[0002] Currently, both domestic and international highway maintenance have advanced and mature technologies and equipment. However, in terms of roadbed gully repair, mechanical and manual methods are still commonly used.

[0003] The common method for gully repair involves using dump trucks to transport materials to the repair location and then dumping them onto the road surface. However, if the materials cannot be accurately dumped into the gully, manual or mechanical methods are required to fill the gully with the materials. This method requires a relatively large and sufficient workforce and equipment. In addition, when the dump trucks are unloading materials, the materials also pollute the road surface, requiring workers to clean them up later, which increases the cost of road cleaning.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Reference Figure 1 - Figure 5 A roadbed slope gully laying device includes a material bin 1, a feeding screen 2 at the upper end of the material bin 1, protective plates 3 symmetrically arranged at the bottom of the material bin 1, a conveyor belt 4 between the protective plates 3, a support plate 5 on the outer side of the protective plates 3, the support plate 5 can support the material bin 1 in the carriage of a transport vehicle, a discharge port 6 at one end of the material bin 1, and the ends of the protective plates 3 and the conveyor belt 4 both extend to the outside of the discharge port 6.

[0031] The conveyor belt 4 is provided with a fabric distribution assembly below its end; the fabric distribution assembly includes a chute-type fabric distribution plate 7, one end of which is rotatably connected to the guard plate 3, and two connecting rods 8 are rotatably connected to the middle position of the chute-type fabric distribution plate 7. A T-shaped tube 9 is rotatably connected to the connecting rod 8. The end of the T-shaped tube 9 is fixedly connected to the output end of the first hydraulic cylinder 10, and the cylinder body of the first hydraulic cylinder 10 is fixedly connected to the guard plate 3. The other end of the chute-type fabric distribution plate 7 extends downward at an incline to the top of the roadbed ditch.

[0032] In this embodiment, the use of the roadbed slope gully laying equipment is relatively simple and flexible. It only requires finding a transport vehicle that matches the material bin 1. The roadbed slope gully laying equipment is then transferred to the transport vehicle's cargo box using a crane. The entire material bin 1 is then erected inside the cargo box using support plates 5. An excavator then feeds materials such as sand and gravel into the material bin 1 from the top port. Under the screening of the feed screen 2, large-diameter fragments are removed, and the qualified materials fall into and accumulate in the material bin 1. After filling, the transport vehicle is driven to the construction site. The distance between the transport vehicle and the roadbed is then controlled, and the other end of the chute-type laying plate 7 is positioned above the roadbed gully. Then, the transport vehicle is slowly started, and the conveyor belt 4 is driven by a motor. The conveyor belt 4 conveys the material at the bottom of the material bin 1 to the chute-type material distribution plate 7, and then rolls down into the ditch along the inclined trend of the chute-type material distribution plate 7. The amount of material flowing into the ditch is controlled by the transmission speed of the conveyor belt 4 to ensure that the material flows into the ditch as much as possible, avoiding overflow onto the road surface and causing road pollution, or avoiding scattering outside the roadbed and causing material waste. At the same time, by controlling the first hydraulic cylinder 10, the end height of the chute-type material distribution plate 7 is controlled to realize the parabolic route adjustment of the material, which is flexibly applicable to the indirect connection between the transport vehicle and the roadbed, ensuring that the material falls accurately into the ditch.

[0033] Reference Figure 5 The chute-type material distribution plate 7 has an extension plate 11 on its lower surface. The inner wall of the extension plate 11 has a slide bar 12, and the inner wall of the chute-type material distribution plate 7 has a guide groove 13. The slide bar 12 is slidably connected in the guide groove 13. The rear end of the extension plate 11 is fixedly connected to the output end of the second hydraulic cylinder 14. The second hydraulic cylinder 14 can push and pull the extension plate 11 to slide along the lower surface of the chute-type material distribution plate 7. By setting the extension plate 11, the effective material guiding stroke of the chute-type material distribution plate 7 is extended. In some roadbeds where transport vehicles cannot approach, the material can be guided into the ditch by operating the extension plate 11. The second hydraulic cylinder 14 is driven to push the extension plate 11 to extend towards the other end of the chute-type material distribution plate 7, so that the end of the extension plate 11 extends close to the ditch. The material flows along the chute-type material distribution plate 7 onto the extension plate 11, and then rolls from the extension plate 11 into the ditch, realizing accurate material delivery.

[0034] Reference Figure 1 , Figure 2 and Figure 4The feeding screen 2 includes a screen and a support assembly. The support assembly includes a crossbeam 15 and an inverted V-shaped frame 16. The crossbeam 15 is arranged along the length of the material bin 1 and is supported at the upper port of the material bin 1 by the V-shaped frame 16. When the excavator feeds a bucket of material onto the feeding screen 2, the material will press down on the feeding screen 2 as a whole, which may damage the feeding screen 2. Therefore, the support assembly is set up. The V-shaped frame 16 and the crossbeam 15 cooperate to support the screen and withstand greater downward pressure, thus protecting the screen.

