Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fruit picking equipment, and specifically relates to a traction type fruit picking secondary impurity removing device. BACKGROUND

[0002] Fruit harvesting generally adopts mechanical vibration or manual knocking to make the ripe fruits on the tree fall down, and then the fallen fruits are picked up and classified by a fallen fruit picking and cleaning device.

[0003] The applicant submitted a utility model patent application for a cleaning device for fruit picking on December 6, 2024, with the application number 202423024823.6. The technical solution discloses that the production cost is reduced by modularizing the drive mechanism and the rack, and the fallen fruits are lifted to the lifting assembly, and the fallen fruits are blown off the lifting assembly for air separation, which can pick up the fallen fruits and remove the leaves, dust and other impurities, solving the problems of high production cost and limited impurity removal effect of the existing picking and cleaning equipment. However, it is found in use that the device has certain requirements for the forest road. Since air separation can only remove light impurities, heavy impurities such as soil, branches and stones cannot be removed, so the forest road needs to be cleaned before use. Secondly, since the air outlet is inclined upward, dust will be blown into the air during air separation, which is inconvenient to use.

[0004] Chinese patent ZL201710017425.7 discloses a brush type crawler type dry jujube picking machine, which includes a crawler type power walking chassis, a brush type picker is arranged at the front end of the chassis rack of the walking chassis, a spiral scraper conveyor is arranged at the rear end of the brush type picker, a conveyor is arranged at the rear end of the spiral scraper conveyor, an outlet is arranged at the upper part of the conveyor, a strip cleaning slide is arranged at the lower part of the outlet, a cleaning fan is arranged at the bottom of the conveyor and adjacent to the lower part of the strip cleaning slide, a jujube collecting box is arranged at the lower part of the strip cleaning slide. The picking machine has simple structure, low cost and good stability, can realize picking and cleaning of fallen red dates, and can be used for multiple purposes, but the technical solution also uses a cleaning fan to discharge leaves and impurities from the rear discharge port. Since the cleaning fan can only remove light impurities, it cannot remove heavy impurities such as branches and soil, so the cleaning effect is limited, and since the air outlet of the cleaning fan is also inclined upward, a large amount of dust is generated during use.

[0061] Since the impeller 423 in the fan 42 is connected with the sixth transmission cross shaft 27, and the fifth transmission cross shaft 26 is in transmission connection with the fourth transmission cross shaft 25 through the transmission member 28, the impeller 423 continuously discharges the air in the fan 42 from the air outlet 421 during the rotation of the sixth transmission cross shaft 27, the air blows upward from the bottom of the second conveying mechanism 41, blows the sundries with light weight on the second conveying mechanism 41 into the sundry removal cover 43, and is discharged to the side of the rack 1 along the sundry discharge pipe 431 on the sundry removal cover 43, to realize the first cleaning;

[0062] The heavy quality fallen fruit and branches, soil blocks and other sundries are continuously conveyed upward by the second conveying mechanism 41, and after moving to the top of the second conveying mechanism 41, fall downward on the grid 44, since the intervals on the grid 44 are set to be adapted to the maximum width of the fallen fruit, the fallen fruit can fall downward from the intervals on the grid 44 into the transfer box 45 for collection, and after one transfer box 45 is collected full, a new transfer box 45 is replaced on the placing plate 16, and sundries of different shapes and sizes slide downward along the upper surface of the grid 44 and are finally discharged, realizing the second cleaning;

[0063] After the first cleaning of the light quality sundries, the second cleaning of the heavy quality sundries but different from the fallen fruit in shape and volume, the fallen fruit on the ground can not only be picked up, but also be removed of sundries through the two times of cleaning, the picking and cleaning efficiency is high, the use is convenient, the difficulty of manual operation is greatly reduced, and the picking and cleaning device has wide popularization and application value in the technical field of the picking and cleaning device.
