Description

Technical Field

[0001] This application belongs to the field of road and bridge construction technology, and more specifically, relates to a portable, mobile median-type soil filling and pollution prevention funnel. Background Technology

[0002] Currently, loaders are commonly used as the primary means of transporting soil during median strip filling construction. The specific operation involves the loader delivering soil to the construction site and dumping it directly onto the shoulder or median strip area. An excavator then levels the dumped soil. However, it is inevitable that soil will spill onto the asphalt pavement during dumping. This spilled soil, under the pressure of passing vehicles, embeds itself into the asphalt's texture, forming stubborn stains and causing wear. This affects the pavement's anti-skid properties, increases driving safety hazards, and requires significant time for subsequent road cleaning and repair, wasting manpower and resources. Utility Model Content

[0003] Based on the above-mentioned technical problems, this application provides a portable mobile median-type soil filling and pollution prevention funnel to solve the technical problem in the prior art where soil is scattered on the asphalt road surface when dumping soil by dump trucks, requiring a lot of time to clean and repair the road surface, which wastes manpower and resources.

Each support leg is provided with a first roller at its bottom end. The frame is provided with telescopic positioning components on both sides of the median strip. The axial direction of the telescopic positioning components is perpendicular to the axial direction of the median strip. The free ends of the two telescopic positioning components abut against the two side walls of the median strip. A scraper is fixed on the side of the frame facing away from the direction of movement.

[0005] Furthermore, the hopper has a trapezoidal cross-section that is wider at the top and narrower at the bottom. The top of the hopper is used to receive the soil output by the loader, and the bottom of the hopper is located directly above the median strip.

[0006] Furthermore, the frame includes an upper fixed frame and a lower fixed frame fixedly disposed on the outer edge of the top end of the hopper and the outer edge of the bottom end of the hopper, and a plurality of first reinforcing rods evenly distributed on the outer wall of the hopper. The two ends of the plurality of first reinforcing rods are respectively fixedly connected to the upper fixed frame and the lower fixed frame. Support rods are respectively fixedly disposed at the four corners of the upper fixed frame. The four legs are respectively detachably connected to the four support rods. Adjacent support rods are respectively fixedly connected to each other by a second reinforcing rod.

[0007] Furthermore, each of the telescopic positioning components includes a fixed rod that is hollow inside and open at one end, a slide rod that is slidably disposed at one end inside the fixed rod, and a second roller disposed at the other end of the slide rod. A screw is rotatably disposed inside the fixed rod, and a threaded hole is provided at one end of the slide rod. The screw is screwed into the threaded hole, and a power unit for driving the screw to rotate is provided on one side of the fixed rod.

[0008] Furthermore, the power unit includes a Z-shaped rocker arm, one end of which passes through the interior of the fixed rod and is rotatably connected to the fixed rod. A first helical gear is fixedly sleeved on one end of the rocker arm located inside the fixed rod, and a second helical gear that meshes with the first helical gear is fixedly mounted on the end of the screw away from the slide rod.

[0009] Furthermore, a connecting plate is fixed inside the fixing rod, and the end of the screw away from the slide rod passes through the connecting plate and is rotatably connected to the connecting plate.

[0010] Furthermore, a connecting rod is fixedly provided on one side of the fixing rod, and the free end of the connecting rod passes through the second reinforcing rod and is fixedly connected to the second reinforcing rod by bolts.

[0011] Furthermore, the connecting rod is provided with a plurality of through-holes, which are evenly arranged along the axial direction of the connecting rod, and the bolts are inserted into the corresponding connecting holes.

[0012] Furthermore, the lower part of each of the four support rods is provided with a through hole, and the multiple through holes are evenly arranged along the axial direction of the support rod. Each leg includes a sleeve with an open top and a hollow interior. The four legs are slidably sleeved on the lower part of the four support rods and are fixedly connected by bolts and the corresponding through holes.

[0023] Please refer to the following: Figures 1 to 3 As shown, the following describes a portable mobile median strip filling and pollution prevention funnel provided in an embodiment of this application. This portable mobile median strip filling and pollution prevention funnel includes: a frame 1, a hopper 2, four support legs 3, four first rollers 4, a telescopic positioning assembly 5, and a scraper 6. The hopper 2 is composed of multiple steel plates and is used to receive soil transported by a loader (existing technology). The cross-section of the hopper 2 is a trapezoidal structure, wider at the top and narrower at the bottom. The top of the hopper 2 is used to receive soil output by the loader, and the bottom of the hopper 2 is located directly above the median strip 7. It should be noted that the median strip 7 is existing technology, located in the middle of a two-way lane, used to prevent interference between vehicles in both directions. It is generally constructed using two precast concrete guardrails 71 spaced apart, with soil placed between the two guardrails 71 and plants planted to increase the green area. The bottom of the hopper 2 is located between the two precast concrete guardrails 71, which will not be elaborated further here.

