Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting, in particular to a corn seed activity detection device. BACKGROUND

[0002] Seed activity is directly related to crop growth and yield. High-activity seeds can ensure field emergence rate, enhance resistance to adverse environments, and are related to the overall agricultural production efficiency and benefit. It is one of the key factors to achieve food security and sustainable agricultural development. In the production, processing, and sales of seeds, activity detection is an essential step to control seed quality, and is also a necessary means for breeders to select excellent varieties and for seed physiologists to conduct related research. It is of great significance to promote the healthy development of the seed industry.

[0003] At present, a Chinese utility model patent with publication number CN221615522U and publication date August 30, 2024 proposes a seed activity detection device, which includes a bottom plate, a water tank, and a water delivery mechanism. The water tank further includes a filter screen, two sets of filter plates, two shafts, two material taking openings, and two sealing plates. The water delivery mechanism and the water tank are fixedly installed on the bottom plate. The filter screen is fixedly arranged at the lower position inside the water tank. Two shafts are installed on the inner wall of the water tank at the upper position and correspond to each other horizontally. Two filter plates are installed on the two shafts to form a sealing door. Two material taking openings are arranged at the upper and lower positions on the same side of the water tank and are located at the positions of the filter screen and the two filter plates. Two sealing plates are connected to the positions of the two sealing plates on the water tank through screws and bolts. The water delivery mechanism further includes a water delivery pipe and a drain pipe to connect the water tank and the water tank.

[0004] When in use, the two filter plates are placed flat to form a sealing door, and the material taking opening is sealed with the sealing plate to prevent water leakage. The seeds are placed on the sealing door of the water tank, and the water delivery pipe of the water delivery mechanism is opened to deliver water to the water tank until all the seeds are submerged. By rotating the two shafts, the two filter plates are separated to form a gap. The seeds with high activity have high water content and high density, which will slide down to the filter screen through the gap. The seeds with low activity have low water content and low density, which will float on the water surface. After all the seeds are separated, the two filter plates are rotated to be horizontal. At this time, the floating seeds will not fall on the filter screen due to the decrease of water level. After the water is drained through the drain pipe of the water delivery mechanism, the seeds with low activity are left on the filter plate, and the seeds with high activity are left on the filter screen. The sealing door is opened, and the seeds are taken out through the material taking opening.

[0005] For the above technical solution, it is found that after the seeds are separated, the seeds with high activity fall on the filter screen. The seeds located in the deep part of the filter screen need to be pried out with a tool to take out all the seeds. Not only is it inconvenient to take seeds, but also the process of collecting seeds with a tool can cause damage to the seeds. Utility Model Content

[0006] To facilitate quick and easy seed extraction, this invention provides a corn seed activity detection device.

[0007] This utility model provides a corn seed activity detection device, which adopts the following technical solution:

[0008] A corn seed activity detection device includes a housing, a water supply mechanism, a drainage mechanism, and a separation mechanism;

[0009] The top of the box is uncovered, and the water supply mechanism and the drainage mechanism are connected to the box.

[0010] The separation mechanism includes a first filter plate, a first drive assembly, a second filter plate, and a second drive assembly. The first filter plate is rotatably connected to the housing. The first drive assembly is disposed on the housing and is drivenly connected to the first filter plate. The second filter plate is rotatably connected to the housing and is disposed below the first filter plate. The second drive assembly is disposed on the housing and is drivenly connected to the second filter plate. A first retrieval port and a second retrieval port are provided on the side wall of the housing. The first retrieval port is opposite to the first filter plate, and the second retrieval port is opposite to the second filter plate. The housing is also provided with a sealing door for sealing the retrieval ports.

[0011] The water tank is sealed with a sealing door. Seeds are placed on the first filter plate, and the water supply mechanism is turned on to add water to the tank until the corn seeds are submerged. Inactive seeds will float on the surface. At this time, the first drive assembly is used to drive the first filter plate to rotate downwards, causing the more active seeds to sink to the second filter plate. After sinking, the first filter plate is rotated to make it flat and the drainage mechanism is turned on to drain the water from the tank. A collection frame is placed at the sealing door. The sealing door is opened, and the second drive assembly is driven to tilt the second filter plate outwards. The corn seeds roll out from the second collection port and fall into the collection frame due to gravity. By adopting this technical solution, seeds are collected by gravity, eliminating the need for tools and avoiding damage to the corn seeds. It also makes seed collection more convenient and improves collection efficiency.

[0012] Optionally, the second drive assembly includes a second filter plate support plate and a second filter plate shaft; the second filter plate shaft is disposed inside the water tank, and the second filter plate support plate is disposed on the second filter plate shaft.

