[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 In this embodiment of the utility model, a fertilization device for potato planting includes a mounting base 1. A storage tank 2 is detachably connected to the upper surface of the mounting base 1. A cover 305 is movably connected to the upper end of the storage tank 2. A second motor 306 is fixedly connected to the upper surface of the cover 305 near the center. A bladed stirring shaft 308 is fixedly connected to the output end of the second motor 306.

There are two delivery pipes 405, which are rotatably connected to the inner surface of the chamfered plate 403. The delivery pipes 405 are connected to the water tank 401 through the rotary joint 404. A nozzle 406 is fixedly connected to the lower surface of the delivery pipe 405.

[0027] An adjustment mechanism 5 is provided on the lower surface of the L-shaped support plate 101. The adjustment mechanism 5 includes a connecting shaft 501, a gear 502, and a limiting seat 505. The connecting shaft 501 is fixedly connected to the lower surface of the conveying pipe 405 and passes through the C-shaped plate 403 and the L-shaped support plate 101. The gear 502 is fixedly connected to the outer surface of the connecting shaft 501, and the limiting seat 505 is fixedly connected to the lower surface of the L-shaped support plate 101.

[0028] Specifically, during use, the mounting base 1 is installed on the agricultural vehicle with the external threaded assembly. The second motor 306 on the cover 305 is started, and the second motor 306 drives the bladed stirring shaft 308 to rotate, stirring the water and fertilizer to make them evenly mixed. The water pump 102 on the L-shaped support plate 101 is started, and the water pump 102, together with the water inlet pipe 103, draws the water and fertilizer out of the storage tank 2. The water and fertilizer enter the water tank 401, and then enter the delivery pipe 405 through the rotary joint 404. Finally, it is discharged from the nozzle 406 to complete the fertilization operation. The adjustment mechanism 5 can adjust the angle between the two delivery pipes 405 to further adjust the area of ​​water and fertilizer spraying.

[0029] Example 1

[0030] like Figure 1-5 As shown, the inlet of the water pump 102 is fixedly connected to the inlet pipe 103, the inlet pipe 103 is connected to the storage tank 2, the outlet of the water pump 102 is connected to the water tank 401, the inner surface of the storage tank 2 is fixedly connected to the limit strip 201, and the scraper disc 309 is slidably connected to the limit strip 201.

[0031] In this embodiment, water and fertilizer enter the interior of water pump 102 through water inlet pipe 103 and then enter water tank 401. Limiting strip 201 can limit the rise of scraping disc 309. When scraping disc 309 rises, it scrapes the inner wall of storage tank 2 to assist in cleaning the interior of storage tank 2.

[0032] like Figure 1-5As shown, a lifting frame 3 is fixedly connected to the upper surface of the mounting base 1. A trapezoidal lead screw 301 is rotatably connected to the inner surface of the lifting frame 3. A first motor 302 is fixedly connected to the upper surface of the lifting frame 3. The output end of the first motor 302 is fixedly connected to the trapezoidal lead screw 301. A connecting frame 304 is threadedly connected to the outer surface of the trapezoidal lead screw 301. The connecting frame 304 is fixedly connected to the cover 305. A feed hopper 307 is fixedly connected to the upper surface of the cover 305. A corrugated pipe 303 is fixedly connected to the inner surface of the lifting frame 3.

[0033] In this embodiment, the first motor 302 is started, and the output end of the first motor 302 drives the trapezoidal lead screw 301 to rotate. Under the push of the screw, the connecting frame 304 rises or falls, which drives the cover 305 to rise or fall. The cover 305 is connected to the bladed stirring shaft 308 and the scraper disc 309. Therefore, it provides power for the rise or fall of the scraper disc 309, further realizing the stirring of water and fertilizer and the cleaning of the storage tank 2. The corrugated pipe 303 is used to perform dust prevention operation on the trapezoidal lead screw 301.

[0034] Example 2

[0035] Based on Embodiment 1, in order to remedy the problem that the angle of the delivery pipe 405 could not be adjusted in Embodiment 1.

[0036] like Figure 1-5 As shown, the adjustment mechanism 5 also includes a rack 503, a connecting plate 504, an electric push rod 506, and a connecting seat 507. The rack 503 is embedded and slidably connected to the upper surface of the limiting seat 505. The rack 503 and the gear 502 are meshed together. The connecting plate 504 is fixedly connected to one end of the rack 503. The electric push rod 506 is fixedly connected to the lower surface of the limiting seat 505. The output end of the electric push rod 506 is fixedly connected to the connecting plate 504. The connecting seat 507 is nested and connected to the outer surface of the electric push rod 506, and the connecting seat 507 and the connecting plate 504 are fixedly connected.

[0037] In this embodiment, the connecting seat 507, in conjunction with the threaded assembly, mounts the electric push rod 506 onto the limiting seat 505. When the electric push rod 506 is activated, its output end drives the rack 503 to move via the connecting plate 504. The rack 503 drives two gears 502 to rotate. The gears 502 drive the conveying pipe 405 to deflect outward or inward via the connecting shaft 501. At the same time, the rotary joint 404 ensures that the conveying pipe 405 remains connected to the water tank 401 after deflection. The spraying range is maximized when the angle between the two conveying pipes 405 is close to a flat angle, and minimized when the angle between the two conveying pipes 405 is an acute angle, allowing the device to fertilize multiple groups of potatoes.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
