Description

Technical Field

[0001] This utility model relates to the field of crushing equipment, and in particular to an engineering crusher. Background Technology

[0002] A large amount of construction waste is often generated during the demolition process. In some cases, crushers are used to crush the construction waste before it is transported out, especially in projects containing a lot of materials such as wood, composite materials, and metal frames (doors, windows, roofs). This part of the construction waste (in rod or sheet form) has poor compressibility when transported directly, resulting in low efficiency of single-vehicle transportation. It is necessary to crush the construction waste on-site before transfer.

[0003] Currently, during the aforementioned construction projects, waste is often processed using methods such as the construction waste feeding, crushing, and screening structure disclosed in patent CN220759413U, and the tracked chassis mobile jaw crusher disclosed in patent CN118385019B. These crushers are mostly suitable for conditions where concrete construction waste is the primary material, and their feed hoppers are often designed as inclined screening and vibrating feed structures. The applicant has discovered that when crushing construction waste for the aforementioned conditions, the top of the crushing chamber is designed to be open to facilitate the entry of rod-shaped or sheet-shaped waste into the crushing chamber. During the compression or shearing crushing process, the waste easily accumulates elastic potential energy and then splashes outward, as in the equipment in patent CN118385019B. The splashed waste not only increases the difficulty of on-site cleanup but also poses safety hazards to on-site equipment and workers.

[0004] Based on this, this application proposes an engineering crusher to solve the aforementioned problems. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides an engineering crusher, comprising a top-open crushing chamber, crushing components disposed within the crushing chamber, and a feed hopper disposed on one side of the crushing chamber. The crusher has two opposing side guards at the top of the crushing chamber, forming a feeding space between the two side guards. The crusher also includes a protective cover disposed on the side of the side guards away from the feed hopper. The protective cover comprises a first plate segment and a second plate segment. The lower end of the first plate segment is hinged to the casing of the crusher. The second plate segment is disposed at the upper end of the first plate segment and extends to the upper side of the crushing chamber. The first plate segment is rotatable to drive the second plate segment to rotate outward from the crushing chamber.

[0007] Furthermore, the first plate segment and the second plate segment are configured to be detachably connected.

[0008] Furthermore, the outer side of the first plate segment is provided with a plurality of support tubes at intervals; the second plate segment includes a longitudinal plate that can fit against the inner side of the first plate segment and a transverse plate fixedly connected to the longitudinal plate. The transverse plate can extend to the upper side of the crushing chamber, and the outer side of the longitudinal plate is provided with inserts for inserting the support tubes at the positions corresponding to each of the support tubes.

[0009] Furthermore, the longitudinal plate is provided with a supporting rib on the upper side of the insert rib; a guide plate is formed on the top of the first plate segment, the upper end of the supporting tube extends to the guide plate, the guide plate is provided with a through hole corresponding to the position of the supporting tube, and the supporting rib can abut against and limit the guide plate.

[0010] Furthermore, an inclined reinforcing plate is provided on the inner side of the longitudinal plate, and the reinforcing plate connects the longitudinal plate and the transverse plate.

[0011] Alternatively, the second plate segment may include a longitudinal plate that can be fitted to the inner side of the first plate segment and a transverse plate mounted on top of the longitudinal plate, the longitudinal plate being slidably mounted to the inner side of the first plate segment.

[0012] Furthermore, the horizontal plate is rotatably mounted on the vertical plate, and the horizontal plate can rotate to switch between a folded state and a covered state.

[0013] When folded, the horizontal plate can be folded to the side of the vertical plate, and when unfolded, the horizontal plate is perpendicular to the vertical plate.

[0014] Furthermore, a support rod is provided between the horizontal plate and the vertical plate, one end of the support rod being hinged to one of the horizontal plate or the vertical plate, and the other end being detachably connected to the other of the horizontal plate or the vertical plate.

[0015] Furthermore, the first plate segment and the second plate segment are integrally connected.

[0016] Furthermore, the feed hopper is rotatably mounted on the frame of the crusher.

[0026] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0027] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0028] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] In this utility model, such as Figure 1-6 As shown, an engineering crusher is provided, including a crushing chamber 1 with an open top, crushing components 2 disposed within the crushing chamber 1, and a feed hopper 3 disposed on one side of the crushing chamber 1; the crusher has two opposing side guard plates 4 at the top of the crushing chamber 1, forming a feeding space for the crushing chamber 1 between the two side guard plates 4; the crusher also includes a protective cover disposed on the side of the side guard plate 4 away from the feed hopper 3, the protective cover including a first plate segment 5 and a second plate segment 6, the lower end of the first plate segment 5 being hinged to the casing of the crusher, the second plate segment 6 being disposed at the upper end of the first plate segment 5 and extending to the upper side of the crushing chamber 1, the first plate segment 5 being rotatable to drive the second plate segment 6 to rotate outward of the crushing chamber 1.

