Description

Technical Field

[0001] This utility model relates to the field of recycled concrete technology, specifically to a collaborative construction device for recycled concrete. Background Technology

[0002] With the rapid development of the construction industry, the resource utilization of construction waste, especially the recycling of waste concrete, has become an important way to achieve sustainable development. Recycled aggregate, as a material obtained from waste concrete through crushing and washing, directly affects the quality of recycled concrete. Grading is a key step in the production process of recycled aggregate. Its purpose is to separate aggregates according to particle size range to meet the mix proportion requirements of different grades of concrete. Then, the two stages of recycled aggregate processing and concrete production are seamlessly connected, completing the transformation from "construction waste" to "qualified recycled concrete" directly at or near the construction site, thereby achieving the goals of efficient, energy-saving, environmentally friendly, and high-quality construction.

[0003] However, the most common method used in the industry for grading recycled concrete blocks after crushing and washing is vibrating screening. This method relies on a vibrating motor to allow aggregate particles smaller than the screen apertures to pass through the screen, thus achieving grading. However, in this vibration mode, the screen lacks significant movement, which over time can prevent subsequent concrete blocks from being screened, reducing screening efficiency. To address these issues, the inventors propose a recycled concrete co-construction device. Utility Model Content

[0004] To address the problem that a lack of significant screen movement can cause particles larger than the screen aperture to clog the screen holes, preventing subsequent concrete blocks from being screened, this invention aims to provide a recycled concrete collaborative construction device.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a recycled concrete collaborative construction device, including a screening box, a collection box placed inside the screening box, a U-shaped frame slidably arranged inside the screening box, a screen frame slidably arranged inside the U-shaped frame, an installation plate fixedly arranged on one side of the screening box, a housing fixedly arranged on the top surface of the installation plate, a motor installed inside the housing, a worm gear fixedly arranged at the output end of the motor, a rotating shaft rotatably passing through the housing, a worm wheel fixedly sleeved on the outer surface of the rotating shaft, the worm gear meshing with the worm wheel, turntables fixedly arranged at both ends of the rotating shaft, a fixing rod fixedly arranged at one end of the turntable, a guide rod rotatably sleeved on the outer surface of the fixing rod, the guide rod hinged to... On one side of the U-shaped frame, the crushed and washed recycled aggregate is first poured into the screening box. Then, the motor is turned on, which causes the worm to rotate. The worm drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate. This causes the rotating shaft to rotate, and the two sets of rotating disks on both sides of the rotating shaft to rotate. The two sets of rotating disks drive the fixed rod to rotate, causing one end of the guide rod to rotate and fit onto one end of the fixed rod. The other end of the guide rod is hinged to one side of the U-shaped frame located above the screening box. (There are two sets of U-shaped frames and screen frames. The diameter of the screen holes in the upper screen frame is larger than that in the lower screen frame, and the two sets of U-shaped frames are fixedly connected by a connecting block.) This causes the two sets of U-shaped frames to move back and forth, and drives the two sets of screen frames to move back and forth, so that particles larger than the screen hole size can roll inside the screen frame and avoid clogging the screen holes.

[0006] Move the movable plate so that it slides into the limiting groove and squeeze the spring, thereby causing the stop block to disengage from the sliding plate. This causes the screen frame to move the sliding plate out of the U-shaped frame, allowing the two sets of screen frames to be disassembled. At the same time, the collection box can be pulled out from the screening box, allowing the different concrete blocks screened out to be collected and processed. Then, the collection box is placed back into the screening box, and the screen frame is slid into the U-shaped frame. Then, the movable plate is released, causing the spring to reset and the stop block to block one side of the sliding plate again, thus facilitating the subsequent screening of recycled aggregate.

[0007] Preferably, a fixing plate is fixedly provided on both sides of the U-shaped frame, a groove is provided in the sieve box, the fixing plate is slidably provided in the groove, an ear plate is fixedly provided on one side of the sieve box, and the rotating shaft rotates through the ear plate.

[0008] Preferably, the screen frame is fixedly provided with sliding plates on both sides, the sliding plates are slidably disposed within the U-shaped frame, the U-shaped frame has a sliding groove, the sliding plates are slidably disposed within the sliding groove, the U-shaped frame has a slidably provided stop block, the stop block can fit against one side of the sliding plate, the stop block has a fixedly provided moving plate on one side, the moving plate is slidably disposed within the U-shaped frame, the U-shaped frame has a limiting groove, the moving plate is slidably disposed within the limiting groove, and a spring is fixedly connected between the limiting groove and the moving plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. One end of the guide rod rotates and is sleeved on one end of the fixed rod, while the other end is hinged to one side of the U-shaped frame located above the screening box. This causes the two sets of U-shaped frames to move back and forth, which in turn drives the two sets of screen frames to move back and forth. This allows particles larger than the screen hole size to roll inside the screen frame, preventing clogging of the screen holes and improving screening efficiency.

