Description

Technical Field

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

[0002] Pepper is an annual or limited perennial herb. It likes a warm growth environment, needs appropriate humidity and sufficient sunlight. In the process of pepper planting, breeding and germination are the key links. Good seedlings determine the subsequent growth of peppers and the quality and yield of planting. In the breeding and germination stage, the temperature and humidity are adjusted to maintain appropriate light. Pepper seeds need to be germinated and soaked before sowing. The soaked seeds should be drained and kept moisturized and warm for germination. The seeds are breathable and heated evenly. Germination generally takes about 5-8 days after sowing, and the first true leaf appears in about 15 days. When the flower buds appear, it is the seedling stage. The suitable temperature for seed germination is 25-30 degrees.

[0003] In the traditional actual operation process, the seeds are often directly wrapped with cloth bags and plastic film after soaking and placed under electric lights, under the sun, in electric heating blankets, hot water and other heat sources for germination. During the germination process, it is necessary to open the ventilation every day, but it is not easy to grasp the specific conditions such as temperature, humidity, ventilation, etc., which easily affects the seed germination rate and even the phenomenon of not germinating. Therefore, in the existing treatment method, pepper seeds are generally used in order to ensure that the temperature and humidity are stable during germination. Breeding devices are used, and the cultivation efficiency and seedling quality of pepper seedlings can be improved using reasonable seedling raising devices, such as CN2768402Y crop seed germination bed including bed frame and sealing cover, a culture box is set in the bed frame, and a base is connected below the culture box in the bed frame, and a heating element is provided in the base. The operator can observe the germination of the seeds in the bed frame outside the germination bed, and accurately understand the germination of the seeds by controlling the temperature in the box.

[0004] However, most existing breeding devices focus on temperature control and ignore humidity, especially ventilation control. Most of them directly leave open vents or directly ventilate by opening the cover. The watering method is often to spray water directly by opening the cover. During long-term use, harmful bacteria are easily generated in a humid environment. At the same time, there is no disinfection and filtration of irrigation water and fertilizer liquid, which is easy to induce soil-borne diseases and affect the cultivation effect. In addition, in the absence of ventilation control, if the ventilation is open for a long time, it will inevitably bring greater energy consumption required for temperature control and heating, and the long-term untreated external gas circulation will also increase the probability of external harmful bacteria. Frequent opening and closing of ventilation is inconvenient for manual operation, and simple intelligent control further increases the cost of equipment, which is not convenient for ordinary farmers to operate and use, and is not conducive to further promotion to the agricultural market.

[0005] In view of this, we conducted in-depth research on the above issues, which led to the present 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 purpose, 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; 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; 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; The sterilization chamber is provided with a water storage tank and a movable water tank inside, and the movable water tank is movably arranged under the water storage tank, a support spring is arranged between the movable water tank and the inner bottom of the box body, a water outlet is opened on the bottom surface of the water storage tank to fill water into the movable water tank, and a throttle valve is arranged at the water outlet to control the flow rate of water drops, and the total weight of the water filled in the movable water tank increases the downward pressure of the support spring; 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 driving motor, and the delay opening and closing of the ventilation fan and the water supply peristaltic pump is controlled by pressing the movable water tank downward to contact the trigger-type delay switch; The ventilation fan is installed between the breeding chamber and the sterilization chamber; 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.

[0008] Preferably, a closed cover is hinged on the top of the breeding bin, and the surfaces of the closed cover, the water storage tank and the movable water tank are all light-transmitting panels.

[0009] By adopting the above technical scheme, the breeding chamber cooperates with the closed cover to form a complete closed breeding space. At the same time, the light-transmitting 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 light-transmitting panels to facilitate the sterilization of the internal water.

[0010] Preferably, a drain plate is fixed inside the breeding bin, and an overhead layer is reserved below the drain plate for the breeding tray to be placed overhead on the drain plate.

[0011] 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.

[0012] Preferably, the water storage tank is provided with a adding port at the top of the tank body for adding aqueous solvents such as disinfectants, and a sealing cover is threadedly connected to the adding port.

[0013] By adopting the above technical scheme, water can be pre-filled into the water tank through the addition port, so as to continuously drip water to the movable water tank through the water outlet. At the same time, auxiliary water solvents such as disinfectants can also be added into the water tank through the addition port.

