Description

Technical Field

[0001] The invention relates to the technical field of greenhouse irrigation equipment, and in particular to a greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system. Background Art

[0002] A greenhouse refers to 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, generation breeding and ornamental plant cultivation.

[0003] Since the greenhouse is a closed space, natural rainwater cannot fall into the greenhouse, so the plants in the greenhouse need to be irrigated. If irrigation pipes are arranged on the top of the greenhouse, the irrigation pipes can only spray water, and liquid fertilizers cannot be sprayed, because liquid fertilizers will fall on the leaves of plants and hurt the plants. When irrigation pipes are arranged on the ground to directly water the roots of plants, the irrigation pipes on the ground will affect the cultivation and weeding of the plants, and a large amount of mist droplets will condense on the inner wall of the greenhouse at low temperatures. These mist droplets affect the light in the greenhouse and the growth of plants. In addition, the internal temperature of the greenhouse is prone to fluctuations depending on the time of day, which is not conducive to the rapid growth of plants. The temperature inside the greenhouse needs to be controlled according to the situation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a greenhouse water-fertilizer-gas-heat integrated intelligent irrigation system. The irrigation pipe is arranged at the top of the greenhouse. The irrigation pipe can be swung and lowered to near the ground as needed. Water and liquid fertilizer can be sprayed in the irrigation pipe. Spraying water can prevent water from knocking off the flowers of the plants and directly water the roots of the plants. When spraying liquid fertilizer, it can prevent the liquid fertilizer from falling on the leaves of the plants and damaging the plants. When irrigation is not needed, it is stored at the top of the greenhouse, which will not affect the cultivation and weeding operations of the plants. It can spray humidification in the greenhouse and control the temperature in the greenhouse, so that the temperature and humidity in the greenhouse can be controlled to promote plant growth. It can handle a large number of droplets condensed on the inner wall of the greenhouse at low temperatures, increase the amount of light in the greenhouse, and help plants receive light and grow quickly and well. The problems in the background technology can be effectively solved.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system, including a roof walking mechanism, the roof walking mechanism includes an end plate, a guide rod, a walking seat block and a longitudinal moving force component, the end plate is provided with two and arranged correspondingly in front and back, two longitudinal guide rods are arranged between the two end plates, two sliding grooves on the walking seat block are longitudinally slidably connected with the two guide rods, the walking seat block is connected to the longitudinal moving force component, and also includes: The irrigation swing control mechanism includes a synchronous swing power assembly, a swing rod and a transverse slide groove. The synchronous swing power assembly is installed in the middle of the walking seat block. The bottom of the synchronous swing power assembly is connected to two swing rods, and each swing rod is provided with a transverse slide groove. The multifunctional atomizing humidifying mechanism comprises an electric telescopic rod 2, an atomizing hard pipe, an atomizing nozzle and an atomizing water supply assembly. One end of the horizontal slide groove near the walking seat block is fixedly connected to the fixed end of the electric telescopic rod 2, the telescopic end of the electric telescopic rod 2 is connected to one end of the atomizing hard pipe, the atomizing hard pipe is slidably connected to the horizontal slide groove, and the other end of the atomizing hard pipe extends to the outside of the end of the horizontal slide groove. Atomizing nozzles are arranged at equal distances at the bottom of the atomizing hard pipe, and the atomizing hard pipe is connected to the atomizing water supply assembly; The water and fertilizer irrigation mechanism is installed at one end of the atomizing hard pipe away from the walking seat block.

