Description

Technical Field

[0001] The utility model relates to the technical field of slope finishing equipment in earth-moving engineering machinery, in particular to a slope brushing machine. Background Art

[0002] In highway construction, it is often necessary to build slopes. The traditional construction process is generally to measure and mark first and then use an excavator to dig and brush the slope. This working method is extremely inefficient, and there is a risk of overturning when the excavator works on the edge of the slope, which has low safety.

[0003] In the prior art, the utility model patent with the announcement number CN216108550U discloses a mechanical device for brushing the slope of the fill roadbed, which includes a crawler machine and an operating room, a scraper collection box is arranged on the left side of the crawler machine, and two retracting mechanisms are arranged on the rear side of the crawler machine, and the two retracting mechanisms are connected with the same U-shaped plate, a support seat is rotatably installed in the U-shaped plate, and two telescopic motors are rotatably arranged in the U-shaped plate, and the output shafts of the two telescopic motors are both rotatably connected with the bottom of the support seat, and a servo motor is arranged on the support seat, and a reciprocating slide is provided at the bottom of the support seat, and a connecting plate is slidably installed in the reciprocating slide, and a plurality of brush plates are connected to the bottom of the connecting plate, and a scraper is connected to the bottom of the brush plate. In the working state, the reciprocating motion of the connecting plate drives the plurality of brush plates and the scraper to move back and forth, and the brush plates and the scraper perform the slope brushing operation, and the crawler machine brushes the slope while moving forward.

[0004] However, the above structure has the following problems when brushing the slope: the waste generated by brushing the slope is usually piled up on one side of the slope, and finally the waste is transported and processed in a centralized manner after the brushing is completed, which takes a long time and has low work efficiency; the brush plate brushes the slope during the movement of the crawler machine, and the brush plate is only connected to the U-shaped plate, which has poor stability and poor brushing effect.

[0005] The prior art with announcement number CN2828136Y discloses a long slope spiral slope repair machine, including a frame with walking devices at the upper and lower ends adapted to the slope, at least one end of the walking device cooperates with the guide rail, a track is provided on the frame, and a finishing trolley capable of moving on the track is provided on the finishing trolley.

[0006] However, the above structure has the following problems: before the slope brushing construction, it is necessary to lay guide rails on the top and bottom of the slope, and the laying of the guide rails is very time-consuming and labor-intensive, which prolongs the construction period and seriously affects the work efficiency; the frame size of this structure is relatively single, and it cannot be used for slope brushing on slopes with different slope lengths, and it is limited by the connection relationship between the frame and other structural parts arranged thereon, and it is not convenient to simply set the frame as a retractable structure; the transportation and transfer process of this structure is also relatively complicated, and the transfer operation is inconvenient; in addition, this structure also has the problem of being unable to collect waste online.

[0007] The utility model patent with announcement number CN202881905 discloses a new type of long slope slope repairing machine, which is a long slope slope repairing machine integrating roughing, milling, finishing and cleaning processing functions. The machine includes a main frame assembly matched with the long slope, a whole machine walking device, a whole machine lifting device, a cleaning chain bucket device and a milling car. The cleaning chain bucket device includes a bucket and a bucket chain that drives the bucket to move. The bucket body includes a bucket accommodating cavity for accommodating slag and a bucket cap for facilitating the collection of slag. A bucket is installed on the bucket chain at a certain interval. The bucket can move along the bucket guide rail driven by the bucket chain. When it moves to contact the slope, the bucket cap will perform fine-tuning and material-clearing processing on the slope. The machine also includes a slag conveying device located at the lower end of the main frame assembly. The slag conveying device includes a collecting hopper. The bottom of the collecting hopper is provided with a discharge port, and a belt conveyor is provided below the discharge port. When the bucket is turned over by the bucket chain, the slag poured out of the bucket falls onto the conveying belt of the belt conveyor through the discharge port, and is transported to the slag pile by the conveying belt, thereby realizing the functions of slag cleaning and slag transportation.

[0008] However, the above structure has the following problems: in order to ensure the transportation volume of slag, multiple buckets need to be configured, which not only has a complex structure, but also has many parts, which is not conducive to overall storage; the length of the main frame needs to be adapted to the length of the slope, and when it is necessary to brush the slope of different slope lengths, the above structure cannot be applied; in addition, the above structure also has the problem of needing to lay guide rails in advance and inconvenient transportation.

