[0002] A seed drought resistance testing device, disclosed in CN211240754U, includes a support base and a testing box fixed on the support base. Several petri dishes are placed inside the box. The testing box includes a cover with an illumination light source at its center and a rotating device at its bottom. The rotating device includes a frustum, a turntable evenly distributed around the frustum, and a motor connected to the turntable. The petri dishes are placed on the turntable. In this seed drought resistance testing device, each petri dish is individually placed on the turntable. The rotation of the turntable ensures more sufficient and uniform light exposure in the petri dishes, guaranteeing that each petri dish receives the same amount of light, reducing experimental errors. The turntable arrangement also ensures that each petri dish is not obstructed, facilitating observation.

[0003] In existing technologies, multiple motors are used to rotate the culture dish on the turntable. While this design can provide better light uniformity, it is more complex to operate due to the need for precise synchronization between multiple motors, which increases the cost and maintenance difficulty of the device.

[0004] Therefore, we propose a device for detecting the drought resistance of wheat seeds. Summary of the Invention

[0005] The purpose of this invention is to provide a device for detecting the drought resistance of wheat seeds, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a device for detecting the drought resistance of wheat seeds, comprising a detection chamber, wherein a spotlight and a turntable are provided inside the detection chamber, and a petri dish is provided on the turntable, and the spotlight is used to irradiate the seeds in the petri dish.

[0007] It also includes a rotating plate that presses against the petri dish. The rotating plate has a movable groove in the middle. A rotating rod that passes through the movable groove is rotatably connected inside the detection box. An insert plate and an elastic element are movably connected to the outer surface of the rotating rod. The insert plate is inserted into the rotating plate. A pressing plate that passes through the rotating plate is also pressed against the outer surface of the rotating rod. The pressing plate is in contact with the petri dish.

[0008] The top of the turntable has an installation groove, and the culture dish rotates within the installation groove via a limiting member.

[0009] Preferably, a motor is fixedly connected to the outside of the detection box, the output shaft of the motor passes through the detection box and is fixedly connected to the rotating rod, and the center of the bottom surface of the turntable is rotatably connected to the detection box.

[0010] Preferably, there are two spotlights, one of which is located above the center of the turntable, and a fixed plate is fixedly connected inside the detection box. The other spotlight is located on the fixed plate, and the rotating rod is rotatably connected to the fixed plate.

[0011] Preferably, a limiting chassis is fixedly connected to the bottom of the rotating rod, and the diameter of the limiting chassis is larger than the inner diameter of the movable groove.

[0012] Preferably, the insert plate is horizontally inserted into the rotating plate, and a spring is connected between the rotating plate and the insert plate. The rotating plate has a rotating groove, and a connecting column is fixedly connected to the end of the rotating groove and the outer surface of the rotating rod. A movable ball is movably embedded on the connecting column, and the insert plate is connected to one of the movable balls. The other two movable balls are connected and engaged by elastic elements.

[0013] Preferably, the pressure plate has a T-shaped structure, the end of the pressure plate has a magnetic attraction structure, and the part of the self-rotating rod corresponding to the pressure plate has a magnetic structure that magnetically engages with the pressure plate.

[0014] Preferably, the limiting component includes an arc-shaped plate that is connected and fixed to the bottom edge of the culture dish and rotates within the mounting groove. Arc-shaped rods are slidably fitted at both ends of the arc-shaped plate, and sliders are fixedly connected to the ends of the arc-shaped rods.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-12 The present invention provides a device for detecting the drought resistance of wheat seeds, including a detection box 1, wherein a spotlight 2 and a turntable 3 are provided inside the detection box 1, and a petri dish 4 is provided on the turntable 3. The spotlight 2 is used to irradiate the seeds in the petri dish 4.

[0034] This application uses light to germinate wheat seeds in a petri dish 4, thereby detecting the germination ability of the seeds. The rotating disk 3 is used to move the position of the petri dish 4, so as to make the light exposure more comprehensive.

