Abstract

FIELD: agricultural engineering, in particular, technique for tillage of soil on the fields with prevailing precipitation moisture-impermeable portions.

SUBSTANCE: tillage apparatus has rectangular welded frame with hanger system, tillage depth adjustment system, working tool attachment system, and working tools made in the form of tines with beveled lower part. Bracket with opening is fixed to mid portion of each tine. A-shaped half-hoes are pivotally secured at sides within openings by means of fastening pins fitted with threaded ends. Half-hoes may be folded and unfolded and have retainers for fixing said half-hoes in predetermined position. Tines have rectangular section, with lower front part formed as knee. Each tine is provided at its front side with triangular chisel having pins for attachment to tines and threaded openings. Additional brackets with openings are mounted in rear part of tines. Fastening spindles are screwed into chisel threaded openings through apertures provided in brackets located in middle and rear parts of tines, said spindles being adapted for fixing of A-shaped half-hoes through tubular brackets equipped with rotational angle restricting devices. Trapezium-shaped stirrers are mounted on half-hoes.

EFFECT: reduced consumption of power and enhanced reliability in operation.

Description

The invention relates to the field of agricultural machinery, in particular to devices for tillage with a predominance of areas that do not allow moisture to rain.

Known devices designed for deep loosening of soil from 40 to 80 cm: chisel plow ПЧ-4,5; cultivators deep rippers type NR-80B; ChKU-4; KZU-OZV, including chisel-like paws [see “Agricultural systems in the Krasnodar Territory for 1990-1995 and for the period 2000: Recommendations. VASKHNIL, All-Russian Branch, Krasnodar Research Institute of Agriculture named after P.P. Lukyanenko, Kuban Agricultural Institute. Krasnodar, Book Publishing House, 1990, p. 59, 128, 260].

The disadvantages of these units are low technological (functional) capabilities: only chisel.

The closest to the achieved economic effect and technical essence is a chisel mounted plow, including a rectangular welded frame with hitching systems, adjusting the depth of tillage, fastening the working bodies and working bodies in the form of struts with a beveled lower part having a bracket with a hole located in the middle of the rack in which by means of fastening axes with a thread at the ends the lancet half-arms are pivotally fixed on the sides with the possibility of folding and unfolding (see RU 2144749 C1, 01/27/2000).

The disadvantage of this device is the low operational reliability of the working body due to threaded fixation in the unfolded state, as well as high energy costs due to participation in the loosening of the rack.

The technical solution to the problem lies in the fact that the device for subsurface tillage will reduce energy costs, improve operational reliability, ease of operation when dismantling a bit for sharpening and its installation.

The solution to the problem lies in the fact that in the device for processing the soil, consisting of a rectangular welded frame with hitch systems, adjusting the depth of tillage, fastening the working bodies and working bodies, made in the form of racks with a beveled lower part having brackets located in the middle of the racks with an aperture in which, by means of fastening axes with a thread, folding and folding lancet half-arms having position fixers are pivotally fixed at the ends, the racks being made square cross-section with the lower front part in the form of a knee and equipped on the front part with a triangular-shaped chisel with pins for fastening on racks and with threaded holes, moreover, into the threaded holes of the chisel through holes in brackets located in the middle and back of the racks for mounting lancet half-legs the mounting axis is screwed through the tubular brackets, while the tubular brackets have angle-of-rotation limiters, and trapezoidal agitators are mounted on half-arms.

New elements are: additional brackets in the lower part of the rack from the front and back sides, and from the front side the bracket has the form of a triangular bit with threaded holes fixed with pins; the implementation of the bottom of the rack in the form of a knee; equipping half-arms with rotation angle limiters formed by placing tubular brackets on their surface; and equipping the half-arms in the unfolded state with easily removable trapezoidal agitators.

The invention is illustrated by drawings, where Fig. 1 shows a diagram of a device, a straight view, Fig. 2 shows a top view, Fig. 3 is a side view, in Fig. 4 is a section A-A, in Fig. 5 is a section B -AT.

The soil treatment device consists of a rectangular welded frame 3 with hitch systems 1, adjustment of the soil tillage 2, fastening of the working bodies 4 and working bodies 5, made in the form of uprights 6 with a beveled lower part, having brackets 9 s located in the middle of the racks 6 a hole in which, by means of fastening axes 14 with a thread at the ends, folding and folding lancet half-arms 10 having position locks 12 are pivotally fixed at the ends, the posts 6 are made of rectangular cross-section with a lower front the second part in the form of a knee and equipped on the front part with a chisel 7 of triangular shape with pins 8 for mounting on racks with threaded holes, moreover, into the threaded holes of the chisel 7 through holes in the brackets 9 located in the middle and back of the racks for attaching pointed half-holes 10 the mounting axis 14 is screwed through the tubular brackets 11, while the tubular brackets 11 have a rotation angle limiter 12, and trapezoidal agitators 15 are mounted on the half-arms.

A device for tillage works as follows. To carry out the technological operation of deep loosening, dismantle the agitator 15, strap 18, screws 19 and bushings 20 and, by turning on the axes 14, lift the half-holes 10 upward by an angle of 90 ° and fix them with a threaded joint 16, 17. When the unit moves along a corral set to the required depth machining with support wheels, brackets (chisel) 7 and half-arms 10 adjoined to the stand 6 work like a chisel.

For surface (flat-cutting) tillage, the half-holes 10 are laid out horizontally, fixed with a strap 18 and screws 19. On the half-holes 10, agitators 15 are installed. When the tractor unit moves, the brackets 7, which look like a triangular bit, cut a furrow and cut the soil, and half-holes 10 tear off the soil layer cut by an arm 7 with a width of 500 mm, the peeled layer is crumbled with a bit 7 and agitators 15. During operation, the half-pressure 10 is affected by soil pressure. Thanks to the additional brackets 7 and 9 installed in the front and back of the rack 6, reliable fixing of the half-arms 10 by means of the axis 15 is provided, the limiters of the rotation angle 12 provide more reliable fixing of the half-holes 10 in the unfolded state.

Due to the ease of installation and dismantling of the bracket 8, the axles 15 and the half-hole 10, the recovery cycle of the cutting properties of the bit 7 and half-hole 10 is reduced.
