The following describes a slope trimming attachment and a working machine of the present application with reference to <FIG>.

As shown in <FIG> and <FIG>, the present embodiment provides a slope trimming attachment. The slope trimming attachment <NUM> includes: a base <NUM>, a first cutting device <NUM>, a leveling mechanism <NUM> and a turning mechanism <NUM>. The first cutting device <NUM> and the leveling mechanism <NUM> are arranged on the turning mechanism14; the turning mechanism <NUM> is rotatably arranged on the base <NUM>, and an angle of the cutting surface of the first cutting device <NUM> relative to the slope surface and an angle of the leveling surface of the leveling mechanism <NUM> relative to the slope surface can be adjusted through rotating of the turning mechanism <NUM>, so that the cutting surface of the first cutting device <NUM> and the leveling mechanism <NUM> have a suitable trimming angle relative to the slope surface to be trimmed.

Specifically, in the present embodiment, the turning mechanism <NUM> is rotatably arranged on the base <NUM>, and the first cutting device <NUM> and the leveling mechanism <NUM> are arranged on the turning mechanism <NUM>, the angle of the cutting surface of the first cutting device <NUM> and the leveling surface of the leveling mechanism <NUM> relative to the slope surface can be adjusted synchronously by the turning mechanism <NUM>, so that when the first cutting device <NUM> performs the cutting operation on the slope surface, the leveling mechanism <NUM> 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 <NUM> and the leveling mechanism <NUM> shown in the present embodiment are arranged on the turning mechanism <NUM>, which can be understood as there are one or more turning mechanisms <NUM>, and each turning mechanism is provided with the first cutting device <NUM> and the leveling mechanism <NUM>, so that the turning mechanism14 can synchronously adjust the angle of the cutting surface of the first cutting device <NUM> and the leveling surface of the leveling mechanism <NUM> 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 <NUM> and the leveling mechanism <NUM> can be arranged on the opposite side of the turning mechanism <NUM> along the second direction, or a plurality of first cutting devices <NUM> can be arranged, and the plurality of first cutting devices <NUM> can be arranged on the opposite side of the turning mechanism <NUM> along the second direction. The leveling mechanism <NUM> is arranged in the middle of the turning mechanism <NUM>, one or more of the leveling mechanisms <NUM> can be arranged in the middle position.

At the same time, the first cutting device <NUM> and the leveling mechanism <NUM> shown in this embodiment are arranged on the turning mechanism <NUM>. It can also be understood that, in the case where a plurality of turning mechanisms <NUM> are arranged to be adjacent, the first cutting device <NUM> is arranged on one of the turning mechanisms, a leveling mechanism <NUM> 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 <NUM> relative to the slope surface and the angle of the leveling surface of the leveling mechanism <NUM> relative to the slope surface can be adjusted respectively.

Obviously, the first cutting device12 and the leveling mechanism13 have other arrangements on the turning mechanism14, which are not listed here.

Furthermore, in the present embodiment, the first cutting device <NUM> and the leveling mechanism <NUM> are detachably connected to the turning mechanism <NUM> respectively in the form of bolt connection or multiple pin connections, so as to ensure the cutting surface of the first cutting device <NUM> and the leveling surface of the leveling mechanism <NUM> have the same orientation when installed on the turning mechanism <NUM>, and are both used to face the slope surface to be trimmed. Since the turning mechanism14 can rotate relative to the base <NUM>, and the first cutting device <NUM> and the leveling mechanism <NUM> are respectively arranged on the turning mechanism <NUM>, with the rotating of the turning mechanism <NUM>, the inclined angle of the cutting surface of the first cutting device12 and the leveling surface of the leveling mechanism13 relative to the horizontal surface also changes accordingly. In this way, the rotating angle of the turning mechanism <NUM> 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 <NUM> cuts the soil at a suitable angle and the leveling mechanism <NUM> compacts the slope surface at a suitable angle, so that the slope surface can be cut at a suitable angle.

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

Thus, in practical applications, the positions of the first cutting device <NUM> and the leveling mechanism <NUM> relative to the slope surface can initially be adjusted based on the turning mechanism <NUM> in the embodiment, and then the inclined angle of the cutting surface of the first cutting device <NUM> and the leveling surface of the leveling mechanism <NUM> relative to the slope surface are finely adjusted respectively based on angle adjustment bracket in order to ensure the accuracy of the slope surface trimming.

The rotating angle of the turning plate <NUM> is adjusted based on the position of the lower end (the end is connected to the connecting plate <NUM>), so that there is a suitable distance and a suitable angle between the turning plate <NUM> and the slope surface to be trimmed. Specifically, the drive assembly <NUM> can drive the lower end of the turning plate <NUM> to a certain position close to the inside of the base11 to adjust the turning plate <NUM> to a proper angle; or, the drive assembly <NUM> can drive the lower end of the turning plate <NUM> to a certain position away from the outside of the base11 to adjust the turning plate <NUM> to a proper angle; or, the drive assembly <NUM> is used to drive the turning plate <NUM> to move relative to the base <NUM> along the first direction.

As shown in <FIG>, the boom <NUM> shown in the embodiment includes a swing arm, a swing arm cylinder, a stick and a stick cylinder; one end of the swing arm and one end of the swing arm cylinder are respectively hinged with the slewing mechanism3, and the other end of the swing arm cylinder is hinged with the middle of the swing arm, the other end of the swing arm is hinged with the first end of the stick, the second end of the stick is hinged with the first hinge point; one end of the stick cylinder is hinged with the middle of the swing arm, and the other end of the stick cylinder is hinged with the third end of the stick. At the same time, one end of the third telescopic drive mechanism <NUM> is hinged with the third end of the stick, and the other end of the third telescopic drive mechanism <NUM> is hinged with the second hinge point. The third telescopic drive mechanism <NUM> is preferably an oil cylinder known in the art.

In the present embodiment, the angle of the swing arm rotation relative to the slewing mechanism <NUM> can be controlled by the swing arm cylinder, the angle of the swing arm rotation relative to the swing arm can be controlled by the stick cylinder, and the angle of the slope trimming attachment <NUM> rotation relative to the stick can also be controlled by the third telescopic drive mechanism <NUM>.

Furthermore, since the boom <NUM> also rotates relative to the walking mechanism <NUM> under the control of the slewing mechanism <NUM>, the position and attitude of the slope repairing accessory <NUM> can be controlled in actual operation under the combined action of the walking mechanism <NUM>, the slewing mechanism <NUM>, the boom <NUM> and the third telescopic drive mechanism <NUM> so as to adapt to the trimming of the slope surface under different working conditions.
