DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The working principle of the present invention will be further described in detail in conjunction with the accompanying drawings:

The motor B (31) drives the primary rotor pulley (54) through the coupling A (55), and transmits the power to the tower pulley group (47) through the ordinary V-belt, thereby driving the roller pulley E (43) Rotate, and the roller pulley E (43) transmits power to the scale drive shaft (56) of the scale conveyor by the V-belt again to drive the scale conveyor to run and realize automatic feeding.

The motor A (58) rotates the drum cutter head through belt transmission, thereby driving the cutting knife installed on the drum cutter head to perform circular cutting around the axis of the drum cutter head; With the cooperation of the knife, the cutting of the branch material is completed.

The cut twig wood enters the impact crushing cavity due to the gravity, and the primary rotor (17) rotates clockwise to beat the twig wood onto the primary baffle plate (19). Due to the gravity of the twig wood, the twig wood will Continue to fall to the primary rotor (17), and after repeated crushing, fall into the secondary rotor (18), due to the high-speed rotation of the secondary rotor, the branch wood is forced to fall on the secondary baffle (20), the tertiary baffle (21) ) between repeated collisions; the branch wood continues to fall into the crushing chamber (23) along the three-stage baffle (21), and the rotor (24) in the crushing chamber (23) rotates at a high speed under the drive of the motor C (59), so that The movable hammer blade (25) continuously beats the branch wood, and continuously staggers with the fixed hammer blade on the arc-shaped fixed hammer plate (26), so that the branch wood with higher toughness is further crushed by shearing; the crushed material passes through the sieve plate Fall into the blanking bin, the branch wood after crushing is discharged by the centrifugal fan (35), thereby complete the whole crushing process of the branch wood.

When the adjustment handle (30) is rotated, the gears in engagement drive the adjustment chute (13) to move to realize the adjustment of the upper feeding roller (6). The adjustment handle (30) is clearance fit with the adjustment handle shaft (46). There is a strip-shaped groove (38) on the shaft, and a key protrusion is arranged on the handle to transmit the torque of the handle. The handle adjustment handle (30) can be adjusted within a certain range. Move back and forth along the groove on the inner shaft. Three cylindrical positioning columns (37) are designed on the side of the handle near the cover plate, and there are nine positioning holes (57) on the equal circumference of the fixed cover plate, which are pressed by the handle. Spring (36) realizes the fixation of adjustment. When adjusting, the handle is pulled out of the positioning hole and the handle is turned to adjust the roller gap.
