Description

Technical Field

[0001] This invention relates to the field of rice cultivation equipment, and more particularly to a constant temperature cultivation device for a dual-purpose nuclear male sterile line. Background Technology

[0002] Two-line hybrid rice is an important type of rice production in my country, playing a vital role in ensuring food security. Photoperiod- and temperature-sensitive dual-purpose nuclear male-sterile lines are the foundation of two-line hybrid rice. The photoperiod- and temperature-sensitive fertility conversion characteristics of these lines are crucial for their production and application. Due to their photoperiod- and temperature-sensitive fertility conversion characteristics (long-day, high-temperature sterility, short-day, low-temperature seed setting), the safety of two-line hybrid rice seed production is easily affected by abnormally low temperatures and insufficient sunlight (leading to self-pollination of the male-sterile lines, resulting in mixed male-sterile seeds after harvest, severely impacting the purity of the two-line hybrid rice seeds).

[0003] A Chinese patent with publication number CN115997520B discloses an automated constant-temperature rice seed cultivation device. In this invention, during the germination period of rice seeds, the cultivation tray is not in the liquid storage tank. The liquid in the liquid storage tank can be sprayed onto the cultivation tray through a spraying device, thereby ensuring the soil moisture during the germination period.

[0004] However, the above technical solutions still have the following shortcomings: before sowing rice seeds, the soil in the cultivation tray cannot be loosened, which is not conducive to improving soil permeability, nor is it conducive to the soil retaining moisture and oxygen.

[0013] Preferably, the anti-collision assembly further includes: two second telescopic rods, one end of which is fixedly connected to the mounting base and the other end of which is fixedly connected to the movable plate; and two springs, which are respectively sleeved on the two second telescopic rods.

[0014] Preferably, the soil-turning assembly includes: a vertical rod, the upper end of which is rotatably connected to the bottom surface of the mounting base; a horizontal plate, which is fixedly connected to the lower end of the vertical rod; a plurality of rakes, all mounted on the bottom surface of the horizontal plate; and a gear, which is fixedly sleeved on the vertical rod and matches the rack.

Detailed Implementation

[0031] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0032] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a constant temperature cultivation device for a dual-purpose nuclear sterile line includes a box 100, a temperature regulating component 130, a cultivation tray 200, and a soil turning mechanism 300.

[0035] The front of the chamber 100 is hinged with two doors 101. A temperature control element 130 is installed on the inner top surface of the chamber 100 to regulate the temperature inside the chamber 100. The temperature control element 130 is existing technology, and its specific structure and working principle will not be described in detail here. The incubation tray 200 is located inside the chamber 100, and two slots 201 are provided on the bottom surface of the incubation tray 200.

[0036] The soil turning mechanism 300 includes a lead screw 301, a lead screw nut 302, an anti-collision component 310, a soil turning component 320, a rack 330, and a motor 340.

[0037] A lead screw 301 is rotatably mounted inside the housing 100; a lead screw nut 302 is sleeved on the lead screw 301; an anti-collision component 310 is sleeved on the lead screw nut 302, and the anti-collision component 310 is used to prevent the lead screw nut 302 from colliding with the inner wall of the housing 100; a soil turning component 320 is mounted on the anti-collision component 310, and the soil turning component 320 is used to turn the soil in the cultivation tray 200; a rack 330 is mounted inside the housing 100, and the rack 330 is used to rotate the soil turning component 320; a motor 340 is mounted on one side of the housing 100, and the power output shaft of the motor 340 is connected to one end of the lead screw 301. The motor 340 is a reversible motor and can rotate in either direction.

[0038] Specifically, by starting the motor 340, the power output shaft of the motor 340 drives the soil-turning component 320 to move via the lead screw 301, lead screw nut 302, and anti-collision component 310. This causes the soil-turning component 320 to turn the soil in the cultivation tray 200, thereby loosening the soil, enhancing its aeration, and helping it retain moisture and oxygen, creating favorable conditions for rice growth. Furthermore, as the soil-turning component 320 moves, it rotates under the influence of the rack 330, further turning the soil in the cultivation tray 200. The temperature control component 130 can regulate the temperature inside the chamber 100, or maintain a constant temperature within the chamber 100.

