Abstract

The invention relates to agriculture, in particular to the sowing of agricultural crops. The purpose of the invention is to improve the quality of sowing. The device includes a material spreader with a capacity of 4 for bulk materials and a spreading machine 5. An elastic film 2 and a marker 7 are attached to farm B., which is installed on the side of the spreader. Equalizer 8 of the furrow crests is installed in front of the chassis spreader. When the device moves across the furrows, the spreading machine 5 feeds the seeds onto the elastic film 2. Moving from film 2 copies the shape of the furrows. The seeds, rolling into the recess of the film along its smooth surface, remain in it until they come off the film. Thus, the seeds fall into the furrows. 2 sec. f-ly, 2 ill. S

The invention relates to agriculture, in particular to the sowing of agricultural crops.

The purpose of the invention is to improve the quality of seeding.

FIG. shows the grooves, transverse section; in fig. 2 - device for sowing agricultural crops, top view.

Grooves 1 are preliminarily cut on the soil surface, across which elastic film 2 is moved, into which seeds 3 are dispersed in a spreading manner (Fig. 1).

A device for carrying out the method consists of a spreader with a capacity of 4 for bulk materials (seeds, fertilizers), a spreading device 5, ferm 6, on which the marker 7 and elastic film 2 are fastened. Equalizer 8 is installed in front of the chassis of the spreader.

When moving the device across the furrows

The spreading machine 5 feeds the seeds 3 onto the elastic film 2 attached to the truss 6. Moving with the elastic film

2 copies the shape of the grooves 1. The seeds 3, rolling down into the recess of the film 2 along its smooth surface, remain at the bottom of the furrow all the time until they leave the film. So the seeds

3 fall into grooves I.

In order not to violate the shape of the furrows 1 by the chassis of the spreader, it moves along the sown strip. Therefore, the marker and set in the seeding strip n.

The soil leveler 8, installed in front of the spreader's running gear, aligns the ridges of the furrows 1 and provides for the device to move on a flat surface. With the equalizer 9, the seeds 3 are closed in the furrows 1.

The speed of movement of the film is chosen depending on the distance between the grooves, the size of the seeds, and the depth of the furrows (depth of seed placement). With large values of these parameters (distance, seed size, furrow depth), the speed of the film movement increases.

When granulated fertilizers are applied by the belt method, furrows are arranged on the soil surface over snow. When this fertilizer granules pre-mulch. Snow under such granules of fertilizer melts faster. This protects them from demolition. by wind and sea water. The proposed method has the greatest effect on heavy, periodically waterlogged soils.

Claims (2)

1. A method of sowing agricultural crops, including cutting of sowing furrows with seed feeding and subsequent soil incorporation, characterized in that, in order to improve the quality of sowing, a smooth elastic film is moved across the cut furrows to ensure their copying its surface, and their embedding is carried out after the latter has been removed from the moving film in the bed of the furrow. 2. A device for sowing agricultural crops, containing a frame with a soil leveler and a spreader of materials with a tank, a scattering device and a running gear fixed on it, characterized in that the device is equipped with a farm installed on its side with a smooth elastic one fixed on it film and marker, and the equalizer is installed in front of the chassis spreader. 0 five 0
