Abstract

FIELD: agriculture.

SUBSTANCE: mechanism for expanding and shifting the wheels of a self-propelled universal cutter on a hydraulic drive contains a hollow beam (2) integrated into the frame, having a cross section in the form of a rhombus. Inside the hollow beam (2) there are two sliders, on which the wheels (5 and 6) of the cutter are fixed. The sliders are mounted with the possibility of moving along the beam (2) and fixing on it in the range of positions from the transport position of the track to the position along the track width with the help of hydraulic cylinders (7) fixed on them and on the frame with hydraulic locks. The sliders are attached to the beam (2) also by means of support shoes (8).

EFFECT: expanding functionality, increasing reliability, improving consumer qualities and ease of use.

Description

The invention relates to the field of agricultural engineering, and specifically to self-propelled universal mowers (KSU).

Known similar in design mechanism for sliding the wheels of self-propelled mowers such firms as "MacDon", "AGCO", "CNH" and others [1. Information website - www.macdon.com. - MacDon Prospectus M Series Mowers, 2018. 2. Information website - www.newholland.com. - Prospect of the company "New Holland" SPEEDROWER SELF-PROPELLED WINDROWERS 2018. 3. Information website - www.agcocorp.com. - MF WR 9800 Series prospectus, 2018].

The closest in design to the claimed invention is the design of the self-propelled mower type M1240/1170 company "MacDon" [Information website - www.macdon.com. - MacDon prospectus M series mowers, 2018].

Mowers type Ml 240/1170 have a wheel extension mechanism, which is a rectangular hollow beam integrated into the frame, inside which two sliders are installed in one of two positions (two fixed positions of the drive wheel track), on which the mower wheels are fixed, while the sliders are fixed from moving along the beam with the help of fingers that are installed through the slider and the hollow beam.

The specified design of the mechanism for expanding the wheels of the mower type M1240/1170 has the following disadvantages:

1) there is no track width adjustment in a wide range;

2) there is no possibility of adjusting the width of the extension/movement of the wheels;

3) the procedure for installing the locking pin is inconvenient when the slider hole is aligned with the beam holes when performing operations of expanding/moving the sliders.

The objective of the invention is to expand functionality, improve reliability, improve consumer qualities and ease of use.

The technical result is achieved by the fact that the mechanism for expanding and sliding the wheels of a self-propelled universal mower on a hydraulic drive, which includes a hollow beam integrated into the frame, inside which two sliders are installed, on which the mower wheels are fixed, characterized in that the hollow beam has a cross section of in the form of a rhombus, and the sliders are mounted with the possibility of moving along the beam and fixing on it in the range of positions from the transport position of the track to the position along the track width with the help of hydraulic cylinders with hydraulic locks fixed on them and on the frame, while the sliders are also attached to the beam by means of support shoes, by preloading the support shoes, the backlash of the position of the sliders on the beam is eliminated, and by moving the rods of the hydraulic cylinders, the sliders move along the hollow beam, thereby providing a range of track width changes.

The claimed device is shown in Fig.1 - 3:

- figure 1 - hollow beam with a diamond-shaped section, integrated into the frame;

- Fig.2 - General view of the slider KSU wheel (right slider);

- Fig.3 - General view of the frame with sliders, hydraulic cylinders and support shoes.

The inventive mechanism for sliding and sliding wheels includes the following structural elements: 1 - frame; 2 - a beam with a diamond-shaped section;

3, 4 - sliders (right and left); 5, 6 - wheels (right and left); 7 - hydraulic cylinders with hydraulic locks; 8 - support shoes, while beam 2 is integrated into frame 1 and is part of it, sliders 3 and 4 are installed in beam 2 and are attached to the beam by means of hydraulic cylinders 7 and support shoes 8. Wheels 5 and 6, in turn, are attached to the rotating part sliders 3 and 4 bolted connections.

The claimed invention works as follows. When the KS U moves at low speed, the rods of the hydraulic cylinders 7 move. Due to the movement of the hydraulic cylinders, the slider 3 or 4 smoothly extends along the diamond-shaped beam 2 integrated into the frame 1. The driving wheels of the KSU 5, 6 are fixed on the sliders 3 and 4. Due to the extension of the sliders 3 and 4 there is a smooth change of gauge in a wide range. The sliders 3 and 4 are fixed on the beam 2 by hydraulic cylinders 7 on which hydraulic locks are installed, and when the support shoes 8 are pressed, the gap (backlash) between the beam 2 and the sliders 3, 4 is eliminated.

The technical result consists in providing the functionality of changing the track width in a wide range, in improving consumer qualities and ease of use.

Claims (2)

1. The mechanism for expanding and sliding the wheels of a self-propelled universal mower on a hydraulic drive, which includes a hollow beam integrated into the frame, inside which two sliders are installed, on which the mower wheels are fixed, characterized in that the hollow beam has a cross section in the form of a rhombus, and the sliders installed with the possibility of moving along the beam and fixing on it in the range of positions from the transport position of the track to the position along the track width with the help of hydraulic cylinders with hydraulic locks fixed on them and on the frame, while the sliders are also attached to the beam by means of support shoes. 2.
