Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a cement-stabilized crushed stone base course batching equipment. Background Technology

[0002] In the field of road construction engineering, cement-stabilized crushed stone base course has become a commonly used material for road base structure due to its excellent mechanical properties, high stability and good fatigue resistance. It is widely used in construction projects of highways and urban roads at all levels. Its quality directly affects the overall strength, durability and service life of the road.

[0003] Currently, although the existing cement-stabilized crushed stone base course batching equipment on the market can meet production needs to a certain extent, there are still problems that need to be solved.

[0004] The material feeding method of existing equipment is relatively simple. Materials are usually put in through only one inlet. This method makes it difficult for materials to be evenly distributed after entering the equipment, and it is difficult to quickly and evenly distribute them throughout the batching space. This not only increases the time required for batching and mixing and reduces production efficiency, but also easily leads to poor consistency of the quality of the mixed materials, which cannot give full play to the performance advantages of cement-stabilized crushed stone. In large-scale road construction projects, this inefficient batching method will seriously affect the project progress and increase construction costs.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[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] Please see Figures 1-4 This utility model provides a technical solution: a cement-stabilized crushed stone base course batching device, comprising...

[0027] The mixing box 2 has a mixing chamber inside, a feed inlet at the top that communicates with the mixing chamber, and a discharge pipe 3 at the bottom that communicates with the mixing chamber.

[0028] A mixing cylinder 7 is rotatably installed inside the feed inlet. A feed hopper 8 is connected to the top of the mixing cylinder 7. A stirring shaft 9 is rotatably connected to the bottom wall of the mixing cylinder 7. A stirring paddle 10 is installed on the outer wall of the mixing shaft 9 extending into the inner part of the batching box 2. Multiple dispersion tubes 17 extending into the inner part of the batching box 2 are installed circumferentially on the bottom wall of the mixing cylinder 7.

[0029] Specifically, the batching bin 2 has a batching chamber inside. The material enters the mixing cylinder 7 through the top inlet and the feed hopper 8. The bottom of the mixing cylinder 7 is rotatably connected to the stirring shaft 9, which extends into the interior of the batching bin 2. The outer wall of the stirring shaft 9 is equipped with a stirring paddle 10. When the stirring shaft 9 rotates, the stirring paddle 10 stirs the material in the batching bin 2. At the same time, multiple dispersion pipes 17 extending into the interior of the batching bin 2 are installed circumferentially on the bottom wall of the mixing cylinder 7. The material is dispersed into the batching bin 2 from the dispersion pipes 17. This design effectively solves the problem of uneven material dispersion in existing equipment, making the material more evenly distributed when it enters the batching bin 2, reducing the subsequent mixing time, improving production efficiency and material mixing quality, helping to give full play to the performance advantages of cement-stabilized crushed stone, and reducing the cost of large-scale road construction projects.

[0030] See Figure 1 A drive motor 11 is installed on the outer wall of the mixing box 2. The drive end of the drive motor 11 is connected to a drive shaft 12. The top end of the drive shaft 12 and the top end of the stirring shaft 9 are both connected to a first synchronous pulley 13. A first synchronous belt 14 is connected between the two first synchronous pulleys 13.

[0031] Specifically, a drive motor 11 is installed on the outer wall of the batching box 2, and its drive end is connected to a drive shaft 12. The top of the drive shaft 12 and the top of the stirring shaft 9 are both connected to the first synchronous pulley 13, and are connected by a first synchronous belt 14. After the drive motor 11 is started, the power is transmitted to the stirring shaft 9 through the drive shaft 12, the first synchronous pulley 13 and the first synchronous belt 14, which drives the stirring paddle 10 to rotate. This structure uses synchronous pulleys and synchronous belts for transmission, which is not only simple in structure and smooth in transmission, but also accurately transmits power and ensures stable rotation of the stirring shaft 9. It effectively solves the problem of uneven material mixing caused by unstable stirring in existing equipment and improves the batching quality.

[0032] See Figure 1 A second synchronous pulley 15 is installed on the outer wall of the drive shaft 12 and the outer wall of the mixing cylinder 7, and a second synchronous belt 16 is connected between the two second synchronous pulleys 15.

[0033] Specifically, the drive shaft 12 and the outer wall of the mixing cylinder 7 are respectively equipped with second synchronous pulleys 15 and are connected by a second synchronous belt 16. When the drive motor 11 is running, the drive shaft 12 drives the second synchronous pulleys 15 to rotate, which in turn drives the mixing cylinder 7 to rotate through the second synchronous belt 16. This allows the mixing cylinder 7 to rotate, which, together with the dispersion tube 17, further expands the material dispersion effect, allowing the material to enter the batching box 2 more evenly, improving the material mixing uniformity, improving the poor material dispersion of existing equipment, and improving production efficiency and product quality.

[0034] See Figure 1 and Figure 4A gear ring 18 is rotatably mounted on the top surface of the feed hopper 8. A transmission gear 19 that meshes with the gear ring 18 is mounted on the drive shaft 12. A support 21 is mounted on the inner wall of the feed hopper 8. A dispensing cylinder 22 is mounted on the support 21. The feed hopper 8 is located on the top wall of the dispensing cylinder 22. A discharge pipe is located on the bottom wall of the dispensing cylinder 22, and the discharge pipe corresponds to the feed hopper 8.

