[0031] Specifically, the workbench 1 serves as the main frame of the entire device. The workbench provides a stable operating platform and is also the basis for installing various components. The bracket 2 is fixed to the left side of the top of the workbench 1 to provide support for the electric push rod 3 and the lifting plate 4 to ensure their stability and accuracy of vertical movement. There are two electric push rods 3 installed on the top of the bracket 2. The lifting plate 4 is driven up and down by telescopic movement to control the depth of the propeller blades 6. The motor 1 5 is installed on the top of the lifting plate 4 and is responsible for driving the propeller blades 6 to rotate for soil excavation and transportation. The conveying barrel 7 is fixed to the inner wall of the workbench 1 to receive the soil transported by the propeller blades 6 and guide the soil to the discharge port 22. The motor 2 9 is fixed to the left side of the screening box 8 to drive the disc 10 to rotate The disc 10 rotates, thereby driving the thin rod 11 and the push rod 13 to move, thereby realizing the vibration of the screen 15. The disc 10 is connected to the output end of the motor 29, and its rotational motion is transmitted to the push rod 13 through the thin rod 11. The thin rod 11 slides in the hollow shell 12, and converts the rotational motion of the disc 10 into a linear reciprocating motion. The hollow shell 12 fixes the push rod 13 and provides a sliding guide channel for the thin rod 11. The push rod 13 connects the thin rod 11 and the top block 14, and transmits the reciprocating motion of the thin rod 11 to the top block 14, thereby realizing the vibration of the screen 15. The screen 15 is installed in the screening box 8 for screening soil, so that qualified samples pass through the sieve mesh and fall into the collecting box 16. The classification box 21 is located on the right side of the screening box 8, and is used to collect large pieces of soil or other impurities that fail to pass through the screen 15.
[0032] Reference Figure 1 and Figure 3 The leveling assembly includes a screw 18, the bottom of the screw 18 is rotatably connected to the top of the support leg 20, the middle of the screw 18 is threadedly connected to a ball 17, the outside of the ball 17 is arranged inside the workbench 1, and the bottom of the ball 17 is fixedly connected to a telescopic rod 19.
[0033] Specifically, the screw 18 is the core component of the leveling assembly. The screw 18 is rotated manually, and its bottom is rotatably connected to the top of the support leg 20, allowing the screw 18 to rotate freely in the vertical direction. The rotation of the screw 18 can change the height of the ball 17, thereby adjusting the inclination angle of the workbench 1. The telescopic rod 19 is fixedly connected to the bottom of the ball 17, and its length can be adjusted as needed. The function of the telescopic rod 19 is to absorb or release energy through the change of its length when the ball 17 moves up and down, thereby helping the workbench to be smoothly adjusted to a horizontal state.
[0034] Reference Figure 1 - Figure 3A feed port 23 is fixedly connected to the top of the screening box 8, a discharge port 22 is fixedly connected to the right side of the conveying barrel 7, the discharge port 22 is arranged on the top of the feed port 23, a handle 1 24 is fixedly connected to the top of the screw 18, a handle 2 25 is fixedly connected to the front side of the collecting box 16, a limit block 26 is slidably connected to the outer side of the push rod 13, the left side of the limit block 26 is fixedly connected to the inner wall of the screening box 8, the left side of the hollow shell 12 is slidably connected to the right side of the disc 10, and the bottom of the telescopic rod 19 is fixedly connected to the top of the supporting leg 20.
[0035] Specifically, the feed port 23 is fixedly connected to the top of the screening box 8, serving as a passage for soil samples to enter the screening box. It is connected to the discharge port 22 of the conveying barrel 7 to ensure that the soil sample can be smoothly transferred from the conveying barrel 7 to the screening box 8 for screening. The discharge port 22 is fixed to the right side of the conveying barrel 7, located at the top of the feed port 23. Its function is to transport the sample excavated from the soil by the propeller blade 6 to the feed port 23 of the screening box 8 to achieve sample transmission. The handle 1 24 is fixedly connected to the top of the screw 18, providing the operator with a convenient hand-held part to facilitate rotating the screw 18 to adjust the level of the workbench 1. The handle 2 25 is fixed to the front side of the collection box 16, which is used to facilitate the operator to take out the collection box 16, so as to send the screened soil sample to the laboratory for testing. The limit block 26 is slidably connected to the outside of the push rod 13 and fixed to the inner wall of the screening box 8. Its function is to provide a limited range of movement for the push rod 13, to ensure that the movement trajectory of the push rod and the top block 14 during the screening process meets the design requirements, and to prevent damage or instability caused by excessive extension or contraction.
[0036] Working principle: When using this collection device to collect soil, place the device at the location to be sampled. If the ground is uneven and the device as a whole is not in a horizontal state, adjust the screw 18 in the corresponding tilting direction. The screw 18 rotates and drives the ball 17 to move upward. The ball 17 moves upward and drives a corner of the workbench 1 to lift upward, so that the workbench 1 remains horizontal to ensure the collection work. Then start the motor 5, so that the motor 5 drives the propeller blade 6 to rotate, so that the drill bit at the bottom of the propeller blade 6 rotates with it. At the same time, start the electric push rod 3, so that the electric push rod 3 drives the lifting plate 4 to move downward, so that the lifting plate 4 drives the motor 5 to move downward, so that the propeller blade is driven by the drill bit. 6 drills into the soil, so that the propeller blades 6 can transport the soil upward, so that the soil is transported to the inside of the conveying barrel 7 and to the discharge port 22. The soil falls into the feed port 23 at the top of the screening box 8 through the discharge port 22, and then falls onto the screen 15 through the feed port 23. At the same time, the motor 29 is started to drive the disc 10 to rotate, and at the same time drive the thin rod 11 to slide inside the hollow shell 12, and then drive the top block 14 to push the screen 15 up and down reciprocatingly through the push rod 13. Soil with a particle size that meets the requirements falls into the collection box 16 through the sieve mesh of the screen 15, while large pieces of soil that do not meet the requirements roll into the classification box 21 through the screen 15 without stopping. At this time, the screening is completed, and the soil in the collection box 16 can be taken out for inspection by pulling the handle 25.
