[0015] As further optimized content of the present invention, among which: S1: the seeding box assembly sorts the seeds during the equidistant sowing process: the position of the inner wheel with a rod in the wheel axle is adjusted to change the rolling radius of the wheel axle, the rotation of the wheel axle drives the screening wheel to rotate, and the seeds soaked in the filter bucket are placed in the chute, and the screening wheel will rotate and transport the seeds rolling down the inclined surface of the chute to the discharge nozzle in batches; S2: The seed pressing component pushes the crop seeds downward to plant them: the wheel shaft rotates through the belt to drive the belt rotating disk to rotate, the belt rotating disk drives the grooved rotating disk to rotate through the inter-block rotating column, the grooved rotating disk rotates to drive the capped long rod to move downward, the capped long rod moves to drive the plug rod to move, the plug rod moves to drive the plug head to move, and the plug head moves to press the crop seeds downward; S3: The control of the digging depth and size of the planting pit by the digging component: When the plug squeezes the crop seeds downward, the width of the duckbill piece is different due to the different sizes of the crop seeds. The width of the duckbill piece affects the digging size of the planting pit. At the same time, due to the different volumes of the seeds, the time for the plug to work the duckbill piece downward through the seeds is also different. The duckbill piece is subjected to downward pressure, which is transmitted to the sliding rod in the block through the rotating pin and the clamp, so that the sliding rod in the block compresses the reset spring to adjust the planting depth; S4: Transmission and reset of the movable sleeve assembly between devices: When the duckbill piece is stretched open, it squeezes the cardboard to move the cardboard. When the cardboard moves upward, it drives the slotted sleeve to move upward. The movement of the slotted sleeve will drive the transmission rod fixed on one side to move. At the same time, the inter-tube rotating groove and inter-tube sliding groove opened on the outside of the slotted sleeve can avoid the slotted sleeve from being blocked by other components. When the plug moves to the uppermost end, the slotted sleeve falls due to its own gravity, and at the same time drives the duckbill piece to close through the cardboard; S5: The water tank assembly is used to irrigate the crops after planting: unscrew the cap and inject water into the tank slot through the tank nozzle. Since the transmission rod moves relatively according to the moving distance of the slotted sleeve, the movement of the transmission rod drives the water plug to slide in the limit ring frame. When the water plug slides upward, the water inside the tank slot will flow out from the through hole and flow to the ground through the sprinkler hole. The different moving distances of the water plug will result in different numbers of through holes that can be unblocked, thereby affecting the amount of water for irrigation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by setting up the planting components, the depth of the planting pit can be adjusted according to the size of the seeds during the sowing operation of the device without stopping the machine or manual intervention, thereby ensuring that the seeds are sown at the most suitable depth, avoiding the difficulty of germination of seeds or the occurrence of plant lodging due to inappropriate planting pits, ensuring work efficiency and reducing the labor intensity of workers.

[0017] 2. In the present invention, the water tank assembly is provided to make the irrigation operation more convenient and efficient. By controlling the movement of the water plug, the amount of water for irrigation can be accurately controlled, avoiding the waste of water resources and uneven soil moisture caused by traditional flood irrigation, helping to maintain the optimal moisture content of the soil and promote rapid germination and healthy growth of seeds.

[0018] 3. In the present invention, the seeding box assembly is provided so that the seeds are screened and disinfected before sowing, and then the seeds are pushed evenly into the soil through the precise pressure of the seed pressing assembly, thereby increasing the contact area of ​​the seeds and ensuring good contact between the seeds and the soil, which is beneficial for the seeds to absorb water and nutrients and improves the survival rate and growth quality of the crops.

10. A method for using an adjustable equidistant agricultural sowing device according to any one of claims 1 to 9, characterized in that: S1: The seeding box assembly (4) sorts the seeds during the equidistant seeding process: the position of the inner wheel with a rod (3) in the wheel shaft (2) is adjusted to change the rolling radius of the wheel shaft (2). The rotation of the wheel shaft (2) drives the screening wheel (43) to rotate, and the seeds soaked in the filter bucket (42) are placed in the chute (413). The screening wheel (43) will rotate and transport the seeds rolling down the inclined surface of the chute (413) to the discharge nozzle (415) in batches; S2: the seed pressing component (51) pushes the crop seeds downward to plant them: the wheel shaft (2) rotates to drive the belt rotating disk (513) to rotate through the belt, the belt rotating disk (513) drives the grooved rotating disk (514) to rotate through the inter-block rotating column (512), the grooved rotating disk (514) rotates to drive the capped long rod (515) to move downward, the capped long rod (515) moves to drive the plug rod (516), the plug rod (516) moves to drive the plug head (518), and the plug head (518) moves to press the crop seeds downward; S3: The digging assembly (53) controls the digging depth and size of the planting pit: When the plug (518) presses the crop seeds downward, the widths of the duckbill piece (536) are different due to the different sizes of the crop seeds. The width of the duckbill piece (536) affects the digging size of the planting pit. At the same time, due to the different volumes of the seeds, the time for the plug (518) to work the duckbill piece (536) downward through the seeds is also different. The duckbill piece (536) is subjected to downward pressure, which is transmitted to the sliding rod (532) in the block through the rotating pin (535) and the clamp (534), so that the sliding rod (532) in the block compresses the return spring (533) to adjust the planting depth; S4; Transmission and resetting of the movable sleeve assembly (52) between devices: When the duckbill piece (536) is stretched open, the card plate (526) is squeezed to move the card plate (526). When the card plate (526) moves upward, the grooved sleeve (521) is driven to move upward. The movement of the grooved sleeve (521) drives the transmission rod (61) fixedly connected on one side to move. At the same time, the inter-tube rotating groove (522) and the inter-tube sliding groove (523) provided on the outer side of the grooved sleeve (521) can prevent the grooved sleeve (521) from being obstructed by other components. When the plug (518) moves to the uppermost end, the grooved sleeve (521) falls due to its own gravity and drives the duckbill piece (536) to close through the card plate (526).
