Description

Technical Field

[0001] This utility model belongs to the technical field of jaw crushers, specifically, it relates to a smart construction site waste treatment equipment. Background Technology

[0002] In the construction of smart construction sites, the resource utilization of construction waste is a crucial link in achieving green construction and sustainable development. After processing such as crushing and screening, construction waste can be processed into building materials such as recycled aggregates and recycled bricks, realizing resource recycling. Currently, the construction waste crushing equipment commonly used on construction sites mostly adopts the jaw crusher structure, which crushes materials by compressing them through the relative movement between the movable jaw plate and the fixed jaw plate. It has advantages such as reliable structure and convenient maintenance in the field of construction waste treatment.

[0003] However, the discharge opening size of existing jaw crushers is usually a fixed structure or requires manual adjustment during machine shutdown, making it difficult to dynamically adapt to the presence of hard debris such as reinforcing bars and wires in the feed. When processing concrete blocks containing reinforcing bars, the bars can easily become stuck in the narrow area of ​​the crushing chamber, causing the equipment to overload and shut down. Although some existing equipment is equipped with spring or hydraulic safety devices that can increase the discharge opening to release pressure in case of overload, these devices can only alleviate the obstruction and cannot actively identify the type and location of the obstruction, nor can they automatically discharge the stuck reinforcing bars from the crushing chamber. In addition, the manual adjustment of the discharge opening size relies on machine shutdown, which is time-consuming and has limited accuracy, affecting the uniformity of the crushed particle size and the subsequent resource utilization effect. Therefore, existing technologies still have limitations in adaptability for the continuous and efficient crushing of construction waste containing reinforcing bars.

[0004] Based on this, the present invention proposes a smart construction site waste treatment device to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide a smart construction waste treatment equipment to deal with the problem of machine stoppage caused by hard debris during the crushing of reinforced concrete blocks. It can achieve dynamic adaptation of the discharge gap of the crushing chamber and autonomous discharge of foreign objects without interrupting continuous operation, thereby maintaining a stable and efficient crushing condition.

[0006] To achieve the above objectives, the basic concept of the technical solution adopted by this utility model is as follows: The intelligent construction site waste treatment equipment includes a drive mechanism, a main frame, a swing crushing mechanism, and a gap adaptive mechanism. The drive mechanism includes a drive motor and an eccentric shaft. The drive motor is fixedly installed on one side of the main frame and is poweredly connected to the pulley at the end of the eccentric shaft via a belt. The eccentric shaft is rotatably installed on the main frame and is connected to the upper end of the moving jaw plate mounting bracket. The swing crushing mechanism is installed inside the main frame; The gap adaptive mechanism is installed at the lower end of the main frame and matches the moving jaw plate mounting bracket.

[0007] In a preferred embodiment, the oscillating crushing mechanism includes a stationary jaw plate and a moving jaw plate. The stationary jaw plate is detachably installed on the feed port side of the main frame, and the moving jaw plate is detachably installed on the side of the moving jaw plate mounting bracket near the stationary jaw plate, forming a crushing chamber between the stationary jaw plate and the moving jaw plate.

[0008] In a preferred embodiment, the upper end of the stationary jaw plate is fixedly installed on the inner side of the front wall panel of the front stationary jaw plate of the main frame by a threaded post, and the lower end is tightly attached to the inner wall of the front wall panel by gravity, and a plurality of threaded sleeves are threadedly connected to the threaded post.

[0009] In a preferred embodiment, the upper end of the moving jaw plate is mounted on the moving jaw plate mounting frame near the stationary jaw plate by a moving jaw tie rod bolt, and the lower end is attached to the moving jaw plate mounting frame near the stationary jaw plate; a side guard plate is also provided on the inner side of the main frame, and the side guard plate is located on both sides of the crushing chamber.

