Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments.
Fig. 1 is a schematic structural view of a rotary arch breaker. This rotatory broken machine of encircleing includes casing 10, casing 20 down, drive assembly 30 sets up between casing 10 and casing 20 down, it bores subassembly 40 to go up to be provided with broken arch in the casing 10, broken arch awl subassembly 40 is connected on drive assembly 30 and is driven and take place to rotate by drive assembly 30, when broken arch awl subassembly 40 rotates, go up casing 10 and casing 20 relatively fixed down, make broken arch awl subassembly 40 at the inside scraping that produces of casing 10, thereby solve the feed bin and block up the knot problem of encircleing.
The driving assembly 30 is installed in the driving chamber between the upper casing 10 and the lower casing 20, and includes a motor 31, a driving gear (not shown in the figure) and a large gear 33, an output shaft of the motor 31 is fixedly connected with the driving gear 32, the driving gear is engaged with the large gear 33, the large gear 33 is coaxially arranged with the upper casing 10, and a hole is formed in the middle of the large gear 33, so that the material can fall down from the middle, and the motor 31 operates to drive the large gear 33 to rotate through the driving gear.
In fig. 2, the arch-breaking awl assembly 40 includes a support frame 41, a central rod 42, a scraper 43 and a blade 44, the support frame 41 is disposed in an opening of the large gear 33 and is fixedly connected with the large gear 33, for example, the support frame 41 can be fixed by welding, the central rod 42 is fixedly mounted on the support frame 41, the scraper 43 is also fixed on the large gear 33, one end of the blade 44 is fixedly connected with the central rod 42, and the other end is fixedly connected with the scraper 43. When the arch breaking cone assembly 40 rotates, the scraping plate 43 destroys the arch forming part in the storage bin and cleans powder adhered on the wall of the storage bin, so that the problem of blocking and forming of the storage bin is solved; the scraper 43 can only clean the powder adhered on the wall of the bin, and the blades 44 can play a role in auxiliary cutting for places with serious arch formation in the bin, so that the problem of blocking and arch formation of the bin is further solved.
In fig. 2, the blades 44 are spaced in the axial direction of the central rod 42, that is, some blades 44 are arranged short, some blades 44 are arranged in the center, and some blades 44 are arranged high, so as to achieve the purpose of performing arch breaking in all directions.
