Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a concrete sampling device. Background Art

[0002] Concrete is mainly composed of cement, aggregates (such as sand and stone), water, and possibly added admixtures and additives mixed in a certain proportion. In modern construction projects, sampling the uncured concrete can accurately evaluate the quality of the entire construction project.

[0003] In the related art, a nozzle is directly arranged inside the sampling cylinder to clean the inside of the sampling cylinder. For example, a concrete sampling device disclosed in the patent number CN214471884U has a cleaning pipe fixedly arranged outside the sampling cylinder, and one end of the cleaning pipe is fixedly connected with a nozzle, and the nozzle is located inside the sampling cylinder to facilitate cleaning the inside of the sampling cylinder. However, since the nozzle is fixedly connected with the cleaning pipe and the sampling cylinder has a certain longitudinal depth, there may be a problem that the bottom of the sampling cylinder cannot be cleaned during the cleaning process. It can be seen that the cleaning effect of the concrete sampling device in the related art is poor. Summary of the Utility Model

[0004] In order to improve the cleaning effect of the concrete sampling device, the utility model provides a concrete sampling device.

[0005] The present application provides a concrete sampling device, adopting the following technical solutions:

The first push plate is connected to the top end of the pushing rod, the bottom end of the pushing rod is connected to the second push plate, the spiral nozzle is detachably arranged on the pushing rod, the first push plate is located above the sampling cylinder, the pushing rod is slidably connected to the sampling cylinder, and the second push plate is located inside the sampling cylinder; the pushing rod is a hollow rod.

[0009] Furthermore, it further includes a transverse water supply pipe, which is detachably connected to the pushing rod, and the spiral nozzle is communicated with the transverse water supply pipe through the pushing rod.

[0010] Furthermore, it further includes an electric valve, which is arranged on the transverse water supply pipe.

[0011] Further, two push rods are provided, and the two push rods are arranged in parallel.

[0012] Further, a protective cover is further included. The protective cover is arranged outside the spiral nozzle, and the protective cover is connected to the push rod.

[0013] Further, the second push plate is annular, and the second push plate abuts against the inner wall of the sampling cylinder.

[0014] Further, the plugging assembly includes a plugging plate and a sliding insertion rod. A guiding hole for the sliding insertion rod to pass through is arranged on the outer side of the sampling cylinder. The bottom end of the sliding insertion rod is connected to the plugging plate, and the plugging plate is located at the bottom of the sampling cylinder.

[0015] Further, a rotating handle is arranged at the top end of the sliding insertion rod.

[0016] In summary, the utility model includes the following beneficial technical effects:

[0017] 1. The spiral nozzle is arranged on the push rod, so that the spiral nozzle can move along with the movement of the push rod. The moving spiral nozzle can better and more carefully clean all positions of the sampling cylinder.

[0027] The objective of the present utility model is to provide a concrete sampling device, which realizes the cleaning of concrete through a cleaning component to reduce the influence on the next concrete sampling. Embodiment 1:

[0028] As Figure 1 - Figure 2 shown, the present utility model provides a concrete sampling device, including a pushing component 1, a spiral nozzle 2, a sampling cylinder 3 and a plugging component 4.

[0029] A plugging component 4 is arranged at the bottom of the sampling cylinder 3, and the spiral nozzle 2 is located inside the sampling cylinder 3.

[0030] The pushing component 1 includes a first push plate 101, a pushing rod 102 and a second push plate 103. The edge of the first push plate 101 is fixedly connected to the top end of the pushing rod 102 by an adhesive. There are two pushing rods 102, and the two pushing rods 102 are arranged parallel and vertically. The pushing rod 102 is a hollow rod. The distance between the two pushing rods 102 is the diameter of the first push plate 101. The bottom end of the pushing rod 102 is fixedly connected to the second push plate 103 by an adhesive. The spiral nozzle 2 is detachably arranged on the pushing rod 102. Preferably, a threaded connection is adopted. A plurality of screw holes are arranged in the vertical direction of the pushing rod 102, and the spiral nozzle 2 is provided with matching threads. The number of spiral nozzles 2 can be set according to requirements, and the spiral nozzle 2 is located above the second push plate 103. The first push plate 101 is located above the sampling cylinder 3. The pushing rod 102 is slidably connected to the sampling cylinder 3. The second push plate 103 is located inside the sampling cylinder 3. When the sampling cylinder 3 needs to be cleaned, the spiral nozzle 2 is screwed onto the pushing rod 102 to clean the sampling cylinder 3. Timely disassembly can avoid damaging the spiral nozzle 2 when not in use. Further, when it is not necessary to set the spiral nozzle 2 on the screw hole of the pushing rod 102, in order to avoid the inside of the pushing rod 102 being contaminated by concrete, a threaded plug matching the screw hole can be used to block the screw hole. The present application embodiment does not limit the plug, and the existing technology can be adopted.

