Detailed ways

Example

The straw multi-stage combined grinder of this embodiment, as shown in Figures 1 to 3, includes a casing and a crushing system inside the casing; the crushing system includes a guillotine cutting mechanism and a tooth plate rubbing mechanism arranged in sequence from top to bottom and hammer milling mechanism. the

The casing includes a horizontal cylinder and a vertical cylinder installed on the horizontal cylinder; the guillotine cutting mechanism and the tooth plate kneading mechanism are installed in the vertical cylinder, and the hammer milling mechanism is installed in the horizontal cylinder. the

The guillotine cutting mechanism includes a vertical drive shaft 3, a movable knife 11 arranged on the side of the vertical drive shaft 3, and a fixed knife 10 arranged on the side wall of the casing; The top of axle 3 is fixedly installed on the inwall of vertical cylinder with rolling bearing and upper support, and the bottom end of vertical drive shaft 3 is fixed on the inwall of vertical cylinder by thrust bearing and lower support. the

The toothed plate kneading mechanism includes a cylinder 4 provided with hobbing on the outer peripheral surface and a helical toothed plate 5 arranged on the inner wall of the casing; there is a certain gap between the hobbing teeth and the helical toothed plate 5 . The drum 4 is connected to the vertical drive shaft 3 and rotates coaxially. the

The hammer crushing mechanism includes a horizontal driving shaft 8 arranged horizontally, hammers 6 arranged at intervals on the circumferential surface of the horizontal driving shaft 8, and a sieve plate 13 located below the horizontal driving shaft 8; the sieve plate 13 is evenly distributed with openings. the

A collection box 7 is arranged below the sieve plate 13; a discharge pipeline 9 is provided on one side of the collection box 7; a centrifugal impeller 12 is arranged in the discharge pipeline 9; the centrifugal impeller 12 is connected with the horizontal drive shaft 8 by a coupling and Coaxial rotation. the

As shown in Fig. 3, a feeding mechanism is also provided on the side of the pulverizer; the feeding structure includes a support, and a conveyor belt 16 installed on the support; one end of the conveyor belt 16 is located at the top feeding port 1 of the guillotine cutting mechanism. the

The motor 15 drives the horizontal drive shaft 8 and the centrifugal impeller 12 through the first belt; the motor 15 provides power to the vertical drive shaft 3 and the drum 4 through the second belt 14 and the bevel gear drive. The first belt, the second belt and the bevel gear drive form the transmission mechanism. the

When working, as shown in Figures 1, 2, and 3, the straw is transported to the feed inlet 1 by the conveyor belt 16, and under the negative pressure generated by the rotation of the centrifugal impeller 12 and its own gravity, the straw enters through the feed inlet 1.
