Description

Technical Field

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

[0002] Aggregates are used in infrastructure construction such as road and bridge construction, and the uniformity of these aggregates often determines the quality of the project. Therefore, how to produce products with uniform particle size from construction waste has become a key focus of research and development.

[0003] Chinese Patent No. CN222132031U discloses a crushing device for construction waste stone, including a crushing box, a first motor, a screening device, and a vibrating device. A rotating drum is mounted on the inner wall of the crushing box via a connecting shaft, and multiple material distribution plates are welded at equal angles to the outer wall of the rotating drum. This crushing device, with a vibrating device installed at the bottom of the crushing box, allows a second motor in the vibrating device to drive a cam to rotate via a drive shaft. This causes the right end of the first screen plate to vibrate vertically. The vibration of the first screen plate, through a connecting rod, drives the vibration of the second screen plate. The crushed stone falls onto the first screen plate, with larger stones being intercepted on its surface, while smaller stones fall through the discharge holes into the second screen plate for further screening. Thus, the crushed stone can be screened into different sizes during the discharge process, improving the stone classification efficiency.

[0004] However, the above technical solutions have the following shortcomings: construction waste often contains a certain amount of steel bars and other debris. If the steel bars and other metal debris are not removed during crushing, the metal debris will further corrode the quality of the aggregate during the oxidation process, thus leading to a decline in the overall quality of the aggregate. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a construction waste stone crushing device that uses an electromagnetic suction plate to attract crushed stone containing iron products and discards the crushed stone when the electromagnetic suction plate moves to the outside of the frame, thereby avoiding the impact of iron products on the quality of aggregates.

[0006] The technical solution of this utility model is a crushing device for construction waste stone, comprising: a frame, which is provided with a crushing component, a filter plate and a conveying component from top to bottom; a screening component, which is provided with two sets opposite each other on the frame, the screening component including a rotating rod on the frame, a plurality of electromagnetic suction plates arranged in a ring on the rotating rod, a plurality of supporting ribs between the plurality of electromagnetic suction plates, a grounding block slidably arranged on the electromagnetic suction plates, a spring arranged between the plurality of grounding blocks and the plurality of electromagnetic suction plates, a grounding frame on the frame, and a grounding half-ring arranged on the grounding frame; the frame, grounding frame, grounding half-ring, grounding block, spring and electromagnetic suction plate are electrically connected in sequence; and a drive component, which is drivenly connected to the screening component and the crushing component.

[0007] Preferably, both the contact block and the contact half-ring are made of metal, and the hardness of the contact block is less than that of the contact half-ring.

[0008] Preferably, the crushing assembly includes two crushing rollers that are rotatably mounted on a frame.

[0009] Preferably, the drive assembly includes a motor mounted on the frame, a sprocket a mounted on each of the two rotating rods, a gear a and a sprocket b mounted on each of the two crushing rollers, and a chain mounted on each of the two sprockets a and the two sprockets b; the motor is driven by the rotating rods, and the two gears a are meshed with each other.

[0010] Preferably, the frame is further provided with a reset assembly, which includes a plurality of clamping cylinders arranged in a ring on the frame, a reset ring rotatably arranged on the plurality of clamping cylinders, a motor a arranged on the frame, a gear b arranged at the output end of the motor a, and a guide frame arranged on the frame; the reset ring has a gear part, which meshes with the gear b.

[0011] Preferably, the inner circumferential surface of the reset ring has a storage trough distributed along the ring, and the reset ring also has a plurality of partition plates evenly distributed along the ring, with the plurality of partition plates distributed at the storage trough.

[0012] Compared with the prior art, this utility model has the following beneficial technical effects: When processing crushed stone, the iron screening component is located above the crushing component, and the electromagnetic suction plate generates magnetic adsorption of ferrous crushed stone through electrical connection, preventing it from affecting the quality of aggregate. When crushing stone for the first time, the stone is relatively large, and the iron screening component is located between the crushing component and the filter plate, performing the same operation to ensure the quality of aggregate.

[0013] After passing through the filter plate, the aggregate is output by the conveying assembly; the filter plate is equipped with a vibrating component and is placed at an angle to guide the aggregate into the storage trough. The separator supports the aggregate, ensuring that it falls onto the guide frame, where the stone is further crushed under gravity until it meets the requirements, thus improving the aggregate quality.

