Abstract
Description
Technical Field
[0001] This application relates to the field of building equipment technology, specifically a crushing device for building construction. Background Technology
[0002] During construction, large stones may be present on site. In order to break these large stones into smaller ones, a jaw crusher is usually used.
[0003] Jaw crushers crush stones by squeezing them with a moving jaw plate, which works in conjunction with a fixed jaw plate. Over time, the ridges on the jaw plates wear down and flatten, resulting in a decrease in crushing efficiency. Therefore, the jaw plates need to be replaced. However, if only a portion of the ridges on the jaw plates is damaged, the entire jaw plate needs to be replaced, which leads to a waste of resources.
[0004] Therefore, this application provides a crushing stone device for building construction to solve the above-mentioned problems. Utility Model Content
[0005] This application provides a construction stone crushing device, which aims to solve the problems mentioned in the background art, such as the problem that the ridges of the jaw plate of the existing jaw crusher will become locally flattened and damaged during use, thus requiring the replacement of the entire jaw plate and resulting in resource waste.
[0006] To achieve the above objectives, this application provides the following technical solution: a construction stone crushing device, comprising a body, a movable jaw body disposed inside the body, and a drive device disposed at a drive end of the movable jaw body for driving the movable jaw body to move;
[0007] To facilitate jaw plate assembly replacement: the front of the movable jaw body is provided with a jaw plate assembly for crushing rocks; the top of the jaw plate assembly is provided with mounting bolts for fixing the jaw plate assembly to the movable jaw body; the bottom of the jaw plate assembly is provided with a snap-fit component for supporting the jaw plate assembly; the jaw plate assembly includes a central jaw plate and side jaw plates symmetrically arranged on both sides of the central jaw plate; connecting blocks for connecting to the side jaw plates are symmetrically arranged on both sides of the central jaw plate. When the central jaw plate or the side jaw plate is partially damaged, the damaged central jaw plate or side jaw plate can be removed and replaced by pulling out the supporting block and then removing the mounting bolts at the corresponding positions. This allows for installation and connection with the undamaged central jaw plate or side jaw plate, thus avoiding the waste of resources caused by replacing the entire jaw plate assembly due to partial damage.
[0008] Preferably, to facilitate the connection between the middle jaw plate and the side jaw plates: the outer wall of the middle jaw plate is fixedly connected to one side of the connecting block, and the side jaw plate has an insertion groove for the connecting block to engage on the side facing the middle jaw plate. By inserting the connecting block into the insertion groove, the shape of the connecting block and the insertion groove themselves prevents separation between the middle jaw plate and the side jaw plate, thus enabling rapid installation of the middle jaw plate and the side jaw plate.
[0009] Preferably, the horizontal cross-section of both the connecting block and the insertion slot is T-shaped.
[0010] Preferably, for a stable connection between the top of the jaw plate assembly and the movable jaw body: the top of the middle jaw plate and the side jaw plate are respectively provided with first bolt holes, and the mounting bolts are inserted into the first bolt holes. The front of the movable jaw body is provided with second bolt holes for the mounting bolts to be inserted. By simultaneously inserting mounting bolts into the first bolt holes of the middle jaw plate and the side jaw plate and the second bolt hole on the front of the movable jaw body, the tops of both the middle jaw plate and the side jaw plate are fixedly connected to the movable jaw body, ensuring the stability of the installation of the middle jaw plate and the side jaw plate.
[0011] Preferably, for positioning the jaw plate assembly during installation on the movable jaw body: The back surfaces of the central jaw plate and the side jaw plates are respectively fixedly connected to limiting blocks for engaging with the snap-fit component. The bottom of each limiting block has a first inclined surface, and the bottom surface of the front of the movable jaw body has a limiting groove for inserting the limiting block. Through the limiting groove at the bottom of the movable jaw body, during installation of the central jaw plate and the side jaw plates, the limiting blocks installed on the back surfaces of the central jaw plate and the side jaw plates contact the top of the inner wall of the limiting groove, restricting the movement of the central jaw plate and the side jaw plates, thereby ensuring that the first bolt hole and the second bolt hole are aligned.
