Description

Technical Field

[0001] The invention relates to the technical field related to pepper breeding, and in particular to a pepper breeding germination box with a sterilization mechanism. Background Art

[0002] Pepper is an annual or limited perennial herb that prefers a warm, moderately humid, and sunny environment. Germination is a key step in pepper cultivation. Good seedlings determine subsequent pepper growth, quality, and yield. During the germination phase, the key is to regulate temperature, humidity, and maintain appropriate light. Pepper seeds need to be germinated and soaked before sowing. Drain the soaked seeds, keep them moist, and germinate them to ensure they are breathable and evenly heated. Germination typically takes about 5-8 days, with the first true leaf appearing about 15 days later. The seedling stage begins when the flower buds appear. The ideal temperature for germination is 25-30 degrees Celsius.

[0003] In traditional actual operation process, often directly seed soaking process back seed cloth bag and plastic film wrap are placed under electric light, under the sun, in electric heating blanket, hot water side and other heat source places to germinate, need to open ventilation every day in the germination process, easily affect seed germination rate and even the phenomenon of not sprouting.Therefore in existing processing mode, pepper seed is in order to ensure that temperature and humidity are stable when germination, generally can adopt breeding device, use reasonable seedling raising device to improve the cultivation efficiency and the seedling quality of pepper seedling, such as CN2768402Y crop seed germination bed comprises bed frame and sealing cover, in bed frame, culture box is set, in bed frame, culture box below is connected with base, is provided with heating element in base.Operating personnel can observe the germination situation of seed in bed frame outside germination bed, and by the temperature in control box, accurately understand the germination situation of seed.

[0004] However, existing breeding equipment often focuses on temperature control while neglecting humidity, especially ventilation control. Most systems simply leave vents open or allow ventilation directly through the lid. Watering is often done by spraying water directly through the lid. Over time, the humid environment can easily breed harmful bacteria. Furthermore, the lack of disinfection and filtration of irrigation water and fertilizer solutions can easily lead to soil-borne diseases that affect breeding results. Furthermore, without ventilation control, prolonged periods of open ventilation inevitably lead to greater energy consumption for temperature control and heating. The prolonged circulation of untreated external air also increases the likelihood of harmful external bacteria. Frequent manual operation of opening and closing ventilation is inconvenient, while simple intelligent control further increases equipment costs, making it inconvenient for ordinary farmers to operate and use, hindering further promotion to the agricultural market.

[0005] In view of this, we conducted in-depth research on the above issues, which led to the emergence of this case. Summary of the Invention

[0006] The object of the present invention is to provide a germination box for pepper breeding with a sterilization mechanism to solve the problem in the above background technology that the breeding device lacks humidity, especially ventilation control, and is easily affected by harmful bacteria.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: a germination box for pepper breeding with a sterilization mechanism, comprising a box body and a breeding chamber inside the box body for placing breeding trays;

[0008] A sterilization chamber is provided at the inner side end of the box body, and an ultraviolet disinfection lamp is installed on the inner wall of the sterilization chamber. The sterilization chamber and the breeding chamber are both closed independent areas;

[0009] An external vent is provided on the outside of the sterilization chamber, and a filter screen is embedded in the outer surface of the sterilization chamber, the filter screen corresponds to the position of the external vent; an internal vent is provided between the sterilization chamber and the breeding chamber, and movable covers are provided at the external vent and the internal vent, and the movable covers form a rotating opening and closing structure at the external vent and the internal vent;

[0010] The sterilization chamber is provided with a water storage tank and a movable water tank, and the movable water tank is arranged to move up and down below the water storage tank. A support spring is provided between the movable water tank and the bottom of the inner side of the box body. A water outlet is provided on the bottom surface of the water storage tank to fill water into the movable water tank, and a throttle valve is provided at the water outlet to control the flow rate of water drops. The total weight of the water filled in the movable water tank increases the downward pressure of the support spring.

[0011] A trigger-type delay switch is provided below the movable water tank, and the trigger-type delay switch is electrically connected to a ventilation fan and a water supply peristaltic pump driven by a drive motor, and the delayed opening and closing of the ventilation fan and the water supply peristaltic pump are controlled by pressing the trigger-type delay switch downwards of the movable water tank;

[0012] The ventilation fan is installed between the breeding chamber and the sterilization chamber;

[0013] Drip irrigation hoses are evenly distributed in the breeding warehouse, and the bottom side end of the movable water tank is connected with a water supply pipe, and a water supply peristaltic pump is installed between the drip irrigation hose and the water supply pipe.

[0014] Preferably, a closed cover is hinged on the top of the breeding chamber, and the surfaces of the closed cover, the water storage tank and the movable water tank are all light-transmitting panels.

