Example

[0015] Please see Figure 1-7 The present invention provides the following technical solution: an improved soil sample collection device, including a collection box 1, with side protrusions 2 integrally connected to the upper left and right sides of the collection box 1, and a plurality of cavities 3 opened inside the collection box 1. The cavities 3 are evenly distributed and have a conical structure. The bottom sides of the cavities 3 are provided with discharge ports 4. The side protrusions 2 facilitate the handling and movement of the device. Reference Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, further, an opening 5 is provided in the middle of the discharge port 4. A bracket 6 is fixedly connected to the upper end of the cavity 3. An opening 7 is provided in the middle of the bracket 6. A rotating shaft 8 is rotatably connected inside the opening 7. A knob 9 is fixedly connected to the uppermost end of the rotating shaft 8. The bottom end of the rotating shaft 8 is rotatably connected to the opening 5, and a discharge plate 10 is fixedly connected to the bottom end of the rotating shaft 8. Discharge ports 11 are provided on both the left and right sides of the discharge plate 10. Both the discharge port 4 and the discharge port 11 are arc-shaped structures and are symmetrically distributed from left to right. When in use, the rotating shaft 8 inside the cavity 3 is rotated clockwise or counterclockwise by the knob 9, thereby driving the discharge plate 10 at the bottom of the cavity 3 to rotate. When the discharge port 2 11 on the discharge plate 10 is connected to the discharge port 1 4, the soil sample in the cavity 3 can fall out through the discharge port 1 4 and the discharge port 2 11 and further fall into the mixing box 17. When the discharge port 2 11 and the discharge port 1 4 are completely misaligned, the discharge port 1 4 at the bottom of the cavity 3 is closed and the soil sample is no longer discharged. The soil sample is in granular form after grinding. Reference Figure 1 and Figure 2 As shown, furthermore, support legs 12 are fixedly connected to the bottom of the collection box 1 around all four sides, support feet 13 are fixedly connected to the bottom of the support legs 12, support pads 14 are glued to the bottom of the support feet 13, and the support pads 14 are rubber components. A limiting bracket 15 is fixedly connected to the inner bottom of the support legs 12, and the limiting bracket 15 has an "L" shaped structure. A limiting top frame 16 is fixedly connected to the inner upper end of the support legs 12, and a mixing box 17 is engaged between the limiting bracket 15 and the limiting top frame 16. The support legs 12 with support pads 14 and support feet 13 are used to support the raising of the collection box 1, so as to further set up the mixing box 17. The limiting bracket 15 and the limiting top frame 16 are used to limit the placement of the mixing box 17 at the bottom of the collection box 1, and the collection box 1 can be pulled out. Reference Figure 1 and Figure 2 As shown, a stirring motor 18 is fixedly installed at the middle of the bottom of the mixing box 17, and a stirring frame 19 is fixedly connected to the output end of the stirring motor 18. The stirring motor 18 and the stirring frame 19 are used to further stir and mix the various soil samples in the mixing box 17.

[0016] In this embodiment: the present invention facilitates the collection of various soil samples through several discharge ports 4 in the collection box 1. When preparing a mixture of various soil samples, the discharge plate 10 at the bottom of the cavity 3 can be rotated by the knob 9 and the rotating shaft 8 in the cavity 3 to control the opening and closing of the discharge ports 4 at the bottom of the cavity 3, thereby controlling the discharge of soil samples in the cavity 3, so that various soil samples can be added to the mixing box 17. The operation is simple and convenient, which facilitates the preparation of a mixture of various soil samples. Then, the various soil samples falling into the mixing box 17 can be stirred and mixed by the stirring plate motor 18 and the stirring rack 19, which effectively solves the problems of the prior art.

[0017] The usage process and working principle of this utility model are as follows: In use, an external power supply is used to start the stirring motor 18. The stirring motor 18 drives the mixing rack 19 inside the mixing box 17 to rotate. Then, the rotating shaft 8 inside the cavity 3 can be rotated clockwise or counterclockwise using the knob 9, thereby driving the discharge plate 10 at the bottom of the cavity 3 to rotate. When the discharge port 11 on the discharge plate 10 is connected to the discharge port 4, the soil sample inside the cavity 3 can fall out through the discharge port 4 and the discharge port 11 and further fall into the mixing box 17. When the discharge port 11 is connected to the discharge port 4, the soil sample inside the cavity 3 can fall out through the discharge port 4 and the discharge port 11 and further fall into the mixing box 17. When the material inlet 11 and the discharge outlet 4 are completely offset, the discharge outlet 4 at the bottom of the cavity 3 is closed, and the soil sample is no longer discharged. It should be noted that the soil sample is in granular form after grinding. At the same time, the various soil samples falling into the mixing box 17 are further stirred and mixed by the stirring plate motor 18 and the stirring rack 19, thereby completing the preparation of the mixture of various soil samples. Finally, the mixing box 17 is pulled out, and the mixed sample in the mixing box 17 can be further removed for subsequent testing operations.
