[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model proposes a soil sample screening device, including a screening mechanism formed by stacking and combining several screen bodies 1. A top cover 2 is installed on the uppermost screen body 1 of the screening mechanism. The combination of the screening mechanism and the top cover 2 is fixedly installed on a vibrating table. The vibrating table used for screening materials is prior art, so it will not be described in detail and is not shown in the drawings. A mounting groove 1014 for mounting a sealing slide plate 102 is opened on the side wall of the screen frame 101 of the screen body 1. A through-type discharge port 1013 is opened on the side wall of the screen frame 101 at the mounting groove 1014. The slide rod 1022 on the sealing slide plate 102 passes through the slide groove 1015 and extends to the outside to be threadedly connected to the limiting nut 103. A rubber anti-slip pad 104 is installed between the limiting nut 103 and the outer wall of the screen frame 101.

[0025] When using the equipment, select the appropriate aperture size of the sieve body 1 according to the actual needs, stack them together, and install them on the vibrating table. Then, put the soil sample to be screened into the top sieve body 1, cover it with the top cover 2, and turn on the vibrating table. The vibrating table will vibrate the screening mechanism installed on it. During the vibration, the screening mechanism will complete the screening of the soil sample. Finally, remove the screening mechanism from the vibrating table, move it to the designated material collection position, and then take out the soil sample retained in each sieve body 1 one by one from top to bottom or from bottom to top.

[0026] When removing the soil sample retained in sieve body 1, loosen the limiting nut 103 on the corresponding sieve body 1. Then, through the cooperation of the limiting nut 103 and the slide rod 1022, push the sealing slide plate 102 to slide in the placement groove 1014 to open the discharge port 1013. Then, tilt the sieve body 1 towards the discharge port 1013 to pour out the soil sample retained in the sieve body 1. After completion, reset the sealing slide plate 102 and screw in the limiting nut 103 to fix the sealing slide plate 102 in place. Repeat the above operation to complete the removal of soil samples retained in multiple sieve bodies 1. Thus, after the drying process is completed, there is no need to disassemble each sieve body 1. The soil sample after sieving can be quickly removed. It is fast, efficient, simple and convenient to use.

[0027] like Figure 1 As shown, in some embodiments, the sieving mechanism formed by stacking and assembling sieve bodies 1 has a gradually smaller screen aperture from top to bottom. The screen is fixedly connected to the sieve frame 101. The lowest sieve body 1 of the sieving mechanism does not have a screen and a material support plate is installed at the bottom of the sieve frame 101 to facilitate the sieving process of soil samples, so that different particle sizes in the soil samples are separated. The lowest sieve body 1 does not have a screen but has a material support plate installed, which facilitates the collection and concentration of the last sieved soil sample, thereby completing the sieving process of the soil sample.

[0028] like Figure 1 and Figure 4 As shown, in some embodiments, the connecting slot 1011 at the upper port of the sieve frame 101 is configured to cooperate with the connecting ring plate 1012 at the lower part of the sieve frame 101. This facilitates the arrangement of each sieve body 1 according to the size of the sieve mesh, with the mesh size gradually decreasing from top to bottom, by utilizing the cooperation between the connecting slot 1011 and the connecting ring plate 1012. The sieve bodies are stacked and combined one by one to form a stable sieving mechanism, thereby sieving soil samples. The top cover 2 is provided with an annular connecting plate that cooperates with the connecting slot 1011, which facilitates the stable installation of the top cover 2 on the sieving mechanism, ensuring stable use.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, half the length of the placement groove 1014 on the screen frame 101 is greater than the length of the blocking slide plate 102. The blocking slide plate 102 is slidably connected in the placement groove 1014, and the slide groove 1015 located above the discharge port 1013 is in communication with the placement groove 1014.

[0030] The lengths of the placement groove 1014 and the blocking slide plate 102 are designed to allow the blocking slide plate 102 to be stored in the placement groove 1014 at the part where the discharge port 1013 is not located when the discharge port 1013 is opened, so that the discharge port 1013 can be opened smoothly. When the discharge port 1013 needs to be closed, the blocking slide plate 102 only needs to be pushed to slide in the placement groove 1014, so that it moves to the position of the placement groove 1014 where the discharge port 1013 is located, so that the discharge port 1013 can be stably blocked.

[0031] like Figure 2 and Figure 3As shown, in some embodiments, the slider 1021 on the blocking slide plate 102 is slidably connected in the slide groove 1015. The cooperation between the slider 1021 and the slide rod 1022 on the blocking slide plate 102 and the slide groove 1015 improves the stability of the blocking slide plate 102 sliding in the placement groove 1014, ensuring smooth completion of the position adjustment operation of the blocking slide plate 102, and realizing the opening and closing operation of the discharge port 1013 on the screen frame 101. After opening the discharge port 1013, the direction towards the discharge port 1... The 013-direction tilting screening mechanism can pour out the soil samples trapped in each sieve body 1, quickly completing the removal operation of the soil samples after screening. The slide rod 1022 on the sealing slide plate 102 is provided with a threaded section that matches the limiting nut 103 on the rod body outside the slide groove 1015, which makes it easy to stably install the limiting nut 103 onto the slide rod 1022 and abut against the sieve frame 101 during the screwing process, fixing and limiting the sealing slide plate 102 to ensure stable use.

[0032] The rubber anti-slip pad 104 has a through-hole for inserting the slide rod 1022 in the middle part, which facilitates the smooth installation of the rubber anti-slip pad 104 onto the slide rod 1022 and ensures stable use. The side of the rubber anti-slip pad 104 that is in contact with the outer wall of the screen frame 101 is provided with evenly distributed anti-slip ridges to increase the frictional resistance between the two and achieve stable fixed positioning. During use, it cooperates with the limit nut 103 to ensure stable and effective positioning and fixing of the sealing slide plate 102.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
