Description

450 584 2 south processing in the flow that lumps are broken and stones t o m crushed. The large active moving surface provides great machining capacity and thus low risk of clogging.

The characteristic of the method according to the invention is that in that flow filling material, which is to be spread, a oscillating surface built up is introduced of rods. The surface is made to oscillate around any axis of the known sweet with a reciprocating motion. The pendulum force is so great that in relation to the shaft dimension it is able to twist the same at the end points or bend the same at its center lumps would prevent the rotation of the shaft.

Due to this design, material is moved from storage on two rods to the edges of the container where the rods expose lumps and also stones for a processed decomposition. The walls of the container constitute die a stiff resistance.

Of the accompanying drawings, Figure 1 shows a cross section through a sand spreader with oscillating discharge table. Figure 2 shows a rust or cage of rods connected by a shaft over flat sectors.

These and the axis are shown without bars in Figure 3. In Figure 4, the replaced by spokes.

Description of a successful embodiment.

A common type of sand spreader uses oscillating discharge tables.

Others have rollers, bands or screws for dosing. Finally available types of diffusers which allow the dispersion to take place with a plate but a spoon from a storage vessel with a triangular cross-section. Distinctive for diffusers it is thus often that a storage vessel, 1 in figure 1 has triangular cross-section. At the bottom of the vessel there is a discharge device, as exemplified here by the oscillating table 2.

The oscillation takes place around an axis 3. In the pre-red vessel there is an axis 4 stored in a known manner and most easily in the ends of the vessel. The shaft 4 brought to commute back and forth in a known manner, which here exemplifies is fixed with the rod 5 attached to the shaft 4. The rod 5 is in the figure travel through a hole in the dispensing table 6. Around the forearm there is seals against the discharge table 2 in the form of a resilient seal 7. A rust or cage of thin rods 8 is connected with the oscillating shaft 4. The incision made through a spreader or its anterior vessel contains the oscillating shaft ' 3 -450 584 driving rod 5, which is also shown in other figures where the break or the cage is lifted clockwise. In Figure T, the spreader's pre-red vessel is for single hero plot empty. During operation, it is filled with eg sand, in which the struts 8 oscillate back and forth about the shaft 4. This driving takes place on known sweet, which is exemplified in the figure the coupling to the discharge table 2. Other external couplings fall also within the scope of the invention if the commuting is periodic.

Figures 2 and 3 show both the cage or the rust and the the ringing of the stoves on sectors. Characteristic of the invention the way is now that the flow of filling material during the passage through the storage vessel processed by a large area derived from a plurality of rods I ' Figures 1 and 2 are the number five, but this is not a feature.

More or fewer rods have shown good results, but for sand- and salt spreaders, a number of 5 to 7 have given promising pickling and stirring of the intended goods. With several rods along and parallel to the reciprocating shaft 4, substantially larger processing of the filling material, which is printed by its own weight down through the diffuser vessel of the spreader. With this major processing and agitation, a safe dosing of sand is achieved on icy roads.

In addition to the better processing and stirring with the shown the break in Figure 2 was obtained due to its construction with long, barrel stiff bars that reduce the risk of clogging when compared with today's common diffusers. The hilly shape causes lumps and possibly stones etc. moved against the walls of the spreader during commuting and the pressure from the filling above, At the wall a efficient processing by force-controlled clamping. There can however, jamming occurs. Due to the small dimensions of the rust sioning occurs a twisting or bending of the shaft or rods so that a stop or breakdown does not occur.

What happens is that either the whole surface is twisted, it is twisted, or bends the shaft 4. By a number of rods come into use a resilient surface was obtained, which can be rotated.

The rotation can be facilitated if the shaft is also made of a small dimension.

However, as shown in Figure 2, the connecting sectors 9 can be made coarse and rigid. Thereby, a good fastening base was obtained partly for the rods 8 partly for shaft 4! You get a swivel cage or part of it, 450 584 4 In the figures, the break has been given an angular range of about 900 off a circular straight cylinder. This is not a feature.

The rust can in cross section have the shape of an ellipse or part thereof or other curved surface. The rust can also be given a double effect by forming a closed cylinder with any arbitrary cross-section.

However, this entails more work in production. The professional chooses here it for fillings, storage vessels and geometric design most appropriate design. Although the design with flat sectors to support the bars 8 has shown both functional and production technical advantages it has proven beneficial for some types of fillers to store the rods 8 on curved bands 11, which are fastened in a known manner at resilient spokes 10. This is shown in Figure 4. There only the fastening supports are shown in the same way as the sectors in figure 3.

The rods 8 can also be rotated here so that the rust is twisted and now the shaft 4 can be made thicker as it is turned less. This is an advantage if the filling magazine 1 has a high height and the pressure in the container is large. ' The method according to the invention thus consists partly of the introduction of a surface with several rods 8 and the introduction of resilience such that the rods of the perforated surface can be rotated. Detail- dimensioning of input shafts and rods is such that any professional can handle.

The drive of the oscillating movement has been obtained in Figure 1 from the output table 2. The number of oscillations is usually synchronized with spreader speed, which is sometimes felt by wheels, which support the spreader. This and other power sources can be known in known ways. moved so that the rod 5 causing the oscillation by other methods brought in swing._In the figure, the opening 6 in the discharge table given larger diameter than the rod. The gap can advantageously be filled with a_ rubber bushing.

The location of the driving rod 5 on the shaft 4 is in the figure asymmetric. Those skilled in the art can judge this, For sand and salt spreaders, it has proven advantageous to perform the break in steel. Other rigid materials can, however, as well come into question when the corrosion or cleanliness hull is different. 450 584 The coupling between spokes or sectors and the shaft 4 can in a ' some cases need to be more elastic island such as a welded joint.

It has then proved to be advantageous to let the connection be done over a bushing with elastic material such as rubber. Such bushings are known to those skilled in the art.

Industrial usability The agitation problem itself is not difficult to solve, the problems caused by foreign objects in the flow such as rocks, boards chains and other. These stop the agitator or cause a breakdown whereby, for example, a breaking bolt can be released. The container must then be emptied and the foreign object is removed, Emptying takes time. After _ an accident must be repaired, which also takes time. If the agitator ceases to function, gaps enter the spread, which can be, for example, dangerous in traffic.

With the present invention, the problems have been solved in one economically reasonably sweet.
