A blanking piece is provided on the side of the plurality of fixing rods 15 away from the guide rod 11, and the blanking piece is arranged on the top of the fixing frame 2. The brake piece includes a driving motor 12, a screw rod 13 and a threaded sleeve 14. The top of the fixing frame 2 is fixedly connected to the driving motor 12 by bolts. The driving motor 12 is fixedly connected to the screw rod 13 through the output shaft. The bottom of the screw rod 13 rotates through the fixing frame 2, and the bottom of the screw rod 13 is rotatably connected to the bottom of the inner cavity of the fixing frame 2 through a rotating shaft. The surface of the screw rod 13 is threadedly connected to the threaded sleeve 14, and one side of the threaded sleeve 14 is fixedly connected to one side of the guide plate 4 by bolts.

[0021] By adopting the above technical solution, the sowing trailer 1 can drive its fixed frame 2 and the unloading parts and other related components to move, so as to facilitate unloading and sowing during the movement. By utilizing the driving motor 12 on the top of the fixed frame 2 to adjust the positive and negative output rotation, the screw rod 13 can be driven to rotate, and the two groups of sliding grooves 9 opened on the fixed frame 2 have a limiting effect on its guide plate 4, so that the guide plate 4 can be driven to move up and down through the threaded sleeve 14, so that the guide rod 11 can be guided through the opened guide groove 10, so that the fixed rod 15 fixedly connected to one side of the guide rod 11 slides on the surface of the multiple groups of sliding rods 3, thereby realizing the adjustment of the spacing of the unloading parts provided on one side of the fixed rod 15.

[0022] Reference Figure 1 , Figure 2 and Figure 3 , the feeding parts include a storage box 7, a diverter valve 8, a feeding pipe 5, a sowing head 6 and a telescopic hose 16. The sides of the several fixing rods 15 away from the guide rod 11 are fixedly connected to the feeding pipe 5 by bolts, the bottoms of several groups of feeding pipes 5 are fixedly connected to the sowing head 6 by bolts, the tops of several groups of feeding pipes 5 are fixedly connected to the telescopic hose 16 by clamps, the ends of several groups of telescopic hoses 16 away from the feeding pipe 5 are fixedly connected to the diverter valve 8 by clamps, the top of the diverter valve 8 is fixedly connected to the storage box 7 by bolts, and the bottom of the storage box 7 is fixedly connected to the top of the fixed frame 2 by bolts;

[0023] By adopting the above technical solution, when the spacing adjustment is completed, the diverter valve 8 can be opened to allow the seeds in the storage box 7 to enter the corresponding discharge pipe 5 along the telescopic hose 16, so that the seeding heads 6 fixedly connected to the bottom of multiple groups of discharge pipes 5 can be used to synchronously discharge and sow.

[0024] The implementation principle of the adjustable spacing seeder of the present application embodiment is as follows: the sowing trailer 1 can drive its fixed frame 2 and the material unloading parts and other related components to move, so as to facilitate unloading and sowing during the movement. The drive motor 12 on the top of the fixed frame 2 can be used to adjust the positive and negative output rotation, so as to drive the screw rod 13 to rotate. The two sets of sliding grooves 9 provided on the fixed frame 2 can limit the guide plate 4, so that the guide plate 4 can be driven to move up and down through the threaded sleeve 14, so that the guide rod 11 can be guided through the provided guide groove 10. The fixed rod 15 fixedly connected to one side of the guide rod 11 slides on the surface of the multiple sliding rods 3, so as to adjust the spacing between the discharge pipe 5 and the sowing head 7 and related discharge parts corresponding to the multiple fixed rods 15. When the spacing adjustment is completed, the diverter valve 8 can be opened to allow the seeds in the storage box 7 to enter the corresponding discharge pipe 5 along the telescopic hose 16, so that the sowing head 6 fixedly connected to the bottom of the multiple discharge pipes 5 can be used to discharge and sow synchronously during the overall movement of the sowing trailer 1. The above-mentioned drive motor 12 can be selected from NEMA 17 stepper motor, NEMA 17 stepper motor is a synchronous motor, which controls the movement of the rotor by applying a pulse signal. The rotation angle of the stepper motor is usually controlled by controlling the number of input pulses. Each time a pulse signal is received, the stepper motor will rotate a fixed angle, which is called the step angle. The rotation direction of the stepper motor is determined by the sequence of the input pulse signals and the direction of the current. The forward and reverse rotation of the motor can be achieved by controlling the pulse sequence and the current direction. The above-mentioned diverter valve 8 can use the SS040 hydraulic diverter valve 8. The hydraulic diverter valve 8 realizes the diversion of liquid flow through hydraulic control, and can accurately control the liquid flow of different feeding pipes. It is suitable for the diversion operation of agricultural machinery and equipment such as seed drills. The overall use is simple and easy to operate, and the spacing between multiple groups of feeding and sowing components can be quickly adjusted at the same time, thereby further improving the actual sowing work efficiency when sowing over a large area or with high density.
