Description

Technical Field

[0001] This utility model belongs to the field of coal transportation technology, and in particular relates to a maintenance-free auxiliary device for feeding coal in a coal conveying system. Background Technology

[0002] Conveyor belt misalignment is a frequent occurrence in coal transport plants. Long-term practice has revealed that the primary cause is uneven stress on the conveyor belt due to the excessively uneven distribution of coal after feeding. When coal is discharged from the feed bunker onto the conveyor belt, the uneven flow rate causes faster-moving coal to fall along the left or right side of the feed channel, resulting in coal accumulation on one side of the conveyor belt. After a period of transport, the conveyor belt will misalign. Currently, the common solution is to reduce the coal conveying rate to standardize the coal drop point. However, this method not only reduces transport efficiency but also requires additional control design, further increasing transport costs. Utility Model Content

[0003] To address the problem of conveyor belt misalignment during coal transport as described in the background art, this utility model proposes the following technical solution:

[0004] A maintenance-free material feeding auxiliary device for a coal conveying system, installed above a coal conveyor belt, includes: a chute, multiple support seats, two material feeding plates, and two sets of adjusting components; the chute is fixedly installed between a storage bin and the coal conveyor belt, and has a feeding channel for conveying coal, with multiple guide holes on the feeding channel; the support seats are respectively fixed to the inner and outer sides of the feeding channel, and the surface of each support seat abuts against the material feeding plate; each material feeding plate passes through the guide holes into the feeding channel, and each material feeding plate is used to carry coal to form a coal slope; the fixed end of the adjusting components is fixedly connected to the side wall of the chute, and the movable end of the adjusting components is fixedly connected to the material feeding plate; during the coal feeding process, the adjusting components adjust the position of the material feeding plate in the chute to change the position of the coal slope on the material feeding plate.

[0005] The adjustment assembly includes an adjusting nut, a lead screw, a positioning nut, and a slider. The adjusting nut is located at one end of the lead screw, and the other end of the lead screw passes through the guide hole and enters the feed channel. The positioning nut is fixedly located on the side wall of the feed channel, and the positioning nut is threadedly connected to the lead screw. One side of the slider is movably located on the outer circumferential surface of the lead screw, and the other side of the slider is fixedly connected to the positive material plate.

[0006] Furthermore, the support base is fixedly installed on the inner and outer walls of the feeding channel to maintain the state of the positive material plate within the feeding channel.

[0007] Furthermore, the support seats located outside the feeding channel are symmetrically distributed about the positive material plate, and the support seats located inside the feeding channel are all located below the positive material plate.

[0008] Furthermore, the first surface of each support abuts against the positive material plate, and the second surface of each support is fixedly connected to the inner wall of the feeding channel or the outer wall of the feeding channel, and the first surface and the second surface of the support are perpendicular to each other.

[0009] Furthermore, the length of the positive material plate is greater than the length of the lead screw, and the length of the positive material plate entering the feeding channel is greater than the length of the positive material plate exiting the feeding channel.

[0010] Furthermore, the chute includes a first part, a second part, and a third part that are interconnected. The first part is connected to the storage bin, and the second part is inclinedly connected to the first part and the third part. The third part has guide holes on the side near the coal conveyor belt, and the first part and the third part are parallel to each other.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

[0015] It should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0016] Figure 1 This is a schematic diagram of a maintenance-free feed-generating auxiliary device for a coal conveying system according to an embodiment of the present invention. Figure 2 for Figure 1 A magnified structural diagram of point A in the middle.

[0017] Reference Figure 1 A maintenance-free material feeding auxiliary device for a coal conveying system according to an embodiment of this utility model includes: a chute 2, multiple support seats 3, two material feeding plates 4, and two sets of adjusting components 5. The chute 2 is located above the coal conveyor belt 1 and is connected to a storage bin 6. The chute 2 is equipped with a feeding channel 7 for conveying coal. (See reference...) Figure 2 The inner and outer walls of the feeding channel 7 are respectively provided with guide holes 71 and multiple support seats 3. Each positive material plate 4 enters the feeding channel 7 through the guide hole 71. Each support seat 3 is located on the inner and outer walls of the feeding channel 7, and each positive material plate 4 is located between the support seats 3 to maintain its position within the feeding channel 7. Each set of adjusting components 5 is matched with one positive material plate 4. The fixed end of each set of adjusting components 5 is fixedly connected to the surface of the feeding channel 7, and the movable end of each set of adjusting components 5 is fixedly connected to the positive material plate 4.

