Description

Technical Field

[0001] This invention belongs to the technical field of agricultural product testing equipment, specifically relating to a stalk strength testing device for testing the lodging resistance of sugarcane. Background Technology

[0002] Sugarcane, an important economic crop in my country, is widely used in sugar production, bioenergy, and other fields. Its yield and quality directly affect the economic benefits of related industries. Southern my country is a major sugarcane producing area, where extreme weather events such as typhoons and torrential rains are frequent. Sugarcane stalks are tall, hollow, and have a high center of gravity, making them highly susceptible to lodging. Lodging not only leads to stalk breakage and root damage, causing direct yield losses, but also promotes the growth of pests and diseases, reduces sugar accumulation in the stalks, and increases harvesting difficulty and costs, seriously hindering the high-quality development of the sugarcane industry. Therefore, accurately assessing the lodging resistance of sugarcane varieties and selecting superior lodging-resistant varieties is of great significance for optimizing sugarcane cultivation management and enhancing the industry's resilience.

[0003] One of the core evaluation indicators for sugarcane lodging resistance is stalk strength. The toughness and bending resistance of the stalk directly determine its ability to withstand wind and rain impacts. Currently, the industry's methods for testing sugarcane stalk strength are mainly divided into two categories: traditional manual assessment and instrumental testing. Traditional manual assessment often involves observing the lodging rate in the field and manually bending the stalk to judge toughness. This method is simple to operate but highly subjective, greatly influenced by the experience of the testing personnel, unable to quantify stalk strength data, and has poor repeatability, making it difficult to meet the precise needs of variety breeding and cultivation optimization.

[0004] Existing instrumental testing methods largely draw upon crop stalk strength testing equipment, primarily including compressive strength testers and bending test machines. However, these devices have significant limitations: First, they have poor adaptability. Most are designed for short-stalked crops such as wheat and corn, and cannot be adapted to the robust and long stalks of sugarcane. The fixing mechanism can easily damage the stalks, and it is difficult to simulate the lodging stress scenario of sugarcane under natural conditions. Second, their testing functions are limited, only able to detect local compressive strength or single-point bending force of the stalk, unable to reproduce the overall bending and stretching lodging process of sugarcane under wind and rain, resulting in insufficient correlation between the test data and actual lodging resistance. Third, they are cumbersome to operate. Some devices rely on manual adjustment of angles and forces, leading to low testing efficiency and a lack of precise control over the bending angle, making it impossible to obtain stalk strength data under different degrees of lodging.

[0005] Furthermore, while some existing specialized testing devices attempt to simulate sugarcane lodging scenarios, their structural designs still have shortcomings. For example, the fixing mechanisms of some devices lack stability, causing the sugarcane to easily shift during testing, resulting in large errors in force measurement. Some devices use manual drive to adjust the bending angle, which cannot achieve uniform and stable force loading, making it difficult to reflect the true resilience of the stalks. At the same time, most devices lack angle measuring components, making it impossible to accurately correspond to the stalk strength at different lodging angles, and thus failing to provide multi-dimensional data support for lodging resistance performance evaluation.

[0006] In summary, existing sugarcane stalk strength testing technologies suffer from poor adaptability, unrealistic testing scenarios, low data quantification accuracy, and cumbersome operation, making it difficult to meet the demand for precise testing data in sugarcane lodging-resistant variety breeding and cultivation technology optimization. Therefore, developing a sugarcane stalk strength testing device with a reasonable structure, strong adaptability, the ability to simulate real lodging scenarios, and precise detection of angle and force values ​​has become an urgent need for the technological upgrading of the sugarcane industry.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] This invention provides a stalk strength testing device for testing the lodging resistance of sugarcane, aiming to solve the technical problems mentioned in the background art above.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows:

[0010] A stalk strength testing device for testing the lodging resistance of sugarcane includes a base, a rotating mechanism, and a testing mechanism.

[0011] Two vertical screen panels are spaced apart on the base, and a sugarcane fixing cylinder is provided between the two vertical screen panels on the base. A rotating mechanism is rotatably connected to the inner side of each of the two vertical screen panels, and the detection mechanism is rotatably connected to the upper end of the rotating mechanism.

[0012] Preferably, the detection mechanism includes a housing, a push-pull force gauge, and a push-pull assembly.

[0013] The housing is rotatably connected to the rotating mechanism via a rotating shaft. The push-pull force gauge is installed inside the housing, and its telescopic end is connected to the push-pull assembly. The push-pull assembly is slidably installed inside the housing.

[0014] Preferably, the push-pull assembly includes a connecting seat, a slider, a sliding plate, and a fixing member.

[0015] The sliding plate component is slidably connected to the inner side of the housing via the slider. The inner side of the slider is provided with the connecting seat, which is connected to the telescopic end of the push-pull force gauge.

[0016] The sliding plate component has a clearance groove for avoiding the rotating shaft, and the end of the sliding plate component away from the slider is rotatably connected to the fixing component.

