The front and rear sides of the outer shell 1 are rotatably connected to the wheels 2, and the upper right side is connected to the handle 3 by welding, and the surface of the handle 3 is provided with a cushion, making it more comfortable for the user to hold. A plurality of drill bits 4 distributed longitudinally are slidably connected to the left side of the lower part of the shell 1, and the top of the drill bit 4 is connected to The connecting block 401 is provided, and the distance between the bottom surface of the connecting block 401 and the inner bottom surface of the shell 1 is 1-2 cm to ensure that the drill bit 4 drills a hole with a depth of 1-2 cm. The middle position inside the shell 1 is rotatably connected with a rotating shaft 407. The interior of the rotating shaft 407 is connected to a plurality of sleeves 403 by welding. The interior of the sleeve 403 is slidably connected to telescopic blocks 402 distributed on the left and right. The plurality of left telescopic blocks 402 are rotatably connected to the plurality of connecting blocks 401 one by one. The outer top of the shell 1 is connected to a silo 8 by welding. The interior of the silo 8 is connected to a plurality of discharge ports 801 distributed in a straight line by welding. The inside of the feeding port 801 is connected to the blocking cylinder 802 by welding, and is slidably connected to the feeding cylinder 405. The blocking cylinder 802 is sleeved on the upper end of the feeding cylinder 405, so that the upper end of the feeding cylinder 405 is sealed. The feeding port 801 is funnel-shaped, which can guide the rice seeds so that the rice seeds can better enter the inside of the feeding cylinder 405. Each feeding cylinder 405 is horizontally aligned with each drill bit 4 to ensure that the rice seeds are accurately lowered into the hole. The distance between the top surface of the feeding cylinder 405 and the top surface of the blocking cylinder 802 is also 1-2 cm to ensure that when the drill bit 4 moves down to the appropriate position, the feeding cylinder 405 also moves up to close the hole. The outer portion of the lower end of the lower barrel 405 is connected to the connecting ring 406 by welding, and the plurality of right telescopic blocks 402 are rotatably connected to the plurality of connecting rings 406 one by one. The front end of the rotating shaft 407 is connected to the first gear 5 by welding, and the front side of the inner part of the outer shell 1 is connected to the support block 7 by welding. The lower side of the support block 7 is connected to the motor 6 by bolts, and the output shaft of the motor 6 is connected to the second gear 601 by welding, and the second gear 601 is meshed with the first gear 5.

[0021] See Figure 4As shown, it also includes a water tank 9, a water pump 901, a water outlet pipe 902, a suction pipe 903 and a water inlet 904. The water tank 9 is connected to the right side of the lower part of the shell 1 by bolts, and the water pump 901 is connected to the top of the water tank 9 by bolts. A plurality of water outlet pipes 902 distributed in a straight line are connected to the right side of the water pump 901 by welding, and each water outlet pipe 902 is horizontally aligned with each drill bit 4 to ensure that clean water flows accurately into the hole. The bottom of the water pump 901 is connected to the suction pipe 903 by welding, and the outer bottom surface of the suction pipe 903 is close to the inner bottom surface of the water tank 9 to ensure that most of the clean water is pumped away. The water inlet 904 is connected to the left front side of the top of the water tank 9 by welding.

[0022] First, the user pours the germinated rice seeds into the hopper 8, and pours clean water into the water tank 9 from the water inlet 904. Then, the user holds the handle 3 and pushes the housing 1 to the field. Then, the motor 6 is started. The output shaft of the motor 6 drives the second gear 601 to rotate clockwise, so that it meshes with the first gear 5 in a positive direction, and then the first gear 5 drives the rotating shaft 407 to rotate counterclockwise. The rotating shaft 407 drives the sleeve 403 to rotate counterclockwise, so that the left telescopic block 402 pushes the connecting block 401 to move downward, and the connecting block 401 drives the drill bit 401 to rotate in a positive direction. The drill bit 401 is moved downward to drill holes in the field. After drilling is completed, the output shaft of the motor 6 is controlled to reverse, driving the second gear 601 to rotate counterclockwise, so that it meshes with the first gear 5 in the opposite direction, and then the first gear 5 drives the rotating shaft 407 to rotate clockwise, and the rotating shaft 407 drives the sleeve 403 to rotate clockwise, so that the left telescopic block 402 pulls the connecting block 401 to move upward, and the connecting block 401 drives the drill bit 4 to move upward and reset. After resetting, the motor 6 is turned off, and then the housing 1 is pushed to align the discharge barrel 405 with the drilled hole, and the motor 6 is restarted. The output shaft of the motor 6 is controlled to rotate forward, so that the right telescopic block 402 pushes the connecting ring 406 to move downward, and the connecting ring 406 drives the discharge barrel 405 to move downward, so that its upper end is out of contact with the blocking barrel 802, so that the rice seeds in the discharge port 801 enter the discharge barrel 405, and then the discharge barrel 405 is lowered into the hole for sowing. After sowing is completed, the output shaft of the motor 6 is controlled to rotate forward, so that the right telescopic block 402 pulls the connecting ring 406 to move upward, and the connecting ring 406 drives the discharge barrel 405 to move upward. The motor 6 is automatically reset so that its upper end contacts the blocking barrel 802 again and is blocked, preventing the rice seeds in the discharge port 801 from continuing to enter the discharge barrel 405. Finally, the motor 6 is turned off again, the shell 1 is pushed to align the water outlet with the hole, and the water pump 901 is started. The water pump 901 runs to draw the clean water in the water tank 9 into the suction pipe 903, and then transports it to the outlet pipe 902 to flow out into the hole to irrigate the rice seeds and the soil around them. After the irrigation is completed, the water pump 901 is turned off, and the above steps are repeated to continue the sowing operation. After the sowing is completed, the soil can be covered.
