A vehicular automotive soil treating machine having a main frame structure provided on an automotive drive means to support thereon a soil feeding stage including at least a soil hopper and an additive hopper, a soil processing stage including a soil processing trough which is internally provided with a mixing means for mixing soil and additive material while being transferred from one to the other end of the soil processing trough, and a processed soil discharging stage including a soil discharging conveyer. The soil processing trough is provided with an inlet opening on the upper side of its fore end portion and an outlet opening on the bottom side of its rear end portion.
The present invention relates generally to a kind of soil processing machine, this soil processing machine is used to handle soil, reinforce the ground that loosens the soil by improving soil texture and quality, to adapt to the needs of special application target, be particularly related to a kind of self-propelled or vehicular soil processing machine, this soil processing machine can walking surfacewise on the surface of soil or region in the soil treatment process.
When excavating the soil, for example, in order to lay gas piping, water supply pipe or sewer pipe or, to wish very much to use its soil that clears out that carried out any processing not to be filled out the ground of digging back and forth for road construction operation or other foundation construction.But, in some cases, find the soil that digs out and be not suitable for backfill.In this case, just need abandon the soil that digs out, and fill out the ground of digging back and forth with quality or the better soil of characteristic.For example, in some cases, the mount that digs out contains the fragment of a large amount of stones, brick or concrete and/or metal or other impurity, and this soil forbids being used for backfill.In addition, use the weak soil backfill, for example very little and have as the soil of clay high viscosity or experienced excessive weathering and make the soil that solidifies difficulty carry out backfill with particle, can cause the subsidence of foundations on backfill ground.In addition, during the quality extreme difference of the soil that in the ground excavation operation, is dug out,, still have to it is abandoned as trade waste although this discarded object is had strict legal provisions.Therefore, press for the soil treatment device that the soil that can will be lower than standard quality changes useful resource into.
To this, when only including into the impurity of admixture in the soil, can after screening out, impurity be backfilling into the region of excavating.On the other hand, when soil is too soft, will cause ground to sink, therefore before backfill, have to it be handled with a kind of soil improvement or strengthening agent or improvement or reinforcement material if be used for backfill.For example, this agent, soil treatment method is that lime and cement are blended in the mud and soil that digs out traditionally, so that solidify, and forms the soil that has improved structure or quality, and this soil can be applicable to region that backfill was excavated or other purpose.
Be widely used in soil solidification and handle, with soil improver or to improve the typical hybrid machinery that material is blended in the soil that digs out be to be equipped with the mixing type machinery of rotation mixing arrangement and to have the mill type machinery that drum is pulverized in rotation.More precisely, with regard to mixing type machinery, the soil that digs out improves material with soil in a storage tank that has a mixing arrangement evenly mixes.This mixing arrangement both can be to have material in the blending tank is stirred batch-type with mixed function, also can be to improve at the soil with soil and interpolation to have the adding of continuing soil when material mixes to carry out the screw type of soil treatment operation function continuously.
No matter the type of mixing arrangement how, batch-type or continuous type all are located at soil processing machine in the fixing soil treatment factory usually, carry out work in fixing place.Except soil treatment equipment and relevant part such as conveyer, such soil treatment factory comprise also usually that the soil that is untreated that stores pending sand and soil stores and one store the soil of processing that improves the native produce that material processed crosses with soil and store the field.The sand or the soil that need to handle result from the foundation construction in road construction building site or construction site usually.The corresponding scale and the quantity that depends on the ground construction building site of variation of the quantity of sand of need handling or soil also depends on the number of times of this ground construction simultaneously.That is to say that owing to depend on these factors, the number change scope of soil of sending into and transport soil treatment factory is very big.Therefore, compare with the soil treatment ability of a factory, the quantity of handling soil is sometimes too little, is increased to such degree sometimes again, and is full to cause the soil that is untreated to store the field.
Can imagine, can suppress to send into and transport the fluctuation of quantity of the soil of soil treatment factory by gather sand and soil at large area region.But in this case, factory needs very big soil treatment ability, and this not only depends on the ability of soil processing machine, also depends on to be used to store the size that is untreated and has handled the place of soil.Need the extensive soil treatment factory nature in a large amount of vacant lots on position and environmental condition, to be subjected to various restrictions.
The excavation of sand and soil and handled native backfill and usually occur in road construction building site or other foundation construction building site.That is to say, although in fact the excavation of sand and soil and the backfill of having handled soil usually occur in population aggravation's city and on every side and quantity very big, the position of the extensive soil treatment factory in a large amount of vacant lots of needs is limited in underpopulated suburb.In addition, in order to make extensive soil treatment factory, must in very big zone, gather sand and soil for a long time to be fit to the productivity ratio work of its production capacity.This just means that sand and soil must ship from far place.But with tipping lorry sand transportation and earth removal outside the problem of high freight, also produced the problem of transporting the what is called " tipping lorry pollution " of truck traffic route along soil, and high freight has accounted for extremely big ratio in whole soil treatment cost.The expensive meeting of soil treatment causes illegally abandoning and environmental disruption.
The soil processing machine of other type, promptly the soil processing machine of mill type is disclosed, and for example, day patent specification H9-195265 of the present disclosure is disclosed.In this prior art, the structure of soil processing machine is vehicular or self-propelled, and a chassis that is contained on the carrier of crawler type basis is arranged.A soil pulverizer of pulverizing drum with a series of rotations is housed on this chassis.Like this, soil of excavating and the soil of interpolation improvement material inject soil and additive hopper, send into by the charging conveyer and pulverize drum, and this charging conveyer transmits the soil and the interpolation material of packing into to pulverizing drum.The soil of handling is discharged pulverizer by the discharge conveyer.That is to say that in this case, carry out the required whole machines of soil treatment and all be installed on the car body, like this, machine just can be transported to the ground construction building site and carry out work, for example in the road construction building site or other foundation construction building site.When excavation, processing and reclaimed soil, the vehicular of machine basis carrier can be walked on the ground that will handle and on every side.Therefore, by using vehicular or self walking soil processing machine, the expense of soil treatment can reduce significantly, can avoid like this transporting soil back and forth between soil treatment factory and foundation construction building site, and can get rid of the problem of environmental pollution that is caused by tipping lorry.
When stating the mill type mixing machinery before use, soil improves material with soil and is poured into rotation by the charging conveyer and pulverizes drum, and when soil is ground into fritter under the effect of impact of drum is pulverized in rotation, improves material with soil and mix.Therefore, in this case, soil does not need to improve material with soil and evenly mixes.Certainly, also can improve the degree of mixing by using numerous rotating percussion drums.Yet, because the number of times of the pulverizing of the improvement material of soil that gravity falls and interpolation collision increases, and pulverizer needs very big height, enough distances of falling are arranged with the improvement material of assurance soil and interpolation in order to make.This just means that the top of the hopper on the pulverizer is positioned at high height, and the improvement material of soil of handling and interpolation must be sent to that height by the charging conveyer.
As mentioned above, mill type soil treatment function is transported to foundation construction building site and Work in Place.In order to transport, by highway machine is transported to the construction site with trailer, and highway to limit the height of transport vehicle amount usually.Therefore, in order to transport on highway, soil processing machine is done as a wholely in height to be restricted.That is to say that the quantity of pulverizing in machine drum has a limit, and a limit is also arranged mixing the collision useful when stirring and the quantity of pulverization.For the rule that observe traffic laws on height of car, the quantity of pulverizing in soil processing machine drum has to be restricted to about three, and this is not enough for equably the improvement material of the soil excavated and interpolation being pulverized and is mixed into gratifying degree.
