Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to seedlings for continuous sowing of seeds.

There are known seedlings for continuous sowing of seeds, which contain a milling worker, the organ installed behind it is a faultless scattering device, communicated by this wire with a seed hopper dispenser. 3-10

The disadvantage of these forks is damage to the seeds during sowing due to the fact that the scattering device is made in the form of a screw distributor of seeds located across the movement.

The purpose of the invention is to reduce seed damage during seeding.

This goal is achieved by the fact that the diffusing device is made in JQ as a horizontal tube arranged across the motion with through holes along the entire length, and the tube is equipped with a drive mechanism

in reciprocating oscillatory motion along its axis.

FIG. 1 is a side view of the blue; in fig. 2 - the scattering device and the mechanism of its drive in a perspective view; in fig. 3 is a section A-A in FIG. 2

The mill contains a milling tool 1, a bunker 2 for seeds, a dispenser 3, for example, a standard coil seed meter, a seven wire, a tube 5 of a beamless diverter, a patching device 6 (for example, a roller). To protect against damage, the tube has a housing 7.

Claims (1)

The cylindrical wall of the tube 5 along the entire length has a number of main through-diffuse holes 8 and a number of compensation holes 9 located above the main ones. At the end of the tube there is a window with a funnel 10 for connecting the seed wires. To drive the tube in reciprocating co: The oscillatory movement is me3. 9 The drive of the drive is in the form of a vibrator, which consists, for example, of a cam 11, a roller 12 and a return spring 13- The vomer, the milling working organ and the sowing device are covered with a shield. Selka works as follows. When the machine moves, the dispenser both sows the flow of seeds in accordance with a given seeding rate. Through this wire k through the funnel 10, the seeds enter tube 5, and due to the reciprocating oscillatory motion of the latter, distributes its entire length, partially filling the tube volume to a certain height depending on the metering capacity. When the level of the seeds in the tube increases, their static pressure increases and, accordingly, in some limits B03pacTaet, the throughput of the main holes, i.e. synchronization of seeding through them with dispenser productivity is ensured. When an excessive increase in the level, which is possible with a significant deviation of the parameters of the seeds or the mode of operation of the vibrator from the optimal ones, leads to clogging of the tube, cessation of the movement of the seeds, their self-consolidation and cessation of seeding. To ensure reliable operation of the tube and prevent the seed level from rising above the optimum, a series of compensatory holes 9- are made over a number of main scattering holes 8. Reaching the level of otBerpsy 9, the seeds will begin to pour out more intensively, not allowing a further increase in the level and clogging the tube. At the same time, most of the seeds continue to diffuse through the holes 8, which ensure the greatest uniformity of their distribution over the field. The milling tool 1 with a working width equal to the working length of the tube 5 is set in front of it and deepened by an amount corresponding to a given seed embedment depth. The soil, thrown off by his knives, thanks to the small cross section of tube 5, flies over the latter and covers the scattered seeds. Since the seeds are brought to the end of the tube 5, the space above it is free, due to which the soil thrown away by the cutter evenly covers the seeds and maintains a constant depth of seeding. If necessary, the ground surface is compacted with a diffusing device 6. The proposed seed can ensure good quality of continuous sowing, excluding their damage during sowing. Claims of the invention for continuous sowing of seeds, containing a milling working body and a non-contact spreading device installed behind it, communicated by this wire with a seed hopper feeder, characterized in that, in order to reduce damage to the seeds during sowing, the scattering device is made in the form of a horizontal transversely placed tube movement with through holes all along the line, the tube being equipped with a drive mechanism in a reciprocating feFbHoe oscillatory movement along its axis.
