Embodiment Construction

[0018] figure 1 As shown, the three-way siphon instrument at least includes a long pipe 4, a short pipe 2 and an elbow 3, and the two ends of the elbow 3 are respectively connected with one end of the long pipe 4 and one end of the short pipe 2 to form an integral pipe, which is a liquid flow The passage through the channel, the overall pipe is in the shape of ∩, the other end of the short pipe 2 is provided with a joint 1 for liquid inlet, the joint 1 is in the shape of a lotus, in order to evenly absorb a certain density of liquid around the liquid plane when absorbing liquid, the joint 1 There are circumferentially symmetrically distributed through-holes on the plane, and usually the soil particle size is not greater than 2mm, so the diameter of the through-holes can be 2mm. In order to control the liquid absorption depth to be placed when absorbing liquid, one end of the short tube 2 connected to the joint 1 and the outer surface of the joint 1 are marked with a scale, and...

Abstract

The invention discloses a tee-joint siphon apparatus, which at least comprises a long pipe, a short pipe and an elbow pipe, wherein two ends of the elbow pipe are respectively connected with one end of the long pipe and one end of the short pipe to form an integral pipe, and the integral pipe is in an inverted U shape; the other end of the short pipe is provided with a joint for liquid inlet, andthe other end of the long pipe is provided with a connector; and the a liquid outlet pipe and an additional pipe are connected to the connector. The tee-joint siphon apparatus has the characteristicsof stable technical performance, simple structure, convenient operation and use, short test period, capability of completing total analysis within 2 hours, high test precision, convenient carrying and maintenance after use and the like, can be applied in fields of geotechnical engineering, geological engineering, scientific research of agricultural soil, teaching and other productivity fields, can meet the requirements of experiments on grain composition of soil, and is possibly helpful for measuring the grain composition in other related fields.

Description

technical field [0001] The invention relates to a three-way siphon instrument, which belongs to the field of soil machinery and can be specifically applied to geotechnical engineering, geological engineering, agricultural soil science research, teaching and other productive fields. Background technique [0002] The soil matrix is ​​composed of particles (soil particles) with different proportions, particle sizes, shapes and compositions, and is generally divided into four grades: gravel, sand, silt and clay. The purpose of particle size analysis is to determine the composition of soil particles of different diameters, thereby determining the texture of the soil. The composition of soil particles is of great significance in soil formation and agricultural utilization of soil. Soil texture directly affects the retention and movement of soil water, fertilizer, air and heat, and is closely related to the growth and development of crops. [0003] The traditional instrument for m...
