Description

TECHNICAL FIELD

[0001] The present application relates to the field of conveying equipment, in particular to a coal unmanned mining conveying equipment. BACKGROUND

[0002] The conveying equipment is a kind of mechanical equipment that transports materials in a continuous manner by friction drive, and the conveying equipment used in mining industry generally adopts two types of conveying equipment, namely main inclined large angle belt conveyor and rope frame hanging belt conveyor. Among them, the main inclined large angle belt conveyor uses the roller group arranged at an angle to support the belt and assist the conveying process of the belt. However, due to the long-term dark and humid environment in the mine, the damp belt will reduce the friction between the material and the belt, further causing the problem of low conveying efficiency of the conveying belt. At the same time, in the process of transporting coal mine by the main inclined large angle belt conveyor, although the roller group can assist the support of the conveying belt and effectively improve the carrying capacity of the conveying belt, the area of the conveying belt supported by the roller group is in a convex structure, which causes the material to be hindered when being conveyed to the area, resulting in sliding (relative movement of the material on the conveying belt).

[0003] From the above, it can be seen that the prior art has obvious inconvenience and defects in actual use, so it is necessary to improve. SUMMARY

[0004] In view of the above defects, the purpose of the present application is to provide a coal unmanned mining conveying equipment, which can increase the friction between the conveying belt and the material by using a plurality of blocking protrusions arranged on the conveying belt, and further optimize the conveying effect of the conveying belt. The gap between the blocking protrusions can be changed by using an adjustable roller group, and the conveying effect of the conveying belt can be further adjusted.

[0005] In order to achieve the above purpose, the present application provides a coal unmanned mining conveying equipment, which comprises a conveying belt support, a roller group installed at a middle position, and a conveying belt installed on the conveying belt support and partially located on the roller group. A plurality of blocking protrusions are distributed on the conveying belt, and a predetermined gap is left between the plurality of blocking protrusions. When the bottom of the conveying belt is subjected to a local upward force, the gap between the plurality of blocking protrusions will be enlarged. The roller group comprises a horizontal roller whose axis is perpendicular to the conveying direction of the conveying belt, and an inclined roller located on both sides of the horizontal roller and hinged to the end of the horizontal roller. The end of the inclined roller is hinged to the conveying belt support. The horizontal roller is driven by a longitudinal adjustment structure and can move in the vertical direction.

[0006] According to the coal unmanned mining conveying equipment of the present application, the two ends of the conveying belt support are hinged with movable frames, and the ends of the movable frames are hinged with the inclined rollers.

[0007] The longitudinal adjusting structure comprises a moving frame connected with the horizontal roller, a rack installed at the bottom end of the moving frame, and a gear structure installed on the conveyor belt support and engaged with the rack.

[0008] The moving frame bottom end is installed with a longitudinal positioning block for vertical positioning, and the conveyor belt support is provided with an embedded groove cooperating with the longitudinal positioning block.

[0009] The movable frame is in L-shaped structure.

[0010] The inclined roller comprises a roller shaft hingedly connected with the horizontal roller and the conveyor belt support and a roller sleeve sleeved on the roller shaft.

[0011] The coal unmanned mining and transporting equipment comprises a conveyor belt support, a roller set installed at a middle position, and a conveyor belt installed on the conveyor belt support and partially located on the roller set. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples, and it should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0019] Referring to Figure 1 , Figure 2 and Figure 3 , the present application provides a coal unmanned mining and transporting equipment, which comprises a conveyor support 1, a toll roller group 2 installed at a middle position and a conveyor belt 3 installed on the conveyor support 1 and partially located on the toll roller group 2; the conveyor support 1 is installed on a conveyor frame body at equal intervals, and the conveyor belt 3 is supported by the toll roller group 2 to ensure good material carrying effect during conveying.

[0020] The conveyor belt 3 is provided with a plurality of blocking protrusions 31, which can be in the shape of a square or a strip, and a predetermined gap is left between the plurality of blocking protrusions 31. In the normal state (the bottom of the conveyor belt 3 is not under force), the predetermined gap is 1-2 mm; when the bottom of the conveyor belt 3 is subjected to a local upward force (indicating that the conveyor belt 3 enters the supporting area of the toll roller group, so that the conveyor belt 3 enters an outward convex state), the gap between the plurality of blocking protrusions 31 will be enlarged, and the size of the gap changes with the size of the upward force. The greater the upward force, the greater the gap, and the friction between the material and the conveyor belt is increased by the increased gap between the plurality of blocking protrusions 31, further increasing the conveying effect of the conveyor belt 3.

[0021] The supporting roller group 2 comprises horizontal rollers 21 whose axes are perpendicular to the conveying direction of the conveying belt 3, and oblique rollers 22 which are located on both sides of the horizontal rollers 21 and are hingedly connected to the ends of the horizontal rollers 21, the included angle between the horizontal rollers 21 and the oblique rollers 22 is 30-60°, the horizontal rollers 21 mainly provide supporting effect, and the oblique rollers 22 not only provide auxiliary supporting effect but also provide material gathering effect (the material is placed in the middle position of the conveying belt 3 during conveying to avoid falling off the conveying belt 3) to the material placed on the conveying belt 3; the ends of the oblique rollers 22 are hingedly connected to the conveying belt support 1, and the oblique rollers 22 can rotate relative to the horizontal rollers 21 in the same vertical plane about the hinged shaft; the horizontal rollers 21 are driven by a longitudinal adjusting structure and can move in the vertical direction. When the height of the horizontal rollers 21 is adjusted, the oblique rollers 22 are also driven to adjust the angle, so that the included angle between the two oblique rollers 22 changes. When the included angle between the two oblique rollers 22 changes, different pressing force effects are generated on the conveying belt 3.

