Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment for engineering supervision, and specifically relates to an engineering sampling device. Background Art

[0002] A construction site refers to a construction site where housing construction, civil engineering, equipment installation, pipeline laying and other construction activities are carried out for industrial and civil projects, construction sites that are approved for occupation and places where humans conduct safe production, civilized work and construction, including all areas on land, sea and air where construction work can be carried out. At the construction site, sampling devices are required to extract and test bagged or canned cement, sand and other materials to check whether bagged or canned cement, sand and other construction materials are qualified.

[0003] Commonly used sampling equipment includes a bagged or canned cement sampling device for engineering supervision disclosed in announcement number CN212379055U. The sampling device is clamped on the cement bag by the elastic strip and convex edge on the fixed tube, and then the sampling needle is driven to rotate by the crank. With the cooperation of the threaded section and the screw hole and the sliding of the slider inside the sampling tube, the conical head is easily inserted into the cement bag through the opening of the cone, so that the cement bag is punctured. In this way, the setting of the conical head reduces the damage to the cement bag while sampling. After the sampling is completed, the sampling tube and the cone at the front end are separated from the fixed tube. After separation, the opening of the cone can be sealed again by the sampling needle, reducing the leakage of the sampled material. However, in the actual sampling process:

[0004] 1. Construction materials such as cement or sand and gravel are prone to increase in density during long-term pushing and squeezing. Therefore, when using the above sampling device for sampling, it is easy for the density of the material to increase and then cause the collapse of the material to be unable to be effectively completed during sampling, resulting in the inability to effectively complete the sampling of sufficient materials, which seriously affects the sampling efficiency;

[0005] 2. At the same time, when sampling and testing samples, in order to ensure the detection effect, it is necessary to perform fixed-depth sampling and testing. After sampling, the sampling port needs to be closed to ensure the accuracy of sampling. However, the above device is not designed with a structure that can complete the sealing of the sampling port, so it is impossible to effectively ensure the accuracy of the sampled samples;

[0006] Therefore, the utility model proposes an engineering sampling device to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0007] In view of this, the main purpose of the utility model is to provide an engineering sampling device.

[0008] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0009] An engineering sampling device comprises a sampling rod, one end of which is provided with a handle, and further comprises

[0010] The sampling mechanism is arranged in the sampling rod, comprising

[0011] The sampling tube is arranged in the installation groove of the sampling rod, and a sampling port is opened on the side wall of the sampling tube;

[0015] In a preferred embodiment, the sampling assembly comprises a sampling port baffle, which is rotatably disposed between the sampling rod and the sampling barrel and matches the sampling port.

[0016] In a preferred embodiment, a plurality of guide slide blocks are further provided on the outer side surface of the sampling port baffle, and the guide slide blocks match the slide grooves provided on the inner side wall of the sampling rod.

[0017] In a preferred embodiment, the injection control assembly includes a rotating ring rotatably disposed on the operating end of the sampling rod, and the rotating ring is connected to the sampling port baffle through a connecting rod.

[0018] In a preferred embodiment, a clamping groove is provided at one end of the rotating ring, a clamping block is movably clamped in the clamping groove, and the clamping block is slidably connected to the sampling rod.

[0019] In a preferred embodiment, a limiting rod is provided at one end of the clamping block, and a compression spring is provided at one end of the limiting rod.

[0020] In a preferred embodiment, a limit block is further provided at the bottom of the movable groove between the sampling rod and the sampling tube, and the limit block matches the sampling port baffle.

[0021] In a preferred embodiment, the auxiliary sampling assembly includes a motor, which is arranged in the handle, and a rotating rod is arranged at one end of the motor, one end of the rotating rod passes through the handle and the sampling rod in sequence, and an eccentric wheel is also arranged at one end of the rotating rod extending into the interior of the sampling rod, and the eccentric wheel matches the inner cavity of the sampling rod.

[0022] In a preferred embodiment, the other end of the sampling rod is also threadedly connected with a tapered rod.

[0023] In a preferred embodiment, a scale is provided on the outer side of the sampling rod.

[0024] Compared with the prior art, the utility model provides an engineering sampling device, which has the following beneficial effects:

[0025] 1. By setting an auxiliary sampling component, when quickly sampling bagged or canned cement, the notch on the surface of the sampling rod cooperates with the mounting groove on the sampling tube. When inserted into the bagged or canned cement, the sampling port is upward to allow the cement to fall into the sampling tube. The motor drives the rotating rod to rotate the eccentric wheel. The sampling rod vibrates due to the inertia generated by the rotation of the eccentric wheel, which can make the cement fall downward into the sampling tube, so as to quickly sample the bagged or canned cement. The opening can break up the lumps in the bagged or canned cement, thereby improving the use effect of the device. The limit block at the bottom of the sampling tube can quickly install the sampling tube in the sampling rod and limit it. The sampling port baffle can protect the cement in the sampling tube through the guide slider and the slide groove to prevent the cement from spilling everywhere, and can complete fixed-depth sampling, so as to quickly sample the bagged or canned cement and improve the sampling effect of the device.

[0026] 2. By setting up the sampling control component and the sampling component, when sampling bagged or canned cement, rotating the rotating ring through the connecting plate can drive the sampling port baffle to rotate to open or close the sampling rod, so as to quickly sample the bagged or canned cement and protect the cement after sampling. The rotating ring can be limited and fixed by cooperating with the card block through two card slots, and the card block can be clamped into the rotating ring through the limit rod and the compression spring. The tapered rod can enable the sampling rod to be quickly inserted into the bagged or canned cement for sampling, and the tapered rod can be removed by rotating it. The sampling barrel in the sampling rod can be installed and disassembled, which can improve the sampling efficiency of the device and prevent the sample from spilling; the purpose of quickly sampling bagged or canned cement is achieved.
