Description

Technical Field

[0001] This utility model relates to the field of mining dump truck technology, specifically to an external sprinkler device for mining dump trucks. Background Technology

[0002] Mining dump trucks are heavy-duty transport vehicles specifically designed for mines. Their core function is to transport materials such as ore and slag over short distances. They have two significant features: first, the vehicle body is robust and can adapt to the harsh environment of mines, which is rugged and dusty; second, the truck bed can be hydraulically lifted, enabling rapid and automatic unloading of materials and greatly improving the efficiency of mining operations.

[0003] Existing external sprinkler systems for mining dump trucks can only spray from fixed locations, resulting in limited spraying effectiveness and an inability to provide all-around coverage. Therefore, we propose an external sprinkler system for mining dump trucks. Utility Model Content

[0004] The purpose of this utility model is to provide an external sprinkler device for mining dump trucks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An external sprinkler system for mining dump trucks includes the dump truck body and a connecting pipe, and further includes:

[0007] A water tank is fixedly installed on the body of a mining dump truck. A fixed frame is fixedly installed on one side of the water tank. A sliding shell is slidably installed on the fixed frame. A rotating groove is opened inside the fixed frame and above the sliding shell. Two threaded rods are rotatably installed in the rotating groove. The lower ends of the two threaded rods pass through the rotating groove and the sliding shell. The two threaded rods are threadedly connected to the sliding shell.

[0008] A rotating column is rotatably mounted on a sliding shell, and a connecting pipe is fixedly installed at one end of the rotating column;

[0009] A drive assembly, located within the threaded rods, is used to drive the two threaded rods to rotate.

[0010] A power assembly, located within the sliding housing, drives the rotating column to reciprocate. A water pump delivers water from the water tank to the rotating column, where the water is sprayed out through connecting pipes and several atomizing nozzles. The drive assembly rotates two threaded rods, which, under the action of the threads, cause the sliding housing to slide, displacing the atomizing nozzles and spraying them out.

[0011] The power unit can drive the rotating column to rotate back and forth, which in turn drives the connecting pipe and several atomizing nozzles to rotate back and forth, allowing water to be sprayed out from all directions.

[0012] Preferably, the driving component includes:

[0013] A motor is fixedly mounted on a fixed frame. The motor's output shaft passes through the fixed frame and extends into a rotating slot. A worm gear is fixedly mounted on the motor's output shaft, and two worm wheels are meshed on one side of the worm gear. The two worm wheels are respectively fixedly connected to two threaded rods. A water pump delivers water from a water tank to a rotating column. The water in the rotating column is sprayed out through a connecting pipe and several atomizing nozzles. Simultaneously, the motor is started, and the motor is powered on and drives the worm gear to rotate. The worm gear drives the two meshing worm wheels to rotate, and the two worm wheels drive the two threaded rods to rotate. Under the action of the threads, the two threaded rods drive the sliding housing to slide, and the several atomizing nozzles driven by the threaded rods move up and down to spray out.

[0014] Preferably, the power assembly includes:

[0015] The power chamber is located within a sliding shell, where an electric push rod is fixedly installed. A rack is fixedly mounted on the telescopic end of the electric push rod, and a gear is meshed on one side of the rack. The lower end of the gear passes through the power chamber and is fixedly connected to a rotating column. When the electric push rod is activated, it drives the rack to slide back and forth, which in turn drives the meshing gear to rotate back and forth. The gear then drives the rotating column to rotate back and forth, which in turn drives the connecting pipe and several atomizing nozzles to rotate back and forth, allowing water to be sprayed from all directions.

[0016] Preferably, the motor's output shaft is rotatably connected to the fixed frame and the rotating slot; the worm and two worm wheels are rotatably connected to the rotating slot; the rack is slidably connected to the power cavity; and the gear is rotatably connected to the power cavity. This ensures that the motor's output shaft can rotate within the fixed frame and the rotating slot, that the worm and two worm wheels can rotate within the rotating slot, and that the gear can rotate within the power cavity.

[0017] Preferably, a storage battery is fixedly installed on the top of the fixed frame, and the storage battery is electrically connected to the motor and the electric actuator. This ensures that both the motor and the electric actuator can be powered on and operate.

[0018] Preferably, a plurality of atomizing nozzles arranged in a ring at equal intervals are fixedly installed on the connecting pipe. The plurality of atomizing nozzles can spray water evenly.

[0019] Preferably, the two worm gears are arranged in parallel. This ensures that the two threaded rods can drive the sliding housing to slide.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This mining dump truck uses an external sprinkler system. A water pump delivers water from the tank to a rotating column. The water in the rotating column is then sprayed out through a connecting pipe and several atomizing nozzles. A drive assembly drives two threaded rods to rotate. Under the action of the threads, the two threaded rods cause the sliding housing to slide, and the several atomizing nozzles driven by the threaded rods move up and down to spray water. A power assembly drives the rotating column to rotate back and forth, which in turn drives the connecting pipe and several atomizing nozzles to rotate back and forth, allowing water to be sprayed out from all directions.