[0006] The end plates and the guide rods form a frame, which is installed on the top of the greenhouse, and the sides of the two end plates that are away from each other are respectively located on the front and rear outer sides of the top of the greenhouse. The longitudinal movement power component can drive the walking seat block to move forward and backward along the guide rod, so that the walking seat block can move forward and backward on the top of the greenhouse, so that the multifunctional atomizing humidification mechanism and the water and fertilizer irrigation mechanism can fully humidify and irrigate the greenhouse. The synchronous swing power component is used to drive the two swing arms to approach each other synchronously or move away from each other synchronously, that is, to drive the two swing arms to be in a horizontal state or in a vertical state at the same time. The two swing arms are in a vertical state at the same time. When the two swing arms are in a horizontal state at the same time, the two swing arms are close to each other, and the horizontal sliding groove on the swing arm is used to limit the atomizing hard pipe, so that the atomizing hard pipe can only slide along the direction of the swing arm. The electric telescopic rod 2 can push the atomizing hard pipe to move in the horizontal sliding groove. When the two swing arms are in a horizontal state at the same time, the atomizing nozzle on the atomizing hard pipe is set downward, and the atomizing water supply component supplies water to the atomizing hard pipe. The water in the atomizing hard pipe is atomized by the atomizing nozzle and then sprayed out, which can increase the humidity in the greenhouse. When the two swing arms are in a vertical state 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 the plants to directly irrigate the roots of the plants.

[0007] Furthermore, the synchronous swing power assembly includes a rectangular frame, a guide protrusion, an electric telescopic rod 1, a guide vertical rod, a double-sided rack, a gear seat and a gear. A vertical groove is opened in the middle of the walking seat block, and the top of the walking seat block is fixedly connected to the rectangular frame by bolts. A guide protrusion is provided at the bottom center of the rectangular frame. The guide vertical rod is vertically slidably connected in the guide slide 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 an electric telescopic rod 1. The bottom end of the guide vertical rod is fixedly connected to the top of the double-sided rack, and the double-sided rack passes through the middle of the vertical groove. Two gear seats are fixedly connected to the two sides of the bottom of the walking seat block, and the two gear seats are rotatably connected to two gears. The two gears are respectively meshed with the two sides of the double-sided rack, and the two gears are fixedly connected to one end of the two swing arms. The guide groove in the middle of the guide protrusion limits the guide vertical rod, so that the guide vertical rod and the double-sided rack can only move up and down. When the electric telescopic rod is extended, the double-sided rack is driven to descend through the guide vertical rod, and the meshing action of the double-sided rack and the two gears drives the two swing rods to move away from each other synchronously until the two swing rods are in a horizontal state and stop. When the electric telescopic rod is shortened, the double-sided rack is driven to rise through the guide vertical rod, and the meshing action of the double-sided rack and the two gears drives the two swing rods to move closer to each other synchronously until the two swing rods are in a vertical state and stop.

[0008] Furthermore, the water and fertilizer irrigation mechanism includes a support, a movable shaft, an irrigation hard pipe, an irrigation head, an electric telescopic rod three and an irrigation water supply 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 distances on the irrigation hard pipe. The part of the atomizing hard pipe located outside the transverse slide groove is movably connected to one end of the electric telescopic rod three. The other end of the electric telescopic rod three is movably connected to the irrigation hard pipe. The irrigation hard pipe is connected to the irrigation water supply assembly.

[0009] When the two swing arms are in a vertical state, the electric telescopic rod 3 pushes the irrigation pipe to move relative to the support through the movable axis until the irrigation pipe is perpendicular to the two swing arms and the atomizing pipe. At this time, the irrigation head on the irrigation pipe is set downward. If the height of the irrigation head spraying water or liquid fertilizer is still high, in order to prevent water or liquid fertilizer from falling on the leaves of plants, the electric telescopic rod 2 is extended to push the atomizing pipe downward along the horizontal slide groove on the swing arm to make the irrigation pipe close to the ground. If the irrigation position needs to be changed, the electric telescopic rod 2 is shortened, and the roof travel mechanism moves forward or backward for a distance to allow the horizontal irrigation pipe to pass over a row of watered plants. Then the electric telescopic rod 2 is extended again to allow the irrigation pipe to be close to the ground again. If the electric telescopic rod 2 is shortened to the shortest and the irrigation pipe still cannot be higher than the top of the plant, the synchronous swing power assembly controls the two swing arms to swing and rise to ensure that the irrigation pipe can pass over the top of the plant. If irrigation is no longer needed, the second electric telescopic rod is shortened first to allow the atomizing tube to retract into the horizontal slide groove, and then the third electric telescopic rod is shortened to allow the irrigation tube to be folded close to the swing arm, and then the synchronous swing power assembly controls the two swing arms to move to a horizontal state.

