Description

(54) HEADER

one

The invention relates to the field of agricultural engineering, in particular to reapers.

Known reapers, including the body, the inclined chamber, the cutting unit, which is located above the reel, conveyor, divider, rotary rippers 1.

Their disadvantages are that they are very bulky and energy-consuming, because they are assembled as a separate aggregate, which is one of the housing, trailed and driving devices of inefficient working bodies, hydraulics, fasteners and other parts.

Attempts to hang or hit the rippers as separate units to the combine lead to a complication of the design and deterioration of the energy and operational parameters of the unit. In addition, the size of the unit increases, which has a negative effect on maneuverability and copying of the relief.

The purpose of the invention is to reduce the metal consumption of the device.

This goal is achieved by the fact that, in the proposed header, rotary rippers are different menus under the conveyor belt and are made in the form of tension belt springs ||, equipped with a drive.

Wah FIG. 1 depicts a header; view from above; in fig. 2 - rotary ripper.

The harvester consists of body 1, camera tilt 2, rear rotary ripper 3, divider 4, front rotary 1; o ripper 5, cutting unit 6, HJJ. which placed the reel (not shown in the drawing), as well as the drive mechanism; Hydraulic motors 7 and 8. Rotational loose 3 and 5 are made in the form of tensioning ley springs, fixed under the transport (not shown) and connected by hydraulic motors 7 and 8, connected to the hydraulic system of the header.

The outer diameter of the rotary knives is 120-170 mm. The front openings 5 are made in steps of S D / 2 (D is the diameter of the ripper 5) and rotate at a frequency of approximately 80 rpm. The pitch of the rear loose 3 is smaller than the front :; and they rotate at a frequency of about 150 rpm. This is ensured by the fact that a device 9 is mounted on the inlet of the hydraulic system with interchangeable throttling washers. Rippers 3 and 5 are sharply sharpened and consist of several sections. On the shaft 10 are fixedly mounted centering discs 11, to which the rippers are attached.

The design of the ZHRB-4.2 header makes it possible to mount the indicated rippers under the hull.

The conveyor (not shown) of the header should be made with a working length equal to the width of the header, otherwise the bevelled mass falls on the rippers, which leads to disruption of the process.

Rippers work in the following way.

The oil pumped from the combine's hydraulic system is supplied under a certain pressure to the hydraulic motors 7 and 8, which cause rotary rippers 3 and 5 to be driven by the rotary rippers 3, which must rotate with a greater angular velocity than the front ones. Thus, simultaneously with the mowing, a technological operation is performed - loosening the soil. A A A A A 17 V V V JLA ALL V V V V V

This header has a lower metal consumption and lower power consumption than the known one.

In addition, due to the occurrence of self-oscillations in the spiral ripper, due to the unevenness of the cultivated soil, self-cleaning from sticking soil and plant residues occurs intensively.
