Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a device for deep loosening, obstacle breaking, and directional soil improvement in soda saline-alkali soil. Background Technology

[0002] There are two main reasons why soda-alkali soil negatively impacts crop growth: First, its high alkalinity directly affects soil microbial activity and nutrient absorption, leading to a longer growth cycle and reduced yield. Second, the alkaline substances in soda-alkali soil cause loose soil structure, hindering root development and nutrient absorption. Nutrients used in saline-alkali land improvement can effectively neutralize soil alkalinity, adjust soil pH to a suitable range, and simultaneously improve soil microbial activity and structure. Currently available saline-alkali land improvement equipment, during rotary tillage, brings the lower layers of saline-alkali soil to the surface, limiting the effectiveness of soil conditioner application even after treatment. Summary of the Invention

[0016] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 4 As shown in the figure, this embodiment discloses a deep loosening and obstacle-breaking directional soil improvement device for soda saline-alkali soil, including a frame 1. A three-point suspension structure 2 is provided at the front of the frame 1. The three-point suspension structure 2 is connected to a traction machine, which is usually an agricultural tractor.

[0018] The frame 1 is equipped with a transmission box 3 and an additive container 4. The front of the transmission box 3 is equipped with a power input end 5, and the bottom of the transmission box 3 is equipped with a row of spaced power output ends 6. Vertically arranged crushing blades 7 are fixed on the power output ends 6. The length of the crushing blades 7 is usually 35cm. The transmission box 3 is equipped with a transmission assembly 8, and the power input end 5 transmits power to each power output end 6 through the transmission assembly 8.

[0019] Multiple feeders 9 are installed at the bottom of the improver holding tank 4. The feeders 9 are connected to the improver application device 11 through the feed pipe 10. The improver application device 11 is installed on the height adjustment device 12. Each power output end 6 on the transmission box 3 is provided with an application hole 13. The application hole 13 passes through the power output end 6, and the lower end of the improver application device 11 passes through the application hole 13.

[0020] During operation, the power input end 5 is connected to the rear output shaft of the traction machinery via a universal joint coupling. Power input end 5 transmits power to each power output end 6 through the transmission assembly 8. Each power output end 6 drives the crushing blades 7 to rotate circumferentially, thereby breaking up the soil. The soil amendment is stored in the amendment holding tank 4 and discharged through the discharge device 9 into the amendment application device 11, thus applying the amendment to the soil. While the crushing blades 7 rotate circumferentially around the amendment application device 11 to break up the soil, they also evenly mix the applied amendment into the soil.

[0021] This invention breaks up saline-alkali soil without disturbing its stratification, effectively preventing deep saline-alkali soil from turning over to the surface and causing problems such as poor surface soil structure and physicochemical properties. Simultaneously, it is equipped with a soil conditioner positioning and dispensing device, enabling precise and quantitative application of the conditioner. The depth of the conditioner application device 11 can be adjusted using the height adjustment device 12. In this invention, the feeder 9 has the same structure as the existing grooved wheel fertilizer feeder. The grooved wheel fertilizer feeder achieves fertilizer discharge through the rotation of an internal grooved wheel. Its working principle is that the transmission device drives the fertilizer discharge shaft to rotate, the grooved wheel rotates inside the fertilizer discharge box, and the amendment fills the groove. The groove rotates with the grooved wheel to the fertilizer discharge port position. Due to gravity or centrifugal force, the amendment detaches from the groove and is discharged through the discharge pipe 10 to the amendment application device 11. The grooved wheel fertilizer feeder is a commonly used device in agricultural planting machinery, and its specific structure will not be described in detail here. In this embodiment, an electric drive or pneumatic drive device is installed on the frame 1, which provides power for the operation of the feeder 9.

[0022] like Figure 3 As shown, the transmission box 3 includes a box body 301, a drive shaft 302 is provided in the middle of the box body 301, a drive spur gear 303 and an output bevel gear 304 are provided on the drive shaft 302; the output bevel gear 304 is poweredly connected to the power input end 5.

[0023] Multiple driven spur gears 305 are arranged on both sides of the driving spur gear 303. In this embodiment, three driven spur gears 305 are arranged on one side of the driving spur gear 303. The driving spur gear 303 meshes with the adjacent driven spur gear 305, and two adjacent driven spur gears 305 mesh with each other. Each driven spur gear 305 is mounted on a driven shaft 306. The driven shaft 306 is rotatably connected to the transmission box 3 through a bearing assembly. The upper and lower ends of the driven shaft 306 are exposed outside the transmission box 3. The driven shaft 306 is a hollow shaft, and the application hole 13 is provided on the driven shaft 306. The modifier application device 11 passes through the driven shaft 306.

[0024] The power input end 5 includes an input shaft 501, which is rotatably connected to the housing 301 via a bearing assembly. An input bevel gear 502 is mounted on the input shaft 501, and the input bevel gear 502 meshes with the output bevel gear 304.

[0025] The power output end 6 includes a first flange 601 and a second flange 602, which are fixed together by a bolt assembly. The first flange 601 is fixed to the lower end of the driven shaft 306, and the crushing blade 7 is fixed to the second flange 602. In this embodiment, two crushing blades 7 are arranged in a ring on the second flange 602 of the power output end 6, and the crushing blades 7 are shaped with a larger upper part and a smaller lower part.

[0026] Modifier application device 11 passes through first flange 601 and second flange 602, such as Figure 4 As shown, the amendment application device 11 includes a support leg 1101 with a hollow structure. The upper end of the support leg 1101 is connected to the discharge pipe 10, and the lower end of the support leg 1101 is provided with a discharge port 1102 facing the rear of the support leg 1101. A trenching shovel 1103 is provided at the lower end of the support leg 1101.

[0027] The support leg 1101 of the improver application device 11 is mounted on the height adjustment device 12. The height adjustment device 12 includes a support frame 1201. In this embodiment, the lower end of the support frame 1201 is fixed on the housing 301. The upper end of the support frame 1201 is provided with a guide sleeve 1202. The guide sleeve 1202 is fitted and cooperates with the support leg 1101. A locking bolt 1203 is connected to the guide sleeve 1202 and abuts against the support leg 1101.

[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
