Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse planting, and particularly relates to an automatic fertilizing device for greenhouse planting and a working method thereof. Background Art

[0002] The greenhouse fertilizing device is an important equipment for precise and efficient fertilization in modern agriculture, especially suitable for closed or semi-closed planting environments such as greenhouses and sheds. The fertilizer-water mixture is atomized and sprayed through a nozzle, covering the leaves and roots of crops.

[0003] Traditional fixed sprinkler irrigation or rail fertilizing machines cannot dynamically adjust the nozzle spacing, and the nozzles are generally evenly distributed. During the fertilization process, there are different varieties of crops planted at different times in the greenhouse. The planting distribution of different crops is different, and the spraying density of the same crop at different growth stages is different. Fertilization in a fixed mode is likely to cause uneven growth of crops, and some fertilizer-water is sprayed onto the reserved space set for convenient labor, resulting in waste of resources. During the fertilization process, the fertilizer-water is likely to block the nozzles. After the traditional nozzles are blocked, they need to be manually disassembled and cleaned, affecting the continuity of operations. Summary of the Invention

[0004] The problem solved by the present invention is to provide an automatic fertilizing device for greenhouse planting and a working method thereof, which solve the technical problems that traditional fixed sprinkler irrigation or rail fertilizing machines cannot dynamically adjust the nozzle spacing, and the nozzles are generally evenly distributed. During the fertilization process, there are different varieties of crops planted at different times in the greenhouse. The planting distribution of different crops is different, and the spraying density of the same crop at different growth stages is different. Fertilization in a fixed mode is likely to cause uneven growth of crops, and some fertilizer-water is sprayed onto the reserved space set for convenient labor, resulting in waste of resources. During the fertilization process, the fertilizer-water is likely to block the nozzles. After the traditional nozzles are blocked, they need to be manually disassembled and cleaned, affecting the continuity of operations.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic fertilizing device for greenhouse planting includes a support base, a pulley seat, a support arm, a T-shaped rail, a translation seat, and a spraying seat. A pulley seat that slides along a slide rail is installed on the top of the support base, and the slide rail is located on the top of the greenhouse. Support arms are installed on both sides of the bottom of the support base. The support arm and the support base are fixedly connected and reinforced by a plurality of connecting steel ropes. A T-shaped rail is arranged on the support arm. A plurality of translation seats are slidably installed on the T-shaped rail. A spraying seat is installed on the bottom side of the translation seat. A water pipe seat is installed on the support base. A first connecting hose is connected between adjacent translation seats, between the translation seat and the water pipe seat. The water pipe seat is connected to a liquid pump through a first main pipe. A clogging clearing mechanism is installed on the translation seat.

[0007] Preferably, an inner cavity is formed in the translation seat, water channels are arranged on both sides of the inner cavity, and the water channels are communicated with the first connecting hoses.

[0008] Preferably, the blockage clearing mechanism includes a seat sleeve installed on the top of the translation seat. A sealing seat is installed in the seat sleeve and the inner cavity. The inner diameter of the seat sleeve is the same as the diameter of the inner cavity. A sealing ring is arranged on the outer side of the sealing seat, and a spring is installed at the bottom of the sealing seat and located inside the inner cavity.

[0009] Preferably, a first air hole is formed in the seat sleeve, and the first air hole is connected to an air duct through a nozzle. The air ducts are all connected to the second connecting hoses. An air groove is formed at the bottom of the sealing seat, and a second air hole communicated with the air groove is formed in the side wall of the sealing seat.

[0010] Preferably, an air pipe seat is installed on the support seat. The second connecting hose is connected to the air pipe seat, and the air pipe seat is connected to an air pump through a second main pipe.

[0011] Preferably, a plurality of track wheels adapted to the T-shaped rails are installed on the translation seat. A first motor is installed in the translation seat, and the output end of the first motor is connected to one of the track wheels.

[0012] Preferably, a second motor is installed at the end of the support arm. A sliding groove is formed in the support arm, and a threaded rod is installed at the output end of the second motor and located in the sliding groove.

[0013] Preferably, the threaded rod is in threaded connection with a sliding seat, and an installation seat is installed on the sliding seat. An electric push rod is installed on the installation seat, and a pressing plate is installed at the telescopic end of the electric push rod and penetrates through the installation seat.

[0014] A working method of an automatic fertilizing device for greenhouse planting, the specific operation steps of this working method are as follows:

[0015] Step 1: Drive the track wheels to rotate through the operation of the first motor, and then drive the translation seat to move on the support arm. According to the spacing and distribution of the crops in the greenhouse, adjust the spacing of the translation seat to realize the adjustment of the spacing of the spraying seat. During the adjustment process, ensure the mutual connection between the translation seats through the first connecting hoses.

