Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the quality of soil preparation on ridges and crests. The device comprises a frame 1 provided with a support wheel 2. The air cutter 14 is placed on the frame 1, pivotally connected to the feeder 5, is located in front of the support wheels of sections 13 and is equipped with an adjustable stop 16. The center of weight of the wall cutter 14 is displaced forward in the direction of movement of the unit relative to the center the pivot points are with the reducer 5. Markers are fixed on both sides of the cultivator frame, and the equalizer and slits are fixed on the beam of the sections. When the machine moves, the furrow cutter 14 penetrates the soil to the required depth and cuts the furrow, while by cutting 12, moving below the bottom of the furrow, loosens the soil, which increases the soil moisture capacity, and the timber 10 levels the soil surface, forming a flat top of the ridge or c do 3 hp ff, 2 ill.

And, and) b | 1, the theory refers to agricultural enterprises of the 1st machine building industry, in particular to cultivators, mainly to nponauj plants.

lU .ii.H) and yoretspin is an increase in the quality of soil preparation on ridges and ridges.

FIG. 1 shows a schematic view of a cultivator-cresser of the dodelate, side view; in fig. 2 is the same, top view. The cultivator-combger dodelel consists nz ra. We 1, made in the form of a bar of rectangular section, on which the support wheels 2 are fixed, the hinged device 3, made in the form of automatic coupling, markers 4 and reducer 5. K Sections 5 are fastened to sections 5 by means of a hinged parallelogram hinge 6. An equalizer is attached to the iganga of sections 7 to align the tops of the crests and r {) d, including a lead 8 with a spring 9 and a triangular bar 10, which is connected by a flexible element 1I to the rod of section 7, the trimmer 12 and the support wheel 13 of the section. And): uiKpeiLicii P1arnarno. To reducers 5 P1 hingedly fasten; 1, fencing cutters 14, for example, by means of pillars 15, the deviation of the rear edges relative to the direction of movement is limited to the stop 16 with the locking bolt 17. At the same time, the grooved cutting edge 14 is fixed in such a way that its center of gravity (ct.t.) is displaced forward in the direction of movement relative to the center of its pivotally connecting with the reducer 5.

Cultivator-combger dodelate works as follows.

The unit enters a plowed field with a flattened surface, the cultivator is lowered into the working position with the help of hydraulic tools, lowers one of the markers 4, and the unit starts moving. In this case, the first pass is performed along cams, since t) T the straightness of the first pass also determines the quality of the formed g (10) in subsequent passes. The control valve lever, the control unit and the lowering of the frame, must be set to the “floating position. In this case, the frame 1 rests on the support wheels 2, which copy the relief of the soil surface. At the beginning of the movement, the ai regatta is a furrow cutter 14, pivotally attached to the reducer 5, due to the angle of entry of its toe, adjusted by a bolt 17 screwed in () p Ki. buried in the soil. The required depth of the furrow cutter 14 is adjusted by changing the position of the support wheels 2. When the machine moves, each of the furrow cutters 14 cuts the furrow, and between the adjacent furrow cutters, a ridge or pile is formed (depending on the number and placement of the furrow cutters). The support wheel 13 of section 7, fixed to the subductor 5 by means of a hitch 6, moves along the bottom of the furrow cut by furrow cutter 14 and holds a certain predetermined stroke depth of the working parts, for example slits 12. The sock of the slits 12 moves in the soil below the bottom of the furrows, loosens and thereby increases soil moisture in the furrow. At the same time, the bar 10 connected to the shchtang of the section 7 of the flexible rod 11 and pressed by the spring 9 put on the leash 8 aligns and forms a flat top of the ridge or pile convenient for locating the polosovid opener, for example cotton seed. Offset c. T. groove cutter 14 forward in the direction of motion relate: 1no the center of the center of the joint with its reducer 5 provides for xopoiuee to deepen its toe into the soil in each subsequent race. The fastening of the grooves to the undercuts excludes their lateral deviations. Therefore, all the spaces between the rows are the same. Later, when sowing, this ensures high-quality seed placement at the same depth exactly in the middle of the ridge.
