Technical Field

[0001] The present invention relates to the field of cleaning machines for lily crop ground stems, and particularly to a lily ground stem cleaning machine. Background Art

[0002] Lilies belong to herbaceous bulbous plants of the Liliaceae family. Lilies combine food and medicinal uses, have a vast planting area and high demand. The main part harvested is the underground bulb of the lily, while the ground stem part needs to be removed before harvesting the underground bulb part. There is an urgent need for a machine to process the non-harvested stem part in the early stage of lily harvesting operation to meet the bed surface conditions during the operation of the lily digging harvester and improve the subsequent harvesting efficiency.

[0003] Chinese Patent CN104285582A discloses a lily cutting and harvesting machine, which includes a cutting mechanism, a digging device, a chain vibrating screen, a conveyor belt, a cleaning drum and a collection box. The digging device is provided on the frame. The digging device shovels the soil of the lily ridge and shovels up the lily together with the soil blocks. The lily and the soil blocks move along the digging surface of the digging device into the chain vibrating screen. The chain vibrating screen is inclined and connected to the frame. The eccentric connecting rod set on the power wheel drives the chain vibrating screen to reciprocate. The chain vibrating screen vibrates to break the soil blocks and shake off the soil adhered to the soil, and the soil falls along the sieve holes. The lily moves along the chain vibrating screen into the conveyor belt, and the lily enters the cleaning drum through the conveyor belt. The cleaning drum is provided with multiple rows of uniformly distributed round holes, and a guide plate is provided on the inner wall of the cleaning drum. The guide plate is arranged at an angle of 30 degrees with the axis direction of the cleaning drum. The lily tumbles up and down in the cleaning drum, and the soil and small sundries are discharged through the round holes. The lily advances forward along the spiral direction formed by the guide plate and finally enters the collection box. This cutting and harvesting machine includes a cutting mechanism, a digging device, a chain vibrating screen, a conveyor belt, a cleaning drum and a collection box, and realizes cutting, collection, digging, separation, cleaning and automatic collection through the combination of a horizontal cutting knife, a hydraulic motor, a double-acting lifting oil cylinder, a blower, a chain vibrating screen, a conveyor belt, a cleaning drum and a collection box.