[0016] Step 2: The liquid pump works to transport the water fertilizer through the first main pipe and the water pipe seat to the first connecting hose, and then sequentially transport it to the inner cavity of the translation seat through the first connecting hose, and spray it out through the spraying seat. And move along the greenhouse slide rail through the pulley seat to realize the overall movement of the device.

[0017] Step 3: The second motor works to drive the rotation of the threaded rod, thereby driving the sliding seat connected by threads to move along the support arm. After the spacing of the translation seats is adjusted initially, when the spacing of the translation seats is too large, the redundant translation seats at the end of the support arm are in an idle state at this time. At this time, the sliding seat moves to the first idle translation seat, and the electric push rod drives the pressure plate to move downward to contact the sealing seat. At this time, the sealing seat moves downward in the seat sleeve and the inner cavity until the water channel is blocked, completing the sealing of the spray seat and the water channel. And when the spray seat is blocked, at this time, the sealing seat moves downward until the second air hole corresponds to the first air hole, and at this time, the second connecting hose is communicated with the inner cavity. The air pump is communicated with the corresponding inner cavity through the second main pipe, the air pipe seat and the second connecting hose. The air pump works to generate pulsed negative pressure in the inner cavity, and then sucks the impurities blocking the spray seat into the inner cavity, enters the air pump through the second connecting hose, the air pipe seat and the second main pipe, and is filtered and discharged through the filter provided on the air pump. When the pressure plate moves upward, the compressed spring drives the sealing seat to move upward to restore its original state, and at this time, the water channel is communicated with the inner cavity again.

[0018] The beneficial effects of the present invention are as follows: The T-shaped rail and translation seat design are adopted. The track wheels are driven by the first motor to realize the flexible adjustment of the spacing of the spray seats, adapting to different crop row spacings and different crops. The double-movement design of the support arm and the pulley seat can move horizontally along the sliding rail on the top of the greenhouse. At the same time, the spray seats on the support arm can be longitudinally positioned to form a three-dimensional precise fertilization network.

[0019] The electric push rod controls the pressure plate to press down the sealing seat, realizing the blocking of the water channel and the connection of the air channel, automatically starting the clogging cleaning process without stopping for intervention. The negative pressure is generated by the air pump to suck the blockage from the spray seat into the inner cavity and discharged through the air duct, automatically completing the blockage cleaning, greatly improving the clogging cleaning efficiency.

[0020] The threaded rod rotates, thereby driving the sliding seat connected by threads to move along the support arm to the idle translation seat. The pressure plate presses down to close the water channel, cutting off the water and fertilizer supply of the spray seat, only activating the spray seats that need to operate, and reducing the pumping energy consumption.

[0021] Through the four core innovations of dynamic adjustment, self-cleaning, energy-saving zoning, and intelligent control, the pain points of the traditional greenhouse fertilization device such as uneven coverage, frequent blockages, high energy consumption, and dependence on manual labor are solved.

[0030] See Figures 1 to 4, An automatic fertilization device for greenhouse cultivation, comprising a support base 1, a pulley base 2, a support arm 4, a T-shaped rail 5, a translation base 6 and a spraying base 7. A pulley base 2 that slides along a slide rail is installed on the top of the support base 1, and the slide rail is located at the top of the greenhouse. Support arms 4 are installed on both sides of the bottom of the support base 1. The support arms 4 and the support base 1 are firmly connected by a number of connecting steel ropes 3. A T-shaped rail 5 is provided on the support arm 4. A number of translation bases 6 are slidably installed on the T-shaped rail 5. A number of track wheels 24 adapted to the T-shaped rail 5 are installed on the translation base 6. A first motor 25 is installed inside the translation base 6, and the output end of the first motor 25 is connected to one of the track wheels 24. By the operation of the first motor 25, the track wheel 24 is driven to rotate, thereby driving the translation base 6 to move on the support arm 4. According to the spacing and distribution of the crops in the greenhouse, the spacing of the translation bases 6 is adjusted to achieve the adjustment of the spacing of the spraying bases 7. During the adjustment process, the mutual connection between the translation bases 6 is ensured by the first connecting hose 9. A spraying base 7 is installed on the bottom side of the translation base 6. A water pipe base 8 is installed on the support base 1. The adjacent translation bases 6, and between the translation base 6 and the water pipe base 8 are all connected by the first connecting hose 9. The water pipe base 8 is connected to a liquid pump through a first main pipe 22. An inner cavity 10 is provided inside the translation base 6. Water channels 11 are provided on both sides of the inner cavity 10, and the water channels 11 are communicated with the first connecting hose 9. The liquid pump operates to transport the water and fertilizer through the first main pipe 22 and the water pipe base 8 to the first connecting hose 9, and then sequentially transports it to the inner cavity 10 of the translation base 6 and sprays it out through the spraying base 7. And it moves along the greenhouse slide rail through the pulley base 2 to achieve the overall movement of the device. A clogging clearing mechanism is installed on the translation base 6.

