Description

Technical Field

[0001] The utility model relates to the field of loaders, in particular to a bucket mounting structure, a bucket arm and a loader. Background Art

[0002] In road construction, especially in high-grade highway construction, loaders are used for filling and excavation of roadbed engineering, collection and loading of asphalt mixture and cement concrete material fields, etc. In addition, they can also carry out operations such as pushing soil, leveling the ground, and pulling other machinery. At present, the bucket of the loader is usually directly connected to the rocker arm by a pull rod. When shoveling materials with poor fluidity, it will not be able to unload cleanly due to the small discharge angle; when flattening the materials after loading, it will not be able to push to the edge of the car body due to the insufficient discharge angle.

[0025] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0026] Embodiment 1:

[0027] In a typical embodiment of the present invention, Figure 1 and Figure 2 As shown, a bucket mounting structure is provided.

[0028] Due to the method of connecting the bucket by a pull rod in the prior art, the tooth tip of the bucket cannot reach the inner edge of the carriage, resulting in an inability to unload the materials cleanly and to push the materials to the inner edge of the carriage; based on this, the present embodiment provides a bucket mounting structure, including a bucket 1, a rocker arm 3, a boom 2, a slide 4, and a slide rod 5. The slide rod 5 and the slide 4 form a telescopic mechanism, which replaces the existing pull rod structure and can increase the overall angle of the bucket 1.

[0029] Specifically, Figure 1 and Figure 2 As shown, one end of the boom 2 is hinged to the back side of the bucket 1, the rocker arm 3 is hinged to the boom 2, and there is a certain distance between the rocker arm 3 and the bucket 1. The slide bar 5 is slidably connected to the slide 4, and a hinge support is installed in the middle position of the back side of the bucket 1. One end of the slide bar 5 is hinged to the hinge support, and the other end of the slide bar 5 is connected to the movable end of the cylinder 6. The fixed end of the cylinder 6 is connected to the rocker arm 3. At the same time, the slide 4 is hinged to the rocker arm 3; the slide bar 5 is driven to move relative to the slide 4 by the extension and contraction of the cylinder 6, thereby changing the angle of the bucket 1. Compared with the case where the angle of the bucket 1 is changed only by the pull rod, this embodiment can increase the discharge angle.

[0030] The slide bar 5 and the slide frame 4 only need to ensure relative sliding. Figure 3 and Figure 4 As shown, a slide rail 43 is installed on the inner wall of the slide 4, and a pin 7 is installed on the slide bar 5. The setting direction of the pin 7 is perpendicular to the moving direction of the slide bar 5. Both ends of the pin 7 extend out of the side wall of the slide bar 5 so as to overlap the upper side of the slide rail 43. One or more pins 7 can be arranged along the sliding direction of the slide bar 5. Since the cross section of the pin 7 is circular, it is in point contact with the upper surface of the slide rail 43, which can reduce the friction of the relative sliding between the two, thereby reducing the resistance during angle adjustment.

[0031] In this embodiment, if Figure 5 As shown, the cross section of the sliding rod 5 is rectangular, and its main body is a box-type structure to ensure the connection strength.

[0032] like Figure 4As shown, the slide 4 includes a bottom plate 42 and two side plates 41, and the two side plates 41 are symmetrically mounted on both sides of the bottom plate 42, and the side plates 41 are perpendicular to the bottom plate 42. A slide rail 43 is fixed to the inner wall of each side plate 41, and the slide rail 43 is arranged along the length direction of the side plate 41, and the length of the slide rail 43 is less than the length of the side plate 41. The length of the bottom plate 42 can meet the travel of the slide rod 5.

[0033] A sleeve is provided at one end of the inner side of the side plate 41 , and a pin is installed through the sleeve to realize hinge connection with the rocker arm 3 .

[0034] In this embodiment, the pull rod is adjusted into two parts, the slide 4 and the slide rod 5, on the basis of the original connecting rod mechanism. The length of the slide rod 5 relative to the slide 4 can be changed by extending and retracting the cylinder 6, thereby increasing the unloading angle of the loader at any position during the entire operation process, which can make the material unloading cleaner and also increase the flattening range.

[0035] Embodiment 2:

[0036] This embodiment provides a bucket arm, including an arm frame, and the arm frame is equipped with the bucket mounting structure described in the first embodiment.

[0037] Embodiment three:

[0038] This embodiment provides a loader equipped with a bucket arm as described in the second embodiment. The loader can be applied to two working conditions, one is unloading and the other is spreading the material. There will be no situation where the unloading is not clean or the material cannot be pushed to the edge of the carriage when it is spread.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
