Abstract

FIELD: agricultural engineering. SUBSTANCE: moldboard plow has moldboard bodies and furrow ripper made in the form of tine with hoe. Hoe point is positioned forward of moldboard of front body and is offset relative to body share toward soil layer pushing away side for distance equal to 0.4-0.9 of rear body width. Nonsymmetrical hoe has chisel of width exceeding that of hoe tine. Hoe wing is directed toward plow moldboard bodies. Plow of such construction provides effective thinning of subsurface layer, since furrow bottom is ripped upon passage of tractor wheels through furrow, with tractor wheels moving on solid plow bottom. EFFECT: increased efficiency, minimum manufacture and operating costs, reduced power consumption and enhanced reliability in operation. 4 dwg

Description

 The invention relates to agricultural production and agricultural machinery, in particular to dump plows.

 A known plow with asymmetrical paws placed behind dump bodies (SU 608496, A 01 B 13/08, 05/16/1978). This plow has less friction losses of the sidewalls (field boards) against the walls of the furrows. But the method of soil cultivation carried out by him contains the drawback noted above: when plowing with a three-, four-body plow, the tractor wheels move along the open furrow of the previous pass and compact its bottom, formed by a dump body and an additionally loosened paw. The driving conditions of the wheels along such a furrow are also deteriorating.

 The proposed technical solution is aimed at eliminating the noted drawbacks, at increasing the efficiency of decompression of the subsoil without worsening the conditions of movement of the tractor.

 The essence of the inventive plow for tillage consists in the fact that in a plow with dump hulls and a bladeless ripper in the form of a stand with a paw according to the invention, the toe of the paw is placed in front of the blade of the front body and is offset from the ploughshare of the front body towards the side of the formation falling off by a value of 0.4 .. .0.9 working width of the rear housing. In addition, the paw of the furrow ripper contains a bit whose width is greater than the width of the rack, and a wing directed towards the dump bodies.

 Figure 1 shows a diagram of the implementation of soil cultivation by a plow, figure 2 is a plow, side view, figure 3 is the same, a top view, figure 4 is a paw of a furrow ripper, side view A, figure 5 something same in plan.

 The plow includes a frame 1 with a hitch, dump bodies 2, skimmers 3, a circular knife 4, a wheel 5 with a screw mechanism for adjusting the depth of processing. The frame contains a bracket 6, on which is attached a removable bracket 7 with an L-shaped horizontal part and a reducer. Between the cheeks of the reducer, a bracket 8 of a furrow ripper is installed, consisting of a rack 9 and a paw 10. The paw contains a toe and a left wing directed towards the dump bodies. The toe has the shape of a bit, the width of which is b '' greater than the width b 'of the strut 9. The toe of the paw is offset from the ploughshare of the front body towards the side of the formation by a value l equal to 0.4 ... 0.9 of the working width B of the rear body. Groove rippers can also be installed behind all dump bodies except the last.

 When the plow passes the field for the first time, a furrow cultivator loosens the track of the tractor's right wheels moving along the field surface. This improves the uniformity of the depth of cultivation along the width of the plow, and the formation, falling off the first body, is laid on the trail of the ripper. Subsequently, when the right wheels of the tractor move along the furrow of the previous passage, the furrow cultivator loosely loosens its bottom before laying in it a layer discarded by the front body. Moreover, the depth h of loosening is 0.2 ... 0.6 of the width of the bottom In the open furrow. With a working width of 25, 35 or 45 cm this will be 5 ... 15, respectively; 7 ... 21 and 9 ... 27 cm. The depth of decompression is greater, the more powerful (heavy) energy is used in the implementation of the extended method of tillage. The established depth range always ensures sufficient destruction of the plow sole, additionally sealed by the tractor wheels.

 After treatment, the water-air regime of the soil improves, eliminating the possibility of the formation of water saucers, soaks and surface runoff.

 In addition, with moldless loosening of the bottom of the furrow, the most harmful effect on the soil of the tractor wheels is eliminated and the conditions of their movement along the furrow do not worsen. As a result of soil cultivation, its water-air regime improves, the depth of the root layer increases.

 Performing the toe of the paw is chisel-like and in width exceeding the width of its rack, increases its reliability and wear resistance.

 The asymmetry of the paw, the direction of its wing towards the dump bodies helps to reduce the load on the sides of the dump plow bodies, which ultimately reduces energy costs for implementing the method of tillage.

 During emergency loads on the furrow ripper, the lower bolt of the bracket 8 on the reducer is cut off, and the groove ripper, deepening, bypasses the obstacle without breaking.

Claims (1)

 A plow for dump tillage, including dump casings with plowshares and dumps and a non-moldboard furrow cultivator in the form of a stand with a paw, characterized in that the toe of the paw is placed in front of the plow of the front casing and is offset from the ploughshare of the front casing towards the side of the formation by an amount equal to 0.4 - 0.9 of the width of the rear housing, while the furrow ripper paw is asymmetrical and provided with a toe in the form of a chisel, the width of which is greater than the width of the leg of the paw, and a wing directed towards the dump bodies.
