The short column drives the chamfer plate to rotate. During the rotation of the chamfer plate, the spring presses tightly against the horizontal strip, allowing the chamfer plate to rotate tightly against the shell wall, thereby preventing the nutrient solution residue attached to the inner wall of the shell from causing corrosion damage to the inside of the shell.

[0018] (3) The present invention sets a scraping device so that the ring block and the thin rod cooperate with the plate. During the rotation of the plate, the plate scrapes off the nutrient solution residue at the corner of the shell, preventing a large amount of nutrient solution residue from accumulating at the corner of the shell, which may cause the corner of the shell to be easily aged and damaged.

[0019] (4) The present invention sets up an anti-foaming device, so that the straight ring block, the square plate and the circular frame cooperate with the filter screen, and the circular frame drives the filter screen to rotate. During the rotation of the filter screen, the filter screen skims off the foam above the water body and the nutrient solution, preventing a large amount of foam from accumulating in the shell and causing the spraying effect of the device to be poor.

[0020] (5) The present invention sets up an anti-foaming device so that the concave block and the short rod cooperate with the pad. During the rotation of the circular frame, the short rod can support the circular frame, so that the circular frame will not vibrate violently during rotation, thereby preventing the circular frame from vibrating violently during rotation, which will cause the skimming effect of the device to be poor.

The nutrient solution enters the shell 3, a round shell 8 is fixed on the left side of the shell 3, and a motor 9 is fixedly installed on the right side of the inner wall of the round shell 8. A round rod 10 is penetrated and rotatably installed on the right side of the inner wall of the shell 3, and the left end of the round rod 10 is fixedly connected to the right end of the rotating shaft of the motor 9. Two discs 11 are fixed on the outer wall of the round rod 10, and a number of U-shaped strips 12 are embedded in the outer wall of the disc 11. The U-shaped strips 12 are used to stir the water and nutrient solution in the round shell 8. It also includes a square shell 13, which is fixedly installed on the outer wall of the graphene electric heater 1, and the outer wall of the temperature sensor 2 penetrates and is fixedly connected to the top end of the square shell 13. The outer wall of the shell 3 penetrates and is fixedly connected to the bottom end of the square shell 13. A number of air outlets are opened on the back of the square shell 13. A circular opening is provided in the middle of the front of the shell 13, and a circular cover 14 is fixedly installed on the front of the square shell 13. The circular cover 14 is used to prevent foreign matter from entering the square shell 13. An electric fan 16 is fixedly installed on the back of the circular cover 14. A vertical frame 15 is fixed to the bottom of the electric fan 16. The bottom of the vertical frame 15 is fixedly connected to the bottom end of the shell 3. The vertical frame 15 is used to support the electric fan 16. The water inlet pipe 6 and the feed pipe 7 are located above the round rod 10. A connecting piece is fixed to the right side of the water inlet pipe 6 and the feed pipe 7 respectively. A number of heat dissipation ports are provided on the outer wall of the round shell 8. The graphene electric heater 1 is located behind the electric fan 16. The electric-controlled spray head 5 is located below the back of the air outlet of the square shell 13. The round rod 10 is positively charged in the shell 3. The round rod 10 drives the disc 11 to rotate forward, and the disc 11 drives the U-shaped strips 12 to rotate forward. The U-shaped strips 12 stir the water and nutrient solution in the shell 3 to mix the water and nutrient solution evenly. The graphene electric heater 1 transfers heat to the shell 3, and the shell 3 transfers heat to the water and nutrient solution, thereby increasing the heat of the water and nutrient solution and reducing the heat energy waste of the device. The evenly mixed water and nutrient solution enter the L-shaped tube 4, and the electrically controlled spray head 5 on the L-shaped tube 4 sprays a mist mixed with the water and nutrient solution. The air outlet of the square shell 13 blows out hot air to blow the mist farther, thereby avoiding the uneven mixing of the water and nutrient solution when the intelligent heating device of the sunlight greenhouse is heating, resulting in poor wetting effect on the plant surface.

[0032] The outer wall of the round rod 10 is provided with a scraper device 17 for scraping off the nutrient solution residue attached to the inner wall of the shell 3 . The outer wall of the scraper device 17 is provided with an anti-foaming device 18 for skimming off the foam of the mixed liquid in the shell 3 .

