Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in figure 1, the sweet potato vine cutting and recycling machine comprises a tractor, a frame 4 fixedly mounted on the tractor, a seedling picking mechanism 1, a feeding mechanism 2, a cutting knife roll 3, a packing auger 5, a conveying device 7 and a seedling collecting box 8 which are sequentially arranged on the frame 4 from front to back, wherein the cutting knife roll 3 is mounted at the front lower part of the frame 4, the feeding mechanism 2 is connected with a swing arm of the frame 4, the seedling picking mechanism is mounted at the foremost end of the frame 4 and adopts a three-dimensional wedge-shaped structure, when the sweet potato vine cutting and recycling machine works, the front end of the seedling picking mechanism 1 moves forwards to pick up seedlings in furrows to move upwards and backwards by clinging to the ground, and the seedlings are conveyed to the feeding mechanism 2, so that the problem that the seedlings in the.

The feeding mechanism adopts swing arm floating type feeding, the feeding roller is in swing arm floating connection with the frame, and can float up and down around the swing arm while doing rotary motion. When the feeding amount is increased, the gap between the feeding roller and the seedling picking shovel is increased, otherwise, the gap between the feeding roller and the seedling picking shovel is reduced. The seedling picking mechanism, the feeding mechanism and the conveying device can all adopt the prior art, and the specific structure is not described again.

The auger of this embodiment level sets up and the pay-off direction of auger is perpendicular with the quick-witted walking direction of recovery, the discharge side of cutting rotor 3 corresponds with the feed inlet of auger, and the output of auger corresponds with conveyor's feed end, and conveyor's discharge end corresponds with seedling collection case. The conveying device is a belt conveyor and conveys the crushed seedling to the seedling collecting box through a conveying belt, and saw-shaped teeth are arranged on a scraper of the conveying belt of the belt conveyor.

The cutting knife roll 3 comprises a knife shaft 13 connected with a power device and a plurality of knife rests fixedly connected to the knife shaft along the circumferential direction, longitudinal cutters 10 extending along the axial direction are fixedly connected to the knife rests, a plurality of transverse cutters 9 are fixedly connected to the longitudinal cutters 10 perpendicularly, the transverse cutters 9 and the longitudinal cutters 10 are welded perpendicularly to form a cross-shaped combined knife, seedling vines are guaranteed to be crushed in time, meanwhile, the cut broken seedling vines can be thrown to a packing auger, and a good cutting effect is achieved.
