[0037] In the related art, the observation mirror of the feeder has the technical problem of inconvenient cleaning.The embodiments of the application provide a window mechanism and a feeder, which can at least solve the technical problem of inconvenient cleaning of the observation mirror of the feeder to a certain extent.

[0038] As shown in Figure 1 The window mechanism 100 includes an observation mirror 110, a rotating rod 120 and a scraping arm 130.The middle part of the observation mirror 110 is provided with a mounting hole 110b, and the observation mirror 110 is used to be mounted on the shell of the feeder.The rotating rod 120 includes a holding section 121 and a connecting section 122 connected with the holding section 121, the connecting section 122 penetrates through the mounting hole 110b and is rotationally connected with the inner wall of the mounting hole 110b, and the holding section 121 is arranged at an angle with the connecting section 122;The scraping arm 130 is connected with the side of the connecting section 123 away from the holding section 121, and is in contact with the surface 110a to be cleaned of the observation mirror 110, and the scraping arm 130 and the holding section 121 are located on the two sides of the observation mirror 110 respectively.

[0039] The observation mirror 110 is transparent, which can be made of glass, plastic or the like. The mounting hole 110b on the observation mirror 110 is used to avoid the rotating rod 120. In use, the observation mirror 110 is mounted in the mounting port of the shell, the scraping arm 130 is located inside the shell, the holding section 121 is located outside the shell, and the inner surface of the observation mirror 110 is the surface to be cleaned 110a. The connecting section 122 of the rotating rod 120 is rotationally connected with the observation mirror 110. The operator stands outside the feeder and holds the holding section 121 to rotate the holding section 121, thereby rotating the rotating rod 120 as a whole, driving the scraping arm 130 on the connecting section 122 to rotate, so that the scraping arm 130 sweeps each area of the surface to be cleaned 110a of the observation mirror 110, and cleans the condensed water vapor, coal dust and other dirt on the surface to be cleaned 110a of the observation mirror 110. The holding section 121 and the connecting section 122 are arranged at an angle, which can be a right angle, an acute angle or an obtuse angle. The angle arrangement of the holding section 121 and the connecting section 122 can facilitate the rotation of the rotating rod 120 by the user.

[0040] In this way, the operator can clean the surface to be cleaned 110a of the observation mirror 110 in real time by rotating the holding section 121 without shutting down the medium-speed mill system, which simplifies the cleaning process of the observation mirror 110, improves the cleaning efficiency, facilitates the cleaning of the observation mirror, avoids energy waste caused by frequent start and stop of the equipment, and ensures orderly production.

[0041] In some embodiments, the connecting section 122 and the holding section 121 are arranged vertically.

[0042] The surface to be cleaned 110a of the observation mirror 110 often adsorbs coal dust due to condensation of water vapor. After the water vapor evaporates, the coal dust is firmly attached, increasing the difficulty of cleaning by the scraping arm 130. At the same time, if a large amount of particulate matter such as coal dust is attached, the scraping arm 130 may move these particles on the surface of the observation mirror 110 during brushing, causing scratches and affecting the clarity of observation. Therefore, in some embodiments, the holding section 121 has a liquid inlet 121a, the connecting section 122 has a first liquid outlet 122a, the first liquid outlet 122a is arranged towards the surface to be cleaned 110a, and the liquid inlet 121a and the first liquid outlet 122a are communicated through a flow channel formed in the holding section 121 and the connecting section 122. In this way, the cleaning water and detergent for cleaning the observation mirror 110 can be injected through the first liquid outlet 122a and sprayed on the surface to be cleaned 110a of the observation mirror 110. The liquid will effectively flush most of the particulate matter and soften stubborn dirt. Subsequently, combined with the scraping action of the scraping arm 130, stubborn stains on the surface to be cleaned 110a can be removed more efficiently, improving the cleaning efficiency of the observation mirror 110 and preventing the observation mirror 110 from being scratched by coal dust and other particulate matter to some extent.

[0043] In some embodiments, a plurality of first liquid outlets 122a are arranged on the connecting section 122 at intervals along the circumference of the connecting section 122. The plurality of first liquid outlets 122a are arranged around the circumference of the second connecting member 180, which helps to ensure that the cleaning liquid can fully cover the surface 110a of the viewing mirror 110 to be cleaned, thereby further improving the cleaning efficiency and effect of the surface 110a of the viewing mirror 110 to be cleaned.

[0044] Coal dust and other impurities are likely to deposit on the scraper arm 130. With the passage of time, the accumulated thickness of the coal dust on the scraper arm 130 gradually increases, thereby blocking the observation line of sight of the operator. In addition, when too much coal dust is attached to the scraper arm 130, the coal dust may fall off and re-attach to the surface 110a of the viewing mirror 110 to be cleaned during the sweeping process, which not only affects the clarity of observation but also reduces the cleaning efficiency. Therefore, in some embodiments, the connecting section 122 further has a second liquid outlet 122b in communication with the flow channel, and the second liquid outlet 122b is arranged towards the scraper arm 130. In this way, clean water, detergent, and the like can be injected through the first liquid outlet 122a and sprayed on the scraper arm 130 through the second liquid outlet 122b to flush the accumulated coal dust and other impurities on the scraper arm 130, thereby avoiding the blocking of the observation line of sight due to the coal dust on the scraper arm 130, preventing the re-attachment of impurities to the surface 110a of the viewing mirror 110 to be cleaned, and improving the cleaning efficiency.

