  • the invention relates to a snow loading machine comprising a snow collection chute transverse to the direction of travel of the snow loading machine and movable along the ground, the chute being provided with a screw conveyor for moving snow in the snow collection chute, in the longitudinal direction of the chute, towards a scraper conveyor which is provided at the discharge end of the screw conveyor for moving the snow with the scraper conveyor onto a platform body or other desired collection base, while the screw conveyor is arranged to feed the snow to the scraper conve - or from the side of the scraper conveyor.
  • the aim of the invention is to develop a practical solution for a continuous-drive loading machine, which is applicable to clearing snow in population centres, from thoroughfares as well as from pavements and yards, and by means of which the snow can also be compacted in order to reduce the number of loads driven.
  • the actuator of the scraper conveyor prefferably to be adjustable according to the load on the screw conveyor, whereby the snow is compacted in the desired manner regardless of the type of the snow.
  • the bearing wheel of the scraper conveyor is fitted with bearings to rotate independently at the discharge end of the screw conveyor.
  • the screw conveyor collects the snow and moves it onto an ascending scraper con- veyor.
  • the scraper conveyor discharges the snow either onto the work machine's own platform, a trailer or the platform of a truck travelling parallel to it.
  • the solution does not set limits to efficiency, that is, the device can be made as small or as large as desired and the solution still functions. The only factor to be considered is the efficiency of the device's own or separate working power machine and the readiness for connecting the loading device (hydraulics).
  • the snow can always be compacted as desired regardless of the type of snow.
  • the snow loading machine according to the invention can be applied in a new type of snow loading system for clearing snow from the street.
  • the solution according to the application comprises a comprehensive system for collecting snow from the streets into readiness for transportation on interchangeable platforms to snow tips.
  • the purpose of the preferred embodiment of the invention is to avoid the foregoing drawbacks and to provide a practical snow loading system applicable to population centres, by means of which roads and lanes can be continuously cleared of snow immediately after snowfall, or in wider streets after snow ploughing, and the energy consumption of which is low in relation to the amount of snow loaded and transported. Furthermore, in the system according to the embodiment of the invention, the snow is compacted to reduce the number of loads driven to the tips.
  • the above-mentioned additional purpose of the invention is achieved in accordance with the invention, on the basis of the characteristics disclosed in the accompanying claim 7.
  • Figure 1 shows the snow loading machine according to the invention as a diagrammatic top view and in partial section.
  • Figure 2 shows a cross-section of the machine of Figure 1.
  • Figure 3 shows diagonally from the front a top view of the system according to the invention with the interchangeable platform removed, and Figure 4 shows the same as Figure 3, as seen from the side, with the interchangeable platform in operating position.
  • the snow loading machine comprises a snow collection chute 1 transverse to the direction of travel A of the snow loading machine and movable along the ground.
  • the collection chute 1 is provided with a screw conveyor 2 for moving the snow in the snow collection chute 1, in the longitudinal direction of the chute, towards the bull chain conveyor 3.
  • the snow loading machine formed by these machine parts 1, 2, 3 can be connected to an independently moving motor vehicle, for example a truck or a tractor, or it may be a completely independent machine.
  • the scraper conveyor 3 is arranged to the discharge end of the screw conveyor 2, transversely to the feeding direction B of the screw conveyor.
  • the bearing wheel 4 of the scraper conveyor 3 is fitted with a bearing to rotate independently at the dis- charge end of the screw conveyor 2.
  • the scraper conveyor 3 is preferably a bull chain conveyor, where the scraper plates 7 are attached to a chain 8 supported by the bearing wheels 4.
  • the screw conveyor 2 has a first and a second screw half with a mutually opposite helix direction, whereby when rotating in the same direction, the screw halves feed snow towards the central area of the screw conveyor to which the scraper conveyor 3 is connected.
  • Both screw halves have their own hydraulic driving motors 9 which drive either a drive shaft common to both screw halves (joint drive) or separate drive shafts (separate drive).