Come the ground of backfill may form the non-homogeneous sagging of ground with the soil of non-homogeneous mixing and the soil improvement mixtures of material of interpolation.In this case, for firm ground, eliminate non-homogeneous sinking, must soil be improved material with very uneconomic high blending ratio is blended in the backfill soil, to make ground excessively hard like this, and make in the subsequent step once more the excavated earth difficulty that becomes, for example, carry out pipeline construction or for other purpose.That is to say that because processing or finished soil quality are quite low, the soil processing machine of mill type has only limited application.
Have, the open text W098/53148 of international monopoly has described the unit mahine of a kind of hydraulic excavator digger and soil processing machine again.Or rather, at this, soil processing machine comprises the upper rotating body, a soil excavating gear and the soil treatment groove that is installed on the upper rotating body that are rotatably installed on the carrier of crawler type basis, a mixing arrangement is equipped with in this soil treatment groove inside, and between two crawler belts of basic carrier.The soil hopper at the top of the soil that digs out by being positioned at soil treatment groove one end is sent into the soil treatment groove, and simultaneously, soil improves material and sends into the soil treatment groove from upper rotating body.Soil improves material by the mixing arrangement in the soil treatment groove with the soil of interpolation to be mixed, and discharges by the soil discharge section that is positioned at the soil treatment groove other end.
Compare with the mill type soil processing machine, the machine of this prior art can be produced quite high-quality soil, but it also has a problem, and in order to keep the effect of excavator, the soil treatment groove has to be arranged in the extremely limited space of basic carrier side exactly.Therefore, this machine is applicable to the soil of handling relatively small amount in the foundation construction building site, and is not suitable for the application that need handle a large amount of soil at short notice efficiently, in foregoing large-scale soil treatment factory.
By aforementioned part as seen, the inventor has carried out extensive studies, attempt to develop a kind of soil processing machine, thereby this soil treatment function is improved material with the soil of soil and interpolation and is mixed high efficiency, low cost equably, produces high-quality soil product on a large scale, eliminate traffic problems simultaneously, as the problem of environmental pollution of tipping lorry, therefore, on the basis of achievement in research below, successfully finished the present invention.
At first, have the soil treatment factory of fixing soil treatment system or equipment can the high-quality soil of large-scale production, but compare with its production capacity, except the operating efficiency that is difficult to keep suitable, it have also comprised very high freight.In order to solve the problem of high freight, wish that soil treatment factory is positioned as close to the city, the soil product overwhelming majority of having handled consumes the many foundation constructions building site in the city.And guarantee that the difficulty that has suitable place that huge soil treatment equipment is installed can be overcome to a certain extent by using limited vacant lot effectively.
Consider and excavate soil or consume the relation in geographical position that the soil of handling carries out the ground construction building site of backfill or other purpose, as long as the service range of soil treatment factory is limited in one or several specific zone, its soil treatment equipment does not just need very big space.In addition, when gathering and handle the soil of excavating, can at first store the pending soil that ships, and then store the soil product of having handled to be transported with a same storage field.By effectively utilizing the space of soil treatment equipment in this way, it self space factor can have the improvement of certain degree.Therefore,, provide quite small-scale soil treatment factory from reducing cost of transportation and preventing the position of the environmental pollution of tipping lorry, increase in the regions of particular service or with it the soil treatment factory quantity of adjacent area be very beneficial.
But if all be equipped with fixing soil processing machine in each factory, so such midget plant can cause mechanical efficiency low when turning round.This is owing to generally, and the quantity that the soil of excavating that comes is transported in the each reception of the midget plant of little service range is quite few, needs some times just can make the soil of each factory store the field and piles.Therefore consider from mechanical efficiency that the soil of beneficially soil processing machine being delivered to some soil treatment factories stores the field rather than all equips fixing soil processing machine in each midget plant.
Therefore, set up the mechanical efficiency that a soil treatment network system can significantly improve soil processing machine, the small-sized soil that is equipped with relative simple device and is positioned at the different location of some adjacent coverages that this soil treatment network system covers some stores, in order effectively to utilize the vacant lot of distributing, each stores the field and is arranged to store vacant lot with a soil and had not only stored be untreated soil but also the storage soil of sending into of processing to be transported, in case a soil stores the field and fills the soil that is untreated, and just a self walking soil processing machine can be sent to this soil treatment field at once.Set up such soil treatment system that constitutes by some small-sized soil treatment fields and can produce the high-quality soil of having handled generally on a large scale effectively, and can significantly reduce cost, shorten the distance of tipping lorry transportation soil, thereby reduce the problem of existing traffic system.
The soil processing machine that is used for this purpose has a movable soil treatment system of providing for oneself, and preferably structure is very compact.In addition, machine should be able to stably be produced high-quality soil, and has the ability that can handle a large amount of soil at short notice effectively.

The specific embodiment
Preferred embodiment shown in inciting somebody to action is with reference to the accompanying drawings below described the present invention in detail.What Fig. 1 was extremely shown in Figure 3 is vehicular of the present invention or self walking soil processing machine.Among Fig. 1, the basic carrier of 1 expression machine, it is the caterpillar that has crawler belt 1a, this crawler belt is known in the art.Because basic carrier 1 is a crawler type, therefore when the soil that will dig out is thrown in the machine, can prevent from for example to make the whole instability that occurs of machine owing to loading to impact.But, load continuously under the situation of the soil that digs out with conveyer or similar machinery being arranged to, basic carrier also can be a wheeled vehicle.
A soil feed zone 3 and a soil treatment section 4 are installed on the main frame 2 of basic carrier 1, and soil feed zone 3 is positioned at its front portion, and in the left-hand component of Fig. 1, soil treatment section 4 is positioned at after the feeding part 3.In addition, there is a soil to discharge the back that section 5 is positioned at soil treatment section 4.This soil is discharged section 5 lower positions from processing section 4 and is extended upward sideling.A machine chamber 6 is arranged above soil treatment section 4, and this machine chamber is equipped with mechanical part, as engine, and hydraulic pump, switching valve element etc.Machine chamber 6 is installed on the cramp bar 6a that stands on the main frame 2.
The soil that digs out except transmission and the soil of interpolation improve the connecting gear of material, and soil feed zone 3 also comprises a measuring mechanism that is used to measure the soil quantity delivered.Soil feed zone 3 also has a charging conveyer 10 in addition, and it improves material to processing section 4 transmission with the soil of soil and interpolation.Upstream position at the direction of transfer of charging conveyer 10 has a soil hopper 20 to be positioned at the top of charging conveyer, and an additive hopper 30 is arranged on the back location of soil hopper 20.The soil quantity delivered is measured by charging conveyer 10, then regulates according to the soil quantity delivered of measuring by the additive quantity delivered of additive hopper 30.
Charging conveyer 10 is by extending framework 7 supportings, and this extension framework 7 stretches out to truck main frame 2 the place aheads.This extension framework 7 is inclined upwardly from its front end to rear end, and its front position is minimum, and its rear end then links to each other with truck main frame 2.Therefore, be inclined upwardly from its front end to rear end by the charging conveyer 10 that extends framework 7 supportings.For the ease of adding soil by hopper 20, the front end of charging conveyer 10 is positioned on the minimum working level, and it is higher than the surface of rolling of crawler belt 1a, but is lower than truck main frame 2.
As shown in Figure 4, charging conveyer 10 has the conveyer belt 11 (being illustrated by the broken lines) of an annular, and this conveyer belt is made by rubber slab or similar material, and according to the weight that applies load, deflection to a certain degree can appear in this material self.In addition, 12 expression conveyor frame, rotatably lateral support rotating shaft 13a and 14a in two end, is respectively applied for driven roller 13 and is driven or driven voller 14.Endless belt conveyer 11 is walked around driven roller 13 and driven voller 14.The rotating shaft 13a of driven roller 13 and hydraulic motor 15 couplings.Therefore, when rotating shaft 13a was driven by hydraulic motor 15 rotations, conveyer belt 11 was driven the direction rotation of pressing shown in Fig. 4 arrow by driven roller 13.
