Description

Technical Field

[0001] The present invention relates to the technical field of underground coal mine desilting equipment, and more specifically, to an underground coal mine crawler desilting machine with an anti-clogging mechanism. Background Art

[0002] The underground water bunker of a coal mine is an important facility for ensuring safe production and preventing floods in the coal mine. With the extension of mining and the increase in water inflow in the mine, a large amount of coal (rock) mud enters the water bunker with the mine drainage and gradually accumulates at the bottom of the water bunker, which reduces the effective water storage capacity of the underground water bunker and requires timely cleaning. In actual production, due to the different sizes of the water bunkers built, it is necessary to select appropriate coal mine silt removal equipment when cleaning the coal mud in the water bunker. Coal mine silt removal equipment has very important practical significance for reducing the labor intensity of workers, increasing the cleaning speed of water bunkers, reducing the occurrence of water disasters, and ensuring safe production in mines.

[0003] For example, utility model patent CN220550615U discloses a desilting device for coal mine water tanks, which uses a crawler drive unit, has stable running and is not easy to roll over. The lower scraper is opened by hydraulic drive to remove the silted coal sludge sediment. A roller is installed in the bucket, and the first drive motor drives the roller to rotate, driving the spiral blade to cut and break large pieces of silt, preventing the silt suction pipe from being blocked, ensuring smooth desilting, and sucking the silt into the storage box through the negative pressure suction of the sludge pump, without the need for manual shoveling of silt, thereby improving work efficiency;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In view of the fact that in the prior art, due to the lack of a structure for separately separating and crushing large pieces of minerals or debris in the sludge, when sucking the sludge, the large pieces of minerals or debris mixed in it will block and damage the sludge sucking device on the silt cleaner, thereby affecting the continuous use of the crawler silt cleaner in the coal mine, in order to solve this problem, the following technical solution is proposed:

[0027] Refer to the instruction manual Figure 1-Figure 7 , underground crawler silt remover with anti-clogging mechanism, such as Figure 1 and Figure 2 As shown, the silt remover 1 includes crawler wheels 2 on both sides of the silt remover 1, a silt suction cylinder 3 is provided on one side of the silt suction cylinder 3, and a sieve collection mechanism 4 and a blocking mechanism 5 are provided on one side of the silt suction cylinder 3;

[0028] like Figure 3 and Figure 4 As shown, the bag screen collection mechanism 4 includes a support frame 41 fixedly mounted on the top outer wall of the dredging machine 1, a middle bracket 42 fixedly mounted on the bottom of the support frame 41, the middle bracket 42 is arranged in a vertical state, rotating rods 43 are rotatably mounted on both sides of the middle bracket 42, the rotating rods 43 are arranged in a horizontal state, a bag screen 44 is fixedly mounted on the bottom outer wall of the rotating rod 43, the bottom of the bag screen 44 is arranged inclined upward, and side baffles 45 are fixedly mounted on both sides of the bag screen 44, the rotating rod 43 driven by the support frame 41 and the middle bracket 42, the bag screen 44 and the side baffles 45 at the bottom thereof form a bucket-shaped structure, the bag screen 44 and the side baffles 45 are used to filter the sludge to be sucked in at the front side of the sludge suction cylinder 3, thereby isolating the large minerals or debris therein.

[0029] like Figure 3 and Figure 4 As shown, a support plate 46 is provided at the bottom of the bag screen 44, and the support plate 46 is fixedly mounted on the outer wall of the sludge suction cylinder 3. The support plate 46 is arranged in a horizontal state, and the top of the support plate 46 is arranged in a triangular shape. The top of the support plate 46 fits the bottom of the bag screen 44, and the length of the support plate 46 is the same as the length of the bag screen 44. The sludge at the bottom is shoveled up by the support plate 46 so that the bag screen 44 can completely filter the sludge.

[0030] like Figure 3 and Figure 4As shown, driving gears 47 are fixedly installed on both sides of the rotating rod 43, and the two driving gears 47 are symmetrically arranged. A tooth plate 48 is meshed on one side of the two driving gears 47, and the two tooth plates 48 are arranged in a vertical state. Electric telescopic cylinders 49 are fixedly installed on the top of the two tooth plates 48, and the electric telescopic cylinders 49 are fixedly installed on the bottom of the support frame 41. The two electric telescopic cylinders 49 are started and drive the tooth plates 48 to move up respectively, so that the tooth plates 48 can push the driving gears 47 on both sides to rotate synchronously, and the driving gears 47 on both sides synchronously drive the rotating rod 43 to rotate, that is, the rotating rod 43 drives the material screen 44 to flip upward and take the isolated large minerals or debris away from the silt.

