Second is raised corresponding to being provided with, and the second groove engages with the second raised mutually row.Second saw blade top is provided with briquetting, briquetting to
Determine jaw and compress the second saw blade top, the second saw blade bolt, which is fixedly connected on briquetting and is threadedly connected to, determines jaw.Due to the first saw blade
Only by being fixed, top is bolted for bottom, reduces the punching of the first saw blade, can improve the first saw blade
Robustness, rupture is reduced, and dismounted more convenient.Because the second saw blade bottom is only by being fixed, top passes through briquetting
Fixed, punching is less, firmer, is more not easily broken, and dismounts more convenient.
As shown in Figure 1, Figure 2 and Figure 3, sparge pipe for triangular prism shaped water pipe.The cross section of triangular prism shaped water pipe is isosceles
Triangle.First lateral wall of triangular prism shaped water pipe determines jaw towards moving jaw plate, the second lateral wall direction of triangular prism shaped water pipe,
3rd lateral wall of triangular prism shaped water pipe is fixedly connected with the side plate of frame.First hole for water spraying is arranged at the first of triangular prism shaped water pipe
Lateral wall, the second hole for water spraying are arranged at the second lateral wall of triangular prism shaped water pipe.The joint face of triangular prism shaped sparge pipe and frame
Bigger, connection is more firm.It is easy to set hole for water spraying simultaneously, is punched in the lateral wall of triangular prism sparge pipe two, you can is formed towards regulation
The hole for water spraying in direction, without especially calculating angle.In addition, triangular prism shaped sparge pipe is more flat, more smooth, abrasion is less,
Support strength is bigger, broken material environment is more adapted to, service life is longer.Hole for water spraying is water smoke spray orifice, and water smoke spray orifice can be with
Water smoke is sprayed, water smoke penetrability is stronger, is more evenly distributed, and to jaw covering more comprehensively, cooling-down effect is more preferable.Triangular prism shaped water pipe
Tube chamber for cylinder, make water pipe firmer, be not easy to flatten.
