Description

Technical Field

[0001] This utility model relates to the technical field of crushing devices for civil engineering, and in particular to a novel rock crusher for civil engineering. Background Technology

[0002] In the field of civil engineering, rock crushers are common equipment used to break large rocks into smaller particles for subsequent processing such as roadbed paving and concrete preparation. Traditional rock crushers typically include a basic structure such as a frame, feeding chamber, crushing chamber, and discharge chamber. The feeding chamber is located at the top, the crushing chamber has a motor-driven crushing roller in the middle, and the discharge chamber is located at the bottom to discharge the crushed stone. However, this traditional design has several significant drawbacks that affect the efficiency and reliability of the equipment.

[0003] First, the feeding system is often quite simple, typically using only one or a few feeding ports, resulting in uneven distribution of the stone entering the crushing chamber. This easily leads to excessive localized load on the crushing rollers, while other areas are underutilized, thus reducing overall crushing efficiency and potentially causing overheating or accelerated wear of the equipment. When the stone varies in size, traditional feeding ports cannot effectively distinguish or guide materials of different sizes, often resulting in large stones clogging the feeding channel or small stones entering the crushing zone prematurely, causing unstable crushing quality and uneven particle size output.

[0004] Secondly, the flow guiding device may be missing or poorly designed in traditional crushers. Without an effective guide plate system, the stone is prone to deviation, accumulation, or rebound during feeding. This not only increases energy consumption but can also lead to blockage inside the feeding chamber, requiring frequent shutdowns for cleaning and affecting continuous operation. The flow of stone within the crushing chamber is also not smooth. Due to the lack of optimized flow guiding, the stone may not contact the crushing rollers evenly, resulting in incomplete crushing and even the creation of large, uncrushed residues that require secondary processing, increasing time and costs. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is: how to provide a new type of rock crusher for civil engineering that can effectively guide the concentrated falling of stone materials, prevent deviation and blockage, and ensure uniform and continuous feeding.

[0006] To achieve the above objectives, this utility model proposes a novel rock crusher for civil engineering, which includes a frame, a feeding chamber, a crushing chamber, a discharge chamber, a motor, a crushing roller, a first feeding port, a second feeding port, a first guide plate, a second guide plate, and a third guide plate. The feeding chamber, the crushing chamber, and the discharge chamber are fixedly mounted on the frame, with the feeding chamber and the discharge chamber respectively connected above and below the crushing chamber. The motor is fixedly mounted on the frame, and the output end of the motor is connected to the crushing roller. The two ends of the crushing roller are rotatably connected to the side wall of the crushing chamber. The motor drives the crushing roller to rotate in the crushing chamber. The stone enters the crushing chamber through the feeding chamber. The crushing roller driven by the motor crushes the stone in the crushing chamber. The crushed stone is discharged from the discharge chamber. The first feeding port and the second feeding port are provided inside the feeding chamber and on one side close to the crushing chamber. The first feeding port is located in the middle of the feeding chamber, and the two second feeding ports are respectively located on both sides of the first feeding port. The inner diameter of the first feeding port is larger than the inner diameter of the second feeding port. The two first guide plates are located below the first feeding port and are arranged at an angle, with the opening formed by the two first guide plates facing downwards; The two second guide plates are respectively located on the side of the two first guide plates and close to the side wall of the feeding chamber, and each second guide plate is parallel to the first guide plate on its adjacent side. The third guide plate is located below the first guide plate and the second guide plate. The two third guide plates are located on both sides of the feeding cavity, and the top of the third guide plate is connected to the side wall of the feeding cavity. The extension direction of the third guide plate is perpendicular to the extension direction of the second guide plate or the first guide plate.

[0007] Furthermore, the first guide plate and the second guide plate are arranged along the same horizontal plane.

[0008] Furthermore, the top of the second guide plate is connected to the connection between the first feeding port and the second feeding port.

[0009] Furthermore, the end of the third guide plate extends toward the center of the feeding chamber.

[0010] Compared with related technologies, the novel rock crusher for civil engineering proposed in this utility model has the following advantages: The feeding chamber is equipped with a first feeding port and a second feeding port. The first port has a larger inner diameter and is located in the middle, while the second port has a smaller inner diameter and is located on both sides. This configuration allows stones to enter in stages according to size, with larger stones passing through the first port and smaller stones through the second port. This optimizes the feeding process, improves processing efficiency, reduces equipment impact and wear caused by uneven stone size, and extends service life. The guide plate system includes a first guide plate, a second guide plate, and a third guide plate. The first guide plate is arranged obliquely and forms a downward opening to guide the stones to fall in a concentrated manner. The second guide plate is parallel to the first guide plate and connected to the feeding port to stabilize the stone flow. The third guide plate is located below, extending vertically with its end extending towards the middle, effectively preventing stone deviation or accumulation, ensuring that the stones enter the crushing chamber uniformly and continuously, avoiding blockage, reducing maintenance requirements, and improving the uniformity of crushing.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] Please see Figure 1 - Figure 3 As shown, this utility model proposes a novel rock crusher for civil engineering, which includes a frame 11, a feeding chamber 12, a crushing chamber 13, a discharge chamber 14, a motor 15, a crushing roller 16, a first feeding port 21, a second feeding port 22, a first guide plate 31, a second guide plate 32, and a third guide plate 33.

[0014] The feeding chamber 12, crushing chamber 13 and discharge chamber 14 are fixedly mounted on the frame 11. The feeding chamber 12 and discharge chamber 14 are respectively connected and located above and below the crushing chamber 13.

