Description

Technical Field

[0001] This utility model relates to the field of heating and darkening chamber technology, specifically a heating and darkening chamber for industrial rice seedling raising. Background Technology

[0002] Double-cropping rice is a major production model in southern China. Early rice transplanting takes place in mid-March. Due to unstable temperature rises from February to March, with frequent periods of low temperatures lasting for several days, early rice seedling cultivation is difficult, resulting in uneven germination, weak seedlings, and susceptibility to diseases such as damping-off. The constant-temperature germination chambers used in production are expensive and have limited space, making them suitable only for small-scale crop seedling cultivation. They are not suitable for mechanized operations in rice factory seedling cultivation or large-scale socialized service production. Using heated, darkened, underfloor-heated rice factory seedling cultivation chambers can facilitate the early sowing of late rice, ensuring sufficient accumulated temperature for both early and late rice, which is beneficial for increased yield. However, existing technologies have drawbacks such as the lack of intelligent temperature and humidity control, high power consumption, and inconvenient filter replacement and cleaning. In view of these issues, this project was developed through in-depth research. Utility Model Content

[0003] The purpose of this utility model is to provide a heated and darkened underfloor heating chamber for industrial rice seedling raising, in order to solve the problems mentioned in the background art that the existing heated and darkened underfloor heating chamber for industrial rice seedling raising does not have intelligent temperature and humidity control, energy saving and easy filter disassembly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heated, darkened cellar for industrialized rice seedling raising, comprising a temperature and humidity sensor, an insulated wall chamber, and mounting blocks. A control panel is installed on the inner wall of one side below the insulated wall chamber. An exhaust box is connected to one side above the insulated wall chamber, and an air inlet box is installed on the other side above the insulated wall chamber. Fans are installed inside both the air inlet and exhaust boxes, and filters are installed on one side of each fan. Mounting holes are provided at the bottom of both the exhaust and air inlet boxes. Furthermore, mounting blocks are installed on the inner side of each mounting hole, and the top of each mounting block is fixedly connected to the filter screen. Sealing rings are installed on the outer walls of each mounting block. Temperature and humidity sensors are installed on the inner walls of both sides of the insulated wall chamber. An insulated rolling door is installed at one end of the insulated wall chamber. A movable seat is installed on the inner side of the upper end of the insulated wall chamber, and a connecting pipe is connected to one end of the movable seat. Spray nozzles are evenly connected to the bottom end of the connecting pipe. A water tank is installed on one side of the upper part of the insulated wall chamber, and a water pump is installed inside the water tank.

[0005] Preferably, a mounting frame is installed at the top of the insulated wall chamber, and photovoltaic panels are installed on both sides of the top of the mounting frame, and a storage battery is installed on the inner side below the mounting frame.

[0006] Preferably, a retaining plate is installed on the inner side of both ends of the mounting block, and a pressure plate is connected to the bottom end of each retaining plate. The inner wall of each mounting hole is provided with a retaining groove that mates with the retaining plate.

[0007] Preferably, one end of each inner plate of the mounting block is connected to a damper, and a return spring is installed on the outer wall of each damper.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model provides underfloor heating pipes, an exhaust box, and an air inlet box. The underfloor heating pipes are evenly laid beneath a cement floor, and an air source heat pump water heater is installed outdoors. The underfloor heating pipes heat the interior of the insulated wall, while the air inlet and exhaust boxes provide ventilation. Temperature and humidity sensors monitor the temperature and humidity inside the insulated wall. When humidity is too high, a fan in the air inlet box draws in air, and a fan in the exhaust box exhausts air, achieving dehumidification. A filter screen filters out impurities and dust. When humidity is below standard, a water pump draws water from the tank, which enters the connecting pipe through a flexible hose and is then sprayed out through multiple spray nozzles. A servo motor drives gears, which mesh with a rack and pinion to move the connecting pipe left and right in a circular motion, spraying water mist. This ensures efficient and uniform humidification inside the insulated wall, solving the problem of lacking intelligent temperature and humidity control.

