Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a disc feeding device for mixing materials comprises a feeding machine main body 1, a coupler 2, a speed reducer 3, a motor 4, a disc 5, scraping pieces 6, a bearing 7, a scraping piece shaft 8, a support 9, a bin wall 10, a scraping plate 11 and a sleeve 11, wherein the output end of the motor 4 is connected with the input end of the speed reducer 3 through the coupler, the output end of the speed reducer 3 is connected with the input end of the feeding machine main body 1 through the coupler 2, the disc 5 is arranged on the output end of the feeding machine main body 1, the bottom of the scraping piece shaft 8 is installed on the disc 5, the top of the scraping piece shaft 8 is fixed through the bearing 7, the bearing 7 is fixed on the support 9, the scraping pieces 6 are fixed on the scraping piece shaft 8, the disc 5, the scraping piece shaft 8 and the scraping pieces 6 can rotate relative to the bin wall 10, the scraping pieces 6 are three in total and are evenly arranged on the scraping piece shaft 8, the positions of the three scraping pieces 6 are staggered and are, the thickness of the scraper 11 is 1cm, the distance between the bottom of the scraper and the disc 5 is 1mm, the scraper is in clearance fit with the wall 10 of the material bin, the shape of the scraper 6 is trapezoidal, and the length of the scraper shaft 8 is three fifths of the radius of the inner wall of the wall 10 of the material bin.

During operation, the disc 5 operates to drive the scraping blade 6 on the scraping blade shaft 8 to rotate, sticky materials on the wall 10 of the bin are cleaned, and meanwhile, the bearing 7 on the upper portion prevents the scraping blade shaft 8 from being eccentric during operation.

Trapezoidal doctor-bar 6 can be effectively scraped the material that is close to silo wall 10 inner wall down, and the gap that leaves between doctor-bar 6 and the silo wall 10 inner wall can reduce motor 4's load, but the distance between doctor-bar 6 and the silo wall 10 inner wall can not be too far away, and too far away can lead to disk feeder's feed volume to hang down, also can lead to the material that silo wall 10 inner wall bonded too much simultaneously.

As can be seen from fig. 4 and 5, when the length of the scraping plate is four fifths of the radius of the inner wall of the silo wall 10, the material conveying amount can reach 80% of the normal state, at this time, the power of the motor is just 100%, if the length of the scraping plate is increased, the motor is overloaded, and the scraping plate at this length can also obtain the highest material power ratio of 0.8, which indicates that the working efficiency is the highest at this time, and the best technical effect can be achieved.

The scraping plate 11 is fixed inside the sleeve 12 and used for removing materials on the circular disc 5, and the materials can be effectively prevented from being adhered to the circular disc 5.

To sum up, this disc feeder for compounding increases scraping device (scraping blade axle and doctor-bar) through on disc feeder's disc, and disc feeder clears up the silo wall in the feed, guarantees the unobstructed of feed bin to ensure that the feed is smooth, production is smooth and easy.
