Enter and steel ball structure is installed, steel ball structure can independently be rotated relative to material head is scraped.
As a further solution of the present invention: the steel ball structure includes the big steel ball being placed in stepped hole and two small steel
Pearl, big steel ball are contacted with two small steel balls simultaneously, wherein the surface of two small steel balls exceeds the opening of stepped hole.
As further scheme of the invention: the surface of the scraper plate body is additionally provided with one layer of alloy wear-resisting layer.
A kind of Manufacture method for scrapping plate of coal mine scrapping plate conveyor, comprising the following steps:
S1 using 20CrMnTi steel rolling or forges scraper plate body, rubs in scraper plate body with what intermediate channel or bottom plate were in contact
Surface is wiped, using one layer of alloy wear-resisting layer in the method cladding of plasma cladding；
S2 is later evenly heated scraper plate body by the way of mid-frequency induction heating, immediately after soaks scraper plate body
Enter into NaCl or NaOH aqueous solution, is taken out from solution after cooling；
Then the scraper plate body clear water of taking-up is cleaned and is dried by S3, carry out the assembly of big steel ball and small steel ball, and assembly is completed
The packaging of oiling later.
As a further solution of the present invention: the temperature of step S2 mid-frequency induction heating is 900 DEG C to 920 DEG C.
As the present invention further scheme: the temperature of the NaCl or NaOH aqueous solution is lower than 40 DEG C, and NaCl or
The weight percent of NaOH aqueous solution is 5% to 10%.
Compared with prior art, the beneficial effects of the present invention are: can become sliding friction when steel ball structure and ledge contact
For rolling friction, it can be significantly reduced friction, and by the processing of wearing layer, the service life of scraper plate body can be promoted.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of coal mine scraper conveyer scraper.
In figure: 1- scraper plate body, 2- scrape material head, 3- fixed bolt hole, 4- chain recessing groove, the big steel ball of 5-, the small steel ball of 6-,
7- stepped hole.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
