Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to tillage machines for smooth plowing without heaps and open furrows in the shuttle mode.

According to the main author. St. No. 470258 is known for a frontal plow including a frame with connecting elements to the tractor's hinged system, support wheels, disc knives, elevators and plowshare left and right plow bodies, blades of the plowshares of which are set at an angle to the horizon so that the brushes of the plowshares of the neighboring buildings are touching. one another and are located in the same horizontal plane with the cutting edges of the lifters. In this case, the shares of the plowshares are located above the flow and are also in contact with each other, and behind the plow-pile plow bodies between the elevators, the press rollers made of corrugated ones are installed with adjustable height.

The disadvantage of this plow is poor-quality cutting of layers and instability of the course in depth. This is because

connection soils make it difficult to separate the outer layers, due to the undercutting of the disc with knives when turning them with plow-bottom surfaces, which also causes the depth instability on the soils with a specific resistance of more than 0.9 kg / cm.

The aim of the invention is to improve the separation of the layers and ensure the stability of the course in depth.

This is achieved by the fact that dividers made in the form of pyramids are installed at the junction point of the current shares of the neighboring buildings.

FIG. 1 schematically shows a front plow, side view; in fig. 2 - the same; view from above; in fig. 3 - divider.

The front plow contains frame 1 with connecting elements to the tractor's hinged system, support wheels 2, right-hand left-handed dump bodies 3 and 4, located in a row, at the junction of which are installed dividers 5, made in the form of pyramids, the top of which is a chisel 6 and can be made removable and attached to the bottom

side divider known reception, for example by welding.

The frontal plow also includes disc blades 7, rollers 8 for pressing layers of soil, equipped with pressure springs 9, the rigidity of which can be adjusted using the handwheel 10, as well as lifters 11.

Front plow works as follows

in a way.

When the tractor moves with the plow mounted, the frame 1 rests on the wheels 2 set to a predetermined depth. The disk knives 7 cut the soil into strips vertically on the ploughshare of the right- and left-turning housings, cut the formations along inclined planes and wrap them before joining them with rod surfaces. A divider 5 with a chisel b separates the seams along the bottom of the groove, where the disk knife 7 does not cut, and with the edges of the divider 5, extending to the window between the dumps, pushes and lifts the seams, contributing to their turnover. Closed seams fall under the rollers 8 and under the influence of the pressure springs 9 push the rollers to the bottom of the furrow between the lifters 11, contributing to the stability of the course along the depth of the plow.
