Definitions
- propeller agitators for homogenising heterogeneous liquids containing solid particles are known from the prior art. Liquid fertiliser from farm animals is one such liquid, C and normally consists of roughly 90% water and 10% dry matter. In the agitating process, it is necessary for the propeller to reach out to various places in the large fertiliser containers, which are often round, with a diameter of 15 - 30 meters and a depth of-3- - 4 meters.
- the known solution is to construct the propeller agitator as a long rigid element that extends rearward from a tractor, measures roughly 5 - 10 m in Q length and has a propeller at its rear end.
- the mounting to the tractor or to an elevated framework, for containers with high rims that can come to be positioned between tractor and agitator, or to an extension frame, for larger wells with certain rims that may also come to be positioned between tractor and agitator, is such that the agitator can, owing to the articulated design of the mounting, be swung in the vertical ⁇ plane, but not normally in the horizontal plane.
- Vertical motion is customarily achieved by means of hydraulic cylinders, and is used to enable the positioning of the propeller at various depths in the liquid, which is extremely important to the process results.
- the described arrangement has, in heretofore known solutions, comprised both the working,position and the transport position of the agitator, and this has posed a risk and a major problem in connection with transport, mainly on public roads, since the slightest steering adjustment of the tractor results in the propeller end being rapidly thrown out into the oncoming traffic lane, due to the customary horizontally rigid ⁇ mounting of the agitator, and to its length.
- the purpose of the present invention is to provide a special transport position of the propeller agitator that enables fast, safe and comfortable transport in both heavy traffic and narrow passages.
- the solution according to the invention in this respect is presented in the characterising part of claim 1.
- a number of prototypical exemplary embodiments of the invention have been Q produced and found to work exceptionally well.
- the aforementioned articulation should be controlled in some way, e.g. by means of a hydraulic cylinder; moreover, the end positions of the swiveling motion for the working and transport positions should be locked by means of, e.g. bolts and nuts, to ensure reliable agitator function.
- One common way to transfer the power from the tractor power take-off shaft Q spindle to the propeller of a propeller agitator is via a long rotating shaft that runs inside or out along the extending element.
- said shaft must also be articulated, and that it must be possible for the segments to transfer torque to one another via, e.g.
- propeller agitators that are divided into parts that are somewhat swivelable in relation to one another are known in the prior art, but solely for the purpose of improving the possibilities for positioning the propeller; these solutions have resulted in no notable positive effect on the possibilities in terms of 5 transport.
