Description

The utility model relates to agriculture and can be used in multi-support irrigation machines of the DM "Kuban-LK" type.

A multi-support sprinkler trolley for calm terrain is known (Shtepa B.G., Nosenko V.F. et al. Irrigation mechanization. Handbook. Moscow: Agropromizdat, 1990, p. 211), containing a frame, two pneumatic wheels, a drive including an electric motor-reducer, two worm gearboxes and cardan transmissions.

The disadvantage of the well-known multi-support trolley for a smooth terrain irrigation machine is its low efficiency due to the presence of worm gears, and the installation of only one electric gear motor, which drives both the front and rear wheels simultaneously through cardan gears, causes unproductive losses (parasitic power) during movement.

A trolley of a multi-support irrigation machine for calm terrain is known (Ryazantsev A.I., Olgarenko G.V., Kashtanov V.V., Gorodnichev V.I. Multi-support low-energy circular irrigation machine. Russian Federation Patent No. 54287 U1, 2006), containing a frame, two pneumatic wheels, a gear motor drive mounted on both pneumatic wheels.

The disadvantages of the known multi-support irrigation machine trolley for calm terrain, as studies have shown (see table and Fig. 3), are the increased power costs for moving the trolley due to the emergence of an unproductive (parasitic) component, as a result of the mismatch of rolling conditions (by rutting, slipping, etc.), in the driving mode, of both pneumatic wheels.

Table

Power characteristics of the gear motor drive of the trolley of a multi-support irrigation machine for calm terrain

Bogie drive design options Values of the indicators Pneumatic wheel profile width B (track depth), cm Power consumption N, kW Pneumatic wheel profile width B (track depth), cm Power consumption N, kW Pneumatic wheel profile width B (track depth), cm Power consumption N, kW Pneumatic wheel profile width B (track depth), cm Power consumption N, kW N/B ratio With two leading pneumatic wheels 60
(5.0) 0.30 50
(10,0) 0.35 40
(15) 0.40 30
(20) 0.45 With one leading pneumatic wheel 60
(5.0) 0.26 50
(10,0) 0.28 40
(15) 0.30 30
(20) 0.32

Thus, when the width of the pneumatic wheel profile changes from 30 to 60 cm (track depth from 5 to 20 cm), the power consumed by the trolley during its movement is spent on overcoming rolling resistance and unproductive costs (parasitic component)), and amounts to from 0.30 to 0.45 kW.

With one leading pneumatic wheel of the bogie, the power is mainly spent on rolling resistance and varies depending on the width of the pneumatic wheel profile, within 0.26-0.32 kW, which is 15-29% less than similar indicators for a bogie with two leading pneumatic wheels.

The purpose of the utility model is to reduce unproductive (parasitic) power consumption for moving the trolley of a multi-support irrigation machine on a calm terrain by ensuring operation in the leading mode of one of the pneumatic wheels.

The stated objective is achieved by the fact that in the trolley of a multi-support irrigation machine for calm terrain, containing a frame, two pneumatic wheels, and a motor-reducer drive, the motor-reducer drive is installed on one of the pneumatic wheels, with a ratio of its power N to the width of the pneumatic wheel profile B ( ), equal to 0.002 (see table and Fig. 3).

Fig. 1 shows a self-propelled trolley of a multi-support irrigation machine for calm terrain;

in Fig. 2 view A-A in Fig. 1;

Fig. 3 - graphic dependence of the drive power of the bogie on the profile width of its pneumatic wheels for various modes of their movement.

The trolley of a multi-support irrigation machine for a calm relief contains a frame 1, two pneumatic wheels 2, a geared motor drive 3, and in order to reduce unproductive (parasitic) power costs for movement, the geared motor drive is installed on one of the pneumatic wheels 2, with the ratio of its power N to the width of the pneumatic wheel profile B ( ), equal to 0.002.

The trolley of the multi-support irrigation machine for calm terrain works as follows.

When electric power is supplied to the gear motor drive 3, the trolley containing the frame 1 and two pneumatic wheels 2 begins to move. In this case, in order to reduce unproductive (parasitic) power costs for movement, the gear motor drive 3 is installed on one of the pneumatic wheels 2, with the ratio of its power N to the width of the pneumatic wheel profile B ( ), equal to 0.002.

The efficiency of the utility model consists in reducing the unproductive (parasitic) costs of moving the trolley of a multi-support irrigation machine on calm terrain.
