However, there is currently no dedicated equipment for sampling concrete mixtures, but a shovel is used for sampling. Since the coarse aggregate particles in the concrete mixture will fall off the shovel, it causes a deviation between the quality characteristics of the sampled part and the overall quality characteristics of the concrete mixture, seriously affecting the accuracy of quality detection; moreover, when detecting the slump value, it is also necessary to move the sample to the corresponding detection equipment, and the operation process is complex.

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0026] The following will detail the technical solutions provided by each embodiment of the present utility model in conjunction with the drawings.
[0027] An embodiment of the present utility model provides a sampler for concrete mixture, as Figures 1 to 3 shown. The sampler includes a sample-taking body 1 and a handle rod 2. Among them, the material of the sample-taking body can be carbon steel, and the material of the handle rod can be wood.
[0028] Specifically, a sampling groove with an upward opening is formed on the sample-taking body 1, and the head end of the handle rod 2 is fixedly connected to the outer side wall of the sample-taking body 1; in this way, the sampler can be manually operated to extend into the bottom of the mixer discharge port or the concrete conveying tank for sampling, which can prevent the coarse aggregate particle components in the concrete mixture sample from falling and flowing away, and ensure the uniformity and representativeness of the sampling. Moreover, the shape of the sampling groove is frustum-shaped, and the size ratio of the bottom diameter, the opening diameter and the height of the sampling groove is 1:2:3 in sequence. A handle 3 is provided on the outer side wall of the sample-taking body 1. In this way, after the sampling groove is filled with the concrete mixture sample, the sample-taking body 1 is inverted on the horizontal ground or iron plate, and the sample-taking body 1 is lifted through the handle 3, so that the concrete mixture sample freely collapses under the action of its own gravity. At this time, the slump value and spread value of the mixture can be quickly estimated and detected, and the detected value has a good correlation with the standard detected value and can be applied to the real-time control of concrete production quality.
[0029] In summary, in the sampler of this embodiment, by providing a sampling body with a frustum-shaped sampling groove and a handle rod, it is possible to receive the flowing mixture that freely falls from the outlet of the concrete mixer or dig out the mixture from the concrete delivery tank, realizing manual sampling of the concrete mixture, and the sampling uniformity and representativeness are better; and the dimensional ratio of the bottom diameter, the notch diameter, and the height of the sampling groove is designed to be 1:2:3, and a handle is provided on the outer side wall of the sampling body. The slump value of the concrete mixture can be quickly estimated and detected directly through the sampler, and the operation is more convenient.
[0030] In this embodiment, as Figure 1 and Figure 3 shown, the tail end of the handle rod 2 and the upper end of the sampling body 1 are at the same horizontal height. In this way, when the sampling body 1 is inverted on the horizontal ground or iron plate, the tail end of the handle rod 2 will also contact the horizontal ground or iron plate, realizing the support of the sampler, preventing the sampler from tilting due to unstable center of gravity, and thus ensuring the accuracy of the slump value estimation and detection.
[0031] Moreover, as Figure 1 and Figure 3 shown, the handle rod 2 is fixed to the upper part of the outer side wall of the sampling body 1, which is convenient for lifting the sampling body 1 more steadily through the handle rod 2 to prevent the sample in the sampling body 1 from spilling; the handle 3 is provided at the lower part of the outer side wall of the sampling body 1, which is convenient for lifting the sampling body 1 by the handle 3 when the sampling body 1 is inverted.
[0032] In addition, as Figure 3 shown, the number of the handles 3 is one, and the handle 3 is arranged on the opposite side of the handle rod 2; in this way, the sampling body 1 can be lifted steadily by pulling the handle 3 with one hand and holding the handle rod 2 with the other hand.
[0033] Of course, in other embodiments, the number of the handles is two, and the two handles are symmetrically arranged on both sides of the sampling body. By pulling the two handles simultaneously, the sampling body can also be lifted steadily.
[0034] In this embodiment, as Figures 1 to 3 shown, a handle sleeve 4 is fixed on the outer side wall of the sampling body 1. The handle sleeve 4 is specifically fixed on the sampling body 1 by welding; of course, the sampling body 1 and the handle sleeve 4 can also be an integral structure. A fixing hole is opened on the handle sleeve 4, and after the head end of the handle rod 2 is inserted into the handle sleeve 4, it is fixed through the fixing hole and screws / bolts.
[0035] Moreover, as Figure 1 and Figure 2As shown, the bottom diameter r of the sampling groove is 70 mm, the notch diameter R of the sampling groove is 140 mm, and the groove height h of the sampling groove is 210 mm. When the sampling groove of this size is full of samples, the sample weight can be lifted by regular operators. Of course, the bottom diameter, notch diameter, and groove height of the sampling groove can also be other values.
[0036] In addition, the handle is rectangular, the length of the handle is 100 mm, and the width of the handle is 30 mm. This size is convenient for lifting the handle. Of course, in other embodiments, the handle can also be circular or oval, which is also within the protection scope of the present utility model.
[0037] Furthermore, as Figure 1 and Figure 2 shown, the shapes of the sampling body 1 and the sampling groove correspond to each other, both are frustum-shaped. The included angle θ between the sleeve 4 and the outer side wall of the sampling body 1 is 77.1°, the lower side line length m of the sleeve 4 is 100 mm, the inner diameter of the sleeve 4 is 36 mm, the distance n between the upper part at the connection position of the sleeve 4 and the sampling body 1 and the upper end of the sampling body 1 is 70 mm, and the length L of the handle rod 2 is 170 mm, and the diameter of the handle rod 2 is 35 mm. The sampler of this size has better practicability. In addition, the wall thickness of the sampling groove is 1.5 mm to 2 mm. This thickness not only ensures the strength of the sampling body but also prevents the sampling body from being too heavy.
[0038] In this embodiment, an anti-rust paint is coated on the inner side wall of the sampling body to prevent the inner side wall of the sampling body from rusting. A metal paint is coated on the outer side wall of the sampling body, which can not only make the sampling body more beautiful but also facilitate the cleaning of the outer side wall of the sampling body.
[0039] In addition, an anti-corrosion paint is coated on the handle rod to prevent the handle rod from being corroded during long-term use.
[0040] In addition, an anti-slip sleeve is sleeved on the tail end and / or the middle part of the handle rod, and the handle rod can be held more stably through the anti-slip sleeve.
[0041] The above is only the specific implementation manner of the present utility model. Under the above teaching of the present utility model, those skilled in the art can make other improvements or deformations based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present utility model, and the protection scope of the present utility model should be subject to the protection scope of the claims.
