Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a long-range fog cover dust collector for a coal mining machine. Background Art

[0002] When in use, the existing long-range fog hood dust collector of the coal mining machine needs to be fixed on the platform steel plates at both ends of the coal mining machine through permanent magnetic suction cups. The long-range fog hood dust collector includes an injection box body and a plurality of atomizing long-range guns arranged on the injection box body. The smoke and dust generated in the coal mining process are removed by the water mist sprayed by the atomizing long-range gun.

[0003] For example, a Chinese patent with publication number CN115845533A discloses a long-range magnetized water mist dust collector for underground coal mining. The technical solution for adjusting the angle of the long-range gun atomization assembly is to use a three-stage atomization long-range gun assembly support plate, a connector I, a connector II, a connecting rod, a traction nut, a traction screw, a screw knob and a locking nut to achieve the angle adjustment of the long-range gun atomization assembly.

[0004] The disadvantage of the above scheme is that, since multiple atomizing long-range guns are arranged on the injection box body, only the angle of one atomizing long-range gun can be adjusted at a time by adopting the above scheme. Therefore, when the injection angles of multiple atomizing long-range guns need to be adjusted, they can only be adjusted one by one, and the adjustment speed is slow. Based on the above situation, it is necessary to design a coal mining machine long-range fog hood dust collector to solve the above problem. Utility Model Content

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, it is a structural schematic diagram of the prior art of the utility model, the existing injection box body 1 and the permanent magnetic suction cup 2 are an integrated fixed structure, wherein the permanent magnetic suction cup 2 is an existing structure, and its interior is composed of multiple permanent magnets. The direction of the internal permanent magnet is changed by an external driving handle to adjust the magnetic flux lines, thereby realizing magnetic adsorption and demagnetization of the platform steel plates at both ends of the coal mining machine. Since the permanent magnetic suction cup 2 is an existing structure and has nothing to do with the invention point of the utility model, it will not be elaborated here.

[0035] The main technical problem to be solved by the present invention is to synchronously adjust the angles of a plurality of atomizing long-range guns 3 on a spray box body 1, which is mainly achieved by the following technical means.

[0036] A long-range fog hood dust collector for a coal mining machine comprises a permanent magnetic suction cup 2 and an injection box body 1. A plurality of atomizing long-range guns 3 are arranged at the front end of the injection box body 1. The permanent magnetic suction cup 2 and the injection box body 1 are hingedly connected. A supporting plate 201 extending to the bottom of the injection box body 1 is integrally formed at the bottom of the permanent magnetic suction cup 2. An angle locking component for maintaining the angle between the injection box body 1 and the permanent magnetic suction cup 2 is arranged on the supporting plate 201. The permanent magnetic suction cup 2 and the injection box body 1 are hingedly connected via a hinge shaft 4 and a sleeve 5.

[0037] It needs to be further explained that Figure 2 As shown, the hinge shaft 4 can be set on the permanent magnetic suction cup 2, and the sleeve 5 is integrally formed with the spray box body 1. Of course, the hinge shaft 4 can also be set on the spray box body 1, and the sleeve 5 is set on the permanent magnetic suction cup 2, which can also achieve hinge connection. By transforming the traditional structure in which the spray box body 1 and the permanent magnetic suction cup 2 are integrated into a structure in which the spray box body and the permanent magnetic suction cup 2 are hinged, it is possible to adjust the angle between the spray box body 1 and the permanent magnetic suction cup 2 to achieve angle adjustment of multiple atomizing long-range guns 3 on the spray box body 1, and the spray box body 1 can be stably maintained at a fixed angle by setting an angle locking assembly.

[0038] In order to smoothly implement the above solution, a first embodiment of the utility model is proposed, as follows: Figure 2 and Figure 3 As shown, the angle locking assembly includes a mounting plate 6 fixed on the carrier plate 201, a latch pin 7 arranged on the mounting plate 6, and a plurality of pin holes 9 arranged on the injection box body 1 circumferentially around the axis of the hinge between the permanent magnetic chuck 2 and the injection box body 1.