[0033] Since it is difficult to mix water and nutrient solution evenly, it is easy to cause uneven fertilizer content in plants. When using this device, the square shell 13 supports the vertical frame 15, and the operator starts the electric fan 16 on the vertical frame 15 through the remote control. The blades on the electric fan 16 start to rotate. At this time, the gas in the solar greenhouse enters from the round mouth, and the round cover 14 on the square shell 13 prevents foreign matter from entering the square shell 13. The temperature sensor 2 senses the real-time temperature of the solar greenhouse. The temperature sensor 2 has a built-in sound alarm. When the temperature in the solar greenhouse is low, the temperature sensor 2 sends an alarm signal through the sound alarm, and the operator starts the graphene electric heater 1 through the remote control. , the graphene electric heater 1 converts electrical energy into heat and dissipates it due to its excellent thermal conductivity. At the same time, the blades on the electric fan 16 blow air to the front of the graphene electric heater 1, and the air flow heated by the graphene electric heater 1 is discharged from the air outlet of the square shell 13. The shell 3 is mounted under the graphene electric heater 1, and the water body is input through the water inlet pipe 6 on the shell 3, and the nutrient solution is input through the feed pipe 7 on the shell 3. The water body and the nutrient solution enter the round shell 8. At the same time, the operator starts the motor 9 with a remote control, and the rotating shaft of the motor 9 starts to rotate forward. The rotating shaft of the motor 9 drives the round rod 10 to rotate forward. The round rod 10 rotates forward in the shell 3, and the round rod 10 drives the round disc 11 to rotate forward. The disk 11 drives the U-shaped strips 12 to rotate forward, and the U-shaped strips 12 stir the water and nutrient solution in the shell 3 to mix the water and nutrient solution evenly. The graphene electric heater 1 transfers heat to the shell 3, and the shell 3 transfers heat to the water and nutrient solution, thereby increasing the heat of the water and nutrient solution and reducing the heat energy waste of the device. The evenly mixed water and nutrient solution enter the L-shaped tube 4, and the electric-controlled spray head 5 drives the armature through the electromagnet to act on the piston rod to perform high-speed reciprocating motion, forming an air suction phenomenon, thereby sucking the liquid out of the container. This motion generates high pressure, which is sprayed out at high speed and atomized by the nozzle. The electric-controlled spray head 5 on the L-shaped tube 4 sprays a mixture of water and nutrient solution. The water mist is blown out by the air outlet of the square shell 13, and the hot air is blown away by the water mist to a farther place. When the solar greenhouse is heated in winter, the water in the solar greenhouse evaporates quickly, the environment in the solar greenhouse is not humid enough, and the water on the surface of the plants is lost. The solar greenhouse intelligent heating device can release water containing nutrient solution when heating, so that the surface of the plants can be kept moist while applying nutrient solution, thereby allowing the plants to grow more favorably, preventing the water and nutrient solution from being mixed unevenly when the device is in use, thereby avoiding the problem of poor effect of wetting the surface of the plants due to uneven mixing of water and nutrient solution when the solar greenhouse intelligent heating device is heating.

[0034] See also Figures 1-8 On the basis of the above embodiment, in another embodiment of the present invention, the scraping device 17 includes a cross ring frame 171, the cross ring frame 171 is fixed on both sides of the outer wall of the round rod 10, and a horizontal plate 172 is slidably installed on the inner wall of the cross ring frame 171.

A short column 174 is fixed on the side of the horizontal plate 172 away from the spring 173. A chamfered plate 175 is embedded on the side of the short column 174 away from the horizontal plate 172. The spring 1 The elastic force of 73 is used to squeeze the chamfered plate 175, so that the chamfered plate 175 fits more closely to the inner wall of the shell 3. The horizontal plate 172 drives the short column 174 to rotate forward, and the short column 174 drives the chamfered plate 175 to rotate forward. During the rotation of the chamfered plate 175, the spring 173 presses tightly against the horizontal plate 172, so that the chamfered plate 175 rotates tightly against the wall of the shell 3, thereby preventing the nutrient solution residue attached to the inner wall of the shell 3 from causing corrosion damage to the inside of the shell 3 when the solar greenhouse intelligent heating device is heating.

[0035] A ring block 176 is fixed to the outer wall of the short column 174, and a thin rod 177 is fixed on the side of the ring blocks 176 away from each other.

The plate 178 is used to scrape off the nutrient solution residue at the corner of the shell 3. The thin rod 177 drives the plate 178 to rotate forward. During the rotation process, the plate 178 scrapes off the nutrient solution residue at the corner of the shell 3 to avoid the accumulation of a large amount of nutrient solution residue at the corner of the shell 3 when the solar greenhouse intelligent heating device is heating, which makes the corner of the shell 3 easy to age and damage.

The left and right sides of the circular frame 183 are provided with notches, and a filter screen 184 is fixed to the inner wall of the circular frame 183. The circular frame 183 drives the filter screen 184 to rotate forward. During the rotation of the filter screen 184, the filter screen 184 skims off the foam above the water body and the nutrient solution, thereby avoiding the accumulation of a large amount of foam in the shell 3 when the solar greenhouse intelligent heating device is heating, resulting in poor spray effect of the device.

[0037] A concave block 185 is fixed to the inner wall of the notch of the circular frame 183, and a short rod 186 is fixed to the side of the concave block 185 close to the chamfered plate 175. The short rod 186 is used to support the circular frame 183 to improve the stability of the circular frame 183 during rotation. A pad 187 is fixed to the side of the short rod 186 away from the concave block 185, and the side of the pad 187 away from the short rod 186 is fixedly connected to the outer wall of the chamfered plate 175. During the rotation of the circular frame 183, the short rod 186 can support the circular frame 183, so that the circular frame 183 will not shake violently during rotation, thereby avoiding the circular frame 183 from shaking violently during heating when the intelligent heating device of the sunlight greenhouse rotates, resulting in poor skimming effect of the device.
