Excavator 100 also comprises the large arm 114 that contiguous operator cabin 110 extends from upper frame 102.Arm 114 can be turned around vertical hook by the actuating of a pair arm oil cylinder 116.Dipper arm or arm 118 are rotatably installed in one end place of arm 114, and its position is controlled by oil hydraulic cylinder 122.The end opposite of arm 114 is connected to upper frame 102.The end contrary with arm 114 of dipper arm or arm 118 is mounted to power shovel 124, and power shovel 124 can be rotated relative to arm 118 by oil hydraulic cylinder 120.
The upper frame 102 of excavator 100 comprises the outer housing cover for the protection of engine pack 112.The end contrary with operator cabin 110 of upper frame 102 comprises counterweight 126.Counterweight 126 comprises the housing being filled with material, for increasing weight and the load offset making to collect in bucket 124 of machine.Skew weight can improve the excavation performance of excavator 100.
As shown in Figure 1, first connecting rod 128 and second connecting rod 130 are shown as bucket 124 is connected to oil hydraulic cylinder 120 pivotly.First connecting rod 128 can be called dynamic link.Dynamic link 128 can be connected to the piston rod of oil hydraulic cylinder 120 and be connected to bucket 124 at the second joint 134 place at the first joint 132 place.Second connecting rod 130 can also be connected to dynamic link 128 at the first joint 132 place.In addition, second connecting rod 130 can be connected to dipper arm 118 at the 3rd joint 136 place.When oil hydraulic cylinder 120 controllably moves bucket 124, each in connecting rod 128 and 130 is relative to the first joint 132, second joint 134 and the 3rd joint 136 pivotable.
In multiple routine work machine, work machine as illustrated in fig. 1, joint may need lubrication so that the level and smooth rotary motion of operation period.Therefore, machine can comprise the multiple outer positions about this machine, can be injected in joint area etc. at described outer position place oiling agent.Some in these positions may need daily lubrication.Therefore, flexible pipe or grease gun can be attached to at the external lubrication fat of these position distribute lubricant or " fuel filler neck " type joint.
In many work machines of such as excavator, these external lubrication fat positions are arranged on the position being exposed to dust, sandstone, fragment and other pollutant usually.These positions lower may enter in dust or other material in some cases, make external lug place or neighbouring region be blocked by chip or surround.And in some applications, the mixture that joint may be prevented from the concrete or other type that flexible pipe or grease gun are connected to this joint partly covers.As a result, machine operator or other people may must adopt screw-driver or other instrument unclamp near joints or remove described material.This postpones the time that operator operates machines usually, and in some cases, joint may by described material damage or destruction.
With reference to the machine 100 of Fig. 1, dynamic link 128 may be often towed by dust, sandstone, mud or other material.The external lug being connected to dynamic link 128 may often can be blocked or damage when bucket 124 reduces and enters these materials.Multiple regular machinery is attempted to protect external lubrication joint by being placed on by this joint in the casting region raised or being arranged in the counter sink in the foundry goods of dynamic link 128.Because manufacturing process is simple, multiple in these joints relative to joint axis with 90 ° of orientations.But, the position of these joints and be oriented in operation period and stand pollutant and chip and therefore easily damaged or destroy.
With reference to Fig. 2, show a kind of embodiment of dynamic link 200.Dynamic link 200 can play a role in the mode similar with the first connecting rod 128 in Fig. 1.In other words, dynamic link 200 can comprise first end 202 and the second end 204.First end 202 can be connected to oil hydraulic cylinder 120 at the first joint location 132 place, and the second end 204 can be connected to bucket 124 at the second joint location 134 place.The mode that the first end 202 of dynamic link 200 can limit the first pivot axis 206 with it is connected the first joint location 132 place, and wherein oil hydraulic cylinder 120 and dynamic link 200 are pivoted relative to each other around the first pivot axis 206.Equally, the second end 204 can be connected to the second joint location 134 in the mode limiting the second pivot axis 208, and wherein bucket 124 and dynamic link 200 are pivoted relative to each other around the second pivot axis 208.
