The connecting block 32 is connected to the storage One end of the material tank 31 is connected to the center of the end surface. The side wall of the connecting block 32 is provided with a telescopic groove 321. The telescopic groove 321 is provided with a spring 322. One end of the spring 322 is connected to the bottom of the telescopic groove 321, and the other end of the spring 322 is connected with A locking block 323 is connected. The storage tank 31 is clamped to the connecting groove 222 through the connecting block 32, and the locking block 323 is clamped to the locking hole 223 to be connected to the connecting rod 22. The side wall of the storage tank 31 is provided with evenly distributed permeable holes 312.
[0069] Reference image 3 , The outer side of the storage tank 31 is installed with a shielding assembly 4, the shielding assembly 4 includes a shielding box 41 and a filter screen 42, the shielding box 41 is close to the side opening of the connecting rod 22, the side wall of the opening end of the shielding box 41 is provided with a first convex Block 414 and the second bump 415, the peripheral side wall of the connecting plate 412 is provided with a first through hole 416 and a second through hole 417, the first bump 414 is inserted into the first through hole 416, and the second bump 415 Inserted with the second through hole 417, a first fixing hole 418 is formed on the end of the first bump 414 that passes through the first through hole 416, and a first fixing hole 418 is formed on the end of the second bump 415 that passes through the second through hole 417. The two fixing holes 419 are provided with a clamping rod 81 that is clamped to the first fixing hole 418 and the second fixing hole 419 so that the connecting plate 412 is fixed on the shielding box 41.