[0015] By adopting the above technical solution, the breeding chamber is combined with the closed cover to form a complete closed breeding space. At the same time, the translucent panel of the closed cover does not affect the normal lighting requirements. When no lighting is required in the initial stage, a blackout curtain can be covered. The water tank and movable water tank located in the sterilization chamber use translucent panels to facilitate the sterilization of the internal water.

[0016] Preferably, a drain plate is fixed inside the breeding bin, and an overhead layer is left below the drain plate for the breeding tray to be placed overhead on the drain plate.

[0017] By adopting the above technical solution, the breeding tray is placed overhead through the drain plate to prevent excessive humidity or water accumulation in the breeding tray, while leaving enough space for air circulation.

[0018] Preferably, the water storage tank is provided with an addition port at the top of the tank body for adding aqueous solvents such as disinfectants, and a sealing cover is threadedly connected to the addition port.

[0019] By adopting the above technical solution, water can be pre-filled into the water tank through the addition port, so as to continuously drip water into the movable water tank through the water outlet. At the same time, auxiliary water solvents such as disinfectants can also be added to the water tank through the addition port.

[0020] Preferably, the movable cover is a disc-shaped structure, and fan-shaped ventilation slots and wind shields are evenly distributed radially on the surface of the movable cover, and the ventilation slots and wind shields are alternately arranged;

[0021] The outer vents and the inner vents are both fan-shaped grid structures, and the outer vents and the inner vents are respectively consistent with the corresponding ventilation slots and windshields;

[0022] The movable cover plate forms a rotating structure with the corresponding central axis of the outer vent and the inner vent as the axis, and the maximum rotation angle of the movable cover plate is the sum of the central angles of the ventilation slot and the wind shield.

[0023] By adopting the above technical solution, the movable cover is coordinated with the external vents and the internal vents to perform movable opening and closing adjustment. When the external vents and the internal vents correspond to the ventilation slots, the airflow at both ends can be kept normal and unobstructed for ventilation. When the external vents and the internal vents correspond to the wind shield, the airflow on both sides is closed and combined to effectively avoid external pollution.

[0024] Preferably, a lifting guide rail is provided on the side of the sterilization chamber, and the lifting guide rail is parallel to the central axis of the support spring, and the movable water tank forms a lifting and sliding structure along the lifting guide rail.

[0025] By adopting the above technical solution, the movable water tank is provided with a stable lifting space through the lifting guide rail, and at the same time the support spring maintains elastic support for the movable water tank. As the weight of the water in the movable water tank increases, the movable water tank presses down the support spring and moves downward along the lifting guide rail. When the equipment is supplied with water through the drip irrigation hose, the water in the movable water tank is discharged and the weight is reduced, and the movable water tank moves up and reset along the lifting guide rail under the action of the support spring.

[0026] Preferably, synchronous movable frames are fixed on both sides of the movable water tank, and the synchronous movable frames on the left and right sides of the movable water tank are respectively fitted with the side damping of the movable cover plate at the outer vent and the movable cover plate at the inner vent. The fitting damping is greater than the rotation damping of the movable cover plate, which can drive the rotation adjustment of the movable cover plate. At the same time, the fitting directions of the synchronous movable frames and the movable cover plates on both sides are opposite;

[0027] When the movable water tank rises, it drives the synchronous movable frame to deflect the movable cover at the inner vent to keep the inner vent open, and at the same time, the movable cover at the outer vent is deflected to keep the outer vent closed. When the movable water tank descends, the opposite is true.

[0028] By adopting the above technical solution, the opening and closing of the movable covers at the external vents and the internal vents are synchronously adjusted through the lifting and lowering displacement of the movable water tank in coordination with the synchronous movable frame. At the same time, the opening and closing directions of the movable covers at the external vents and the internal vents are opposite. When the synchronous movable frame moves up with the movable water tank, the external vents are closed and the internal vents are opened, and the ventilation fan can ventilate the clean fresh air in the breeding chamber and the sterilization chamber. When the synchronous movable frame moves down with the movable water tank, the external vents are opened and the internal vents are closed, the sterilization chamber is connected to the outside air, and the breeding chamber remains closed to effectively isolate external pollution.

[0029] Preferably, the ventilation fan includes a first ventilation fan and a second ventilation fan, and the first ventilation fan and the second ventilation fan are both provided with inner ventilation openings, and the fan blades of the first ventilation fan and the second ventilation fan are in opposite directions.

[0030] By adopting the above technical solution, the first ventilation fan and the second ventilation fan cooperate with each other in reverse, which can facilitate the formation of air circulation between the breeding chamber and the sterilization chamber for rapid ventilation.

[0031] Preferably, a synchronous transmission belt is connected between the shaft ends of the first ventilation fan and the second ventilation fan, and a driving motor is installed at the bottom of the box;

[0032] The drive motor forms a synchronous transmission structure for the first ventilation fan and the second ventilation fan through a synchronous transmission belt.

