Description

Technical Field

[0001] The utility model relates to the technical field of subgrade construction, and particularly relates to a construction device for filling soil of a highway subgrade. Background Art

[0002] The main components of a highway are the road surface and the subgrade. The subgrade is the foundation of the road surface and is excavated or filled and compacted on the original ground. Subgrade filling refers to the operation of filling soil in road construction to ensure the flatness and stability of the road surface. Subgrade filling plays a crucial role in the service life and performance of the road.

[0003] When filling soil for the subgrade during construction, a series of steps need to be experienced, including surveying and setting out, road surface drainage, surface cleaning, soil filling, moisture content measurement, road surface leveling, vibration compaction, and finally finishing and shaping. Each step requires a lot of time and manpower and is very cumbersome. The existing soil filling construction devices are difficult to combine these steps, difficult to shorten the filling construction period, and greatly waste manpower and time. Content of the Utility Model

[0004] The purpose of the utility model is to provide a construction device for filling soil of a highway subgrade to solve the above deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

A water spray head 404 is provided on one side surface of the water pipe 403. A flow valve 402 is provided on the upper surface of the water pipe 403.

[0031] In the present utility model, the driving motor 301 is provided to drive the driving rod 3 to rotate. The screening block 305 is reciprocally linearly pulled by the connecting rod 304 to screen the earthwork during filling, ensuring the fineness of the earthwork and greatly improving the filling quality. When the moisture content of the earthwork does not meet the requirements, the earthwork is sprayed by the water spray head 404, and the flow valve 402 adjusts the water output to ensure the moisture content of the earthwork.

[0032] In a further embodiment provided by the present utility model, a first connecting block 202 is fixedly connected to one side surface inside the housing 102. One end of the first connecting block 202 is rotatably connected to a connecting strip 203. One end of the connecting strip 203 is rotatably connected to a second connecting block 204.

[0033] Furthermore, the first connecting block 202, the connecting strip 203, and the second connecting block 204 are all in two groups, and are mirror-symmetrical with respect to the vertical bisector of the sieve plate 201. And there are four first connecting blocks 202, connecting strips 203, and second connecting blocks 204 in each group, and they are evenly arranged in an array on one side surface of the screening frame 2.

[0034] In a further embodiment provided by the present utility model, a screening frame 2 is fixedly connected to one end of the second connecting block 204. A sieve plate 201 is provided inside the screening frame 2. A screening removal plate 205 is connected to one side surface of the sieve plate 201. Two baffle plates 206 are fixedly connected to the upper surface of the screening removal plate 205.

[0035] In a further embodiment provided by the present utility model, a limiting groove 307 is slidably connected to the outside of the screening block 305. Two reset springs 306 are connected to both ends of the screening block 305. One end of each of the two reset springs 306 is respectively connected to both ends inside the limiting groove 307. The upper surface of the screening block 305 is fixedly connected to the lower surface of the screening plate 201. Two fixing plates 308 are fixedly connected to the outer surfaces on both sides of the limiting groove 307. One end of each of the two fixing plates 308 is respectively fixedly connected to both sides inside the housing 102.

[0036] Specifically, when the screening plate 201 screens soil, the connecting bar 203 moves back and forth along with the screening plate 201, ensuring the movement amplitude of the screening. The reset spring 306 pulls the screening plate 201 back to its original position to prevent the screening plate 201 from moving excessively.

[0037] In a further embodiment provided by the present utility model, a water tank 4 is provided on one side surface of the housing 102. An outlet hole is also provided on the same side surface of the housing 102. A water outlet pipe 401 is communicated with one side surface of the water tank 4.

[0039] In a further embodiment provided by the present utility model, a first fixing bar 501 is rotatably connected to one side surface of the housing 102. A leveling bucket 5 is connected to one end of the first fixing bar 501.

[0040] In a further embodiment provided by the present utility model, a second fixing bar 503 is rotatably connected to one side surface of the housing 102. A compaction wheel 502 is rotatably connected to one end of the first fixing bar 501.

[0041] In the present utility model, when in use, the operator drives the vehicle body 1 to the designated construction site, adds earthwork materials through the feeding port 103, starts the driving motor 301 to drive the driving rod 3 to rotate, the driving rod 3 drives the driving strip 302 to rotate around the driving rod 3 as the axis, the connecting rod 304 converts the rotational motion of the driving strip 302 into a reciprocating linear motion, and simultaneously reciprocally pulls the screening block 305, so that it drives the screening plate 201 to reciprocally screen the earthwork materials. The screened miscellaneous materials are discharged through the screening port 105 along with the screening plate 205. During screening, the connecting strip 203 moves back and forth with the screening plate 201 to ensure the amplitude of the screening motion. The return spring 306 pulls the screening plate 201 back to its original position to prevent the screening plate 201 from moving excessively. Water is stored in advance in the water tank 4. When the moisture content of the earthwork does not meet the requirements, the earthwork is sprayed through the spray head 404. The flow valve 402 adjusts the water output to ensure the moisture content of the earthwork. After the earthwork materials are qualified in screening and moisture content, they fall onto the roadbed through the discharge inclined plate 104. Subsequently, when the vehicle body 1 is driven forward, the leveling bucket 5 levels the earthwork to make it flat. When driving continuously, the compaction wheel 502 vibrates and compacts to shape the roadbed, completing the roadbed filling in one go without multiple processes.

[0042] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
