Abstract

FIELD: agriculture.

SUBSTANCE: planting unit can be used for dissemination of seeds or fertilisers on slopes. The device comprises a reel-pin sowing device for dosing and feeding of the seed material into a hollow truncated cone for directing of the seed material to grooves of the dispensing cone and a pipe for feeding airflow to the seed material. The hollow truncated and dispensing cones are pivotally attached on the axis to the body of the sowing device. The pipe is mounted in the upper part of the hollow truncated cone with the ability to feed airflow on the surface of the dispensing cone.

EFFECT: use of the invention enables to increase uniformity of application of seeds and fertilisers and to improve their contact with soil on the slopes.

Description

The invention relates to the field of agricultural mechanization, in particular to devices for spreading seeds or fertilizers on slopes.

Known reel-pin sowing apparatus (Agricultural machines. Voronov Yu.I., Kovalev LN, Ustinov AN, M .: Higher school. S.118), which sow seeds or fertilizers on the surface of slopes not evenly.

A metering device is known including a spool pin metering device for dispensing and feeding the seed to the truncated hollow cone for guiding the seed to the grooves of the spreading cone and a nozzle for supplying air flow to the seed to be sown (Auth. SU 676207 A, 07/30/1979) .

However, this device when working on slopes does not provide sufficient contact of the sown material with the soil.

The purpose of the invention is to increase the uniformity of the application of seeds and fertilizers and improve their contact with the soil on the slopes.

The technical solution to the problem is achieved by pendulum fastening on one axis of the hollow truncated and grooved cones to the body of the sowing apparatus and giving additional acceleration to the sowing material under the influence of air flow.

The figure 1 shows the operation of the sowing device on the plain;

figure 2 - its work on a slope;

figure 3 - spreading the working body.

A truncated hollow cone 3, located under the neck of the housing and making pendulum movements, is pivotally attached to the housing of the bobbin pin metering device 1 (Fig. 1) on the axis 2. A spreading cone 4 with grooves (grooved cone) 5 is suspended from the same axis 2 under the truncated cone to guide the seed 6. The required clearance between the hollow truncated cone and the grooved cone is provided by two brackets 7. A nozzle 8 is provided in the upper part of the hollow cone 3 to supply air flow.

The device operates as follows. Seeds, fertilizers or their mixture 6 from the neck of the sowing device body enter the truncated hollow cone 3 and fall into the grooves 5 of the grooved cone 4. Moving along the grooves under the influence of the air flow entering through the nozzle 8, the sowing material accelerates onto the treated soil, stubble or grass cover. When the sowing device is operating on slopes with a slope of up to 16 °, the sowing uniformity is ensured by the movable pendulum fastening of the hollow truncated and grooved cones. The cone guide grooves and airflow accelerate the movement of seeds or fertilizers along the grooves, providing better contact of the seed to the soil surface. If necessary, it is possible to regulate the air flow supplied to the grooved cone.

Claims (1)

The sowing device, including a reel-pin sowing device for dispensing and feeding the seed to the truncated hollow cone for guiding the seed to the grooves of the spreading cone and a pipe for supplying air flow to the seed, characterized in that the hollow truncated and spreading cones are pivotally mounted to the body of the metering device, while the nozzle is installed in the upper part of the hollow truncated cone with the possibility of supplying air flow to the surface of the spread ayuschego cone.