Transmit on the dual-side on surface in the load along conveyer belt 11, guide plate 16 is arranged, the upper end of this guide plate 16 extend on the load transmission surface of conveyer belt 11 with predetermined length respectively.These guide plates 16 play barrier wall, overflow to the side that transmits passage to prevent the mound on the conveyer belt 11.In addition, below conveyer belt 11, be provided with some guide reels 17 within it with predetermined space along transmitting passage.The rotating shaft 14a of driven voller 14 directly is connected on the conveyor frame 12, but is connected indirectly on the conveyor frame 12 by a tension-adjusting gear 18, and the effect of this tension-adjusting gear is to keep constant-tension on conveyer belt 11.This tension-adjusting gear 18 comprises a tension feeler device, in view of the above can be with the tension adjustment of conveyer belt 11 to a predetermined value, however do not show especially in the drawings.
Soil hopper 20 all has the box-like frame works of opening to constitute by upper and lower surface.Shown in Fig. 5 was concrete, this soil hopper 20 comprised from the upper frame part 20a of top reception soil and the underframe part 20b of soil is provided to charging conveyer 10.The upper frame part 20a of soil hopper 20 is to its upper open end deflection, and like this, soil can be thrown in the hopper 20 smoothly.On the other hand, underframe part 20b assembles towards its bottom open end, by bottom open end soil is supplied with charging conveyer 10.Or rather, underframe part 20b is the same or smaller with the width of the conveyer belt 11 of charging conveyer 10 towards the width of bottom convergence.Soil hopper 20 is securely fixed on the truck main frame 2 by frame unit 8.
Be provided with a screening plant 21 in the upper frame part 20a of soil hopper 20, for example sieve plate or lattice plate screen out impurity thus.This screening plant 21 can be fixed on the opening part of soil hopper 20 upper frame part 20a, or can be changed into can be by using vibration generating apparatus in upper frame part 20a internal vibration.The upper open end of upper frame part 20a that screening plant 21 is housed is to lopsidedness.Like this, when the soil that digs out was thrown into soil hopper 20 by the bucket of hydraulic crawler excavator from the front, soil can not then get off along screening plant 21 landings of tilting by the bulk solid impurity of screening plant 21 selectively by screening plant 21.
The soil of throwing into soil hopper 20 can drop on the conveyer belt 11 of charging conveyer 10 through underframe part 20b under the gravity effect, and is supplied with forward by conveyer belt 11.Though not necessarily mandatory necessary condition, but wish to regulate and can suppress as much as possible the quantity delivered of the soil on the conveyer belt 11 as much as possible very much the fluctuation of soil quantity delivered, mix so that can improve material with fixing mixing ratio to the soil that adds, as hereinafter will narrating according to the quantity delivered of soil.
Because the edaphic end face on the conveyer belt 11 should be limited on the level of upper end of guide plate 16 projectioies, so be provided with a door 22 in the exit, bottom of soil hopper 20.The height of this open area of 22 the limitation in height of the soil that leaves hopper 20 on the level of the upper lobes end that does not exceed guide plate 16.Therefore, when conveyer belt 11 motions, soil is sent on the conveyer belt 11, and its thickness is adjusted by the height of door 22.In addition, a smooth roller 24 that has claw bar 23 is installed rotatably in the outside of door 22, is carried out smooth to end face whereby through 22 soil of supplying with forward of moving into one's husband's household upon marriage.Thus, soil forwards on conveyer belt 11 with a constant predetermined altitude or thickness.
The hopper 30 that the soil that is used to add improves material is fixed on truck main frame 2 firmly by pillar 9, and its arrangement such as Fig. 6 are to shown in Figure 9.At this moment, in order to improve soil, can different interpolation materials be sneaked in the soil according to application target.For example, when the soil of producing is used for the ground that backfill dug or is used for improving ground, except other required additive, lime and cement can also be blended in the soil.Can add different soil according to different application targets and improve material, for example, in order to improve clay, in order to give damping characteristics to ground or in order to improve the soil in farmland.
Additive hopper 30 mainly is made of an additive storage bin part 31 and a quantitative feeder 32.Storage bin 31 comprises a rectangular box shape top 31b and a cylindricality bottom 31a.Rectangular box shape top 31b is provided with top cover 33, and this top cover 33 is made up of a pair of hinged cover plate 33a.Cover plate 33a can be with outside direction ground separated from one another swing open, and remains on the position of upwards opening with suitable block.The soil that adds improves material from flexible package bag 34 feeding hoppers 30, and the packed full soil that adds of this flexible package improves material and is through the cover plate 33a that upwards opens and from the rectangular box shape top 31b that is placed on storage bin 31 therebetween.Be provided with a blade that raises up 35 in the bottom of box-like top 31b.Like this, when flexible package bag 34 was put into additive hopper, the bottom of flexible package bag 34 was cut by blade 35, and the soil of the interpolation in the flexible package bag 34 improves material and can flow into downwards among the cylindricality bottom 31a of storage bin 31.In case the soil that adds improves material and enters by this way in the hopper 30, top cover 33 is just closed at once, scatters on the machine or around the machine to prevent additive material.
See that by Fig. 7 is clear by a perforate 36, cylindricality bottom 31a is communicated with quantitative feeding part 32.Therefore, the soil of the interpolation in the 31a of the cylindricality bottom of storage bin 31 improvement material can flow in the quantitative feeding part 32 by this perforate 36.At this moment, compare with the gross area of cylindricality bottom 31a, the aperture area of this perforate 36 is quite little.Therefore, only depend on gravity flow to supply with quantitative feeding part 32 if the soil that adds improves material, then arch formation will hinder the steady supply to quantitative feeding part 32.For fear of arch formation, a cross bar revolving door 37 is arranged in the bottom of the cylindricality bottom of storage bin 31 31a or near the bottom.This cross bar revolving door 37 and 38 couplings of hydraulic motor also drive rotation by it, this hydraulic motor 38 be arranged on cylindricality bottom 31a below.When revolving door 37 rotated, the soil in the bottom of cylindrical section 31a was stirred, and forced it steadily to flow in the quantitative feeding part 32 and do not have the viscous flow phenomenon.
Quantitatively feeding part 32 comprises a box body 40, and the width of this box body 40 width with the conveyer belt 11 of charging conveyer 10 basically is identical.Be provided with an additive charging aperture 41 in the lower end of box body 40, this charging aperture 41 is a long hole shape, and the width of its length and conveyer belt 11 roughly quite or smaller.The additive material of sending into quantitative feeding part 32 from storage bin 31 joins on the soil that is transmitted by conveyer belt 11 by additive charging aperture 41.When the soil that adds was improved material supply conveyer belt 11, the soil improvement material that does not need to add was assigned on the whole width of conveyer belt 11.If desired, feeding part 32 can be arranged to additive material is provided to the middle body of conveyer belt 11.
The quantity delivered that the soil of the interpolation of coming out from quantitative feeding part 32 improves material is adjustable.Special the end portion of box body 40 is surrounded by the arcwall 40a at its front and rear as Fig. 8 and shown in Figure 9, and this end portion leads to above-mentioned additive charging aperture 41, has a quantitative feeder 42 to be rotatably installed between the two arcwall 40a.This quantitative feeder 42 by a level pass the rotating shaft 43 of box body 40 end portions and some radially dividing plate 44 form, these dividing plates 44 with predetermined angle intervals (being depicted as the intervals of 90 degree in a particular embodiment) be installed in rotationally rotating shaft 43 around, so just determined a V-arrangement measuring fixed amount container 45 on 44 on adjacent dividing plate.At this moment, the spacing between the outer end of the width of additive charging aperture 41 and two adjacent dividing plates 44 is basic identical or slightly narrow.Arcwall 40a forms one at least 90 degree or bigger arcs.