[0012] Preferably, to ensure stable installation of the jaw plate assembly at the bottom: the snap-fit component includes a support block, the top of which, at the end away from the moving jaw body, has a second inclined surface for engaging with the first inclined surface, and the front of the limiting groove has a mounting groove for inserting the support block. Through the J-shape of the support block, the top is inserted into the mounting groove, and the second inclined surface at the bottom abuts against the first inclined surface, thereby providing support for the middle jaw plate and the side jaw plates, preventing them from sliding down and ensuring stable installation of the middle jaw plate and the side jaw plates.
[0013] Preferably, the vertical cross-section of the support block is J-shaped.
[0014] This application, through the design of the jaw plate assembly, mounting bolts, and snap-fit components, allows for the separation of the support block from the moving jaw body when partial damage occurs to the middle jaw plate or side jaw plate. Then, the mounting bolts can be removed, enabling the middle jaw plate or side jaw plate to be disassembled separately. This allows for the individual disassembly of the partially damaged middle jaw plate or side jaw plate without replacing the entire jaw plate assembly due to partial damage, thus saving resources.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] This embodiment provides a crushing stone device for building construction, such as... Figure 1-7As shown, it includes a body 1, a movable jaw 2 disposed inside the body 1, and a drive device 3 with a drive end for driving the movable jaw 2 to move.
[0026] To facilitate the replacement of the jaw plate assembly 4: the front of the movable jaw body 2 is provided with a jaw plate assembly 4 for crushing rocks. The top of the jaw plate assembly 4 is provided with mounting bolts 5 for fixing the jaw plate assembly 4 to the movable jaw body 2, and the bottom of the jaw plate assembly 4 is provided with a snap-fit component 6 for supporting the jaw plate assembly 4. The jaw plate assembly 4 includes a central jaw plate 41 and side jaw plates 42 symmetrically arranged on both sides of the central jaw plate 41. Connecting blocks 43 for connecting to the side jaw plates 42 are symmetrically arranged on both sides of the central jaw plate 41. When the central jaw plate 41 or the side jaw plate 42 is partially damaged, the damaged central jaw plate 41 or side jaw plate 42 can be removed and replaced by pulling out the support block 61 and then removing the mounting bolts 5 at the corresponding positions. This allows for installation and connection with the undamaged central jaw plate 41 or side jaw plate 42, thus avoiding the waste of resources caused by replacing the entire jaw plate assembly 4 due to partial damage.
[0027] Specifically, to facilitate the connection between the middle jaw plate 41 and the side jaw plates 42: the outer wall of the middle jaw plate 41 is fixedly connected to one side of the connecting block 43, and the side jaw plate 42 has an insertion groove for the connecting block 43 to engage on the side facing the middle jaw plate 41. Both the connecting block 43 and the insertion groove have a T-shaped horizontal cross-section. By interlocking the connecting block 43 with the insertion groove, the shapes of the connecting block 43 and the insertion groove themselves prevent separation between the middle jaw plate 41 and the side jaw plates 42, enabling rapid installation of the middle jaw plate 41 and the side jaw plates 42. The size of the connecting block 43 matches the size of the insertion groove. Since both the connecting block 43 and the insertion groove are T-shaped, inserting the connecting blocks 43 on both sides of the middle jaw plate 41 into the insertion grooves of the side jaw plates 42 prevents lateral movement between the middle jaw plate 41 and the side jaw plates 42, ensuring rapid connection and installation of the middle jaw plate 41 and the side jaw plates 42.
