FLOW MATERIAL DISTRIBUTION SYSTEM

The invention relates to a spreading arrangement of filing material, such as slurry, carried through a pipeline, preferably including a reservoir located in a movable carriage, a pumping unit for pumping the material into the piping, and the necessary piping said dispensing arrangement comprising at least a first manifold and then downstream two at least two second manifolds to which said tubular members are ejected to expel material and that at least the second manifolds are provided with movable closure means operable to close and open the manifold from the manifold. parts of the outgoing flow paths.

15 Slurry trolleys are known in the art for applying pumping and piping material to fields. The device of such a known solution is a cylindrical housing part located downstream of the pump, within which is provided a rotor with a cutting blade rotated by a fluid motor. From the outer surface of the dispenser all the hoses, for example 40-70 pieces, are separated into which the material is distributed. The hoses are routed to a spreader rack arrangement 10-15 meters wide behind the Vau-20 nu. The arrangement thus has hoses of various lengths, the shortest in length, e.g. 1 m and the longest more than 8 m.

, ·. The disadvantage of such an arrangement is that the apparatus requires a large number of hoses which still have large length differences between them and consequently large differences in flow resistance. Over time, pi -.;. The 25 shortest hoses tend to accumulate more dirt on the wall than the shortest hoses.

, ·· \ Due to the lower flow resistance of the short hoses, these hoses maintain a higher flow rate. Higher flow will keep the walls clean. In addition, the known solution requires a considerable number of hose meters when all hoses start from the same point.

DE-A-196094 discloses a filing material dispensing arrangement having a first manifold, by means of which the flow is divided into a plurality of tubes, each of which leads to flow to the second manifolds from which the flow is discharged. The solution uses conventional shut-off valves to shut off the flows in the various sections of the pipeline.

2 114277 DE discloses a solution for providing flow openings from a manifold with movable closing means. The closing members are flaps that are pivotable in the flow opening or the like.

In this solution, the passage of dirty material, such as slurry, through the open orifice 5 or the closing of the flap in the orifice upon closure are critical steps for functionality. When the opening is open, the shut-off valve is in place and material can accumulate at critical points in the opening. In this case even closing the flap may become impossible if desired. The openings and flaps are passive members and do not maintain the flow opening function.

The movable closing members of the invention are capable of keeping the outgoing flow port actively cleaned at all times as the material is led through manifolds.

The fluid distribution arrangement according to the invention is characterized in that the movable closure means are rings that are movable in the direction of the manifold, the edge of which is sharp in the part which passes through the outgoing flow opening in the wall of the pipe.

Other preferred embodiments of the invention are set forth in the following dependent claims. , claims.

An advantage of the dispensing arrangement according to the invention is that the material supplying pipes are all of the same size and the material supplied to them is thanks to special distributor arrangements. * · · At substantially the same pressure to ensure a uniform application result. The homogeneity of the material is also ensured by one or more successive downstream positioning,;, 25 shut - off valves, which allow fixed or similar access to the piping. even the material is always sized to fit in the pipeline. Moving closure arrangements in the manifolds ensure that no blockages occur and that the outflow pipework remains open.

Figure 1 shows a slurry trolley with a tank 1 with a slurry manure spreading device attached to the rear. The apparatus includes a pump 2 and a transfer tube 3 conducted from the first manifold 4. Three transfer tubes 5a, b, c 5 continue to flow from the manifold 4 to three parallel manifolds 13. There are still auxiliary manifolds 12 in front of the manifolds 13. but the diameter of the tubes 13 can be reduced if used. From the manifolds 13, the actual material distribution hoses 14 continue to flow from which the material flows into the field. The plant may also be followed by a mulching device to mix the slurry into the field.

10

At least the manifolds 13 include, as shown in Figure 3, flow openings for outgoing pipes 14. Each flow opening can be closed and opened by a movable closure member 7,8. The closing members are secured to one another by means of a handle 6 and are moved together by means of a lever 10 and a cylinder 9. The closing members 7,8 are rings 7, which are fitted within the manifold 13, rather precisely, as well as truncated rings 8, which are disposed at the movable flow connections. The closing members are moved back and forth over the outgoing flow openings, whereby their cutting edge allows each flow opening to remain open. Figure 3 illustrates an embodiment in which all the closing members simultaneously cross the flow opening.

The flow from the manifold 13 can be controlled by various movements of the cylinder 9. The movement velocity of the cylinder 9 can be adjusted by adjusting the volume flow of hydraulic fluid to the cylinder *. The stop time of the cylinder at the end of the stroke can be adjusted and the cylinder 9 also has various stroke lengths in one embodiment, and also, for example, the area in which the reciprocating motion 25 takes place.

The closing members 7,8 are secured to the arm 6 by means of transverse support blocks 11. The support pieces ... and the closing members move the mass in the manifold 13 somewhat, and this is only an advantage when aiming for an equal flow for each outgoing flow opening.

30

When dispensing through all three manifolds 13 is not desired, one or more manifolds may be closed by stopping the closure members 7,8 at the outgoing flow openings. The stopping can take place, for example, by stopping the cylinder 9 at the corresponding position. In one embodiment, the closure members 7,8 are located in the manifold 13 so that at different times they pass through the flow openings. In this case, the manifold cannot be disconnected from the spreading operation by means of closing means. The advantage, however, is a slightly more uniform flow in the piping 5 through which the material is led to the manifold 13.

Figure 2 shows a possible closure member arrangement to be fitted inside the manifold 4. The arrangement is otherwise the same as in the manifold 13, but the closing members 7,8 are now fixed to the arm 6 so that they pass through the outgoing flow openings at different times. Thus, in the solution, the flow of material from the incoming pipe 3 is continuous, since at least one outgoing opening 10 is always open. The solution also provides the advantage that, if necessary, one of the outflow openings can be closed by stopping the entire movement arrangement so that the closure member remains at the desired opening to close it. In the solution of Figure 2, the other two flow openings will then remain open.

15 The control of the actuators made by the cylinders 9 or the like in linear motion can be traced so that their movement speed is adjustable. Further, they can be stopped at desired positions and that the length of their reciprocating motion can be adjusted and arranged to travel within a range of motion of the actuator. Not all of these features are available. however, it may be necessary in the basic form of the apparatus, but the manifold already operates by the fact that the closing members extend beyond the outgoing flow openings.
