Description

The utility model relates to agricultural engineering, in particular to devices for sowing non-loose and low-flowing grass seeds.

A sowing device is known, including a hopper with a conveying element placed therein, made in the form of a cylindrical spring mounted for rotation and having a seeding limiter. To increase the uniformity of sowing seeds along the row, the sowing device has the ability to change the angle of inclination, and the working element of the conveying element is made in the form of a cylindrical replaceable spring located at an angle with a step gradually increasing in length, inside of which there is a replaceable tube, additionally stretching the seed layer (patent RU 91797 U1, 03/10/2010).

This device is the closest analogue to the claimed object in terms of essential features.

This analogue has several disadvantages:

1. The absence of agitators leads to the formation in the bunker of the arch, which does not allow to sow loose and low-flowing seeds;

2. The inconvenience and complexity of adjusting the rate of seeding through the use of interchangeable springs and tubes;

3. When the device moves on a surface with an uneven terrain, the uniformity of seed sowing may be disturbed, since the angle of inclination of the sowing apparatus will change relative to the horizon.

The problem the utility model aims to solve is to provide the possibility of sowing non-loose and low-flowing grass seeds.

Effect: the possibility of sowing loose and low-flowing seeds with regulation of the seeding rate.

This technical result is achieved by the fact that the sowing device for loose and low-flowing seeds, including a hopper with a conveying element placed in it in the form of a spring, while for the sowing of loose and low-flowing seeds, the hopper, with a shaft vertically mounted in it on the bearings, is made in the upper conical, in the lower part - cylindrical, and the spring located on the shaft is a flexible spiral with a rectangular profile, which allows you to set the seeding rate by changing the pitch of its turns with an adjusting nut, agitators welded to a washer mounted on the shaft between the adjusting nut and lock nut do not allow the formation of an arch.

The essence of the utility model is illustrated by the drawing: Sowing apparatus, side view 1 - hopper; 2 - shaft; 3 - spring; 4 - agitators; 5 - washer mount washer; 6 - an adjusting nut; 7 - a lock-nut; 8 - bearings; 9 - bearing housing; 10 - emphasis.

The sowing apparatus consists of a hopper 1, in which a shaft 2, a spring 3, agitators 4 are placed. The upper part of the hopper has a conical shape, and the lower part is cylindrical. Shaft 2, mounted in bearings 8 vertically in the center of the hopper. Bearings 8 are installed in the housing 9. Two agitators 4 are welded to the washer 5 mounted on the shaft 2 between the adjusting nut 6 and the lock nut 7. The spring 3 passing through the conical and cylindrical parts of the hopper is mounted on the shaft 2 between the adjusting nut 6 and the stop 10 welded to the bottom of the shaft 2. The spring 3 is a flexible spiral rectangular profile. The adjusting nut 6 and the lock nut 7 are connected to the shaft 2 by a thread.

The metering device works as follows:

Shaft 2 is driven from the seeder wheel through a gearbox. When the shaft 2 rotates, the spring 3 and the agitators 4 rotate with it. Rotating, agitators 4 destroy the arch formed by loose and low-flowing seeds. Seeds under the action of gravity and the work of agitators 4 descend down the conical part of the hopper 1, are captured by the coils of the spring 3, move into the cylindrical part of the hopper 1 and move into the seed tube. Setting the seeding rate is carried out by changing the pitch of the turns of the spring 3 by tightening or loosening the adjusting nut 6 on the shaft 2, as well as by changing the speed of the shaft 2 through the gearbox. A washer 5 secures the agitators 4 welded to it on the shaft 2. A lock nut 7 secures the washer 5 and fixes the adjusting nut 6 on the shaft 2. The bearings 8 support the shaft 2. The stop 10 secures the spring 3 in the lower part of the shaft 2.
