Description

The invention relates to agricultural machinery, in particular to machines for applying mineral fertilizers,

The purpose of the invention is to improve the uniformity of fertilizer application.

FIG. 1 shows the fertilizer spreader, general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2

The mineral fertilizer spreader contains frame 1, bunker 2, conveyor 3 with slats 4, which rest on the floor of bunker 2 and support table 5. At the back of the bunker 2 a metering valve 6 is installed, and under the leading sprockets 7 of the conveyor 3 - tuft guide 8 and spreading Organ 9. Above the back of the support table 5 there is installed a vibrator 10 with a roller 11, which interacts with a curvilinear protrusion 12 on the rear part of the table 5. The protrusion 12 is made as part of a circle with a radius equal to the radius of the depressions of the drive sprocket 7 tran Vibrator 10 is mounted on axis 13 to the bunker and pressed against the table by spring 14. The rear cantilever end of the support table 5 is supported by spring 15 on the shaft 16 of the leading conveyor sprockets and bent down at an angle of about 10 °. The diameter of the roller 11 is greater than the diameter of the strap 4.

the metering valve 6 on the support table 5. When the vibrator 10 is turned on, the roller 11 through the protrusion 12 interacts with the spring-loaded rear part of the support table 5, driving it together with the fertilizers on it in an oscillatory motion. The vibrator roller 11 jumps over the slats 4 of the conveyor 3, since the diameter of the roller is larger than the diameter of the conveyor slat. Due to the vibration, the adhesion forces between the fertilizer particles weaken, the layer thickness decreases and the fertilizer in the form of small particles is fed to the toner guide 8 and spreading the working element 9. Slats 4. The entrance to the interdental sprocket 7 is raised above the support table 5, not preventing the fertilizer particles from coming off.

Claims (2)

1. Mineral spreaders, holding silo with slatted conveyor and support table, characterized in that, in order to increase fertilizer application uniformity, the supporting table has a cantilever rear part, spring-loaded from below with respect to the shaft of the drive sprocket of the conveyor, and from above it is equipped with a curvilinear projection and contacting him roller with a vibrator. 2. The spreader according to claim 1, which includes the fact that the protrusion on the console part of the table is made as part of a circle with a radius equal to the radius of the cavities of the drive sprocket and the roller diameter is larger than the diameter of the bar.
