Screening and separating device for fine soil before soil improvement

Abstract

The invention discloses a screening and separating device for fine soil before soil improvement. The screening and separating device comprises a cylinder structure. Annular steps are arranged on the inner wall of the cylinder structure by a circle. A round filtering screen is arranged on the annular steps. A driving rotating rod and a driven rotating rod are arranged in the cylinder structure. One end of the driving rotating rod and one end of the driven rotating rod are connected and are perpendicular to each other. The other end of the driving rotating rod is connected with the center position of the inner bottom of the cylinder structure, and the other end of the driven rotating rod is provided with an elliptical jittering wheel. The jittering wheel is located between the annular steps and the filtering screen. A gravel separation layer is arranged close to the bottom of the cylinder structure. Compared with the prior art, the driving rotating rod rotates in the radial direction to drive the driven rotating rod to rotate in a circling mode, so that the jittering wheel is driven to roll between the annular steps and the filtering screen to achieve vibration and jittering, soil lumps put on the filtering screen are broken into small soil lumps under the intense vibration, and then the screening process of the soil is formed.

Description

Technical field [0001] The invention involves a soil filtering device, especially a fine soil screening separation device before soil improvement, which belongs to the field of soil screening device technology. Background technique [0002] Due to the pollution caused by over -development of the land to the environment, many soils can no longer meet the requirements of planting plants, and some pollution soil quality needs to be improved. Now there are many soils because of insufficient nutrients and there are many rough pieces that are not crushed.There are still many stones in the soil. In our planting dealer or the planting of indoor flowers and plants, it is very unfavorable to the growth of flowers and plants. If there are too many stones, it is difficult for plants to absorb nutrients, and it is easy to press plants, resulting in plant death;For plant planting, there are corresponding requirements for the soil. If the soil is in block, it is not soft enough, the breathabili...

Problems solved by technology

[0005] Although the above methods can effectively pulverize the soil, because other smashing and impacting tools in the device are used to smash the agglomerated soil and gravel together, small stones will also be incorporated into the soil, which reduces the quality of the soil and cannot achieve The purpose of complete separation of soil and impurities
