Description

Technical Field

[0001] This utility model belongs to the field of agricultural seedling technology, specifically relating to a rice seedling raising device with heat preservation and moisture retention functions. Background Technology

[0002] Agricultural seedling cultivation is a crucial first step in agricultural production. It refers to the process of cultivating robust and uniform seedlings in a suitable artificial environment before transplanting crops to the field. It directly affects the later yield, quality, and resistance to adverse conditions. Using seedling cultivation devices before mass planting makes it easier to control pests and diseases, cultivate well-developed seedlings with strong stems and no pests or diseases, and significantly improve the transplant survival rate. Existing seedling cultivation devices for rice cultivation can basically meet daily needs. During the cultivation process, temperature and humidity sensors need to be installed in the cultivation space to monitor the internal environment in order to ensure the stability of the cultivation environment. However, the installation position of the sensors is relatively fixed and the monitoring position cannot be adjusted. During the seedling cultivation process, different areas may have different environments due to factors such as water spraying and heating. Since the sensors cannot be moved, the monitoring data only represents the local environment and it is difficult to accurately adjust the overall situation inside the device. At the same time, the seedling cultivation pots are basically placed inside the device, which affects the convenience of daily operations such as turning the soil and fertilizing. Therefore, it is necessary to design a rice cultivation seedling cultivation device with heat preservation and moisture retention functions. Utility Model Content

[0003] The purpose of this utility model is to provide a rice seedling raising device with a simple structure and reasonable design that has heat preservation and moisture retention functions in order to solve the above problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A rice seedling raising device with heat preservation and moisture retention functions includes a bottom shell, a rotary motor installed in the bottom shell, a rotary support fixedly connected to the output end of the rotary motor, a removal mechanism provided on the rotary support, a seedling pot installed on the removal mechanism, and a sealing cover provided on the top of the bottom shell, and an adjustment mechanism provided in the sealing cover.

[0006] As a further optimization of this utility model, the removal mechanism includes support bars evenly arranged on a rotating bracket, a support plate slidably connected to the support bars, and the seedling pot mounted on the support plate.

[0007] As a further optimization of this utility model, a guide rod is slidably connected in the support plate, and the guide rod is fixed on the rotating bracket. A connecting block is fixed at the bottom of the support plate, and the connecting block is connected to the lead screw. The lead screw is rotatably connected to the bottom of the rotating bracket, and the lead screw is fixedly connected to the output end of the lead screw motor, which is fixed on the rotating bracket.

[0008] As a further optimization of this utility model, the adjustment mechanism includes a gear ring rotatably connected in the enclosed cover, the gear ring meshing with a gear, and the gear being fixed on the output end of the adjustment motor, the adjustment motor being fixed on the top of the enclosed cover.

[0009] As a further optimization of this utility model, a mounting ring is fixed to the bottom of the toothed ring, and mounting brackets are evenly arranged at the bottom of the mounting ring. A lifting cylinder is fixed in the mounting bracket, and an adjusting plate is fixedly connected to the output end of the lifting cylinder. Sensing units are symmetrically installed on the adjusting plate.

[0010] As a further optimization of this utility model, a sealing door is slidably connected to one side of the sealing cover, a handle is provided on the sealing door, observation windows are evenly arranged on the sealing cover, and ventilation openings, LED light strips and humidifying nozzles are respectively provided on the top of the inner wall of the sealing cover.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model comprises a rotating center structure consisting of a rotating motor connected to a rotating bracket. Support plates and seedling pots are evenly distributed on the circumference of the rotating bracket. Driven by the rotating motor, the seedling pots can move circumferentially. At the same time, the support plates on which the seedling pots are installed are supported by support bars and guide rods. The connecting blocks fixed at the bottom of the support plates are connected to the removal screw. When the seedling pots that need to be turned over and fertilized move to one side of the closed door with the rotating bracket, the screw motor drives the removal screw to rotate. During the process, the support plates and seedling pots will move outward of the rotating bracket through the connecting blocks, removing the seedling pots from the closed space of the device, thus improving the convenience of daily operations such as turning over and fertilizing.

