Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a soil angle of accumulation measuring device. Background Technology

[0002] The angle of repose of soil refers to the maximum angle formed between the slope and the horizontal plane when granular materials (such as soil particles) are naturally deposited. It mainly reflects the combined influence of the internal friction between soil particles and factors such as particle shape and size on the deposition morphology.

[0003] In razor clam farming along the coast of Zhejiang Province, researchers discovered that soil texture and the angle of accumulation significantly impact the growth and yield of razor clams. The bottom sediment of the razor clam farming ponds in this region is primarily a mixture of sand and mud. Researchers measured the angle of accumulation in different ponds and analyzed the results in conjunction with razor clam growth indicators. The results showed that in ponds with an angle of accumulation between 30° and 40°, razor clams grew faster, had a higher survival rate, and yielded relatively higher yields. Ponds with excessively large or small angles of accumulation negatively affected both growth and yield to varying degrees. An excessively large angle of accumulation resulted in a compacted bottom, making it difficult for razor clams to burrow, thus affecting their habitat and feeding. An excessively small angle of accumulation resulted in a loose bottom, which was easily altered by water flow and tides, leading to unstable burrows that were easily buried.

[0004] Therefore, for burrowing mollusks, such as razor clams and mud clams, a suitable angle of soil deposition ensures the stability of their burrows. For example, in a sandy-muddy substrate with a moderate angle of soil deposition, the substrate is less prone to collapse under tidal fluctuations and water flow, allowing mollusks to safely inhabit it. Burrows provide mollusks with shelter from predators and harsh environments, and a stable burrow environment contributes to their growth and reproduction.

[0005] By measuring the angle of accumulation (ACI), a suitable growth environment can be found for shellfish. An appropriate ACI provides suitable substrate conditions, which are conducive to the attachment and growth of benthic algae. Algae are one of the important food sources for shellfish. When the ACI is moderate, the roughness and porosity of the soil surface are suitable for algal spore attachment and provide a certain degree of stability for algal growth. For example, in some intertidal shellfish farming areas, a suitable ACI allows benthic algae such as diatoms to proliferate in large quantities, providing abundant food for shellfish. A suitable ACI also facilitates the accumulation and decomposition of organic matter in the soil. When algae die, their remains and other organic matter decompose in the soil, releasing nutrients that can be absorbed and utilized by shellfish or further promote the growth of new algae. At the same time, a suitable ACI can also prevent excessive accumulation of organic matter, which can lead to oxygen deficiency and the production of harmful substances, ensuring the quality and sustainability of the food supply. Ensuring that shellfish can obtain sufficient nutrients, thereby promoting their growth and development and improving their quality and yield, is of great significance for the sustainable development of shellfish farming.

[0006] Currently, soil angle of repose measurement has many drawbacks: 1. Traditional measurement involves manually piling up the soil to be tested, which cannot guarantee the slope of the soil pile, resulting in large operational errors, significant differences in measurement results among different personnel, and low efficiency, with a cumbersome and time-consuming process; 2. Particle angle of repose measuring instruments have stringent environmental requirements, requiring a dust-free environment, and are complex, with high professional thresholds for operation and maintenance, and are expensive; 3. Sand and gravel angle of repose measuring devices are costly, rely on complex image acquisition and processing technologies, and have high requirements for sample particle uniformity; 4. Particle angle of repose measuring devices for soils with different moisture contents have poor field applicability, are inconvenient to transport and use in special sites, and are large in size and occupy a lot of space.

[0007] To address the above technical issues, a soil angle of repose measuring device and its measuring method are proposed. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a soil angle of accumulation measuring device that is small in size, stable in structure, and simple to operate. It has no environmental requirements and can measure the soil angle of accumulation in any environment. It can also be transported and used in special sites. Furthermore, it ensures that the falling speed of the soil to be measured is stable, reduces the evaporation of soil moisture, reduces the measurement error of the soil angle of accumulation, and ensures the accuracy of the measurement.

[0009] The technical problem solved by this utility model is achieved through the following technical solution:

[0010] A soil angle of accumulation measuring device includes a base, a measuring platform, a support mechanism, a lifting mechanism, a drive mechanism, a soil leakage pipe, and a soil leakage pipe. The base and the measuring platform are connected by the support mechanism. The lifting mechanism and the drive mechanism are symmetrically installed on the upper end of the base. The drive mechanism is located at the front end of the lifting mechanism. The lifting mechanism passes through the measuring platform and is used to support the lifting platform parallel to the upper end of the measuring platform. The soil leakage pipe passes through the center of the lifting platform and is located at the upper end of the measuring platform. Soil to be measured is placed in the soil leakage pipe. The drive mechanism drives the lifting mechanism to push the lifting platform and move the soil leakage pipe up or down.

