Description

Technical Field

[0001] This invention relates to the field of greenhouse irrigation equipment technology, specifically to an integrated intelligent irrigation system for greenhouses that combines water, fertilizer, air, and heat. Background Technology

[0002] A greenhouse is a building that can control or partially control the plant growth environment. It is mainly used for non-seasonal or non-regional plant cultivation, scientific research, generational breeding, and ornamental plant cultivation.

[0003] Because greenhouses are enclosed spaces, rainwater cannot fall inside. Therefore, the plants inside need irrigation. If irrigation pipes are installed on the roof of the greenhouse, they can only spray water, not liquid fertilizer, as liquid fertilizer falling on the plant leaves will harm the plants. If irrigation pipes are installed on the ground to directly water the plant roots, the ground-level irrigation pipes will affect the cultivation and weeding of the plants. In addition, at low temperatures, a large amount of condensation will form on the inner walls of the greenhouse. These condensation droplets will affect the light inside the greenhouse and the growth of the plants. Furthermore, the internal temperature of the greenhouse is prone to fluctuations depending on the time of day, which is also not conducive to the rapid growth of the plants. Therefore, the internal temperature of the greenhouse needs to be controlled according to the situation. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing systems and provide an integrated intelligent irrigation system for greenhouses, combining water, fertilizer, air, and heat. The irrigation pipes are installed at the top of the greenhouse and can be lowered to near the ground as needed. Water and liquid fertilizer can be sprayed from the pipes. Water spraying avoids hitting plant flowers, directly watering the plant roots. Liquid fertilizer spraying avoids falling onto plant leaves and harming the plants. When irrigation is not needed, the system is retracted to the top of the greenhouse, without affecting cultivation or weeding. It can also humidify the greenhouse and control the temperature, ensuring manageable temperature and humidity to promote plant growth. Furthermore, it can handle the large amount of condensation on the greenhouse walls at low temperatures, increasing the amount of light within the greenhouse and facilitating rapid and healthy plant growth. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a greenhouse integrated water, fertilizer, air, and heat intelligent irrigation system, comprising a roof-mounted walking mechanism, wherein the roof-mounted walking mechanism includes end plates, guide rods, a walking seat block, and a longitudinal moving force assembly. Two end plates are provided and arranged correspondingly front and rear, and two longitudinal guide rods are provided between the two end plates. Two sliding slots on the walking seat block are longitudinally slidably connected to the two guide rods. The walking seat block is connected to the longitudinal moving force assembly, and further includes:

[0006] The irrigation swing control mechanism includes a synchronous swing power component, a swing arm, and a transverse slide groove. The synchronous swing power component is installed in the middle of the traveling block. Two swing arms are connected to the bottom of the synchronous swing power component, and each swing arm is provided with a transverse slide groove.

[0007] A multi-functional atomizing humidification mechanism includes an electric telescopic rod II, an atomizing rigid tube, atomizing nozzles, and an atomizing water delivery assembly. The fixed end of the electric telescopic rod II is fixedly connected to one end of the horizontal sliding groove near the walking seat block. The telescopic end of the electric telescopic rod II is connected to one end of the atomizing rigid tube. The atomizing rigid tube is slidably connected to the horizontal sliding groove, and the other end of the atomizing rigid tube extends to the outside of the end of the horizontal sliding groove. Atomizing nozzles are evenly spaced at the bottom of the atomizing rigid tube. The atomizing rigid tube is connected to the atomizing water delivery assembly.

[0008] The water and fertilizer irrigation mechanism is installed at the end of the atomizing hard tube away from the walking seat block.

[0009] The end plates and guide rods form a frame, which is installed on the top of the greenhouse. The two end plates, with their opposite sides located on the front and rear outer sides of the greenhouse top, respectively, are positioned on the top. The longitudinal motion component drives the walking block to move back and forth along the guide rod, allowing the walking block to move back and forth within the greenhouse top. This enables the multi-functional atomizing humidification mechanism and the water and fertilizer irrigation mechanism to provide comprehensive humidification and irrigation within the greenhouse. The synchronous swinging power component drives the two swing rods to move synchronously closer or further apart, i.e., to simultaneously bring the two swing rods into a horizontal or vertical state. When in the horizontal position, the two swing arms are parallel to each other, and the horizontal sliding groove on the swing arms is used to limit the atomizing hard tube, so that the atomizing hard tube can only slide along the direction of the swing arm. The electric telescopic rod can push the atomizing hard tube to move within the horizontal sliding groove. When the two swing arms are in the horizontal position at the same time, the atomizing nozzle on the atomizing hard tube is set downward, and the atomizing water delivery component delivers water into the atomizing hard tube. The water in the atomizing hard tube is atomized and sprayed out through the atomizing nozzle, which can increase the humidity in the greenhouse. When the two swing arms are in the vertical position at the same time, the water and fertilizer irrigation mechanism can be close to the ground to spray water or liquid fertilizer on the roots of plants and directly irrigate the plant roots.

