[0030] Specifically, the staff only needs to set the time for water and fertilizer discharge on the electronic table 6. When the equipment is started, the electric push rod 9 will drive the sawtooth bar 7 to move; the sawtooth bar 7 slides in the slide groove 21, and its movement trajectory is carefully designed to ensure smooth meshing transmission with the metal gear 19; as the sawtooth bar 7 moves, the metal gear 19 and the worm 10 begin to rotate; this rotation action further drives the rotating rod 8 and the worm 2 16 to rotate synchronously through the meshing transmission of the worm 10 and the worm wheel 18; the meshing transmission of the worm 2 16 and the worm wheel 2 15 finally drives the worm wheel 2 15, the connecting rod 14 and the plugging piece 12 to rotate synchronously; In this series of mechanical actions, the rotation of the plugging piece 12 is the key; when the plugging piece 12 rotates to a certain position, the corresponding through hole on the water leakage plate 13 will be exposed, so that water and fertilizer can be discharged through the water leakage plate 13 for irrigation; this process is fully automated and does not require manual operation, which greatly saves time and manpower; when the preset irrigation time is reached, the electric push rod 9 will automatically retract, driving the sawtooth bar 7 and the plugging piece 12 to retract; the plugging piece 12 blocks the holes on the water leakage plate 13, thereby stopping the irrigation of water and fertilizer; the whole process is precise and efficient, effectively avoiding the waste of water and fertilizer and the damage to the soil environment caused by excessive irrigation.

[0031] Reference Figure 1 and Figure 2The mixing mechanism 2 includes a mounting frame 201, the bottom of which is fixedly connected to the top right side of the support platform 3, a driving pulley 202 is fixedly connected to the left side of the outer wall of the rotating rod 8, a driven pulley 204 is rotatably connected to the left side of the mounting frame 201, the driving pulley 202 is transmission-connected to the driven pulley 204 through a connecting belt 205, a driving bevel gear 206 is fixedly connected to the left side of the driven pulley 204, a driven bevel gear 207 is rotatably connected to the bottom of the left side of the mounting frame 201, the driving bevel gear 206 is meshedly connected to the driven bevel gear 207, and a stirring blade 203 is fixedly connected to the bottom of the driven bevel gear 207;

[0032] Specifically, the rotation of the rotating rod 8 drives the rotation of the driving pulley 202, and this rotation is achieved through direct physical contact; the driving pulley 202 is a key component of the transmission equipment, and its rotation speed and direction directly affect the operation of the entire equipment; as the driving pulley 202 rotates, the connecting belt 205 starts to work; the connecting belt 205 is a bridge between the driving pulley 202 and the driven pulley 204, and it transmits the rotational power from the driving pulley 202 to the driven pulley 204 through friction; this transmission method is both stable and reliable, ensuring that the driven pulley 204 can rotate at the same speed and direction as the driving pulley 202; the rotation of the driven pulley 204 further The meshing transmission between the active bevel gear 206 and the driven bevel gear 207 is the core part of this device. The design of the bevel gear enables the rotational power to be transmitted vertically, thereby realizing the conversion from horizontal to vertical direction. This conversion is crucial for the rotation of the stirring blade 203, because it requires vertical power to complete the task of stirring and mixing. Finally, through the meshing transmission of the active bevel gear 206 and the driven bevel gear 207, the stirring blade 203 starts to rotate. This rotation action not only realizes the mixing of water and fertilizer, but also in the whole process, the rotation speed of the stirring blade 203 is synchronized with the speed of discharging water and fertilizer, thereby ensuring the uniformity and efficiency of mixing.

[0033] Reference Figure 1 and Figure 2 Universal wheels 5 are installed at the four corners of the bottom of the base 1; a sealing ring 17 is installed on the outer wall of the rotating rod 8; and a reinforcing rib 4 is fixedly connected to the bottom of the support 3;

There is no need for manual weighing irrigation, which is time-saving and labor-saving and can meet the needs of use. During irrigation, water and fertilizer are discharged through the drain pipe 23 and the nozzle 22 to complete the irrigation work. When the drip irrigation method needs to be changed, the nozzle 22 can be disassembled and the drain pipe 23 can be connected to the drip irrigation pipeline equipment, which increases the diversity of irrigation methods and thus increases the use effect. The rotation of the rotating rod 8 is linked to the rotation of the active pulley 202, and the rotation of the active pulley 202 is linked to the driven pulley 204 through the connecting belt 205. The rotation of the driven pulley 204 is linked to the active bevel gear 206, so that the active bevel gear 206 and the driven bevel gear 207 are meshed and driven to rotate the stirring blade 203, and the stirring and mixing process can be carried out simultaneously when the water and fertilizer are discharged, which brings convenience to use.
