The lower side of the brush 12 and the upper surface of the sieve body 5 contact.
[0043] First, the preparation of the device. Find the bottom support plate body 1, as the foundation of the entire device support components, stable placed on the operating plane, to ensure that it is placed stable, not shaking or tilting. Observe the upper edge of the bottom support plate body 1, can see the fixed core support plate body 2, core support plate body 2 to the middle of the bottom support plate body 1 upwards, its structure is firm, reliable connection support for subsequent components.
[0044] Next, look at the upper end of the core support plate body 2, here fixed with a circular placement tube 3, circular placement tube 3 in the overhead direction presents a regular circle, its design is conducive to the installation and cooperation of subsequent components. Note that the circular placement tube 3 is provided with a vertical notch 4, the opening of the vertical notch 4 is upward, and the lower part is located in the middle of the lower part of the circular placement tube 3, there are four of them, which are evenly distributed around the axis of the circular placement tube 3, these vertical notches 4 play a key role in the process of stable and cooperation of the device.
[0045] Then, prepare the sieve body 5, the opening direction of the sieve body 5 is upward, and it presents a circular shape in the overhead direction, which is adapted to the structure of the entire device. The middle part is provided with a circular ring body 6, and the circular ring body 6 is provided with a core cross-shaped plate body 7. The lower side of the core cross-shaped plate body 7 is fixedly provided with a cylindrical block 8. Carefully put the circular ring body 6 into the circular placement tube 3, so that the core cross-shaped plate body 7 accurately passes through the vertical notch 4 on the circular placement tube 3. At this time, the inner wall of the circular ring body 6 is in close contact with the outer wall of the circular placement tube 3, so as to ensure that the sieve body 5 can be stably placed in the correct position during the operation of the device.
[0046] Then, introduce the motor 9, and the lower part of the motor 9 is provided with an auxiliary cross-shaped plate body 10. The motor 9 also presents a circular shape in the overhead direction. Observe the output shaft of the motor 9, which is provided with a plurality of auxiliary arms 11. The auxiliary arms 11 are evenly distributed around the output shaft of the motor 9, and the lower end of each auxiliary arm 11 is fixedly provided with a brush 12. The extension direction of the brush 12 is designed to pass through the axis of the output shaft of the motor 9, so as to work efficiently during operation. Install the motor 9 into the circular placement tube 3, so that the outer wall of the motor 9 cooperates with the inner wall of the circular placement tube 3, and the auxiliary cross-shaped plate body 10 also passes through the vertical notch 4 on the circular placement tube 3. At this time, the lower part of the motor 9 is located on the upper side of the core cross-shaped plate body 7, and the lower side of the brush 12 is in close contact with the upper surface of the sieve body 5, so as to ensure that the subsequent screening action can be smoothly carried out.
[0047] After everything is ready, enter the use link. First, the dry agricultural soil is carefully placed in the sieve body 5, pay attention to the amount of loading, avoid overload affecting the screening effect. Then, take the collection basin and place it stably on the bottom support plate body 1, and make sure that the collection basin is located below the sieve body 5, the position is accurate, so as to effectively collect the small particles falling off.
[0048] Finally, start the motor 9 through the external device, the external device needs to be correctly connected and operated according to the rated parameters of the motor 9. After the motor 9 is started, the auxiliary arm 11 on the output shaft is driven to rotate at high speed, and then the brush 12 is quickly swept on the upper surface of the sieve body 5, the brush 12 is in close contact with the sieve body 5, and the agricultural soil in the sieve body 5 is constantly disturbed, so that finer particles can pass through the screen of the sieve body 5 and fall into the collection basin below, efficiently completing the soil screening work and meeting the requirements of the preliminary treatment for accurate detection of soil composition.
[0049] Firstly, the overall structure design of the device fully considers the convenience of installation and disassembly. The connection between each part is simple and reasonable, for example, the bottom support plate body 1 and the core support plate body 2 are fixedly connected, which not only ensures the stability of the structure, but also is easy to quickly form during production and assembly. The installation of the sieve body 5 is even better, which is realized by the cooperation of the circular ring body 6 and the circular placement pipe body 3, and the core cross-shaped plate body 7 passes through the vertical gap 4 on the circular placement pipe body 3 to realize accurate positioning. When disassembling, you only need to operate in the opposite direction, and the sieve body 5 can be easily removed. This convenient disassembly feature brings great practical value. After disassembly, the sieve body 5 can be cleaned in all directions without dead angles, effectively avoiding the influence of soil residue accumulation on the subsequent screening accuracy, and ensuring that the device can maintain the best working state every time it is used.
[0050] Secondly, the motor 9 and the brush 12 provided bring a qualitative leap to the screening work. The motor 9, as a power source, drives the output shaft to rotate at high speed, and then drives the brush 12 to quickly sweep on the upper surface of the sieve body 5. Compared with the traditional method of relying on natural gravity or simple shaking for screening, the continuous disturbance of the brush 12 can break the adhesion between the soil particles, disperse the agglomerated particles that may block the screen, and give more opportunities for finer particles to pass through the screen. In this way, not only the efficiency of screening is greatly improved, the time cost of screening is reduced, but also the effect of screening is significantly improved, the particle size of the screened soil sample is more uniform, the accuracy is higher, which provides a reliable guarantee for the subsequent accurate detection of soil composition, and meets the needs of high-quality soil samples in agricultural research, soil improvement and other fields.
[0051] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
