Portable soil fetcher for construction

Abstract

The invention provides a portable soil sampler for building, and belongs to the a building device. The portable soil sampler comprises a transverse rod; two first rotating shafts are symmetrically arranged at the upper end of the transverse rod; every first rotating shaft is fixedly connected with a first movable rod; a sleeve is arranged at the upper ends of the first movable rods; the lower parts of two ends of the transverse rod are fixedly connected with second rotating shafts; the lower ends of the second rotating shafts are fixedly connected with connecting rods; the left lower end of every connecting rod is fixedly connected with an L-shaped block; a clamping block is perpendicularly arranged at the right end of every L-shaped block; the right end of every connecting rod is horizontally fixedly connected with a limiting block; and a spring is connected between the left end of every fixed block and the right end of the corresponding connecting rod. The first movable rods rotate around the first rotating shafts, and are rotated to horizontal positions during use; anti-slid lines increase the friction force to prevent the first movable rods from slipping out of hands during use; and the sleeve limits the first movable rods in a vertical position when the first movable rods are idle, and the sleeve is fixed by a permanent magnet to make the whole device portable.

Description

technical field [0001] The invention relates to construction equipment, in particular to a portable earth borrower for construction. Background technique [0002] At present, it is necessary to carry out census, soil monitoring and soil testing formula on the soil of the construction site before the construction of the project. The data is used to judge the depth of the foundation and the weight of the total building, which is a particularly important work before construction. The soil sampler with the same volume and convenience requirements, although the existing soil sampler has a simple structure and low cost, it is time-consuming and labor-intensive, and is prone to clogging problems during soil sampling, and it is not easy to pull out the cylinder after sampling , the obtained soil sample is not easy to take out from the sampling cylinder, which makes soil sampling difficult, and because the volume cannot be changed, it is also very inconvenient to carry.

Problems solved by technology

[0002] At present, before the construction of the project, it is necessary to carry out general surveys, soil monitoring and soil testing formulas 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. Soil sampler with equal and convenient requirements. Although the existing soil sampler is simple in structure and low in cost, it is time-consuming and laborious, and it is prone to blockage when taking soil. 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 because the volume cannot be changed, it is also very inconvenient to carry. There is an urgent need for a device that can solve the above problems
