RU2379874C1 - Disk boot with drum distributor - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: facility consists of immobile hollow axle and of drum-seed-distributor rotating on axle. The drum-seed-distributor is secured on the disk boot and is divided with blades into central and smaller periphery chambers. The periphery chambers are formed with blades in form of curvilinear surface, for example a quarter of segment of paraboloid of revolution. The blades are arranged with their bigger sides to external diametre of the drum-seed-distributor with alternate fixation to external and internal sides of the drum.

EFFECT: facilitating rational utilisation of day surface of field and zone of plant nutrition due to alternating zones of seed distribution along width of sown band.

Description

The invention relates to agricultural machinery, in particular to the openers of seeders for sowing crops.

A well-known device that can perform seed placement in the soil is the design of a double-disc coulter (N.I. Klenin, V.A. Sakun. Agricultural and reclamation machines. M: Kolos, 1994, p. 222). The coulter consists of a housing; two disks, pointed along the outer circles and located to each other at an acute angle; two rolling bearings; a reflective plate, it is also a scraper; branch pipe for seeds; leash and pressure spring.

This coulter is prone to clogging with crop and plant residues, which reduces the reliability of their work, worsens the quality of sowing, and therefore leads to lower yields.

Known combined coulter for planting seeds and fertilizers in the soil (RU No. 2249936, IPC АСС 7/20, 04/20/2005), which includes a housing with a mount for attachment to the lead of the opener of the seeder, a flat disc mounted at an angle to the direction of movement, and Seventh Guide.

The design disadvantages are the small width of the sown strip and the unstable uniformity of the distribution of seeds over the feeding area.

Closest to the technical nature of the claimed device is a seeder according to patent RU No. 2269884, IPC АСС 7/18, 02/20/2006 "Universal seeder", containing a rotating drum-seed distributor on a fixed hollow axis, separated by blades, fixed to the sides of the drum-seed distributor, to the central and small peripheral cameras.

The above device has the following disadvantages: limited sowing in moist soil; Dependence of seed placement depth on soil condition.

The proposed device allows to obtain a new technical effect, to alternate the zone of distribution of seeds across the width of the sowing.

This effect is achieved by the fact that the drum-seed distributor is mounted on the disk coulter, and the peripheral chambers are formed by the blades in the form of a curved surface, for example, a quarter of a paraboloid segment of rotation mounted with the greater side to the outer diameter of the drum-seed distributor, with alternating fastening to the outer and inner sidewalls.

The invention is illustrated in the drawing, which shows the device, General view, isometry.

The proposed device consists of a disk opener 1 mounted rotatably on a hollow curved axis 2. On the inner side of the disk opener 1 is fixed a drum-seed distributor 3, consisting of sidewalls 4 and blades 5, which form the central 6 and peripheral 7 chambers. The blades 5 are made in the form of a curved surface, for example, a quarter of a segment of rotation paraboloid, are mounted with the larger side to the outer diameter of the drum-seed distributor 3 with alternating fastening to the outer and inner sidewalls 4.

Single disc opener works as follows.

When moving the disc coulter 1, rotating on a hollow curved axis 2, shifts the topsoil and opens the groove. Seeds along the internal volume of the hollow bent axis 2 fall into the central chamber 6 and peripheral chambers 7 of the seed-reel 3 and fall on the curved surface of the blade 5. Rolling along the curved surface of the blade 5, the seeds are distributed along different paths and acquire different speeds, which ensures their uniform furrow distribution. Due to the attachment of the blades 5 to the outer and inner sides of the drum-seed distributor, the zones of distribution of seeds are alternated to and from the opener disk.

Alternating staggered zones of seed distribution in the longitudinal direction allows more rational use of the daily surface of the field and the plant nutrition zone.

Claims (1)

A device for sowing seeds, containing a fixed hollow axis and a drum-seed distributor rotating thereon, divided by blades into central and small peripheral chambers, characterized in that the seed-drum is mounted on a disk coulter, and the peripheral chambers are formed by blades in the form of a curved surface, for example, a quarter segment of the paraboloid of rotation, installed by the greater side to the outer diameter of the drum-seed distributor, with alternating fastening to the outer and inner sides of the drum.
