Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

In order to solve the problem that the belt is damaged due to the fact that the coal gangue is difficult to push and forced to push on the conveying bearing piece, the invention designs a novel conveying device on which the coal gangue is sorted. In general, materials are kept in balance under the action of gravity, friction force and supporting force; when the material was discerned for letter sorting target, letter sorting mechanism only need promote, destroys the atress balance, can realize the waste rock letter sorting. The specific scheme is as follows:

referring to fig. 1 and 2, the conveying device provided in this embodiment is used for conveying and sorting materials, and includes a driving unit (not shown), a support frame 10, a plurality of rolling units 20 disposed on the support frame 10, and a conveying carrier 30 laid on the plurality of rolling units 20; a plurality of rolling members 20 for supporting the transport carriage 30, each rolling member 20 preferably being capable of spinning on the support 10; the driving component is connected with the conveying bearing component 30 to drive the conveying bearing component 30 to rotate; the cross-sectional shape of the conveying part (conveying part: the part capable of conveying the carrier 30 at the material bearing part, i.e., the part located at the upper side) of the conveying carrier 30 is entirely high in the middle and low in the two sides. Through the scheme, in the process of conveying materials, the materials are sorted at the conveying part of the conveying bearing piece 30, and the middle of the cross section of the conveying part of the conveying bearing piece 30 is high, and the two sides of the cross section of the conveying part are low, so that the materials can slide off the conveying bearing piece 30 more easily, and a mechanical arm for performing sorting can output small force to push impurities in the materials down to the conveying bearing piece 30 or grab the impurities from the conveying bearing piece 30 to a collecting frame (the collecting frame is used for collecting the impurities in the materials). On the other hand, the frictional force between the foreign substances and the transport carriers 30 is also reduced, thereby reducing the wear on the transport carriers 30.

Wherein, the drive part can be servo motor, and its output shaft connection cylinder, the cylinder directly with carry the cooperation that holds carrier 30 to the realization is carried carrier 30 and is lasted the roll transport material under servo motor's drive. The transport carriers 30 may be conveyor belts, conveyor chains, or the like.

It should be noted that the illustration of fig. 1 is a portion of a delivery device, and is for illustrative purposes only and does not represent a complete delivery device. In which the actual transport carrier 30 is closed, only the transport part on the upper side of the transport carrier 30 is shown in fig. 1, and other parts of the transport carrier 30 and the driving components are all shown, and since these parts are not the modified parts of the present solution, the related structure is not shown, and a detailed description thereof is not given, and the technology in the art can be realized according to the prior art.

In this embodiment, the transported material is coal mixed with coal gangue, and the sorting mechanism needs to sort out the coal gangue from the coal. Coal mixed with coal gangue is conveyed on the conveying bearing piece 30, the coal mixed with coal gangue has a tendency of rolling down on the convex conveying bearing piece 30, but is kept on the conveying bearing piece 30 under the action of friction force, and the sorting mechanism grabs or pushes down the coal gangue in the coal gangue.

Typically, the material is balanced on the transport carrier 30 by gravity, friction and support forces; when the material was discerned for letter sorting target, letter sorting mechanism only need promote, destroys the atress balance, can realize the waste rock letter sorting in pushing away the collection frame with the gangue from the material.

Of course, the transported materials are not limited to coal mixed with coal gangue, all materials with sorting requirements can adopt the transporting device, and the transporting device is particularly suitable for adopting a pull-down sorting method (the pull-down sorting method refers to that the sorted objects on the transporting bearing part are pulled down from the transporting bearing part by external force, and containers can be arranged at the pull-down position for collection).

In particular embodiments, the cross-section of the transport portion of the transport carrier 30 is in the shape of an upwardly convex circular arc, as shown in particular in fig. 3.
