The scraper conveyor at the rear is used to transport the coal roof fragments that collapse from the top behind the hydraulic support as it moves forward.

[0003] When collecting the coal top at the rear, the existing hydraulic support only withdraws the rear support arm, causing the coal top to fall completely onto the scraper conveyor at the rear under the action of gravity. However, when the coal blocks are not completely crushed, they are large in size and easily get stuck on the scraper conveyor, causing the scraper to be unable to move forward. Manual or external machine cooperation is required for cleaning, which affects the coal collection speed and efficiency of the hydraulic support when in use.

[0027] It should be noted that the guide seat 5 and the guide block 10 are used to guide the movement of the mobile frame 9, the bevel gears 12 are meshed with each other to change the transmission direction, leaving space for the installation of the mobile motor 11, and the push rod 14 can push the lifting rack 21 to rise and fall on one side of the mounting plate 19 by contact and extrusion when moving, and then drive the first rack 17 to move by meshing with the flip gear 20, and then push the swivel seat 15 to move, and drive the baffle door 13 to flip the angle through the change in the angle between it and the connecting rod 16, so that it opens, which is convenient for the coal crushing rod 24 to be moved out synchronously, and the mounting plate 19 is used to fix the flip gear 20 and the lifting rack 21, and the spring 18 is used to reset the swivel seat 15 when it is not under force. Through the storage component set up, the circulating coal crushing component can be hidden when not in use to avoid it affecting the normal supporting coal roof function of the hydraulic support. At the same time, it can also be extended to work when needed and retracted for protection when not needed, thereby improving the service life of the circulating coal crushing component.

[0028] A circulating coal crushing assembly includes a slide 4 provided on the front and rear sides of the movable frame 9, a movable seat 22 is slidably connected in the slide 4, a crushing motor 23 is fixedly connected to one side of the movable seat 22, a coal crushing rod 24 is rotatably connected to the other side of the movable seat 22, one end of the coal crushing rod 24 is fixedly connected to the output end of the adjacent crushing motor 23, a second rack 25 is also fixedly connected to one side of the movable seat 22, a bracket 26 is fixedly connected to the middle of the same side of the movable frame 9 as the second rack 25, a reciprocating motor 27 is fixedly connected to one side of the bracket 26, a reciprocating motor 27 is fixedly connected to the output end of the reciprocating motor 27 is fixedly connected to a reciprocating gear 28, and the reciprocating gear 28 is meshed with the adjacent second rack 25. Through the circulating coal crushing assembly, the coal blocks in the rear scraper conveyor can be crushed after the hydraulic support retracts the side extension arm 2 during operation, thereby avoiding the problem of accumulation and jamming of the machine due to its large volume, ensuring the normal coal collection speed and efficiency of the hydraulic support during use, and reducing the failure rate.

[0029] It should be noted that the slide 4 is used to guide the movable seat 22, and the reciprocating gear 28 is driven to intermittently rotate forward and reverse through the output end of the reciprocating motor 27, and the movable seat 22 and the coal crushing rod 24 on both sides are driven to reciprocate and perform crushing motion through the engagement with the adjacent second rack 25, thereby expanding the coal crushing range in the scraper conveyor, improving the coal crushing effect, and accelerating the coal collection speed.

[0030] In this embodiment, one end of the lateral push rod 14 close to the lifting rack 21 is set as an inclined surface, and the front cross-sectional shape of the lifting rack 21 is a right-angled trapezoid. The inclined surfaces abut each other to facilitate the lateral push rod 14 to push the lifting rack 21 upward when it moves horizontally, thereby changing the transmission direction.

[0031] In this embodiment, at the rear flip gear 20, the adjacent lateral push rod 14 is located in front of it, and the adjacent first rack 17 is located behind the lateral push rod 14 and the lifting rack 21. By limiting the positions of each component, interference between their mutual working processes can be avoided, thereby ensuring reliable and stable operation of the structure.

[0032] In this embodiment, the two second racks 25 are staggered about the same reciprocating gear 28, and are symmetrical about the central axis of the reciprocating gear 28. The staggered arrangement allows the second racks 25 and the reciprocating gear 28 to engage without interfering with each other, and when the reciprocating gear 28 rotates unidirectionally, the two second racks 25 can move relative to each other, thereby facilitating the control of the relative movement of the movable seats 22 on both sides to crush the coal and expand the coal crushing range.

[0033] In this embodiment, the transmission ratios of the flip gear 20 meshing with the first rack 17 and the lifting rack 21 are consistent. By setting the transmission ratios consistent, the rising height of the lifting rack 21 can be consistent with the horizontal moving distance of the swivel seat 15, which is convenient for designing the size of the lifting rack 21.

[0034] In this embodiment, a through hole is opened on the swivel seat 15, and an insertion shaft is fixedly connected to one side of the connecting rod 16. The insertion shaft is movably connected in the through hole on the adjacent swivel seat 15. The cooperation between the through hole and the insertion shaft can facilitate the connection between the connecting rod 16 and the swivel seat 15, which is convenient for installation.

[0035] When the present invention is used in practice, when it is necessary to crush the coal blocks poured into the scraper conveyor behind the hydraulic support body 1 and assist in collecting the coal, the controller controls the mobile motor 11 and the crushing motor 23 to work, the crushing motor 23 drives the coal crushing rod 24 to rotate, the mobile motor 11 drives the bevel gear 12 to rotate, and the mutual engagement of the bevel gear 12 drives the screw rod 7 to rotate, and the threaded cooperation between the screw rod 7 and the slider 8 drives the slider 8 and the mobile frame 9 to move to the side close to the baffle door 13, and at the same time, the mobile frame 9 will abut against the lifting rack 21 through the horizontal push rod 14 to push the lifting rack 21 up, and when the lifting rack 21 rises, it will contact with the flip gear 20 The meshing drives the first rack 17 to move, and then drives the swivel seat 15 to move toward the side close to the baffle door 13. The baffle door 13 is rotated outward and opened by the change in the angle between the connecting rod 16, the swivel seat 15 and the baffle door 13, so that the movable coal crushing rod 24 is extended. At the same time, the reciprocating motor 27 is controlled by the controller to work, and the reciprocating motor 27 drives the reciprocating gear 28 to rotate. The meshing between the reciprocating gear 28 and the second rack 25 drives the movable seat 22 to slide in the slide groove 4, thereby realizing the relative movement of the two coal crushing rods 24. The moving direction of the coal crushing rod 24 is controlled by controlling the forward and reverse rotation of the output end of the reciprocating motor 27, so that the coal crushing range can be expanded.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