[0010] In a preferred embodiment, the clearance adaptive mechanism includes a hydraulic actuator and a contact pressure sensing element; The hydraulic actuator is a double-stroke cylinder, which is fixedly installed on the bottom load-bearing beam of the main frame, and its piston rod is connected to the adjusting block. The adjusting block is connected to the moving jaw plate mounting bracket through the thrust plate. The contact pressure sensing element is a thin-film pressure sensing device installed on the side of the moving jaw plate mounting bracket near the moving jaw plate.

[0011] In a preferred embodiment, the thrust plate is inclinedly disposed between the moving jaw plate mounting bracket and the adjusting block, and matches the slots on the moving jaw plate mounting bracket and the adjusting block.

[0012] In a preferred embodiment, the adjusting block is movably installed between the guide steel column and the guide steel plate on the main frame, and a rubber buffer pad is also provided between the adjusting block and the rear side wall panel of the main frame.

[0013] In a preferred embodiment, the clearance adaptive mechanism further includes a linkage push rod, which is movably installed between the moving jaw plate mounting bracket and the rear side wall of the main frame and extends to the outside of the rear side wall. A spring is sleeved on the portion of the linkage push rod extending to the outside of the rear side wall, and the other end of the spring contacts a tightening nut. The tightening nut is threadedly connected to the linkage push rod.

[0014] In a preferred embodiment, the spring is in a stretched state when the movable jaw plate is in the standard working position.

[0015] In a preferred embodiment, the main frame is a rigid box structure, comprising a front side panel, a rear side panel, and left and right side panels, which are combined into a closed cavity by high-strength fasteners.

[0016] In a preferred embodiment, the working surfaces of both the stationary jaw plate and the moving jaw plate are provided with V-shaped teeth at a 45-degree angle, and each tooth surface is assembled independently.

[0017] Compared with the prior art, this utility model provides a smart construction site waste treatment device, which has the following beneficial effects: A mechanical linkage system consisting of a hydraulic actuator, thrust plate, adjusting block, guide assembly, and buffer structure is installed between the moving jaw plate mounting frame and the main frame. Combined with contact pressure detection elements attached to the inner wall of the moving jaw plate mounting frame, an integrated physical adjustment mechanism for pressure sensing and gap response is constructed. When a steel bar becomes stuck in the crushing chamber, causing a sudden pressure increase, the system automatically triggers a gap expansion action without manual intervention. Spring-assisted power accelerates the response, allowing the stuck material to be discharged under gravity and material flow, preventing equipment shutdown due to overload. The entire adjustment process is completed while the equipment is running, without interrupting the production process and ensuring the continuity of crushing operations. Simultaneously, because the gap reset action is precisely controlled by the hydraulic actuator, the outlet size of the crushing chamber recovers with high consistency, and the output particle size fluctuation is small, which is beneficial to the stable operation of subsequent screening and resource utilization processes. Core components such as the stationary and moving jaw plates adopt a modular tooth surface design; after localized wear, only the corresponding rack needs to be replaced, reducing maintenance costs. The main frame adopts a multi-layered combination of dissimilar materials and a high-strength fastening structure, which effectively resists the impact load of materials containing steel reinforcement and extends the service life of the whole machine.

[0021] The structure of this smart construction site waste treatment equipment will be further described in detail below with reference to the accompanying drawings and embodiments of this utility model.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] The following is combined with Figures 1 to 8 This invention describes a smart construction site waste treatment device.

