Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt technology, and in particular relates to a coal mine conveyor belt with adjustable conveying length. Background Technology

[0002] Conveyor belts, also known as conveyor belts, are the transmission medium in conveyor belt systems. A conveyor belt system is a type of transmission system that includes two or more pulleys with a conveyor belt on them. The pulleys can rotate without restriction, allowing the conveyor belt to move. One or more pulleys are powered to drive the conveyor belt, carrying the material it carries. Conveyor belts are also used in coal mine transportation. Traditional coal mine conveyor belts require a frame, drive rollers, and motor for compatibility, and are mostly fixed structures, meaning the conveying length is fixed and cannot be quickly extended according to on-site needs. This directly affects the normal transport of coal, greatly reducing the overall efficiency of the equipment and exhibiting significant limitations. Utility Model Content

[0023] Example: A coal mine conveyor belt with adjustable conveying length is applied to a first frame 1 and a second frame 2. It also includes a conveyor belt body 11 mounted on the first frame 1 and the second frame 2. Two sets of support legs on the first frame 1 are equipped with casters at their bottoms. A controller is mounted on the left support leg of the first frame 1. Multiple sets of first drive rollers 3 are rotatably mounted on the first frame 1 and the second frame 2 in a left-right direction. Second drive rollers 5 are rotatably mounted on the left support legs of both the first frame 1 and the second frame 2. The first drive rollers 3 and the second drive rollers 5 are in transmission cooperation with the conveyor belt body 11. A motor 4, whose output shaft end is fixed to one set of first drive rollers 3, is fixed to the left side of the front of the first frame 1 via a side frame. An auxiliary extension assembly for use with the conveyor belt body 11 is provided on the first frame 1 and the second frame 2. The auxiliary extension assembly includes a support leg fixed to the left side of the second frame 2. An auxiliary cylinder 12 is located on the side of the leg. The piston rod of the auxiliary cylinder 12 is fixed with a reinforcing pusher 15. A drive side plate 13 is rotatably mounted on the bottom of the front of the left support leg of the second frame 2. The drive side plate 13 has a drive groove 26 that works with the reinforcing pusher 15. A positioning pull rod 14 with one end inserted into the drive groove 26 is fixed on the front of the first frame 1. An auxiliary slide 6 is slidably mounted on the right support leg of the second frame 2. Multiple sets of third transmission rollers 7 that work with the conveyor belt body 11 are mounted on the auxiliary slide 6 in the left and right directions. Drive cylinders 8 are embedded on both the front and back of the auxiliary slide 6. The piston rod of the drive cylinder 8 is fixed with a locking block 9. Anti-shifting holes 10 that engage with the locking block 9 are symmetrically opened on the front and back of the right support leg of the second frame 2. A support structure that works with the conveyor belt body 11 is provided between the first frame 1 and the second frame 2.

[0024] Specifically, this utility model, by setting up an auxiliary extension component, utilizes an auxiliary cylinder 12, a drive side plate 13, a positioning pull rod 14, a reinforcing push frame 15, and a drive groove 26 to quickly change the distance between the first frame 1 and the second frame 2, thereby simultaneously changing the position of the auxiliary slide 6. This allows for a rapid change in the overall shape of the conveyor belt body 11. Furthermore, the design of the drive cylinder 8, auxiliary slide 6, third transmission roller 7, locking block 9, and anti-shift hole 10 allows for rapid positioning of the auxiliary slide 6 after the position change, ensuring that the conveyor belt body 11 remains at an appropriate tension. This transforms the conveyor belt body 11 from a "7"-shaped structure to a straight structure, thereby expanding the conveyor belt body 11's coal conveying length as needed for better coal transport. This improves the usability and adaptability of the conveyor belt body 11 while simultaneously reducing limitations.

[0025] The support structure includes insert plates 17 inserted into the front and back sides of the first frame 1 and the second frame 2 on the side close to each other. A T-shaped card plate 18 with its top attached to the conveyor belt body 11 is inserted into the side of the insert plates 17 close to each other. A back frame 23 is symmetrically slidably arranged on the back of the T-shaped card plate 18. A sleeve 24 for inserting one end of the back frame 23 is fixed on the back of both the first frame 1 and the second frame 2. A back plate 21 is fixed at the center of the back of the T-shaped card plate 18. A spring 22 is fixed between the back plate 21 and the back frame 23.

