[0002] A discharger is a device used to unload bulk materials. It is usually used in ports, docks, storage facilities and industrial production sites. The function of a discharger is to quickly and efficiently unload bulk materials from a transport vehicle into a designated area or equipment.

[0003] When a gantry unloader with tracks is used to load and unload bulk materials at a dock, the main body of the unloader is mainly used for the transfer of materials, while the tracks are mainly used to adjust the position of the loader. When the tracks are used for walking, the overall volume of the unloader is large, and the overall walking and turning is relatively troublesome. In addition, during the walking process, if there are foreign objects on the ground, the tracks will directly crush them, and some larger foreign objects will block the walking of the tracks. Therefore, it is necessary to design a device that can automatically clean up foreign objects on the walking route. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0019] like Figure 1-4As shown, a gantry crawler unloader proposed by the utility model comprises a gantry pillar 1 and an unloader body 6, an upper end plate 3 is fixed on the upper end of the gantry pillar 1, a pair of walking crawlers 2 are installed at the bottom of the gantry pillar 1, a rotating column 4 is rotatably connected to the upper center position of the upper end of the upper end plate 3, a mounting plate 5 is fixed on the upper end of the rotating column 4, the unloader body 6 is fixed on the front side of the upper end of the mounting plate 5, a unloading grab 61 is installed on the end of the unloader body 6, a lifting hydraulic cylinder 7 is fixed on the four corners of the outer side of the mounting plate 5, and a bottom support seat 71 is fixed on the output end of the lifting hydraulic cylinder 7, the position of the bottom support seat 71 is aligned with the position of the walking crawler 2, a push plate 72 is fixed on the outer side of the bottom support seat 71, a steering assembly 8 is arranged between the upper end plate 3 and the rotating column 4, the horizontal cross-section of the push plate 72 is a triangular structure, and the two sides are inclined surfaces, the rear width of the push plate 72 is greater than the width of the walking crawler 2, and a counterweight is fixedly connected to the rear side of the upper end of the mounting plate 5.

[0020] The steering assembly 8 includes an outer plate 81 and a drive motor 83. The outer plate 81 is fixedly connected to the outer side of the bottom of the rotating column 4. The drive motor 83 is fixed on the upper end plate 3. The output end of the drive motor 83 is located above the outer plate 81 and is fixedly connected to a drive gear 84. An annular gear plate 82 is fixed to the upper end of the outer plate 81, and the annular gear plate 82 is meshed with the drive gear 84. An annular support sleeve 85 is fixedly connected to the upper end of the upper end plate 3. Balls 86 are evenly installed on the upper end of the annular support sleeve 85. The upper end of the ball 86 is abutted against the bottom of the mounting plate 5. The drive motor 83 is used to drive the drive gear 84 to rotate, and then the transmission of the annular gear plate 82 is used to make the upper end plate 3 rotate at the bottom of the rotating column 4.

[0021] In this embodiment, the bottom support seat 71 can be pressed against the ground by the driving of the lifting hydraulic cylinder 7, and the mounting plate 5 can be lifted up, so that the gantry pillar 1 and the walking track 2 are separated from the ground.
