Abstract

FIELD: agriculture.

SUBSTANCE: hand operated sowing machine comprises a wind-shielded dispenser with a circular groove, a triangular blade and an element for its fastening on the forearm and the seed spout rigidly connected to the holder. The holder is made in the form of a tube, and the seed spout consists of a flexible hose and a tube. At the outlet of the seed spout a nozzle is mounted with a furrow-making device and two openings in one of which the tube of the seed spout is rigidly fixed, and in the other - the tube of the holder. The opening with the tube of seed spout is closed with the shifted spring-loaded shutter. The opening with the tube of the holder is made passing into a narrow opening for draught connecting the shutter through the transition plate with the slider mounted on the upper end of the tube of the holder.

EFFECT: improved design.

Description

The invention relates to agriculture, namely to the manual sowing of plant seeds.

The closest analogue is patent 2415540 from 10.04. 2011, the disadvantage of which is the bounce of seeds from the sowing point when the seed tube approaches a vertical position and increases the speed of the seeds that leave.

In the proposed seeder, the seeds stop at the shutter, which closes the exit of the vas deferens, when opened with the hand holding the seeder, they freely fall to the sowing point prepared by the furrow divider from a height of 1.5-2 cm without bouncing to the side.

A manual seeder containing a windproof dispenser with an annular triangular trough, a triangular spatula and elements of its attachment to the forearm of the hand holding the seeder by the holder, as well as a seed tube rigidly connected to the holder, characterized in that the holder is made in the form of a rigid tube, and the seed tube consists of a flexible hose and a rigid tube parallel to the holder and a metal plate rigidly connected to it, while in the lower part of the tubes there is a metal nozzle with two holes, and in the lower the tube of the vas deferens is rigidly fixed in the hole, and the tube of the holder in the upper; the hole with the tube of the vas deferens is closed by a retractable spring-loaded shutter, and the hole with the tube of the holder is made into a narrow hole for traction connecting the shutter through a thickening and adapter plate with a slider mounted on the upper end of the tube of the holder, while it is possible to move the shutter with the thumb holding the seeder for the holder resting on the lower end of the slider, after dropping the seeds onto the blind with a triangular blade held by the other hand, while the seeds freely fall from a height of 1.5-2 cm a seed crop prepared by a furrower without bouncing to the side. In this case, the tubes of the vas deferens, holder, connecting plate, nozzle and adapter plate are made of stainless metal, and the slider is made of plastic. The rod is made of stainless string.

Figure 1 shows a General view of the seeder, figure 2 shows the axial section of the seeder without a dispenser.

The seeder consists of two parallel metal stainless tubes of the vas deferens 1 and holder 2, rigidly connected by a metal stainless plate 3, the lower parts of which are rigidly fixed in the holes of the metal stainless nozzle 4.

The opening of the vas deferens 14 is through and closed by a movable shutter 6.

The hole of the holder 15 passes into a narrow hole 18, through which the lower part of the rod 7 is passed, passing through the bulge 17 and secured by a stainless screw 21 on the upper part of the curtain 6.

In the initial state, the curtain is stretched with a rubber loop or spring 16, mounted on stainless screws 19 and hook 20. In this case, the transition stainless plate 13 abuts the nozzle 4, and the length of the rod 7 corresponds to closing the opening 14 with the curtain.

On the upper part of the tube of the holder 2, a slider 8 is installed with the possibility of its movement along the axial slit 23 on a stainless steel screw 24 with a hole 25 for counter-wires. The rod 12 passes through the hole 26 and is mounted on the slider with a stainless screw 22.

A flexible hose 10 is inserted into the upper part of the tube 1 of the vas deferens, connecting the vas deferens 1 with the dispenser 9, fastened with Velcro to the hand holding the seeder. The triangular blade 11 is held by a free hand.

Seeds are sown as follows.

The dose of seeds is discharged by the blade 11 from the metering unit 9 onto the shutter 6 through the hose 10, tube 1 and hole 14. After that, the thumb of the hand holding the seeder by the holder 2 moves the slider 8, the shutter 6 opens, the seed dose freely drops to the sowing point prepared a furrower 5, from a height of 1.5-2 cm, without bouncing.
