Definitions

  • the invention relates to an earth working machine having a cutter drum assembly useful in working an earth or road surface.
  • Earth working machines such as self-propelled soil stabilizer machines or roadway resurfacing machines are known. Both the soil stabilizer and the roadway resurfacer employ a horizontal rotor or drum for comminuting and/or mixing soil and other material over which the machine passes.
  • the rotor or drum is provided with a plurality of cutter bits or teeth which are outwardly oriented on the outer periphery of the drum in a form that attempts to provide uniform pulverization or mixing of the ground surface.
  • Such a drum will hereafter be termed a cutter drum.
  • Such earth working machines may be used to dig up and comminute old asphalt or concrete paving which may then be re-applied to the ground to form a suitable foundation for subsequent operations. Comminution of the old surface is necessary to smooth out the surface of the roadway as well as to avoid buildup of the paved roadway to the extent that it overruns the original curbing, gutters or manhole skirts.
  • This was done in a "hot planing" operation in which heaters in front of the earth working machine heated the road surface to reduce the force required of the cutter drum. Because the roadway serves as a heat sink during hot planing, it was determined that hot planing could not be performed on roadways which were quite cold during winter. More recently, "cold planing" has become the preferred mode of operation because, although it requires more cutting power, it does not need a heater and it can be done during any season of the year.
  • the earth working machines may be used as soil stabilizers to blend or mix the soil with suitable additives, such as lime or cement. This produces a hardened or "stabilized” soil which can serve as a base for an asphalt or concrete layer.
  • a road planing apparatus having a plurality of cutter teeth secured on two oppositely directed helical flights is known to the prior art.
  • a number of laterally extending paddle bars are attached between the flights at spaced intervals about the drum near its center portion.
  • the paddle bars are recessed from the cutting heads and serve as scoops to throw the removed paving material cuttings upwardly generally following the drum in its rotary direction.
  • the paddle bars will generally lift the cuttings of the removed pavement material up and over the planing cutter to be received through a passageway onto a material receiving end of a base conveyor so that the material may be conveyed away from the cutting drum.
  • a planer apparatus of this general type is disclosed in United States Patent No. 4,139,318 issued on 13th February, 1979 to Jacob et al.
  • a mining machine having cutter teeth arranged in a continuous helical or scroll pattern in which the two outer teeth of each helix are angled out over a respective side face of the cutter drum at a localized portion of its perimeter is also known to the prior art.
  • a device of this general type is disclosed in United States Patent No. 4,310,199 issued on 12th January, 1982 to Freed et al.
  • a high kinetic energy cutter drum will power through a hard spot in the ground surface rather than being slowed down significantly, or perhaps being stopped altogether as would happen to lower kinetic energy drums.
  • a comparatively high torque motor was used to enable a slow rotating cutting drum to cut through a hard spot in a ground surface.
  • a comparatively high kinetic energy cutter drum is utilized which drum can be powered by a comparatively lower torque motor.
  • the high kinetic energy cutter drum of the present invention can use a far less powerful motor than could the cutter drums of the prior art.
  • the rotational speed of a cutter drum may slow down anywhere from 5% to 20% when the drum encounters obstructions and this greatly decreases its kinetic energy. But if the cutter drum initially has a higher kinetic energy, then its kinetic energy after the obstruction will still be relatively high and it will continue to be able to cut the material.
  • a suitable cutter Since the cutter drum is the part most subject to wear, the frequency and cost of its replacement is a major operating concern for the owners and operators of such equipment. Therefore, a suitable cutter must be capable of removing hard materials, such as concrete, as well as the more elastic materials such as asphalt without needing frequent replacement.
  • each of the teeth will wear faster, less teeth will need to be replaced overall, per mile of roadway cut, than in a design employing more teeth.
  • the cutter drum of the present invention will cut more surface area per number of teeth replaced than the cutter drums of the prior art.
