Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, specifically to an automatic humidification and cooling device for Dendrobium officinale cultivation greenhouses. Background Technology

[0002] Dendrobium, a precious traditional Chinese medicine, has extremely high requirements for environmental humidity and temperature, preferring a cool, humid environment. Currently, large-scale cultivation of Dendrobium mainly relies on multi-span greenhouses. To ensure the optimal environment inside the greenhouse, humidification and cooling are among the most critical management aspects. In existing technologies, greenhouse humidification and cooling systems mostly employ fixed spray systems. These systems typically consist of a water pump, multiple spray pipes fixedly installed on the upper part of the greenhouse frame, and multiple spray nozzles installed on the pipes. They are connected to humidity sensors and controllers for automatic control. When the sensors detect that the humidity is below a set value or the temperature is above a set value, the controller activates the water pump to spray.

[0003] The applicant discovered that fixed spray systems have significant shortcomings when used for humidification and cooling of Dendrobium orchids in greenhouses: the spray range is fixed and limited, and the droplets are mainly concentrated in the area directly below the spray head, which easily leads to a severely uneven distribution of humidity in the greenhouse space. The area near the spray head is too humid, while the area far from the spray head is not humidified enough, affecting the balanced growth of Dendrobium orchids. Therefore, we propose an automatic humidification and cooling device for Dendrobium orchid cultivation greenhouses. Utility Model Content

[0004] The purpose of this invention is to provide an automatic humidification and cooling device for Dendrobium cultivation greenhouses, which can solve the problem mentioned in the background art that the fixed spraying range of the fixed spraying system is fixed and limited, affecting the balanced growth of Dendrobium.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic humidification and cooling device for a Dendrobium officinale cultivation greenhouse, comprising a greenhouse roof frame and a greenhouse support frame, wherein the greenhouse roof frame and the greenhouse support frame are detachably connected by bolts, and a reciprocating spray mechanism is installed at the bottom of the greenhouse roof frame, wherein the reciprocating spray mechanism includes a drive motor, and a reciprocating lead screw is fixedly provided at one end of the output shaft of the drive motor, and a threaded sleeve is threadedly connected to the outer wall of the reciprocating lead screw, and a spray assembly is detachably connected to the bottom of the threaded sleeve.

[0006] By adopting the above technical solution, the reciprocating movement of the spray component can be achieved.

[0007] Preferably, a limiting slider is fixed at the bottom of the threaded sleeve, and a limiting groove is provided inside the greenhouse roof frame for the limiting slider to slide.

[0008] By adopting the above technical solution, the stability of the threaded sleeve during movement can be improved.

[0009] Preferably, the limiting slider has a T-shaped cross-section, and the length of the limiting slider is greater than the width of the greenhouse support.

[0010] By adopting the above technical solution, the threaded sleeve and spray assembly can be supported.

[0011] Preferably, the spray assembly includes a diverter pipe, which is detachably connected to the threaded sleeve by bolts. Water supply pipes are fixed on both sides of the outer wall of the diverter pipe. An atomizing nozzle is fixed at one end of the water supply pipe. Water is injected into one end of the diverter pipe through a water injection hose. The water injection hose is fixedly installed with the diverter pipe, and a filter mechanism is installed at one end of the water injection hose.

[0012] By adopting the above technical solution, it is possible to spray the Dendrobium orchids in the greenhouse.

[0013] Preferably, the filtration mechanism includes a filter box, a sealed cover is fixedly installed on the top of the filter box, a drain valve is fixedly installed on the outer wall of the filter box near the end of the water inlet hose, fixed seats are fixed on both sides of the inner wall of the filter box, a filter screen is provided inside the filter box, and a snap-fit ​​block is fixed at both ends of the filter screen to snap into the fixed seat. A water inlet hose is detachably connected to the end of the filter box away from the water inlet hose.

[0014] By adopting the above technical solution, the water entering the spray assembly can be filtered.

[0015] Preferably, the cross-section of the snap-fit ​​block is I-shaped, and a pull ring is fixed at the bottom of the snap-fit ​​block.

[0016] By adopting the above technical solution, the installed filter screen can be limited.

[0017] Compared with the prior art, the beneficial effects of this utility model are: Firstly, by setting up a reciprocating spray mechanism, the drive motor in the reciprocating spray mechanism drives the reciprocating screw, thereby realizing the reciprocating movement of the spray component, spraying water mist into the greenhouse space in a dynamic scanning manner, breaking the limitations of fixed spraying, greatly improving the uniformity of humidity and temperature in the greenhouse, which is conducive to the balanced growth of Dendrobium crops.

[0018] Secondly, by incorporating a spray assembly and a filtration mechanism, the use of a filter screen in the filtration mechanism effectively filters the water entering the water injection hose, preventing the atomizing nozzle from becoming clogged during use. The detachable connection between the fixing base and the snap-fit ​​block ensures the long-term effectiveness of the filtration mechanism during use, further guaranteeing the stability of the spray assembly during operation.