When rotating shaft 43 rotations, four dividing plates 44 that constitute measuring fixed amount container 45 rotate around rotating shaft 43, and outer end separately and arcwall 40a keep sliding-contact.Therefore, arcwall 40a role is to remove unnecessary soil from each measuring fixed amount container 45.Rotating shaft 43 revolutions are crossed 1/4 swing circle, for example, just supply with the soil of scheduled volume when locational quantitative feeder 42 shown in Figure 8 is forwarding position shown in Figure 9 on the conveyer belt 11 of charging conveyer 10, it is corresponding with the internal capacity of each measuring fixed amount container 45.Therefore, the soil of the interpolation of coming out from quantitative feeding part 32 quantity delivered of improving material can be regulated by the running speed that changes rotating shaft 43.In order to regulate the running speed of rotating shaft 43 well, the output shaft that is contained in the motor 46 on the box body 40 passes through an actuating unit 47 in the outside of box body 40, as driving-belt or analog, with rotating shaft 43 couplings.
The quantity delivered that the soil that adds improves material is along with being changed by the variation of the quantity delivered of the soil that conveyer belt 11 transported of charging conveyer 10.The adjusting that the amount of the soil that is transported by conveyer belt 11 can be undertaken to a certain degree by door 22 and smooth roller 24, the effect of door 22 and smooth roller 24 is height or a thickness of adjusting the soil layer on the conveyer belt 11, but they can accurately not keep constant soil conveying capacity.Therefore, in order to survey the amount of the soil that transports by conveyer belt 11, a soil charging measurement mechanism 50 is set on charging conveyer 10.Exactly, this soil charging measurement mechanism 50 is used to survey the weight of the soil that is transported by conveyer belt 11, and structure disposes as shown in Figure 10 and Figure 11.
In these accompanying drawings, 51 expression pair of rolls, they be fixedly supported upon on the spaced position of conveyor frame 12 and by contact with reclining of the back side of moving conveyer belt 11 around himself rolling.Soil charging measured zone is meant the zone between these fixing rollers 51.This soil charging measured zone comprises a weight measurement roller 52 that approximately is positioned at two stationary rolls, 51 centres and reclines and contact with the back side high-quality of conveyer belt 11.In this case, the degree of flexibility of 52 pairs of conveyer belts 11 of this weight measurement roller is surveyed, and this conveyer belt 11 is made by flexible material and according to the downward deflection of weight self of the soil that loads, just as mentioned before.
For this reason, weight measurement roller 52 is contained in an end of a wobble-plate 54, and this wobble-plate 54 is bearing on the main frame 12 swingably by a bearing part 53.At the other end of wobble-plate 54 load cell 55 of ining succession, this load cell 55 have a load unit or similarly device as Weight-measuring device.Therefore, when operating conveyer belt 11 had loaded a mound, as long as when mound arrives soil charging measured zone between these stationary rolls 51, because flexible under the effect of mound weight, conveyer belt 11 occurred sagging.As a result, weight measurement roller 52 is pushed downwards along direction shown in the arrow D of Figure 11, and the other end of the wobble-plate 54 that links to each other with weight measurement roller 52 then moves along the direction shown in the arrow U, load cell 55 is applied the load of an increase.Like this, just the amount of the soil that can transport conveyer belt 11 according to the detectable signal of load cell 55 is measured.
With regard to charging conveyer 10, if soil hopper 20 and additive hopper 30 position each other can be near as far as possible, the transmitting range that the soil that digs out in order to supply and the soil of interpolation improve the conveyer belt 11 of material just can shorten.But, as previously mentioned,, therefore just need to increase the length of conveyer belt 11 because soil charging measurement mechanism 50 is located between hopper 20 and 30.With regard to this on the one hand, conveyer belt 11 does not need to increase length significantly, because soil hopper 20 and additive hopper 30 boths have predetermined volume, therefore can give soil charging measurement mechanism 50 slot millings under the conveyer belt 11.However, because the soil layer on the conveyer belt 11 is adjusted to predetermined height or thickness by door 22 and smooth roller 24, therefore, when available installing space is very little, still can omit soil charging measurement mechanism 50.
In aforementioned manner, the soil of soil and interpolation improves material and is transported to the other end of charging conveyer 10 forward by conveyer belt 11, and this end links to each other with a soil treatment groove 60 of processing section 4.This soil treatment groove 60 is made of a main body 60a and a top lid member 60b basically, and main body 60a is provided with an opening on the preset range at its top, and top lid member 60b is detachably fixed on the main body, with the closure tip opening.Main body 60a is fixedly mounted on the top of truck main frame 2.The machine chamber 6 that is positioned at top lid member 60b top does not contact with top lid member.Therefore, can upward top lid member 60b be removed or separate from the main body 60a that is contained on main frame 2 operating positions.
The soil that is transported by conveyer belt 11 and the soil of interpolation improve material and supply to soil treatment groove 60 from top, so that mix or stir process in the soil treatment groove.For this reason, charging conveyer 10 will place the eminence that is higher than treatment trough 60 usually.If charging conveyer 10 horizontal supportings are on main frame 2, then soil hopper 20 just has to be positioned on the higher position, and this soil that is not easy to dig out throws.For this reason, according to the present invention, charging conveyer 10 is bearing on the extension framework 7 of inclination, and this extension framework 7 is tilted to down from truck main frame 2 and stretches out.Arrange that like this upstream extremity of charging conveyer 10 and soil hopper 20 are positioned at low position, the soil that digs out can throw extremely easily.
Referring to figs 12 to Figure 15, shown is the internal structure of the soil treatment groove 60 of processing section 4.In Figure 12, can know and see, soil treatment groove 60 be shaped as the rectangular box shape container, essentially horizontally be installed on the truck main frame 2, and along the longitudinal extension of truck main frame.This soil treatment groove 60 is provided with swing door 61 on its lateral wall.In addition, this soil treatment groove 60 has an import framework 62 and an outlet framework 63, and this import framework surrounds the charging aperture on soil treatment front of the slot part, and the outlet framework then surrounds the discharging opening below soil treatment groove rear end part.To shown in Figure 15, a pair of oar blade type blender 64 relative parallel longitudinal ground are through soil treatment groove 60 as Figure 13.Each oar blade type blender 64 is made up of a rotating shaft 65 and many blades 66, and these blades 66 become the mode compartment of terrain of predetermined angle to be installed on the rotating shaft 65 as stirring or hybrid element with the longitudinal axis with rotating shaft 65.In illustrated specific embodiments, each blade element 66 comprises a cramp bar 66a and a blade sheet 66b, and this cramp bar is fixed on the rotating shaft 65 firmly, and blade sheet 66b then is fixed on the cramp bar 66a with bolt 66c.Therefore, when each blade 66 wearing and tearing or damage, just can change easily.
Rotating shaft 65 1 rotations, each blade 66 just rotates around rotating shaft 65 in soil treatment groove 60, like this, the soil that enters the soil of treatment trough 60 and interpolation improves that material just is rolled and evenly mixes each other, transmits to the discharging opening at the rear end part of treatment trough 60 simultaneously.In illustrated specific embodiments, soil treatment groove 60 is provided with a pair of oar blade type blender 64 within it.However, it should be understood that soil treatment groove 60 can be provided with more or less oar blade type blender, this depends on the width and the height of soil treatment groove.For example, when the height of soil treatment groove 60 increases, but it can be with the oar blade type blender of the bigger large-size of less radius of turn.On the other hand, but when the highly less width of being shaped as of soil treatment groove 60 was big, it preferably used the more oar blade type blender that laterally is being arranged side by side.Therefore, can obtain the quantity of the oar blade type blender 64 of high mixing efficiency will be determined by the size of soil treatment groove 60, and the size of soil treatment groove 60 is determined by the width of truck main frame 2 and the total height of machine again.But,, the oar blade type blender 64 that rotates in the opposite direction each other of equal number should be set in order in soil treatment groove 60, steadily to mix and transmit the soil improvement material of soil and interpolation efficiently.
