Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a seed germination experimental device for agricultural technology research. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of agricultural labor are living plants and animals, and the products obtained are the plants and animals themselves. Agriculture is a basic industry that provides support for national economic construction and development. Agricultural technology mainly refers to the science and technology used in agricultural production, as well as some simple agricultural product processing technologies specifically for rural and urban life, including planting, breeding, the use of chemical fertilizers and pesticides, the identification of various production materials, and efficient agricultural production models.

[0003] In agricultural technology research, seed germination experiments are often required. To improve the germination rate and shorten the germination time, seed germination stirring rods are used. However, existing stirring rods are generally fixed inside the germination tank, making cleaning inconvenient. After prolonged use, bacteria can easily grow on the stirring rods, reducing the seed germination rate and significantly affecting the experimental results. Furthermore, their complex structure makes maintenance difficult, reducing the practicality of the device. Moreover, the existing stirring process is relatively simple and inefficient. Additionally, the germination process requires specific temperatures, and existing germination equipment does not accurately control the temperature, which also affects the germination rate. Utility Model Content

[0004] In view of the above situation and to overcome the existing defects, this utility model provides a seed germination experimental device for agricultural technology research.

[0005] This utility model provides the following technical solution: An experimental device for seed germination in agricultural technology research, comprising a germination tank, which is a hollow structure with an open top. A detachable cover is provided on the germination tank, and a support frame is provided on the cover. A stirring assembly is provided on the support frame, and a temperature adjustment assembly is provided on the stirring assembly. Fixing members are evenly distributed on the upper side of the germination tank. The stirring assembly includes a drive motor, which is mounted on the support frame. A connecting block is connected to the output end of the drive motor. A connecting rod is evenly distributed below the connecting block, passing through the cover and positioned below it. A rotating rod is provided below the connecting rod, and fixing plates are evenly distributed at the upper and lower ends of the rotating rod. A stirring structure is provided on the fixing plate, and the other end of the stirring structure is located at the upper end of the rotating rod.

[0006] Furthermore, the stirring structure includes a bearing seat located on the opposite side of the fixed plate. A lead screw is installed inside the bearing seat, and lead screw pairs are evenly fitted onto the lead screw. Stirring rods are evenly fitted onto the lead screw pairs. A drive wheel is fitted onto the upper end of the rotating rod, and a connecting wheel is fitted onto the upper end of the lead screw. The connecting wheel meshes with the drive wheel. During stirring, the drive motor is activated, and the drive motor drives the rotating rod to rotate via a connecting block and a connecting rod. The rotating rod drives the stirring structure to rotate laterally via the fixed plate, thus stirring the seeds in the germination tank laterally. Simultaneously, the rotating rod drives the drive wheel to rotate, the drive wheel drives the connecting wheel to rotate, and the connecting wheel drives the lead screw to rotate. As is known in the prior art, the lead screw moves up and down along the lead screw pairs during rotation, and the lead screw pairs move up and down along the stirring rods, thereby achieving a longitudinal stirring process for the seeds.

[0007] The temperature adjustment component includes an air chamber located within a rotating rod. A heating device is located at the lower end of the air chamber. A movable plate is movably mounted at the upper end of the air chamber, and a movable rod is mounted on the movable plate. One end of the movable rod, away from the movable plate, movably passes through a cover plate and is positioned below a connecting block. A magnetic plate is mounted on the movable rod, and a spring is fitted onto the movable rod and mounted on the cover plate. Electrically energized coils are evenly distributed within the connecting block. Exhaust ports are evenly distributed on the rotating rod and connected to the air chamber. A one-way valve is located within the air chamber. A balance port is symmetrically arranged on the movable plate, and a second one-way valve is located within the balance port. When the temperature inside the germination tank is low, the heating device is energized to raise the temperature inside the air chamber. When the energized coil is powered on, a magnetic field is generated around it, which exerts a repulsive force on the magnetic plate, causing the magnetic plate to move downwards along the moving rod. At this time, the spring is in a compressed state. As the moving rod moves downwards, it carries the moving plate down along the air chamber. The pressure below the moving plate in the air chamber increases, and hot gas is discharged into the germination tank through the exhaust port and one-way valve (which controls the gas to only exit from the air chamber) to heat the seeds. When heating is no longer needed, the heating equipment is powered off, and the energized coil is also powered off. The magnetic plate loses its repulsive force and moves upwards under the elastic force of the spring. At this time, the gas balances the pressure below the moving plate in the air chamber through the balance port and one-way valve (which controls the gas to only enter the air chamber from the outside), preparing it for the next heating.

[0008] Preferably, the fixing component includes a support plate, which is evenly distributed on the upper part of the outer wall of the germination tank. The support plate has a threaded hole, and a threaded rod is movably disposed in the threaded hole. The threaded rod passes through the threaded hole and is provided with a pressure plate. The pressure plate is located above the cover plate. When it is necessary to clean the stirring structure and the rotating rod, the threaded rod is rotated, and the threaded rod lifts the pressure plate, loosening the cover plate. The cover plate separates from the stirring assembly, which facilitates the cleaning of the stirring assembly. At the same time, it is also convenient to clean the germination tank after the seeds are removed from the germination tank.

[0009] Furthermore, the support frame is provided with a protective tube, and the drive motor is located inside the protective tube, which protects the drive motor.

[0010] The germination tank is equipped with a temperature detector detachably mounted on the upper part of its inner wall, and a control panel is located under the support frame. The temperature detector is used to monitor the temperature inside the germination tank, and then the control panel sends instructions to each device, making the overall equipment operation more accurate and more mechanized.