[0013] 2. This utility model uses a mounting ring at the bottom of the gear ring to support the lifting cylinder. Two sets of sensing units for detecting environmental data are mounted on a long, strip-shaped adjusting plate at the output end of the lifting cylinder. The movement of the adjusting plate, driven by the lifting cylinder, allows the sensing units to cover the entire longitudinal position. Simultaneously, as the adjusting motor drives the gears to rotate, the meshing between the gears and the gear ring causes the gear ring to rotate, adjusting the horizontal monitoring position of the sensing units. This expands the effective monitoring range of the sensing units, allowing for a more accurate understanding of the internal environmental conditions of the device and providing strong data support for precise temperature and humidity control.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] Please see Figures 1-5A rice seedling raising device with heat preservation and moisture retention functions includes a bottom shell 1, a rotary motor 2 installed in the bottom shell 1, and a rotary support 3 fixedly connected to the output end of the rotary motor 2. The rotary motor 2 is an 80ST-M04030 three-phase hybrid stepper motor. A removal mechanism 4 is provided on the rotary support 3, and seedling pots 5 are installed on the removal mechanism 4. A sealing cover 6 is provided on the top of the bottom shell 1, and an adjustment mechanism 7 is provided in the sealing cover 6. A sliding rail is symmetrically arranged on one side of the sealing cover 6, and a sealing door 8 is slidably connected to the sliding rail. A handle is provided on the sealing door 8. During the breeding process, the sealing door 8 is pulled down to fit against the bottom shell 1 to completely seal the sealing cover 6. Before breeding, fertilization, and other operations, the sealing door 8 is opened, and then the corresponding seedling pots 5 are removed in conjunction with the removal mechanism 4. The sealing door 8 is pulled down and attached to the removal mechanism 4 to seal the sealing cover 6, which can prevent external air from rushing into the sealing cover 6 during the breeding and fertilization operation and affecting the humidity and temperature inside the sealing cover 6. The sealing cover 6 is evenly equipped with observation windows for observing the breeding situation inside. The top of the inner wall of the sealing cover 6 is equipped with ventilation openings 9, LED light strips 10 and humidifying nozzles 11. The ventilation openings 9 are symmetrically distributed on the top of the inner wall of the sealing cover 6. The ventilation openings 9 are connected to external temperature control equipment to regulate the temperature inside the device during the seedling process. The LED light strips 10 are installed on the top of the inner wall of the sealing cover 6 to provide important light intensity for the plants during the breeding process. The humidifying nozzles 11 are installed at the top center of the inner space of the sealing cover 6 to regulate the humidity of the breeding environment during the breeding process.

[0023] The removal mechanism 4 includes support bars 41 evenly distributed on the rotating bracket 3. A support plate 42 is slidably connected to the support bars 41. The support bars 41 have a dovetail-shaped structure that corresponds to the dovetail-shaped grooves on the support plate 42, which prevents slippage. Seedling pots 5 are installed on the support plate 42. Rice is planted in the seedling pots 5 during the operation of the device. The grooves on the bottom of the seedling pots 5 correspond to the protrusions on the support plate 42, preventing the position of the seedling pots 5 from shaking or tilting during the rotation of the rotating bracket 3. This ensures that the six sets of seedling pots 5 maintain a certain distance, avoiding excessive spacing that could affect the normal growth of the rice. A support plate 42 is slidably connected to... Guide rod 43 is fixed on the rotating bracket 3. A connecting block 44 is fixed at the bottom of the support plate 42. The connecting block 44 is connected to the lead screw 45 by an internally embedded ball nut. The lead screw 45 is rotatably connected to the bottom of the rotating bracket 3 and is fixedly connected to the output end of the lead screw motor 46. The axial direction of the guide rod 43 is consistent with the axial direction of the lead screw 45 to avoid interference with the movement of the support plate 42 and improve the stability of the support plate 42 when it moves. The lead screw motor 46 is fixed on the rotating bracket 3. The lead screw motor 46 is a 57HS09 two-phase hybrid stepper motor.