[0056] The lower leg 7 is hinged at the end of the milling support arm 1, and is connected to a leg angle adjustment drive for adjusting the relative angle between the lower leg 7 and the milling support arm 1. The lower leg 7 includes a leg frame 71, a lifting rod 76, and a walking wheel 72 connected to the lifting rod. The lifting rod 76 is connected to the leg frame 71 in a vertical relative sliding connection. A leg frame lifting drive for driving the two to slide relative to each other is connected between the leg frame 71 and the lifting rod 76, and the walking wheel 72 is connected to the lifting rod 76 through a second slewing support 73;

[0057] The milling mechanism 2 includes a milling frame 21 and a milling drum 22. The milling frame 21 is connected to the milling support arm 1 in a manner that it can slide along the length direction of the milling support arm 1. The milling frame 21 is connected to a milling feed drive for driving it to slide relative to the milling support arm 1. The milling drum 22 is rotatably connected to the milling frame 21. The milling drum 22 is connected to a milling drive for driving it to rotate around its own axis. A discharge port 210 is provided on the milling frame 21, and the material produced by the milling drum 22 is discharged through the discharge port 210.

[0058] The first feeding mechanism 3 includes a first conveyor belt 31 disposed at the discharge port, for receiving the material discharged from the discharge port, the first conveyor belt 31 is connected to the milling frame 21, and the conveying direction of the first conveyor belt 31 is the same as the axial direction of the milling drum 22;

[0059] The second feeding mechanism 4 includes a second conveyor belt 41 arranged on the output side of the first conveyor belt 31, which is used to receive the material output by the first conveyor belt 31. The second conveyor belt 41 is connected to the milling support arm 1, and the conveying direction of the second conveyor belt 41 is the same as the length direction of the milling support arm 1.

[0060] Before use, the milling support arm 1 is stored on the traveling frame 100 in the same direction as the traveling frame 100 , and at this time, the upper support articulated frame 6 is connected to approximately the middle position of the milling support arm 1 . Then, the lower wheel body 75 is rotated 90 degrees by controlling the second swivel support 73 so that the travel direction of the lower leg 7 is consistent with the travel direction of the walking frame 100. At this point, the preparations are complete and there is no need to lay the guide rails or do other work.

[0061] When milling and slope brushing, the milling frame 21 is slid to the upper end of the milling support arm 1 and the corresponding slope top position, and then the angle of the milling support arm 1 is adjusted by lifting and lowering the upper support articulated frame 6 and the lower support leg 7 until the milling support arm 1 reaches the predetermined angle and milling depth; the milling feed drive is turned on, and the milling frame 21 moves from the slope top to the slope bottom along the length direction of the milling support arm 2 to perform milling feed work; while the milling frame 21 moves downward, under the drive of the milling drive, the milling drum 22 rotates around its own axis to mill and brush the slope surface; under the action of the milling drum 22, the material produced by milling is discharged through the discharge port and falls onto the first conveyor belt, and the first conveyor belt transports the material to the second conveyor belt perpendicular to it, and finally transports the material to the output side of the second conveyor belt 41, that is, the transport vehicle 200 located above the slope. After the milling frame 21 moves down to the bottom of the slope to complete the milling, the milling mechanism is reset to the top of the slope, and the traveling frame 100 moves forward with the milling support arm 1 as a whole, repeating the above-mentioned milling and brushing action, and so on. When it is necessary to brush the slope multiple times at the same position, without moving the traveling frame 100, repeat the action of resetting the milling mechanism and then moving down to brush the slope. In this way, while achieving milling and brushing the slope, the material can be transported and collected online without the need to set up multiple buckets and other structures. The traveling frame itself has 4 traveling wheels. During the movement of the traveling frame 100, the lower support leg 7 at the bottom of the slope serves as the fifth traveling wheel, and the steering of the lower wheel body 75 during the movement is adjusted by controlling the second slewing support 73 to adapt to the actual working conditions.

Considering that the total weight of the support arm support frame 62 and the milling support arm 1 carried by the upper support bracket 612 is relatively large, two auxiliary lifting cylinders 615 can also be installed between the lower support bracket 611 and the upper support bracket 612, see Figure 7 As shown, the auxiliary lifting cylinder 615 is used to provide an upward supporting force for the upper support bracket 612 when the upper support bracket 612 rises from the lowest state, and helps the support frame lifting cylinder 618 to pass through the initial small arm area. The support frame angle adjustment drive adopts a support frame angle adjustment cylinder 67, and its two ends are respectively hingedly connected between the support bracket 61 (specifically the upper support bracket 612) and the support arm support frame 62.