[0027] A smart construction waste processing device is specifically designed for crushing operations involving reinforced concrete blocks. It includes a drive mechanism, a main frame 4, a swing crushing mechanism, and a gap adaptive mechanism. The drive mechanism comprises a drive motor 1 and an eccentric shaft 10. The drive motor 1 is fixedly mounted on one side of the main frame 4 and is poweredly connected to a pulley 2 at the end of the eccentric shaft 10 via a belt 3. The drive motor 1 drives the eccentric shaft 10 to rotate. The eccentric shaft 10 is rotatably mounted on the main frame 4 and connected to the upper end of a moving jaw plate mounting frame 7. During operation, the rotation of the eccentric shaft 10 drives the upper end of the moving jaw plate mounting frame 7 to reciprocate, cooperating with the swing crushing mechanism to crush the material. The swing crushing mechanism is installed inside the main frame 4 and is used for crushing the material. The gap adaptive mechanism is installed at the lower end of the main frame 4 and works in conjunction with the moving jaw plate mounting bracket 7. It adaptively adjusts the lower end position of the moving jaw plate mounting bracket 7 to adjust the gap width of the discharge port, so as to facilitate the discharge of hard foreign objects that are stuck.

[0028] In one specific implementation, such as Figure 1 , Figure 2 and Figure 3 As shown, the oscillating crushing mechanism includes a stationary jaw plate 5 and a moving jaw plate 6. The stationary jaw plate 5 is detachably installed on the feed port side of the main frame 4, and the moving jaw plate 6 is detachably installed on the side of the moving jaw plate mounting bracket 7 near the stationary jaw plate 5, forming a crushing chamber for material crushing between the stationary jaw plate 5 and the moving jaw plate 6.

[0029] Specifically, the upper end of the stationary jaw plate 5 is fixedly installed on the inner side of the front wall panel 9 of the front stationary jaw plate of the main frame 4 by means of threaded post 21, and the lower end is tightly attached to the inner wall of the front wall panel 9 by gravity. Several threaded sleeves 22 are threadedly connected to the threaded post 21 so that the position of the threaded sleeves 22 can be adjusted as needed during use to adjust the installation inclination of the stationary jaw plate 5.

[0030] Specifically, the upper end of the moving jaw plate 6 is mounted on the moving jaw plate mounting frame 7 near the stationary jaw plate 5 by the moving jaw tie rod bolt 11, and the lower end is attached to the moving jaw plate mounting frame 7 near the stationary jaw plate 5 by gravity, so as to realize the detachable installation of the moving jaw plate 6.

[0031] Specifically, a side guard plate 23 is also provided on the inner side of the main frame 4. The side guard plate 23 is located on both sides of the crushing chamber and is used to strengthen the guard plate of the main frame 4 on both sides of the crushing chamber.

[0032] In one specific implementation, such as Figure 1 , Figure 2 and Figure 3As shown, the main frame 4 is a rigid box structure, comprising a front side panel 9, a rear side panel, and left and right side panels, which are assembled into a closed cavity using high-strength fasteners. The front and rear side panels are made of 30 mm thick low-alloy high-strength structural steel plates, while the left and right side panels are made of 40 mm thick wear-resistant alloy steel plates. All high-strength fasteners are 24 mm diameter threaded connectors with a tensile strength of 10.9 grade, with through holes pre-drilled along the edges of the side panels and fitted with matching nuts, forming an overall impact-resistant load-bearing system.

[0033] In one specific implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, both the stationary jaw plate 5 and the moving jaw plate 6 are integrally cast from high manganese steel. The working surface has a V-shaped tooth structure with a 45-degree included angle and a tooth peak height of 25 mm. Each tooth surface is assembled independently and can be disassembled and replaced individually after wear, without the need for overall replacement.

[0034] In one specific implementation, such as Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the gap adaptive mechanism includes a hydraulic actuator 8 and a contact pressure detection element 18. The hydraulic actuator 8 is a double-stroke cylinder, fixedly installed on the bottom load-bearing beam of the main frame 4, and its piston rod is connected to the adjusting block 14. The adjusting block 14 is connected to the moving jaw plate mounting frame 7 through the thrust plate 12. The contact pressure detection element 18 is a thin-film pressure measuring device installed on the side of the moving jaw plate mounting frame 7 near the moving jaw plate 6. The signal cable of the thin-film pressure measuring device is led out from the reserved wire hole on the side wall of the main frame 1 and connected to the external electrical control device for real-time monitoring of the pressure of the moving jaw plate 6 on the moving jaw plate mounting frame 7, that is, the pressure P in the crushing chamber.