Two ends of the rotating shaft 65 of each oar blade type blender 64 can be rotated to support in the bearing 67, and as shown in figure 13, the front end of rotating shaft 65 extends in the housing of groove drive part 68, and this groove drive part is close to the front end of soil treatment groove 60.What be contained in each rotating shaft 65 fore-end is the travelling gear 69 that meshes each other.There is a travelling gear 69 to be meshed with driven wheel 71 on the output shaft that is installed in hydraulic motor 70.Therefore, under the rotation of hydraulic motor 70 drove, each rotating shaft 65 that has blade 66 was simultaneously with opposite direction rotation.In addition, a guide plate 72 is installed, is improved material in order to the soil that prevents soil and interpolation and partly remain in a standstill at the inferior horn of treatment trough 60 in the bottom of soil treatment groove 60.The rear end part of this guide plate 72 has perforate, in order to the outlet framework 63 of treatment trough 60 to be installed.
Blade 66 is along the whole distribution of lengths of the rotating shaft 65 of each oar blade type blender 64, and said whole length is in the import framework 62 and the Mixed Zone between the outlet framework 63 of soil treatment groove 60.Therefore, 65 two bearing at end 67 of supporting rotating shaft are installed in respectively on the position of the front of import framework 62 and the back that exports framework 63.Therefore, can steadily mix each other in reliable mode, transmit with the outlet framework 63 of constant speed simultaneously to soil treatment groove rear end by the soil of import framework 62 supplies and the soil improvement material of interpolation.
By in soil treatment groove 60, the soil that adds being improved the immixture that material is blended into the oar blade type blender 64 in the soil that digs out equably, formed the improvement soil of forming by the homogeneous mixture of soil that digs out and soil improvement material, and it has been discharged from the outlet framework 63 of treatment trough 60.Improved soil since the gravity effect drop on the discharge conveyer 73 that is positioned at below the outlet framework 63.In this case, the soil receiving terminal of discharge conveyer 73 be positioned at be lower than the outlet framework 63 the position on, this outlet framework 63 below soil treatment groove 60 on.Discharge conveyer 73 tilts to install, and tilts to rise towards another transmission end.If this is because conveyer is installed with horizontal level, the soil that is difficult to handle piles big mound.
When improving material with lime as soil, improving the soil product that the homogeneous mixture of material forms by the soil of soil and interpolation then is granular form.For with steadily transmitting improved soil product on the direction of discharge conveyer 73 on being tilted to, be limited in certain scope to the inclination angle of conveyer.This means that for improved soil product is piled up, the length of soil discharge conveyer 73 must extend to a certain degree.Consider from this respect, may be by the length overall that folding form reduces soil processing machine be made in the rearward end or the outer end of discharge conveyer 73.So, discharge conveyer 73 will particularly have a folding point in the position of the upper end that is lower than additive hopper 30 in the position that is lower than the whole peak of soil processing machine.Therefore, soil discharge conveyer 73 is made up of a fixing conveyer part 73a and a folding conveyer part 73b, fixing conveyer part 73a is fixedly supported upon on the truck main frame and on the direction on being tilted to and stretches out below soil treatment groove 60, folding conveyer part 73b is articulated in the upper end of fixing conveyer part 73a by bindiny mechanism 74, and can be folding along the direction of arrow of Fig. 1.Like this, folding conveyer part 73b is driven by hydraulic cylinder or other suitable drive mechanism, and moves back and forth in the folding position shown in operating position shown in the solid line and the dotted line.
Figure 16 has illustrated to describe the situation that soil that a kind of vehicular soil processing machine that uses aforementioned structure carries out in small-sized soil treatment field improves operation.In handling the field, the soil that is untreated that has a pile or number heap to gather in advance.At first, the soil that is untreated is thrown in the soil hopper 20 of machine with the work of beginning soil treatment.For this reason, can use a hydraulic crawler excavator PS as the instrument of untreated soil being thrown into the soil hopper.Thereby,, just can be processed into the product that improves quality with handling an interior mound of gathering by using vehicular soil processing machine and hydraulic crawler excavator PS.
For handle be deposited in handle in soil on some zone, rise with the bucket handle of the hydraulic crawler excavator mamoty that is untreated, throw into the soil hopper 20 of soil processing machine successively from an end.When the soil that comes out from hopper 20 was transmitted by charging conveyer 10, a kind of soil of interpolation improved material and adds and be poured on the soil surface on the conveyer 10 from additive hopper 30.Inner end at charging conveyer 10, the import framework 62 that the soil of soil and interpolation improves the treated groove of material drops in the soil treatment groove 20, and be mixed with each other equably under the immixture of oar blade type blender 64, the outlet framework 63 towards treatment trough 20 transmits simultaneously.Thereby, produced the soil product in the outlet of soil treatment groove 60, for example, soil product in pelletized form, the quality improvement of this soil product and also improve by the soil of soil that digs out and interpolation that a kind of homogeneous mixture of material forms.The improved soil product that comes out from outlet framework 63 is deposited in the predetermined area of handling the field by discharge conveyer 73.
Along with the carrying out of soil treatment work, handle an interior mound that is untreated and progressively consume, expose vacant lot, this vacant lot can be used to pile up improved soil product.Thereby the most of vacant lots in the soil treatment field can store the soil of gathering from the ground construction building site that is untreated as both being used to, and are used to store the storage location of the improvement soil that is produced continuously by soil treatment work again.The vehicular soil processing machine that has a basic carrier 1 by use just can be realized the efficient utilization to the confined space like this.By handling basic carrier 1, along with the minimizing of the storage area of the soil that is untreated, soil processing machine can be synchronously a motion in handling.
When piling up the soil of handling in handling the field, the whole improvement soil products that come out by discharge conveyer 73 can store in the predetermined area of handling the field.But, in some cases, wish improved soil product to be classified according to granular size.For this reason, increase a sorting machine 75, as shown in figure 16.At this moment, this sorting machine 75 is lightweights, mainly is made up of a sieve 76 and a conveyer 77.Sieve 76 has predetermined screen size, and preferably can vibrate, so that allow the particle less than preliminary dimension pass through, for example, less than 13mm, 20mm or 25mm.Its particle size can transmit by conveyer 77 by the improvement soil of sieve 76 again, and piles up in predetermined storage location.The improvement soil of larger particle size that can not be by sieve 76 is also handled by setting and hardening and has been improved quality, therefore can carry out foundation backfill with it, perhaps further by re-using after the granular size sorting.
In order to improve the quality of soil product, wish from the soil that is untreated, to remove the fragment of stone, brick or concrete and metal or other impurity in the preproduction phase.As previously mentioned, the screening plant 21 of soil hopper 20 is exactly to be used for this purpose.By the sieving actoion of screening plant 21, have only soil to enter into soil hopper 20 basically, can not then slip down by the impurity of screening plant 21 along the sloped top face of screening plant, therefore the phenomenon that impurity stops up soil charging work can not appear.
Have, the soil of regulating soil and interpolation exactly improves the mixing ratio of material again, with the degree of consolidation that keeps soil within predetermined scope.In this respect, the consolidation effect of the soil of interpolation improvement material changes with the characteristic of pending soil.Therefore wish to determine optimal mixing ratio by test in advance.The mixing ratio of soil and additive material both can be a volume ratio, also can be weight ratio.But, consider for example soil density and these influence factors of viscosity, preferably determine a kind of weight ratio.
