Description
Technical Field
[0001] This utility model relates to the field of muck removal machine technology, and in particular to a muck removal device used in coal mining. Background Technology
[0002] The prior art discloses a fully automatic slag remover (application number: CN201910165712.1), which includes a control box and a slag remover robotic arm. The top of the control box is provided with a horizontal rotating table, and the slag remover robotic arm is movably installed inside the horizontal rotating table. A lifting motor is provided on the side wall of the horizontal rotating table, and the top of the lifting motor is connected to the slag remover robotic arm. One end of the slag remover robotic arm is provided with a movable telescopic chain, and the other end of the slag remover robotic arm is provided with a slag remover handle.
[0003] Existing technology mainly uses the extension, retraction, and rotation of a robotic arm to push a scraper plate, which then pushes the scrap material towards the base to perform the scraping operation. The scraper plate and robotic arm are fixedly connected. During scraping, to prevent the scrap material from interfering with the extension of the robotic arm, the robotic arm needs to be raised so that the scraper plate is above the scrap material. During the retraction phase, the robotic arm is lowered so that the scraper plate is submerged below the material pile to complete the scraping. Therefore, raising the robotic arm during the extension phase is only to prevent interference from the material pile. This process has room for optimization. If the scraper plate and robotic arm are rotated, the material pile can push the scraper plate towards the base when the robotic arm extends, and the scraper plate can be limited during the retraction phase. This optimizes the scraping process, reduces unnecessary work, and thus improves scraping efficiency.
[0004] Therefore, we propose a slag removal device for coal mining. Utility Model Content
[0005] The present invention mainly solves the technical problem of repeatedly raising the boom during the above-mentioned slag removal process, and provides a slag removal device for coal mining.

[0007] In a preferred embodiment of this utility model, the mounting plate forms a U-shaped rod structure, and the two side walls of the slag removal plate are rotatably connected to the two opposite inner side walls of the mounting plate.
[0008] In a preferred embodiment of this utility model, the slag removal assembly further includes a sliding channel, in which the limiting body slides and restricts the slag removal plate from rotating in the direction of the boom output shaft.
[0009] In a preferred embodiment of this utility model, the limiting body is a rectangular block, and the sliding channel forms a groove that fits the limiting body.
[0010] In a preferred embodiment of the present invention, the slag removal assembly further includes a thrust member, which is locked to a limiting body by bolts, and the thrust member is engaged with the mounting plate to restrict the sliding of the limiting body.
[0011] In a preferred embodiment of the present invention, the slag removal assembly further includes anti-slip protrusions, which are fixedly connected to the thrust portion.

[0014] Beneficial effects
[0015] This utility model provides a slag removal device for coal mine mining. It has the following beneficial effects:
[0016] 1. This coal mine slag removal equipment features a rotatable slag removal plate with a limiting body that restricts its movement. When the boom output shaft extends and pushes the mounting plate and slag removal plate away from the base, the slag removal plate is pushed by the slag and rotates towards the base. When the boom output shaft retracts, the limiting body abuts against the slag removal plate and restricts its rotation, allowing the slag removal plate to push the slag towards the base, thus achieving slag removal. The rotatable slag removal plate eliminates the need to lift the boom output shaft and lower it when the boom extends, reducing interference from the slag on the slag removal plate when the boom output shaft extends, making it more suitable for reciprocating slag removal operations.
[0017] 2. This coal mine slag removal equipment uses a limit body that slides within a sliding channel to push a thrust member into the channel. Bolts are then used to lock the thrust member and the limit body in place. Anti-slip protrusions engage with corresponding grooves to lock the limit body in place. The position of the limit body can be adjusted within a certain range, allowing the slag removal plate to maintain an obtuse or acute angle with the ground during the boom output shaft retraction phase. This enables the slag removal plate to perform various postures during slag removal, such as leveling slag or hooking slag, thus expanding its functionality and enhancing its practicality.
[0018] 3. This coal mine slag removal equipment, by passing bolts through the through holes at the extension of the slag removal plate and connecting them with the threaded holes on the wall of the slag removal plate, can form a hard connection between the slag removal plate and the limiting body, so that the slag removal plate can remove slag in a way that does not flip over, further improving the slag removal posture and usage of the slag removal plate, and further enhancing its functionality.

