Description

Technical Field

[0001] The invention relates to the field of garden seedling cultivation equipment, in particular to a cultivation device for a garden greening nursery and a use method thereof. Background Art

[0002] With the acceleration of urbanization, people's requirements for urban environmental quality are increasing day by day. As an important means to improve the urban ecological environment and landscape quality, the importance of gardening and greening is becoming more and more prominent. As the basic place for cultivating various seedlings, gardening and greening nurseries undertake the key task of providing high-quality seedling resources for urban greening, garden landscape construction, etc. Therefore, how to cultivate seedlings efficiently and scientifically to ensure their healthy growth and meet diverse market needs has become an important issue that needs to be urgently solved in the field of gardening and greening nurseries.

[0003] Traditional nursery irrigation mostly uses flood irrigation or simple sprinkler spraying. Flood irrigation not only wastes water resources seriously, but also easily causes soil compaction, affecting the growth and development of seedling roots; although ordinary sprinkler spraying has improved to a certain extent, it often has the problem of uneven spraying, resulting in water shortage for some seedlings, and some seedlings may grow poorly due to excessive water accumulation.

[0004] In terms of light regulation, traditional nurseries usually rely on natural conditions or simple facilities such as sunshade nets, which makes it difficult to accurately control the intensity and duration of light, and cannot flexibly adjust according to the needs of seedlings at different growth stages. There is also a lack of effective means for temperature control. The seedlings cannot be cooled in time during high temperatures in summer, and cannot be well kept warm during low temperatures in winter, which has an adverse effect on the growth of seedlings.

[0005] In terms of air environment, it is difficult to accurately adjust the concentration of carbon dioxide in the nursery by traditional methods. As carbon dioxide is an important raw material for photosynthesis of seedlings, the appropriateness of its concentration is directly related to the growth rate and quality of seedlings. At the same time, there is a lack of special and effective measures for air purification in the nursery, and dust and harmful gases in the air may harm the healthy growth of seedlings.

[0015] A method for using a cultivation device for a gardening nursery comprises the following steps:

[0016] Step 1: First, plant the seedlings of the saplings evenly on the soil in the enclosure, and use the sensor components to detect the temperature and humidity, light intensity, carbon dioxide concentration, air quality and soil nutrients in the enclosure;

[0017] Step 2: In the early seedling growth stage, water is introduced through the water diversion pipe. After the three-way valve is switched, the water enters all hollow shafts through the fixed ring, and then drips on the soil surface through the drip hole to realize the drip irrigation function. In the late seedling maturity stage, after the three-way valve is switched, the water enters the U-shaped liquid passing seat, enters the arc elbow through the bending pipe, and then sprays out through all the nozzles to realize the sprinkler irrigation. During sprinkler irrigation, the arc elbow will continuously swing back and forth to improve the uniformity of sprinkler irrigation;

In summer, strong sunlight can be blocked to reduce the temperature of the nursery. In winter, the temperature in the nursery can be maintained to provide a suitable growth environment for the seedlings.

[0019] Step 4: When it is necessary to adjust the carbon dioxide concentration in the enclosure, turn on the fan, introduce carbon dioxide through the first air inlet pipe, and use the exhaust pipe, annular air slot and exhaust port to evenly introduce carbon dioxide into the enclosure. When it is necessary to purify the air in the enclosure, open the switch valve of the second air inlet pipe, use the fan and the second air inlet pipe to introduce the internal air into the shell, filter it through the air purification filter, and then discharge it into the enclosure through the exhaust pipe.

[0020] The present invention provides a garden greening nursery cultivation device and a method of using the same. The device has the following beneficial effects:

[0021] 1. In the seedling growth stage, the present invention realizes drip irrigation through the cooperation of the water diversion pipe, the three-way valve, the fixing ring and the hollow rotating shaft, thereby avoiding damage to the seedlings caused by the impact of water flow. When the seedlings enter the mature stage, they can be switched to the sprinkler irrigation mode, which can not only increase the air humidity, but also clean the leaves of the seedlings, keep the leaves clean, and promote the normal physiological activities such as photosynthesis. In the sprinkler irrigation process, the water flow is used to drive the water wheel in the U-shaped liquid passing seat to rotate. Through the cooperation of a series of transmission parts such as gears, worms, and worm wheels, the bent pipe, the arc-shaped bent pipe and the high-pressure nozzle can swing back and forth, thereby improving the spraying range and spraying efficiency, and ensuring the comprehensiveness and uniformity of the irrigation.

