[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a coal mining machine onboard dust removal system, and the coal mining machine onboard dust removal system comprises:

[0043] A processing box 9, wherein a vibrating filter plate 23 is provided inside the processing box 9;

[0044] A slide rail 2 is arranged on one side of the processing box 9, and a main dust suction plate 1 and a main variable frequency dust suction fan 3 are arranged on the slide rail 2, a dust inlet pipe 5 is arranged between the air outlet end of the main variable frequency dust suction fan 3 and the processing box 9, two auxiliary dust suction plates 6 that can be slidably expanded or retracted are arranged on the slide rail 2, and auxiliary variable frequency dust suction fans 7 are arranged on the two auxiliary dust suction plates 6, and a guide hose 8 is arranged between the air outlet ends of the two auxiliary variable frequency dust suction fans 7 and the dust inlet pipe 5, the main dust suction plate 1 and the two auxiliary dust suction plates 6 are densely provided with dust suction holes 30 on the side away from the processing box 9, a dust concentration sensor 4 for sensing dust concentration is arranged on the main dust suction plate 1, and the main variable frequency dust suction fan 3 and the auxiliary variable frequency dust suction fan 7 adjust their operating conditions according to the detection results of the dust concentration sensor 4;

[0045] The dust sweeping mechanism is arranged on the processing box 9 and is used to clean the filtering surface of the filter plate 23. The coal mining machine onboard dust removal system is installed at a position where a lot of dust is generated when the coal mining machine is mining but does not affect the coal mining operation.

[0046] In this solution, the dust removal area of ​​the coal mining machine's onboard dust removal system can be adjusted by sliding the auxiliary dust suction plate 6. When the dust concentration is low, the auxiliary dust suction plate 6 is retracted and not used to save energy. When the dust concentration is high, the auxiliary dust suction plate 6 is unfolded to remove dust together with the main dust suction plate 1 to improve the dust removal efficiency. The dust concentration in the environment can be timely known through the dust concentration sensor 4, and whether to use the auxiliary dust suction plate can be adjusted according to the dust concentration, as well as whether the main variable frequency dust suction fan 3 and the auxiliary variable frequency dust suction fan 7 are working and the power can be adjusted, thereby ensuring the dust removal effect while reducing energy consumption.

[0047] Specifically, at the initial operation, the two auxiliary dust suction plates 6 are retracted. When the dust concentration value detected by the dust concentration sensor 4 is within the minimum gradient value range, the main variable frequency dust suction fan 3 is in a low power operation state. When the dust concentration value rises, the operating power of the main variable frequency dust suction fan 3 is increased to improve the dust suction efficiency. When the dust concentration value reaches the set value, the two auxiliary dust suction plates 6 slide and unfold and the auxiliary variable frequency dust suction fan 7 is started to assist the dust suction operation. The model of the dust concentration sensor 4 is ND-T103 or other models. Among them, the dust suction plate adopts the existing mature technology.

[0048] This solution uses the dust concentration sensor 4 to sense the dust concentration in real time and control the corresponding components according to the settings (the dust concentration gradient value set in the background, and the corresponding response settings are enabled when the dust concentration falls into the corresponding concentration gradient value), wherein:

[0049] When the dust concentration value is within the minimum gradient value range, the main variable frequency dust suction fan 3 is in a low power operation state to reduce energy consumption;

[0050] When the dust concentration value rises, the operating power of the main variable frequency dust suction fan 3 will be increased to improve the dust suction efficiency, and when the dust concentration value reaches a certain value, the two auxiliary dust suction plates 6 will slide and unfold and the corresponding auxiliary variable frequency dust suction fan 7 will start to assist the dust suction operation, thereby improving the dust removal efficiency and achieving fast and efficient dust removal;

[0051] When the dust concentration drops to a certain value, the two auxiliary variable frequency dust suction fans 7 are shut down, and the two auxiliary dust suction plates 6 are reset at the same time, and the dust removal effect is adaptively adjusted according to the dust concentration, ensuring sufficient and efficient dust removal while optimizing energy consumption and reducing coal mining costs.

[0052] like Figure 3 As shown, the slide rails 2 are provided on both sides of the main dust suction plate 1, and the two sides of the two auxiliary dust suction plates 6 can be slidably clamped in the two slide rails 2 respectively, which improves the sliding stability of the auxiliary dust suction plates 6.

[0053] Furthermore, each of the two slide rails 2 is provided with a rotatable threaded rod 20, the length direction of the threaded rod 20 is perpendicular to the length direction of the slide rail 2, and the two threaded rods 20 are respectively sleeved with threaded internal threaded sleeves 21, and each of the internal threaded sleeves 21 is hinged with two support rods 22, and the two support rods 22 on the same internal threaded sleeve 21 are respectively hinged to the two auxiliary dust suction plates 6 at one end away from the internal threaded sleeve 21.

