Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6 As shown, the utility model provides a roadbed ditch forming device, including a fixing plate 1, a trenching knife 3 and a fixing mechanism. A vertical rod 2 is movably sleeved inside the middle of the top of the fixing plate 1, the bottom of the vertical rod 2 penetrates the fixing plate 1 and extends to the bottom of the fixing plate 1, the inside of the top of the trenching knife 3 is movably sleeved with the bottom of the outer surface of the vertical rod 2, both sides of the top of the inner cavity of the trenching knife 3 are provided with limiting grooves 4, and the fixing mechanism is arranged in the inner cavity of the trenching knife 3. The fixing mechanism includes a driving motor 5, which is fixedly mounted in the middle of the bottom of the inner cavity of the trenching blade 3. The other end of the output shaft of the driving motor 5 is fixedly sleeved with a rotating shaft 6, and the other end of the rotating shaft 6 is fixedly sleeved with a rotating plate 7. Both sides of the rotating plate 7 are hinged with inclined rods 8, and the other end of the inclined rod 8 is hinged with a movable block 9. The outer surface of the movable block 9 is movably connected to the inside of the limiting groove 4. The top of the movable block 9 is fixedly mounted with a clamping plate 10. There are two clamping plates 10. The outer surfaces of the two clamping plates 10 are movably connected to the inner surface of the trenching blade 3. The outer surfaces of the two clamping plates 10 are movably connected to the bottom of the outer surface of the vertical rod 2. The rotation of the rotating plate 7 will cause the two clamping plates 10 to move toward or away from each other. When the driving motor 5 starts to run, the rotating shaft 6 will drive the rotating plate 7 to rotate and the inclined rod 8 to move. At this time, due to the limiting effect of the limiting groove 4, the two movable blocks 9 will drive the two clamping plates 10 to move horizontally toward each other, and finally the trenching blade 3 will be fixed. Similarly, starting the drive motor 5 in reverse will cause the rotating shaft 6 to drive the rotating plate 7 to rotate, and the inclined rod 8 to start moving. At this time, due to the limiting effect of the limiting groove 4, the two movable blocks 9 will drive the two clamping plates 10 to move horizontally in opposite directions, which will release the fixing effect on the trenching knife 3.

[0025] like Figure 2 and Figure 3 As shown, as an optional embodiment, the top of the vertical rod 2 is movably connected to the moving plate 11, the middle of the top of the moving plate 11 is fixedly installed with a first motor 12, the other end of the output shaft of the first motor 12 is fixedly sleeved with a rotating rod 13, the bottom end of the rotating rod 13 passes through the moving plate 11 and extends to the bottom of the moving plate 11 and is fixedly sleeved with the inside of the top of the vertical rod 2. When the first motor 12 starts to run, the rotating rod 13 will drive the vertical rod 2 to start rotating.

[0026] like Figure 4 As shown, optionally, both sides of the rear top of the fixing plate 1 are fixedly connected with a connecting plate 17, a transverse groove 18 is provided at the rear top of the fixing plate 1, a second motor 19 is fixedly installed on the right side of the connecting plate 17, and the other end of the output shaft of the second motor 19 is fixedly sleeved with a threaded rod 20. When the second motor 19 starts to run, the threaded rod 20 will rotate.

[0027] More preferably, Figure 1 As shown, in this embodiment, rollers 24 are movably connected at the four corners of the bottom of the fixed plate 1, and mounting plates 14 are fixedly installed at the front and rear sides of the middle of the top of the fixed plate 1. A vertical slot 15 is provided inside the mounting plate 14, and a fixing block 16 is movably connected inside the vertical slot 15. There are two fixing blocks 16, which are respectively fixedly installed on the front and back sides of the moving plate 11. When the moving plate 11 starts to move, the fixing block 16 will move vertically up and down under the limiting effect of the vertical slot 15.

[0028] More preferably, in this embodiment, the other end of the threaded rod 20 penetrates the connecting plate 17 and extends between the connecting plates 17 and is movably sleeved with the right side of the connecting plate 17. The outer surface of the threaded rod 20 is threadedly sleeved with a moving block 21, and the bottom of the moving block 21 is movably connected to the top of the fixed plate 1. When the threaded rod 20 rotates, the moving block 21 will move horizontally left and right.

[0029] Optional, such as Figure 4 As shown, in the technical solution of this embodiment, a rectangular block 22 is fixedly connected to the bottom of the moving block 21, and the outer surface of the rectangular block 22 is movably connected to the inside of the transverse groove 18. When the moving block 21 moves, due to the limiting effect of the transverse groove 18, the rectangular block 22 will be driven to move horizontally left and right.

[0030] Preferably, a connecting rod 23 is hinged at the top of the moving block 21, and the other end of the connecting rod 23 is hinged to the bottom of the moving plate 11. When the moving block 21 moves, the connecting rod 23 will start to move, so that the moving plate 11 moves vertically up and down.

[0031] From the above content, it can be seen that the technical solution of the utility model has the following effects:

[0032] When trenching is required, the first motor 12 is started, the rotating rod 13 drives the vertical rod 2 to rotate, and the trenching knife 3 starts to rotate. At this time, trenching is carried out. When the height of the trenching knife 3 needs to be adjusted to change the depth of the side ditch, the second motor 19 is started, the threaded rod 20 is rotated, and at this time, under the limiting action of the horizontal groove 18, the movable block 21 drives the rectangular block 22 to move horizontally to the left, and drives the connecting rod 23 to start moving. At this time, under the limiting action of the vertical groove 15, the movable plate 11 drives the fixed block 16 to move vertically downward, so that the vertical rod 2 and the trenching knife 3 move downward together, realizing the function of adjusting the height of the trenching knife 3, improving the application range of the device, and bringing convenience to the operator's trenching operation.

[0033] When the width of the side ditch needs to be changed or the trenching blade 3 is damaged and needs to be disassembled and replaced, the driving motor 5 is started, the rotating shaft 6 will drive the rotating plate 7 to rotate, and the inclined rod 8 will start to move. At this time, due to the limiting effect of the limiting groove 4, the two movable blocks 9 will drive the two clamping plates 10 to move horizontally opposite to each other, and finally the fixing effect on the trenching blade 3 will be released, realizing the function of facilitating the disassembly and assembly of the trenching blade 3, reducing the labor intensity of the operator, and improving the work efficiency of the equipment in replacing the trenching blade 3.
