Description

SPARKLING PACK 105352

The present invention relates to a centrifugal package for fastening in front of a vehicle moving it by means of a quick coupler 5 comprising a pair of centrifugal units having one or more centrifuges and a motor with auxiliary means and a power take-off , rotor housing, and directional spouts for centrifuging material.

To achieve high spin rates, spin combinations are known which have a motor in both the spin pack and the vehicle that moves the spin pack. The largest spinners are used especially in 15 airports and other areas where very large amounts of snow must be removed as quickly as possible. These so-called aggregate centrifuges have an internal combustion engine with transmissions, a fuel tank and auxiliary devices fitted to the centrifuge as an independent working unit. The aggregate linkage is typically driven by a wheel loader, tractor or car, in front of which the above-mentioned centrifugal pack is secured by means of a quick coupler. Known centrifugal packages utilize one or more rotors, which may be preceded by separate feeders.

• · «: 25 The entire structure of the known aggregate springs is located in front of the attachment point between the vehicle and the centrifuge. In this case, the center of gravity of the spinner is far away from the attachment point and thus · the nearest wheel axle of the vehicle. Such an arrangement * limits the size and power of the snowmobile used in each vehicle weight class. In this case, the centrifugal spreader • · 'may only be part of the lifting capacity of the vehicle's lifting gear.

It is an object of the invention to provide a more versatile centrifugal centrifugal centrifugal centrifugal centrifugal centrifugal centrifugal centrifugal centrifugal centrifugal centrifuge that can be moved by a lighter vehicle. Characteristic features of the present invention will be apparent from the appended claims. By positioning the components, the center of gravity of the centrifugal package is positioned near the axis closest to the centrifugal package of the moving vehicle, thus maximizing the capacity of the vehicle. In addition, the centrifugal package according to the invention achieves good centrifugal efficiency and internal combustion engine efficiency with a reasonable total centrifugal package weight. Also, the serviceability and reliability of the centrifugal pack are improved.

The invention will now be described in detail with reference to the accompanying drawings, in which:

However, no power take-off or other connections are required.

On the other hand, remote control, emergency stop or other devices facilitating work and safety at work of the centrifugal pack 10 require their own connections. The centrifugal package 10 includes the actual centrifuge 14 and its internal combustion engines 15. The main parts of the centrifuge 14 are the 5 rotor housing 16, the rotor and the directional exhaust manifold 17. The internal combustion engine 15 further comprises auxiliary equipment and transmission including reduction gear 18 and corresponding motors are potential sources of power for the centrifuge package 10. In addition, behind the centrifuge 14 are holders 10, to which the fastening device 13 of the vehicle 11 is connected.

According to the invention, the quick coupling device 13 is disposed in the widthwise direction at opposite ends of the centrifugal units 22 forming the pair of centrifugal units and in the driving direction near them. Further, the motor 15 of the centrifugal unit 22 is located entirely on the side of the quick coupling device 13 so that the center of gravity of the centrifuge package is substantially longitudinally aligned with the quick coupling device 13 or toward the vehicle. In this case, the center of gravity of the centrifugal package 10 is substantially behind the centrifuge 14, close to the quick coupler 13. In the example, the center is even on the front axle 21 of the vehicle 10 25 by total weight. On the other hand, the hydraulic wheel supports (not shown) of the auxiliary devices used to lift the centrifugal package 10 from the base may be attached to the centrifuge pack 10.

The centrifugal package 10 of Figure 2 has two motors 15 and four adjacent centrifuges 14. The figure also shows the location of the motors 15 on the sides of the vehicle 11. The centrifuges 14 are further fitted to units of the two centrifuges 14 connected to the quick clamping device 13.

105352 Hereby, a single centrifugal unit 22 comprises two centrifuges 14 and a single internal combustion engine 15. The centrifugal units 22 are substantially identical and function independently. The spinner unit 22 may also have several spinners 14, but more preferably two to four pieces. The spinner units 22 are connected to one another via a joint 23, which allows the spinner pack 10 to adapt to the substrate. The illustrated centrifuge package 10 is further balanced with respect to both the centerline of the vehicle 11 and the axles. In this case, the vehicle 11 maintains its stability even with a maximum weight of 10.

