RU2380877C1 - Spreader of organic fertilisers - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: spreader includes body arranged on chassis with slatted apron arranged in it, crushing element and two distributing rotors. Body is equipped with guide plate and flow divider. Plate is arranged with the possibility of rotation and is installed over distributing rotors. Rotor comprises disc with three rows of blades arranged on it. Rows of blades are installed coaxially at various distance from disc surface. In each subsequent row length of blades is more than in the previous one. Rows of blades are arranged at various angles to radial direction.

EFFECT: improved working width of grip, reduced energy inputs for process of fertilisers spreading and lower unevenness of fertilisers spreading.

Description

The invention relates to agricultural machinery, in particular to devices for surface application of solid organic fertilizers.

A known organic fertilizer spreader according to the copyright certificate SU 1613018, comprising a body with a feed conveyor located on a frame with running wheels, struts arranged with a tilt back, with the possibility of rotation, in which a chopping drum is fixed, distributing rotors are placed under the conveyor.

The disadvantage of this spreader of organic fertilizers is the design complexity due to the presence of a rotary rack, and the required uniformity of applying organic fertilizers is not provided.

The objective of the invention is to increase the uniformity of distribution of solid organic fertilizers and the performance of the spreader.

The technical result from the use of the invention is to increase the working width, reduce energy costs for the process of distribution of fertilizers, reduce the uneven distribution of fertilizers.

The technical result is achieved by the fact that in the spreader of organic fertilizers, including a body mounted on the chassis with a slatted conveyor located therein, a grinding organ and two distribution rotors, the body is equipped with a guide plate that is rotatable and mounted above the distribution rotors, a flow separator, the rotor contains a disk with three rows of blades mounted on it, the rows of blades are coaxially located at different distances from the surface of the disk, in each subsequent row the length of the blades to more than the previous, blade rows are arranged at different angles to the radial direction.

In the proposed organic fertilizer spreader, it is possible to change the feed location of organic fertilizers to the distributing rotors by installing a guide plate with the possibility of its rotation.

Distributing rotors are made in the form of a disk with three rows of blades fixed on the upper surface, due to which the distribution of organic fertilizers to different working widths occurs.

In Fig.1 shows a spreader of organic fertilizers, a General view; figure 2 is a top view of figure 1.

The spreader of organic fertilizers for applying solid organic fertilizers contains a body 1 mounted on a chassis, a slat conveyor 2 located in the body, a grinding drum 3, a guide plate 4 mounted in the body, rotatable by means of hydraulic cylinders 5, a flow separator 6, two distribution rotors that contain the disk 8 with three rows of blades 7 mounted on it at different angles to the radial direction, the rows of blades are coaxially at different distances from the surface and the disk, in each subsequent row the length of the blades is longer than in the previous one, the rows of blades are located at different angles to the radial direction.

The spreader of organic fertilizers works as follows.

The conveyor 2 moves the fertilizer in the body of the fertilizer towards the flow of fertilizer towards the chopping drum 3. The chopping drum 3 grinds and feeds the fertilizer to the guide plate 4. When in contact with the guide plate 4, organic fertilizers change their direction and fall on the distribution rotors 7 under their own weight. Ground fertilizers fall on the spreading rotor, where part of them is captured by the first row of blades. The first row of blades captures only some of the organic fertilizers, which depends on the capacity of the working body and is distributed over the surface of the field. Another part of the fertilizer falls into the coverage area of the second row of blades, which, due to the longer length of the blades, distributes the fertilizer over a wide working width. The rest of the fertilizer goes to disc 8, i.e. into the zone of action of the third row of blades of even greater length, and is distributed over the final width of the grip. As a result of this, a more uniform distribution of organic fertilizers over the field surface occurs.
