Description

Technical Field

[0001] The utility model relates to the technical field of roadbed processing devices, in particular to a roadbed processing device for road construction. Background Art

[0002] The roadbed, formed by fill or excavation, directly supports the track and is also called the line substructure. The roadbed, connected to bridges and tunnels, together form a line. The roadbed can be divided into embankments and cuttings based on its cross-sectional form. Furthermore, under certain conditions, the natural ground can be used directly as the roadbed surface, without fill or excavation. The materials used to construct the roadbed, whether fill or excavation, are primarily bulk soil and rock. Therefore, the roadbed is a geotechnical structure, and is therefore frequently subject to attack and damage from changes in geological conditions, water, rainfall, climate, earthquakes, and other factors, resulting in poor resistance. Therefore, the roadbed must possess sufficient strength, stability, durability, and reasonable rigidity to ensure smooth and comfortable driving. During roadbed preparation, a layer of waterproof concrete is typically sprayed onto the pavement surface to enhance its smoothness and waterproofness. Currently, the application of waterproof concrete is still performed manually, which is labor-intensive and inefficient.

[0003] A Chinese patent discloses a roadbed treatment device for road construction (publication number CN218116061U). This patent adds waterproof concrete to a barrel, ensures the uniformity of the waterproof concrete under the action of a second drive motor, and avoids the compaction of the waterproof concrete under the action of gravity. During the movement of the mobile trolley, the obstacle clearing plate clears the debris on the roadbed surface to both sides of the mobile trolley, and the discharge valve outputs the waterproof concrete in the barrel to the roadbed surface. The two-way leveling auger rotates to level the waterproof concrete to both sides, and the pressure roller compacts the leveled waterproof concrete. However, in actual road construction, due to the differences in roadbed and road surface, regional differences lead to different soil properties, resulting in the excavated roadbed not being completely suitable for road construction, thereby affecting the quality and service life of the road construction. Therefore, the utility model provides a roadbed treatment device for road construction to solve the above-mentioned problems. Utility Model Content

[0023] Example 1: Please refer to Figure 1 - Figure 5 In the embodiment of the present utility model, a roadbed processing device for road construction includes a discharge hopper 1, a discharge bin plate 2 is fixedly connected to the side of the discharge hopper 1, and the discharge surface of the discharge bin plate 2 is an inclined surface, which can realize the automatic falling of materials and improve the discharge effect. A conveyor belt 24 for conveying materials is provided between the discharge bin plate 2 and the discharge hopper 1. The width of the conveyor belt 24 is the same as the width of the discharge hole at the bottom end of the discharge hopper 1, and the length of the conveyor belt 24 is greater than the length of the discharge hole at the bottom end of the discharge hopper 1, so as to facilitate the transfer of materials in the inner cavity of the discharge hopper 1 into the interior of the discharge bin plate 2, thereby realizing the transmission and unloading of materials. A cleaning mechanism for cleaning the original soil of the roadbed is provided at the bottom of the conveyor belt 24, and moving wheels 3 are provided at both ends of the cleaning mechanism for facilitating the movement of the device.

[0024] See also Figure 3The cleaning mechanism includes two first connecting plates 10, which are fixedly mounted on both sides of the discharge hopper 1. The bottoms of the two first connecting plates 10 are fixedly connected to the second connecting plates 11. A first soil turning block 12 is provided between the two second connecting plates 11. The inner cavity of the first soil turning block 12 is fixedly sleeved with a first rotating rod 14. The first rotating rod 14 is slidably sleeved on the sides of the two second connecting plates 11. Both ends of the first rotating rod 14 are fixedly sleeved with a second soil turning block 13. A second soil turning block 13 is provided on the side of the second connecting plate 11. There is a first sliding groove, and the width of the first sliding groove is the same as the diameter of the first rotating rod 14, so that the first rotating rod 14 can drive the first turning block 12 and the second turning block 13 to move up and down, thereby realizing the turning of the original soil of different thicknesses on the top surface of the roadbed, thereby realizing the renovation of the original soil on the top surface of the roadbed. The first turning block 12 and the second turning block 13 are specifically composed of a rotating drum and a shovel plate. Under the rotation of the first turning block 12 and the second turning block 13, the soil can be turned over, thereby realizing the renovation of the original soil on the roadbed;

[0025] See also Figure 3 The sides of the first turning block 12 and the second turning block 13 are provided with a baffle 8, and a shovel board 15 for shoveling soil is fixedly installed inside the baffle 8. The shovel board 15 is tilted inside the baffle 8 to facilitate the discharge of soil. Both ends of the baffle 8 are fixedly connected with a connecting rod 9;

[0026] Specifically, the baffle 8 is an arc-shaped circular plate, and the diameter of the baffle 8 is larger than the maximum turning diameter of the first turning block 12 and the second turning block 13, so that the turned roadbed original soil can be blocked, the residual rate of the roadbed original soil is reduced, and the paving effect of the new soil is improved;

[0027] See also Figure 3 and Figure 4 The cleaning mechanism also includes two connecting rods 7 fixedly mounted on the side of the first connecting plate 10, the sides of the two connecting rods 7 are fixedly connected to the first support rod 17, the ends of the two first support rods 17 away from the connecting rod 7 are fixedly connected to the second support rod 19, and a connecting frame 18 is fixedly connected between the two second support rods 19. A third connecting plate 4 for connecting the cab is provided on the side of the second support rod 19, and both ends of the third connecting plate 4 are fixedly connected to the sides of the second support rod 19 through connecting columns 16. Under the action of the first support rod 17 and the second support rod 19, the connection and fixing effect of the connecting rod 7 on the discharge hopper 1 can be improved.