[0011] The seed germination experimental device for agricultural technology research proposed by this utility model, which adopts the above structure, has the following beneficial effects:

[0012] 1. By setting up the stirring components, not only can horizontal stirring be achieved, but also vertical stirring can be carried out simultaneously, so that the seeds are heated more evenly, thereby improving the germination rate of the seeds.

[0013] 2. The temperature adjustment component, together with the temperature detector and control panel, monitors and controls the temperature of the seeds during the germination process, keeping the seeds at a suitable germination temperature to further improve the germination rate.

[0014] 3. Due to the setting of the fixing parts, it is easy to separate the cover plate and the stirring component from the germination tank, which makes it easy to clean the stirring component. At the same time, it is also convenient to clean the germination tank after the seeds are removed.

[0015] 4. The temperature inside the germination tank is monitored using a temperature detector, and then instructions are sent to each device through the control panel, making the overall equipment operation more accurate and the degree of mechanization higher. Attached Figure Description

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a seed germination experimental device for agricultural technology research, including a germination tank 1, which is a hollow structure with an open top. A cover plate 2 is detachably provided on the germination tank 1, a support frame 3 is provided on the cover plate 2, a stirring assembly 4 is provided on the support frame 3, a temperature adjustment assembly 5 is provided on the stirring assembly 4, and fixing parts 6 are evenly provided on the upper side of the germination tank 1.

A rotating rod 10 is provided below the connecting rod 9, and a fixing plate 11 is evenly provided at the upper and lower ends of the rotating rod 10. A stirring structure 12 is provided on the fixing plate 11, and the other end of the stirring structure 12 is located at the upper end of the rotating rod 10.

[0025] like Figure 1 As shown, the stirring structure 12 includes a bearing seat 13, which is located on the opposite side of the fixed plate 11. A lead screw 14 is provided inside the bearing seat 13. Lead screw pairs 15 are evenly fitted on the lead screw 14. Stirring rods 16 are evenly provided on the lead screw pairs 15. A drive wheel 17 is fitted on the upper end of the rotating rod 10. A connecting wheel 18 is fitted on the upper end of the lead screw 14. The connecting wheel 18 meshes with the drive wheel 17.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the temperature adjustment component 5 includes an air chamber 19, which is located inside the rotating rod 10. A heating device 31 is provided at the lower end of the air chamber 19. A movable plate 20 is provided at the upper end of the air chamber 19. A movable rod 21 is provided on the movable plate 20. The end of the movable rod 21 away from the movable plate 20 can be moved through the cover plate 2 and is located below the connecting block 8. A magnetic plate 22 is provided on the movable rod 21. A spring 32 is sleeved on the movable rod 21 and is located on the cover plate 2. A energized coil 23 is evenly arranged inside the connecting block 8. An exhaust port 24 is evenly arranged on the rotating rod 10 and is connected to the air chamber 19. A one-way valve 25 is provided inside the air chamber 19. A balance port 26 is symmetrically arranged on the movable plate 20, and a two-way valve 27 is provided inside the balance port 26.

[0027] like Figure 1 , Figure 4 As shown, the fixing member 6 includes a support plate 33, which is evenly distributed on the upper part of the outer wall of the germination tank 1. The support plate 33 is provided with a threaded hole 34, and a threaded rod 35 is movably provided in the threaded hole 34. The threaded rod 35 passes through the threaded hole 34, and a pressure plate 36 is provided on the threaded rod 35. The pressure plate 36 is located above the cover plate 2.

[0028] In practical use, during the stirring process, the drive motor 7 is started. The drive motor 7 drives the rotating rod 10 to rotate through the connecting block 8 and the connecting rod 9. The rotating rod 10 drives the stirring structure 12 to rotate laterally through the fixed plate 11, thus stirring the seeds in the germination tank 1 laterally. At the same time, the rotating rod 10 drives the drive wheel 17 to rotate, the drive wheel 17 drives the connecting wheel 18 to rotate, and the connecting wheel 18 drives the lead screw 14 to rotate. As is known from the prior art, the lead screw 14 drives the lead screw pair 15 to move up and down during rotation. The lead screw pair 15 drives the stirring rod 16 to move up and down, thereby realizing the vertical stirring process of the seeds. When the temperature detector 29 detects that the temperature inside the germination tank 1 is low, the control panel 30 issues a command to power the heating device 31, raising the temperature inside the air chamber 19. Then, the energizing coil 23 is energized. A magnetic field is generated around the coil 23, which generates a repulsive force on the magnetic plate 22, causing the magnetic plate 22 to move downward along the moving rod 21. At this time, the spring 32 is in a compressed state. As the moving rod 21 moves downward, it carries the moving plate 20 downward along the air chamber 19. The pressure below the moving plate 20 in the air chamber 19 increases. Hot gas is discharged into the germination tank 1 through the exhaust port 24 and the one-way valve 25 (which controls the gas to be discharged only from the air chamber 19) to heat the seeds. When heating is no longer needed, the heating device 31 is de-energized, and the energized coil 23 is de-energized. The magnetic plate 22 loses its repulsive force and moves upward under the elastic force of the spring. At this time, the gas balances the pressure below the moving plate 20 in the air chamber 19 through the balance port 26 and the one-way valve 27 (which controls the gas to be discharged only from the outside into the air chamber 19), in preparation for the next heating.
