Description

Technical Field

[0002] With the rapid development of the construction industry and the deepening of the concept of sustainable development, recycled concrete, as a green building material made by crushing and grading waste concrete and then remixing it with cement, aggregates, etc., has attracted much attention because it can effectively reduce construction waste emissions and alleviate the pressure on natural aggregate mining. However, there are many problems with the recycled concrete batching equipment currently on the market in practical applications.

[0003] Currently, most equipment has independent crushing and mixing functions, requiring multiple devices and complex intermediate transfer links to complete the process from raw material crushing to mixing. This not only occupies a large area and has high equipment investment costs, but also easily causes material loss during the transfer process, affecting production efficiency and batching accuracy. Existing batching control methods are relatively crude, and it is difficult to accurately control the amount of water and materials added. Relying solely on manual experience or simple mechanical valve adjustments leads to large errors in the proportion of recycled concrete, making it impossible to consistently meet the stringent quality requirements of recycled concrete in engineering construction. The performance of the finished product fluctuates significantly, limiting the large-scale promotion and application of recycled concrete. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a batching device for recycled concrete, including a support frame 1, a lower cylinder 2 fixedly connected to the top of the support frame 1, a servo motor A7 disposed on the lower surface of the lower cylinder 2, a drive gear 9 fixedly connected to the output end of the servo motor A7, a driven gear 10 meshing with the surface of the drive gear 9, a crushing rod 11 fixedly connected to the surface of the driven gear 10, a feeding pipe 6 fixedly connected to the outer wall of the lower cylinder 2, a mixing cylinder 13 fixedly connected to the lower end of the feeding pipe 6, and a servo motor 13 installed at one end of the mixing cylinder 13. Machine B14, the output end of which is fixedly connected to a spiral blade frame 15, drives the drive gear 9 through the servo motor A, the drive gear 9 meshes with the driven gear 10, causing the crushing rod 11 fixed on the driven gear 10 to rotate, thereby crushing the recycled concrete raw materials in the lower cylinder 2, crushing larger particles into smaller particles, which is beneficial for subsequent stirring and mixing, and improving the uniformity and quality of the batching. When the crushed material enters the mixing cylinder 13 through the feed pipe 6, the servo motor B at one end of the mixing cylinder 13 drives the spiral blade frame 15 to rotate, so as to fully stir and mix the material.

[0026] Reference Figure 1 , Figure 3 and Figure 4As shown in this embodiment: a partition 5 is fixedly connected to the inner wall of the lower cylinder 2. The partition 5 has a "Y" shaped cross-section. A mounting bracket 8 is fixedly connected to the surface of the servo motor A7. The upper surface of the mounting bracket 8 is fixedly connected to the lower surface of the lower cylinder 2. The crushing rod 11 is located inside the lower cylinder 2, and the number of crushing rods 11 is set to three sets. The surfaces of the three sets of crushing rods 11 are rotatably connected to a fixing bracket 12. The fixing bracket 12 is fixedly connected to the lower surface of the lower cylinder 2. The lower cylinder 2 is divided into three uniformly sized spaces by the "Y" shaped partition 5, so that different materials can be crushed by the three sets of crushing rods 11, thereby improving the practicality of the device.

[0027] Reference Figure 1 and Figure 2 As shown, specifically, a water storage tank 17 is fixedly connected to the upper surface of the support frame 1, and a water guide pipe 18 is fixedly connected to one side of the water storage tank 17. The lower end of the water guide pipe 18 is connected to the interior of the mixing drum 13. A regulating valve A19 is provided on the surface of the water guide pipe 18, and a regulating valve B20 is provided on the surface of the discharge pipe 6. The regulating valve B on the discharge pipe 6 can precisely control the amount of material entering the mixing drum 13 from the lower drum body 2, and the regulating valve A on the water guide pipe 18 can accurately control the amount of water entering the mixing drum 13. Thus, the proportion of various ingredients can be controlled according to the requirements of recycled concrete to ensure the product quality. To ensure consistent quality, an upper cylinder cover 3 is bolted to the upper surface of the lower cylinder 2. A sealing cover 4 is hinged to the top of the upper cylinder cover 3, facilitating the addition of raw materials. A capacity window 21 is provided on the surface of the water storage tank 17. A collection cylinder 16 is provided below the discharge port of the mixing cylinder 13. The capacity window 21 on the surface of the water storage tank 17 allows operators to observe the water level and replenish water in a timely manner. The collection cylinder 16 below the discharge port of the mixing cylinder 13 facilitates the collection of the mixed recycled concrete, making it easier for subsequent transportation and use, thus improving production efficiency.

[0028] Working principle: First, various raw materials are placed into the spaces separated by partition 5. Then, servo motor A7 is turned on, and its output drives drive gear 9 to rotate. When drive gear 9 rotates, it simultaneously drives three sets of driven gears 10 to move synchronously, causing the crushing rod 11 on the driven gears 10 to rotate. This crushes the recycled concrete raw materials in the lower cylinder 2, breaking larger particles into smaller ones, which is beneficial for subsequent mixing and blending, improving the uniformity and quality of the batch. During the raw material crushing process, the operator can precisely control the water flow in the water storage tank 17 by adjusting the regulating valve A on the water pipe 18 according to the preset recycled concrete formula. The flow rate to the mixing drum 13 is precisely controlled by adjusting the regulating valve B on the feed pipe 6. This ensures that the crushed material in the lower drum 2 enters the mixing drum 13 in a set ratio. Once the material and water have entered the mixing drum 13 in the set ratio, the servo motor B is started. The output of the servo motor B drives the connected spiral blade frame 15 to rotate inside the mixing drum 13. Through the stirring action of the spiral blade frame 15, the material and water are fully tumbled and stirred inside the mixing drum 13, achieving uniform mixing. Finally, the fully mixed recycled concrete is discharged through the outlet of the mixing drum 13 into the collection drum 16 below, thus completing the entire batching process of recycled concrete.
