Description

Technical Field

[0001] This utility model belongs to the field of shovel plate technology, specifically relating to a shovel plate for loading coal mine tunneling machines. Background Technology

[0002] A coal mine tunneling machine is a type of mechanical equipment specifically used for tunneling underground coal mine roadways. It integrates functions such as cutting, loading, traveling, and operation, and is mainly used for cutting coal, semi-coal-rock, or soft rock roadways of any cross-section. When tunneling, the tunneling machine scrapes the coal from the coal seam through the tunneling head, and collects the scraped coal through the loading shovel plate installed at the front of the tunneling machine.

[0003] The top of the loading shovel of a tunneling machine is generally equipped with two sets of star wheels that can rotate in opposite directions, while the middle and rear section of the shovel is provided with a receiving groove for accommodating the front end of the tunneling machine's conveyor belt. Through the cooperation of the two sets of star wheels, the coal falling onto the shovel is pushed towards the conveyor belt, and the conveyor belt transports the coal backward, realizing the collection and loading of coal.

[0004] When carrying out tunneling work, it is necessary to select shovels of different widths according to the width of the tunnel. This is to prevent the shovels from being too wide to move in the tunnel, or too narrow to prevent the coal falling on both sides of the shovels from being collected. Therefore, when the tunnel is narrow, a narrower shovel is required, and when the tunnel is wide, a wider shovel is required. However, this means that when working in tunnels of different widths, the entire shovel needs to be replaced, which is time-consuming, labor-intensive, and has a higher operating cost. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a shovel loading mechanism for a coal mine tunneling machine, which includes a main shovel and an auxiliary shovel mechanism that can be quickly and easily disassembled. When operating in wider tunnels, the auxiliary shovel mechanism can be quickly installed on both sides of the main shovel to widen the shovel width without replacing the entire shovel, thereby increasing operating speed, simplifying the operation process, and reducing the cost of using the shovel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a loading shovel plate for a coal mine tunneling machine, including a main shovel plate, with connecting grooves on both sides of the main shovel plate, and an anti-detachment groove on the inner side of the connecting grooves. An auxiliary shovel plate mechanism is provided on both sides of the main shovel plate, the auxiliary shovel plate mechanism including a base, a docking device mounting groove on one side of the base, a docking device fixedly mounted on the inner side of the docking device mounting groove, a ramp block mounted on the top of the base, and an mounting groove inside the docking device, into which a first... The system includes a first positioning block and a second positioning block. One end of each positioning block is connected to a connecting arm, and one end of the connecting arm is connected to a rack. A rotating shaft is rotatably mounted inside the mounting groove. A gear is sleeved on the outside of the rotating shaft. The rack and the gear mesh with each other. A spring is installed inside the mounting groove, and one end of the spring is connected to the rack. Receiving holes are provided between the top surface of the base and the inside of the mounting groove of the docking device, and between the top and bottom of the ramp block.

Detailed Implementation

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0040] like Figures 1-9 As shown, a coal mine tunneling machine is equipped with a loading shovel, including a main shovel 1. Both sides of the main shovel 1 are provided with connecting grooves 5, and the inner side of each connecting groove 5 is provided with an anti-detachment groove 6. Both sides of the main shovel 1 are provided with auxiliary shovel mechanisms 7. Each auxiliary shovel mechanism 7 includes a base 8. One side of the base 8 is provided with a docking device mounting groove 9, and a docking device 10 is fixedly mounted inside the docking device mounting groove 9. A ramp block 11 is mounted on the top of the base 8. The docking device 10 has an mounting groove 13 inside, and a first positioning block 14 and a second positioning block 15 are inserted and installed inside the mounting groove 13. 14. One end of the second positioning block 15 is connected to a connecting arm 16, and one end of the connecting arm 16 is connected to a rack 17. A rotating shaft 18 is rotatably installed inside the mounting groove 13. A gear 19 is sleeved on the outside of the rotating shaft 18. The rack 17 and the gear 19 mesh with each other. A spring 22 is installed on the inside of the mounting groove 13. One end of the spring 22 is connected to the rack 17. Receiving holes 23 are provided between the top surface of the base 8 and the inside of the docking device mounting groove 9, and between the top and bottom of the ramp block 11. The top of the rotating shaft 18 extends into the inside of the receiving hole 23 and is connected to an internal hexagonal connector 24.

