[0001] This utility model relates to the field of coal mine transportation equipment technology, and in particular to a movable guide chute for the head of a scraper conveyor. Background Technology

[0002] In underground coal mining operations, scraper conveyors play a crucial role in transferring raw coal to the self-moving tail of belt conveyors. The feed chute, as a vital component of the scraper conveyor's head section, significantly impacts the smoothness and efficiency of the raw coal transfer process. Its performance directly affects the efficiency and orderliness of production, the recycling of raw coal, and the cleanliness of the production environment, making it a vital link in ensuring safe production in underground coal mines.

[0003] The movable feed chute installed at the head of the scraper conveyor is directly related to the efficient and safe production of coal mines. In fully mechanized mining faces, the scraper conveyor transfers raw coal to the self-moving tail of the belt conveyor. The raw coal falls onto the conveyor belt and is carried away. Due to reasons such as poor sealing and severe deformation of the feed chute, the raw coal spills outside the conveyor belt, accumulates on the frame of the self-moving tail, and even falls to the ground, causing great waste and making cleanup laborious, thus affecting mine production. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology that the material trough is not properly sealed and is severely deformed, which causes raw coal to spill outside the conveyor belt, accumulate on the frame of the self-moving machine tail, or even fall to the ground, resulting in great waste. Therefore, a movable guide trough for the head of a scraper transfer machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a movable guide chute for the head of a scraper conveyor, comprising an annular steel plate, with an outer L-shaped plate fixedly connected to the bottom and near both sides of the annular steel plate, an inner L-shaped plate provided inside the outer L-shaped plate, a connecting plate fixedly connected between the outer L-shaped plate and the inner L-shaped plate, an inclined plate fixedly connected to one end of the outer L-shaped plate and the inner L-shaped plate, a square hole provided on the surface of the inclined plate near both ends, a hydraulic cylinder provided inside the square hole, a baffle pin connected to the inside of the annular steel plate near both bottom sides, two fixing blocks fixedly connected to the bottom of the baffle near the four corners, a rotating component pin connected between the fixing blocks, a fixing plate installed at the bottom of the inner L-shaped plate, a trapezoidal plate fixedly connected to one end of the fixing plate, a groove provided on the inclined side of the trapezoidal plate, a mounting plate embedded and pin connected inside the groove, and both ends of the hydraulic cylinder fixedly connected to the rotating component and the mounting plate.

[0006] Preferably, the annular steel plate has convex grooves on both sides and near the top, and a connecting cover plate is embedded in the interior of each convex groove. The top of the annular steel plate and near the four corners of the top are fixedly connected to protrusions. A rotating rod is pin-connected between the protrusions, and the rotating rod is fixedly connected to the connecting cover plate.

[0007] Preferably, the bottom inner wall of the convex groove is provided with a groove near the center.

[0008] Preferably, a triangular plate is fixedly connected to the top of the outer L-shaped plate and near the center, and the triangular plate is fixedly connected to the annular steel plate.

[0009] Preferably, wear-resistant sliding strips are fixedly installed on the surface of the inclined plate and near the bottom.

[0010] Preferably, the outer L-shaped plate and the inner L-shaped plate are connected by two rollers near the bottom with pins, and the outer L-shaped plate is embedded with a guide rail at the bottom.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the combination of annular steel plate and adjustable baffle (controlled by hydraulic cylinder, rotating parts, etc.) and cover plate can achieve precise adjustment of the material guiding space and sealing state inside the material guiding trough.

An inner L-shaped plate 8 is provided inside each outer L-shaped plate 7. A connecting plate 9 is fixedly connected between the outer L-shaped plate 7 and the inner L-shaped plate 8, which increases the strength between the outer L-shaped plate 7 and the inner L-shaped plate 8. An inclined plate 13 is fixedly connected to one end of the outer L-shaped plate 7 and the inner L-shaped plate 8. Square holes 15 are opened on the surface of the inclined plate 13 near both ends. Hydraulic cylinders 23 are installed inside each square hole 15. The annular steel plate 1 is located inside the annular steel plate 1 near the bottom. Both sides of the baffle 16 are pin-connected to the baffle 16. Two fixing blocks 17 are fixedly connected to the bottom of the baffle 16 and near the four corners. A rotating part 18 is pin-connected between the fixing blocks 17. A fixing plate 19 is installed at the bottom of the inner L-shaped plate 8.

