The agricultural machinery market offers the consumer a large selection of snow blowers. Often a person gets into a stupor, trying to find the right model for his walk-behind tractor. All rotary nozzles have the same structure and principle of operation. The only difference is in some technical characteristics. We will now consider snow blowers for walk-behind tractor Ugra NMB 1, and we will understand the principle of their work.
The principle of operation of rotary snow blowers
The principle of operation of the rotary snow plow is the same and does not depend on the model. The snow blower consists of a steel body, inside which the rotor rotates. It is set in motion by a chain drive, which, in turn, rotates thanks to a belt drive connected to the motor of the walk-behind tractor. The auger rakes the collected snow mass and directs it from the sides of the body to the center where the metal blades are. They push the snow out through the nozzle outlet.
A sleeve with a fitted visor is fixed to the nozzle on top of the body. Snow is removed along it. By turning the visor, they adjust the direction of departure.
Snow plow SUN
The principle of operation of this model of a snow blower for the Ugra walk-behind tractor is based on the same rotary mechanism. The SUN nozzle easily copes with the packed snow mass, of course, if the layer is not frozen. The use of a snowplow is justified on sidewalks, private territory adjacent to the house and in other places with a small area. The SUN snow blower is driven from the Ugra NMB-1 walk-behind tractor through a belt drive. The torque is transmitted to the auger by a gear reducer.
Let's take a look at the main characteristics of the SUN nozzle:
- The direction of snow throwing is regulated by a swivel hood. It is conveniently located near the steering wheel. The operator has the ability to make direction adjustments without stopping the walk-behind tractor.
- The auger is made of solid steel strip. This design is characterized by increased strength and more efficient operation.
- The skis on the lower part of the body provide easy movement of the nozzle on the snow cover. The adjusting mechanism allows you to set the height of removal of the layer of snow.
- A feature of the SUN snow blower is the ability to change the auger speed. To do this, there is a function that allows you to change the standard gear ratio of the chain drive 1.55 to an accelerated ratio of 0.64. Changing the speed of the auger is beneficial during run cleaning a thin layer of snow.
- The dimensions of the nozzle allow for a working width of 60 cm. The maximum height of the snow layer is 30 cm.
- Snow is ejected from the sleeve at a maximum distance of 8 m. This indicator is influenced by the rotation speed of the auger and the movement of the walk-behind tractor.
SUN is designed so that during operation the noise level from vibration of parts is minimal. The snow blower weighs 47 kg.
Mobile-K CM-0.6
The domestic model of the SM-0.6 snow blower is produced in the Smolensk region by the manufacturer Mobil-K. The attachment is designed for use with the Ugra walk-behind tractor and other similar analogues. The snow blower is recommended for private owners who have a country house or summer cottage. The design feature is the toothed auger. The knives quickly deal with even slightly icy crust on the snow cover. By rotating movements, the auger drives the snow mass to the central part, where the throwing blades are installed under the outlet nozzle.Snow is ejected through the sleeve at a distance of up to 10 m. The operator can easily change direction with a canopy during operation.
The maximum cutting height of the snow layer is 68 cm. But it can be adjusted, if necessary, with runners installed on the bottom of the body on both sides. The working width is limited to 45 cm. When working with the attachment, the walk-behind tractor must move at a speed of 2 to 4 km / h. A feature of the model is the presence of a two-stage snow removal system that allows you to change the speed of the auger. The SM-0.6 nozzle weighs about 42 kg.
The video provides an overview of the CM-0.6:
We have reviewed only two models of snow blowers. Attachments from other manufacturers can also work with the Ugra walk-behind tractor. The main thing is that they are suitable for the technical characteristics recommended by the manufacturer of the equipment.
The NMB1 snow blower for the Ugra walk-behind tractor does not remove snow, but a crackling sound is heard in the gearbox. How do I fix the problem?
