Abstract

The invention relates to agricultural machinery, in particular to machines for distributing material over the soil surface. The purpose of the invention is to provide directional packing of the material in a protective zone without powdering and damage to plants. The device contains transverse belt conveyors 4, the edges of the outgoing ends of which are located at an acute angle with the apex, in the direction of movement of the device h L so that the intersection point of the edge traces is on the axis of a row of plants, and the spreading blade drum 5 is made in the form of a truncated cone facing apex against the direction of movement of the device and enveloped by a guide casing 7 which is concentrically arranged relative to it. The spreading drum 5, the guide casing 7 and the flexible curtain of chains with ontirovany on the pendulum arm 8, the axis of which is aligned with the suspension tensioning drum axis zhnogo average cross conveyor belt, wherein a flexible curtain suspended from the chain arc, connected to a pendulum arm 8 is pivotally and fixation in the horizontal plane. The material is supplied with a layer of predetermined thickness to the transverse belt conveyors 4, which drop material onto the paddle drums 5, covered by the casings 7, where the material is captured by the paddle blades and ejected from two sides under a row of plants. In this case, the flexible chains of chains reduce the speed of the material and form a protective roller from it. 1 Cpfla, 3 Il SL C a 00 Ј Sl VJ

The invention relates to agricultural machinery, in particular to machines for distributing material over the soil surface.

The purpose of the invention is to provide directional packing of the material in a protective zone without powdering and damage to plants.

Fig. 1 shows a device for distributing material over a soil surface, side view; figure 2 is the same, front view; on fig.Z - the relative position of the transverse belt conveyors and scattering blade drums.

The device consists of a tractor trailer 1 containing a tank with a movable bottom in the form of a chain-slat conveyor 2 and a beater-feeder 3. In the front part of the trailer and below the chain-slat conveyor 2, two transverse belt conveyors 4 are installed, the upper branches of which move from the center of the trailer in different directions. Under the transverse conveyors, spreading vanes 5, having the shape of a truncated cone, facing apex against the direction of motion, are fixed on horizontal, parallel to the longitudinal axis of symmetry of the shaft device. The blades 6 are fixed on the surface of the drums 5. Each spreading drum is enclosed by a guide casing 7. The shafts of the scattering drums and the casing guides are fixed on ejector brackets 8 interconnected by adjustable thrust 9. On the mapping brackets 8 are rotatably mounted in the horizontal plane and fixation there is a flexible curtain of chains 10. The edges of the discharge ends of the transverse belt conveyors are arranged in steps, and the lines connecting their steps are located at an acute angle to the odol axis of the transverse conveyors and form an angle between them, the top of which is directed along the direction of movement of the device. The drive of the chain-slat conveyor 2, the transverse conveyors 4 and the spreading reels 5 is driven from the tractor PTO, the towing device.

The device works as follows.

The prepared material is loaded into the container of the device and transported to the place of its installation. Directly when laying material the device is transported

Claims (2)

1. A device for distributing material over the soil surface, containing a tank installed on both sides of the section, each of which is made up of stepped transverse belt conveyors with leading and tension drums, has a spreading tool installed at the exit end of each section. what. In order to provide a better laying of material into a given zone, the spreading working body is made in the form of a truncated cone mounted on a horizontal axis, located across the entire width of the corresponding section and facing a smaller base against the direction of movement of the device and partially covered by a guide casing , while the spreading drum, the guide casing and the flexible curtain of chains are mounted on an erecting bracket, the suspension axis of which is combined with one of the tensioning drums of the conveyors, the chains of the flexible curtain hanging from the arc connected to the pendulum bracket can be rotated and fixed in the horizontal plane, while the horizontal projections of the projections of the steps of each section are located on a line at an acute angle to the longitudinal axis of the section with the formation of an acute angle between the mentioned lines. 2. The device according to claim 1. characterized by the fact that the bottom of the tank is made in the form of a chain-slat conveyor, over the output end of which the beater metering device is installed. / ./ ,, VnVVi // h, -h / i. eight C: JU1-1 i.