[0022] 2. The present invention drives the pinion to rotate through a reduction motor, and drives the rotating ring to rotate through meshing transmission with the arc-shaped rack plate, thereby causing the round head pin to drive the cam frame, the hollow rotating shaft and the triangular opening and closing blades to rotate. By controlling the rotation angle of the triangular opening and closing blades, the opening and closing degree of the upper part of the enclosure can be accurately adjusted. In summer, strong sunlight can be blocked to reduce the temperature inside the enclosure. In winter, the heat dissipation rate can be reduced to achieve a heat preservation function.

[0023] 3. When introducing carbon dioxide, the present invention can evenly introduce it into the enclosure through the annular wind groove and the guide vane. At the same time, by opening the switch valve on the second air inlet pipe, the air in the enclosure can reversely enter the annular wind groove through the exhaust port, and then enter the shell through the air inlet and the second air inlet pipe. The air purification filter is used to remove dust and harmful gases in the air and then re-discharged into the enclosure, thereby realizing ventilation inside the enclosure. For some seedling varieties with higher requirements for air quality, it can better assist their growth. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example:

[0035] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a cultivation device for a garden greening nursery, such as Figure 1As shown, it includes a fence 1. The fence 1 serves as the external protective structure of the entire cultivation device and can provide a relatively independent and stable spatial environment for the growth of the seedlings inside. A plurality of hollow shafts 2 are evenly and movably installed on the inner upper side of the fence 1. These hollow shafts 2 are evenly distributed to ensure that different areas in the fence 1 can be more evenly covered during subsequent irrigation operations. A plurality of drip holes 46 are provided at the bottom ends of the hollow shafts 2. The arrangement of the drip holes 46 allows the water source to drip onto the soil surface below in a relatively uniform and slow manner, thereby avoiding damage to the seedlings due to excessive or concentrated water flow. The inner ends of the hollow shafts 2 are movably installed on the outer wall of the fixing ring 3, which serves to connect and support the hollow shafts 2. The function of the central rotating shaft 2 enables the hollow rotating shaft 2 to stably rotate on its outer wall and other activities. Triangular opening and closing blades 4 are fixedly installed on the outer diameter of the hollow rotating shaft 2. The existence of the triangular opening and closing blades 4 can not only adjust the ventilation, lighting and other conditions on the upper part of the enclosure 1 by adjusting the opening and closing angles in some cases, but also play a certain role in the overall structural stability of the device. An annular wind groove 12 is provided between the inner wall and the outer wall of the enclosure 1. The annular wind groove 12 provides a specific channel for the flow of air, which is convenient for the subsequent adjustment of the air environment in the enclosure 1. An air outlet 13 is provided at one end of the annular wind groove 12. The air outlet 13 serves as an outlet for air to be discharged from the annular wind groove 12. It cooperates with other components to realize directional air transportation. The annular wind groove 1 2 is provided with an air inlet 14, which is the entrance for outside air to enter the annular wind slot 12. Through the coordinated work with the air outlet 13 and other related components, the air circulation and other operations are completed. A plurality of exhaust ports 15 are evenly opened on the inner wall of the annular wind slot 12. The exhaust ports 15 can discharge the air in the annular wind slot 12 into the enclosure 1 according to a certain rule, thereby effectively adjusting the air environment in the enclosure 1. A guide blade 16 is fixedly connected to one side of the exhaust port 15, and the width of the guide blade 16 changes linearly. This special design of the guide blade 16 can make the air or other gases (such as carbon dioxide) discharged from the exhaust port 15 more evenly distributed in the enclosure 1, ensuring that the gas is in the enclosure. 1, the inner wall of the fixing ring 3 is installed with a fixing seat 25 through two fixing rods, and the fixing seat 25 is firmly connected with the fixing ring 3 through the fixing rods, providing a reliable support foundation for the subsequent installation of other components, and a U-shaped liquid-passing seat 26 is fixedly installed on the top of the fixing seat 25. The U-shaped liquid-passing seat 26 is an important transfer component in the water source transmission process and plays a key role in the entire irrigation system. A bending pipe 28 is movably installed on one side of the U-shaped liquid-passing seat 26. The bending pipe 28 can change its angle under a certain external force, so as to adjust the spray direction of the nozzle 41, etc., and an arc-shaped bent pipe 40 is fixedly installed at the end of the bending pipe 28. The special arc structure of the arc-shaped bent pipe 40 helps to expand the spray coverage of the nozzle 41.A plurality of nozzles 41 are evenly fixedly installed at the bottom of the arc-shaped curved pipe 40. The nozzles 41 are components that finally spray water in the form of a spray, and can spray water evenly on the seedlings in the enclosure 1 to meet the water demand of the seedlings during their growth.

