SU398720A1 - SNOW CLEANER FOR SNOW CLEANING IN HARDLY ACCESSIBLE PLACES - Google Patents

Description

one

The invention relates to devices for the mechanized clearing of snow, both around the trees during their winter season, and between them in order to obtain walkways.

Known snow plow having a building with a blade rotor and a motor with a shaft.

The purpose of the invention is to facilitate the snow blower and reduce the effort of cutting it into the snow massif.

This is achieved by the fact that holes are formed in the shaft body, in KOTopEjix fingers are placed with the possibility of radial movement, at the free ends of which weights are fixed, and the body is made with an internal cylindrical surface located eccentrically to the shaft and enclosing the fingers with weights.

FIG. 1 shows a snow plow, side view (with partial section); in fig. 2 - the same, rear view (with a partial cut); in fig. 3-diagram of the action of centrifugal force during rotation of the gzza.

The snow plow for snow removal in hard-to-reach places consists of a chambered housing 1, expansion sleeves 2, rubber shock absorbers 3, a plate 4, a driven sprocket 5, bolts 6, chain 7, a control handle 8, a gas tank 9, an engine 10, a helical-helical gear unit 11 , skin.ha

12 rotors, drive sprocket 13, chains 14, three-blade rotor 15, driven sprocket 16, bearings 17, rotor shaft 18, pins 19, weights 20, body 21 with a cylindrical surface, bearings 22, vibrator shaft 23, earrings 24, drive sprocket 25 , centrifugal clutch 26, fastening yoke 27, sandwich casing 28.

The snow blower works in the following way.

The rotation from the crankshaft of the engine 10 is transmitted to the drive shaft of the gearbox 11 through the coupling 26. From the gearbox 11, the rotation is transmitted in two directions. From the longitudinal output shaft of the gearbox through the chain gear (driving sprocket 13, chain 14 and driven sprocket 16), the rotation is transmitted to the rotor 15, which takes the blade by the blades and throws it through the hole in the skin. 12 to the right along the snow blower. From the transverse shaft of the gearbox 11, the rotation is transmitted to a centrifugal vibrator, the principle of operation of which is based on the use of centrifugal force of a variable value.

When the shaft 23 rotates, the fingers 19 and the weights 20 rotate with it. The fingers 19 with the loads 20 have the potential of a radial change 1, in the holes of the shaft 23, due to a change in the center of the load 2C

by the value of E from the center of the housing 21, from the distance: ntsts the radius of rotation from the hippmumble of the maximum, and consequently, the centrifugal force developed by the load 20 varies. Moreover, the maximum value of centrifugal sll1) 1 Rc coincides with the direction of motion of the snow blower (arrow V in Fig. 3).

When the shaft 23 rotates in the SV sector, the centrifugal force Rc decomposes the two component forces PO and PT. At the same time, the force Ро presses the snowplow to the ground, and the force of the PT Strem ts to move the snowplow along the arrow V, the force of friction increases. As the load approaches the point B, the RT force increases, and the PO force decreases, and at point B, these forces take on the value of RT Hz.In the BA sector, the RO force tends to lift the front part of the snow blower (the friction force decreases), and the RT force continues to act as a driving force. force decreasing to zero at point A. In the sectors AD and DC, the horizontal component tends to move the device in the opposite direction, but it is minimal in magnitude, since the radius of rotation is the smallest, and when the worker attaches the rear of the bottom of the case to the reverse movement does not occur. The strength of the friction between the rear of the hull and the ground is maximum.

As a result of the decomposition of the force Rc, the device is supplied by jerks (5–2 cm) per one revolution of the shaft 23, and the resulting periodic oscillations of the snowplow body in a vertical plane result in the loosening of the snow layer.

This facilitates its movement and reduces the penetration force, and also contributes to the shedding of the upper layers of snow, which makes it possible to clear snow in a single pass with a depth much larger than the diameter of the rotor.

Feed is improved if the bottom of the snow blower body slides over the ground, and not over the snow. Prev Invention

A snow plow for snow removal in hard-to-reach places, including a body, a rotor and an engine with a shaft, characterized in that, in order to facilitate the movement of the snow blower and reduce the force of the snow plow into the snow massif, holes are formed in the shaft body, in which radial moving the fingers, on the free ends of which the weights are fixed, and the body is made with an internal cylindrical surface located eccentrically to the shaft and enclosing the fingers with weights.
