Description

The proposed utility model relates to agricultural machinery and can be used for land reclamation, in particular for cutting drainage slits and pumping filler into them.

There is a known “device for cutting cracks in the soil with simultaneous introduction of mulching material into them,” which consists of a slot-cutting working body with a ploughshare and a hopper installed on the frame, from where the cracks are filled with mulching material by means of finger augers [1] and “a device for cutting water-absorbing slots with simultaneous introduction of organic filler into them” [2], which contains a hopper for filler, a longitudinal and two transverse conveyors, a multi-blade thrower, a slot cutter with augers and a storage funnel.

The closest device to the claimed object in terms of the set of features is a “tool for cutting slots with simultaneous introduction of filler into them” [3] (prototype), including a slot cutter with side walls made with longitudinal grooves and a device for feeding filler into the slot in the form of a hopper.

The disadvantages of these devices are uneven supply of filler into the slot due to poor fluidity, uneven and insufficient filling density of the slot, as well as clogging of the slot cutter with filler, despite the slots in the side walls.

The purpose of the development is to ensure dense and uniform injection of the filter material (sand pulp) into the crack to prevent subsequent backfilling of its walls.

node B is an option for attaching the slot-cutting working element to the frame cross member.

To achieve a new technical result, the slitting drainage agricultural unit is composed of a frame 1 mounted on a tractor, on which slitting working bodies 2 with chisels 3, support wheels with adjusting mechanisms 4, a hopper 5 for filler 6 are installed, and a slurry pipeline 7 of rectangular cross-section is attached to the slitting working body , in the rear wall of which there are slots 8 in the form of windows, while the width of the slurry pipeline 7 itself does not exceed the thickness of the slitting working body 2, and in the funnels 9 of the hopper 5 screw pumps 10 are mounted with a drive 11 from the power take-off shaft, connected to the slurry pipeline 7 for injection filler (sand pulp) 6 from hopper 5 in slot 12.

The slot drainage agricultural unit works as follows. Before starting work, the unit is mounted on a tractor and the slotting depth is set using the adjusting mechanisms of the support wheels, and the hopper is loaded with filler (sand pulp). While the device is moving, the slitting working parts with chisels are immersed in the soil, cutting slits in it. Screw pumps, driven by the power take-off shaft, supply aggregate (sand slurry) under pressure into the slurry pipelines. Next, filler (sand pulp) is pumped into the cracks through slits in the rear walls and at the ends of the slurry pipes, filling them tightly. This eliminates backfilling of cracks and ensures their long-term functioning.