[0039] like Figure 3 and Figure 4As shown, the constant temperature cultivation device for dual-use nuclear sterile lines also includes a support mechanism 120, which includes a threaded cylinder 121, a threaded rod 122, four first telescopic rods 124, and a support plate 125.

[0040] The threaded cylinder 121 is rotatably connected to the inner bottom surface of the housing 100, and a rotating rod 123 is installed on the threaded cylinder 121. The threaded rod 122 is threadedly connected to the threaded cylinder 121; the support plate 125 is fixedly connected to the upper end of the threaded rod 122, and the top of the support plate 125 is provided with two protrusions that match the slot 201. The lower ends of the four first telescopic rods 124 are all fixedly connected to the inner bottom surface of the housing 100, and the upper ends of the four first telescopic rods 124 are all fixedly connected to the bottom surface of the support plate 125.

[0041] Specifically, when the rotating rod 123 is rotated, the threaded cylinder 121 will rotate, which will cause the threaded rod 122 to move, which in turn will cause the tray 125 to move, thereby adjusting the height of the seedling tray, making it easier to remove the seedling tray from the box 100.

[0042] like Figure 1 , Figure 2 and Figure 7 As shown, the constant temperature cultivation device for dual-use nuclear sterile lines also includes a drain pipe 102, a sealing cover 103, and a water spraying mechanism 140.

[0043] A drain pipe 102 is installed on one side of the housing 100; a sealing cap 103 is connected to the end of the drain pipe 102 located outside the housing 100; the water spraying mechanism 140 includes a water pump 141, a hollow pipe 142, and multiple nozzles 143. The water pump 141 is installed on one side of the housing 100; the hollow pipe 142 is installed on the inner wall of the housing 100, and the hollow pipe 142 is connected to the water outlet pipe of the water pump 141; multiple nozzles 143 are equidistantly installed on the hollow pipe 142.

[0044] Specifically, by connecting the water pump 141's suction pipe to an external water supply pipe, and then starting the water pump 141, water is transported into the hollow pipe 142, and then sprayed out through multiple nozzles 143. The sprayed water falls into the cultivation tray 200. When the water in the cultivation tray 200 falls to the bottom of the box 100, the sealing cover 103 can be separated from the drain pipe 102, thereby facilitating the drainage of the water at the bottom of the box 100 through the drain pipe 102.

[0045] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the isothermal cultivation device for dual-purpose nuclear sterile lines also includes an air inlet valve 104 and a gas reflux mechanism 110.

[0046] The intake valve 104 is installed on one side of the housing 100; the gas return mechanism 110 includes a cover 111, a hollow seat 112, an exhaust pipe 113 and a return pipe 114.

[0047] The cover 111 is fixedly installed on one side of the box 100, and the inside of the cover 111 is connected to the inside of the box 100; the hollow seat 112 is fixedly connected to the end of the cover 111 located outside the box 100; the exhaust pipe 113 is installed on the hollow seat 112; one end of the return pipe 114 is connected to the hollow seat 112, and the other end of the return pipe 114 is fixedly connected to and connected to the box 100; valves are installed on both the exhaust pipe 113 and the return pipe 114.

[0048] Specifically, when it is necessary to increase the temperature inside the chamber 100, the blower can be started, the valve on the return pipe 114 can be opened and the valve on the exhaust pipe 113 can be closed, so that the air inside the chamber 100 returns to the chamber 100 after passing through the cover 111 and the return pipe 114, thereby facilitating air flow and ensuring uniform heating of the air inside the chamber 100.

[0049] like Figure 2 , Figure 5 , Figure 6 , Figures 8-10 As shown, the soil turning mechanism 300 also includes a limiting groove 303, a guide rod 304, and multiple fan blades 305.

[0050] The limiting groove 303 is formed on the outer surface of the lead screw nut 302; the guide rod 304 is installed inside the housing 100; the multiple fan blades 305 are located inside the cover 111, and the multiple fan blades 305 are equidistantly installed on the lead screw 301.

