Description

Technical Field

[0001] This utility model relates to the field of gravel paving, specifically a gravel paving device for community environment construction. Background Technology

[0002] With the accelerating pace of urbanization, the creation and construction of community environments are receiving increasing attention. As an important component of the community environment, the quality and aesthetics of community roads directly impact residents' living experience.

[0003] After extensive searching, it was found that the existing technology disclosure number CN220704256U discloses an asphalt concrete pavement crushed stone laying device. The solution includes a device base, a crushing box, a material discharge box, and a storage box. The crushing box is fixedly connected to the device base, the material discharge box is fixedly connected to the crushing box and communicates with the crushing box, and the storage box is fixedly connected to the material discharge box and communicates with the material discharge box, so that the concrete crushed stone laying device can uniformly mix the concrete crushed stone before laying during use.

[0004] Therefore, based on the above-mentioned research and in combination with existing information, in actual road construction, the terrain and foundation conditions of different road sections may vary. Some places may require thicker paving to fill depressions and make the road surface smooth; while other places only require thinner paving. However, because the device cannot adjust the paving thickness, it cannot be adjusted according to the road surface conditions during use. This requires construction workers to spend more time and effort on manual adjustments or multiple reworks, which will undoubtedly reduce construction efficiency, prolong the construction cycle, and increase labor costs. Therefore, this utility model provides a crushed stone paving device for community environment construction to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gravel paving device for community environment construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a shell, the top of which is fixedly connected to a shaped shell for guiding stones; a discharge trough for stone outflow is provided at the end of the shell away from the shaped shell; a guide plate for assisting stone laying is fixedly connected to one side of the shell; a crushing rod for crushing stones is rotatably connected to the inner cavity of the shell; a partition for separating stones is fixedly connected to the inner cavity of the shell; a rotating shell for transporting stones is rotatably connected to the inner cavity of the partition, and the rotating shell ensures that the stones can move evenly to the other side of the discharge trough; and multiple sliding plates for adjusting the thickness of the crushed stone are slidably connected inside the discharge trough, and the range of crushed stone laying is adjusted by the sliding plates.

[0007] Furthermore, the inner cavity of the housing is rotatably connected to a rotating plate for pushing the sliding plate to slide, and the bottom of the rotating plate is fixedly connected to a shaped rod for pushing the sliding plate to move. The inner cavity of the sliding plate is provided with a strip-shaped limiting groove for providing the sliding of the shaped rod.

[0008] Furthermore, a secondary crushing rod is rotatably connected to one side of the crushing rod, and the crushing rod and the secondary crushing rod cooperate to crush the stone. A gear one for driving the crushing rod to rotate is rotatably connected to one side of the crushing rod, and a gear two for driving the secondary crushing rod to rotate is fixedly connected to the end of the secondary crushing rod near the gear one.

[0009] Furthermore, the inner cavity of the partition is rotatably connected to a rotating shaft for driving the rotating shell via a bearing, and the rotating shell is arranged in groups of four with three sets of outer walls fixed around the rotating shaft.

[0010] Furthermore, the inner cavity of the sliding plate is provided with a water spray nozzle for dust suppression of the stones, and the inner cavity of the water spray nozzle is provided with a circular groove for water flow. A water storage tank for water storage is fixedly connected to the top of the shell.

[0011] Furthermore, the bottom of the housing is rotatably connected to a roller for assisting the movement of the housing, and one side of the housing is fixedly connected to a block for traction of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting multiple sliding plates inside the discharge chute and adjusting the spacing between the sliding plates, the paving area is reduced when the sliding plates are close to each other, which can adapt to narrow paths, winding walkways and various irregular areas in the community, increase the paving thickness and increase the stability. Conversely, when the distance between the sliding plates is large, the paving area can be expanded, improving work efficiency and quickly completing the gravel paving work to meet the diverse needs of different roads.