Soil charging measurement mechanism 50 is used to measure the weight from the soil of soil hopper 20 supplies.This soil charging measurement mechanism 50 is arranged through the load that is applied on the weight measurement roller 52, directly the weight of the soil of transmission on the charging conveyer 10 is surveyed.Improve material as for the soil that adds, it is to supply with charging conveyer 10 at the downstream position of soil charging measurement mechanism 50 from additive hopper 30.The quantity delivered of additive material can be by changing quantitative feeding part 32 the rotary speed of quantitative feeder 42 regulate.Therefore, according to the signal that load cell 55 sends motor 46 is controlled, regulate the rotary speed of quantitative feeder 42, and the soil that changes interpolation improves the quantity delivered of material, by this way, even fluctuation appears in the soil quantity delivered of charging conveyer 10, also can keep the mixing ratio of being scheduled to.
The quality of the soil product of having handled depends primarily on the degree that soil and additive material are mixed with each other in soil treatment groove 60.In this respect, the inside soil treatment groove 60 that is provided with oar blade type blender 64 can improve material with the soil of soil and interpolation and evenly be mixed into gratifying degree.Shown in specific embodiments in, treatment trough 60 is provided with a pair of oar blade type blender 64, this is arranged as in the opposite direction rotation to oar blade type blender 64, shown in Figure 15 direction of arrow.Therefore, in soil treatment groove 60, the soil that adds and the soil of interpolation improve material and roll up and down continuously, and each place in the whole length range of treatment trough all is cut into fragment under the shearing of revolving vane 66 and immixture basically, these blades 66 are installed on the rotating shaft 65 of oar blade type blender 64, and the result has formed a kind of uniform mixture.Simultaneously, because each blade 66 is with respect to the axis inclination installation of rotating shaft 65, so under the immixture of blade 66, the soil of soil and interpolation improves mixtures of material and transmits with the outlet framework 63 of horizontal direction towards treatment trough 60 basically.In addition since between the import framework 62 of soil treatment groove 60 and outlet framework 63 barrier not resemble the bearing, so the mixture of soil and additive material steadily transmits with constant speed.Thus, the soil of non-constant also can be processed into the soil product that quality is suitable for application target.In addition, except import framework 62 and outlet framework 63, soil treatment groove 60 is arranged to handle soil basically in the space of sealing, is scattered towards periphery when the stirring of experience blade 66 and the immixture with prevention soil and additive material.
The soil of soil and interpolation improves material should keep a period of time in treatment trough 60, this time is necessary, because the blade 66 of oar blade type blender 64 will be sheared soil, and efficiently the soil of soil and interpolation is improved material and be mixed into gratifying degree.In this respect, because the soil of soil and interpolation improvement material along continuous straight runs basically transmits by treatment trough 60, the height that therefore need not additionally increase treatment trough 60 just can guarantee enough time of staying, for example, length that can be by increasing treatment trough 60 or set up suitable transfer rate by the inclination angle of regulating mixing paddle 66 and guarantee.
When soil was bonded at blade surface, the shearing of mixing paddle 66 and the efficient of immixture will reduce.In this respect, the blade 66 of an oar blade type blender 64 is extended between the blade 66 of another oar blade type blender 64, like this, when the axis direction of rotating shaft 65 was seen, the blade 66 of two oar blade type blenders 64 was alternately rotating on the position overlapped basically.Therefore, during work, the lip-deep soil that is bonded at the blade 66 of an oar blade type blender 64 is struck off by another blade 66 at the oar blade type blender 64 of opposite direction rotation.Therefore, because this automatic cleaning action, all blades 66 seldom cause mixing efficiency to descend owing to being stained with soil.
In addition, after carrying out processing of soil or work of treatment, can remove the end face that top cover 60b opens cell body 60a, perhaps can open the side door 61 on the sidewall of cell body 60a, like this,, just can extremely easily it be removed from blade 66 if be stained with soil.This arrangement can also make treatment trough 60 be easy to maintenance.That is,, just can make blade 66 held stationaries duty efficiently by carrying out this M R with suitable frequency.When blade 66 use surpass a period of time after owing to contact with soil friction when wearing and tearing, the blade part 66b of wearing and tearing can the replacing easily by removing bolt.
When the soil that is untreated of supplying with soil treatment groove 60 is low viscosity,, under appropriate stirring condition, should hold it in as far as possible for a long time in the treatment trough 60 for the soil that promotes soil and interpolation improves reaction between the material.Therefore when clayed soil was hanged down in processing, oar blade type blender 64 was preferably with low speed rotation.On the contrary, high viscosity soil can trend towards becoming entangled in around the blade 66, and hinders the rotation of oar blade type blender 64, and the worst situation is to make oar blade type blender 64 be in locking state.Therefore, when handling higher tack soil, oar blade type blender 64 should be with rotation at a high speed.
As previously mentioned, the soil of falling charging conveyer 10 through soil hopper 20 is homogeneous thickness or height by door 22 and smooth roller 24 are smooth basically.In addition, the weight of the soil of being supplied with on charging conveyer 10 is surveyed by soil charging measurement mechanism 50.Thereby can draw the volume weight of the soil that supplies from weight signal from soil charging measurement mechanism 50.As long as the characteristic of the soil that supplies is identical, higher volume weight has reacted higher viscosity.Therefore,, can control the hydraulic motor 70 that drives oar blade type blender 64 according to from weight signal from soil charging measurement mechanism 50, so that when confession soil high viscosity, rotate at a high speed, low speed rotation when confession soil hangs down viscosity.
Because soil processing machine is designed to a plurality of processing field for usefulness, after the work of treatment of relatively small amount soil is finished in a processing field, just it is transported to another soil treatment field from a soil treatment field.For this reason, as shown in figure 17, soil processing machine is placed on the trailer TR that is drawn by trailer TT and transports.The goods that transports with this trailer TT is subjected to the restriction of restriction, particularly length, width and the height of size.The most important thing is that the machine that is transported by trailer is in height enough little, otherwise transportation route will be subjected to the restriction of the road of tunnel gap, bridge frame height or similar obstacles.Certain part of machine can disassemble before with trailer TT transportation.But, in this case, machine is being transported in the transportation of another soil treatment field by a soil treatment field, and have to dismounting and refitting are although these work extremely bother and elapsed time.
In most cases, the height of soil processing machine depends on the height and position of soil import framework 62, and the soil of soil and interpolation improves material and enters treatment trough 60 by this import framework 62, and this treatment trough 60 constitutes the main part of soil treatment mechanism.As previously mentioned, when stirring each other and mixing, the soil of adding and the soil of interpolation improve material and transmit by treatment trough 60 in the horizontal direction basically.Therefore, in order to carry out soil treatment work efficiently, the volume of treatment trough can strengthen and not increase its height.Certainly, the soil that transports soil and the interpolation charging conveyer 10 that improves material should allow the transmission surface of its conveyer belt 11 be positioned on the position that is higher than soil treatment groove 60.In addition, because soil and additive material unload or supply with by hopper 20 and 30 respectively, this hopper 20 and 30 mostly reaches on the transmission surface of conveyer belt 11.But, because restriction and reduced the height of soil treatment groove 60, in this case, hopper 20 and 30 position also have the reduction of same degree.In addition, because charging conveyer 10 is tilted-putted, soil hopper 20 just can be placed on the more position of low clearance.In order to reduce the filling frequency that the soil that is consumed improves material hopper 30 in the soil treatment course of work, this hopper should have big as far as possible storage volumes.For this reason, this hopper 30 needs enough big volume, and it also will be positioned at the highest position, as shown in Figure 1.But, because additive material charging aperture 41 opens on the sloping portion of the conveyer belt 11 of charging conveyer 10, so the position of additive hopper 30 also can correspondingly reduce.In addition, the upper end of the folding discharge conveyer 73 in upper part can fold on the position of the upper end that is lower than additive hopper 30.
