Sampling device

Abstract

The invention discloses a sampling device. The sampling device comprises a power source module and a working module. The power source module comprises an electric motor and a rotation handle which is connected with the rotation axle of the electric motor. The working module comprises a base, a support rib plate and a roller, wherein two ends of the roller are mounted on the base by the support rib plate, a large gear is arranged in the middle of the roller, a small gear engaged with the large gear is mounted on the output axle of the electric motor, the output axle of the electric motor is mounted in a small rib plate on the base, a filter screen and a wear cylinder which are arranged on the two sides of the large gear respectively are mounted on the roller, a feeding hopper is connected with the bear cylinder, a material receiving disk is flexibly mounted on the base and arranged below the filter screen, and symmetric handles are fixedly arranged on one side of the base. The sampling device is simple in structure, reasonable in design, small in size, and convenient to carry, and the sampling device can be electrified through various kinds of power supply ways, so that normal use of the sampling device can be ensured, the valuable large-size sample can be ground and screened and then the sample can be taken away for inspection, and thus the worker can conveniently inspect the sample.

Description

technical field [0001] The invention relates to the technical field of sample collection, in particular to a sampler. Background technique [0002] At present, due to the current development and construction in various aspects, a large amount of construction is required. Before the construction, the inspection of the foundation soil layer and sand and gravel layer must be carried out, and then protective measures must be taken during construction, especially in desert and mountain areas. Bringing a large number of samples back for inspection not only wastes manpower and material resources, but also brings great inconvenience to the staff. Contents of the invention [0003] The purpose of the present invention is to overcome the traditional working method to bring a large number of samples back for inspection, and provide a sampler to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides...
