[0032] The working principle of the rice planting seeder for uniform sowing provided by the present invention is as follows: When in use, the entire seeder is installed on a vehicle body that can be shaped in the field, and then the required rice seeds are placed in the temporary storage bucket 2. Then, when the vehicle body 1 moves, the motor 309 is started, and the motor 309 drives one of the first transmission rods 305 to rotate. The first transmission rod 305 drives the conveyor belt 304 to rotate through the first pulley 307. The conveyor belt 304 drives the conveyor belt 301 to rotate smoothly at the bottom of the temporary storage bucket 2 through the remaining first pulleys 307 and the second pulley 308 in cooperation with the connecting belt 303. The conveyor belt 301 drives the picking slot 302 to enter the temporary storage bucket 2. At this time, the rice seeds fall into the corresponding picking trough 302. As the conveyor belt 301 continues to rotate, the conveyor belt 301 moves out of the temporary storage bucket 2, thereby scraping off the excess rice planting above the picking trough 302, so as to ensure that the number of seeds in each picking trough 302 is the same. When the picking trough 302 containing rice seeds moves to one end of the conveyor belt 301, the rice seeds in the picking trough 302 fall into the receiving bucket 401, and are finally moved out through the conveying pipe 402 and the mounting hole 502 on the metal rod 501 and sown in the field. At this time, the sowing of rice is completed; When the sowing depth of rice seeds is required to be adjusted, the brake bolt 705 only needs to be rotated to make the brake bolt 705 disengage from the corresponding adjusting rod 703, and then the adjusting rod 703 is pressed down or lifted up, and the adjusting rod 703 drives the metal rod 501 to move until the bottom end of the metal rod 501 is inserted into the ground to a suitable depth, and then the brake bolt 705 is rotated again to make the brake bolt 705 contact with the adjusting rod 703 again, and the rice sowing depth is adjusted at this time. When sowing is not required, the metal rod 501 only needs to be adjusted to the top by the above operation, so that the bottom end of the metal rod 501 is higher than the ground, and the metal rod 501 can be prevented from being damaged when the whole device is moved; When different rice seeds require different planting spacings, first, the adjusting nut 804 is rotated, and then the adjusting screw 803 is pressed down or lifted up. At this time, the adjusting screw 803 drives the horizontal bar 805 to move, the horizontal bar 805 drives the first hinge seat 806 to move, the first hinge seat 806 drives the two hinge rods 807 to move, so that the bottom ends of the two hinge rods 807 located on the same first hinge seat 806 are close to or away from each other, the hinge rod 807 drives the second hinge seat 808 to move, the second hinge seat 808 drives the connecting seat 809 to move, and the connecting seat 80 9 drives the conveying pipe 402 and the second sleeve 702 to move, so that the two adjacent second sleeves 702 are close to or away from each other, the second sleeve 702 drives the adjusting rod 703 to move, and the adjusting rod 703 drives the metal rod 501 to move the groove, so that the distance between the two adjacent sowing rods 501 can be adjusted, so that the rice planting spacing can be adjusted; when the rice planting spacing reaches the required spacing, the adjusting nut 804 is re-tightened to make the adjusting nut 804 contact with the connecting strip 802 again, and the rice planting spacing adjustment work is completed at this time.
