Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology, specifically a coal conveying device with adjustable feeding direction. Background Technology

[0002] Coal mining is a complex and systematic process, with its main steps including exploration, design, development, mining, and transportation. After mining is completed, the coal needs to be transported out of the mine for processing and sale. The main transportation methods include railway transportation, road transportation, and conveyor belts. With the continuous development of the coal mining industry, conveyor belts for coal transportation have also been gradually upgraded.

[0003] For example, the patent with authorization announcement number CN221115729U discloses a coal mine conveying device. A scraper is provided at the bottom of one end of the conveyor belt to scrape off most of the adhering coal. By setting a self-starting water spraying mechanism, the adhesion of strongly adhering coal can be reduced, making it easier for the scraper to scrape off the firmly adhered coal. This prevents the coal from sticking to the conveyor belt during the conveying process, thus ensuring the amount of coal conveyed and avoiding the situation where the adhering coal increases the power consumption of the conveying mechanism. The overall effect is good, but there are still some shortcomings.

[0004] The aforementioned patents and some existing coal conveyor belts share a common shortcoming: the length of the conveying device is not adjustable. For longer conveying distances, multiple conveyor belts can be connected by docking. However, for shorter conveying distances or when space is limited, fixed-length conveyor belts cannot adapt to such situations. Furthermore, some conveyor belts rely heavily on manual pushing and adjustment when adjusting their conveying orientation, which increases the labor intensity of the workers. Utility Model Content

[0005] To address the aforementioned issues, this application provides a coal conveying device with adjustable feeding direction, which solves the problem that the length of the conveying device is not adjustable. For longer conveying distances, multiple conveyor belts can be connected by docking. However, for shorter conveying distances or when space is limited, fixed-length conveyor belts cannot adapt to such situations. Moreover, when adjusting the conveying direction of some conveyor belts, manual pushing and adjustment are often required, which increases the labor intensity of the workers.

[0006] A coal conveying device with adjustable feeding direction includes a belt, two rotating shafts rotatably mounted on the inner side of the belt, a drive motor fixedly mounted at the end of one rotating shaft, an adjusting shaft slidably mounted on the inner side of the belt, sliders fixedly mounted at both ends of the adjusting shaft, springs fixedly mounted on the top of the sliders, and an electric telescopic rod for adjusting the distance between the two rotating shafts mounted on the outer side of the rotating shaft.

[0007] Furthermore, two mounting brackets are symmetrically installed on the outer side of the belt. One end of the rotating shaft of one bracket is rotatably connected to the mounting bracket, and the other end rotates through the mounting bracket and is fixedly connected to the drive motor.

[0008] Furthermore, the bottom of the two mounting brackets near the ends is fixedly mounted with the output end of the adjusting motor, the bottom of the adjusting motor is fixedly mounted with a fixed base, and the bottom of the two mounting brackets away from the adjusting motor is fixedly mounted with multiple casters.

[0009] Furthermore, a limiting post is slidably installed through the middle of the slider, the limiting post is fixedly installed inside the mounting frame, a spring is fixedly installed between the top of the slider and the inner side of the mounting frame, and the spring is movably installed around the limiting post.

[0010] Furthermore, a sliding plate is slidably mounted on the outer side of the mounting frame, a limit strip is fixedly mounted on the end of the sliding plate, a limit block is slidably mounted through the outer side of the limit strip, and the limit block is fixedly mounted on the outer side of the mounting frame;

[0011] The telescopic end of the electric telescopic pole is fixedly connected to a sliding plate, and the electric telescopic pole is fixedly installed on the outside of the mounting frame.

[0012] Furthermore, a limit shaft is installed between each of the two rotating shafts and the adjusting shaft. The limit shaft is slidably installed on the outer side of the bottom of the belt, and the ends of the limit shaft are rotatably installed on the inner side of the mounting bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) The coal conveying device with adjustable feeding position described in this utility model uses an electric telescopic rod to change the distance between the sliding plate, the rotating shaft and the drive motor, thereby changing the conveying distance of the belt. The conveying distance of the belt can be changed according to the specific use environment, making it applicable to a wider range of working environments and enhancing its practicality.

[0015] (2) The coal conveying device with adjustable feeding position described in this utility model can drive the belt to rotate by adjusting the motor, thereby adjusting the conveying angle of the belt. No staff intervention is required, reducing labor intensity. Moreover, the adjustment angle can be controlled according to the program setting, making it more accurate to connect with other conveyor belts or receiving equipment, and more suitable for standardized operation scenarios.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0023] like Figures 1-4 As shown, this utility model embodiment provides a coal conveying device with adjustable feeding direction, including a belt 4. Two rotating shafts 11 are rotatably installed inside the belt 4. A drive motor 5 is fixedly installed at the end of one rotating shaft 11 to drive the belt 4 to rotate. An adjusting shaft 13 is slidably installed inside the belt 4. A slider 14 is fixedly installed at both ends of the adjusting shaft 13. A spring 16 is fixedly installed on the top of the slider 14 to keep the belt 4 taut at all times. An electric telescopic rod 9 is installed on the outside of the rotating shaft 11 to adjust the distance between the two rotating shafts 11, thereby adjusting the conveying distance of the belt 4.

