[0024] Specifically, as shown in Figure 2 When it is necessary to adjust the position of the charging hopper 302, the fixed block is first taken out of the fixed hole by rotating the threaded rod 204, and then the adjusting block 202 is appropriately moved leftward or rightward, and the movement of the adjusting block 202 will drive the guide block 203 to move along the guide rod 201, so that the movement of the adjusting block 202 is in a horizontal movement state.

[0025] Specifically, as shown in Figure 4As shown, when the adjusting block 202 moves, the movable extrusion block 207 is extruded by the outer surface of the rack 208, and then is temporarily retracted into the inside of the extension sleeve 205 and extrudes the spring body 206, and then when the adjusting block 202 moves to the appropriate position, the movable extrusion block 207 is pushed out of the inside of the extension sleeve 205 under the action of the spring body 206, and cooperates with the rack 208 to preliminarily fix the position of the adjusting block 202, and then rotates the threaded rod 204 to drive the fixed block to insert into the fixed hole, so as to secondarily fix the position of the adjusting block 202, thereby adjusting and fixing the position of the charging hopper 302.

[0026] Specifically, as shown in the figure, Figure 3 The corn seeds are respectively placed in the inside of the five charging hoppers 302, and then the rotation power of the five drive motors 305 is controlled by the motor adjuster 301, so as to adjust the rotation frequency of the rotating rod 303, when the charging groove 304 of the rotating rod 303 rotates to the inside of the charging hopper 302, the corn seeds will enter the inside of the charging groove 304, and then when the rotating rod 303 rotates to the outlet of the charging hopper 302, the corn seeds will be poured out of the inside of the charging hopper 302 under the influence of gravity, and the sowing process is carried out.

Its working principle is to switch control of electric energy by power semiconductor devices to change the size and waveform of output voltage or current, so as to realize accurate adjustment of the rotation speed of the motor. Specifically, the input alternating current is converted into direct current by the rectifier unit, and then is smoothed by the filter circuit, and then is modulated by the power control unit according to the control signal to generate the required output voltage or current. The feedback control system monitors the output parameters in real time and compares them with the set value. If there is a deviation, the working state of the power control unit is adjusted to ensure that the output parameters remain stable. At the same time, the protection circuit is used to prevent overvoltage, overcurrent or short circuit and other abnormal conditions to ensure the safety of the equipment and the load.
