It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the utility model provides a dump truck, which comprises a truck body 1 and a truck bed 3;
as shown in fig. 5-9, a blanking hole 34 for material to flow out of the compartment 3 is arranged on the bottom of the compartment 3;
as shown in fig. 1, the lower end of the carriage 3 is provided with the discharging device 2 for discharging the material flowing out from the discharging hole 34 from the vehicle, the discharging device 2 is installed on the chassis of the vehicle body 1, the carriage 3 is installed on the discharging device 2, the discharging structure design enables the discharging to be carried out only by starting the discharging device 2, the carriage 3 is not moved, the whole vehicle body 1 is not moved, and therefore the discharging mode is safer than that of the traditional method of lifting the carriage 3 by adopting a hydraulic cylinder, and the carriage 3 can be properly filled with a plurality of powdery materials because the problem that the carriage 3 cannot be lifted by the hydraulic cylinder is not worried.
For the convenient design that ordinary cargo heavy-duty car repacking cost utility model discloses, fixed connection can be dismantled with the chassis of automobile body 1 to discharge apparatus 2, and fixed connection can also be dismantled with discharge apparatus 2 to railway carriage 3, for example bolted connection.
Specifically, as shown in fig. 2 to 4, the discharging device 2 includes:
two parallel cross beams 21 fixedly mounted on a chassis of the vehicle body 1;
a plurality of mutually parallel belt rollers 22, both ends of the belt rollers 22 being rotatably mounted on the two cross beams 21;
the motors 23 are in transmission connection with the belt rollers 22 and are used for driving the belt rollers 22 to rotate, the motors 23 are fixedly arranged on the cross beam 21, and the plurality of motors 23 can ensure the normal work of the discharging device 2;
the conveying belt 25 is tightly sleeved on the belt rollers 22 and is driven by the belt rollers 22 to rotate so as to unload the materials from the vehicle; and
and a tensioning device for keeping the conveyor belt 25 constantly tensioned.
In order to prevent the conveyor belt 25 from being crushed by the material, the distance between two adjacent belt rollers 22 should be designed to be small.
In order to facilitate the operation of the unloading device 2 controlled by the driver, the motor 23 can be a hydraulic motor, and at this time, the unloading device 2 further comprises an oil pipe 24 connecting the hydraulic motor and the hydraulic pump of the vehicle body 1, so that the unloading device 2 can be powered by the hydraulic pump of the dumper.
As shown in fig. 2 to 4, when the motor 23 is a hydraulic motor, the tensioner includes:
sliders 28 which are rolled over both ends of the belt roller 22 at the end of the cross beam 21;
a slide groove 27 provided on the cross beam 21, and a slider 28 horizontally slidably mounted in the slide groove 27; and
a hydraulic cylinder 26 fixedly mounted on the cross beam 21 for pushing the slide block 28 to horizontally slide in the slide groove 27, wherein the slide block 28 moves to drive the belt roller 22 mounted thereon to synchronously move, thereby adjusting the tension degree of the conveying belt 25; a control valve 29 for controlling the operation of hydraulic cylinder 26 is also installed in a line connecting hydraulic cylinder 26 and oil line 24.
As shown in fig. 5-9, the blanking hole 34 is a rectangular through hole and is located right above the conveyor belt 25, so that the powdery material in the carriage 3 falls onto the conveyor belt 25 through the blanking hole 34, when the carriage door 32 of the carriage 3 is opened, the conveyor belt 25 is started to rotate, and then the powdery material in the carriage 3 can be unloaded, the unloading speed is far faster than that of manual unloading, the requirement of a heavy-duty vehicle with large loading capacity for safely and quickly unloading the powdery material is fully met, and the practicability is good;