[0019] Example 1

[0020] like Figures 1-4 As shown, the construction waste stone crushing device proposed in this embodiment includes a frame 1, a screen assembly 2, and a drive assembly. The frame 1 is arranged from top to bottom with a crushing assembly, a filter plate 7, and a conveying assembly 11. Two sets of screen assemblies 2 are arranged opposite each other on the frame 1. The screen assembly 2 includes a rotating rod 21 arranged on the frame 1, multiple electromagnetic suction plates 22 arranged in a ring on the rotating rod 21, multiple support ribs 23 arranged between the multiple electromagnetic suction plates 22, a grounding block 24 slidably arranged on the electromagnetic suction plate 22, a spring 27 arranged between the multiple grounding blocks 24 and the multiple electromagnetic suction plates 22, a grounding frame 26 arranged on the frame 1, and a grounding half-ring 25 arranged on the grounding frame 26. The frame 1, the grounding frame 26, the grounding half-ring 25, the grounding block 24, the spring, and the electromagnetic suction plate 22 are electrically connected in sequence. The drive assembly is drivenly connected to the screen assembly 2 and the crushing assembly.

[0021] Both the grounding block 24 and the grounding half-ring 25 are made of metal. The hardness of the grounding block 24 is less than that of the grounding half-ring 25. Therefore, during use, the wear rate of the grounding half-ring 25 is much less than that of the grounding block 24, allowing workers to simply replace the grounding block 24, thus reducing the difficulty of equipment maintenance.

[0022] In this embodiment, if the stone to be crushed is already crushed once and is smaller, the iron screening component 2 is positioned above the crushing component. When the electromagnetic suction plate 22 moves into the frame 1, the energized half-ring 25 and the energized block 24 are electrically connected, thereby generating magnetism in the electromagnetic suction plate 22. The electromagnetic suction plate 22 adsorbs and removes the crushed stone containing iron products, thus preventing iron products from remaining in the produced aggregate and affecting the aggregate quality. If the stone is being crushed for the first time, the iron screening component 2 is positioned between the crushing component and the filter plate 7, and the previous operation is repeated to ensure the quality of the aggregate crushed by the device. After the aggregate passes through the filter plate 7, the conveying component 11 conveys the aggregate out of the device.

[0023] Example 2

[0024] like Figures 1-3 As shown, this embodiment of the construction waste stone crushing device, compared to Embodiment 1, includes two crushing rollers 6 rotatably mounted on a frame 1 as the crushing component. The driving component includes a motor mounted on the frame 1, a sprocket a3 mounted on each of the two rotating rods, a gear a4 mounted on each of the two crushing rollers 6, and a chain mounted on each of the two sprockets a3 and the two sprockets b5; the motor is driven by the rotating rods, and the two gears a4 are meshed with each other.

[0025] In this embodiment, the motor drives one of the rotating rods to rotate, which in turn drives sprocket a3 to rotate. Sprocket a3 then drives sprocket b5, gear a4, gear a4, sprocket b5, chain, and sprocket a3 to rotate sequentially via a chain. The diameter difference between sprocket a3 and sprocket b5 can be adjusted according to the transmission ratio required by the user, thereby improving the operability of the equipment.

[0026] Example 3

[0027] like Figure 1 and Figure 2 As shown, the construction waste stone crushing device proposed in this embodiment, compared with the first embodiment, in this embodiment, the frame 1 is also provided with a reset assembly. The reset assembly includes a plurality of clamping cylinders arranged in a ring on the frame 1, a reset ring 8 rotatably arranged on the plurality of clamping cylinders, a motor a10 arranged on the frame 1, a gear b arranged at the output end of the motor a10, and a guide frame 9 arranged on the frame 1; the reset ring 8 has a gear part, and the gear part is meshed with the gear b.

[0028] The inner circumferential surface of the reset ring 8 has a storage trough distributed along the ring, and the reset ring 8 also has multiple partition plates evenly distributed along the ring, with the multiple partition plates distributed at the storage trough.

[0029] In this embodiment, a vibration assembly is connected to the filter plate 7, and the filter plate 7 is placed at an angle. The vibration assembly causes the aggregate that cannot pass through the filter plate 7 to fall into the storage tank along the inclined direction of the filter plate 7. Multiple partition plates support the aggregate when they are parallel to the ground, thereby ensuring that the aggregate can fall onto the guide frame 9. The stones that fall onto the guide frame 9 fall back onto the crushing assembly under their own weight for secondary crushing until the size of the aggregate meets the user's needs, thereby improving the production quality of the aggregate.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
