[0002] Mining feeders are belt conveyors used for transporting materials in mines. They use multiple idlers to carry the load. To prevent material spillage, leakage, or dust, they are usually equipped with guide chutes. Guide chutes can be divided into those with anti-overflow skirts and those that are fully enclosed. If it is a fully enclosed type, it consists of three parts: upper, middle, and lower. The middle side plate is connected to the conveyor frame and is a fixed part. The top cover and the bottom plate are connected to the side plates with bolts, which can be easily disassembled for installation and maintenance.

[0003] Currently, in order to ensure the sealing of closed feed chutes, the anti-overflow skirt and the belt must be in close contact.

The upper part of the overflow skirt plate 5 is connected to the outer side plate 11, and the first support edge 51 and the second support edge 52 are located at the lower part of the overflow skirt plate 5. A soft skirt edge 54 is flexibly connected to the end of the second support edge 52, and both the first support edge 51 and the soft skirt edge 54 are in close contact with the belt 4. A central connecting rib 53 is also provided between the first support edge 51 and the second support edge 52.

[0022] The first embodiment of this utility model is as follows:

[0023] A feeder chute for a mining machine includes a base 1. A roller assembly is provided on the upper part of the base 1. The roller assembly includes several supports 2 fixedly provided on the upper part of the base 1. A lower roller 3 is provided at the middle position of the upper part of the supports 2. Side rollers 15 are provided on both sides of the upper part of the supports 2. The side rollers 15 are inclinedly provided on both sides of the lower roller 3. A belt 4 is located above the lower roller 3 and the side rollers 15. The lower roller 3 and the two side rollers 15 are used to make the belt 4 form an arc-shaped structure with the sides higher than the middle.

[0024] The upper part of the idler roller assembly is also provided with a trough assembly, which forms a sealed structure with the belt. The trough assembly includes columns 6 fixedly installed on both sides of the upper part of the base 1. A lower cross arm 7 is fixedly installed in the middle of the column 6. A mounting plate 8 is fixedly installed on the upper part of the lower cross arm 7. A support slide plate 10 is detachably installed on the upper part of the mounting plate 8. The inclination angle of the support slide plate 10 is the same as that of the side idler roller 15. An upper cross arm 12 is fixedly installed on the upper part of the column 6. An outer side plate 11 is fixedly installed at the end of the upper cross arm 12. A top cover 13 is fixedly installed on the upper part of the two outer side plates 11, forming a rectangle. A cover of the shape is placed over the upper part of the belt 4. The lower end of the outer side plate 11 is connected to the upper surface of the support slide plate 10. The support slide plate 10 is provided with a loop groove 9 extending along the direction of the belt 4. The edge of the belt is located inside the loop groove 9. Thus, the top cover 13, the outer side plate 11, the support slide plate 10 and the belt 4 form an external sealing structure. In particular, the edge of the belt 4 is located inside the loop groove 9. On the one hand, it can prevent the edge of the belt 4 from fluctuating and affecting the sealing effect. On the other hand, it can also form a loop sealing structure with the support slide plate 10 and the belt 4, resulting in a better sealing effect.

[0025] The support slide 10 is made of ultra-high molecular weight wear-resistant material, which can reduce the friction between the support slide 10 and the belt 4.

[0026] An inner guide plate 14 is fixedly installed on the inner side of the outer side plate 11. The inner guide plate 14 is inclined inward. The lower part of the inner guide plate 14 is detachably connected to the anti-overflow skirt plate 5. The upper part of the anti-overflow skirt plate 5 is connected to the outer side plate 11. The first support edge 51 and the second support edge 52 are located at the lower part of the anti-overflow skirt plate 5. The first support edge 51 and the soft skirt edge 54 are in close contact with the belt 4. The first support edge 51 faces the direction of the support slide plate 10, and the second support edge 52 faces the other direction, forming a Y-shaped support. The original single-point contact is changed to two-point contact. Under the condition of constant pressure, the contact area is increased and the pressure is reduced, which effectively reduces wear.

[0027] Furthermore, the end of the second support edge 52 is flexibly connected with a soft skirt 54. When the second support edge 52 contacts the belt 4, the soft skirt 54 is flattened and makes overall contact with the belt 4, further increasing the contact area, reducing pressure, and effectively reducing wear.

[0028] Furthermore, a central connecting rib 53 is provided between the first support edge 51 and the second support edge 52, which strengthens the structural strength of the first support edge 51 and the second support edge 52, so that the first support edge 51 and the second support edge 52 can always maintain contact with the belt 4, thereby improving the sealing effect.

[0029] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0030] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
