Description

Technical Field

[0001] The present invention relates to the technical field of seed cultivation and detection, and in particular to a detection device for the germination ability of seeds that facilitates image acquisition. Background Art

[0002] The germination ability of seeds refers to the ability of seeds to germinate under suitable temperature, humidity and oxygen conditions. The germination ability of seeds is one of the important indicators to measure the quality of seeds, and seeds with better performance can be obtained through cultivation experiments.

[0003] Currently, the detection boxes used to detect the germination ability of seeds usually have a box structure. Components required for seed germination, such as supplementary light lamps, temperature and humidity detection devices, temperature and humidity control devices, and culture dishes, are arranged inside the box. In order to obtain the situation of seed germination, imaging and shooting equipment is usually arranged inside the box, and after imaging, the germination ability of the seeds is analyzed and obtained through an external analysis software and hardware system.

[0004] However, the existing detection equipment still has deficiencies in use: 1. The components in the detection box for improving soil and water and fertilizer do not have a disassembly function, and there is a problem of difficult comprehensive cleaning, resulting in the subsequent use of other seed cultures. Bacteria grow on these components, affecting the germination of seeds, and thus the germination ability of seeds cannot be accurately obtained; 2. The camera used to extract the germination state of seeds is easily adsorbed with moisture in the box due to being in the box for a long time, which affects the camera's clear acquisition of images at each stage during seed germination, thereby affecting subsequent analysis and processing.

[0005] Therefore, the present invention proposes a detection device for the germination ability of seeds that facilitates image acquisition. Summary of the Invention

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0042] Embodiment 1

[0043] Please refer to Figure 1-11 , a detection device for the seed germination ability facilitating image acquisition, including a detection box 1, an image acquisition part 2 and a petri dish groove 3. When in use, an openable sealing door (not shown in the figure) is arranged on the front side of the detection box 1, and then a temperature and humidity detection and control device is installed in the detection box 1. This part of the device is prior art and will not be described in detail in this application. An image-taking camera 21 is arranged on the image acquisition part 2 for taking images of the seed germination situation, and the petri dish groove 3 is used for placing the soil required for seed germination.

[0044] In this technical solution, a detachable upward spiral water and fertilizer tank 4 is arranged in the detection box 1. That is to say, when the whole spiral water and fertilizer tank 4 is lifted upward, it can be separated from the detection box 1. The spiral water and fertilizer tank 4 is rotatably connected to the detection box 1. A number of culture dish grooves 3 evenly distributed along the spiral direction are arranged on the spiral surface of the spiral water and fertilizer tank 4. When the spiral water and fertilizer tank 4 rotates, it can drive the culture dish grooves 3 on it to revolve. The bottom of the culture dish groove 3 is communicated with the inner cavity of the spiral water and fertilizer tank 4 through a water absorption part 31, and the two are in rotational and vertical sliding cooperation. That is to say, the spiral water and fertilizer tank 4 stores water and fertilizer, and then supplies the liquid nutrients required for germination to each culture dish groove 3 through the water absorption part 31. Among them, the spiral water and fertilizer tank 4 has the function of supplying liquid to each culture dish groove 3 equally. That is to say, the dose of water and fertilizer obtained by each culture dish groove 3 is equal. Therefore, all the culture dish grooves 3 are in an equal feeding environment.

[0045] Specifically, the spiral water and fertilizer tank 4 includes a middle pipe 41, a spiral pipe 42, a sluice gate 43 and a transmission shaft 44. The spiral pipe 42 is fixedly sleeved outside the middle pipe 41. The cross-section of the spiral pipe 42 is approximately rectangular. A sluice gate 43 close to the downstream side of the water absorption part 31 is vertically penetrated and slidably connected on the spiral box body of the spiral pipe 42. Specifically, when implementing, jacks for sealing cooperation with the sluice gate 43 can be opened on the upper and lower sides of the spiral box body. Therefore, all the sluice gates 43 divide the spiral pipe 42 into several vertically spiral distributed liquid storage cavities for storing water and fertilizer. One side of the sluice gate 43 is penetrated with an overflow port 431 close to the top. When the overflow port 431 is located in the spiral pipe 42 and close to the top, at this time, each liquid storage cavity will be in a state of storing water and fertilizer liquid equally due to the overflow effect. When in use, a water and fertilizer liquid transmission pipe can be installed at the top of the spiral pipe 42. The transmission shaft 44 is sleeved in the middle pipe 41 and the two are in vertical sliding cooperation. A connecting rod 441 fixedly connected to the top of the sluice gate 43 is fixedly connected to the outer periphery of the transmission shaft 44. The function of the transmission shaft 44 is to control the synchronous up and down movement of all the sluice gates 43. This setting has the functions of controlling the amount of water and fertilizer liquid stored in the liquid storage cavity and blocking the liquid storage cavity.

