Description

The invention relates to agricultural machinery, in particular to machines for distributing mineral fertilizers and bulk materials.

A known machine for distributing bulk materials. The disadvantage of this machine is the inability to ensure uniform distribution of bulk materials when working on slopes.

The purpose of the invention is to improve process reliability.

The goal is achieved by the use of two grooved distribution devices.

In FIG. 1 shows a general view of the machine; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section BB in FIG. 2; in FIG. 4 - diagram of the hydraulic drive of the working bodies.

The machine comprises (Fig. 1) a frame 1 with support wheels 2. A body 3 is mounted on the frame D, to which two distributing devices 4 with a drive 5 are mounted.

The bottom 6 (Fig. 2) of the body 3 is made in the form of a gable divider having a cross section in the form of a triangle. Between the inner

The surface of the body 3 and the bottom 6 parallel to the longitudinal axis of symmetry of the machine have longitudinal discharge windows equal to the diameter of the distribution devices 4. Above these windows are mounted metering choppers 7 with a drive 8.

The distribution device 4 is made in the form of two horizontal symmetrical sector covers 9 with windows in the upper part and open from the sides. Sector covers 9 are installed open from the top of the windows opposite the discharge windows of the body 3.

At the bottom of the casing 9 (Fig. 3), concentric ribs 10 are installed, forming grooves of the same width. A vertical shaft 11 with horizontal rods 12 is installed in the center of the sector casing 9. To each rod 12, vanes 13 are fixed perpendicular to the horizon, the number of which is equal to the number of grooves. The blades 13 are located opposite the grooves and rotated relative to the rod 12 by an angle increasing from the shaft 11 to the end of the rod 12.

Yes, the blade 13 on the rod 12 in width covers the cross section of the gutter and has different dimensions in width.

The scheme of the hydraulic drive of the working bodies (Fig. 4) includes an oil tank 14, an oil pump 15, a distributor 16, flow regulators 17, two hydraulic motors 5 of the drive of the distribution device, a hydraulic motor of the chopper-dispenser 8, the shafts of which are connected by a chain gear whose filter 18, cooler 19, safety valve 20.

The machine operates as follows.

Switching devices 4 and metering choppers 8 are turned on. Fertilizers in the same amount through the discharge windows enter the bottom of the grooves of the housings 9. Rotating with the shaft of the rod 12 blades 13 pick up the mass and move it along the grooves. Fertilizer particles under the action of centrifugal forces and due to the angular velocity of the blades 13 tend to the outer wall of the gutters. But their movement is prevented by the blades 13, respectively installed at different angles, so there is a discharge; particles of material occurs without sieving along the width of the grip and in the direction parallel to the movement of the machine, due to which a high uniformity of distribution is achieved. Each rod operates in the area of two sector housings 9, so material is ejected in opposite directions.

The dose of material is controlled by changing the frequency of rotation

dispensers 7 using the flow regulator 17 and the speed of the unit, and can also, within certain limits (so as not to affect the uniform distribution along the passage length), by changing the speed of the shafts 11 using the flow regulator 17 and the number of shovels on the blades shaft.

Claims (2)

1. A machine for the distribution of bulk materials containing a hopper with a gable bottom, discharge windows and chopper-dosers mounted on a frame with wheels, characterized in that, in order to increase the reliability of the process, it is equipped with two distributors adjacent to the discharge windows devices, each of which is made in the form of two horizontal symmetric sector covers with windows in the upper part and open on the sides, and concentric ribs with images are installed on the bottom of the casing gutters, while in the center of the sector casings there is a vertical shaft with a horizontal bar with blades mounted with the possibility of moving it in the plane of the casing,  2. The machine according to claim 1, characterized in that the blades are installed in the gutter area in a vertical plane and at an angle to the rod, while the angle of installation of the blades increases the blade to the end of the rod., 790844 Jla fig.Z
