Description

Self-propelled devices for tillage and sowing of seeds, comprising a frame on a wheel drive, an engine, a milling drum with a casing and gears for sowing seeds and tuk, are known.

However, such devices do not align the surface of the treated soils and, therefore, do not eliminate the main cause of uneven ripening of plants, which slow down their growth in declines.

In the described device, the noted defect is eliminated.

The device has the peculiarity that, in order to improve the quality of arable and sowing works, it uses a soil planner blade, mounted as a continuation of the casing of the milling drum, and the driving wheels of the device are designed as rollers that roll in the soil loosened.

FIG. 1 the device is shown on the side, and in FIG. 2 is on the top.

On the common frame / device in the front part of it is installed a conventional type disc spreader2 with a hopper 3 with a capacity of 0.5 lg.

The main working device for tillage in the device is a milling drum 4 with quick-detachable curved blades, usually used in processing mop turf and high stalks, or with field hoes used in tillage of old arable soil and weak meadow sod clover type ni, a .

The milling drum 4 is covered with a casing about from above, the extension of the rear part of which is the dump-planner 6 of the soil, mounted with the possibility of rearranging it in a vertical plane. Blade Planner B works like a grader blade, i.e. scrubs the hillocks of the soil and leaves the collected loose soil in depressions, which contributes to the uniform ripening of the plants. If, for example, when the meadows are rejuvenated, the sod should remain intact, then the blade-planner 6 is fixed in a raised position relative to the casing 5.

In front of the frame / is supported by the direction of the wheels 7. Driving wheels 6

The devices are arranged in two rows, each of which consists of two solid rollers on rubber tires of high permeability and, if possible, of low pressure. The gap between the rollers of each row of wheels is used for the differential 9, shifted with respect to the differential of the second row of wheels so as to ensure the soil rolling over the entire width of the device. The gearbox from engine 10 to wheels 8 has five speeds, of which four are workers and one is transport. The gearbox from the engines 10 to the milling drum has three speeds for adjusting the crumbling of the soil and crushing the sod at different speeds of the device.

On the back of the frame / put three w; ichnya grain on the crop //. A small trailed roller 12 was used to embed the seeds sown on the surface of the seed. 12. The openers of the seed // are made disk or anchor.

Engine 10 is placed above the vedush, their wheels 8, perceiving the entire weight of the device

To increase the uniformity of the depth of tillage with a milling drum 4 on new lands

In front of the guide wheels 7, connected to the steering wheel 13, knife-cutters 14 are mounted, clearing the way to the wheels. The tussocks and tubercuts that have been cut with a scraper knife are crushed with a 4) drum drum.

Tillage can be done without rolling, which is required on large bumps of sedge with sowing during the second pass of the device. In this case, it moves in reverse, i.e. wheels 6 forward, and the milling drum 4 runs upwards, throwing the soil over itself. The driver's seat for this occasion must be rearranged.

Subject invention

A self-propelled device for tillage and sowing of seeds, consisting of a frame on a wheel drive, an engine, a milling drum with a casing and mechanisms for sowing seeds and tucks, differs in that in order to improve the quality of arable and sowing works, in it, a soil planner blade is used, mounted as a continuation of the casing of the milling drum, and the driving wheels of the device are made in the form of rollers which are fed up with loosened ground.