[0010] Furthermore, the synchronous swing power assembly includes a rectangular frame, a guide protrusion, an electric telescopic rod, a guide vertical rod, a double-sided rack, a gear seat, and gears. The middle of the walking block has a vertical groove, and the top of the walking block is fixedly connected to the rectangular frame by bolts. The bottom center of the rectangular frame has a guide protrusion, and the guide vertical rod is vertically slidably connected in the guide groove in the middle of the guide protrusion. The top of the guide vertical rod is connected to the top of the rectangular frame through the electric telescopic rod. The bottom end of the guide vertical rod is fixedly connected to the top of the double-sided rack, which passes through the middle of the vertical groove. Two gear seats are fixedly connected to the bottom two sides of the walking block, and two gear seats are rotatably connected to two gears. The two gears mesh with the two sides of the double-sided rack, and the two gears are fixedly connected to one end of the two swing rods. The guide groove in the middle of the guide protrusion limits the guide vertical rod, allowing the guide vertical rod and the double-sided rack to move only up and down. When the electric telescopic rod extends, it drives the double-sided rack to descend through the guide vertical rod. The meshing of the double-sided rack with the two gears drives the two swing arms to move away from each other synchronously until the two swing arms are in a horizontal state. When the electric telescopic rod shortens, it drives the double-sided rack to rise through the guide vertical rod. The meshing of the double-sided rack with the two gears drives the two swing arms to move closer to each other synchronously until the two swing arms are in a vertical state.

[0011] Furthermore, the water and fertilizer irrigation mechanism includes a support, a movable shaft, an irrigation hard pipe, an irrigation head, an electric telescopic rod, and an irrigation water delivery assembly. The end of the atomizing hard pipe away from the walking seat block is fixedly connected to the support. The support is movably connected to one end of the irrigation hard pipe through a longitudinal movable shaft. Irrigation heads are arranged at equal intervals on the irrigation hard pipe. The part of the atomizing hard pipe located outside the transverse sliding groove is movably connected to one end of the electric telescopic rod. The other end of the electric telescopic rod is movably connected to the irrigation hard pipe. The irrigation hard pipe is connected to the irrigation water delivery assembly.

[0012] When the two swing arms are in a vertical position, the electric telescopic rod three pushes the irrigation hard pipe to move relative to the support through the movable shaft until the irrigation hard pipe is perpendicular to the two swing arms and the atomizing hard pipe. At this time, the irrigation head on the irrigation hard pipe is set downward. If the height of the irrigation head spraying water or liquid fertilizer is still too high, in order to avoid water or liquid fertilizer falling on the plant leaves, the electric telescopic rod two extends and pushes the atomizing hard pipe downward along the horizontal sliding groove on the swing arm, so that the irrigation hard pipe is close to the ground.

[0013] If the irrigation position needs to be changed, the electric telescopic rod 2 shortens, and the roof walking mechanism moves forward or backward a distance to allow the horizontal irrigation pipe to pass over a row of watered plants. Then the electric telescopic rod 2 extends again to bring the irrigation pipe close to the ground again. If the electric telescopic rod 2 is shortened to its shortest length and the irrigation pipe still cannot be higher than the top of the plants, the synchronous swing power component controls the two swing rods to swing and rise to ensure that the irrigation pipe can pass over the top of the plants.

[0014] If irrigation is no longer needed, the second electric telescopic rod will first shorten, allowing the atomizing hard tube to retract into the horizontal sliding groove. Then, the third electric telescopic rod will shorten, allowing the irrigation hard tube to fold close to the swing arm. Finally, the synchronous swing power component will control the two swing arms to move to a horizontal state.

[0015] Furthermore, it also includes a pneumatic airflow control mechanism, which comprises a curved frame, a mounting slot, a pneumatic shaft, a pneumatic arm, and a pneumatic power assembly. Two curved frames are fixedly connected to the left and right sides of the rectangular frame, each curved frame having a mounting slot. Each mounting slot is movably connected to the middle of a pneumatic arm via a longitudinal pneumatic shaft. A pneumatic power assembly is connected to one end of each pneumatic arm near the rectangular frame. The pneumatic arm is connected to a demisting airflow heating mechanism. The pneumatic power assembly drives the pneumatic arm to move within the mounting slot via the pneumatic shaft, thereby changing the pneumatic angle of the airflow from the demisting airflow heating mechanism.

