[0086] Based on the bucket 100 suitable for trapezoidal grooves provided by the present invention, the height of the trapezoidal groove refers to the distance between the bottom plate 111 and the lower surface of the base 2211, the slope of the trapezoidal groove is the same as the inclination angle of the second side plate, and the width of the trapezoidal groove refers to the distance between the two second side plates 114 on a surface parallel to the lower surface of the base 2211.

[0087] First, adjust the height of the trapezoidal groove: By moving the two second side plates 114 upward or downward along the tilt direction of the rotating block 2214, the bottom plate 111 connected to the second side plates 114 moves upward or downward, thereby changing the distance between the bottom plate 111 and the base 2211, and thus changing the height of the trapezoidal groove. Specifically, first remove the fastening plate 133, then rotate the threaded rod 135 to drive the adjustment plate 131 upward or downward along the limit rod 136. When the target height is reached, reinstall the fastening plate 133 and embed the rotating block 2214 in the receiving space 13A. Then, tighten the fastening plate 133 and the adjustment plate 131 with bolts to secure the rotating block 2214. The target height refers to the height of the rotating block 2214 facing the receiving space 13A.

[0088] It should be noted that when the bottom plate 111 moves upward, that is, the second side plate 114 moves upward, at this time, the accommodating space for accommodating the rotating block 2214 also moves upward, and it is necessary to rotate the threaded rod 135 to drive the adjustment plate 131 to move downward, so that the rotating block 2214 faces the accommodating space 13A; when the bottom plate 111 moves downward, that is, the second side plate 114 moves downward, at this time, the accommodating space for accommodating the rotating block 2214 also moves downward, and it is necessary to rotate the threaded rod 135 to drive the adjustment plate 131 to move upward, so that the rotating block faces the accommodating space.

[0089] It should be noted that during the adjustment process, the slide rod can be always connected to the top plate, or the bolts connecting the two can be removed first, the rotating block can be locked, and then the slide rod and the top plate can be connected by bolts.

[0090] Second, the slope of the trapezoidal groove is adjusted, and the height of the trapezoidal groove changes accordingly with the slope adjustment: the rotating block 2214 is rotated about the hinge axis to change the tilt direction of the rotating block 2214, and then the tilt angle of the second side panel 114 is changed so that the second side wall 122 (the tilt angle of the second side panel is the same as the tilt angle of the second side panel) abuts against the surface of the rotating block 2214 opposite the hinge axis. When the target tilt angle is adjusted, the second side panel 114 is locked to the bottom panel 111, and then the top panel 112 is installed. The sliding rod 233 is then slid along the guide groove 232 to connect the sliding rod 233 to the top panel 112. It should be noted that after the tilt angle of the second side panel 114 is changed, the models of the bottom panel 111, top panel 112, first side panel 113, and support partition 116 need to be replaced, that is, different lengths of the bottom panel 111, top panel 112, first side panel 113, and support partition 116 need to be selected for installation.

[0091] Third, adjust the slope of the trapezoidal groove without changing the height of the trapezoidal groove: first change the inclination direction of the rotating block 2214, and then adjust the inclination angle of the second side plate 114 so that the second side wall 122 abuts against the surface of the rotating block 2214. When it is adjusted to the target inclination angle, lock the second side plate 114 and the bottom plate 111, and then install the top plate 112; then drive the adjustment plate 131 to move up or down along the limit rod 136 by rotating the threaded rod 135. When it is adjusted to the target height, install the fastening plate 133 back and embed the rotating block 2214 in the accommodating space, and then lock the fastening plate 133 and the adjustment plate 131 with bolts to fix the rotating block 2214.

[0092] It is understandable that, under normal circumstances, after the slope of the trapezoidal groove is adjusted, the height of the trapezoidal groove will change accordingly. If the height of the trapezoidal groove needs to be kept unchanged, the height of the trapezoidal groove needs to be adjusted.

[0093] The present invention also provides an excavation device suitable for trapezoidal trenches, the excavation device comprising an excavator having a power source, and a bucket 100 detachably connected to the excavator, the bucket being the above-mentioned bucket suitable for trapezoidal trenches.

[0094] In the present invention, the excavator is connected to the excavator connection portion 30 of the bucket 100 .

[0095] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions and substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
