Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gray line spraying technology, specifically relating to a gray line spraying device for municipal engineering. Background Technology
[0002] Lime line application is an important operation in road construction and municipal engineering. It involves using specific equipment or devices to evenly spread lime (such as quicklime or lime) onto a designated road surface to form lime lines or grid lines to guide subsequent construction work. It is widely used in the construction and maintenance of highways, urban roads, rural roads, squares, parking lots, and other locations. For lime line application operations in small areas or special environments, a handheld lime spreader is generally required. Existing handheld lime spreaders typically consist of a hopper, a discharge port, a handle, and wheels. Users pour the lime into the container. In the process of spreading ash, the amount of ash is adjusted by controlling the opening and closing of the ash outlet. During the spreading process, the user can hold the ash spreader and move it along the predetermined line. As the ash spreader moves, the ash flows out from the ash outlet and is spread evenly on the road surface. During the spreading of ash, because the ash is relatively light and needs to accumulate in the hopper for a long time, it is easy to clump in the storage container, which leads to poor material discharge and affects the spreading effect. Although the wheels will vibrate the ash in the hopper when they encounter bumpy roads during movement, on a continuously flat road surface, the vibration effect of the wheels is not achieved. Utility Model Content
[0003] To address the above problems, the purpose of this utility model is to provide a ash line spraying device for municipal engineering, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a ash line spraying device for municipal engineering, comprising a bearing for mounting a wheel and rotatably connected to the wheel, and a hopper mounted on one side of the wheel with its bottom extending to below the bearing. A mounting frame for mounting the hopper and detachably connected to the hopper is provided on the top of the bearing. A vibration component is provided between the mounting frame and the wheel. The rotation of the wheel drives the vibration component to strike the hopper, keeping the ash material loose within the container and ensuring even distribution. The vibration component includes a fixed shaft fixedly mounted on the top of the mounting frame with a striking plate rotatably connected to its outer side, a push plate mounted on the side of the wheel near the hopper for driving the striking plate to rotate along the fixed shaft to apply external force to the hopper, and an elastic element disposed between the fixed shaft and the striking plate for assisting the striking plate in resetting after striking the hopper.
[0005] The beneficial effects of this utility model are as follows: By using the vibration component, the power generated by the rotation of the wheel is used to drive the vibration component to work, eliminating the need for an additional power source, thus reducing energy consumption and cost. When the wheel rotates, it can drive the push plate to move, which in turn pushes the striking plate to rotate along the fixed axis, striking the hopper and keeping the ash material in a loose state in the hopper. This prevents the ash material from clumping due to long-term accumulation, thereby ensuring that the ash material can be fed evenly and improving construction quality and efficiency.
[0006] To avoid affecting the normal rotation of the wheels or applying too much force to the hopper, which could cause the hopper to deform:
[0007] As a further improvement to the above technical solution: the end of the striking plate away from the hopper is provided with a guide plate that cooperates with the push plate and facilitates the push plate to rotate away from the striking plate.
[0008] The beneficial effect of this improvement is that when the wheel rotates and drives the push plate to rotate past the guide plate, the free end of the push plate can slide along the curved surface of the guide plate, so as not to affect the normal rotation of the wheel or apply too much force to the hopper, which would cause the hopper to deform.
[0009] In order to reduce the impact force of the pusher plate on the hopper:
[0010] As a further improvement to the above technical solution: multiple elastic protrusions are evenly installed on the side of the striking plate near the hopper and facing the hopper.
[0011] The beneficial effects of this improvement are as follows: by setting multiple elastic protrusions on the striking plate, when the push plate strikes the hopper, the elastic action of the elastic protrusions can not only reduce the striking force of the striking plate on the hopper, but also assist the striking plate in resetting.
[0012] In order to increase the frequency at which the striking plate strikes the hopper:
[0013] As a further improvement to the above technical solution: the number of push plates is at least one, and the free end of the push plate extends to the connection between the guide plate and the push plate.
