[0039] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] Please refer to Figure 1 The present embodiment provides a weight detection device, which includes: a detection box 100, a guide tube 200, a reference plate 300, a base 400, a reference shaft 500, a detection plate 600, a pressure detection sensor 700 and a processor (not shown in the figure).
[0041] The guide tube 200 is installed on the top of the detection box 100, and the guide tube 200 is used to guide the seeds into the detection box 100. Optionally, the guide tube 200 is arranged perpendicular to the top of the detection box 100, and when the weight detection device is used, the guide tube 200 is arranged in the vertical direction.
[0042] The reference plate 300 is fixedly connected to an outer wall of one side of the detection box 100 , the base 400 cooperates with the reference plate 300 , the reference shaft 500 is rotatably installed on the base 400 , the reference shaft 500 is horizontally arranged, and the central axis of the reference shaft 500 is perpendicular to the central axis of the guide tube 200 .
[0043] A notch 110 penetrating the side wall of the detection box 100 close to the reference plate 300 is provided, and a guide port 120 is provided at the bottom of the detection box 100 . The guide port 120 is used to guide the seeds out of the detection box 100 .
[0044] The plate type of the detection plate 600 is a flat plate, the plate surface of the detection plate 600 is arranged parallel to the central axis of the reference shaft 500, the extension direction of the detection plate 600 is arranged perpendicular to the central axis of the reference shaft 500, and the detection plate 600 is matched with the reference shaft 500. Along the circumference of the reference shaft 500, the detection plate 600 is fixedly matched with the reference shaft 500.
[0045] The detection plate 600 extends into the detection box 100 through the notch 110 to receive the seeds introduced into the detection box 100 by the guide tube 200, so that the seeds are bounced off and fall into the guide outlet 120 after hitting the detection plate 600. Specifically, by adjusting the length of the detection plate 600 extending into the detection box 100, the seeds are directly bounced off and fall into the guide outlet 120 after hitting the detection plate 600, that is, each seed only collides with the detection plate 600 once (the seed movement path is as shown in FIG. 1 ). Figure 1 ), as shown by the dotted path K in FIG.
[0046] The reference shaft 500 is fixedly connected to the extrusion part 510, the pressure detection sensor 700 is arranged on the base 400, and an elastic member 520 is abutted between the extrusion part 510 and the pressure detection surface of the pressure detection sensor 700. In a natural state, due to the elastic force of the elastic member 520, the elastic member 520 pushes the extrusion part 510 to rotate the reference shaft 500, so that the detection plate 600 abuts against the upper edge of the notch 110.
[0047] The pressure detection sensor 700 is electrically connected to the processor, and the processor is used to record the detection data of the pressure detection sensor 700 and determine the single seed weight fluctuation data according to the detection data.
[0048] During use, when no seeds enter the detection box 100, the detection plate 600 is stably attached to the upper edge of the notch 110, and the pressure detected by the pressure detection sensor 700 is stable.
[0049] When the seeds are introduced into the detection box 100 from the guide tube 200 one by one, the seeds collide with the detection plate 600 one by one. When the seeds collide, the detection plate 600 effectively amplifies the force arm, so that the pressure detection sensor 700 can more sensitively detect the pressure change caused by the collision of the seeds. Therefore, the weight of the seeds can be confirmed based on the pressure change detected by the pressure detection sensor 700 when the seeds collide with the detection plate 600. In addition, the weight fluctuation data of a single seed can be confirmed by continuously recording the detection data of the pressure detection sensor 700 through the processor.
[0050] Since the single seed weight is positively correlated with the seedling strength index and chlorophyll content, and the root activity of large and medium seeds is significantly higher than that of small seeds, this means that the larger the single seed weight, the higher its germination rate and growth potential are usually.
[0051] During sowing, the guide tube 200 is connected to the outlet of the seed meter, and the seed meter is used to send the seeds into the guide tube 200 one by one, so as to achieve the weight detection of the seeds one by one during the sowing process. In this way, it can be ensured that the weight of a single seed sown is within a reasonable range, thereby effectively reducing the probability of non-germination or poor growth, helping to supervise the sowing process, and helping to improve the uniformity and reliability of sowing, which is particularly effective for large-scale planting.
[0052] In general, the weight detection device provided in this embodiment can detect and monitor the mass of individual seeds during the sowing process, which has positive significance for improving the standardization of sowing and optimizing the sowing quality.
[0053] In this embodiment, when the detection plate 600 abuts against the upper edge of the notch 110 , the detection plate 600 is exactly parallel to the reference plate 300 , and the reference plate 300 extends along the length direction of the detection plate 600 .
[0054] The base 400 is slidably engaged with the reference plate 300 along the length direction of the reference plate 300, and the reference plate 300 is provided with a first locking component (not shown in the figure) for locking the base 400. The detection plate 600 is slidably engaged with the reference shaft 500 along the length direction of the detection plate 600, and the reference shaft 500 is provided with a second locking component (not shown in the figure) for locking the detection plate 600.
