Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing equipment, specifically a concrete air content testing device. Background Technology

[0002] Concrete air content testing equipment is used to measure the air content in the mixture. Concrete can be divided into two components: coarse aggregate and mortar. The size of the coarse aggregate particles has almost no direct effect on the air content. The introduced air bubbles are distributed in the fine particles of the concrete, i.e., the mortar, and determine the overall performance of the concrete by affecting the performance of the mortar. Therefore, it is necessary to test the air content in the concrete. The sampled concrete is placed inside the testing equipment, water is added according to the ratio of water to concrete, and the concrete is stirred. The air content of the concrete is then measured by the testing equipment.

[0003] An existing patent (publication number: CN222232454U) discloses a concrete air content testing device. When using this device, it is necessary to manually tamp the concrete into the tank and use a rubber hammer to strike the outside of the tank to compact the concrete and reduce the air accumulated inside the concrete. This manual operation is time-consuming and labor-intensive, reducing the testing efficiency. Utility Model Content

[0004] The present invention aims to provide a concrete air content testing device that can automatically impact the side wall of the tank while mixing concrete, thereby reducing the air inside the concrete and improving the testing accuracy.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A concrete air content testing device, comprising:

[0007] The tank body has a detachable cover on its top, and a measuring instrument is mounted on the cover.

[0008] The first rotating shaft is rotatably connected inside the tank and is arranged horizontally. Multiple stirring rods are fixedly connected to the outer surface of the first rotating shaft. One end of the first rotating shaft passes through the tank and is fixedly connected to a driving wheel. A driven wheel is engaged on the outer surface of the driving wheel.

[0009] A bracket is fixedly connected to the side wall of the tank. An elastic rod is fixedly connected to the side of the bracket near the tank, and an impact element is fixedly connected to the other end of the elastic rod.

[0010] The second rotating shaft is rotatably connected to the bracket. The bottom end of the second rotating shaft is fixedly connected to the driven wheel, and a cam is fixedly installed in the middle of the second rotating shaft. An arc-shaped part adapted to the cam is fixedly installed on the side wall of the impactor.

[0011] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0012] When testing is required, first open the lid, add concrete coarse material and water into the tank according to the ratio, then close the lid, start the motor to drive the first rotating shaft to rotate, which in turn drives the mixing rod to rotate, thereby mixing the concrete and making the air content detection of the concrete inside the tank more accurate. When the first rotating shaft rotates, it drives the drive wheel to rotate, which in turn drives the driven wheel to rotate, causing the second rotating shaft to rotate. When the second rotating shaft rotates, it drives the cam to rotate. At this time, the cam will squeeze the arc-shaped part, thereby driving the impact part to move and impact the tank. When the cam continues to rotate and stops squeezing the arc-shaped part, the impact part will be reset under the elastic force of the elastic rod. This process is repeated, that is, continuously impacting the tank. This method can vibrate the concrete inside the tank, thereby reducing the air trapped in the concrete and further improving the accuracy of concrete air content detection. Moreover, the impact occurs while the concrete is being mixed, eliminating the need for manual tamping of the concrete and tapping the outer surface of the measuring bowl with a rubber hammer, saving time and labor.

[0013] In a preferred embodiment, the present invention can be further configured such that: the first rotating shaft is rotatably connected to the tank body via a bearing, and a motor is fixedly connected to the end of the first rotating shaft away from the drive wheel, and the motor is fixedly installed on the side wall of the tank body.

[0014] In a preferred embodiment, the present invention can be further configured such that both the driving wheel and the driven wheel are bevel gears.

[0015] In a preferred embodiment, the present invention can be further configured such that there are two elastic rods, and the two elastic rods are fixed to the bracket in a mirror-symmetrical manner.

[0016] In a preferred embodiment, the present invention can be further configured such that: the impact member includes a plate fixedly connected to the end of the elastic rod, and a plurality of push rods are fixedly connected to the side wall of the plate, the push rods acting on the side wall of the tank.

[0017] In a preferred embodiment, the present invention can be further configured such that the second rotating shaft is rotatably connected to the bracket via a bearing, and the second rotating shaft is perpendicular to the first rotating shaft.

