Description

Technical Field

[0001] This utility model relates to the field of soil paving technology, specifically to a soil paving vehicle. Background Technology

[0002] Embankment projects are water-retaining structures built along the banks of rivers, lakes, and seas. Their core functions include flood control, tide prevention, and protection of coastal urban areas and farmland. At embankment construction sites, before compacting soil with high moisture content, soil pavers are used to spread the soil to facilitate subsequent operations and improve the compaction quality.

[0003] In the actual paving process, existing soil pavers may spread too much or too little soil, resulting in uneven paving, which in turn leads to uneven compaction and reduces the overall structural strength of the embankment. Utility Model Content

[0004] The purpose of this utility model is to provide a soil paver to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A soil paver includes a main body with a soil storage box installed inside. A discharge port is located at the front bottom of the soil storage box, and a replenishment port is located at the rear bottom. A first servo cylinder and a horizontally arranged first slide rail are installed at the bottom of the discharge port. An L-shaped first adjusting plate is hinged to the output end of the first servo cylinder. The upper end of the first adjusting plate is slidably connected to the first slide rail, and the lower end of the first adjusting plate covers the discharge port. The discharge rate of the discharge port can be adjusted by controlling the first servo cylinder. A second servo cylinder and a horizontally arranged second slide rail are installed at the bottom of the replenishment port. An L-shaped second adjusting plate is hinged to the output end of the second servo cylinder. The upper end of the second adjusting plate is slidably connected to the second slide rail, and the lower end of the second adjusting plate covers the replenishment port. The discharge rate of the replenishment port can be adjusted by controlling the second servo cylinder.

[0006] Furthermore, the left and right widths of the discharge port are the same as the left and right widths of the soil storage box, and the left and right widths of the replenishment port are the same as the left and right widths of the soil storage box.

[0007] Furthermore, a bracket is installed on the main body, and an electric push rod is installed on the bracket. The output end of the electric push rod is positioned facing the opening of the soil storage box, and a cover plate is installed on the output end of the electric push rod to seal the opening of the soil storage box.

[0008] Furthermore, it also includes a rotating shaft that passes through the soil storage box and whose two ends are rotatably connected to the main body; it also includes an adjusting cylinder, one end of which is hinged to the side of the soil storage box and the other end of which is hinged to the main body.

[0009] Furthermore, the discharge size of the discharge port is larger than that of the replenishment port. A photoelectric thickness gauge is installed between the discharge port and the replenishment port. The photoelectric thickness gauge detects the thickness of the material after paving at the discharge port and sends the data back to the replenishment port for replenishment.

[0010] Furthermore, the bottom of the body is provided with toothed rollers, and the rear end of the body is provided with a handrail.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects: A first servo cylinder is installed at the bottom of the discharge port, controlling the opening and closing of the first adjusting plate to regulate the discharge volume. A second servo cylinder is installed at the bottom of the replenishment port, controlling the opening and closing of the second adjusting plate to regulate the amount of soil replenished. When the soil thickness is thick, the replenishment volume is reduced; when the soil thickness is thin, the replenishment volume is increased, thus balancing the soil spreading volume. This two-stage spreading of the soil ensures uniform spreading and compaction, thereby guaranteeing the structural strength of the embankment. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0019] like Figures 1-4 As shown, a soil paver includes a body 1, and a soil storage box 2 is installed inside the body 1; the soil storage box 2 has a discharge port 21 at the front end of the bottom and a replenishment port 22 at the rear end of the bottom. The bottom of the discharge port 21 is equipped with a first servo cylinder 211 and a horizontally arranged first slide rail 213. The output end of the first servo cylinder 211 is hinged to an L-shaped first adjusting plate 212. The upper end of the first adjusting plate 212 is slidably connected to the first slide rail 213, and the lower end of the first adjusting plate 212 covers the discharge port 21. The discharge amount of the discharge port 21 can be adjusted by controlling the first servo cylinder 211. The bottom of the feeding port 22 is equipped with a second servo cylinder 221 and a horizontally arranged second slide rail 223. The output end of the second servo cylinder 221 is hinged to an L-shaped second adjusting plate 222. The upper end of the second adjusting plate 222 is slidably connected to the second slide rail 223, and the lower end of the second adjusting plate 222 covers the feeding port 22. The discharge amount of the feeding port 22 can be adjusted by controlling the second servo cylinder 221.

