[0002] Building material crushing equipment used in rural construction is mainly a mechanical device used to crush and pulverize large pieces of building materials or waste. This equipment can crush building materials such as bricks, stones, and concrete blocks into smaller particles for reuse or as raw materials for other building materials. Common types of building material crushing equipment include: crushers, hammer mills, impact crushers, and cone crushers. Crushing equipment in rural construction is primarily used to reduce the environmental pollution caused by construction waste, achieve waste reduction and resource recovery, reduce construction costs, and improve resource utilization rates through waste recycling.

[0003] Existing building material crushing equipment may generate dust during the crushing process. Without an effective collection and filtration system, this will pollute the air. Some crushing equipment has limited material processing capacity, especially when the material is large in size or has high hardness. The processing efficiency of the equipment will decrease. If it cannot effectively process large or hard materials, these materials will get stuck inside the crusher shell and the crushing rollers. The structural design of existing crushing equipment makes it impossible to quickly and easily process the materials stuck in the shell, and the processing is not convenient.

[0004] Therefore, it is necessary to invent a building material crushing device for rural construction to solve the above problems. Utility Model Content

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-5The building material crushing equipment for rural construction shown includes a frame 1, which is composed of an upper shell 11, a lower shell 12, and a flow guide shroud 13. The upper shell 11 has a feed port 8 at its top, which serves as the entry point for building materials into the equipment and plays a crucial role in conjunction with the flow guide shroud 13. The upper shell 11 and lower shell 12 are joined together. This joint structure allows operators to assemble the upper shell 11 and lower shell 12 separately before fastening them together with bolts. This simple and easy operation reduces assembly difficulty and installation costs, facilitating on-site installation in rural construction sites. Furthermore, during subsequent use of the equipment, if large-scale overhaul or replacement of internal components is required, the shell can be easily disassembled, allowing personnel to enter the equipment to operate on key components such as the crushing roller 5. This improves the overall maintainability of the equipment, extends its service life, and adapts to the relatively limited technical and human maintenance conditions in rural construction. The guide shroud 13 is located at the top of the upper shell 11. Specifically, the cross-sectional shape of the guide shroud 13 is set as Z-shaped, and its inner wall is set as a slope. The guide shroud 13 has an approximate Z-shaped structure. By increasing the length and tilt angle of the middle section of the guide shroud 13, it is possible to facilitate the material to fall from the guide shroud 13 and reduce the splashing of dust during the material falling process. The dust can be concentrated in the middle section of the guide shroud 13 to reduce the dust from being stirred up. Opening and closing mechanisms 2 are provided on both sides of the upper part of the frame 1.

[0030] Opening and closing mechanism 2 includes:

[0031] Two baffles 21 are respectively disposed on both sides of the upper housing 11 and the lower housing 12 assembly, and the two baffles 21 close and seal the openings formed by the combination of the upper housing 11 and the lower housing 12.

[0032] Two cylinders 22 are respectively located at both ends of the upper housing 11 and near the top. The two cylinders 22 face each other but are asymmetrically arranged. This asymmetrical design allows more component structures to be installed in the limited area on both sides of the upper end of the frame 1. Furthermore, when the two cylinders 22 move, it prevents them from colliding when they are on the same side.

[0033] Dust hoods 4 are provided on both sides of the lower end of the frame 1, and brackets are fixedly installed on both sides of the lower end of the lower housing 12. The two dust hoods 4 are set in the brackets on both sides of the lower housing 12. The two ends of the dust hoods 4 are fixedly connected to the inside of the brackets through the mounting parts, thereby ensuring the stability of the dust hoods 4 during the operation of the equipment. This installation method allows the dust hoods 4 to be accurately aligned with the discharge port 9.

[0034] Furthermore, in the above technical solution, the top of the upper shell 11 is provided with a feeding port 8, and the bottom of the guide shroud 13 is fixedly connected to the feeding port 8 by bolts, which can guide and gather the input material, so that the material can enter the crushing area inside the equipment accurately and smoothly in a predetermined direction, and avoid the material from scattering everywhere when feeding. The bottom of the lower shell 12 is provided with a discharge port 9, and several dustproof strips 3 are fixedly installed on the outside of the bottom end of the discharge port 9.

[0035] Furthermore, in the above technical solution, the dust hood 4 is installed at an angle inside the bracket of the lower housing 12, and the opening of the dust hood 4 corresponds to the discharge port 9 of the lower housing 12, so that during the material discharge process, the dust hood 4 can effectively capture the dust overflowing from the dustproof strip 3, play its dust suction role, and cooperate with the dust collection system of the entire equipment to achieve efficient control of the dust generated during the crushing process and reduce the pollution of the surrounding environment by dust. The outer connection port of the dust hood 4 is connected to a dust suction device through a conduit.

