Engineering construction raw material sampling device

Abstract

The utility model relates to the technical field of engineering construction, in particular to an engineering construction raw material sampling device which comprises a shell, hinges are fixedly connected to the two sides of the shell, a grip is fixedly connected to one side of each hinge, a clamping assembly is rotationally connected to the surface of the grip, a first clamping groove is formed in one side of the shell, and a second clamping groove is formed in the other side of the shell. And the other side of the shell is fixedly connected with a fixed block. Due to the arrangement of the rotating blade, the feeding hole and the sampling bottle, when the sampling device is used and the drill begins to sample engineering construction raw materials, due to the influence of the protection assembly, generated samples are left in the shell, the rotating blade rotating together with the drill transports the samples into the device, and due to the existence of the baffle plate, the samples can be taken out of the shell. When the sampling bottle is used, samples can enter the sampling bottle through the feeding port, and after the samples are collected, the samples can be prevented from being polluted only by taking down the sampling bottle and covering the sampling bottle with the cover, so that the effect of collecting and protecting the samples is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to an engineering construction raw material sampling device. Background Art

[0002] Witness Sampling: As we all know, the quality of building materials is a fundamental element of construction project quality, and building material inspection is a crucial guarantee for quality control on-site. Therefore, witness sampling and inspection are crucial means to ensure scientific, fair, and accurate inspection. However, witness sampling still presents numerous challenges: some workers fail to accurately and accurately collect samples; some on-site test personnel lack a deep understanding of construction testing and fail to conduct in-depth and detailed research; and some witnesses "testify" without actually seeing the results, engaging in fraudulent practices that render samples unrepresentative and unauthentic. Therefore, the quality of building materials directly impacts the performance of witness sampling.

[0003] The Chinese utility model patent application disclosure CN214373498U discloses a sampling device for engineering construction materials for civil engineering inspection, including a drilling rig, a sampling barrel and a dust cover. The drilling rig includes a housing, a motor, a connecting rod and a power cord. The motor is detachably connected to the housing, the connecting rod is detachably connected to the motor, and the power cord is fixedly connected to the motor. The sampling barrel includes a sampling tube and multiple telescopic rods. The sampling tube is detachably connected to the connecting rod, and the multiple telescopic rods are fixedly connected to the sampling tube. The dust cover includes an inner cover and an outer cover. One end of the inner cover is fixedly connected to the sampling barrel, and the other end is fixedly connected to the motor and covers the outside of the motor. The outer cover is fixedly connected to the housing. The utility model adds inner and outer dust covers to the original sampling machine, which can not only protect the motor but also prevent dust from spreading, solving the problem that a large amount of dust will be generated when the existing sampling device is used, which endangers the health of the operator.

[0004] However, the device lacks portability and cannot be folded when in use, making it inconvenient to carry. Moreover, the device lacks sample collection and storage function. When in use, samples are stored in unprotected sampling tubes, making it easy for samples to be lost or contaminated. Utility Model Content

The surface of the button 401 is rotatably connected to the surface of the handle 2. Through the arrangement of the button 401, the movable block 402, the first clamping block 403 and the first spring 404, when in use, when the handle 2 needs to be stored, by pressing the button 401, the movable block 402 brings the first clamping block 403 to squeeze the spring 404, the limit between the shell 1 and the handle 2 can be released, and the handle 2 can enter the active state, so as to achieve the function of adjusting the handle 2 as needed;

[0025] In this embodiment, preferably, a second card slot 7 is provided on the surface of the housing 1, and a second card block 6 is fixedly connected to the side of the handle 2 away from the housing 1. Due to the arrangement of the second card block 6 and the second card slot 7, when the handle 2 needs to be stored, after releasing the limit between the handle 2 and the housing 1 through the card assembly 4, the second card block 6 is clamped on the inner wall of the second card slot 7 to complete the storage of the handle 2, thereby achieving the purpose of convenient and quick storage of the handle 2;

At this time, most of the samples generated will be inside the shell 1, so as to increase the sample utilization rate.

[0029] When using a sampling device for engineering construction materials of this embodiment, first separate the handle 2 from the shell 1 and press the button 401. At this time, the button 401 will squeeze the movable block 402, causing the first spring 404 to contract, and the first clamping block 403 will move inward with the movable block 402.
