DE2848057A1 - Seed slurry orifice jet for seed drills - has outlet orifice and water jet points directly at seed depositing point - Google Patents

Abstract

The seed slurry orifice is used for agricultural and horticultural individual seed drills. The outlet of the curved or straight orifice and thus the water stream, points, or is directed, precisely at the point at which the deposited seed is covered with soil or pushed into the soil but a rolling or washing of the seed is no longer possible. The orifice can be fitted after the pressure roller but in front of the spreader. Specifically, two pressure rollers are built into each single grain seed drill.

Description

Title: Seed slurry nozzles for agriculture and

Horticulture.

Application creation of seed nozzles for rural areas economic and horticultural precision seeds or. Drills, for slurrying seeds of all Kind, especially sugar beet and fodder beet sans, Iwiais, as well as seeds of vegetables and special crops of all kinds.

The state of the art of precision seeders and seed drills has long been technology in agriculture and horticulture known with criticism and bring in areas or in years with sufficient rainfall after sowing, in the water level too good to very good and safe casserole results.

Small good or satisfactory casserole results, on the other hand, are in Years with prolonged drought after sowing, or regularly in dry areas expected. In such areas one is forced every year to sow, especially carry out the sugar beet as early as possible in order to reduce moisture to make full use of it.

The dangers here are that the seeds are often in the ground for a very long time because this, because of its insufficient warming, does not yet feed the seeds Stimulates germs. During this period, all plant and animal pests have of the sugar seed like millipedes, collembolon, springtails and the like, as well as all possible mushrooms enough time to germinate the relatively unprotected To eat the seed or to infect it. which then consequently leads to bad up leads to insufficient emergence results.

But also mistakes in a too deep soil preparation for sowing and incomplete and insufficient pressing of the seed groove by the pressure roller if the ground is too solid in places, can especially again with one persistent drought after sowing, to unsatisfactory emergence results to lead. Because the seed, or at least part of it, does not get to the interrupted one Capillary activity of the soil, or does not have enough soil clearance and / or fencing and koit does not germinate. But even a germinated seed can be in the From above, gradually dried out soil will die off. The consequence for the farmer is, either break the field and re-eie, or an incomplete inventory and thus accept more or less large yield losses.

Task: The inventor set himself the task of creating a process for the containment of all kinds of seeds with a single-grain sowing or drilling device ground sown and develop a change in the mounting of the pressure roller, in order to keep these previously described risks to a minimum and thus optimal To achieve casserole results.

Solution: It is a so-called seed slurry nozzle, which is built into each body of a single corsa or drill device and over a pressureless system is supplied. This is the exit of the nozzle and thus the Water jet aimed exactly at the place where the deposited seed with soil is covered or

is forced into the earth by the pressure roller.

However, it is allowed to roll or wash the seed in the seed furrow no longer be possible, otherwise it should still be from the water jet reached and ground intensively in the soil. To even with places solid ground, an even more complete and reliable ground closure of the seed to be reached in the seed furrow through the pressure roller according to the invention two pressure rollers that are installed at an angle and the seed furrow of both Press the sides at a very diagonal, provided.

The handlers now lay some loose earth over the closed and sludged seeds and secure for a longer time than developments after today State of the art for a moist seedbed.

For the complete protection of the seed against ground loops of any kind, or for a rapid development of the seedling, this water can be treated with an insecticide, Fungicide, nitrogen or 1hr solution can be added. This type of insecticide application has the advantage over surface spraying that it is absolutely environmentally friendly is, the seed really completely protects against pests of all kinds and the beneficial insects stay spared.

This seed slurry nozzle, as well as the two inclined pressure rollers in a single grain or. Built-in drill device, bring this to a high technical level Stand, create the best conditions for high emergence results in sugar and fodder beet growing, as well as in maize and vegetable growing, especially in dry years.

In addition, they can be produced and without great technical effort can therefore also be used in practice and can subsequently be or a newer drill must be installed.