  • a conical compacting means 5 for compacting the collected snow at the transfer stage from the screw conveyor 2 to the scraper conveyor 3.
  • the compacting means 5 are comprised of conical sur- faces expanding towards one another, which limit the transporting space of the scraper conveyor 3.
  • a conical compacting means 5 which is formed into a conical surface expanding away from the screw conveyor 2, across which the scraper plates 7 of the scraper conveyor travel in an area where the direction of travel of the scraper conveyor turns on the bearing wheel 4.
  • the conical surfaces of the compacting means 5 also facilitate the flow of snow from the screw conveyor to the scraper conveyor.
  • the conical surfaces support the supporting frame of the bearing wheel 4, on which the bearing wheel is fitted with a bearing.
  • the actuator (not shown) of the scraper conveyor 3 is arranged to be adjustable according to the load. It is thus possible to adjust the speed of movement of the scraper conveyor 3 according to the type and/or quantity of the snow, whereby the compacted pieces moved by the scraper conveyor 3 are always as compact as desired. The more snow the screw conveyor 2 feeds into the space defined by the conical surfaces of the compacting means 5 and the protective casing 6, and the slower the scraper conveyor 3 is moved, the more the snow is compacted.
  • the space between the scraper plates 7 becomes smaller on the straight part of the conveyor compared to the part which travels around the bearing wheel 4, which increases the compacting of the snow.
  • a plough-like snow-guiding means 12 behind which is a protective casing 6 (shown only in Figure 1 and omitted from Figure 2 for the sake of clarity).
  • the protective casing 6 partly surrounds the bearing wheel 4.
  • the direction of travel of the scraper conveyor 3 turns 180° on the bearing wheel 4.
  • the direction of travel turns in the same way at the opposite end of the scraper conveyor (not shown).
  • the compacted pieces are then formed as the screw conveyor 2 compresses snow between the conical surfaces of the compacting means 5 and the protective casing 6 of the scraper conveyor 3.
  • the scraper plates 7 of the scraper conveyor 3, which on the one hand define the size of the compacted piece, on the other hand at the same time move the compacted pieces further to the desired location.
  • the snow loading machine is supported on the ground by support wheels 13 and attached to the shafts 10a of the motor vehicle by links 10b, which are connected to lugs 10.
  • links 10b which are connected to lugs 10.
  • ploughing wings 11 At the ends of the collection chute 1 are ploughing wings 11, the ploughing angle of which is preferably adjustable by means of hydraulic regulating units.
  • the system comprises a snow collection device moving with a motor vehicle 14, the device comprising a collection chute 1 transverse to the direction of travel A, which is provided with a rotatable screw conveyor 2 for moving snow towards the centre of the collection chute 1, where there are compacting cones 5 for compacting the snow mechanically before the snow moves on to a chain-driven scraper conveyor 3.
  • the screw conveyor 2 rotated in the chute feeds the snow collecting in the chute 1 via the compacting cones 5 to the scraper conveyor 3.
  • the scraper conveyor By means of the scraper conveyor, the snow is moved further to an interchangeable platform 15 designed for the purpose which moves with a motor vehicle 14.
  • the speed of the scraper conveyor 3 is adjusted according to the load of the screw conveyor 2 in or ⁇ der to be able to always compact the snow in the desired manner, regardless of the type of snow.
  • the interchangeable platform 15 is adapted to fit between the branches 17 of the body of the motor vehicle 14, when the motor vehicle 14 is reversed.
  • the inter- changeable platform 15 is lifted hydraulically to the operating position by the normal ground clearance.
  • the rails 16 on the sides of the interchangeable platform 15 slide into supports on the body branches 17.
  • an interchangeable platform 15 suitable for common interchangeable platform transport A loaded interchangeable platform 15 is lowered to street level and passed on for further transportation.
  • ploughing wings 11 At the ends of the collection chute 1 are ploughing wings 11, the ploughing angle of which is preferably adjustable by means of hydraulic regulating units.
