DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a rotating liquid distributor used together with a spreader for liquid manure, water or other liquid, possibly including other compounds.
Such rotating liquid distributors for the distribution of liquids, possibly a liquid with a powder or other coarser particles added, such as liquid manure from livestock and possibly mixed with additional liquid, for instance water, are known from SE-8505255-3 (publication No. 457.404). The rotating liquid distributor comprises, according to the publication, a round container divided into compartments which make up a wreath, and which has outlet openings from each compartment connected to outlet pipes or hoses. A rotor with outlet nozzles is centrally positioned in the container and is operated by means of outflowing hydraulic pressure from the nozzles, so that liquid is evenly distributed to the compartments. When the liquid distributor is in a slant position, the liquid will collect in the compartments and possibly flow over the inner, lowest wall of the compartments, at the greatest distance from the outlet openings. This may cause uneven distribution of the outflowing liquid through hoses/pipes to the spreader boom or hoses trailing behind a farm implement which comprises a manure container supplying liquid manure under pressure to the liquid distributor.
From DE-3703743 C2 is known a rotating liquid distributor with a circular distribution housing with peripherally spaced outlet openings connected to outlet hoses and with a driven rotor which supplies liquid under pressure to the outlet openings in the distributor housing. On account of leakage between the outlet opening of the rotor or the nozzle and the outlet opening, the distributor housing may be filled with liquid which, while the liquid distributor is in a slant position, may flow out of the other outlet openings, thereby causing an uneven liquid supply to the various outlet openings and hoses.
From EP-0079018 is known a rotating liquid distributor with a circular distributor housing where the outlet openings are positioned in the side walls of the housing. A driven rotor with outlet openings
ozzles for liquid under pressure sprays the liquid into the outlet openings, connected to hoses which transport the distributed liquid to a spreader boom mounted at the rear of a farm implement, for instance a trailer with a manure container and a pump for supplying the liquid manure to the liquid distributor. Here too liquid may leak out between the rotor's nozzle opening and the outlet pipes in the distributor housing, thereby filling the distributor housing so that liquid may flow out uncontrolled through the outlet openings which at that moment are not covered by the nozzle openings of the rotor. This may also cause an uneven flow of liquid through the outlet openings and the hoses when the liquid distributor is in a slant position.
The purpose of the present invention is to produce a rotating liquid distributor where said drawbacks with uneven liquid distribution to the outlet openings and the thereto connected hoses/pipes are removed, as well as to produce a rotating liquid distributor with a simpler construction of the distributor housing compared to a distributor housing which is divided into a number of compartments by means of radial partitions as shown in the above-mentioned SE-8505255-3.
The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the claims.
Thus a rotating liquid distributor is obtained where the liquid flow from the peripherally positioned outlet openings with connected hoses, remains as good as even when the liquid distributor is at a slant, which may happen when the liquid distributor is placed on a trailer with a manure container which supplies the liquid distributor with liquid manure under pressure, when said trailer is driven across a sloping terrain; needless to say, the same applies when the vehicle is driven down or up an incline.
The invention will be described in more detail in the fo
