Detailed ways

In order to understand the above objects, features and advantages of the present invention more clearly, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the described embodiments are some, but not all, embodiments of the present invention. The specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.

In order to solve the problem that the coal gangue is difficult to push on the conveying carrier and the belt is damaged due to forcibly pushing, a new conveying device is designed in the present invention, and the coal gangue is sorted on the conveying device. Under normal circumstances, the material is kept in balance under the action of gravity, friction and support; when the material is identified as the sorting target, the sorting mechanism only needs to push it to destroy the force balance to achieve gangue sorting. The specific plans are as follows:

1 and 2, the conveying device provided in this embodiment is used for conveying and sorting materials, including a driving part (not shown), a support 10, a number of rolling parts 20 arranged on the support 10, and a plurality of rolling parts 20 laid on the support 10. The conveying carrier 30 on the several rolling elements 20; the several rolling elements 20 are used to support the conveying carrier 30, preferably, each of the rolling elements 20 can rotate on the support 10; The driving component is connected with the conveying carrier 30 to drive the conveying carrier 30 to rotate; the conveying part of the conveying carrier 30 (the conveying part: the part that can carry the material, that is, the part located on the upper side of the conveying carrier 30 ), the overall cross-sectional shape is high in the middle and low on both sides. Through the above solution, in the process of conveying materials, the materials are sorted in the conveying part of the conveying carrier 30 . Since the cross-section of the conveying part of the conveying carrier 30 is high in the middle and low on both sides, the materials are more likely to slip off the conveying carrier 30 , the robotic arm that performs the sorting can output a small force to easily push the impurities in the material down the conveying carrier 30 or grab it from the conveying carrier 30 to the collection frame (the collection frame is used to collect the sundries in the material) . On the other hand, the frictional force between the impurities and the conveying carrier 30 is also reduced, thereby reducing the wear on the conveying carrier 30 .

The driving component may be a servo motor, the output shaft of which is connected to the roller, and the roller directly cooperates with the conveying carrier 30, so that the conveying carrier 30 can continuously roll and convey materials under the drive of the servo motor. The conveyor carrier 30 may be a conveyor belt, a conveyor chain, or the like.
