Definitions

  • the present invention relates to a tool in the form of a snow slush wiper apparatus designed for attachment to a vehicle and to interact with the ground in order to remove snow slush from a road surface, which apparatus includes a main frame for attachment to the vehicle.
  • the slush wiper is made of rubber, the ability of the wiper to follow the unevenness of the road surface, such as wear tracks in the road surface resulting from use of tire studs, is not particularly well. Much of the slush continue to escape past the rubber strip and is left behind in the roadway.
  • One primary object with the invention has been to provide a tool which is better able to wipe off slush from the road surface so that less amounts of salt are necessary to remove or melt the remaining snow slush.
  • a tool or apparatus of the introductory said kind which is distinguished in that at least one row of individual rubber blades is secured to the main frame, which row of rubber blades extends transversal to the driving direction when in use, preferably angled relative to the driving direction, which rubber blades have individual, limited and resilient freedom of motion, said resilient motion tending to bring the rubber blades back to a position of origin.
  • each rubber blade has its individual and independent, limited freedom of motion in the plane thereof. This means that the motions of the blade are limited to up and down, and a limited rotation or turning about an axis extending centrally and perpendicular to said plane of the blade. This describes in closer detail a way how to get the rubber blade to follow the unevenness of the road surface, also wheel tracks resulting from stud tire use and wear.
  • each rubber blade also can have individual and independent, limited resilience in a direction substantially perpendicular to its plane.
  • each rubber blade is overlappingly offset relative to each other in the longitudinal direction of a row. By this embodiment the freedom of motion of each single blade will increase compared with if they should be placed in line and close adjacent to each other.
  • each rubber blade may include armoring embedded into a rubber matrix. The armor can be cords or strands of a type similar to those used in car tires.
  • each rubber blade can be secured to a retainer which is spring-loaded secured relative to the main frame.
  • each retainer may include two cantilevered arms having a support plate secured between them, which support plate, in turn, carries the rubber blade and each
  • cantilevered arm includes a slit for receipt of a frame part in the form of a rod body.
  • the spring load can be provided by means of a leaf spring and a seat, the leaf spring being introduced into respective slits in the cantilevered arms and abuts the lower end of the slit, and, in turn, the seat abuts in a pretensioned way against the lower side of the rod body.
  • the rubber blades can exert pressure against the ground by virtue of the specific weight of he slush wiper apparatus, possibly with the addition of supplemental force from an actuator, such as a work cylinder.
  • the slush wiper apparatus can be elevated and lowered by means of at least one actuator, such as a work cylinder.
  • the tool can be mounted at different locations on a vehicle.
  • the tool can be mounted in the middle below a snow truck, alternatively just in front of a salt sprinkler of a vehicle.
  • the tool can also be mounted between a plough and the front end of a vehicle if the space allows.
  • Fig. 1 shows in perspective view, inclined from above, a complete tool according to the invention and in an embodiment having three rows of snow slush blades,
  • Fig. 2 shows in perspective view, inclined from above, the main frame of the tool
  • Fig. 3 shows an end view of the tool according to figure 1
  • Fig. 4 shows a detailed view of the tool according to figure 1 .
  • Fig. 5 A shows in perspective view, inclined from above, a row of slush blades designed to be mounted to the main frame shown in figure 2,
  • Figure 5B shows the same as in fig. 5A, but viewed from above,
  • Fig. 6A shows in perspective view an individual slush blade unit
  • Fig. 6B shows an end view of the slush blade shown in figure 6 A
  • Fig. 6C illustrates the motion of freedom in rotation the slush blade possesses
  • Fig. 7 illustrates the motion of freedom up and down the slush blade possesses
  • Fig. 8 shows a tool mounted to a schematically illustrated vehicle.
  • FIG 1 shows a first embodiment of the tool 1.
  • This embodiment has three rows of slush blades 2 placed after each other and somewhat offset relative to each other. They are offset relative to each other because the tool 1 is angularly mounted in relation to the driving and longitudinal direction of the vehicle, see figure 8.
  • the tool 1 is set at an angle between 20 to 40 degrees relative to the driving direction and such that each row end projects on both sides of the vehicle and the ends are located substantially in line in parallel to the longitudinal direction.
  • the number of rows, one or more is a choice to be taken with regard to the conditions of the road surface and the circumstance about the slush to be removed.
  • the tool 1 will rest on the ground by its own weight.