[0046] Among them, the water absorption part 31 includes an upper pipe 311, a lower pipe 312 and a water absorption strip 313. The water absorption strip 313 is a tubular structure with built-in absorbent cotton. The fixing of the water absorption strip 313 is sleeved inside the upper pipe 311. The absorbent cotton inside the water absorption strip 313 extends into the culture dish groove 3. The upper pipe 311 is sleeved inside the lower pipe 312 and the two are rotationally matched. The top of the upper pipe 311 is fixedly connected to the bottom of the culture dish groove 3. A connecting pipe 421 sleeved outside the lower pipe 312 is fixedly connected to the spiral of the spiral pipe 42. The bottom of the connecting pipe 421 is close to the bottom wall inside the liquid storage cavity. The connecting pipe 421 and the lower pipe 312 are slidably matched up and down, and a blocking valve 4211 is adhesively bonded to the bottom inside it. When the upper pipe 311 rotates, it can drive the culture dish groove 3 to rotate, so that all seeds can be evenly illuminated. When the lower pipe 312 moves up and down, it can drive the water absorption strip 313 to enter and exit the above-mentioned liquid storage cavity. The blocking valve 4211 is a silicone sheet structure with a round hole in the middle. The aperture of the round hole is smaller than the outer diameter of the water absorption strip 313. When the bottom of the water absorption strip 313 is above the blocking valve 4211, the blocking valve 4211 will approximately block the water and fertilizer in the liquid storage cavity from being transmitted to the corresponding culture dish groove 3 through the water absorption strip 313. This setting can further improve the equality of each culture dish groove 3 in obtaining the water and fertilizer solution. Specifically, when the water and fertilizer solution in the spiral pipe 42 flows, it will fill the spiral pipe 42. When the flowing water and fertilizer solution in the spiral pipe 42 is in a filling state, the water and fertilizer solution will enter the lower pipe 312, resulting in the problem of uneven liquid supply to all culture dish grooves 3. Therefore, the blocking valve 4211 is provided. During use, when the lower pipe 312 moves down to penetrate the blocking valve 4211 and moves up to leave the blocking valve 4211, the blocking valve 4211 is approximately in a closed state, so that the lower pipe 312 is approximately in a blocked state.

[0047] Among them, the outer peripheral wall of the lower pipe 312 is fixedly connected to the top of the adjacent gate plate 43 through an arm plate 3121. Specifically, during implementation, a connecting shaft with its top fixedly connected to the arm plate 3121 is welded to the top of the gate plate 43. That is to say, when the gate plate 43 moves up and down, it can synchronously drive the lower pipe 312 to move up and down through the arm plate 3121.

[0048] Further, a rotary sealing door 5 is provided on one side of the detection box 1. Specifically, in the specific implementation, it is preferred that the middle parts of the upper and lower ends of the rotary sealing door 5 are fixedly connected to positioning shafts 51 that are rotatably connected to the upper and lower sides inside the detection box 1. The bottom of the detection box 1 is fixedly connected to a control motor 11 whose output shaft is fixedly connected to the adjacent positioning shaft 51. During use, a sealing gasket is adhered to the outer periphery of the rotary sealing door 5 to ensure that the rotary sealing door 5 can seal the open end on one side of the detection box 1, and the control motor 11 provides driving force for the rotation of the rotary sealing door 5. A detection base 6 is slidably connected up and down on one side of the rotary sealing door 5. Specifically, in the specific implementation, a slide rail can be installed on one side of the rotary sealing door 5, and then a chute that slidably cooperates with the slide rail is opened on the detection base 6. When the rotary sealing door 5 rotates, it can transfer the detection base 6 from a state inside the detection box 1 to a state outside the detection box 1. Among them, the top of the detection base 6 is connected to a suspension plate 8 whose one end extends into the spiral gap of the spiral water and fertilizer tank 4. The suspension plate 8 is an L-shaped rod structure. The image acquisition unit 2 includes an imaging camera 21, and the imaging camera 21 is located at the bottom of the suspension plate 8. During use, the imaging camera 21 is specifically located at a position near the top inside the spiral gap of the spiral water and fertilizer tank 4, aiming to image the seeds in the passing culture dish groove 3. When the rotary sealing door 5 makes the imaging camera 21 located outside the detection box 1, it is convenient to clean the water stains or water mist on the lens of the imaging camera 21.

[0049] Further, a grooved pulley 61 is provided on one side of the detection base 6, and a spiral driving plate 7 is fixedly sleeved outside the spiral water and fertilizer tank 4. Specifically, the spiral driving plate 7 is fixedly sleeved outside the spiral pipe 42, and the outer edge of the spiral driving plate 7 passes through the groove of the grooved pulley 61. Thus, when the spiral pipe 42 rotates, the spiral driving plate 7 will drive the entire detection base 6 to move up and down under the restriction of the grooved pulley 61, so that the imaging camera 21 can pass above each culture dish groove 3. This setting enables the rotation of the spiral pipe 42 to provide driving force for the up and down movement of the detection base 6 through the spiral driving plate 7.

[0050] A control structure for controlling the rotation and liquid supply functions of the spiral water and fertilizer tank 4 is provided at the bottom of the detection box 1. The control structure is detachably connected to the spiral water and fertilizer tank 4, and the control structure includes a grooved lower positioning frame 12 and a support rotating sleeve 15.

