DESCRIPTION:
BRIEF SUMMARY
The invention concerns a device for periodic injection of liquid manure in a concentrated jet in a soil, wherein the device is adapted to be supplied with pressurized liquid manure from a pump or container.
Liquid manuere, i.e. a mixture of animal manure, urine and water, is used in agriculture for fertilizing soils.
The simplest method of spreading liquid manure, such as slurry, is to spray it or pour it over the soil. This leads to substantial evaporation of components in the liquid manure, odour problems and often also run-off problems, especially in sloping terrain.
In order to reduce the problems associated with evaporation, odour and run-off, while at the same time increasing the soil's absorption of the nutrients in the liquid manure, it is advantageous to place the liquid manure in grooves which are preferably closed afterwords.
U.S. Pat. No. 4,907,516 discloses a method for periodic depositing of liquid manure in a soil, performed by a device pulled behind a vehicle to which pressurised liquid manure is supplied from a pump, whereby the liquid manure is injected in a concentrated jet under pressure, with the result that the liquid manure forms and fills a groove in the soil.
U.S. Pat. No. 4,624,193 discloses a method and an apparatus for the jet injection of agricultural liquids into the soil, in which a series of jet nozzles, one for each plant row, is spaced along the usual tool bar carried by a tractor. A timing distributor connects high pressure liquid successively to the nozzles to inject a high velocity slug of liquid which will penetrate the soil to an agronomically satisfactory depth.
The object of the invention is to provide an improved device for depositing liquid manure in a soil, where evaporation, run-off and odour problems are avoided, and where the device ensures an even and problem-free injection of the liquid manure in the soil.
The object is achieved according to the invention with a device of the type mentioned in the introduction, characterized by the features which are indicated in claim 1.
The invention will now be explained in more detail in connection with the description of several embodiments, and with reference to the drawing, in which
FIG. 1 illustrates a tractor pulling an injection device according to the invention,
FIG. 2 illustrates the injection device, partially in a longitudinal section made in the tractor's direction of movement, and a groove which is formed by the injection device,
FIG. 3 is a cross section of the groove in FIG. 2, where the section is made across the tractor's direction of movement,
FIG. 4 is a longitudinal section of a preferred embodiment of the injection device according to the invention,
FIGS. 5a, b and c illustrate different designs of a breaker element for use together with the injection device illustrated in FIG. 4,
FIGS. 6a and 6b are front and side views, respectively, illustrating an alternative injection device,
FIGS. 7a and b illustrate designs of alternative breaker elements,
FIG. 8 illustrates a second alternative design of a breaker element.
FIG. 1 illustrates a tractor 2 pulling an injection device 1 according to the invention in a direction of movement indicated by the arrow P.sub.1. The injection device forms part of an agricultural tool which is preferably composed of several injection devices, a tank for liquid manure, one or more pumps for pressurizing the liquid manure, pipes or hoses for the supply of liquid manure to the injection devices and the necessary supporting and securing elements. With the exception of the injection device all of these elements are known, and will not be described in more detail.
FIG. 2 illustrates the injection device in closer detail. A pressure chamber 3 is supplied with liquid manure through a supply pipe 4. The pressure chamber is arranged on top of a shoe 7 which is dragged along a soil 80 by the tractor.
A nozzle 5 provided in an opening in the shoe 7 generates a concentrated jet 9 of liquid manure directed towards the soil 80. The jet is interrupted periodically, thus forming a disconti