In addition, machine chamber 6 is positioned at idle place, and this free time is on the soil treatment groove 60, after the additive hopper 30 and before discharge conveyer 73.In addition, the position of soil hopper 20 and additive hopper 30 abuts one another, and machine chamber 6 also nestles up additive hopper 30.Therefore, discharge conveyer 73 can fold towards the vacancy, to reduce the height of soil processing machine integral body.
Therefore, can subtract into the size of soil processing machine the shape of a compactness, particularly can reduce height, it just can steadily be handled the field from one easily by trailer TT and be transported to another processing field like this, and need not be disassembled into many parts.When transporting, the vehicular soil processing machine can be enough self the steady trailer TR up and down apace of self-propelled mobile devices.In addition, except compact conformation, this machine can be in treatment trough 60 soil of mixed soil and interpolation efficiently improve material, thereby extensive and high production rate produce a kind of high-quality soil product.
With reference to Figure 18, the controller 80 shown in the figure is used to control the operation of whole soil processing machine.The signal that this controller 80 sends according to the sensor in the machine construction and detector produces the control signal to the different operating part of machine.Or rather, this controller 80 comprises a data importation 81, in order to handle varying input signal, a data conversion portion 82, amplify and A/D conversion and a data processing section 83 in order to signal, carry out the signal processing in order to the arithmetical operation be scheduled to and according to the input data.According to the signal that data processing section 83 is handled, controller produces and is used to control each working portion, as the control signal of hydraulic actuator and control valve.These control signals D/A conversion back in data transaction part 84 sends to working portion by data output unit 85.
Therefore, the signal that constitutes load cell 55 generations of soil charging measurement mechanism 50 is handled in controller 80 according to default mixing ratio, generate a control signal that is used for motor 46, with the quantity delivered that adjusting comes the soil improvement material of the interpolation of feeding part 32 self-quantitatively, the quantitative feeder 42 of the quantitative feeding part 32 of this Motor Drive additive hopper 30.Simultaneously, according to the signal from load cell 55, this controller 80 also produces a control signal that is used for hydraulic motor 70, with the rotating speed of control oar blade type blender 64, the oar blade type blender 64 in this fluid motor-driven soil treatment groove 60.
Various operational datas in the soil treatment work all are stored in the internal storage 86, and the content in this internal storage 86 can be downloaded by I/O processor 87, for example, downloads in the personal computer 88, and compiles by predetermined algorithm at this.The data of compiling be stored in one with external storage 89 that personal computer 88 links to each other in.Like this, the various data of each soil treatment work send in the personal computer 88, so that store and management.
In this respect, in order to increase the reliability of soil treatment, hope stores operational data according to the order of the step of being taked in each soil treatment process, perhaps store with other suitable form, assesses so that can analyze with the effect to the specially treated carried out afterwards.Particularly, need to store soil aggregate data and the soil improvement material of employed interpolation and the mixing ratio data of soil of single treatment.These mixing ratio data should be time series datas.For this reason, controller 80 is configured in memory 86 with the sequential that to be the basis store the rotary speed data of the motor of the output signal data of the load conveyer 55 of soil charging measurement mechanism 50 and quantitative feeder 42.The soil that can provide interpolation like this improves the accurate data of the mixing ratio of material and soil.In fact, improving soil forms in soil treatment groove 60.In this soil treatment groove 60, the soil of soil and interpolation improves material under the mixing and charging effect of oar blade type blender 64, mixes mutually and transmission simultaneously.Like this, controller preferably should be arranged to change according to the viscosity of pending soil the rotating speed of oar blade type blender 64.For this reason, for writing down all working data of each soil treatment, this controller is configured to also can gather the rotary speed data of oar blade type blender 64.
After finishing a soil treatment job, these operational datas can be downloaded in the personal computer 88 that links to each other with the I/O processing section 87 of controller.As previously mentioned, can be stored in the external storage device 89 that links to each other with personal computer 88 with the operational data that compiled handling, for example on a long-time data recording equipment, as flexible disk (-sc), photomagneto disk, storage card or the like, to be used for post analysis and assessment and the condition of work of handling the correlation of attributes of soil.
The limited length of soil treatment groove 60.However, the soil of soil and interpolation improves material still can evenly be mixed, and the length through soil treatment groove 60 is sent to outlet 63 from import 62 simultaneously.Like this, the vehicular soil processing machine that preparation of the present invention is used for small-sized soil treatment field should be able to change little curved when mobile handling, and its structure should be very compact and size is little simultaneously, is transported to another and handles so that handle the field from one.The size of soil treatment groove, the particularly length of soil treatment groove the size of entire machine is had very big influence, and the soil treatment groove have occupied the major part of soil processing machine.Certainly, soil treatment groove 60 can not be reduced to size the degree of its soil treatment ability of sacrifice or efficient.
Consider the various viewpoints in front, what override was considered should be the quality of handling soil, in other words, is the ability that the soil improvement material of soil and interpolation is mixed into gratifying degree.Quality is in the scope that can tolerate the time, and the length of soil processing machine should shorten, and improves its soil treatment efficient with this.In this respect, the structure of oar blade type blender 64 and the relation between the mixing efficiency are studied.Each oar blade type blender 64 all have a plurality of blades 66 be contained in rotating shaft 65 around.For the material in the transport process groove 60 when mixing, blade 66 all is positioned on the axial spirality intervening portion of rotation.
In specific embodiments shown in Figure 19, staggered with an angle of 90 degrees each other around the blade PD of the rotating shaft RS of oar blade type blender PM with helix.Therefore, an axial blade pitch P has been determined at the interval every between the blade PD of four positions on the helix.The position of blade PD on the rotating shaft RS of two oar blade type blender PM is axially staggered with 1/4 blade pitch P each other.Therefore, the blade PD that is contained on the two adjacent rotating shaft RS faces each other with little gap relation, and the axial space position is then corresponding with blade pitch P.Thereby, when from rotating shaft RS axially see or when the direction of transfer of oar blade type blender PM was seen, the blade PD on two rotating shaft RS was overlapping on the blade pitch position, is separated from each other on the centre position.
During oar blade type blender PM running, in treatment trough 60, the processed material in the rotating shaft RS outside is scooped up and is upwards thrown away in the zone that the blade PD of two rotating shaft RS leaves mutually, and that part of material of upwards being thrown away is pushed downwards subsequently, and enters in blade PD moves relative to each other process in the space between the two rotating shaft RS.When processed material moved downward, under the effect of blade PD and mix, this blade PD acted on the processed material towards the lap position motion and from opposite side.That is, from the position of mixing efficiency, the mixing efficiency at middle body when material is processed is the highest, and this blade PD that locates two rotating shafts arrives the lap position.
After processed material being joined treatment trough and with oar blade type blender PM it being mixed and on direction shown in Figure 19 arrow, surpass the transmitting range of being scheduled to, mixability to the treatment trough different piece is measured, and this preset distance originates in initial charge position ST.In case the material of adding arrives predetermined stop place, just oar blade type blender PM is braked to measure the mixability of diverse location.In order to measure purpose, treatment trough section zone is divided into a large amount of regional AR of little sampling in the mode of chessboard, on direction of transfer, divide with predetermined width interval MB, on the direction vertical with direction of transfer then with same preset width at interval ML divide.The regional AR of each little sampling from the horizontally-arranged of dividing with interval MB extracts processed material, to measure the different content that the soil that adds improves material.The result of this measurement as shown in figure 20, wherein axis of ordinates is represented mixability, axis of abscissas is represented the length of treatment trough, and reference letter P 1, P 2, P 2.5, P 3, P 4And P 5It is blade pitch.