[0025] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0026] Please see Figures 1-4The diagram shows an automatic humidification and cooling device for a Dendrobium officinale cultivation greenhouse, including a greenhouse roof frame 1 and a greenhouse support frame 101. The greenhouse roof frame 1 and the greenhouse support frame 101 are detachably connected by bolts. A reciprocating spray mechanism 2 is installed at the bottom of the greenhouse roof frame 1. The reciprocating spray mechanism 2 includes a drive motor 201, which is detachably connected to the bottom of the greenhouse roof frame 1. A reciprocating lead screw 202 is fixed to one end of the output shaft of the drive motor 201, and a screw thread is threaded onto the outer wall of the reciprocating lead screw 202. The threaded sleeve 203 has one side in contact with the bottom of the greenhouse roof frame 1, which can limit the movement of the threaded sleeve 203. A limiting slider 204 is fixed at the bottom of the threaded sleeve 203. A limiting groove 2041 for the limiting slider 204 to slide is opened inside the greenhouse roof frame 1. The limiting slider 204 has a T-shaped cross-section, and the length of the limiting slider 204 is greater than the width of the greenhouse support 101. A spray assembly 205 is detachably connected to the bottom of the threaded sleeve 203. 05 includes a diversion pipe 2051, which is detachably connected to the threaded sleeve 203 by bolts. Water supply pipes 2052 are fixed to both sides of the outer wall of the diversion pipe 2051. An atomizing nozzle 2053 is fixed to one end of each water supply pipe 2052. The atomizing nozzle 2053 has a flow rate of 2-5 L / h and a working pressure of 0.2-0.5 MPa. The inner diameter of the water supply pipe 2052 is 8 mm to balance the atomization effect and coverage area. One end of the diversion pipe 2051 is connected to a water injection hose 2. Water is injected into the greenhouse 101 at point 054. The water injection hose 2054 is fixedly installed between the water injection hose 2054 and the branch pipe 2051. A filter mechanism 3 is installed at one end of the water injection hose 2054. This device uses a programmable logic controller (PLC, such as Siemens S7-200 series) as the core controller. Humidity sensors (e.g., Honeywell HIH-4000 series) and temperature sensors (e.g., DS18B20) are installed at multiple locations on the greenhouse support 101 to monitor the average environmental parameters inside the greenhouse. The controller has a preset humidity threshold of 70%±5% and a temperature threshold of 25°C±2°C. When the sensor data exceeds the threshold, the PLC outputs a signal to start the water pump (such as a centrifugal water pump with a flow rate ≥10L / min) and simultaneously starts the drive motor 201. It should be noted that the process algorithms and programs involved in the operation of the programmable logic controller, temperature sensor and humidity sensor in this utility model are not within the protection scope of this utility model, and the process algorithms and programs involved can be obtained by those skilled in the art through conventional technology. Therefore, they are only used for those skilled in the art to understand the application of the programmable logic controller, temperature sensor and humidity sensor in this utility model. When the sensor installed inside the greenhouse detects that the humidity is below the set value or the temperature is above the set value, the controller starts the water pump to draw water, which is then filtered by the filter mechanism 3 and injected into the diversion pipe 2051 through the water injection hose 2054. The water is then delivered through the diversion pipe 2051 and the water supply pipe 2052 to the atomizing nozzle 2053 to spray the Dendrobium orchids inside the greenhouse. Simultaneously, the drive motor 201 in the reciprocating spray mechanism 2 is activated, driving the reciprocating screw 202 to rotate inside the threaded sleeve 203. The threaded sleeve 203 drives the limiting slider 204 and the spraying component 205 to perform dynamic scanning spraying on the greenhouse through the atomizing nozzle 2053 under the limitation of the limiting groove 2041. Then, the reciprocating screw 202 is driven by the drive motor 201 in the reciprocating spraying mechanism 2, thereby realizing the reciprocating movement of the spraying component 205, spraying water mist into the greenhouse space in a dynamic scanning manner, breaking the limitations of fixed spraying, greatly improving the uniformity of humidity and temperature in the greenhouse, and promoting the balanced growth of Dendrobium officinale crops.

[0027] Please see Figures 3-5 The filter mechanism 3 shown in the figure includes a filter box 301. One end of the water inlet hose 2054 is detachably connected to the filter box 301. A sealing cover 3011 is fixedly installed on the top of the filter box 301. When the sealing cover 3011 is installed on the filter box 301, the inside of the filter box 301 is sealed and the locking block 304 is pressed by the sealing cover 3011. A drain valve 3012 is fixedly installed on the outer wall of the filter box 301 near the end of the water inlet hose 305. The drain valve 3012 is connected to the inside of the filter box 301. Both sides of the inner wall of the filter box 301 are fixedly equipped with... The filter box 301 is equipped with a filter screen 303 inside the fixed base 302. Both ends of the filter screen 303 are fixed with snap-fit ​​blocks 304 that snap-fit ​​with the fixed base 302. There is friction damping between the snap-fit ​​blocks 304 and the fixed base 302 to ensure the stability of the filter screen 303 during installation. The cross-section of the snap-fit ​​blocks 304 is I-shaped. A pull ring 3041 is fixed at the bottom of the snap-fit ​​blocks 304. The end of the filter box 301 away from the water injection hose 2054 is detachably connected to the water inlet hose 305. The water injection hose 2054, the filter box 301, and the water inlet hose 305 are connected. When filtering the water in the injection diversion pipe 2051, the water pumped by the water pump is first injected into the filter box 301 through the inlet hose 305, and impurities in the water are filtered through the filter screen 303. Then, the filtered water is fed into the diversion pipe 2051 through the water injection hose 2054. When the filter screen 303 needs to be replaced periodically, after opening the sealing box cover 3011, the pull ring 3041 drives the locking block 304 and the filter screen 303 to disengage from the limit of the fixing seat 302. Then, a new filter screen 303 is installed in the filter box 3051. When the inside of the filter box 301 needs to be cleaned, the drain valve 3012 can be opened to discharge the water containing impurities in the filter box 301. Then, through the use of the filter screen 303 in the filter mechanism 3, the water quality in the input water injection hose 2054 is effectively filtered, avoiding the phenomenon of the atomizing nozzle 2053 being blocked during use. The detachable connection between the fixed seat 302 and the snap-fit ​​block 304 ensures the long-term effectiveness of the filter mechanism 3 during use, and further ensures the stability of the spray assembly 205 during operation.