[0035] The turntable 3 has a mounting groove 11 at its top. The petri dish 4 rotates within the mounting groove 11 via a limiting member. The limiting member includes an arc-shaped plate 19 that is connected and fixed to the bottom edge of the petri dish 4 and rotates within the mounting groove 11. Arc-shaped rods 20 are slidably fitted at both ends of the arc-shaped plate 19. A slider 21 is fixedly connected to the end of the arc-shaped rod 20. A horn groove 22 is provided at the edge of the turntable 3. The arc-shaped plate 19 and the slider 21 enter the mounting groove 11 through the horn groove 22. By bringing the two sliders 21 closer together, the two sliders 21 press against the two ends of the arc-shaped plate 19, and then the petri dish 4 is inserted into the mounting groove 11. At this time, the arc-shaped plate 19 and the slider 21 are inserted into the horn groove 22. At this time, the distance between the two sliders 21 is less than the width of the horn groove 22, and the arc-shaped plate 19 and the slider 21 are easily inserted into the horn groove 22.

[0036] The arc plate 19 has a rotating groove 23 in the middle, and a dial 24 rotates in the rotating groove 23. The dial 24 has an inclined angle on both sides, and the dial 24 is pressed against the arc rod 20 on both sides. An elastic plate 25 is fixedly connected in the rotating groove 23 and is pressed against the dial 24. The two arc rods 20 are magnetically attracted to each other.

[0037] By turning the dial 24, the dial 24 rotates in its original position in the rotation slot 23. Since the two sides of the dial 24 are tilted at an angle, and under the action of magnetic attraction, the two arc rods 20 are brought closer to each other, thereby bringing the two sliders 21 closer to each other, so that the sliders 21 and the arc plate 19 can be inserted into the horn slot 22.

[0038] When the slider 21 and the arc plate 19 are engaged in the horn groove 22, the slider 21 and the arc plate 19 are simultaneously located in the mounting groove 11. By continuing to turn the dial 24, the dial 24 rotates within the arc plate 19. The inclined surface of the dial 24 rotates, pressing against the arc rod 20, causing the two arc rods 20 to move away from each other, thereby driving the two sliders 21 to move away from each other. This method allows the arc plate 19 and the slider 21 to rotate within the mounting groove 11 without detaching from the mounting groove 11, thus completing the installation of the petri dish 4 in the mounting groove 11 without affecting the rotation of the petri dish 4 in the mounting groove 11.

[0039] The bottom of the petri dish 4 is fixedly connected to a plug rod 26, and the bottom of the turntable 3 is provided with a plug hole 27. On the one hand, the cooperation between the plug rod 26 and the plug hole 27 further ensures that the petri dish 4 is located in the mounting groove 11. On the other hand, the diameter of the plug rod 26 is slightly smaller than the inner diameter of the plug hole 27, so as not to affect the rotation and slight shaking of the petri dish 4.

[0040] Explanation regarding petri dish 4 rotating on its own axis while undergoing circular motion:

[0041] This application also includes a rotating plate 5 that presses against the petri dish 4. The rotating plate 5 has a movable groove 6 in the middle. A rotating rod 7 that passes through the movable groove 6 is rotatably connected inside the detection box 1. An insert plate 8 and an elastic element 9 are movably connected to the outer surface of the rotating rod 7. The insert plate 8 is inserted into the rotating plate 5. A pressing plate 10 that passes through the rotating plate 5 is also pressed against the outer surface of the rotating rod 7. The pressing plate 10 is in cooperation with the petri dish 4.

[0042] By activating the motor 12 fixedly connected to the outside of the detection box 1, the output shaft of the motor 12 passes into the detection box 1 and is fixedly connected to the rotating rod 7, thereby driving the rotating rod 7 to rotate in its original position. The bottom center of the turntable 3 is rotatably connected to the detection box 1. The rotation of the rotating rod 7 drives the rotating plate 5 to rotate. The two ends of the rotating plate 5 are inserted between two adjacent petri dishes 4. On the one hand, the rotating plate 5 presses against the petri dish 4, causing the turntable 3 to rotate, thereby causing the petri dish 4 to switch positions and make circular motion. On the other hand, while the petri dish 4 is making circular motion, the rotating plate 5 and the petri dish 4 are in relative motion, thereby causing the petri dish 4 to rotate and switch angles, so that light can shine into the other side of the interior of the petri dish 4, ensuring the comprehensive light exposure of the wheat seeds in the petri dish 4.