[0010] Furthermore, it also includes a blowing pitch control mechanism, which includes a bent frame, a mounting slot, a pitch axis, a pitch arm and a pitch power assembly. Two bent frames are fixedly connected to the left and right sides of the rectangular frame, and each bent frame is provided with a mounting slot. The middle part of the pitch arm is movably connected to each mounting slot through a longitudinal pitch axis. The pitch power assembly is connected to the end of each pitch arm close to the rectangular frame, and the pitch arm is connected to the defogger blowing and heating mechanism. The pitch power assembly is used to drive the pitch arm to move in the mounting slot through the pitch axis, thereby changing the pitch angle of the airflow blown out by the defogger blowing and heating mechanism.

[0011] Furthermore, the defogger, air blowing and heating mechanism includes an air pump, a soft air pipe, a heating chamber and an airflow guide box. A heating chamber is respectively opened in the two pitch arms. The two heating chambers are respectively connected to one end of the two soft air pipes at one end close to the rectangular frame, and the other ends of the two soft air pipes are connected to the air outlet of the air pump. The air pump is installed on the walking seat block, and the two pitch arms are respectively fixedly connected to two airflow guide boxes at one end away from the rectangular frame. The air pump blows air into the heating chamber through a soft air pipe, and the airflow in the heating chamber is blown out through an airflow guide box. When a large number of droplets appear on the lower side of the transparent roof of the greenhouse mechanism, affecting the light exposure of the plants, the airflow guide box blows airflow towards the droplets, causing the droplets to slide along the lower side of the transparent roof. The pitch power assembly continuously changes the pitch correction of the pitch arm and the airflow guide box, thereby performing a comprehensive droplet blowing operation on the lower side of the transparent roof. This type of droplet treatment is suitable for the treatment of droplets on the lower side of different transparent roofs, and is especially suitable for situations where the structure of the lower side bracket of the transparent roof is complex. The droplets are blown off by airflow without being interfered with by the lower side bracket of the transparent roof.

[0012] Furthermore, the demisting air blowing and heating mechanism also includes an electric heating wire, and each heating chamber is provided with a spiral electric heating wire. The electric heating wire heats the airflow passing through the heating chamber, so that the airflow guide box can blow out hot air, which can heat the temperature in the greenhouse and adjust the low temperature in the greenhouse. At the same time, the hot air is also conducive to evaporating the fog droplets on the lower side of the transparent roof.

[0013] Furthermore, the defogger, blow and heat raising mechanism also includes an opening and closing shaft, an opening and closing plate and a torsion spring. One side of the opening and closing plate is movably connected to each airflow guide box through the opening and closing shaft. The opening and closing plate is arranged corresponding to the end of the heating chamber. The end of the opening and closing shaft is sleeved with a torsion spring. 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, and the heating wire needs to be replaced frequently. Therefore, a torsion spring is arranged. The torsion force of the torsion spring allows 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 soft air pipe, the airflow blowing force overcomes the torsion force of the torsion spring, allowing the opening and closing plate to open the end of the heating chamber, allowing the airflow guide box to blow normally. When the air pump stops working, the torsion spring drives the opening and closing plate to re-close the end of the heating chamber to protect the heating wire.

[0014] Furthermore, it also includes a droplet scraping mechanism, which includes a square rod, a spring, a mounting bar and a droplet scraping rubber strip. Two square rods are vertically slidably connected in two square holes on both sides of the top of the rectangular frame, and two mounting bars are fixedly connected on the sides of the tops of the two square rods away from each other. A droplet scraping rubber strip is detachably installed on each mounting bar. The rod section of the square rod located between the mounting bar and the rectangular frame is sleeved with a spring, and the upper and lower ends of the spring are respectively connected to the mounting bar and the rectangular frame. When the rectangular frame moves forward and backward with the walking seat block, the droplet scraping rubber strip on the mounting bar can scrape the droplets on the lower side of the transparent shed roof to prevent the droplets from affecting the light in the greenhouse. The spring pushes the square rod to move upward, so that the top of the droplet scraping rubber strip is close to the lower side of the transparent shed roof. Since it directly contacts the transparent shed roof, it is suitable for the situation where the bracket structure on the lower side of the transparent shed roof is simple. This scraping method has high efficiency in processing droplets, and the droplet scraping rubber strip can be deformed and replaced.

