Description

Technical Field

[0001] This utility model relates to the technical field of plant seed cultivation equipment, specifically a constant temperature chamber for the stratification treatment of Rhododendron indicum seeds. Background Technology

[0002] As a rare plant with high ornamental and ecological value, Rhododendron simsii has a low natural seed germination rate. Stratification is a key technical step to break seed dormancy and improve germination rate. During stratification, precise control of soil moisture is particularly important. Too high humidity can lead to seed hypoxia, mold, or even rot, while too low humidity cannot meet the physiological and metabolic needs of seed after-ripening. Both will significantly reduce seed vigor and subsequent germination rate.

[0003] However, the current humidity control methods of existing seed stratification treatment incubators have obvious limitations: most devices rely only on passive humidity monitoring or manual intervention, lacking the ability to actively and accurately control humidity. For example, some devices equipped with humidification functions can supplement water through atomizing nozzles, but when the soil moisture is too high, it is still necessary to manually pour out excess water or replace the substrate. This is not only cumbersome to operate, but also difficult to respond to humidity changes in real time. At the same time, manual adjustment has problems such as large lag and insufficient precision, which may cause the soil moisture to remain too high for a long time, thereby damaging the Rhododendron simsii seeds, such as causing seed mold and reducing germination rate and survival rate.

[0004] To address these issues, we provide a constant temperature chamber for the seed stratification treatment of Azalea blue. Utility Model Content

[0019] Furthermore, the active water absorption mechanism also includes: a second telescopic rod, the driving end of which is connected to the moving plate, the second telescopic rod being connected to the side of the constant temperature chamber via a support frame, and a rectangular groove being provided inside the moving plate, through which the water absorption strip can pass.

[0020] (iii) Beneficial effects:

[0021] Compared with existing technologies, this rhododendron seed stratification treatment constant temperature chamber has the following beneficial effects:

[0022] I. This azalea seed stratification treatment constant temperature chamber is equipped with an active water absorption mechanism. When the soil moisture sensor detects high soil moisture, the active water absorption mechanism can absorb some of the moisture in the soil to adjust the humidity level. Specifically, the first telescopic rod pushes the fixed plate upward, precisely controlling the depth of the water absorption strip embedded in the groove frame of the placement plate, thereby timely absorbing excess water from the soil. This achieves real-time and precise control of soil moisture, effectively avoiding damage to seeds caused by excessive soil moisture, providing a stable and suitable humidity environment for the seeds, and helping to improve the germination rate and survival rate. At the same time, the active water absorption mechanism, together with the soil moisture sensor and atomizing nozzle, realizes the automation of soil moisture regulation. It eliminates the need for frequent manual detection and adjustment of soil moisture by staff, which not only saves labor costs but also reduces the risk of soil moisture loss due to untimely or inaccurate manual operation.

[0023] II. This azalea seed stratification treatment constant temperature chamber features a movable plate. When the water-absorbing strip rises and embeds into the lower end of the placement plate, the rectangular groove of the movable plate is positioned directly above the water-absorbing strip. This ensures that the movable plate does not interfere with or obstruct the movement of the fixed plate. After the water-absorbing strip has absorbed water, it descends along with the fixed plate under the action of the first telescopic rod. Then, the second telescopic rod pushes the movable plate, causing the rectangular groove and the water-absorbing strip to be vertically misaligned. At this time, the first telescopic rod lifts the fixed plate, allowing the water-absorbing strip to come into contact with the movable plate. Under the pushing force of the first telescopic rod, the water-absorbing strip is squeezed, expelling the water inside. By promptly squeezing out the water from the water-absorbing strip, it can quickly restore its water-absorbing capacity, allowing it to continue absorbing water when soil moisture rises again. This ensures the continuity and stability of the active water absorption mechanism in regulating soil moisture, preventing the water-absorbing strip from becoming saturated and unable to absorb water, and ensuring that the soil moisture in the entire constant temperature chamber remains within the suitable range for azalea seed stratification treatment.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-7 As shown, this utility model provides a technical solution: a constant temperature chamber for stratification treatment of Rhododendron simsii seeds, including a constant temperature chamber 1. A constant temperature ventilation system is provided at the rear end of the constant temperature chamber 1, which creates a suitable temperature environment for the seeds by regulating the temperature and air circulation inside the chamber, ensuring that the seeds will not be affected by excessively high or low temperatures during the stratification process. Support legs are provided on both sides of the constant temperature chamber 1 to support and fix the entire constant temperature chamber 1. A door 9 is rotatably connected to the front end of the constant temperature chamber 1. A glass observation window is provided inside the door 9, which allows the operator to easily observe the cultivation and growth status of the Rhododendron simsii seeds inside the constant temperature chamber 1. An atomizing nozzle 11 is connected to the upper end of the constant temperature chamber 1. A connecting pipe 12 is connected to the upper end of the atomizing nozzle 11. The connecting pipe 12 is connected to an external water pipe. The atomizing nozzle 11 converts the water transported by the external water pipe into tiny droplets and sprays them into the chamber, thereby replenishing the moisture of the cultivation soil and increasing its humidity.

