Description

Technical Field

[0001] This utility model relates to the field of sampling technology for building materials, and in particular to a sampling device for testing building materials. Background Technology

[0002] Building materials are the various materials used in construction projects. They form the foundation of a building's structure and directly affect its safety, usability, and durability. Building materials include basic materials used in various parts of a building, such as walls, floors, roofs, doors, and windows, as well as finishing materials.

[0003] Building materials are the cornerstone of construction projects. They not only directly affect the structural stability, lifespan, safety, energy efficiency, and appearance of buildings, but also have a direct impact on the functionality, durability, and maintenance costs of buildings. When using building materials, multiple sampling tests are usually required. However, during the sampling process, residues from previous samples may affect the results of subsequent tests. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sampling device for testing building materials.

[0005] This utility model is achieved by the following technical solution: a sampling device for testing building materials, comprising a sampling mechanism, a transmission mechanism and a main body mechanism, wherein the sampling mechanism is located on the outer wall of the transmission mechanism and the transmission mechanism is located on the outer wall of the main body mechanism;

[0006] The sampling mechanism includes a sampling barrel, a control cylinder is fixedly connected to the upper surface of the sampling barrel, a pneumatic connecting rod is fixedly connected to the outer wall of the control cylinder, and a scraper is fixedly connected to the lower surface of the pneumatic connecting rod.

[0007] Through the above technical solution, the sampling bucket is fixedly connected to a control cylinder, and the control cylinder is fixedly connected to a pneumatic connecting rod. The control cylinder controls the pneumatic connecting rod to retract. A scraper is fixedly connected to the pneumatic connecting rod. After sampling, the scraper can be moved by the control cylinder to clean the inner wall of the sampling bucket, preventing residue inside the sampling bucket from affecting the effect of subsequent sampling and testing, and increasing the accuracy of subsequent testing.

[0008] As a further improvement to the above scheme, a drive shaft is fixedly connected to the outer wall of the sampling bucket, and a first motor is fixedly connected to the outer wall of the drive shaft.

[0009] Through the above technical solution, the sampling bucket is fixedly connected to the drive shaft, and the drive shaft is fixedly connected to the first motor. The first motor drives the drive shaft to rotate, thereby driving the connected sampling bucket to rotate. The high-speed rotation of the sampling bucket can cut the sampled material, so that the sampling bucket can sample the building material.

[0010] As a further improvement to the above solution, a fixing nut is fixedly connected to the outer wall of the first motor, and a fixing bracket is threadedly connected to the outer wall of the fixing nut.

[0011] Through the above technical solution, the first motor is fixedly connected to the fixing nut, and the fixing nut is threadedly connected to the fixing bracket. The fixing nut can fix the first motor to the outer wall of the fixing bracket, thereby increasing the stability of the first motor during operation.

[0012] As a further improvement to the above solution, the transmission mechanism includes a second motor, a lead screw is fixedly connected to the outer wall of the second motor, and a first slider is rotatably connected to the outer wall of the lead screw.

[0013] With the above technical solution, the second motor is fixedly connected to the lead screw, and the lead screw is rotatably connected to the first slider. The second motor controls the lead screw to rotate, thereby controlling the first slider to move linearly. By setting the first slider to be fixedly connected to the fixed bracket, when the second motor controls the first slider to move, the first slider simultaneously drives the fixed bracket to move as well, thereby adjusting the position of the sampling bucket. Thus, the second motor can directly control the sampling bucket to move up and down.

[0014] As a further improvement to the above solution, a second slider is fixedly connected to the outer wall of the fixed bracket, and a sliding rod is slidably connected to the inner wall of the second slider, with a buffer spring provided at the bottom end of the sliding rod.

[0015] Through the above technical solution, the fixed bracket is fixedly connected to the second slider, and the second slider is slidably connected to the slide rod. The slide rod can provide guidance for the second slider and increase the smoothness of the device's up and down movement. By setting a buffer spring at the bottom of the slide rod, the impact force when the second slider touches the bottom can be reduced.

[0016] As a further improvement to the above solution, the main structure includes a main support, a handle is fixedly connected to the outer wall of the main support, a foot support is fixedly connected to the outer wall of the main support, and a pin is fixedly connected to the lower surface of the foot support.

[0017] Through the above technical solution, the main support is fixedly connected to the handle and the main support is fixedly connected to the foot support. By setting the pin on the lower surface of the foot support, when the equipment moves to the sampling position, the pin can be inserted into the ground, thereby increasing the stability of the equipment during sampling.

[0018] As a further improvement to the above solution, a rotating shaft is fixedly connected to the outer wall of the main support, and a rubber wheel is fixedly connected to the outer wall of the rotating shaft.

[0019] Through the above technical solution, the main support is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the rubber wheel. By setting the rubber wheel at the bottom of the equipment, the overall flexibility of the equipment can be increased.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention features a sampling barrel fixedly connected to a control cylinder, which in turn is fixedly connected to a pneumatic connecting rod. The control cylinder controls the retraction of the pneumatic connecting rod, which is then fixedly connected to a scraper. After sampling, the control cylinder moves the scraper to effectively clean residual material from the inner wall of the sampling barrel, ensuring the accuracy of subsequent sampling and testing. A drive shaft is also fixedly connected to the sampling barrel, and a first motor is fixedly connected to the drive shaft. The first motor drives the drive shaft to rotate, which in turn rotates the connected sampling barrel. This high-speed rotation of the sampling barrel allows for cutting of the sampled material, which is beneficial for sampling harder building materials, increasing sampling efficiency and quality. A fixing nut is fixedly connected to the first motor, and the fixing nut is threadedly connected to a fixing bracket. The fixing nut secures the first motor to the outer wall of the fixing bracket, increasing the stability of the first motor during operation.

[0022] This invention features a second motor fixedly connected to a lead screw, which rotatably connects to a first slider. The second motor controls the rotation of the lead screw, thereby controlling the linear movement of the first slider. A fixed bracket is also fixedly connected to the first slider. When the second motor moves the first slider, the fixed bracket moves simultaneously. This allows for flexible adjustment of the sampling bucket position according to different sampling needs, meeting the sampling requirements of building materials at different heights and depths. A buffer spring at the bottom of the slider reduces the impact force when the second slider touches the bottom, protecting the mechanical structure of the sampling device and extending its service life.

[0040] The implementation principle of a sampling device for testing building materials in this embodiment is as follows: A sampling barrel 101 is fixedly connected to a control cylinder 102, which is fixedly connected to a pneumatic connecting rod 103. The control cylinder 102 controls the pneumatic connecting rod 103 to retract. A scraper 104 is fixedly connected to the pneumatic connecting rod 103. After sampling, the scraper 104 can be moved by the control cylinder 102, thereby effectively cleaning the residual material on the inner wall of the sampling barrel 101 and ensuring the accuracy of subsequent sampling and testing. A drive shaft 105 is fixedly connected to the sampling barrel 101, which is fixedly connected to a first motor 106. The first motor 106 drives the drive shaft 105 to rotate, thereby driving the connected sampling barrel 101 to rotate.

When the second motor 201 controls the movement of the first slider 203, the first slider 203 simultaneously drives the fixed bracket 107 to move as well. This allows for flexible adjustment of the sampling bucket position according to different sampling needs, meeting sampling requirements at different heights and depths. A buffer spring 206 is installed at the bottom of the slide bar 204 to reduce the impact force when the second slider 205 touches the bottom, protecting the mechanical structure of the equipment.
