Harvesting, sowing and grass covering all-in-one machine
By installing a seeder, an ultra-long straw slitter and a uniform straw sprinkler at the tail of the harvester, the problem that existing harvesters cannot sow and cover straw at the same time is solved, and simultaneously sowing and covering grass is achieved by harvesting, reducing agricultural costs and carbon emissions.

AI Technical Summary
Existing harvesters can only complete grain harvesting and cannot sow and cover straw at the same time, resulting in difficulties in farming the next maturity and increasing agricultural costs and carbon emissions.
Install a seeder, an ultra-long straw slitter and a full-width evenly spread straw board at the tail of the harvester to achieve the function of simultaneously sowing and covering straw.
The simultaneous sowing and grass cultivation of harvesting have been achieved, which has reduced the need for sowing of cultivated land, reduced agricultural costs and carbon emissions, and reduced the use of fertilizers.

Abstract
Claims
1. A device for harvesting, sowing and covering grass, characterized by: A seeder is installed on the outer side of the upper part of the rear of the harvester. The seeder has a rectangular bracket shape. Bearings are fixed at both ends of the bracket base. A large shaft is installed on the bearings. Scraping blades are fixed on the large shaft. One end of the large shaft is connected to a motor, and the motor is fixed on the support plate. A pipe connection groove is fixed on the base on one side below the large shaft. The end of the seed delivery pipe is inserted into the hole on the pipe connection groove, and the position of the hole corresponds to that of the scraping blade. A seed bin is installed above the large shaft to the upper part of the bracket. A seed outlet is opened at the bottom of the seed bin for the seeds to flow above the large shaft. A U-shaped long brush is installed at the lower edge of the seed bin, and the hair end of the brush presses on the large shaft. When the large shaft rotates, the scraping blade scrapes the seeds and overcomes the block of the brush end to scrape out the seeds. The scraped seeds fall into the corresponding end of the seed delivery pipe below. The seed delivery pipe passes through both ends of the ultra-long straw flicker below and then reaches both sides of the full-width uniform straw spreading board at the bottom. Then it is fixed to the vertical fixing board of the full-width uniform straw spreading board according to a certain slope distribution. Then it passes through the hole on the fixing board and then runs to the vicinity of the lower front corner of the straw spreading piece that is perpendicular to the vertical fixing board but slopes downward at a certain slope and then the seeds fall; The ultra-long straw flicker is fixed in the ear hole in the middle of the inner side of the rear of the harvester. A fixed shaft or a fixed pipe is fixed in the front pair of ear holes. A fixing board is passed through the shaft or the pipe. A working shaft is passed through the rear hole of the fixing board. One end of the working shaft passes through the corresponding rear ear hole of the harvester. A working pipe is sleeved on the working shaft, and a拨动杆 is fixed at the other end. Multiple flicking rods are fixed on the working pipe. One end of each flicking rod is fixed with a blocking needle, and the other end is fixed with a return spring. The other end of the working shaft is connected to the main shaft of the motor. When the motor rotates, the拨动杆 hits the blocking needle to drive the flicking rod to rotate. When the flicking rod is blocked by the rear shell of the harvester, the current of the motor is zero. The flicking rod returns under the action of the return spring to complete the task of flicking the ultra-long straw. The width of the full-width uniform straw spreading board is the same as the actual cutting width of the cutter of the harvester cutting table. It should be noted that there is an unclear "拨动杆" in the original text which may need to be further clarified in the source language for a more accurate translation.