[0020] The material discharge from outlet 21 and the material replenishment from replenishment outlet 22 are controlled by a first servo cylinder 211 and a second servo cylinder 221, which can further increase the accuracy of material discharge and replenishment, ensuring a better final paving effect. The drive end of the first servo cylinder 211 is hinged to the side wall of outlet 21. When the output end of the first servo cylinder 211 is adjusted, the first servo cylinder 211 can change its own angle to adapt. The drive end of the second servo cylinder 221 is hinged to the side wall of replenishment outlet 22. It should be noted that even if the material discharge from outlet 21 is very precise, considering the unevenness of the paved road surface, it is difficult for outlet 21 to pave the material in one go and achieve a uniform paving effect. The first servo cylinder 211 controls the discharge amount, and the second servo cylinder 221 controls the amount of soil replenished by the feeding port 22. When the soil thickness is thick, the replenishment amount is small, and when the soil thickness is thin, the replenishment amount is large, thereby balancing the amount of soil spread. By spreading the soil twice, the uniformity of soil spreading is ensured, thereby ensuring uniform compaction and thus ensuring the structural strength of the embankment.

[0021] Furthermore, the left and right widths of the discharge port 21 and the soil storage box 2 are the same, as are the left and right widths of the replenishment port. Since both the discharge port 21 and the replenishment port 22 have the same left and right widths as the soil storage box 2, this maximizes the spread of a sufficiently wide area of ​​soil during the spreading process, thereby improving efficiency.

[0022] like Figure 5 As shown, furthermore, a bracket 3 is installed on the main body 1, and an electric push rod 4 is installed on the bracket 3. The output end of the electric push rod 4 is oriented towards the opening of the soil storage box 2, and a cover plate 5 is installed on the output end of the electric push rod 4. The cover plate 5 is used to seal the opening of the soil storage box 2. The piston rod of the electric push rod 4 drives the cover plate 5 to descend on the bracket 3, and the cover plate 5 can descend into the soil storage box 2 to cover the soil, prevent impurities from entering the soil, and ensure the purity of the soil.

[0023] Furthermore, it also includes a rotating shaft 24, which passes through the soil storage box 2 and whose two ends are rotatably connected to the body 1; it also includes an adjusting cylinder 25, one end of which is hinged to the side of the soil storage box 2 and the other end is hinged to the body 1. The rotating shaft 24 is provided, and its axial direction is the same as the forward direction of the invention. By controlling the adjusting cylinder 25 on the side of the soil storage box 2, the angle of the soil storage box 2 can be adjusted, thereby causing the soil storage box 2 to tilt, reducing the opening height of the soil storage box 2, and facilitating workers to load materials.

[0024] Furthermore, the discharge size of the discharge port 21 is larger than that of the replenishment port 22. A photoelectric thickness gauge 23 is installed between the discharge port 21 and the replenishment port 22. The photoelectric thickness gauge 23 detects the thickness of the soil after paving at the discharge port 21 and feeds the data back to the replenishment port 22 for replenishment. The discharge port 21 and the replenishment port 22 are set up. The discharge port 21 is set up in the soil storage box 2 for feeding and discharging soil during the paving process. Uneven feeding may occur during the feeding process. The photoelectric thickness gauge 23 at the bottom of the soil storage box 2 is used in conjunction with the continuously advancing paving vehicle to detect the thickness of the soil after the discharge port 21 has completed paving, and then controls the replenishment port 22 to replenish the soil, so as to complete a more uniform soil paving.

[0025] The photoelectric thickness gauge 23 employs a laser sensor based on existing technology. It accurately measures the thickness of the soil by emitting a laser beam onto the soil surface and receiving the reflected light. Furthermore, the laser sensor 23 is equipped with a data processing algorithm that can handle the non-uniformity and porosity of the soil, as well as changes in reflected light caused by variations in soil particle size and moisture content. By analyzing the reflected light data in real time, the algorithm can calculate the accurate soil thickness and feed the result back to the control system. The control system can then adjust the material replenishment based on the measured thickness data, thereby improving the efficiency and accuracy of thin-layer soil paving, reducing waste, and enhancing project quality.

[0026] Furthermore, the bottom of the main body 1 is provided with toothed rollers, and the rear end of the main body 1 is provided with a handrail. The toothed rollers make it easier to walk on the ground where the soil is spread, and the handrail is used by workers to push the invention.

[0027] This utility model involves electrically controlled devices such as a first servo cylinder 211 and a second servo cylinder 221. A controller and a battery are installed on the main body 1 for driving and controlling these devices. The controller here can be any existing controller capable of driving the aforementioned electrical components.

[0028] The technical effect of this utility model is to achieve a more uniform paving of soil material, not to achieve a sufficiently uniform paving, but rather that the uniform paving effect is better in two pavings than in a single paving.

The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
