Description
- This application claims the benefit of U.S. Provisional Application No. 61/987,749 filed May 2, 2014.
- The subject invention relates to a snow removal apparatus. Snow removal is a time consuming, labor intensive, and equipment intensive process. Accordingly, snow removal is a very expensive endeavor for communities of all sizes and populations, especially in areas where space to pile and store the snow off the roadway is limited, such as in downtown areas, roadways with adjacent barricades, and airport settings where there is not much space to pile up the snow.
- Traditional methods of snow removal from areas where space is limited including plowing newly fallen snow into rows. The rows of snow are then either plowed to the side of the road or delivered to a dump site via graders, front-end loaders and dump trucks. This process is very time consuming, inefficient, and costly. Additionally, the snow removal vehicles may have to maneuver in relatively confined areas, which in turn requires a smaller sized and less efficient snow removal equipment. Further, in the case of on-site snow storage, the collected snow often consumes needed space, such as parking spots or storage areas.
- Therefore, there exists a need for a snow removal system that is maneuverable, eliminates the need for on-site snow storage, efficiently heats and melts the collected snow, and meets or exceeds the performance requirements of the end user.
- A snow removal apparatus is presented having a snow collection system that includes a housing having an auger and an impeller. The snow collection system feeds collected snow to a main duct which feeds the collected snow to the hollow interior of a tank. The tank includes at least one baffle therein and a heating system which rapidly converts the frozen snow into liquid and steam. The steam generated within the tank is vented through an exhaust opening into the atmosphere. By converting snow to steam the snow removal apparatus presented increases the speed and ease of snow removal and elevates many of the disadvantages of conventional snow removal such as snow transportation and storage.
- Other advantages of the invention will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
-
FIG. 1 is a perspective view of a snow removal apparatus attached to a vehicle; -
FIG. 2 is a top view of the snow removal apparatus attached to a vehicle; -
FIG. 3 is a cross-sectional view of a front thrower of the snow removal apparatus; -
FIG. 4 is a front view of the snow removal apparatus attached to a vehicle; -
FIG. 5 is a rear view of the snow removal apparatus attached to a vehicle; and -
FIG. 6 is schematic cross-sectional view of a tank of the snow removal apparatus. - Referring to the Figures, wherein like numerals indicate like or corresponding parts throughout the several views, a
snow removal apparatus 10 is generally shown inFIG. 1 . Thesnow removal apparatus 10 is designed to collect snow disposed upon a ground surface, such as a road or parking lot. Once the snow is collected, it can be melted into water and/or heated into steam for subsequent removal from thesnow removal apparatus 10. - Once melted, the collected snow occupies only a fraction of the volume of the collected snow. Additionally, the discharge of the water and/or steam can be a continuous process thereby limiting the amount of collected snow and/or water that must be stored within the
snow removal apparatus 10. For example, the water may be disposed of by discharge it into a catch basin, tanker, reclamation system, or the ground surface outside the limits of the roadway. Additionally, the collected snow can quickly be sublimated into steam and released from thesnow removal apparatus 10. - With reference to
FIGS. 1-6 , thesnow removal apparatus 10 includes asnow collection system 12, a heating system 14, and atank 16. Generally, thetank 16 houses a portion of the heating system 14. Further, thetank 16 stores the collected snow as it is melted. Thesnow collection system 12 collects the snow from the ground surface and deposits the collected snow into thetank 16. The heating system 14 heats and maintains the temperature within thetank 16 for quickly converting the collected snow into water and/or steam. - With reference to
FIGS. 1-5 , thetank 16 is in communication with thesnow collection system 12 such that thesnow collection system 12 delivers the snow to thetank 16. Thesnow collection system 12 will be described in detail below. As illustrated in the Figures, thetank 16 is adapted to be coupled to a vehicle, such as a truck. However, it should be apparent to those skilled in the art that thetank 16 may be adapted to be a stationary object, wherein the collected snow is deposited into thetank 16 by a separate device, such as a front end loader or a dump truck (not shown). Further still, it should be apparent to those skilled in the art that thesnow collection system 12 may be separated from thetank 16 such that thetank 16 is disposed upon a first vehicle or trailer and thesnow collection system 12 is disposed upon a second vehicle that either tows the first vehicle or trailer or operates in proximity to the first vehicle or trailer, discharging collected snow into thetank 16. - The
tank 16 may be formed from any rigid material, such as steel. Thetank 16 is typically bolted onto a base that consists of multiple metal beams that are contoured to the proper shape to support thetank 16. For extra stability, bracers may be placed between each beam as well. - The
tank 16 may be a rectangular hollow block structure having four side walls, a bottom surface, and a top surface. Although thetank 16 is depicted and described as being a hollow block structure, it should be apparent that thetank 16 may be formed in any suitable manner, such as to have a rounded cross-section. - As best shown in
