Detailed Description

In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

As shown in fig. 1-7, a scraper conveyor for transporting fine powder of a batching system comprises a box body 1 and a conveying chain component, wherein the box body 1 is in a cuboid shell shape, a feed inlet 4 is formed in the upper portion of one end of the box body 1, a discharge outlet 5 is formed in the lower portion of one section of the box body 1, which is far away from the feed inlet 4, of the conveying chain, the conveying chain comprises a chain wheel and a chain, the two chain wheels are respectively arranged at two ends of the box body 1, the chain is wound between the two chain wheels, the chain is formed by connecting a plurality of chain plates 2 in a tail-end mode, a scraper 3 is transversely arranged outside the chain plates 2, the scraper 3 is in a rectangular flat plate shape, the lower side of the scraper 3 is in sliding fit with the bottom surface of the box body 1 when being located at the lower portion of the box body 1, first inclined surfaces are arranged at the upper end and the lower end of one side of the scraper 3, the two first inclined surfaces incline towards the middle of the scraper 3, an included angle alpha is formed between the first inclined surfaces and the bottom surface or the top surface of the scraper 3, and the included angle alpha is not smaller than 55 degrees.
