Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a high-efficiency stirring device for concrete testing samples. Background Art

[0002] Concrete is widely used in civil engineering. It uses mixing equipment to bind cementitious materials and aggregates into an integral engineering composite material. Common concrete uses cement as the cementitious material, sand and gravel as aggregates, and is mixed with water and admixtures in a certain proportion.

[0003] Different projects require concrete of different strength grades, and testing the concrete strength before using it is a necessary workflow. Experimental concrete samples require accurate proportions and uniform composition. Given that the shape of concrete is time-sensitive, a dedicated laboratory concrete mixing device is usually required. However, existing concrete mixing devices usually pour the material directly from the discharge port, and then weigh and divide it into multiple groups of test samples for testing. This operation is cumbersome and affects the test efficiency. At the same time, there may be errors in the weighing process, resulting in different amounts of concrete test samples in each group, affecting the accuracy of the test results. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency stirring device for concrete test samples, which can intermittently discharge materials in a quantitative manner, is simple to operate, and is convenient for staff to quickly test samples, thereby helping to improve testing efficiency. It can also ensure that the amount of concrete test samples in each group of multiple groups of tests is the same, thereby improving the accuracy of the test results.

[0005] The embodiments of the present invention are implemented by the following technical solutions:

[0006] A high-efficiency mixing device for concrete testing samples comprises a mixing box and an intermittent discharging mechanism, wherein a mixing assembly is arranged in the mixing box, a discharging pipe is arranged at the lower part of the mixing box, a metering pump is arranged on the discharging pipe, the intermittent discharging mechanism comprises a base, a chuck, a shell, a storage box tube and an intermittent driving assembly, the chuck is mounted on the base through a rotating rod, the shell is mounted on the bottom of the chuck, a plurality of circular card slots are formed between the chuck and the inner side wall of the shell, the storage box tube is located above one card slot, a plurality of quantitative boxes are placed in the storage box tube, the quantitative boxes are clamped in the card slot, the outlet end of the discharging pipe is located above another card slot, and the intermittent driving assembly is used for driving the rotating rod to rotate.

[0007] Furthermore, the intermittent drive component includes an intermittent motion turntable, a continuous motion turntable and an intermittent motion motor. The intermittent motion turntable is fixedly mounted on the rotating rod. A plurality of limit slots are provided on the intermittent motion turntable. A limit column is provided on the continuous motion turntable. The limit column can be clamped in the limit slot. The output end of the intermittent motion motor is connected to the bottom of the continuous motion turntable through a rotating shaft.

[0008] Furthermore, the intermittent motion turntable is provided with a plurality of arcuate surfaces, the continuous motion turntable is crescent-shaped, the outer convex surface of the continuous motion turntable can contact the arcuate surface, and the limiting column is provided on the inner concave surface of the continuous motion turntable.

[0009] Furthermore, a discharge channel is provided on the shell, and a conveyor belt is provided on the discharge channel.

[0010] Furthermore, the storage box tube is connected to the outer side wall of the shell through a connecting plate.

[0011] Furthermore, the stirring assembly includes a stirring shaft and a plurality of stirring rods. The stirring shaft is connected to the output end of the stirring motor.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0014] The utility model stirs concrete in a mixing box with a stirring assembly, which can improve the uniformity of various components in the concrete. After stirring and mixing, the concrete is discharged from the discharge pipe at the bottom of the mixing box, and the material is quantitatively discharged by a metering pump. The operation is simple, which is convenient for the staff to quickly test the sample, and helps to improve the detection efficiency. An intermittent discharge mechanism is set, and the intermittent drive assembly is used to drive the rotating rod to rotate, and the rotation of the rotating rod drives the chuck to rotate. The rotation of the chuck causes the quantitative box in the slot to rotate on the shell. When the quantitative box rotates to the bottom of the discharge pipe, the concrete falls from the outlet end of the discharge pipe into the quantitative box, and the chuck continues to rotate. The quantitative box containing concrete is away from the discharge pipe, and another quantitative box on the chuck approaches the discharge pipe to continue to contain concrete, thereby realizing intermittent quantitative discharge, improving the discharge speed, ensuring that the concrete test sample quantity in each quantitative box is the same in multiple groups of comparative tests, and improving the accuracy of the test results. At the same time, when the concrete test sample quantity is a variable, it only needs to adjust the metering pump to obtain concrete with different sample quantities, which is more convenient for detection and more sufficient for detection data.

