The lower surface of the heat conducting plate 41 is fixedly connected to a heating tube 42. Both ends of the heating tube 42 are opened and sealed. The material of the heating tube 42 and the material of the heat conducting plate 41 are both stainless steel. The heating mechanism can also be installed on both sides of the spray water pipe 3, so as to increase the utilization efficiency of the heating mechanism.

[0039] In order to control the spray mechanism, a mounting plate 33 is fixedly connected to the outer surface of the insulation sleeve 31. The cross-section of the mounting plate 33 is L-shaped. A rack 34 is slidably connected to the inner top wall of the mounting plate 33. A gear 35 is rotatably connected to the outer wall surface of the insulation sleeve 31 through a rotating shaft. The gear 35 and the rack 34 are both located on the inner side of the mounting plate 33. The lower surface of the rack 34 is meshed with the upper end of the gear 35 through a latching tooth. The insulation sleeve 31 is used to wrap the spray water pipe 3, thereby preventing the external temperature from affecting the water in the spray water pipe 3. The rack 34 can also be movably installed on the inner side of the mounting plate 33 through a guide rail, thereby facilitating the directional movement of the rack 34. The lower end of the gear 35 is fixedly connected to an extrusion rod 36, and the upper end of the extrusion rod 36 is integrated with the lower end of the gear 35. The extrusion rod 36 is located on one side of the connecting hose 32, and the connecting hose 32 is extruded by the deflection of the extrusion rod 36, so as to facilitate the obstruction of the water flow in the connecting hose 32.

A temperature sensor is installed in the spray water pipe 3, and the temperature sensor is connected to the electric push rod 37, so as to facilitate the control of the operation of the electric push rod 37.

[0040] In order to spray the crops, a water outlet pipe 39 is fixedly connected to the lower end of the insulation sleeve 31 and the lower end of the heating pipe 42. The upper ends of the two water outlet pipes 39 are connected to the interior of the heating pipe 42 and the interior of the spray water pipe 3 respectively. The lower end of the water outlet pipe 39 is funnel-shaped, and a spray head 310 is slidably connected to the lower end of the water outlet pipe 39. Different spray heads 310 are installed on the heating pipe 42 and the spray water pipe 3 respectively, so as to facilitate the control of the circulation of water in the heating pipe 42 and the spray water pipe 3. The outer surfaces of two adjacent spray heads 310 are fixedly sleeved with an extrusion plate 311, the upper surface of the extrusion plate 311 is slidably connected to the lower end of the extrusion rod 36, and the upper surface of the extrusion plate 311 is fixedly connected with a tension spring 312. The tension spring 312 is used to push the spray head 310 downward, thereby facilitating the control of the movement of the spray head 310. A rubber sleeve can also be wrapped between the spray head 310 and the water outlet pipe 39, thereby facilitating the reduction of spray water leakage between the spray head 310 and the water outlet pipe 39.

[0041] By installing a heating mechanism on one side of the spray water pipe 3, the heat collecting plate 4 in the heating mechanism is used to preheat the heating pipe 42 through solar energy, and the spray water pipe 3 and the heating pipe 42 are connected through multiple connecting hoses 32. When the connecting hoses 32 are unblocked, the water in the spray water pipe 3 enters the heating pipe 42 for heating, and the flow rate is reduced through multiple branch pipes to improve the heating efficiency, so that the spray water is heated, thereby making it easier to increase the temperature of the spray water and facilitate absorption by crops.

