The adjusting mechanism 2 includes a pair of fixing frames 201, and the fixing frames 201 are used to support the lifting plate 301 and a pair of rotating cylinders 202. A pair of rotating cylinders 202 are rotatably connected to the fixing frames 201, and the rotating cylinders 202 can control the lifting of the threaded plate 203 during rotation.

[0031] As Figure 2 shown in the figure, a threaded plate 203 is threadedly connected to the rotating cylinder 202. The threaded plate 203 can be lifted on the rotating cylinder 202, thereby driving the adjusting rod 204 to rotate. An adjusting rod 204 is fixed on the threaded plate 203, and the adjusting rod 204 can rotate following the threaded plate 203, thereby driving the rotating ring 209 and the threaded rod 210 to move.

[0032] As Figure 5 shown in the figure, a rotating block 205 is fixed on each of the plurality of rotating cylinders 202. The rotating block 205 is rotatably connected to the fixing frame 201, and the rotating block 205 is used to connect the rotating cylinder 202 and the rotating plate 206. A rotating plate 206 is fixed on each of the plurality of rotating blocks 205. The rotating plate 206 can drive the rotating block 205 to rotate, thereby driving the rotating cylinder 202 to rotate. A plurality of convex blocks are fixed on the rotating plate 206, and the convex blocks can facilitate the rotation of the rotating plate 206.

[0033] As Figures 2 to 3 shown in the figure, a plurality of limiting grooves 207 are formed in each of the plurality of adjusting rods 204, and the limiting blocks 208 are placed inside the limiting grooves 207. A plurality of limiting blocks 208 are fixed on each of the pair of fixing frames 201. The limiting blocks 208 can support on the side walls of the limiting grooves 207, thereby supporting the adjusting rod 204.

[0034] As Figure 2 shown in the figure, a rotating ring 209 is rotatably connected to one end of each of the plurality of adjusting rods 204, and the rotating ring 209 is used to support the threaded rod 210. A threaded rod 210 is fixed on the rotating ring 209, and the threaded rod 210 can be fixed on the belt conveyor, thereby fixing the rotating ring 209 and the adjusting rod 204.

[0035] As Figures 2 to 3As shown in the figure, the fixing mechanism 3 is installed on a pair of fixing frames 201. The fixing mechanism 3 includes a pair of lifting plates 301, and the lifting plates 301 can move on the fixing frames 201. A plurality of fixing grooves 302 are formed in the lifting plates 301, and the side walls of the fixing grooves 302 can support the positioning blocks 303. A plurality of positioning blocks 303 are fixed on each of the plurality of rotating cylinders 202, and the positioning blocks 303 can be supported on the side walls of the fixing grooves 302, so as to support the rotating cylinders 202 and make it difficult for the rotating cylinders 202 to rotate.

[0036] As Figure 4 shown in the figure, a pair of support rods 304 are fixed on each of the pair of fixing frames 201. The support rods 304 are slidably connected to the lifting plates 301, and the support rods 304 can restrict the movement track of the lifting plates 301. A pair of springs 305 are installed between each pair of lifting plates 301 and the fixing frames 201, and the springs 305 can push the lifting plates 301 to move.

[0037] As Figure 4 shown in the figure, a connecting plate 306 is fixed on each of the pair of lifting plates 301. The connecting plate 306 is used to connect the lifting plate 301 and the baffle 307. A baffle 307 is fixed on the connecting plate 306, and pressing the baffle 307 can drive the connecting plate 306 to move.

[0038] As Figures 4 to 5 shown in the figure, a plurality of sliding grooves 308 are formed in each of the pair of lifting plates 301.

The sliding rails 309 are fixedly connected to the coal heap sensor body 1 and the fixing frames 201, and the sliding rails 309 can be supported on the side walls of the sliding grooves 308, so as to restrict the movement track of the lifting plates 301.

[0039] During specific use, rotate the rotating ring 209, install the threaded rod 210 on the belt conveyor, so as to fix the adjusting rod 204, the fixing frame 201 and the coal heap sensor body 1. Push the baffle 307, and the baffle 307 can drive the connecting plate 306 and the lifting plate 301 to move, so that the positioning block 303 no longer supports on the side wall of the fixing groove 302, and the rotating cylinder 202 can rotate on the fixing frame 201. Moreover, the lifting plate 301 can squeeze the spring 305 during the movement process.

[0040] Rotate the rotary plate 206. The rotary plate 206 can drive the rotary block 205 and the rotary cylinder 202 to rotate. Supported by the limit block 208, the limit groove 207 and the threaded plate 203 are not likely to rotate, so that the rotary cylinder 202 can control the movement of the threaded plate 203 and the adjusting rod 204 during rotation. The adjusting rod 204 can extend from the fixed frame 201, thereby changing the positions of the fixed frame 201 and the coal stacking sensor body 1.

[0041] Release the baffle 307 so that the spring 305 can push the lifting plate 301 to move. During the movement of the lifting plate 301, the positioning block 303 can be supported on the side wall of the fixed groove 302, and the side wall of the fixed groove 302 can support the positioning block 303, so that the rotary cylinder 202 is not likely to rotate, and further the threaded plate 203 and the adjusting rod 204 are not likely to move.