By using more than one motor, the transmission of the centrifugal unit 22 can be accomplished with light standard components. A single-motor four-spin centrifuge transmission would also be considerably larger and at the same time heavier. In addition, the overall efficiency of two engines is better than that of one engine of equivalent power and is easier to control. Independent independently operating centrifugal units 22 may also be used separately. In this case, 20 fewer spare machines are needed, and if one fails, a new one can be replaced. The extension of the two spinner units 22 can also be attached

In order to ensure the passage of snow, the spinner 14 according to the invention is short and its front surface 26 small. By this front surface is meant a passive surface that pushes snow forward. At the same time, the overall length of the entire combination is small. In practice, the rotor housing 16 forming the centrifuge 14 5 is short and the rotor extends almost to the front surface 26 of the centrifuge 14. In this case, the snow immediately enters the rotor blades, accelerating evenly to the throwing speed. The short distance traveled by the snow in the centrifuge 14 also reduces the risk of clogging and power losses. The front surface 26 further includes additional members 27 for guiding the 10 snow to the rotor (Figure 5a). Under particularly difficult conditions, the front surface 26 can be lifted up, leaving a small amount of snow removed (Figure 5b). The remaining snow passing through the rotor housings 16 is next spun, or is collected on the side or in the area between the wheels of the vehicle 11 by a device (not shown) after the spinner 14 15. Instead of the retractable face 26, the face may have a vibration to improve snow travel. One alternative is to divide the front surface into 26 parts and support the parts with rubber pads and vibrate them with hydraulic vibrators. Electrical, mechanical and pneumatic vibrators are also possible. Usually the vibration of the lower parts is sufficient. Friction can also be reduced by introducing into the front surfaces, through a suitable non-clogged perforation or the like, i ·· 'exhaust gas or even hot water. With exhaust, \ .V further improves the efficiency of the motors 15 and the centrifuge ^ · m *. *: 25 snow bites. Compressed air can also be used here. In addition, the structure of the face surface 26 and the rotor housings 16 further improves the crawling of the centrifuge 14 in snow, ice or otherwise difficult to centrifuge snow.

Although the clogging of the centrifuge 14 is practically unlikely *. , the reduction gear 18 of the internal combustion engine 14 also has a reverse gear ....: to. In this case, developing or already developed obstruction can be removed,. by changing the direction of rotation of the rotors. Preferably, the reduction gear is of the so-called marine gear. The gearbox is smaller than other gears and easier to steer. In addition, the gear unit has continuous dental contact and 6 105352 separate clutches are not required as the gear unit includes clutches. The gearbox also avoids sudden torque changes in the transmission when the spinner is started, thereby reducing the strain on the transmission components. The marine gear also has 5 easy-to-connect electronic remote controls. In the example, the transmission line is straight from the motor and aligned with the rotor shafts, which reduces the number of components required. Here, the dividing line 19 is implemented by means of a chain drive, although hydrostatic or pulleys, belts or the like are also possible.

Figure 6 shows the discharge tubes 17 of the centrifugal package 10 according to the invention, at least the inner surfaces of the discharge tubes 17 are coated with plastic. Fully plastic exhaust pipes 17 are also possible.

15 Friction between plastic and snow is known to be low, whereby the plastic coating achieves low snow feed resistance and low probability of blockage. In spinning consumable materials, in addition to plastics, greater wear must be tolerated, which must be taken into account when selecting the material. As shown in Fig. 6 20, the exhaust pipes 17 are laterally on the same line.

! However, the discharge tubes 17 are arranged in a staggered manner such that the most distant in the discharge direction is upward. This arrangement prevents snow jets from mixing with each other. The raising device 28 can

In addition to the curve 30, the upper portion 30 of the ejector tube »· 25 en 17 expands with respect to the ejection direction in the transverse direction. This gives more snow flow * * * V · space when the snow collides with the curve part 30.

The engine and exhaust pipes are remotely controlled by a vehicle 7 105352 equipped with the necessary monitoring and warning devices. In this case, the centrifugal package can be moved by a variety of vehicles, so no special vehicles are needed. The wheels may also be driven and / or steerable, allowing them to be spun without vehicle power. Preferably, the draw driven by a hydraulic motor is mainly used to move the centrifugal pack only in emergencies. In this case, the centrifuge package is remotely controlled, for example, from a passenger car, on foot or even from an air traffic controller. Thanks to the movable control unit, vehicles normally in other use can also be used for spinning. In addition, the centrifugal units can be operated at different capacities, if necessary.
