Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure spray devices, in particular to an intelligent high-pressure spray device and method for preventing and treating gray mold of post-harvest cut rose flowers. Background Art

[0002] Rose cut flowers rank first among the four major cut flowers in the world, accounting for over one-third of the global cut flower industry's total output. Cut roses are a general term for modern rose varieties suitable for cut flower cultivation. Due to their large, beautiful flowers and diverse colors, they possess high economic value and are one of the most consumed flowers in the cut flower market. Gray mold is a necrotrophic fungal disease caused by Botrytis cinerea. When infecting plants, the pathogen's conidia, conidiophores, and hyphae serve as a source of infection. The gray mold layer forms on the infected area in the later stages of infection, hence the name. Gray mold is also known as the "cancer" of post-harvest roses. This is because the fungus is pathogenic at low temperatures. Yunnan, the main production area for cut roses, faces challenges with the separation between production and distribution, and transportation distances are long. Post-harvest handling and transportation of cut roses require a low-temperature, high-humidity environment. These conditions are essential for the outbreak of gray mold, and high humidity, in particular, is the dominant factor in the disease's development. The large number of conidia produced by diseased areas during humid conditions is the primary source of reinfection.

[0003] Currently, post-harvest treatment of gray mold in cut roses often involves mixing a gray mold agent in a large vat. Workers then immerse the entire flower head in the agent for three seconds, repeating this process twice until the entire flower head is completely coated. This is known as the "dip" treatment. Some companies also use traditional manual and electric sprayers for a so-called "soft" spray treatment.

[0004] Although the existing "dipping head" treatment ensures uniform immersion of the liquid medicine, it also has many disadvantages during operation. First, a large amount of gray mold agent needs to be configured. On the one hand, in order to ensure that all the flower heads are dipped and the flower heads cannot touch the bottom of the container, on the other hand, in order to facilitate manual operation, the gray mold agent is often configured to fill the entire container so that the liquid level is at the top of the container. However, the liquid medicine is often damaged due to contamination or volatilization of the liquid medicine, and the liquid medicine needs to be replaced every two days, which greatly increases the cost of medicine. In addition, a major cause of gray mold is high humidity. However, the "dipping head" treatment will increase the humidity of the flower heads due to immersion and make them difficult to dry. If directly pre-cooled, the humidity will continue, causing gray mold outbreaks, sales difficulties, brand damage and other immeasurable economic losses. If it is dried naturally, the industrial production time will be extended, and other risks and costs will be increased.

[0005] Existing "soft" spray treatments suffer from insufficient spray pressure, and both pressure and distance are manually controlled, resulting in uncontrollable processes. Insufficient spray pressure results in excessively large droplet size and a low deposition rate, failing to achieve the desired gray mold control effect. Furthermore, large droplet size and high liquid dosage lead to wasteful use of the spray, increasing costs. Manual control of both pressure and distance creates uneven droplet size, impacting subsequent post-harvest processes. Furthermore, the lack of splash protection and manual operation make the process less environmentally and operator-friendly.

[0006] In addition, different varieties of rose cut flowers have different petal thickness and surface structure, resulting in different resistance to the impact of pesticide spraying. Therefore, adjusting the spray pressure and distance according to the variety type can ensure the spraying control effect without causing obvious or invisible damage to the petals.

[0048] Example 1

[0049] like Figure 1 As shown, the present invention provides an intelligent high-pressure spray device for controlling gray mold of rose cut flowers after harvest, including a spraying module 1, a pressure supply module 2, a cut flower operating table 3, a controller 4 and a microcomputer information processing system 5.

[0050] like Figure 2As shown, the pressure supply module 2 is connected to the spraying module 1, and the nozzle 110 of the spraying module 1 is installed on the cut flower operating table 3. The microcomputer information processing system 5 collects real-time data of the pressure supply module 2 and the cut flower operating table 3 respectively and controls the operating status of the pressure supply module 2 and the cut flower operating table 3 respectively through the controller 4.

