(54) SPREADER OF BULK MATERIALS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to machines for fertilizing the soil.

Spreaders of mineral fertilizers and lime materials consisting of a bunker, its conveyor, doses of a futher valve and a working body distributing this material over the soil surface ij are known.

Also known spreader bulk materialorop, including the body with the feeding device, mounted on a frame with a chassis, scattering discs and feed augers 121.

The disadvantage of the 1 1And these devices is that their working bodies are located behind the bodywork. :) VA. When the conveyors are working, the bulk material is first picked up in front of the body, causing the center of gravity of the spreader to move backward, which leads to a decrease in the tractor driving wheel L031FO.MKI through the {) hydraulic bracket, and an increase in the unit's drag and energy consumption.

The purpose of the invention is to reduce power consumption for rolling by maintaining an even distribution of material in the body during its spreading.

The goal is to achieve that the feeding device is made in the form of two TpaHcnop-iapoB longitudinally located in the bottom of the body, which are mounted for movement in opposite directions, while the feeding screws with centrifugal disks are located in the front part of the body at the exit of one of the feeding conveyors, and A centrifugal disk is fitted on the back of the body.

FIG. I shows a top view spreader; in fig. 2 is the same, view L in FIG. I; in fig. 3 - the same, saw B in FIG. I. The spreader consists of body I and feed conveyors 2 and 3, left 4 (along the way) and right 5 feed screws, with centrifugal disks 6 and 7 of the centrifugal disk 8 installed behind the body, and mechanism 9 for driving the working parts. The body I of the spreader is mounted on the frame, which consists of two longitudinal spars and the drawbar Yus connecting joint II. The tailgate of the body against the feed conveyor 3 has a metering window 12 and a flap 13. Between the feed conveyor 3 and the centrifugal disk 8 a directional tray 14 is placed. The front bead of the body has a metering port 15 above the feed conveyor 2 and the flap 1.6. Below the conveyor 2 there is a guide tray 17 with a divider 18, left 4 and right 5 pitugs augers with centrifugal disks 6 and 7 and a drive mechanism 19. The drive mechanism of centrifugal disks 6 and 7, including chain and gear transmission 2O. One of the sprockets is rigidly seated on the output end of the shaft of the feeding augers, and the second on the shaft of the centrifugal disk. The turns of the feeds 4 and 5 have left and right winding. The device works in the following way. Before scattering bulk materials loaded into the body with flaps 13 and 16, the required seed rate is established. By switching on the tractor's power take-off shaft, the drive mechanism of the working rider bodies is set in motion. Feed conveyors 2 and 3, moving relative to each other in opposite directions, dispense material through dose windows 12 and 15 in the rear and front sides of the body. The material particles coming from the conveyor 3 through the window 12 along the guide tray 14 are fed to a predetermined point of the centrifugal disk 8, through which they are evenly distributed on the soil surface. The particles of the bulk material coming from the conveyor 2, through the metering window 15, are sent along the tray 17 to the divider 18, where the separation is :; in two streams and feeding augers and 4 and 5 are transported to the centrifugal disks 6 and 7, and the latter, rotating, raz-. throw particles of material over the surface of the soil. Moving from the conveyor belt in opposite directions ensures an even distribution of the bulk material along the length of the body as long as the breaker, which allows reducing the energy consumption for its rolling. The formula of the invention Bulk material spreader, comprising a body with a feeding device, mounted on a frame with a chassis, scattering discs and feeding wrenches, characterized in that, in order to reduce energy costs. made in the form of two longitudinally arranged in the bottom of the body of the conveyors, which are installed with the possibility of peremetseny in opposite directions, while the feed wires ki centrifugal dzhzkami arranged at the front end of one of the output conveyors podakltsih and another outlet in the rear centrifugal disk is mounted.

Claims (1)

Claim A spreader of bulk materials, comprising a body with a feeding device, mounted on a frame with a chassis, spreading discs and feeding screws, characterized in that, in order to reduce energy consumption for rolling by maintaining a uniform distribution of material in the body during its spreading, the feeding device is made in in the form of 30 two conveyors longitudinally located in the bottom of the body, which are installed with the possibility of movement in opposite directions, while feeding augers with centrifugal 35 d claims are located in front of the body at the outlet of one of the conveying conveyors, and at the exit of the other, a centrifugal disk is installed in the rear of the body. ha in opposite directions, dispense material through the metering windows 12 and 15 in the rear and front sides of the body. Particles of material coming from the conveyor 3 through the window 12 along the guide tray 14 are fed to a predetermined point of the centrifugal disk 8, with which they are evenly distributed on the soil surface.