[0036] In this embodiment, the outer ends of the hollow shaft 2 extend to the outer wall of the enclosure 1 and are fixedly installed with a cam frame 5. The cam frame 5 is closely connected to the hollow shaft 2, and can move synchronously with the rotation of the hollow shaft 2, and can serve as an intermediate connection structure for other components to drive the hollow shaft 2 to rotate. A straight slot hole 6 is opened on the upper side of the cam frame 5, and the straight slot hole 6 provides a specific channel for the subsequent insertion and movement of the round head pin 8, so that the round head pin 8 can slide relatively smoothly therein, thereby driving the cam frame 5 to realize rotation and other actions, and the enclosure 1 A rotating ring 7 is movably installed on the outside of the enclosure 1 through a rotating frame. The rotating ring 7 is installed on the outside of the enclosure 1 through the rotating frame and can rotate around a specific axis. The rotating movement can be transmitted to other related parts through the connection relationship with other parts. A round head pin 8 is fixedly connected to the outer end of the rotating ring 7 near each cam frame 5. One end of the round head pin 8 is firmly connected to the rotating ring 7, and the other end is inserted into the corresponding straight slot hole 6. When the rotating ring 7 rotates, the round head pin 8 can move in the straight slot hole 6, thereby driving the cam frame 5 to rotate.

[0037] Furthermore, an arc-shaped rack plate 9 is fixedly connected to one side of the inner wall of the rotating ring 7. The arc-shaped rack plate 9 is tightly combined with the rotating ring 7, and its special arc-shaped structure can achieve a good meshing transmission relationship with the subsequent pinion 11. A reduction motor 10 is fixedly installed on one side of the enclosure 1. The reduction motor 10, as a power source, can provide stable and adjustable power output for certain actions of the entire device. A pinion 11 is fixedly installed on the driving end of the reduction motor 10, and the pinion 11 is meshed and connected with the inner end of the arc-shaped rack plate 9. The pinion 11 is driven to rotate by the reduction motor 10, and the meshing transmission of the pinion 11 and the arc-shaped rack plate 9 can drive the rotating ring 7 to rotate, thereby realizing a series of component actions related to the rotating ring 7, such as driving the rotation of components such as the cam frame 5 through the round head pin 8.

[0038] Furthermore, a shell 17 is fixedly installed on the outer wall of the enclosure 1. The shell 17 serves as a relatively independent closed structure, and a plurality of air conditioning-related components are installed inside, providing a relatively closed and stable environment for air processing and transportation. A fan 18 is fixedly installed on one side of the interior of the shell 17. The fan 18, as a power provider for air flow, can extract and transport the outside air or the inside air as needed. An exhaust duct 19 is fixedly connected to the output end of the fan 18, and the end of the exhaust duct 19 passes through the outer wall of the shell 17 and is connected to the air outlet 13. The exhaust duct 19 accurately transports the air output by the fan 18 to the air outlet 13, so that the air can enter the annular wind groove 12 for subsequent flow and distribution operations. A first air inlet duct 20 is fixedly connected to one side of the outer end of the shell 17. The first air inlet duct 20 serves as one of the channels for the outside air to enter the shell 17 , plays an important role when it is necessary to introduce specific gases (such as carbon dioxide). A second air inlet pipe 21 is fixedly connected to the other side of the outer end of the shell 17, and the end of the second air inlet pipe 21 is connected to the air inlet 14. The second air inlet pipe 21 is the channel for the air in the enclosure 1 to enter the shell 17. By cooperating with the first air inlet pipe 20 and other related components, air circulation and purification operations are realized. A switch valve 22 is fixedly installed on the outer diameter of the first air inlet pipe 20 and the second air inlet pipe 21. The switch valve 22 can control the opening and closing state of the first air inlet pipe 20 and the second air inlet pipe 21, so as to flexibly adjust the air inlet and outlet according to actual needs. An air purification filter 23 is fixedly installed on the other side of the interior of the shell 17. The air purification filter 23 can filter the air entering the shell 17 to remove dust and harmful gases therein, ensuring that the exhausted air is clean and meets the growth needs of seedlings.