The photovoltaic panel absorbs light energy and converts it into electrical energy, which is then stored in the storage battery. The storage battery can provide power to the insulated wall chamber, achieving environmental protection and energy saving, and solving the problem of high power consumption.

[0014] This utility model provides a pressure plate, a clamping plate, and a filter screen. By pressing the pressure plate at both ends and moving it inward, the damper and the return spring are squeezed and deformed. At the same time, the clamping plate moves inward away from the slot. Then, the mounting block in the mounting hole is pulled down, allowing the filter screen to be pulled out for replacement or cleaning, thus solving the problem of inconvenient filter screen disassembly.

A control panel 3 is installed on the inner wall of one side below the insulated wall chamber 15. An exhaust box 31 is connected to one side above the insulated wall chamber 15, and an air inlet box 14 is installed on the other side above the insulated wall chamber 15. Fans 5 are installed inside both the air inlet box 14 and the exhaust box 31. A filter screen 13 is installed on one side of each fan 5. Mounting holes 30 are provided at the bottom of both the exhaust box 31 and the air inlet box 14, and mounting blocks 27 are installed inside the mounting holes 30. The room is equipped with mounting blocks 27, the top of which is fixedly connected to the filter screen 13. The outer wall of the mounting blocks 27 is equipped with sealing rings 25. Temperature and humidity sensors 4 are installed on both inner walls of the insulation wall chamber 15. An insulation roller door 17 is installed at one end of the insulation wall chamber 15. A movable seat 19 is installed on the inner side of the upper end of the insulation wall chamber 15. A connecting pipe 7 is connected to one end of the movable seat 19. Spray nozzles 6 are evenly connected to the bottom end of the connecting pipe 7. A water tank 11 is installed on one side of the upper part of the insulation wall chamber 15. A water pump 12 is installed on the inner side of the water tank 11.

[0022] A mounting frame 10 is installed at the top of the heat-insulating wall chamber 15, and photovoltaic panels 9 are installed on both sides of the top of the mounting frame 10. A storage battery 8 is installed on the inner side below the mounting frame 10.

[0023] Specifically, such as Figure 1 As shown, when using this structure, the photovoltaic panel 9 absorbs light energy and converts it into electrical energy, which is then stored in the battery 8. The battery 8 can provide power to the insulated wall chamber 15, achieving environmental protection and energy saving.

[0024] Example 2: The inner sides of both ends of the mounting block 27 are equipped with a clamping plate 23, and the bottom end of the clamping plate 23 is connected to a pressure plate 29. The inner wall of the mounting hole 30 is provided with a groove 24 that cooperates with the clamping plate 23.

[0025] One end of the inner plate 23 of the mounting block 27 is connected to a damper 28, and a return spring 26 is installed on the outer wall of the damper 28.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, when using this structure, by pressing the pressure plates 29 at both ends inward, the damper 28 and the return spring 26 are squeezed and deformed. At the same time, the clamping plate 23 moves inward away from the clamping groove 24. Then, the mounting block 27 in the mounting hole 30 is pulled down, so that the filter screen 13 can be pulled down for replacement or cleaning.

[0027] Example 3: A cement floor 2 is laid on the inner side below the insulation wall chamber 15, and a floor heating pipe 1 is installed under the cement floor 2. An air source water heater 16 is installed on the lower side of one side of the insulation wall chamber 15, and both ends of the floor heating pipe 1 are connected to the air source water heater 16.

