[0003] During the conveying process, sludge tends to adhere to the belt surface of the belt conveyor, which will not only increase the running resistance of the belt and reduce the conveying efficiency, but may also cause the sludge to splash around during the operation of the belt, causing environmental pollution and safety hazards, and affecting its service life. The purpose of the sludge conveying device is difficult to clean automatically and cannot meet the use requirements. Utility Model Content

[0014] The utility model provides an automatic cleaning effect for the conveyor by setting a cleaning mechanism. The hydraulic cylinder can drive the combined shell to move. When the sludge is conveyed and the conveyor needs to be cleaned, the hydraulic cylinder is started to make the brush plate and the bottom of the rubber strip contact with the conveyor surface belt. At this time, the reciprocating screw rod is rotated so that the sliding sleeve can drive the connecting plate to move back and forth on the surface of the reciprocating screw rod, so that the brush plate and the rubber strip can scrape the conveyor surface belt back and forth. Since the rubber strip and the brush have good elasticity and toughness, they can fit closely to the belt surface and penetrate into the belt texture through reciprocating motion, so as to effectively scrape and clean the sludge and other fine particles adhering to the belt, thereby achieving a good cleaning effect and making the sludge It will no longer adhere to the belt surface. Before that, start the air pump and the exhaust fan. The air pump can blow out high-pressure airflow. The high-pressure air can use the strong impact force of the airflow to quickly remove the loose, easy-to-blow-off dust and large particles on the belt surface, reduce the burden of subsequent physical cleaning, and avoid excessive wear of these debris on the rubber strips and brushes. After the belt is cleaned by the brush plate and rubber strip, the exhaust fan can cooperate with the diversion pipe to adsorb the belt surface, and can quickly absorb the dust and small particles raised during the cleaning process to prevent them from re-depositing on the belt or drifting into the surrounding environment. The scraper can scrape the belt surface so that the sludge fragments remaining on the belt surface can be taken out normally, thereby completing the automatic cleaning of the conveyor.

[0024] The conveyor 1 is used to convey sludge, the cleaning mechanism 2 enables the conveyor 1 to achieve an automatic cleaning effect, and the cutting mechanism 3 enables the sludge to be cut.

[0025] The cleaning mechanism 2 includes a mounting shell 201, a combined shell 202 is arranged inside the mounting shell 201, two reciprocating screw rods 203 are rotatably connected to the inner wall of the combined shell 202, a sleeve 204 is threadedly connected to the surface of the reciprocating screw rod 203, a connecting plate 205 is fixed to the bottom of the sleeve 204, a brush plate 206 and a rubber strip 207 are fixed to the bottom of the connecting plate 205, an air pump 208 and an exhaust fan 211 are fixed to the top of the mounting shell 201, one end of the air pump 208 is connected to a connecting pipe 209, and the connecting pipe 209 passes through the combined shell 202. The connecting pipe 209 is fixedly connected to the combined shell 202 at the penetration point, a corrugated pipe is installed on the surface of the connecting pipe 209, a blowing pipe 210 is connected to the bottom of the connecting pipe 209, a collecting box 212 is connected to the surface of the exhaust fan 211, a shunt pipe 213 is connected to the surface of the collecting box 212, the surface of the shunt pipe 213 penetrates the installation shell 201, a scraper 215 is slidably connected to the surface of the conveyor 1, a hydraulic cylinder 218 is fixed on the top of the installation shell 201, one end of the hydraulic cylinder 218 penetrates the installation shell 201 and is fixedly connected to the combined shell 202;

[0026] The hydraulic cylinder 218 can drive the combined shell 202 to move. When the sludge is transported, the conveyor 1 needs to be cleaned. The hydraulic cylinder 218 is started to make the brush plate 206 and the bottom of the rubber strip 207 contact the surface belt of the conveyor 1. At this time, the reciprocating screw 203 is rotated to make the sleeve 204 drive the connecting plate 205 to move back and forth on the surface of the reciprocating screw 203, so that the brush plate 206 and the rubber strip 207 can scrape the surface belt of the conveyor 1 back and forth. Since the rubber strip and the brush have good elasticity and toughness, they can fit closely to the belt surface, and can penetrate into the belt texture through reciprocating motion, effectively scraping and cleaning the sludge and other fine particles adhering to the belt, so as to achieve a better cleaning effect and prevent the sludge from adhering to the belt surface. Prior to this, start the air pump 208 and the exhaust fan 211. The air pump 208 can blow out a high-pressure airflow.

[0035] Furthermore, a guide rod 219 is passed through the surface of the mounting shell 201, and the bottom of the guide rod 219 is fixedly connected to the top of the combined shell 202;
