Embodiment 1

[0057] In a typical embodiment of the present invention, such as figure 1 As shown, a bottom-opening open-top box is proposed, which includes a box body and a bottom-opening door, and can transport bulk goods and packaged goods.

[0058] When transporting bulk goods, the opening and closing of the bottom door is used to control the loading and unloading state of the container. When the bottom door is closed, the bottom door can carry bulk goods, and can be loaded and transported; when the bottom door is opened , The material carried by the bottom door panel can slide down along the bottom door panel under the action of gravity, and flow out through the discharge port to realize unloading. When transporting goods, the bottom door is closed and can be used as an ordinary container.

[0059] Wherein, the box body is a cuboid structure, including two side walls 1 arranged in parallel, an end wall 2 arranged at both ends of the two side walls, a bottom frame 3 arranged at the bott...

Embodiment 2

[0098] When transporting goods, it is composed of closing the bottom and opening the door, and the container as a whole is like Figure 1-Figure 3 In the form shown, the goods can be shipped as ordinary open top boxes.

Abstract

The invention discloses a hopper-door-type open top container and a method. The open top container comprises a box body, the top of the box body is open, at least one hopper door assembly is arranged at the bottom of the box body, each hopper door assembly comprises a hopper door plate, one side of the hopper door plate is hinged to the box body, and a bolt assembly is arranged on the other side of the hopper door plate; a lock hook assembly is arranged on the side portion of the box body, and when the hopper door plate is closed, the lock hook assembly and the bolt assembly are clamped to be locked; and the box body is provided with a spring box corresponding to the lower portion of the hopper door, the spring box is obliquely arranged, and when the hopper door plate is opened, the spring box supports the hopper door plate to play a buffering role.

Description

technical field [0001] The invention belongs to the technical field of transportation tools, and in particular relates to a bottom-opening type open-top box and a method thereof. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the bottom-opening open-door cars and funnel cars operating on the railway can carry bulk goods such as coal and minerals, and can realize automatic unloading and easy operation. The transportation scheme of the car has the advantages of one-time loading and multiple transshipment. [0004] The inventors found that the existing common open-top containers are convenient for switching modes of transport in multimodal transport, but unloading needs to be lifted with a forklift or hoisted with a spreader, which requires certain auxiliary facilities. Existing open-top boxes with side-opening doors have the function o...
