Intelligent soil aggregate analyzer

1Intelligent soil aggregate analyzerofProduct Introduction

1. The soil aggregate structure plays an important role in soil fertility. A good granular structure should generally possess three properties: having a certain size, and being too large or too small is not conducive to forming an appropriate proportion of pores; Having multi-level pores, large pores are breathable and permeable, while small pores retain water and nutrients; Has certain stability, including water stability, mechanical stability, and biological stability. Good aggregate structure is the foundation of soil fertility, and the relationship between aggregate structure and soil fertility is mainly manifested in the following aspects: regulating the contradiction between soil moisture and air; Coordinate the contradiction between the consumption and accumulation of soil nutrients; Stabilize soil temperature and regulate soil thermal conditions; Improving soil fertility is beneficial for the extension of crop roots. The soil particle analyzer is suitable for analyzing aggregates in soil, environmental, geological and other laboratory experiments.

2. Method principle

After dry screening the air dried samples, determine the particle distribution under a certain mechanical stability. Then, mix the particle distribution obtained by the dry screening method in the corresponding proportion and wet it in water to determine the quantity and distribution of water stable macroaggregates.

2、 Terminology and definitions

1. Soil aggregates

The total amount of aggregates in soil that vary in size, shape, porosity, mechanical stability, and water stability. It is composed of soil primary particles that are interconnected through the aggregation, cementation, and bonding of colloids.

2. Soil macroaggregates

Aggregates with a diameter of 0.25mm~10m in soil are called soil macroaggregates

3. Soil water stable macroaggregates

It is a large aggregate of soil particles bonded together by organic matter such as calcium and magnesium, mycelium, etc., which is not easily disintegrated by shaking, soaking, and washing in water, but still maintains its original structure.

IIIIntelligent soil aggregate analyzerThe characteristics of the instrument

1. The structure mainly consists of a speed regulator, reduction gear, and balance frame, with small volume, light weight, and no noise;

2. Beautiful appearance, equipped with automatic parking device, safety emergency stop device, leakage protection and other safety devices;

3. Good structure, good performance, and convenient and flexible use of clamp screen.

4. Adjustable speed motor: all copper coil, running smoothly; High torque; efficient; Low noise.

5. Adopting MCU digital control technology, it has rich functions and excellent performance.

6. Using digital menu style options, it is convenient and quick to modify settings.

7. The display magnification can be set according to the user's display needs, and the display target value can be automatically converted.

8. The panel knob automatically matches the highest speed, making speed control convenient and safe.

9. Independent timer, controls start and stop, with clear functions and convenient operation.

10. The locked rotor protection function prevents the motor and speed controller from burning out due to locked rotor. (This function can protect against locked rotor overload, but cannot protect against non locked rotor overload)

11. Leakage protector: short circuit protection/overload protection/leakage protection/flame retardant material

12. Emergency stop button: designed with an anti slip button, it locks when pressed and can be reset by rotating. It can handle emergency situations during the experiment and quickly cut off power.
