Description

Technical Field

[0001] This invention relates to the field of rice testing technology, specifically to a rice seed germination rate testing device. Background Technology

[0002] Before rice seed cultivation or planting, it is necessary to test the germination rate of the seeds. Currently, most testing methods involve planting 100 seeds in soil, cultivating them for a period of time, and then counting the number of germinated seeds to obtain the germination rate.

[0003] However, rice seeds often contain broken grains during harvesting, which normally do not germinate. Directly using these broken grains for germination testing would negatively impact the germination rate. Therefore, it's necessary to remove the broken grains. Currently, the only option for sieving is using existing vibrating screens. While this achieves the desired effect, the limited seed quantity in experiments makes it costly. Furthermore, the vibrating screens generate significant mechanical vibration, inevitably causing contact between the rice seeds and the machine, which could further damage them.

[0009] As a further embodiment of the present invention, the wind-driven module further includes an air supply unit, which includes a valve seat installed on the experimental chamber and a blower fixedly connected to the experimental chamber. A ventilation hose is connected to the air outlet of the blower, and the ventilation hose is connected to the valve seat. Both connecting pipes of the two sets of blowers are connected to the valve seat.

[0010] As a further embodiment of the present invention, the wind drive module further includes two sets of symmetrically arranged wind direction switching parts, each set of wind direction switching parts corresponding to a set of blower parts;

[0011] The airflow switching unit includes a piston cylinder fixedly connected to the exhaust duct. A piston push rod is slidably connected inside the piston cylinder. A filter plate is fixedly connected to the piston push rod. The filter plate is slidably connected to the exhaust duct.

A connecting pipe two is connected to the side of the piston cylinder away from the filter plate. An arc-shaped piston sleeve is connected to the end of the connecting pipe two away from the piston cylinder.

[0012] A ball valve is rotatably connected inside the valve seat. An L-shaped valve hole is opened inside the ball valve. The ventilation hose on the blower is connected to the lower end of the L-shaped valve hole. A rotating shaft is fixedly connected to the ball valve. An arc-shaped piston rod is fixedly connected to the rotating shaft. The two ends of the arc-shaped piston rod are slidably connected to the arc-shaped piston sleeves of two sets of airflow switching parts.

[0013] As a further embodiment of the present invention, the upper end of the mounting base is provided with a sealing cover for sealing, the sealing cover and the detection plate are spaced one centimeter apart on one side, and the air outlet of the exhaust duct is one centimeter.

[0014] As a further embodiment of the present invention, the exhaust duct is also provided with an empty rice grain removal mechanism, the empty rice grain removal mechanism including a mesh cover, the mesh cover being inclined upward and connected to the side of the exhaust duct near the connecting pipe, and the lower end of the mesh cover being connected to a collection hopper.

[0015] As a further embodiment of the present invention, a heating cylinder is also provided inside the experimental chamber, the heating cylinder extending through the experimental chamber, and a mounting plate is provided inside the experimental chamber.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1.

At the same time, it can continuously remove rice grains from the seeds above the detection plate. When multiple sets of detection plates need to be filled, the grains are gradually removed as the process progresses, which increases the subsequent filling efficiency. Moreover, the overall structure is relatively simple and the cost of use is low.

[0020] 3.

Detailed Implementation

[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 to 8 The present invention provides a technical solution: a rice seed germination rate detection device, including an experimental chamber 01, wherein the experimental chamber 01 is provided with a removal mechanism for removing broken grains from the rice seeds to be tested;

[0034] The removal mechanism includes a workbench module, which includes a mounting base 04 fixedly connected to the experimental box 01. A removable drawer 05 is slidably connected inside the mounting base 04. A detection plate 19 is attached to the top of the mounting base 04 via a snap fastener. One hundred development grooves 20 are arrayed on the detection plate 19. The development grooves 20 are in the shape of an inverted convex character.

[0035] It also includes a wind-driven module for rolling rice seeds on the upper surface of the detection plate 19.

[0036] In use, first insert drawer 05 into mounting base 04 from the front until drawer 05 is securely locked onto mounting base 04. Then, attach detection plate 19 from above drawer 05. At this point, the upper surface of detection plate 19 and the lower inner wall of exhaust duct 07 are level. Take out more than one hundred rice seeds and place them on detection plate 19. Then, blow air through the wind drive module. The air will cause the seeds to roll back and forth on detection plate 19 from one end to the other. When the seeds roll, they will fall into development groove 20. At this time, because development groove 20 is convex (e.g., ... Figure 8 As shown in the figure, when the broken seeds pass through the development trough 20, because the broken seeds are shorter, they will not stay in the development trough 20 and will fall directly through the development trough 20, while the intact seeds are longer and will stay on the development trough 20.

[0037] It can remove broken seeds, improving the accuracy of experiments and reducing the difficulty of manual selection, making it more convenient to use; moreover, the wind-driven method reduces the impact force and frequency between the seeds and the device, reducing damage to the seeds.

