Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a centrifugal analysis device for soil testing. Background Technology

[0002] In soil testing, centrifugation is commonly used to extract organic and inorganic components from the soil. For example, centrifugation can be used to extract the content of nutrients such as heavy metals, ammonia nitrogen, and phosphate in the soil, and then combined with other analytical methods for quantitative analysis. Simultaneously, centrifugation can also be used to separate soil microorganisms and soil particles, enabling rapid and accurate analysis of soil microbial abundance and microbial community structure.

[0003] During use, centrifugal analyzers experience significant vibration due to the high-speed rotation inside. However, most existing centrifugal analyzers lack damping and shock absorption structures, which reduces their lifespan.

[0004] Therefore, we propose a centrifugal analysis device for soil testing. Utility Model Content

An electric push rod is fixedly installed on the rear side of the top of the protective shell, and the movable end of the electric push rod is fixedly installed on the rear side of the sliding plate.

[0008] Optionally, the turntable is coaxially arranged with the output end of the drive motor, and multiple placement slots are evenly opened in the middle of the turntable, with each of the multiple placement slots being at a different distance from the center of the turntable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This centrifugal analysis device for soil testing, by setting up a buffer component, when the drive motor drives the turntable to rotate, the turntable vibrates, causing the annular cover to vibrate and tilt accordingly. By setting up two symmetrically set swing rods, when the annular cover shakes in the horizontal direction, it squeezes the horizontal buffer component on one side, which widens the angle between the two swing rods. At the same time, it stretches the tension spring, and under the action of the tension spring, the swing rods merge, pushing the inner shell to the initial middle position, thereby improving the stability of the protective shell during use and reducing the loss caused by vibration.

[0015] 2. This centrifugal analysis device for soil testing uses multiple evenly distributed placement slots to place samples in placement tubes. When different centrifugal forces are required to centrifuge the samples, the appropriate placement slot can be selected based on the required centrifugal force and the distance between the placement slot and the center of the rotating frame and the turntable. This allows for different centrifugal forces, enabling more precise control of the centrifugation degree of the soil samples, thereby improving the centrifugation efficiency and facilitating the control of the centrifugation degree.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a centrifugal analysis device for soil testing, including a protective shell 1. A fixed support 2 is fixedly installed at the bottom inside the protective shell 1. A buffer assembly 8 is provided on the side inside the protective shell 1. A drive motor 3 is fixedly installed at the bottom of the fixed support 2. A turntable 4 located above the fixed support 2 is fixedly installed at the output end of the drive motor 3. A placement groove 5 is opened in the middle of the turntable 4. A rotating frame 6 is rotatably connected inside the placement groove 5. A placement tube 7 is provided through the middle of the rotating frame 6. An annular cover 9 is fixedly installed on the outer circumferential surface of the turntable 4. The buffer assembly 8 includes a mounting base 801 fixedly installed to the inner side wall of the protective shell 1. A symmetrically arranged swing rod 802 is rotatably connected to the upper and lower ends of the mounting base 801. A roller 803 is rotatably connected to the end of the swing rod 802. The roller 803 rolls in contact with the outer circumferential surface of the annular cover 9. A tension spring 804 is provided on the opposite side of the two swing rods 802.

[0023] Slide rails 12 are fixedly installed on both sides inside the protective shell 1. The slide rails 12 are slidably connected to a sliding plate 10 located on the top of the protective shell 1. An electric push rod 11 is fixedly installed on the rear side of the top of the protective shell 1. The movable end of the electric push rod 11 is fixedly installed on the rear side of the sliding plate 10.

[0024] The turntable 4 is coaxially arranged with the output end of the drive motor 3. Multiple placement slots 5 are evenly distributed in the middle of the turntable 4. The distance between the center of the multiple placement slots 5 and the center of the turntable 4 is different. By setting multiple evenly distributed placement slots 5, the sample is placed in the placement tube 7. When different centrifugal forces are required to centrifuge the sample, the appropriate placement slot 5 can be selected according to the required centrifugal force and the distance between the placement slot 5 and the center of the rotating frame 6 and the turntable 4, so that it has different centrifugal forces. This allows for more precise control of the centrifugation degree of the soil sample, thereby improving the centrifugation efficiency of the soil sample and facilitating the control of the centrifugation degree of the sample.

[0025] A bracket is fixedly installed at the bottom inside the annular cover 9, and the bottom of the annular cover 9 is fixedly installed to the output end of the drive motor 3 through the bracket.

[0026] One end of the tension spring 804 is fixedly installed to the middle of a swing rod 802, and the other end of the tension spring 804 is fixedly installed to the middle of another swing rod 802. The two swing rods 802 are symmetrically arranged. By setting the buffer assembly 8, when the drive motor 3 drives the turntable 4 to rotate, the turntable 4 vibrates, causing the annular cover 9 to vibrate and tilt accordingly. By setting the two symmetrically arranged swing rods 802, when the annular cover 9 shakes in the horizontal direction, it squeezes the horizontal buffer assembly 8 on one side, which expands the angle between the two swing rods 802 and stretches the tension spring 804. Under the action of the tension spring 804, the swing rods 802 merge, pushing the inner shell to the initial middle position, thereby improving the stability of the protective shell 1 during use and reducing the loss caused by vibration.

[0027] The top of the protective shell 1 has an opening, which is located in the front half of the top of the protective shell 1. The width of the sliding plate 10 is greater than the width of the opening.

[0028] The bottom of the annular cover 9 is located above the fixed bracket 2, and the top of the annular cover 9 is flush with the top of the turntable 4.

[0029] Working principle:

[0030] When placing the sample in the placement tube 7, different centrifugal forces are required for centrifugation. According to the required centrifugal force, the appropriate placement slot 5 can be selected based on the placement slot 5 and the distance between the rotating frame 6 and the center of the turntable 4, so that different centrifugal forces are obtained, and the degree of centrifugation of the soil sample can be more accurately controlled. When the drive motor 3 drives the turntable 4 to rotate, the turntable 4 vibrates, causing the annular cover 9 to vibrate and tilt. By setting two symmetrically set swing rods 802, when the annular cover 9 shakes in the horizontal direction, it squeezes the horizontal buffer component 8 on one side, which expands the angle between the two swing rods 802 and stretches the tension spring 804. Under the action of the tension spring 804, the swing rods 802 merge and push the inner shell to the initial middle position, thereby improving the stability of the protective shell 1 during use and reducing the loss caused by vibration.
