Trailed cultivator KPS, Kgsh, pre-sowing processed KPPO-4, Kirovohradska region.

Trailed cultivator pre-sowing machine processed KPPO-4
The main purpose of the pre-sowing tillage cultivator is the main and pre-sowing cultivation of the soil with a moderate amount of plant residues.
One pass of the cultivator provides:
grinding and mixing plant residues with soil
100% weed destruction
continuous cultivation to a strictly specified depth.
leveling the soil, breaking up lumps and combing out the cut weeds with spring teeth
crushing, leveling and compaction of soil with ribbed rollers;
The above operations allow you to get optimal conditions for subsequent sowing.

The above operations make it possible to obtain optimal conditions for subsequent sowing. The design of the cultivator is a unit consisting of a central frame - the cultivator section, on which complete paw working bodies are installed, a rear battery of 2-row spring-tooth harrows and rollers, by means of rods attached to the rear beam of the frame. A hydraulic wheel mechanism is installed on the frame, which provides both transportation and operation of the machine as a support, setting and maintaining the depth of processing. The machine is connected to the power source (tractor) by means of a height-adjustable traction-coupling device with a coupling loop at the end.
the working body consists of two "C"-shaped posts and an arrow paw with a grip width of 270 mm.
spring rack made of strip 10x70 (steel 60s2A)
Rigid rack made of a square 25x25
The paws are arranged in 4 rows in such a way that the minimum distance between adjacent ones in a row is 650 mm, between rows - 480 mm, between adjacent ones in the plan - 210 mm, which provides an overlap of 60 mm with a working width of the paw of 270 mm.
The spring-tine harrow consists of a two-beam frame, on which teeth are installed in 2 rows with a pitch of 250 mm, with an offset of 125 mm. The frame is suspended on 4 leads on rods and is fixed with a limit chain. allowing unimpeded climbing upwards from the given walking level.
Plate (ribbed) rollers of 255 mm are attached to two rods through an adjustable safety-pressure mechanism, which sets the necessary depth of travel, the force of pressure of the roller on the soil.
The hydraulic wheel mechanism is designed in such a way that the rod of the hydraulic cylinder occupies two extreme positions:
Fully extended – transport position with a clearance of at least 300 mm.
Fully retracted is the working position. Regulating the depth of movement of the paw working bodies is achieved by turning the wheel bracket around the axis to the required angle by lengthening or shortening the screw tie-rods. One side of the lanyard is attached to the upper point of the cheek of the wheel mechanism, and the other side is attached to the bracket welded to the front beam of the frame. Shortening the lanyard leads to the lowering of the wheels and a decrease in the tread depth of the legs. The lengthening of the rope, on the contrary, leads to deepening of the legs. One-wheeled mechanisms are installed on the central frame, which ensure high transport stability and reliable copying of the relief and the required processing depth.