[0033] By adopting the above technical solution, the first ventilation fan and the second ventilation fan can be synchronously driven by a single drive motor in conjunction with a synchronous transmission belt.

[0034] Preferably, an extended drive rod is provided between the output shaft of the drive motor and the synchronous transmission belt, and the middle section of the extended drive rod is a worm section;

[0035] A transmission worm gear is provided at the shaft end of the water supply peristaltic pump, and the extended driving rod is meshed with the transmission worm gear through the worm segment to form a worm gear reduction transmission structure for the water supply peristaltic pump.

[0036] By adopting the above technical solution, the worm gear transmission structure with an extended drive rod can synchronously reduce the speed of the water supply peristaltic pump while the drive motor drives the first ventilation fan and the second ventilation fan. No additional drive equipment and control circuit are required, which is more energy-saving, efficient and convenient.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows: in actual application, the pepper breeding germination box with a sterilization mechanism is configured such that pepper seeds and nutrient soil are placed in a seedling tray and placed in the box body; while the seedlings are being grown in the sterilization space, water is supplied to the seeds by a water supply peristaltic pump in conjunction with a drip irrigation hose; a ventilation fan is used in conjunction with openable and closable external and internal vents for ventilation; stable intermittent control is performed in a manner similar to a drip clock, providing a better germination environment; the germination effect is significantly better than that of the traditional method, the germination rate of the seeds is increased by more than 5%, and the germination speed is significantly accelerated; the pepper seed cultivation equipment is made more convenient for ordinary farmers to operate and use, reducing costs and facilitating promotion; and the specific structural advantages include:

[0038] 1. An independent sterilization chamber corresponding to the breeding chamber is set up. The sterilization chamber is set up with a closed structure. At the same time, the water and gas in the chamber are isolated and sterilized. Water is slowly supplied through the water storage tank and the movable water tank. The ultraviolet disinfection lamp has sufficient time to effectively disinfect the air and water. At the same time, the external air is filtered through the filter plate and first enters the sterilization chamber and is separated from the breeding chamber, which effectively reduces direct external influences, reduces the breeding of harmful bacteria, reduces the impact of soil-borne diseases on pepper seedlings, and improves the quality of pepper seedling cultivation.

[0039] 2. By combining the water storage tank with the lifting structure of the movable water tank, a delayed trigger structure similar to a dripping clock is formed while storing and sterilizing water. The operation of the ventilation fan and the water supply peristaltic pump is intermittently controlled in combination with the trigger-type delay switch. The ventilation fan and the water supply peristaltic pump are turned off after a period of delay, and the movable water tank is reset to perform the next lifting cycle. At the same time, the movable water tank adjusts the opening and closing of the external vents and the internal vents synchronously through the synchronous movable frame during the lifting process. There is no need to set up a large number of intelligent control mechanisms. Only the throttle valve needs to be adjusted to adjust the water supply to achieve multiple controls at the same time, which reduces equipment costs and reduces the requirements for manual operation levels. It improves the efficiency of pepper seedling cultivation and is conducive to promotion to farmers.

[0040] 3. The ventilation fan is provided with a first ventilation fan and a second ventilation fan to cooperate with each other to exchange the air flow in the breeding chamber and the sterilization chamber. At the same time, the first ventilation fan and the second ventilation fan are synchronously driven by a synchronous transmission belt. At the same time, the driving motor synchronously drives the water supply peristaltic pump through the worm gear transmission structure to replenish water, and synchronously drives the ventilation and water supply operations. No additional driving mechanism and control equipment are required. The equipment has stable control performance and intermittent ventilation and water supply, which helps to maintain a good germination growth environment. It has the advantages of simple and practical structural design, energy saving and convenience for germination and cultivation of a small amount of seeds, etc. It meets the conditions required for seed germination, cultivates seeds to germinate quickly, and significantly improves the germination rate.

The delay function of the trigger-type delay switch 14 is mainly realized by the charging and discharging process of the capacitor. The trigger-type delay switch 14 triggers When the capacitor is charged, a signal is generated, which triggers the transistor to conduct, thereby charging a capacitor. After the capacitor is charged, a voltage is formed to maintain the conduction of the field effect tube, so that the drive motor 154 drives the ventilation fan 15 and the water supply peristaltic pump 16 to work continuously for a period of time. The discharge time of the capacitor determines the continuous power supply time of the drive motor 154.

The movable cover 8 is coordinated with the external vents 5 and the internal vents 7 to perform movable opening and closing adjustment. When the external vents 5 and the internal vents 7 correspond to the ventilation slots 81, the airflow at both ends can be kept normal and unobstructed for ventilation.
