Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining equipment, and in particular relates to a coal mining machine used in an intelligent mining face system of an inclined coal seam. Background Art

[0002] Inclined coal seams mainly refer to coal seams with an angle of 30 to 45 degrees, which are prone to instability and often experience "falling over" and "biting" phenomena. One of the advantages of using an intelligent mining system is that centralized remote control can set the control console above the ground, which can reduce the number of people in the coal mine and protect personal safety. The second advantage is that visualized operations can predict the occurrence of accidents in advance and prevent them before they happen.

[0003] Chinese patent publication number CN219865000U discloses a coal mining machine system for an intelligent mining face system of an inclined coal seam. The system adopts a follower position sensor component, which can move parallel to the coal mining machine using a track. A spring-supported metal hinge plate is arranged on the top, and a cross plate is arranged on the coal mining machine. When the coal mining machine moves, the cross plate will press down the metal hinge plates one by one. The position sensor will sense the movement of the metal hinge plates, and then accurately determine the position of the coal mining machine, realize accurate feedback of the position of the coal mining machine, and transmit the information to the display screen of the chute host, providing a basis for centralized control of the coal mining system.

[0004] However, when the coal mining machine in the coal mining system is mining, it usually uses a nozzle to spray water to achieve a covering suppression of sparks and dust during the cutting process of the pick, and better reduce the potential safety hazards of mining. However, this water spraying method is mainly for dust suppression, and cannot play a good cooling role on the cutting part, which will cause the temperature of the pick to be too high, affecting the service life of the cutting part.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figure 1 to Figure 6 As shown, a coal mining machine for an intelligent mining face system for inclined coal seams in one embodiment of the utility model can realize remote operation of the coal mining machine through the intelligent mining face system, and realize intelligent mining of inclined coal seams. However, the existing coal mining machines for intelligent mining face systems for inclined coal seams generally reduce the dust generated during the coal mining process by spraying to avoid dangerous situations such as explosions caused by dense dust. This is mainly aimed at suppressing dust, making it difficult to cool the cutting part 11, thereby reducing the service life of the cutting part 11.

[0030] In order to solve the above problems, a coal mining machine for an intelligent mining face system of an inclined coal seam includes a coal mining machine body 1, and cutting parts 11 are arranged at both ends of the coal mining machine body 1, and the coal seam is mined through the cutting parts 11. A liquid storage component and a nozzle 5 matching the liquid storage component are arranged on the coal mining machine body 1, and a water pump 3 is arranged between the nozzle 5 and the liquid storage component. The spraying end of the nozzle 5 is directly facing the cutting part 11, and the nozzle 5 can extract the liquid in the liquid storage component through the water pump 3 and spray it on the cutting part 11, so as to cool the cutting part 11 and reduce the dust generated during the operation of the cutting part 11.

[0031] Specifically, the liquid storage assembly includes two water tanks 2, which are fixedly connected to both sides of the coal mining machine body 1 respectively. Water or other coolant is stored in the water tanks 2. A second connecting pipe 22 is connected between the two water tanks 2, and the second connecting pipe 22 connects the two water tanks 2.

[0032] like Figure 1 to Figure 4As shown, a first connecting pipe 21 is connected between the water tank 2 and the water pump 3, and a fourth connecting pipe 31 is connected between the water pump 3 and the nozzle 5. The coolant in the water tank 2 is transported to the water pump 3 through the first connecting pipe 21, and the water pump 3 transports the liquid to the nozzle 5 through the fourth connecting pipe 31. The nozzle 5 then sprays the coolant onto the cutting part 11, thereby cooling the cutting part 11 and reducing the dust during the operation of the cutting part 11. The cutting part 11 is well cooled, which can extend the service life of the cutting part 11. The coolant impacts the cutting part 11, disperses the coolant, and thus achieves the effect of dust reduction.

[0033] like Figure 1 to Figure 3 As shown, a fixing frame 4 is fixedly connected to the upper end surface of the coal mining machine body 1, and a mounting groove 41 is provided on the fixing frame 4, and a threaded hole 42 is provided on the side wall of the mounting groove 41. A mounting block 51 is fixedly connected to the lower end surface of the nozzle 5, and a through hole 511 matching the threaded hole 42 is provided on the mounting block 51, and the mounting block 51 can be stuck in the mounting groove 41. A fixing bolt 7 is arranged in the threaded hole 42, and the fixing bolt 7 can pass through the mounting groove 41 and the through hole 511 in sequence to fix the fixing frame 4 and the nozzle 5 together, thereby fixing the nozzle 5.

