Description
Technical Field
[0001] The invention relates to the technical field of concrete sampling devices, in particular to a sampling device for concrete production detection. Background Art
[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is made of cement, sand and gravel aggregates and water in a certain proportion, and is formed after being stirred and mixed by a mixing device. Concrete is currently the most widely used and artificially prepared building material in the world. Cement concrete is obtained by mixing, and it is widely used in civil engineering. Concrete has the characteristics of high compressive strength, good durability, and a wide range of strength grades. When concrete is produced, the staff needs to take samples and then test it to determine whether the concrete meets the standards, so a sampling device is needed.
[0003] Chinese patent application document CN113432910A discloses a sampling device for concrete production detection, wherein the bottom end of a transparent sampling tube is set as a blocking structure, the top end of the transparent sampling tube is connected and fixed with a conical cover, a sealing rubber ring is bonded and fixed to the top of the conical cover, a sealing sliding sleeve in the transparent sampling tube is provided with a limit block, an air vent is provided at the bottom of the left inner wall of the transparent sampling tube, the limit block is located above the air vent, a scale line is provided on the front side of the transparent sampling tube, the scale line matches the limit block, and a guide rod is fixedly connected to the bottom of the limit block; the patent has a reasonable design, which is convenient for adjusting the position of the limit block according to the amount of concrete to be obtained, so that the amount of concrete obtained can be effectively controlled to achieve quantitative sampling, and it is convenient to cover the transparent sampling tube after sampling is completed and pour the excess concrete into the mixer, thereby reducing the waste of concrete and meeting the use requirements; However, when the discharge valve of the mixing barrel is opened, a large amount of concrete will be discharged due to the large inner diameter of its outlet, but only a small dose is needed for actual sampling, resulting in a waste of concrete. In addition, it is impossible to sample multiple positions of the mixing barrel, resulting in single sampling, and it is impossible to sample the concrete in the mixing barrel evenly, which causes deviations in the data of subsequent experiments and has great limitations in use.

[0021] Embodiment 2 This embodiment further defines the collecting component 6 on the basis of the first embodiment, so as to achieve the purpose of uniformly collecting concrete by utilizing the cooperation between the collecting component 6 and the receiving component 4 .
[0022] Specifically, Figure 7 As shown, the transmission shaft 60 includes a transmission shaft 60 fixedly connected to the output end of the motor 11, the transmission shaft 60 passes through the No. 1 gear 12 and does not contact the No. 1 gear 12, and a bevel gear 2 601 meshing with the bevel gear 1 471 is fixed on the upper end of the transmission shaft 60. Through the meshing bevel gear 2 601 and the bevel gear 1 471, when the transmission shaft 60 rotates, the bevel gear 1 471 rotates with the transmission circular plate 470, and the outer surface of the transmission shaft 60 is fixed with a positioning circular plate 61, a fixing circular plate 62 and a mounting disc 64 in sequence from top to bottom; The upper end of the positioning circular plate 61 is provided with a plurality of matching holes 610 in an annular array, the matching holes 610 match the drop tube 49, the matching holes 610 are communicated with the inner cavity of the drop tube 49, when the matching holes 610 are rotated to communicate with the inner cavity of the drop tube 49, the concrete in the drop tube 49 can fall downward, and the inner diameter of the drop tube 49 is the same as the diameter of the matching holes 610, the upper end of the fixed circular plate 62 is fixed with a plurality of flat-topped cone tubes 63 adapted to the matching holes 610 in an annular array, and the upper end of the fixed circular plate 62 is provided with a plurality of flat-topped cone tubes 63 adapted to the matching holes 610.

