Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, specifically to an anti-hanging structure for a gravel concrete retarder mixing device. Background Technology

[0002] Concrete retarders are additives that reduce the hydration rate and heat of hydration of cement or gypsum, thus prolonging the setting time. They are added to the concrete during the mixing and preparation process to ensure uniform mixing with the concrete raw materials. In practical use, a phenomenon often occurs where some concrete residue remains on the inner wall of the equipment after unloading. The causes of this phenomenon are complex. On the one hand, concrete itself has a certain degree of viscosity, especially after the addition of a retarder, its physical properties change, further increasing its viscosity, causing it to easily adhere to the inner wall of the equipment during unloading.

[0003] This inverted phenomenon poses a significant threat to the equipment. If the residual concrete is not cleaned quickly, it will harden and form lumps on the inner wall, abrading the inner wall and reducing its lifespan. Furthermore, the hardened concrete lumps can affect the normal operation of internal mixing and conveying components, leading to equipment malfunctions, increased maintenance costs and downtime, and ultimately severely impacting production efficiency. Therefore, after each unloading operation, staff need to thoroughly clean the inner wall of the mixing tank. However, the complex and enclosed internal structure of the mixing tank makes direct cleaning of its interior difficult. Utility Model Content

[0015] Compared with the prior art, this utility model provides an anti-hanging structure for a gravel concrete retarder mixing device, which has the following beneficial effects:

[0016] 1. This gravel concrete retarder mixing device uses an anti-inverted structure. Through the set lifting mechanism, the operator only needs to start the stepper motors on the front and rear sides to drive multiple threaded drums to rotate synchronously. By controlling the synchronous up and down movement of multiple threaded rods, the up and down movement of the top cover is controlled, which makes it easy for the operator to adjust the opening and closing state of the top cover. At the same time, the easy opening and closing of the mixing tank and the top cover also allows the overall structure of the mixing mechanism to be moved directly above the mixing tank, so that the operator can directly flush and clean the inner wall and internal structure of the mixing tank and the top cover. The operation is simple and convenient for the operator to use.

[0017] 2. This gravel concrete retarder mixing device uses an anti-hanging structure. Through the mixing mechanism, after the drive motor starts and the mixing rod mixes the concrete material in the mixing tank, the material remaining in the mixing tank and the inner wall of the top cover after the concrete is discharged is cleaned from top to bottom by the rotation of the L-shaped top wall scraper and the angled scraper. This causes the residual material to fall to the bottom of the mixing tank, and finally, the material is pushed into the discharge port by the rotation of the arc-shaped scraper. This completes the self-cleaning of the inverted material in the mixing tank, reducing the workload of the staff when cleaning the inverted material inside. Attached Figure Description

[0032] Example 1

[0033] Combination Figures 1 to 6An anti-inverting structure for a gravel concrete retarder mixing device includes a mixing tank 3, a discharge port 31 fixedly connected to the bottom right side of the mixing tank 3, a support leg 32 fixedly connected to the bottom outer ring of the mixing tank 3, a top cover 4 provided on the top of the mixing tank 3, a feed port 41 fixedly connected to the left side of the top of the top cover 4, a lifting mechanism 1 provided on the outer ring of the mixing tank 3, and a mixing mechanism 2 provided at the bottom of the top cover 4.

[0034] The lifting mechanism 1 includes a splicing component 11, a driving component 12, and a transmission component 13. The splicing component 11 is located on the outer ring of the mixing tank 3, the driving component 12 is located on the front and rear sides of the mixing tank 3, and the transmission component 13 is located on the outer ring of the mixing tank 3.

[0035] The splicing assembly 11 includes a sealing ring 1101, which is fixedly connected to the bottom of the top cover 4 and snapped into the top of the mixing tank 3. An auxiliary ring 1102 is provided on the outer ring of the sealing ring 1101, and is fixedly connected to the bottom of the outer ring of the top cover 4. An auxiliary ring 1103 is provided below the auxiliary ring 1102 and is fixedly connected to the top of the outer ring of the mixing tank 3. The drive assembly 12 includes a stepper motor 1201, which is fixedly connected to the front and rear sides of the mixing tank 3. A drive shaft 1202 is fixedly connected to the top of the stepper motor 1201, and a drive gear 1203 is fixedly connected to the outer ring of the drive shaft 1202. A sleeve 12 is rotatably connected to the top of the outer ring of the drive shaft 1202. 04. The sleeve plate 1204 is fixedly connected to the front and rear sides of the auxiliary ring 1103.

The bottom of the threaded rod 1303 is fixedly connected with a limit piece 1304.

[0036] Furthermore, the operator only needs to start the stepper motors 1201 on both the front and rear sides to drive the multiple threaded drums 1301 to rotate synchronously. By controlling the multiple threaded rods 1303 to move up and down synchronously, the operator can control the up and down movement of the top cover 4. This makes it easy for the operator to adjust the opening and closing state of the top cover 4. At the same time, the easy opening and closing of the mixing tank 3 and the top cover 4 also allows the overall structure of the mixing mechanism 2 to be moved directly above the mixing tank 3, so that the operator can directly flush and clean the inner wall and internal structure of the mixing tank 3 and the top cover 4. The operation is simple and convenient for the operator to use.

