Abstract

The invention relates to agricultural machinery, in particular, to devices for applying to the soil solid and semi-liquid organic, mineral and lime fertilizers. The aim of the invention is to improve the uniformity of fertilizer application, increase productivity and reduce energy intensity. The fertilizer spreader contains a wheeled chassis 1 on which the body 2 is installed, a chain-slat conveyor 3 is installed inside the body at its bottom, at the output of which a chopping device 4 is installed. At 2 re 3 the output of the chain-slat conveyor 3 is below the slave branch plane , made in the form of a series of installed rotors 7 and 8. Under the bottom of the body 2, a gearbox with two parallel output shafts is installed, having an opposite direction of rotation for driving the rotors 7 and 8. Roto The bores are installed in the casing 10. The bottom of the casing is made in the form of two arcuate guide flaps 11, in which a longitudinal slit is cut, which is closed by an adjusting flap. On the blades of the rotors 7, 8 there are projections 14, which are inserted into the slot. The power cylinder lifts the tailgate 5, while the fertilizers in the body are fed by a chain-slat conveyor 3 to the chopping device 4. After the fertilizer is crushed, the guiding flaps 15 and 16 are fed into the casing 10, the blades of the rotors 7 and 8 are captured and thrown out flaps 11.

The invention relates to agricultural machinery, in particular, to devices for the introduction into the soil of solid and semi-liquid organic, mineral and

lime fertilizer.

The aim of the invention is to improve the uniformity of fertilizer application, increase productivity and reduce energy intensity.

FIG. 1 shows a fertilizer spreader, rear view; in fig. 2 - the same, side view; in fig. 3 - rotor case with one adjusting flap, top view.

The fertilizer spreader contains a wheeled chassis 1, on which the body 2 is installed, inside the body at its bottom, and a chain-slat conveyor 3 is installed, the output of which has a grinding device 4, made in the form of an auger tool, before the grinding device is a folding rear side 5, driven by power cylinder 6. The exit device of the chain-slat conveyor 3 is installed below the plane of the driven branch by a distribution device made in the form of a number of installed rotors 7, 8. Under the days The gearbox 2 has a gearbox 9 with two parallel output shafts that have the opposite direction of rotation to drive the rotors 7, 8. The rotors are mounted in the housing 10. The housing bottom is made in the form of two arc-shaped guide flaps II, in which a longitudinal slit 12 is cut, which is overlapped by the adjusting flap 13. On the blades of the rotors 7, 8 there are protrusions 14 which enter the process gap 12. Below the driven chain of the chain-slat conveyor 3, above the rotors, there are two guiding flaps 15, 16.

The spreader works as follows.

Having approached the place of fertilizer application, the tractor driver, using a power cylinder 6, lifts the rear flap 5, turns on the drive of the working bodies of the spreader and, moving across the field, spreads the fertilizers. At the same time being in

the fertilizer body with the help of a chain-slat conveyor 3 is fed to the grinding device 4. After ground by means of guide plates 15, 16

fertilizers are fed into the casing 10, where they are captured by the blades of the rotors 7, 8 and, having gained the necessary flight speed, are ejected at a certain angle close to 45 ° to the horizon using arcuate guide flaps 11, and are evenly distributed on both sides of the spreader. At the same time, the protrusions 14 enter into the longitudinal slit 12, proglators pour part of the fertilizer into it and evenly distribute them between

rotors. The fertilizer doses are regulated by the speed of movement of the feed chain-slat conveyor 3, and in the zone between the rotors, depending on the application dose, by increasing or decreasing the width of the longitudinal slit 12 when

using the adjusting valve 13. The width of the adjustment is adjusted depending on the dose of fertilizer by increasing or decreasing the rotations of the rotors 7, 8 with the help of interchangeable sprockets on the gearbox 9.