[0039] Furthermore, a ring-shaped fill light strip 45 is fixedly installed on the inner wall of the enclosure 1. The ring-shaped fill light strip 45 can provide additional light supplement for the seedlings in the enclosure 1 when the light is insufficient, thereby meeting the light demand of the seedlings for growth. A sensor assembly 24 is also fixedly installed on one side of the inner wall of the enclosure 1. The sensor assembly 24 includes a temperature and humidity sensor, a light intensity sensor, a carbon dioxide concentration sensor, a gas sensor and a soil nutrient sensor. These different types of sensors can comprehensively and accurately monitor various environmental indicators such as temperature and humidity, light intensity, carbon dioxide concentration, air quality and soil nutrients in the enclosure 1, so as to timely adjust and optimize various functions of the cultivation device according to the monitoring results, thereby providing the most suitable growth environment for the seedlings.

[0040] Furthermore, a first branch pipe 27 is fixedly connected to the other side of the U-shaped liquid-passing seat 26. The first branch pipe 27 serves as a channel for transmitting water from the U-shaped liquid-passing seat 26 to other components, and can stably transport water to the next component. The end of the first branch pipe 27 is fixedly installed at one end of a three-way valve 42. The three-way valve 42 is a key component that can change the direction of water flow. It can reasonably distribute and guide the water flow according to different stages of seedling growth (such as seedling stage and mature stage). A water diversion pipe 43 is fixedly installed on the top of the three-way valve 42. The water diversion pipe 43 serves as a water source introduction pipeline for the entire irrigation system, and can introduce external water into the three-way valve 42. A second branch pipe 44 is fixedly installed at the bottom of the three-way valve 42 and the second branch pipe 44 is connected to the inside of the fixing ring 3. The second branch pipe 44 can transport the water source distributed by the three-way valve 42 to the fixing ring 3, and then distribute the water to each hollow rotating shaft 2 through the fixing ring 3.

[0041] Furthermore, a water wheel 29 is movably installed on one side of the U-shaped liquid-passing seat 26 near the bending tube 28. When the water flows through the U-shaped liquid-passing seat 26, the water wheel 29 can rotate due to the impact force of the water flow, thereby converting the energy of the water flow into mechanical energy to provide power for subsequent transmission components. A transmission chamber 30 is fixedly connected to the middle of the U-shaped liquid-passing seat 26. The transmission chamber 30 is a relatively closed space with multiple transmission components installed inside, which provides a stable environment for the meshing transmission between these components. The middle of the water wheel 29 extends to the inside of the transmission chamber 30 through a short shaft and is fixedly installed with a driving gear 31. The driving gear 31 rotates synchronously with the water wheel 29, and its rotational motion can be transmitted to other components through a meshing relationship with other gears. A driven gear 32 is movably installed on the lower side of the inner side wall of the transmission chamber 30 near one end of the water wheel 29, and the driving gear 31 and the inner side ends of the driven gear 32 are meshed and connected. The driven gear 32 rotates under the drive of the driving gear 31, and its rotational motion can be further transmitted through a meshing relationship with other components.

