Description

Technical Field

[0001] The utility model relates to the technical field of sifters, in particular to a soil sifter for soil detection. Background Art

[0002] Soil refers to a loose layer of material on the surface of the earth. In order to filter the soil particles to a size suitable for further analysis, a soil sifter is a device that sieves the soil and then sends the sieved soil for testing.

[0003] The Chinese patent with the patent number CN212576488U discloses a soil sifter for soil detection, which includes a base and a sifting box. A sifting cavity is provided inside the sifting box. Three rectangular frames are distributed up and down in the sifting cavity.

[0004] Although the above patent uses a screen to screen the soil during use; during the reciprocating movement of the screening box, the soil can be broken up by the crushing teeth, so that the soil is loosened and not easily accumulated and blocked in the folded feed port. The screened soil will flow out from the discharge port, but the soil with large particles will remain on the screen. To remove the soil on the screen, it is necessary to dismantle it, which makes the removal of the soil retained on the screen more cumbersome. Therefore, a new type of soil screener for soil testing is urgently needed to solve these problems. Utility Model Content

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] In order to solve the problem that during the use of the existing soil screener for soil testing, the screened soil will flow out from the discharge port, but the soil with large particles will remain on the screen. The screen needs to be removed to remove the soil, which makes it more cumbersome to remove the soil retained on the screen. The utility model uses a limit block set on the side wall of the screening box. The fixing bolt can fix the screening plate and the bearing seat together, so as to avoid the connecting shaft driving the screening plate to rotate when the soil is screened.
