Description

Technical Field

[0001] This utility model relates to the field of building engineering technology and discloses a sand and gravel mixing device for producing carbonation-resistant concrete. Background Technology

[0002] The background technology of sand and gravel mixing equipment for producing carbonation-resistant concrete mainly involves the material mixing process in concrete production, the need to improve carbonation resistance, and the limitations of traditional mixing equipment. Nowadays, many mixers can be seen on construction sites to mix sand and gravel. If the sand, gravel, cementitious materials, and admixtures are not mixed evenly, it will lead to weak local carbonation resistance. Therefore, the mixing equipment must ensure a highly uniform distribution of materials.

[0003] Most existing products are drum-type mixers. The required materials are added in proportion at the inlet, and a motor drives the mixing rods, which in turn drive the mixing blades to stir the materials. This continuous cutting and mixing achieves the desired blending effect. After mixing, the materials are transported to the outlet for disposal. This process achieves the mixing effect, and this type of device is very common today. However, its drawbacks are also obvious. The cutting is not uniform enough. Cutting and mixing are crucial factors in the entire process, so some mixers are further processed with reverse mixing blades to reduce cutting dead zones. This does improve cutting efficiency, but it's insufficient for mixing concrete materials. For materials with larger particles, it still cannot achieve uniform mixing. Furthermore, when the mixing blades rotate, concrete material is thrown onto the outer wall by the centrifugal force. Over time, this residue accumulates on the outer wall, making cleaning difficult and damaging the device, thus reducing its lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sand and gravel mixing device for the production of carbonation-resistant concrete, which aims to solve the problems of material adhering to the wall and uneven material mixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand and gravel mixing device for producing anti-carbonation concrete, comprising a mixer shell, a support rod fixedly connected inside the mixer shell, a motor fixedly connected to the upper surface of the support rod, a mixing rod fixedly connected to the output end of the motor, an upper mixing blade fixedly connected to the outer wall of the mixing rod, a lower mixing blade fixedly connected to the outer wall of the mixing rod, a connecting rod fixedly connected inside the mixing rod, a fixing block 1 fixedly connected to the upper surface of the connecting rod, a fixing block 2 fixedly connected to the upper surface of the connecting rod, a scraper 1 slidably connected inside the fixing block 1, and a quick-release assembly installed on one side of the outer wall;

[0006] The quick-release assembly includes a clamping shell, one side of the outer wall of the clamping shell is fixedly connected to one side of the outer wall of a fixing block, a support block is slidably connected inside the clamping shell, a clamping rod is fixedly connected to one side of the outer wall of the support block, the outer wall of the clamping rod passes through the fixing block and is slidably connected inside the scraper, a spring is provided on one side of the inside of the clamping shell, a spring is provided on one side of the outer wall of the clamping rod, and a movable buckle is rotatably connected inside the clamping shell.

[0007] Furthermore, a conical outer shell is fixedly connected to the lower surface of the mixer shell, and a lower scraper is fixedly connected to the lower surface of the stirring rod, with the outer wall of the lower scraper rotatably connected to the inner wall of the conical outer shell.

[0008] Furthermore, a collecting shell is fixedly connected to the lower surface of the conical shell, and a motor is fixedly connected to the outer surface of the collecting shell.

[0009] Furthermore, an auger blade is fixedly connected inside the collecting shell, an auger blade is fixedly connected to the motor output end, a support leg is fixedly connected to the lower surface of the conical shell, and the outer wall is rotatably connected to the inner wall.

[0010] Furthermore, the outer wall of the first scraper is rotatably connected to the mixer housing, and the inner wall of the mixer housing is rotatably connected to the second scraper.

[0011] Furthermore, one end of the spring is fixedly connected to one side of the inner wall of the clamping housing 23, and the other end of the spring is fixedly connected to the support block.

[0012] Furthermore, one end of the movable buckle is slidably connected to the inside of the clamping rod, and the other end of the movable buckle is slidably connected to the inside of the support block.

[0013] Furthermore, one end of the second spring is fixedly connected to one side inside the support block, and the other end of the second spring is fixedly connected to the lower surface of the clamping rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, pressing the support block drives the second spring, which in turn drives the movable buckle, thereby driving the clamping shell and thus the first spring. The counterforce of the first spring eliminates the pressure on the first fixed block, allowing the clamping rod to be pulled out, thus popping out the quick-release assembly. This achieves the separation of the first baffle and the first fixed block, allowing the first baffle to be cleaned and replaced. After replacing the baffle with the new one, the clamping rod passes through the baffle and the fixed block. Pressing the support block again compresses the second spring, which in turn drives the movable buckle, squeezing the clamping shell. Then, the spring is repressed, causing it to press on the first fixed block again, thus fixing the first fixed block and the new baffle. This achieves the purpose of replacing the baffle, solves the problem of residual material on the inner wall of the device, cleans the baffle, and improves the lifespan of the device.

