Description

Technical Field

[0001] The invention relates to transportation equipment, in particular to a belt conveyor connected to a rear-end unloading truck. Background Art

[0002] A belt conveyor is a friction-driven machine that continuously transports bulk materials and is widely used in freight yards at railway stations and docks. However, although existing belt conveyors can transport materials from the feeding point to the train carriage or the cargo hold of a ship, they cannot be directly connected to a rear-end unloading truck, such as the crawler dump truck invented by the inventor. This results in the rear-end unloading truck unloading the goods onto the ground at the belt conveyor, and then transferring the goods to the belt conveyor feed port manually or by a loader, which is very inefficient. In addition, it is impossible to estimate the amount of goods required to fill a carriage. Usually, after a carriage is full, the belt conveyor needs to be transferred to another carriage, but there is still excess goods on the ground, blocking the path for the belt conveyor to transfer. The excess goods also need to be transferred to a new location, which is very inconvenient. Summary of the Invention

[0003] In order to solve the above-mentioned technical problem or one of the technical problems existing in the prior art, the present invention discloses a belt conveyor connected to a rear-end unloading truck, and the technical solution adopted is:

When the stop block descends to below the bell mouth, the cross bar can enter the bell mouth. When the stop block ascends to block the bell mouth, the cross bar is locked with the hook.

[0006] Furthermore, the upward and downward movement of the stopper is controlled by manual operation or by an oil cylinder.

[0007] Furthermore, one end of the horizontal frame is hinged to one end of the inclined frame, tower columns are fixed on both sides of the horizontal frame near the hinge, the cylinder body of the inclined frame lifting cylinder is hinged to the top of the tower column, and the cylinder rod is hinged to the inclined frame; a power unit is fixed on the free end of the horizontal frame, and the power unit includes a hydraulic pump and an internal combustion engine that drives it; a first driven roller is pivotally provided on the horizontal frame near the power unit, a second driven roller is pivotally provided on the horizontal frame near the tower column, and an active roller is pivotally provided on the horizontal frame near the second driven roller. The roller shaft of the active roller is fixedly connected to the output shaft of the hydraulic motor, and a third driven roller is pivotally arranged on the free end close to the inclined frame, and a pressure roller is pivotally arranged on the two tower columns; a grooved roller group is pivotally arranged on the horizontal frame between the first driven roller and the second driven roller and on the inclined frame between the pressure roller and the third driven roller, and the endless conveyor belt is wound around the first driven roller, the second driven roller, the active roller and the third driven roller and is pressed by the pressure roller and supported by the grooved roller group; the endless conveyor belt area between the first driven roller and the pressure roller is the loading area.

[0008] Furthermore, the endless conveying belt passes around the first driven roller clockwise and is pressed by the pressure roller, then passes around the third driven roller and the active roller clockwise and then passes around the second driven roller counterclockwise; and also includes a tensioning roller to adjust the tension of the endless conveying belt.

[0009] Furthermore, the free end of the horizontal frame is pivotally connected to a trailer for road transportation.

[0010] Compared with the prior art, the present invention can be connected to a rear-end unloading truck and can transfer the unloading location by driving the unloading truck to move laterally, thus having strong maneuverability. BRIEF DESCRIPTION OF THE DRAWINGS

When the stopper 404 descends below the bell mouth 403, the crossbar can enter the bell mouth 403. When the stopper 404 ascends to block the bell mouth 403, the crossbar and the hook 400 are locked. The upward and downward movement of the stopper 404 is controlled by manual operation or by a hydraulic cylinder.