[0015] Furthermore, the droplet scraping mechanism also includes a wheel seat, an obstacle avoiding roller, an obstacle avoiding limiting rod, and an obstacle avoiding arc protrusion. A wheel seat is installed on the top of each square rod, and an obstacle avoiding roller is rotatably installed on each wheel seat. Two longitudinal obstacle avoiding limiting rods are fixedly connected between the tops of the two end plates, and obstacle avoiding arc protrusions are fixedly connected to the bottoms of the two obstacle avoiding limiting rods at equal distances. The two obstacle avoiding rollers are rollingly connected to the bottoms of the two obstacle avoiding limiting rods. Since the bottom of the transparent shed roof is supported by the shed support rods, the shed support rods will hinder the droplet scraping strips, so the obstacle avoiding arc protrusions on the obstacle avoiding limit rods are arranged corresponding to the shed support rods on the lower side of the transparent shed roof. When the walking seat block moves forward and backward, the obstacle avoiding rollers roll on the lower side of the obstacle avoiding limit rods. When the obstacle avoiding rollers encounter the obstacle avoiding arc protrusions, the square rods move downward relative to the rectangular frame, and the springs are compressed. At this time, the droplet scraping strips on the mounting strips move downward with the square rods, allowing the droplet scraping strips to move downward and pass over the shed support rods. When the obstacle avoiding rollers pass over the obstacle avoiding arc protrusions, the droplet scraping strips also pass over the shed support rods, the springs reset and extend, and the top of the droplet scraping strips contacts the lower side of the transparent shed roof again.

[0016] Furthermore, it also includes a greenhouse ventilation and cooling mechanism, which includes a round groove, an inlet fan, an exhaust fan and a round groove closing component. Two round grooves are respectively opened on the top of the two end plates, one of which is equipped with an inlet fan, and the inlet fan blows air to the inside of the end plate, and the other is equipped with an exhaust fan, and the exhaust fan blows air to the outside of the end plate. Two round groove closing components are respectively installed on the sides of the two end plates away from each other. When the temperature in the greenhouse is too high, the round groove closing component opens the two round grooves, and the inlet fan and the exhaust fan work at the same time. The inlet fan blows cold air into the greenhouse, and the exhaust fan blows hot air out of the greenhouse to reduce the temperature in the greenhouse.

[0017] Compared with the existing technology, the beneficial effects of this greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system are: 1. Arrange the irrigation pipes at the top of the greenhouse. The irrigation pipes can be swung down to the ground as needed. Water and liquid fertilizers can be sprayed in the irrigation pipes. Spraying water can prevent water from knocking down the flowers of the plants and directly water the roots of the plants. When spraying liquid fertilizers, it can prevent liquid fertilizers from falling on the leaves of the plants and harming the plants. When irrigation is not needed, they can be stored at the top of the greenhouse, which will not affect the cultivation and weeding operations of the plants. 2. The atomizing water supply component supplies water to the atomizing hard pipe. The water in the atomizing hard pipe is atomized and sprayed out through the atomizing nozzle, which can increase the humidity in the greenhouse and spray humidification in the greenhouse; 3. The electric 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 in the greenhouse and adjust the low temperature in the greenhouse. At the same time, the hot air is also conducive to evaporating the droplets on the lower side of the transparent roof. When the temperature in the greenhouse is too high, the round groove closing component opens the two round grooves, and the inlet fan and the exhaust fan work at the same time. The inlet fan blows cold air into the greenhouse, and the exhaust fan blows hot air out of the greenhouse, lowering the temperature in the greenhouse, thereby controlling the temperature in the greenhouse; 4. When the rectangular frame moves back and forth with the walking seat block, the mist droplet scraping strip on the mounting strip can scrape the mist droplets on the lower side of the transparent roof to prevent the mist droplets from affecting the light in the greenhouse, increase the amount of light in the greenhouse, and help the plants receive light and grow quickly and well.

The two atomizing hard pipes 32 are respectively connected to one end of an atomizing hose 35 through two atomizing branch pipes 34, and the other end of the atomizing hose 35 is connected to the water outlet of the water pump 36. The water pump 36 is installed at the bottom of the front end plate 11. The water 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 pipe 34 and the atomizing hose 35.

