1,189,542. Fertilizer distributers. STAMICARBON N.V. 5 July, 1968 [7 July, 1967; 17 June, 1968], No. 32342/68. Heading A1D. Fertilizer solutions or fertilizer suspensions, insecticides or herbicides in liquid form are pumped from a tank to a supply pipe 28 where it is discharged on to a target plate 27 which distributes the liquid evenly around a catching vessel 26. This vessel comprises a plurality of sectors 35 with corresponding grooves 32 and discharge passages 30. The liquid passes from the discharge passages to hoses (31), Fig. 4 (not shown) and thence to drip pipes 22 for distribution. The upper face of the target plate can be convex or concave and the side of the catching vessel can have a sliding splash shield 33 which supports the supply pipe via a clamp 34. In a modification the target plate is supported on a rod which extends up into and is connected to the supply pipe 28, Fig. 7 (not shown). In a further modification the liquid is supplied to a vortex chamber (5), Fig. 1 (not shown), which has an outlet pipe extending into the chamber such that as the liquid rises in the chamber it spills evenly into the outlet and thence to the catching vessel. |