[0024] The frame 1 is constructed from multiple square steel bars and serves to support the hopper 2. The frame 1 includes an upper fixed frame 11, a lower fixed frame 12, first reinforcing rods 13, support rods 14, and second reinforcing rods 15. The upper fixed frame 11 is fixedly positioned at the outer edge of the top of the hopper 2, and the lower fixed frame 12 is fixedly positioned at the outer edge of the bottom of the hopper 2. Multiple first reinforcing rods 13 are evenly distributed on the outer wall of the hopper 2, with their ends fixedly connected to the upper fixed frame 11 and the lower fixed frame 12, respectively. Four support rods 14 are provided, with their top ends fixedly connected to the four corners of the bottom surface of the upper fixed frame 11. Adjacent support rods 14 are fixedly connected via second reinforcing rods 15. This forms a stable support structure covering the outside of the hopper 2.

[0025] Four support legs 3 are detachably mounted at the four corners of the frame 1. In this embodiment, each support leg 3 is detachably connected to one of the four support rods 14. Specifically, each support leg 3 includes a sleeve with an open top and a hollow interior. The four support legs 3 are slidably fitted onto the lower part of the four support rods 14 and fixedly connected to the corresponding support rods 14 by bolts. Four first rollers 4 are respectively located at the ends of the four support legs 3 away from the support rods 14. Thus, the four first rollers 4 drive the movement of the four support legs 3 and the frame 1.

[0026] Preferably, the lower part of each of the four support rods 14 is provided with a through hole 141, and the multiple through holes 141 are evenly arranged along the axial direction of the support rods 14. In implementation, bolts can be fixedly inserted into the corresponding through holes 141 according to actual needs to accommodate the height of the precast concrete on both sides of the median strip.

[0027] Two telescopic positioning components 5 are respectively installed on both sides of the frame 1 located on the center divider. Specifically, the two telescopic positioning components 5 are fixedly connected to the second reinforcing rods 15 on both sides of the frame 1 located on the center divider. The axis of the telescopic positioning components 5 is perpendicular to the axis of the center divider, and the free ends of the two telescopic positioning components 5 abut against the two side walls of the center divider. This ensures the stability of the frame 1 during movement and prevents displacement.

[0028] In this embodiment, each telescopic positioning component 5 includes a fixed rod 51, a sliding rod 52, a second roller 53, and a screw 54. The fixed rod 51 is a rectangular cylinder with a hollow interior and an open end. One end of the sliding rod 52 is slidably disposed within the fixed rod 51. It should be noted that the inner wall of the fixed rod 51 is also rectangular, while the outer wall of the sliding rod 52 is adapted to the inner wall of the fixed rod 51. Therefore, the sliding rod 52 can only slide along the axial direction of the fixed rod 51 and cannot rotate inside the fixed rod 51. The second roller 53 is disposed at the other end of the sliding rod 52 (the end away from the fixed rod 51). The screw 54 is rotatably disposed inside the fixed rod 51. Specifically, a connecting plate 55 is fixed inside the fixed rod 51, and the end of the screw 54 away from the sliding rod 52 passes through the connecting plate 55 and is rotatably connected to it. One end of the sliding rod 52 has a threaded hole 521, and the screw 54 is screwed into the threaded hole 521.

[0029] During implementation, the screws 54 of the two telescopic positioning components 5 are driven to rotate. Since the screws 54 are screwed into the threaded holes 521, the rotation of the screws 54 causes the slide bar 52 to slide within the fixed rod 51. The second roller 53 at the other end of the slide bar 52 moves accordingly until the free ends of the two telescopic positioning components 5 abut against the two side walls of the median strip. The telescopic positioning components 5 ensure the stable positioning of the frame 1 on the median strip, preventing the hopper 2 from shifting during movement. Furthermore, the telescopic positioning components 5 can adapt to median strips of different widths.

[0030] In this embodiment, a power unit 56 for driving the screw 54 to rotate is provided on one side of the fixed rod 51. Specifically, the power unit 56 includes a Z-shaped rocker arm 561. One end of the rocker arm 561 passes through the interior of the fixed rod 51 and is rotatably connected to the fixed rod 51. A first helical gear 562 is fixedly sleeved on the end of the rocker arm 561 located inside the fixed rod 51, and a second helical gear 563 that meshes with the first helical gear 562 is fixedly mounted on the end of the screw 54 away from the slide bar 52. In practice, rotating the rocker arm 561 sequentially drives the first helical gear 562 and the second helical gear 563 to rotate, thereby driving the screw 54 to rotate, thereby realizing the extension and retraction of the slide bar 52 within the fixed rod 51.