[0051] Specifically, a trough-shaped lower positioning frame 12 is fixedly connected to the bottom of the detection box 1. A transmission sleeve 1211 is sleeved on the cross beam 121 of the lower positioning frame 12. The transmission sleeve 1211 is rotatably arranged. During use, a gear or a pulley can be fixedly sleeved on the transmission sleeve 1211, and then a power input structure (gear transmission or belt transmission) for driving the transmission sleeve 1211 to rotate is installed externally. A support rotating sleeve 15 opposite to the transmission sleeve 1211 is arranged on the lower end surface of the detection box 1. The lower part of the middle pipe 41 is inserted into and detachably matched with both the transmission sleeve 1211 and the support rotating sleeve 15. The specific insertion structure can adopt a multi-edge head structure. A trough-shaped mounting frame 123 is fixedly connected to the bottom of the trough-shaped lower positioning frame 12. A telescopic rod 1231 is fixedly connected to the bottom of the trough-shaped mounting frame 123. The telescopic rod 1231 can be a cylinder or an oil cylinder. The output shaft of the telescopic rod 1231 is rotatably connected to an adapter sleeve 12311. The adapter sleeve 12311 is inserted into and matched with the bottom of the transmission shaft 44, and the two are locked and connected by a bolt 123111. Specifically, a threaded hole for screwing with the bolt 123111 is formed through the adapter sleeve 12311. When the bolt 123111 is tightened, one end abuts against the outer peripheral wall of the transmission shaft 44. Thus, when the telescopic rod 1231 expands and contracts, it can control the up and down movement of the transmission shaft 44.

[0052] In this embodiment, an entrance and exit 13 is opened at the top of the detection box 1. A cover 411 is fixedly sleeved on the middle pipe 41 near the top. The cover 411 is used to block the entrance and exit 13. A limiting ring 14 coaxial with the entrance and exit 13 is welded on the upper end surface of the detection box 1. The limiting ring 14 is in clearance fit with the cover 411. This setting makes the cover 411 be limited by the limiting ring 14 when it contacts the top wall of the detection box 1, and at the same time is convenient for sealing fit and can provide the strength for supporting the middle pipe 41.

[0053] Furthermore, a lifting frame 4111 is welded on the top of the cover 411. A lifting opening is opened at the top of the lifting frame 4111, which is convenient for external overhead traveling crane to lift and place. A trough-shaped upper frame 41111 is arranged in the lifting frame 4111. A connecting pipe 411111 coaxial with the middle pipe 41 is fixedly connected to the trough-shaped upper frame 41111. During use, the connecting pipe 411111 is connected to the external water and fertilizer solution supply pipeline through a hose, and the other end is rotatably and hermetically connected to the top of the above-mentioned water and fertilizer solution transmission pipe. Thus, it is convenient for the external water and fertilizer pipeline to transmit water and fertilizer into the rotating spiral pipe 42.

[0054] Among them, a discharge port is opened at the downstream end of the spiral pipe 42, and then an annular sink is opened at the bottom in the detection box 1, and then a discharge pipe is connected to the annular sink. During use, the overflowing water and fertilizer solution in the spiral pipe 42 will flow into the annular sink and finally be discharged by the discharge pipe.

[0055] In this embodiment, a driving assembly 9 for driving the rotation of the petri dish groove 3 is further provided on the hanging plate 8. Preferably, in specific implementation, the driving assembly 9 includes a driving motor 91, a driving friction wheel 92 and a driven friction wheel 93. The driving motor 91 is fixedly arranged on one side of the hanging plate 8 and its output shaft is fixedly connected to the driving friction wheel 92. Specifically, in implementation, a mounting plate is welded on one side of the hanging plate 8, and the driving motor 91 is fixedly mounted on one side of the mounting plate. The driven friction wheel 93 is fixedly sleeved on the upper tube 311 and is in frictional cooperation with the driving friction wheel 92. In use, the driving friction wheel 92 and the driven friction wheel 93 adopt a wheel body structure with an outer rubber sleeve. Thus, when the driving friction wheel 92 and the driven friction wheel 93 are in contact, when the driving friction wheel 92 is controlled to rotate, the driven friction wheel 93 will be driven to rotate, and then the corresponding petri dish groove 3 will be driven to rotate, facilitating the imaging camera 21 to take images of the seed germination in the petri dish groove 3 without dead angles.

[0056] Working principle: In use, when it is necessary to collect images of the germination states of a large number of seeds planted in the spirally distributed petri dish grooves 3, the middle tube 41 is controlled to rotate, and at the same time, the imaging camera 21 is started. The spiral driving plate 7 operates and drives the detection machine base 6 to move through the grooved wheel 61. When the imaging camera 21 is located above one of the petri dish grooves 3, at the same time, the driving friction wheel 92 and the driven friction wheel 93 are in contact, and then the driving motor 91 is started. The driving friction wheel 92 drives the driven friction wheel 93 to rotate, and the petri dish groove 3 rotates. At this time, the imaging camera 21 takes images of the seed germination in the petri dish groove 3 without dead angles. After the imaging is completed, the middle tube 41 is controlled to rotate to take images of the seed germination in the next petri dish groove 3.

[0057] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered by the protection scope of the present invention.
