Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a stone crushing device for building construction processing. Background Technology

[0002] Construction machinery is an important part of the equipment industry. It refers to the mechanical equipment necessary for comprehensive mechanized construction projects such as earthwork construction, road construction and maintenance, mobile lifting and loading operations, and various building projects. Among them, stone crushing equipment for construction processing is an industrial equipment used to crush large stones to the required particle size. It is widely used in mining, metallurgy, building materials, highways, railways, water conservancy and other industries. It achieves material crushing through mechanical principles such as extrusion, splitting, bending, impact and rolling.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Traditional equipment has a fixed screen aperture, which cannot be adjusted according to actual needs, resulting in the inclusion of oversized large-diameter gravel in the crushed stone. This necessitates an additional screening process or manual sorting, making the entire process cumbersome and inefficient. Large-diameter gravel needs to be transferred to other equipment or re-processed in the crusher; however, traditional equipment lacks a targeted screening design, leading to the repeated processing of a large amount of already qualified stone during secondary crushing. This not only increases energy consumption but also exacerbates equipment wear. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the screen aperture of the existing equipment is fixed and cannot be adjusted according to actual needs. Therefore, we propose a stone crushing equipment for building construction processing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a stone crushing device for building construction and processing, comprising a stone crushing body, a fixed frame installed on the surface of the stone crushing body, a vibrating frame installed at the bottom of the stone crushing body, a plurality of support legs fixedly connected to the bottom of the vibrating frame, an installation groove opened at one end of the vibrating frame, a screening plate slidably connected inside the installation groove, fixed blocks fixedly connected to both sides of the top of the screening plate, a circular groove opened at the top of the fixed block, a moving rod slidably connected inside the circular groove, a shaped pull plate fixedly connected to the top of the moving rod, two square fixing grooves opened on both sides of the top of the vibrating frame, and one end of the shaped pull plate slidably connected to the inside of the square fixing groove.

[0006] Preferably, the top and bottom of the mounting groove are provided with slots, and the top and bottom of both sides of the screening plate are fixedly connected with blocks, the surface of the blocks engaging with the inside of the slots.

[0007] Preferably, a plurality of rollers are installed on both sides of the screening plate, and the surface of the rollers is rotatably connected to the interior of the mounting groove.

[0008] Preferably, a magnetic block is fixedly connected inside the square fixing groove, and the magnetic block is magnetically connected to one end of the irregularly shaped pull plate.

[0009] Preferably, a spring is slidably connected to the surface of the movable rod, the top of the spring is fixedly connected to the top end inside the circular groove, and the bottom of the spring is fixedly connected to the movable rod.

[0010] Preferably, the surface of the movable rod has two sliding grooves, and the top of the circular groove is fixedly connected to two sliding blocks that cooperate with the sliding grooves. The surface of the sliding blocks is slidably connected to the inside of the sliding grooves.

[0011] Preferably, a square plate is fixedly connected inside the vibrating frame, and a rubber pad is installed on the top of the square plate, with the top of the rubber pad in contact with the bottom of the screening plate.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, by pulling the irregularly shaped pull plate, one end of the pull plate is disengaged from the inside of the square fixing groove. At this time, the limiting position of the screening plate inside the installation groove is released. The screening plate can then be replaced according to the current needs for stone size, using a screening plate with a different aperture. When the stone crushing body is operating, the crushed stone falls from the bottom of the crushing body onto the surface of the screening plate. The vibrating frame drives the screening plate to vibrate and screen, filtering out larger stones. These larger stones can then be crushed again. The screening plate can then be installed into the installation groove as needed. When inserting the screen plate into the mounting groove, push it in from one end. Once the screen plate is fully inserted into the groove, pull the shaped pull plate to insert one end into the square fixing groove, thus fixing the screen plate inside the mounting groove. By replacing screen plates with different aperture sizes, the output particle size can be controlled according to requirements, automatically screening out oversized large-diameter crushed stone, reducing manual intervention. During secondary crushing, qualified stone is prevented from being repeatedly processed, reducing the equipment's ineffective operating time. At the same time, it reduces the wear of vulnerable parts such as crushing hammers and liners, extending the equipment's service life. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a stone crushing device for building construction and processing, including a stone crushing body 1, a fixed frame 2 installed on the surface of the stone crushing body 1, a vibrating frame 3 installed at the bottom of the stone crushing body 1, a plurality of support legs 4 fixedly connected to the bottom of the vibrating frame 3, an installation groove 5 opened at one end of the vibrating frame 3, a screening plate 6 slidably connected inside the installation groove 5, fixed blocks 7 fixedly connected to both sides of the top of the screening plate 6, a circular groove 8 opened at the top of the fixed block 7, a moving rod 9 slidably connected inside the circular groove 8, a shaped pull plate 10 fixedly connected to the top of the moving rod 9, two square fixing grooves 11 opened on both sides of the top of the vibrating frame 3, one end of the shaped pull plate 10 slidably connected to the inside of the square fixing groove 11, by pulling the shaped pull plate 10, one end of the shaped pull plate 10 is disengaged from the inside of the square fixing groove 11, at this time the limiting position of the screening plate 6 inside the installation groove 5 is released, and the size of the stone can be adjusted according to the current needs. The screening plate 6 is replaced with a screening plate of a different aperture. When the stone crushing body 1 is running, the crushed stone falls from the bottom of the stone crushing body 1 onto the surface of the screening plate 6. The vibrating frame 3 drives the screening plate 6 to vibrate and screen. Larger stones are filtered out by the screening plate 6 and can be crushed again. When it is necessary to install the screening plate 6 into the installation groove 5, push the screening plate 6 into the installation groove 5 from one end. When the screening plate 6 is fully pushed into the installation groove 5, pull the irregular pull plate 10 so that one end of the irregular pull plate 10 enters the square fixing groove 11, thereby fixing the screening plate 6 inside the installation groove 5. By replacing the screening plate 6 with a different aperture, the output particle size can be strictly controlled, and oversized crushed stone can be automatically screened out, reducing manual intervention. During secondary crushing, qualified stone is avoided from being repeatedly processed, reducing the ineffective operating time of the equipment. At the same time, the wear of vulnerable parts such as crushing hammers and liners is reduced, and the service life of the equipment is extended.

