(54) DEVICE FOR CUTTING BRORES

one

The invention relates to agricultural machinery, in particular, tools for cutting furrows during the formation of a row, ridges for sowing vegetable crops.

A tool is known for cutting furrows, forming a ridge, ridges, and laying temporary irrigation canals, containing a combination of plowshares, dumps, discs, rollers, and various levelers with compactors 1.

The disadvantage of this gun is the poor-quality cutting of furrows, the formation of the ridge, ridges and laying of irrigation canals due to insufficient cutting, crushing and ejection of the soil by the working bodies.

The closest in technical terms to the proposed is a device for cutting furrows, including a frame, disk mills arranged at an angle to the horizon for forming the walls of the furrows and equalizer 2.

However, the device is characterized by insufficient cutting, crumbling and vybrasyvanie soil, which leads to poor-quality cutting channels. When working primer, fall under

milling tools, not fully crushed and thrown from the bottom of the furrow, remaining in the form of lumps. The ground taken out by the cutters is not leveled and lays down in the form of a ribbon web or by mounds on either side along the furrow.

The aim of the invention is to improve the quality of the cut furrows.

The goal is achieved by the fact that the device is equipped with a plowshare with side panels placed in front of the cutters, and the cutters are mounted on these side frames.

FIG. 1 shows a device for cutting furrows, side view; FIG. 2 - the same plan view; in fig. 3 - view of the working body and the main nodes.

The device for cutting the grooves consists of a supporting frame 1 with a connecting device 2, symmetrically arranged sharers 3 with sidewalls 4, on which disk milling cutters 5 with cutting knives 6 and rippers 7 are fixed. The sides, in turn, are connected to the reflector casing 8, on which the articulator 9 is hinged with a spring device. Rear, perpendicular to plane 1 of sidewalls, plates 10 are rigidly fixed, and in front of the sidewall they end up with rigidly fixed plates (throwers) 11. The drive of disc mills is carried out from the tractor PTO through a gearbox 12 and cardan gear 13. The depth of cutting of the furrows is adjusted by support wheels 14 The device works as follows. Before starting the support wheels 14, the depth of cut of the furrows is necessary. The tractor's PTO is then engaged and the clutch pedal is gently lowered. At the same time, the torque from the tractor VOM is transmitted to the disk cutters 5 via the gearbox of the drive 12 and the cardan drive 13. When moving the tools of the plowshares 3, the ground is cut, spread into two equal parts and fed to the disk mills 5. 4 and the plate 10, is subjected to fortification and scattering by rotating milling cutters on both sides of the furrow. The soil loosened by the mills at the moment of contact with the casing, the reflector 8 finally crumbles and, additionally leveled and compacted by the leveling device 9 and the pressure device, is evenly distributed on both sides of the furrow. The walls of the furrow are compacted by the same plates 10. It should be noted that the soil that was accidentally thrown out when trimming plowshares. Striking the plate (chipper) 11, back falls under the plowshare, and the likelihood of the cut soil falling to the bottom of the furrow is virtually eliminated. After the passage of the proposed tool, an evenly compacted surface of the wall and the bottom of the furrow is obtained, the depth is uniform, and the soil is evenly distributed and compacted, thrown out on both sides of the cut furrow. The annual economic effect from the introduction of one tool for cutting furrows will be 220 rubles. Claims The device for cutting furrows, containing a frame, angled disk mills for shaping the walls of furrows and an equalizer, characterized in that, in order to improve the quality of the furrows to be cut, the device is provided with a sideshare with sidewalls placed in front of the mills, and the cutters are set to these sidewalls.