[0051] like Figure 3 As shown, the spraying module 1 includes a medicine mixing barrel 11, which has a feed inlet 12 and a water inlet 13 above it. A stirring motor 14 is installed on one side of the medicine mixing barrel 11. The output end of the stirring motor 14 is connected to a stirring paddle 15 located inside the medicine mixing barrel 11. The stirring paddle 15 is provided with at least a pair of blades to ensure that sufficient stirring is provided for the liquid medicine. A discharge port 16 is provided at the bottom of the medicine mixing barrel 11 and is connected to a booster pump 17. The output end of the booster pump 17 is connected to a mixing chamber 19. A first pressure gauge 18 is provided on the pipeline between the booster pump 17 and the mixing chamber 19, which can read the pressure provided by the spraying module 1 in real time. The output end of the mixing chamber 19 is connected to a nozzle 110. The nozzle 110 in this embodiment is a 0.8mm aperture atomizing nozzle with good atomization effect. Atomizing nozzles of different apertures can also be replaced according to different usage requirements.

[0052] like Figure 4 Shown, pressure provides module 2 to comprise air compressor 21, for providing air to increase air pressure.The output end of air compressor 21 is connected with air storage tank 22, and the output end of air storage tank 22 is connected with pressure regulating valve 23, and the signal receiving end of pressure regulating valve 23 is connected with controller 4, and controller 4 is connected with microcomputer information processing system 5, can be according to different Chinese rose varieties, after microcomputer information processing system 5 analysis and processing, control pressure regulating valve 23 by controller 4 automatically by pressure regulation to suitable size.The output end of pressure regulating valve 23 is connected with pressure stabilizing box 24, and the output end of pressure stabilizing box 24 is connected to mixing chamber 19.On the pipeline between pressure stabilizing box 24 and mixing chamber 19, be provided with second pressure gauge 25, can observe the pressure that module 2 provides equally in real time.

[0053] like Figure 5-7 As shown, the cut flower operation table 3 includes a frame 31, on which a chain plate conveyor 32 is provided. A conveyor motor 33 connected to a drive shaft 34 of the chain plate conveyor 32 is installed on the frame 31. A screw component mounting groove 312 connected to the frame 32 is installed on the side of the chain plate conveyor 32. A screw component mounting groove 312 is provided inside the screw component mounting groove 312. The lower end of the screw 313 is connected to a screw motor 314. The rotation of the screw motor 314 can drive the screw 313 to rotate synchronously. The screw motor 314 is connected to the controller 4, and the operating state of the screw motor 314 can be automatically controlled by the controller 4.

[0054] A screw nut mounting base 315 is movably connected to the lead screw 313. This base 315 can be moved up and down by the forward and reverse rotation of the lead screw motor 314. A crossbar 316 is connected to the outside of the lead screw nut mounting base 315, and the spray head 110 is mounted on this crossbar 316. Rotation of the lead screw 313 allows the lead screw nut mounting base 315 to move up and down on the lead screw 313, thereby automatically adjusting the height of the spray head 110. This makes it suitable for spraying different grades of roses (primarily cut roses graded by length).

[0055] An anti-splash system is installed on the frame 31, which includes a support frame 35 fixed on the frame 31. The left and right sides of the support frame 35 are acrylic panels. The front and rear sides of the support frame 35 are open structures and are both equipped with movable door components. An induction component is installed in front of the support frame 31.

[0056] The movable door assembly includes a roller shutter 36 fixed to one side of the support frame 35. One end of the roller shutter 36 is connected to a roller shutter drive motor 37 for driving the roller shutter 36 to rotate, thereby opening the front and rear openings of the support frame 35, facilitating the entry of the roses to be sprayed into the support frame 35. A spring return mechanism 38 is mounted on the opposite side of the roller shutter 36. When the roller shutter drive motor 37 stops working, the spring return mechanism 38 automatically resets the roller shutter 36, thereby closing the front and rear openings of the support frame 35. This blocks the liquid medicine during spraying, not only providing protection for the human body but also facilitating more comprehensive secondary collection of the liquid medicine. The roller shutter structures in this embodiment are all prior art, so they will not be described in detail here.

