[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a stabilizing mechanism for a small excavator, including an excavator body 1, which is a small excavator. Stabilizing mechanisms are provided on the left and right sides of the rear of the excavator body 1, which are used to improve the stability of the excavator. The stabilizing mechanism includes a mounting plate 2, which can be fixed to the excavator body 1 by bolts, etc., and mounting frames 3 are provided on the upper and lower parts of the side of the mounting plate 2 away from the excavator body 1, which are used to cooperate and connect various components. A No. 1 cylinder 4 is provided in the middle of the side of the mounting plate 2 away from the excavator body 1, which is used to control the use and retraction of the support assembly 5. A support assembly 5 is commonly provided between the two mounting frames 3, which is used to improve the stability of the excavator.

[0031] like Figure 3 - Figure 4As shown, the support assembly 5 includes a support leg 51, which is used for support. The bottom of the support leg 51 is fixedly connected to a support plate 52, which is circular and is used for support to improve the stability of the excavator. The interior of the support leg 51 is provided with a fixing part for further stabilizing the excavator on uneven ground. The fixing part includes a No. 2 cylinder 53, and the bottom of the No. 2 cylinder 53 is fixedly connected to a fixing cone 54, which is used to penetrate into the ground to improve the stability of the support assembly 5. An installation cavity 511 is provided inside the support leg 51, which is used to cooperate with the fixation of the No. 2 cylinder 53. The No. 2 cylinder 53 is fixedly connected to the top of the inner wall of the installation cavity 511, and an auxiliary port 521 is provided in the middle of the support plate 52 for cooperating with the use of the fixing cone 54.

[0032] Furthermore, the upper and lower left and right sides of the side of the mounting plate 2 away from the excavator body 1 are fixedly connected with connecting blocks 21, which are used to cooperate with the connection of the mounting frame 3. The lower part of the side of the mounting plate 2 away from the excavator body 1 is fixedly connected with a connecting seat 22, which is used to cooperate with the connection of the No. 1 cylinder 4. The No. 1 cylinder 4 is movably connected with it. The output end of the No. 1 cylinder 4 is movably connected with a gas rod 41, which is used to cooperate with the connection of the support leg 51. The gas rod 41 is movably connected to the upper part of the support leg 51 on the side away from the mounting plate 2.

[0033] Furthermore, the side of the mounting frame 3 close to the excavator body 1 is movably connected to the connecting block 21, which is used to cooperate with the connection of the mounting frame 3. The side of the upper mounting frame 3 close to the support leg 51 is penetrated and rotatably connected with a connecting rod 31, which is used to cooperate with the connection of the upper mounting frame 3 with the gas rod 41 and the support leg 51 bracket. The connecting rod 31 penetrates the gas rod 41 and the support leg 51 and is rotatably connected to the gas rod 41 and the support leg 51. The front and rear parts of the inner wall of the side of the lower mounting frame 3 close to the support leg 51 are fixedly connected with a protruding rod 32, which does not penetrate the support leg 51 and is used to cooperate with the connection of the support leg 51. The protruding rod 32 is rotatably connected to the support leg 51.

[0034] Working principle: When in use, open the No. 1 cylinder 4, the gas rod 41 of the No. 1 cylinder 4 will move accordingly, and the mounting frame 3 and the support leg 51 connected to the gas rod 41 through the connecting rod 31 will be driven accordingly. At this time, the mounting frame 3 on the stabilizing mechanism on both sides of the excavator will be driven by the No. 1 cylinder 4 and spread to both sides, thereby driving the support leg 51 to move toward the ground until the support leg 51 drives the support plate 52 to support on the ground. At this time, the stabilizing mechanism on both sides of the excavator will be fully opened to provide support for the small excavator. When the support mechanism is not needed, it is only necessary to control the gas rod 41 through the No. 1 cylinder 4 again. Move in the opposite direction. At this time, the gas rod 41 will drive the mounting frame 3 and the support leg 51 connected thereto to be retracted through the connecting rod 31, so that the support mechanisms on both sides are folded up. When the ground is uneven and the support provided by the support plate 52 is not stable enough, the No. 2 cylinder 53 can be opened, and the No. 2 cylinder 53 will push the fixed cone 54 to move downward, so that the fixed cone 54 protrudes from the auxiliary port 521 and is inserted into the ground, thereby further enhancing the support stability of the stabilizing mechanism. When the fixed cone 54 is not needed, it is only necessary to drive the fixed cone 54 to be retracted through the No. 2 cylinder 53 so that the fixed cone 54 is completely retracted into the mounting cavity 511.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