[0028] Specifically, for a stable connection between the top of the jaw plate assembly 4 and the movable jaw body 2: the top of the middle jaw plate 41 and the side jaw plate 42 are respectively provided with first bolt holes, and the mounting bolts 5 are inserted into the first bolt holes. The front of the movable jaw body 2 is provided with second bolt holes for the mounting bolts 5 to be inserted. By simultaneously inserting the mounting bolts 5 into the first bolt holes of the middle jaw plate 41 and the side jaw plate 42 and the second bolt hole on the front of the movable jaw body 2, the tops of both the middle jaw plate 41 and the side jaw plate 42 are fixedly connected to the movable jaw body 2, ensuring the stability of the installation of the middle jaw plate 41 and the side jaw plate 42.
[0029] Specifically, for the positioning of the jaw plate assembly 4 during installation on the movable jaw body 2: The back sides of the middle jaw plate 41 and the side jaw plates 42 are respectively fixedly connected with limiting blocks 44 for engaging with the snap-fit component 6. The bottom of the limiting block 44 has a first inclined surface, and the bottom of the front side of the movable jaw body 2 has a limiting groove 7 for inserting the limiting block 44. Through the limiting groove 7 at the bottom of the movable jaw body 2, during installation of the middle jaw plate 41 and the side jaw plates 42, the limiting blocks 44 installed on the back sides of the middle jaw plate 41 and the side jaw plates 42 contact the top of the inner wall of the limiting groove 7, restricting the movement of the middle jaw plate 41 and the side jaw plates 42, thereby ensuring that the first bolt hole and the second bolt hole are aligned. The middle jaw plate 41 or the side jaw plate 42 is welded and fixed to the part that contacts the limiting block 44. The first inclined surface of the limiting block 44 faces away from the moving jaw body 2. The top of the limiting block 44 and the top of the inner wall of the limiting groove 7 are both flat. So when the middle jaw plate 41 and the side jaw plate 42 are installed, the contact surfaces of the limiting block 44 and the limiting groove 7 fit together, restricting the movement of the middle jaw plate 41 and the side jaw plate 42, thereby ensuring that the positions of the first bolt hole and the second bolt hole coincide, which facilitates the installation of the bolt 5.
[0030] Furthermore, to ensure stable installation of the jaw plate assembly 4 at the bottom: the snap-fit component 6 includes a support block 61. The top of the support block 61, at the end furthest from the moving jaw body 2, has a second inclined surface 62 for engaging with the first inclined surface. The front of the limiting groove 7 has a mounting groove 8 for inserting the support block 61. The vertical cross-section of the support block 61 is J-shaped. Through the J-shape of the support block 61, the top is inserted into the mounting groove 8, and the second inclined surface 62 at the bottom engages with the first inclined surface, thereby providing support for the middle jaw plate 41 and the side jaw plates 42. This prevents the middle jaw plate 41 and the side jaw plates 42 from sliding down, ensuring stable installation of the middle jaw plate 41 and the side jaw plates 42. The J-shaped support block 61 has its top end inserted into the mounting groove 8 and fixed to the moving jaw body 2 with bolts. The second inclined surface 62 fits against the first inclined surface, thus restricting the jaw plate assembly 4 and preventing the bottom of the jaw plate assembly 4 from moving away from the moving jaw body 2. At the same time, the support block 61 supports the bottom of the jaw plate assembly 4, preventing slippage in the event of breakage of the middle jaw plate 41 and the side jaw plates 42. This ensures stable fixed installation between the bottom of the jaw plate assembly 4 and the moving jaw body 2. When installing the middle jaw plate 41, first engage the middle jaw plate 41 with the side jaw plate 42 and the limiting groove 7 of the moving jaw body 2, then install the mounting bolts 5, and finally insert the support block 61 into the mounting groove 8. The support block 61 is fixed to the mounting groove 8, thus completing the installation of the middle jaw plate 41, the side jaw plate 42 and the moving jaw body 2. When it is necessary to disassemble the middle jaw plate 41 and the side jaw plate 42, the support block 61 must be removed first, so that the support block 61 is pulled out from the bottom of the moving jaw body 2, and then the mounting bolts 5 at the corresponding positions are removed to disassemble the damaged middle jaw plate 41 or the side jaw plate 42.
[0031] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
