[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment 1:

[0025] Refer to Figure 1-7 , a device for mixing and removing impurities from forest soil samples, comprising: a mixing rack 1; a mixing box 3 rotatably connected to the mixing rack 1; wherein, a filter screen is provided on the side wall of the mixing box 3; a filter plate 4 connected to the mixing box 3; wherein, a filter screen 402 is provided on the filter plate 4, and the filter plate 4 is located on the central axis of the mixing box 3; a driving plate 303 fixedly connected to the inner wall of the mixing box 3; wherein, a discharge opening is provided at the lower end of the mixing rack 1;

[0026] When using this device, first place the soil sample to be de - impurities in the mixing box 3. At this time, rotate the mixing box 3, and the soil with smaller particles will fall from the discharge opening at the lower ends of the mixing box 3 and the mixing rack 1. And through the provided driving plate 303, the soil and impurities that have not fallen will be transported upward with the rotation. When the driving plate 303 is inclined downward, these soil and impurities will fall on the filter plate 4. After being filtered again, the impurities remain on the filter plate 4, and the soil falls to the bottom of the mixing box 3 and enters the discharge opening after being filtered again;

[0027] It should be noted that when the soil moves with the rotation of the driving plate 303, the soil will automatically roll, which can mix the soil, and the mixing and filtering - impurity - removing effects are better.

[0028] A guide shaft 102 is fixedly connected to the mixing rack 1, and the filter plate 4 is slidably connected to the guide shaft 102. The guide shaft 102 is arranged in a straight - line shape;

[0029] By arranging the guide shaft 102 in a straight - line shape, the filter plate 4 can only slide on the guide shaft 102.

[0030] A driving motor 5 is provided at the upper end of the mixing rack 1. The output end of the driving motor 5 is fixedly connected to the driving gear 502, and a driven gear 501 is provided on the mixing box 3. The driven gear 501 meshes with the driving gear 502;

[0031] When starting the drive motor 5, the driven gear 501 can be driven to rotate by the driving gear 502, thereby realizing the drive of the mixing box 3.

[0032] A return spring 401 is fixedly connected to the side of the filter plate 4, and the other end of the return spring 401 is fixedly connected to the mixing frame 1. Driven wedges 403 are symmetrically arranged on the same side of the filter plate 4. A drive shaft 302 is provided on the mixing box 3, and the drive shaft 302 is matched with the driven wedges 403.

[0033] When the mixing box 3 rotates, it will synchronously drive the drive shaft 302 to rotate. When the drive shaft 302 contacts the driven wedges 403, the driven wedges 403 will drive the filter plate 4 to slide. At the same time, the set return spring 401 can pull the filter plate 4 back to its original position when the drive shaft 302 separates from the driven wedges 403. That is, when the mixing box 3 rotates, it will synchronously drive the filter plate 4 to slide back and forth on the guide shaft 102, thereby realizing the screening of soil and impurities on the filter plate 4 and promoting the soil to fall from the filter net 402.

[0034] An external feeding port 101 is provided on the mixing frame 1, and a plurality of groups of internal feeding ports 301 are opened on the side wall of the mixing box 3. By providing the external feeding port 101 and the internal feeding ports 301, it is convenient to add the soil to be mixed and decontaminated into the mixing frame 1. And a plurality of groups of internal feeding ports 301 are provided, which are suitable for different stopping positions after the mixing box 3 rotates.

[0035] A collection box 2 is provided at the discharge opening of the mixing frame 1, which is convenient for collecting the mixed soil that falls at the discharge opening.

[0036] A side frame door 103 is detachably connected to the mixing frame 1. Specifically, the detachable connection method is by bolts. The side frame door 103 penetrates through one side of the mixing box 3, and the guide shaft 102 is inserted into the side frame door 103.

[0037] When the side frame door 103 is removed, it is convenient to take out the impurities filtered on the filter plate 4.

[0038] By setting the rotating mixing box 3 and the reciprocating sliding filter plate 4, the present utility model can filter and remove impurities in the soil while mixing the soil, thereby improving the processing speed of soil samples.

[0039] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, should be covered by the protection scope of the present utility model.