[0041] This device is equipped with a main shovel plate 1 and an auxiliary shovel plate mechanism 7 that can be quickly and easily disassembled. When operating in a wider tunnel, the auxiliary shovel plate mechanism 7 can be quickly installed on both sides of the main shovel plate 1 to widen the shovel plate without replacing the entire shovel plate, thereby increasing the operating speed, simplifying the operation process, and reducing the cost of using the shovel plate.

[0042] The top of the main shovel plate 1 is provided with two sets of star wheel mechanisms 3 that are symmetrically arranged on the left and right. The top of the main shovel plate 1 has a conveyor belt receiving groove 4 that is opened downward. The back of the main shovel plate 1 is equipped with a connecting lug 2. A frame connecting shaft hole and a hydraulic cylinder connecting shaft hole are provided through the two sides of the connecting lug 2.

[0043] When using this device, the main shovel plate 1 is installed at the front end of the tunneling machine. The main shovel plate 1 is connected to the tunneling machine frame and hydraulic cylinder respectively through the frame connecting shaft hole and hydraulic cylinder connecting shaft hole on the connecting lug 2. One end of the tunneling machine's conveyor belt extends into the inner side of the conveyor belt receiving trough 4. The star wheel mechanism 3 is driven by the hydraulic motor installed inside the main shovel plate 1, which plays a conveying role on the coal moving onto the main shovel plate 1, helping the coal to move onto the conveyor belt inside the conveyor belt receiving trough 4 and be transported backward.

[0044] The mounting groove 13 has a sliding groove 20 on its inner side, and the rack 17 has a sliding strip 21 on one side. The sliding strip 21 and the sliding groove 20 are slidably connected.

[0045] The sliding connection between the slide bar 21 and the slide groove 20 serves to limit the movement between the rack 17 and the inner wall of the mounting groove 13, thereby improving the installation stability of the rack 17.

[0046] The receiving hole 23 on the ramp block 11 has an internal thread and is threadedly connected to a threaded plug 25. A swivel ring 26 is connected to the top of the threaded plug 25.

[0047] The threaded plug 25 prevents coal ash from entering the interior of 23 and causing blockage, which would prevent the use of a hex wrench and internal hex connector 24 to unlock the main shovel plate 1 and the auxiliary shovel plate mechanism 7.

[0048] The ramp block 11 has a hollow structure.

[0049] The ramp block 11 has a hollow structure, which can reduce the overall weight of the auxiliary shovel mechanism 7.

[0050] A baffle 12 is installed on the top of both the main shovel plate 1 and the top of the ramp block 11.

[0051] By setting the baffle 12 on the main shovel plate 1, the shoveled coal can be prevented from leaking out from the side and rear of the main shovel plate 1. The baffle 12 on the auxiliary shovel plate mechanism 7 can also prevent coal from leaking out from the side and rear of the auxiliary shovel plate mechanism 7.

[0052] The bottom of the main shovel plate 1 is provided with a sealing plate slot 27, and a sealing plate 28 is slidably inserted into the sealing plate slot 27. A screw hole is provided between the top and bottom of the sealing plate 28. The side of the main shovel plate 1 is provided with a sealing plate receiving groove 29 at one end of the connecting groove 5. The sealing plate receiving groove 29 is also provided with a screw hole.

[0053] When the auxiliary shovel mechanism 7 is not in use, the sealing plate 28 is placed in the sealing plate receiving groove 29, and the bolts on the sealing plate 28 and the sealing plate receiving groove 29 are connected by bolts to fix the sealing plate 28. The sealing plate 28 seals the connecting groove 5 to prevent coal from entering the connecting groove 5 and causing blockage that is difficult to clean. When installing the auxiliary shovel mechanism 7, the sealing plate 28 is removed and slid into the sealing plate slot 27 for storage. Then the docking device 10 on one side of the auxiliary shovel mechanism 7 can be aligned with the connecting groove 5 and inserted.

[0054] The bottom of one end of the main shovel plate 1 is provided with an auxiliary reinforcing groove 30, and the bottom of the side of the auxiliary shovel plate mechanism 7 is provided with an auxiliary reinforcing plate 31.

[0055] When the auxiliary reinforcing groove 30 and the auxiliary reinforcing plate 31 are connected between the main shovel plate 1 and the auxiliary shovel plate mechanism 7, they are simultaneously inserted into each other as the docking device 10 and the connecting groove 5 are inserted, thereby enhancing the connection stability between the main shovel plate 1 and the auxiliary shovel plate mechanism 7.