[0042] In order to install the spray head 310, an insulation sleeve 43 is fixedly sleeved on the outer surface of the heating tube 42, and a top plate 44 is fixedly connected to the outer wall surface of the insulation sleeve 43. The inner wall of the upper end of the top plate 44 is sleeved with the outer surface of the connecting hose 32, and the lower surface of the top plate 44 is fixedly connected to the upper end of the tension spring 312. While the connecting hose 32 is wrapped and protected by the top plate 44, the tension spring 312 is installed, so as to facilitate pushing the extrusion plate 311 at the lower end of the tension spring 312. The inner side walls of the upper ends of the two spray heads 310 are fixedly connected with telescopic rods 45. The upper ends of the two telescopic rods 45 are respectively fixedly connected to the inner top wall of the heating tube 42 and the inner top wall of the spray water pipe 3, and the spray head 310 is movably installed by using the telescopic rods 45 , so that the sprinkler head 310 can be lifted and lowered at the lower end of the water outlet pipe 39. A sealing gasket 46 is fixedly sleeved on the outer surface of the lower end of one of the telescopic rods 45. A dislocation ring 47 is fixedly connected to the inner side wall of the lower end of one of the water outlet pipes 39. The sealing gasket 46 is located directly above the dislocation ring 47. The sealing gasket 46 is located below the spray water pipe 3. The sealing gasket 46 is located above the dislocation ring 47, so that it is convenient to press down the sealing gasket 46 and press against the upper surface of the dislocation ring 47 to block the flow. A sealing plug 48 is fixedly sleeved on the outer surface of the lower end of the other telescopic rod 45. The sealing plug 48 is located below the heating pipe 42. The sealing plug 48 is truncated cone-shaped and fits with the lower end of the water outlet pipe 39, so that it is convenient to rise through the sealing plug 48 to block the water outlet pipe 39.

[0043] By installing an extrusion rod 36 on the outer side of the spray water pipe 3, the deflection of the extrusion rod 36 is used to squeeze the connecting hose 32 to control the dredging of the connecting hose 32. At the same time, the lower end of the extrusion rod 36 is used to squeeze the extrusion plate 311 on the surface of the spray head 310, thereby controlling the dredging of the water outlet pipes 39 on the surfaces of the two spray heads 310, and further controlling the circulation of the spray water in different pipes.

[0044] Working principle:

[0045] Step 1: Start the electric push rod 37, which drives the rack 34 to move through the connecting rod 38, and the rack 34 drives the gear 35 and the squeezing rod 36 to deflect. After the squeezing rod 36 deflects, it squeezes and blocks the connecting hose 32. At the same time, the upper surface of the squeezing plate 311 loses the squeezing of the squeezing rod 36, and the tension spring 312 pulls the squeezing plate 311 and the two adjacent spray heads 310 to rise, and the sealing gasket 46 separates upward from the offset ring 47. The water outlet pipe 39 under the spray water pipe 3 is unblocked, and the spray water is pumped into the spray water pipe 3 and sprayed downward through the spray head 310;

[0046] Step 2: The heat collecting plate 4 absorbs solar energy to heat up, and transmits it to the heating tube 42 through the heat conducting plate 41. The heating tube 42 heats up and is insulated by the heat insulating sleeve 43. When it is detected that the water temperature in the spray water pipe 3 is too low, the electric push rod 37 is started, and the electric push rod 37 drives the rack 34 to move in the opposite direction through the connecting rod 38. The rack 34 drives the gear 35 and the extrusion rod 36 to deflect, and the surface of the connecting hose 32 loses extrusion and is unblocked, and the water tank in the spray water pipe 3 flows into the heating tube 42 through the connecting hose 32;

[0047] Step 3: The extrusion rod 36 is erected, and the lower end of the extrusion rod 36 pushes the surface of the extrusion plate 311, the tension spring 312 is stretched, and the extrusion plate 311 pushes the two adjacent spray heads 310 downward, and the spray head 310 connected to the spray water pipe 3 drives the sealing gasket 46 to squeeze the dislocation ring 47 downward, and the water outlet pipe 39 is blocked by the dislocation ring 47 and the sealing gasket 46, and the spray head 310 connected to the heating pipe 42 drives the sealing plug 48 downward to separate from the water outlet pipe 39, and the water outlet pipe 39 at the lower end of the heating pipe 42 is unblocked;

[0048] Step 4: The water in the spray water pipe 3 enters the heating pipe 42 through the connecting hose 32 and exchanges heat with the heating pipe 42 to increase the temperature. After the water in the heating pipe 42 is heated, it is sprayed downward through the water outlet pipe 39 and the spray head 310 below.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
