Description

Technical Field

[0001] This utility model relates to the technical field of concrete mixing equipment, and in particular to a high-efficiency concrete mixing equipment for water conservancy projects. Background Technology

[0002] Water conservancy projects often use dams to dredge river channels. When constructing dams, concrete is required, and mixing equipment is needed to mix the concrete evenly during the dam construction process.

[0003] For example, there is a concrete mixing equipment for water conservancy engineering construction, with publication number CN218748549U. The mixing mechanism includes a mixing column fixedly connected to the output end of a drive motor. Several sets of first connecting rods are welded to the outer surface of the mixing column, and a set of scrapers are welded to the ends of the three sets of first connecting rods in the vertical direction away from the mixing column. In use, the mixing column drives the scrapers and push blocks to rotate through the first and second connecting rods respectively. When the scrapers rotate, they scrape the concrete on the inner surface of the mixing tank, allowing the concrete to be incorporated into the mixing tank and thus fully mixed inside.

[0004] However, during use, although the scraper can remove the concrete from the inner wall of the mixing tank, some concrete will stick to the scraper. Over time, the accumulation of this sticky concrete will gradually increase the weight of the scraper, thereby increasing the load on the drive motor. This may not only affect the normal operation of the equipment, but also shorten its service life. Utility Model Content

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figure 1-5 As shown, a high-efficiency concrete mixing equipment for water conservancy projects includes a mixing drum 1 and a support frame 2. A square rod 11 located at the central axis of the mixing drum 1 is rotatably connected to the top of the support frame 2. A square sleeve 12 is fitted over the square rod 11. Mixing rods 13 are fixedly connected to both sides of the square sleeve 12. Scrapers 21 for cleaning the inner wall of the mixing drum 1 are fixedly connected to both ends of the mixing rods 13. A winding reel 10 is rotatably connected to the top of the support frame 2. A steel wire rope 9 is wound on the winding reel 10. A lifting ring 3 rotatably connected to the other end of the steel wire rope 9 is fixedly connected to the lifting ring 13. The lifting ring 3 is fitted and coaxially arranged with the square rod 11. The lifting ring 3 is slidably engaged with the support frame 2. Guide grooves 5 are opened on both sides of the support frame 2. Insert rods 4 that slidably engage with the guide grooves 5 are fixedly connected to both sides of the lifting ring 3.

[0027] In this technical solution, the square rod 11 and the square sleeve 12 are fitted together. When the square rod 11 rotates, it drives the square sleeve 12 to rotate synchronously, thereby causing the mixing rods 13 on both sides of the square sleeve 12 to rotate as well, thus realizing the mixing operation of concrete in the mixing drum 1. The scrapers 21 at both ends of the mixing rods 13 can scrape off the concrete adhering to the inner wall of the mixing drum 1 during the mixing process, reducing concrete waste and ensuring the cleanliness of the inner wall of the mixing drum 1.

[0028] Furthermore, when the winding reel 10 rotates, the lifting ring 3 can be driven to move up and down along the square rod 11 via the wire rope 9. Since the lifting ring 3 is rotatably connected to the stirring rod 13, the up and down movement of the lifting ring 3 will drive the stirring rod 13 and the square sleeve 12 to move up and down along the square rod 11, thereby changing the height position of the stirring rod 13 and the scraper 21, so as to remove the scraper 21 from the inside of the mixing tank 1, making it convenient for the staff to clean.

[0029] In addition, the guide grooves 5 on both sides of the support frame 2 and the insert rods 4 on both sides of the lifting ring 3 slide together to provide guidance for the up and down movement of the lifting ring 3, ensuring the stability of the lifting ring 3 during movement, and thus ensuring the stability of the stirring rod 13 and the scraper 21 during up and down movement and rotation.

[0030] like Figure 3 As shown, a motor 8 is fixedly installed on the top surface of the support frame 2. The main shaft of the motor 8 extends outward through the support frame 2 and is fixed to the square rod 11. A wedge block 15 for supporting the square sleeve 12 is fixedly connected to the bottom end of the square rod 11.

[0031] In this technical solution, when the motor 8 starts, it can directly drive the square rod 11 to rotate around its own axis. Since the square rod 11 and the square sleeve 12 are fitted together, the rotation of the square rod 11 will drive the square sleeve 12 to rotate synchronously, and then drive the stirring rod 13 and the scraper 21 to rotate through the square sleeve 12, realizing the power transmission for stirring and scraping operations. In addition, the wedge block 15 at the bottom of the square rod 11 plays the role of supporting the square sleeve 12. When the square sleeve 12 moves down along the square rod 11 to the lowest position, the wedge block 15 can support it and prevent the square sleeve 12 from falling off the bottom of the square rod 11.