[0016] Furthermore, the demisting and heating mechanism includes an air pump, a flexible air tube, a heating chamber, and an airflow guide box. Heating chambers are respectively opened in the two pitch arms. The ends of the two heating chambers near the rectangular frame are respectively connected to one end of the two flexible air tubes. The other ends of the two flexible air tubes are respectively connected to the air outlet of the air pump. The air pump is installed on the walking seat block. The ends of the two pitch arms away from the rectangular frame are respectively fixedly connected to two airflow guide boxes. An air pump blows air into the heating chamber through a flexible air tube. The airflow inside the heating chamber is then blown out through an airflow guide box. When a large number of mist droplets appear on the lower side of the transparent roof of the greenhouse structure, affecting the plants' access to light, the airflow guide box blows airflow towards the mist droplets, causing them to slide down the lower side of the transparent roof. The pitch power component continuously adjusts the pitch of the pitch arm and the airflow guide box, thereby performing a comprehensive mist droplet blowing operation on the lower side of the transparent roof. This method of mist droplet treatment is suitable for treating mist droplets on the lower side of different transparent roofs, especially for situations where the support structure on the lower side of the transparent roof is complex. It relies on airflow to blow down the mist droplets without interference from the support structure on the lower side of the transparent roof.

[0017] Furthermore, the defogging and heating mechanism also includes heating wires, with a spiral heating wire installed in each heating chamber. The heating wires heat the airflow passing through the heating chamber, allowing the airflow guide box to blow out hot air, which can heat the temperature inside the greenhouse, adjust the low temperature inside the greenhouse, and at the same time, the hot air also helps to evaporate the fog droplets under the transparent roof.

[0018] Furthermore, the demisting and heating mechanism also includes an opening and closing shaft, an opening and closing plate, and a torsion spring. Each airflow guide box is movably connected to one side of the opening and closing plate via the opening and closing shaft. The opening and closing plate is correspondingly positioned at the end of the heating chamber. A torsion spring is sleeved at the end of the opening and closing shaft, and the two ends of the torsion spring are respectively connected to the opening and closing plate and the airflow guide box. When the humidity in the greenhouse is high, it will cause rapid corrosion of the heating wire, requiring frequent replacement of the heating wire. Therefore, a torsion spring is provided. The torsion force of the torsion spring causes the opening and closing plate to close the end of the heating chamber. When the air pump blows air into the heating chamber through the flexible air tube, the airflow force overcomes the torsion force of the torsion spring, causing the opening and closing plate to open the end of the heating chamber, allowing the airflow guide box to blow air normally. When the air pump stops working, the torsion spring drives the opening and closing plate to close the end of the heating chamber again, protecting the heating wire.

[0019] Furthermore, the system also includes a droplet scraping mechanism, which comprises a square rod, a spring, mounting strips, and a droplet scraping adhesive strip. Two square rods are vertically slidably connected to two square holes on either side of the top of the rectangular frame. Two mounting strips are fixedly connected to the opposite sides of the tops of the two square rods, each with a detachable droplet scraping adhesive strip. A spring is sleeved on the section of the square rod between the mounting strips and the rectangular frame, with the upper and lower ends of the spring connected to the mounting strips and the rectangular frame, respectively. As the rectangular frame moves back and forth with the traveling block, the droplet scraping adhesive strip on the mounting strip scrapes away droplets on the underside of the transparent roof, preventing the droplets from affecting the light inside the greenhouse. The spring pushes the square rod upwards, causing the top of the droplet scraping adhesive strip to adhere tightly to the underside of the transparent roof. Because it directly contacts the transparent roof, this method is suitable for cases where the support structure under the transparent roof is simple. This scraping method is highly efficient at handling droplets, and the droplet scraping adhesive strip is deformable and replaceable.

[0020] Furthermore, the mist removal mechanism also includes wheel seats, obstacle avoidance rollers, obstacle avoidance limiting rods, and obstacle avoidance arc protrusions. Each square rod has a wheel seat installed at its top, and an obstacle avoidance roller is rotatably installed on each wheel seat. Two longitudinal obstacle avoidance limiting rods are fixedly connected between the tops of the two end plates, and obstacle avoidance arc protrusions are fixedly connected at equal intervals at the bottoms of the two obstacle avoidance limiting rods. The two obstacle avoidance rollers are tumblingly connected to the bottoms of the two obstacle avoidance limiting rods. Because the bottom of the transparent canopy is supported by canopy support rods, which can obstruct the desiccant strip, the obstacle avoidance arc protrusion on the obstacle avoidance limit rod is set to correspond to the canopy support rod on the lower side of the transparent canopy. When the walking block moves back and forth, the obstacle avoidance roller rolls under the obstacle avoidance limit rod. When the obstacle avoidance roller encounters the obstacle avoidance arc protrusion, the square rod moves down relative to the rectangular frame, and the spring is compressed. At this time, the desiccant strip on the mounting strip moves down with the square rod, allowing the desiccant strip to move down past the canopy support rod. After the obstacle avoidance roller passes the obstacle avoidance arc protrusion, the desiccant strip also passes past the canopy support rod, the spring returns to its original position and extends, and the top of the desiccant strip re-contacts the lower side of the transparent canopy.

