Description

Technical Field

[0001] The utility model relates to a soil aggregate detection lifting structure, belonging to the technical field of soil detection. Background Art

[0002] Soil aggregate structure is an important characteristic of soil. It can reflect the structural characteristics of soil and affect the flow of water, gas and nutrients in the soil, as well as the mechanical properties of soil. Therefore, determining soil aggregate structure is an important part of soil analysis.

[0003] The soil aggregate structure analyzer is used to reveal the characteristics of soil components. It can separate soil particles of standard size without affecting the soil structure. By analyzing the soil particle structure, the characteristics of soil components can be analyzed quickly and effectively, helping agricultural producers to fully understand the properties of the soil, formulate detailed fertilization plans, and improve crop yields and quality.

[0004] Patent application number CN201921083005.X discloses a soil aggregate analyzer, including an oscillation shaft, an oscillation bracket, a main chassis, a set of sieves, a controller and a motor. The motor is used to drive the oscillation shaft to reciprocate up and down, thereby driving the oscillation bracket to make the sieve containing the soil sample reciprocate up and down in the water in the barrel.

[0005] The analyzer disclosed in the above patent still has the following deficiencies during use:

[0006] The oscillating shaft slides vertically in the sleeve, and the inner diameter of the sleeve is the same as the diameter of the oscillating shaft. The oscillating shaft will rotate and shake during movement, which increases the mechanical wear between the oscillating shaft and the sleeve. Without lubrication, it is difficult to ensure the long-term stable operation of the structure. The position determination process of the screen body is relatively troublesome, and the screw needs to be passed vertically through the positioning hole, groove, etc., and then locked by turning the knob.

[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
