Description

Technical Field

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

[0002] With the gradual increase in the level of mechanization and the continuous increase in mining intensity in underground coal mines, the dust problem generated during coal mining is becoming increasingly serious. As the place with the largest dust generation, the fully mechanized mining face not only affects the normal production of the mine, but also seriously threatens the life safety of workers. Long-term inhalation of dust can easily lead to pneumoconiosis and other occupational diseases. At the same time, high concentrations of dust also pose an explosion hazard, affecting the safe production of coal mines.

[0003] Traditional spray dust suppression devices suffer from low spray pressure, resulting in unsatisfactory dust removal effects. They also suffer from low automation, lack dust monitoring capabilities, and cannot adjust spray patterns in real time based on dust concentration. Furthermore, they have low settling efficiency for respirable dust and struggle to effectively capture fine, inhalable dust particles. While existing coal mining machines can reduce dust concentration in the working area to some extent by spraying water mist, thus improving the working environment to a certain degree, their excessively high spray flow rate not only consumes a lot of water but also affects coal quality. Additionally, the nozzles have poor atomization and are prone to clogging, failing to meet user needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spray dust removal device for a coal mining machine, aiming to improve the problems of high water consumption and poor dust removal effect in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spray dust removal device for a coal mining machine, comprising a support plate, a funnel fixedly connected to the top of the support plate, a dust removal mechanism fixedly connected to the top of the funnel, and a pushing mechanism fixedly connected to the bottom of the support plate. The pushing mechanism is used to push out dust for easy collection. The dust removal mechanism includes a wind duct, the bottom of which is fixedly connected to the top of the support plate. A support assembly is fixedly connected to the top of the wind duct, a motor is fixedly connected to the top of the support assembly, an impeller is fixedly connected to the output end of the motor, a wind guide assembly is fixedly connected to the bottom of the impeller, and an air outlet assembly is fixedly connected to the rear side of the wind duct.

A second motor is fixedly connected to the bottom of the loading box, and a gear is fixedly connected to the output end of the second motor. A rack is meshed with the outer wall of the gear. A sliding assembly is fixedly connected to the bottom of the loading box, and an outer frame assembly is rotatably connected to the bottom of the gear.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the coal mining machine is working, dust enters the outer shell through the opening of the receiving interface. The motor at the top of the outer shell is started, which causes the impeller at the bottom to rotate, swirling and absorbing the incoming dust, which falls to the bottom. The guide plate can assist in the rotation and separation. Large dust particles fall to the bottom through the opening of the funnel, and the gas escapes through the pipe, thus achieving the dust removal effect.

The fixing plate 6 is used to further reinforce and stabilize the entire structure, ensuring that the connection between the components is firm and reliable.

[0040] Working principle: When the coal mining machine is working, dust enters the outer casing 2021 through the opening of the receiving interface 5. The motor 203 at the top of the outer casing 2021 is started, which makes the impeller 204 at the bottom rotate, swirling and absorbing the incoming dust, which falls to the bottom. The guide plate 2052 can assist in the rotation and separation. Large dust particles fall to the bottom through the opening of the funnel 4, and the gas escapes through the pipe 2061, thus achieving the dust removal effect.

[0041] When dust accumulates at the bottom, the motor 303 inside the loading box 301 is activated, causing the gear 304 at the output end to rotate. The rack 305, which is meshed with the outer wall, moves forward. The sliding column 3061 at the bottom of the loading box 301 slides on the inner wall of the rectangular groove 3062, making the pushing process smoother and more stable. This structure provides convenience for users and reduces their workload.
