Detailed Implementation

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "lateral", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0020] It should be noted that the terms "horizontal" and "vertical" in this invention are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane". Example

[0021] Please refer to Figures 1 to 6 As shown, this embodiment provides a self-cleaning long-distance conveyor belt, comprising: a plurality of conveyor units, all of which are arranged linearly, each conveyor unit including a support frame 10 and a conveyor belt 11, the conveyor belt 11 being supported on the support frame by two drive rollers 12; a second component including a vibration mechanism, the vibration mechanism including a plurality of vibration rollers 20, the vibration rollers 20 periodically striking the surface of the conveyor belt 11 to cause the conveyor belt 11 to vibrate periodically; and a third component including a rinsing mechanism, the rinsing mechanism including a plurality of nozzles 30, the nozzles 30 pointing towards the surface of the conveyor belt 11.

[0022] This embodiment discloses a self-cleaning long-distance transport belt conveyor. It utilizes multiple linearly arranged transport units, each including a support frame 10 and a conveyor belt 11, to achieve long-distance transport. A vibration mechanism, comprising multiple vibrating rollers 20, periodically strikes the conveyor belt 11, causing it to vibrate periodically and thus breaking down any deposits adhering to it. Furthermore, a flushing mechanism, including multiple nozzles 30, is installed, pointing at the conveyor belt 11. Simultaneously with the vibration of the vibration mechanism, the nozzles continuously flush the conveyor belt 11, quickly cleaning away deposits from its surface. This ensures the conveyor belt's friction, reduces the risk of material spillage, lightens the conveyor belt's weight, lowers the drive load, and reduces the energy consumption of each transport unit. Through the combined effect of these features, this self-cleaning long-distance transport belt conveyor effectively solves the problems of reduced pulley friction, increased material spillage risk, increased drive load, and increased belt conveyor energy consumption caused by the adhesion of impurities during long-distance stone transport.

[0023] To further explain the specific structure of the vibrating roller 20, the vibrating roller 20 is rotatably connected to the support frame 10 via a rotating shaft 21. The cross-section of the vibrating roller 20 perpendicular to the rotating shaft 21 is cam-shaped. The rotating shaft 21 is coaxially fitted with worm gears 22. All the worm gears 22 are driven by a worm 23. The worm 23 is rotatably connected to the support frame 10. The worm 23 is driven by a motor 24. The motor 24 is fixedly connected to the support frame 10.

[0024] By setting the cross section of the vibrating roller 20 perpendicular to the rotating shaft 21 to be cam-shaped, its most protruding part will periodically contact and lift the conveyor belt 11 during the rotation of the rotating shaft 21, so as to form a periodic striking effect; by setting the motor 24, worm 23 and worm wheel 22, the motor 24 drives the worm 23 to rotate, which in turn drives the worm wheel 22 to rotate, thereby driving the rotating shaft 21 coaxially mounted with the worm 22 to rotate, thereby driving the vibrating roller 20 to rotate.

[0025] To further define the cam shape of the vibrating roller 20, the cross section of the vibrating roller 20 perpendicular to the rotating shaft 21 is elliptical, and the rotating shaft 21 passes through a focal point of the cross section of the vibrating roller 20.

[0026] The above settings allow the vibrating roller 20 to strike the conveyor belt 11 more smoothly, thus preventing strong vibrations from causing goods on the conveyor belt 11 to fall off.

[0027] To further enhance the ability of the vibrating roller 20 to fully cover the width direction of the conveyor belt 11, the axial direction of the vibrating roller 20 extends along the width direction of the conveyor belt 11, and the length of the vibrating roller 20 is slightly greater than the width of the conveyor belt 11.

[0028] In order to further improve the vibration frequency, vibration effect and vibration stability, and to ensure that the impurities accumulated on the conveyor belt 11 are loosened by vibration and to avoid unnecessary falling of goods on the conveyor belt 11, all the vibrating rollers 20 are arranged in parallel at intervals, and two adjacent vibrating rollers 20 are in different phases.

[0029] It should be further explained that the aforementioned phase specifically refers to the specific angle at which the cam rotates, or the angle between the line connecting its most prominent point and the axis and the horizontal line. For example, when the most prominent point is horizontally to the right and coincides with the horizontal line, it is 0°; when the most prominent point is vertically upward and perpendicular to the horizontal line, it is 90°. Simply put, the angles of two adjacent vibrating rollers 20 are different, for example, one is 0° and the other is 90°.

[0030] In order to further clean the impurities attached to the inner surface of the conveyor belt 11, the vibrating roller 20 is provided in the frame-shaped area formed by the conveyor belt 11, and the vibrating roller 20 periodically hits the inner surface of the upper section of the conveyor belt 11.

[0031] With the above settings, not only can the entire conveyor belt 11 be vibrated and cleaned, but it can also directly contact and strike the inner surface of the conveyor belt 11, thereby further preventing impurities from adhering to the inner surface of the conveyor belt 11, which would reduce the friction between it and the drive roller 12.