  • an earth working machine for comminuting the upper layer of an underlying surface, the machine having a chassis supported on the surface, characterised by a rotor assembly including a drum rotatably mounted on the chassis with a plurality of cutter bit assemblies secured to the outer periphery of said drum and extending therefrom, and power means operable to rotate said drum at an angular velocity sufficient to create a kinetic energy for the rotor assembly greater than approximately 117 J/cm of drum width.
  • the present invention may be used with a wide variety of earth working machines such as roadway planers, soil stabilizers or cultivating machines of various different configurations.
  • One such soil stabilizer machine is disclosed in United States Patent No. 3,795,279 issued on 5th May, 1974 to Nelson.
  • the machine includes a main frame or chassis 21 having two preferably rubber tired rear traction wheels 23.
  • Two preferably rubber tired steerable front wheels 25 are also provided for the chassis 21.
  • Mounted on the chassis 21 are an internal combustion engine or other suitable power plant 27 and an operator control console 29.
  • An earth working unit 31 is located at the rear of the chassis 21 and is connected thereto by a draw bar 33.
  • the earth working unit 31 may perform the function of comminuting the top surface of a roadway before resurfacing.
  • the earth working unit 31 may be used to mix the top surface of a soil, perhaps with additives, to stabilize the soil.
  • a horizontally disposed cross tube 35 which is rigidly connected to a pair of spaced apart rearwardly extending lifting arms 37 between which a horizontally disposed rotatable cutter drum 39 (not visible in Figure 1, but see Figure 2) is mounted.
  • the cross tube 35 ( Figure 1) is rotatably supported on a support 41 which is secured to the chassis 21.
  • the cutter drum 39 is rotated clockwise as seen in Figure 1 by hydraulic motors 49 which are rigidly mounted on the lifting arms 37.
  • the cutter drum 39 may be raised or lowered by conventional hydraulic actuators (not illustrated) of a suspension system to the desired cutting depth. If desired, the suspension system may also provide for transverse or lateral adjustment of the cutter drum relative to the chassis 21.
  • a screen 61 may also be provided behind the cutter drum 39, if desired, to sweep larger chunks of material back to the drum for further comminution.
  • the cutter drum 39 includes a large tube 70 fabricated by rolling preferably out of a 250mm thick plate of a hard, wear resistant, material. Steel is one example of such a material. Of course, any other material which is able to take the strain of hard wear, and has a high mass density, would also be suitable.
  • the tube 70 is machined down to approximately 190mm thickness in an operation designed to make the outer surface of the tube concentric. In one preferred embodiment, a diameter of 97.5cm is utilized for the tube 70.
  • the tube 70 in the preferred embodiment has a length of 2m.
  • a cutter circle diameter that is the diameter of an imaginary circle to the tip of a cutter 160 of each of a plurality of cutter bit assemblies 100, for the above drum is approximately 1.22m.
  • the tube 70 is provided with a pair of side plates or walls 75 to 0 form the sides of the drum 39.
  • a stub axle 77 is secured to each side plate 75 and extends into a respective roller bearing 79 to rotatably support the cutter drum 39.
  • at least a static balance check is run on the cutter drum 39 to ascertain whether it is balanced and one or more balance weights 81 may be added to the side plates 75, after the cutter bit assemblies 100 have been secured to the drum 39, if necessary.
  • the balance weights 81 compensate for weight unbalances of the cutter drum 39 so that it does not vibrate during its rotation.
  • a total of 154 cutter bit assemblies 100 are preferably provided on a 1.22m cutter circle diameter drum 39.
  • the size of the bit assemblies 100 with respect to the drum 39 in Figure 3 is exaggerated somewhat for clarity. Of course, a larger or smaller number of bits or teeth 160 may be provided on the drum 39 as desired or as found to be advantageous in a particular use of the cutter drum. Naturally, if the cutter circle diameter is different or the drum width is different a different number of bits will have to be used.
  • a plurality of paddles 200 is also provided to displace the comminuted pavement or soil away from the cutter bit assemblies 100.