[0013] By adopting this technical solution, when the shaft of the second filter plate is driven to rotate, the second filter plate tilts outward beyond the water tank, which facilitates collection and prevents corn seeds from slipping into the water tank.

[0014] Optionally, the second filter plate is detachably connected with the second filter plate support plate.

[0015] When the device is used for many times, the bran dust and other substances carried by the corn seeds will stick to the second filter plate, affecting the filtering, and the end far from the taking opening is inconvenient to clean, by adopting the technical scheme, the second filter plate can be detached from the second filter plate support plate and cleaned separately, so that the second filter plate can be normally used for filtering, and the resistance of the corn seeds when sliding down is reduced.

[0016] Optionally, the upper end surface of the second filter plate is arc-shaped.

[0017] By adopting the technical scheme, because the two ends of the second filter plate are inclined to the middle, the seeds will gather to the middle position of the filter screen in the sliding process, reducing the possibility of the seeds falling from the two ends of the second filter plate in the pouring process.

[0018] Optionally, the sealing door is connected with the water tank through a hinge, and a locking block is further arranged above the sealing door and rotationally connected to the outer wall of the water tank.

[0019] By adopting the technical scheme, when the device is used, the sealing door is closed, and the locking block is rotated to seal the water tank, reducing the complexity of the sealing work and the work pressure, and the sealing ring plays a further sealing role.

[0020] Optionally, baffles are further arranged at the two ends of the sealing door and connected with the sealing door.

[0021] When the second filter plate is driven to rotate, the seeds on the second filter plate will fall on the sealing door in the sliding process to the taking opening, and by adopting the technical scheme, the seeds falling on the sealing door can be prevented from splashing and falling from the two ends of the sealing door.

[0022] Optionally, a scraping mechanism is further arranged on the first filter plate and includes the scraper, and the scraper is slidingly connected to the second filter plate.

[0023] Because of the surface tension of water, the seeds after being wetted will be adhered to the first filter plate and cannot freely slide, by adopting the technical scheme, the scraper is pulled out, and the seeds adhered to the first filter plate will be pushed to the taking opening by the scraper, further facilitating the seed taking work.

[0024] Optionally, the scraping mechanism further includes two connecting plates and a handle, the two connecting plates are respectively connected with the two ends of the scraper, the two ends of the handle are respectively connected to the two connecting plates, and the handle is arranged on the side close to the opening.

[0025] By adopting this technical solution, the scraper, the two connecting plates, and the handle form a frame, which can stabilize the movement direction of the scraper. When the scraper is pulled out, it will not be pulled out at an angle due to one side of the scraper moving faster than the other or the force position of the scraper being biased to one side, causing the scraper to get stuck on the first filter plate and unable to continue working.

[0026] In summary, this utility model has at least one of the following beneficial technical effects:

[0027] 1. The rotating and tilting design of the second filter plate makes the process of collecting corn seeds after separation more convenient and reduces the possibility of damage to the corn seeds when using tools for collection. At the same time, the second filter plate can be disassembled for easy cleaning, reducing the adhesion of grain bran and dust and its impact on the filtration efficiency of the second filter plate.

[0028] 2. The sealed door makes it easy to seal the water tank during use, simplifying the sealing process. The baffle reduces the probability of corn seeds splashing during collection.

[0029] 3. When the surface tension of water prevents corn seeds from sliding freely, the scraper can push the seeds adhering to the first filter plate toward the collection port, further facilitating seed removal. Furthermore, the scraping mechanism forms a frame that stabilizes the scraper's movement and prevents it from jamming. Attached Figure Description

The box body 1 is not covered at the top, the water feeding mechanism 2 and the water draining mechanism 3 are connected to the box body 1, and the sealing door 5 is connected to the water tank through a hinge.

[0039] The water tank side wall is sealed by using the sealing door 5, the corn seeds are put into the water tank, the water feeding mechanism 2 is opened to feed water into the water tank, the corn seeds with high activity and the corn seeds with low activity are separated, then the water draining mechanism 3 is opened to drain the water in the water tank, and the sealing door 5 is opened to take out the corn seeds.

[0040] Reference Figures 1 to 4 The separating mechanism 4 comprises a first filter plate 401, a first driving assembly 402, a second filter plate 403, and a second driving assembly 404; the first filter plate 401 and the first driving assembly 402 are arranged above the second filter plate 403 and the second driving assembly 404.