[0023] The water and fertilizer irrigation mechanism 4 is installed at one end of the atomizing hard pipe 32 away from the traveling seat block 15 .

[0024] 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 three 45 and an irrigation water supply 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 on the irrigation hard pipe 43 at equal distances. The part of the atomizing hard pipe 32 located outside the transverse slide groove 29 is movably connected to one end of the electric telescopic rod three 45. The other end of the electric telescopic rod three 45 is movably connected to the irrigation hard pipe 43, and the irrigation hard pipe 43 is connected to the irrigation water supply assembly.

[0025] The irrigation water supply assembly includes an irrigation branch pipe 46, an irrigation hose 47, and an irrigation liquid pump 48. The two irrigation hard pipes 43 are respectively connected to one end of an irrigation hose 47 through 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 respectively connected to the water source and the liquid fertilizer tank through two valves. The irrigation liquid pump 48 can be controlled to connect the water source and the liquid fertilizer tank through the two valves. The irrigation liquid pump 48 pumps water or liquid fertilizer into the two irrigation hard pipes 43 through the irrigation branch pipe 46 and the irrigation hose 47.

[0026] Since the irrigation hose 47 and the mist hose 35 need to move with the walking seat block 15, the irrigation hose 47 and the mist hose 35 are very long, so a hanging line column 93 and a hanging line ring 94 are provided to keep the irrigation hose 47 and the mist hose 35 regular. A longitudinal hanging line column 93 is provided between the two end plates 11, and the hanging line column 93 is slidably connected to the walking seat block 15. A plurality of hanging line rings 94 are equidistantly provided on the irrigation hose 47 and the mist hose 35, and each hanging line ring 94 is slidably connected to a corresponding position on the hanging line column 93. With the help of the hanging line column 93 and the hanging line ring 94, the irrigation hose 47 and the mist hose 35 can remain regular when bent or straightened. Specifically, no less than four hanging line rings 94 are provided on each of the irrigation hose 47 and the mist hose 35.

[0027] When the two swing arms 28 are in a vertical state, the electric telescopic rod 3 45 pushes the irrigation tube 43 to move relative to the support 41 through the movable shaft 42 until the irrigation tube 43 is perpendicular to the two swing arms 28 and the atomizing tube 32. At this time, the irrigation head 44 on the irrigation tube 43 is set downward. If the height of the irrigation head 44 spraying water or liquid fertilizer is still high, in order to prevent the water or liquid fertilizer from falling on the leaves of the plants, the electric telescopic rod 2 31 is extended to push the atomizing tube 32 to move downward along the horizontal slide groove 29 on the swing arm 28, so that the irrigation tube 43 is close to the ground. 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 for a distance to allow the horizontal irrigation pipe 43 to pass over a row of watered plants, and then the electric telescopic rod 2 31 is extended again to allow the irrigation pipe 43 to be close to the ground again. If the electric telescopic rod 2 31 is shortened to the shortest and the irrigation pipe 43 still cannot be higher than the top of the plant, the synchronous swing power assembly controls the two swing arms 28 to swing and rise to ensure that the irrigation pipe 43 can pass over the top of the plant; If irrigation is no longer needed, the electric telescopic rod 2 31 is shortened first to allow the atomizing tube 32 to retract into the horizontal slide groove 29, and then the electric telescopic rod 3 45 is shortened to allow the irrigation tube 43 to fold up close to the swing rod 28, and then the synchronous swing power assembly controls the two swing rods 28 to move to a horizontal state.

[0028] The top of the greenhouse adopts a greenhouse shed mechanism 10, which includes a longitudinal beam 101, a shed support rod 102, and a transparent shed roof 103. Fig.10 Shed support rods 102 are equidistantly arranged on the left and right sides of the longitudinal beam 101. The longitudinal beam 101 and the shelf support rods 102 constitute a support structure, and a transparent roof 103 is arranged on the upper side of the support structure.

