Description

Technical Field

[0001] This utility model relates to the technical field of grinding equipment for soil testing, specifically a rapid grinding and processing device for soil testing samples. Background Technology

[0002] Soil testing is a fundamental step in fields such as arable land quality assessment, pollution control, and agricultural research. Soil sample grinding is a core pretreatment step before testing; the particle size uniformity and purity of the ground sample directly determine the accuracy of subsequent heavy metal content analysis, nutrient detection, and other data. Modern soil testing places stringent requirements on pretreatment processes, demanding high throughput, low pollution, and high adaptability. This is especially true for precision detection technologies such as microwave digestion, which require sample particle size control below 75-150 μm. Otherwise, insufficient dissolution of target elements, significant deviations in detection data, and even safety risks during the digestion process may occur. However, traditional grinding equipment mostly uses a single grinding structure and does not have a specific crushing and pretreatment mechanism. When dealing with soil samples containing large clumps collected in the field, manual crushing or sieving is required in advance, which is cumbersome and time-consuming. When directly put into grinding, large soil clumps can easily cause the grinding rollers to jam and wear. Moreover, repeated impacts are required during the grinding process to break them up, resulting in low grinding efficiency. Utility Model Content

The guide rod is fixedly connected to the top surface of the base plate, and two sets of guide rods are provided. The moving plate is slidably connected between the two sets of guide rods. The first and second support rods are both fixedly connected to the top surface of the moving plate, and two sets of both support rods are provided. The mounting plate is fixedly connected to the top surface of the base plate. The telescopic cylinder is fixedly installed on the back of the mounting plate, and the output end of the telescopic cylinder is fixedly connected to the moving plate.

[0006] Furthermore, the grinding mechanism includes an inclined tube, a grinding roller, a grinding plate, a motor, a material trough, and a baffle. The inclined tube is fixedly connected between two sets of support rods. The grinding roller is rotatably connected inside the inclined tube.

An air outlet is provided on the front side of the inclined tube. The toothed pulley is fixedly connected to the grinding roller through a transmission rod.

[0007] Furthermore, the crushing mechanism includes a top box, a pressure frame, tension springs, an outer cylinder, a sliding rod, a force-bearing plate, a vertical plate, a rotating rod, an eccentric block, and a rotating wheel. The top box is fixedly connected to the inclined tube, and the pressure frame is slidably connected inside the top box.

The force-bearing plate is fixedly connected to the top end of the sliding rod. The vertical plate is fixedly connected to the top surface of the top box. The rotating rod is rotatably connected to the vertical plate through a bearing. The eccentric block is fixedly connected to the rotating rod, and the rotating wheel is rotatably connected to the inner side of the eccentric block. The toothed pulley is fixedly connected to the end of the rotating rod away from the eccentric block.

[0008] Furthermore, a water tank is fixedly connected to the bottom of the base plate, a water pipe is fixedly connected to the back of the water tank, and a filter frame is fixedly connected inside the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses toothed pulley one, toothed pulley two, and a toothed belt to transmit the rotational power of the grinding roller to the rotating rod. The rotating rod drives the eccentric block to rotate, causing the roller to press against the force plate. This allows the pressure frame to crush larger soil clods entering the inclined tube. The crushed soil clods are then easier for the grinding roller to rotate and grind, thus improving the grinding efficiency of the equipment. A telescopic cylinder drives the moving plate to move backward along the guide rod, allowing the grinding mechanism to move backward synchronously and align the bottom of the inclined tube with the through groove. Simultaneously, the material trough aligns with the mounting frame one. A water pump can then extract water from the water tank. The system sprays water into the material trough through nozzles to rinse it. When water flows into the inclined tube, the motor is activated to rinse the inclined tube, grinding roller, grinding plate, and pressure frame with clean water. After rinsing, the fan is started and the heating wire is energized, so that the air blown by the fan is heated by the heating wire and blown into the material trough and the inclined tube, thereby quickly drying the material trough, inclined tube, grinding roller, grinding plate, and pressure frame. After drying, the grinding mechanism is reset to continue grinding the next batch of soil. This device can quickly clean and dry the grinding mechanism, thus enabling rapid grinding of multiple batches of soil. Attached Figure Description

After rinsing, the heating wire 20 is energized and heated. At the same time, the blower 22 is started. The gas blown out by the blower 22 is heated by the heating wire 20 and enters the material trough 45 and the inclined tube 41 to dry the material trough 45, the inclined tube 41 and the parts inside them. After drying, the grinding mechanism 4 is reset forward to start the next batch of soil grinding.