[0043] Among them, the rotating plate 5 has an elastic anti-slip layer glued to its side, which makes it easy for the rotating plate 5 to drive the petri dish 4 to rotate in a circular motion while rotating itself. When the petri dish 4 rotates in the mounting groove 11, the two sliders 21 are far apart from each other, and the distance between the two sliders 21 is greater than the width of the horn groove 22, so the petri dish 4 will not fall off the mounting groove 11.

[0044] The insert plate 8 is horizontally inserted into the rotating plate 5. A spring 15 is connected between the rotating plate 5 and the insert plate 8. A rotating groove 16 is provided in the rotating plate 5. A connecting post 17 is fixedly connected to the end of the rotating groove 16 and the outer surface of the rotating rod 7. A movable ball 18 is movably embedded on the connecting post 17. The insert plate 8 is connected to one of the movable balls 18. The other two movable balls 18 are connected and engaged by an elastic element 9. A limiting base 14 is fixedly connected to the bottom of the rotating rod 7. The diameter of the limiting base 14 is larger than the inner diameter of the movable groove 6.

[0045] When the rotating rod 7 rotates, the insert plate 8, in conjunction with the spring 15, can rotate a small angle under the action of the movable ball 18 (the insert plate 8 always slides relative to the rotating plate 5). After rotating a small angle, the insert plate 8 moves in a circular motion with the rotating rod 7. The mutual attraction between the second spring 15 and the insert plate 8 causes the rotating plate 5 to sway slightly relative to the rotating rod 7 while rotating with it. This facilitates the rotating plate 5 to drive the petri dish 4 to move in a circular motion and rotate while making a slight sway.

[0046] The pressure plate 10 has a T-shaped structure, and the end of the pressure plate 10 has a magnetic attraction structure. The part of the rotating rod 7 corresponding to the pressure plate 10 has a magnetic structure that magnetically engages with the pressure plate 10. When the middle of the rotating plate 5 contacts the culture dish 4, the culture dish 4 reacts to the pressure plate 10, causing the pressure plate 10 to press against the rotating rod 7, thereby increasing the movement between the rotating rod 7 and the rotating plate 5. The shaking efficiency of the second spring 15 increases, ensuring the shaking efficiency of the rotating plate 5 on the culture dish 4.

[0047] In this application, there are two spotlights 2. One spotlight 2 is located above the center of the turntable 3. The spotlight 2 located in the center of the turntable 3 illuminates all the wheat seeds in the petri dishes 4. A fixed plate 13 is fixedly connected inside the detection box 1. The other spotlight 2 is located on the fixed plate 13. The self-rotating rod 7 is rotatably connected to the fixed plate 13. The other spotlight 2 is located on the fixed plate 13 to supplement the light for the petri dishes 4 whose positions are switched by the rotating plate 5.

[0048] In this application, the mounting groove 11 provides a mounting position for the culture dishes 4 on the turntable 3. The protective arc plate 19 and the arc rod 20 ensure the firm positioning of the culture dishes 4 and allow them to rotate freely. The dial 24 in the rotation groove 23 drives the two arc rods 20 to move closer or further apart through magnetic attraction, thereby adjusting the position of the culture dishes 4. The insertion rod 26 at the bottom of the culture dish 4 cooperates with the insertion hole 27 on the turntable 3 to ensure positioning, while also allowing slight rotational movement. The rotating plate 5 is connected to the detection box 1 through the rotating rod 7. When the rotating rod 7 rotates under the drive of the motor 12, the rotating plate 5 contacts the adjacent culture dishes 4, both pushing the turntable 3 to rotate and gently causing the culture dishes 4 to rotate during the contact, improving the comprehensiveness of illumination. Two spotlights 2 are located on the turntable 3 and the fixed plate 13, respectively. One provides comprehensive illumination to all culture dishes 4, and the other supplements the illumination changes caused by the rotation.
