When it is necessary to irrigate the aboveground part of the plant, the rotating block 3061 rotates, and under the action of the back gear 3085 and the rack 3083, the first conical head 3055 extends downward while the circular box 301 moves upward, so that the first conical head 3055 will not be inserted into the soil, so that the equipment can irrigate both the aboveground part and the underground part of the plant.

[0022] Working principle: When greenhouse planting is carried out, the drip irrigation equipment is set on one side of each plant, and the water inlet pipe 303 is connected to the main water pipe through a hose to facilitate water input for drip irrigation. In the original state, the first baffle 3062 and the second baffle 3063 are respectively located on the side where the water inlet pipe 303 and the connecting groove 304 are away from each other. When water enters the interior of the circular box 301 from the water inlet pipe 303, it impacts one side of the first baffle 3062, pushing the rotating block 3061 to rotate, so that the sliding rod 3064 moves along the semi-annular guide groove 3065. When the sliding rod 3064 moves from the top end of the semi-annular guide groove 3065 to the bottom end of the semi-annular guide groove 3065, the first baffle 3062 and the sliding rod 3064 on the rotating block 3061 move to the same side of the water inlet pipe 303 and the connecting groove 304, so that the subsequent incoming water can pass through the circular box 301 and the connecting groove 304 into the bottom pipe 302; When drip irrigation is performed on the plant roots in order to reduce water evaporation, the rotating block 3061 is rotated during the water inlet process until the water inlet pipe 303 is connected to the connecting groove 304. During this process, the rotating block 3061 rotates and drives the sliding rod 3064 to move along the semi-annular guide groove 3065. Then, the connecting rod 3069 between the two fixed shafts 3068 pushes the sliding block 3067 to move downward along the longitudinal guide groove 3066, thereby pushing the movable tube 3052 downward, so that the first conical head 3055 is inserted downward into the soil, allowing water to directly enter the soil for drip irrigation of the root system, effectively reducing water evaporation; When the first conical head 3055 is inserted into the soil, the second conical head 3072 is installed on the outside of the first conical head 3055, and the second water outlet hole 3073 is staggered with the first water outlet hole 3056 to prevent soil from entering the first water outlet hole 3056 and causing blockage during the insertion process. After the sliding block 3067 contacts the top plate 30712, it pushes the screw 30711 to move downward, and the screw 30711 is threadedly connected to the screw barrel 3079, thereby driving the top gear 30710 to rotate, and the top gear 30710 is engaged with the gear ring 3075, thereby driving the gear ring 3075 to rotate a certain angle, so that the second water outlet hole 3073 on the second conical head 3072 moves to a position corresponding to the first water outlet hole 3056 on the first conical head 3055, thereby facilitating water drip irrigation; When drip irrigation is required for the above-ground part of the plant, the staff energizes the electromagnet 30811, causing the electromagnet 30811 to generate a repulsive force on the magnetic block 30810, pushing the back gear 3085 toward the side of the vertical support plate 2, so that the back gear 3085 is engaged with the rack 3083. When the rotating block 3061 rotates due to water inflow, while driving the first conical head 3055 to move downward, the circular box 301 itself moves upward along the slide groove 3082, so that the first conical head 3055 will not be inserted into the soil, thereby drip irrigation of the above-ground part of the plant is carried out, which is convenient for drip irrigation at different positions.

7. A drip irrigation method for greenhouse planting, using the drip irrigation equipment for greenhouse planting according to claim 6, characterized in that: The steps include: S1. Water flows into the circular box from the water inlet pipe, pushing the rotating block to rotate, and pushing the movable tube downward through the connecting rod, so that the first conical head is inserted into the soil; S2, after the sliding block moves downward along the longitudinal guide groove, it pushes the screw to move downward, and drives the second conical head to rotate to the position where the second water outlet corresponds to the first water outlet through the top gear and the gear ring, so that water can be discharged to irrigate the underground part of the plant; S3. The electromagnet is energized to engage the back gear with the rack. When the rotating block rotates, the movable tube extends downward and the circular box moves upward along the slide, so that the first cone head remains on the ground to irrigate the above-ground part of the plant.
