specific Embodiment approach 1

[0028] Specific implementation mode one: the following combination Figure 1 to Figure 2 Illustrate this embodiment, the device of measuring soil water stability aggregate described in this embodiment, it comprises horizontal support 1, four hangers 2 and four stainless steel barrels 3, and it also comprises four standard sample sets of sieves 4, support Rod 5, chassis 6, motor 7, gearbox 8, timer 9, bushing 10 and flange 11,

[0029] A motor 7 and a gearbox 8 are fixedly arranged on the inner bottom panel of the chassis 6. The rotating shaft of the motor 7 drives the input shaft of the gearbox 8 to rotate through a V-belt, and an eccentric wheel is sleeved on the output shaft of the gearbox 8. The eccentric wheel The axis is in the horizontal direction, the support rod 5 is located directly above the eccentric wheel, and the lower end of the support rod 5 is in sliding contact with the side wall of the eccentric wheel, and the eccentric wheel is used to drive the support rod ...

specific Embodiment approach 2

[0034] Embodiment 2: This embodiment is a further description of Embodiment 1. The standard sample set sieve 4 is composed of three sieves with different particle sizes, and is socketed from bottom to top according to the particle size from small to large.

[0035] The sieves of the three different particle sizes can be selected from three of the following four particle sizes according to needs, namely >0.1mm particle size, 0.1-0.25mm particle size, 0.25-0.053mm particle size and <0.053mm particle size.

specific Embodiment approach 3

[0036] Specific implementation mode three: the following combination figure 1 This embodiment will be described. This embodiment is a further description of Embodiment 1 or 2. The hanger 2 and the horizontal support 1 are connected by claw nuts.

Abstract

The invention relates to a device and a method for measuring soil water-stable aggregates, belonging to the technical field of soil crumb structures. The device and the method solve the problem that a soil crumb analysis device can measure only one sample at each time to make the measurement efficiency low. The device comprises a horizontal bracket, four hanger frames and four stainless steel barrels, further comprises four standard sample sleeve sieves, a support rod, a case, a motor, a gear box, a timer, a sleeve and a flange plate; the method comprises the following steps: timing with the timer, controlling the motor to star, wetly sieving the soil samples, and calculating mass fraction of the obtained soil water-stable aggregates. According to the invention, the device and the method are suitable for measuring soil water-stable aggregates.

Description

technical field [0001] The invention relates to a device and method for measuring soil water-stable aggregates, belonging to the technical field of soil aggregate structures. Background technique [0002] Soil aggregate structure plays an important role in soil fertility. A good aggregate structure should generally have three properties: it has a certain size, too large or too small is not conducive to the formation of an appropriate pore ratio; it has multi-level pores, the large pores can be ventilated and water-permeable, and the small pores can retain water and fertilizer; Certain stability, namely water stability, mechanical stability and biological stability. A good aggregate structure is the foundation of soil fertility. The relationship between aggregate structure and soil fertility is mainly manifested in the following aspects: adjusting the contradiction between soil moisture and air; coordinating the contradiction between the consumption and accumulation of soil ...
