[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figures 1 to 4 , the utility model provides a technical solution:
[0028] A sampling device for concrete detection in construction engineering, comprising a body 1, wherein a motor 2 is fixedly connected inside the body 1, a powder collecting assembly 3 is arranged at the front end of the body 1, a drill tube 4 is movably connected to the front end of the powder collecting assembly 3, a fixing block 5 is fixedly connected to the upper end of the body 1, the powder collecting assembly 3 comprises a cylinder 31 fixedly connected to the front end of the body 1, a plurality of circular holes 312 are opened at the front end of the cylinder 31, a driving gear 32 is fixedly connected to the front end of the output shaft of the motor 2, a rotating wheel 33 is movably connected inside the cylinder 31, an internal gear 331 is fixedly connected inside the rotating wheel 33, a first driven gear 332 is movably connected between the driving gear 32 and the internal gear 331, and the first driven gear 332 is movably connected to the inside of the cylinder 31, and a plurality of fan blades 34 are fixedly connected to the outside of the rotating wheel 33;
[0029] A discharge port 311 is provided at the inner lower end of the cylinder 31, a discharge pipe 35 is fixedly connected to the outer lower end of the cylinder 31, a collection box 36 is fixedly connected to the rear end of the discharge pipe 35, the drill barrel 4 is movably connected to the front end of the machine body 1, a plurality of feed ports 41 are provided at the inner rear end of the drill barrel 4, the driving gear 32, the first driven gear 332 and the internal gear 331 are meshed with each other, and the interior of the drill barrel 4 is connected to the interior of the cylinder 31 through the feed port 41.
[0030] By adopting the above technical solution, when it is necessary to sample and test concrete, first select a structural position with low stress and representativeness, pay attention to avoiding the position of steel bars, align the drill tube 4 at the front end of the device with the support block 63 at the front end of the slide rod 6 to the wall to be tested, start the motor 2, and the output shaft of the motor 2 rotates, and the output shaft of the motor 2 rotates with the driving gear 32 at the front end of the motor 2, and the driving gear 32 rotates with the drill tube 4 that passes through the cylinder 31, and the front end of the drill tube 4 slowly contacts the wall, and then gradually increase the force to move toward the wall to perform detection and sampling. During the working process, the drill tube 4 operates on the wall to generate dust, and at this time, the driving gear 32 inside the cylinder 31 rotates with the first driven gear 332, and the first driven gear 332 rotates through the internal gear 331 with the rotating wheel 33 The wheel 33 rotates, and the fan blades 34 outside the wheel 33 rotate. The fan blades 34 rotate to exhaust air outward, making the air inside the cylinder 31 thinner, so that a negative pressure area is formed inside the cylinder 31, and then the dust inside and outside the drill tube 4 enters the cylinder 31 through the feed port 41 and the circular hole 312 under the negative pressure inside the cylinder 31. When the powder entering the cylinder 31 passes through the discharge port 311, the powder falls into the discharge pipe 35 due to gravity, and the powder inside the discharge pipe 35 enters the collection box 36 through the discharge pipe 35. After the concrete sampling is completed, the dust inside the collection box 36 is cleared to achieve the purpose of cleaning the dust generated during work, thereby avoiding the phenomenon that the dust generated during sampling limits the field of vision of the construction personnel, thereby improving the sampling efficiency of concrete detection.
[0031] Specifically, Figure 4 As shown, the interior of the fixed block 5 is movably connected with a slide bar 6, the lower end of the slide bar 6 is fixedly connected with a rack 61, the outer rear end of the slide bar 6 is movably connected with a spring 62, and the rear end of the spring 62 is fixedly connected to the rear end of the fixed block 5, the front end of the rack 61 is fixedly connected with a support block 63, the front end of the fixed block 5 is movably connected with a second driven gear 7, the upper end of the body 1 is movably connected with a rocker bar 71, the upper end of the rocker bar 71 is movably connected with a touch rod 72, a torsion spring 721 is movably connected between the touch rod 72 and the rocker bar 71, the lower end of the rocker bar 71 is fixedly connected with a knocking block 73, the elastic force of the spring 62 is greater than the gravity exerted on the slide bar 6, and the rack 61 is meshed with the second driven gear 7.
[0032] By adopting the above technical solution, after the concrete is collected, the equipment is taken out from the wall. At this time, the sampled concrete column is adsorbed inside the drill tube 4, and the device is suspended vertically downward. At this time, the slide bar 6 continuously moves forward during the sampling process of the equipment, so that the slide bar 6 is at the front end position of the fixed block 5. At this time, the slide bar 6 is affected by the elastic force of the spring 62, so that the slide bar 6 moves backward. When the rack 61 at the lower end of the slide bar 6 passes the second driven gear 7 at the front end of the fixed block 5, the second driven gear 7 rotates continuously. The rotation of the second driven gear 7 continuously drives the feeler rod 72 to swing. The swing of the feeler rod 72 drives the swing rod 71 to swing in a cycle, so that the knocking block 73 at the lower end of the swing rod 71 continuously knocks the output shaft at the front end of the motor 2, and then generates vibration through knocking, so that the concrete column inside the drill tube 4 is affected by the vibration and separated from the drill tube 4, thereby achieving the effect of easily removing the concrete sampling column inside the drill tube 4, thereby improving the efficiency of concrete sampling and detection.
[0033] Working principle: Align the drill tube 4 at the front end of the device with the support block 63 at the front end of the slide rod 6 to the wall to be detected, start the motor 2, and the output shaft of the motor 2 rotates to drive the driving gear 32 at the front end of the motor 2, and the driving gear 32 rotates to drive the drill tube 4 that penetrates the cylinder 31, and the front end of the drill tube 4 is slowly brought into contact with the wall for detection and sampling. During the working process, the drill tube 4 operates against the wall to generate dust, and the driving gear 32 inside the cylinder 31 rotates to drive the first driven gear 332 to rotate, and the first driven gear 332 rotates through the internal gear 331 to drive the rotating wheel 33 to rotate, and the rotating wheel 33 rotates to drive the fan blades 34 outside the rotating wheel 33 to rotate The fan blades 34 rotate to exhaust air outward, making the air inside the cylinder 31 thinner, so that a negative pressure area is formed inside the cylinder 31, and then the dust inside and outside the drill tube 4 enters the cylinder 31 through the feed port 41 and the circular hole 312 under the negative pressure inside the cylinder 31, and the powder entering the cylinder 31 falls into the discharge pipe 35 when passing through the discharge port 311 due to gravity, and the powder inside the discharge pipe 35 enters the collection box 36 through the discharge pipe 35, so as to clean the dust generated during work, thereby avoiding the phenomenon that the dust generated during sampling causes the construction personnel's field of vision to be limited, thereby improving the sampling efficiency of concrete detection.
