Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
In the drawings 1-4, the device comprises a shaft flange 1, a stirring shaft 2, a supporting cross rod 3, a connecting flange 4, a main helical ribbon blade 5, a bottom helical ribbon blade 6 and the like.
As shown in fig. 1-4, the utility model relates to a spiral shell belt stirring rake, including (mixing) shaft 2, the circumferential surface interval arrangement of (mixing) shaft 2 has the support horizontal pole 3 that mutually perpendicular set up, a main spiral shell area blade 5 is drawn forth respectively at the both ends that (mixing) shaft 2 upper portion supported horizontal pole 3, main spiral shell area blade 5 from the last end connection who down supports horizontal pole 3 with each in proper order, and two main spiral shell area blade 5's lower extreme extends to (mixing) shaft 2's lower extreme respectively, bottom spiral shell area blade 6 is connected to main spiral shell area blade 5 bottom surface.
The surface interval of (mixing) shaft 2 is provided with mutually perpendicular's connecting pipe, every the outer end of connecting pipe all sets up flange 4, supports horizontal pole 3 and flange 4 fastening connection.
The fixed axle flange 1 that sets up of upper end of (mixing) shaft 2, at the during operation, (mixing) shaft 2 is connected with external drive shaft through axle flange 1.
The main helical ribbon blade 5 is of a detachable structure, so that the production and the manufacture of the main helical ribbon blade 5 are greatly facilitated, namely, each section of blade can be produced in a segmented mode, and then each section of blade is fastened and connected through a bolt to form the complete main helical ribbon blade 5.
The two main helical blades 5 are symmetrically arranged around the stirring shaft 2, so that the main helical blades 5 can realize a uniform stirring effect when working; the outer spiral line of the bottom helical band blade 6 spirally rises according to the elliptic curved surface of the seal head.
The utility model discloses the product is in concrete production manufacturing process, including several groups and (mixing) shaft 2 welded support horizontal pole 3, support horizontal pole 3 and be the sectional type, through flange, bolted connection, support horizontal pole 3 and be the cross spiral distribution on (mixing) shaft 2. The main helical ribbon blade 5 and the bottom helical ribbon blade 6 are arranged at the front end of the support cross rod 3 through bolts, and two symmetrical helical curved surfaces are formed after the installation.