[0035] Specifically, a transmission gear 19 is installed on the drive shaft 12, which meshes with a gear ring 18 rotatably mounted on the top surface of the feed hopper 8. The rotation of the drive shaft 12 drives the gear ring 18 to rotate. When the gear ring 18 rotates, it drives the feeding cylinder 22, which is installed inside the feed hopper 8 through the support 21, to rotate. The material enters the feed hopper 8 from the top wall of the feeding cylinder 22 and falls into the feed hopper 8 from the bottom wall discharge pipe. Through the meshing transmission of the gear ring 18 and the transmission gear 19, the rotation of the feeding cylinder 22 is realized, changing the position of the material entering the feed hopper 8, further promoting the dispersion of the material and preventing the material from concentrating in one place.

[0036] See Figures 1-4 A friction ring 20 is installed on the top surface of the toothed ring 18. A rotating shaft 23 is rotatably installed inside the dispensing cylinder 22. A spiral auger 24 is installed on the outer wall of the rotating shaft 23. A friction wheel 25 is connected to one end of the rotating shaft 23 that extends to the outside of the dispensing cylinder 22. The friction wheel 25 rubs against the friction ring 20.

[0037] Specifically, a friction ring 20 is installed on the top surface of the toothed ring 18. The friction wheel 25 connected to one end of the rotating shaft 23 inside the feeding cylinder 22 rubs against the friction ring 20. When the toothed ring 18 rotates, the friction ring 20 drives the friction wheel 25 to rotate, which in turn causes the rotating shaft 23 to rotate. The spiral auger 24 on the outer wall of the rotating shaft 23 rotates accordingly, conveying the material inside the feeding cylinder 22. The rotation of the spiral auger 24 is achieved by friction transmission, which can control the speed at which the material enters the feed hopper 8, ensuring that the material enters evenly and continuously, improving the accuracy of the batching and the uniformity of the mixing, and solving the problems of unstable material feeding speed and uneven mixing in existing equipment.

[0038] See Figure 1 Multiple batching cylinders 22 are provided, and the multiple batching cylinders 22 are arranged around the outer circumference of the top surface of the feed hopper 8.

[0039] Specifically, multiple batching cylinders 22 are arranged around the outer circumference of the top surface of the feed hopper 8. Different materials can be placed in different batching cylinders 22. During rotation, different materials fall into the feed hopper 8 from different positions. This design allows multiple materials to enter the feed hopper 8 more evenly, increases the uniformity of material mixing, and improves the batching quality of cement-stabilized crushed stone base course.

[0040] See Figure 1 and Figure 3The bottom of the discharge pipe 3 is connected to the conveying pipe 4. One end of the conveying pipe 4 is open and the other end is sealed. The inside of the conveying pipe 4 is equipped with a discharge auger 6. The side wall of the sealed end of the conveying pipe 4 is equipped with a conveying motor 5 for driving the discharge auger 6 to rotate.

[0041] Specifically, the conveyor motor 5 starts, driving the discharge auger 6 inside the conveying pipe 4 to rotate. The discharge pipe 3 at the bottom of the batching box 2 is connected to the conveying pipe 4. The mixed material enters the conveying pipe 4 from the discharge pipe 3 and is discharged from the open end of the conveying pipe 4 under the action of the discharge auger 6. This structure realizes efficient material conveying, ensures the continuity of material output from the batching equipment, and improves production efficiency.

[0042] See Figure 1 It also includes a bracket 1, with the ingredient box 2 fixedly installed on the bracket 1, and the bracket 1 supported on the ground.

[0043] Specifically, bracket 1 supports batching box 2 and fixes it to the ground, providing a stable support structure for the batching equipment; ensuring the overall stability of the batching equipment, ensuring that the equipment will not shake or shift during operation, and guaranteeing the normal operation of the equipment and the quality of material mixing.

[0044] Working principle: After the equipment is started, the drive motor 11 works and outputs power to the drive shaft 12. The drive shaft 12 drives the stirring shaft 9 to rotate through the first synchronous pulley 13 and the first synchronous belt 14, so that the stirring paddle 10 stirs the materials in the batching box 2. At the same time, the drive shaft 12 drives the mixing cylinder 7 to rotate through the second synchronous pulley 15 and the second synchronous belt 16.

[0045] Material enters from multiple feeding cylinders 22 arranged circumferentially around the top surface of the feed hopper 8. The toothed ring 18 rotates under the drive of the transmission gear 19, causing the feeding cylinders 22 to rotate accordingly, changing the position of the material entering the feed hopper 8. When the toothed ring 18 rotates, the friction ring 20 on its top surface drives the friction wheel 25 at one end of the rotating shaft 23 inside the feeding cylinder 22 to rotate, thereby causing the spiral auger 24 to rotate, controlling the speed at which the material enters the feed hopper 8. The material enters the mixing cylinder 7 through the feed hopper 8, and then is dispersed into the feeding box 2 through the dispersion pipe 17 on the bottom wall of the mixing cylinder 7.

[0046] The materials that have been mixed in the batching box 2 enter the conveying pipe 4 through the discharge pipe 3 at the bottom. The conveying motor 5 drives the discharge auger 6 to rotate, and discharges the mixed materials from the open end of the conveying pipe 4. The entire equipment is supported by the bracket 1 and fixed to the ground to ensure stable operation.

[0047] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