[0014] The beneficial effects of this improvement are: the number of push plates can be one or more. Multiple push plates are evenly distributed on the wheel, which can increase the frequency of the striking plates striking the hopper, so that the ash material in the hopper is always kept in a loose state, avoiding clumping and clogging of the hopper's discharge hopper.
[0015] In order to improve the vibration effect of the vibration component:
[0016] As a further improvement to the above technical solution: the number of vibration components is at least one set.
[0017] The beneficial effects of this improvement are as follows: when the number of vibration components is set to one, the vibration components can be set on one side of the hopper, that is, in the lower half of the hopper, close to the discharge port of the hopper. When the number of vibration components is two, they can be symmetrically distributed on both sides of the hopper, or distributed vertically on both sides of the hopper, thereby improving the vibration effect of the vibration components.
[0018] To avoid the vibration components affecting the installation and disassembly of the hopper:
[0019] As a further improvement to the above technical solution: when the wheel is not rotating, the end of the striking plate away from the wheel is in contact with the outer wall of the hopper.
[0020] The beneficial effects of this improvement are: when the wheel is not rotating, the push plate will not push the striking plate. At this time, the striking plate is in contact with the surface of the hopper but does not apply external force to the hopper. The elastic element between the striking plate and the fixed shaft is not affected by external force and will not affect the installation and disassembly of the hopper. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0028] The existing ash line spraying device of this utility model mainly consists of a hopper 3 with a material outlet at the bottom, a handle 12, and wheels 1. In use, the user pours ash into the hopper 3, closes the lid of the hopper 3, and then adjusts the amount of ash to be sprayed by controlling the opening and closing of the material outlet. During the ash spraying process, the user can hold the ash spreader and move it along the predetermined line. As the ash spreader moves, the ash flows out evenly from the material outlet and is spread on the road surface. The above is an introduction to the existing ash line spraying device.
[0029] As can be seen from the above, existing ash line spraying devices have the following drawbacks during use: due to the light weight of the ash material and its need to accumulate in the hopper 3 for a long time, it is prone to clumping in the storage container, leading to poor material discharge and affecting the spraying effect. Although the wheels 1 vibrate the ash material in the hopper 3 when encountering bumpy roads during movement, the vibration effect is insufficient on continuously flat roads. To solve the above problems, some ash line spraying devices have attempted to use vibration devices to prevent ash material from clumping, but these vibration devices often require an additional power source to drive them, increasing the complexity of the equipment and operating costs. Based on the above problems, this utility model adopts the following improvement method to solve them.
[0030] like Figure 1-5 As shown, a ash line spraying device for municipal engineering includes a bearing 2 for mounting a wheel 1 and rotatably connected to the wheel 1, and a hopper 3 mounted on one side of the wheel 1 with its bottom extending below the bearing 2. The top of the bearing 2 is provided with a mounting frame 4 for mounting the hopper 3 and detachably connected to the hopper 3. Figure 1 As shown, the mounting frame 4 is adapted to the outer contour of the hopper 3, and the inner side of the mounting frame 4 is provided with an internal thread. The outer wall of the hopper 3 is provided with an external thread adapted to the internal thread. The hopper 3 and the mounting frame 4 can be connected by threads. A vibration component is provided between the mounting frame 4 and the wheel 1. The rotation of the wheel 1 drives the vibration component to strike the hopper 3, keeping the ash material in a loose state in the container and enabling uniform feeding. The vibration component includes a fixed shaft 6 fixedly installed on the top of the mounting frame 4 and rotatably connected to the outer side of the shaft 6, and a shaft 6 installed on the side of the wheel 1 near the hopper 3 to drive the striking plate 5 to rotate along the fixed shaft 6. The system uses a push plate 7 that applies external force to the hopper 3 and an elastic element 8 that is positioned between the fixed shaft 6 and the striking plate 5 to assist the striking plate 5 in resetting after striking the hopper 3. Through the vibration assembly, the system utilizes the power generated by the rotation of the wheel 1 to drive the vibration assembly, eliminating the need for an additional power source, thus reducing energy consumption and cost. When the wheel 1 rotates, it can drive the push plate 7 to move, thereby pushing the striking plate 5 to rotate along the fixed shaft 6 and striking the hopper 3. This keeps the ash material in a loose state within the hopper 3, preventing the ash material from clumping due to long-term accumulation, thus ensuring that the ash material can be fed evenly and improving construction quality and efficiency.
