[0035] Please refer to Figures 1 to 7A preferred embodiment of the utility model provides an anti-blocking spiral ash conveying device, which mainly includes a spiral conveying unit 1, a feeding unit 2 and a switching unit 3.

[0036] The spiral conveying unit 1 is used for spirally conveying ash. The spiral conveying unit 1 is provided with an input port 108 for the ash to enter and an output port 102 for the ash to exit. During implementation, the ash enters from the input port 108 of the spiral conveying unit 1 and is sent out from the output port 102 through the spiral conveying of the spiral conveying unit 1.

[0037] The feeding unit 2 is used to feed the ash into the spiral conveying unit 1. The bottom of the feeding unit 2 is provided with a feeding pipe 202 connected to the input port 108. The ash is fed into the input port 108 through the feeding pipe 202. The feeding unit 2 is provided with a dredging mechanism, which includes a feeding hopper 201, a first motor 204, a connecting rod 205, a rotating rod 207 and a stirring fork 209. The rotating rod 207 is vertically rotatably arranged in the feeding hopper 201 and is located above the feeding pipe 202. The stirring fork 209 is fixedly mounted on the rotating rod 207. The stirring fork 209 is a multi-fork structure with a plurality of forks extending downward, and penetrates into the bottom of the feed pipe 202 and is close to the input port 108. The first motor 204 is fixedly mounted outside the feed hopper 201 and the output shaft of the first motor 204 extends into the feed hopper 201 and is fixedly connected to the connecting rod 205. The connecting rod 205 is fixedly provided with a first bevel gear 206, and the rotating rod 207 is fixedly provided with a second bevel gear 208. The first bevel gear 206 and the second bevel gear 208 are meshed with each other.

[0038] During implementation, the ash enters the spiral conveying unit 1 from the feeding unit 2, specifically from the feeding hopper 201 of the feeding unit 2 through the feeding pipe 202, from the input port 108 of the spiral conveying unit 1 to enter the spiral conveying unit 1 and is spirally conveyed by the spiral conveying unit 1, wherein, when the ash passes through the feeding pipe 202, the first motor 204 starts to drive the connecting rod 205 and the first bevel gear 206 thereon to rotate, and the first bevel gear 206 and the second bevel gear 208 are engaged, thereby driving the rotating rod 207, and the rotation of the rotating rod 207 drives the stirring fork 209 to rotate, so that it can be stirred in the inner cavity of the feeding pipe 202 to break up the hard ash and make the ash entering the input port 108 uniform to facilitate the ash to enter and avoid blocking the input port 108, avoid the problem of ash agglomeration causing blockage at the input port 108 and preventing smooth transportation, and ensure that the ash enters the spiral conveying unit 1 smoothly.

[0039] In a preferred embodiment, a connecting shell 203 is fixedly provided in the feed hopper 201, and a relatively sealed chamber structure is formed inside the connecting shell 203 inside the feed hopper 201, which can effectively prevent ash from entering. The rotating rod 207 is rotatably provided in the connecting shell 203 and extends downward from the connecting shell 203, and a sealing ring is provided at the extending portion. The connecting rod 205, the first bevel gear 206 and the second bevel gear 208 are respectively located in the connecting shell 203. By providing the connecting shell 203 and forming a relatively sealed chamber structure to prevent ash from entering, the influence of ash on the output shaft of the first motor 204 and the meshing of the first bevel gear 206 and the second bevel gear 208 can be effectively reduced, thereby avoiding various rotation or transmission problems.

[0040] Preferably, the switching unit 3 is used to connect with an external ash material input mechanism. The switching unit 3 is arranged on the top of the feeding unit 2 to feed the external ash material into the feeding unit 2. The switching unit 3 has multiple ash delivery paths and can switch the ash delivery paths to achieve ash delivery through different paths. In the case where there are multiple ash producing mechanisms, it is necessary to select and transport between multiple ash materials. By setting the switching unit 3, the ash delivery path can be automatically switched, thereby realizing the function of automatically controlling the path switching, and conveniently connecting the spiral conveying unit 1 with different ash delivery paths, thereby facilitating the connection of different mechanisms and ash delivery.

