Description

Technical Field

[0001] This utility model belongs to the field of construction waste recycling technology, specifically relating to a construction waste crushing and reuse equipment. Background Technology

[0002] With the rapid development of urban construction, a large amount of construction waste is generated during construction and demolition. This construction waste not only occupies land resources but also easily causes environmental pollution. In order to achieve resource recycling, the recycling and reuse of construction waste has become a key focus of the industry. Existing construction waste disposal methods mainly involve centralized transportation followed by landfill or simple crushing, which fails to fully realize the reuse value of resources.

[0003] Most construction waste crushing equipment currently on the market adopts a single jaw crusher structure, which crushes construction waste through the clamping and squeezing between a set of fixed jaw plates and a moving jaw plate. However, in practical applications, a single jaw crusher has the following main shortcomings: 1. Severe machine body vibration: During the eccentric movement of the single-acting jaw plate, significant vibration of the entire crusher body is caused. Long-term operation can easily lead to loosening, fatigue, or even damage of structural components, affecting the service life and stability of the equipment.

[0004] 2. Limited crushing efficiency: Under single-machine operation, the amount of construction waste that can be processed is limited due to structural and power limitations, making it difficult to meet the actual needs of large-scale and efficient processing of construction waste.

[0005] 3. Vibration affects the environment and safety: When equipment operates under vibration, it not only has an adverse impact on the operating environment, but may also cause instability in the equipment foundation, increasing safety hazards. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a construction waste crushing and recycling equipment, which improves the efficiency of construction waste processing, effectively eliminates the machine vibration generated during the crushing process, extends the service life of the equipment, and achieves higher crushing capacity.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A construction waste crushing and recycling device includes a jaw crusher A and a jaw crusher B. The jaw crushers A and B are connected with their tail ends aligned, and an integrated side plate is installed between the front and rear sides of the jaw crushers A and B by screws. A base is installed at the bottom of the jaw crushers A and B. The tail-end aligned connection method offsets the vibration generated during the use of the jaw crushers A and B. The jaw crushers A and B are controlled by the same starter.

[0008] Furthermore, an inverted V-shaped bracket is installed between the two integrated side plates by screws, and a V-shaped support rod is also installed through the inverted V-shaped bracket and the integrated side plate, the V-shaped support rod being used to support the inverted V-shaped bracket.

[0009] Furthermore, the interior of the inverted V-shaped bracket is uniformly welded with reinforcing plates, which are used to enhance the mechanical strength of the inverted V-shaped bracket.

[0010] Furthermore, a movable jaw plate is bolted to one side of the jaw crusher A, and a movable jaw plate is bolted to one side of the jaw crusher B. Fixed jaw plates are installed on both sides of the inverted V-shaped bracket, and the fixed jaw plates and movable jaw plates correspond one-to-one.

[0011] Furthermore, a triangular iron is installed between the jaw crusher A and the base, and a triangular iron is also installed between the jaw crusher B and the base.

[0012] Furthermore, the base is provided with a discharge port below the fixed jaw plate.

[0013] Furthermore, a triangular iron is also installed between the integrated side plate and the base, and the integrated side plate and the base are connected and fixed by the triangular iron.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This equipment adopts a structure with two jaw crushers installed with their tail ends aligned, combined with an integrated side plate and a multi-point fixing method, which effectively counteracts the vibration generated when a single jaw crusher is working. This greatly reduces the risk of structural fatigue and damage caused by machine body shaking, improves the stability of the overall structure and the service life of the equipment, and solves the problems of severe vibration and easy damage of components in existing single crushers.

[0015] By using the bidirectional impact and extrusion of the moving jaw plate and the fixed jaw plate, synchronous crushing and efficient material processing are achieved, which greatly increases the amount of construction waste processed per unit time, meets the needs of efficient resource recycling of large-scale construction waste, and overcomes the problem of limited efficiency of traditional single-machine crushing.

[0016] The base, triangular iron, inverted V-shaped bracket, and integrated side plate are among the multiple structural reinforcement measures that work together to ensure that the equipment maintains good mechanical strength and impact resistance during high-intensity, long-term continuous operation, significantly improving safety and reliability and solving the industry challenge of vibration affecting equipment foundation and operational safety.

[0017] The control system enables the synchronous start-up and operation of the two jaw crushers, ensuring a high degree of consistency in crushing actions, effectively preventing uneven crushing and material accumulation, further improving the continuity of operations and processing efficiency, and optimizing the on-site operating experience and the level of equipment intelligence.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0021] like Figure 1 As shown, a construction waste crushing and recycling equipment includes a jaw crusher A101 and a jaw crusher B102. The tail ends of jaw crushers A101 and B102 are aligned and connected, ensuring overall structural stability and preventing misalignment due to vibration during operation. An integrated side plate 104 is screwed between the front and rear sides of jaw crushers A101 and B102, providing lateral connection and support for the two jaw crushers and preventing lateral displacement during high-intensity crushing operations. The bottoms of both jaw crushers A101 and B102 are... A base 105 is installed to support the overall weight of the equipment, ensuring stable operation during crushing. The tail-end aligned connection method offsets the vibration generated during the use of jaw crushers A101 and B102. This structure combines the principle of dual-machine offsetting, significantly reducing machine vibration and improving equipment stability and service life. Jaw crushers A101 and B102 are started by the same starter. Synchronized start control ensures that the moving jaw plates 108 of the two jaw crushers move in tandem, thereby improving the crushing efficiency and processing capacity of construction waste.

