The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
The drive principle of the bi-motor drum chipper that provides among the figure as depicted in figs. 1 and 2, is:
Low-voltage driving motor 130,230 drives small belt pulley 120,220 by shaft coupling 121,221 and rotates, belt 122,222 be enclosed within respectively small belt pulley 120,220 and big belt pulley 100,200 on, drive motors 130,230 rotates, drive main shaft 50 and rotate by shaft coupling 121,221, small belt pulley 120,220, belt 122,222, big belt pulley 100,200, and rotate from two ends driven in synchronism cutter drum 60.
As shown in Figure 3 and Figure 4, in cutter drum 60 centers main shaft 50 is installed, stretch out from cutter drum 60 at main shaft 50 two ends, its extension is set with expansion set 111,211, bearing in the bearing block 110,210 is installed on the main shaft 50 by expansion set 111,211 respectively, and main shaft 50 two ends are supported on the support 61 from bearing block 110,210.
Big belt pulley 100,200 respectively key is located at main shaft 50 two ends, be provided with to cutter drum 60 bilateral symmetry drive motors 130,230, this drive motors 130,230 is the 250kW low voltage motor, its drive motors 130,230 output shafts are connected with the belt lace wheel shaft by shaft coupling 121,221 respectively, and building respectively on the cuticle tape spool has small belt pulley 120,220; Belt 122 is on small belt pulley 120 and big belt pulley 100, and belt 222 is on small belt pulley 220 and big belt pulley 200.
As shown in Figure 5 and Figure 6, steelframe pedestal 240 is installed in the outside, cutter drum 60 two ends with steelframe pedestal 140 symmetries; Steelframe pedestal 140 comprises the support 141 of upper end and the pedestal 142 that is arranged on support 141 belows, pedestal 142 fixes with ground, drive motors 130 is installed on the support 141, relative displacement can occur by tensioning bolt 143 with pedestal 142 in support 141, thus the purpose that reaches tensioning or unclamp belt 122.
When actual operation, two drive motors 130,230 of cutter drum 60 both sides turn round simultaneously and drive small belt pulley 120,220, small belt pulley 120,220 drives big belt pulley 100,200 by belt 122,222 respectively and rotates, and rotation direction is shown in the arrow among Fig. 1; Big belt pulley 100,200 driven in synchronism main shafts 50 rotate, thereby band moving knife drum 60 rotates.
Timber enters from the feeding roller 301 of supply transmission system 300 1 sides of equipment, behind the feedstock direction and angle by balance staff 302 adjustment timber, enters cutter drum 60 and cuts.
