Apparently, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The following describes a slope trimming attachment and a working machine of the present application with reference to FIGS. 1-3.

As shown in FIG. 1 and FIG. 2, the present embodiment provides a slope trimming attachment. The slope trimming attachment 1 includes: a base 11, a first cutting device 12, a leveling mechanism 13 and a turning mechanism 14. The first cutting device 12 and the leveling mechanism 13 are arranged on the turning mechanism 14; the turning mechanism 14 is rotatably arranged on the base 11, and an angle of the cutting surface of the first cutting device 12 relative to the slope surface and an angle of the leveling surface of the leveling mechanism 13 relative to the slope surface can be adjusted through rotating of the turning mechanism 14, so that the cutting surface of the first cutting device 12 and the leveling mechanism 13 have a suitable trimming angle relative to the slope surface to be trimmed.

Specifically, in the present embodiment, the turning mechanism 14 is rotatably arranged on the base 11, and the first cutting device 12 and the leveling mechanism 13 are arranged on the turning mechanism 14, the angle of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the slope surface can be adjusted synchronously by the turning mechanism 14, so that when the first cutting device 12 performs the cutting operation on the slope surface, the leveling mechanism 13 can also perform the leveling and compaction operation on the slope surface synchronously, so as to realize the trimming of the slope surface.

Therefore, the present application is not only convenient to operate, but also realizes the simultaneous execution of cutting, leveling and compacting operations on the slope surface, improves the construction efficiency of the slope surface trimming, and thereby ensuring the construction quality.

It should be pointed out here that the first cutting device 12 and the leveling mechanism 13 shown in the present embodiment are arranged on the turning mechanism 14, which can be understood as there are one or more turning mechanisms 14, and each turning mechanism is provided with the first cutting device 12 and the leveling mechanism 13, so that the turning mechanism 14 can synchronously adjust the angle of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the slope surface, so that when the cutting surface cuts the slope surface, the leveling surface can compact the slope surface. In a specific embodiment, the first cutting device 12 and the leveling mechanism 13 can be arranged on the opposite side of the turning mechanism 14 along the second direction, or a plurality of first cutting devices 12 can be arranged, and the plurality of first cutting devices 12 can be arranged on the opposite side of the turning mechanism 14 along the second direction. The leveling mechanism 13 is arranged in the middle of the turning mechanism 14, one or more of the leveling mechanisms 13 can be arranged in the middle position.

At the same time, the first cutting device 12 and the leveling mechanism 13 shown in this embodiment are arranged on the turning mechanism 14. It can also be understood that, in the case where a plurality of turning mechanisms 14 are arranged to be adjacent, the first cutting device 12 is arranged on one of the turning mechanisms. a leveling mechanism 13 is arranged on the other turning mechanism, so that through two different turning mechanisms, the angle of the cutting surface of the first cutting device 12 relative to the slope surface and the angle of the leveling surface of the leveling mechanism 13 relative to the slope surface can be adjusted respectively.

Apparently, the first cutting device 12 and the leveling mechanism 13 have other arrangements on the turning mechanism 14, which are not listed here.

Furthermore, in the present embodiment, the first cutting device 12 and the leveling mechanism 13 are detachably connected to the turning mechanism 14 respectively in the form of bolt connection or multiple pin connections, so as to ensure the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 have the same orientation when installed on the turning mechanism 14, and are both used to face the slope surface to be trimmed. Since the turning mechanism 14 can rotate relative to the base 11, and the first cutting device 12 and the leveling mechanism 13 are respectively arranged on the turning mechanism 14, with the rotating of the turning mechanism 14, the inclined angle of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the horizontal surface also changes accordingly. In this way, the rotating angle of the turning mechanism 14 can be controlled based on the inclined angle of the slope surface in the present embodiment, so that the cutting surface of the first cutting device 12 cuts the soil at a suitable angle and the leveling mechanism 13 compacts the slope surface at a suitable angle, so as to facilitate the trimming of the slope surface.

At the same time, in the present embodiment, the first cutting device 12 and the leveling mechanism 13 can also be adjusted separately on the turning mechanism 14, and the inclined angle of at least one of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the turning mechanism can be adjusted.

Here, in the present embodiment, the first cutting device 12 and the leveling mechanism 13 can be respectively installed on the turning mechanism 14 through an angle adjustment bracket known in the art, so that the inclined angle of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the turning mechanism are both adjustable. Thus, in practical applications, the positions of the first cutting device 12 and the leveling mechanism 13 relative to the slope surface can initially be adjusted based on the turning mechanism 14 in the embodiment, and then the inclined angle of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the slope surface are finely adjusted respectively based on angle adjustment bracket in order to ensure the accuracy of the trimming of the slope surface.