[0023] Example 2, as Figure 1-4 As shown, both sides of the annular steel plate 1 are provided with convex grooves 2 near the top, and connecting cover plates 5 are embedded inside the convex grooves 2. The top of the annular steel plate 1 is fixedly connected with protrusions 3 near the top four corners. Rotating rods 4 are pin-connected between the protrusions 3 and fixedly connected to the connecting cover plates 5. The bottom inner wall of the convex grooves 2 is provided with grooves 6 near the center. The top of the outer L-shaped plate 7 is fixedly connected with triangular plates 10 near the center and fixedly connected to the annular steel plate 1. Wear-resistant sliding strips 14 are fixedly installed on the surface of the inclined plate 13 near the bottom. Two rollers 12 are pin-connected between the outer L-shaped plate 7 and the inner L-shaped plate 8 near the bottom. Guide rails 11 are embedded below the outer L-shaped plate 7.

[0024] The overall effect of embodiment 2 is as follows: Convex grooves 2 are provided on both sides of the annular steel plate 1 near the top; connecting cover plates 5 are embedded inside the convex grooves 2; protrusions 3 are fixedly connected to the top of the annular steel plate 1 near the four corners; rotating rods 4 are pin-connected between the protrusions 3; and the rotating rods 4 are fixedly connected to the connecting cover plates 5, which allows the connecting cover plates 5 to rotate around the rotating rods 4 to cover the top of the annular steel plate 1; grooves 6 are provided on the bottom inner wall of the convex grooves 2 near the center, which allows the connecting cover plates 5 to be pulled through the grooves 6; and the outer L... Triangular plates 10 are fixedly connected to the top of the L-shaped plate 7 and near the center. The triangular plates 10 are fixedly connected to the annular steel plate 1, which can improve the stability of the annular steel plate 1 and the outer L-shaped plate 7. Wear-resistant sliding strips 14 are fixedly installed on the surface of the inclined plate 13 and near the bottom, which can make the wear-resistant sliding strips 14 adhere to the surface of the conveyor belt. Two rollers 12 are connected by pins between the outer L-shaped plate 7 and the inner L-shaped plate 8 and near the bottom. Guide rails 11 are embedded under the outer L-shaped plate 7, which can make the rollers 12 move on the guide rails 11.

[0025] Working principle: The guide chute moves along the guide rail 11 by rolling rollers 12 at the bottom of the outer L-shaped plate 7 and the inner L-shaped plate 8. When the scraper conveyor or belt conveyor adjusts its position due to production needs, the guide chute can slide on the guide rail 11 via the rollers 12 to quickly adapt to the new docking position, ensuring smooth raw coal transfer. After the raw coal enters the annular steel plate 1, the opening angle of the baffle 16 is controlled by the rotating component 18 driven by the hydraulic cylinder 23. The extension and retraction of the hydraulic cylinder 23 drives the rotating component 18 to rotate, thereby changing the angle of the baffle 16. When material guidance is required, the baffle 16 is adjusted to a suitable angle to guide the raw coal to fall precisely onto the conveyor belt. At the same time, by adjusting the angle of the baffle 16, a tight sealing space is formed between the annular steel plate 1 and the baffle 16 to prevent the raw coal from overflowing, achieving synergy between material guidance and sealing functions. The outer L-shaped plate 7 and the inner L-shaped plate 8 are firmly connected by the connecting plate 9 to ensure the structural strength of both sides of the material guide chute. The triangular plate 10 reinforces the connection between the annular steel plate 1 and the outer L-shaped plate 7, improving the overall resistance to deformation. The wear-resistant sliding strip 14 resists wear when the inclined plate 13 comes into contact with the raw coal and other components, extending the service life of the inclined plate 13. The two ends of the hydraulic cylinder 23 are respectively connected to the baffle 16, the rotating part 18, the inner L-shaped plate 8, the trapezoidal plate 20, and the insert plate 22 in the groove 21. Utilizing the rotational characteristics of the pin connection, hydraulic energy is converted into mechanical force to precisely control the state of the baffle 16. All components cooperate with each other to build a stable and efficient material guidance operation system, ensuring the orderly transfer of raw coal from the scraper transfer machine to the belt conveyor.