[0032] like Figure 2 and Figure 3 As shown, there are two reels 10 and two wire ropes 9, which are symmetrically distributed around the square rod 11. The support frame 2 is fixedly connected to the opposite side of the support frame. The other end of the support frame 6 is rotatably connected to the auxiliary wheel 14. The wire rope 9 passes around the auxiliary wheel 14 and is fixed to the lifting ring 3. Two meshing gears 7 are rotatably connected to one side of the support frame 2. The middle of one side of the two gears 7 extends outward and passes through the support frame 2 and is fixed to the two reels 10 respectively. A motor 8 is also fixedly installed on one side of the support frame 2. The main shaft of the motor 8 located on one side of the support frame 2 is fixed to the central shaft of one of the reels 10.

[0033] In this technical solution, two reels 10 and wire ropes 9 are symmetrically distributed around the square rod 11, which can apply a balanced tension to the lifting ring 3 from both sides, ensuring that the lifting ring 3 is subjected to uniform force during its up and down movement. Furthermore, the auxiliary wheel 14 on the mounting plate 6 inside the support frame 2 guides and supports the wire rope 9, changes the direction of force on the wire rope 9, reduces friction between the wire rope 9 and other components, reduces wear on the wire rope 9, and makes the direction of the tension of the wire rope 9 on the lifting ring 3 more reasonable, thereby improving the smoothness of the movement of the lifting ring 3.

[0034] Two meshing gears 7 are fixed to two winding reels 10 respectively. When the motor 8 on one side of the support frame 2 starts and drives one of the winding reels 10 to rotate, the winding reel 10 will drive the gear 7 connected to it to rotate. Through the meshing transmission of the two gears 7, the other gear 7 will drive the other winding reel 10 to rotate synchronously in the opposite direction, so as to realize the synchronous winding and unwinding of the wire rope 9 of the two winding reels 10.

[0035] like Figure 5 As shown, hydraulic rods 19 are fixedly connected to both sides of the support frame 2. The telescopic ends of the hydraulic rods 19 are fixedly connected to positioning slot plates 20 for limiting the movement of the insertion rod 4.

[0036] In this technical solution, the hydraulic rods 19 on both sides of the support frame 2 can move the positioning slot plate 20 through telescopic movement; when the mixing equipment is in the mixing operation state, the hydraulic rods 19 extend and push the positioning slot plate 20 to move to the bottom of the insertion rod 4 or a specific position. The positioning slot plate 20 can limit the insertion rod 4 and prevent the lifting ring 3 from unnecessary downward movement under the influence of factors such as vibration generated by the rotation of the mixing rod 13.

[0037] like Figure 3 and Figure 4 As shown, a sealing plug 16 is provided at the bottom of the mixing tank 1 and penetrates through the support frame 2. A limiting plate 17 is fixedly connected to the bottom of the sealing plug 16, and limiting grooves 18 for placing the limiting plate 17 are provided on both sides of the bottom of the support frame 2.

[0038] In this technical solution, the sealing plug 16 at the bottom of the mixing tank 1 is connected to the support frame 2 through, which can seal the discharge port at the bottom of the mixing tank 1 and prevent concrete from leaking from the bottom during the mixing process; when it is necessary to discharge the mixed concrete, the sealing plug 16 can be removed from the support frame 2, so that the concrete can flow out through the discharge port at the bottom.

[0039] The limiting plate 17 at the bottom of the sealing plug 16 works in conjunction with the limiting grooves 18 on both sides of the bottom of the support frame 2. When the sealing plug 16 is installed on the support frame 2, the limiting plate 17 is placed in the limiting groove 18, which can limit and fix the sealing plug 16, preventing the sealing plug 16 from shifting or falling off due to equipment vibration or the impact of concrete during concrete mixing, thus ensuring the sealing effect of the sealing plug 16.

[0040] The method of using this utility model is as follows: When cleaning the scraper 21, first start the motor 8 on one side of the support frame 2 to drive the connected winding reel 10 to rotate. Through the transmission of two meshing gears 7, the other winding reel 10 rotates synchronously in the opposite direction. The two winding reels 10 release the wire rope 9, which passes around the auxiliary wheel 14 and drives the lifting ring 3 to move upward along the square rod 11. The insert rods 4 on both sides of the lifting ring 3 slide along the guide groove 5 of the support frame 2, thereby driving the mixing rod 13 and the square sleeve 12 to move upward along the square rod 11, and removing the scraper 21 from the inside of the mixing tank 1. After the scraper 21 is completely removed from the mixing tank 1, the workers can clean the concrete adhering to the scraper 21.

[0041] The wiring diagrams of the motor 8 and hydraulic rod 19 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the motor 8 and hydraulic rod 19 will not be explained in detail.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
