COMBINED DEVICE FOR BIOMELIORATION OF STRONGLY ACIDIC SOILS WITH DESALINIZATION AND COMPLEX TREATMENT OF DEGRADED RAINFED LANDS

摘要

FIELD: agriculture; machine building.;SUBSTANCE: invention relates to the field of agricultural machine building. Combined device for biomelioration of strongly acidic soils with desalinization and complex treatment of degraded rainfed lands includes self-propelled base chassis with three-section frame with two mounted wheelpairs with paired wheels installed on each section of frame. On the first section of frame there installed is cabin of combined unit with computer, control processor with code GPS receiver of coordinates and control board of automatic switching on and off of drive of working elements. On the second section of the frame there installed is engine of basic chassis with flow divider, filter of exhaust gases, fuel tank and working fluid tank of hydraulic system with hydraulic pump, flow dividers and branch pipes. Branch pipe from exhaust gas filter is connected to ejector of product conduit connected with two-section container for organomineral components of fertilizer interlayer or water-regulating screen. Behind cabin there are two-section tanks for ameliorant with dosing units, shutoff device, pump connected by branch pipes with outlets of disperse ameliorant behind blades under plates of tillage machines. On the sides of the cabin front there are tanks for herbicides connected through the shutoff devices to the pump and branch pipe with nozzles under the moldboard, located behind the battery of cutting discs. Said branch pipes with nozzles via shutoff devices, flow dividers via pump, dosing unit and product pipeline are connected to container for mineral fertilizer NPK or phosphogypsum located on second section of frame. On the second section of the frame there is a three-section tiered volumetric deep cultivator composed of parabolic stands of rippers with inclined knife plates, moldboards, branch pipes and slotted outlets of the mixture. three-section tiered volumetric deep cultivator comprises central section in direction of movement with wedge-shaped moldboard between first and second strut posts of second transverse plane, as well as two side sections with the extreme post in the third transverse plane and the deep tiller post in the fourth transverse plane, recessed into the slot from the second post. All parabolic posts of the tiered volumetric deep cultivator contain a mechanism for automatic controlled locating and moving position of bits and knife plates in the depth of processing and hydraulic drive to transfer the ripper to the transport position. On the third section of the frame there arranged is a compressor, a product pipeline, seed containers, a container for a solution of nitrogen-fixing microorganisms, connected to a distributing head and a branch pipe fixed on a bracket of a disc ploughshare. Similar pneumatic sowing machines are arranged behind the frame of the third section and on its sides, and leveling-compacting device is arranged behind the stands of seed shoes for seeding-down.;EFFECT: reduced time of reclamation of degraded and increased productivity of agricultural lands.;5 cl, 5 dwg