[0035] Reference Figure 1 The material silo 1 has baffles 17 on both sides of its upper port. Multiple atomizing nozzles 18 are installed on the inner wall of the baffles 17. The rear end of the atomizing nozzles 18 is connected to a water pipe. When materials are put into the material silo 1, the materials raise dust and pollute the working environment. Therefore, the atomizing nozzles 18 are installed. The water mist discharged by the atomizing nozzles 18 suppresses the dust on site and reduces the harm to the workers. At the same time, when the materials need to be replenished with water, water can be sprayed evenly on the materials through the atomizing nozzles 18. This spraying process can be carried out during the transportation of the vehicle to the construction site, saving time and improving efficiency.

[0036] Reference Figure 1 , Figure 6 and Figure 7 A roller pressing assembly is provided on one side wall of the rear end of the material silo 1. The roller pressing assembly includes a fixing plate 19, which is welded to the material silo 1. A connecting rod 20 is fixed to the fixing plate 19. The vertical end of the connecting rod 20 points to the bottom surface. A rotating groove 21 is opened at the vertical end of the connecting rod 20. An extrusion wheel 22 is rotatably connected in the rotating groove 21, and the extrusion wheel 22 is located in front of the other end of the chute-type material distribution plate 7. Before the material is distributed, the ditch of the roadbed slope needs to be cleaned to remove foreign objects. At the same time, the loose soil in the ditch needs to be hardened to ensure the stability of the base layer. For this purpose, an extrusion wheel 22 is set. The extrusion wheel 22 rolls along the ditch to compress and harden the loose soil in the ditch, so that the ditch can be filled at one time when the material is added, and no secondary material replenishment is required, saving time and improving efficiency.

[0037] Reference Figure 1 and Figure 6The connecting rod 20 includes a T-shaped fixing seat 23 and an L-shaped rod body 24. The fixing seat 23 is fixed to the fixing plate 19. The end of the fixing seat 23 rotates the horizontal end of the connecting rod 20 through a torsion spring. A groove 25 is opened on the vertical end of the rod body 24. A sleeve 26 is provided in the groove 25. The sleeve 26 is sleeved on the shaft of the extrusion wheel 22. A guide rod 27 is fixed above the sleeve 26. The guide rod 27 can move upward. A compression spring 28 is sleeved on the outer ring of the guide rod 27. One end of the compression spring 28 is fixed to the top surface inside the groove 25, and the other end of the compression spring 28 is fixed to the sleeve 26. The connecting rod 20 is composed of the fixing seat 23 and the rod body 24, which allows the extrusion wheel 22 to swing flexibly. At the same time, the shaft of the extrusion wheel 22 is connected to the groove 25 through the compression spring 28. The extrusion wheel 22 can move up and down with buffer, adapting to the unevenness of the groove and reducing the destructive extrusion of the extrusion wheel 22 by the inner sidewall of the groove.

[0038] Reference Figure 6 and Figure 7 The extrusion wheel 22 has multiple water spray holes 29 on its surface. The extrusion wheel 22 and the shaft are hollow. One end of the shaft is connected to a water pipe through a hose 30. Water is injected into the hollow extrusion wheel 22 and discharged from the water spray holes 29. While rolling, water is drained to moisten the trench. This is suitable for relatively dry areas. It replenishes moisture so that the powdery material solidifies at the bottom of the trench and compacts the trench.

[0039] Reference Figure 6 and Figure 9 The extrusion roller 22 has multiple sleeves 31 evenly fixed inside. One end of each sleeve 31 extends to the outer surface of the extrusion roller 22, and the other end of each sleeve 31 has a water inlet 32. A push rod 33 is installed inside each sleeve 31. One end of the push rod 33 is slidably connected to the sleeve 31 by a spring, and the other end of the push rod 33 is tapered. The shape of the inner part of one end of the sleeve 31 is adapted to match the shape of the other end of the push rod 33. Water inlets 34 are symmetrically opened in the middle of the sleeve 31. The push rods 33 on the extrusion roller 22 are not pressed into the groove. On the inner bottom surface, water flows out from the spray hole 29 of the top rod 33. The spray hole 29 drains water in an atomized state to reduce dust on the material guided down by the chute-type material distribution plate 7, providing a good working environment for the staff behind the transport vehicle. The top rod 33 on the extrusion wheel 22 is pressed against the bottom surface of the groove. The top rod 33 is compressed into the sleeve 31. Water flows in from the water inlet 34 on the sleeve 31 and is discharged from one end of the sleeve 31. At this time, the water flow is large, which can fully wet the inside of the groove, so that the material can fully absorb water and solidify.

[0040] Reference Figure 1The other end of the chute-type material distribution plate 7 is fixed with multiple steel wires 35, and the ends of the steel wires 35 are tied to a triangular frame set on the rear end face of the material bin 1. The bottom end of the chute-type material distribution plate 7 is pulled by the steel wires 35 to ensure the stability of the chute-type material distribution plate 7 and to prevent the material from pressing down on the chute-type material distribution plate 7, which could damage the first hydraulic cylinder 10, the connecting rod 8 and the T-shaped pipe 9.