[0038] In addition, to improve the accuracy of the experiment, multiple groups of seeds were tested, with one hundred seeds in each group. The average value was then taken, resulting in more accurate experimental data. Since there are one hundred development slots 20, they can be quickly filled by a wind drive. This is especially useful when multiple test plates 19 need to be filled, as it also removes broken seeds. The wind drive device is more efficient and convenient to use. Furthermore, having one hundred development slots 20 facilitates the subsequent counting of germinating seeds. Since each slot is fixed, it also allows for counting with existing equipment, such as image counting, and comparison of images before and after germination.

[0039] As a further embodiment of the present invention, the wind-driven module comprises two sets of symmetrically arranged blower sections. Each blower section includes an exhaust duct 07 fixedly connected to the mounting base 04. The air outlet of the exhaust duct 07 faces inward toward the mounting base 04, and the bottom surface of the inner wall of the air outlet and the upper surface of the detection plate 19 are horizontally transitioned. One end of the exhaust duct 07 located outside the mounting base 04 is connected to a connecting pipe 09.

[0040] Airflow is blown into the exhaust duct 07 through the connecting pipe 09, and then blown onto the detection plate 19 through the air outlet of the exhaust duct 07, thus realizing the function of blowing rice seeds to roll. Since there are two sets of exhaust ducts 07 symmetrically arranged, the seeds can roll back and forth on the detection plate 19.

[0041] As a further embodiment of the present invention, the wind-driven module also includes an air supply unit, which includes a valve seat 10 installed on the experimental chamber 01 and a blower 11 fixedly connected to the experimental chamber 01. A ventilation hose is connected to the air outlet of the blower 11, and the ventilation hose is connected to the valve seat 10. The two connecting pipes 09 of the two sets of blowers are both connected to the valve seat 10.

[0042] When the blower 11 is working, it can generate air, which will be blown into the valve seat 10 through the ventilation hose on the blower 11, and then sent into the connecting pipe 09 through the valve seat 10, and then blown into the exhaust duct 07.

[0043] As a further embodiment of the present invention, the wind drive module also includes two sets of symmetrically arranged wind direction switching parts, each set of wind direction switching parts corresponding to a set of blowers.

[0044] The airflow switching unit includes a piston cylinder 25 fixedly connected in the exhaust duct 07. A piston push rod 26 is slidably connected in the piston cylinder 25. A filter plate 24 is fixedly connected to the piston push rod 26. The filter plate 24 is slidably connected to the exhaust duct 07. A spring is sleeved on the piston push rod 26 to reset the filter plate 24 to the side away from the piston cylinder 25. A connecting pipe 22 is connected to the side of the piston cylinder 25 away from the filter plate 24. An arc-shaped piston sleeve 16 is connected to the end of the connecting pipe 22 away from the piston cylinder 25.

[0045] A ball valve 13 is rotatably connected inside the valve seat 10. An L-shaped valve hole 14 is opened inside the ball valve 13. The ventilation hose on the blower 11 is connected to the lower end of the L-shaped valve hole 14. A rotating shaft 15 is fixedly connected to the ball valve 13. An arc-shaped piston rod 17 is fixedly connected to the rotating shaft 15. The two ends of the arc-shaped piston rod 17 are slidably connected to the arc-shaped piston sleeves 16 of the two sets of airflow switching parts.

[0046] In order to fill all the development slots 20 on the detection plate 19 with seeds, the seeds need to be continuously tumbled on the detection plate 19. At the same time, in order to reduce the cost of use, the number of blowers and the cost of CNC are reduced.

[0047] In use, as the seeds roll to one side on the detection plate 19 until they reach the exhaust duct 07, the seeds continue to roll and accumulate to one side. Under the action of the wind, the seeds push the filter plate 24 towards the side closer to the connecting pipe 09. This causes the filter plate 24 to move the piston rod 26. The piston rod 26 then pushes the hydraulic oil in the piston cylinder 25 through the connecting pipe 12 into the arc-shaped piston sleeve 16. The hydraulic oil in the arc-shaped piston sleeve 16 then pushes the arc-shaped piston rod 17 against the arc-shaped piston. The sleeve 16 slides on the ball valve 13. Since the arc-shaped piston rod 17 and the rotating shaft 15 are fixedly connected, the arc-shaped piston rod 17 will drive the rotating shaft 15 to rotate. When the rotating shaft 15 rotates, it will drive the ball valve 13 to rotate, thereby adjusting the communication direction of the L-shaped valve hole 14 inside the ball valve 13, so that the L-shaped valve hole 14 is connected to another connecting pipe 09, thereby enabling the two connecting pipes 09 to achieve alternating ventilation and the two exhaust ducts 07 to achieve alternating air outlet. Therefore, the function of rice seeds rolling back and forth on the detection plate 19 can be realized.

[0048] It can enable rice seeds to roll back and forth on the detection plate 19, ensuring that the development groove 20 on the detection plate 19 is filled. At the same time, it can continuously remove rice grains from the seeds above the detection plate 19. When multiple sets of detection plates 19 need to be filled, the grains are gradually removed as the process progresses, which increases the subsequent filling efficiency. Moreover, the overall structure is relatively simple and the cost of use is low.

