[0002] During the slump test and standard test block production process in various projects, the test personnel of the test center often encounter problems such as repeated addition of too few samples and repeated dumping of too many samples due to the lack of effective sampling tools in the process of extracting on-site concrete samples. However, the sampling tools used to make concrete samples for the current slump test and standard test blocks do not specify the number of samples, and the number of samples taken each time is uncertain, so repeated addition or dumping is required, which increases the process time. According to the "Standard for Test Methods for Performance of Ordinary Concrete Mixtures" (GB / T50080-2016), the entire slump test duration is required to be no more than 150s. If the test duration is too long, it will have a certain impact on the test data and cause potential errors in the test and detection work. In response to this situation, the present application provides a tool for sampling concrete performance tests. Utility Model Content

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] like Figures 1 to 5 As shown, the tool for sampling concrete performance test provided by the utility model comprises a bucket 1 and a handle 2, the handle 2 is in the shape of a square tube, and a scale line 3 is arranged on the side surface of the handle 2 from its tail end to the front, the bucket 1 comprises a bottom plate 1.1, a side plate 1.2, a back plate 1.3 and a top plate 1.4, the handle 2 is installed on the back plate 1.3, a side plate 1.2 is arranged on both sides of the top of the bottom plate 1.1, the back plate 1.3 is fixedly installed at the tail end of the top of the bottom plate 1.1, the top plate 1.4 is connected to the tail ends of the back plate 1.3 and the top of the side plate 1.2, and the top plate 1.4 is parallel to the bottom plate 1.1, and the part of the top of the side plate 1.2 located in front of the top plate 1.4 is arc-shaped.
[0027] During the operation, the bucket 1 is used to realize the function of quantitative sampling, making the concrete filling process clean and convenient, avoiding the problem of uneven concrete caused by leakage of concrete filling, and improving the accuracy of test and detection work. At the same time, concrete can be quantitatively extracted to avoid operational problems such as large or small amounts when using other tools.
[0028] When conducting a slump test, the handle 2 is directly transformed into a ruler by using the scale line 3 on the handle 2. The tester can directly place the sampling shovel vertically and use the scale on the handle 2 to first measure the slump, which is more convenient and quick, and reduces the workload of on-site test operators.
[0029] A scraper 4 is slidably installed on the top of the bottom plate 1.1, and the two ends and the top of the scraper 4 are in contact with the side plate 1.2 and the top plate 1.4 respectively. A slide rod 5 is connected to the back of the scraper 4, and the slide rod 5 is inserted into the handle 2. A push rod 6 for pushing and pulling the slide rod 5 is provided at the tail end of the slide rod 5.
[0030] When pouring out the concrete in the bucket 1, the push rod 6 is directly pushed, and the push rod 6 drives the sliding rod 5 to move, and the sliding rod 5 pushes the scraper 4 to move forward from the bucket 1. In this process, the scraper 4 can directly discharge all the concrete samples in the bucket 1, thereby improving the discharge effect. At the same time, the sliding rod 5 and the push rod 6 are integrated on the handle 2, making the tool more compact and small in size, and convenient to carry and use.
[0031] The slide bar 5 is in the shape of a square tube that matches the inner size of the handle 2. The push rod 6 is slidably mounted at the tail end of the slide bar 5, and a displacement groove 7 for the displacement of the push rod 6 is provided on the surface of the handle 2. A socket 8 for the push rod 6 to pass through is provided on the handle 2, and when the push rod 6 passes through the socket 8, the back of the scraper 4 is close to the back plate 1.3. By passing the bottom end of the push rod 6 through the socket 8, the push rod 6 fixes the slide bar 5 at the innermost position of the handle 2, so that the scraper 4 remains in a state of being close to the back plate 1.3. When the concrete in the bucket 1 is discharged by displacement of the scraper 4, the push rod 6 is first pulled so that one end of the push rod 6 passes through the socket 8 and enters the handle 2, and the push rod 6 can be used to directly push the slide bar 5.
[0032] There are multiple sockets 8, which are sequentially distributed in the length direction of the handle 2. At this time, when the push rod 6 passes through different sockets 8, the scraper 4 can be positioned at different positions in the bucket 1, and then the amount of sample scooped by the bucket 1 can be controlled, achieving quantitative sampling functions of different levels.
[0033] An outer row groove 9 is provided at the connection between the bottom of the back plate 1.3 and the bottom plate 1.1, and the outer row groove 9 is in a strip shape. By providing the outer row groove 9, when the scraper 4 moves into the bucket 1 and is close to the back plate 1.3, the bottom of the back of the scraper 4 can scrape the concrete remaining on the upper surface of the bottom plate 1.1 out of the outer row groove 9, so that the scraper 4 can move more smoothly in the bucket 1 without jamming and blocking.
[0034] The bottom of the back of the scraper 4 is provided with a convex strip 10, the length and width of the convex strip 10 are adapted to the outer row groove 9, and the groove cavity height of the outer row groove 9 is greater than the thickness of the convex strip 10. When the scraper 4 moves in the bucket 1, the convex strip 10 moves on the upper surface of the bottom plate 1.1, and the convex strip 10 improves the support effect on the scraper 4, making the scraper 4 more stable when moving. When the scraper 4 is close to the back plate 1.3, the cam completely discharges the concrete sample in the outer row groove 9 from the bucket 1, maintaining the dredging performance of the outer row groove 9.
[0035] The handle 2 and the slide bar 5 are both in a state where the tail ends are tilted upward, the front end of the slide bar 5 is slidably mounted on the scraper 4, a slide groove 11 is provided on the inner side surface of the connection between the side plate 1.2 and the bottom plate 1.1, and a slider 12 is provided at the bottom of both ends of the scraper 4 to slide in the slide groove 11. The cooperation between the slider 12 and the slide groove 11 can ensure the stability of the scraper 4 during displacement, so that the scraper 4 can always be displaced close to the upper surface of the bottom plate 1.1, thereby achieving the effect of effectively scraping the concrete sample in the bucket 1.
[0036] Two cylindrical lifting grooves 13 are provided on the back of the scraper 4, and a sliding column 14 is provided on the front end of the slide bar 5 to slide in the lifting groove. The handle 2 is tilted to facilitate shoveling concrete samples. At the same time, when the slide bar 5 moves to push the scraper 4 to move in the bucket 1, the sliding column 14 moves up and down in the cylindrical lifting groove 13. At this time, the slider 12 cooperates with the sliding groove 11 to prevent the scraper 4 from being separated from the bottom plate 1.1 when the slide bar 5 is lifted or lowered.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