It should be pointed out here that the first cutting device 12 described in this embodiment cannot automatically cut the slope surface, but only the slope trimming attachment moves relative to the slope surface when the cutting surface of the first cutting device 12 is adjusted to an appropriate angular position, the first cutting device 12 can realize the cutting and soil removal of the slope surface. Here, the movement of the slope trimming attachment can be driven manually or by a working machine. The first cutting device 12 may be a surface blade, a bucket, a fork-shaped shovel, or a rake-shaped shovel or the like known in the art, which is not specifically limited here.

At the same time, the turning mechanism 14 shown in this embodiment may be a manual adjustment bracket known in the art, or an angle adjustment mechanism driven by a telescopic drive mechanism or a rotary drive mechanism, which is not specifically limited here, as long as the turning mechanism 14 can synchronously adjust the angles of the cutting surface of the first cutting device 12 and the leveling surface of the leveling mechanism 13 relative to the slope surface. One or more of the turning mechanisms 14 shown in this embodiment may be provided. In the case where a plurality of turning mechanisms 14 are arranged, the corresponding rotating axes of at least two turning mechanisms 14 are at a predetermined included angle when rotating, the predetermined included angle is 0°-90°.

In addition, the leveling mechanism 13 shown in the embodiment has a leveling surface, and the leveling surface may be a roller surface or a plate surface. In the case where the leveling surface is the roller surface, the leveling mechanism 13 can realize the compaction and leveling of the slope surface based on the rolling contact between the roller surface and the slope surface; and in the case where the leveling surface is the plate surface, based on the high-frequency vibration of the plate surface relative to the slope surface, the leveling mechanism 13 can realize the compaction and leveling of the slope surface.

Since each turning mechanism 14 is provided with a first cutting device 12 and a leveling mechanism 13. The slope surfaces on both sides of the foundation pit can be trimmed at the same time when the working machine drives the slope trimming attachment 1 to advance along the extension direction of the foundation pit. In the case that the slopes of the slope surfaces on both sides of the foundation pit are different, the turning mechanisms 14 on both ends of the base 11 can be individually controlled to meet the trimming requirements for different slope surfaces.

Furthermore, the first cutting device 12 shown in the embodiment includes a first blade 121, and the first blade 121 is arranged on at least one of the two ends of the turning mechanism 14 in the second direction.

The rotating angle of the turning plate 401 is adjusted based on the position of the lower end (the end is connected to the connecting plate 402), so that there is a suitable distance and a suitable angle between the turning plate 401 and the slope surface to be trimmed. Specifically, the drive assembly 142 can drive the lower end of the turning plate 401 to a certain position close to the inside of the base 11 to adjust the turning plate 401 to a proper angle; or, the drive assembly 142 can drive the lower end of the turning plate 401 to a certain position away from the outside of the base 11 to adjust the turning plate 401 to a proper angle; or, the drive assembly 142 is used to drive the turning plate 401 to move relative to the base 11 along the first direction.

The drive assembly 142 shown in the embodiment includes a first telescopic drive mechanism 411 and a second telescopic drive mechanism 412; one end of the first telescopic drive mechanism 411 (one of the fixed end and the driving end) and one end of the second telescopic drive mechanism 412 (one of the fixed end and the driving end) are rotatably connected to the base 11, the other end of the first telescopic drive mechanism 411 (the other end of the fixed end and the driving end), and the other end of the second telescopic drive mechanism 412 (the other end of the fixed end and the driving end) are rotatably connected to the turning plate 401; the angular position of the connecting plate 402 relative to the base 11 and the angular position of the turning plate 401 relative to the connecting plate 402 can be adjusted through the first telescopic drive mechanism 411 and the second telescopic drive mechanism 412, so that the first cutting device 12 and the leveling mechanism 13 on the turning plate 401 are in a suitable position and the appropriate angle to trim the slope surface.

In a specific embodiment, one end of the first telescopic drive mechanism 411 is rotatably connected to the first position of the base 11, one end of the second telescopic drive mechanism 412 is rotatably connected to the second position of the base 11, and the other end of the first telescopic drive mechanism 411 is rotatably connected to the third position of the turning plate 401. The other end of the second telescopic drive mechanism 412 is rotationally connected to the fourth position of the turning plate 401; the first position is higher than the second position, and the third position is farther from the connecting plate 402 than the fourth position.

In practice, the slope surface shown in the embodiment can be understood as an inclined surface with an acute angle. Based on the configuration of the turning plate assembly 141 and the drive assembly 142, the protrusion extent of the telescopic end of the first telescopic drive mechanism 411 can be controlled to be greater than that of the telescopic end of the second telescopic drive mechanism 412 in the embodiment, the upper end of the flap 401 can be controlled to turn outward when the lower end of the turning plate 401 is at a certain position away from the outer side of the base 11, so that the cutting surface of the first cutting device 12 is inclined downward, the turning plate 121 of the turning plate 401 can cut the inclined surface, and the leveling mechanism 13 on the turning plate 401 performs synchronous leveling on the inclined surface.
