[0002] Returning straw to the field is a method of improving soil fertility and increasing yields, widely valued worldwide. It eliminates air pollution caused by straw burning while simultaneously increasing soil fertility and productivity. Returning straw to the field increases soil organic matter, improves soil structure, loosens the soil, increases porosity, reduces bulk density, and promotes microbial activity and crop root development.

The adjustable-depth straw turning and burying device includes: a shell 1, on which an adjustment mechanism and a leveling mechanism are provided;

[0026] The adjustment mechanism includes two depth limiting components and a drive component;

[0027] The depth limiting assembly includes a strip-shaped fixing plate 2, an internal threaded sleeve 3, a first bevel gear 4, a threaded rod 5, an L-shaped lifting plate 6, and an adjusting wheel 7. The strip-shaped fixing plate 2 is fixedly installed on one side of the outer wall of the outer casing 1. The internal threaded sleeve 3 is rotatably installed on the strip-shaped fixing plate 2. The first bevel gear 4 is fixedly installed on the top end of the internal threaded sleeve 3. The threaded rod 5 is threaded inside the internal threaded sleeve 3. The L-shaped lifting plate 6 is fixedly installed on the bottom end of the threaded rod 5. The adjusting wheel 7 is rotatably installed on the L-shaped lifting plate 6.

[0028] The drive assembly includes two rectangular plates 8, a dual-axis motor 9, two drive shafts 10, and two second bevel gears 11. The two rectangular plates 8 are fixedly mounted on the top of the housing 1. The dual-axis motor 9 is fixedly mounted on the top of the housing 1. The two drive shafts 10 are respectively fixedly mounted on the two output shafts of the dual-axis motor 9. The two drive shafts 10 pass through the two rectangular plates 8 and are rotatably connected to the rectangular plates 8. The two second bevel gears 11 are respectively fixedly mounted on one end of the two drive shafts 10. The second bevel gears 11 mesh with the first bevel gear 4.

[0029] like Figure 1 and Figure 4 As shown, the leveling mechanism includes a scraping plate 30, two L-shaped fixing plates 12, two hollow tubes 13, two push rods 14, two circular plates 15, two telescopic springs 16, and two fixed shafts 17. The scraping plate 30 is hinged to the outer wall of the outer casing 1. The two L-shaped fixing plates 12 are both fixedly installed on the outer wall of the outer casing 1. The two hollow tubes 13 are both hinged to the L-shaped fixing plates 12. The two push rods 14 are slidably installed inside the two hollow tubes 13. One end of each push rod 14 is hinged to the scraping plate 30. The two circular plates 15 are fixedly installed at one end of each push rod 14. A telescopic spring 16 is fixedly installed on the circular plate 15. One end of the telescopic spring 16 is fixedly connected to the inner wall of the hollow tube 13.

[0030] By setting up a leveling mechanism, the soil can be leveled after the soil and straw have been broken up and buried.

[0031] like Figure 2 As shown, a fixed shaft 17 is rotatably mounted inside the outer casing 1, and a plurality of rotary tillage blades 18 are fixedly mounted on the fixed shaft 17. A drive wheel 19 is fixedly mounted on one end of the fixed shaft 17.

[0032] By setting a fixed shaft 17, rotary tillage blades 18 and drive wheels 19, it is possible to crush straw and soil, so that the crushed straw can be buried in the soil.

[0033] like Figure 1 and Figure 2 As shown, connecting rods 20 are hinged to both sides of the outer shell 1, and pressure rollers 21 are rotatably mounted on one end of the two connecting rods 20;

[0034] By setting up the connecting rod 20 and the pressure roller 21, the soil can be compacted after the scraper plate 30 scrapes the soil flat.

[0035] like Figure 1 As shown, a connecting frame 22 is fixedly installed on the top of the outer shell 1, and a connecting seat 23 is fixedly installed on the connecting frame 22;

[0036] By setting up the connecting frame 22 and the connecting seat 23, it is easy to connect the device to the tractor, so that the tractor can carry the device.

[0037] like Figure 1 As shown, positioning blocks 24 are fixedly installed on both sides of the outer shell 1, and the two positioning blocks 24 are respectively located below the two connecting rods 20;

[0038] By setting the positioning block 24, the movement range of the connecting rod 20 can be limited after the traction device is lifted, so as to prevent the pressure roller 21 from moving below the housing 1.

[0039] The working principle of the adjustable-depth straw turning and burying device provided by this utility model is as follows:

[0040] First step: When it is necessary to adjust the straw burial depth during use, start the dual-shaft motor 9. The dual-shaft motor 9 drives the drive shaft 10 to rotate, the drive shaft 10 drives the second bevel gear 11 to rotate, the second bevel gear 11 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the internal threaded sleeve 3 to rotate, the internal threaded sleeve 3 drives the threaded rod 5 to move down, the threaded rod 5 drives the L-shaped lifting plate 6 and the adjusting wheel 7 to move down. After adjusting the position of the adjusting wheel 7, the tractor lowers the device so that the adjusting wheel 7 contacts the ground. Thus, depending on the position of the adjusting wheel 7, the depth to which the rotary tiller 18 inserts into the ground when burying the straw is different, thereby adjusting the straw burial depth.

[0041] The second step: After the soil is turned over and buried, the device moves forward. Under the action of the elastic force of the telescopic spring 16, the bottom of the scraper plate 30 is always in contact with the ground to scrape the soil flat. Then the pressure roller 21 can slightly compact the scraped soil.

[0042] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