[0014] Preferably, the movable cover plate is a disc-shaped structure, and fan-shaped ventilation slots and wind shields are evenly distributed radially on the surface of the movable cover plate, and the ventilation slots and wind shields are alternately arranged; 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 wind shields; 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 plate.

[0015] By adopting the above technical solution, the movable cover is used to cooperate 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.

[0016] 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.

[0017] By adopting the above technical scheme, the movable water tank is provided with a stable lifting space through the lifting guide rail, and the supporting spring maintains elastic support for the movable water tank. As the deadweight of the water in the movable water tank increases, the movable water tank presses down the supporting spring and moves downward along the lifting guide rail. When the equipment is supplied with water through the drip irrigation hose, the deadweight of the water in the movable water tank is reduced after being discharged, and the movable water tank moves up and resets along the lifting guide rail under the action of the supporting spring.

[0018] 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, and 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, and at the same time, the fitting direction of the synchronous movable frame and the movable cover plates on both sides is opposite; When the movable water tank rises, it drives the synchronous movable frame to deflect the movable cover plate at the inner vent to keep the inner vent open, and at the same time, the movable cover plate at the outer vent is deflected to keep the outer vent closed, and vice versa when the movable water tank descends.

[0019] By adopting the above technical scheme, the opening and closing of the movable covers at the external vents and the internal vents are synchronously adjusted through the lifting and 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.

[0020] Preferably, the ventilation fan comprises 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.

[0021] By adopting the above technical solution, the first ventilation fan and the second ventilation fan cooperate with each other in reverse, so as to form an air circulation between the breeding chamber and the sterilization chamber for rapid ventilation.

[0022] 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; The driving motor forms a synchronous transmission structure for the first ventilation fan and the second ventilation fan through a synchronous transmission belt.

[0023] 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.

[0024] 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; A transmission worm gear is arranged 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 section to form a worm gear reduction transmission structure for the water supply peristaltic pump.

[0025] By adopting the above technical solution, the worm gear transmission structure with the 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.

[0026] 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 used to fill the pepper seeds and the nutrient soil into the seedling tray and put it into the box body. In addition to the normal temperature control of the constant temperature component, the seeds are replenished with water through the water supply peristaltic pump in cooperation with the drip irrigation hose, and the ventilation fan is ventilated in cooperation with the openable external vent and the internal vent. Stable intermittent control is performed in a manner similar to a drip clock, providing an optimal germination environment of constant temperature, moisture retention and stable ventilation. The germination effect is significantly better than 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 more convenient for ordinary farmers to operate and use, reducing costs and facilitating promotion. The specific structural advantages include: 1. An independent sterilization chamber corresponding to the breeding chamber is set up. The sterilization chamber is set up with a closed structure, and the water and gas in the chamber are isolated and sterilized at the same time. The 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 water body. At the same time, the external air is filtered through the filter plate and first enters the sterilization chamber to separate it from the breeding chamber, which effectively reduces direct external influences, reduces the growth of harmful bacteria, reduces the impact of soil-borne diseases on pepper seedlings, and improves the quality of pepper seedling cultivation.

[0027] 2. Through the lifting structure of the water storage tank and 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 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 used to adjust the water supply to achieve the regulation of water supply and ventilation at the same time, which reduces the equipment cost and the requirements for manual operation level, improves the efficiency of pepper seedling cultivation, and is conducive to promotion to farmers.

[0028] 3. The ventilation fan is provided with a first ventilation fan and a second ventilation fan to cooperate with each other to exchange the airflow in the breeding chamber and the sterilization chamber. 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 a worm gear transmission structure to replenish water. The ventilation and water supply operations are synchronously driven without the need for additional driving mechanisms and control equipment. The equipment has stable control performance and intermittent ventilation and water supply, which helps to maintain good temperature control performance. It has the advantages of simple and practical structural design, energy saving and convenience for germination and cultivation of a small amount of seeds. It is easy to control temperature, ventilate and moisturize, meets the conditions required for seed germination, cultivates seeds that germinate quickly, and significantly improves the germination rate.

The breeding chamber 2 cooperates with the closed cover plate 19 to form a complete closed breeding space. At the same time, the translucent panel of the closed cover plate 19 does not affect the normal lighting requirements. When no lighting is required in the initial stage, a blackout curtain can be covered, and the translucent panels of the water storage tank 9 and the movable water tank 10 located in the sterilization chamber 3 can also facilitate the sterilization of the internal water body.

