Device for vehicles for spreading Clay materials

For this application the priority from the Swedish application No. ₀ 12 711/62 tom 27 «11 · 1962 is claimed«

since "water can freeze quickly, so that the water sole on the street is already frozen" when it picks up the sand, and the sand cannot be set in the waeeerechioht. If very copious amounts of water on the ground or the street be sprayed »the freezing does not take place ο quickly, but instead the tank is emptied too quickly.

The invention lies; based on the task of eliminating the above »Haohteile and creating a device o through the danger of too early freezing of the water is eliminated even in the most severe frost ▼ 0111g, and by which the water « consumption is kept to a minimum.

Bas freezing of the water at too early a stage is prevented by the present invention by the feature that a heat prevention by Since * the vehicle's exhaust system is formed, the exhaust system is based on a larger or smaller one Extent in, close to or next to the water tank and / or in pipes or lines leading from the Lead the tank to the water outlet »

By means of such a heating device, the temperature of the water can be practically constant and at no cost to be kept at a higher value bad and water consumption is a minimum

The water tank can be used as a boiler or with a steam « be designed to produce water on the ground or the street in the form of steam a strong heat effect is achieved on the road, as the road will consume the heat of evaporation ο A very strong adhesion of the sand particles is achieved through subsequent freezing «,

The water tank can either be emptied exclusively by gravity or additionally by means of compressed air _p which is introduced into the tank through a line from an air pump »which is connected to the vehicle engine» The line advantageously has a valve to regulate the flow rate =

Sas output or discharge pipe 5 for the water can be performed in close proximity to the exhaust pipe 9, so that the heat of the exhaust pipe also can be effective outside the tank 4

In order to maintain the water output from the tank 4 in a controllable and reliable manner, a pipe 10 can be connected to this tank be led? to feed it with compressed air *

The controllability can be achieved by a valve 11 that is built into the pipe or line ο The compressed air can be supplied by a container 12, for example any pressure vessel _e which can be replaced when it is empty ο As Optionally, the container 12 can be fed with compressed air from a pump 13 which is driven in a suitable manner by the vehicle engine.

The containers 4 and 12 for water or compressed air can be arranged in any desired manner in the vehicle or be stored, for example under the tipping body or under the floor of the driver's cab “like indicated in the drawing

The dispenser 6 for the water or the steam can be arranged in the same way in different places in the vehicle and in different positions in order to obtain a spray effect in desired directions, the device can be adjustable, so that the direction of the spray jets can be changed according to desires and circumstances »For this one For this purpose, the tube can be 5. flexibly or articulated be that steam or water are at least partially sprayed against the falling sand so that the Sand is moistened or wetted before it touches the ground »

Sand dispensers other than that in Fig. 1 shown tilt mechanism can be used *

In this way, special external links which are mounted on rotating shafts »can be used. This ensures uniform sand distribution «The vehicle can also be of a different type than the truck shown», for example to accommodate a considerably larger water tank _e

The waeserauegabvorrichtung 6 is suitable arranged behind the rear wheels of the vehicle »

The invention also has means depending on the temperature of the environment "to control the heating of the water in accordance with the ambient temperature" since the water temperature rises in accordance with a falling temperature of the surrounding air and vice versa. "If the water temperature is too low, the water becomes that is sprayed freeze too quickly and have no side ρ to melt or heat the road enough ρ to fix the sand particles. If the water temperature is too high "will", too much snow and snow on the road melted _f and there "water can run off the road" so that an inadequate base is left for the inevitable binding of the sand grains or particles.
