Description

Technical Field

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

[0002] Soil environmental monitoring refers to determining environmental quality and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring is an abbreviation for soil environmental monitoring, which generally includes technical contents such as sampling, sample preparation, analytical methods, result characterization, data statistics and quality evaluation. In the process of soil testing, it is usually necessary to grind and crush the sampled soil for subsequent testing and analysis. Therefore, it is particularly important to develop a soil sample grinding device for soil testing.

[0003] A soil sample grinding device for soil testing, as described in reference announcement number CN220258237U, includes a grinding machine body. Inside the grinding machine body is a drive assembly with three sets of movable components evenly arranged on it. The drive assembly drives a rotating rod to rotate, which in turn drives the grinding blades to achieve the grinding effect. The upper side of the rotating rod is fixedly connected to two cleaning plates via a connecting plate. The cleaning plates are in contact with the inner wall of the grinding jar. When the rotating rod rotates, it drives the cleaning plates to clean the inner wall of the grinding jar, and a lower scraper cleans the bottom wall of the grinding jar. This device can prevent soil samples from sticking to the inner wall of the grinding jar when grinding highly viscous soil samples, making subsequent maintenance more convenient. However, while this device has good application potential, it is generally not convenient for sequential grinding of soil samples in two stations, making it difficult to achieve the expected grinding efficiency, which often troubles users. Utility Model Content

[0004] The purpose of this invention is to provide a soil sample grinding device for soil testing, in order to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to grind soil samples in two stations in sequence, making it difficult for the device to achieve the expected grinding efficiency of soil samples.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil sample grinding device for soil testing, comprising a machine base, a guide rail at the top of the machine base, two support platforms slidably mounted on the top of the guide rail, multi-section telescopic drive components mounted on the top of the machine base on both sides of the guide rail, one end of each multi-section telescopic drive component connected to the outer wall of the support platform, a component holder at the top of the support platform, a component holder with several strip-shaped dovetail grooves at the top, a base plate mounted at the center of the top of the component holder, a grinding frame at the top of the base plate, and a grinding cavity inside the grinding frame. The top of the body extends to the outside of the grinding frame. The top of the component seats on both sides of the substrate is provided with strip plates. An arc-shaped pressure plate is rotatably installed on the top of the strip plate. The lower surface of the arc-shaped pressure plate away from the strip plate touches the upper surface of the substrate. A dovetail internal thread block is movably installed inside the strip dovetail groove below the arc-shaped pressure plate. A locking bolt is installed on one side of the top of the arc-shaped pressure plate. The bottom end of the locking bolt passes through the arc-shaped pressure plate and is threaded to the top of the dovetail internal thread block. A control panel is installed on one side of the machine table surface. The output terminal of the microcontroller inside the control panel is electrically connected to the input terminal of the multi-section telescopic drive component.

[0006] Preferably, a base is provided on one side of the machine platform, and a column is provided at the center of the top of the base. A top seat is fixed to the top of the column to prevent the lifting frame from detaching from the outer wall of the column.

[0007] Preferably, a lifting frame is movably installed on the outer wall at the upper end of the column, and a limiting rail is provided on one side of the top of the lifting frame. The limiting rail is used to limit the movement range of the movable frame.

[0008] Preferably, a geared motor is installed on one side of the top of the base, and the top of the geared motor is provided with a threaded rod. The top of the threaded rod is rotatably connected to the bottom of the top seat, and the threaded rod is threadedly connected to the lifting frame. The geared motor is provided to drive the threaded rod to rotate.

[0009] Preferably, a movable frame is slidably mounted on the bottom end of the limiting rail, and an electric push rod is installed on the inner wall of one side of the lifting frame. The input end of the electric push rod is electrically connected to the output end of the microcontroller inside the control panel, and one end of the electric push rod is connected to the outer wall of the movable frame. The electric push rod is used to drive the movable frame to move horizontally.

[0010] Preferably, a roller frame is provided on the outer wall of the movable frame away from the electric push rod, and a grinding roller is rotatably installed at the bottom of the roller frame. The grinding roller is used to grind the soil sample inside the grinding chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the soil sample grinding device for soil testing not only improves the grinding efficiency of soil samples when the grinding device is used, but also achieves the purpose of easy and rapid grinding of soil samples, and makes it easy to quickly disassemble and replace the grinding frame, thereby improving the convenience of using the grinding device.

[0012] (1) The carrier platform is driven to slide on the top of the guide rail by the multi-section telescopic drive component, so that the carrier platform drives the grinding frame to move smoothly. Since there are two grinding frames, the two grinding frames can be moved to the bottom of the grinding roller in sequence, so that the soil sample can be ground in two stations in sequence. This can effectively reduce the downtime when loading and unloading the soil sample, thereby improving the grinding efficiency of the grinding device on the soil sample.

[0013] (2) By putting the soil sample into the grinding chamber, when the deceleration motor drives the threaded rod to rotate, the lifting frame slides down on the outer wall of the threaded rod and the column, so that the lifting frame drives the grinding roller to move down into the interior of the grinding chamber and contact the soil sample. Then, the electric push rod drives the movable frame to slide back and forth at the bottom of the limit rail, so that the movable frame drives the grinding roller to move back and forth, so that the grinding roller can grind the soil sample in the grinding chamber, thereby achieving the purpose of easy and rapid grinding of the soil sample.

[0014] (3) By tightening the locking bolt, the bottom end of the locking bolt is screwed out to the outside of the dovetail internal thread block. Then, the arc-shaped pressure plate is rotated so that one end of the arc-shaped pressure plate is turned away from the top of the substrate. At this time, the arc-shaped pressure plate no longer presses down on the substrate. The substrate can be pulled away from the top of the placement seat so that the grinding frame can be easily and quickly disassembled and replaced, thereby improving the convenience of using the grinding device.