[0031] The clog clearing mechanism includes a seat sleeve 12 installed on the top of the translation seat 6. A sealing seat 13 is installed inside the seat sleeve 12 and the inner cavity 10. The inner diameter of the seat sleeve 12 is the same as the diameter of the inner cavity 10. A sealing ring is provided on the outer side of the sealing seat 13. A spring 20 is installed at the bottom of the sealing seat 13 and inside the inner cavity 10. A first air hole 14 is opened on the seat sleeve 12, and the first air hole 14 is connected to the air duct 16 through a nozzle 15. The air ducts 16 are all connected to the second connecting hose 17. An air groove 18 is opened at the bottom of the sealing seat 13, and a second air hole 19 communicating with the air groove 18 is opened on the side wall of the sealing seat 13. An air pipe seat 21 is installed on the support seat 1. The second connecting hose 17 is connected to the air pipe seat 21. The air pipe seat 21 is connected to an air pump through a second main pipe 23. A second motor 26 is installed at the end of the support arm 4. A sliding groove 27 is opened on the support arm 4. A threaded rod 28 is installed at the output end of the second motor 26 and inside the sliding groove 27. The threaded rod 28 is threadedly connected to a sliding seat 29, and an installation seat 30 is installed on the sliding seat 29. An electric push rod 31 is installed on the installation seat 30, and a pressing plate 32 is installed through the telescopic end of the electric push rod 31 and penetrates the installation seat 30. By the operation of the second motor 26, the threaded rod 28 is driven to rotate, thereby driving the threadedly connected sliding seat 29 to move along the support arm 4. After the spacing of the translation seat 6 is adjusted initially, when the spacing of the translation seat 6 is too large, at this time, the redundant translation seat 6 at the end of the support arm 4 is in an idle state. At this time, the sliding seat 29 moves to the first idle translation seat 6. The electric push rod 31 drives the pressing plate 32 to move downwards to contact the sealing seat 13. At this time, the sealing seat 13 moves downwards in the seat sleeve 12 and the inner cavity 10 until the water channel 11 is blocked, completing the sealing of the spraying seat 7 and the water channel 11. And when the spraying seat 7 is blocked, at this time, the sealing seat 13 moves downwards until the second air hole 19 corresponds to the first air hole 14. At this time, the second connecting hose 17 is communicated with the inner cavity 10. The air pump is communicated with the corresponding inner cavity 10 through the second main pipe 23, the air pipe seat 21 and the second connecting hose 17. The air pump operates to generate a pulsed negative pressure in the inner cavity 10, thereby sucking the impurities blocking the spraying seat 7 into the inner cavity 10, passing through the second connecting hose 17, the air pipe seat 21 and the second main pipe 23 and entering the air pump, and being filtered and discharged through the filter provided on the air pump. When the pressing plate 32 moves upwards, at this time, the compressed spring 20 drives the sealing seat 13 to move upwards and return to its original state. At this time, the water channel 11 is communicated with the inner cavity 10 again.

[0032] The T-shaped rail 5 and the translation seat 6 are designed. By driving the track wheel 24 with the first motor 25, the flexible adjustment of the spacing of the spraying seat 7 is realized, adapting to different crop row spacings and different crops. The double-movement design of the support arm 4 and the pulley seat 2 can move horizontally along the sliding rail on the top of the greenhouse. At the same time, the spraying seat 7 on the support arm 4 can be longitudinally positioned to form a three-dimensional precise fertilization network;

[0033] The electric push rod 31 controls the pressing plate 32 to press down the sealing seat 13, realizing the blocking of the water channel 11 and the connection of the air channel, automatically starting the blockage clearing process without shutdown intervention. By generating negative pressure through an air pump, the blockage is sucked from the spray seat 7 into the inner cavity 10 and discharged through the air duct 16, automatically completing the blockage clearing, greatly improving the blockage clearing efficiency;

[0034] The threaded rod 28 rotates, and then drives the sliding seat 29 connected by threads to move along the support arm 4 to the idle translation seat 6. The pressing plate 32 presses down to close the water channel 11, cutting off the water and fertilizer supply of this spray seat 7, only activating the spray seats 7 that need to operate, and reducing the pumping energy consumption;

[0035] Through the four core innovations of dynamic adjustment, self-cleaning, energy-saving zoning, and intelligent control, the pain points of traditional greenhouse fertilization devices such as uneven coverage, frequent blockages, high energy consumption, and dependence on manual labor are solved.

[0036] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