[0056] The working principle and usage process of this utility model are as follows: When using this device, the main shovel plate 1 is installed at the front end of the tunneling machine. The main shovel plate 1 is connected to the tunneling machine frame and hydraulic cylinder respectively through the frame connecting shaft hole and hydraulic cylinder connecting shaft hole on the connecting lug 2. One end of the tunneling machine's conveyor belt is inserted into the inner side of the conveyor belt receiving groove 4, and it can be used immediately. During tunneling, the hydraulic cylinder of the tunneling machine drives the main shovel plate 1 to rotate through the fulcrum formed by the connection between the connecting lug 2 and the frame, so that the front end of the main shovel plate 1 contacts the ground, and the coal falling during the tunneling process is shoveled to the top of the main shovel plate 1. Through the cooperation of two sets of star wheel mechanisms 3, the coal is pushed to the conveyor belt inside the conveyor belt receiving groove 4 for backward transport. The baffle 12 located on the main shovel plate 1 can prevent the coal from being shoveled up. Coal leaks out from the side and rear end of the main shovel plate 1. Simultaneously, the device can be equipped with an auxiliary shovel plate mechanism 7 as needed. When the auxiliary shovel plate mechanism 7 is not in use, the sealing plate 28 is placed in the sealing plate receiving groove 29, and the bolts on the sealing plate 28 and the sealing plate receiving groove 29 are connected by bolts to fix the sealing plate 28. The sealing plate 28 seals the connecting groove 5, preventing coal from entering the connecting groove 5 and causing blockages that are difficult to clean. When installing the auxiliary shovel plate mechanism 7, the sealing plate 28 is removed and slid into the sealing plate slot 27 for storage. The docking device 10 on one side of the auxiliary shovel plate mechanism 7 can then be aligned with and inserted into the connecting groove 5. During insertion, under the pressure of the inner wall of the connecting groove 5, the first positioning block 14 and the second positioning block 1... 5 is squeezed into the inner side of the docking device 10, and drives the connecting arm 16 and the rack 17 to move, compressing the spring 22. When the docking device 10 is inserted into place, the first positioning block 14 and the second positioning block 15 are aligned with the anti-disengagement groove 6. Under the action of the spring 22's rebound force, the rack 17 drives the connecting arm 16 and the first positioning block 14 and the second positioning block 15 to reset, so that the first positioning block 14 and the second positioning block 15 are inserted into the anti-disengagement groove 6, thereby completing the fixation between the main shovel plate 1 and the auxiliary shovel plate mechanism 7. During the insertion of the connecting groove 5 and the docking device 10, the auxiliary reinforcing groove 30 and the auxiliary reinforcing plate 31 are also inserted into each other simultaneously, which plays a role in reinforcing the main shovel plate 1 and the auxiliary shovel plate mechanism 7. During the displacement of the rack 17 Because of the meshing between the rack 17 and the gear 19, the gear 19 and the rotating shaft 18 also rotate. After the installation of the auxiliary shovel mechanism 7 is completed, the width of this device is effectively increased, making it suitable for use in environments with wider roadways. It can handle a wider range of tasks, including receiving and shoveling coal cut by the tunneling machine drill bit. The auxiliary shovel mechanism 7 is equipped with a ramp block 11 and a baffle 12. The ramp block 11 is inclined towards the center of the main shovel 1, which allows the coal falling onto the auxiliary shovel mechanism 7 to move better onto the main shovel 1. At the same time, the baffle 12 on the auxiliary shovel mechanism 7 prevents coal from leaking out from the sides and rear of the auxiliary shovel mechanism 7. When it is necessary to disassemble the auxiliary shovel mechanism 7, only tools such as steel rods need to be inserted into the rotating ring 26.Rotating the swivel ring 26 removes the threaded plug 25. Then, inserting a hex wrench into the internal hex connector 24 rotates it, causing the shaft 18 and gear 19 to rotate. The gear 19 then drives two sets of racks 17 to move in opposite directions, causing the first positioning block 14 and the second positioning block 15 to retract into the docking device 10. At this point, the docking device 10 can be pulled out of the connecting groove 5, releasing the fixation between the main shovel plate 1 and the auxiliary shovel plate mechanism 7. In summary, this device features a main shovel plate 1 and an auxiliary shovel plate mechanism 7 that can be quickly and easily disassembled. When operating in wider tunnels, the auxiliary shovel plate mechanism 7 can be quickly installed on both sides of the main shovel plate 1 to widen the shovel plate without replacing the entire shovel plate, thus increasing operating speed, simplifying the operation process, and reducing the cost of using the shovel plate.