[0031] Furthermore, such as Figure 3-4 As shown, the end of the striking plate 5 furthest from the hopper 3 is equipped with a guide plate 9 that cooperates with the push plate 7 and facilitates the push plate 7's rotation away from the striking plate 5. The guide plate 9 can be a column with a semi-circular cross-section at its free end, or the entire guide plate 9 can be set in a semi-circular arc shape. In this case, the direction of the curved end of the guide plate is consistent with the direction of rotation of the wheel 1, such as... Figure 3 As shown in the figure, this embodiment mainly describes that the guide plate is semi-circular in shape. By setting the guide plate 9, since the guide plate 9 has a curved surface, when the wheel 1 rotates and drives the push plate 7 to rotate and pass through the guide plate 9, it is convenient for the free end of the push plate 7 to slide along the curved surface of the guide plate 9, so as not to affect the normal rotation of the wheel 1 or apply too much force to the hopper 3, which would cause the hopper 3 to deform.
[0032] Furthermore, such as Figure 4 As shown, the striking plate 5 is provided with a plurality of elastic protrusions 10 evenly on one end near the hopper 3 and on the side facing the hopper 3. By providing a plurality of elastic protrusions 10 on the striking plate 5, the elastic protrusions 10 can be made of rubber or latex material, and can be spherical or square, etc. When the push plate 7 strikes the hopper 3, the elastic action of the elastic protrusions 10 can not only reduce the striking force of the striking plate 5 on the hopper 3, but also assist the striking plate 5 in resetting.
[0033] Furthermore, such as Figure 1-2 As shown, the number of push plates 7 is at least one, and the free end of the push plate 7 extends to the connection between the guide plate 9 and the push plate 7. The number of push plates 7 can be one or more. Multiple push plates 7 are evenly distributed on the wheel 1, which can increase the frequency of the striking plate 5 striking the hopper 3, so that the ash material in the hopper 3 always remains in a loose state, avoiding agglomeration and blockage of the discharge hopper 3.
[0034] Furthermore, such as Figure 3-4 As shown, the number of vibration components is at least one set. When the number of vibration components is set to one set, the vibration components can be set on one side of the hopper 3, that is, in the lower half of the hopper 3, close to the discharge port of the hopper 3. The discharge of the hopper 3 can be controlled by the valve 11. When the valve 11 is opened, the ash material leaks out from the discharge port. When the number of vibration components is two sets, they can be symmetrically distributed on both sides of the hopper 3, or distributed vertically on both sides of the hopper 3, thereby improving the vibration effect of the vibration components.
[0035] Furthermore, such as Figure 3-4As shown, when wheel 1 is not rotating, the end of the striking plate 5 away from wheel 1 is in contact with the outer wall of hopper 3. When wheel 1 is not rotating, push plate 7 will not push striking plate 5. At this time, striking plate 5 is in contact with the surface of hopper 3 but does not apply external force to hopper 3. The elastic element 8 between striking plate 5 and fixed shaft 6 is not affected by external force and will not affect the installation and disassembly of hopper 3. The elastic element 8 can be a spring, one end of which is connected to the top of fixed shaft 6 and the other end is connected to the top wall of striking plate 5. When handle 12 is pushed, wheel 1 is driven along... As the bearing 2 rotates, it drives the entire ash sprinkler to move along the ground. When the push plate 7 rotates with the wheel 1 and comes into contact with the guide plate 9, it drives the striking plate 5 to swing one end near the wheel 1 toward the side closer to the push plate 7, and the other end to swing away from the hopper 3. At this time, the elastic element 8 is in a stretched state. After the push plate 7 rotates away from the striking plate 5, the striking plate 5 is driven to reset under the elastic action of the elastic element 8. During the reset process of the striking plate 5, the striking plate 5 will continuously strike the surface of the hopper 3 until the striking plate 5 is completely reset.
