Description

Wheel rolling type impact compactor of soil

The present invention relates to a kind of wheel rolling type impact compactor of soil, thereby specifically a kind of impact force that constantly produces is more effectively with the device of soil compression in the running of muller.

Existing vibratory roller is that the effect by eccentric shaft of its inside or vibrator produces vibration and comes compacting ground, and its compaction meeting weakens gradually along with the increase of soil depth.Can only reach by the way that increases complete machine tonnage (being static pressure) and corresponding increase exciting force in order to increase compacting depth.And percussion can produce the active force bigger than static pressure to ground, and reach soil layer pressure inside ripple from the surface also darker than the vibration wave of vibratory roller.Normally used drop weight rammer, internal combustion rammer etc. all utilize impact method to come compacting soil.Need to shift work plane but these are mechanical behind compacting one place and just can work on, cause tamping operation not carry out continuously, and the body heaviness, operating efficiency is too low.The non-circular impact road roller of south african patent ZA780537-A is to utilize the change of muller center of gravity in rolling, when the ground connection of its polygonal summit center of gravity is carried to peak, falls under the effect of muller deadweight then and impacts ground.But this device can cause jumping of tractor when impact mass falls, and also can be subjected to the restriction of tractor.Because percussion mechanism is also working on, will smash the road surface of travelling when shifting in the muller strange land, thereby must be with the muller frame on special vehicle frame, thereby make structure complicated.

Purpose of the present invention will solve existing deficiency in the above-mentioned background technology exactly, and provides a kind of and be not subjected to tractor restriction, do not damage the road surface when shifting, can work continuously and novel compaction apparatus that consolidation effect is good.

The technical solution that realizes the foregoing invention purpose is such: this wheel rolling type impact compactor of soil comprises wheel hub, muller, frame and eccentric shaft, it mainly is to be provided with the chute that is made of former and baffle plate between wheel hub and muller, impact block is positioned at chute, has interior raceway and outer raceway on the end plate.The bearing pin at impact block two ends is provided with roller.Form upper shed and under shed between the inside and outside raceway of two symmetries.The top of said outer raceway and the bottom of interior raceway are circular-arc, and the bottom of outer raceway and the top of interior raceway are the straight line formation of joining with circular arc.Baffle plate is provided with slotted eye, and bearing pin and roller exceed the plane of slotted eye.Also can pass through screw one lockplate on baffle plate, the radius of this lockplate semicircular opening is consistent with the radius of lock shaft.End plate is connected with frame by damping block, and the external diameter of end plate is less than the internal diameter of muller.Have bearing between end plate and the wheel hub, also be provided with bearing between wheel hub and the eccentric shaft.

Partial structurtes schematic diagram before Fig. 4: Fig. 2 does not cut open.

Now in conjunction with the accompanying drawings the present invention is described in detail.

As shown in Figure 1, this compacting machine has a frame 1 and muller 2, and eccentric shaft 10 is contained in the wheel hub 9.Design has by former 14 and baffle plate 13 and constitutes the chute 3 that the cross section is a square tube shape between wheel hub 9 and muller 2, and the impact block 4 (referring to Fig. 2) that can be free to slide is housed in the chute 3, and the two ends of impact block 4 respectively are provided with bearing pin 7 and roller 8.An end plate 5 is respectively arranged in the two ends of muller 2, be connected by bearing 12 between this end plate 5 and the wheel hub 9, also be equipped with bearing 11 between wheel hub 9 and the eccentric shaft 10.End plate 5 is fixedlyed connected with frame 1 by snubber block 6.

As shown in Figure 3, the external diameter of end plate 5 is less than the internal diameter of muller 2, on the plane of end plate 5 vertical symmetry be provided with a pair of by interior raceway 17 and outside the raceway formed of raceway 16, leaving between two raceways is enough to upper shed 15 and under shed 18 that impact block 4 is passed through.Wherein, the top of two interior raceways 17 and the bottom of outer raceway 16 are the straight line that the end has radian, and the top of the bottom of two interior raceways 17 and outer raceway 16 is arc.Distance between interior raceway 17 and the wheel hub 9 should guarantee to make the impact block 4 can be by being as the criterion.The roller 8 at impact block 4 two ends rolls with inside and outside raceway 17,16 and contacts.

As shown in Figure 4, baffle plate 13 between two formers 14, leaves the rectangle slotted eye 19 that can expose bearing pin 7 and roller 8 by screw on baffle plate 13, so that roller 8 is bearing on the raceway.Lockplate 20 is fixing with backplate 13 by screw 21, lockplate 20 be provided with one with the identical semicircular opening of bearing pin 7 radiuses.The effect of lockplate 20 be for when the global transfer with impact block 4 lockings and can not in chute 3, be free to slide, thereby can guarantee the excellent of track.

When muller 2 rolled forward or backward, the impact block 4 that is in bottom in the muller 2 upwards promoted (referring to Fig. 2) gradually under the drive of chute 3.After arriving horizontal level, the roller 8 at impact block 4 two ends enters outer raceway 16, because the supporting and the guiding function of outer raceway 16, impact block 4 is remained on the position near muller 2 edges (referring to Fig. 3), and unlikely along chute 3 downslides.When impact block 4 rose to the extreme higher position, the roller 8 that is bearing on the outer raceway 16 entered upper shed 15, and impact block 4 promptly by conducting oneself with dignity along chute 3 free-fallings and impacting on the wheel hub 9, produces the one-shot compaction to surface soil.Meanwhile, raceway 17 in the impact block 4 that was in muller 2 tops originally falls to and enters again behind the wheel hub 9.Because the supporting and the guiding function of interior raceway 17, impact block 4 is remained near on the position of wheel hub 9, and unlikely along chute 3 downslides, when roller 8 enters under shed 18, impact block 4 by conducting oneself with dignity along chute 3 shock of a fall to muller 2, produces the shock compaction effect to surface soil again too.Continuous action so like this can constantly produce the shock compaction effect to surface soil, thereby realizes continuous shock compaction on the basis that circle is ground, and its production efficiency is rammed high more than drop weight rammer, internal combustion, and the consolidation effect in deep then is better than vibratory roller.

This structure can be installed and used with existing vibratory roller is supporting, utilize eccentric shaft 10 or other exciting mode except that producing above-mentioned percussion, also have the vibratory compaction effect, can produce the impact shock compacting simultaneously, further improve compacting efficient surface soil.

When this machine when not working and need the strange land to shift, the semicircular opening of available lockplate 20 is stuck on the bearing pin 7 at impact block 4 two ends, and lockplate 20 usefulness screws 21 are fixed on the baffle plate 13, impact block 4 can be locked in position near wheel hub 9, impact block 4 can not slide along chute 3 in the rotation process of muller 2, so do not produce impact force, thus can road pavement and other plane cause damage.

The present invention has adopted new structure design, utilizes muller impact block motion in chute in rolling process, thereby soil is produced the shock compaction effect, has theoretical and structural breakthrough, embodies shock compaction effect clearly.With also can produce the dual compaction of more superior impact shock after vibratory roller combines, can make simultaneously the traction load of tractor held stationary again, thereby improve its consolidation effect and compacting depth greatly, be applicable to the continuous compacting operation of the desert soil that clay that roadbed, dykes and dams, the water content of high embankment is high and water content are extremely low.Because the design of lockplate can maintain static impact block, can not produce percussion in the transfer process of strange land, can guarantee that the road surface is not damaged.