[0025] A type of coal mine uses slag removal equipment, such as Figure 1 and Figure 2As shown, the device includes a base 10 and a large arm 11 movably mounted on the top of the base 10. The large arm 11 includes an outer shell, with a first output shaft rotatably connected to the end of the outer shell. The first output shaft is hollow inside, and a second output shaft is slidably connected inside the cavity of the first output shaft. Push cylinders are installed on the top surface of the shell and the top of the first output shaft. The push cylinders push the first output shaft to rotate and the second output shaft to slide. A connecting seat is provided on the top surface of the base 10, and the connecting seat is rotatably connected to the base 10. The shell of the large arm is fixedly mounted on the top of the connecting seat. The connecting seat is circular, and teeth are provided on the circumferential surface of the connection. A drive motor is installed on the top surface of the base 10, and a gear is fixedly mounted on the output shaft of the drive motor. The gear meshes with the teeth of the connecting seat, and the connecting seat drives the large arm 11 to rotate. In conjunction with the extension, retraction, and rotation of the large arm 11, multi-angle slag removal is achieved.
[0026] like Figure 2 , Figure 3 and Figure 4 as well as Figure 5 As shown, the output end of the boom 11 is equipped with a slag-removing assembly, which includes a mounting plate 20, a slag-removing plate 21, and a limiting body 23. The mounting plate 20 is fixedly connected to the output shaft of the boom 11, and the slag-removing plate 21 is rotatably connected to the mounting plate 20. The limiting body 23 can slide along the mounting plate 20 and restrict the slag-removing plate 21 from rotating. The mounting plate 20 forms a U-shaped rod structure. The two side walls of the slag-removing plate 21 are rotatably connected to the opposite inner side walls of the mounting plate 20. The slag-removing assembly also includes a sliding channel 22. The limiting body 23 slides within the sliding channel 22 and restricts the slag-removing plate 21 from rotating in the direction of the boom 11's output shaft. The limiting body 23 is a rectangular block, and the sliding channel 22 forms a slot adapted to the limiting body 23. In this design, the slag-removing plate 21 is... Fixedly installed at the end of the second output shaft, a flip-up slag-removing plate 21 is provided, along with a limiting body 23 that limits the slag-removing plate 21. When the output shaft of the boom 11 extends and pushes the mounting plate 20 and the slag-removing plate 21 away from the base 10, the slag-removing plate 21 will flip towards the base 10 due to the squeezing and pushing of the slag. When the output shaft of the boom 11 retracts, the limiting body 23 abuts against the slag-removing plate 21 and restricts the flip-up of the slag-removing plate 21. Thus, the slag-removing plate 21 can push the slag towards the base 10 to achieve slag removal. The flip-up slag-removing plate 21 means that when the boom 11 extends, there is no need to lift the output shaft of the boom 11 and then lower it. This reduces the interference of the slag on the movement of the slag-removing plate 21 when the output shaft of the boom 11 extends, making it more suitable for reciprocating slag removal operations.
[0027] like Figure 4 and Figure 5As shown, the slag removal assembly also includes a thrust portion 24, which is locked to the limiting body 23 by bolts. The thrust portion 24 is engaged with the mounting plate 20 and restricts the sliding of the limiting body 23. The slag removal assembly also includes anti-slip protrusions 25, which are fixedly connected to the thrust portion 24. The top surface of the sliding channel 22 has several grooves adapted to the thrust portion 24, and the anti-slip protrusions 25 can be engaged into different grooves. The thrust portion 24 forms a block structure adapted to the sliding channel 22. The wall of the thrust portion 24 has a through hole, and the side wall of the limiting body 23 has a threaded hole. Bolts pass through the through holes and are threaded to lock the thrust portion 24 and the limiting body 23. Multiple grooves on the surface are linearly distributed. The anti-slip protrusions 25 cooperate with the grooves. By pushing the limiting body 23 to slide in the sliding channel 22, the thrust part 24 is pushed into the sliding channel 22. The thrust part 24 and the limiting body 23 are locked with bolts. The anti-slip protrusions 25 are inserted into the corresponding grooves to lock the position of the limiting body 23. The position of the limiting body 23 can be adjusted within a certain range, so that during the recovery stage of the output shaft of the boom 11, the slag removal plate 21 can form an obtuse or acute angle with the ground. Thus, the slag removal plate 21 can have multiple postures when removing slag, which can be used to level slag or hook up slag. The functionality is expanded and the practicality is enhanced.
[0028] like Figure 4 and Figure 5 As shown, the length of the thrust portion 24 is greater than the width of the limiting body 23. The thrust portion 24 extends to the side of the limiting body 23. Another through hole is provided on the wall surface of the thrust portion 24, and another threaded hole is provided on the wall surface of the slag-scraping plate 21. Another bolt is provided in the through hole and connected to the threaded hole of the slag-scraping plate 21. By passing the bolt through the through hole at the extension of the slag-scraping plate 21 and connecting it to the threaded hole on the wall surface of the slag-scraping plate 21, a hard connection can be formed between the slag-scraping plate 21 and the limiting body 23. The slag-scraping plate 21 can scrape slag in a way that does not flip over, further improving the slag-scraping posture and usage of the slag-scraping plate 21, and further enhancing its functionality.
[0029] It should be further explained that the top of the thrust portion 24 is provided with an anti-slip protrusion 25, which is cylindrical and integrally formed with the thrust portion 24. The height of the limiting body 23 is greater than the height of the sliding channel 22. The end of the thrust portion 24 away from the limiting body 23 is provided with an integrally formed baffle that extends to one side of the mounting plate 20. The baffle and the limiting body 23 clamp the thrust portion 24 to prevent it from falling off within the sliding channel 22. For details, please refer to [reference needed]. Figure 4 and Figure 5 As shown, the limiting body 23 and the thrust part 24 are locked together, thus ensuring the limiting effect on the slag removal plate 21 and preventing the limiting body 23 from falling off or loosening.
[0030] The working principle of this utility model is as follows: the limiting body 23 is pushed to slide in the sliding channel 22, the thrust part 24 is pushed into the sliding channel 22, the thrust part 24 and the limiting body 23 are locked with bolts, and the anti-slip protrusion 25 is inserted into the groove at the corresponding position to lock the position of the limiting body 23. The position of the limiting body 23 can be adjusted within a certain range, so that during the recovery stage of the output shaft of the boom 11, the angle between the slag removal plate 21 and the ground is obtuse or acute. When the output shaft of the boom 11 extends and pushes the mounting plate 20 and the slag removal plate 21 away from the base 10, the slag removal plate 21 will be squeezed and pushed by the slag and flip towards the base 10.
[0031] By passing the bolt through the through hole at the extension of the slag removal plate 21 and connecting it with the threaded hole on the wall of the slag removal plate 21, a hard connection can be formed between the slag removal plate 21 and the limiting body 23. The slag removal plate 21 can maintain a non-overturning slag removal operation. This is more suitable for the reciprocating extension and retraction characteristics of the fixed-point slag removal boom 11 in coal mines, which reduces the need to repeatedly raise the boom 11 due to the obstruction of the boom 11 by the slag removal plate 21.