The breeding tray is placed in the air by means of the drain plate 20, so as to avoid excessive humidity or water accumulation in the breeding tray, while leaving enough space for air circulation.

[0033] Combination Figure 1-Figure 3 As shown, a sterilization chamber 3 is provided at the inner side end of the box body 1, and an ultraviolet disinfection lamp 4 is installed on the inner wall of the sterilization chamber 3. The sterilization chamber 3 and the breeding chamber 2 are both closed independent areas; a water storage tank 9 and a movable water tank 10 are provided inside the sterilization chamber 3. The water storage tank 9 is provided with an addition port 91 at the top of the box body 1 for adding water solvents such as disinfectants, and a sealing cover 92 is threadedly connected at the addition port 91.

An internal vent 7 is provided between the sterilization chamber 3 and the breeding chamber 2, and movable covers 8 are provided at the external vent 5 and the internal vent 7. The movable cover 8 forms a rotating opening and closing structure at the external vent 5 and the internal vent 7; a movable water tank 10 is arranged to be lifted and moved below the water storage tank 9, and a support spring 11 is provided between the movable water tank 10 and the inner bottom of the box body 1, and the storage tank 9 is provided with a support spring 11. The bottom surface of the water tank 9 is provided with a water outlet 12 to inject water into the movable water tank 10, and a throttle valve 13 is provided at the water outlet 12 to control the water drop flow rate, and the total weight of the water injected into the movable water tank 10 increases the downward pressure of the support spring 11; a trigger-type delay switch 14 is provided below the movable water tank 10, and the trigger-type delay switch 14 is electrically connected to a ventilation fan 15 driven by a drive motor 154 and a water supply peristaltic pump 16. The delay function of the trigger-type delay switch 14 is mainly realized by the charging and discharging process of the capacitor. When the trigger-type delay switch 14 is triggered, , a signal will be generated, and this signal will trigger the transistor to conduct, and then charge 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. By adjusting the capacity of the capacitor and the resistance value in the circuit, the delay time can be changed, so that the trigger delay switch 14‌ can be customized according to the specific specifications of the equipment, in conjunction with the throttle valve 13 adjusts the water supply flow rate, adjusts the pressing time of the movable water tank 10 accordingly, and adaptively adjusts the water supply ventilation frequency according to the water supply ventilation demand.

[0035] Combination Figure 5-Figure 10As shown, the movable cover plate 8 is a disc-shaped structure, and the surface of the movable cover plate 8 is radially and evenly distributed with fan-shaped ventilation slots 81 and wind shields 82, and the ventilation slots 81 and wind shields 82 are alternately arranged; the outer vent 5 and the inner vent 7 are both fan-shaped grid structures, and the outer vent 5 and the inner vent 7 are respectively consistent with the corresponding ventilation slots 81 and wind shields 82; the movable cover plate 8 is respectively formed with the corresponding outer vent 5 and the inner vent 7 center axis as the axis to form a rotating structure, and the maximum rotation angle of the movable cover plate 8 is the sum of the central angles of the ventilation slots 81 and the wind shield 82. The movable cover plate 8 is coordinated with the outer vent 5 and the inner vent 7 to perform movable opening and closing adjustment. When the outer vent 5 and the inner vent 7 correspond to the ventilation slots 81, the airflow at both ends can be kept normal and unobstructed for ventilation, and when the outer vent 5 and the inner vent 7 correspond to the wind shield 82, the airflow is closed on both sides to effectively avoid external pollution. A lifting rail 22 is provided on the side of the sterilization chamber 3, and the lifting rail 22 is parallel to the central axis of the support spring 11, and the movable water tank 10 forms a lifting and sliding structure along the lifting rail 22. The lifting rail 22 provides a stable lifting and lowering activity space for the movable water tank 10, and the support spring 11 maintains elastic support for the movable water tank 10. As the weight of the water in the movable water tank 10 increases, the movable water tank 10 presses down the support spring 11 and moves down along the lifting rail 22.

Synchronous movable frames 23 are fixed on the left and right sides of the movable water tank 10, and the synchronous movable frames 23 on the left and right sides of the movable water tank 10 are respectively fitted with the side damping of the movable cover plate 8 at the outer vent 5 and the movable cover plate 8 at the inner vent 7. The fitting damping is greater than the rotation damping of the movable cover plate 8, which can drive the rotation adjustment of the movable cover plate 8.