[0028] The output end of the water pump 12 is connected to a telescopic hose 22, and one end of the telescopic hose 22 is connected to one end of the connecting pipe 7;

[0029] A servo motor 20 is installed on the inner wall of the movable seat 19, and the output end of the servo motor 20 is connected to a gear 21 through a drive shaft. A rack 18 is meshed on the inner wall of the insulation wall chamber 15 on one side of the gear 21.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when using this structure, the underfloor heating pipes 1 are evenly laid under the cement floor 2, and an air source water heater 16 is installed outdoors. The underfloor heating pipes 1 heat the interior of the insulation wall chamber 15, and ventilation is achieved through the air inlet box 14 and the air outlet box 31. The temperature and humidity inside the insulation wall chamber 15 are monitored by the temperature and humidity sensor 4. When the humidity is too high, the fan 5 in the air inlet box 14 works to draw in air, and the fan 5 in the air outlet box 31 works to exhaust air, thus achieving dehumidification. Impurities and dust are filtered through the filter screen 13. When the humidity is lower than the standard, the water pump 12 works to draw water from the water tank 11. The water enters the connecting pipe 7 through the telescopic hose 22, and is then sprayed out through multiple spray nozzles 6. The servo motor 20 works to rotate the gear 21. The gear 21 meshes with the rack 18, causing the moving seat 19 to drive the connecting pipe 7 to move left and right in a circular motion to spray water mist, making the humidification inside the insulation wall chamber 15 efficient and uniform, and facilitating intelligent temperature and humidity control.

[0031] Working principle: When using this device, the stacked seedling trays are first delivered through the insulated roller door 17 using a forklift and placed on the cement floor 2 of the insulated wall chamber 15. The temperature is set to 37 degrees Celsius on the control panel 3. The early rice seedlings are then darkened and germinated for 60 hours. Through underfloor heating and air circulation, the temperature rises from the ground, keeping the entire dark chamber at a constant temperature. This method results in seedlings emerging 15 days earlier than traditional methods, with more uniform emergence, a higher germination rate, and a 15% saving in seed usage. The cement floor 2 above the underfloor heating pipes 1 is hardened, which facilitates mechanized operation and allows for large-scale darkening of rice seedlings. The dark chamber temperature increase in southern regions allows for early rice planting 15 days earlier, which is beneficial for early sowing of late rice and ensures sufficient accumulated temperature for both early and late rice, thus increasing yield.

[0032] Implementation steps for the first innovation point:

[0033] Step 1: By evenly laying the underfloor heating pipes 1 under the cement floor 2, and installing an air source water heater 16 outdoors, the underfloor heating pipes 1 heat the interior of the insulated wall chamber 15, and ventilation is achieved through the air inlet box 14 and the air outlet box 31. This allows for a constant temperature and ventilation in the dark chamber, which is beneficial for the dark germination of rice seedlings. In cold weather, it can shorten the dark germination time, which is conducive to the mechanized planting of early rice. Furthermore, the underfloor heating pipes 1 are laid under the cement floor 2, which is suitable for forklift and sowing machinery operation, thus improving production efficiency.

[0034] Step 2: The temperature and humidity inside the insulation chamber 15 are monitored by the temperature and humidity sensor 4. When the humidity is too high, the fan 5 in the air inlet box 14 is used to introduce air and the fan 5 in the air outlet box 31 is used to exhaust air, thereby achieving exhaust dehumidification. Impurities and dust are filtered through the filter screen 13.

[0035] Step 3: When the humidity is lower than the standard, the water pump 12 draws water from the water tank 11. The water enters the connecting pipe 7 through the telescopic hose 22 and is then sprayed out through multiple spray nozzles 6. The servo motor 20 drives the gear 21 to rotate. The gear 21 meshes with the rack 18, causing the moving seat 19 to drive the connecting pipe 7 to move left and right in a circular motion to spray water mist, making the humidification in the insulation wall chamber 15 efficient and uniform.

[0036] Implementation steps for the second innovation point:

[0037] The photovoltaic panel 9 absorbs light energy and converts it into electrical energy, which is then stored in the battery 8. The battery 8 can provide power to the insulated wall chamber 15, achieving environmental protection and energy saving.

[0038] The third innovation point implementation steps:

[0039] By pressing the pressure plates 29 at both ends and moving them inward, the damper 28 and the return spring 26 are squeezed and deformed. At the same time, the clamping plate 23 moves inward away from the clamping groove 24. Then, the mounting block 27 in the mounting hole 30 is pulled down, so that the filter screen 13 can be pulled down for replacement or cleaning.