[0054] The driving ends of the two threaded rods 20 are respectively provided with driving motors 19, and the driving motors 19 are installed on the corresponding slide rails 2. In this embodiment, the two threaded rods 20 are driven by the two driving motors 19 to rotate synchronously to drive the two auxiliary dust suction plates 6 to slide, unfold and reset.

[0055] like Figures 4 to 6 As shown, a boss 27 is provided on the inner wall of the processing box 9, and a plurality of limiting posts 26 are provided on the filter plate 23, each of the limiting posts 26 movably passes through the boss 27, and a limiting block 24 is provided at one end of the limiting post 26 away from the filter plate 23, and a compression spring 25 is sleeved on the column section of the limiting post 26 located between the boss 27 and the filter plate 23, and a rotatable rotating rod 12 is provided inside the processing box 9, and the rotating rod 12 is penetrated by at least one cam 11 whose side can abut against the filter plate 23. The rotating rod 12 can be driven to rotate by a motor or other means.

[0056] In this way, the rotating rod 12 rotates so that the cam 11 cyclically hits the filter plate 23 continuously, so that the filter plate 23 is in a vibrating state, thereby shaking off the dust adhering to the filtering surface of the filter plate 23. The moving range of the filter plate 23 is limited by the limit block 24.

[0057] In one embodiment, one end of the rotating rod 12 is arranged opposite to the opening of the dust inlet pipe 5 and is provided with a spiral blade 29, and the airflow of the dust inlet pipe 5 drives the spiral blade 29 and the rotating rod 12 to rotate. In this way, there is no need to separately set a driving motor for the rotating rod 12, which simplifies the structure.

[0058] Among them, the dust sweeping mechanism includes: a strip brush 28, which is arranged inside the processing box 9 and the bristles of the strip brush 28 are in contact with the filtering surface of the filter plate 23; a circular member 15, which is rotatably arranged outside the processing box 9 through a rotating shaft 14, and a square rod 18 is provided on the strip brush 28, and the square rod 18 passes through the box wall of the processing box 9 and a strip frame 16 is provided at one end of the square rod 18 located outside the processing box 9, and a column 17 adapted to the strip frame 16 is provided on the circular member 15, and the column 17 and the rotating shaft 14 are arranged parallel, and the column 17 passes through the inner side of the strip frame 16, and a transmission member 10 is provided between the rotating rod 12 and the rotating shaft 14.

[0059] The transmission member 10 includes a synchronous transmission structure composed of a plurality of transmission wheels, transmission chains or transmission belts, which belongs to the existing mature technology and will not be described in detail here.

[0060] Under the transmission action of the transmission member 10, the rotation of the rotating rod 12 drives the circular member 15 to rotate, and the rotation of the circular member 15 causes the strip brush 28 to move back and forth, that is, the bristles of the strip brush 28 are in contact with the filtering surface of the filter plate 23 and brush back and forth, brushing away the dust adhering to the filtering surface of the filter plate 23, preventing the filter plate 23 from being blocked, and ensuring smooth airflow.

[0061] Among them, a dust hopper 13 is provided in the processing box 9 for collecting dust. The dust hopper 13 and the processing box 9 are in a pull-out fit (similar to the form of a drawer), and the dust filtered by the filter plate 23 is concentrated in the dust hopper 13 for subsequent cleaning.

[0062] The conveying hose 8 is a stainless steel hose, which can ensure its strength and durability.

[0063] The above-mentioned embodiment of the present invention provides an onboard dust removal system for a coal mining machine, which senses the dust concentration in real time through a dust concentration sensor 4 and controls the corresponding components according to the settings. When the dust concentration value is within the minimum gradient value range, the main variable frequency dust suction fan 3 is in a low-power operation state to reduce energy consumption. When the dust concentration value rises, the operating power of the main variable frequency dust suction fan 3 is increased to improve the dust suction efficiency. When the dust concentration value reaches a certain value, the two auxiliary dust suction plates 6 slide and unfold and the corresponding auxiliary variable frequency dust suction fans 7 are started to assist in dust suction operations, thereby improving the dust removal efficiency and achieving fast and efficient dust removal. When the dust concentration is reduced to a certain value, the two auxiliary variable frequency dust suction fans 7 are shut down, and the two auxiliary dust suction plates 6 are reset at the same time. The dust removal effect is adaptively adjusted according to the dust concentration to ensure sufficient and efficient dust removal while optimizing energy consumption and reducing coal mining costs.

For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0065] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being only exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0067] In the description of this scheme, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing this scheme and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the scope of protection of this scheme; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0068] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0069] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this scheme.
