Description

Technical Field

[0001] This utility model relates to the field of seed disinfection technology, and in particular to a seed disinfection device for indoor wheat germination experiments. Background Technology

[0002] Seed disinfection refers to the technical measures taken before sowing to treat seeds using physical, chemical, or biological methods to kill or inhibit harmful organisms such as pathogens, pests, and weed seeds carried on the surface and inside of the seeds. In agricultural research and teaching, the indoor germination experiment of wheat is an important basic experiment for studying wheat growth and development, genetic breeding, and pest and disease control. Accurate control of the seed disinfection process is crucial for obtaining reliable experimental results, so seed disinfection devices are used to assist in experimental research.

[0003] While existing seed disinfection devices can disinfect seeds, they have some drawbacks in actual use. The entire disinfection process is lengthy, requiring operators to frequently remove and place seeds, and it is impossible to guarantee that the disinfection time and process are consistent for each batch of seeds. Furthermore, when dealing with large-scale seed disinfection operations, it consumes a lot of manpower and makes it even more difficult to ensure the uniformity of the disinfection process.

[0004] Therefore, the existing seed disinfection devices require operators to frequently take out and put in seeds, and cannot guarantee that the disinfection time and process for each seed is consistent. At the same time, when dealing with large-scale seed disinfection operations, they consume a lot of manpower and cannot ensure the uniformity of the disinfection process. This utility model can achieve a series of operations for seeds, from feeding, preliminary disinfection and rinsing, soaking and disinfection to final rinsing and picking, without manual intervention, through the coordinated work of components such as drive motor, rotary motor, first electric telescopic rod and second electric telescopic rod. Utility Model Content

With the help of the filter screen plate, each batch of seeds can be collected in sequence. Then, the first electric telescopic rod tilts the filter screen plate downward, so that the seeds on the filter screen plate enter the subsequent timed soaking disinfection component in sequence, ensuring the uniformity of disinfection.

[0015] 2. The transmission rod drives the connecting fork plate and the seed placement tray to rotate in the tray. One rotation of the seed placement tray can sequentially receive wheat seeds sliding down the filter screen plate, which can achieve the effects of spacing and conveying. Moreover, the time it takes for the seed placement tray to rotate half a circle around the transmission rod is just enough to meet the disinfection requirements of the seeds, ensuring the consistency of disinfection method and time, which is conducive to improving the accuracy and reliability of experimental results.

After the alcohol disinfection is completed, the clean water inlet pipe 210 below is sprayed out from the clean water rinsing port 202.

[0028] A filter screen plate 213 is rotatably connected to the inner wall of the upper operating table 2. A first electric telescopic rod 214 is hinged to the side end of the upper operating table 2. The output end of the first electric telescopic rod 214 is hinged to both sides of the filter screen plate 213. The first electric telescopic rod 214 can tilt the filter screen plate 213 downwards to facilitate the wheat seeds falling into the subsequent disinfection steps.

[0029] The timed soaking and disinfection assembly includes a tray 401, a receiving slot 402, a rotary motor 403, a transmission rod 404, a connecting fork plate 405, a seed placement tray 406, a flipping top plate 407, a tension spring 408, a second electric telescopic rod 409, a connecting horizontal plate 410, a lifting feeding hopper 411, a through groove 412, a clean water spray head 413, a second clean water inlet pipe 414, and a filter tank 415. The tray 401 is installed at the bottom of the inner wall of the soaking tank 4. The receiving slots 402 are symmetrically opened on both sides of the upper end of the tray 401. The receiving slots 402 on both sides of the tray 401 can facilitate the wheat seeds to fall into the seed placement tray 406 and facilitate subsequent removal.

[0030] A rotary motor 403 is installed on the upper end face of the device housing 1. The output shaft of the rotary motor 403 passes through the device housing 1 and is connected to a transmission rod 404. A connecting fork plate 405 is fixed to the outside of the transmission rod 404. A seed placement tray 406 is rotatably connected inside the connecting fork plate 405. A flip-top plate 407 is rotatably connected inside the tray 401. The flip-top plate 407 is located below the seed placement tray 406. A tension spring 408 is installed on the inner wall of the bottom end of the soaking tank 4. The upper end of the tension spring 408 is hinged to the bottom end of the flip-top plate 407. The rotary motor 403 can make the connecting fork plate 405 rotate axially around the transmission rod 404, so that the seed placement tray 406 can transport the placed wheat in sequence.

