Problems solved by technology

However, this puts forward higher requirements on the soil leaching simulation device. However, the existing leaching device leaches the soil in the form of a water column during leaching, which is prone to soil disturbance, and it is difficult to control the amount of water and inflow. Water strength, so generally can not meet the test needs

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] As shown in Figures 1 to 4, the present invention includes a water inlet bracket 1, a water inlet 2, a main bracket 6, and a leaching column 10. A crossbeam 8 is arranged between the two sides of the main bracket 6, and the leaching column 10 passes through the leaching column. The column-melting clamping device 7 is detachably installed on the crossbeam 8 on one side of the main bracket 6 , the other side of the main bracket 6 is fixedly connected with a slideway 13 , and the water inlet bracket 1 is placed in the slideway 13 reciprocally and slidably. The middle of the clamping device 7 for the leaching column is arc-shaped, and the two sides are block-shaped. The water inlet 2 is installed on the water inlet bracket 1 through the water inlet bracket clamping device 4 to move up and down, and is located above the leaching column 10. One end of the wa...

Abstract

The present invention relates to soil research equipment, and is especially one kind of soil eluviation simulator for laboratory use. The soil eluviation simulator includes a water feeding support, a water feeder with valve and mounted on the water feeding support, a main frame and an eluviating column fixed on the main frame and below the water feeder. The eluviating column with sampling holes is mounted detachably through a fastener on one side of the main frame, and the water feeding support is set in the slide water on the other side of the main frame. The present invention has simple structure, convenient operation, high eluviating effect, less disturbance on the soil, adjustable water feeding amount and strength, less eluviation simulating error and capacity of recovering the leached liquid.

Description

technical field [0001] The invention relates to a soil research device, in particular to a soil leaching simulation device used in a laboratory. Background technique [0002] When people study the vertical migration of various elements in soil, it is necessary to arrange experiments in the field according to different research purposes. Firstly, pipes need to be buried underground to collect leaching water, and the soil of each test area must be surrounded to prevent flow measurement. Although such field experiments can reflect the actual situation in the field, the research process is too lengthy, the workload is heavy, and a lot of investment is required. human and material resources. Therefore, people hope to overcome the defects of field experiments by establishing a leaching device indoors that can simulate the soil layer in the field. However, this puts forward higher requirements on the soil leaching simulation device. However, the existing leaching device leaches t...