[0021] Furthermore, the system also includes a greenhouse ventilation and cooling mechanism. This mechanism comprises a circular channel, an inlet fan, an exhaust fan, and a circular channel sealing assembly. Two circular channels are respectively formed on the top of the two end plates. An inlet fan is installed in one of the channels, blowing air inwards towards the inside of the end plate. An exhaust fan is installed in the other channel, blowing air outwards towards the outside of the end plate. Two circular channel sealing assemblies are installed on the opposite sides of the two end plates. When the temperature inside the greenhouse is too high, the circular channel sealing assembly opens both channels, and the inlet and exhaust fans operate simultaneously. The inlet fan blows cold air into the greenhouse, while the exhaust fan blows hot air outwards, thus lowering the temperature inside the greenhouse.

[0022] Compared with existing technologies, the beneficial effects of this integrated water, fertilizer, air, and heat intelligent irrigation system for greenhouses are:

[0023] 1. The irrigation pipes are installed at the top of the greenhouse. As needed, the irrigation pipes can be lowered to near the ground. Water and liquid fertilizer can be sprayed in the irrigation pipes. Spraying water can prevent water from hitting the plant flowers and watering the plant roots directly. When spraying liquid fertilizer, it can prevent liquid fertilizer from falling on the plant leaves and damaging the plant. When irrigation is not needed, it can be stored at the top of the greenhouse without affecting the cultivation and weeding of plants.

[0024] 2. The atomizing water delivery component delivers water into the atomizing hard tube. The water in the atomizing hard tube is atomized and sprayed out through the atomizing nozzle, which can increase the humidity in the greenhouse and provide humidification through spraying.

[0025] 3. The heating wire heats the airflow passing through the heating chamber, allowing the airflow guide box to blow out hot air, which can heat the temperature inside the greenhouse and adjust the low temperature inside the greenhouse. At the same time, the hot air also helps to evaporate the fog droplets under the transparent roof. When the temperature inside the greenhouse is too high, the round slot sealing component opens two round slots, and the inlet fan and exhaust fan work simultaneously. The inlet fan blows cold air into the greenhouse, and the exhaust fan blows hot air out of the greenhouse, reducing the temperature inside the greenhouse and thus controlling the temperature inside the greenhouse.

[0026] 4. As the rectangular frame moves back and forth with the walking block, the drip removal strip on the mounting strip can remove the drips on the underside of the transparent canopy, preventing the drips from affecting the light inside the greenhouse, increasing the amount of light inside the greenhouse, and helping the plants to receive light and grow quickly and well.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1, please refer to Figures 1 to 10 This embodiment provides a technical solution: a greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system, including a roof walking mechanism 1. The roof walking mechanism 1 includes an end plate 11, a guide rod 12, a walking seat block 15 and a longitudinal moving force component. There are two end plates 11, which are arranged in a front-to-back correspondence. Two longitudinal guide rods 12 are arranged between the two end plates 11. Two sliding through slots on the walking seat block 15 are longitudinally slidably connected to the two guide rods 12. The walking seat block 15 is connected to the longitudinal moving force component.

[0040] The longitudinal motion assembly includes a travel screw 13, a travel motor 14, and a screw nut 16. The longitudinal travel screw 13 is rotatably connected between the two end plates 11. The travel block 15 is fixedly connected to the screw nut 16 at the position corresponding to the travel screw 13. The screw nut 16 and the travel screw 13 are connected in a mating manner. The end of the travel screw 13 is fixedly connected to the output shaft of the travel motor 14. The travel motor 14 is fixedly installed on the outside of the corresponding end plate 11. When the travel motor 14 is working, it drives the travel screw 13 to rotate clockwise. The thread action between the travel screw 13 and the screw nut 16 drives the travel block 15 to move forward along the guide rod 12. When the travel motor 14 is working, it drives the travel screw 13 to rotate counterclockwise, and the travel block 15 moves backward along the guide rod 12.

[0041] It also includes an irrigation swing control mechanism 2, a multi-functional atomizing humidification mechanism 3, and a water and fertilizer irrigation mechanism 4;

[0042] The irrigation swing control mechanism 2 includes a synchronous swing power component, a swing rod 28 and a transverse slide groove 29. The synchronous swing power component is installed in the middle of the walking block 15. The bottom of the synchronous swing power component is connected to two swing rods 28, and each swing rod 28 is provided with a transverse slide groove 29.

[0043] The synchronous swing power assembly includes a rectangular frame 21, a guide protrusion 22, an electric telescopic rod 23, a guide vertical rod 24, a double-sided rack 25, a gear seat 26, and a gear 27. A vertical groove is provided in the middle of the walking block 15. The top of the walking block 15 is fixedly connected to the rectangular frame 21 by bolts. A guide protrusion 22 is provided at the bottom center of the rectangular frame 21. A guide vertical rod 24 is vertically slidably connected in the guide groove in the middle of the guide protrusion 22. The top of the guide vertical rod 24 is connected to the top of the rectangular frame 21 through the electric telescopic rod 23. The bottom end of the guide vertical rod 24 is fixedly connected to the top of the double-sided rack 25. The double-sided rack 25 passes through the middle of the vertical groove. Two gear seats 26 are fixedly connected to the bottom sides of the walking block 15. Two gear seats 26 are rotatably connected to two gears 27. The two gears 27 are meshed with the two sides of the double-sided rack 25, and the two gears 27 are fixedly connected to one end of two swing rods 28. The guide groove in the middle of the guide protrusion 22 limits the guide vertical rod 24, allowing the guide vertical rod 24 and the double-sided rack 25 to move only up and down. The electric telescopic rod 23 extends, driving the double-sided rack 25 to descend through the guide vertical rod 24. The meshing action of the double-sided rack 25 with the two gears 27 drives the two swing rods 28 to move away from each other synchronously until the two swing rods 28 are in a horizontal state. The electric telescopic rod 23 shortens, driving the double-sided rack 25 to rise through the guide vertical rod 24. The meshing action of the double-sided rack 25 with the two gears 27 drives the two swing rods 28 to move closer to each other synchronously until the two swing rods 28 are in a vertical state.