[0032] To further ensure the levelness of the conveyor belt 11 and to further prevent the conveyor belt 11 from shaking due to the continuous impact of the vibrating roller 20, the support frame 10 is provided with multiple support rollers 13. The support rollers 13 are located in the frame-shaped area formed by the conveyor belt 11, and the support rollers 13 are in contact with the inner surface of the upper section of the conveyor belt 11.

[0033] With the above settings, the conveyor belt 11, after being struck upward by the vibrating roller 20, can be immediately supported and positioned by the support roller 13 after falling, preventing it from swinging downward excessively, thereby effectively improving the stability of the conveyor belt 11 during operation and avoiding unnecessary falling of the goods transported on it.

[0034] To further explain the specific structure of the rinsing mechanism, the rinsing mechanism includes a main water pipe 31 and multiple rinsing water pipes 32; the main water pipe 31 is horizontally arranged on the support frame 10 and extends linearly, one end of the main water pipe 31 is connected to a water source, and the other end is closed; all the rinsing water pipes 32 extend along the width direction of the conveyor belt 11 and are all connected to the main water pipe 31 through a water supply pipe 34, and the nozzle 30 is provided on the rinsing water pipe 32; the rinsing water pipe 32 is equipped with a water valve 33.

[0035] With the above setup, water is continuously supplied through the main water pipe 31, and then the water introduced from the main water pipe 31 is supplied to each connected flushing water pipe 32 through the water supply pipe 34. Then, the nozzles 30 installed on the flushing water pipes 32 spray water onto the surface of the conveyor belt 11 to wash away impurities subjected to vibration, thereby ensuring the cleanliness of the conveyor belt 11. By setting the flushing water pipes 32 to extend along the width of the conveyor belt 11, the nozzles 30 can fully cover the entire surface of the conveyor belt 11 to ensure the flushing effect.

[0036] To further improve the rinsing effect, each rinsing water pipe 32 is provided with a plurality of nozzles 30 evenly spaced along the axial direction; the nozzles 30 are inclined so as to form an acute angle with the surface of the conveyor belt 11, and all the nozzles 30 on each rinsing water pipe 32 are inclined in the same direction; the rinsing water pipe 32 includes at least two pipes, and the nozzles 30 on at least two rinsing water pipes 32 are symmetrically arranged in the inclination direction.

[0037] With the above configuration, the conveyor belt 11 is subjected to water flow from the nozzles 30 at two different angles in sequence, which further improves the rinsing effect. The inclined nozzles 30 can make the sprayed water flow form an acute angle with the conveyor belt 11, giving the impurities attached to the conveyor belt 11 a horizontal component force, so that they overcome the friction with the surface of the conveyor belt 11 and are separated from the surface of the conveyor belt 11, thereby further improving the rinsing effect.

[0038] To prevent the rinsing water from excessively affecting the various electrical control components involved in the conveyor belt 11, the rinsing water pipe 32 is located directly below the conveyor belt 11, and the nozzle 30 points to the outer surface of the section of the conveyor belt 11 located below it.

[0039] With the above configuration, firstly, only the bottom section of the conveyor belt 11 is rinsed, and the rinsed water falls directly to the ground (or into a water collection tank on the ground), instead of being carried by the conveyor belt 11 in large quantities to the upper sections, or even through electrically controlled components such as the conveyor roller 12, thus improving safety; secondly, rinsing the bottom section mainly targets the outer surface of the conveyor belt 11, i.e. the side covered with a large amount of impurities. The rinsed impurities can fall directly to the ground (or into a water collection tank on the ground) under the action of gravity and water flow, instead of falling to other sections of the conveyor belt 11 (for example, if the top section is rinsed, the impurities and water will fall to the inner surface of the lower section), thus avoiding secondary contamination.

[0040] When using the aforementioned self-cleaning long-distance conveyor belt, the number of corresponding transport units is selected according to the length to be transported. Then, the transport units are arranged linearly along the transport path, so that the gap at the end of the conveyor belt 11 of adjacent transport units is smaller than the size of the goods to be transported. Then, the conveyor belt 11 is started for transport. During the process, all motors 24 are turned on, causing all worm gears 23 to rotate, which in turn drives all worm wheels 22 to rotate, which in turn drives all rotating shafts 21 to rotate, which in turn drives all vibrating rollers 21 to rotate, periodically striking the corresponding conveyor belt 11, causing the impurities attached to the conveyor belt 11 to loosen and fall off. At the same time, the flushing mechanism is turned on, all water valves 33 are turned on, and water introduced from the main water pipe 31 through the nozzles 30 is introduced into the corresponding flushing water pipes 32 through all water supply pipes 34. The water is then sprayed out from the corresponding nozzles 30 onto the surface of the conveyor belt 11, so that the surface of the conveyor belt 11 is continuously flushed by the sprayed water flow, thereby thoroughly cleaning the impurities attached to the surface of the conveyor belt 11.

[0041] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