[0024] The adjustment mechanism 7 includes a gear ring 71 rotatably connected in the enclosed cover 6. The gear ring 71 meshes with a gear, and the gear is fixed to the output end of the adjustment motor 72. The adjustment motor 72 is fixed to the top of the enclosed cover 6. The adjustment motor 72 is a 28BYJ-48 DC geared stepper motor. A bushing is provided at the connection between the output end of the adjustment motor 72 and the enclosed cover 6. A mounting ring 73 is fixed to the bottom of the gear ring 71, and mounting brackets are evenly arranged at the bottom of the mounting ring 73. A lifting cylinder 74 is fixed in the mounting bracket. An adjustment plate 75 is fixedly connected to the output end of the lifting cylinder 74, and sensing units are symmetrically installed on the adjustment plate 75. The lifting cylinder 74 is selected according to the actual situation. During the process of the adjustment motor 72 driving the gear to rotate, the gear ring 71 can be rotated by the meshing of the gear and the gear ring 71. The adjustment plate 75 has a long strip structure, and two sets of sensing units are arranged, respectively arranged on one side of the top of the adjustment plate 75. The top and bottom of the device include a sensing unit comprising a temperature sensor, a humidity sensor, and a gas concentration sensor. Mounting brackets are evenly distributed around the bottom of the mounting ring 73, allowing multiple sets of temperature, humidity, and gas concentration sensors to be distributed throughout the entire seedling space. This enables real-time monitoring of the internal temperature, humidity, and gas concentration data. Two sensing units on each set are located at the top and bottom of the elongated adjustment plate 75, respectively. As the lifting cylinder 74 moves the adjustment plate 75 up and down, the sensing unit's detection range can cover the entire longitudinal space. The temperature, humidity, and gas concentration sensors are connected to an external controller. After collecting internal temperature, humidity, and gas concentration data, they synchronously regulate the internal environment through the ventilation vent 9, LED light strip 10, and humidifying nozzle 11. Simultaneously, the controller connects to the rotary motor 2, lead screw motor 46, adjustment motor 72, and lifting cylinder 74 to achieve coordinated operation of the device.

[0025] It should be noted that this rice seedling raising device with heat preservation and moisture retention functions is used by first planting rice in seedling trays 5, and then installing the seedling trays 5 on the corresponding support plates 42. The device consists of a rotating motor 2 connected to a rotating bracket 3, forming the rotating center structure of the device. The support plates 42 and seedling trays 5 are evenly distributed on the circumference of the rotating bracket 3. Driven by the rotating motor 2, the seedling trays 5 can be moved circumferentially. When the seedling trays 5 that need to be turned over and fertilized move to one side of the closed door 8, the screw motor 46 drives the moving screw 45 to rotate. During this process, the support plates 42 and seedling trays 5 will move outward of the rotating bracket 3 through the connecting block 44, removing the seedling trays 5 from the closed space of the device. After turning over the soil, the screw motor 46 rotates in the opposite direction, driving the support plates 42 and seedling trays 5 outward of the rotating bracket 3. 42 and seedling tray 5 return to the internal space of the device, and finally pull down the closing door 8 to completely seal the internal space; the lifting cylinder 74 drives the adjustment plate 75 to move, which can adjust the longitudinal position of the sensing unit. At the same time, during the process of the adjustment motor 72 driving the gear to rotate, the gear and the gear ring 71 can be meshed to drive the gear ring 71 to rotate, adjusting the monitoring position of the sensing unit in the horizontal direction, expanding the effective monitoring range of the sensing unit, and more accurately grasping the environmental conditions inside the device, providing strong data support for the precise adjustment of temperature and humidity. After the sensing unit detects the environmental data, it feeds it back to the environmental control equipment through the controller. The vent 9 connects to the external temperature control equipment to regulate the temperature inside the device during the seedling process. Combined with the humidifying nozzle 11, it adjusts the humidity of the internal space, achieving the actual effect of heat preservation and moisture retention.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