[0035] Specifically, the thrust plate 12 is inclinedly disposed between the moving jaw plate mounting frame 7 and the adjusting block 14, and is used in conjunction with the slots on the moving jaw plate mounting frame 7 and the adjusting block 14.

[0036] Specifically, the adjusting block 14 is movably mounted between the guide steel column 19 and the guide steel plate 20 on the main frame 4, and is used to guide the movement of the adjusting block 14 through the guide steel column 19 and the guide steel plate 20 to ensure smooth movement. Furthermore, a rubber buffer pad 15 is provided between the adjusting block 14 and the rear side wall of the main frame 4 to avoid direct contact between the adjusting block 14 and the rear side wall of the main frame 4 during adjustment, ensuring safe use.

[0037] Specifically, the gap adaptive mechanism also includes a linkage push rod 13, which is movably installed between the moving jaw plate mounting bracket 7 and the rear side wall of the main frame 4, and extends to the outside of the rear side wall. A spring 17 is sleeved on the part of the linkage push rod 13 that extends to the outside of the rear side wall. The other end of the spring 17 contacts a tightening nut 16, which is threadedly connected to the linkage push rod 13 to apply prestress to the spring 17. When the moving jaw plate 6 is in the standard working position, the spring 17 is in a stretched state.

[0038] During use, the contact pressure detection element 18 continuously collects the force data on the back of the moving jaw plate 6. When the detected value P exceeds the preset critical value, the external electrical control device determines that there is a hard object such as steel bar stuck, and then initiates the emergency procedure: First, a command is sent to the hydraulic actuator 8. The hydraulic oil is pressurized by the gear oil pump and flows into the rod chamber of the hydraulic actuator 8. The piston rod retracts, pushing the adjusting block 14 to move backward. Under the contraction force of the spring 17 restoring its deformation, the moving jaw plate 6 moves away from the stationary jaw component 5, the crushing area space expands, and the material compression state is released. After the material falls and the hard object stuck state is released, and after the value fed back by the contact pressure detection element 18 returns to the normal range, the external electrical control device sends a reset command. The hydraulic oil flows into the rodless chamber of the hydraulic actuator 8, the piston rod extends, and the moving jaw plate 6 returns to the standard working position.

[0039] It should be noted that the external electrical control device is a PID controller, which is a well-known prior art and will not be described in detail here.

[0040] The usage process of this smart construction site waste treatment equipment is as follows: Construction waste enters the crushing area from the top inlet. The drive motor 1 drives the eccentric shaft 10 to rotate, causing the moving jaw plate 6 to reciprocate periodically, performing crushing operations. The contact pressure detection element 18 continuously collects the force data on the back of the moving jaw plate 6. When the detected value P exceeds the preset critical value, the external electrical control device determines that there is a hard object such as steel bar stuck, and then initiates the emergency procedure: First, a command is sent to the hydraulic actuator 8. The hydraulic oil is pressurized by the gear oil pump and flows into the rod chamber of the hydraulic actuator 8. The piston rod retracts, pushing the adjusting block 14 to move backward. Under the contraction force of the spring 17 restoring its deformation, the moving jaw plate 6 moves away from the stationary jaw component 5, the crushing area space expands, and the material crushing state is released. After the material falls and the hard object is released, and after the value fed back by the contact pressure detection element 18 returns to the normal range, the external electrical control device sends a reset command. The hydraulic oil flows into the rodless chamber of the hydraulic actuator 8, the piston rod extends, and the moving jaw plate 6 returns to the standard working position.

[0041] This device integrates a mechanical linkage structure with a sensor feedback mechanism to achieve dynamic adaptation of the crushing gap and autonomous discharge of foreign objects, eliminating the need for manual intervention to clear obstructions, extending the service life of core components, and increasing the effective operating time per unit time.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
