detailed description

The utility model is further described according to the accompanying drawings:

The utility model is a double-knife shaft cutting and crushing device used to replace the picker of a square baler, as shown in Figure 1, mainly connected by a power input shaft (1) and a first-stage gear box (3), and a traction plate ( 2), the primary gear box (3) is connected to the hook frame (5) by bolts. The floating drive shaft (4) is connected to the primary gearbox (3) and the secondary gearbox (9). The secondary gear box (9) is fixed on the double-cutter shaft mechanism (8) by bolts, and the transverse transmission shaft (6) is connected to the secondary gear box (9) and the double-cutter shaft mechanism (8). The double-cutter shaft mechanism (8) is connected to the hitch frame (5) through the floating hitch (7). The power take-off shaft (10) connects the square baler and the primary gear box (3). Lift the floating locking device (11) to connect the hitch frame (5) and the double-cutter shaft mechanism (8). The blower fan (12) is fixed on the hook frame (5) by bolts and is connected with the square baler by a triangle belt. The double cutter shaft cutting and crushing device is connected with the square baler with bolts through the hook frame (5).

Double cutter shaft mechanism (8) structure is shown in Fig. 2,3. The transverse transmission shaft (6) is connected with the first-level driving pulley (14) by bolts, and the first-level driving pulley (14) is connected with the first-level driven pulley (20) by a V-belt. The first-level driven belt pulley (20) is connected with the first-level knife roller (19) by a flat key, and the other end of the first-level knife roller (19) is connected with the secondary driving pulley (18) by a flat key. The secondary driving pulley (18) is connected with the secondary driven pulley (17) by a V-belt, and the secondary driven pulley (17) is connected with the secondary roller (15) by a flat key. Grass storage plate (16) is installed on the cutter shaft support body (13) by bolts.

Fig. 4 is a structural diagram of the floating hitch (7). One end of the boom (21) is connected to the double-cutter shaft mechanism (8) through a pin shaft, and the other end is installed with the hitch frame (5), the outer compression spring (25) and the inner Stage clip (26), spring end cap (27) and T-shaped cover (24) are installed in the spring upper end, thick nut (23) and thin nut (22) are installed in the upper end.
