Six sowing boxes 6 are evenly spaced and installed on the rotating rod 5. Through the design of the six sowing boxes 6, the operation is completed. The composite sowing of soybeans and corn in the same row can be achieved in two steps. A transparent plate 7 is embedded in the sowing box 6, and the operator can directly observe the seed situation inside the sowing box 6 through the transparent plate 7. A sowing bucket 9 is provided at the bottom of the sowing box 6, and a rotating disk 8 is rotatably provided on the inner wall of the sowing box 6. A sowing disk 10 is fixedly connected to the rotating disk 8, and more than two discharge troughs 11 are provided on the sowing disk 10 along the circumference. A discharge box 12 is provided on the top of the sowing box 6 for loading seeds, and a discharge hopper 120 is provided at the bottom of the discharge box 12. The discharge hopper 120 is communicated with the sowing box 6 for guiding seeds into the sowing disk 10 in the sowing box 6. The bracket 1 is provided with guides located on the left and right sides of the drive motor 51. Toward box 13, the two guide boxes 13 are each provided with three movable cavities corresponding to the discharge box 12, and a sliding plate 14 is fixedly connected to the rear side of the discharge box 12, and the lower end of the sliding plate 14 slides in the corresponding movable cavity, so that the adjustable sowing spacing operation of the sowing box 6 can be realized, and the bottom end of the sliding plate 14 is provided with a latching tooth 15, and the movable cavity of the guide box 13 is slidably provided with a sliding tooth 16 that meshes with the latching tooth 15 to realize the function of fixing the sliding plate 14, and the bottom of the movable cavity of the guide box 13 is rotatably provided with an adjusting screw 17, and the adjusting screw 17 is threadedly connected to the sliding tooth 16, and the position of the sliding tooth 16 is adjusted by rotating the adjusting screw 17 to realize the engagement or disengagement operation of the sliding tooth 16 and the latching tooth 15.

[0027] First, you need to prepare seeds. According to the planting method of two rows of corn and four rows of soybeans, put seeds into the six feeding boxes 12 in advance, four of which are filled with soybean seeds, and the remaining two feeding boxes 12 are filled with corn seeds. Next, adjust the sowing spacing of soybeans and corn according to the planting specifications. First, turn the adjusting screw 17 to move the sliding teeth 16 downward and disengage the locking teeth 15 at the bottom of the sliding plate 14. At this time, the sliding plate 14 is in a free state. The spacing between the sowing boxes 6 can be adjusted by moving the sliding plate 14 horizontally, thereby controlling the spacing between soybeans and corn. After the adjustment is completed, turn the adjusting screw 17 in the opposite direction to move the sliding teeth 16 to the bottom of the sliding plate 14. The tractor is connected to the connecting block 2 of the device to drive the device to move forward. During the walking process, the drive motor 51 is started, and the drive motor 51 drives the worm 52 to rotate. The transmission of the worm gear 50 and the worm 52 is coordinated to make the rotating rod 5 rotate, and the six rotating disks 8 drive the sowing disk 10 to rotate synchronously. When the discharge trough 11 on the sowing disk 10 is aligned with the lower hopper 120, the seeds in the lower box 12 fall into the discharge trough 11 for collection. As the sowing disk 10 continues to rotate, the seeds are brought to the sowing bucket 9 and finally fall from the sowing bucket 9 to complete the sowing.

[0028] Example 2: Based on Example 1, please refer to Figure 4 and Figure 5 , also includes a support frame 18, a scale plate 19, a connecting plate 20 and an indicator plate 21.

The lower end of the sliding plate 14 is provided with an indicator plate 21 through the connecting plate 20. The indicator plate 21 can slide on the scale plate 19 to display the current sowing spacing. When the sliding plate 14 is moved horizontally to adjust the sowing spacing, the operator can accurately control the spacing of each sowing box 6 by checking the moving position of the indicator plate 21 on the scale plate 19, thereby further improving the accuracy and efficiency of the sowing operation.

[0029] See also Figure 7-Figure 9, also includes a shielding disc 22, a handwheel 23, a baffle 24, a return spring 25 and a block 26. The other side wall inside the sowing box 6 is slidably and rotatably provided with a shielding disc 22, and the shielding disc 22 is also provided with more than two discharge grooves 11 along the circumference. In the initial state, the discharge groove 11 is aligned and communicated with the discharge groove 11 on the sowing plate 10.

The edge of the shielding disc 22 is provided with a number of blocks 26 evenly distributed along the circumferential direction, and the edge of the sowing plate 10 is provided with a number of slots 27 evenly distributed along the circumferential direction, and the slots 27 can be snapped into fit with the blocks 26.

[0030] When the sowing quantity of the sowing plate 10 needs to be adjusted, the hand wheel 23 is held to pull the shielding plate 22 outward, so that the block 26 is disengaged from the slot 27. At this time, the return spring 25 is compressed, and then the hand wheel 23 is turned, and the shielding plate 22 rotates accordingly, so that the shielding plate 22 and half of the discharge trough 11 on the sowing plate 10 are staggered, thereby reducing the sowing amount by half, making it convenient to flexibly adjust according to actual needs, and further improving the flexibility and accuracy of the sowing operation. Then the hand wheel 23 is released, and under the reset elastic force of the return spring 25, the shielding plate 22 is reset, and the block 26 is re-engaged and fixed to the slot 27.