[0041] Reference Figure 1 Hooks 36 are provided on the front and rear side walls of the material bin 1, and the hook end of each hook 36 is inclined downward; the hooks 36 are provided to facilitate the lifting and transfer of the material bin 1 by the crane.

[0042] Working Principle: In this embodiment, the use of the roadbed slope gully laying equipment is relatively simple and flexible. It only requires finding a transport vehicle that matches the material bin 1. The roadbed slope gully laying equipment is transferred to the transport vehicle's cargo box using a crane. The entire material bin 1 is then erected inside the cargo box using support plates 5. An excavator then feeds materials such as sand and gravel into the material bin 1 from the top port. Under the screening of the feed screen 2, large-diameter fragments are removed, and qualified materials fall into and accumulate in the material bin 1. After filling, the transport vehicle is driven to the construction site. The distance between the transport vehicle and the roadbed is then controlled, and the other end of the chute-type laying plate 7 is positioned in the roadbed gully. Above, the transport vehicle is slowly started, and the conveyor belt 4 is driven by a motor. The conveyor belt 4 conveys the material at the bottom of the material bin 1 to the chute-type material distribution plate 7, and then rolls down into the ditch along the inclined trend of the chute-type material distribution plate 7. The amount of material flowing into the ditch is controlled by the transmission speed of the conveyor belt 4 to ensure that the material flows into the ditch as much as possible, avoiding overflow onto the road surface and causing road pollution, or avoiding scattering outside the roadbed and causing material waste. At the same time, by controlling the first hydraulic cylinder 10, the end height of the chute-type material distribution plate 7 is controlled to realize the parabolic route adjustment of the material, which is flexibly applicable to the indirect connection between the transport vehicle and the roadbed, ensuring that the material falls accurately into the ditch.

[0043] By setting the extension plate 11, the effective material guiding stroke of the chute-type material distribution plate 7 is extended. In some roadbeds where transport vehicles cannot approach, the material can be guided into the ditch by operating the extension plate 11. The second hydraulic cylinder 14 is driven to push the extension plate 11 to extend towards the other end of the chute-type material distribution plate 7, so that the end of the extension plate 11 extends close to the ditch. The material flows along the chute-type material distribution plate 7 onto the extension plate 11, and then rolls from the extension plate 11 into the ditch, thus achieving accurate material delivery.

[0044] When the excavator feeds a bucket of material into the feed screen 2, the material will press down on the feed screen 2 as a whole, which may damage the feed screen 2. To address this, a support assembly is installed. The V-shaped frame 16 and the crossbeam 15 work together to support the screen and withstand greater downward pressure, thus protecting the screen.

[0045] When materials are fed into material bin 1, the materials raise dust and pollute the working environment. To address this, atomizing nozzles 18 are installed. The water mist emitted by the atomizing nozzles 18 suppresses the dust on site and reduces the harm to workers. At the same time, when the materials need to be replenished with water, the water can be sprayed evenly on the materials through the atomizing nozzles 18. This spraying process can also be carried out while the transport vehicle is driving to the construction site, saving time and improving efficiency.

[0046] Before laying materials, the trenches on the roadbed slope need to be cleaned to remove foreign objects. At the same time, the loose soil in the trenches also needs to be hardened to ensure the stability of the base layer. For this purpose, an extrusion roller 22 is installed. The extrusion roller 22 rolls along the trench to compress and harden the loose soil in the trench, so that the trench can be filled in one go when the material is put in later, without the need for secondary material replenishment, saving time and improving efficiency.

[0047] The connecting rod 20 is composed of a fixed base 23 and a rod body 24, which allows the extrusion wheel 22 to swing flexibly. At the same time, the shaft of the extrusion wheel 22 is connected to the slide groove 25 through the compression spring 28, and the extrusion wheel 22 can move up and down with buffer to adapt to the unevenness in the groove and reduce the destructive extrusion of the inner sidewall of the groove on the extrusion wheel 22.

[0048] Water is injected into the hollow extrusion wheel 22 and discharged from the spray hole 29. While rolling, water is drained to moisten the trench, which is suitable for relatively dry areas. It replenishes moisture and causes the powdery material to solidify at the bottom of the trench, compacting the trench.

[0049] When the push rod 33 on the extrusion roller 22 is not pressed against the bottom surface of the groove, water flows out from the spray hole 29 of the push rod 33. The spray hole 29 drains water in an atomized state to reduce dust on the material guided down by the chute-type material distribution plate 7, providing a good working environment for the staff behind the transport vehicle. When the push rod 33 on the extrusion roller 22 is pressed against the bottom surface of the groove, the push rod 33 is compressed into the sleeve 31. Water flows in from the water inlet 34 on the sleeve 31 and is discharged from one end of the sleeve 31. At this time, the water flow is large and can fully wet the inside of the groove, so that the material can fully absorb water and solidify.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