The upper end of the mounting disc 64 is provided with a plurality of sampling components 65 in an annular array, the sampling components 65 are fixedly connected to the mounting disc 64, and the mounting disc 64 is rotatably connected to the bearing plate 1. A plurality of clamping blocks 655 are adapted to the plurality of flat-top cone tubes 63, and the concrete passing through the flat-top cone tubes 63 will fall into the sampling components 65; Further, if Figure 8 As shown, the sampling component 65 includes a sampling barrel 650 fixed to the upper end of the mounting disc 64. The inner cavity of the sampling barrel 650 is used to receive concrete dropped from the drop pipe 49. The lower end of the sampling barrel 650 is provided with a reciprocating screw 652 penetrating the inner cavity of the sampling barrel 650. The reciprocating screw 652 is rotatably connected to the sampling barrel 650 at the penetration point, and the thread position of the reciprocating screw 652 is in the inner cavity of the sampling barrel 650. The lower end of the sampling barrel 650 is fixed with a second gear 653 meshing with the first gear 12. When the reciprocating screw 652 rotates with the mounting disc 64, the first gear 12 is engaged with the second gear 653. 12 can make the second gear 653 rotate, so as to make the reciprocating screw 652 rotate. A bevel column 651 is fixed to the inner cavity of the sampling barrel 650. The reciprocating screw 652 penetrates the bevel column 651 and is movably connected to the bevel column 651. A discharge port is provided on the outer surface of the sampling barrel 650 away from the transmission shaft 60. The rotation of the reciprocating screw 652 does not cause the bevel column 651 to rotate. In addition, the upper end of the bevel column 651 is an inclined surface, so that the concrete on its upper side will gather toward the discharge port. The outer surface of the reciprocating screw 652 is provided with a stirring component 654 which is slidably connected to the inner cavity of the sampling barrel 650.

[0023] Further, if Fig. 9As shown, the stirring component 654 includes a connecting pipe 6540 threadedly connected to the reciprocating screw 652. The connecting pipe 6540 can reciprocate up and down as the reciprocating screw 652 rotates. A stirring frame 6541 is fixed to the outer surface of the connecting pipe 6540. The stirring frame 6541 is a prior art and is used to stir the concrete in the inner cavity of the sampling barrel 650. The upper and lower ends of the connecting pipe 6540 are both rotatably provided with mounting rings 6542. The outer surfaces of the two mounting rings 6542 are fixed with connecting rings 6543 that are slidably connected to the inner wall of the sampling barrel 650 through multiple connecting columns. The connecting columns are connected between the outer surface of the mounting rings 6542 and the inner surface of the connecting rings 6543. The connecting ring 6543 is slidably connected to the inner cavity side wall of the sampling tube 650, so that when the connecting tube 6540 moves, the connecting ring 6543 can also move up and down on the inner cavity side wall of the sampling tube 650. Scraper rings 6544 are fixed at both upper and lower ends of the two connecting rings 6543. The scraper ring 6544 is concave on the side away from the connected connecting ring 6543, so that when the scraper ring 6544 moves on the inner cavity side wall of the sampling tube 650, the concrete on the inner cavity side wall of the sampling tube 650 can be scraped off. Among them, a hemispherical block 6545 is fixed to the upper end of the upper side mounting ring 6542, and the hemispherical block 6545 prevents concrete from accumulating on the upper end of the upper side mounting ring 6542.
[0024] It should be noted that the motor 11, universal wheel 2, telescopic rod 450, multi-stage cylinder 5 and stirring frame 6541 in the present invention are all prior arts, and their installation methods and control methods are also conventional designs, which will not be elaborated in detail in the present invention.