[0017] Preferably, the fixing component includes a semi-circular plate and a fastening bolt, the semi-circular plate being rotatably connected to the sliding plate, and the fastening bolt being provided on its edge.

[0018] Preferably, the rotating mechanism includes a turntable and a deflector plate.

[0019] The turntable is rotatably connected to the inner side of the vertical screen panel, and the deflection plate is provided at its upper end. The detection mechanism is rotatably connected to the deflection plate.

[0020] Preferably, the system also includes a cylinder, one end of which is connected to the base and the other end of which is hinged to the side end face of the turntable.

[0021] Preferably, the vertical screen panel is provided with a dial.

[0022] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0023] 1. This invention provides a stalk strength testing device for testing the lodging resistance of sugarcane. Taking into account the structural characteristics of the thick and long sugarcane stalks, the device designs the structure of the sugarcane fixing cylinder and the fixing component, which respectively realize the lower end limit and upper end clamping and fixing of the sugarcane. The clamping force of the fastening bolt can be adjusted to avoid damage to the stalk during the fixing process, and at the same time prevent the sugarcane from shifting during the test, thus solving the problems of poor adaptability and unstable fixing of existing equipment.

[0024] 2. This invention uses a cylinder-driven rotating mechanism to drive the detection mechanism to bend the sugarcane, accurately reproducing the overall bending and tensile stress process of sugarcane lodging caused by wind and rain under natural conditions. Compared with the existing equipment's detection method of single-point bending and local pressure resistance, the detection scenario is more realistic, and the data is more correlated with the actual lodging resistance performance of sugarcane.

[0025] 3. This invention, when combined with a digital push-pull force gauge and a dial, can read the stem force value corresponding to different bending angles (30°, 45°, 60°, etc.) in real time, achieving precise control of both angle and force value. This solves the shortcomings of existing equipment that cannot quantify data and lack multi-dimensional support, providing a precise basis for lodging resistance performance evaluation.

[0034] 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.

[0035] Example

[0036] like Figures 1 to 6 As shown, a stalk strength testing device for testing the lodging resistance of sugarcane includes a base 1, a rotating mechanism 2 and a testing mechanism 3. Two vertical screen plates 11 are spaced apart on the base 1, and a sugarcane fixing cylinder 12 is provided on the base 1 between the two vertical screen plates 11. A rotating mechanism 2 is rotatably connected to the inner side of each of the two vertical screen plates 11, and the testing mechanism 3 is rotatably connected to the upper end of the rotating mechanism 2.

[0037] This device is made of hard metal materials such as stainless steel or aluminum alloy, which takes into account both structural strength and corrosion resistance. It is suitable for use in various scenarios such as fields and laboratories. All components work together to realize the function of detecting the strength of sugarcane stalks.

[0038] The base 1 is a rectangular flat plate structure, and an anti-slip pad can be added to its lower end to improve the overall stability during testing. Two vertical screen plates 11 are welded parallel to each other along the length of the upper surface of the base 1. The vertical screen plates 11 are set perpendicular to the base 1, and the distance between the two vertical screen plates 11 is slightly larger than the outer diameter of the sugarcane fixing cylinder 12. The corresponding positions on the inner side walls are rotatably connected to the rotating mechanism 2 through the rotating shaft 100. The sugarcane fixing cylinder 12 is a cylindrical structure with two through ends, which can be threaded onto the base 1. Its inner diameter can be designed to be replaceable according to the diameter of common sugarcane stalks to ensure that it can be adapted to sugarcane samples of different thicknesses.

[0039] In this embodiment, please refer to Figure 2 and Figure 3 The detection mechanism 3 includes a housing 31, a push-pull force gauge 32, and a push-pull assembly 33. The housing 31 is rotatably connected to the rotating mechanism 2 via a rotating shaft 100. The push-pull force gauge 32 is located inside the housing 31, and its telescopic end is connected to the push-pull assembly 33. The push-pull assembly 33 is slidably mounted on the inner side of the housing 31. The housing 31 is a hollow rectangular cavity. The push-pull force gauge 32 can be purchased from the market as a conventional device. It has zeroing and data locking functions and can display the force value in real time.

[0040] Specifically, the push-pull assembly 33 includes a connecting seat 331, a slider 332, a sliding plate 333, and a fixing member 334. The sliding plate 333 is slidably connected to the inner side of the housing 31 via the slider 332. The inner side of the slider 332 is provided with a connecting seat 331, which is connected to the telescopic end of the push-pull force gauge 32. The sliding plate 333 is provided with a clearance groove 3331 for avoiding the rotating shaft 100. The end of the sliding plate 333 away from the slider 332 is rotatably connected to the fixing member 334.