[0028] Example 2: Please refer to Figure 1 - Figure 5The second sliding groove is the same length as the first sliding groove opened on the side of the second connecting plate 11, which can facilitate the synchronous movement of the two ends of the first rotating rod 14.

[0029] See also Figure 1 、 Figure 2 and Figure 4 The sides of the two connecting frames 18 are rotatably connected to the first rotating shaft 6, and the two ends of the first rotating shaft 6 are respectively fixedly sleeved on the sides of the two moving wheels 3. Under the action of the first rotating shaft 6, the two moving wheels 3 can be rotated, thereby realizing the movement of the device;

[0030] See also Figure 1 、 Figure 2 and Figure 5 The interior of the conveyor belt 24 is provided with a conveyor roller 23, and a motor 22 is fixedly installed on the side of the discharge hopper 1. The output shaft of the motor 22 is fixedly connected to one end of one of the conveyor rollers 23, and the outer surface of the conveyor belt 24 is fixedly connected with a plurality of pushing plates 25 for pushing the material. A part of the conveyor belt 24 is located inside the discharge bin plate 2, and there is a certain distance between the top of the conveyor belt 24 and the bottom end of the discharge hopper 1. The width of the pushing plate 25 is the same as the contact distance between the discharge hopper 1 and the conveyor belt 24. The two ends of the pushing plate 25 are the same as the width of the conveyor belt 24 and the discharge hole of the discharge hopper 1, which can uniformly convey the material. When the pushing plate 25 is conveyed to the position between the bottom of the discharge hopper 1 and the conveyor belt 24 under the conveyance of the conveyor belt 24, it can play a role in blocking the material inside the discharge hopper 1, thereby realizing the control of material discharge.

[0031] The working principle of the present invention is as follows: when it is necessary to use the device to process the roadbed, first the third connecting plate 4 needs to be connected to the cab so that the device can be moved. Then, according to the processing needs of the roadbed, if the current roadbed needs to be paved with sand and gravel, it is only necessary to move the device so that the sand and gravel inside the discharge hopper 1 can be scattered in the middle part of the roadbed through the discharge bin plate 2, and then the sand and gravel are spread, thereby reinforcing the top surface of the roadbed and thus improving the firmness of the roadbed; if the current roadbed pavement is soft soil that is not easy to compact, it is necessary to clean the current roadbed pavement soil, and then lay soil and sand and gravel that are easy to compact, thereby improving the firmness of the roadbed. At this time, it is necessary to drive multiple cylinders 5 first. The movement of the piston rod of the cylinder 5 can drive the push rod 20 to move, and the movement of the push rod 20 can drive the multiple connecting blocks 21 at its bottom to slide up and down. The sliding of the connecting block 21 can drive the connecting rod 9 and the first rotating rod 14 to move up and down, and then drive the baffle 8, the first turning block 12 and the second turning block 13 to move up and down, so as to adjust the contact distance between the shoveling plate 15, the first turning block 12 and the second turning block 13 and the top surface of the roadbed, thereby increasing the shoveling thickness of the soil on the top surface of the roadbed, and then by moving the device, the device can drive the first turning block 12 and the second turning block 13 to rotate during the movement, thereby realizing the overturning of the soil, increasing the looseness of the soil, and under the overturning action of the first turning block 12 and the second turning block 13, the turned-out soil can be brought into the inner cavity of the baffle 8, and the soil shoveled by the shoveling plate 15 will also enter the inside of the baffle 8, because the bottom of the shoveling plate 15 has the same thickness as the overturned roadbed, thereby improving the shoveling effect of the soil on the top surface of the roadbed, thereby improving the soil cleaning effect;

[0032] Under the blocking effect of the baffle 8, the residual rate of the original soil on the top surface of the roadbed can be reduced. At this time, the motor 22 can be driven, and the rotation of the output shaft of the motor 22 can drive one of the conveying rollers 23 to rotate, thereby realizing the rotation of the conveyor belt 24. Since the outer surface of the conveyor belt 24 is fixedly connected to a plurality of pusher plates 25, the material in the inner cavity of the discharge hopper 1 can be pushed and flow out through the discharge bin plate 2. The outflowing material falls on the top of the cleaned roadbed. At this time, the paved material needs to be spread, thereby realizing the cleaning of the original soil of the roadbed and the replacement of new soil, thereby adapting to the construction needs of the road and improving the strength of the road.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
