Double portable drive-over hopper
An apparatus includes a first transverse conveyor, first and second pairs of foldable parallel ramps, and first and second foldable longitudinal conveyors. The transverse conveyor moves material in a first direction. The first pair of foldable parallel ramps extend from a first side of the transverse conveyor. The first foldable longitudinal conveyor is positioned between the ramps of the first pair, and is configured to move material toward the transverse conveyor in a second orthogonal direction. The second pair of foldable parallel ramps extend from a second side of the transverse conveyor and are in alignment with the ramps of the first pair. The second foldable longitudinal conveyor is positioned between the ramps of the second pair and is configured to move material in a third direction that is substantially opposite the second direction. |

Bagging mechanism for trash bags and smart trash receptacle
The present invention discloses a bagging mechanism for trash bags and a smart trash receptacle. The bagging mechanism is disposed within a body of the trash receptacle. A first fixed edge and a second fixed edge intersecting the first fixed edge are provided at tops of internal surfaces of the body of the trash receptacle. The bagging mechanism includes a first pressing bar, which is able to slide along the second fixed edge to gather the open end of the trash bag onto the first fixed edge, and a second pressing bar, which is able to slide along the first fixed edge to gather the open end of the trash bag onto the second fixed edge. The first pressing bar and the second pressing bar are further able to work together to gather the trash bag to the intersection of the first fixed edge and the second fixed edge. In the vicinity of the intersection, a heat fusing device is disposed for heat fusing and sealing the trash bag. The bagging mechanism further includes driving means for driving the first pressing bar and the second pressing bar to move. With this arrangement, the issue that conventional smart trash receptacles do not have an automatic bagging mechanism or are only capable of semi-automatic trash bagging, with insufficient bag sealing, insecure sealing and low loading capacity can be solved. |

Portable tank
A tank for bulk material storage and transport and method for producing same. In an embodiment, a tank is provided that includes a shell having a sidewall, a neck including a first collar, and a tube terminating in a second collar. A frustoconical cap may be secured to the first collar. A substantially conical cap may be secured to the second collar. A liner may be applied to the shell so that the liner substantially covers an interior surface of the sidewall, an interior surface of the neck, at least a portion of the first collar, an interior surface of the tube, and at least a portion of the second collar. Annular thickened segments may be trimmed to prepare the tank for use. The annular thickened segments may be located at an interior joint between the frustoconical cap and the first collar, and/or an interior joint between the substantially conical cap and the second collar. The trimming step may form first and second sealing surfaces of the liner adjacent respectively to the first and second collars. The first and second sealing surfaces may respectively be configured to substantially seal against a manway cover and an outlet cover. In a final, assembled preferred form, the frustoconical and substantially conical caps are replaced with the manway assembly and outlet cover, respectively sealed against the first and second sealing surfaces. |