[0015] The motor 15 is fixedly mounted on the frame 11. The output end of the motor 15 is connected to the crushing roller 16. The two ends of the crushing roller 16 are rotatably connected to the side wall of the crushing chamber 13. The motor 15 drives the crushing roller 16 to rotate in the crushing chamber 13. The stone enters the crushing chamber 13 through the feeding chamber 12. The crushing roller 16 driven by the motor 15 crushes the stone in the crushing chamber 13. The crushed stone is discharged through the discharge chamber 14.

[0016] The feeding chamber 12 and the discharge chamber 14 are respectively connected and located above and below the crushing chamber 13. This layout optimizes the flow path of the stone and realizes a continuous processing flow from input to output, thereby improving crushing efficiency and reducing the risk of material blockage. The feeding chamber 12 is responsible for introducing uncrushed stone into the crushing area, while the discharge chamber 14 promptly discharges crushed material, ensuring smooth operation of the entire system.

[0017] The stone material enters the crushing chamber 13 through the feeding chamber 12, and the crushing roller 16 driven by the motor 15 crushes the stone material. The crushed stone material is then discharged through the discharge chamber 14.

[0018] A first feeding port 21 and a second feeding port 22 are provided inside the feeding chamber 12 and on one side near the crushing chamber 13. The first feeding port 21 is located in the middle of the feeding chamber 12, and the two second feeding ports 22 are located on both sides of the first feeding port 21. The inner diameter of the first feeding port 21 is larger than the inner diameter of the second feeding port 22.

[0019] A first feeding port 21 and a second feeding port 22 are provided inside the feeding chamber 12 and on one side near the crushing chamber 13 to optimize the introduction and distribution of stone materials, thereby improving the overall efficiency of the crusher. The first feeding port 21 is located in the middle of the feeding chamber 12 and has a large inner diameter, which facilitates the accommodation and guidance of larger stone materials into the crushing chamber 13, ensuring the smooth flow of the main material.

[0020] The two second feeding ports 22 are located on both sides of the first feeding port 21, and have a smaller inner diameter, which helps to process smaller or auxiliary stones, realize the initial classification and diversion of materials, and avoid the congestion that may be caused by a single port.

[0021] By combining large and small ports, the stone material is uniformly fed into the crushing chamber 13, reducing the risk of material accumulation and blockage during the feeding process. The large inner diameter design of the first feeding port 21 allows for efficient processing of mainstream stone material, while the small inner diameter of the second feeding port 22 supplements the introduction of lateral material. Together, they ensure that the crushing roller 16 receives a stable and reasonably distributed flow of stone material, thereby improving the crushing effect and equipment reliability.

[0022] Adaptable to different sizes of stone input, the crusher's applicability and operational flexibility are enhanced, significantly improving production efficiency and maintenance convenience in civil engineering applications.

[0023] The two first guide plates 31 are located below the first feeding port 21 and are arranged at an angle, with the opening formed by the two first guide plates 31 facing downward.

[0024] Two second guide plates 32 are respectively located on the side of the two first guide plates 31 and close to the side wall of the feeding chamber 12. Each second guide plate 32 is parallel to the first guide plate 31 on its adjacent side. The top of the second guide plate 32 is connected to the connection between the first feeding port 21 and the second feeding port 22. The first guide plate 31 and the second guide plate 32 are arranged along the same horizontal plane.

[0025] Two first guide plates 31 are located below the first feeding port 21 and are arranged at an angle. The opening formed by them faces downward, effectively guiding the stone material smoothly into the crushing chamber 13 from the feeding port. The angled structure promotes the downward flow of the material under the action of gravity, avoiding accumulation or blockage in the transition area.

[0026] This ensures that the stone is concentrated and evenly distributed in the working area of ​​the crushing roller 16, thereby improving crushing efficiency, reducing energy consumption, and enhancing the stability and reliability of the equipment. In the overall rock crusher solution, the first guide plate 31 plays a key role in guiding the stone, optimizing the material flow path, preventing stone deviation or splashing, and ensuring a continuous and efficient processing process.

[0027] Two second guide plates 32 are respectively located beside the two first guide plates 31 and close to the side wall of the feeding chamber 12. Each second guide plate 32 is parallel to its adjacent first guide plate 31, and the top of the second guide plate 32 is connected to the connection between the first feeding port 21 and the second feeding port 22. This layout is designed to supplement the guiding function of the first guide plates 31, provide additional lateral support, and integrate the material flow from different ports, ensuring a smooth transition of the stone and avoiding uneven flow caused by differences in port size. The first guide plates 31 and the second guide plates 32 are arranged along the same horizontal plane, realizing the coordinated operation of the guide plate system, jointly maintaining the stable downward movement of the stone, reducing the impact and vibration in the crushing chamber 13, thereby improving the overall crushing quality and equipment durability.

[0028] The third guide plate 33 is located below the first guide plate 31 and the second guide plate 32. The two third guide plates 33 are located on both sides of the feeding cavity 12, and the top of the third guide plate 33 is connected to the side wall of the feeding cavity 12. The extension direction of the third guide plate 33 is perpendicular to the extension direction of the second guide plate 32 or the first guide plate 31.

[0029] The extension direction of the third guide plate 33 is perpendicular to the extension direction of the second guide plate 32 or the first guide plate 31. This vertical arrangement provides a cross-guiding function, which helps to gather the stone from the side of the feeding chamber 12 towards the central area, ensuring that the material is evenly distributed and smoothly enters the crushing chamber 13. The end extends towards the center of the feeding chamber 12, thereby enhancing the concentrated guidance of the stone and reducing energy loss and potential blockage risk during the flow process.

[0030] By guiding the lateral stones to the center, the third guide plate 33 ensures that the crushing roller 16 receives a uniform and continuous flow of stones, avoiding uneven loading or local overload, thereby improving crushing efficiency and equipment reliability.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