[0011] 2. By moving the movable plate, it slides into the limiting groove and squeezes the spring, thereby causing the stop block to disengage from the sliding plate, which in turn causes the screen frame to move the sliding plate out of the U-shaped frame. This allows the two sets of screen frames to be disassembled, and the collection box to be pulled out of the screening box, so that the different concrete blocks screened out can be collected and processed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-7 As shown, this utility model provides a recycled concrete collaborative construction equipment, including a screening box 1, a collection box 11 placed inside the screening box 1, a U-shaped frame 3 slidably arranged inside the screening box 1, a screen frame 32 slidably arranged inside the U-shaped frame 3, an installation plate 2 fixedly arranged on one side of the screening box 1, a housing 21 fixedly arranged on the top surface of the installation plate 2, a motor 22 installed inside the housing 21, a worm gear 23 fixedly arranged at the output end of the motor 22, a rotating shaft 24 rotatably passing through the housing 21, a worm wheel 26 fixedly sleeved on the outer surface of the rotating shaft 24, the worm gear 23 meshing with the worm wheel 26, turntables 27 fixedly arranged at both ends of the rotating shaft 24, a fixing rod 28 fixedly arranged at one end of the turntable 27, a guide rod 29 rotatably sleeved on the outer surface of the fixing rod 28, the guide rod 29 hinged to one side of the U-shaped frame 3, and through... When motor 22 is turned on, worm gear 23 rotates, which drives worm wheel 26 to rotate. Worm wheel 26 drives shaft 24 to rotate, which in turn drives turntables 27 on both sides of shaft 24 to rotate. The two turntables 27 drive fixed rod 28 to rotate, causing one end of guide rod 29 to rotate and fit onto one end of fixed rod 28. The other end of guide rod 29 is hinged to one side of U-shaped frame 3 located above the screening box 1. (There are two sets of U-shaped frames 3 and screen frames 32. The diameter of the screen holes in the upper screen frame 32 is larger than that in the lower screen frame 32, and the two sets of U-shaped frames 3 are fixedly connected by connecting blocks.) This causes the two sets of U-shaped frames 3 to move back and forth, and drives the two sets of screen frames 32 to move back and forth. This allows particles larger than the screen hole size to roll inside the screen frame 32, avoiding clogging of the screen holes and improving screening efficiency.

[0023] The U-shaped frame 3 is fixedly provided with fixing plates 31 on both sides. The screening box 1 is provided with a groove 101. The fixing plate 31 is slidably provided in the groove 101. The screening box 1 is fixedly provided with an ear plate 25 on one side. The rotating shaft 24 rotates through the ear plate 25.

[0024] By adopting the above technical solution, the U-shaped frame 3 can drive the fixed plate 31 to slide in the groove 101 when it slides, thus playing an auxiliary sliding role. The ear plate 25 can be set so that the rotating shaft 24 can rotate in the ear plate 25, thereby supporting and limiting the rotating shaft 24.

[0025] Slide plates 33 are fixedly provided on both sides of the screen frame 32. The slide plates 33 are slidably disposed in the U-shaped frame 3. A sliding groove 301 is provided in the U-shaped frame 3. The slide plates 33 are slidably disposed in the sliding groove 301. A stop block 35 is slidably disposed in the U-shaped frame 3. The stop block 35 can fit against one side of the slide plate 33. A movable plate 34 is fixedly provided on one side of the stop block 35. The movable plate 34 is slidably disposed in the U-shaped frame 3. A limiting groove 302 is provided in the U-shaped frame 3. The movable plate 34 is slidably disposed in the limiting groove 302. A spring 36 is fixedly connected between the limiting groove 302 and the movable plate 34.

[0026] By adopting the above technical solution, by moving the movable plate 34, it slides within the limiting groove 302 and compresses the spring 36, thereby causing the stop block 35 to disengage from the slide plate 33, which in turn causes the screen frame 32 to move the slide plate 33 out of the U-shaped frame 3, thus enabling the two sets of screen frames 32 to be disassembled, and the collection box 11 to be pulled out from the screening box 1, thereby enabling the collection and processing of different concrete blocks screened out.

[0027] Working principle: First, the crushed and cleaned recycled aggregate is poured into the screening box 1. Then, the motor 22 is turned on, which causes the worm gear 23 to rotate. The worm gear 23 drives the worm wheel 26 to rotate, which in turn drives the rotating shaft 24 to rotate. This causes the rotating disks 27 on both sides of the rotating shaft 24 to rotate. The two sets of rotating disks 27 drive the fixed rod 28 to rotate, causing one end of the guide rod 29 to rotate and fit onto one end of the fixed rod 28. The other end of the guide rod 29 is hinged to one side of the U-shaped frame 3 located above the screening box 1. (There are two sets of U-shaped frames 3 and screen frames 32. The diameter of the screen holes in the upper screen frame 32 is larger than that in the lower screen frame 32, and the two sets of U-shaped frames 3 are fixedly connected by connecting blocks.) This causes the two sets of U-shaped frames 3 to move back and forth, and drives the two sets of screen frames 32 to move back and forth, so that particles larger than the screen hole size can roll inside the screen frame 32, avoiding clogging of the screen holes.

[0028] Move the movable plate 34 so that it slides into the limiting groove 302 and squeezes the spring 36, thereby causing the stop block 35 to disengage from the slide plate 33. This causes the screen frame 32 to move the slide plate 33 out of the U-shaped frame 3, allowing the two sets of screen frames 32 to be disassembled. At the same time, the collection box 11 is pulled out from the screening box 1, allowing the different concrete blocks screened out to be collected and processed. Then, the collection box 11 is placed back into the screening box 1, and the screen frame 32 is slid into the U-shaped frame 3. Then, the movable plate 34 is released, causing the spring 36 to return to its original position, so that the stop block 35 blocks one side of the slide plate 33 again, which facilitates the subsequent screening of recycled aggregate.

[0029] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
