Soil sampling device for municipal construction

Abstract

The invention discloses a soil sampling device for municipal construction. The soil sampling device comprises a bottom plate, wherein a side face of the bottom plate is provided with a slide way; the internal thread turning direction of a first casing block is reverse to that of a second casing block; lower ends of the first casing block and the second casing block are hinged with connecting rods; lower ends of the connecting rods are hinged to a connection block; a right side of a first vertical column is provided with a reducing motor; a driving gear is fixedly arranged on a motor shaft of the reducing motor; a driven gear is fixedly arranged at a right end of a lead screw; the driven gear is in meshed connection with the driving gear; a bracket is vertically and fixedly arranged at a right end of the bottom plate; a threaded sleeve is horizontally arranged on the bracket; a threaded rod is inserted into the threaded sleeve; the threaded rod is in threaded connection with the threaded sleeve in a matching way. By adopting the soil sampling device, the sampling position of a sampling pipe can be changed, so that the sampling range is enlarged; meanwhile, hard stones can be avoided in order to protect the sampling pipe from being damaged; a stud can be rotated to adjust the sampling depth of the sampling pipe, so that the adjustment flexibility is enhanced, and the practicability of the soil sampling device is improved.

Description

technical field [0001] The invention relates to the technical field of municipal construction machinery, in particular to a soil sampling device for municipal construction. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity, telecommunications, Heat, gas, etc., as well as the construction of squares, gardens, etc., all belong to the category of ...

AI Technical Summary

Problems solved by technology

[0003] In the process of municipal construction, it is often necessary to sample the soil in the construction area, and judge and analyze the geological characteristics of the construction area through the analysis of the characteristics of the soil, so as to better adopt a relatively optimized construction plan; the existing soil sampling Most of the devices adopt stamping sampling method, and the impact load is relatively large. When encountering relatively hard soil or stones, a large impact load will be generated, which will seriously affect the stability of the sampling device, thereby affecting the sampling quality. At the same time, the existing soil Sampling devices are poorly adjustable and cannot meet current soil sampling requirements