[0044] The multi-functional atomizing humidification mechanism 3 includes an electric telescopic rod 31, an atomizing hard tube 32, an atomizing nozzle 33, and an atomizing water delivery assembly. The fixed end of the electric telescopic rod 31 is fixedly connected to one end of the horizontal sliding groove 29 near the walking seat block 15. The telescopic end of the electric telescopic rod 31 is connected to one end of the atomizing hard tube 32. The atomizing hard tube 32 is slidably connected to the horizontal sliding groove 29, and the other end of the atomizing hard tube 32 extends to the outer side of the end of the horizontal sliding groove 29. Atomizing nozzles 33 are evenly arranged at the bottom of the atomizing hard tube 32. The atomizing hard tube 32 is connected to the atomizing water delivery assembly.

[0045] The atomizing water delivery assembly includes an atomizing branch pipe 34, an atomizing hose 35, and a water pump 36. Two atomizing hard pipes 32 are respectively connected to one end of an atomizing hose 35 through two atomizing branch pipes 34. The other end of the atomizing hose 35 is connected to the outlet of the water pump 36. The water pump 36 is installed at the bottom of the front end plate 11. The inlet of the water pump 36 is connected to an external water source through a pipeline. The water pump 36 pumps the external water source into the two atomizing hard pipes 32 through the atomizing branch pipes 34 and the atomizing hose 35.

[0046] The water and fertilizer irrigation mechanism 4 is installed at the end of the atomizing hard pipe 32 away from the walking seat block 15.

[0047] The water and fertilizer irrigation mechanism 4 includes a support 41, a movable shaft 42, an irrigation hard pipe 43, an irrigation head 44, an electric telescopic rod 45, and an irrigation water delivery assembly. The end of the atomizing hard pipe 32 away from the walking seat block 15 is fixedly connected to the support 41. The support 41 is movably connected to one end of the irrigation hard pipe 43 through the longitudinal movable shaft 42. Irrigation heads 44 are arranged at equal intervals on the irrigation hard pipe 43. The part of the atomizing hard pipe 32 located outside the transverse sliding groove 29 is movably connected to one end of the electric telescopic rod 45. The other end of the electric telescopic rod 45 is movably connected to the irrigation hard pipe 43. The irrigation hard pipe 43 is connected to the irrigation water delivery assembly.

[0048] The irrigation water delivery assembly includes an irrigation branch pipe 46, an irrigation hose 47, and an irrigation liquid pump 48. Two irrigation rigid pipes 43 are connected to one end of an irrigation hose 47 through the two irrigation branch pipes 46, and the other end of the irrigation hose 47 is connected to the outlet of the irrigation liquid pump 48. The irrigation liquid pump 48 is installed at the bottom of the rear end plate 11. The inlet of the irrigation liquid pump 48 is connected to a water source and a liquid fertilizer tank through two valves. The two valves can control the connection between the irrigation liquid pump 48 and the water source and the liquid fertilizer tank. The irrigation liquid pump 48 pumps water or liquid fertilizer into the two irrigation rigid pipes 43 through the irrigation branch pipes 46 and the irrigation hose 47.

[0049] Since the irrigation hose 47 and the atomizing hose 35 need to move with the walking block 15, the irrigation hose 47 and the atomizing hose 35 are very long. Therefore, hanging posts 93 and hanging rings 94 are provided to keep the irrigation hose 47 and the atomizing hose 35 in a regular position. A longitudinal hanging post 93 is provided between the two end plates 11. The hanging post 93 is slidably connected to the walking block 15. Multiple hanging rings 94 are provided at equal intervals on the irrigation hose 47 and the atomizing hose 35, and each hanging ring 94 is slidably connected to the corresponding position on the hanging post 93. With the help of the hanging post 93 and the hanging rings 94, the irrigation hose 47 and the atomizing hose 35 remain in a regular position when bending or straightening. Specifically, the irrigation hose 47 and the atomizing hose 35 are each provided with no less than four hanging rings 94.