[0045] In some embodiments, a plurality of second liquid outlets 122b are arranged, and the plurality of second liquid outlets 122b are all arranged towards the scraper arm 130. The arrangement of the plurality of second liquid outlets 122b helps to flush each part of the scraper arm 130, effectively removing the coal dust, dust, and other impurities attached to the scraper arm 130, thereby improving the cleaning efficiency and cleanliness of the scraper arm 130.

[0046] In some embodiments, the window mechanism 100 further includes a liquid storage tank 140, a connecting pipe 150, and a water pump 160. The liquid storage tank 140 is mounted on the holding section 121, and the liquid storage tank 140 has a liquid storage cavity 140a. The connecting pipe 150 is in communication with the liquid storage cavity 140a and the liquid inlet 121a. The water pump 160 is mounted on the connecting pipe 150. The liquid storage cavity 140a of the liquid storage tank 140 is used to store clean water, detergent, and the like. The connecting pipe 150 communicates the liquid storage cavity 140a and the liquid inlet 121a. Under the action of the water pump 160, the liquid in the liquid storage cavity 140a is guided through the connecting pipe 150 and the flow channel, and finally sprayed out from the first liquid outlet 122a and the second liquid outlet 122b. The arrangement of the liquid storage tank 140, the connecting pipe 150, and the water pump 160 further facilitates the use of the window mechanism 100.

[0047] The liquid storage tank 140 can be fixedly connected to the holding section 121, and the water pump 160 can also be fixedly connected to the holding section 121.

[0048] In some embodiments, the wiper arm 130 comprises a wiper blade 132 and a wiper blade fixing member 131, the wiper blade fixing member 131 is connected to the connecting segment 122. The wiper blade 132 is connected to the wiper blade fixing member 131 and is in contact with the surface 110a to be cleaned. The wiper blade fixing member 131 is connected to the connecting segment 122, the second connecting member 180 rotates to drive the wiper blade fixing member 131 to rotate, thereby driving the wiper blade 132 on the wiper blade fixing member 131 to rotate, so that the wiper blade 132 sweeps each area of the observation mirror 110 to clean the observation mirror 110. The wiper blade 132 can be made of silica gel material, which not only has good flexibility and wear resistance, can tightly fit the surface 110a to be cleaned of the observation mirror 110, effectively remove stains, but also will not scratch the observation mirror 110, which helps to prolong the service life of the observation mirror 110.

[0049] The structure of the wiper blade fixing member 131 is various, which is not limited in the present application. In some embodiments, the wiper blade fixing member 131 is rectangular, and the wiper blade 132 is connected to the wiper blade fixing member 131 by bolts and nuts.

[0050] In some embodiments, the wiper blade fixing member 131 is detachably connected to the connecting segment 122. When the wiper blade 132 or the wiper blade fixing member 131 is damaged due to long-term use, the operator can conveniently detach it and replace or repair it without replacing the entire window mechanism 100, which helps to reduce the maintenance cost of the window mechanism 100. The detachable connection between the wiper blade fixing member 131 and the connecting segment 122 can be various, such as adhesion, clamping, threaded connection, etc.

[0051] In some embodiments, a bearing is arranged between the connecting segment 122 and the inner wall of the mounting through hole 110b, the bearing is sleeved on the outside of the connecting segment 122 and is in interference fit with the connecting segment 122, the bearing is adhered to the inner wall of the mounting through hole 110b, thereby realizing the rotary connection between the connecting segment 122 and the inner wall of the mounting through hole 110b.

[0052] In some embodiments, the window mechanism 100 further comprises a first connecting piece 170, a second connecting piece 180 and a plurality of sealing rings 190. The first connecting piece 170 and the second connecting piece 180 are both threadedly connected to the connecting section 122 and are respectively located on two sides of the viewing mirror 110; the plurality of sealing rings 190 are all sleeved outside the second connecting piece 180 and are respectively located between the first connecting piece 170 and the viewing mirror 110 and between the second connecting piece 180 and the viewing mirror 110. After the first connecting piece 170 and the second connecting piece 180 are tightened, some of the sealing rings 190 are clamped between the first connecting piece 170 and the viewing mirror 110 and the other sealing rings 190 are clamped between the second connecting piece 180 and the viewing mirror 110, so that the sealing rings 190 can seal the gap between the first connecting piece 170 and the viewing mirror 110 and the gap between the second connecting piece 180 and the viewing mirror 110 to prevent coal dust and the like from escaping through the gaps. It should be noted that the first connecting piece 170 and the second connecting piece 180 are tightened to a degree that the sealing rings 190 can play a sealing effect, and over-tightening is avoided to cause the rotating rod 120 to be unable to rotate.

[0053] In some embodiments, the first connecting piece 170 and the second connecting piece 180 are both nuts, and two sealing rings 190 are provided, one of which is arranged between the first connecting piece 170 and the viewing mirror 110 and the other of which is arranged between the second connecting piece 180 and the viewing mirror 110.