[0018] In a preferred embodiment, the present invention can be further configured such that the arc-shaped member has an arc-shaped groove adapted to the cam on the side near the cam.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0021] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0022] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxyacetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0023] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0024] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0025] In this invention, the first rotating shaft and the stirring rod can automatically mix the concrete, making the detection of air content in the concrete inside the tank more accurate. Furthermore, by utilizing the cooperation of the cam, impact component, driving wheel, driven wheel and other structures, the tank can be continuously impacted, thereby causing the concrete inside the tank to vibrate, thus reducing the air trapped in the concrete and further improving the accuracy of the concrete air content detection. The operation is simple and saves time and effort. Attached Figure Description

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0032] Based on the concept of this application, combined with Figures 1 to 3 This document describes an embodiment of a concrete air content testing device for detecting the air content of concrete. Specifically, the device is constructed as an integrated structure, comprising four components: a tank 1, a first rotating shaft 4, a support 8, and a second rotating shaft 11. The first rotating shaft 4, in conjunction with a stirring rod 5, automatically mixes the concrete, making the detection of air content within the tank 1 more accurate. Furthermore, the device utilizes the coordinated structure of a cam 12, an impact element 10, a driving wheel 6, and a driven wheel 7 to continuously impact the tank 1, thereby vibrating the concrete inside and reducing air trapped within it. This further improves the accuracy of the air content detection, and the device is simple to operate, saving time and effort.

[0033] Combination Figures 1-3 As shown, the present invention provides a concrete air content testing device, comprising:

[0034] Tank 1, with a detachable cover 2 on the top of the tank 1, and a measuring instrument 3 installed on the cover 2;

[0035] The first rotating shaft 4 is rotatably connected inside the tank 1 and is horizontally arranged. Multiple stirring rods 5 are fixedly connected to the outer surface of the first rotating shaft 4. One end of the first rotating shaft 4 passes through the tank 1 and is fixedly connected to the driving wheel 6. The outer surface of the driving wheel 6 is engaged with the driven wheel 7.

[0036] The bracket 8 is fixedly connected to the side wall of the tank 1. An elastic rod 9 is fixedly connected to the side of the bracket 8 closest to the tank 1, and an impact member 10 is fixedly connected to the other end of the elastic rod 9.

[0037] The second rotating shaft 11 is rotatably connected to the bracket 8. The bottom end of the second rotating shaft 11 is fixedly connected to the driven wheel 7, and a cam 12 is fixedly installed in the middle of the second rotating shaft 11. An arc-shaped part 13 adapted to the cam 12 is fixedly installed on the side wall of the impact member 10.

[0038] Regarding the technical solution of this embodiment, the first rotating shaft 4 is rotatably connected to the tank body 1 through a bearing, and a motor 14 is fixedly connected to the end of the first rotating shaft 4 away from the drive wheel 6. The motor 14 is fixedly installed on the side wall of the tank body 1 and is powered by an external power source. When concrete coarse material and water are put into the tank body 1 in proportion, the motor 14 is started to drive the first rotating shaft 4 to rotate, which in turn drives the stirring rod 5 to rotate, thereby mixing the concrete and making the detection of air content in the concrete inside the tank body 1 more accurate.

[0039] In this embodiment, both the driving wheel 6 and the driven wheel 7 are bevel gears. When the first rotating shaft 4 rotates, it will drive the driving wheel 6 to rotate, thereby driving the driven wheel 7 to rotate.

[0040] In this embodiment, there are two elastic rods 9, and the two elastic rods 9 are fixed on the bracket 8 in a mirror-symmetrical manner. The elastic rods 9 are used to provide elastic force to the impact member 10, so as to drive the impact member 10 to reset.

[0041] Regarding the technical solution of this embodiment, the impact member 10 includes a plate 101 fixedly connected to the end of the elastic rod 9. A plurality of top rods 102 are fixedly connected to the side wall of the plate 101. The top rods 102 are made of rubber and act on the side wall of the tank 1. When the top rods 102 on the impact member 10 impact the side wall of the tank 1, the concrete inside the tank 1 can vibrate, thereby reducing the air trapped in the concrete and further improving the accuracy of the air content detection of the concrete. Moreover, the impact is carried out while the concrete is being mixed, eliminating the need for manual tamping of the concrete and tapping the outer surface of the measuring bowl with a rubber hammer, saving time and effort.