[0022] like Figure 1 and Figure 2As shown, an inverted V-shaped bracket 103 is installed between the two integrated side plates 104 by screws. The inverted V-shaped bracket 103, as one of the main load-bearing structures of the equipment, can effectively distribute and transfer the load during equipment operation. A V-shaped support rod 106 is also installed between the inverted V-shaped bracket 103 and the integrated side plate 104. The V-shaped support rod 106 is connected to the integrated side plate 104 by bolts, which can strengthen the overall rigidity of the structure, effectively prevent the bracket from loosening due to high-frequency vibration, and ensure the long-term stable operation of the equipment. The V-shaped support rod 106 also provides longitudinal fixation and support for the inverted V-shaped bracket 103, further improving the mechanical strength of the equipment.

[0023] like Figure 3 As shown, the inverted V-shaped bracket 103 has reinforcing plates 132 uniformly welded inside. The reinforcing plates 132 are distributed in the stress area of ​​the inverted V-shaped bracket 103 by multiple welding points, which can significantly improve the mechanical strength of the inverted V-shaped bracket 103, prevent deformation or breakage under heavy load or long-term operation, and ensure the overall safety and reliability of the equipment structure.

[0024] like Figure 1 and Figure 2 As shown, a movable jaw plate 108 is bolted to one side of the jaw crusher A101. Driven by an eccentric motor, the movable jaw plate 108 can reciprocate and squeeze the fixed jaw plate 131 to achieve efficient crushing of construction waste. A movable jaw plate 108 is also bolted to one side of the jaw crusher B102. The synchronous movement of the movable jaw plates 108 of the two jaw crushers can perform bidirectional impact and squeezing on the input construction waste, improving crushing efficiency. Fixed jaw plates 131 are installed on both sides of the inverted V-shaped support 103. The fixed jaw plates 131 correspond one-to-one with the movable jaw plates 108 to form the main crushing channel for construction waste, ensuring that the waste is fully crushed under uniform force and improving the resource reuse rate.

[0025] like Figure 1 As shown, a triangular iron 107 is installed between the jaw crusher A101 and the base 105. The triangular iron 107 is tightly connected to the base 105 by welding and bolting, which can provide additional vertical support for the jaw crusher A101, enhance the load-bearing capacity of the equipment during operation, and reduce machine vibration. A triangular iron 107 is also installed between the jaw crusher B102 and the base 105, which also plays the role of stabilizing the equipment structure and improving the vibration resistance, preventing the base from loosening or the structure from deforming due to long-term operation.

[0026] like Figure 1 As shown, the base 105 is provided with a discharge port below the fixed jaw plate 131. The discharge port is used to discharge the construction waste particles after they have been fully crushed by the moving jaw plate 108 and the fixed jaw plate 131 in an orderly manner, which facilitates subsequent collection and reuse. At the same time, it avoids the accumulation and blockage of materials in the crushing chamber, thereby improving the working efficiency and continuous operation capability of the equipment.

[0027] like Figure 1 As shown, a triangular iron 107 is also installed between the integrated side plate 104 and the base 105. The triangular iron 107 can effectively enhance the connection strength between the integrated side plate 104 and the base 105, improve the overall structure and impact resistance of the machine, and ensure the safety and stability of the equipment in high-intensity and long-term crushing operations. The integrated side plate 104 and the base 105 are connected and fixed by the triangular iron 107 to form a sturdy frame structure, which further suppresses vibration during operation and extends the service life of the equipment. Example

[0028] See Figures 1-3 The specific application of a construction waste crushing and recycling equipment is as follows: In this embodiment, the construction waste crushing and recycling equipment includes two symmetrically arranged jaw crushers, A101 and B102. The two jaw crushers are mounted on the same base 105 with their tail ends aligned. The entire unit is securely connected to the base 105 using screws and welding. The base 105 is made of high-strength wear-resistant steel plate, capable of withstanding long-term heavy-load operation. Integrated side plates 104 are installed on both sides of the equipment. These integrated side plates 104 are integrally stamped to ensure the stability of the lateral connection. An inverted V-shaped bracket 103 is connected to the rear of the equipment via screws. The inverted V-shaped bracket 103 is made of thick-walled steel, with its bottom ends connected to the integrated side plates 104 via V-shaped support rods 106. Reinforcing nuts are provided at both ends of the V-shaped support rods 106 to prevent loosening during operation. Multiple reinforcing plates 132 are uniformly welded inside the inverted V-shaped bracket 103. The number of reinforcing plates 132 matches the stress analysis, ensuring the overall rigidity of the bracket.