[0051] The anti-collision assembly 310 includes a mounting base 311, a guide tube 312, a movable plate 313, an insert plate 314, a cylinder 315, a movable plate 318, two second telescopic rods 316, two springs 317, and a guide groove 319.

[0052] Mounting base 311 is rotatably sleeved on lead screw nut 302; guide tube 312 is slidably sleeved on guide rod 304, and guide tube 312 is fixedly connected to mounting base 311; movable plate 313 is set inside mounting base 311; insert plate 314 is fixedly connected to the bottom surface of movable plate 313, and insert plate 314 is inserted into limiting groove 303; cylinder 315 is installed on one side of movable plate 313; moving plate 318 is slidably connected to mounting base 311, the length of moving plate 318 is greater than the length of mounting base 311, guide groove 319 is set in a "V" shape, guide groove 319 is opened through moving plate 318, and cylinder 315 is located inside guide groove 319 and slidably connected to guide groove 319.

[0053] One end of each of the two second telescopic rods 316 is fixedly connected to the mounting base 311, and the other end of each of the two second telescopic rods 316 is fixedly connected to the movable plate 318; two springs 317 are respectively sleeved on the two second telescopic rods 316.

[0054] Specifically, when the motor 340 drives the lead screw 301 to rotate, the lead screw nut 302 will move to one side of the housing 100. Since the length of the moving plate 318 is greater than the length of the mounting base 311, one end of the moving plate 318 will first abut against the inner wall of the housing 100, thereby causing the moving plate 318 to move. The guide groove 319 on the moving plate 318 will push the cylinder 315 to move upward, thereby causing the movable plate 313 and the insert plate 314 to move upward, thereby compressing the second telescopic rod 316 and the second spring 317, thereby causing the insert plate 314 to separate from the limiting groove 303 on the lead screw nut 302. This causes the lead screw nut 302 to lose its restraint, allowing it to rotate along with the lead screw 301, thus preventing it from colliding with the inner wall of the housing 100. If the lead screw 301 moves in the opposite direction, the rebound force of the second spring 317 will push the movable plate 313, the insert plate 314, and the cylinder 315 downwards, thereby pushing the movable plate 318 and the guide groove 319 to reset. As the lead screw nut 302 rotates, the insert plate 314 will engage with the limiting groove 303 on the lead screw nut 302. At this time, the lead screw nut 302 will move horizontally due to the rotation of the lead screw 301.

[0055] like Figure 8 As shown, the soil turning assembly 320 includes a vertical rod 321, a horizontal plate 322, multiple rakes 323, and a gear 324. The upper end of the vertical rod 321 is rotatably connected to the bottom surface of the mounting base 311; the horizontal plate 322 is fixedly connected to the lower end of the vertical rod 321; multiple rakes 323 are all installed on the bottom surface of the horizontal plate 322; the gear 324 is fixedly sleeved on the vertical rod 321, and the gear 324 matches the rack 330. The rack 330 has teeth in the middle, and the number of teeth on the rack 330 is three times the number of teeth on the gear 324.

[0056] Specifically, when the mounting base 311 moves the vertical rod 321, the horizontal plate 322 and the rake rod 323 also move. The moving rake rod 323 will turn over the soil in the cultivation tray 200. When the gear 324 on the vertical rod 321 meshes with the teeth on the rack 330, if the vertical rod 321 is moved again, the vertical rod 321 will rotate, which will cause the horizontal plate 322 and the rake rod 323 to rotate. This will cause the rake rod 323 to turn over the soil in the cultivation tray 200 while rotating, which can turn the soil more evenly and make the soil looser.

[0057] Working principle: In actual use, the soil-filled cultivation tray 200 is placed on the support plate 125, so that the protrusions on the support plate 125 are inserted into the slots 201 at the bottom of the cultivation tray 200. Then, by rotating the rotating rod 123, the threaded cylinder 121 is rotated, which in turn causes the threaded rod 122 to move the support plate 125 upward, thereby bringing the soil in the cultivation tray 200 into contact with the rake rod 323.

