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

Embodiment Construction

[0037] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] As shown in the figure, a drying and screening device before soil improvement includes a cylinder structure 1, an annular step 2 is arranged on the inner wall of the cylinder structure 1, and a circular filter screen 3 is arranged on the annular step 2 to filter The size and diameter of the sieve 3 is the same as that of the annular step 2, and there are some holes evenly distributed on the filter sieve 3;

[0039] The active rotating rod 4 and the driven rotating rod 5 are arranged in the cylinder structure 1. One end of the driving rotating rod 4 and one end of the driven rotating rod 5 are connected and perpendicular to each other to form a "7" shape. The other end of the driving rotating rod 4 Connect the central position of the inner bottom of the cylinder structure 1 to realize rotation. The other end of the driven ro...

Abstract

The invention discloses a drying and screening device used before soil improvement. The device comprises a tube structure, and a circle of annular step surrounds the inner wall of the tube structure. A round filtering screen is arranged on the annular step. A drive rotary rod and a driven rotary rod are arranged in the tube structure. One end of the drive rotary rod is connected with and perpendicular to one end of the driven rotary rod. The other end of the drive rotary rod is connected with the center position of the bottom in the tube structure. An oval joggling roller is arranged at the other end of the driven rotary rod and located between the annular step and the filtering screen. An air blower flue is arranged on the tube structure. Compared with the prior art, the drive rotary rod rotates in the radial direction to drive the driven rotary rod to convolute, so that the joggling roller is driven to roll between the annular step and the filtering screen, vibration and joggling are achieved, soil blocks placed on the filtering screen crack under strong vibration, and then soil is screened.

Description

technical field [0001] The invention relates to a soil filtering device, in particular to a drying and screening device before soil improvement, and belongs to the technical field of soil screening devices. Background technique [0002] Due to the pollution of the environment caused by the over-exploitation of land by humans, many soils can no longer meet the requirements of planting plants, and some polluted soils need to be improved, and now there are many soils that are not easy to crush due to insufficient nutrients. There are still a lot of stones in the soil, which is not conducive to the growth of flowers and plants when we plant farms or for indoor flowers and plants. If there are too many stones, it will be difficult for plants to absorb nutrients, and it is easy to press the plants and cause the plants to die; For the planting of plants, there are also corresponding requirements for the soil. If the soil is lumpy, not soft enough, poor in air permeability, and rich...
