[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, provides a coal feeder anti-blocking coal device, comprising a housing unit 100, comprising a discharge housing 101, and a vibrating inner housing 102 slidably disposed inside the discharge housing 101, and the vibrating inner housing 102 can slide up and down along the discharge housing 101;

[0036] The anti-blocking unit 200 includes a driving member 201 arranged inside the discharge outer shell 101 and located at the lower side of the vibrating inner shell 102, a vibration adjustment rod 202 is arranged on the lower side of the vibrating inner shell 102, and an anti-blocking component 203 is also arranged on the inner side of the vibrating inner shell 102, and the vibration adjustment rod 202 and the anti-blocking component 203 are both connected to the upper end of the driving member 201.

[0037] Furthermore, the discharge shell 101 is a cylindrical structure, with a conical discharge port 101a at the lower end and a protective connecting plate 101b at the upper end. The protective connecting plate 101b is a circular plate for connecting with the front-end equipment and limiting the transportation of materials inside the vibrating inner shell 102.

[0038] Furthermore, a support plate 101c is horizontally arranged inside the discharge housing 101 at the middle of the conical discharge port 101a to provide a placement platform for the drive member 201. A protective cover 101d is arranged at the upper end of the center position of the support plate 101c, and the drive member 201 is arranged inside the protective cover 101d to prevent the material from affecting the drive member 201.

[0039] Furthermore, a limiting ring 101e is provided on the inner side wall of the discharge shell 101. Multiple limiting rings 101e are provided along the height direction of the discharge shell 101. Limiting holes 101e-1 are also provided in an annular manner with equal intervals on the limiting ring 101e. The limiting holes 101e-1 are aligned and penetrate through the multiple limiting rings 101e up and down.

[0040] Furthermore, the vibrating inner shell 102 is a vertical cylindrical structure, whose inner diameter is consistent with the average diameter of the inner and outer rings of the protective connecting plate 101b, and its lower end extends to the upper end of the conical discharge port 101a, and its upper end is a certain distance away from the protective connecting plate 101b to provide space for its vibration. The distance may be five centimeters. A limiting block 102a is vertically arranged on the outer side of the vibrating inner shell 102, and multiple thereof are evenly arranged along the circumference of the vibrating inner shell 102, which are consistent with the number and position of the limiting hole 101e-1, and are matched one by one with the limiting hole 101e-1, and the cross-sectional shape of the limiting block 102a is consistent with the shape of the limiting hole 101e-1.

[0041] Furthermore, a vibration adjustment block 102b is annularly arranged at the lower end of the outer side of the vibration inner shell 102, and a vibration groove 102b-1 is etched on the outer side of the vibration adjustment block 102b, which is wavy in shape and forms a closed-loop groove along the outer side of the vibration adjustment block 102b, and the vibration adjustment rod 202 cooperates with it.

[0042] Furthermore, the vibration adjustment rod 202 is an L-shaped rod, and an adjustment block 202a extends from the side of its vertical section, and its extending length is consistent with the depth of the vibration groove 102b-1. The adjustment block 202a cooperates with the vibration groove 102b-1, and multiple vibration adjustment rods 202 are evenly arranged along the circumferential direction of the driving member 201. The number of periods of the wave curve of the vibration groove 102b-1 is an integer multiple of the number of vibration adjustment rods 202. When the adjustment block 202a is located at the lowest point of the curve of the vibration groove 102b-1, the vibration inner shell 102 is located at the highest position, and when the adjustment block 202a is located at the highest point of the curve of the vibration groove 102b-1, the vibration inner shell 102 is located at the bottom position.

[0043] During use, when conveying materials, the driving member 201 is started, and driven by the driving member 201, the vibration adjustment rod 202 rotates in a circle, thereby driving the adjustment block 202a to rotate in a circle. Thanks to the limitation of the circumferential rotation of the vibration inner shell 102 by the limiting hole 101e-1, the vibration inner shell 102 vibrates up and down at a high frequency between the above-mentioned highest position and the lowest position driven by the reciprocating motion of the adjustment block 202a between the highest point and the lowest point along the curve of the vibration groove 102b-1.

[0044] In summary, the vibration adjustment rod 202 cooperates with the vibration inner shell 102 to generate high-frequency vibration, which can avoid material adhesion while ensuring the stability of the discharge shell 101 and reducing the impact on external equipment.

[0045] Example 2

[0046] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment and provides a device for preventing coal blocking of a coal feeder, which is different from the first embodiment in that:

[0047] The anti-blocking component 203 includes a rotating shaft 203a connected to the driving member 201, which is located at the central axis of the vibrating inner shell 102 and extends to the upper end of the vibrating inner shell 102. An oblique stirring rod 203b and a horizontal stirring rod 203c are arranged on the side of the rotating shaft 203a. There are multiple groups of the two evenly arranged circumferentially and vertically along the rotating shaft 203a, which can fully beat and prevent the material from being bonded. A scraper 203d is rotatably connected to the end of each group of oblique stirring rods 203b and horizontal stirring rods 203c.

