Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the quality of tillage and reliability. The cultivator has a stand 1 and a vertical shield 2 attached to it, which has a left-3 and a right-hand 4 flat-cutting elements (wings) displaced relative to each other in the direction of value I. The front edge of the shield is made in the form of one inclined to the other upper A and lower B parts, the intersection of which forms a sock. The angular and linear dimensions of the wings are assumed to be recommended for flat-cutting lancet paws, but the height of the lower part of the shield h relative to the plane of the blade of the wings is 30-35 mm, and the offset of the wing's toe I in the direction of travel and height h are determined by the ratio, 3. In this case, the smallest value of the height h of the lower part of the shield corresponds to the greatest longitudinal displacement of the wings. The cultivator foot satisfies the agrotechnical requirements for the treatment of vapors. The removal of moisture by paw from the lower layer of soil to the top (0-3 cm) does not exceed 5%. A vertical shield with a thickness of 5 mm with an obtuse angle of entry into the soil practically does not form a groove behind it, and there are no overhang of plants on the shield and wings. In general, the quality of tillage and the reliability of operation increase. The use of paws will reduce the resistance of the cultivator aggregate by at least 20% and eliminate the time costs, as well as manual labor for cleaning the paws from hanging vegetation. 4 il.

ABOUT

Fast enveloping of blades, paw deepening

The enveloping of the blades is reduced, the recess is slight,

groove missing.

There is practically no coating, there is a slight

soil spouting

There is no coating, the spouting increases, is formed

groove width up to 20 mm.

There is no coating, the spouting is significant, a groove is formed with a width of up to 25 ... 40 mm.

There is no covering, the soil is scattered, a groove is formed

more than 40 mm wide and up to 25-30 mm in depth.

Claims (1)

Claim A cultivating leg containing a stand, right- and left-side plane-cutting wings that are offset one from the other in the longitudinal direction, characterized in that, in order to improve the quality of soil cultivation and reliability in operation, the leg is equipped with a wing located between its wings and connected to them and with a resistant vertical flap with a front face having a lower and upper sloping one to another part, while the longitudinal displacement of the wings I 10 paws and the height h of the lower part of its flap is determined by the ratio l / h = 2-5,3, and the height n bo ttom of the flap respectively equal to 30-35 mm, while the smallest value of the height of the bottom flap portion 15 the longitudinal displacement of the wings will be greatest paw. Table 1 The performance of the experimental cultivator paws with an average processing depth of 6.3 cm and a unit speed of 9 km / h The height of the bottom of the shield, mm Some paw performance indicators fifty Rapid enveloping of blades, paw deepening 40 The enveloping of the blades is reduced, the recess is negligible, the groove is absent. thirty There is practically no enveloping, there is a slight gushing of soil 20 There is no enveloping, the gushing of soil increases, a groove is formed up to a width of 20 mm. 10 There is no enveloping, the gushing of soil is significant, a groove is formed up to a width of 25 ... 40 mm. 0 There is no enveloping, the soil is scattered, a groove is formed with a width of more than 40 mm and a depth of 25-30 mm. b FIG. 3