[0031] Preferably, a connecting rod 57 is fixedly provided on one side of the fixing rod 51, and the free end of the connecting rod 57 passes through the second reinforcing rod 15 and is fixedly connected to the second reinforcing rod 15 by bolts. In implementation, the free end of the connecting rod 57 on one side of the fixing rod 51 is passed through the second reinforcing rod 15, and then the connecting rod 57 is fixedly connected to the second reinforcing rod 15 by bolts, thereby realizing the connection between the telescopic positioning assembly 5 and the frame 1, so as to facilitate the installation and disassembly of the telescopic positioning assembly 5.

[0032] Preferably, the connecting rod 57 is provided with multiple through-holes 571, which are evenly arranged along the axial direction of the connecting rod 57. Bolts are inserted into the corresponding connecting holes 571. In implementation, appropriate connecting holes 571 can be selected according to actual needs, and bolts can be placed in the corresponding connecting holes 571 to fix the connecting rod 57 and the second reinforcing rod 15 at different positions, thereby adjusting the position of the telescopic positioning component 5 on the frame 1. This allows for flexible adjustment of the position of the telescopic positioning component 5 according to the different widths and heights of the center strip, further improving adaptability and versatility.

[0033] The scraper 6 is fixedly installed on the side of the frame 1 facing away from the direction of movement to clean up soil scattered in the median strip (top of the precast concrete). Specifically, the scraper 6 is V-shaped, with the open end of the V-shaped scraper 6 facing the same direction as the movement of the hopper 2, and the bottom surface of the scraper 6 is slidably mounted on the top surface of the median strip. In this way, during the movement of the hopper, the scraper 6 can clean and organize the soil at the edge of the median strip.

[0034] Preferably, the scraper 6 has straight grooves 61 at both ends, the axial direction of which is parallel to the width direction of the scraper 6. Bolts are provided at both ends of the scraper 6, and one end of each bolt passes through the corresponding straight groove 61 and is screwed to the corresponding second reinforcing rod 15. By adjusting the position of the bolts in the straight groove 61, the height of the scraper 6 can be finely adjusted so that the bottom surface of the scraper 6 can better fit the edge of the median strip, thereby better cleaning up the scattered soil and improving the cleanliness of the construction.

[0035] In the specific implementation of this utility model, the hopper 2 and the frame 1 are pre-assembled, which can be connected by welding. The frame 1 is placed above the median strip, and then the four support legs 3 are slidably sleeved on the lower part of the four support rods 14 respectively. According to the height of the precast concrete on both sides of the median strip, the bolts are passed through the corresponding through holes 141 at the lower part of the support rods 14 to fix the support legs 3 to the corresponding support rods 14 (the four first rollers 4 are set at the end of the four support legs 3 away from the support rods 14).

[0036] The free ends of the connecting rods 57 of the two telescopic positioning components 5 are inserted into the corresponding second reinforcing rods 15. A suitable connecting hole 571 is selected according to actual needs, and the connecting rods 57 and the second reinforcing rods 15 are fixedly connected with bolts. Then, the Z-shaped rocker arm 561 is rotated. The rocker arm 561 drives the first helical gear 562 to rotate, which in turn drives the second helical gear 563, which is fixed to one end of the screw rod 54, to rotate. Since the screw rod 54 is screwed into the threaded hole 521 at one end of the slide rod 52, the rotation of the screw rod 54 causes the slide rod 52 to slide within the hollow, one-end-open fixed rod 51. The second roller 53 at the other end of the slide rod 52 moves accordingly until the free ends of the two telescopic positioning components 5 respectively abut against the two side walls of the center strip, achieving stable positioning of the frame 1 on the center strip.

[0037] Next, the loader dumps the soil onto the top of hopper 2. The soil falls accurately through the bottom opening of hopper 2 into the median strip 7, which is located in the middle of the two-way lane and consists of two precast concrete guardrails 71. The four first rollers 4 drive the four outriggers 3 and the frame 1 to move. The scraper 6, which is fixed on the side of the frame 1 facing away from the direction of movement, cleans and tidies up the soil scattered at the edge of the median strip during the movement of the hopper. At the same time, the position of the bolts at both ends of the scraper 6 in the straight groove 61 can be adjusted according to the actual situation to fine-tune the height of the scraper 6 so that its bottom surface better fits the edge of the median strip.

[0038] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.