FIG. 6 , thetank 16 defines astorage chamber 18 configured to store the collected snow, water, and/or steam. Thetank 16 includes at least one baffle assembly 20 extending outward toward the side walls of thetank 16. The baffle assembly 20 reduces a free surface effect of the water and/or collected snow contained in thestorage chamber 18, especially during braking and accelerating operations by the vehicle. It should be appreciated that thetank 16 can include any suitable number of baffle assembles 20. - The baffle assembly 20 includes at least one
vent hole 22 near a top of the baffle assembly 20 for allowing passage of steam from one portion of thestorage chamber 18 to another portion of thestorage chamber 18 separated by the baffle assembly 20. Likewise, the baffle assembly 20 includes at least onefluid hole 24 near a bottom of the baffle assembly 20 for allowing a specific passage rate of water from one portion of thestorage chamber 18 to another portion of thestorage chamber 18 separated by the baffle assembly 20. - As alluded to above, the
snow collection system 12 is in communication with thetank 16 for transporting snow from the ground surface into thestorage chamber 18 of thetank 16. With reference toFIGS. 1-4 , thesnow collection system 12 includes afront thrower assembly 26, which comprises ahousing 28 surrounding at least oneauger 30. More typically, thefront thrower 26 includes threeaugers 30. Typically, when thesnow removal apparatus 10 is attached to the vehicle, theaugers 30 are 16-inches in diameter and 120-inches wide. However, it is to be appreciated that theaugers 30 can be of any suitable size required based on the size and application of the snow removal system. Additionally, theaugers 30 may be heated to minimize a buildup of snow and ice on theaugers 30, which could slow or stop the collection of snow. - In the illustrated embodiment, the
front thrower 26 includes afirst auger 30A and asecond auger 30B arranged adjacent to each other. Additionally, as best shown inFIGS. 3 and 4 , a fan orimpeller 32 is located downstream from theaugers 30 to assist with the transportation of the collected snow into thestorage chamber 18 of thetank 16. As the snow travels through theaugers 30 and theimpeller 32, it is chopped into fine particles that can be heated and sublimated fairly quickly once inside thestorage chamber 18. - The
snow collection system 12 may include amain duct 34 disposed between theaugers 30 and thetank 16 for directing the collected snow from theaugers 30 to thestorage chamber 18 of thetank 16. Themain duct 34 has a first end coupled to thehousing 28 of thefront thrower 26 and a second end directed to discharge into thestorage chamber 18. Theimpeller 32 is located at the first end of themain duct 34 opposite thetank 16. Theimpeller 32 imparts a selected velocity to the snow chopped by theaugers 30 and directs the snow through themain duct 34. It is to be appreciated that themain duct 34 may be heated for preventing the buildup of snow and ice within themain duct 34 as well as assisting with the conversion of the collected snow into water and/or steam. - The
augers 30 andimpeller 32 of thesnow collection system 12 can be powered by any suitable means. For example, thesnow collection system 12 may be powered by a well-known Power Take-Off (PTO) device which would couple an engine of the vehicle to thesnow collection system 12 to power thesnow collection system 12. - Although the illustrated embodiment depicts the
main duct 34 for directing the collected snow from thehousing 28 of thefront thrower 26 to thestorage chamber 18, it should be appreciated that alternate snow conveyance means may be employed, such as a conveyor belt. - With reference to
FIG. 6 , the heating system 14 is at least partially disposed within thestorage chamber 18 of thetank 16. The heating system 14 includes cables and/or tubing 36 for conducting an electrical current to generate heat within thestorage chamber 18 of thetank 16. The tubing 36 is coil wound to an interior of thetank 16 such that the tubing 36 lines the interior of thetank 16. - The tubing 36 may contain a wire disposed therein for conducting the electrical current. The wire may be a nichrome 80/20 wire, which has relatively high resistance and forms a layer of chromium oxide when heated for the first time. However, any suitable wire and/or tubing 36 may be used to quickly obtain and maintain the proper temperature within the
storage chamber 18. Additionally, the oxidation prevents the wire from breaking and/or burning out. The tubing 36 may include a layer of ceramic electrical insulation coving the wire with a metal sheath covering both the insulation and the wire. The metal sheath may comprise copper, which has a melting point of about 1,984 degrees Fahrenheit (1,085 degrees Celsius). - The heating system 14 may include a layer of insulation within the
tank 16 between the tubing 36 and the interior of thetank 16. The insulation between the tubing 36 and the inside of thetank 16 prevents outside cold air from leaking in thestorage chamber 18 thereby cooling the temperature of thestorage chamber 18. Additionally, the insulation prevents the outside of the tank from become too hot. - In addition to the tubing 36, the heating system 14 may utilize the exhaust of the vehicle to heat and or maintain the temperature within the
storage chamber 18 at the proper temperature. As such, the tank defines anengine exhaust inlet 38 for allowing the exhaust from the engine to enter thestorage chamber 18. - The electrical current is provided to the tubing 36 by a battery system. The battery system can be recharged in any suitable manner. For example, the battery system can be coupled to the engine of the vehicle such that the engine of the vehicle recharges the battery system. Additionally, the battery system may include an independent engine specifically dedicated to the recharging of the battery system. Furthermore, the battery system may be recharged by regenerative systems which convert output energy into stored energy within the battery system. For example, the vehicle may include a regenerative braking system for converting braking energy into stored energy within the battery system. Additionally, rotation of a secondary free axle on the vehicle may also be utilized to recharge the battery system.
