[0026] Place the fruits and vegetables to be cleaned on the sieve plate 203. Then start the motor 215. The motor 215 drives the motor shaft 216 to rotate, thereby driving the eccentric wheel 214 to rotate. The rotation of the eccentric wheel 214 drives the vibration roller 213 to rotate, thereby pushing the push rod 210 to slide. While the push rod 210 slides reciprocally, the connecting rod Ⅰ 206 slides along the lower sliding groove 204, thereby driving the sieve plate 203 to slide reciprocally along the sieve plate sliding groove 202, completing the preliminary cleaning treatment of the fruits and vegetables, preventing the fruits and vegetables from sticking due to a large quantity, and also pushing the fruits and vegetables onto the conveying component through vibration; While the motor shaft 216 rotates, it drives the driving belt pulley Ⅱ 304 and the synchronous belt pulley Ⅰ 305 to rotate. The driving belt pulley Ⅱ 304 drives the driving belt pulley Ⅰ 303 to rotate through the driving belt 306, thereby driving the transmission shaft 302 to rotate. The rotation of the transmission shaft 302 drives the transmission belt 301 to rotate for conveying. The synchronous belt pulley Ⅰ 305 drives the synchronous belt pulley Ⅱ 309 to rotate through the synchronous belt 307, thereby driving the conveying shaft Ⅰ 308 to rotate. The rotation of the conveying shaft Ⅰ 308 drives the conveyor belt pulley Ⅰ 310 to rotate. The conveyor belt pulley Ⅰ 310 drives the conveyor belt pulley Ⅱ 311 to rotate through the conveyor belt 312, thereby driving the cleaning rod to rotate. At the same time, the conveying roller 328 on the cleaning rod also rotates synchronously, thereby realizing the continuous transportation of the fruits and vegetables.

[0028] As Figures 1-8 As shown, a rotating shaft support frame 412 is fixedly installed on the chassis 1. A cleaning rotating shaft 411 is rotatably installed on the rotating shaft support frame 412. A rotating disc 409 is fixedly installed at one end of the cleaning rotating shaft 411. A belt pulley Ⅱ 325 is fixedly installed at the other end of the cleaning rotating shaft 411. A belt 326 is wound around the outside of the belt pulley Ⅱ 325 and the belt pulley Ⅰ 324. A sliding connecting rod 408 is fixedly installed on the rotating disc 409. One end of the sliding connecting rod 408 is fixedly installed on the rotating disc 409, and the other end of the sliding connecting rod 408 is fixedly installed on the fine spray head 407.

[0029] The rotation of the cleaning rod drives the rotation of the transmission pulley I 313. The transmission pulley I 313 drives the rotation of the transmission pulley II 314 through the transmission belt 315, realizing the rotation of the cleaning brush 410. At the same time, the pulley I 324 rotates, and the pulley I 324 drives the rotation of the pulley II 325 through the belt 326, thereby driving the rotation of the cleaning rotating shaft 411. The rotation of the cleaning rotating shaft 411 drives the rotation of the rotating disc 409, thereby realizing the reciprocating sliding of the fine nozzle 407 along the chute 406. Multiple nozzles are arranged on the fine nozzle 407 to deeply clean the fruits and vegetables rotating and cleaning below. When the fruits and vegetables are transported away from 405, the fruits and vegetables are rolled by the dry brush, thereby achieving a drying effect, which is convenient for subsequent collection.

[0030] As Figures 1-8 shown, the screening device includes a screening support frame 501 fixedly installed on the chassis 1. A small rotating shaft 319, a medium rotating shaft 322, and a large rotating shaft 323 are rotatably installed at the upper end of the screening support frame 501. A connecting pulley II 318 is fixedly installed on the small rotating shaft 319. A connecting belt 327 is wound around the connecting pulley II 318 and the connecting pulley I 317.

A plurality of storage boxes 505 are arranged on the screening support frame 501.

[0032] The fruits and vegetables are gradually transported to the screening mechanism through the conveying component. The rotation of the conveying shaft II 316 drives the rotation of the connecting pulley I 317. The connecting pulley I 317 drives the rotation of the connecting pulley II 318 through the connecting belt 327, thereby driving the rotation of the small rotating shaft 319. The small rotating shaft 319 drives the rotation of the screening pulley 320. The screening pulley 320 drives the rotation of the medium rotating shaft 322 and the large rotating shaft 323 through the screening belt 321, realizing the rotation of the large, medium, and small screening cylinders, and thus completing the collection of fruits and vegetables classified by size.

[0033] The working principle of a fruit and vegetable cleaning and conveying device disclosed by the present invention is as follows: Place the fruits and vegetables to be cleaned on the sieve plate 203, and then start the motor 215. The motor 215 drives the motor shaft 216 to rotate, thereby driving the eccentric wheel 214 to rotate. The rotation of the eccentric wheel 214 drives the vibration roller 213 to rotate, thereby pushing the push rod 210 to slide. While the push rod 210 reciprocates, the connecting rod I 206 slides along the lower sliding groove 204, thereby driving the sieve plate 203 to reciprocate along the sieve plate sliding groove 202, completing the preliminary cleaning of the fruits and vegetables, avoiding the adhesion of fruits and vegetables due to a large quantity, and at the same time pushing the fruits and vegetables onto the conveying component through vibration. While the motor shaft 216 rotates, it drives the driving belt pulley II 304 and the synchronous belt pulley I 305 to rotate. The driving belt pulley II 304 drives the driving belt pulley I 303 to rotate through the driving belt 306, thereby driving the transmission shaft 302 to rotate. The rotation of the transmission shaft 302 drives the transmission belt 301 to rotate for conveying. The synchronous belt pulley I 305 drives the synchronous belt pulley II 309 to rotate through the synchronous belt 307, thereby driving the conveying shaft I 308 to rotate. The rotation of the conveying shaft I 308 drives the conveyor belt pulley I 310 to rotate. The conveyor belt pulley I 310 drives the conveyor belt pulley II 311 to rotate through the conveyor belt 312, thereby driving the cleaning rod to rotate. At the same time, the conveying roller 328 on the cleaning rod also rotates synchronously. When the fruits and vegetables are being conveyed, the rotation of the cleaning rod drives the transmission belt pulley I 313 to rotate. The transmission belt pulley I 313 drives the transmission belt pulley II 314 to rotate through the transmission belt 315, realizing the rotation of the cleaning brush 410. At the same time, the pulley I 324 rotates. The pulley I 324 drives the pulley II 325 to rotate through the belt 326, thereby driving the rotation of the cleaning rotating shaft 411. The rotation of the cleaning rotating shaft 411 drives the rotating disc 409 to rotate, thereby realizing the reciprocating sliding of the fine nozzle 407 along the sliding groove 406. Multiple nozzles are provided on the fine nozzle 407 to perform deep cleaning on the fruits and vegetables rotating and being cleaned below. When the fruits and vegetables are conveyed to a position away from 405, the fruits and vegetables are dried by the rolling of the dry brush. Finally, the rotation of the conveying shaft II 316 drives the connecting belt pulley I 317 to rotate. The connecting belt pulley I 317 drives the connecting belt pulley II 318 to rotate through the connecting belt 327, thereby driving the small rotating shaft 319 to rotate. The small rotating shaft 319 drives the screening belt pulley 320 to rotate. The screening belt pulley 320 drives the middle rotating shaft 322 and the large rotating shaft 323 to rotate through the screening belt 321, realizing the rotation of the large, middle, and small sieve drums, and thus completing the collection of fruits and vegetables classified by size.
