Abstract

The invention relates to agricultural machinery, in particular to machines for pre-sowing soil preparation and strip seeding of grass in the grass. The purpose of the invention is to improve the uniformity of the seed embedment depth by independently copying the micro unevenness of the relief by the coulter with the press unit. The tool consists of frame 1, the soil-processing part — milling sections 2, seeds 3 with openers 4 of the pressing part 5. Vertical arms 6 are mounted on the frame 1, to the bottom of which the pressing part 5 is fixed in the form of a spring-loaded wheel trolleys with 8 openers mounted on a kg / nstate 4. Each wheel 9 is located behind the opener 4 in the center of the lane. The spring 10 is mounted on the rod 11, the lower end of which is pivotally fixed above the heels of 9, and the upper one passes through 12 mounted on the rear bar of frame 1. Each opener 4 has a closed V-or oav section, facing forward and tilted from the vertical with the lower end back at an angle of 10 ... 30 & depending on the flowability of seeded seeds n. 1 hp ff, 3 ill.

Description

The invention relates to agricultural machinery, in particular to machines for pre-sowing soil preparation and strip seeding of grass in the grass.

The known machine for planting grasses, containing a frame, installed on it, is therefore a tillage part, a trailer and zagortach. -

A known machine for planting grasses in the turf, comprising a frame, a soil-cultivating part with an active drive of a crop truck with coulters and a press-down part.

The disadvantage of these tools is the low quality of the technological process, which consists in that the seeding rate and the seed embedment depth in the strip are violated when the machine is working

turf with the presence of microroughness relief and lack of reliability.

The purpose of the invention is to improve the quality of the process and increase reliability.}

The goal is achieved by the fact that the machine for planting grasses in the turf contains a frame with a rear bar and a support wheel, an active tillage tillage device, a spreader with coulters and a press unit, the latter is made in the form of a wheeled cart that is mounted on the frame by means of a hinge mounted to it the front part of the vertical bracket and hinged and located under each of the wheels of the cart of the spring-loaded rod, each of the openers of the

mounted on a trolley directly in front of its wheel. In order to avoid jamming of the spring-loaded rod, its upper end is located in the frame mounted on the rear beam of the frame.

In Fig. 1, a machine for planting grasses in turf is shown, general view; Figure 2 shows the seed wheel, side view; on fig.Z - that same e, side view.

The tool consists of frame 1, the tillage part — milling sections 2, cages 3 with openers 4 and press section 5. On frame 1, vertical brackets 6 are mounted, to the bottom of which the press part 5 is fixed in the form of spring-loaded wheel cart, with 8 openers mounted on brackets 4. Each wheel 9 is located behind opener 4 in the center of the strip. The spring 10 is mounted on the rod 11, the lower end of which is hinged above the wheels 9, and the upper passes through the rocker 12 mounted on the rear bar of the frame 1. Each opener 4 has a V-shaped cross section, facing forward and tilted from the vertical to the lower end back to angle of 10-30 ° - depending on the flowability of seeded seeds. The wheel 13 for driving the spindle 3 is mounted on the central beam of the frame 1 by means of the frame 14 of the brackets 15 and 16, is spring-loaded and can swing relative to the frame 1 on the horizontal hinge 17 through which the drive shaft 18 passes. The depth of tillage by milling sections is adjusted by means of wheels 19, the seeding rate — Norton box 20. By varying the pressure of the spring 10, the required density of the sub-top layer is achieved.

To prepare the machine for operation, it is necessary to set the required milling depth, usually 6-8 cm, the seed rate, the coulter installation angle, the seed embedment depth and the spring pressure.

The machine works as follows.

The tractor's power take-off shaft is turned on — the milling sections 2 rotate, start moving and the machine lowers into

working position. The milling sections 2 crush the upper sour layer of soil in the strip and flux it. From the wheel 13, copying the relief of the floor, through the chain

transmission, drive shaft 18, Norton box 20, the rotation is transmitted to Slake 3 (agitator and metering units). The seeds of meadow pasture grasses are fed to the coulters 4. which, with their V-shaped corner, move the soil apart and slightly thicken the groove, forming a seed bed. Then the wheels 9, followed by the coulters 4. each in its own lane, close the groove and roll the top layer of soil - the seeds are sealed. When the coulter 4 moves and the wheels 9 also perform the copying. If necessary, preseeding rolling is performed.

Thus the proposed instrument

allows to improve the quality of the technological process of sowing grass in the turf, which leads to an increase in the productivity of natural forage lands.