- The heating system 14 is controlled by a heating control device with easily accessible emergency shutoff will be located in the cab for the operator.
- When the
tank 16 reaches proper temperature, which can be observed by the operator from the cab, thesnow removal apparatus 10 will then be capable of converting snow into steam. Once the proper temperature is reached, any snow or water within thestorage chamber 18 will be converted to steam and will travel to anexhaust opening 40 defined by thetank 16 where the steam is discharged from thetank 16. It is to be appreciated that the exhaust opening may include a pressure valve 42 for selectively allowing passage of the steam from thestorage chamber 18 into the atmosphere once a predetermined pressure is reached within thestorage chamber 18. The pressure valve 42 also minimizes heat loss during operation of the heating system 14. - It is to be appreciated that the steam may be used to power the engine of the vehicle any/or to recharge the battery system of the vehicle in an effort to increase an overall efficiency of the vehicle.
- It is to be appreciated that the process of converting the collected snow into water and/or steam may include spraying the collected snow with water. The water sprayed onto the collected snow may be heated to further assist with the conversion of the collected snow into water and/or steam. Additionally, the process of converting the collected snow into water and/or steam may include the application of heated air directed at the collected snow rather than just maintaining the temperature within the
tank 16. - In operation, as the
snow removal apparatus 10 moves forward, thefront thrower 26 scoops up snow from the ground surface and directs the snow into theaugers 30. Theaugers 30 pulverize the snow and direct the pulverized snow into theimpeller 32. Theimpeller 32 imparts a high velocity to the collected snow for forcing the snow through themain duct 34 and into thestorage chamber 18 of thetank 16. - As the snow is discharged into the
tank 16, the snow is rapidly heated to convert the snow from a solid to a liquid and eventually to a gas. The steam is then discharged from thetank 16 through theexhaust opening 40. Thetank 16 may include a drain port for removing any water collected within thestorage chamber 18 of thetank 16. It is to be appreciated that during normal operation of thesnow removal apparatus 10, the drain port is not utilized because the water within thestorage chamber 18 is converted to steam. However, the drain port allows for maintenance and the release of any condensation that may build within thestorage chamber 18 during transportation of thesnow removal apparatus 10. - In addition to surrounding the
augers 30, thehousing 28 may also be designed to ride along the ground surface for clearing the ground surface of snow. However, it is understood that due to the often uneven surface of the ground surface, thehousing 28 may not be capable of collecting and removing all of the snow from the ground surface. As such, as shown inFIGS. 1 and 3 , thesnow removal apparatus 10 may include at least onebrush 41 for sweeping the ground surface clear. Additionally, thesnow removal apparatus 10 may include aground heater 43 configured to directed heated air toward the ground surface. The heated air may be obtained from thestorage chamber 18 of thetank 16 and/or from the exhaust of the motor driving the vehicle and/or theaugers 30. - While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
- Alternative Arrangement: While the
snow removal apparatus 10 is shown and described herein primarily as a self-powered and full-sized vehicle, such as a conventional truck, it is hereby contemplated that thesnow removal apparatus 10 can take on any shape or form. That is, it is hereby contemplated that hesnow removal apparatus 10 is small enough to be operated by hand, such as being sized and shaped similar to conventional snow blowers.