[0011] Furthermore, the lifting mechanism includes a push rod assembly, the push rod housing of the push rod assembly is symmetrically located at the upper end of the base and the lower end of the measuring platform, the push rod of the push rod assembly is located inside the push rod housing, the upper end of the push rod protrudes from the push rod housing, and the push rod is driven to rise or fall by a drive mechanism.

[0012] Furthermore, the drive mechanism includes a servo motor, a main gear, and a driven gear. The output shaft of the servo motor is connected to the main gear, the main gear is meshed with the driven gear, and the driven gear is connected to the push rod via a fixed lead screw. The servo motor drives the main gear and the driven gear to mesh and rotate, and pushes the push rod assembly up or down via the fixed lead screw.

[0013] Furthermore, the center of the measurement platform is the soil-falling area.

[0019] The advantages and positive effects of this utility model are:

[0020] 1. The soil accumulation angle measuring device of this utility model uses a servo motor to drive the main gear and the driven gear to mesh and rotate. The fixed screw pushes the push rod to drive the lifting platform with the soil leakage tube fixed to it to rise. The soil to be tested in the soil leakage tube falls smoothly and evenly into the soil falling area in the center of the measuring platform.

[0034] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0035] like Figures 1 to 8 As shown, a soil angle of accumulation measuring device includes a base 9, a measuring platform 3, a support mechanism, a lifting mechanism, a drive mechanism, a lifting platform 2, and a soil leakage pipe 1. The base 9 and the measuring platform 3 are connected by the support mechanism. The lifting mechanism and the drive mechanism are symmetrically installed on the upper end of the base 9. The drive mechanism is located at the front end of the lifting mechanism. The lifting mechanism passes through the measuring platform 3 and is used to support the lifting platform 2, which is parallel to the upper end of the measuring platform 3. The soil leakage pipe 1 passes through the center of the lifting platform 2 and is located at the upper end of the measuring platform 3. Soil to be measured is placed in the soil leakage pipe 1. The lifting mechanism is driven by the drive mechanism to push the lifting platform 2 to move the soil leakage pipe 1 up or down.

[0036] The lifting mechanism includes a push rod assembly. The push rod housing 6 of the push rod assembly is symmetrically located in the recessed platform at the upper end of the base 9 and at the lower end of the measuring platform 3. The push rod 5 of the push rod assembly is located inside the push rod housing 6. The upper end of the push rod 5 protrudes from the push rod housing 6, and the lower end of the push rod 5 is provided with an internal thread. The push rod 5 is driven to rise or fall by a drive mechanism.

[0037] The drive mechanism includes a servo motor 7, a main gear 11, and a driven gear 12. The servo motor 7 is symmetrically located in the recessed platform at the upper end of the base 9 and at the front end of the push rod housing 6. The output shaft of the servo motor 7 is connected to the main gear 11, which meshes with the driven gear 12. The driven gear 12 is connected to the push rod 5 through a fixed lead screw 13. The servo motor 7 precisely and smoothly drives the main gear 11 and the driven gear 12 to mesh and rotate, and pushes the push rod 5 up or down through the fixed lead screw 13. During the up or down process, the push rod 5 precisely drives the lifting platform 2, which is closely connected to it, to rise or fall. The rising or falling speed of the lifting platform 2 has been strictly adjusted to ensure efficiency without affecting the accumulation effect of the soil to be tested due to excessive speed.

[0038] The soil drain tube 1 is used to hold the soil to be tested. The outer perimeter of the drain tube 1 is covered by an insulating film 10, which provides a seal and reduces soil moisture evaporation. This creates a closed space around the soil, allowing evaporated moisture to condense inside the insulating film 10 and fall back onto the soil surface, maintaining high air and soil humidity. In cold weather, the insulating film 10 reduces heat loss from the soil by preventing heat from dissipating into the atmosphere through convection and radiation. In hot weather, the insulating film 10, with its shading function, reflects some sunlight, reducing the amount of heat entering the soil and preventing damage from high temperatures.

[0039] The center of the measuring platform 3 is the soil drop area 4. The soil to be measured leaks out of the soil drop pipe 1 and falls into the soil drop area 4 to form a pile for measurement. The measuring platform 3 has symmetrical through holes at both ends for the lifting mechanism to pass through.

[0040] The lifting platform 2 has a through hole in the center, and the support mechanism is an X-type support frame 8 or an H-type support frame 8.

[0041] The base 9 is the supporting part of the soil accretion angle measuring device, providing a stable platform for other components of the soil accretion angle measuring device. It helps to ensure that the soil accretion angle measuring device is in a horizontal position. For the soil accretion angle measuring device, horizontal placement is a basic requirement for accurate measurement. Without a stable base 9, the measurement operation will be interfered with, resulting in inaccurate measurement results.

The driven gear 12 is screwed to the push rod 5 through a fixed screw 13.

