Description

one

The invention relates to the mechanization of work in forestry, in particular to machines for forest nurseries.

A known machine for mulching and embedment of seeds, seed spraying machine, substrate hopper, dispensing device and transfer box.

However, the substrate that is poured into the bunker requires preliminary screening, and when using different substrates, it is possible that they hang in the bunker and lumps, which significantly reduces the uniformity of seeding.

In the proposed machine for separation from the substrate of waste by-products in the process of mulching for delivery-dosage, they oscillate, use a net screen and a two-way transverse chute to divert waste between the spaces.

FIG. 1 shows schematically the proposed machine, the general view; in fig. 2 - kinematic diagram of the machine.

The proposed machine consists of a body 1 with a slatted or scraper conveyor 2, its bottom, and a transverse flap 3, a distributing sectional duct 4, a vibrating mesh screen 5, a double-sided transverse groove b, telescopic box-shaped guides 7 fixed on frame 8 of the section 9 for sowing machines.

The conveyor 2 and the transverse flap 3 together form a supply-metering

device.

The drive to the forest spike 9 is carried out by a chain transmission from the furrower roller / 6. The drive of the body conveyor and the oscillating rumble - from the power take-off shaft (PTO) right. The drive includes a chain drive 11, a gearbox 12, a chain gear 13 to the conveyor, a chain drive 14 and a crank mechanism 15 to an oscillating screen.

The mechanism for lifting the spike to the transport position consists of a two-armed lever 16, a hydraulic cylinder 17, a rod 18. When lifting the spindle into the transport position, the frame 8 and the lower ends of the guides 7 are raised.

The proposed machine works as follows.

When the aggregate is moving, the furrow forming roller 10 squeezes out seed grooves in the Soil, into which seed is fed by sowing devices through this wire. The conveyor material from the body / is supplied in an even layer (due to the damper 3 present in the body) to the oscillating screen 5.

Particles less than a mesh

The grids of the screen are sown through it and fall into the distributing section box 4, divided into several streams (according to the number of sowing lines in the tape). Further, using a telescopic box-shaped guide 7, the material is guided into the seed grooves.

Large (more than the mesh size of the screen) inclusions from the grid of the inclined screen 5 fall through the bilateral transverse trough 6 into the inter-belt aisle under the rear wheels of the self-propelled chassis.

Thus, due to the use of the oscillating screen 5 and the double-sided transverse chute 6, the need for preliminary sieving of the material is eliminated, and the seed is evenly distributed in the seed furrows. The waste sent between the rows is not an obstacle to mechanized care, since the interlocking device works during the run between the rows between the rows.

Subject invention

A machine for mulching and embedding of seeds, containing a woolen spreader, a hopper for the substrate, a dosing-feeding device and a distributing sectional box, characterized in that, in order to separate from the substrate, the secondary waste in the mulching process is followed by the dosing-dispensing device an oscillating screen and a two-way transverse chute are installed inclined to divert waste into the interstitial area.
