Automatic sampling device for building site construction soil

Abstract

The invention discloses an automatic sampling device for building site construction soil. The automatic sampling device for building site construction soil comprises a base; the outer end of the baseis movably connected with a scaffold through a rotating shaft; the middle of the upper end of the base is fixedly connected with a motor; the rotating shaft end at the lower end of the motor is fixedly connected with a threaded barrel through a rotary shaft; an inner cavity of the threaded barrel is in threaded connection with a nut; the lower end of the nut fixedly communicates with a sampling barrel; the lower end of the sampling barrel is fixedly connected with a blade drill; a push plate is movably inserted at the upper end of an inner cavity of the sampling barrel; a push rod is fixedly connected to the upper end of the push plate; the upper end of the push rod movably penetrates through the base and is fixedly connected with a fixing ring; and a buckle is fixedly connected to the upper end of the base through a fastening bolt. Through arrangement of the motor, the threaded barrel, the nut, the sampling barrel, the push rod, the fixing ring and the buckle, the effect of convenient, quick, time-saving and labor-saving sampling is achieved by starting the motor and using the buckle.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to an automatic soil sampling device for construction sites. Background technique [0002] Soil sampling refers to the method of collecting soil samples, including sampling layout and sampling techniques. Section soil samples should be taken after the observation and recording of the section is completed. Before sampling, the section should be repaired and cleaned to remove the top layer of floating soil, and then sampled from the typical central part layer by layer from top to bottom. At present, before the construction of the project, it is necessary to conduct a general survey, soil monitoring and soil testing formula on the soil of the construction site. The data are used to judge the depth of the foundation and the weight of the total building. This is a particularly important task before construction. Sampling devices are indispensable.

At present, before the construction of the project, it is necessary to conduct a general survey, soil monitoring and soil testing formula on the soil of the construction site. The data are used to judge the depth of the foundation and the weight of the total building. This is a particularly important task before construction. Sampling devices are indispensable. There are many types of soil samplers. Although the existing manual soil samplers are simple in structure and low in cost, they are time-consuming and laborious. After sampling, the cylinder is pressed into the soil layer and is not easy to pull out. The obtained soil samples are not easy to take out from the sampling cylinder, which makes soil sampling difficult and cannot meet the requirements of soil sampling. The mechanically operated soil drilling drill is driven by a motor to make the drill body enter the soil at a certain depth, and then lift the soil column up. ,Place it horizontally for observation, cut and sample as needed. The mechanical drill has high efficiency and can save manpower, but it is not as flexible and light as manual drills.
