DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific embodiments.

[0023] As Figures 1 to 6 shown, the present invention provides:

[0024] A device for cleaning the remaining coal in the carriage of a coal transport vehicle, comprising a mounting seat 1. Symmetrical conversion boxes 2 are arranged at the top of the mounting seat 1. One side of each of the two conversion boxes 2 close to each other is communicated with a three-way pipe 3 through a pipeline. One side of each of the two conversion boxes 2 away from each other is communicated with a water outlet pipe 4. The other end of the water outlet pipe 4 extends to the bottom of the mounting seat 1 and is provided with a spray head 7. Impellers 10 are rotatably arranged inside each of the two conversion boxes 2. A rotating rod 8 is rotatably arranged at the bottom of the impeller 10. One end of the rotating rod 8 extends to the bottom of the mounting seat 1 and is provided with a cleaning brush 9.

[0025] Connect the mounting seat 1 to a crane, and then use the three-way pipe 3 to communicate with an external water pump. When it is necessary to clean the remaining coal on the carriage, the mounting seat 1 can be placed on the carriage by using the crane to drive the mounting seat 1 to move. First, the remaining coal on the carriage can be cleaned through the adjusting frame 6 and the extension plate 5. At the same time, start the water pump, and the water pump transports the external water source to the inside of the spray head 7. After the external water source passes through the conversion box 2, it will drive the impeller 10 to rotate, further driving the rotating rod 8 and the cleaning brush 9 at the bottom of the impeller 10 to rotate. The cleaning brush 9 can be used to clean some missed soot. During the cleaning process, the water sprayed by the spray head 7 is used to reduce the dust generated during the working process, effectively preventing the coal dust from rising and spreading into the air. This can not only avoid air pollution but also protect the physical and mental health of the staff.

[0026] As Figure 4 and Figure 6 shown, an adjusting frame 6 is movably arranged on the side wall of the mounting seat 1, and extension plates 5 are movably arranged on both sides of the adjusting frame 6.

[0027] By using an extension plate 5 with adjustable length, the operator can flexibly and effectively clean the remaining coal on various carriages of different sizes. The design of this extension plate 5 enables it to be appropriately telescoped and adjusted according to the specific size of the carriage, thus ensuring the efficiency and convenience of the cleaning operation. Whether it is a large truck or a small transport vehicle, the extension plate 5 can provide sufficient coverage to ensure that the remaining coal in the carriage is completely removed, thereby improving the efficiency of coal transportation and the utilization rate of the carriage.

[0028] As Figure 4 shown, racks 11 are arranged on one side of each of the two extension plates 5 close to each other, a driving rod 12 is rotatably arranged inside the adjusting frame 6, and a gear 13 meshed with the rack 11 is arranged on the outside of the driving rod 12.

[0029] Through the rotational movement of the driving rod 12, the gear 13 can be driven to start rotating. As the gear 13 rotates, its precise cooperation with the rack 11 will be converted into a linear motion. This linear motion then pushes the two extension plates 5 to expand outward along a predetermined trajectory.

[0030] As Figure 5 shown, one end of the driving rod 12 extends to the outside of the adjusting frame 6, and a rotating block 17 is arranged on the top of the driving rod 12.

[0031] By using the rotating block 17, the staff can operate and drive the driving rod 12 more conveniently, making it rotate easily.

[0032] As Figure 5 shown, a sliding block 14 is slidably arranged on the outside of the driving rod 12, symmetric positioning rods 16 are arranged at the bottom of the sliding block 14, a plurality of positioning holes adapted to the positioning rods 16 are opened at the top of the adjusting frame 6, a spring 15 is sleeved on the outside of the driving rod 12, one end of the spring 15 is connected to the top of the sliding block 14, and the other end of the spring 15 is connected to the bottom of the rotating block 17.

[0033] By pulling up the sliding block 14, the positioning rod 16 at the bottom of the sliding block 14 is separated from the positioning hole at the top of the adjusting frame 6. At this time, the driving rod 12 can be rotated. During the rotation process, observe the length of the extension plate 5 until it extends to the appropriate length. Once the required length is reached, the sliding block 14 can be released. Under the elastic force of the spring 15, the sliding block 14 will quickly move downward, driving the positioning rod 16 to insert into the corresponding jack. This design effectively prevents the driving rod 12 from rotating during operation, ensuring the stable operation and precise control of the equipment.

[0034] As Figure 6 shown, baffles 18 are arranged on one side of the two extension plates 5 close to each other, and a rectangular groove for the movement of the baffles 18 is opened inside the adjusting frame 6.

[0035] By arranging the baffle 18 on one side of the carriage, the remaining coal in the carriage can be effectively cleaned. It can ensure that during the cleaning process, the excess coal will not scatter everywhere, thus keeping the inside of the carriage clean.

[0036] The above embodiments only represent one or several implementation manners of the device for cleaning the remaining coal in the carriage of the utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the appended claims.
