Spreader equipment for liquid manure, e.g. a semi-liquid slurry, comprising at least one injection nozzle (1) which is connected with a supply valve (6) for periodical supply of semi-liquid slurry under pressure from a tank (4) for semi-liquid slurry for direct injection of semi-liquid slurry into the soil. The spreader equipment is preferably provided on a vehicle (H) or on wheels for movement on the surface of the ground (E). Injection nozzle (1) is provided to be in resilient contact with the surface of the ground (E) and comprises a valve housing (1a) with an inlet (1a'), and an outwards diverging and downwards facing outlet passage (1i), and a valve member (1c), which is displaceable axially in outlet passage (1i) against a spring means (1f), towards sealing cooperation with the defining surface (1i') of outlet passage (1i). With periodical pressure being exerted by the semi-liquid slurry on valve member (1c) the latter is urged down for a periodical opening of nozzle opening (C') and, thus, annular ejection of the semi-liquid slurry towards the surface of the ground (E) and into the soil. |
