Embodiment

[0012] Before the power is turned on, wipe the inner wall of the mixer (21) box with a damp cloth. Put the soil sample (8) into the soil loading device (9), and spread the soil sample (8) evenly. Inject distilled water from the water injection port (15). Start the power switch (4), set the rotation speed of the mixer (21) to resist, then control the lifting device to slide down the main shaft (7) through the lifting control button (16), when the scraper (18) falls to the distance within the soil sample (8) When the surface layer of soil sample (8) is about 1cm, press the start switch (5). At this time, the nozzle (19) starts to spray quantitative distilled water for the first time, and the scraper (18) starts to stir the soil sample (8) of the upper layer 1cm into the mixer (21), and stirs at a low speed, and the scraper (18) advances The speed can be controlled by the speed adjustment knob (3). Then, the scraper (18) slowly retreats along the shaft, and when the scraper (1...

Abstract

Belonging to the field of geotechnical test method, the invention in particular relates to a configuration apparatus for soil sample specific water content. The apparatus is composed of a main control panel, a lifting device, a soil loading device, a blender, a scraping blade, a nozzle and a pedestal. The main control panel is provided with a starting switch, a speed adjusting knob and a lifting control button. The lifting device is composed of a main shaft, a rotating shaft and a motor, and the rotating shaft can drive the lifting device to slide up and down along the main shaft. The scraping blade can move a soil sample into the blender, and when the scraping blade works, the lifting device is stationary. The blender case is externally provided with a control panel, which can control the low, middle and high gear rotation speed of the blender and the corresponding rotation time, and the case is internally provided with a temperature sensor. The nozzle can adjust the water flow, when the motor starts, the nozzle starts sprinkling of distilled water, then whenever the scraping blade returns, the nozzle automatically sprinkles distilled water, at the same time, the lifting device slide down along the main shaft by 1cm. The configuration apparatus for soil sample specific water content provided by the invention has the characteristics of simple operation, quick configuration and accurate making, etc.

Description

technical field [0001] The patent of the present invention relates to a configuration device for a specific moisture content of soil samples, which belongs to the field of geotechnical test methods. Background technique [0002] In geotechnical engineering tests, configuring soil samples with specific moisture content is one of the most important links. According to the "Standards for Geotechnical Test Methods" (GB / T 50123-1999), when configuring soil samples with specific moisture content in the laboratory, first weigh a certain quality of remolded soil after drying and grinding, and spread it on the enamel Then, spray distilled water evenly on the soil sample, mix well, put it into a container, cover tightly, and moisten it all day and night, so as to achieve the purpose of configuring soil samples with specific moisture content. However, in the actual operation of this method, due to the different properties of various soils, the same configuration method will produce di...