[0032] When using the crusher of this utility model, such as Figure 1 and Figure 3As shown, after the crusher is placed at the work site, the protective cover is rotated outwards from the crushing chamber 1, causing the second plate segment 6 to deviate from directly above the crushing chamber 1. The material to be crushed can be loaded into the top of the crushing chamber 1 and the feed hopper 3 using the excavator's hydraulic grab or excavator bucket. The two side guard plates 4 can constrain the material on the upper side of the crushing chamber 1. At this time, the protective cover can be rotated so that at least part of the second plate segment 6 is located on the upper side of the crushing chamber 1. This allows the protective cover to constrain the splashing material when it splashes during the crushing process, thereby reducing the splashing of material to the outside of the crusher.

[0033] The beneficial effects of this utility model are as follows: Figures 1 to 6 In the illustrated embodiment, the protective cover is positioned on the side of the side guard plate 4 away from the feed hopper 3. This allows the protective cover to provide focused protection for the left side of the crusher, while most of the material splashed from the right side of the protective cover can be caught by the feed hopper 3, further reducing the risk. It is clear that this invention, through optimized placement and structure of the protective cover, works in conjunction with the feed hopper 3 to provide protection against splashed material, thereby further improving the on-site working environment.

[0034] It should be noted that the rotation operation of the protective cover during use of this utility model is combined with... Figure 1 and Figure 3 Further explanation of the tilting feed hopper 3: When the feed hopper 3 tilts and tilts to pour material into the crushing chamber 1, the protective cover can be rotated to the left to open, preventing the protective cover from affecting the material in the feed hopper 3 from entering the crushing chamber 1. After the material in the feed hopper 3 has finished pouring, the protective cover is tilted back until the second plate segment 6 extends to the upper side of the crushing chamber 1. When using a vibrating feed hopper as in the present, the protective cover can be in the state where the second plate segment 6 extends to the upper side of the crushing chamber 1 during the process of the feed hopper conveying material to the crushing chamber 1.

[0035] In a preferred embodiment, specifically regarding the structure of this utility model, the first plate segment 5 and the second plate segment 6 are configured to be detachably connected. For example... Figures 1 to 3 As shown, this allows the second plate segment 6 to be removed during the transfer of the crusher, reducing the height of the crusher at the protective cover position and facilitating transportation. The second plate segment 6 can also be removed in some applications handling non-rod-shaped or flaky materials (where preventing material splashing is not required).

[0036] It should be noted that this utility model is in Figure 3 In the illustrated embodiment, the crusher 2 is described according to a roller crushing structure, but this is not intended to limit the present invention. In optional embodiments, other forms of crusher 2 may also be used, such as jaw crusher 2.

[0037] exist Figure 3In the illustrated embodiment, more specifically regarding the structure of this utility model, the outer side of the first plate segment 5 is provided with a plurality of support tubes 7 at intervals; the second plate segment 6 includes a longitudinal plate 601 that can fit against the inner side of the first plate segment 5 and a transverse plate 602 fixedly connected to the longitudinal plate 601. The transverse plate 602 can extend to the upper side of the crushing chamber 1, and the outer side of the longitudinal plate 601 is provided with inserting ribs 8 corresponding to the positions of each support tube 7, which can be inserted into the support tube 7.

[0038] like Figures 1 to 3 As shown, the first plate segment 5 is equipped with a support tube 7, which increases the structural stability of the first plate segment 5. The insert rib 8 of the second plate segment 6 allows the insert rib 8 to be inserted into the support tube 7, and the longitudinal plate 601 is attached to the inner side of the first plate segment 5, thereby achieving the insertion connection between the first plate segment 5 and the second plate segment 6, and facilitating the connection between the first plate segment 5 and the second plate segment 6.

[0039] exist Figure 1 In the illustrated embodiment, for the structure of this utility model, more specifically, the longitudinal plate 601 is provided with a supporting rib 9 on the upper side of the insert rib 8; a guide plate 10 is formed on the top of the first plate segment 5, the upper end of the supporting tube 7 extends to the guide plate 10, and the guide plate 10 is provided with a through hole corresponding to the position of the supporting tube 7.

[0040] like Figure 2 As shown, by setting a guide plate 10, the second plate segment 6 and the first plate segment 5 can be fixedly positioned by the support rib 9 abutting against the guide plate 10; by setting the support rib 9, the longitudinal plate 601 can be structurally strengthened, thereby further improving the structural stability of the second plate segment 6.

[0041] exist Figure 1 In the illustrated embodiment, to further specify the structure of this utility model, an inclined reinforcing plate 11 is also provided on the inner side of the longitudinal plate 601, and the reinforcing plate 11 connects the longitudinal plate 601 and the transverse plate 602. Figure 2 and 3 As shown, by setting the reinforcing plate 11, the structural stability of the first plate segment 5 can be further improved.

