Description

Technical Field

[0001] This invention relates to the field of de-icing devices, and more specifically, to a de-icing machine. Background Technology

[0002] A de-icing machine is a device used to remove ice from the surface of objects, such as roads and glass surfaces. Currently, Chinese Patent Publication No. CN221851877U discloses a de-icing disc and a de-icing machine. In this de-icing machine structure, the de-icing machine adopts a single blade disc structure. As the blade disc rotates relative to the object surface during the de-icing process, it is easy for the blade disc and the de-icing machine to slip sideways. This not only affects the efficiency and effect of the blade disc in removing ice from the object surface, but also poses a significant safety hazard, as it can easily cause injury when the de-icing machine slips sideways. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a de-icing machine that, by setting two cutter disc assemblies, can prevent the de-icing machine from slipping when the two cutter disc assemblies are simultaneously de-icing the surface of an object.

[0004] This invention provides a de-icing machine, including a main unit, a handle connector, and two blade assemblies. The handle connector is installed on the upper end of the main unit and is used to connect to a handle. The main unit has two output shafts, both of which are connected to a motor located inside the main unit. The lower ends of both output shafts extend out of the main unit from the bottom. The two blade assemblies are respectively connected to the lower end of one of the output shafts. When the motor drives the two blade assemblies to rotate via the two output shafts, the two blade assemblies are used to de-ice objects, and the two blade assemblies rotate in opposite directions.

[0005] This invention employs two cutter disc assemblies rotating in opposite directions. When both assemblies simultaneously de-ice an object's surface, the lateral sliding forces generated when they contact the ice surface cancel each other out. This prevents the de-icing machine from slipping on the ice, ensuring reliable de-icing operations and maximizing the efficiency and effectiveness of ice removal. Furthermore, it eliminates the safety hazard of injury caused by the de-icing machine by preventing lateral slippage.

[0006] In one possible implementation, the main unit includes a housing; a handle connector is installed at the upper end of the housing; a motor is fixed inside the housing; two output shafts are spaced apart to the left and right; the upper ends of both output shafts extend into the housing and are rotatably connected to the housing via bearing sets; the two output shafts are connected to the motor shaft via a gear set located inside the housing; and when the motor drives the two output shafts to rotate via the gear set, the two output shafts rotate in opposite directions; the lower ends of both output shafts extend out of the housing through the bottom of the housing.

[0007] In one possible implementation, a transmission component is coaxially fixed to the lower end of each output shaft, and each cutter disc assembly includes a turntable and a cutter disc; the upper end of each turntable is detachably connected to the transmission component at the corresponding position, and each cutter disc is detachably connected to the lower end of the corresponding turntable; and several scrapers evenly distributed circumferentially are provided at the edge of the lower end of each cutter disc.

[0008] In one possible implementation, each output shaft has a screw with an outer diameter smaller than the output shaft coaxially mounted at its lower end. Each transmission component has a hexagonal recess with an open lower end in its middle, and a nut is embedded in each recess. The transmission component above the recess has a vertical shaft hole, through which the screw passes and is threadedly fastened to the nut. The upper end of each transmission component is tightly abutted against the lower end of the corresponding output shaft. The rotation direction of each output shaft driving the transmission component is opposite to the threaded fastening direction of the corresponding screw and nut.

[0009] In one possible implementation, the transmission component has a slot with an open lower end. Two locking holes are provided on two opposite sides of the slot. Two spring-loaded latches are symmetrically arranged at the center of the upper end of the turntable. These two spring-loaded latches are inserted into the slot and engage with the two locking holes. Two inserting pieces are symmetrically arranged at the upper end of the turntable. These two inserting pieces are inserted into the slot and abut against the inner walls of the other two opposite sides of the slot. A sleeve is also coaxially arranged at the upper end of the turntable. The sleeve is fitted onto the outside of the transmission component. Two limiting grooves are symmetrically arranged on the inner wall of the sleeve. Two limiting ribs are symmetrically arranged on the outer wall of the transmission component. Each limiting rib vertically engages with the corresponding limiting groove to circumferentially limit the movement of the turntable and the transmission component.

[0010] In one possible implementation, a plurality of circumferentially evenly distributed Velcro fasteners are fixed on the lower end face of the turntable, and a plurality of circumferentially evenly distributed Velcro female fasteners are fixed on the upper end face of the cutter head.

[0013] In one possible implementation, the scraper and the blade disc are integrally injection molded from plastic material.