[0016] 2. In this utility model, the auger blade is driven to rotate by the output end of the motor, thereby generating cutting force and then processing it again. The material that has been cut and stirred once is then cut and stirred a second time. When the raw material enters the device, the upper and lower stirring blades work together to stir the raw material. However, it is difficult to cut large molecular materials. They can only be reduced to smaller sizes, which is difficult to process further. But when the material enters the auger blade, it is reduced to a smaller volume and can be processed a second time to stir it more evenly. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides an embodiment of a sand and gravel mixing device for producing anti-carbonation concrete, comprising a mixer housing 1. A support rod 3 is fixedly connected to one side of the upper part of the mixer housing 1 to frame the entire device structure. The support rod 3 supports a motor 2, providing power to the entire mixing device. The motor 2, in conjunction with the mixing rod 9, rotates to achieve the function of cutting and mixing the materials. The mixing rod 9, in conjunction with the upper mixing blade 6, performs initial cutting and mixing on the upper part of the device. The mixing rod 9, in conjunction with the lower mixing blade 18, performs secondary cutting and mixing on the middle part of the device. The stirring mechanism, in conjunction with the connecting rod 12 and the stirring rod 9, supports the interior of the device, acting as a stabilizing device. The connecting rod 12, together with the fixing block 11 and the fixing block 22, also acts as a stabilizing device, allowing it to rotate with the stirring rod 9. The fixing blocks 11 and 22, together with the scraper 10 and the scraper 21, rotate to scrape the material from the inner wall, acting as a cleaning device and reducing material loss. The fixing blocks, along with the quick-release device, allow for rapid disassembly of the fixing blocks 11 and 22, improving disassembly efficiency and solving the problem of baffle damage.

[0027] The clamping housing 23 is used to fix the entire disassembly device, which protects the inside of the disassembly device from being affected. The support block 15 and the clamping rod 20 slide together to connect the fixing block 11 and the scraper 10, making them easy to disassemble and replace. The clamping housing 23 and the spring 13 reciprocate to make the entire disassembly device more convenient. The clamping rod 20 and the spring 2 14 reciprocate to achieve the disassembly effect. The clamping housing 23 and the movable buckle 16 reciprocate to facilitate the disassembly of the device.

[0028] Reference Figure 3 and Figure 6 The mixer housing 1, together with the conical housing 7, supports the entire device, preventing damage from the external environment. The stirring rod 9, together with the lower scraper 17, performs a circular motion to clean the conical housing 7. The conical housing 7, together with the collection housing 19, connects the entire device, serving to protect it. The motor 4, together with the auger blade 8, rotates to cut and stir the materials, making them more uniform. The support leg 5 is used to raise the height of the entire device, thus leaving space underneath for the auger blade 8 to stir.

[0029] Working principle: When materials need to be mixed, pour them into the device according to the ratio, turn on motor 2, and the output of motor 2 drives the stirring rod 9 to rotate. The rotation of stirring rod 9 drives the upper stirring blade 6 and the lower stirring blade 18 to rotate, thereby cutting and mixing the materials. Stirring rod 9 is connected to connecting rod 12. Fixed block 11 and fixed block 22 are connected to the upper surfaces of both sides of connecting rod 12. Scraper 10 is slidably connected inside fixed block 11, and scraper 21 is slidably connected inside fixed block 22. This rotation of stirring rod 9 drives scraper 10 and scraper 21 to rotate, cleaning the inner surface of the mixer shell 1. The cleaning process involves continuous rotation, but prolonged rotation can damage the scraper 10. Therefore, a quick-release assembly was added to the scraper 10 and the fixing block 11. The clamping rod 20 is inserted into the fixing block 11 and the scraper 10. By pressing the clamping shell 15, the spring 2 14 is activated. The spring 2 14 drives the movable buckle 16 to rotate, which in turn drives the spring 1 13 to press and thus drive the support block 23. This, in turn, drives the fixing block 11 and the clamping rod 20, achieving the quick-release function. This allows for the rapid disassembly of the scraper 10, thus achieving the cleaning effect. The material will be hung down by the lower scraper 17 onto the inner surface of the lower conical shell 7 and discharged into the outlet.

[0030] After the material enters the discharge port, it flows into the auger blade 8 below. The auger blade 8 is fixedly connected to the output end of motor 4. Motor 4 generates electricity to drive the auger blade 8 to rotate, thereby agitating the material and making it more evenly mixed. Then, uniform concrete is discharged from the tail end of the auger blade 8.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