[0042] Regarding the technical solution of this embodiment, the second rotating shaft 11 is rotatably connected to the bracket 8 through a bearing, and the second rotating shaft 11 is perpendicular to the first rotating shaft 4. When the driven wheel 7 rotates, it will drive the second rotating shaft 11 to rotate. When the second rotating shaft 11 rotates, it will drive the cam 12 to rotate. At this time, the cam 12 will squeeze the arc-shaped part 13, thereby driving the impacting part 10 to move and impact the tank 1. When the cam 12 continues to rotate and stops squeezing the arc-shaped part 13, the impacting part 10 will be reset under the elastic force of the elastic rod 9. This process is repeated, that is, the impacting part 1 is continuously impacted.

[0043] Regarding the technical solution of this embodiment, the arc-shaped component 13 has an arc-shaped groove adapted to the cam 12 on the side near the cam 12.

[0044] Specifically, when testing is required, first open the cover 2, add concrete coarse material and water into the tank 1 according to the ratio, then close the cover 2, start the motor 14 to drive the first rotating shaft 4 to rotate, which in turn drives the stirring rod 5 to rotate, thereby mixing the concrete and making the air content detection of the concrete inside the tank 1 more accurate. When the first rotating shaft 4 rotates, it drives the drive wheel 6 to rotate, which in turn drives the driven wheel 7 to rotate, causing the second rotating shaft 11 to rotate accordingly. When the second rotating shaft 11 rotates, it drives the cam 12 to rotate. At this time, the cam 12 will move the arc-shaped part 13. The compression causes the impactor 10 to move and impact the tank 1. When the cam 12 continues to rotate and stops compressing the arc-shaped part 13, the impactor 10 will reset under the elastic force of the elastic rod 9. This process is repeated continuously, which can cause the concrete inside the tank 1 to vibrate, thereby reducing the air trapped in the concrete and further improving the accuracy of concrete air content detection. Moreover, the impact occurs while the concrete is being mixed, eliminating the need for manual tamping of the concrete and tapping the outer surface of the measuring bowl with a rubber hammer, saving time and effort.

[0045] The present invention provides a concrete air content testing device in further detail below with reference to the accompanying drawings and embodiments.

[0046] A concrete air content testing device, comprising:

[0047] Tank 1, with a detachable cover 2 on the top of the tank 1, and a measuring instrument 3 installed on the cover 2;

[0048] The first rotating shaft 4 is rotatably connected inside the tank 1 and is horizontally arranged. Multiple stirring rods 5 are fixedly connected to the outer surface of the first rotating shaft 4. One end of the first rotating shaft 4 passes through the tank 1 and is fixedly connected to the driving wheel 6. The outer surface of the driving wheel 6 is engaged with the driven wheel 7.

[0049] The bracket 8 is fixedly connected to the side wall of the tank 1. An elastic rod 9 is fixedly connected to the side of the bracket 8 closest to the tank 1, and an impact member 10 is fixedly connected to the other end of the elastic rod 9.

[0050] The second rotating shaft 11 is rotatably connected to the bracket 8. The bottom end of the second rotating shaft 11 is fixedly connected to the driven wheel 7, and a cam 12 is fixedly installed in the middle of the second rotating shaft 11. An arc-shaped part 13 adapted to the cam 12 is fixedly installed on the side wall of the impact member 10.

[0051] The working principle and usage process of this utility model are as follows: When testing is required, first open the cover 2, add concrete coarse material and water into the tank 1 according to the ratio, then close the cover 2, start the motor 14 to drive the first rotating shaft 4 to rotate, which in turn drives the stirring rod 5 to rotate, thereby mixing the concrete and making the air content detection of the concrete inside the tank 1 more accurate. When the first rotating shaft 4 rotates, it will drive the driving wheel 6 to rotate, which in turn drives the driven wheel 7 to rotate, causing the second rotating shaft 11 to rotate accordingly. When the second rotating shaft 11 rotates, it will drive the cam 12 to rotate. At this time, the cam 12 will squeeze the arc-shaped part 13, from... The impactor 10 moves and impacts the tank 1. When the cam 12 continues to rotate and stops pressing the arc-shaped part 13, the impactor 10 will reset under the elastic force of the elastic rod 9. This process is repeated continuously, which can cause the concrete inside the tank 1 to vibrate, thereby reducing the air trapped in the concrete and further improving the accuracy of concrete air content detection. The impact is carried out while the concrete is being mixed, eliminating the need for manual tamping of the concrete and tapping the outer surface of the measuring bowl with a rubber hammer. This saves time and effort, and the air content of the concrete can then be measured using the measuring instrument 3.
