[0025] 3. The multifunctional wheat seeder described in the present invention has a furrowing adjustment component, a synchronous sowing component and an irrigation component. When the furrowing adjustment component adjusts the furrowing spacing between the rotary tillers, the upper sowing frame can be mobilized to slide synchronously through the connected first telescopic rod to ensure that the furrowing position corresponds to the position of falling and sowing seeds. When furrowing, the soil pile is accumulated on one side of the vertical partition. As the device moves, the soil pile plate contacts the accumulated soil and slides upward, causing the blocking plate to slide to one side, thereby opening the sowing hole and allowing the wheat seeds inside to flow. Then the seed sowing operation is performed. While furrowing, the irrigation component sprays water on the flying soil, and then covers the surface of the seeds with the soil containing water again. After the wet soil covers the seeds, a loose and breathable layer is formed. Compared with the traditional method of irrigating the soil on the surface of the seeds, the irrigation water directly penetrates into the dug soil, wraps the seeds with the covering soil, forms a moist layer, and slowly releases moisture through capillary action to reduce evaporation.

[0046] The outer surface of the connecting frame 405 is connected with a synchronous sowing assembly 5;

[0047] The ditching adjustment assembly 4 also includes a connecting rod 409 which is rotatably connected to the side surfaces of the connecting frames 405 on both sides of the middle part through a damping shaft, and the other end of the connecting rod 409 is rotatably connected to the side surface of the outermost connecting frame 405 through a hinge seat, and both side surfaces of the connecting rod 409 are provided with a clamping column;

[0048] One end of the clamping column is rotatably connected to the second adjustment rod 410, and the side surfaces of the second adjustment rods 410 on both sides are fixedly installed with fixed columns, and the outer surfaces of the fixed columns are slidably connected to the adjustment rails 411, and one side of the adjustment rails 411 on both sides is fixedly installed with a fixing frame, and the side surface of the connecting cross plate is fixedly installed with a second electric push rod 412, and one end of the second electric push rod 412 is fixedly installed with a fixing frame;

[0049] The outer surface of the rotating shaft 401 is provided with a plurality of driving grooves 8, and the inside of the driving grooves 8 is slidably connected with an adapter block, which is fixedly mounted on the inner wall of the sliding cylinder 402;

[0051] In this embodiment: before sowing, it is necessary to adjust the furrowing spacing according to different wheat plant types and growth habits. The staff first starts the first electric push rod 408 to drive the first sliding plate 407 to move. The movement of the first sliding plate 407 causes the first adjusting rods 406 on both sides to move. The first adjusting rod 406 drives the connecting frame 405 at one end to move synchronously. The connecting frame 405 on one side drives the connecting frame 405 on the adjacent side to move synchronously through the connecting rod 409.

The appropriate furrowing spacing ensures the growth space of different wheat, ensures that each wheat plant obtains balanced light, ventilation and nutrients, reduces competition between plants, reduces the risk of lodging, and thus increases the wheat yield per unit area;

[0052] During the furrowing process, the drive motor is started to drive the drive rod to rotate, and the drive rod drives the driven shaft to rotate through the pulley assembly, and the driven shaft drives the rotating shaft 401 to rotate. The rotating shaft 401 drives the internal adapter block and the sliding cylinder 402 to rotate through the opened drive slot 8, and the sliding cylinder 402 drives the rotary tiller 403 to rotate, thereby performing the furrowing operation. No matter what spacing the sliding cylinder 402 is adjusted to, it can drive the sliding cylinder 402 to rotate, thereby ensuring the stability of the furrowing device.

In early spring when the temperature is low, mining shallow furrows is conducive to seeds absorbing surface heat and accelerating germination. In the dry season, mining deep furrows is conducive to seeds locking moisture and improving seedling survival rate.

[0056] Embodiment three:

[0057] like Figures 6 to 8 As shown, the synchronous sowing assembly 5 includes a connecting block fixedly connected to the outer surface of the connecting frame 405, the side surface of the connecting block is rotatably connected to the first telescopic plate 501 through a hinge seat, the other side of the first telescopic plate 501 is rotatably connected to the sowing frame 502, and sliding blocks are provided on both sides of the sowing frame 502, and the sliding blocks are slidably connected to the inner top wall of the sowing frame 1;