[0014] 2. By opening water spray nozzles at both ends of the sliding plate, water is sprayed onto the surface of the stones as they flow out from both sides of the sliding plate. This makes it easier to control the spray range, avoids accidentally spraying workers, and reduces dust on the stones, thus reducing dust pollution to the community environment during the stone laying process.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figures 1-4 A gravel paving device for community environment construction includes a housing 1. A shaped shell 2, wider at the top and narrower at the bottom, is fixedly connected to the top of the housing 1 to guide the flow of stones. The shaped shell 2 is funnel-shaped, wider at the top and narrower at the bottom, to facilitate guiding the stones into the inner cavity of the housing 1. A discharge chute 6 for stone outflow is provided at the end of the housing 1 away from the shaped shell 2. A guide plate 601 for assisting stone paving is fixedly connected to one side of the housing 1, and the guide plate 601 is located on one side of the discharge chute 6 so that when the stones flow out through the discharge chute 6, they are laid on the ground by the guide plate 601. A crushing rod 3 is rotatably connected to the inner cavity of the housing 1 to crush the stones into uniform small pieces. A partition 4 for separating the stones is fixedly connected to the inner cavity of the housing 1. A rotating shell 5 for transporting stones is rotatably connected to the inner cavity of the partition 4. (See also...) Figure 2The inner cavity of the shell 1 is arc-shaped to facilitate the flow of stones towards the rotating shell 5. The rotating shell 5 ensures that the stones move evenly to the other side of the inner cavity of the discharge trough 6, thus preventing the stones from flowing too fast due to their weight and causing blockage inside the discharge trough 6. The interior of the discharge trough 6 is inclined so that the stones flow away from the irregular shell 2. Multiple sliding plates 7 are slidably connected inside the discharge trough 6 to adjust the thickness of the crushed stone and adjust the range of crushed stone laying. There are four arrays of sliding plates 7 in the inner cavity of the discharge trough 6 to ensure uniform laying. If the crushed stone becomes blocked during the laying process, the spacing of the sliding plates 7 can be adjusted to clear the blockage.

[0022] Please see Figures 2-3 The inner cavity of the housing 1 is rotatably connected to a rotating plate 701 for pushing the sliding plate 7 to slide. The rotating plate 701 pushes multiple sliding plates 7 to slide simultaneously to adjust the distance between the sliding plates 7. The bottom of the rotating plate 701 is fixedly connected to an irregularly shaped rod 702 for pushing the sliding plate 7 to move. The inner cavity of the sliding plate 7 is provided with a strip-shaped limiting groove 703 for providing sliding of the irregularly shaped rod 702. Specifically, the inner cavity of the housing 1 is provided with a square groove 705 for providing rotation of the rotating plate 701, and the rotating plate 701 is rotatably connected to the inner cavity of the square groove 705. The top of the housing 1 is fixedly installed with a motor 704 for driving the rotating plate 701 to rotate. The output shaft of the motor 704 passes through the housing 1 and is fixedly connected to the top of the rotating plate 701. The output shaft of the motor 704 drives the rotating plate 701 to rotate, so that the rotating plate 701 slides inside the strip-shaped limiting groove 703 through the shaped rod 702. This pulls the sliding plate 7 closer to the motor 704, so as to reduce the paving range, adapt to the internal roads of the community, increase the paving thickness, and increase the stability. Alternatively, the sliding plate 7 can be pushed to slide away from the motor 704, increasing the distance between the sliding plates 7, so as to expand the paving range, improve work efficiency, reduce the paving thickness, and meet the diverse needs of different roads.

[0023] More specifically, the inner cavity of the housing 1 is fixedly connected with a strip groove 705 for limiting the sliding plate 7. A sliding block 706 is slidably connected to the inner cavity of the strip groove 705, and the end of the sliding block 706 near the sliding plate 7 is fixedly connected to the sliding plate 7, so that the sliding plate 7 can only slide in the inner cavity of the housing 1, and avoids the sliding plate 7 from shaking during the sliding process.

[0024] A folding plate 707 for restricting the flow of stones is fixedly connected to the inner cavity of the housing 1. A sliding rod is fixedly connected to one side of the folding plate 707, and a transverse groove for providing sliding for the sliding rod is slidably connected to the inner cavity of the housing 1. The sliding rod slides inside the transverse groove to restrict the folding plate 707 and prevent the folding plate 707 from bending downwards when stones fall on top of it. The material of the folding plate 707 is relatively hard to prevent it from being damaged by stones, and the folding part of the folding plate 707 is relatively flexible to facilitate expansion and contraction. The folding plate 707 is fixedly connected to a sliding plate 7 away from the motor 704, so that when this sliding plate 7 slides, it prevents stones from flowing out through the gap between the sliding plate 7 and the discharge chute 6.

[0025] Example 2: Please refer to Figure 2 A crushed stone paving device for community environment construction differs from Embodiment 1 in that a secondary crushing rod 301 is rotatably connected to one side of the crushing rod 3, and the crushing rod 3 and the secondary crushing rod 301 cooperate to crush the stones. A gear 302 for driving the crushing rod 3 to rotate is rotatably connected to one side of the crushing rod 3. A gear 303 for driving the secondary crushing rod 301 to rotate is fixedly connected to the end of the secondary crushing rod 301 near the gear 302. Specifically, the ends of the crushing rod 3 and the secondary crushing rod 301 away from the gear 302 are rotatably connected to the housing 1 through bearings. A motor 304 for driving the gear 302 to rotate is fixedly connected to the outer wall of the housing 1. The motor 304 outputs... The output shaft passes through the housing 1 and is fixedly connected to gear 302. It can drive the output shaft of the motor 304 to drive gear 302 and the crushing rod 3 to rotate. At the same time, gear 302 drives gear 303 and the secondary crushing rod 301 to rotate, so that the crushing rod 3 and the secondary crushing rod 301 can crush the stones. The end of gear 303 near the motor 304 is rotatably connected to the inner cavity of the housing 1 through a bearing. The inner cavity of the housing 1 has a square groove for providing rotation for gear 302 and gear 303. Gear 302 and gear 303 are rotatably connected to the inner cavity of the square groove, thereby preventing damage to gear 302 and gear 303 when stones enter the interior of the housing 1.