[0024] In this embodiment, the conveying distance of belt 4 is extended. When the operator starts the electric telescopic rod 9, the telescopic end of the electric telescopic rod 9 extends, which drives the rotating shaft 11 away from the drive motor 5, thereby extending the conveying distance of belt 4. At the same time, belt 4 pulls the adjusting shaft 13 and slider 14 upward, and spring 16 is compressed, so that belt 4 is taut and can operate normally.

[0025] When the conveying distance of belt 4 is shortened, the operator starts the electric telescopic rod 9. The telescopic end of the electric telescopic rod 9 is shortened, which drives the rotating shaft 11 to approach the drive motor 5, thus shortening the conveying distance of belt 4. At the same time, the elastic force of spring 16 pushes the adjusting shaft 13 and slider 14 to move down, making belt 4 taut and allowing it to work normally. Belt 4 can change the conveying distance according to the specific use environment, making it applicable to a wider range of working environments and enhancing its practicality.

[0026] Specifically, two mounting brackets 3 are symmetrically installed on the outer side of the belt 4. One end of the rotating shaft 11 is rotatably connected to the mounting bracket 3, and the other end rotatably passes through the mounting bracket 3 and is fixedly connected to the drive motor 5.

[0027] Specifically, the output end of the adjusting motor 2 is fixedly installed on the bottom of the two mounting brackets 3 near the end. The bottom of the adjusting motor 2 is fixedly installed with a fixed base 1. The fixed base 1 can be fixed to the ground or the outside of other equipment by bolts. Multiple casters 10 are fixedly installed on the bottom of the two mounting brackets 3 away from the adjusting motor 2 to reduce the rotation resistance of the mounting bracket 3 and facilitate the rotation of the mounting bracket 3.

[0028] In this embodiment, the conveying angle of belt 4 is adjusted by the operator starting the adjusting motor 2, which drives belt 4 to rotate, thereby adjusting the conveying angle of belt 4. No operator intervention is required, reducing labor intensity. Moreover, the adjustment angle can be controlled according to the program settings, making the docking with other conveyor belts or receiving equipment more accurate and more suitable for standardized operation scenarios.

[0029] Specifically, a limiting post 15 is slidably installed through the middle of the slider 14 to limit the movement trajectory of the slider 14. The limiting post 15 is fixedly installed inside the mounting bracket 3, and the spring 16 is fixedly installed between the top of the slider 14 and the inner side of the mounting bracket 3. The spring 16 is movably installed around the limiting post 15.

[0030] Specifically, a sliding plate 6 is slidably installed on the outside of the mounting frame 3, a limit strip 7 is fixedly installed at the end of the sliding plate 6, and a limit block 8 is slidably installed through the outside of the limit strip 7. The limit strip 7 and the limit block 8 are used to limit the movement trajectory of the sliding plate 6 and the rotating shaft 11. The limit block 8 is fixedly installed on the outside of the mounting frame 3. The telescopic end of the electric telescopic rod 9 is fixedly connected to one of the sliding plates 6. The electric telescopic rod 9 is fixedly installed on the outside of the mounting frame 3.

[0031] In this embodiment, when the telescopic end of the electric telescopic rod 9 extends, it drives the sliding plate 6 and the rotating shaft 11 away from the drive motor 5. When the conveying distance of the belt 4 shortens, it drives the sliding plate 6 and the rotating shaft 11 closer to the drive motor 5.

[0032] Specifically, a limiting shaft 12 is installed between each of the two rotating shafts 11 and the adjusting shaft 13. The limiting shaft 12 is slidably installed on the outer side of the bottom of the belt 4, and the ends of the limiting shaft 12 are rotatably installed on the inner side of the mounting bracket 3.

[0033] In this embodiment, the limiting shaft 12 is used to ensure that the wrap angle between the belt 4 and the rotating shaft 11 is within a reasonable range, so as to ensure that the drive motor 5 can drive the belt 4 to rotate.

[0034] Specific working methods:

[0035] When the conveying distance of belt 4 is extended, the operator starts the electric telescopic rod 9. The telescopic end of the electric telescopic rod 9 extends, which moves the sliding plate 6 and the rotating shaft 11 away from the drive motor 5, thus extending the conveying distance of belt 4. At the same time, belt 4 pulls the adjusting shaft 13 and the slider 14 upward, and the spring 16 is compressed, making belt 4 taut and able to operate normally.

[0036] When the conveying distance of belt 4 is shortened, the operator starts the electric telescopic rod 9. The telescopic end of the electric telescopic rod 9 is shortened, which drives the sliding plate 6 and the rotating shaft 11 to move closer to the drive motor 5, thus shortening the conveying distance of belt 4. At the same time, the elastic force of the spring 16 pushes the adjusting shaft 13 and the slider 14 to move down, making belt 4 taut and allowing it to work normally. The conveying distance of belt 4 can be changed according to the specific use environment, making it applicable to a wider range of working environments and enhancing its practicality.

[0037] To adjust the conveying angle of belt 4, the operator starts the adjusting motor 2, which drives belt 4 to rotate, thereby adjusting the conveying angle of belt 4. No operator intervention is required, reducing labor intensity. Moreover, the adjustment angle can be controlled according to the program settings, making it more accurate to connect with other conveyor belts or receiving equipment, and more suitable for standardized operation scenarios.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
