[0002] A building concrete performance testing sampling device is a device used to test the performance of concrete. It is mainly used to take samples from concrete for subsequent performance testing. Building concrete performance testing sampling devices are mainly used in concrete components during or after construction to collect samples through methods such as core drilling and cutting to test the strength, durability and other performance parameters of concrete.

However, existing sampling devices use the friction inside the sampling tube to remove concrete samples from the road surface. Because the sampling device vibrates when adjusting the sampling tube, the concrete samples inside the sampling tube may slip out, causing inconvenience for workers when collecting concrete samples.

A transmission rod 37 is fixedly connected to the driving end of the first motor 32. The transmission rod 37 is rotatably connected to the inside of the sampling cylinder 31. The transmission rod 37 is threadedly connected to the inside of the slider 35. A clamping block 310 is fixedly connected to the bottom end of the clamping strip 39. A power assembly is provided at the top of the sampling cylinder 31.

[0023] Specifically, the power assembly includes a battery 34, which is fixedly connected to the top of the sampling cylinder 31. A connecting wire 33 is fixedly connected between the battery 34 and the first motor 32. The battery 34 and the connecting wire 33 cooperate with the first motor 32 to provide power to the first motor 32.

[0024] Specifically, a dust removal device 4 is provided on the surface of the driver 2. The dust removal device 4 includes a guide rod 41, which is slidably connected to the inside of the driver 2. A dust suction ring 42 is fixedly connected to the bottom end of the guide rod 41, and the dust suction ring 42 is located on the outside of the sampling cylinder 31.

[0025] In this embodiment, the guide rod 41 can cooperate with the driver 2 to guide the guide rod 41 to slide.

[0026] In this embodiment: connecting pipes 43 are fixedly connected to both sides of the dust suction ring 42, and a threaded disc 44 is rotatably connected to the other end of the connecting pipe 43. An exhaust pipe 48 is fixedly connected to the outer surface of the main frame 1. The connecting pipes 43 can cooperate with the dust suction ring 42 to guide the flow of dust.

[0027] Specifically, a second motor 47 is fixedly connected inside the exhaust pipe 48, and a fan blade 46 is fixedly connected to the drive end of the second motor 47. The fan blade 46 is located inside the exhaust pipe 48.

[0028] In this embodiment, the second motor 47 can cooperate with the fan blade 46 to achieve the purpose of dust extraction.

[0029] Specifically, a cloth bag 45 is placed inside the exhaust pipe 48, and a threaded disc 44 is placed on the upper surface of the cloth bag 45. The threaded disc 44 is threadedly connected to the inside of the exhaust pipe 48. A threaded rod is threadedly connected to the inside of the driver 2, and the threaded rod is located on one side of the guide rod 41.

[0030] In this embodiment, the filter bag 45 can be used in conjunction with the exhaust pipe 48 to achieve the purpose of filtering dust.

[0031] Working Principle: By setting up the clamping device 3, when the worker needs to remove the concrete sample, the worker turns on the battery 34. The battery 34 supplies power to the first motor 32 via the connecting cable 33. The worker remotely controls the first motor 32, which drives the conveyor rod 37. The conveyor rod 37 rotates and pushes the slider 35. The slider 35 drives the clamping strips 39, which disengage from the receiving groove 36 and move closer together. The clamping strips 39 drive the clamping block 310, which clamps the root of the concrete sample. The stabilizing block 38 on the surface of the clamping strips 39 contacts the concrete sample. The worker controls the main frame 1 to adjust the height of the driver 2. The driver 2 drives the sampling cylinder 31 to detach from the road surface. The sampling cylinder 31 carries the concrete sample. The worker controls the first motor 32, which starts the conveyor rod 37. The conveyor rod 37 rotates and adjusts the slider 35. The slider 35 drives the clamping strips 39 away from each other. The clamping strips 39 and the stabilizing block 38 lose their restraint on the concrete sample, and the concrete sample slides out of the sampling cylinder 31. This is achieved by setting up the clamping device... The sampling device 31 allows workers to easily retrieve concrete samples, preventing samples from slipping out and reducing the difficulty of sampling. Additionally, the dust removal device 4 allows workers to rotate the threaded rod when sampling, causing it to retract and release its restraint on the guide rod 41. The guide rod 41 then slides and pushes the suction ring 42, which comes into contact with the ground, activating the second motor 47. The second motor 47 drives the fan blades 46, which rotate and draw air from the connecting pipe 43. The connecting pipe 43 then draws air from the suction ring 42, which in turn draws in dust generated during the processing of the sampling cylinder 31. The connecting pipe 43 guides the dust to contact the filter bag 45, which filters the dust. The air is then discharged from the exhaust pipe 48. By using the dust removal device 4, concrete sampling can be effectively performed, preventing workers from generating large amounts of dust during sampling, thus protecting their health and conserving water resources.