[0058] Then, by starting the motor 340, the power output shaft of the motor 340 drives the lead screw 301 to rotate alternately clockwise and counterclockwise. When the lead screw 301 rotates, the lead screw nut 302 and the mounting base 311 will move, which in turn drives the vertical rod 321 to move, which in turn causes the horizontal plate 322 and the rake rod 323 to move. The moving rake rod 323 will turn over the soil in the cultivation tray 200. When the gear 324 on the vertical rod 321 meshes with the teeth on the rack 330, if the vertical rod 321 is moved at this time, the vertical rod 321 will rotate, which in turn causes the horizontal plate 322 and the rake rod 323 to rotate. This causes the rake rod 323 to turn over the soil in the cultivation tray 200 while rotating, which can turn the soil more evenly and make the soil looser.

[0059] After the soil is loosened, rice seeds are placed in the soil of the cultivation tray 200, then the box door 101 is closed, the water pump 141 is connected to the external water supply pipe, and the water pump 141 is started to deliver water into the hollow tube 142, and then the water is sprayed out through multiple nozzles 143. The sprayed water will fall into the cultivation tray 200.

[0060] Then, by activating the temperature control unit 130, the interior of the chamber 100 is heated. At the same time, the valve on the return pipe 114 is opened and the valve on the exhaust pipe 113 is closed. Then, by activating the motor 340, the motor 340 drives the lead screw 301 to rotate, which in turn drives the multiple fan blades 305 to rotate, which in turn blows out air. After passing through the cover 111 and the return pipe 114, the air returns to the chamber 100, thereby accelerating the airflow inside the chamber 100 and making it easier for the air inside the chamber 100 to be heated evenly. When the motor 340 drives the lead screw 301 to rotate, the lead screw nut 302 will move to one side of the housing 100. Since the length of the moving plate 318 is greater than the length of the mounting base 311, one end of the moving plate 318 will first abut against the inner wall of the housing 100, thereby causing the moving plate 318 to move. The guide groove 319 on the moving plate 318 will push the cylinder 315 to move upward, thereby causing the movable plate 313 and the insert plate 314 to move upward, thereby compressing the second telescopic rod 316 and the second spring 317, thereby causing the insert plate 314 to separate from the limiting groove 303 on the lead screw nut 302, thereby freeing the lead screw nut 302 from restriction, allowing the lead screw nut 302 to rotate with the rotation of the lead screw 301, thereby preventing the lead screw nut 302 from colliding with the inner wall of the housing 100.

[0061] When the temperature inside the chamber 100 reaches the preset value, the motor 340 is turned off, and the temperature regulating element 130 keeps the preset temperature inside the chamber 100, which facilitates the germination of rice seeds.

[0062] When the humidity inside the chamber 100 is high, the valve on the return pipe 114 can be closed and the valve on the exhaust pipe 113 can be opened. Then, by starting the motor 340, the motor 340 drives the lead screw 301 to rotate, which in turn drives the multiple fan blades 305 to rotate, which in turn blows out air. The air is then discharged outside the chamber 100 through the cover 111 and the exhaust pipe 113, allowing outside air to enter the chamber 100 through the air inlet valve 104, thereby accelerating the airflow inside and outside the chamber 100 and facilitating the reduction of humidity inside the chamber 100.

[0063] In summary, the beneficial effects of the present invention include at least the following:

[0064] 1. The soil-turning mechanism in this invention is equipped with a lead screw, lead screw nut, anti-collision component, soil-turning component, rack, and motor. By starting the motor, the lead screw, lead screw nut, and anti-collision component drive the soil-turning component to move, thereby turning the soil in the cultivation tray to loosen the soil, enhance soil permeability, and help the soil retain moisture and oxygen, creating favorable conditions for rice growth. Furthermore, when the soil-turning component moves, it will rotate under the influence of the rack, allowing the soil to be turned more evenly, making the soil looser and more conducive to rice growth.

