Description

Levelling assembly
The present invention relates to a levelling assembly for use as an implement of construction or agricultural machinery provided with hoisting gear, the levelling assembly comprising a secondary frame, and side, front and rear blades connected thereto.
An assembly like this is used for spreading soil or contouring the surface in construction and maintenance of roads and yard areas.
It is previously known to use different single-blade ploughs, multi-blade graders, or levelling assemblies dragged by a tractor and provided with one or more blades contouring the surface of the road. The prior art, however, has many drawbacks.
For example, with single-blade apparatuses the finish is rough, and when inclined, such apparatuses lose their steerability during heavy grading. Multi-blade apparatuses, in turn, are too long and cumbersome, and so are road graders, whose purchase price is usually also quite high. The use of such long apparatuses also requires rather much space, i.e. the known apparatuses are very difficult to use in a narrow space.
In addition, large amounts of soil are difficult to move with the known apparatuses. The soil accumulating on the cutting and ploughing blades of the apparatuses tends to discharge laterally from the apparatus, providing a dirt wall on the roadside. A dirt wall like this prevents water from draining away from the roadway and hampers the use of the verge.
The object cf the present invention is to eliminate the drawbacks of the prior art, and to provide a levelling assembly which is simpler and easier to use but with which a good spreading result is achieved. The levelling assembly according to the present invention also enables simple adjustment of the effective width and height.
The object is achieved with a levelling assembly that has the characteristics defined in the claims. More particularly, an assembly according to the invention is primarily characterized in that a framework is rotatably fastened to the secondary frame, and that body portions of the rear blades are immovably attached to the secondary frame and body portions of the side and front blades are immovably attached to the framework, which enables rotation of the rear blade essentially vertically in relation to the side and front blades.
The levelling assembly according tc the invention is pushed, unlike many other known levelling assemblies or spreaders. This makes it possible to use any suitable construction or agricultural machinery that is provided with hoisting gear. A shovel loader or a biggish tractor provided with hoisting gear is particularly well-suited for the purpose. A levelling assembly is installed in place of the shovel in the machinery. The driving power of the actuators of the levelling assembly is preferably generated by the hydraulics of the machine.
Considerable advantages are achieved with the levelling assembly according to the invention. For example, the assembly is quick and easy to install in construction or agricultural machinery. It is also easy to use since it is placed in front of the machinery. It can be easily steered on narrow roads and even to narrow places, especially when framework-steered machinery is used. The structure of the levelling assembly also enables the use of great pressing and push force without impairing the steerability of the assembly. On account of the side and front blades, the assembly according to the present invention has a soil grinding and mixing effect . The structure of the assembly also allows storage of soil in the assembly for moving of material, whereby soil moves with the assembly while the rear blade levels the surf ce.
In addition to the fact that the rear blade of the levelling assembly can be moved vertically in relation to the blades of the front part, the entire levelling assembly can also be rotated about its longitudinal axis, and the positions of the side plates in the rear blade can be changed. On account of the diverse adjustments, soil can be moved exactly to the desired point . In the front part of the levelling assembly, blades are positioned in pairs in an inclined position symmetrically in relation to the longitudinal axis of the assembly. Because of this, the lateral forces affecting the assembly eliminate one another effectively.
The structure of the assembly according to the invention is simple, and so the purchase price is low. The assembly also needs little service, and so its operating costs are low also. A levelling assembly is an efficient and quick tool in the maintenance of gravelled roads or yards and other such areas, but it also facilitates the construction of temporary roads and winter roads . When a levelling assembly is kept in the site together with the construction or agricultural machinary, it can be quickly fastened as an implement to the machinery for levelling and contouring purposes.
In the following, the invention will be described in greater detail with reference to the attached drawings, in which fig. 1 is a side view of a levelling assembly with the rear blade down, and fig. 2 is a front view of a levelling assembly lifted by construction or agricultural machinery. The figs, show one preferred embodiment of the levelling assembly. The assembly comprises a front part 1 and a rear part 2, the rear part comprising a secondary frame 3, a rear blade 4, and a jointed fixing plate 5 provided with lugs, known per se, for fastening the levelling assembly to construction or agricultural machinery 6. The secondary frame 3 of the rear part is rotatably fastened with joints 7 and 8 to a framework 9 located in the front part, which enables the rotation of the front part 1 about the transverse axis of the levelling assembly. Preferably two side blades 10 and two front blades 11 are immovably attached to the framework 9. The blades are located in the front part symmetrically on both sides of the longitudinal axis of the levelling assembly such that the front blades 11 join at the front end of the levelling assembly, forming a sharp point, and that between the side blades 10, at the end close to the rear blade 4, there remains an opening 12 for transferring of soil . The blades of the assembly comprise a body portion and a cutting edge. The blades are attached to the levelling assembly at their body portions, and the cutting edges are adjustable and/or removable.
