Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete sampling, in particular to a leakage-proof ready-mixed concrete sampling device. Background Art
[0002] Concrete generally needs to go through steps such as production, transportation, pouring, vibration, and curing. In order to ensure construction quality and project safety, quality control is required at each link, and the concrete before pouring must be tested by sampling.
[0003] In the prior art, such as a concrete sampling device disclosed in Chinese patent application number CN201720175818.6, an outer cylinder is inserted into a predetermined depth of the concrete slurry, and then the inner rod is pulled vertically to open and close the arc plate and the arc cover plate back and forth, so that the concrete slurry can fall vertically into the feed hole, thereby realizing rapid sampling of the concrete slurry. When the device is in use, a lot of concrete slurry falls into the feed hole, which may cause the arc plate and the arc cover plate to not be well closed, and the concrete slurry may also leak from the gap between the arc plate and the arc cover plate, thereby causing the entire sampling equipment to be loose.
[0004] In the prior art, such as Chinese Patent CN 217688023 U, there is a leak-proof ready-mixed concrete sampling device, which includes an outer sleeve, an inner sampling tube, and a connecting rod. The outer sleeve is arranged on the outside, and the inner sampling tube is placed inside the outer sleeve. The connecting rod is installed on the top of the inner sampling tube. The utility model solves the problem of easy leakage of sampled concrete in the prior art. The inner sampling tube is placed as a whole inside the outer sleeve, and then the outer sleeve is inserted to the depth required for sampling. The handle is rotated by hand to cause the connecting rod to drive the inner sampling tube to rotate inside the outer sleeve, so that concrete slurry can fall vertically into each tube body of the inner sampling tube, realizing rapid sampling of concrete slurry. The handle is then rotated by hand to cause the connecting rod to drive the inner sampling tube to rotate inside the outer sleeve, thereby sealing the inner sampling tube and preventing the sampled concrete slurry from leaking to the outside. However, this patent still has the following problems.
[0005] In the above patent, although the patent is provided with an outer sleeve and an inner sampling tube, the inner sampling tube can be closed by rotating the handle by hand to make the connecting rod drive the inner sampling tube to rotate inside the outer sleeve, but the outer sleeve and the inner sampling tube can only be opened or closed as a whole when closing and opening. Therefore, if only the innermost layer of concrete needs to be sampled, the concrete will enter the lower sleeve, upper sleeve, and additional tube together when opening, which may increase the burden of subsequent cleaning and thus affect sampling. Utility Model Content
[0006] The purpose of the utility model is to solve the problem in the prior art that if only the innermost layer of concrete needs to be sampled, the concrete will enter the lower casing, the upper casing and the additional pipe together when it is opened, which may increase the burden of subsequent cleaning and thus affect the sampling. A leak-proof ready-mixed concrete sampling device is proposed.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a leakage-proof ready-mixed concrete sampling device, comprising a main body, wherein the inner wall of the main body is penetrated by three evenly distributed through-holes, a fixing rod is fixedly installed on the top of the main body, and three groups of evenly distributed fixing rings are fixedly installed on the outer wall of the fixing rod, a rotating plate is provided between any group of the three groups of fixing rings, the fixing rod passes through the four rotating plates and is rotatably connected to the rotating plate, the bottoms of the three rotating plates are fixedly installed with connecting rods, and the bottoms of the three connecting rods are respectively fixedly installed with a first baffle, a second baffle and a third baffle, an operating plate is fixedly installed on the top of the main body, three groups of evenly distributed springs are fixedly installed on the side of the operating plate close to the rotating plate, and the ends of the three groups of springs away from the operating plate are fixedly installed with a clamping block, and the end of the clamping block close to the operating plate is fixedly installed with a connecting plate, the side of the connecting plate away from the clamping block passes through the operating plate and is fixedly installed with a pull plate, and one end of the three rotating plates is provided with a clamping groove.

Then the body is inserted into the concrete, and the corresponding pull plate is pulled as required, and the rotating plate is rotated to make the first baffle, the second baffle or the third baffle leave the through-hole and the concrete enter. When the sampling is completed, the first baffle, the second baffle or the third baffle is reset, and the body is pulled out. In this way, the sampling is completed, which reduces the difficulty of cleaning for the staff.

[0025] The effect achieved by the entire embodiment 1 is that when sampling, the staff pulls the pull plate 20, the pull plate 20 drives the connecting plate 19 and the block 18 to move, the spring 17 is compressed, and then the rotating plate 14 is rotated, and the rotating plate 14 drives the connecting rod 6 and the first baffle 3, the second baffle 4 and the third baffle 5 to move until the through-hole 13 is blocked. At this time, the pull plate 20 is released, and the block 18 enters the card slot 16 under the elastic force of the spring 17 to prevent it from shaking due to external force. Then the main body 1 is inserted into the concrete, and the corresponding pull plate 20 is pulled as required, and the rotating plate 14 is rotated so that the first baffle 3, the second baffle 4 or the third baffle 5 leave the through-hole 13, and the concrete enters.

In this way, the sampling is completed, which reduces the difficulty of cleaning for the staff.
[0026] Example 2, as Figures 1-4As shown, further, a support plate 9 is fixedly installed on the top of the main body 1, and a storage plate 21 is fixedly installed on one end of the support plate 9.

The rotating plate 14 drives the connecting rod 6 and the first baffle 3, the second baffle 4 and the third baffle 5 to move until the through-hole 13 is blocked. At this time, the pull plate 20 is released, and the block 18 enters the card slot 16 under the elastic force of the spring 17 to prevent it from shaking due to external force. Then the main body 1 is inserted into the concrete, and the corresponding pull plate 20 is pulled as required, and the rotating plate 14 is rotated so that the first baffle 3, the second baffle 4 or the third baffle 5 leave the through-hole 13, and the concrete enters. When the sampling is completed, the first baffle 3, the second baffle 4 or the third baffle 5 is reset, and the main body 1 is pulled out. In this way, the sampling is completed, which reduces the difficulty of cleaning for the staff. During cleaning, the staff rotates the rotating plate 14, and the rotating plate 14 contacts the support plate 9.
