Description

Technical Field

[0001] This utility model relates to the field of soil composition analysis technology, specifically a soil mechanical composition analysis data acquisition device with early warning function. Background Technology

[0002] Soil mechanical composition refers to the combination ratio of mineral particles of different sizes in the soil. It has a crucial impact on the physical properties of the soil, fertility status, and crop growth. Accurately obtaining soil mechanical composition data and timely issuing early warnings based on data changes are of great significance for agricultural production, land resource management, and ecological environmental protection. Therefore, data acquisition devices are required for this purpose.

[0003] Existing data acquisition devices have certain shortcomings in use. They are cumbersome to operate, time-consuming and labor-intensive, and have extremely low experimental efficiency, causing great inconvenience to scientific research. There is an urgent need for improvement to facilitate the analysis and determination of soil particles. To solve the above problems, an automated soil particle analysis device disclosed in application (application number CN201510622007.1) can be referred to. This device uses a single-chip microcomputer in the control box to control the stepper motor, rack, gear and support rod to complete the experimental process of liquid absorption, liquid release, rinsing and liquid discharge, and feeds back to the host computer to accurately control the sampling time and accurately determine the soil particles.

[0004] Although the above-mentioned device can solve the problem of cumbersome operation procedures, it still has some shortcomings in use. When detecting the content of different components, it is necessary to avoid soil particles from clogging the inside of the screen. Therefore, the screen needs to be shaken. However, the above-mentioned device lacks the ability to prevent soil particles from clogging the inside of the screen, which leads to inaccurate data collection and processing.

[0005] Therefore, we proposed a soil mechanical composition analysis data acquisition device with early warning function, which can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a soil mechanical composition analysis data acquisition device with an early warning function, in order to solve the problem mentioned in the background art that current data acquisition instruments on the market need to avoid soil particles clogging the inside of the screen when detecting the content of different components. Therefore, the screen needs to be shaken. However, the above-mentioned device lacks the ability to prevent soil particles from clogging the inside of the screen, which leads to inaccurate data collection and processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil mechanical composition analysis data acquisition device with early warning function, including a fixed frame and a feeding box for feeding. A display assembly is fixed to the side of the fixed frame; a servo motor is fixedly installed at the bottom of the fixed frame, and the output end of the servo motor is fixed to one side of a shaking screen mechanism. The movement of the shaking screen mechanism drives multiple sets of screen components to move back and forth at the upper end of the fixed frame; the screen components are limited inside two sets of fixed plates, and an air blowing mechanism is provided at the rear of the fixed plates. The air blowing mechanism prevents soil residue from occurring inside the feeding box.

[0008] As a preferred technical solution of this application, the screen components are arranged in five groups. The screen apertures of the uppermost screen component to the second-to-last screen component are 2mm, 1mm, 0.5mm, 0.25mm and 0.1mm respectively. The lowermost screen component is a tray. The outer wall dimensions of the five groups of screen components are the same. In addition, the lowermost screen component does not contact the top of the fixing frame.

[0009] As a preferred technical solution of this application, the shaking screen mechanism includes a turntable fixed at the output end of a servo motor. The top center of the turntable is rotatably disposed at the bottom of a fixed frame. A set of connecting rods is rotatably connected to the bottom edge of the turntable. The outer ends of the connecting rods are rotatably disposed at the bottom of a fixed plate. The bottom of the fixed plate is slidably disposed in a groove that is opened through the inside of the fixed frame.

[0010] As a preferred technical solution of this application, the fixing plate and the slide are symmetrically arranged in two sets about the transverse center line of the fixing frame, and five sets of limiting mechanisms are fixed on the inner side of the two sets of fixing plates.

[0011] As a preferred technical solution of this application, the limiting mechanism includes a rotating screw rotatably disposed on the inner side of the fixed plate. The outer side of the rotating screw is threadedly connected to the inner side of the moving protrusion, and the outer side of the rotating screw is rotatably disposed on the inner side of the fixed protrusion. The protrusion positions of the moving protrusion and the fixed protrusion are both embedded in the interior of the screen component.

[0012] As a preferred technical solution of this application, the air blowing cleaning mechanism includes two sets of fixing rods fixed to the rear side of the fixing plate. A piston block is fixed at the end of the fixing rod. The outer side of the piston block is attached to the inside of the fixing cylinder. In addition, the bottom of the fixing cylinder is fixed to the inside of the fixing frame. An air supply pipe is connected to the side of the fixing cylinder away from the fixing rod. The top end of the air supply pipe extends into the inside of the feeding box.

[0013] As a preferred technical solution of this application, a one-way air inlet valve is provided on the side of the fixed cylinder near the air supply pipe, and a one-way air inlet valve is provided inside the air supply pipe. The end of the air supply pipe that extends into the material box is inclined downwards.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This soil mechanical composition analysis data acquisition device with early warning function is equipped with a shaking screen mechanism. Through the operation of the shaking screen mechanism, multiple sets of screens can be shaken and screened on the top of the fixed frame, thereby preventing soil particles from remaining on the top of the screens. The operation of the air blowing mechanism can clean and discharge the particles remaining inside the feeding box. The specific details are as follows: 1. A servo motor is installed. The rotation of the servo motor drives the turntable to rotate, which causes the connecting rod to move the fixed plate back and forth inside the slide groove. This causes the screen between the two sets of fixed plates to shake back and forth, thus preventing soil and mud from clogging the surface of the screen. Furthermore, a rotating screw is installed. The rotation of the screw causes the threaded moving protrusion to fit tightly against the concave position of the screen, thereby fixing the screen and facilitating the shaking screen process.