[0042] Furthermore, a worm 33 is fixedly installed in the middle of the driven gear 32. The worm 33 rotates with the rotation of the driven gear 32, and its special spiral structure can achieve a good meshing transmission relationship with the subsequent worm wheel 35. A transmission shaft 34 is movably installed in the inner middle of the transmission chamber 30. The transmission shaft 34 is a component that can transmit rotational power. Different transmission components can be installed at both ends of the transmission shaft 34 to achieve power transmission and conversion. A worm wheel 35 is fixedly installed on the outer diameter of the middle part of the transmission shaft 34, and the worm wheel 35 is meshed and connected with the inner end of the worm 33. The worm wheel 35 rotates under the drive of the worm 33, and its rotation can further affect the rotation state of the transmission shaft 34. Quarter-bevel gears 36 are fixedly installed on the outer diameters of both sides of the transmission shaft 34, and the meshing tooth positions of the two quarter-bevel gears 36 are staggered. This special design of the quarter-bevel gears 36 enables the two quarter-bevel gears 36 to intermittently achieve meshing transmission with the subsequent transmission bevel gear 38 when the transmission shaft 34 rotates. , so as to achieve a specific transmission effect, a rotating rod 37 is movably installed on one side of the U-shaped liquid-passing seat 26 away from the bending tube 28. The rotating rod 37 can perform a certain rotation operation at its installation position, and its rotation action can be transmitted to other related components through the connection relationship with other components. The end of the rotating rod 37 extends to the inside of the transmission chamber 30 and is fixedly installed with a transmission bevel gear 38. The transmission bevel gear 38 is a key component for realizing meshing transmission with the quarter bevel gear 36, which can receive the power transmitted by the quarter bevel gear 36 and convert it into the rotation power of the rotating rod 37. The outer end of the transmission bevel gear 38 is meshed and connected with the inner ends of the two quarter bevel gears 36. One end of the U-shaped connecting rod 39 is fixedly installed on the outer diameter of the middle part of the rotating rod 37, and the other end of the U-shaped connecting rod 39 is fixedly installed on the outer diameter of the bending tube 28. The rotation of the rotating rod 37 drives the U-shaped connecting rod 39 to move, thereby driving the bending tube 28 to achieve angle changes and swing back and forth, thereby improving the spraying range and spraying efficiency.

[0043] A method for using a cultivation device for a garden greening nursery, characterized in that it comprises the following steps:

[0044] Step 1: First, plant the seedlings of the saplings evenly on the soil in the enclosure 1, and use the sensor assembly 24 to detect the temperature and humidity, light intensity, carbon dioxide concentration, air quality and soil nutrients in the enclosure 1;

[0045] Step 2: In the early seedling growth stage, water is introduced by the water diversion pipe 43. After the three-way valve 42 is switched, the water enters all hollow shafts 2 through the fixing ring 3, and then drips on the soil surface through the drip hole 46 to realize the drip irrigation function. In the late seedling maturity stage, after the three-way valve 42 is switched, the water enters the U-shaped liquid passing seat 26, enters the arc-shaped curved pipe 40 through the bending pipe 28, and then is sprayed out through all the nozzles 41 to realize the sprinkler irrigation. During the sprinkler irrigation, the arc-shaped curved pipe 40 will continuously swing back and forth to improve the uniformity of the sprinkler irrigation.

[0046] Step 3: When the temperature and light intensity in the enclosure 1 need to be controlled, the reduction motor 10 drives the pinion 11 to rotate, and cooperates with the arc-shaped rack plate 9, the rotating ring 7 and other structural transmissions to drive all the hollow shafts 2 and the triangular opening and closing blades 4 to rotate, and adjust the opening and closing degree of the upper part of the enclosure 1. In summer, it can block strong sunlight and reduce the temperature of the nursery. In winter, it can maintain the temperature in the nursery and provide a suitable growth environment for the seedlings;

[0047] Step 4: When it is necessary to adjust the carbon dioxide concentration in the enclosure 1, turn on the fan 18, introduce carbon dioxide through the first air inlet pipe 20, and use the exhaust pipe 19, the annular wind groove 12 and the exhaust port 15 to evenly introduce carbon dioxide into the enclosure. When it is necessary to purify the air in the enclosure 1, open the switch valve 22 of the second air inlet pipe 21, use the fan 18 and the second air inlet pipe 21 to introduce the internal air into the shell 1, filter it through the air purification filter 23, and then discharge it into the interior of the enclosure 1 through the exhaust pipe 19.