[0039] A plurality of latches 7 and a plurality of pin holes 9 are provided, so that the spray box body 1 can be plugged into different pin holes 9, so that the spray box body 1 can be fixed at different positions, thereby realizing the angle adjustment of the spray box. Furthermore, a spring 8 is provided on the outer surface between the end of the latch 7 away from the spray box body 1 and the mounting plate 6, so that the latch 7 can be stabilized inside the pin hole 9.

[0040] Similarly, the present utility model proposes a second embodiment, such as Figure 4 and Figure 5 As shown, the angle of the injection box body 1 can also be locked. The angle locking assembly includes a column 10 fixed to the outer surface of the injection box body 1, an inverted U-shaped frame 11 fixed on the supporting plate 201, slide grooves 1101 on both sides of the U-shaped frame 11, a rectangular frame 13 slidingly matched with the slide grooves 1101, and a pulling bolt 12 with threads passing through the top of the U-shaped frame 11. The bottom of the pulling bolt 12 is rotatably connected to the rectangular frame 13, and the column 10 is inside the rectangular frame 13.

[0041] A lifting bolt 12, a rectangular frame 13 and a U-shaped frame 11 are provided, and when the lifting bolt 12 is rotated, the rectangular frame 13 can be driven to move up and down. The rectangular frame 13 changes the position of the spray box column body by controlling the lifting column 10, thereby adjusting the angle of the atomizing long-range gun 3 on the spray box body 1.

[0042] Furthermore, the present invention proposes a third embodiment, such as Figure 6 and Figure 7 As shown, the angle locking of the spray box body 1 is achieved, and the angle locking assembly includes a Z-shaped bracket 20 fixed on the supporting plate 201, a rocker 21 hinged at the middle of the Z-shaped bracket 20, and an extrusion bolt 22 with threads passing through the end of the Z-shaped bracket 20, one end of the rocker 21 is at the bottom of the spray box body 1, and the other end of the rocker 21 is in conflict with the bottom of the extrusion bolt 22.

[0043] By providing a Z-shaped bracket 20, a seesaw 21 and an extrusion bolt 22, pressure can be applied to one end of the seesaw 21 by turning the extrusion bolt 22 downward, so that the other end of the seesaw 21 lifts the spray box body 1, thereby achieving angle adjustment of the spray box. At the same time, a receiving groove 202 is provided on the supporting plate 201 to accommodate one end of the seesaw 21, so as to prevent the seesaw 21 from blocking the spray box body 1 from restoring a state of smooth attachment to the supporting plate 201.

[0044] Furthermore, the present invention proposes a fourth embodiment, such as Figure 8 and Fig. 9 As shown, the angle of the spray box is locked, and the angle locking assembly includes a roller 14 installed on the outer surface of the spray box body 1, a movable groove 15 opened on the supporting plate 201, a plate body 16 slidably connected to the movable groove 15 and having an inclined guide surface 19, a stabilizing plate 17 fixedly connected to the supporting plate 201 and a driving bolt 18 with threads passing through the stabilizing plate 17, and one end of the driving bolt 18 is rotatably connected to the plate body 16.

[0045] By arranging the roller 14, the plate 16, the moving groove 15 and the driving bolt 18, when the driving bolt 18 is rotated, the inclined guide surface 19 of the plate 16 can squeeze the roller 14, so that the angle of the spray box body 1 can be adjusted.

[0046] In summary, the utility model arranges the injection box body 1 and the permanent magnetic suction cup 2 in a hinged manner so that the angle between the injection box body 1 and the permanent magnetic suction cup 2 can be adjusted, and the injection box body 1 can be locked by cooperating with the angle locking component, so that the multiple atomizing long-range guns 3 on the injection box body 1 can achieve synchronous angle adjustment to meet the dust removal needs during coal mining.

[0047] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
