Description

one

The invention relates to agricultural machinery and may be used for sowing seeds of cereals, leguminous plants and grasses, as well as granulated mineral fertilizers.

A plant is known in which a brake device is installed behind the disks with tubes, which is kinematically connected with the shaft of disks with tubes, the latter being fixed on the disks at an angle ij.

However, such working bodies, when the humidity increases, become clogged with soil, which prevents the tubes from escaping with & n. When changing the physicomechanical properties of the SOIL1, the brake discs can slip and slow down the sowing discs insufficiently. In addition, such embedding workers have a complex structure.

Known spruce, including the frame with soil tillage working bodies and working bodies for planting, made in the form of

mounted on the axes of the hollow needle discs with seed outlets and hollow stands, the outlets are located on the back of the needles in an area free from soil pressure, and the needle discs are assembled in batteries and set at an angle to the direction of movement of the lk 21.

The hollow posts of such a plant are clogged with earth and the reliability of the technological process is reduced.

The purpose of the invention is to increase the reliability of the process. . This is achieved by the fact that the working body is made as a separate hole-forming disk with curvilinear needles and a sowing disk with cells along the outer diameter, set coaxially with the hole-forming disk, with the ends of the needles located in the plane passing through the geometric centers of the cells.

Claims (1)

FIG. 1 shows the proposed plant, side view; in fig. 2 - work 3. 7 organ, top view; in fig. 3 - crop, section. The seed consists of frame 1, seed bacon 2, a sowing disk 3 with 4 cells for seeds, a safety guard 5 and an ejector 6, a hole-forming disk 7 with curvilinear needles 8 fixed on the stage O. The machine has a sequential device of 6 each. -10 working bodies in each section. Each section has a seed pshk 2, the bottom of which is connected to the sowing disks 3 by means of rigid sem wires. The piping disks 3 have seed cells along the cylindrical surface. In the course of rotation, on the front of the sowing discs, to prevent the seeds from falling out of the cells, safety guards 5, 3 are installed. At the bottom, on the sowing discs, the ejector heads of 6 seeds are installed. For sowing two (three) seeds into each well, the sowing disk 3 has two (three) arranged cells 4, the number of which on each sowing machine is two (three) times larger than 8 on the louisinating disk 7, or the capacity of each cell allows la by. the appropriate amount of seeds. Sowing disk 3 with bolts 1O is rigidly attached to the hub of a 9 well-forming disk and coaxially with it. The hole-forming discs, along with the seeding, and the discs are mounted on the shaft. Their transverse movement on the shaft is prevented by sleeves 11. Safety guards attached to rigid seven wires and limited from transverse movements by collars and ejector 6. In order to be able to adjust the matching, the seeds get into the formed hole on the seed line 3 there are circular grooves 12 along which the seed disk 3, if necessary, is rotated during the adjustment process with respect to the needles 8 of the hole-forming disc 7. The seedling works as follows. During its movement along the field with needles, holes are formed in the hole-forming disc in a plane transverse to the direction of movement of the seed. When the disc-forming discs 7 are rolled, each needle 8 makes an oval hole due to the gradual deepening and displacement of its end to the line of longitudinal direction passing through the center of rotation of the disc of disk 7 in the direction appendicular to the direction of movement of the seed, ts seeds about hard sem wires, from which neither are seeded into shaped holes. The adjustment of the moment and position of the falling out of the grains from the cells 4 is accomplished by turning the seed disc 3 relative to the needles 8 of the hole-forming disc 7 in the circular grooves 12. At STOV, the bolts 10 are released, the seed seed 3 turns to the required angle and is set so that the cells are on one radial lines with needle ends. Then bolts 10 are tightened. The adjustment is made so that the grain falls into the hole when the needles 8 pass through the lower plumb position relative to the axis of the rotachonic embedding organ. In the upper part, the sowing disk 3 is connected to the seed box 2 through the hard seed circuit, where it is filled with the seeds of cell 4. After the sowing disk 3 is half a turn, the seeds are thrown into the well formed at this time. The needle 8, which forms the luiku, is at the time of the seeding of the seed from cell 4 in the hole; therefore, the seeds fall on its neck. In the course of further movement of the needle 8, as well as due to the influence of the neighboring needles 8, the walls of the hole are destroyed and the seeds are covered with soil. A change in the seeding rate per 1 ha is carried out by changing the angle of installation of the working bodies to the direction of movement of the unit and changing the sowing discs. At the same time, the number of formed holes and the corresponding number of seeds per 1 hectare changes.
