[0036] Working principle: When the device needs to be used, after connecting the connecting arm 1 to the driving device, the hydraulic cylinder 5 is started to drive the upper rotating frame 6 to rotate, so that the compression spring 7 is squeezed, and at the same time, the lower rotating frame 9 is rotated to lower the raking disc 12 to the ground and contact it, and then the driving device is started to make the raking disc 12 contact the ground through friction, so that it rotates outside the connecting rod 11, and the straw is pushed to both sides to clear the sowing area. When the raking disc 12 needs to be maintained or replaced, the threaded rod 18 is rotated inside the movable sleeve 15 by rotating the rotating ring 19, and at the same time, it is driven to rotate outside the bolt 13, so that the movable sleeve 15 is separated from the bolt 13 and the threaded rod 18 in turn, and then the bolt 13 is rotated out of the inside of the connecting shaft 10, and then the connecting rod 11 is connected. Pulling the connecting shaft 10 to separate it completes the disassembly of the raking disc 12, realizing convenient installation and disassembly of the raking disc 12, making it convenient to maintain or replace it. At the same time, through the operation of the device, the straw can be double-tracked to clear the sowing area at the same time, thereby improving work efficiency.

[0037] By starting the hydraulic cylinder 20, it drives the connecting frame 22 downward through the fixed rod 21, and at the same time, the adjustable frames 23 on both sides are driven to move downward and extend, so that the plow hook 25 and the pressing roller 27 are driven downward to contact the ground. When the straw needs to be cleaned, the seeder is installed on the mounting frame 2, and the grass raking disc 12 cleans the straw to both sides. The field is then turned over and sown through the plow hook 25, and the turned over soil is flattened and covered on the seeds through the pressing roller 27 to complete the planting. This realizes a planting operation that can integrate straw cleaning, turning over and sowing, and soil flattening, improves the efficiency and quality of planting, and reduces the tediousness of manual operation.