[0048] Furthermore, the extended end of the oblique stirring rod 203b is inclined upward, which is used to beat and separate the materials while effectively destroying the arch feet of the materials to avoid the occurrence of arching of the materials. The end of the oblique stirring rod 203b is provided with a connecting shaft 203b-1 and a limit baffle 203b-2, and the scraper 203d cooperates with the two.

[0049] Furthermore, the scraper 203d is an arc-shaped structure, the front end of which contacts the inner wall of the vibrating inner shell 102, and the rear end is provided with a connecting hole 203d-1, which is rotatably connected to the connecting shaft 203b-1. Looking from top to bottom, when the rotating shaft 203a rotates clockwise, the scraper 203d will rotate away from the inner wall of the vibrating inner shell 102 under the action of inertia, so as to prevent the formation of large pieces of material due to the scraper 203d scratching and accumulating. When the rotating shaft 203a rotates counterclockwise, under the action of the limit baffle 203b-2, the scraper 203d stops rotating after contacting the inner wall of the vibrating inner shell 102, so that the inner wall of the vibrating inner shell 102 can be cleaned. This process is carried out when the device stops working and is in the cleaning stage.

[0050] When in use, the driving member 201 is started, and driven by the driving member 201, the oblique stirring rod 203b and the horizontal stirring rod 203c are continuously rotated to beat the materials, so as to separate the sticky materials and avoid the generation of large pieces of materials; when stopping work, the driving member 201 is rotated in the opposite direction, and the inner wall of the vibrating inner shell 102 is cleaned by the scraper 203d to prevent the materials from drying and sticking into blocks after stopping work, which is difficult to clean.

[0051] In summary, the anti-blocking component 203 can beat and separate the material during rotation to prevent large particles from sticking together, and the oblique stirring rod 203b can effectively prevent the material from arching. Together with the scraper 203d, the inner wall of the vibrating inner shell 102 can be cleaned after use to prevent the material from sticking together and accumulating during long-term use to affect the conveying efficiency.

[0052] Example 3

[0053] Reference Figure 7-Figure 8 , which is the third embodiment of the present invention, is based on the above embodiment and is not used in the second embodiment, wherein the anti-blocking component 203 includes a rotating shaft 203a connected to the driving member 201, which is located at the central axis position of the vibrating inner shell 102 and extends to the upper end of the vibrating inner shell 102, and an adjusting unit 300 is arranged on the rotating shaft 203a. A horizontal stirring rod 203c is arranged on the side of the rotating shaft 203a, and multiple groups of the stirring rods 203c are evenly arranged circumferentially and vertically along the rotating shaft 203a, and the end thereof is horizontally rotatably connected with a scraper 203d.

[0054] Furthermore, the adjustment unit 300 includes an adjustment drive 301 fixed to the lower end of the side of the rotating shaft 203a, and an adjustment rod 302 arranged inside the rotating shaft 203a. A telescopic rod connecting block 302a is arranged on the side of the adjustment rod 302, and multiple groups of them are evenly arranged circumferentially and vertically along the adjustment rod 302, and the number is consistent with the horizontal stirring rod 203c. The side wall of the rotating shaft 203a is vertically provided with an adjustment groove 203a-1 at the position of the telescopic rod connecting block 302a, and the telescopic rod connecting block 302a is slidably matched with it. The lower end of the side of the adjustment rod 302 is also extended with an adjustment block 302b, which cooperates with the adjustment drive 301.

[0055] Furthermore, the adjustment unit 300 also includes an adjusting diagonal rod 303 cooperating with the scraper 203d, and a telescopic rod 304 slidably arranged inside the adjusting diagonal rod 303. The sliding and telescopic movement of the telescopic rod 304 along the length direction of the adjusting diagonal rod 303 can adapt to different length requirements between the upper and lower connection positions. The upper end of the adjusting diagonal rod 303 is a first connecting shaft 303a, which is vertically rotatably connected to the upper end of the scraper 203d. The lower end of the telescopic rod 304 is a second connecting shaft 304a, which is vertically rotatably connected to the telescopic rod connecting block 302a.

[0056] During use, when it is necessary to adjust the angle of the adjusting inclined rod 303 according to the different material arching angles generated under different material particle sizes, humidity and other conditions to better intervene in the generation of material arching, the adjusting drive 301 is started, thereby driving the telescopic rod connecting block 302a on the adjusting rod 302 to slide up and down along the adjusting groove 203a-1, thereby adjusting the lower end position of the telescopic rod 304, and then adjusting the angle of the adjusting inclined rod 303. During this process, the telescopic rod 304 slides and retracts along the inside of the adjusting inclined rod 303 according to its inclination angle, so that its length can adapt to different inclination angles.
