Definitions
- impact roller refers to a compactor mass of non-round shape which, when towed over a soil surface, produces a series of periodic impact blows on the soil surface.
- the compactor mass of an impact roller has a series of spaced apart, salient points on its periphery. Each such salient point is followed by a re-entrant portion of the periphery and each re-entrant portion is followed in turn by a compacting face.
- the impact roller is towed over the soil surface, for instance by means of a tractor, it rises up on each salient point and then falls forwardly and downwardly as it passes over that point, with the result that the following compacting face applies an impact blow to the soil surface.
- the resulting cyclical shock reaction forces on the tractor can cause severe vertical bounce, pitching and rolling of the tractor and compactor mass and consequent damage to mechanical components and discomfort for the tractor operator.
- the depth of the soil indentations and hence the severity of the tractor bounce phenomenon is dependent upon factors such as soil density and moisture content, and energy per impact blow delivered by the compactor mass.
- an impact roller which is coupled resiliently to the carriage for movement with the carriage and which comprises an out-of-round compactor mass adapted to apply periodic impact blows to a soil surface over which it is moved by the carriage, and a soil working implement which is carried by the carriage in a position trailing the impact roller so as to direct soil from the soil surface into localised indentations that are formed in the soil surface by the periodic impact blows applied by the compactor mass.
- the soil working implement is preferably an operatively upright soil working blade arranged to scrape soil into the indentations formed in the soil surface by the blows applied thereto.
- the machine comprises two side-by-side impact rollers, a common shaft on which the impact rollers are mounted for rotation substantially in unison and separate soil working blades carried by the carriage in positions trailing the respective compactor masses.
- the machine may furthermore include lifting and lowering means for lifting and lowering the blades with respect to the soil surface.
- the lifting and lowering means preferably comprises links to which the blades are pivotally connected, a shaft to which the links are solidly connected and one or more hydraulic cylinders acting between the carriage and the shaft, extension or retraction of the cylinder or cylinders causing the shaft and links to rotate and the blades to move up or down.
- Figure 1 shows a partially fragmentary plan view of a soil compaction machine according to the invention.
- Figure 2 shows a part sectional side elevation of the machine seen in Figure 1 with one mass removed so as expose the carriage to view.
- the illustrated soil compaction machine 10 employs two impact rollers or compactor masses 12 located side-by-side in spaced apart relationship.
- Each impact roller 12 is a three-sided roller with three peripherally spaced salient points 14.
- Each salient point 14 is followed, in the direction of rotation of the rollers 12, by a re-entrant portion 16, and each re-entrant portion is followed by a compacting face 18.
- the impact rollers 12 are mounted fast on a common axle 17 in an axle housing 19, so as to rotate substantially in unison when the compaction machine is in operation, as described below.
- a carriage 20 mounted on ground-engaging wheels 22 is located between the impact rollers 12. Pinned at a pivot point 24 to the leading end of the carriage is an upright drop link 26.
- a spring 32 is pivoted between the upper end of the drop link 28 and a clevis 34 at the rear end of a tractor seen partially at 38.
- the spring 32 may be a mechanical or hydraulic spring or, as illustrated, an hydraulically actuated traction rod connected to a gas-filled accumulator 71 so as to provide required load-deflection characteristics.
- the linkage between the carriage 20 and the impact rollers 12 is resilient in nature.
- the tractor 38 travels forwardly in the direction of the arrow 39 and pulls the carriage 20 and the impact rollers 12 behind it.
- the impact rollers 12 rotate in unison with one another.
- the mass rises up on a salient point 14 then, once an over-centre condition is reached, drops downwardly and forwardly for the following compacting face 18 to impact against the soil surface.
- the impact blows applied to the soil surface by the impact roller typically result in the creation of indentations 40 such as that seen in Figure 2.
- each soil working system 42 includes a blade 44 which lies in a generally upright plane and which has a length corresponding to the tread width of the associated impact roller.
- Links 46 are provided with several hole positions 47 about any chosen one of which the upper edge of the blade 44 can be pivoted.
- the link 46 is connected fast to a shaft 48 common to both blades 44.
- Double acting hydraulic rams 50 are connected pivotally between clevises 52 on the carriage and clevises 54 which re connected solidly to the shaft 48.
- the arrangement of links 46, shaft 48 and clevises 54 constitutes a bell-crank mechanism operating to raise or lower the blade relative to the soil surface 15 according to whether the rams 50 are retracted or extended.
- each of the two hydraulic rams 50 can operate upon a separate, rotatable shaft so as to enable the blades to be operated independently of the other.
- the rams 50 and 56 are controlled from an operator station (not shown) on the tractor 38 through hydraulic circuitry which is omitted from the Figures in the interests of clarity but the nature of which will be readily apparent to those skilled in the art.
- the blades 44 may be provided with replaceable cutting tips.
- a water spray head 60 fitted with spray nozzles 62 is mounted on each blade as illustrated.
- the spray head is supplied with metered amounts of water under gravity or under pressure from a water tank 64, mounted on the carriage, via hoses 66.
- the spray heads spray water onto the soil surface 15 behind the impact rollers and ahead of the blades 44.
- the blades then cut through the high points 36 of the moistened soil surface and move the cut soil forwardly into the previously formed indentations 40.
- a further advantage of the machine as described above is the fact that the watering of the soil surface is localised in the areas where soil working and compaction are actually taking place. Thus there is a reduced water consumption compared to the current system where generalised soil watering takes place.
- the fact that the water tanks add mass to the carriage and impact roller structure is not considered to be a major drawback since it is, in any event, common practice to ballast the machine to improve its traction on the soil.