[0026] Example 1

[0027] like Figure 1-4 As shown, this embodiment provides a high-efficiency mixing device for concrete test samples, including a mixing box 1 and an intermittent discharging mechanism, wherein a mixing assembly is arranged in the mixing box 1, a discharging pipe 3 is arranged at the lower part of the mixing box 1, and a metering pump 4 is arranged on the discharging pipe 3, and the intermittent discharging mechanism comprises a base 5, a chuck 6, a shell 7, a storage box tube 8 and an intermittent driving assembly 9, the chuck 6 is mounted on the base 5 through a rotating rod 10, the shell 7 is mounted on the bottom of the chuck 6, the chuck 6 and the inner side wall of the shell 7 form a plurality of circular card grooves 11, the storage box tube 8 is located above a card groove 11, a plurality of quantitative boxes 12 are placed in the storage box tube 8, the quantitative boxes 12 are clamped in the card groove 11, the outlet end of the discharging pipe 3 is located above another card groove 11, and the intermittent driving assembly 9 is used to drive the rotating rod 10 to rotate.

[0028] Among them, the concrete is stirred in the mixing box 1 by a stirring assembly, which can improve the uniformity of each component in the concrete. After stirring and mixing, the concrete is discharged from the discharge pipe 3 at the bottom of the mixing box 1, and the material is quantitatively discharged by the metering pump 4. The operation is simple, which is convenient for the staff to quickly test the sample, and helps to improve the detection efficiency. An intermittent discharge mechanism is set, and the intermittent drive assembly 9 is used to drive the rotating rod 10 to rotate, and the rotation of the rotating rod 10 drives the chuck 6 to rotate. The rotation of the chuck 6 makes the quantitative box 12 in the slot 11 rotate on the shell 7, that is, the shell 7 does not rotate. When the quantitative box 12 rotates to the bottom of the discharge pipe 3, the concrete falls from the outlet end of the discharge pipe 3 into the quantitative box 12, and the chuck 6 continues to rotate. The quantitative box 12 containing concrete is away from the discharge pipe 3, and another quantitative box 12 on the chuck 6 approaches the discharge pipe 3 to continue to contain concrete, thereby realizing intermittent quantitative discharge, improving the discharge speed, ensuring that the amount of concrete test samples in each quantitative box 12 in multiple groups of comparative tests is the same, and improving the accuracy of the test results. At the same time, when the concrete test sample size is a variable, it is only necessary to adjust the metering pump 4 to obtain concrete with different sample sizes, so that the test data is more sufficient. Among them, multiple quantitative boxes 12 can be placed in the storage box tube 8. Initially, the quantitative box 12 at the bottom is clamped in a card slot 11. When the quantitative box 12 at the bottom moves under the rotation of the chuck 6, the top of the chuck 6 abuts against the bottom of the storage box tube 8. When the other card slot 11 formed by the chuck 6 and the inner side wall of the shell 11 moves to the lower part of the storage box tube 8, the quantitative box 12 in the storage box tube 8 falls into the card slot 11 again, thereby realizing the automatic feeding of the quantitative box 12 and improving the concrete discharging speed. In other embodiments, quantitative boxes 12 of different volumes can be placed in the storage box tube 8, so that test test data with the concrete sample size as a variable can also be obtained, which is highly practical. In detail, four arc-shaped notches are opened at equal intervals on the edge of the chuck 6, and the arc-shaped notches cooperate with the shell 7 to form a circular card slot 11.

