FIELD: agriculture.SUBSTANCE: seeder-cultivator comprises a hitch, track rollers, a hopper, seed drills, a device controlling the supply of seeds or fertilisers, and a frame with two transverse beams. On the beams the cutting units are mounted by clamps in two rows. The cutting units are arranged in the form of spherical discs mounted on the racks at an angle of attack and freely rotating in bearing assemblies. The second row discs are mounted with the offset relative to the first row discs with the opposite angle of attack. On the transverse beams the jaws are mounted pairwise and welded, interconnected by the panels on top. On the panels six brackets are mounted for hinge joint with the frame of one hydraulic cylinder and four adjusting turnbuckles. Two turnbuckles are connected with the hitch, and two - with the track rollers. The rollers are divided into three groups: central and two extreme. Each group of the rollers is fixedly mounted on an additional axis, rotating freely in their own supports. The supports are mounted on the cranks, rigidly fixed on an additional transverse tube and pivotally connected to the frame jaws. On each of the three tubes the levers are rigidly mounted. Each extreme lever is pivotally connected to the turnbuckle located respectively above the frame. The central lever is pivotally connected to the hydraulic cylinder. The cutting units are evenly located on the beams in the areas free from the jaws. On the frame a carcass is mounted, having a hopper located on it. The hopper is made heart-shaped, two-sectional, and has a built-in bucket conveyor, which input is connected to the hopper output, and the output is located above the device of seed distribution. From the devices of seed distribution the seed drills are distributed to each cutting unit. The drive for the bucket conveyor is formed from the extreme track rollers.EFFECT: constructive implementation enables to simplify the design of the device and to increase adaptability of the device and speed of tillage and seeding.4 cl, 7 dwg |
