The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

The nose end of adjusting the middle blind hole in post 13 upper ends has internal thread, and end is connected with driven gear 12, and lower surface is screwed cushion block 11, can stop that driven gear 12 moves down, interchangeable use again after the long-term work wearing and tearing.

The lower end of adjusting lever 1 is a screw mandrel, and the outside is connected with driven gear 2, adjusting lever 1 is threaded whole downforce bar by the lower end screw mandrel with adjustment post 13 blind hole ends.

Two tooth rests, 4 usefulness screws respectively the symmetry, be fixed on the outer surface of frame 24 two sides, adjustment post 13 on the downforce bar is installed in tooth rest 4 middle chambers, the upper and lower of both sides cavity, the gear shaft 10 of vertical mounting strap driving gear 3 and driven bevel pinion 9, the power transmission shaft 6 of horizontal mounting strap driving bevel gear 8 and head sprocket 5, and driving bevel gear 8 and driven bevel pinion 9 engagements, as shown in Figure 1.

Worm screw 31 on the link stopper case 16 on the worm shaft links into an integrated entity with the lower end and worm gear 30 internal threads of the worm gear 30 engagement link stoppers 15 of the interior band of link stopper case inner bolt hole.The end face of link stopper 15 is that circular arc is identical with centering block 14 cooperations and shape, as shown in Figure 4.

On frame 24 bottom surfaces corresponding below each tooth rest 4, be symmetrically fixed with two sprocket holders 18 respectively, sprocket shaft 29 two ends of installing on the sprocket holder 18 are connected with drive sprocket 19, driven sprocket 28, main transmission chain 7 is with head sprocket 5, drive sprocket 19 fuses, on the front surface of link stopper case 16 worm shaft is arranged simultaneously, be connected with two sprocket wheels 17 on the worm shaft, worm gear 30 engagements that worm screw 31 in link stopper case 16 is connected with link stopper 15 lower ends, with driving-chain 21 sprocket wheel 17 on the two link stopper casees 16 is fused, make its energy synchronous operation, with two sections driving-chains 20 sprocket wheel 17 in addition on the link stopper case and the driven sprocket 28 on the sprocket holder 18 are linked into an integrated entity in addition, as Fig. 2, shown in Figure 3.

Power source is motor or handle, and four motors, 27 usefulness screws are installed on the front and back of frame 24, and motor shaft or Handle axis are passed frame 24 and fused with power transmission shaft 6, as shown in Figure 3.

The lower main axis 23 that is connected on the transverse arm 22 is connected with top former seat by top T type coupling block.

During use, according to the size of institute's compacted products, highly, adjust the height of link stopper 15 on the length of downforce bar and the link stopper case.

If the part that the compacting height is short, at this moment need shorten the length of downforce bar, the distance that the piston rod of increase down-pressed pole and band oil cylinder 25 is 26, even motor 27 rotates by power transmission shaft 6 and drives driving bevel gear 8 rotations, make driven bevel pinion 9 rotations simultaneously with its engagement, driven gear axle 10 rotates the driving gear 3 on it, by driven gear 2 adjusting lever 1 that links together with it is rotated with its engagement, the as above identical adjustment post 13 that also makes of another motor 27 rotates simultaneously, at this moment adjusting lever, adjusting post all moves down, the driving-chain 20 that is connected with two driven sprockets 28 meanwhile, the sprocket wheel 17 that drives on the link stopper case 16 outer worm shafts rotates worm screw 31 drive worm gears 30 rotations that make on the worm shaft, with the inner link stoppers 15 that connect of worm gear 30 with to adjust post 13 synchronous but direction is opposite moves upward, reduce the distance of 15 of transverse arm 22 and link stoppers, former is floated in advance and unsteady distance minimizing.

If phase counter regulation, need to increase the length of downforce bar, at this moment need dwindle the distance of 26 in the piston rod of downforce bar and band oil cylinder 25, rotation adjusting lever 1 makes it make progress, adjust post 13 and also makes progress, at this moment link stopper 15 with adjust that post 13 is synchronized with the movement but direction opposite be to move down, the distance of 15 of transverse arm 22 and link stoppers is become greatly, detailed process does not identically repeat with last, former is postponed the distance of floating and float to be increased, the highly bigger part of suitable processing compacting.
