Abstract

A self-propelled pneumatic mini-seeder, consisting of a frame with two driving wheels, a drive of driving wheels, an energy tool - an internal combustion engine, a seed hopper, in the lower part of which a metering device is installed, characterized in that it is equipped with a pneumatic conveying system including a blower fan, an ejector device, a distribution head and pneumatic seed tubes, while the coulter section is mounted to the seeder frame by means of a parallelogram linkage mechanism with two a row in a checkerboard pattern with openers, two support wheels and zagortachami.

Description

The proposed utility model relates to agricultural engineering, in particular to devices for sowing grass seeds in limited areas - lawns, football fields, summer cottages, farms and breeding plots.

Known seeder for sowing small-seeded crops CP-4 [1], which consists of the following main assembly units: self-propelled energy means, consisting of a frame with two drive wheels, drive wheels and energy means (internal combustion engine), sowing sections, chain drives and timber.

The seeder bar is intended for installation on it of working bodies and sowing sections of the seeder. To connect the seeder to a self-propelled power tool, there are studs with which you can adjust the height of the seeder relative to the last.

The sowing section consists of a supporting frame, which is two parallel strips, on which are fixed: in front of the bracket, rear roller loading mechanism, section limiters. In the middle part there is a sowing device, a coulter, and in the back part a zagotachik, a packer roller, a scraper.

The sowing device is a housing (hopper) on which a brush sowing drum is mounted, which rotates in two bearings of sliding bearings, sprockets, rotary sowing disk with holes of different sizes, watering cans.

The sowing apparatus receives a drive from the press wheels, by means of chain gears, when the seeder moves, the rotating brush sowing drum grabs the seeds and directs them into the seed tube through the hole in the hopper and into the sowing disk, then the seeds are placed in the furrow formed by the opener, after which the furrow is closed with a zipper and sealed with a packer roller.

A disadvantage of the known device is its sectional design (seed capacity for each apparatus, individual adjustment, etc.), which increases their metal consumption, time spent on maintenance when changing seeding rates, sowing patterns, seed fractions, while small individual seed containers they require frequent refueling of seeders, as a result of which labor productivity and the efficiency of their use in sowing are reduced.

The technical result of the achievement, which is directed by the claimed utility model, is to increase labor productivity and efficiency of the proposed seeder when sowing grass in limited areas.

The technical result is achieved by the fact that the proposed self-propelled pneumatic mini-seeder is equipped with a central seed hopper, in the lower part of which a metering device is installed, and a pneumatic conveying system, including a blower fan, an ejector device, a distribution head and pneumatic seed tubes.

The presence of centralized dosing with pneumatic transportation of seeds to the coulters significantly reduces the time for refueling and maintenance of the unit, which leads to an increase in labor productivity and the efficiency of using this self-propelled pneumatic mini seeder for sowing.

The proposed utility model is illustrated in the drawing.

Self-propelled pneumatic mini-seeder consists of a frame 1 with two driving wheels 2, a drive of driving wheels 3, an energy tool (internal combustion engine) 4, a seed hopper 5, in the lower part of which there is a metering device 6, a pneumatic conveying system 7, which includes: fan 8, ejector device 9, distribution head 10 and pneumatic seed conduit 11.

In the particular case of a self-propelled pneumatic mini-seeder, a pressurizing fan operating from a direct current generator 12, which is rotated through an actuator 13 from an energy tool (internal combustion engine) 4 of a mini-seeder, can be used as a blower fan 8.

To the frame 1 of the mini-seeder, by means of a parallelogram linkage mechanism 14, the coulter section 15 is fixed, with coulters 16 mounted in two rows in a checkerboard pattern, two support wheels 17 and zagortachi 18.

The technological process of operation of the mini-seeder is as follows: an energy tool (internal combustion engine) 4 through the drive 3 drives the drive wheels 2, the blower fan 8 provides air supply to the pneumatic conveying system 7 of the mini-seeder. Seeds from the hopper 5 come from the sowing apparatus 6 to the ejector device 9, where they are carried by the air flow into the distribution head 10, which ensures the distribution of the seed flow through pneumatic seed tubes 11 and further into the coulters 16 of the coulter section 15.

The metering device 6 is driven from the drive wheels 2 by means of a chain drive and provides a seeding rate of 5 to 80 kg with a working width of 100 cm with a row spacing of 5 cm.

The use of the proposed compact, lightweight and economical self-propelled pneumatic mini-seeder will increase labor productivity and efficiency of its use. The presence of a pneumatic conveying system allows both ordinary sowing of breeding plots and sowing of lawns by the surface-spread method.