[0017] Reference Figure 3 and Figure 5 As shown in this embodiment: the top and bottom of the mounting groove 5 are provided with slots 12, and the top and bottom of both sides of the screening plate 6 are fixedly connected with blocks 13. The surface of the blocks 13 engages with the inside of the slots 12. By engaging the surface of the blocks 13 with the inside of the slots 12, the screening plate 6 can be more stable inside the mounting groove 5.

[0018] Reference Figure 3 As shown in this embodiment: several rollers 14 are installed on both sides of the screening plate 6. The surface of the rollers 14 is rotatably connected to the inside of the mounting groove 5. By setting the rollers 14, the friction between the two can be reduced when the screening plate 6 is installed into the inside of the mounting groove 5, making the installation of the screening plate 6 easier and smoother.

[0019] Reference Figure 5As shown in this embodiment: a magnetic block 15 is fixedly connected inside the square fixing groove 11. The magnetic block 15 is magnetically connected to one end of the irregular pull plate 10. By setting the magnetic block 15, the magnetic block 15 is magnetically connected to the irregular pull plate 10. The irregular pull plate 10 is made of metal. This setting can make the irregular pull plate 10 more stable inside the square fixing groove 11 and will not loosen when the installation groove 5 drives the screening plate 6 to vibrate.

[0020] Reference Figure 4 As shown in this embodiment: a spring 16 is slidably connected to the surface of the moving rod 9. The top of the spring 16 is fixedly connected to the top end inside the circular groove 8, and the bottom of the spring 16 is fixedly connected to the moving rod 9. By setting the spring 16, the elasticity of the spring 16 abuts against the moving rod 9, which can drive the moving rod 9 to automatically reset, and at the same time restrict the movement of the moving rod 9.

[0021] Reference Figure 4 As shown in this embodiment: the surface of the moving rod 9 has two sliding grooves 17, and the top of the circular groove 8 is fixedly connected to two sliding blocks 18 that cooperate with the sliding grooves 17. The surface of the sliding block 18 is slidably connected to the inside of the sliding groove 17. By making the surface of the sliding block 18 slidably connected to the inside of the sliding groove 17, the movement position of the moving rod 9 can be restricted, avoiding unnecessary displacement when the moving rod 9 moves inside the circular groove 8, so that the moving rod 9 can drive the irregular pull plate 10 to accurately enter the inside of the square fixed groove 11.

[0022] Reference Figure 5 As shown in this embodiment: a square plate 19 is fixedly connected inside the vibrating frame 3. A rubber pad 20 is installed on the top of the square plate 19. The top of the rubber pad 20 is in contact with the bottom of the screening plate 6. By setting the square plate 19, the square plate 19 can support the bottom of the screening plate 6, which can increase the load-bearing capacity of the screening plate 6. The setting of the rubber pad 20 can make the square plate 19 and the screening plate 6 have a flexible contact, reducing the friction between the two.

[0023] Working principle: By pulling the irregularly shaped pull plate 10, one end of the irregularly shaped pull plate 10 is disengaged from the inside of the square fixing groove 11. At this time, the limiting position of the screening plate 6 inside the installation groove 5 is released. At this time, the screening plate 6 can be replaced according to the current needs of the stone size. By replacing it with a screening plate 6 with a different aperture, when the stone crushing body 1 is running, the crushed stone falls from the bottom of the stone crushing body 1 onto the surface of the screening plate 6. The vibrating frame 3 drives the screening plate 6 to vibrate and screen. Larger stones are filtered out by the screening plate 6 and can be crushed again. When it is necessary to install the screening plate 6, the screening plate 6 can be reinstalled. When installing the screen plate 6 into the mounting groove 5, push it in from one end of the mounting groove 5. Once the screen plate 6 is fully inserted into the mounting groove 5, pull the shaped pull plate 10, causing one end of the shaped pull plate 10 to enter the square fixing groove 11, thus fixing the screen plate 6 inside the mounting groove 5. By replacing the screen plate 6 with different aperture sizes, the output particle size can be strictly controlled, automatically screening out oversized crushed stone, reducing manual intervention. During secondary crushing, it avoids the repeated processing of qualified stone, reducing the equipment's ineffective operating time, and also reducing the wear of vulnerable parts such as the crushing hammer and liners. To extend the service life of the equipment, the surface of the locking block 13 engages with the inside of the locking groove 12, making the screening plate 6 more stable inside the mounting groove 5. The rollers 14 reduce friction between the screening plate 6 and the mounting groove 5, making installation easier and smoother. The spring 16, with its elasticity, abuts against the moving rod 9, thus driving the moving rod 9. Automatic reset, while restricting the movement of the moving rod 9. By making the surface of the sliding block 18 slide in the interior of the sliding groove 17, the movement position of the moving rod 9 can be restricted, avoiding unnecessary displacement when the moving rod 9 moves inside the circular groove 8. This allows the moving rod 9 to drive the irregularly shaped pull plate 10 to accurately enter the interior of the square fixed groove 11. By setting the square plate 19, which supports the bottom of the screening plate 6, the load-bearing capacity of the screening plate 6 can be increased. The setting of the rubber pad 20 can make the square plate 19 and the screening plate 6 in flexible contact, reducing the friction between the two.