[0014] In one possible implementation, the de-icing machine further includes a protective cover; the inner wall of the protective cover is provided with an annular protrusion, the lower end of the main unit is inserted into the upper end of the protective cover and abuts against the annular protrusion, and the protective cover is fastened by screws that pass through the annular protrusion and are threadedly connected to the main unit; the lower part of the protective cover covers the outside of the two cutter disc assemblies, and the lower ends of the two cutter disc assemblies are exposed outside the protective cover.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] See Figures 1-9 As shown in the figure, this application discloses a de-icing machine, including a main unit 1, a handle connector 2, and two blade assemblies. The handle connector 2 is installed on the upper end of the main unit 1 and is used to connect to the handle. The main unit 1 has two output shafts 3, both of which are connected to a motor 4 located inside the main unit 1. The lower ends of both output shafts 3 extend out of the main unit 1 through the bottom of the main unit 1. The two blade assemblies are respectively connected to the lower end of one of the output shafts 3. When the motor 4 drives the two blade assemblies to rotate through the two output shafts 3, the two blade assemblies are used to de-ice objects, and the rotation directions of the two blade assemblies are opposite.

[0021] The main unit 1 includes a housing 11; a handle connector 2 is installed on the upper end of the housing 11; a motor 4 is fixed inside the housing 11; two output shafts 3 are spaced apart to the left and right, with the upper ends of both output shafts 3 extending into the housing 11 and rotatably connected to the housing 11 via a bearing assembly 31; the two output shafts 3 are connected to the rotating shaft of the motor 4 via a gear set located inside the housing 11, and when the motor 4 drives the two output shafts 3 to rotate via the gear set, the rotation directions of the two output shafts 3 are opposite; the lower ends of both output shafts 3 extend out of the housing 11 through the bottom of the housing 11; by adopting this main unit structure, in the bearing assembly Under the action of the motor, both output shafts can be reliably connected to the housing. When the motor shaft rotates, the motor can reliably drive the two output shafts to rotate via the gear set. The two output shafts rotate in opposite directions, which in turn drives the two cutter disc assemblies to rotate in opposite directions. Since the two cutter disc assemblies rotate in opposite directions, when the two cutter disc assemblies simultaneously de-ice the surface of an object, the lateral slipping force generated when the rotating cutter disc assemblies come into contact with the ice surface can cancel each other out. This prevents the de-icing machine from slipping on the ice surface, thus enabling the two cutter disc assemblies to reliably perform de-icing operations.

[0022] Each output shaft 3 has a transmission component 5 coaxially fixed at its lower end. Each cutter disc assembly includes a turntable 6 and a cutter disc 7. The upper end of each turntable 6 is detachably connected to the transmission component 5 at the corresponding position, and each cutter disc 7 is detachably connected to the lower end of the corresponding turntable 6. Several scrapers 71 are evenly distributed circumferentially at the lower edge of each cutter disc 7. With this structure, after the turntable is connected to the transmission component and the cutter disc is connected to the turntable, the output shaft can reliably drive the cutter disc to rotate so that the scrapers on the cutter disc can remove ice from the object. Because the turntable is detachably connected to the transmission component and the cutter disc is detachably connected to the turntable, the turntable and / or cutter disc can be easily replaced when the turntable and / or cutter disc ages.

[0023] Each output shaft 3 has a screw 32 with an outer diameter smaller than that of the output shaft 3 coaxially mounted at its lower end. Each transmission component 5 has a hexagonal recess 51 with an open lower end in its middle. A nut 33 is embedded in each recess 51. A shaft hole 52 is vertically mounted in the transmission component 5 above the recess 51. The screw 32 passes through the shaft hole 52 and is threadedly fastened to the nut 33. The upper end of each transmission component 5 is tightly abutted against the lower end of the corresponding output shaft 3. The rotation direction of each output shaft 3 driving the transmission component 5 is opposite to the threaded fastening direction of the corresponding screw 32 and nut 33. By adopting this... After the structure is completed, once the screw passes through the shaft hole and is threadedly fastened to the nut, the transmission component can be reliably fastened to the output shaft. That is, the transmission component can be reliably pressed between the nut and the output shaft. In addition, since the rotation direction of each output shaft 3 driving the transmission component 5 is opposite to the threaded fastening direction of the corresponding screw 32 and nut 33, the nut and screw can be effectively prevented from loosening when the output shaft drives the transmission component, turntable and cutter head to rotate. That is, the transmission component can be effectively prevented from loosening from the output shaft, so as to ensure that the output shaft reliably drives the transmission component, turntable and cutter head to rotate.