[0041] The switching unit 3 includes an ash inlet cylinder 301, an ash delivery path pipe 302, a second motor 303, an ash inlet port 305, a disc 306 and a switching port 307. The ash inlet cylinder 301 is fixedly arranged at the upper end of the feed hopper 201. There are multiple ash delivery path pipes 302, and the multiple ash delivery path pipes 302 are respectively connected to the external ash producing mechanism. At this time, one ash delivery path pipe 302 is one ash delivery path. The ash inlet port 305 is opened at the end of the ash delivery path pipe 302 connecting the ash inlet cylinder 301 and connected to the ash inlet cylinder 301. The disc 306 is located in the ash inlet cylinder 301 and the disc 306 abuts against the ash inlet port 305. The switching port 307 is opened on the disc 306. The output shaft of the second motor 303 is connected to the disc 306 to drive the disc 306 to rotate, and when the disc 306 rotates to a certain position, the switching port 307 is opposite to the ash inlet port 305 of one of the ash delivery path pipes 302. During implementation, the disc 306 abuts against the ash inlet 305. At this time, the disc 306 can block the ash inlet 305, and the ash delivery path pipe 302 corresponding to the blocked ash inlet 305 cannot drop material, that is, the ash cannot enter from the ash delivery path pipe 302. When the switch port 307 is directly opposite to the ash inlet 305 of one of the ash delivery path pipes 302, the ash can enter through the ash inlet 305 and the switch port 307, enter the feeding unit 2 through the switch unit 3, and then enter the spiral conveying unit 1. The disc 306 is driven to rotate by the second motor 303, so that the switch port 307 is directly opposite to the ash inlet 305 of one of the ash delivery path pipes 302 to achieve ash feeding of the path. The switch port 307 is adjusted to face different ash inlets 305 to achieve path switching, and the switching function of the ash delivery path is realized. According to different usage scenarios, the ash delivery can be flexibly switched. Of course, it is understandable that when the switch port 307 is not directly facing any ash inlet 305 , the ash inlet is stopped.

[0042] The ash delivery path pipe 302 extends into the ash inlet cylinder 301, the disc 306 fits at the end of the ash inlet port 305, and the second motor 303 is connected to the disc 306 via the adjustment rod 304. The ash inlets 305 of the plurality of ash delivery path pipes 302 are evenly arranged around the circumference of the ash inlet cylinder 301 inside the ash inlet cylinder 301, so that the second motor 303 drives the disc 306 to rotate to control the switch port 307 to face the ash inlet port 305.

[0043] The bottom opening of the ash inlet cylinder 301 is arranged to be open, and the top opening of the feed hopper 201 is arranged to be open, and the bottom opening of the ash inlet cylinder 301 is arranged to face the top opening of the feed hopper 201 to realize the connection between the ash inlet cylinder 301 and the feed hopper 201, and the ash entering the ash inlet cylinder 301 through the ash delivery path pipe 302 directly enters the feed hopper 201.

[0044] The spiral conveying unit 1 also includes a conveying shell 101, a third motor 105, a transmission rod 106 and a spiral blade 107. The input port 108 is arranged at the top of one end of the conveying shell 101, and the output port 102 is arranged at the bottom of the other end of the conveying shell 101. The third motor 105 is fixedly installed on the outside of the conveying shell 101. The transmission rod 106 is rotatably arranged inside the conveying shell 101 and extends from one end of the conveying shell 101 to the other end. The output shaft of the third motor 105 is connected to the transmission rod 106 to drive the transmission rod 106 to rotate, and the spiral blade 107 is wound around the outer periphery of the transmission rod 106. During implementation, the third motor 105 starts to drive the transmission rod 106 to rotate, thereby driving the spiral blade 107 thereon to rotate, and the rotation of the spiral blade 107 gradually pushes the ash material to move toward the output port 102, that is, spiral ash delivery is realized. A fixed frame 104 is fixedly arranged on the outside of one end of the conveying shell 101, and the third motor 105 is fixedly installed on the fixed frame 104. A support frame 103 is provided at the bottom of the transport housing 101 .

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
