DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Reference Figure 1-Figure 4 , a trench excavation device for municipal road construction, comprising

[0022] Two main shovel plates 1, an auxiliary shovel plate 2 is slidably connected between the two main shovel plates 1, a connecting seat 3 is fixedly connected to the auxiliary shovel plate 2, an adjusting shaft 4 is rotatably connected to the main shovel plate 1, an adjusting mechanism and a self-locking mechanism are provided on the auxiliary shovel plate 2, and the connecting seat 3 can be connected to the telescopic arm of the excavator for connection work;

[0023] The two adjustment shafts 4 are rotatably connected to a rotating seat at one end away from the main shovel plate 1, and a rotating plate 5 is provided on the auxiliary shovel plate 2;

[0024] The adjusting mechanism includes a threaded rod 6 and a threaded sleeve 7. The threaded rod 6 is rotatably connected to the rotating plate 5. The threaded sleeve 7 is threadedly connected to the threaded rod 6. Two rotating seats are fixedly connected to the two sides of the threaded sleeve 7. By adjusting the spacing between the main shovel plate 1 and the auxiliary shovel plate 2, the overall width of the device can be changed to adapt to trench excavation of different widths. When it is necessary to adjust the distance between the main shovel plate 1 and the auxiliary shovel plate 2, the threaded rod 6 can be rotated to make the threaded sleeve 7 and the two rotating seats move axially along the threaded rod 6, so that the distance between the two main shovel plates 1 and the auxiliary shovel plates 2 can be adjusted.

[0025] The self-locking mechanism includes a limiting cylinder 8, a limiting groove and a sliding paddle 9. The limiting cylinder 8 is coaxially fixedly connected to the threaded rod 6. The limiting groove is provided in the limiting cylinder 8. The sliding paddle 9 is slidably connected to the limiting groove. A reset spring 10 is fixedly connected to the bottom of the limiting groove. The reset spring 10 is fixedly connected to the sliding paddle 9 at one end away from the limiting groove. A self-locking disk 11 is coaxially fixedly connected to the sliding paddle 9. Six positioning holes 13 are provided on the self-locking disk 11. A positioning plate 12 matching the positioning holes 13 is provided on the auxiliary shovel plate 2. The purpose of setting the self-locking mechanism is to lock the angle of the threaded rod 6 to avoid the threaded rod 6 from being locked when the device is in use. When self-rotation occurs and the threaded rod 6 needs to rotate, the self-locking disk 11 can be pressed, and the return spring 10 is compressed. The self-locking disk 11 leaves the positioning plate 12, and the self-locking disk 11 can be rotated. It should be noted that the purpose of setting the limit groove and the sliding paddle 9 is to ensure that the transmission efficiency between the self-locking disk 11 and the threaded rod 6 can be ensured while ensuring the sliding of the self-locking disk 11. When it is rotated to the required angle, the self-locking disk 11 can be released, and the return spring 10 returns to its position, the self-locking disk 11 and the positioning plate 12 are fitted again, and the positioning plate 12 is inserted into the positioning hole 13 on the self-locking disk 11, thereby ensuring the stability of the self-locking disk 11.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] By adjusting the distance between the main shovel plate 1 and the auxiliary shovel plate 2, the width of the entire device can be changed, thereby adapting to trench excavation of different widths. When it is necessary to adjust the distance between the main shovel plate 1 and the auxiliary shovel plate 2, the threaded rod 6 can be rotated to make the threaded sleeve 7 and the two rotating seats move axially along the threaded rod 6, so that the distance between the two main shovel plates 1 and the auxiliary shovel plates 2 can be adjusted;

[0028] The purpose of setting the self-locking mechanism is to lock the angle of the threaded rod 6 to prevent the threaded rod 6 from rotating when the device is in use. When the threaded rod 6 needs to be rotated, the self-locking disk 11 can be pressed. At this time, the return spring 10 is compressed, and the self-locking disk 11 leaves the positioning plate 12. At this time, the self-locking disk 11 can be rotated. It should be noted that the purpose of setting the limit groove and the sliding paddle 9 is to ensure that the transmission efficiency between the self-locking disk 11 and the threaded rod 6 can be ensured while ensuring the sliding of the self-locking disk 11. When it is rotated to the required angle, the self-locking disk 11 can be released. At this time, the return spring 10 returns to its position, the self-locking disk 11 and the positioning plate 12 are fitted again, and the positioning plate 12 is inserted into the positioning hole 13 on the self-locking disk 11, thereby ensuring the stability of the self-locking disk 11.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
