Furthermore, coal conveying pipes typically consist of multiple pipes joined together, and the joints often have poor sealing properties. If coal dust escapes, this not only wastes energy but also causes air pollution. Summary of the Invention

Of course, the drawings described below are only a part of the embodiments of the present invention, and those skilled in the art can devise other drawings based on these drawings without any creative efforts. [Figure 1] FIG. 1 is an overall schematic diagram of the present invention. [Figure 2] FIG. 2 is a cross-sectional view of the present invention. [Figure 3] 1 is a schematic diagram of a sealing assembly of the present invention; [Figure 4] 1 is a schematic diagram of a conveying mechanism according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below with reference to the drawings in the specification.

[0022] Although the following description sets forth numerous specific details to provide a thorough understanding of the present invention, the present invention may be embodied in other forms different from those described herein, and those skilled in the art will be able to make similar applications without violating the spirit and scope of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

[0023] As used herein, the term "one embodiment" or "embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they mutually exclusive of other embodiments, either singly or in the alternative.

[0024] Example 1 1 and 2, a first embodiment of the present invention provides a cleaning mechanism, which includes: The cleaning member 100 includes a coal conveying pipe 101, a sealing plate 102 fixedly connected to the outside of the coal conveying pipe 101, a power assembly 103 disposed outside the sealing plate 102, a driven assembly 104 disposed outside the power assembly 103, a fixed assembly 105 disposed inside the coal conveying pipe 101, a sealing assembly 106 disposed inside the coal conveying pipe 101, and a supply assembly 107 disposed outside the coal conveying pipe 101.

[0025] Specifically, the power assembly 103 includes a motor 103a disposed outside the sealing plate 102 and an output shaft 103b disposed outside the motor 103a.

[0026] Furthermore, the driven assembly 104 includes a driven shaft 104a fixedly connected to the outside of the output shaft 103b, and a vane 104b fixedly connected to the outside of the driven shaft 104a.

[0027] Here, the driven assembly 104 further includes a connecting line 104c fixedly connected to the outside of the driven shaft 104a, and a rubber ball 104d fixedly connected to the outside of the connecting line 104c.

[0028] Preferably, the fixing assembly 105 includes a connection block 105a fixedly connected to the inside of the coal conveying pipe 101, a sleeve 105b fixedly connected to the outside of the connection block 105a, and a notch 105c opened inside the sleeve 105b.

[0029] When cleaning is required during use, the worker starts the motor 103a, which then drives the driven shaft 104a to rotate via the output shaft 103b, and under the action of centrifugal force, the driven shaft 104a drives the rubber ball 104d to rotate via the connecting wire 104c.

[0030] Due to the obstruction of the sleeve 105b, the rubber ball 104d cannot collide with the inner wall of the coal conveying pipe 101 while rotating. When the connecting line 104c rotates inside the notch 105c, the connecting line 104c exposed from the sleeve 105b becomes longer, allowing the rubber ball 104d to collide with the inner wall of the coal conveying pipe 101. Under the action of the collision, the coal conveying pipe 101 vibrates, and the coal slag adhering to the inner wall of the coal conveying pipe 101 is shaken off, thereby achieving the purpose of sweeping and cleaning the coal conveying pipe 101.

[0031] As described above, by combining the power assembly 103, the driven assembly 104 and the fixed assembly 105, when cleaning is required, the rubber ball 104d can be made to collide with the inner wall of the coal conveying pipe 101 to shake off the coal slag, thereby achieving the purpose of cleaning the coal conveying pipe 101.

[0032] Example 2 Referring to FIGS. 1 to 3, the second embodiment of the present invention is different from the previous embodiment in that the second embodiment includes a position limiting plate 106a slidably connected to the inside of the coal conveying pipe 101 and a spring 106b provided on the outside of the position limiting plate 106a; A sealing assembly 106 is provided, in which one end of a spring 106b is fixedly connected to the outside of the position limiting plate 106a and the other end of the spring 106b is fixedly connected to the inside of the coal conveying pipe 101.

[0033] Specifically, the sealing assembly 106 further includes a cylinder 106c fixedly connected to the outside of the position limiting plate 106a, a wind collecting plate 106d fixedly connected to the outside of the cylinder 106c, and a tapered surface 106e opened inside the cylinder 106c.

[0034] Furthermore, the supply assembly 107 includes a supply pipe 107a fixedly connected to the outside of the coal conveying pipe 101, and a flange 107b fixedly connected to the outside of the supply pipe 107a.

[0035] During use, in the cleaning process, in addition to the collision of the rubber ball 104d with the inner wall of the coal transport pipe 101, the rotation of the blade 104b is also utilized, and the blade 104b blows to move the cylinder 106c under the action of the air collecting plate 106d, thereby pressing the spring 106b, and while the cylinder 106c is moving, the coal slag on the inner wall of the coal transport pipe is scraped off via the tapered surface 106e.

[0036] Furthermore, when the cylinder 106c moves to the limit position, the supply pipe 107a is blocked, thereby avoiding the problem of fuel waste caused by the coal slag blown by the blades 104b spilling out of the supply pipe 107a.

[0037] As described above, by combining the power assembly 103, the driven assembly 104, the fixed assembly 105, the sealing assembly 106 and the supply assembly 107, the problem of thoroughly cleaning the coal slag adhering to the inner wall of the coal conveying pipe 101 can be solved by three directions: the collision of the rubber balls 104d, the blowing of the blades 104b, and the scraping by the cylinder 106c. In addition, by blocking the supply pipe 107a with the cylinder 106c, the spilling of the coal slag can be prevented, and the effect of fully utilizing the fuel can be achieved.

[0038] Example 3 Referring to Fig. 4, the third embodiment of the present invention is different from the previous embodiment in that it provides a coal conveying pipe. The coal conveying pipe includes: A cleaning mechanism; The coal transport pipe includes a connecting pipe that is thread-connected to the outside of the coal transport pipe, and a wrap member disposed on the outside of the connecting pipe.

[0039] Specifically, the wrap member 202 includes a seal strip 202a wrapped around the outside of the connecting pipe 201, and a connecting plate 202b fixedly connected to the outside of the seal strip 202a.

[0040] In use, the sealing strip 202a is wrapped around the joint between the two coal conveying pipes 101, and then the connecting plates 202b at both ends of the sealing strip 202a are fixed together using bolts to fasten the sealing strip 202a. Under the wrapping action of the sealing strip 202a, the sealing performance of the coal conveying pipe 101 is effectively improved, the spillage of coal powder is prevented, and the purpose of making full use of fuel is achieved.

[0041] As a result, the wrap member 202 achieves the purpose of sealing the joints of the coal transport pipe 101, thereby improving the sealing performance of the entire coal transport pipe 101, preventing coal powder from spilling out, and achieving the effect of fully utilizing the fuel.