[0031] A second electric telescopic rod 409 is installed at the upper end of the device housing 1. The output end of the second electric telescopic rod 409 passes through the device housing 1 and is connected to a connecting horizontal plate 410. A lifting feed hopper 411 is fixed to the side end of the connecting horizontal plate 410. The lifting feed hopper 411 is located directly above the tilting top plate 407. The side end of the lifting feed hopper 411 is slidably connected to the inner wall of the soaking tank 4. A through groove 412 is opened on the side end of the inner wall of the soaking tank 4. A clean water spray head 413 is installed at the upper end of the device housing 1. A second clean water inlet pipe 414 is connected to the side end of the clean water spray head 413. Seed feeding port 6 The interior is equipped with a cavity, and a water filter trough 415 is provided at the bottom of the cavity. When the seed placement tray 406 rotates half a turn and reaches above the tilting top plate 407, the second electric telescopic rod 409 pushes the lifting feeding hopper 411 to descend. When the lifting feeding hopper 411 descends, it will squeeze the tilting top plate 407 below, causing the seed placement tray 406 above the tilting top plate 407 to tilt, so that the wheat seeds fall into the lifting feeding hopper 411. Then the second electric telescopic rod 409 retracts, driving the lifting feeding hopper 411 to rise until it is parallel to the through groove 412, so that the wheat seeds fall into the water filter trough 415.

[0032] Working principle: According to Figures 1-4 First, wheat seeds enter the upper operating platform 2 through the feed inlet 3. Then, the drive motor 203 drives the active drive roller 204 to rotate, which in turn drives the driven drive roller 205 to rotate through the belt 206. The separator plate 207 on the belt 206 separates and transports the seeds. When the seeds move to the area below the alcohol output hole 201, the alcohol in the alcohol inlet pipe 208 is atomized by the atomizer 209 and sprayed out from the alcohol output hole 201 to disinfect the seeds with alcohol for thirty seconds. Then, the seeds move to the area below the clean water rinsing hole 202, and the clean water in the first clean water inlet pipe 210 is sprayed out from the clean water rinsing hole 202 to rinse the seeds with clean water for thirty seconds. The wastewater after rinsing is discharged through the drain bucket 211 and the drain pipe 212. The first electric telescopic rod 214 can tilt the filter screen plate 213 downward to facilitate the wheat seeds falling into the subsequent disinfection steps.

[0033] according to Figures 5-7 Next, the wheat seeds falling into the seed placement tray 406 are soaked in the soaking tank 4 with sodium hypochlorite solution. At this time, the rotary motor 403 drives the transmission rod 404 and the connecting fork plate 405 to rotate, which can sequentially transport the wheat in the seed placement tray 406. Half a rotation takes exactly ten minutes. When the seed placement tray 406 has rotated half a rotation and reached above the tilting top plate 407, the second electric telescopic rod 409 pushes the lifting feed hopper 411 to descend. When the lifting feed hopper 411 descends, it will squeeze the tilting top plate 407 below, causing... The seed placement tray 406 above the flip-top plate 407 tilts, causing the wheat seeds to fall into the lifting hopper 411. Then, the second electric telescopic rod 409 retracts, driving the lifting hopper 411 to rise until it is parallel to the through groove 412, causing the wheat seeds to fall into the water filter trough 415. The tension spring 408 can reset the flip-top plate 407 when it is not squeezed. The wheat seeds that have fallen into the water filter trough 415 are rinsed by the clean water spray head 413 for forty-five seconds. At this time, the operator can take out the disinfected seeds from the seed dispensing port 6.

[0034] It should be noted that the aforementioned drive motor 203, atomizer 209, first electric telescopic rod 214, rotary motor 403, and second electric telescopic rod 409 can be powered using existing operating techniques. Whether powered by a power supply unit or by an external wire, these are all conventional operating techniques and will not be described in detail here.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