  • the rotor weldment discloses positions of the paddles 200 and cutter bits 160 around the circumference of the drum 39.
  • 154 bits are provided on the drum 39 although more or less bits may be used as desired or necessitated by circumstances.
  • no less than one bit 160 and no more than three bits are provided on any five degree section of the drum, as evidenced in Figure 4.
  • the bits are placed in a generally random pattern but so that for one rotation of the drum only one bit will cut along each increment of width along the drum while still cutting evenly into the ground surface. Also, the bits are so placed that the rotational balance of the drum 39 is maintained.
  • the cutter drum 39 could be designed to have a cutting circle diameter of 1.5m or larger if so desired.
  • the cutting circle diameter can be reduced to approximately 0.75m or less if desired.
  • the patten of the teeth or cutter bits 160 may vary with the application, the material to be cut or other considerations. Generally, the pattern is subject to three considerations. First, there must be a dynamic balance for the drum 39. Secondly, there should not be any augering of the comminuted material by the cutter bits 160 as this reduces the efficiency of cutting. Thirdly, the number of bits digging at the same time should be limited. The number of bits digging at the same time depends on the depth of cut. With a 2m wide drum and a depth of cut of 36cm, a drum arc of approximately 80 0 (or 20% of the circumference of the drun) will be in contact with the ground surface.
  • the cutting drum 39 is so dimensioned that the cutting points of all of the cutter bits 160 are disposed equidistantly from a rotational axis 95 (see Figure 2) of the drum. This insures that the cutting points define a unifonn line of cutting parallel to the axis of the drum. This uniform line is located at the deepest plane reached in the ground surface by the cutting points as the drum 39 is rotated. The cutting line becomes a cutting plane as the rotating drum 39 is translated forward on the chassis 21.
  • a kinetic energy of at least 20.3kJ may be obtained.
  • the design speed of a 1.22m diameter drum 39 (that is, diameter from cutting tip to cutting tip) is approximately 150rpm plus or minus 10rpm and the designed torque is approximately 8.15 to 9.5kJ. This translates into a kinetic energy of 117 to 410 J/cm of drum width.
  • the kinetic energy to torque ratio (KE/T) will be 4.8 to 1.
  • the KE/T ratio may be anywhere from 3 to 1 to 10 to 1 but is ideally 3.5 to 1 to 5.5 to 1. If the ratio is too high it becomes difficult to manage the cutting operation due to the strains put on the cutter bit assembly. Another problem with a high KE/T ratio is that this means a high impact force for the cutter bits against the surface being cut, which, if the KE/T ratio is too high, will have the dislodged material flying fast enough to injure someone or harm the machine itself. On the other hand, if the KE/T ratio is too low then the cutter drum cannot cut through the hard spots encountered.
  • the cutter drum 39 of the present invention is provided with a high torque which is necessary to deliver a large impact to dislodge or shear tougher material as it is encountered by the cutter bits 160 of the cutter drum. Therefore, the cutter drum or rotor 39 of the present invention has an adequate torque capacity to continuously cut or shear materials from a road bed, for example, and possesses a high enough kinetic energy to dislodge and crush even tougher materials. Such tougher materials are frequently encountered in recycling, planing and soil stabilizing operations.
  • the present cutter drum or rotor 39 therefore possesses a very efficient combination of torque and kinetic energy. This combination of torque and kinetic energy available in the drum 39 means that the cutter bits 160 are provided with high tip velocities and high inertia to velocity changes. Because the cutter drum assembly 39 has a high kinetic energy for pulverizing material, the cutter drum can do rough duty cutting which other cutter drums might find difficult to do, if not impossible.
  • the rotor or cutter drum 39 Due to the high kinetic energy of the rotor or cutter drum 39, it is capable of cutting tougher material than similar comparably powered drums. Since the amount of work done to shear material from a road bed or other ground surface for a fixed rotor width and depth of cut and for a fixed travel distance is a constant, only a minimum amount of energy is expended and hence a smaller motor can be used since a minimum loss of rotor speed occurs.