[0036] Furthermore, in the above technical solution, the opposite ends of the external protrusions of the upper housing 11 and the lower housing 12 are fixedly connected by multiple bolts. The two sides of the upper housing 11 and the lower housing 12 are hollow opening structures. Two baffles 21 are located on the two side openings of the upper housing 11 and the lower housing 12, and the baffles 21 have an arc-shaped structure that matches the openings on both sides. The baffles 21 can fit tightly against the openings, effectively sealing the two sides of the upper housing 11 and the lower housing 12, preventing the material being crushed inside the equipment from leaking out from the side, avoiding material waste and the mess of the surrounding environment caused by the scattering of materials. At the same time, it can also block dust from overflowing from the side, maintain a relatively closed crushing environment inside the equipment, reduce the emission of dust to the outside, and ensure the air quality around the equipment and the cleanliness of the work site.

[0037] Furthermore, in the above technical solution, the lower two ends of the baffle 21 are rotatably connected to the inner walls of the lower housing 12 via protrusions. A connector 24 is fixedly installed on the outside of the baffle 21. The connector 24 is a movable structure, and a shaft 23 is movably installed at the front end of the connector 24. The end of the shaft 23 away from the connector 24 is movably connected to the output end of the cylinder 22. The connector 24 is installed on the outside of the baffle 21 as a movable structure and is movably connected with the shaft 23 and the cylinder 22, forming a transmission connection link between the cylinder 22 and the baffle 21. This allows the power output by the cylinder 22 to be accurately and effectively transmitted to the baffle 21, ensuring that the baffle 21 can rotate and open and close as expected. This movable connection method has a certain degree of flexibility and can adapt to the angle changes of the baffle 21 during rotation and the force conditions at different positions, ensuring stable and reliable force transmission without problems such as jamming or disengagement, making the overall operation of the opening and closing mechanism 2 smoother.

[0038] Furthermore, in the above technical solution, a crushing roller 5 is arranged inside the assembly of the upper shell 11 and the lower shell 12. A support base 7 is fixedly installed on the outside of one end of the lower shell 12, and a motor 6 is fixedly installed on the support base 7. One end of the crushing roller 5 is connected to the output end of the motor 6. The support base 7 provides a reliable mounting foundation for the motor 6, ensuring that the motor 6 can remain stable during operation and will not be displaced or loosened due to its own vibration or shaking during equipment operation. This ensures that the motor 6 can continuously and stably provide power to the crushing roller 5, drive the crushing roller 5 to operate normally, thereby ensuring that the crushing function of the equipment is effectively realized and maintaining the high material crushing efficiency of the equipment.

[0039] Furthermore, in the above technical solution, a cover plate is movably provided at the top of the guide hood 13 to cover or adjust the size of the top inlet of the guide hood 13, further reducing the impact of dust, improving the safety during operation, and limiting the size of the garbage thrown in, thereby reducing the probability of clogging the guide hood 13 and causing damage to the crushing roller 5.

[0040] The working process of the building material crushing equipment for rural construction provided by this utility model is as follows:

[0041] The operator first connects the external dust collection device to the power supply and starts it, putting it into standby dust collection mode. Then, the power switch of motor 6 is turned on, and motor 6 starts to run and drives crushing roller 5 to rotate at the set speed. At this time, the entire equipment enters the preparation state and waits for the feeding operation. The cooperative relationship between the various components has been established. Dust hood 4 is ready to capture the dust overflowing during the discharge process, and crushing roller 5 is ready to crush the input material.

[0042] Building materials are fed into the equipment through the feed port 8 via the guide hood 13. Under the guidance of the guide hood 13, the materials fall accurately into the crushing area where the crushing roller 5 is located. The materials begin to accumulate inside the equipment and gradually come into contact with the rotating crushing roller 5. During the feeding process, it is necessary to ensure that the material feeding speed is uniform so that the crushing roller 5 can process the incoming materials in an orderly manner, and avoid excessive material accumulation due to excessive feeding speed, which would affect the crushing effect.

[0043] If material gets stuck inside the crusher housing or crushing roller 5 during operation, causing the equipment to malfunction, stop the machine immediately. Then open the opening / closing mechanism 2, start the cylinder 22 to drive the baffle 21 to rotate, and the operator can enter the equipment through the openings on both sides. Use appropriate tools to remove the stuck material. During operation, pay attention to safety and avoid being scratched or injured by internal components. After removing the material, close the baffle 21. Before restarting the equipment, perform a simple inspection to ensure all components are functioning correctly before continuing operation.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
