[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides an on-line coal slime scraping device as shown in Figures 1-5 which includes a main body 5 of the sump and a scraping trolley 7 installed inside the main body 5 of the sump;

[0029] Scraping plates 8 are arranged on both the left and right sides of the scraping trolley 7 to scrape the coal slime on the floor of the main body 5 of the sump;

[0030] Sedimentation tanks 4 are provided on both the left and right sides of the sump main body 5 to store the scraped coal slime;

[0031] Connecting blocks 18 are provided between the outer walls at both ends of the sludge scraping trolley 7 and the sludge scraping plates 8 to limit the positions of the sludge scraping plates 8. When cleaning the coal slime accumulated on the floor of the sump main body 5, first move the sludge scraping trolley 7 from left to right. After running to the middle position, lift the left sludge scraping plate 8 and lower the right sludge scraping plate 8. When the sludge scraping trolley 7 moves, the coal slime on the floor of the sump main body 5 can be cleaned for the first time. Subsequently, when the sludge scraping trolley 7 moves from right to left to the middle position, lift the right sludge scraping plate 8 and lower the left sludge scraping plate 8, and perform the sludge scraping operation again. During the left and right movement, the coal slime is scraped into the sedimentation tanks 4 on both sides;

[0032] A plurality of positioning rods 17 are equidistantly provided on the inner walls at both the front and rear ends of the sump main body 5 and are respectively close to both the left and right sides. Roller 16 is sleeved on the circular outer wall of each of the plurality of positioning rods 17. A fixing plate 15 is provided on the upper side of the sludge scraping trolley 7. When guiding the sludge scraping trolley 7 into the sump main body 5, the fixing plate 15 on the upper side of the sludge scraping trolley 7 is clamped and guided by the plurality of positioning rods 17 and rollers 16 on the upper and lower sides, so that when the sludge scraping trolley 7 moves onto the floor of the sump main body 5, the moving wheels 6 can maintain contact with the floor of the sump main body 5.

[0033] Such as Figure 2 、 Figure 3 And Figure 4 As shown, fixed rods 14 are fixedly connected to the outer walls at the upper ends of the sludge scraping trolley 7 and are respectively close to both the front and rear sides to limit the position of the fixing plate 15. There are two fixed rods 14 and fixing plates 15. The height between the plurality of positioning rods 17 gradually increases from left to right, and the fixing plate 15 can pass through and be clamped between the upper and lower sides of the plurality of positioning rods 17.

[0034] When guiding the sludge scraping trolley 7 into the sump main body 5, the fixing plate 15 on the upper side of the sludge scraping trolley 7 is clamped and guided by the plurality of inclined positioning rods 17 and rollers 16 on the upper and lower sides, so that the bottom end of the sludge scraping trolley 7 is in a flush state with the floor of the sump main body 5.

[0035] Such as Figure 5 As shown, mud-breaking plates 22 are provided on one side of each of the two sludge scraping plates 8. Connecting rods 21 are fixedly connected to one end of the opposite sides of the two sludge scraping plates 8. Push plates 20 that penetrate upward into the connecting blocks 18 are fixedly connected to one end of the opposite sides of the two connecting rods 21 to drive the coal slime that has not been scraped by the sludge scraping plates 8 to move. Sliding grooves 19 for the push plates 20 to move are provided inside the two connecting blocks 18.

[0036] When the sludge scraping plate 8 moves left and right to scrape the slime on the floor of the sump main body 5, the accumulated slime can be broken and loosened by the mud breaking plate 22, which can accelerate the speed of the sludge scraping plate 8 when scraping the slime. At the same time, when the sludge scraping plate 8 is lifted and lowered, the slime accumulated between the movable wheels 6 can be moved by the push plate 20, and when the sludge scraping plate 8 moves up and down, the push plate 20 can be driven to move up and down by the connecting rod 21.

[0037] As Figure 1 shown, a coal mine main body 1 is arranged outside the sump main body 5. Inside the coal mine main body 1 and respectively near the left and right sides, inlets 11 are arranged for personnel and equipment to enter the inside of the sump main body 5. A guiding channel 10 is arranged between the two inlets 11 and the sump main body 5, and a endless rope winch 2 is arranged on the lower inner wall of the left inlet 11.

[0038] When moving the sludge scraping trolley 7 into the sump main body 5, the sludge scraping trolley 7 can be guided into the sump main body 5 through the inlet 11 and the guiding channel 10.

[0039] As Figure 1 shown, a fixator 13 is arranged on the lower inner wall of the right inlet 11, a tensioning guiding wheel 12 is arranged on the left side of the fixator 13, and a plurality of guiding wheels 3 are equidistantly arranged on the inner walls of the front, back, left and right ends of the two inlets 11, the guiding channel 10 and the sump main body 5. A steel wire rope 24 is arranged between the endless rope winch 2, the guiding wheels 3, the sludge scraping trolley 7 and the tensioning guiding wheel 12 to cooperate with each other to drive the sludge scraping trolley 7 to move in the left and right directions.

[0040] A steel wire rope 24 is wound between the endless rope winch 2, the guiding wheels 3, the sludge scraping trolley 7 and the tensioning guiding wheel 12. When the endless rope winch 2 is working, it is composed of a motor, a speed reducer and a drum to provide power for the sludge scraping trolley 7. After being decelerated by the speed reducer by the motor, the drum rotates forward and backward, thereby driving the steel wire rope 24 to form a closed-loop operation system between the tensioning guiding wheel 12 on the other side and the sludge scraping trolley 7 under the guidance of the guiding wheels 3, so as to drive the sludge scraping trolley 7 to move in the left and right directions.

[0041] As Figure 1 and Figure 5 shown, a sludge scraping reversing mechanism 23 is arranged inside the connecting block 18 to drive the two sludge scraping plates 8 to move up and down. A reversing trigger device 9 is arranged on the upper inner wall of the sump main body 5 to control the opening of the sludge scraping reversing mechanism 23 after contacting the sludge scraping reversing mechanism 23. A plurality of moving wheels 6 are arranged on the lower outer wall of the sludge scraping trolley 7 and respectively near the left and right sides.

[0042] After the sludge scraping trolley 7 moves to the central area inside the sump main body 5, the reversing trigger device 9 will trigger the sludge scraping reversing mechanism 23 in the sludge scraping trolley 7, causing the two sludge scraping plates 8 to move up and down respectively to push the sludge inside the sump main body 5 in different directions.

[0043] The implementation principle of this embodiment is as follows: When cleaning the sludge accumulated on the floor of the sump main body 5, first move the sludge scraping trolley 7 from left to right. After running to the middle position, lift the left sludge scraping plate 8 and lower the right sludge scraping plate 8. When the sludge scraping trolley 7 moves, the sludge on the floor of the sump main body 5 can be cleaned for the first time. Subsequently, after the sludge scraping trolley 7 moves from right to left to the middle position, the right sludge scraping plate 8 is lifted and the left sludge scraping plate 8 is lowered for sludge scraping operation again. During the left and right movement process, the sludge is scraped into the sedimentation tanks 4 on both the left and right sides. When guiding the sludge scraping trolley 7 into the sump main body 5, the fixing plate 15 on the upper side of the sludge scraping trolley 7 is clamped and guided by a plurality of positioning rods 17 and rollers 16 on the upper and lower sides, so that when the sludge scraping trolley 7 moves onto the bottom plate of the sump main body 5, the contact between the moving wheels 6 and the floor of the sump main body 5 can be maintained.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