[0041] In this example, slider 332 is a strip-shaped parallel guide rail, and a groove is provided on housing 31 to cooperate with slider 332. Slide plate 333 is slidably connected to the inside of housing 31 through slider 332 and groove. When rotating mechanism 2 rotates, it drives slide plate 333 to slide. During this process, slide plate 333 stretches and bends sugarcane to simulate the situation of sugarcane falling over. During the process of slide plate 333 stretching sugarcane, it squeezes push-pull force gauge 32 through connecting seat 331. Then, the force value is read through the display panel of push-pull force gauge 32. The strength of sugarcane's resistance to falling over can be judged by the magnitude of the force value. The setting of clearance groove 3331 can avoid the rotating shaft 100 from interfering with the sliding operation of slide plate 333.

[0042] In this embodiment, please refer to Figure 4The fixing component 334 includes a semi-circular plate 3341 and a fastening bolt 3342. The semi-circular plate 3341 is rotatably connected to the sliding plate 333, and the fastening bolt 3342 is provided on its edge. The semi-circular plate 3341 is an arc-shaped metal plate with an arc adapted to the outer diameter of the sugarcane stalk. It is rotatably connected to the end of the sliding plate 333 away from the slider 332. The semi-circular plates 3341 of the two detection mechanisms 3 are arranged opposite to each other. Threaded holes are opened at corresponding positions on the edges of the two semi-circular plates 3341. The fastening bolt 3342 passes through the threaded holes to lock the two together. By adjusting the tightness of the fastening bolt, the upper end of sugarcane of different thicknesses can be stably clamped.

[0043] In this embodiment, the rotating mechanism 2 includes a turntable 21 and an inclined plate 22. The turntable 21 is rotatably connected to the inner side of the vertical screen plate 11, and the inclined plate 22 is provided at its upper end. The detection mechanism 3 is rotatably connected to the inclined plate 22. The turntable 21 is a circular metal disc, which is rotatably connected to the inner side of the vertical screen plate 11 through a bearing. The rotation axis of the turntable 21 is perpendicular to the surface of the vertical screen plate 11. The inclined plate 22 is a rectangular metal plate, which is integrally formed with the upper end of the turntable 21. The end of the inclined plate 22 away from the turntable 21 is rotatably connected to the detection mechanism 3 through a rotating shaft 100, which ensures that the posture of the detection mechanism 3 can be adaptively adjusted when the rotating mechanism 2 deflects.

[0044] Please refer to Figure 5 and Figure 6 The invention also includes a cylinder 4, one end of which is connected to the base 1 and the other end is hinged to the side end face of the turntable 21; a scale 5 is provided on the vertical screen plate 11.

[0045] To achieve automated operation, the device is equipped with cylinder 4. The tail of cylinder 4 is hinged to the upper surface of the base via a hinged seat, and the end of the piston rod is hinged to the side surface of turntable 21. Cylinder 4 is an adjustable telescopic speed model. The turntable rotates at a uniform speed through air pressure control, thereby ensuring that the sugarcane is subjected to uniform bending force and simulating the gradual process of natural lodging. The center of the scale 5 coincides with the rotation center of turntable 21, and is marked with key detection angle scale lines such as 30°, 45°, and 60°. This allows the testing personnel to read the force values ​​of the sugarcane under different conditions when turntable 21 rotates to key detection angles such as 30°, 45°, and 60° through the push-pull force gauge 32.

[0046] Working principle of the invention:

[0047] This invention provides a stalk strength testing device for testing the lodging resistance of sugarcane. In specific use, a sugarcane stalk with uniform growth and free from pests and diseases is selected for testing. A sugarcane fixing cylinder 12 with an appropriate inner diameter is selected according to the thickness of the stalk. The lower end of the sugarcane is inserted into the fixing cylinder 12 to complete the lower end limiting and fixing. The upper end of the sugarcane is placed between the semi-circular plates 3341 of the two testing mechanisms 3. The semi-circular plates 3341 are adjusted to fit the surface of the stalk, and the fastening bolts are tightened. Through the clamping action of the two semi-circular plates 3341, the upper end of the sugarcane is stably fixed, ensuring that there is no displacement of the upper and lower ends during the testing process.

[0048] Turn on the push-pull force gauge 32 and complete the zeroing operation. Check the connection status of the cylinder, rotating mechanism, and detection mechanism 3 to confirm that each component is operating normally. According to the experimental requirements, determine the preset detection bending angle, such as 30°, 45°, or 60°, and mark the corresponding angle position on the scale 21.

[0049] The inspector observes the dial 21. When the sugarcane bends to the preset angle, the control cylinder 4 stops moving and locks the force value data displayed by the push-pull force gauge 32 (if the values ​​of the push-pull force gauge 32 on the two testing mechanisms are different, the average value can be taken). This force value is the tensile force value of the sugarcane at the corresponding lodging angle. The larger the force value, the stronger the stalk toughness and bending resistance, and the better the lodging resistance. Conversely, the smaller the force value, the weaker the lodging resistance.

[0050] After a single sample is tested, the piston rod of the control cylinder 4 retracts, driving the rotating mechanism 2 and the detection mechanism 3 to reset. The fastening bolt 3342 is loosened, the sugarcane sample is removed, and the next sample to be tested is replaced. The above steps are repeated to achieve efficient testing of batch samples.

[0051] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