[0025] Specific implementation of the device: This device is a sampling device for concrete production testing, which can uniformly sample concrete and sample concrete in multiple layers in the mixing barrel to avoid limitations in later testing. Figure 4 and Fig.10 As shown, first push the device downward to the mixing barrel to be inspected, so that the material receiving component 4 is located under the discharge valve, and then open the discharge valve to take samples; The concrete falls into the inner cavity of the receiving box 40, and the concrete falling on the inclined surface of the receiving block 41 flows along the inclined surface to the space between the two stoppers 43, and the concrete falling on the two stoppers 43 flows along its own inclined surface to the space between the two stoppers 43, and then the pushing block 42 starts to reciprocate under the action of the multi-stage cylinder 5, pushing the concrete between the two stoppers 43 to the connection between the front receiving box 40 and the discharge pipe 48, so that the concrete is pushed into the inner cavity of the discharge pipe 48, and then flows along the discharge pipe 48 to the inner cavity of the drop pipe 49; The receiving box is used to receive concrete discharged from the mixing barrel discharge valve more than 40 times, and samples can be taken from multiple locations of the mixing barrel, increasing the diversity of sampling and improving the accuracy of the test results; When the pushing block 42 reciprocates, it moves forward and does not move out from the lower end of the receiving block 41. At this time, the concrete flowing on the receiving block 41 and the stopper 43 will fall on the upper end of the pushing block 42, and then it moves backward, using the inclined surface of the receiving block 41 to scrape off the concrete, and fall between the two stoppers 43, and then continue to push; Next, the motor 11 starts to rotate the transmission shaft 60, and the bevel gear 2 601 and the bevel gear 1 471 at the upper end of the transmission shaft 60 mesh with each other, so the bevel gear 1 471 also rotates when the transmission shaft 60 rotates. Since the bevel gear 1 471 and the transmission circular plate 470 are connected by a belt, the transmission circular plate 470 can rotate with the connecting plate 472, thereby moving the matching circular plate 473 up and down in the inner cavity of the drop tube 49, scraping off the concrete on the side wall of the inner cavity of the drop tube 49 and dropping it into the inner cavity of the matching hole 610 on the lower side. Only when the inner cavities of the drop tube 49 and the matching hole 610 are connected, the matching circular plate 473 will scrape off the concrete on the side wall of the inner cavity of the drop tube 49. Then, driven by the transmission shaft 60, the mounting disc 64, the fixed circular plate 62 and the locking circular plate 61 rotate at the same time, so the concrete passing through the matching hole 610 will fall from the flat-top cone tube 63 on the lower side into the corresponding inner cavity of the sampling tube 650. The mounting disc 64 rotates with the multiple sampling components 65, so the concrete falling from the drop tube 49 will continuously fall into the inner cavities of different sampling tubes 650, so that the multiple sampling tubes 650 can evenly collect the concrete at different positions in the mixing barrel, providing sufficient samples for the experiment, and multiple samples can be taken, which is convenient for multiple tests and improves the accuracy of the test results of the device; When the mounting disc 64 rotates with the multiple sampling components 65, the second gear 653 at the lower end of the reciprocating screw 652 rotates around the first gear 12, so that the second gear 653 can rotate with the reciprocating screw 652. When the reciprocating screw 652 rotates, the stirring component 654 on the surface of the reciprocating screw 652 can stir the concrete in the inner cavity of the sampling barrel 650 to prevent the concrete from solidifying in the inner cavity of the sampling barrel 650. During the reciprocating movement of the stirring member 654 on the surface of the reciprocating screw 652, the connecting tube 6540 moves up and down with the reciprocating screw 652, but its movement process is rotational, so the stirring frame 6541 on its outer surface stirs the concrete in the inner cavity of the sampling tube 650, and then the connecting ring 6543 connected by the two mounting rings 6542 through the connecting column moves with the movement of the connecting tube 6540, so that the scraping rings 6544 at the upper and lower ends of the connecting ring 6543 scrape the concrete on the side wall of the inner cavity of the sampling tube 650 to prevent the concrete from solidifying on the side wall, and also facilitate the later cleaning, and then pull the card plate 656 between the two card blocks 655, so that the concrete can flow from the inclined surface of the bevel column 651 to the discharge port, and then be discharged for detection; Finally, after the sampling is completed, the handwheel at the upper end of the screw rod 46 is turned to rotate the screw rod 46, and then the connecting block 45 moves downward on the surface of the screw rod 46, so that the telescopic rod 450 moves downward with the scraper plate 451, and through the mutual contact between the inclined surfaces of the scraper plate 451 and the connecting block 41, the scraper plate 451 can push the concrete remaining on the inclined surface of the connecting block 41 along the inclined surface of the connecting block 41 to between the two blocks 43, so as to facilitate the cleaning later.