[0050] When the two swing arms 28 are in a vertical position, the electric telescopic rod 35 pushes the irrigation hard pipe 43 to move relative to the support 41 through the movable shaft 42 until the irrigation hard pipe 43 is perpendicular to the two swing arms 28 and the atomizing hard pipe 32. At this time, the irrigation head 44 on the irrigation hard pipe 43 is set downward. If the height of the water spray or liquid fertilizer sprayed by the irrigation head 44 is still too high, in order to avoid water or liquid fertilizer falling on the plant leaves, the electric telescopic rod 21 extends and pushes the atomizing hard pipe 32 downward along the horizontal sliding groove 29 on the swing arm 28, so that the irrigation hard pipe 43 is close to the ground.

[0051] If the irrigation position needs to be changed, the electric telescopic rod 2 31 is shortened, and the roof walking mechanism 1 moves forward or backward a distance to allow the horizontal irrigation pipe 43 to pass over a row of watered plants. Then the electric telescopic rod 2 31 is extended again to bring the irrigation pipe 43 back close to the ground. If the electric telescopic rod 2 31 is shortened to its shortest length and the irrigation pipe 43 still cannot be higher than the top of the plants, the synchronous swing power component controls the two swing rods 28 to swing and rise to ensure that the irrigation pipe 43 can pass over the top of the plants.

[0052] If irrigation is no longer needed, the electric telescopic rod 21 is shortened first, allowing the atomizing hard tube 32 to retract into the horizontal sliding groove 29. Then, the electric telescopic rod 35 is shortened, allowing the irrigation hard tube 43 to fold close to the swing rod 28. Then, the synchronous swing power component controls the two swing rods 28 to move to a horizontal state.

[0053] The greenhouse roof is constructed using a greenhouse structure 10, which includes longitudinal beams 101, support rods 102, and a transparent roof 103. See details. Figure 10 The longitudinal beam 101 has equidistant canopy support rods 102 on both the left and right sides. The longitudinal beam 101 and the canopy support rods 102 form a support structure. A transparent canopy roof 103 is provided on the upper side of the support structure.

[0054] In use, the end plate 11 and the guide rod 12 form a frame, which is installed on the longitudinal beam 101 at the top of the greenhouse. The two end plates 11 are located on the front and rear outer sides of the greenhouse top, respectively. The longitudinal movement force component can drive the walking block 15 to move back and forth along the guide rod 12, allowing the walking block 15 to move back and forth at the top of the greenhouse. This allows the multi-functional atomizing humidification mechanism 3 and the water and fertilizer irrigation mechanism 4 to provide comprehensive humidification and irrigation to the greenhouse. The synchronous swinging power component is used to drive the two swing rods 28 to move closer or further apart synchronously, that is, to drive the two swing rods 28 to be in a horizontal state or in a vertical state simultaneously. When the two swing rods 28 are parallel to each other, the horizontal sliding groove 29 on the swing rod 28 is used to limit the atomizing hard tube 32, so that the atomizing hard tube 32 can only slide along the direction of the swing rod 28. The electric telescopic rod 31 can push the atomizing hard tube 32 to move within the horizontal sliding groove 29. When the two swing rods 28 are in a horizontal state at the same time, the atomizing nozzle 33 on the atomizing hard tube 32 is set downward, and the atomizing water delivery component delivers water into the atomizing hard tube 32. The water in the atomizing hard tube 32 is atomized and sprayed out through the atomizing nozzle 33, which can increase the humidity in the greenhouse. When the two swing rods 28 are in a vertical state at the same time, the water and fertilizer irrigation mechanism 4 can approach the ground and spray water or liquid fertilizer on the roots of plants to directly irrigate the roots of plants.

[0055] Example 2, please refer to Figures 1 to 10 This embodiment provides a technical solution: an integrated intelligent irrigation system for greenhouses, combining water, fertilizer, gas, and heat. This embodiment is structurally similar to Embodiment 1, with the difference being:

[0056] It also includes a blowing pitch control mechanism 6, which includes a bending frame 61, a mounting slot 62, a pitch shaft 63, a pitch arm 64, and a pitch power assembly. Two bending frames 61 are fixedly connected to the left and right sides of the rectangular frame 21, and each bending frame 61 is provided with a mounting slot 62. The middle part of the pitch arm 64 is movably connected to each mounting slot 62 through the longitudinal pitch shaft 63. The pitch power assembly is connected to one end of each pitch arm 64 near the rectangular frame 21. The pitch arm 64 is connected to a demisting blowing heating mechanism 7.

[0057] The pitch power assembly includes a semicircular plate 65, an arc-shaped groove 66, a sector-shaped slider 67, a curved arm 68, and a pitch motor 69. Each pitch arm 64 has a semicircular plate 65 fixedly connected to one end near the rectangular frame 21. An arc-shaped groove 66 is formed on the arc surface of the semicircular plate 65. A pitch motor 69 is mounted on the curved frame 61 via a motor mount. The output shaft of the pitch motor 69 is fixedly connected to one end of the curved arm 68, and the other end of the curved arm 68 is movably connected to the sector-shaped slider 67 via a curved arm shaft. The sector-shaped slider 67 is slidably connected to the arc-shaped slide groove 66. The pitch motor 69 drives the bent arm 68 to rotate. The bent arm 68 drives the sector-shaped slider 67 to rotate through the bent arm shaft. The sliding of the sector-shaped slider 67 in the arc-shaped slide groove 66 can counteract the horizontal movement of the sector-shaped slider 67. The vertical movement of the sector-shaped slider 67 can drive the pitch arm 64 to move relative to the pitch axis 63 in the mounting through groove 62 through the semi-circular plate 65, thereby allowing the end of the pitch arm 64 to pitch.