  • the work done by the rotor may be calculated as a function of the loss of kinetic energy by the drum: If the masses m of the two drums are the same, and if the radii of gyration as well as the tip radii are the same, and for a fixed percent slowdown from initial velocity for each drum then the ratio of work done may be simplified to:.
  • W work done by the drum and where the subscript c is used to indicate the competing drum.
  • ratio of work done varies as the square of the ratio of tip velocities.
  • the ratio of tip velocities for the drum of the present invention to the competing drum is a ratio of two to one the ratio of work done is four to one: If the velocities vary by a ratio of four to one, the ratio of work done varies by sixteen to one:
  • the cutter drum of the present invention may have 617 W/cm of cut but can keep pace with another drum having 1088 W/cm of cut and cut equally tough material.
  • a motor smaller than would be capable of adequately powering the comparison drum will still be able to power the drum 39 of the present invention.
  • the present invention has a cutter assembly weight of approximately 2090 Kg and a cutter teeth tip velocity of 9.6m/s while the comparison drum has a weight of approximately 1525 Kg and a tip velocity of 5.4m/s.
  • the ratio of the impulse forces of the drum of the present invention to a competing drum would then be: where the subscript c represents in each instance the comparison figures for the comparison drum. If the masses are the same and for a fixed percent slowdown in rotor speed of each rotor, the equation may be simplified to: With a ratio of four to one in the velocities of the drum of the present invention to the competing drum, the time duration of the impulses should also vary by a ratio of one to four. That is, the competing drum, since it is only moving at a fourth of the speed of the drum of the present invention, will have a time duration of impulse approximately four times as long. Thus the drum 39 of the present invention will have an impulse force approximately sixteen times the size of the impulse force of the competing drum. When the bits 160 contact the ground surface with a high impulse force, the surface is much more easily comminuted than if it were contacted by the same bit having a lower impulse force.
  • twenty-four of the total number of cutting bits 160 are used on the ends of the drum 39 to reduce the wear on the sides of the drum. These bits 160 also increase the life expectancy of the cutter bit assemblies 100. Twelve bits 160 are located on each end of the drum with the bits 160 being preferably located 30 o apart from each other around the circumference of the drum 39. Of course, the spacing of the angled bits 160 may be varied as is desired.
  • the edge structure of the cutter drum 39 has an upper cutter bit assembly 100 including a cubical bit block pad 110.
  • the bit block pad 110 has a top surface (upon which one bit block or socket 120 is secured) parallel to the bottom mounting surface of the block (as in cutter 100).
  • a second cutter 100' which has an angled bit block pad 112.
  • the angled bit block pad 112 is at approximately 20 0 to 25° angle (as in cutter 100').
  • a third cutter 100" which has a more steeply angled bit block pad 114.
  • the final bit block pad 114 of the group is at a steeper angle of approximately 40° to 45 0 (as in cutter 100").
  • the second cutter bit 160' protects the first cutter bit 160.
  • the third cutter bit 160" protects the second cutter bit 160'.
  • any other suitable angle may also be used as desired.
  • the second cutter bit 100' should only be angled outwardly half as far as the third cutter bit 100" to protect the third cutter bit. If the bits 160 are angled too much, however, they break off during use. On the other hand, if the bits are not angled far enough, the edge bit blocks 120 as well as the edge bit block pads 110, 112, 114 are worn away during the cutting process.
  • the third cutter bit 160" protrudes beyond the surface of a bit pad or socket 120 upon which it is seated and the cutter drum or tube edge itself to relieve the region between the rotating surface and the uncut surface. This improves the life expectancy of the sockets from material washout.
  • the feature of the cutter bits oriented angularly in a progressive fashion of the present invention has been found to be particularly useful in reducing resistance to cutting when making cuts while negotiating turns with the machine. Without the angled cutter bits of the present invention, a conventional cutter drum has difficulty in negotiating turns because the edges of the drum bind against the uncut surface.
