Abstract

FIELD: agricultural engineering, in particular, tillage tools.

SUBSTANCE: motor plow has frame bar, control means, driving and driven wheels, passive working tool (moldboard) and engine equipped with transmission kinematically connected with propeller-mellower mounted on frame bar in parallel with longitudinal axis of transmission. Propeller-mellow is formed as caterpillar-type band having ground-engaging members formed as conical needles. Propeller-mellower is inclined in longitudinal-vertical plane. Propeller-mellower is additionally equipped with guiding rollers provided on pivotally fixed ground-engaging members and trough-type guides for forced setting of inclination angle of ground-engaging members relative to caterpillar-type band. Supporting wheel is fixed on front part of frame bar. Moldboard is secured in rear part of frame bar.

EFFECT: increased motive force of motor plow, reduced consumption of power for ground mellowing process, reduced adverse action of motor plow upon aggregate structure of ground.

Description

The invention relates to agricultural machinery, namely to tillage implements.

A mechanical agricultural implement is known, an analogue (SU 1128847, class A01B 3/50), containing the chassis mounted on the wheels, controls, drive and working body.

The main disadvantages of agricultural implements are:

- intermittent movement;

- power costs for moving the device without performing useful work on loosening;

- significant weight of the device, necessary to create sufficient pressure of the wheels to the soil and create traction for cutting and wrapping the formation;

- significant weight compacts and strengthens the loosening zone, which requires additional energy costs.

A well-known motor-plow, prototype (patent No. 2048044. Bull. No. 32, 1995), containing a frame beam, governing bodies, driving and driven wheels, a passive working body (blade) and an engine with a transmission, the last of which is kinematically connected with the propulsion a ripper mounted on the frame parallel to its longitudinal axis, the ripper-ripper is made in the form of a caterpillar belt with tipping needles in the form of conical needles and is inclined in a longitudinally vertical plane relative to the horizontal plane, and is fixed in front of the frame beam support wheel.

The main disadvantages of a motor-plow are:

- spreading and spraying the soil at the exit of the soil;

- energy costs for lifting the chipped mass of soil;

- additional stresses in the circuit when loosening.

The objective of the invention is to increase the traction force of a motor-plow, to reduce energy costs for loosening the soil, to reduce the impact of the mover-ripper on the aggregate structure of the soil.

The problem is solved as follows

The motor-plow contains a frame bar, governing bodies, driving and driven wheels, a passive working body and an engine with a transmission, the last of which is kinematically connected with a ripper mounted on the frame parallel to its longitudinal axis, the ripper is made in the form of a caterpillar track with hoists in the form of conical needles and is located obliquely in the longitudinally vertical plane relative to the horizontal plane, and the support wheel is fixed in front of the frame beam. The mover-ripper further comprises guiding rollers on pivotally mounted couplings and guiding chutes for forcing the angle of inclination of the couplings relative to the track.

The drawing shows the proposed motor plow, side view.

The motor-plow contains a frame beam 1, a support wheel 2, an engine with a transmission mounted on a frame beam 3, control elements 4, a blade 5, articulated couplings 6, a drive wheel 7, a moving ripper made in the form of a track 8, guiding channels 9, driven wheel 10, guide rollers 11.

Motor plow works as follows.

From the engine with the transmission 3, the movement is transmitted to the driving wheel 7, rewinding through the driven wheel 10 the track of the mover-ripper 8 with the hooks articulated on it 6. The supporting wheel 2 when loosening perceives the weight of the device partially and completely during transport crossings.

Since the mover-ripper, namely the caterpillar track of the mover-ripper 8 with the link arms 6 pivotally mounted on it, is rewound by the driving wheel 7 along the follower 10, it is mounted obliquely to the surface to be machined, i.e. the support wheel 2 is located higher than the drive wheel 7, there is a smooth immersion of the couplings 6 in the soil with a low weight plow. With the introduction of tillers 6, the reaction of traction force is transmitted as a reaction of soil resistance to wedging, which is attached to the frame beam 1 and the dump 5 attached to it.

Under the influence of the traction force, the motor-plow moves, while the blade 5 dumps the loosened soil into the furrow. When moving the motor-plow, the caterpillar track of the mover-ripper 8 is rewound, the pivotally mounted tiller 6 approaches the driven wheel 7 and the guide rollers 11 begin to exit from the guide grooves 9, which gives freedom to the tipper 6 to change the angle of inclination relative to the track of the mover-ripper 8, which changes direction. Soil pickup 6, which has some freedom to change the angle of inclination relative to the track of the mover of the cultivator 8, when leaving the depth of the soil changes the angle of inclination in such a way as to ensure a minimum of energy consumption for loosening the soil. The support wheel 2 partially perceives the weight of the device; through the controls 4, the operator adjusts the working width and the operating mode of the engine 3.

The use of the invention, which is based on the principle of a varying inclination of the hook relative to the caterpillar track of the mover-ripper, will reduce the energy costs of throwing and loosening the soil and create additional traction due to the vertical exit of the hook from the ground.