[0058] The pitch power assembly is used to drive the pitch arm 64 to move within the mounting slot 62 via the pitch shaft 63, thereby changing the pitch angle of the airflow blown out by the demisting blowing and heating mechanism 7.

[0059] The defogging and heating mechanism 7 includes an air pump 71, a flexible air tube 72, a heating chamber 73, and an airflow guide box 75. The two pitch arms 64 are each provided with a heating chamber 73. The ends of the two heating chambers 73 near the rectangular frame 21 are respectively connected to one end of the two flexible air tubes 72. The other ends of the two flexible air tubes 72 are respectively connected to the air outlet of the air pump 71. The air pump 71 is mounted on the walking seat block 15. The ends of the two pitch arms 64 away from the rectangular frame 21 are respectively fixedly connected to two airflow guide boxes 75. Air pump 71 blows air into heating chamber 73 through flexible air tube 72. The airflow in heating chamber 73 is blown out through airflow guide box 75. When a large number of fog droplets appear on the lower side of the transparent roof 103 of greenhouse structure 10, affecting the plants' access to light, airflow guide box 75 blows airflow towards the fog droplets, causing the fog droplets to slide down along the lower side of transparent roof 103. The pitch power component continuously changes the pitch calibration of pitch arm 64 and airflow guide box 75, thereby performing a comprehensive fog droplet blowing operation on the lower side of transparent roof 103. This method of fog droplet treatment is suitable for treating fog droplets on the lower side of different transparent roofs 103, especially suitable for situations where the support structure on the lower side of transparent roof 103 is complex. It relies on airflow to blow away the fog droplets without interference from the support structure on the lower side of transparent roof 103.

[0060] The defogging and heating mechanism 7 also includes heating wires 74, with each heating chamber 73 containing a spiral heating wire 74. The heating wires 74 heat the airflow passing through the heating chamber 73, allowing the airflow guide box 75 to blow out hot air, which can heat the temperature inside the greenhouse, adjust the low temperature inside the greenhouse, and at the same time, the hot air also helps to evaporate the fog droplets on the lower side of the transparent canopy 103.

[0061] The demisting and heating mechanism 7 also includes an opening and closing shaft 76, an opening and closing plate 77, and a torsion spring 78. Each airflow guide box 75 is movably connected to one side of the opening and closing plate 77 via the opening and closing shaft 76. The opening and closing plate 77 is correspondingly arranged with the end of the heating chamber 73. The end of the opening and closing shaft 76 is sleeved with a torsion spring 78, and the two ends of the torsion spring 78 are respectively connected to the opening and closing plate 77 and the airflow guide box 75. High humidity inside the greenhouse can cause rapid corrosion of the heating wire 74, requiring frequent replacement. Therefore, a torsion spring 78 is installed. The torque of the torsion spring 78 causes the opening and closing plate 77 to close the end of the heating chamber 73. When the air pump 71 blows air into the heating chamber 73 through the flexible air tube 72, the airflow overcomes the torque of the torsion spring 78, causing the opening and closing plate 77 to open the end of the heating chamber 73, allowing the airflow guide box 75 to blow air normally. When the air pump 71 stops working, the torsion spring 78 drives the opening and closing plate 77 to close the end of the heating chamber 73 again, protecting the heating wire 74.

[0062] Example 3, please refer to Figures 1 to 10 This embodiment provides a technical solution: an integrated intelligent irrigation system for greenhouses, combining water, fertilizer, gas, and heat. This embodiment is structurally similar to Embodiment Two, with the difference being:

[0063] It also includes a droplet scraping mechanism 5, which includes a square rod 51, a spring 53, a mounting strip 54, and a droplet scraping adhesive strip 55. Two square rods 51 are vertically slidably connected in two square holes on the top sides of the rectangular frame 21. Two mounting strips 54 are fixedly connected to the opposite sides of the top of the two square rods 51. A droplet scraping adhesive strip 55 is detachably installed on each mounting strip 54. A spring 53 is sleeved on the rod segment of the square rod 51 located between the mounting strip 54 and the rectangular frame 21. The upper and lower ends of the spring 53 are connected to the mounting strip 54 and the rectangular frame 21, respectively. As the rectangular frame 21 moves back and forth with the traveling block 15, the desiccant strip 55 on the mounting strip 54 can scrape off the desiccant on the underside of the transparent roof 103, preventing the desiccant from affecting the light inside the greenhouse. The spring 53 pushes the square rod 51 upward, so that the top of the desiccant strip 55 is in close contact with the underside of the transparent roof 103. Since it is in direct contact with the transparent roof 103, it is suitable for situations where the support structure under the transparent roof 103 is simple. This scraping method has high efficiency in handling desiccant, and the desiccant strip 55 can be deformed and replaced.