[0026] Please see Figure 2The inner cavity of the partition 4 is rotatably connected to a rotating shaft 501 for driving the rotating shell 5 via a bearing. Three sets of rotating shells 5 are fixedly arranged around the outer wall of the rotating shaft 501, so that when the rotating shaft 501 rotates, the four rotating shells 5 alternately drive the stones to flow evenly to the discharge trough 6. The outer wall of the shell 1 is fixedly connected to a motor 502 for driving the rotating shaft 501 to rotate, and the output shaft of the motor 502 passes through the shell 1 and is fixedly connected to the rotating shaft 501. Thus, by driving the motor 502, its output shaft drives the rotating shaft 501 and the rotating shell 5 to rotate, so that the rotating shell 5 can continuously and evenly transport the stones, ensuring that the stones flow evenly to the discharge trough 6, thereby preventing the stones from accumulating inside the shell 1 and jamming the rotating shell 5, causing it to be unable to rotate.

[0027] Please see Figure 2 and Figure 4 The sliding plate 7 has a water spray nozzle 8 for dust suppression of the stones. The water spray nozzle 8 has a circular groove 801 for water flow. A water storage tank 802 is fixedly connected to the top of the housing 1. Specifically, a water transfer pipe 803 for water delivery is fixedly connected to one end of the water storage tank 802. A flexible hose 804 for connection is fixedly connected to the bottom of the transfer pipe 803. The housing 1 has an inner groove 805 for providing movement for the flexible hose 804. The flexible hose 804 is located in the inner cavity of the inner groove 805, so that when the flexible hose 804 extends and retracts with the sliding plate 7, it moves inside the inner groove 805. The bottom of the flexible hose 804 is fixedly connected to the top of the sliding plate 7 and corresponds to the position of the circular groove 801. Water from the water storage tank 802 enters the interior of the circular groove 801 through the transfer pipe 803 and the flexible hose 804, and is evenly sprayed out through the water spray nozzle 8, so as to suppress dust on the stones when they flow out through the discharge chute 6.

[0028] Please see Figures 1-2 The bottom of the housing 1 is rotatably connected to rollers 101 for assisting the movement of the housing 1. There are four rollers 101 arranged in an array at the bottom of the housing 1 to ensure the stability of the housing 1 when it moves. A block 102 for pulling the housing 1 is fixedly connected to one side of the housing 1. The inner cavity of the block 102 is provided with a through groove so that a pull rope can be inserted into the through groove and connected to other vehicles. Then, by moving the vehicle, the pull rope is used to pull the block 102 to drive the housing 1 to move.

[0029] Working principle: First, based on the community environment, adjust the drive motor 704 so that its output shaft drives the rotating plate 701 to rotate. The rotating plate 701 slides inside the strip-shaped limiting groove 703 via the irregular rod 702, thereby pulling the sliding plate 7 to slide and adjust the paving range and thickness. After adjustment, put the stones into the inner cavity of 2 into 1, and inject clean water into the water tank 802. Then, drive the drive motor 304 so that its output shaft drives the gear 1 302 and the compaction rod 3 to rotate. At the same time, the gear 1 302 pushes the gear 2 303 and the secondary compaction rod 301 to rotate. The rolling rod 3 and the secondary rolling rod 301 work together to crush the stones. The crushed stones can fall downwards by their own weight. Then, the output shaft of the drive motor 502 drives the rotating shaft 501 and the rotating shell 5 to rotate, so that the rotating shell 5 carries the stones to the end of the discharge chute 6. After the stones enter the interior of the discharge chute 6, the pull rope is inserted into the through chute and connected to other vehicles. Then, by moving the vehicles, the pull rope pulls the block 102 to move the shell 1. During the movement of the shell 1, the stones continuously flow out and are laid on the ground.

[0030] During the laying process, water from the water tank 802 enters the circular groove 801 through the connecting pipe 803 and the hose 804, and is evenly sprayed onto the surface of the stones through the spray nozzle 8 to reduce dust and minimize dust pollution to the community environment during the laying process.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
