[0015] 1. This utility model proposes a harvesting device with a screening function. In the screen mechanism, the second screen is fixed by bolts and can slide along the guide rail, making its disassembly and replacement more convenient. When facing the screening needs of different varieties and growth stages of Chinese herbal medicines, the operator only needs to unscrew the fixing bolts and slide along the guide rail to quickly remove the second screen and replace it with a screen of appropriate aperture, which greatly shortens the equipment adjustment time. At the same time, in the auxiliary mechanism, the fan generates wind power, which is transmitted to the blowing box through the conveying pipe. It can clean the soil, weeds and light impurities on the surface of Chinese herbal medicines in a timely manner during the harvesting process. The combination of convenient screen maintenance and wind-assisted cleaning not only ensures the continuous and efficient screening work, but also reduces the clogging and wear of the screen by impurities, effectively improving the ease of use and service life of the device.

[0016] 2. This utility model proposes a harvesting device with a screening function. This harvesting device achieves efficient and accurate screening through the ingenious cooperation of a first screen, a screen mechanism, and a vibrating motor. After the vibrating motor is started, it drives the entire main body of the device to vibrate, causing the Chinese herbal medicines and impurities to move fully within the device, breaking up the agglomeration state, and making it easier to separate materials of different sizes. The first screen first performs preliminary screening of the excavated Chinese herbal medicines, intercepting larger Chinese herbal medicines and branches. Smaller materials pass through the first screen and are then finely screened and graded by the second screen of the screen mechanism. This multi-stage screening mechanism, combined with the vibration effect, effectively avoids material clogging of the screen, greatly improves screening efficiency and accuracy, and ensures that the harvested Chinese herbal medicines are of uniform size and excellent quality.