[0031] The concrete sampling device further includes a horizontal water supply pipe 5. The horizontal water supply pipe 5 is detachably connected to the pushing rod 102. Preferably, the horizontal water supply pipe 5 can be detachably connected to the pushing rod 102 through a connecting pipe (the horizontal water supply pipe 5 can also be directly threadedly connected to the pushing rod 102), so that the horizontal water supply pipe 5 can be removed when not in use, effectively improving the convenience of using the horizontal water supply pipe 5. The horizontal water supply pipe 5 is vertically arranged with respect to the pushing rod 102, and the horizontal water supply pipe 5 is located below the first push plate 101. The horizontal water supply pipe 5 is connected to an external water supply device through an electric valve 6. By setting the electric valve 6, the automatic adjustment of the water output can be realized, reducing the tediousness of manual adjustment.

[0032] The concrete sampling device further includes a protective cover 7. The protective cover 7 is arranged outside the spiral nozzle 2, and the protective cover 7 is threadedly connected to the pushing rod 102.

[0033] The second push plate 103 is annular. The annular edge of the second push plate 103 slidably abuts against the inner wall of the sampling cylinder 3. It can be understood that by setting the second push plate 103, the residual concrete on the inner wall of the sampling cylinder 3 can be removed. At the same time, the annular shape setting can avoid the accumulation of fallen concrete to better remove the residual concrete.

[0034] Working principle: When the sampling cylinder 3 needs to be cleaned, the horizontal water supply pipe 5 and the spiral nozzle 2 are respectively connected to the push rod 102, and the electric valve 6 is opened. After the electric valve 6 is opened, water flows through the horizontal water supply pipe 5, enters the inside of the push rod 102, and then enters the spiral nozzle 2. The spiral nozzle 2 sprays water to clean the inner wall of the sampling cylinder 3. At the same time, the first push plate 101 is pushed to move the pushing assembly 1 downward. The spiral nozzle 2 moves along with the movement of the push rod 102. While moving, the spiral nozzle 2 sprays clean water to wash the inner wall of the sampling cylinder 3. The second push plate 103 also moves downward along with the movement of the push rod 102. Since the annular edge of the second push plate 103 abuts against the inner wall of the sampling cylinder 3, during the downward movement, the second push plate 103 can scrape the concrete on the inner wall of the sampling cylinder 3. The residual concrete on the inner wall of the sampling cylinder 3 is removed through two dimensions of cleaning with clean water and scraping with the push plate, effectively improving the cleaning effect and reducing the impact on the next concrete sampling.

[0035] Advantages of the present utility model: The spiral nozzle 2 is arranged on the push rod 102, so that the spiral nozzle 2 can move along with the movement of the push rod 102. The moving spiral nozzle 2 can better and more carefully remove the residual concrete at all positions inside the sampling cylinder 3. Compared with ordinary nozzles, the spraying area of the spiral nozzle 2 is larger, effectively improving the spraying efficiency. Combined with the annular second push plate 103, the inner wall of the sampling cylinder 3 is cleaned again to further improve the cleaning effect of the residual concrete in the sampling cylinder 3. Embodiment 2:

[0036] This embodiment further improves Embodiment 1, making it more convenient and smooth to use.

[0037] As Figure 3 shown, it is a schematic diagram of a plugging assembly 4 provided by the present utility model. The plugging assembly 4 includes a plugging plate 401 and two sliding insertion rods 402. Two guiding holes (not shown in the drawings) are symmetrically arranged on the outer side of the sampling cylinder 3. The top ends of the two sliding insertion rods 402 slide through the guiding holes of the sampling cylinder 3 from bottom to top. The bottom ends of the two sliding insertion rods 402 are symmetrically connected to the side surface of the plugging plate 401 through fasteners. The plugging plate 401 includes a first sub-plugging plate 4011 and a second sub-plugging plate 4012. Both the first sub-plugging plate 4011 and the second sub-plugging plate 4012 are circular. The first sub-plugging plate 4011 is located below the sampling cylinder 3, and the second sub-plugging plate 4012 is located below the first sub-plugging plate 4011. By setting two layers, the bottom of the sampling cylinder 3 can be better sealed to prevent concrete from falling during the sampling process. The top end of the sliding insertion rod 402 is fixedly connected with a rotating handle 403 through a fastener. The rotating handle 403 is T-shaped for easy rotation.

[0038] Working principle: When it is necessary to take a sample of concrete, rotate the rotary handle 403 to open the plugging plate 401. At this time, the bottom of the sampling cylinder 3 is in an open state, and the concrete can be sampled. After the concrete sampling is completed, rotate the rotary handle 403 again, and the first sub-plugging plate 4011 and the second plugging plate 4012 plug the bottom of the sampling cylinder 3 to prevent the concrete in the sampling cylinder 3 from being exposed.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
