Fig. 4 schematically represents one according to impact compactor 10 of the present invention.In this example, main propeller machine of impact compactor 10 usefulness, i.e. tractor 12 tractions, but, should be appreciated that the present invention also can be used for itself just being equipped with the self-propelled impact compactor of main propeller machine.
In the present embodiment, three side compacting weights 14 of structure as impact compactor 10 comprises one to one.Weight 14 is fixedly mounted on the common axis 16, seems on the plane of Fig. 2, and this root common axis has formed the part of tubular axis assembly 18.As shown in Figure 2, tubular axis assembly 18 comprises that 20, pull bars 26 of a pipe are connected on this root pipe.Represent that in the mode of signal above-mentioned pull bar suspension rods 28 of 26 usefulness (Fig. 4) are connected on the vehicle frame 30 that wheel is housed as Fig. 4, vehicle frame then hangs on the tractor 12.
Impact compactor those skilled in the art will be understood that, the structure of towed impact compactor 10 described above is existing.Simultaneously, be further appreciated that thisly to comprise that the traction assembly of pull bar and suspension rod is by flexible, be pulled by soil surface, when being subjected to impact type and hitting, can absorb oscillating load with convenient compacting weight.As want the further details of the traction assembly of this compacting weight of detail knowledge, can consult disclosed content among the patent documentation WO 94/26985.
Abnormal structure of impact compactor 10 is that it has an auxiliary drive.This device comprise one be installed in one with installing plate 33 that above-mentioned pull bar 26 is connected on transfiguration hydraulic motor 32 and a chain and sprocket driving device of in Fig. 4, schematically representing with label 35.See also the more detailed figure among Fig. 1-3, above-mentioned chain and sprocket driving device comprises a sprocket wheel 34 on the output shaft that is installed in motor 32.The chain of schematically representing with a chain-dotted line in Fig. 2 and 3 36 is on sprocket wheel 34, and around being installed on the sprocket wheel 38 of axle on 40.Axle is 40 above axle 16, and is and in parallel, and by the inside and outside bearing 42 on the pipe 20 that is contained in tubular axis assembly 18 and 44 supportings.
