SU129883A1 - Attached soil tillage sowing unit - Google Patents

Description

Various tillage machines are known that can simultaneously sow and embed seeds with rolling rows; However, these devices produce tillage with a turn of the reservoir, which leads to the loss of soil moisture, and are not adapted for loosening individual layers of soil, layer-by-layer cutting of weeds and automatic cleaning of working bodies from plant residues. As a result, they are unsuitable for the cultivation of agricultural crops. crops, and especially for summer recurring and planting of crops such as maize and sunflower. The proposed mounted unit eliminates these shortcomings and is different t known devices in that it uses soil-cultivating bodies that perform layer-by-layer tillage and weed cutting, with a small-combed loosening of the nlast without wrapping it, and carefully leveling the soil to ensure even planting of the seeds, resulting in summer repeated and crop sowing as well as for spring noses, optimal conditions for development are created.

The unit consists of several sections of the working bodies mounted on a square cross-section bar.

FIG. 1 shows a diagram of one secnin assembly, side view; in fig. 2 - the same, top view.

The main tillage organs of the section include lancet flat-cutting legs 1 and 2, mounted on the mountain. at different levels. The front, wider paw, U, is intended for loosening the upper layer of the soil and cutting the weeds, while the rear paw 2 is for loosening the underlying layer. The unit consists of (third-order e-paws (not shown in the diagrams) intended to loosen the strips of soil that remained intact between the front parts No. 129883

rock-gripping paws, and 4 units installed directly on the square beam.

In front of the wide-grip caps, a disk 5 is placed on a vertical rack, which is used to cut scabbards and protect the paw from clogging, and behind it is a night grinder 6, consisting of several rotary needle discs and mounted on a spring suspension 7- For the formation of a seed groove behind of the soil crusher is positioned on the frame 8 of the sowing apparatus, furrow 9, consisting of two angularly adjustable thirteen disks. After the furrow, the seed meter 10 is mounted on the frame with the soschnik //, Qdim effect of the rubber roller 12, walking on the p order, and its top packer under pressure of its own weight of n reguliruyupgego pressure spring 13 of the mechanism 14. The rear roller 15 is mounted disc earthing devices.

The main purpose of the unit is summer sowing, without breaking up with tillage, repeated and crop crops. This unit can also produce spring sowing on land without preliminary cultivation. For the application of mineral fertilizers, tukovysevayuschie devices can be additionally installed on the frame of the unit, with fertilizer feedstock directly under the cutting feet.

Subject invention

A mounted soil-cultivating and sowing unit, consisting of boring loosening paws, sowing machines with disc pins, rollers and disc zagorcha, characterized in that, in order to exacerbate the layer-by-layer soil tillage and loosen it well without turning the formation and creating an even bed for sowing In this unit, three types of flat-cutting paws are used in the unit, with different grasp widths and different tillage depths, with a device to eliminate the clogging of paws in the form of circular knives, which are not in front of the front gripping small-loosening paws and a device for carefully loosening and leveling the soil in the form of rotor hoe disks, reinforced several pieces behind the tillage paws.