[0034] like Figure 1 to Figure 3 As shown, the mounting block 51 can rotate around the fixing bolt 7 as the axis, that is, the nozzle 5 can rotate around the fixing bolt 7 as the axis to change the spraying position of the nozzle 5. When the angle of the cutting portion 11 changes, the position of the nozzle 5 can be adjusted so that the nozzle 5 can be accurately aligned with the cutting portion 11 and coolant can be sprayed to the cutting portion 11 to achieve cooling of the cutting portion 11.

[0035] like Figure 2-3 As shown, a water-scattering structure 6 matching the nozzle 5 is rotatably connected to the mounting block 51 , and the water-scattering structure 6 can scatter the coolant sprayed from the nozzle 5 , so that the coolant contacts the dust.

[0036] Specifically, the water-spreading structure 6 includes two first connecting plates 61 rotatably connected to both sides of the mounting block 51, a second connecting plate 62 is fixedly connected between the two first connecting plates 61, a water-spreading block 63 is fixedly connected to the second connecting plate 62, and a coil spring is provided at the rotation connection between the mounting block 51 and the first connecting plate 61. When the liquid sprayed from the nozzle 5 contacts the water-spreading block 63, the cooling liquid is impacted and dispersed, and the water-spreading structure 6 is impacted by the impact force, so that the water-spreading structure 6 rotates downward for a distance, and the water-spreading structure 6 is restored to its original position through the coil spring, and is impacted by the sprayed cooling liquid again, and the cooling liquid is impacted and dispersed, and the cycle is repeated. That is, the sprayed cooling liquid is cyclically changed between the two states of columnar and granular mist, so that the cooling liquid can also play a role in reducing dust when cooling the cutting part 11.

[0037] like Figure 1 to Figure 4 As shown, a collecting plate 12 is also provided on the main body 1 of the coal mining machine, and a collecting portion 13 is provided on the collecting plate 12. The collecting plate 12 is used to collect coal, and the collecting portion 13 is used to plane the coal onto the collecting plate 12. A transport channel 14 is also provided on the main body 1 of the coal mining machine, and a conveyor belt 15 matching the transport channel 14 is installed on the main body 1 of the coal mining machine, and the height of the conveyor belt 15 matches the position of the collecting plate 12. The coal is transported to the conveyor belt 15 through the cooperation of the collecting plate 12 and the collecting portion 13.

[0038] like Figure 6 As shown, the conveyor belt 15 is mainly composed of a filter mesh layer 151 and a water absorbing layer 152, and the water absorbing layer 152 is formed by adding two filter mesh layers 151. The filter mesh layer 151 can filter the coal slag so that the coal slag is located on the upper end surface of the filter mesh layer 151, and the water absorbing layer 152 is used to absorb the coolant and recycle the coolant.

[0039] like Figure 4-5 As shown, a water collecting box 8 is fixedly connected to the lower end of the conveyor belt 15, and a water squeezing part 9 for squeezing the conveyor belt 15 is also installed on the side wall of the transport channel 14. The water squeezing part 9 squeezes the conveyor belt 15 to squeeze out the coolant attached to the coal mining machine body 1, and the coolant is collected by the water collecting box 8. A third connecting pipe 23 is connected between the water collecting box 8 and the water tank 2, and the coolant in the water collecting box 8 can be transported to the water tank 2 through the third connecting pipe 23. Thereby, the recycling of the coolant is realized, and the number of times the coolant is added in the coal mine is reduced.

[0040] Preferably, in order to ensure the cleanliness of the coolant in the water collecting box 8, a scraper can be set on one side of the conveyor belt 15, and the scraper can be used to scrape off the coal slag attached to the surface of the conveyor belt 15 to avoid the coal slag and the coolant from entering the water tank 2 together as much as possible.

[0041] When using, Figure 1 As shown, first, the cutting part 11 will dig and cut the coal seam. During the digging process of the cutting part 11, the nozzle 5 will spray out the coolant to cool the cutting part 11. The coolant impacts on the cutting part 11, so that the coolant is dispersed, and the coolant plays a role in suppressing dust. The collecting plate 12 collects the coal dug by the cutting part 11 and transports it to the conveyor belt 15 through the collecting part 13. The coal is transported together with the coolant. The conveyor belt 15 can absorb the coolant and squeeze the coolant out through the squeezing part 9, collect it through the water collecting box 8, and can be transported to the water tank 2 through the third connecting pipe 23. The coolant can be circulated, thereby increasing the endurance of the coolant spraying.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