[0029] When in use, the end plate 11 and the guide rod 12 form a frame, and the frame is installed on the longitudinal beam 101 at the top of the greenhouse, and the sides of the two end plates 11 that are away from each other are respectively located on the front and rear outer sides of the top of the greenhouse. The longitudinal movement power component can drive the walking seat block 15 to move forward and backward along the guide rod 12, so that the walking seat block 15 can move forward and backward at the top of the greenhouse, so that the multifunctional atomizing humidification mechanism 3 and the water and fertilizer irrigation mechanism 4 can fully humidify and irrigate the greenhouse. The synchronous swing power component is used to drive the two swing arms 28 to approach each other or move away from each other synchronously, that is, to drive the two swing arms 28 to be in a horizontal state or in a vertical state at the same time, and the two swing arms 28 are in a vertical state at the same time. When the two swing arms 28 are in a horizontal state at the same time, the atomizing nozzle 33 on the atomizing tube 32 is arranged downward, and the atomizing water supply component supplies water to the atomizing tube 32. The water in the atomizing tube 32 is atomized and sprayed out through the atomizing nozzle 33, which can increase the humidity in the greenhouse. When the two swing arms 28 are in a vertical state at the same time, the water and fertilizer irrigation mechanism 4 can be close to the ground to spray water or liquid fertilizer on the roots of the plants to directly irrigate the roots of the plants.

[0030] For example 2, please refer to Figures 1 to 10This embodiment provides a technical solution: a greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system. The structure of this embodiment is roughly the same as that of the first embodiment, except that: It also includes an air blowing pitch control mechanism 6, which includes a bent frame 61, a mounting slot 62, a pitch axis 63, a pitch arm 64 and a pitch power assembly. Two bent frames 61 are fixedly connected to the left and right sides of the rectangular frame 21, and each bent frame 61 is provided with a mounting slot 62. Each mounting slot 62 is movably connected to the middle part of the pitch arm 64 through a longitudinal pitch axis 63. One end of each pitch arm 64 close to the rectangular frame 21 is connected to a pitch power assembly, and the pitch arm 64 is connected to the defogger blowing and heating mechanism 7.

[0031] The pitch power assembly includes a semicircular plate 65, an arc slide 66, a fan-shaped slider 67, a bent arm 68, and a pitch motor 69. The end of each pitch arm 64 close to the rectangular frame 21 is fixedly connected to the semicircular plate 65, and the arc slide 66 is provided on the arc surface of the semicircular plate 65. The pitch motor 69 is installed on the bent frame 61 through the motor seat. The output shaft of the pitch motor 69 is fixedly connected to one end of the bent arm 68, and the other end of the bent arm 68 is movably connected to the fan-shaped slider 67 through the bent arm shaft. The fan-shaped slider 67 is slidably connected to the circular arc slide groove 66, and the pitch motor 69 drives the bent arm 68 to rotate. The bent arm 68 drives the fan-shaped slider 67 to rotate through the bent arm shaft. The sliding of the fan-shaped slider 67 in the circular arc slide groove 66 can offset the horizontal movement of the fan-shaped slider 67. The vertical movement of the fan-shaped slider 67 can drive the pitch arm 64 to move relative to the pitch axis 63 in the mounting groove 62 through the semicircular plate 65, thereby allowing the end of the pitch arm 64 to pitch.

[0032] The pitch power assembly is used to drive the pitch arm 64 to move in the installation slot 62 via the pitch axis 63 , thereby changing the pitch angle of the airflow blown out by the defogger, air blowing and heating mechanism 7 .

[0033] The defogger, blow and warming mechanism 7 comprises an air pump 71, a soft air pipe 72, a heating chamber 73 and an airflow guide box 75. A heating chamber 73 is respectively provided in the two pitch arms 64. One end of the two heating chambers 73 close to the rectangular frame 21 is respectively connected to one end of the two soft air pipes 72. The other ends of the two soft air pipes 72 are connected to the air outlet of the air pump 71. The air pump 71 is installed on the walking seat block 15. The two ends of the two pitch arms 64 away from the rectangular frame 21 are respectively fixedly connected to two airflow guide boxes 75. The air pump 71 blows air into the heating chamber 73 through the soft air tube 72, and the airflow in the heating chamber 73 is blown out through the airflow guide box 75. When a large number of droplets appear on the lower side of the transparent roof 103 of the greenhouse shed mechanism 10 and affect the plants' reception of light, the airflow guide box 75 blows airflow towards the droplets, causing the droplets to slide along the lower side of the transparent roof 103. The pitch power assembly continuously changes the pitch alignment of the pitch arm 64 and the airflow guide box 75, thereby performing a comprehensive droplet blowing operation on the lower side of the transparent roof 103. This treatment of droplets is suitable for the treatment of droplets on the lower side of different transparent roofs 103, and is especially suitable for situations where the support structure on the lower side of the transparent roof 103 is complex. The droplets are blown off by airflow without being interfered with by the support on the lower side of the transparent roof 103.

