Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway engineering construction technology, and in particular to a simple line marking device for highway engineering construction. Background Technology
[0002] Spreading lime lines is a common task in highway engineering, used to control the slopes or width of roads on both sides. Currently, during construction, workers rely on a shovel in one hand and a wooden stick in the other to strike the shovel handle, transmitting vibrations to the shovel and causing lime to fall from the shovel surface to mark the lines. This method is inefficient, and the lines are uneven in thickness due to manual spreading. Furthermore, the shovel head is often at varying heights from the ground, making the lime easily scattered by the wind and polluting the environment. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses a simple line marking device for highway engineering construction, comprising a first frame and a front roller connected to the bottom of the first frame. A first extension rod is connected to the top of the first frame, and a handle is connected to the top of the first extension rod. A second extension rod is hinged to the body of the first extension rod, and the other end of the second extension rod is connected to a second frame. An auxiliary roller is connected to the bottom of the second frame. A limiting plate is provided above the hinge position of the second extension rod and the first extension rod, and the limiting plate is connected to the first extension rod. A hopper is connected to the body of the first extension rod, and a valve is connected to the bottom of the hopper. A material guide is connected to the valve, and the material guide is connected to the second extension rod and an L-shaped rod through a fastening assembly. One end of the L-shaped rod is connected to the second frame, and the other end of the L-shaped rod is located behind the auxiliary roller.
[0006] Furthermore, the bottom of the hopper is a constricted discharge port, and the valve is connected to the discharge port.
[0007] Furthermore, the hopper is connected to the first extension rod by a clamp.
[0008] Furthermore, both the first and second frames include a U-shaped frame and a connecting rod connected to the U-shaped frame, and the ends of the first and second extension rods are respectively connected to the ends of the corresponding connecting rods.
[0009] Furthermore, a stabilizing element is installed on the U-shaped frame.
[0010] Furthermore, the fastening assembly includes a fastening ring and an open retaining ring connected to the fastening ring. The fastening ring is sleeved on the second extension rod and the L-shaped rod, and the feed guide is held in the open retaining ring.
[0011] Furthermore, a rubber anti-slip sleeve is provided on the outer surface of the grip.
[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0013] This utility model has a simple structure, reasonable design, convenient operation, and is easy to implement. It can reduce workload, improve work efficiency, improve the uniformity of lime spreading, control the flow rate of lime, and ensure that the width is the same and the neatness is high. The distance between the lime spreading port and the ground is close, which makes it less likely to cause dust. It changes the traditional construction method. Attached Figure Description

Detailed Implementation
[0019] like Figure 1-3 As shown, a simple line marking device for highway construction includes a first frame 1 and a front roller 2 connected to the bottom of the first frame 1. A first extension rod 3 is connected to the top of the first frame 1, and a handle 4 is connected to the top of the first extension rod 3. A rubber anti-slip sleeve is provided on the outer surface of the handle 4.
[0020] A second extension rod 13 is hinged to the body of the first extension rod 3. The other end of the second extension rod 13 is connected to a second frame 7. An auxiliary roller 8 is connected to the bottom of the second frame 7. A limiting plate 9 is provided above the hinge point of the second extension rod 13 and the first extension rod 3. The limiting plate 9 is connected to the first extension rod 3. The limiting plate 9 restricts the rotation angle of the second extension rod 13, ensuring that the distance between the front roller 2 and the auxiliary roller 8 is equal and the included angle between the first extension rod 3 and the second extension rod 13 is equal during use.
[0021] A hopper 5 is connected to the body of the first extension rod 3 via a clamp 12. The bottom of the hopper 5 is a constricted discharge port, and a valve 6 is connected to the bottom of the hopper 5. The valve 6 is connected to the discharge port. A feed guide 10 is connected to the valve 6. The feed guide 10 is connected to the second extension rod 13 and the L-shaped rod 11 via a fastening assembly. One end of the L-shaped rod 11 is connected to the second frame 7, and the other end of the L-shaped rod 11 is located behind the auxiliary roller 8.
