Description

Technical Field

[0001] The utility model relates to the technical field of rear-dump semi-trailer accessories, in particular to a rear-dump semi-trailer loading and unloading plate. Background Art

[0002] A rear dump trailer is a type of semitrailer specially designed for transporting and dumping various bulk cargoes. Its main feature is that the rear of the vehicle can be lifted by a hydraulic system, so that the cargo can be dumped from the rear end. This design makes the rear dump trailer particularly suitable for the transportation and loading and unloading of materials such as construction materials, ores, sand and gravel.

[0003] When unloading, the existing rear-dumping semi-trailer generally opens the box door to both sides and unloads the goods inside the box by tilting the box body. However, there is a height difference between the box body and the ground during unloading. If some fragile goods fall directly to the ground, the goods are easily damaged, causing cost losses. If a loading and unloading plate is installed after the box door is opened, the unloading efficiency will be reduced.

[0004] Therefore, it is necessary to design a kind of rear unloading semi-trailer loading and unloading plate to solve the problems referred to above. Utility Model Content

[0005] The utility model aims to provide a loading and unloading plate for a rear-dumping semi-trailer, which is used to solve the technical problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] See also Figure 1-4The utility model provides a loading and unloading plate for a rear-unloading semi-trailer, comprising a box body 1 and a rotating plate 2 rotatably mounted on one side of the box body 1, one side of the box body 1 is provided with an opening, the opening is rotatably connected with a rotating shaft 7, the rotating plate 2 is rotatably sleeved on the outer surface of the rotating shaft 7, the top of the rotating plate 2 is provided with an elastic plug-in mechanism, the elastic plug-in mechanism is connected with two symmetrical first plug-in columns 5 and two second plug-in columns 9, and the two first plug-in columns 5 and the two second plug-in columns 9 are slidably inserted in the top of the opening, and the outer surface of the rotating plate 2 is provided with a plurality of device openings 14, and the inner parts of the plurality of device openings 14 are rotatably connected with conveying rollers 6, four card slots 13 are provided on both sides of the outer surface of the rotating plate 2, the outer surface of the rotating plate 2 is slidably sleeved with two symmetrical expansion frames 3, and two symmetrical card blocks 12 are fixedly connected on both sides of the inner cavities of the two expansion frames 3, and the eight card blocks 12 are respectively slidably clamped in the eight card slots 13, and the two first plug-in columns 5 and the two second plug-in columns 9 ... The second plug posts 9 are slidably plugged into the top of the two expansion frames 3 respectively. When transporting goods normally, the two first plug posts 5 and the two second plug posts 9 are slidably plugged into the open top of the box body 1, and the two expansion frames 3 are used to protect the components inside the rotating plate 2 and serve as the box door of the box body 1. When unloading, the two second plug posts 9 and the two first plug posts 5 are separated from the top of the opening through the elastic plug-in mechanism, and the rotating plate 2 and the two expansion frames 3 are rotated. At this time, the rotating plate 2 and the two expansion frames 3 will first contact the ground, and then the two expansion frames 3 will slide out, and the two second plug posts 9 will be slidably plugged into the two expansion frames 3 respectively, so as to limit the sliding position of the two expansion frames 3, and then, the multiple rotating multiple conveying rollers 6 are exposed to the outside. At this time, when the box body 1 is opened and tilted for unloading, the goods will be unloaded under the conveyance of the multiple conveying rollers 6 and the support of the rotating plate 2, thereby avoiding the problem of the box door of the box body 1 being too far away from the ground and the damage of the goods caused by the impact of falling.

[0022] It should be noted that the elastic plug-in mechanism mentioned in the above description includes a sliding plate 17. When the dial plate 4 on one side of the sliding plate 17 is pushed at the operating port 11, the two springs 10 will elastically contract, and the connecting blocks 8 on both sides of the sliding plate 17 will slide inside the two slide grooves respectively, so that the two first plug posts 5 and the two second plug posts 9 will elastically contract, so that the rotating plate 2 and the two expansion frames 3 can rotate at the opening. When the rotating plate 2 is rotated out and the two expansion frames 3 are expanded, the two second plug posts 9 can be slidably plugged with the tops of the two expansion frames 3 through the elasticity of the two springs 10, thereby limiting the expansion position of the two expansion frames 3, thereby facilitating the subsequent unloading of goods.

[0023] In order to enable the two expansion frames 3 to slide smoothly on both sides of the rotating plate 2 and use multiple conveying rollers 6 to unload the goods, multiple arc surfaces are opened on both sides of the inner walls of the two expansion frames 3, and the outer surfaces of the multiple conveying rollers 6 are respectively fitted with the corresponding two arc surfaces.

[0024] Furthermore, in order to ensure stability of the two unfolding frames 3 when sliding, the card blocks 12 are T-shaped blocks, and a plurality of card blocks 12 are slidably disposed in the corresponding card slots 13 .

[0025] Furthermore, when the goods are unloaded, multiple conveying rollers 6 are used to fit the goods respectively, thereby improving the safety of the goods when unloading. The outer surfaces of the multiple conveying rollers 6 protrude from the outside of the multiple device openings 14, and the two expansion frames 3 are both mounted on the outside of the rotating plate 2.

[0026] In order to better utilize the two expansion frames 3 to promote the use of the box door at the opening, and to better limit the sliding position of the two expansion frames 3, the tops of the two expansion frames 3 are both in contact with the top of the opening, and a spacing is set between the bottoms of the two expansion frames 3 and the bottom of the inner cavity of the box body 1, and the tops of the two expansion frames 3 are both provided with a first socket 15 and a second socket 16.

[0027] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0028] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0029] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
