The specific embodiment
Below in conjunction with accompanying drawing embodiment operation principle of the present invention is described in further detail:
Like Fig. 6, Fig. 7, shown in Figure 8: automatic feeding mechanism drive motors 17 passes to down power in the niproll driving shaft 47 through decelerator 14, shaft coupling 15; Following niproll driving shaft 47 passes to down niproll 4 through gear 13 with power; Driving down again, the following niproll belt wheel 5 of niproll 4 one sides rotates; This at present niproll belt wheel 5 drive conveyer belt belt wheels 3 through belt 45 and rotate, thereby conveyer belt 2 is rotated, realize charging.
Like Fig. 4, shown in Figure 9: cut disk-drive motor 41 by cylinder and cylinder cutterhead 20 is rotated, be installed in cylinder and cut the axle that the fly cutter 21 on the dish 20 cuts dish 20 around cylinder and do the circumference cutting thereby drive through the band transmission; Stationary knife 19 is installed on the stationary knife seat 18, and the fly cutter of cutting on the dish 20 with cylinder 21 cooperates, and accomplishes the cut-out to branch.
As shown in Figure 2: cut branch is because the effect of gravity; Enter into primary rotor 23 along blanking plate 22, primary rotor drive motors 25 drives primary rotor 23 through the band transmission and clockwise rotates, and branch is got on the one-level baffle plate 27; Because the gravity effect of branch; Branch can continue to fall to primary rotor 23, after repeating to be crushed to the certain particle size size, falls into the secondary rotor 24 that clockwise rotates that is driven through the band transmission by secondary rotor driven motor 26 again; Because the high speed rotating of secondary rotor 24, force branch to be pulverized at secondary baffle plate 28, three grades of baffle plate 29 bumps; Branch continues to drop into crushing chamber 31 along three grades of baffle plates 29, and the hammer leaf rotor 34 in the crushing chamber 31 is rotation at a high speed under the drive of hammer leaf rotor driven motor 40, and hammer leaf 34 is constantly beaten branch, makes its further pulverizing; Wood materials after the pulverizing is fallen on the fence type sieve 35, and the wood materials after will being pulverized by centrifugal fan 38 is through fence type sieve 35, blanking storehouse 36 and draw 37 discharges of material chamber.Thereby accomplish the whole crushing process of branch.