  • these three kinds of bit holders are preferably equiangularly positioned around the circumference of the rotor or drum 39 at thirty degree spacing so that four sets of three cutter bits each may be provided at each end of the cutter drum 39.
  • any other sequence of bits may be used as desired.
  • the bit blocks 120 used the edges of the drum 39 are hard faced to minimize the amount of wear on them.
  • the bit blocks 120 used on the main portion of the drum 39, or main blocks, do not need to be hard faced but may be if that is thought desirable.
  • the present positioning of bits 160 on the edge of the cutter drum 39 appears to offer the optimum arrangement for good production and good bit life.
  • bit block pads 110 are secured, for example by welding, to the outer periphery of the cutter drum 39.
  • the bit blocks or sockets 120 are then each secured, for example by welds 170, to the pads 110.
  • the type of bit block 120 which is preferably used in the multi-purpose recycling rotor or drum 39 of the present invention can accommodate two kinds of cutter bits 160.
  • rotating bits 165 provided with a conical carbide tip 180 may be inserted in an opening 140 of each bit block 120.
  • the openings 140 are typically located at a 45° angle to a tangent to the drum 39 periphery at the location of each bit block 120.
  • the center line of the bits 160 are also at a 45° angle.
  • the angle could, of course, be other than 45 0 , that angle has been found to be most advantageous for cutting operations.
  • the rotating bits 165 have a circular body and are thus able to rotate in the bit block 120.
  • a flat bit 167 having a nonrotatably carbide tip 185 may be provided.
  • the flat bit bit 167 is prevented from rotation by the cooperation of a protruding rear extension 168 of the bit 167 with an inner flange or shoulder 150 in the opening 140 of the bit block 120.
  • the rotating bits 165 are useful, preferably, for recycling pavement whereas the flat bit 167 are useful predominately for soil stabilizing operations.
  • bit blocks 120 are angled outwardly from a center line C of the drum 39 (see Figure 3) causes a torque imbalance on the sides of each bit thus causing bit rotation without side load on the machine and the bearings.
  • Such outward orientation or angling from the center line of the drum 39 is approximately 0.5 9 to 2 0 .
  • an angle of approximately 1 0 of outward orientation is used and all the bit blocks 120 on the right of the center line C of the drum 39 (see Figure 3) are angled to the right 1 0 whereas all the bit blocks to the left of the center line C are angled to the left by 10.
  • the cutter drum 39 is provided with a plurality of paddles 200 for moving the dirt or pulverized material away from the cutting surface of the drum 39.
  • twenty-four paddles 200 with approximately two paddles being located along the length of the cutter assembly and placed approximately 20° to 30° apart angularly are provided (see the rotor weldment of Figure 4).
  • more paddles 200 or less may also be found advantageous for some applications.
  • Each paddle 200 is secured immediately in front of a cutter bit block 110, for example by welds 205, to both the bit block as well as to the drum surface.
  • the paddle 200 may be welded to the bit block 110 at an angle in order to decrease the strains on the drum 39 at the weld of the bit block (see Figure 6).
  • the paddles 200 are oriented perpendicularly to the periphery of the drum 39 in order to more easily direct the material away from the drum 39.
  • paddles 200 act to relieve the cutter drum 39 and the cutters 160 by flipping the already cut material over the drum 39 to its back side thus providing for a cleaner cutting action at the shearing plane.
  • the paddles also reduce wear due to the loose material around the bit assemblies 100. It has been found that the placement of paddles 200 around the cutter drum 39 in the preferred embodiment increases production speeds on a given soil or surface by as much as 50% to 100%.
  • the paddles 200 are approximately 152mm long, 13mm wide and 50mm high.
  • the bit block pads 110 may be cubical and approximately 50mm on a side.
  • the bit blocks 120 may be polygonal and approximately 38mm wide and 50mm high and deep. Of course, any other size for the above components may be used as desired. All three, the bit block pad 110 the bit block 120 and the paddle 200 are preferably made of a hard, abrasion-resistant material such as steel.