[0042] For the insertion connection between the first plate segment 5 and the second plate segment 6, to prevent the first plate segment 5 and the second plate segment 6 from separating arbitrarily, in a preferred embodiment, the insert rib 8 can be interference-fitted with the insert tube; or as... Figure 3 As shown, by controlling the flipping angle of the protective cover, when the protective cover rotates outward of the crushing chamber 1 and the horizontal plate 602 deviates from the upper side of the crushing chamber 1, the vertical plate 601 remains tilted to the left and upward, thereby preventing the second plate end from separating from the first plate segment 5 due to gravity.

[0043] In an alternative embodiment, such as Figures 4 to 6 As shown, regarding the arrangement of the second plate segment 6 and the first plate segment 5, more specifically, the second plate segment 6 includes a vertical plate 601 that can be attached to the inner side of the first plate segment 5 and a horizontal plate 602 installed on the top of the vertical plate 601. The vertical plate 601 is slidably installed on the inner side of the first plate segment 5.

[0044] like Figures 4 to 6 As shown, this allows the second plate segment 6 to be lowered during the transfer of the crusher, thereby reducing the height of the protective cover and facilitating transportation.

[0045] exist Figure 4 In the illustrated embodiment, the specific structure for the slidable arrangement of the first plate segment 5 and the second plate segment 6 is further detailed as follows: Figure 4 and Figure 5 The outer side of the longitudinal plate 601 of the second plate segment 6 is provided with a steel bar 12, and the outer side of the first plate segment 5 is provided with a support pipe 7. The lower end of the steel bar 12 is inserted into the support pipe 7. The longitudinal plate 601 of the second plate segment 6 is attached to the inner side of the first plate segment 5, thereby realizing the sliding setting of the first plate segment 5 relative to the second plate segment 6.

[0046] Regarding the fixing of the first plate segment 5 and the second plate segment 6, preferably, after the second plate segment 6 reaches a predetermined sliding position relative to the first plate segment 5, it can be fixed between the longitudinal plate 601 and the second plate segment 6 by bolts, specifically as follows: Figure 5 As shown, a connecting hole can be provided at the upper end of the first plate segment 5, and fixing holes can be provided at the upper and lower ends of the longitudinal plate 601 respectively, so that the two fixing holes can be fixed in the corresponding positions by bolts when they correspond to the connecting holes respectively.

[0047] In alternative embodiments, the first plate segment 5 and the second plate segment 6 can also be slidably configured in other ways, such as by setting a hydraulic cylinder between the first plate segment 5 and the second plate segment 6, and driving the second plate segment 6 to slide relative to the first plate segment 5 through the hydraulic cylinder.

[0048] exist Figure 4 In the illustrated embodiment, a further optimization of the present invention is that the horizontal plate 602 is rotatably mounted on the vertical plate 601, and the horizontal plate 602 can rotate to switch between a folded state and a covering state; when folded, the horizontal plate 602 can be folded to the side of the vertical plate 601, and when unfolded, the horizontal plate 602 is perpendicular to the vertical plate 601.

[0049] like Figure 6As shown, this allows the horizontal plate 602 to be rotated to a folded state when processing non-rod-shaped or sheet-shaped materials (where preventing material splashing is not required). This reduces the impact of the horizontal plate 602 on the upper feed of the crushing chamber 1. When a protective cover is required, as... Figure 4 As shown, the horizontal plate 602 is then rotated to an unfolded state perpendicular to the vertical plate 601.

[0050] exist Figure 4 In the illustrated embodiment, to further specify the structure of this utility model, a support rod 13 is provided between the horizontal plate 602 and the vertical plate 601. One end of the support rod 13 is hinged to one of the horizontal plate 602 or the vertical plate 601, and the other end is detachably connected to the other of the horizontal plate 602 or the vertical plate 601.

[0051] like Figure 4 As shown, the lower end of the support rod 13 is hinged to the longitudinal plate 601, and the upper end is bolted to the transverse plate 602. This allows the transverse plate 602 to be supported and fixed when it is unfolded, thus keeping it in the unfolded state. When the transverse plate 602 needs to be folded, the upper end of the support rod 13 can be separated from the transverse plate 602 and the support rod 13 can be folded to the side of the longitudinal plate 601. Then the transverse plate 602 can be rotated to the folded state. At this time, the first plate segment 5 can be rotated to the end position of the side guard plate 4. The first plate segment 5 and the second plate segment 6, together with the two side guard plates 4, form the feeding space of the crushing chamber 1.

[0052] In the foregoing embodiments, the first plate segment 5 and the second plate segment 6 of the protective cover are both separate structures. This is not a limitation of the present invention. In alternative embodiments, the first plate segment 5 and the second plate segment 6 can also be integrally connected.

[0053] In the illustrated embodiment, the feed hopper 3 is rotatably mounted on the frame of the crusher.

[0054] It should be noted that in the illustrated embodiment, the first plate segment 5 is rotated by the first oil cylinder, and the feed hopper 3 is rotated by the second oil cylinder.

[0055] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0056] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
