Description

The utility model relates to agricultural engineering, namely to the working bodies of tillage machines.

A device consisting of a rack, a flexible element such as a string is known. One end of the flexible element is attached to the foot, and the other - to the bracket located on the rack through a spring and an adjusting screw with a nut (SU No. 536768, IPC A01B 35/26,1976).

A disadvantage of the known device is the possibility of excessive accumulation of plant residues on a flexible element such as a string, as a result of which an increase in the traction resistance of the working body should be expected.

Closest to the claimed device is a combined unit with a universal tillage device, containing two wings, made in the form of two arcuate segments, the front parts of which are made with the possibility of displacement around a common fixed axis, rigidly fixed in a flat holder, the device is equipped with a mini-hydraulic cylinder, remotely connected by a wireless executive a mechanism with a hydraulic system of the unit and installed between the rear parts of the segments with the possibility of changing the working width (RU 206814, IPC A 01 B 35/20, 2020).

The disadvantage of the known design is that the segments are not protected from wear, which requires their replacement or restoration by various methods of surfacing.

The technical objective of the utility model is to protect segments from wear, reduce metal consumption, and increase economic efficiency.

The set technical task is achieved by the fact that an automated tillage unit containing two wings made in the form of two arcuate segments with a pointed outer edge and a sharpening angle (5 ... 7) °, the front parts of which are made with the possibility of displacement around a common fixed axis, rigidly flat holder mounted on the unit frame rack at an acute angle to the horizontal plane, the device contains a mini-hydraulic cylinder remotely connected by a wireless actuator to the unit hydraulic system and installed between the rear parts of the segments with the possibility of changing the width of the grip, according to the utility model, the working edges of the arcuate segments are equipped with replaceable cutting nozzles with rivets for their fastening, the length of each arc-shaped segment is 25 cm, the holder is rigidly mounted on the common axis from above, segments from below, the holder is made of a saber shape with an angle of inclination to the horizontal plane (40…45)°.

The utility model is illustrated by drawings.

SUBSTANCE: automated combined unit with a universal tillage device contains a sash 1, a lanyard 2, pivotally connected to the supporting frame 3, links 4 of a parallelogram mechanism 5 with front 6 and rear 7 beams, a frame 8, racks 9 mounted on it, a holder 10, segments 11 with overlays 12.

The supporting frame 3 contains longitudinal 13, adjustable 14 in width and transverse 15 beams. On the beam 13 there is a hydraulic cylinder 16 attached to the frame 3 with a hydraulic lock 17, connected to the carriage 18, on which the support and transport wheels 19 are installed.

Racks 21 are fixed on the rear beam 20 of frame 3, to which a drawbar 22 and a lever 23 with a bolt 24 are hinged, designed to adjust the height of the rollers. Lever 23 is pivotally connected to rod 25, on which spring 26 and a nut are mounted to adjust its compression. The drawbar 22 is pivotally connected to the brackets of the frame 27 of the roller section. By changing the length of the section of the thrust 28 between the holes for its fastening, the inclination of the frame 27 and the position of the rollers 29 and 30 installed on it with slat-toothed and tubular drums are adjusted in height relative to each other.

The drawbar 22 and the frame 27 of the rollers 29 and 30 are connected from above by means of a link 31. Such an adjustment is necessary when changing the total working depth and the inclination of the drawbar 22.

On the drawbar 22, a height-adjustable frame 32 is fixed with a harrow 33 with spring teeth and an adjusting rail 34 containing a number of holes that allow you to change the length of the section between the fingers for its attachment to the frame 27.

The automated tillage device consists of two arc-shaped segments 11 25 cm long, each. On the common axis 35, a saber-shaped holder 9 is installed on top with an angle of inclination to the horizontal plane (40...45)°.

The working edges of the arcuate segments 11 are equipped with replaceable cutting nozzles 12 with rivets for their fastening.

The implementation of each arc-shaped segment 25 cm long allows you to cultivate the soil with cutting weeds with a larger (up to 40 ... 45 cm) grip width than standard cultivator paws.

(The norm according to GOST No. 23.2.164-87 for cultivators is the use of universal shares of size three with a working width of 270 mm, metal thickness of 5 mm; as well as size five (B=330 mm, S=6 mm).

Increasing the length of arcuate segments up to 25 cm allows to increase the coverage up to (40...45) cm, such a selection of parameters allows pre-sowing strip tillage with a wider strip compared to the standard tillage width, which makes it possible to sow with an increased seeding rate. However, a further increase in the parameters of the segments leads to an increase in the traction resistance of the unit and fuel consumption.

Equipping the working edges of the arcuate segments with replaceable, riveted cutting bits for their fastening helps to protect them from wear, which leads to economic efficiency.

Saber-shaped holder 10 with an angle of inclination to the horizontal plane, which was set within (40 ... 45) °, since a larger angle increases the traction resistance of the unit and fuel consumption, and a smaller one, firstly, complicates the design of attaching it to the unit frame rack , secondly, it reduces the depth of soil loosening by the holder itself.

Combined unit with a universal tillage device works as follows.

Before starting work, on the holder 9, rigidly fixed on the common axis 35, through the holes 36 from below, two arcuate segments 11 are placed on top of each other through the holes 35 in their front parts and fixed through the holes 37 in the axis 35 with a cotter pin 38. On the segments 11 with rivets attach replaceable cutting nozzles 12.

The mini-hydraulic cylinder 39, connected to the hydraulic system of the unit, remotely sets the specified working width of the device (10 ... 45) cm.

When the unit moves, arcuate segments 11 with nozzles 12 cut the soil layer to the set processing depth and simultaneously destroy weeds. The holder 9 loosens the soil over the segments 11.

If necessary, the operator from the tractor cab reconfigures the segments 11 to the required working width remotely by a wireless actuator.

The use of the proposed tillage device will improve the economic efficiency of the unit, the quality of tillage, will protect the segments from wear, which will reduce metal consumption.