[0055] With this design, the position of the base 400 on the reference plate 300 and the position of the detection plate 600 on the reference shaft 500 can be adjusted to adjust the amount of insertion of the detection plate 600 in the detection box 100, and the length of the lever arm of the detection plate 600 on the reference shaft 500 can also be adjusted. In this way, for different types of seeds, the lever arm length and the amount of insertion can be adjusted according to the weight range of the seeds, thereby ensuring the detection sensitivity.
[0056] The present embodiment further provides a system for mixed sowing of oats and perennial forage grasses, which comprises: a sowing mechanism (not shown in the figure), a data center (not shown in the figure) and the above-mentioned weight detection device.
[0057] The weight detection device is arranged between the seeding device (not shown) and the seeding pipeline (not shown) of the sowing mechanism. The seed outlet of the seeding device of the sowing mechanism is connected to the inlet of the guide pipe 200 of the weight detection device, and the guide outlet 120 of the detection box 100 of the weight detection device is connected to the seeding pipeline of the sowing mechanism.
[0058] During the sowing process, the seed meter of the sowing mechanism delivers the seeds into the guide tube 200 one by one, and at the same time, the weight of the seeds is detected one by one.
[0059] The data center is used to perform the evaluation process, which includes the following steps:
[0060] S1. Construct a first area model of a first sowing area, a second area model of a second sowing area, and a third area model of a third sowing area. The first sowing area is used for mixed sowing of oats and perennial forage grass, the second sowing area is used for single sowing of perennial forage grass, and the third sowing area is used for single sowing of oats. The first sowing area, the second sowing area, and the third sowing area have the same shape and area.
[0061] During sowing, the sowing density (the number of seeds per unit area) of perennial forage grasses in the first sowing area is the same as that in the second sowing area, and the sowing density (the number of seeds per unit area) of oats in the first sowing area is the same as that in the second sowing area.
[0062] S2. Determine the weight data of the seeds sown at each position in each sowing area according to the single seed weight fluctuation data detected by the weight detection device and the sowing density of the sowing mechanism, and mark them in the corresponding model. The weight data of the seeds refers to the data of the single seed mass of the sown seeds. In this embodiment, only the weight change of the single seed mass at each position in each sowing area, that is, the relative weight change data, can be recorded.
[0063] S3. Collect the subsequent growth conditions of each sowing area, obtain the growth condition assessment data of each location in each sowing area, and mark them in the corresponding model.
[0064] S4. Evaluate the effect of mixed sowing of oats and perennial forage grasses based on the growth status evaluation data in each sowing area and the correlation between the seed weight data in each sowing area and the growth status evaluation data.
[0065] Specifically, in S4, the evaluation of the mixed broadcasting effect includes the following steps:
[0066] S41, each regional model is divided into a number of unit areas of the same number and size. For example, a 10m*10m area is used as a unit area, and each sowing area and regional model is divided based on this.
[0067] S42. If the seed weight data and the growth condition evaluation data in the second regional model are positively correlated, that is, the larger the single-grain weight of the seeds in the second regional model, the better the growth condition of the perennial forage grass, and the seed weight data and the growth condition evaluation data in the third regional model are also positively correlated, that is, the larger the single-grain weight of the seeds in the third regional model, the better the growth condition of the oats, then each unit area in the first regional model is matched with the unit area corresponding to the seed weight data in the second regional model and the third regional model, that is, for each unit area in the first regional model, a unit area with a similar sowing single-grain weight of perennial forage grass (the error range can be flexibly set according to actual needs) is matched for it in the second regional model, and a unit area with a similar sowing single-grain weight of oats is matched for it in the third regional model (the error range can be flexibly set according to actual needs).
[0068] S43: Evaluate the mixed broadcasting effect according to the matched unit areas.
[0069] Since the single seed weight is positively correlated with the seedling strength index and chlorophyll content, and the root activity of large and medium seeds is significantly higher than that of small seeds, this means that the larger the single seed weight, the higher its germination rate and growth potential are usually.
[0070] Through the above design, the difference in growth conditions caused by the difference in single seed weight can be effectively reduced, which facilitates a more accurate evaluation of the impact of mixed sowing, thereby helping researchers to efficiently improve the mixed sowing plan, which is of positive significance for promoting the research progress of mixed sowing plans.
[0071] The oat and perennial forage mixed seeding system provided in this embodiment can evaluate the effects of mixed seeding more accurately and reasonably, thereby helping researchers to efficiently improve mixed seeding plans, which is of positive significance for promoting the research progress of mixed seeding plans.
[0072] In summary, the weight detection device provided by the embodiment of the present invention can detect and monitor the mass of a single seed during the sowing process, which is of positive significance for improving the standardization of sowing and optimizing the sowing quality. The oat and perennial forage mixed sowing system provided by the embodiment of the present invention can more accurately and reasonably evaluate the effects of mixed sowing, thereby helping researchers to efficiently improve the mixed sowing scheme, which is of positive significance for promoting the research progress of mixed sowing schemes.
[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