[0044] The base 9 is connected to the measuring platform 3 via an X-shaped support frame 8. The push rod housing 6 and the servo motor 7 located at the front end of the push rod housing 6 are respectively installed in the symmetrical recesses at the upper end of the base 9. The push rod 5 is installed inside the push rod housing 6. The upper end of the push rod 5 protrudes from the push rod housing 6, and the lower end of the push rod 5 is provided with an internal thread. The upper end of the push rod 5 passes through the through holes symmetrically opened at both ends of the measuring platform 3 to support the measuring platform 3. The center of the measuring platform 3 is the soil drop area 4. The center of the lifting platform 2, which is parallel to the upper end of the measuring platform 3, is opened with a through hole. The soil leakage pipe 1 passes through and is fixed in the through hole opened in the center of the lifting platform 2 and is located at the upper end of the measuring platform 3. The soil to be tested is placed in the soil leakage pipe 1. The servo motor 7 drives the main gear 11 and the driven gear 12 to mesh and rotate. Through the fixed screw 13, the push rod 5 drives the lifting platform 2, which is fixed with the soil leakage pipe 1, to rise or fall. The soil to be tested falls smoothly into the soil drop area 4 in the center of the measuring platform 3 during the rising process.

[0045] Example 2

[0046] A soil angle of accumulation measuring device includes a base 9, a measuring platform 3, a support mechanism, a lifting mechanism, a drive mechanism, a lifting platform 2, and a soil leakage pipe 1. The lifting mechanism includes a push rod assembly, which includes a push rod housing 6 and a push rod 5. The drive mechanism includes a servo motor 7, a main gear 11, and a driven gear 12. The output shaft of the servo motor 7 is connected to the main gear 11, and the main gear 11 is meshed with the driven gear 12. The driven gear 12 is screwed to the push rod 5 through a fixed screw 13.

[0047] The base 9 is connected to the measuring platform 3 via an H-shaped support frame 8. The push rod housing 6 and the servo motor 7 located at the front end of the push rod housing 6 are respectively installed in the symmetrical recesses at the upper end of the base 9. The push rod 5 is installed inside the push rod housing 6. The upper end of the push rod 5 protrudes from the push rod housing 6, and the lower end of the push rod 5 is provided with an internal thread. The upper end of the push rod 5 passes through the through holes symmetrically opened at both ends of the measuring platform 3 to support the measuring platform 3. The center of the measuring platform 3 is the soil drop area 4. The center of the lifting platform 2, which is parallel to the upper end of the measuring platform 3, is opened with a through hole. The soil leakage pipe 1 passes through and is fixed in the through hole opened in the center of the lifting platform 2 and is located at the upper end of the measuring platform 3. The soil to be tested is placed in the soil leakage pipe 1. The servo motor 7 drives the main gear 11 and the driven gear 12 to mesh and rotate. Through the fixed screw 13, it pushes the push rod 5 to drive the lifting platform 2, which is fixed with the soil leakage pipe 1, to rise or fall. The soil to be tested falls smoothly into the soil drop area 4 in the center of the measuring platform 3 during the rising process.

[0048] The working principle of this utility model:

[0049] In the initial production state of the soil accumulation angle measuring device, the servo motor 7 drives the main gear 11 and the driven gear 12 to mesh and rotate, and pushes the push rod 5 through the fixed screw 13 to drive the lifting platform 2 with the soil leakage pipe 1 fixed to it to descend, so that the lower end of the soil leakage pipe 1 contacts the center of the measuring platform 3.

[0050] The soil to be tested is placed in the soil leakage tube 1. The servo motor 7 drives the main gear 11 and the driven gear 12 to mesh and rotate. The fixed lead screw 13 pushes the push rod 5 to drive the lifting platform 2, which is fixed with the soil leakage tube 1, to rise. The soil to be tested in the soil leakage tube 1 falls smoothly and evenly into the soil falling area 4 in the center of the measuring platform 3 to form a pile. After the soil to be tested is stable, the piled soil forms a cone. The angle formed by the generatrix of the cone and the base of the cone is measured using a protractor, which is the soil accumulation angle.

[0051] This utility model relates to a soil angle of accumulation measuring device. A servo motor 7 drives a main gear 11 and a driven gear 12 to mesh and rotate. A fixed lead screw 13 pushes a push rod 5, which in turn lifts a lifting platform 2 with a fixed soil-leaking tube 1. The soil to be tested, inside the soil-leaking tube 1, falls smoothly and evenly into the soil-falling area 4 at the center of the measuring platform 3. The servo motor 7 ensures the stability of the soil's descent speed, resulting in better soil accumulation and more accurate test results. The soil-leaking tube 1 has an insulation film 10 around its outer perimeter, providing a seal and reducing soil moisture evaporation, thus minimizing measurement error in the soil angle of accumulation. The support mechanism is an X-shaped or H-shaped support frame 8, ensuring structural stability and making the soil fall more smoothly into the soil-falling area 4, further reducing measurement error in the soil angle of accumulation. The device is small in size, simple to operate, and has no environmental requirements; it can measure the soil angle of accumulation in any environment and can be transported to special sites, making it convenient to use.