[0018] During the coal feeding process, coal that deviates from the center of the feed channel 7 will accumulate on the corresponding side of the positive material plate 4 to form a coal pile. After accumulating to a certain extent, the coal falling into the coal pile will descend onto the coal conveyor belt 1 along the inclined slope (i.e., coal slope) formed on the coal pile. Under the action of the positive material plate 4, the coal will be concentrated in the center of the feed channel 7 during the discharge process, thus keeping the coal in the center when it falls onto the coal conveyor belt, thereby preventing belt deviation.

[0019] Specifically, each adjustment assembly 5 includes: an adjusting nut 51, a lead screw 52, ​​a positioning nut 53, and a slider 54. The adjusting nut 51 and slider 54 are respectively located at both ends of the lead screw 52. The outer periphery of the positioning nut 53 is fixed to the outer wall of the feed channel 7, and the inner ring surface of the positioning nut 53 is threadedly connected to the lead screw 52. One end of the lead screw 52 enters the feed channel 7 through a guide hole 71. The adjusting nut 51 is located on the lead screw 52 at the outer end of the feed channel 7, and the slider 54 is located on the lead screw 52 at the inner end of the feed channel 7. Both the adjusting nut 51 and the slider 54 are threadedly connected to the lead screw 52, ​​and the surface of the slider 54 is fixedly connected to the positive material plate 4. By rotating the adjusting nut 51, the operator can drive the positive material plate 4 on the slider 54 to move within the feed channel 7, thereby changing the position of the coal slope on the positive material plate 4.

[0020] Further, in another embodiment, the length of the positive material plate 4 is greater than the length of the lead screw 52, ​​and the length of the positive material plate 4 entering the feed channel 7 is greater than the length of the positive material plate 4 outside the feed channel 7. Each support 3 is fixed to the inner sidewall and the outer sidewall of the feed channel 7, respectively, thereby supporting the positive material plate 4. On the outer side of the feed channel 7, the support 3 are symmetrically distributed about the positive material plate 4, and the support 3 are distributed along the width direction of the positive material plate 4, thereby confining the positive material plate 4 between the support 3. On the inner side of the feed channel 7, the support 3 are all located below the positive material plate 4 to support the stability of the positive material plate 4 within the feed channel 7. Preferably, the support 3 is generally triangular prism-shaped, and each support 3 has a first surface and a second surface that are perpendicular to each other. The first surface of each support 3 abuts against the positive material plate 4, and the second surface of each support 3 is fixedly connected to the inner sidewall or the outer sidewall of the feed channel 7, respectively. After a period of operation, the edge of the feed plate 4 will wear down. At this time, the depth of the feed plate 4 in the feed channel 7 can be changed by adjusting the positioning component 5. This allows the operator to adjust the feed plate 4 from outside the feed channel 7, which not only effectively avoids the risk of the feed plate 4 falling off due to inadequate inspection, but also reduces downtime for maintenance and improves production efficiency.

[0021] Furthermore, the chute 2 includes a first part 21, a second part 22, and a third part 23 that are interconnected. The first part 21 is fixedly connected to the storage bin 6. The second part 22 is inclinedly positioned between the first part 21 and the third part 23. The third part 23 is located above the coal conveyor belt 1, and a support base 3, an adjusting component 5, and a positive material plate 4 are respectively provided on the end of the third part 23 closest to the coal conveyor belt 1. During coal feeding, the inclined portion of the second part 22 initially diverts the coal to prevent the coal from landing near the sides of the third part 23. In the feed pipe, after the initial diversion by the second part 22, the coal still biased towards the sides of the third part 23 is carried by the positive material plate 4 for a second diversion.

[0022] In summary, this invention uses a positive feed plate to support coal, thereby forming a coal slope to control the landing point of the coal after it leaves the feed pipe. Operators can further adjust the landing point of the coal after leaving the feed pipe by changing the position of the coal slope on the positive feed plate using the adjustment component, thus concentrating the coal's landing point on the conveyor belt. Furthermore, this invention allows the adjustment component to change the position of the positive feed plate within the feed channel, enabling adjustments by personnel from outside the equipment. This avoids safety hazards such as the positive feed plate falling off or tearing the conveyor belt, and also avoids frequent start-ups and shutdowns or no-load operation due to replacing the positive feed plate.
