Detailed Implementation
[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1
[0026] Please see Figure 1-6 This utility model relates to a flow control device for a gangue filling and conveying inlet, comprising a gangue funnel hopper 1, a wear-resistant frame 2 mounted on top of the gangue funnel hopper 1, L-shaped protective covers 3 fixedly connected to both sides of the gangue funnel hopper 1, a drive motor 4 fixedly connected to the bottom inside the L-shaped protective cover 3, a push-out mechanism above the drive motor 4, and a flow control mechanism below the drive motor 4; the push-out mechanism includes a lead screw 5 fixedly connected to the top of the drive motor 4, and a sliding sleeve 6 threadedly connected to the bottom of the lead screw 5. The front and rear sides of the sliding sleeve 6 are fixedly connected with ejector rods 7, and the inner walls on both sides of the sliding sleeve 6 are fixedly connected with electric push rods 8, which are used to eject the wear-resistant frame 2 through the ejector mechanism; the flow control mechanism includes a rotating rod 9 fixedly connected to the bottom of the drive motor 4, and a transmission component is provided at the bottom of the rotating rod 9. The L-shaped protective cover 3 is laterally rotatably connected to a screw 10, and a moving plate 11 is threadedly connected to one side of the surface of the screw 10. The moving plate 11 is slidably connected to the bottom of the gangue funnel bin 1 to control the flow rate of gangue.
[0027] Specifically: The wear-resistant frame 2 is made of high-chromium cast iron. High-chromium cast iron has high hardness and excellent wear resistance, making it especially suitable for high-impact and high-wear environments. There are two L-shaped protective covers 3 with identical internal structures, symmetrically arranged on both sides of the gangue funnel hopper 1. The flow rate is adjusted by the distance between the two sets of moving plates 11. The top of the screw 5 is rotatably connected to the top of the L-shaped protective cover 3 through a bearing seat, and one end of the screw 10 is rotatably connected to the inner wall of the L-shaped protective cover 3 through a bearing seat.
[0028] The L-shaped protective cover 3 has vertical slots on both sides inside for use with the electric push rod 8. The purpose of the vertical slots is to allow the output shaft of the electric push rod 8 to be inserted into the slots. When the output shaft of the electric push rod 8 is inserted into the slots, it can limit the sliding sleeve 6, and then the ejector rod 7 can move vertically normally. The purpose of the electric push rod 8 is to switch between different positions. When the electric push rod 8 is inserted into the slots, the sliding sleeve 6 is limited, and the ejector rod 7 can move vertically. When the output shaft of the electric push rod 8 is not inserted into the slots, the sliding sleeve 6 is in an unlimited state. At this time, the sliding sleeve 6 will rotate, and the ejector rod 7 will also rotate, but will not move vertically. This is the function and purpose of the electric push rod 8.
[0029] Example 2
[0030] Please see Figure 1-6 Based on Embodiment 1, a movable rod 12 is threadedly connected to one side of the screw 10 surface. Pointers 13 are fixedly connected to both sides of the bottom of the movable rod 12. A scale 14 is fixedly connected to the bottom of both sides of the gangue funnel hopper 1 to indicate the flow rate. The pointers 13 and scale 14 work together to indicate the opening and closing degree of the movable plate 11. The transmission components include a driving bevel gear 15 and a driven bevel gear 16. The driving bevel gear 15 is fixedly connected to the bottom of the rotating rod 9, and the driven bevel gear 16 is fixedly connected to one side of the screw 10 surface. The driven bevel gear 16 meshes with the driving bevel gear 15. The L-shaped protective cover 3 is in front of... The sides and rear sides are provided with sliding grooves 17, and the moving rod 12 is slidably connected to the sliding grooves 17. The wear-resistant frame 2 is made of high-chromium cast iron. The four corners of the top of the wear-resistant frame 2 are threaded with first bolts, which are used to fix the wear-resistant frame 2. The L-shaped protective cover 3 is provided with second bolts on both sides, which are used to fix the L-shaped protective cover 3. The top two sides of the L-shaped protective cover 3 are provided with through holes 18, the diameter of which is larger than the diameter of the ejector rod 7. A controller 19 is installed on one side of the surface of the gangue funnel bin 1. The controller 19 is electrically connected to the drive motor 4 and the electric push rod 8 through connecting wires.
[0031] Specifically: the sliding groove 17 can limit the movement of the moving rod 12, allowing it to move smoothly horizontally; the first bolt ensures the stability of the wear-resistant frame 2 during use; the second bolt ensures the safety of the L-shaped protective cover 3 during use; the through hole 18 allows the ejector rod 7 to move vertically; and the controller 19 controls the start and stop of the drive motor 4 and the electric push rod 8, enabling flow control and replacement of the wear-resistant frame 2.
[0032] The working principle of this utility model is as follows: When it is necessary to control the flow rate, the operator starts the drive motor 4 by operating the controller 19. The drive motor 4 drives the rotating rod 9 to rotate, the rotating rod 9 drives the active bevel gear 15 to rotate, the active bevel gear 15 drives the driven bevel gear 16 to rotate, the driven bevel gear 16 drives the screw 10 to rotate, the screw 10 drives the moving plate 11 to move, and while the screw 10 drives the moving plate 11 to move, it also drives the moving rod 12 to move. The moving rod 12 drives the pointer 13 to move. Based on the distance between the two pointers 13, the flow rate can be accurately calculated. When the flow rate is adjusted to a suitable level, the material can be continuously and stably supplied.
[0033] When the wear-resistant frame 2 is worn out and needs to be replaced, the worker first removes the first bolt with a wrench, then starts the electric push rod 8 through the controller 19, so that the output shaft of the electric push rod 8 is inserted into the vertical groove to complete the limit of the sliding sleeve 6. Then, the drive motor 4 is started normally through the controller 19. The drive motor 4 drives the lead screw 5 to rotate, the lead screw 5 and the sliding sleeve 6 move, the sliding sleeve 6 drives the ejector rod 7 to move. After the ejector rod 7 moves vertically, the wear-resistant frame 2 can be ejected from the inside of the gangue funnel hopper 1. Then, the old wear-resistant frame 2 can be removed and replaced with a new wear-resistant frame 2.
[0034] When the wear-resistant frame 2 needs to be replaced, the controller 19 starts the electric push rod 8, and the ejection mechanism ejects the wear-resistant frame 2; when the flow rate needs to be adjusted, the controller 19 starts the drive motor 4, and the flow control mechanism adjusts the opening and closing degree of the moving plate 11.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