[0057] The sensing assembly includes an ultrasonic transmitter 310 and an ultrasonic receiver 311 mounted opposite each other on either side of the front end of the support frame 35. It also includes an infrared detector 39 mounted on the conveyor mechanism in front of the frame 31. The ultrasonic transmitter 310, ultrasonic receiver 311, and infrared detector 39 are all in communication with a microcomputer information processing system 5. When a rose to be sprayed approaches the device, it is first detected by the infrared detector 39. The microcomputer information processing system 5 then sends a command to the controller 4, causing the movable door assembly to open. When the rose to be sprayed approaches the ultrasonic transmitter 310 and ultrasonic receiver 311, the detected height information is transmitted to the microcomputer information processing system 5. After analysis and processing, the microcomputer information processing system 5 controls the rotation of the lead screw motor 314 through the controller 4, thereby automatically adjusting the spray head 110 to the appropriate height. The spray distance of the spray head 110 is generally selected to be 30-40 cm from the surface of the cut flower head, and the spray width is controlled to be 220 mm at a spray distance of 40 cm.

[0058] Below the chain conveyor 32, a liquid medicine recovery assembly is mounted on the frame 31 for secondary recovery of liquid medicine. This assembly includes a funnel-shaped stainless steel plate 317 mounted on the frame 31. A liquid medicine recovery bucket 318 is connected to the bottom of the plate 317. This secondary recovery of liquid medicine significantly reduces liquid medicine consumption and lowers costs.

[0059] The method for intelligent high-pressure spraying for preventing and controlling gray mold of cut rose flowers after harvest using the high-pressure spray device of this embodiment comprises the following steps:

[0060] S1. According to the current production method, first bundle the cut flowers cut in the field into packages of 80 branches and put them into the flower barrel.

[0061] S2. Water is injected into the medicine mixing barrel 11 through the water inlet 13. At this time, the medicine liquid is put into the medicine mixing barrel 11 in proportion according to the requirements of different brands of gray mold medicine. At this time, the stirring motor 14 is started again. The stirring motor 14 drives the stirring paddle 15 to rotate. The stirring paddle 15 evenly mixes the water and gray mold medicine in the medicine mixing barrel 11. The medicine is dispensed as needed according to production requirements and dispensed as needed.

[0062] S3. Start the air compressor 21 so that the air pressure in the gas cylinder 22 reaches above 0.4 MPa.

[0063] S4. Input the cut flower variety to be treated for gray mold after harvest into the microcomputer information processing system 5. The microcomputer information processing system 5 compares the data with the database and determines the output spray pressure.

[0064] S5, put the flower barrel containing cut flowers in S1 into the feeding conveyor part of the cut flower conveyor

[0065] S6, S1 The flower barrel containing cut flowers enters the cut flower operation table 3 driven by the feeding conveyor. At this time, the liquid medicine anti-splashing system begins to close and the spraying module 1 starts to work.

[0066] S7, S1 The flower barrels filled with cut flowers enter the discharge conveyor part under the drive of the chain plate conveyor belt 32 of the cut flower operation table 3, and move under the drive of the discharge conveyor part. The flower barrels filled with cut flowers are unloaded manually and enter the subsequent post-harvest operation.

[0067] In this example, three varieties, 'Peach Snow Mountain,' 'Purple Cloud Fairy,' and 'Aisha,' were used for a practical effect experiment. Cut flowers of each variety were divided into five groups, each with ten branches. All cut flowers were shortened to a uniform length, leaving only the flower heads and some branches. "Gray mold water" was diluted according to the packaging specifications and treated differently. After treatment, the cut flowers were aired until no visible water appeared on the surface. The flowers were then placed in a high-humidity moisturizing box and vase-arranged for observation. The treatments for each group are shown in the following table:

[0068] Table 1 Different “gray mold water” and different treatment methods

[0069]

[0070] During the vase period, photos were taken every day to record the phenotype of the cut flowers, and the outbreak time and level of gray mold were recorded.

[0071] Observation index: disease index = 100 × ∑ (number of samples at each level × representative value at each level) / (total number of samples surveyed × highest representative value) × 100%

[0072] Incidence rate = number of samples with disease / total number of samples × 100%

[0073] The experimental results are as follows Figure 8-12 As shown, it is proved that the high-pressure spray device of this embodiment has a better effect in spraying the liquid medicine.

[0074] Therefore, the present invention adopts the above-mentioned intelligent high-pressure spray device and method for preventing and controlling gray mold of rose cut flowers after harvest, which can automatically adjust the spraying height according to different varieties, greatly save the amount of medicine while ensuring the spraying effect, which is conducive to reducing costs, alleviating manual labor intensity, reducing harm to the human body, and improving work efficiency.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