[0041] The first driving assembly 402 comprises a first driving machine and a first filter plate rotating shaft 4021. The first driving machine is arranged on the outer wall of the water tank, and the first filter plate rotating shaft 4021 is arranged inside the water tank, one side of which penetrates through the inner wall of the water tank and is connected to the first driving machine. A fixed block 4023 is fixedly arranged on the inner wall of the water tank and used for supporting the first filter plate rotating shaft 4021 to keep it horizontal. The first filter plate 401 is arranged on the first filter plate rotating shaft 4021. The first driving machine, the first filter plate rotating shaft 4021, the fixed block 4023, and the first filter plate 401 are all arranged in two groups and arranged oppositely at the same horizontal height.

[0042] The second driving assembly 404 comprises a second filter plate support plate 4041, a second filter plate rotating shaft 4042, and a second driving machine. The second driving machine is arranged on the outer wall of the water tank, and the second filter plate rotating shaft 4042 is arranged inside the water tank, one side of which penetrates through the inner wall of the water tank and is connected to the first driving machine. The second filter plate support plate 4041 is arranged on the second filter plate rotating shaft 4042, and the second filter plate 403 is detachably connected to the second filter plate support plate 4041 through bolts. The upper end surface of the second filter plate 403 is arc-shaped.

[0043] The sealing door 5 is further provided with a locking block 501 which is rotationally connected to the outer wall of the water tank. In order to further prevent the water tank from overflowing, the sealing door 5 is further provided with a sealing ring which is arranged on the contact surface of the sealing door 5 and the water tank. The sealing door 5 is further provided with a baffle 502 at both ends which is fixedly connected to the sealing door 5.

[0044] Therefore, when in use, the sealing door 5 is closed, the locking block 501 is twisted to lock the sealing door 5, the side wall of the water tank is sealed to prevent water from overflowing, the two first filter plates 401 are placed flat to ensure that there is no gap between the two filter plates, the seeds are placed on the first filter plates 401, the water feeding mechanism 2 is opened to add water into the tank 1 until the corn seeds are completely submerged, the first driving mechanism is driven to rotate the first filter plates 401 downward so that a gap is formed between the two filter plates of the first filter plates 401, and the seeds with higher activity can sink to the second filter plates 403. After the corn seeds sink, the two filter plates of the first filter plates 401 are rotated until they are placed flat to block, the water drainage mechanism 3 is opened to drain the water in the water tank, the sealing door 5 is opened, the second driving mechanism is driven to tilt the second filter plates 403 to the outside of the water tank, and the corn seeds roll out of the second material outlet by gravity and fall into the collection frame.

[0045] Reference Figure 5 The first filter plates 401 are further provided with a scraping mechanism which includes a scraper 601, two connecting plates 602 and a handle 603. The two connecting plates 602 are respectively connected to both ends of the scraper 601, and the two ends of the handle 603 are respectively connected to the two connecting plates 602. The handle 603 is arranged in an arc shape, and the scraper 601, the two connecting plates 602 and the handle 603 form a frame. The two connecting plates 602 are respectively slidably connected to both ends of the second filter plates 403. The connecting plate 602 is provided with a sliding strip on the contact surface with the filter plate. The sliding strip is wider at the end away from the connecting plate 602 than at the end connected to the connecting plate 602. The filter plate is provided with a corresponding sliding groove. The opening width of the sliding groove is smaller than the width of the end of the sliding strip away from the connecting plate 602.

[0046] Therefore, due to the existence of water tension, when the gravity is smaller than the water tension, the corn seeds may stick to the second filter plates 403 and cannot freely slide. The handle 603 is held to pull out the scraper 601. The scraper 601 can scrape the corn seeds during the pulling-out process. The design of the sliding groove and the sliding strip can prevent the scraper 601 from being pulled out from above the second filter plates 403 during the pulling-out process so that the scraper 601 cannot normally work.

[0047] The implementation principle of the embodiment is as follows:

[0048] Close the sealing door 5 and twist the locking block 501 to lock the sealing door 5, prevent the water tank from overflowing, place the two filter plates of the first filter plate 401 without gap, place the seeds on the first filter plate 401, open the water feeding mechanism 2 to feed water to the water tank until the corn seeds are all submerged, after the seeds with light quality float on the water surface, drive the first drive to make the first filter plate 401 rotate downward to form a gap between the two filter plates, and the seeds with high activity sink to the second filter plate 403. After sinking, place the first filter plate 401 flat and drain the water in the water tank, open the sealing door 5, drive the second drive to make the second filter plate 403 tilt to the outside of the water tank, and the corn seeds roll and slide out of the second material outlet and fall into the collecting frame by gravity. When the water tension between the corn seeds and the second filter plate 403 is greater than the gravity, some corn seeds will adhere to the second filter plate 403, the scraper 601 is pulled out, and the corn seeds are scraped off the filter plate by the scraper 601 and fall into the collecting frame.