  • the shown embodiment with three rows weighs in the order of magnitude 800kg which provides a good pressure against the ground.
  • one or more actuators (not shown), such as a work cylinder, is arranged between the chassis of the vehicle and the tool.
  • the actuator or actuators are able to increase substantially the pressure of the slush blade against the ground, which is necessary on worn road surfaces having deep wheel tracks.
  • the tool 1 can be elevated or lowered in order to be lifted and free from the road surface when not in use, and lowered when the tool is to be used to remove slush.
  • Fig. 2 shows the main frame 3, which is to support the three rows of slush blades 2.
  • the frame has a number of braces 3 a, here shown six individual pieces, extending transversely of three support rods 3b.
  • the braces 3a are welded to each individual support rod 3b to form a rigid frame structure 3.
  • Two of the braces 3 a' are especially designed in order to be prepared for mounting means for attachment to a vehicle and actuators.
  • fig. 3 and 4 For the more detailed description of the tool construction, reference is made to fig. 3 and 4.
  • fig. 3 the tool 1 is shown from one end, while fig. 4 shows the same, but somewhat in perspective view inclined from above.
  • the slush blades 2 themselves are placed in a line, but are somewhat overlapping and offset relative to each other.
  • Each slush blade 2 is individually secured to a respective retainer 4 or a mounting bracket 4.
  • Each mounting bracket 4 is in turn secured to a support rod 3b, but is not fixed to the support rod 3b.
  • At each end each support bracket 4 has a frame 4' encircling the support rod 3b, which can be opened both for first assembly and later replacements.
  • FIG. 5 A and 5B illustrate more clearly how each support bracket 4 is mounted relative to the support rod 3b, both regarding the overlap and how they are offset relative to each other. Further, the support brackets 4 are prevented from sliding along the support rod 3b by smaller protrusions, such as the lug 3' illustrated in figure 2. Some motion of freedom, however, they may have.
  • Fig. 6A-6C show the support bracket 4 in closer detail and in several perspectives. Additionally, they show a somewhat different design of the support bracket 4, or retainer 4.
  • Each retainer 4 includes two cantilevered arms 4a, 4b having a support plate 4c secured therebetween.
  • the support plate 4c carries in turn the rubber blade 2.
  • Each cantilevered arm 4a, 4b includes a slit 4d for receipt of the support rod 3b. As indicated above, the slit 4d is closed by a cross-member 4e that is secured by means of screw connections.
  • Fig. 6A shows in closer detail how the spring load is provided by the aid of a leaf spring 6" and a seat or saddle 6' as mentioned above.
  • the leaf spring 6" is introduced into respective slits 4d in the cantilevered arms 4a, 4b and is abutting the lower end of the slits 4d, and the saddle 6' is in turn placed pre-tensioned against the underside of the support rod 3b. Naturally, this may be arranged differently if desired.
  • Fig. 6B shows this right from the side.
  • Fig. 6C illustrates by means of broken lines possible motions of the slush blade 2 influenced by the ground that the tool 1 is pulled over.
  • the pulling direction is normally to the right hand side of the figure sheet, such that the slush blade 2, in a way, is dragged relative to the support rod 3b (and is not pushed).
  • the figures also show that the slush blade 2 has a centrally located slit S, which provides some motion of freedom to each half of the slush blade 2 relative to each other, which still more increases the ability to follow and contact the entire width of the road surface.
  • Fig. 7 illustrates in closer detail how the leaf spring 6" and the slush blade 2 can move in respect of the saddle 6' when the slush blade 2 is exposed for unevenness in the ground causing approximately vertical motions.
  • the rubber blade 2 exerts pressure against the ground in virtue of the dead weight of the tool 1. It will often be advantageous, and actually necessary in many situations, to exert additional pressure from one or more actuators, such as a hydraulic work cylinder.
  • the tool 1 can be elevated and lowered by means of at least one actuator, such as another hydraulic work cylinder.
  • each rubber blade has individual and independent, limited resilience in a direction substantially perpendicular to its plane. This is a natural property of rubber.
  • the rubber can have embedded armoring, such as cords or strands in a car tire and balata, for example.
  • Fig. 8 shows an alternative tool 1 ' as the tool typically will be mounted to a
  • FIG. 1 schematically illustrated vehicle K.
  • This embodiment has two rows of slush blades 2, the rows being substantially offset relative to each other, but also a variant where this offset feature is adjustable. Each row does necessarily not need to be equally long.