[0049] As a further embodiment of the present invention, the upper end of the mounting base 04 is provided with a sealing cover 06 for sealing, the sealing cover 06 and the detection plate 19 are close to each other on one side with a distance of one centimeter, and the air outlet of the exhaust duct 07 is one centimeter.

[0050] After the rice is placed on the detection plate 19, although the exhaust duct 07 can achieve straight airflow and make the rice roll, in order to increase the rolling speed of the rice and the speed at which the rice enters the development trough 20, the sealing cover 06 is put on at this time, which can form a narrower air duct, ensuring that the rice will not get stuck while rolling quickly.

[0051] As a further embodiment of the present invention, an empty rice grain removal mechanism is also provided on the exhaust duct 07. The empty rice grain removal mechanism includes a mesh cover 08, which is inclined upward and connected to the side of the exhaust duct 07 near the connecting pipe 09. The lower end of the mesh cover 08 is connected to a collection hopper 23.

[0052] Since empty rice grains still exist inside the rice seeds, they cannot germinate and will affect the experimental results just like broken grains, so they need to be removed.

[0053] The exhaust duct 07 is provided with an upward-sloping section. Under the action of wind, the seeds, being heavier, can only roll on the detection plate 19, while the empty rice grains, being lighter, are blown by the airflow through the exhaust duct 07 to the mesh cover 08, and then fall into the collection hopper 23 to be collected, thus achieving the separation of empty rice grains.

[0054] When collecting hopper 23 is implemented, since empty rice grains are relatively light, it is not easy for collecting hopper 23 to detach from net cover 08. Therefore, collecting hopper 23 can be connected to net cover 08 by plugging it in, which is convenient for installation and disassembly. At this time, due to the use of alternating air blowing, after the empty rice husks enter net cover 08, when the air blowing is switched in exhaust duct 07, the airflow stops and the empty rice grains will automatically fall into collecting hopper 23 under the action of gravity, realizing automatic collection and preventing blockage of net cover 08, which would affect the flow of air.

[0055] Since the airflow continuously blows into the mounting base 04, and the airflow also needs to flow out of the mounting base 04 to achieve airflow circulation, the set mesh cover 08 can discharge the airflow and ensure the positive flow of the airflow, thereby ensuring the blowing effect on the seeds; in addition, it can also remove empty rice grains at the same time, improving the accuracy of the experiment, and achieving the removal of broken grains at the same time, with a very simple structure.

[0056] As a further embodiment of the present invention, a heating cylinder 03 is also provided inside the experimental chamber 01, the heating cylinder 03 extends through the experimental chamber 01, and a mounting plate 02 is provided inside the experimental chamber 01.

[0057] When germinating seeds, the test plate 19 containing the seeds can be placed directly into the experimental chamber 01 and placed on the support plate 02. At this time, the water in the experimental chamber 01 needs to cover the upper surface of the test plate 19. Then, the ventilation hose connected to the blower 11 and the valve seat 10 and the heating cylinder 03 are connected to achieve the effect of oxygenating the water in the experimental chamber 01 and promoting rapid seed germination.

[0058] As a further embodiment of the present invention, a slot 21 is provided on the mounting base 04, and a wedge 22 is slidably connected in the slot 21. A flap 18 is hinged to the lower end of the air outlet of the exhaust duct 07. A connecting rod 28 is hinged to the drawer 05 and the end of the wedge 22 located inside the mounting base 04. A spring that can reset the wedge 22 outward is provided in the slot 21. A limiting block 27 that limits the movement position of the wedge 22 is provided on the inner wall of the slot 21.

[0059] Once the development slot 20 in a test plate 19 is full of seeds, the test plate 19 needs to be removed. Most of the excess rice seeds will be located near the filter plate 24, but some may accumulate on the side of the exhaust duct 07 near the test plate 19. This is to prevent the seeds from falling directly into the drawer 05 from the exhaust duct 07 outlet and thus being wasted.

[0060] like Figure 7 When the detection plate 19 is installed into the mounting base 04, pressing the detection plate 19 horizontally downward will push the right side of the wedge 22, causing the wedge 22 to slide to the left into the slot 21. This will pull the flip plate 18 downward through the connecting rod 28 until the flip plate 18 is horizontal. At this time, the detection plate 19 will be against the flip plate 18, completing the installation. When the detection plate 19 is removed, the wedge 22 will move outward under the action of the spring, which will push the flip plate 18 upward through the connecting rod 28. This will cause the rice seeds to slide into the exhaust duct 07, preventing them from falling into the drawer 05 and reducing waste.

[0061] When the detection plate 19 is installed into the mounting base 04, the flip plate 18 can be automatically flipped to prevent seeds from falling into the drawer 05, thus reducing seed waste. At the same time, after the detection plate 19 is installed, the two wedges 22 can clamp the detection plate 19 from the left and right sides to fix the detection plate 19. When the detection plate 19 is taken out, since the side of the wedge 22 closest to the detection plate 19 is inclined, and the spring will cause the wedge 22 to continuously press against the detection plate 19, the flip plate 18 will rotate upward at the same time as the detection plate 19 is taken out, instead of only rotating upward when the detection plate 19 is completely taken out. This ensures the flip plate 18 flips effectively and reduces the chance of seeds falling into the drawer 05.