[0022] The oblique roller 22 comprises a roller shaft 71 hingedly connected to the horizontal roller 21 and the conveying belt support 1, and a roller sleeve 72 sleeved on the roller shaft 71. The roller sleeve 72 slides relative to the roller shaft 71; through the above structure, the transmission effect of the oblique roller 22 is optimized by using the rolling roller sleeve 72.

[0023] The conveying belt support 1 is hingedly connected with a movable frame 4 at both ends; the end of the movable frame 4 is hingedly connected to the oblique roller 22, and the angle of the oblique roller 22 is adjusted by the up-down effect of the horizontal roller 21 through the transition cooperation of the movable frame 4. In this embodiment, the movable frame 4 is in L-shaped structure, and other structures can also be provided according to needs.

[0024] The longitudinal adjusting structure comprises a moving frame 51 connected to the horizontal roller 21, a rack 52 installed at the bottom end of the moving frame 51, and a gear structure 53 installed on the conveying belt support 1 and engaged with the rack 52. When the height of the horizontal roller 21 is adjusted by the longitudinal adjusting structure, the gear structure 53 is driven to rotate (the gear structure 53 can be connected to an external driving shaft, and the driving of the gear structure 53 is realized by rotating the driving shaft), the gear structure 53 is engaged with the rack 52 to drive the horizontal roller 21 to adjust the up-down position.

[0025] Referring to Figure 4 and Figure 5Preferably, the mobile frame 51 of the present application is provided with longitudinal positioning blocks 61 at the bottom end for vertical positioning, and the conveying belt support 1 is provided with embedding grooves 62 for cooperating with the longitudinal positioning blocks 61; and the rack 52 is installed on the longitudinal positioning blocks 61. When the horizontal roller 21 moves up and down, the embedding grooves 62 and the longitudinal positioning blocks 61 cooperate (the longitudinal positioning blocks 61 slide in the embedding grooves 62) to ensure the positioning of the movement of the horizontal roller 21, avoiding dislocation.

[0026] When the environment in the mine is excessively humid, the longitudinal adjustment structure is adjusted to drive the horizontal roller 21 to move downward, which drives the inclined roller 22 to change the angle (the included angle between the two inclined rollers 22 on both sides becomes smaller), further increasing the local pressing force of the inclined roller 22 on the conveying belt 3. When the bottom of the conveying belt 3 is subjected to an increased force, the gap between the blocking protrusions 31 on the working surface is increased, further increasing the friction between the conveying belt 3 and the material, and optimizing the conveying effect of the conveying belt 3.

[0027] When the environment in the mine is relatively dry, the longitudinal adjustment structure is adjusted to drive the horizontal roller 21 to move upward, which drives the inclined roller 22 to change the angle (the included angle between the two inclined rollers 22 on both sides becomes larger), further reducing the local pressing force of the inclined roller 22 on the conveying belt 3 (according to the adjustment of the state of the conveying belt 3 according to the humidity change in the mine, when in a relatively dry environment, the friction is sufficient, so the deformation of the conveying belt 3 can be appropriately reduced to increase its service life), when the bottom of the conveying belt 3 is subjected to an increased force, the gap between the blocking protrusions 31 on the working surface is increased, further increasing the friction between the conveying belt 3 and the material, and optimizing the conveying effect of the conveying belt 3.

[0028] In summary, the present application provides a kind of coal unmanned mining and transporting equipment, including conveyor belt support, the roller group installed in middle position and the conveyor belt installed on the conveyor belt support and partially located on the roller group;The conveyor belt support is installed on the conveyor belt total frame body at equal intervals, and the conveyor belt is supported by the roller group, to ensure that it has good material carrying effect during conveying.The conveyor belt is distributed with several blocking protrusions, which can be square or strip-shaped, and there is a predetermined gap between several blocking protrusions, in normal state (the bottom of the conveyor belt is not forced), and when the bottom of the conveyor belt is subjected to local upward force (indicating that the conveyor belt enters the supporting area of the roller group, so that the conveyor belt enters the convex state), the gap between several blocking protrusions will be enlarged, and the size of the gap changes with the size of the top force, the larger the top force, the larger the gap, the friction between the material and the conveyor belt is increased by the gap between the blocking protrusions, and the conveying effect of the conveyor belt is further increased.The present application increases the friction between the conveyor belt and the material by setting several blocking protrusions on the conveyor belt, and further optimizes the conveying effect of the conveyor belt;The gap between the blocking protrusions is changed by using adjustable roller group, to further adjust the conveying effect of the conveyor belt.

[0029] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should belong to the protection scope of the claims attached to the present application.