[0031] like Figure 4 and Figure 5 As shown, the blocking mechanism 5 includes a driven gear 51 arranged at the bottom of the two driving gears 47. The two driven gears 51 are meshed with the two tooth plates 48. The two driven gears 51 are symmetrically arranged. The area of ​​the driven gear 51 is larger than the area of ​​the driving gear 47, that is, the rotation amplitude of the two driven gears 51 is smaller than the rotation amplitude of the two driving gears 47, and then the two tooth plates 48 drive the two driven gears 51 to rotate synchronously when they move up.

[0032] like Figure 4 and Figure 5 As shown, a rotating shaft 52 is fixedly installed on one side of the two driven gears 51, and the rotating shaft 52 is rotatably installed on the inner wall of the middle bracket 42. A partition net 53 is fixedly installed on the bottom of the rotating shaft 52.

The driven gear 51 drives the rotating shaft 52 to make the partition net 53 synchronously flip upward, that is, the partition net 53 is lifted to the position of the bag screen 44 and corresponds to the support plate 46. At this time, the partition net 53 isolates large minerals or debris on the outside while filtering the sludge, so as to prevent large minerals or debris from entering the sludge suction cylinder 3 when the bag screen 44 flips away.

[0033] like Figure 6 and Figure 7 As shown, a crushing mechanism 6 is provided on the top of the bag screen 44, and the crushing mechanism 6 includes a connecting plate 61 fixedly installed on the outer wall of the dredging machine 1, and a receiving hopper 62 is fixedly installed on one side of the connecting plate 61. The receiving hopper 62 is fixedly installed on the outer wall of the middle bracket 42, and the middle bracket 42 is located on the top of the bag screen 44. When the bag screen 44 flips upward, the large pieces of minerals or debris driven by it move upward, and are poured backwards through the tilt of the bag screen 44, that is, poured into the receiving hopper 62.

[0034] like Figure 6 and Figure 7As shown, a guide plate 63 is fixedly installed on one side of the top of the receiving hopper 62, and the guide plate 63 is set to be inclined downward. A limiting partition plate 64 is fixedly installed on the other side of the top of the receiving hopper 62, and the limiting partition plate 64 is set to be inclined downward. The guide plate 63 and the limiting partition plate 64 on the receiving hopper 62 guide the poured large pieces of minerals or debris to the middle.

[0035] like Figure 6 and Figure 7 As shown, a crusher 65 is provided inside the receiving hopper 62, and the crusher 65 is located at the bottom of the guide plate 63 and the limiting partition plate 64. The bottom of the receiving hopper 62 is connected to a lead-out bin 66, and the lead-out bin 66 is arranged to be inclined downward. Large pieces of minerals or debris falling from the middle enter the crusher 65, that is, the crusher 65 crushes them, and the crushed minerals or debris fall from the lead-out bin 66 into the front side of the sludge suction cylinder 3 and are sucked in.

[0036] In the specific implementation, the rotating rod 43 driven by the support frame 41 and the middle bracket 42, the bag screen 44 and the side baffle 45 at the bottom thereof form a bucket-shaped structure, and the bag screen 44 and the side baffle 45 are used to filter the sludge to be sucked in at the front side of the sludge suction cylinder 3, so as to isolate the large pieces of minerals or debris therein. At this time, the two electric telescopic cylinders 49 are started and respectively drive the toothed plates 48 to move upward, and then the toothed plates 48 can drive the driving gears 47 on both sides to rotate synchronously, and the driving gears 47 on both sides synchronously drive the rotating rod 43 to rotate, that is, the rotating rod 43 drives the bag screen 44 to flip upward and take the isolated large pieces of minerals or debris away from the sludge;

[0037] At the same time, the two tooth plates 48 move upward and drive the two driven gears 51 to rotate synchronously, and the driven gears 51 drive the rotating shaft 52 to make the partition 53 flip upward synchronously, that is, the partition 53 is lifted to the position of the bag screen 44 and corresponds to the pad support plate 46. At this time, the partition 53 isolates large minerals or debris on the outside while filtering the sludge, so as to prevent large minerals or debris from entering the sludge suction cylinder 3 when the bag screen 44 flips away;

[0038] When the bag screen 44 flips upward, the large pieces of minerals or debris moved up are poured backwards through the tilt of the bag screen 44, that is, poured into the receiving hopper 62, and the large pieces of minerals or debris falling from the middle enter the crusher 65, that is, the crusher 65 crushes them, and the crushed minerals or debris fall from the outlet bin 66 into the front side of the sludge suction cylinder 3 and are sucked in, so as to achieve the effect of completely sucking out the sludge, thereby improving the use effect of the crawler silt remover in the coal mine.