[0064] The mist removal mechanism 5 also includes wheel seats 52, obstacle avoidance rollers 56, obstacle avoidance limit rods 57, and obstacle avoidance arc protrusions 58. Each square rod 51 has a wheel seat 52 installed at its top, and an obstacle avoidance roller 56 is rotatably installed on each wheel seat 52. Two longitudinal obstacle avoidance limit rods 57 are fixedly connected between the tops of the two end plates 11. Obstacle avoidance arc protrusions 58 are fixedly connected at equal intervals at the bottoms of the two obstacle avoidance limit rods 57. The two obstacle avoidance rollers 56 are tumblingly connected to the bottoms of the two obstacle avoidance limit rods 57. Since the bottom of the transparent canopy 103 is supported by the canopy support rod 102, the canopy support rod 102 will obstruct the droplet scraping strip 55. Therefore, the obstacle avoidance arc protrusion 58 on the obstacle avoidance limit rod 57 is set to correspond to the canopy support rod 102 on the lower side of the transparent canopy 103. When the walking block 15 moves back and forth, the obstacle avoidance roller 56 rolls on the lower side of the obstacle avoidance limit rod 57. When the obstacle avoidance roller 56 encounters the obstacle avoidance arc protrusion 58, the square rod 51 moves down relative to the rectangular frame 21, and the spring 53 is compressed. At this time, the droplet scraping strip 55 on the mounting strip 54 moves down with the square rod 51, allowing the droplet scraping strip 55 to move down past the canopy support rod 102. After the obstacle avoidance roller 56 passes the obstacle avoidance arc protrusion 58, the droplet scraping strip 55 also passes the canopy support rod 102, the spring 53 returns to its original length and extends, and the top of the droplet scraping strip 55 contacts the lower side of the transparent canopy 103 again.

[0065] Example 4, please refer to Figures 1 to 10 This embodiment provides a technical solution: an integrated intelligent irrigation system for greenhouses, combining water, fertilizer, gas, and heat. This embodiment is structurally similar to Embodiment 3, with the difference being:

[0066] It also includes a greenhouse ventilation and cooling mechanism 8, which includes a circular channel 81, an inlet fan 82, an exhaust fan 86, and a circular channel sealing assembly. Two circular channels 81 are respectively opened on the top of the two end plates 11. An inlet fan 82 is installed in one of the circular channels 81 and blows air into the inside of the end plate 11. An exhaust fan 86 is installed in the other circular channel 81 and blows air into the outside of the end plate 11. Two circular channel sealing assemblies are respectively installed on the side of the two end plates 11 that are far apart from each other.

[0067] The circular slot enclosure assembly includes linear motor guide rails 83, linear motors 84, and enclosure plates 85. Two vertical linear motor guide rails 83 are fixedly connected to the left and right ends of the two end plates 11 on the side away from each other. The two linear motor guide rails 83 are respectively connected to two linear motors 84. The two corresponding linear motors 84 are fixedly connected to both sides of an enclosure plate 85. The linear motors 84 move up and down along the linear motor guide rails 83, which can drive the enclosure plate 85 to move up and down. When the enclosure plate 85 moves up, it can block the circular slot 81. When the enclosure plate 85 moves down, it can open the circular slot 81.

[0068] When the temperature inside the greenhouse is low or normal, the circular channel sealing component blocks the circular channel 81. When the temperature inside the greenhouse is too high, the circular channel sealing component opens both circular channels 81, and the inlet fan 82 and the exhaust fan 86 work simultaneously. The inlet fan 82 blows cold air into the greenhouse, and the exhaust fan 86 blows hot air out of the greenhouse to lower the temperature inside the greenhouse.

[0069] A temperature and humidity sensor 92 is mounted on the bottom of the end plate 11 via a sensor bracket 91. The temperature and humidity sensor 92 is located inside the greenhouse. The output of the temperature and humidity sensor 92 is electrically connected to the input of an external controller. The external controller controls the operation of the walking motor 14, electric telescopic rod 1 23, electric telescopic rod 2 31, water pump 36, electric telescopic rod 3 45, irrigation liquid pump 48, pitch motor 69, air pump 71, heating wire 74, intake fan 82, and exhaust fan 86. The control method adopts a method commonly used in existing technology. Due to the use of the temperature and humidity sensor 92, the heating wire 74 in the greenhouse ventilation and cooling mechanism 8, the defogging and blowing heating mechanism 7, and the multi-functional atomizing humidification mechanism 3, in conjunction with the external controller, the temperature and humidity inside the greenhouse can be intelligently controlled. The walking motor 14 and the pitch motor 69 are servo motors, and the specific models can be selected according to actual needs.
