Description

Forest mounted seedlings for row-well sowing of tree and shrub species, consisting of a frame, a seed bunker with a sowing box and a scoop-type sowing device, devices for forcing seed from the bunker to the sowing box, drive wheel, opener, spoiler and the scheduler is known. Such crops do not always emit specified portions of seeds of various sizes and shapes and do not place them along the bottom of the furrow for the required distance between portions.

In the described plant, this drawback is eliminated by the fact that the seed metering unit, located in the seed part of the box, is made in the form of a coupling wheel rigidly mounted on the drive shaft, equipped with six radially mounted sleeves that carry in place rigidly fixed replaceable holder of blade-shaped elastic plates required sizes. The latter are set at an angle and, being in the seed material, when moving along the cylindrical bottom of the box, they seize certain portions of seeds, lift them up and throw them through the nut into the vomer.

The drawing shows the proposed plant in three projections.

The frame / forts of welded construction is made of strip steel. It rests on a drive wheel 2, equipped with side gables 3. The wheel is rigidly mounted on a shaft 4 mounted on two bearings. Inside the frame, in its middle part, the seeding box 5, consisting of two parts - the receiving and seeding, is strengthened. There is a hole for moving the seeds from the receiving part to the seed in the vertical wall 6 separating them. The sowing unit, located in the cylindrical seeding part of the box, consists of a coupling 7 with six radial bushings for interchangeable holders of paddle-shaped seed plates 8. The coupling is rigidly mounted on the drive wheel shaft 4. The sowing elastic plates 8, depending on the shape, size of the sown seeds, as well as on the placement of the portions of the seeds in a row, are rigidly fixed in the sleeves of one, two, three or

six pieces at an angle to the wall of the seeding part of the box. For sowing different seeds, different sizes of plates 8 are used.

The welded structure's opener 9 has a triangular shape with a sharp cutting edge and side elongated cheeks covered from above to prevent the groove from being filled with earth when seeds are ejected through the box 5 flap. 8. On one side of the opener, which is located behind the seed box, there are two There are holes for fastening it to the frame from the inside and adjusting the depth of the stroke.

The seed bin 10 is rectangular in shape with a lid on top. At the bottom of the bunker goes into the receiving part of the box, having inclined walls in front and behind. In the side wall of the bunker against the sowing apparatus there is a viewing window with safety glass. An increase in the capacity of the seed bunker for some seeds (maple, hay, oak, apricot) is carried out by a special box without bottom inserted into the bunker.

To force the flow of non-flowing seeds and sows to the seed metering machine, it has a device consisting of a removable plug II located inside the receiving box, suspended from the ball crank 12. The reciprocating movement of the fork along the inclined bottom is provided by the rotary movement of the crank from the shaft wheels 2 using two cylindrical gears 13 and 14.

For forced feeding from the bunker to the sowing box of large loose seeds (oak, apricot, cherry plum, plum), a device made in the form of a spherical disk 15 with fingers rigidly mounted on the shaft 4 at the vertical wall 6 of the receiving box was used. Flowing of small and medium-sized seeds of elder, acacia, cherry and others is carried out without any agitators.

The compaction of the groove bottom and the cutting of weed shoots is done by a double-sided paw 16 placed in front of the opener. The strut of the paw perceives weeds, creating more favorable conditions for the opener. Ahead of the creek there is a planner 17 of a concave shape, rearranged in height. The grip width of the planner allows the wheel and the vomer to move along a flattened surface, providing a uniform seed embedment depth.

At the back of the coulter, a stopper 18 is fastened to the frame, consisting of two plates at an angle to the line of movement, in order to cover the seeds in the groove with earth.

To clean the wheel rim from the adhering earth, a scraper was put, pressed to the rim with the help of a counterweight 19.

Ahead of the frame / reinforced two fingers 20 for the fork connecting the spike to the tractor hitch with a hydraulic lift. The tractor is mounted on a tractor or mounted tractor hitch equipped with a hydraulic lift with hinges. Depending on the type of seed, the seeds are equipped with appropriate seed plates. The seed embedment depth is set by rearranging the vomer in height, and the undercut of the paw is set to the same depth.

For the work of the plant, it falls to the ground, when it moves, the planner shifts the lumps to the sides, cuts off bumps and falls asleep, the vomer sinks into the soil and forms a groove in it.

The wheel, rolling over the arable land, rotates the shaft, on which the seeding elastic plates are fixed. In a circular motion, the plates are periodically immersed in the seed, moving it in front of it, pressing it against the cylindrical wall of the seed box, ending approximately at the level of the center of rotation of the plates. Raised seeds from the inclined plane of the plate through the threshold formed by the wall of the box are thrown into the cavity of the opener and to the bottom of the formed groove. The seeds laid in the groove are closed with earth, shifted by a plate flap.

The operating and transport position of the crop is transferred by means of a hydraulic lift.
