Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, and in particular to a dust removal device for mining hydraulic supports. Background Technology

[0002] Hydraulic supports are structures used to control mine pressure at coal mining faces. The mine pressure acts on the hydraulic supports as an external load. After use, the hydraulic supports undergo end-wall cleaning to remove dust from the support end walls. This can be achieved by using an air pump and nozzles to blow air across the support end walls and remove dust. This dust removal device is specifically designed for cleaning the dust from the support end walls.

[0003] Hydraulic supports are large in size, and it takes a long time to clean the dust on the end walls of the hydraulic supports. At the same time, the pump body is usually connected to the air nozzle through a pipeline. When holding the air nozzle, it is very time-consuming and laborious to clean the dust. Although the air nozzle and pump body are integrated, there is no need to hold the air nozzle. However, it is still difficult to clean the dust in the dead corners of the end walls of the support. It is not convenient to use and the cleaning effect is also poor. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for mining hydraulic supports.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust removal device for a mining hydraulic support includes a base, a fan mounted on the upper end of the base, rectangular side plates mounted on both sides of the base, and a spray hole for discharging airflow on the side wall of the side plate away from the base. An inner cavity is formed on the side wall of the base near the fan. A plate cavity for guiding airflow is formed inside the side plate. A take-up roller is mounted on the bottom end wall of the base near the side plate. An air pipe for connecting the inner cavity and the plate cavity is wound around the outside of the take-up roller. A sliding groove is formed at the bottom of the base. A sliding strip is installed inside the base. An insertion port is formed on the end wall of one end of the sliding strip. A pin connected to the side plate is installed in the insertion port.

[0007] Preferably, there are two side plates, and the side plates and the pins are fixedly connected.

[0008] Preferably, the side plate is engaged with the socket by a pin, so that the side plate and the slide bar are connected together.

[0009] Preferably, the nozzle and the plate cavity are connected, and the inner cavity is also connected to the fan.

[0010] Preferably, there are two take-up rollers, and the take-up rollers are rotatably connected to the base.

[0011] Preferably, the grooves and slide bars are symmetrically distributed about the center of the base.

[0012] This utility model has at least the following beneficial effects:

[0013] The design of the sliding groove and sliding strip, along with the pin and socket, allows the side plate to be detachably assembled onto the sliding strip. When removing the side plate, the side plate can be held in hand to clean the end wall of the support. When assembling, the hands are freed, and the side plate can be placed on the side of the support to blow away and clean the dust from the end wall of the support. Moreover, the bottom of the pin on the side plate is conical, which is used to insert into the soil or other structures, making it convenient for the side plate to be inserted into the side of the support for cleaning.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a dust removal device for mining hydraulic supports:

[0022] like Figure 1-4As shown, a dust removal device for a mining hydraulic support includes a base 1, a fan 2 mounted on the upper end of the base 1, rectangular side plates 3 mounted on both sides of the base 1, and a nozzle 4 for discharging airflow on the end wall of the side plate 3 away from the base 1. There are two side plates 3, and the side plates 3 are fixedly connected to the pins 12. The side plates 3 are engaged with the sockets 11 by the pins 12, so that the side plates 3 and the slide bars 10 are connected. After the pins 12 are inserted into the sockets 11, the side plates 3 and the slide bars 10 are connected. At this time, it is convenient to place the side plates 3 on the slide bars 10 for use, which saves effort. The sliding grooves 9 and the slide bars 10 are symmetrically distributed about the center of the base 1, and the slide bars 10 can slide and move laterally along the sliding grooves 9 to change the position of the slide bars 10 and the side plates 3, which is convenient. When it is necessary to clean the dust in the dead corner of the end wall of the mining hydraulic support, the side plates 3 can be removed and the side plates 3 can be held by hand to clean the dust on the end wall of the support, which is more flexible and more applicable.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, an inner cavity 7 is provided on the side wall of the base 1 near the fan 2. A plate cavity 8 for guiding airflow is provided inside the side plate 3. A take-up roller 5 is installed on the bottom of the base 1 near the side plate 3. An air pipe 6 for connecting the inner cavity 7 and the plate cavity 8 is wound around the outside of the take-up roller 5. A sliding groove 9 is provided at the bottom of the base 1. A slide bar 10 is installed inside the base 1. An insertion port 11 is provided on the end wall of one end of the slide bar 10. A pin 12 connected to the side plate 3 is installed in the insertion port 11. The spray hole 4 and the plate cavity 8 are connected. At the same time, the inner cavity 7 is connected to the fan 2. There are two take-up rollers 5, and the take-up rollers 5 are rotatably connected to the base 1. When the fan 2 runs, the air is guided along the inner cavity 7 into the air pipe 6, then along the plate cavity 8, and finally sprayed out along the spray hole 4 to blow and clean the side area of ​​the side plate 3 and blow away the dust on the end wall of the support.

[0024] Working principle:

[0025] When the blower 2 is running, the airflow is introduced along the inner cavity 7, then input into the plate cavity 8 through the air pipe 6, and finally sprayed out from the nozzle 4 to blow and clean the end wall of the mining hydraulic support, removing dust and impurities from the end wall of the support.

[0026] The base 1 has a sliding groove 9 for sliding connection of the slide bar 10, allowing the slide bar 10 to move and be adjustable. The slide bar 10 is also provided with a socket 11 for inserting the pin 12, so that the side plate 3 can be detachably assembled onto the slide bar 10. When removing the side plate 3, the side plate 3 can be held to clean the end wall of the bracket. When assembling, the hands are freed. The side plate 3 can be placed on the end side of the bracket to blow away and clean the dust on the end wall of the bracket. Moreover, the bottom of the pin 12 at the bottom of the side plate 3 is conical, which is used to insert into the soil and other structures, making it convenient for the side plate 3 to be inserted into the end side of the bracket for cleaning.

[0027] Finally, the take-up roller 5 is used to rotate the take-up and release air pipe 6, which makes it convenient for the air pipe 6 to extend after the side plate 3 is removed, and to move the side plate 3 away. It also makes it convenient for the air pipe 6 to be rotated and rolled up by the take-up roller 5, thus improving the neatness of the entire structure.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
