The sprinkler pipe 7 can spray clean water on the surface of the soil by setting a water pump 5, a delivery pipe 6 and a sprinkler pipe 7, so as to avoid dust during the sowing process. Support plates 8 are welded at the four corners of the bottom of the base plate 1. The bottom of the support plate 8 is movably connected to a roller 9 through a bearing. The bottom of the base plate 1 is connected to an electric push rod 10 by bolts. The electric push rod 10 is an electric drive device that converts the rotational motion of a motor into a linear reciprocating motion of a push rod. It can be used as an execution machine in various simple or complex process flows to achieve remote control, centralized control or automatic control. The bottom of the electric push rod 10 is fixedly connected to a cross plate 11, and a slotted plate 12 is welded to the bottom of the cross plate 11. By setting the electric push rod 10, the cross plate 11 and the slotted plate 12, it is convenient to open a groove on the soil surface. The right side of the front side of the water tank 4 is connected to a controller 13 by bolts.

[0018] The conveying mechanism 3 includes a conveying cylinder 14, the top of which is connected to the barrel 2, and the bottom of which penetrates to the bottom of the bottom plate 1. The bottom of the conveying cylinder 14 is connected to a servo motor 15 by bolts. The servo motor 15 can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor 15 is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into the motor shaft. The angular displacement or angular velocity output on the conveyor is divided into two categories: DC and AC servo motors. Their main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque. The rotating shaft of the servo motor 15 passes through the inner cavity of the conveying cylinder 14 and is fixedly connected with a conveying blade 16. By arranging the conveying cylinder 14, the servo motor 15 and the conveying blade 16, the corn seeds can be discharged quantitatively to avoid excessive or insufficient discharge. The bottom of the right side of the conveying cylinder 14 is connected to a discharge pipe 17, and the output end of the controller 13 is electrically connected to the servo motor 15 in one direction.

[0019] The number of the barrels 2 is three, and the barrels 2 are arranged at equal distances.

[0020] The left side of the top of the water tank 4 is connected with a water supply pipe 18, and the front and rear sides of the left side of the bottom plate 1 are welded with mounting frames 19. By providing the mounting frames 19, it is convenient for users to install and fix the bottom plate 1 to the agricultural machine.

[0021] A partition 20 is welded to the inner cavity of the water tank 4, and a battery pack 21 is connected to the right side of the bottom of the inner cavity of the water tank 4 by bolts. The output end of the battery pack 21 is unidirectionally electrically connected to the controller 13, and the output end of the controller 13 is unidirectionally electrically connected to the electric push rod 10 and the water pump 5 respectively.

[0022] When in use, the base plate 1 is connected and fixed to the agricultural machine through the mounting frame 19, and then an appropriate amount of seeds are placed in the inner cavity of the barrel 2. The water pump 5 and the servo motor 15 are controlled by the controller 13 to operate. The agricultural machine drives the base plate 1, the support plate 8 and the roller 9 to move through the mounting frame 19, and the slotting plate 12 slots the surface of the soil. The rotating shaft of the servo motor 15 rotates one circle every three seconds, and the rotating shaft of the servo motor 15 drives the conveying blades 16 to rotate. The conveying blades 16 convey the seeds, and the seeds fall to the surface of the soil through the discharge pipe 17. Since the conveying blades 16 only rotate one circle each time, the number of corn seeds discharged each time is basically the same. When the sowing amount needs to be adjusted, it is only necessary to control the speed and running time of the servo motor 15. During the sowing process, the water pump 5 draws clean water from the inner cavity of the water tank 4, and the water pump 5 conveys the clean water to the conveying pipe 6 and the spray pipe 7. The spray pipe 7 atomizes the clean water and sprays it on the surface of the soil, thereby spraying and reducing dust.

[0023] To sum up: the agricultural corn planting quantitative sowing device, through the cooperation of the base plate 1, the barrel 2, the conveying mechanism 3, the water tank 4, the water pump 5, the conveying pipe 6, the spray pipe 7, the support plate 8, the roller 9, the electric push rod 10, the cross plate 11, the slotted plate 12 and the controller 13, solves the problem that the existing agricultural corn planting and sowing devices usually do not have the quantitative sowing function during use, resulting in excessive discharge of seeds during sowing, thereby affecting the sowing effect; and due to the single structure, the surface of the soil cannot be sprayed to reduce dust, resulting in dust easily generated during sowing, reducing the applicability of the agricultural corn planting and sowing device.