[0015] 2. A fixing rod is installed. By moving the fixing plate, the fixing rod and piston block can slide inside the fixing cylinder, so that the gas inside the gas delivery pipe is delivered to the inside of the feeding box, which can prevent soil particles from remaining inside the feeding box.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figures 1-8 The present invention provides the following technical solution: Example

[0020] To address the issue of soil particles clogging the screen when current data acquisition instruments detect different component contents, a shaking process is needed. However, the aforementioned device lacks this feature to prevent soil particles from clogging the screen, thus hindering accurate data collection and processing. Please refer to the attached document. Figure 1 -Appendix Figure 5 and attached Figure 8The system includes a fixed frame 1 and a feeding box 2 for feeding materials. A display assembly 3 is fixed to the side of the fixed frame 1. A servo motor 4 is fixedly installed at the bottom of the fixed frame 1. The output end of the servo motor 4 is fixed to one side of the shaking screen mechanism. The movement of the shaking screen mechanism drives multiple sets of screen components 12 to move back and forth at the upper end of the fixed frame 1. There are five sets of screen components 12. The screen apertures of the top screen component 12 to the second-to-last screen component 12 are 2mm, 1mm, 0.5mm, 0.25mm and 0.1mm respectively. The bottom screen component 12 is a tray. The outer wall dimensions of the five sets of screen components 12 are the same. In addition, the bottom screen component 12 does not contact the top of the fixed frame 1. The shaking screen mechanism includes a rotating... The top center of the turntable 5 is rotatably mounted at the bottom of the fixed frame 1. A set of connecting rods 6 are rotatably connected to the bottom edge of the turntable 5. The outer end of the connecting rods 6 is rotatably mounted at the bottom of the fixed plate 7. The bottom of the fixed plate 7 is slidably mounted in the sliding groove 8 that runs through the inside of the fixed frame 1. Two sets of fixed plates 7 and sliding grooves 8 are symmetrically arranged about the transverse center line of the fixed frame 1. Five sets of limiting mechanisms are fixed on the inner side of the two sets of fixed plates 7. The limiting mechanism includes a rotating screw 11 rotatably mounted on the inner side of the fixed plate 7. The outer side of the rotating screw 11 is threadedly connected to the inner side of the moving protrusion 10. The outer side of the rotating screw 11 is rotatably mounted on the inner side of the fixed protrusion 9. The protrusions of the moving protrusion 10 and the fixed protrusion 9 are both embedded in the inside of the screen component 12.

[0021] Before using the device, representative soil samples are collected within the study area according to certain sampling principles. Multiple samples are typically combined into a single sample. Stones, plant debris, and other impurities are removed from the soil sample. The collected soil samples are then air-dried indoors or dried in an oven at 40-50°C to prevent changes in soil particle properties due to high temperatures. The dried soil sample is then placed in a mortar and gently ground with a pestle to thoroughly break it down. The broken soil is weighed using the weighing module of the display assembly 3. The crushed soil sample is then placed into the feeding box 2, and multiple sets of screens 12 are placed on top of the fixing protrusions 9. By rotating the screw 11, the threaded moving protrusions 10 engage with the top position of the screens 12, thus fixing the multiple sets of screens 12. The sieveable soil particles are then collected and processed. The process is then initiated by activating the lower part of the fixing frame 1. After the servo motor 4 is fixed, when the feeding port of the feeding box 2 is opened, the output end of the servo motor 4 can drive the fixedly connected turntable 5 to rotate during operation, thereby causing the connecting rod 6, which is rotated and set at the lower edge of the turntable 5, to move. This allows the connecting rod 6 to drive the rotating fixed plate 7 to move back and forth through the slide groove 8. At this time, the screen 12 fixed inside the fixed plate 7 can be shaken and screened, thereby preventing soil particles of different sizes from falling into different surface positions of the screen 12. By collecting the soil at the top of the screen 12, the particles collected at the top of multiple sets of screen 12 are weighed by the weighing module of the display assembly 3. When the obtained data is greater than the set content, the warning module will display it through the display module. Finally, the percentage content of particles of each particle size will be obtained through the display module of the display assembly 3. Example

[0022] To prevent residue from remaining inside the feeding hopper 2 during material feeding, please refer to the attached document. Figure 1 -Appendix Figure 3 Appendix Figure 6 and attached Figure 7 The screen component 12 is confined within the two sets of fixed plates 7, and an air blowing mechanism is provided at the rear side of the fixed plates 7. The air blowing mechanism prevents soil residue from remaining inside the feed box 2. The air blowing cleaning mechanism includes fixed rods 13 fixed to the rear side of the two sets of fixed plates 7. A piston block 14 is fixed to the end of the fixed rod 13. The outer side of the piston block 14 is attached to the inside of the fixed cylinder 15. The bottom of the fixed cylinder 15 is fixed to the inside of the fixed frame 1. An air supply pipe 16 is connected to the side of the fixed cylinder 15 away from the fixed rods 13. The top end of the air supply pipe 16 extends into the inside of the feed box 2. A one-way air inlet valve is provided on the side of the fixed cylinder 15 near the air supply pipe 16. A one-way air inlet valve is also provided inside the air supply pipe 16. The end of the air supply pipe 16 that extends into the feed box 2 is inclined downwards. When the shaking screen mechanism moves back and forth, the two sets of fixed plates 7 also move synchronously in the same direction, causing the fixed rod 13 at the rear of the fixed plate 7 to drive the piston block 14 to move. This causes the piston block 14 to move back and forth inside the fixed cylinder 15. Subsequently, the gas inside the fixed cylinder 15 will be continuously charged through the one-way air inlet valve, and the gas will be delivered to the inside of the air supply pipe 16 through the one-way air outlet valve. This allows the top of the air supply pipe 16 to continuously supply air to the inside of the feeding box 2, preventing soil from adhering to the inner wall of the feeding box 2.