[0029] In this embodiment, the intermittent drive assembly 9 includes an intermittent motion turntable 91, a continuous motion turntable 92 and an intermittent motion motor 93. The intermittent motion turntable 91 is fixedly mounted on the rotating rod 10. A plurality of limit slots 911 are provided on the intermittent motion turntable 91. A limit post 921 is provided on the continuous motion turntable 92. The limit post 921 can be clamped in the limit slot 911. The output end of the intermittent motion motor 93 is connected to the bottom of the continuous motion turntable 92 through a rotating shaft 94. A plurality of arcuate surfaces 912 are provided on the intermittent motion turntable 91. The continuous motion turntable 92 is crescent-shaped. The outer convex surface of the continuous motion turntable 92 can contact the arcuate surface 912. The limit post 921 is provided on the inner concave surface of the continuous motion turntable 92. The number of the arcuate surfaces 912 is the same as the number of the clamping slots 11. Initially, the outer convex surface of the continuous motion turntable 92 contacts an arc surface 912 on the intermittent motion turntable 91, and the intermittent motion motor 93 is started, and the intermittent motion motor 93 drives the continuous motion turntable 92 to rotate. When the continuous motion turntable 92 rotates, the limit column 921 on the continuous motion turntable 92 makes a circular motion. During the circular motion, the limit column 921 is stuck in a limit groove 911 and moves in the limit groove 911, thereby driving the intermittent motion turntable 91 to rotate. The movable turntable 91 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the chuck 6 to rotate, so that the chuck 6 drives the quantitative box 12 to move; when the limiting column 921 moves to a certain distance, the limiting column 921 leaves the limiting groove 911, the intermittent motion turntable 91 stops rotating, and the rotating rod 10 and the chuck 6 stop rotating at the same time, the quantitative box 12 on the chuck 6 moves to the bottom of the discharge pipe 3, and the metering pump 4 is started for quantitative discharge. This process is repeated to realize intermittent quantitative discharge, which is easy to operate and saves time and effort.

[0030] In this embodiment, the housing 7 is further provided with a discharge channel 13, and a conveyor belt 14 is provided on the discharge channel 13. The quantitative box 12 containing concrete is discharged through the discharge channel 13 and the conveyor belt 14, which can speed up the discharge speed, facilitate the staff to quickly detect it, and improve the detection efficiency.

[0031] In this embodiment, the storage box tube 8 is connected to the outer side wall of the housing 7 through a connecting plate 17. Wherein, the two ends of the connecting plate 17 are respectively fixed to the storage box tube 8 and the housing 7 by screws, so that the storage box tube 8 is convenient to install and disassemble.

[0032] In this embodiment, the stirring assembly includes a stirring shaft 15 and a plurality of stirring rods 16. The stirring shaft 15 is connected to the output end of the stirring motor 2. The stirring rods 16 are annularly mounted on the outer peripheral surface of the stirring shaft 15. The stirring motor 2 is mounted on the top of the stirring box 1. When materials are added into the stirring box 1, the stirring motor 2 is started, the stirring motor 2 drives the stirring shaft 15 to rotate, the stirring shaft 15 drives the stirring rods 16 to rotate, and the stirring rods 16 rotate to stir the materials, which can make the materials more evenly mixed, improve the quality of concrete, and facilitate detection.

[0033] In this embodiment, the stirring rod 16 includes a horizontal section and a bent section, one end of the horizontal section is connected to the stirring shaft 15, and the other end of the horizontal section is connected to the bent section. This can improve the stirring effect of the material, improve the mixing degree of the material, and improve the quality of the concrete.

[0034] The working principle of a high-efficiency mixing device for concrete testing samples is as follows: add various materials into the mixing box 1, start the mixing motor 2, the mixing motor 2 drives the mixing shaft 15 to rotate, the mixing shaft 15 drives the mixing rod 16 to rotate, the mixing rod 16 rotates to mix the materials, and after mixing, a uniformly mixed concrete is obtained. Concrete is quantitatively discharged from the discharge pipe 3 under the action of the metering pump 4. At the same time, the intermittent motion motor 93 is started, and the intermittent motion motor 93 drives the continuous motion turntable 92 to rotate. When the continuous motion turntable 92 rotates, the limit column 921 on the continuous motion turntable 92 performs a circular motion. During the circular motion, the limit column 921 will be stuck in a limit groove 911 and move in the limit groove 911, thereby driving the intermittent motion turntable 91 to rotate, the intermittent motion turntable 91 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the chuck 6 to rotate, so that the chuck 6 drives the quantitative box 12 to move; when the limit When the column 921 moves to a certain distance, the limiting column 921 leaves the limiting groove 911, the intermittent motion turntable 91 stops rotating, and the rotating rod 10 and the chuck 6 stop rotating at the same time. The quantitative box 12 on the chuck 6 moves to the bottom of the discharge pipe 3, and the concrete falls into the quantitative box 12 from the outlet end of the discharge pipe 3. The continuous motion turntable 92 continues to rotate to drive the intermittent motion turntable 91 to rotate, so that the chuck 6 continues to rotate, and the quantitative box 12 containing concrete moves away from the discharge pipe 3, and the other quantitative box 12 in the card slot 11 on the chuck 6 approaches the discharge pipe 3 and continues to contain concrete, and the cycle is repeated to achieve intermittent quantitative discharging.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
