(57) Abstract:Use: agricultural engineering and is intended for soil under cultivation of agricultural row crops cultivated on ridges. The inventive Dodger contains a frame 1, Lemeshko conveyor casing 2, the combined case 3 set of alternating relatively Lemeshko-dumping cases. Combination with a casing provided with a rotor 4. To the frame 1 by napahanga field before each Lemeshko-otvajnym housing attached storage battery 5, pairs of which before each combo case there is another disk battery 6, in forming the plan obtuse angle. Disk batteries 5 and 6 are at an angle to the direction of movement of the plow. 1 Il. The invention relates to the agricultural industry and is designed to handle the soil under crops cultivated crops cultivated on ridges.Know the tillage tool of conservation tillage, including a frame with a hinge mechanism, Lemeshko conveyor housing mounted on the frame, hung from raw field frame, which is at an angle to the direction of ASCI and cutting ridges and improvement of quality of formation of the ridges.This objective is achieved in that the plow containing a frame and mounted on the frame Lemeshko conveyor body equipped with combined parts set of alternating relatively Lemeshko-dumping cases. In addition, on the frame of the plow from napahanga fields rigidly paired batteries disks forming in the plan obtuse angle.As the plow before each combo case is the battery drives in pairs which side napahanga field before each Lemeshko-otvajnym housing is another battery of disks forming in the first obtuse angle, it provides the cutting and transportation of cut layer in the direction of the furrow formed Lemeshko-otvajnym body. As a result, if the crushing and processing of soil layer as a combined case is the formation of the ridge. As the plow is installed combined case, the result is a more complete crumbling of the soil layer is qualitative formation of the ridge.The drawing shows the proposed plow.The plow includes a frame 1, Lemeshko conveyor casing 2, the composite body 3 installed striped otnositel Lemeshko-otvajnym housing attached storage battery 5, pairs which before each combo case there is another disk battery 6 forming in the first obtuse angle. Disk batteries 5 and 6 are at an angle to the direction of movement of the plow.The plow works as follows.With the passage of the plow disks, rotating under the influence of the reaction of the soil, cut the top layer of soil and transported it to the side of the furrow formed Lemeshko-otvajnym body. Coming after the combined body produces the turnover of the reservoir with the simultaneous formation of the ridge. As a combined enclosure is equipped with a rotor 4, the rotor is the destruction of soil formation and better formation of the ridge. The PLOW frame containing installed on it Lemeshko conveyor housing, a battery located disks, characterized in that the plow is equipped with combined parts, each of which is made in the form of a plow body with a short blade and mounted behind the rotor, and the combined body has a relatively Lemeshko-dump in alternating order, with battery drives installed in pairs and are located in pairs at an obtuse angle from one another, and one bathplug.
