Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase the uniform distribution of fertilizers. The material from the process tank (bunker) 3 through the discharge window 5 is fed by the feeder by means of a tuck guide 8 to the working bodies of the fire rotors 9. Part of the fertilizers trapped by the blades of the fire rotors 9 falls on the casing 6 of a trough-shaped cross section with a solid upper surface and partially open bottom, then into material receivers 13 and onto centrifugal spreading discs 14. For uniform application of fertilizers through the open lower part of the transporting device and adjusting the density and the directional flow of particles in the upper part of the casing of the transporting device, the reflectors 16, adjustable in height and angle of inclination of the flap, are installed. Another part of the material, hitting the blades of the sticking rotors, is immediately scattered over the floor surface.

Description

The invention relates to agricultural machinery, in particular to devices for the surface application of mineral fertilizers and other bulk materials, including during the growing season of plants in the cultivation of agricultural crops according to intensive technology using tramlines, and can be used for spreading sand, salt , crushed blast waste and other materials.

The aim of the invention is to increase the uniformity of the distribution of material over the surface.

FIG. 1 shows a diagram of a fertilizer machine, rear view; in fig. 2 - part of the transporting device, section.

The fertilizer machine has a frame 1 with support wheels 2. On the frame 1 there is a process tank 3 (bunker) for accommodating bulk material. Technological tank 3 is equipped with a material feed mechanism 4 to the unloading window 5, overlapped by a metering valve. The material feed mechanism 4 is driven from the tractor's power shaft or from the support wheel (the drive to the material feed mechanism is not shown in the drawing). For handicap

The material flows are mounted on the transport device casing 6 in the discharge chute 7 and the tube-8s are installed. The material-flow through the tube-guides 8 is fed to the working bodies of the rotor 9 rotating at opposite directions. To the frame 1 of the machine by means of vertical hinges 10 are fixed height-adjustable support bars 11, located in the working position across the direction of movement of the unit. On each carrier bar 11 a centrifugal spreading device 12 is installed, which has a material receiver 13 and centrifugal spreading disks 14 with a device for driving them. The drive 15 centrifugal spreading discs can be carried out using a hydraulic motor (or through mechanical transmission). The hinge rotor 9 is connected to the material receiver 13 by a transporting device in the form of a trough-shaped casing with a continuous upper surface and a partially open lower one. The upper surface is made according to the shape of the averaged trajectory of the free web of fertilizer particles. For uniform application of fertilizers through the open part of the casing and to adjust the density of the directional flow of particles to the spreading discs, the reflectors 16 are adjustable on the upper surface of the casing and are adjustable in height and angle of inclination of the valve.

The centrifugal spreading devices 12 on the supporting bars x 11 are installed by means of the guides 17c, which can be moved along the supporting bars 11.

The position of the centrifugal spreading devices 12 on the supporting bars x 11 is fixed by locking devices 18. The casing 6 of the transporting device is attached to the frame 1 of the machine for applying fertilizer to the hinge connection 10. The centrifugal spreading disks 14 are driven by hydraulic motors 19 and by means of V-belt transmission from one disk to other.

The drive of the horn rotors 9 is produced from the tractor's PTO through transmission shafts, reverse gear and overrunning clutches.

The material from the process tank 3 by the feed mechanism 4 through the discharge window 5, overlapped by the metering valve, is guided with the aid of a tuck guide to the outer and inner blades of the firing rotors 9, rotating in opposite directions with a frequency of 810 rpm. The casting rotors 9 make a directional throw of the material from the bottom up, along the way, by grinding the blades, the material, especially the wetted one. Part of the material captured by the rotor blades enters the casings of the transporting device connecting the pivot rotors 9 with the material receivers 13. Fertilizers from the Material receiver 13 enter the centrifugal spreading disks 14 and spread evenly over the floor surface.

Another part of the material, hitting the working bodies of the fire rotors 9, is immediately scattered over the floor surface.

The initial setting of the fertilizer applicator on the uniform distribution of the material over the surface of the field is accomplished by bringing together or removing the centrifugal spreading devices 12 along the support bars 11. At the same time, the locking device 18 is released.

When transporting fertilizer machines, the carrier bars 11 and the covers of the transport device 6 rotate around the hinge 10 and are installed in a vertical position.