[0037] Example 2

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 Furthermore, based on Embodiment 1, the mixing mechanism 2 includes a mixing component 21, a top wall cleaning component 22, a wall scraping component 23, and a bottom material removal component 24. The mixing component 21 is disposed inside the top cover 4, the top wall cleaning component 22 is disposed at the top of the outer ring of the mixing component 21, the wall scraping component 23 is disposed at the outer ring of the mixing component 21, and the bottom material removal component 24 is disposed at the bottom of the outer ring of the mixing component 21.

[0039] The mixing assembly 21 includes a drive motor 2101, which is fixedly connected to the top of the top cover 4. A rotating shaft 2102 is fixedly connected to the bottom of the drive motor 2101. A stirring rod 2103 is fixedly connected to the outer ring of the rotating shaft 2102. A retaining shaft 2104 is rotatably connected to the bottom of the rotating shaft 2102. The retaining shaft 2104 is fixedly connected to the bottom of the mixing tank 3. The top wall cleaning assembly 22 includes an L-shaped top wall scraper 2201, which is slidably connected to the top of the inner ring of the top cover 4. A connecting rod 2202 is fixedly connected to the bottom of the L-shaped top wall scraper 2201. A fixing arm 2203 is fixedly connected to the inner side of the connecting rod 2202. The wall scraping assembly 23 includes a fixed ring 2301, which is fixedly connected to the outer ring of the rotating shaft 2102 and is positioned between the upper and lower stirring rods 2103. A protruding rod 2302 is fixedly connected to the outer ring of the fixed ring 2301, and an angled scraper 2303 is fixedly connected to the outer side of the protruding rod 2302. The angled scraper 2303 is slidably connected to the inner ring of the mixing tank 3. The bottom material removal assembly 24 includes a protruding ring 2401, which is fixedly connected to the bottom of the outer ring of the rotating shaft 2102. An arc-shaped scraper 2402 is fixedly connected to the outer ring of the protruding ring 2401 and is slidably connected to the bottom of the mixing tank 3.

[0040] Furthermore: After the drive motor 2101 starts and mixes the concrete material in the mixing tank 3 through the stirring rod 2103, the material remaining in the mixing tank 3 and the inner wall of the top cover 4 after the concrete is discharged is cleaned from top to bottom by the rotation of the L-shaped top wall scraper 2201 and the angled scraper 2303, so that the residual material falls to the bottom of the mixing tank 3. Finally, the material is pushed into the discharge port 31 by the rotation of the arc-shaped scraper 2402, thus completing the self-cleaning of the inverted material in the mixing tank 3, reducing the workload of the staff when cleaning the inverted material inside.

[0041] In actual operation, when this device is in use, the drive motor 2101 starts and drives the stirring rod 2103 to rotate via the rotating shaft 2102. The rotating stirring rod 2103 stirs and mixes the concrete raw materials in the mixing tank 3. After the concrete raw materials are prepared, they are discharged through the discharge port 31. Afterwards, some raw materials will remain and adhere to the inner wall of the mixing tank 3 and the top cover 4. At this time, do not turn off the drive motor 2101. Continue to start the drive motor 2101, and the rotating shaft 2102 will continue to rotate while driving the L-shaped top wall scraper. 2201, the angled scraper 2303, and the arc-shaped scraper 2402 rotate. The L-shaped top wall scraper 2201 is fixed to the rotating shaft 2102 via the connecting rod 2202 and the fixed arm 2203 and rotates with the rotating shaft 2102. The angled scraper 2303 is fixed to the outer ring of the rotating shaft 2102 via the protruding rod 2302 and the fixing ring 2301 and rotates with the rotating shaft 2102. The arc-shaped scraper 2402 is directly fixed to the bottom of the outer ring of the rotating shaft 2102 via the protruding ring 2401 and rotates with the rotating shaft 2102.

[0042] The three work together to scrape and clean the raw materials adhering to the inner wall of the top cover 4 and the inner wall of the mixing tank 3 from top to bottom. The residual raw materials fall to the bottom of the mixing tank 3. Finally, the raw materials are driven into the discharge port 31 by the rotation of the arc-shaped scraper 2402 and discharged. At this time, the self-cleaning of the upside-down raw materials in the mixing tank 3 is completed.

[0043] Then, the stepper motors 1201 on both the front and rear sides are started. The start of the stepper motors 1201 drives the drive gears 1203 to rotate through the drive shaft 1202. The drive gears 1203 on both the front and rear sides rotate synchronously and in the same direction, driving the gear ring 1205 to rotate. The rotation of the sleeve plate 1204 drives the multiple threaded drums 1301 to rotate synchronously through the gear ring 1302. The rotation of the threaded drums 1301 drives the threaded rod 1303 to move upward. The upward movement of the threaded rod 1303 drives the top cover 4 to move upward through the auxiliary ring 1102. The upward movement of the top cover 4 drives the entire structure of the mixing mechanism 2 to move upward and disengage from the mixing tank 3. After that, the staff can directly spray and clean the internal structure of the mixing tank 3 with a water gun.