[0029] During operation, the conveyor's discharge port is installed on top of the equipment and aligned directly above the fixed jaw plate 131. The conveyor adopts a belt structure, and the feeding speed can be adjusted according to actual needs. Construction waste is continuously and evenly fed into the space between the fixed jaw plate 131 and the movable jaw plate 108 via the conveyor. The fixed jaw plate 131 is fixed on both sides of the inverted V-shaped bracket 103 using multi-point bolt connections, capable of withstanding the periodic impacts from the movable jaw plate 108. The movable jaw plate 108 is driven by an eccentric motor, which is installed inside the jaw crusher A101 and jaw crusher B102. The power output shaft is connected to the movable jaw plate 108 via a connecting rod, realizing the reciprocating linear motion of the movable jaw plate 108. To further improve the stability of power transmission, a rolling bearing assembly is installed between the movable jaw plate 108 and the connecting rod. The rolling bearing assembly adopts a high-precision sealing structure to extend its service life.

[0030] The control system of this equipment is managed by a unified intelligent starter. The intelligent starter uses a PLC module for control and allows parameter setting and start / stop operations via a touch screen. The starter is connected to the power lines of two jaw crushers simultaneously, ensuring that the two moving jaw plates 108 can start and stop synchronously, effectively preventing uneven crushing or machine shaking caused by asynchronous power. During operation, the construction waste is squeezed between the two moving jaw plates 108, which alternately crush the construction waste. Due to the dual-machine counter-impact structure, the overall vibration of the equipment is greatly reduced. The base 105 and the triangular iron 107 work together to support the machine body, effectively improving structural stability.

[0031] The crushed material is discharged in an orderly manner from the outlet below the fixed jaw plate 131. The outlet adopts a graded grid structure, which can perform preliminary screening of the crushed material. Large pieces of material flow back to the crushing zone for further crushing, while fine particles fall directly into the collection device. The collection device is located below the base 105, is made of high-strength steel, and is equipped with a buffer pad to prevent damage to the equipment from the impact generated during secondary crushing. The equipment adopts a modular design, and the main components are fixed together by high-strength bolts and welding, which facilitates later disassembly and maintenance.

[0032] The working principle of this utility model is as follows: First, the construction waste is evenly transported to the top of the equipment by the conveyor, and the discharge port of the conveyor is aligned with the top of the fixed jaw plate 131 to ensure that the construction waste can smoothly enter the crushing area of ​​jaw crusher A101 and jaw crusher B102. Construction waste falls from the discharge port into the space between the fixed jaw plate 131 and the movable jaw plate 108. The fixed jaw plate 131 is installed on the left and right sides of the inverted V-shaped bracket 103 and is fixedly connected to the inverted V-shaped bracket 103 by multiple bolts to form a stable crushing channel. After the control system is started, the starter simultaneously activates the power systems of jaw crusher A101 and jaw crusher B102. The moving jaw plates 108 of the two jaw crushers achieve synchronous reciprocating linear motion under the drive of the eccentric motor. The moving jaw plates 108 are connected to the eccentric wheel inside the machine body through the connecting rod assembly. The rolling bearing assembly is used to reduce friction and improve transmission efficiency, ensuring the stability and accuracy of the movement of the moving jaw plates 108. Under the clamping of the moving jaw plate 108 and the fixed jaw plate 131, the construction waste is subjected to continuous bidirectional impact extrusion force and is gradually crushed into small particles; the dual-machine impact structure effectively offsets the vibration during the crushing process; the integrated side plate 104 and the inverted V-shaped bracket 103 are reinforced by screws and V-shaped bracket support rods 106 to improve the overall rigidity and stability of the equipment. The crushed material is discharged through the discharge port below the fixed jaw plate 131. The discharge port is set at the corresponding position of the base 105 to facilitate the orderly collection and transfer of crushed particles. The collection device is installed below the base 105 and adopts a high-strength steel plate and buffer pad structure to reduce the impact of secondary impact on the equipment. The base 105 is reinforced and connected to the jaw crusher A101 and jaw crusher B102 by a triangular iron 107. The triangular iron 107 is also used to fix the integrated side plate 104 and the base 105 to ensure that the equipment will not loosen or deform during continuous operation. The inverted V-shaped bracket 103 has reinforcing plates 132 welded evenly inside. The reinforcing plates 132 improve the overall strength and load-bearing capacity of the bracket, ensuring that the equipment remains stable and safe under high load operation. The overall structure adopts a modular design. All key components (including jaw crusher A101, jaw crusher B102, base 105, integrated side plate 104, inverted V-shaped bracket 103, V-shaped frame support rod 106, triangular iron 107, moving jaw plate 108, fixed jaw plate 131, reinforcing plate 132, etc.) are fixed by screws or welding, which facilitates disassembly and maintenance and ensures long-term, efficient and safe operation of the equipment.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