The distance between the side blades 10 and the rear blade 4 is sized such that as the front of the rear blade fills up, the soil closes the opening 12 between the side blades 10, and when the opening is closed, soil will be stored between the blades 10 of the front part 1.
The height of the rear blade 4 in relation to the side 10 and front 11 blades of the front part can be adjusted with control means 13 fastened to the secondary frame 3 and the framework 9 with joints. The rear blade is detached from the working surface and lifted above the lower surface of the blades of the front part e.g. by means of hydraulic control means. For example, the thickness of the soil layer spread by the levelling assembly on the surface of the road can hereby be controlled.
Since the secondary frame 3 is rotatably attached to the fixing plate 5 and further to the construction or agricultural machinery 6, the levelling assembly can be rotated about its longitudinal axis by means of the preferably hydraulic control means 14 located in the secondary frame. The slopes of the road or yard area can thus be easily made to incline at a desired angle, using the levelling assembly. Also, the verges of the road can be made to incline at a desired angle simply by changing the position of the levelling assembly of the invention. Lateral plates 15 are attached to the outer blades, such as rear blades and side blades, of the levelling assembly. They enhance the guidance of the soil to the levelling assembly and storage thereof in the assembly during the working process. The lateral plates can be arranged to be adjustable, and by adjusting the angle between the lateral plates and the blades, it is thus possible to control e.g. the effective width of the levelling assembly and the capacity of the assembly to accumulate material . Control wheelwork 16 can be attached to the levelling assembly, e.g. to the front part 1 of the assembly. Wheels 17 of the control wheelwork are arranged revolvingly on a transverse support shaft 18 such that they can carefully follow the movement of the levelling assembly and the contour of the area to be levelled, thereby facilitating the use of the assembly by supporting and controlling it in the vertical direction. The wheelwork 16 is preferably arranged to turn in relation to the longitudinal axis of the levelling assembly, whereby the position of the assembly can be selected freely, independently of the wheels following the contour of the area under treatment. The controllability of the wheels can be further improved by realizing a clamping bar 19 of the wheelwork as a continuable bar, whereby information about the contour of the area to be levelled will be transmitted sooner to tne levelling assembly and further to the construction or agricultural machinery controlling the assembly. In a levelling process, the side 10 and front
11 blades of the levelling assembly detach and grind soil from the working surface, such as road or yard area, under treatment, and tranfer it to the rear blade 4, simultaneously levelling the surface. Soil hereby accumulates in the area between the rear blade and the lateral blades. As the accumulated soil reaches the opening 12 between the side blades, the opening will close and soil will start to accumulate m the area defined by the side blades 10, instead. The levelling assembly can thus accommodate a large amount of soil, which can be utilized during the levelling or moved somewhere else.
The levelling process proceeds such that the rear blade 4 is gradually detached from the surface under treatment, and soil accumulated in front of the rear blade is thereby spread e.g. on the surface of the road. The height of the rear blade can be adjusted in relation to the front blades with the control means 13 , and the thickness of the layer to be spread can thereby be controlled. When the rear blade is maintained at the same height as the blades of the front part, it is possible to move large amounts of material with the levelling assembly even for long distances .
When the cutting edges in the body portions of the blades or the blades themselves are arranged to be adjustable, the adjustments required by the contour of the road can be set in the levelling assembly beforehand, whereby the road can be levelled on its entire width at one go. The levelling assembly according to the invention is preferably arranged to operate hydraulically, whereby its driving force is generated by the hydraulics of the construction or agricultural machinery 6 in a manner known per se, and the hydraulic means are also controlled by said hydraulics either manually or automatically. Hydraulic hoses are attached to the hydraulics of the construction or agricultural machinery by a bayonet connection in a manner known per se. To make the working process more efficient, it is possible to arrange a rod potentiometer, ultrasound or laser means to regulate the thickness of the layer to be levelled with the levelling assembly. The thickness of the layer or the height of the surface is then controlled automatically by the hydraulics of the construction or agricultural machinery.
The invention is not limited to the above embodiment but can be modified in many ways within the scope of the inventive idea defined in the attached claims.