[0034] The defogger blowing and heating mechanism 7 also includes a heating wire 74, and a spiral heating wire 74 is respectively arranged in each heating chamber 73. The heating wire 74 heats the airflow passing through the heating chamber 73, and allows the airflow guide box 75 to blow out hot air, which can heat the temperature in the greenhouse and adjust the low temperature in the greenhouse. At the same time, the hot air is also conducive to evaporating the fog droplets on the lower side of the transparent roof 103.

[0035] The defogger, blow and heat raising mechanism 7 also includes an opening and closing shaft 76, an opening and closing plate 77 and a torsion spring 78. One side of the opening and closing plate 77 is movably connected to each airflow guide box 75 through the opening and closing shaft 76. The opening and closing plate 77 is arranged corresponding to the end of the heating chamber 73. The end of the opening and closing shaft 76 is sleeved with a torsion spring 78. The two ends of the torsion spring 78 are respectively connected to the opening and closing plate 77 and the airflow guide box 75. When the humidity in the greenhouse is high, it will cause rapid corrosion of the heating wire 74, and the heating wire 74 needs to be replaced frequently. Therefore, a torsion spring 78 is provided. The torque of the torsion spring 78 allows 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 soft air pipe 72, the air flow blowing force overcomes the torque of the torsion spring 78, allowing the opening and closing plate 77 to open the end of the heating chamber 73, allowing the air flow guide box 75 to blow normally. When the air pump 71 stops working, the torsion spring 78 drives the opening and closing plate 77 to re-close the end of the heating chamber 73 to protect the heating wire 74.

[0036] For example 3, please refer to Figures 1 to 10 This embodiment provides a technical solution: a greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system. The structure of this embodiment is roughly the same as that of the second embodiment, except that: It also includes a droplet scraping mechanism 5, which includes a square rod 51, a spring 53, a mounting bar 54 and a droplet scraping rubber strip 55. Two square rods 51 are vertically slidably connected in two square holes on both sides of the top of the rectangular frame 21, and two mounting bars 54 are fixedly connected on the sides of the tops of the two square rods 51 away from each other. A droplet scraping rubber strip 55 is detachably installed on each mounting bar 54. The rod section of the square rod 51 located between the mounting bar 54 and the rectangular frame 21 is sleeved with a spring 53, and the upper and lower ends of the spring 53 are respectively connected to the mounting bar 54 and the rectangular frame 21. When the rectangular frame 21 moves back and forth with the walking seat block 15, the droplet scraping strip 55 on the mounting strip 54 can scrape the droplets on the lower side of the transparent roof 103 to prevent the droplets from affecting the lighting in the greenhouse. The spring 53 pushes the square rod 51 upward to allow the top of the droplet scraping strip 55 to be in close contact with the lower side of the transparent roof 103. Since it directly contacts the transparent roof 103, it is suitable for the situation where the bracket structure on the lower side of the transparent roof 103 is simple. This scraping method has high efficiency in processing droplets, and the droplet scraping strip 55 can be deformed and replaced.