[0048] Working principle: First, plant the seedlings of the saplings evenly on the soil in the enclosure 1, and use the sensor assembly 24 to detect the temperature and humidity, light intensity, carbon dioxide concentration, air quality and soil nutrients in the enclosure 1. In the early stage of seedling growth, use the water pipe 43 to introduce water. After the three-way valve 42 is switched, the water enters the fixed ring 3 through the second branch pipe 44, and then enters all the hollow shafts 2 through the fixed ring 3. The water is dripped on the soil surface through the drip hole 46 at the bottom of the hollow shaft 2 to achieve drip irrigation and avoid water flow impact and damage to the seedlings. In the later stage, the seedlings enter the mature stage. At this time, the water is introduced through the water pipe 43. After the three-way valve 42 is switched again, the water enters the U-shaped liquid seat 26 through the first branch pipe 27, and finally passes through the bending pipe The water 28 enters the arc-shaped curved pipe 40 and is sprayed out by all the nozzles 41 on the arc-shaped curved pipe 40 to realize the sprinkler irrigation. The sprinkler irrigation can not only increase the air humidity, but also clean the blades. At the same time, when the water source passes through the U-shaped liquid-passing seat 26, it will drive the water wheel 29 to rotate, and the driving gear 31 is driven to rotate through the water wheel 29. The rotating driving gear 31 is meshed with the driven gear 32 to drive the worm 33 to rotate. The worm 33 is meshed with the worm wheel 35, thereby driving the transmission shaft 34 and the quarter bevel gears 36 on both sides of the transmission shaft 34 to rotate. Since the meshing teeth of the two quarter bevel gears 36 are staggered, when the transmission shaft 34 rotates, the two quarter bevel gears 36 are intermittently meshed with the transmission bevel gear 38 for transmission, thereby driving The movable rotating rod 37 swings back and forth, and the swinging rotating rod 37 drives one end of the U-shaped connecting rod 39 to follow the movement, thereby driving the bending pipe 28, the arc-shaped bending pipe 40 and the high-pressure nozzle 41 to swing back and forth, thereby improving the spraying range and spraying efficiency. When it is necessary to control the temperature and light intensity in the enclosure 1, the reduction motor 10 drives the pinion 11 to rotate, and the rotating pinion 11 meshes with the arc-shaped rack plate 9 to drive the rotating ring 7 to rotate. The rotating rotating ring 7 will drive all the round head pins 8 on the outer wall to move. Since the round head pins 8 are arranged in the straight slot holes 6, when the round head pins 8 move, the cam frame 5 will be driven to rotate, thereby driving the hollow shaft 2 and the triangular opening and closing blades 4 to rotate. By controlling the rotation angle of all the triangular opening and closing blades 4, The opening and closing degree of the upper part of the enclosure 1 can be controlled to facilitate the adjustment of the light intensity in the enclosure 1. In summer, the opening and closing degree can be controlled to block strong sunlight and reduce the temperature in the enclosure 1. In winter, the heat dissipation rate in the enclosure 1 can be reduced to achieve the heat preservation function and provide a suitable growth environment for the seedlings. When the carbon dioxide concentration in the enclosure 1 needs to be adjusted, the fan 18 and the switch valve 22 of the first air duct 20 are opened, and carbon dioxide is introduced through the first air inlet pipe 20, and then discharged into the annular wind groove 12 through the exhaust pipe 19. Since each exhaust port 15 is provided with a guide blade 16, and the width of the guide blade 16 changes in form, the discharge amount of carbon dioxide through each exhaust port 15 is basically the same, so that the carbon dioxide is evenly discharged into the enclosure 1.To improve the photosynthesis efficiency of all seedlings and thus improve the growth efficiency, when the air in the enclosure 1 needs to be purified, open the fan 18 and the switch valve 22 on the second air inlet pipe 21, and the air in the enclosure 1 will enter the annular wind slot 12 through the exhaust port 15 in the opposite direction, and then enter the shell 17 through the air inlet 14 and the second air inlet pipe 21. The air purification filter 23 inside the shell 17 is used to remove dust and harmful gases in the air, and finally the air is discharged back into the enclosure 1 through the exhaust pipe 19, so as to realize the ventilation work inside the enclosure 1. For some seedling varieties with higher requirements for air quality, it can better assist their growth.
