Description

Technical Field

[0001] The present invention relates to the technical field of wheat fertilization, and in particular to a device and method for controlling precise fertilization of wheat endophytes. Background Art

[0002] Wheat is one of the most important food crops in the world. It belongs to the Poaceae family and is the main source of human food. The amount of fertilizer required by wheat in the seedling stage is small, but the amount of fertilizer required by wheat in the growth and maturity stages increases sharply. Therefore, it is very necessary to fertilize on demand according to the actual growth of wheat. At the same time, precision fertilization can effectively enhance the activity of endophytes in wheat and promote the growth of wheat. Most of the existing wheat fertilization devices use manual fertilization. Different farmland soils have different dryness and wetness. Precision fertilization is carried out according to the dryness and wetness of the soil. The labor intensity of fertilization is relatively high. When the soil is relatively dry, more liquid fertilizer is needed. It is also more laborious to dig trenches with a trenching shovel. The operator needs to readjust the amount of fertilizer and the inclination angle of the trenching shovel. The operation is more complicated, the work efficiency is low, and the flexibility is poor.

The amount of fertilizer can be adjusted in real time according to the dryness and wetness of the soil, and fertilization is accurate.

[0024] 2. The trenching mechanism can be set to adapt to the trenching needs of different soils. While adjusting the amount of fertilizer, the first pull rod slides toward the handrail, driving the fourth connecting rod to slide toward the handrail, and the second connecting column also slides away from the trenching shovel, driving the second connecting rod to move away from the trenching shovel, and the trenching shovel rotates accordingly, and the inclination angle of the trenching shovel becomes smaller.

[0051] A method for using a precise fertilizer application control device beneficial to wheat endophytes comprises the following steps:

[0052] When in use, the operator pours different liquid fertilizers into the two fertilizer barrels 31, starts the motor 323, the motor 323 rotates to drive the first rotating shaft 33 to rotate, the stirring rod 331 rotates synchronously with the synchronous wheel 321, and the synchronous belt 322 drives the two fertilizer barrels 31 to stir synchronously to prevent the fertilizers in the two fertilizer barrels 31 from settling to the bottom, ensuring the uniformity of the fertilizers, and rotating the threaded rod 41. After the trenching shovel 413 moves downward to a suitable position, the threaded rod 41 stops rotating;

[0053] The second pull rod 221 is pulled, and the limit block 223 moves toward the inside of the third support plate 22. The first pull rod 353 is pulled according to the dryness and humidity of the farmland soil, and the first pull rod 353 slides toward the handrail 12, driving the wedge block 351 to move toward the handrail 12. The auxiliary wheel 345 slides along the inclined groove in the wedge block 351, and the rack 341 moves away from the wedge block 351, driving the second gear 342 to rotate, and the second shaft 343 rotates accordingly, driving the third gear 344 to rotate synchronously;

[0054] At the same time, the first gear 313 rotates accordingly, driving the unloading plate 314 to rotate, and the first connecting column 318 slides along the first sliding groove 315 accordingly, and the adjusting plates 316 move away from each other, and the bottom of the unloading barrel 311 opens, and the fertilizer can fall from the bottom of the unloading barrel 311 onto the soil. When the operator sees that the indicator block 355 slides out of the third support plate 22, the second pull rod 221 is released, and the limit block 223 is just stuck in the limit groove 354;

[0055] When the soil is relatively drier, the larger the distance between the adjustment plates 316, the greater the amount of material discharged, and the greater the amount of liquid fertilizer applied. While adjusting the amount of fertilizer applied, the first pull rod 353 slides toward the handrail 12, driving the fourth connecting rod 44 to slide toward the handrail 12, and the second connecting column 43 also slides away from the furrow shovel 413, driving the second connecting rod 416 to move away from the furrow shovel 413, and the furrowing shovel 413 rotates accordingly, and the inclination angle of the furrowing shovel 413 becomes smaller. At the same time, the sliding of the second connecting column 43 drives the third connecting rod 434 to rotate, and the furrowing shovel plate 42 also expands outward, which can make the furrowing shovel 413 easier to cut into the soil, with better flexibility and simpler operation, which can improve the fertilization efficiency. After fertilizing the farmland soil, the sprinkler pipe 14 can be used to irrigate wheat after fertilization.

[0056] From the above description, it can be seen that the first connecting column 318 of the above-mentioned embodiment of the present invention slides along the first slide groove 315, can adjust the bottom opening of the discharge barrel 311, and can adjust the amount of fertilizer in real time according to the dryness and humidity of the soil. At the same time, the first pull rod 353 slides toward the handrail 12 to drive the fourth connecting rod 44 to slide toward the handrail 12, the inclination angle of the trenching shovel 413 becomes smaller, and the trenching shovel plate 42 also expands outward, which can make the trenching shovel 413 easier to cut into the soil and has better flexibility.

[0057] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
