated via the pivot shaft 55, and the middle lower portion in the longitudinal direction of the conveyor assembly 53 is rotated. Between the support 52, the length of the connecting bar 57 to adjust the length is fixed to a plurality of belt 58 and the pulley 59 is installed to be driven.

Here, the conveyor assembly 53 is divided into a plurality of bars, that is, the front and rear conveyor frames 62 and 63 around the intermediate conveyor frame 61 to which the bracket 60 is attached so that the connection bar 56 is connected. ), And before and at the ends of the rear conveyor frames 62 and 63, the trays 64 and 65 are coupled to each other, and the conveyor assembly 53 is supported by adjusting the length of the connection via 56. It can be rotated up and down at a certain angle on (52).

Hereinafter will be described the operation of the present invention.

First, the state of use of the conveyor apparatus according to the present invention, as shown in Figure 7 as the conveyor assembly (1) is loaded with the cargo (40) from the loaded vehicle 41 to another vehicle 42 ( In the case of unloading 40, when the motor 27 is driven, the chain assembly 25 also rotates counterclockwise as the sprockets 26 and 26 'rotate counterclockwise, so that the chain assembly 25 also rotates. As shown in FIG. 2, the chain roller 30 of the chain bracket 31 to which the chain pad 35 is attached rolls on the guide rail 29 and rotates on the guide pad 34. When the operator puts the cargo 40 on the tray 13 'and pushes it, the cargo 40 is transported in a supported state due to friction with the chain pad 35 in which rubber is molded. It will be carried to the opposite tray 13 spanning the other vehicle 42.

Therefore, since the worker only needs to pick up the cargo 40 from the tray 13, the worker can safely transport the cargo that is difficult to handle.

However, when the height of the storage boxes of the vehicles 41 and 42 are greatly different, the conveyor assembly 1 should be inclined upward or downward with respect to the horizontal plane. In this case, both sides of the front conveyor frame 8 The length of the connecting bar 14, which is connected to the bracket (8a) on the side, respectively.

That is, when the loading box of the vehicle 42 to load the cargo 40 is much higher than the loading box of the vehicle 41, it is necessary to make the front conveyor frame 8 higher than the rear conveyor frame 9 of the conveyor assembly 1. In the connection bar 14, the clamp 17 is released, the connecting pin 22 is pulled out, the lower bar 16 is pushed into the upper bar 15, and the conveyor assembly 1 is installed. The base 2 is rotated counterclockwise around the pin 6 on the support 4 so that the height of the tray 13 'attached to the end of the front conveyor frame 8 is different from the height of the storage box of the other vehicle 42. When it is reached, tighten the through hole 17 of the lower bar 16, and then turn the handle 37 'to finely adjust the height of the tray 11'.
