[0039] Among them, the outer side of the roller shaft 211 close to the uniform mixing and discharging mechanism 3 is connected with a driving motor, the driving motor is used for driving the conveying roller 21 to rotate so as to drive the conveying belt 22 to move, and the discharging port of the uniform mixing and discharging mechanism 3 is located above the conveying belt 22;

[0040] A cleaning brush 4 and a wiping mechanism 5 are installed below the discharging end of the conveying belt 22, the upper end of the bristles of the cleaning brush 4 is in contact with the lower end of the conveying belt 22, and the end of the wiping mechanism 5 is in contact with the lower end of the conveying belt 22 and one side of the cleaning brush 4;

[0041] The base 1 is also provided with a transmission assembly 7, the transmission assembly 7 drives the cleaning brush 4 and the wiping mechanism 5 to rotate synchronously with the rotation of the roller shaft 211.

[0042] Based on the above structure, during the automatic addition of the preservative and mildew-proof agent, the roller shaft 211 rotates to drive the cleaning brush 4 and the wiping mechanism 5 to rotate synchronously through the transmission assembly 7. The cleaning brush 4 performs primary cleaning on the lower end of the conveying belt 22, and the wiping mechanism 5 performs secondary cleaning on the lower end of the conveying belt 22 and continuously knocks the bristle end of the cleaning brush 4, so that the preservative and mildew-proof agent attached to the cleaning brush 4 falls off. In this way, the preservative and mildew-proof agent powder attached to the surface of the conveying belt 22 can be effectively cleaned and removed, and the fallen preservative and mildew-proof agent powder is concentrated below the lower end of the conveying belt 22, avoiding random scattering of the preservative and mildew-proof agent powder and pollution of the surrounding environment of the device.

The fixed sleeve 52 is fixedly sleeved on the rotating shaft 51. The fixed sleeve 52 is provided with a mounting groove 521.

[0044] The wiping block 53 is slidably embedded in the mounting groove 521. The end of the wiping block 53 extends out of the mounting groove 521 and movably abuts against the bottom surface of the conveying belt 22 and the bristle end of the cleaning brush 4 during rotation. The wiping block 53 is made of a material (such as stainless steel) that is smooth on the surface and not easy to attach preservative and mildew-proof agent powder, so that the preservative and mildew-proof agent powder is prevented from being attached to the conveying belt 22 again through the wiping block 53.

[0045] The mounting groove 521 is provided with a plurality of mounting grooves 521 and is circumferentially distributed along the axis of the rotating shaft 51.

[0057] Through the setting of the guide arc plate 6 and the material collecting box 8, the falling preservative and mildew-proof agent powder can be guided, so that the preservative and mildew-proof agent powder is concentrated to fall into the material collecting box 8, thereby completing the automatic collection work of the preservative and mildew-proof agent powder falling off the conveying belt 22, facilitating subsequent recycling or use, and being more convenient to use.

[0058] Further, the front and rear edges of the conveying belt 22 are formed with protruding flanges 221, the width of the bristles of the cleaning brush 4 and the wiping block 53 is consistent with the spacing between the two flanges 221, and the ends of the bristles of the cleaning brush 4 and the wiping block 53 extend into the space between the two flanges 221 and contact the lower end of the conveying belt 22.

[0059] Through the setting of the flanges 221, the preservative and mildew-proof agent powder falling on the conveying belt 22 can be limited, so that the preservative and mildew-proof agent powder is not scattered and falls due to vibration during movement of the conveying belt 22, thereby being more conducive to stable addition of the preservative and mildew-proof agent.