[0026] Specifically, the design of the support structure utilizes spring 22, back frame 23, back plate 21, and insert sleeve 24 to form a locking structure for T-shaped clamp plate 18 and insert plate 17, so as to quickly fix insert plate 17 and T-shaped clamp plate 18 in the extension area between the first frame 1 and the second frame 2, so as to provide auxiliary support and auxiliary limiting for the conveyor belt body 11, thereby improving the stability of the conveyor belt body 11 during transmission.

[0027] A U-shaped card holder 25 is inserted into the back plate 17, and a limiting groove is provided on the back frame 23 and the back plate 21 to cooperate with the U-shaped card holder 25.

[0028] Specifically, the design of the U-shaped card holder 25 and the limiting groove allows the back frame 23 to be positioned when the T-shaped card plate 18 is inserted into the insert plate 17, so that the two sets of back frames 23 can be retracted to the back of the T-shaped card plate 18 to avoid affecting the normal insertion of the T-shaped card plate 18.

[0029] Each set of insert plates 17 has a slide bar 19 fixed on both sides. The first frame 1 and the second frame 2 are provided with a first slide rail 20 that slides with the slide bar 19 on the side that is close to each other. The back of the T-shaped plate 18 is symmetrically provided with a second slide rail that slides with the back frame 23.

[0030] Specifically, the slide bar 19 and the first slide rail 20 are engaged to pre-position the insert plate 17 so that the insert plate 17 can be quickly positioned later. The design of the second slide rail can limit the sliding of the back frame 23, improving its stability during movement, so that the back frame 23 can be inserted into the insert sleeve 24 without obstruction.

[0031] Both the front and back of the first frame 1 and the second frame 2 are provided with drainage channels that communicate with the first slide rail 20.

[0032] Specifically, the design of the drain trough allows users to clean up dirt and impurities that fall into the first slide rail 20, preventing them from affecting the normal insertion of the slide bar 19.

[0033] Fixed plates 16 are symmetrically inserted into the right support legs of the first frame 1, and one end of the fixed plate 16 is fixed to the left support leg of the second frame 2.

[0034] Specifically, the design of the fixed plate 16 can slide and limit the first frame 1, preventing it from shifting when moving and improving the overall stability of the device during expansion.

[0035] In use: In the initial state, the locking block 9 is aligned with the lower anti-shift hole 10, and the entire conveyor belt body 11 is in a "7" shape. When it is necessary to extend the conveying length of the conveyor belt body 11, the user activates the drive cylinder 8 through the controller, which can disengage the locking block 9 from the lower anti-shift hole 10, releasing the locking state of the auxiliary slide 6. At this time, the user activates the auxiliary cylinder 12 through the controller, which can change the position of the reinforcing pusher 15. With the assistance of the drive groove 26, the flipping angle of the drive side plate 13 can be controlled. At the same time, with the assistance of the positioning pull rod 14, the first frame 1 can be driven to move synchronously to the left. At this time, under the action of the conveyor belt body 11, the auxiliary slide 6 can be pulled to move synchronously upward. When the right support leg of the first frame 1 contacts the protruding end of the fixed plate 16, the locking block 9 moves to the upper anti-shift hole 10. At this time, the drive cylinder 8 drives the locking block 9 to move to the upper anti-shift hole 10. Block 9 engages with the upper anti-slip hole 10, thereby positioning the auxiliary carriage 6. At this time, the conveyor belt body 11 changes from a "7"-shaped structure to a straight structure, thus expanding the conveying length of the conveyor belt body 11 for coal as needed. The user can insert the insert plate 17 between the first frame 1 and the second frame 2 by inserting the slide bar 19 into the first slide rail 20. Then, the user inserts the T-shaped clamp 18 through the insert plate 17 with its top in contact with the conveyor belt body 11 to support the conveyor belt body 11 and prevent the coal from collapsing when it is conveyed to this point. Then, the user moves the U-shaped clamp 25 to release the limiting state of the back frame 23. At this time, the elastic rebound of the spring 22 can drive the back frame 23 to move outward and insert it into the insert sleeve 24 to position the insert plate 17 and the T-shaped clamp 18, thereby providing auxiliary support for the conveyor belt body 11 for better coal conveying.

[0036] In summary, this coal mine conveyor belt with adjustable conveying length can quickly change the overall shape of the conveyor belt body 11 by setting auxiliary extension components, transforming the conveyor belt body 11 from a "7"-shaped structure to a straight structure. This allows for extending the conveying length of the conveyor belt body 11 for coal as needed, thus improving the conveying efficiency and adaptability of the conveyor belt body 11 while simultaneously reducing limitations.

[0037] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