[0065] 2. The gas reflux mechanism in this invention, by setting up a cover, a hollow seat and a reflux pipe, first starts the temperature regulating component when heating the inside of the chamber, and then starts the motor, so that the motor drives the lead screw to rotate, which in turn drives multiple fan blades to rotate, and then the multiple fan blades blow out air. After passing through the cover and the reflux pipe, the air returns to the chamber, thereby accelerating the air flow inside the chamber and facilitating uniform heating of the air inside the chamber.

[0066] 3. The anti-collision component in this invention comprises a mounting base, guide tube, movable plate, insert plate, cylinder, second telescopic rod, spring, and movable plate. When the motor drives the lead screw to rotate, the lead screw nut moves to one side of the housing. Since the length of the movable plate is greater than the length of the mounting base, one end of the movable plate will first abut against the inner wall of the housing. The guide groove on the movable plate will push the cylinder upward, thereby driving the movable plate and insert plate upward, which in turn causes the insert plate to separate from the limiting groove on the lead screw nut. This allows the lead screw nut to lose its restraint and rotate with the lead screw, thus preventing the lead screw nut from colliding with the inner wall of the housing.

[0067] Example 2

[0068] like Figure 4 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that the constant temperature cultivation device for the dual-purpose nuclear sterile line also includes two vertical tubes 202 and two moving tubes 204.

[0069] Both vertical tubes 202 are installed through the cultivation tray 200, and both vertical tubes 202 are provided with vertical grooves 203; two movable tubes 204 are respectively sleeved on the two vertical tubes 202, the movable tubes 204 are made of rubber, and the movable tubes 204 can slide along the vertical tubes 202.

[0070] Working principle: Before use, the area covered by the moving pipe 204 in the vertical groove 203 is adjusted by moving the moving pipe 204. During use, if the water level in the cultivation tray 200 exceeds the moving pipe 204, the water in the cultivation tray 200 will flow through the vertical groove 203 to the bottom of the cultivation tray 200.

[0071] Example 3

[0072] While all other parts are the same as in Example 1, the difference between this example and Example 1 is that the constant temperature cultivation device for the dual-purpose nuclear sterile line also includes a control system, which is used to control the operation of the motor 340; the control system includes a data acquisition module, a data analysis module and a control module.

[0073] The data acquisition module is used to collect the resistance value of the rake 323 and the power consumption value of the motor 340, and send the resistance value of the rake 323 and the power consumption value of the motor 340 to the data analysis module.

[0074] The data analysis module receives the resistance value of the rake 323 and the power consumption value of the motor 340 sent from the data acquisition module, and generates a soil looseness coefficient based on the values ​​sent by the data acquisition module, and then generates corresponding control commands based on the soil looseness coefficient.

[0075] The control module is used to control the motor 340 to continue running or stop running according to control commands.

[0076] The data analysis module generates control commands in the following way:

[0077] Step 1: Receive the user-defined soil looseness coefficient threshold and mark it as S1;

[0078] Step 2: Generate a soil looseness coefficient based on the values ​​sent by the data acquisition module and label it as S;

[0079] Step 3: Compare the soil softness coefficient with the soil softness coefficient threshold; if S > S1, it means the soil is relatively soft, and the data analysis module generates a control command to shut down the motor 340; if the soil softness coefficient S ≤ S1, it means the soil is relatively hard, and the data analysis module generates a control command to continue running the motor 340.

[0080] The soil looseness coefficient is generated as follows:

[0081]

[0082] In the formula, S is the soil looseness coefficient. The higher the value of S, the looser the soil; the lower the value of S, the harder the soil. F is the resistance value of the rake 323. P is the power consumption value of the motor 340. x and y are integral variables. and The effects of resistance and power consumption on soil looseness are represented respectively: It is a normalization term used to limit the range of the evaluation function to a reasonable range; α and β are weighting factors that adjust the influence of resistance and power consumption, and their specific values ​​can be selected as normal numbers according to the actual situation.

[0083] By setting up a control system, the soil softness can be assessed in real time, and the operation of motor 340 can be controlled more effectively. When the soil is soft, motor 340 can be turned off in time to avoid unnecessary power consumption. When the soil is hard, motor 340 can continue to run, and the rake 323 can continue to turn the soil to ensure that the soil reaches the preset softness, which is conducive to the growth of rice.