[0035] The constant temperature chamber 1 is equipped with a placement plate 2. Multiple soil moisture sensors 3 are installed on the upper end of the placement plate 2. Culture soil is piled on the placement plate 2. The placement plate 2 is bent to form multiple groove frames. Water permeable holes are opened on both sides of the groove frames. When the soil moisture is too high, the excess water can flow out through these water permeable holes, creating conditions for the active water absorption mechanism to absorb water. A sealing plate 10 is connected to the front end of the placement plate 2. A rubber sealing strip is provided at the connection between the sealing plate 10 and the constant temperature chamber 1. The sealing strip provides a good sealing effect. The sealing plate 10 is located at the lower end of the chamber door 9. A handle is provided on its outer end. The handle makes it easy to remove the entire placement plate 2 from the constant temperature chamber 1.

[0036] The constant temperature chamber 1 is equipped with an active water absorption mechanism, which includes: multiple water absorption strips 4, a fixing plate 5, a telescopic rod 6, a water receiving hopper 7, and a drain pipe 8.

[0037] The absorbent strip 4 has good water absorption and water retention properties. It can be inserted into the groove frame formed by the placement plate 2. The fixing plate 5 is provided with multiple groove tracks, and water-permeable holes are opened on both sides of the tracks. The absorbent strip 4 is located in the groove track of the fixing plate 5, thereby installing and fixing the absorbent strip 4. The driving end of the first telescopic rod 6 is connected to the lower end of the fixing plate 5 and is used to adjust the height position of the fixing plate 5 and the absorbent strip 4.

[0038] Water collection hopper 7 is connected to the lower end of constant temperature chamber 1, and fixing plate 5 is located at the upper end of water collection hopper 7. It is used to collect water flowing out from fixing plate 5. Drain pipe 8 is connected to the lower end of water collection hopper 7. A valve is installed in drain pipe 8. Support plate 13 is connected inside water collection hopper 7. No. 1 telescopic rod 6 is connected to the upper end of support plate 13 to install and fix No. 1 telescopic rod 6. A protective pipe 14 is connected to the outer end of No. 1 telescopic rod 6. The drive end of No. 1 telescopic rod 6 is located inside the protective pipe 14, which can protect No. 1 telescopic rod 6 and reduce its erosion by water flow.

[0039] The active water absorption mechanism also includes: a movable plate 15 and a second telescopic rod 16. The movable plate 15 is slidably connected inside the constant temperature chamber 1. The movable plate 15 is located between the placement plate 2 and the fixed plate 5. The side end of the movable plate 15 is located at the outer end of the constant temperature chamber 1. The driving end of the second telescopic rod 16 is connected to the movable plate 15. The second telescopic rod 16 is used to adjust the movable plate 15. The second telescopic rod 16 is connected to the side end of the constant temperature chamber 1 through a support frame to fix the position of the second telescopic rod 16. A rectangular groove 17 is opened in the movable plate 15, and the water absorption strip 4 can pass through the rectangular groove 17.

[0040] Working principle: When in use, azalea seeds are sown in the culture soil on the placement plate 2. The soil moisture sensor 3 monitors the moisture of the culture soil in real time and feeds the moisture information back to the control system. When the soil moisture sensor 3 detects that the soil moisture is too high, the control system issues a command to start the active water absorption mechanism. The drive end of the first telescopic rod 6 extends and pushes the fixed plate 5 to rise. As the fixed plate 5 rises, the water absorption strip 4 passes through the rectangular groove 17 of the moving plate 15 and gradually embeds into the groove frame of the placement plate 2. At this time, the excess water in the soil flows out through the water permeable holes on both sides of the groove frame of the placement plate 2 and is absorbed by the water absorption strip 4 by capillary action.

[0041] After the absorbent strip 4 finishes absorbing water, the drive end of the first telescopic rod 6 retracts, causing the fixed plate 5 and the absorbent strip 4 to descend. At this time, the second telescopic rod 16 starts to work, and its drive end extends, pushing the moving plate 15 to slide inside the constant temperature box 1. When it moves to the appropriate position, the rectangular groove 17 and the absorbent strip 4 are misaligned in the vertical direction. Then, the first telescopic rod 6 extends again, lifting the fixed plate 5 and the absorbent strip 4 to rise and come into contact with the solid part of the moving plate 15. As the first telescopic rod 6 continues to apply the thrust, the moving plate 15 and the absorbent strip 4 are squeezed, thereby squeezing out the water absorbed inside the absorbent strip 4. The water drips through the water holes on both sides of the groove track of the fixed plate 5 into the water collection hopper 7, and then is discharged through the drain pipe 8.

[0042] When the soil moisture sensor 3 detects that the soil moisture is too low, the control system will control the atomizing nozzle 11 connected to the external water pipe to start working. Water in the external water pipe is transported to the atomizing nozzle 11 through the connecting pipe 12, and the atomizing nozzle 11 converts the water into tiny droplets and sprays them into the constant temperature chamber 1.