[0037] The droplet scraping mechanism 5 also includes a wheel seat 52, an obstacle avoiding roller 56, an obstacle avoiding limiting rod 57, and an obstacle avoiding arc protrusion 58. A wheel seat 52 is installed on the top of each square rod 51, and an obstacle avoiding roller 56 is rotatably installed on each wheel seat 52. Two longitudinal obstacle avoiding limiting rods 57 are fixedly connected between the tops of the two end plates 11, and obstacle avoiding arc protrusions 58 are fixedly connected to the bottoms of the two obstacle avoiding limiting rods 57 at equal distances. The two obstacle avoiding rollers 56 are rollingly connected to the bottoms of the two obstacle avoiding limiting rods 57. Since the bottom of the transparent roof 103 is supported by the roof support rod 102, the roof support rod 102 will hinder the droplet scraping strip 55, so the obstacle avoiding arc protrusion 58 on the obstacle avoiding limit rod 57 is arranged corresponding to the roof support rod 102 on the lower side of the transparent roof 103. When the walking seat block 15 moves forward and backward, the obstacle avoiding roller 56 rolls on the lower side of the obstacle avoiding limit rod 57. When the obstacle avoiding roller 56 encounters the obstacle avoiding arc protrusion 58, the square rod 51 moves downward relative to the rectangular frame 21, and the spring 53 is compressed. At this time, the droplet scraping strip 55 on the mounting bar 54 moves downward with the square rod 51, allowing the droplet scraping strip 55 to move downward and pass over the roof support rod 102. When the obstacle avoiding roller 56 passes over the obstacle avoiding arc protrusion 58, the droplet scraping strip 55 also passes over the roof support rod 102, the spring 53 resets and stretches, and the top of the droplet scraping strip 55 contacts the lower side of the transparent roof 103 again.

[0038] Example 4, please refer to Figures 1 to 10 This embodiment provides a technical solution: a greenhouse water, fertilizer, gas and heat integrated intelligent irrigation system. The structure of this embodiment is roughly the same as that of the third embodiment, except that: It also includes a greenhouse ventilation and cooling mechanism 8, which includes a circular groove 81, an inlet fan 82, an exhaust fan 86 and a circular groove closing component. Two circular grooves 81 are respectively provided on the top of the two end plates 11. An inlet fan 82 is installed in one of the circular grooves 81, and the inlet fan 82 blows air toward the inside of the end plate 11. An exhaust fan 86 is installed in the other circular groove 81, and the exhaust fan 86 blows air toward the outside of the end plate 11. Two circular groove closing components are respectively installed on the side of the two end plates 11 away from each other.

[0039] The circular groove closing component includes a linear motor guide 83, a linear motor 84, and a closing plate 85. Two vertical linear motor guides 83 are fixedly connected to the left and right ends of the side of the two end plates 11 that are away from each other. The two linear motor guides 83 are respectively connected to the two linear motors 84. The two corresponding linear motors 84 are fixedly connected to the two sides of a closing plate 85. The linear motor 84 moves up and down along the linear motor guide 83, which can drive the closing plate 85 to move up and down. When the closing plate 85 moves up, it can block the circular groove 81. When the closing plate 85 moves down, the circular groove 81 can be opened.

[0040] When the temperature in the greenhouse is low or normal, the round groove closing assembly blocks the round groove 81. When the temperature in the greenhouse is too high, the round groove closing assembly opens the two round grooves 81, and the inlet fan 82 and the exhaust fan 86 work at the same time. The inlet fan 82 blows cold air into the greenhouse, and the exhaust fan 86 blows hot air out of the greenhouse to reduce the temperature in the greenhouse.

[0041] A temperature and humidity sensor 92 is installed at the bottom of the end plate 11 through a sensor bracket 91. The temperature and humidity sensor 92 is located in the greenhouse. The output end of the temperature and humidity sensor 92 is electrically connected to the input end of the external controller. The external controller controls the walking motor 14, the electric telescopic rod 1 23, the electric telescopic rod 2 31, the water pump 36, the electric telescopic rod 3 45, the irrigation liquid pump 48, the pitch motor 69, the air pump 71, the heating wire 74, the air intake fan 82, and the exhaust fan 86. The control method adopts the method commonly used in the prior art. Since the temperature and humidity sensor 92, the greenhouse ventilation and cooling mechanism 8, the heating wire 74 in the defogger and air blowing heating mechanism 7, and the multifunctional atomizing and humidifying mechanism 3 are used in conjunction with the external controller, the temperature and humidity in the greenhouse can be intelligently controlled. The walking motor 14 and the pitch motor 69 adopt servo motors, and the specific models can be selected according to actual needs.