Especially as shown in figure 20, it in the blade pitch of oar blade type blender PM 2.5 place, mixability drops between 0.8 to 1 the scope, and that is to say, the content value that the soil that adds among the regional AR of the little sampling of all on the row direction of treatment trough improves material much at one.Even blade pitch increases again, mixability also be can't see increase basically.
By above-mentioned result of the test, can prove, if the distance of oar blade type blender transmission processed material is greater than 2.5 times of blade pitch, consider the difference of soil characteristic, preferably greater than 3 times of blade pitch, the soil of soil and interpolation improves material is mixed into intimate satisfaction equably with regard to the oar blade type blender of the enough minimum lengths of energy degree.Therefore, blade 66 is arranged to three circulations around each rotating shaft 65 of oar blade type blender.That is the import 62 of treatment trough 60 and to export that distance between 63 is set to approximately be three times of blade pitch P.This setup provides and the soil of soil and interpolation can have been improved the minimum length that material evenly is mixed into the treatment trough 60 of enough degree.In addition, from the treatment effeciency position of treatment trough 60, the external diameter of blade 66 preferably is approximately equal to blade pitch P.In brief, the compact form that the soil of soil and interpolation can be improved treatment trough 60 that material mixes with gratifying efficient is that the length overall of treatment trough 60 is blade pitch P of three times, is three times of blade 66 external diameters simultaneously.When arranging like this, treatment trough 60 can be reduced to minimum length,, can reduce size generally that is, becomes compact form.Thereby, can reduce the length overall of soil processing machine, and make it change the little transportation of bending and be convenient to easily.
About the mixing efficiency in the treatment trough 60, it is that character with processed soil changes.When the length of treatment trough 60 reduces as described above, evenly mix processed material and can become difficult.Particularly when processed soil contained large quantity of moisture, its viscosity was understood corresponding increase, and the soil that is difficult to add improves material and evenly sneaks in the processed soil.On the contrary,, keeping stablize hybrid working and improving material at the soil that makes soil and interpolation and fully react and to meet difficulty when forming the soil product of crumbled structure, particularly with lime during as the soil improvement material that adds if moisture very little.So, in treatment trough 60, to carry out soil in order stablizing exactly and to improve processing, the water content that need regulate processed soil to a certain extent.In this respect, the water content in the processed soil had better not surpass 40%, but is greater than 30%.Therefore, before processed soil is thrown into treatment trough 60, its water content is regulated.Particularly, when the water content in the processed soil greater than 40% the time, by sneaking into dry ground or lime it is adjusted to percentage less than 40%.On the other hand, when the water content of processed soil less than 30% the time, can before soil enters treatment trough, increase its water content by spreading water.
In the aforementioned embodiment, for the mixing ratio that keeps additive material and processed soil is constant, the quantitative feeder 42 of soil hopper 20 and additive hopper 30 is opened in the top of the charging conveyer 10 that has soil charging measurement mechanism 50.In this respect, shown in Figure 21 is an available arrangement, and it can also control the mixing ratio of additive material and the processed soil handled exactly in treatment trough 60.
Or rather, at this moment, treatment trough 60 is provided with a big opening 60c on its anterior end face, and the soil that plays a part soil and interpolation improves the charging aperture of material.Soil hopper 20 is positioned at the place ahead of treatment trough 60, and additive hopper 30 be positioned at the soil hopper the back and with the soil hopper at a distance of a preset distance, the opening of its quantitative feeding part 32 is towards treatment trough 60.
The swept volume of oar blade type blender 64 revolutions in the soil treatment groove 60 is to be decided by the quantity of the oar blade type blender 64 in the soil treatment groove 60 and the quantity and the working surface area that are installed in the blade 66 on the rotating shaft 65.Therefore, the soil quantity delivered can take advantage of total work volume of oar blade type blender 64 to determine by rotating speed.On the other hand, additive hopper 30 is provided with quantitative feeder 42, and its quantity delivered can be by motor 46 controls.Therefore, rotate with constant rotational speed if drive the hydraulic motor 70 of the rotating shaft 65 of oar blade type blender 64, soil just can transmit by soil treatment groove 60 with constant flow rate.For this reason, soil directly enters into treatment trough 60 with constant flow from soil hopper 20, this soil hopper can store unnecessary soil, and but these unnecessary soil are to have thrown into the soil hopper that part that has surpassed the soil conveying capacity of oar blade type blender 64.In addition, treatment trough 60 is provided with door 75, with restriction soil conveying capacity.At this moment, the soil quantity delivered depends on the rotary speed of hydraulic motor 70.In order steadily effectively to mix and to transmit soil, wish that this 75 residing position can cover the blade surface that faces about 20% or more.
The lower open end of the quantitative feeder 42 of additive hopper 30 is positioned at the downstream of door 75.That is, as shown in figure 21, at this moment treatment trough comprises three zones, that is, and and soil feed zone Za, additive material feed zone Zb and soil and additive material Mixed Zone Zc.Under this setup of treatment trough, by making hydraulic motor 70 and motor 46 with constant desired speed running, the soil that can control interpolation exactly improves the mixing ratio of material and processed soil.
The rotating speed of hydraulic motor 70 may produce fluctuation because of the variation of loading condition.For example, the loading condition of the hydraulic motor 70 of driving oar blade type blender 64 changes with the amount of the unnecessary soil that store in the soil hopper 20.That is, the rotating speed of hydraulic motor 70 produces fluctuation with the variation of the amount of the soil that stores in the soil hopper 20, and this soil hopper receives soil off and on and supplies with.In addition, the variation of resistance is exactly the resistance of composite material in treatment trough 60, also causes the loading condition of hydraulic motor 70 to fluctuate.Therefore, add the variation that the additive quantity delivered of treatment troughs 60 should be taken place along with hydraulic motor 70 rotating speeds under the fluctuating load situation and change from additive hopper 30.By changing the additive quantity delivered according to the soil conveying capacity by this way, because soil is to transmit continuously by treatment trough 60 under the mixing of oar blade type blender 64 and transmission effect, so the soil of interpolation improves material and always sneaks into processed soil with fixed proportion.For this reason, the rotating speed of motor 46 is regulated with the change in rotational speed of hydraulic motor 70.
Figure 22 shows is one for this reason and the mixture control assembly of design it comprises controller 80, and this controller 80 is provided with a mixing ratio setting section 80a and a motor control section 80b.Mixing ratio setting section 80a comprises an input unit, is used to import the soil that will add and improves the proper mixture ratio that material is sneaked into processed soil.According to the mixing ratio of mixing ratio setting section 80a input, controller is calculated the rotating ratio of motor 46 and hydraulic motor 70.By speed probe 81, motor control section 80b receives the tach signal of hydraulic motor 70, the i.e. tach signal of oar blade type blender 64.Because depend on the rotating speed of oar blade type blender 64 by the soil conveying capacity of treatment trough 60, rotating signal outputs to the servo circuit 82 of motor 46, the additive quantity delivered of the quantitative feeder 42 of this Motor Control additive hopper 30 as the servo control mechanism control signal.
The additive quantity delivered of the quantitative feeding part 32 of additive hopper 30 is by the rotating speed decision of motor 46, this Motor Drive rotating shaft 43.Therefore, when the rotating speed of hydraulic motor 70 changes, promptly, when the soil conveying capacity of oar blade type blender 64 changes, the signal that controller 80 just sends according to speed probe 81, soil improvement material and the rotating speed of processed soil conservation predetermined mix that calculating is sent as an envoy to and added than required motor 46, and the rotating speed of motor 46 changes according to the signal that controller sends, and change with this rotation speed change with hydraulic motor 70.Therefore, no matter how the rotating speed of hydraulic motor 70 changes, can both make the soil of processed soil and interpolation improve material and keep the mixing ratio of being scheduled to consistently.