[0024] The transmission component 5 is provided with a slot 53 with an open lower end. Each of the two opposite sides of the slot 53 has a locking hole 54. Two spring clips 61 are symmetrically arranged at the center of the upper end of the turntable 6. The two spring clips 61 are inserted into the slot 53 and engage with the two locking holes 54. Two insert pieces 62 are symmetrically arranged at the upper end of the turntable 6. The two insert pieces 62 are inserted into the slot 53 and abut against the inner walls of the other two opposite sides of the slot 53. A sleeve 63 is also coaxially arranged at the upper end of the turntable 6. The sleeve 63 is fitted onto the outside of the transmission component 5. Two limiting grooves 64 are symmetrically arranged on the inner wall of the sleeve 63. Two limiting ribs 55 are symmetrically arranged on the outer wall of the transmission component 5. Each limiting rib 55 vertically engages with the corresponding limiting groove 64 to... The turntable 6 and the transmission component 5 are circumferentially limited. With this structure, when the turntable and the transmission component are connected, the two plug-in pieces and the slots are engaged, and the two plug-in pieces abut against the inner walls of the other two opposite sides of the slots. This can limit and guide the assembly of the turntable and the transmission component. After the two spring clips are inserted into the slots and engaged with the two locking holes, the turntable can be reliably connected to the transmission component. In addition, after the sleeve is sleeved with the transmission component, each limiting rib can be vertically engaged with the corresponding limiting groove. This allows the turntable to be reliably circumferentially limited between itself and the transmission component, so that the transmission component can reliably drive the turntable to rotate. Furthermore, the above connection method has the advantage of easy assembly and disassembly of the turntable and the transmission component.

[0025] Several circumferentially evenly distributed Velcro fasteners 81 are fixed on the lower end surface of the turntable 6, and several circumferentially evenly distributed Velcro female fasteners 82 are fixed on the upper end surface of the cutter head 7. Each Velcro fastener 81 is attached to a corresponding Velcro fastener 82 to connect the cutter head 7 to the turntable 6. With this structure, the cutter head can be reliably and conveniently connected to the turntable through the Velcro female fasteners and Velcro fasteners, and has the advantage of easy cutter head replacement. In addition, the above-mentioned Velcro fasteners and Velcro female fasteners can also be interchanged.

[0026] Two limiting blocks 72 are symmetrically arranged in the middle of the upper end face of the cutter head 7, and two limiting holes 65 are symmetrically arranged in the middle of the turntable 6. Each limiting block 72 is inserted into the limiting hole 65 at the corresponding position. With this structure, after the cutter head and the turntable are assembled, each limiting block can be inserted into the limiting hole at the corresponding position, so that the cutter head can reliably achieve circumferential limiting with the turntable, that is, the turntable can reliably drive the cutter head to rotate.

[0027] Each scraper 71 is bent from the inside out in the direction of rotation of the blade disk 7 along the radial direction of the blade disk 7 to form a blade edge 711. The lower end face of each scraper 71 is gradually inclined upward from the inside out to form a curved surface 712. By adopting this structure, each scraper can be made sharper, which makes it easier for the scraper to remove ice from the object and ensures the de-icing efficiency.

[0028] The scraper 71 and the blade disc 7 are integrally injection molded from plastic material. By using plastic material to make the scraper and blade disc, damage to the object can be effectively avoided when the scraper removes ice from the surface of the object. For example, when scraping ice from the surface of glass, the scraper can effectively avoid damaging or scratching the glass. In addition, since the scraper and blade disc are integrally injection molded from plastic material, they have the advantages of high connection strength and good overall integrity.

[0029] The de-icing machine also includes a protective cover 9; the inner wall of the protective cover 9 is provided with an annular protrusion 91, the lower end of the main unit 1 is inserted into the upper end of the protective cover 9 and abuts against the annular protrusion 91, and the protective cover 9 is fastened by screws that pass through the annular protrusion 91 and are threadedly connected to the main unit 1; the lower part of the protective cover 9 covers the outside of the two cutter disc assemblies, and the lower ends of the two cutter disc assemblies are exposed outside the protective cover 9; by setting the protective cover, when the user uses the de-icing machine, the human body can be avoided from contacting the rotating cutter disc assembly as much as possible, thereby improving the safety of the de-icing machine during use; in addition, by adopting the above-mentioned fixing structure, the protective cover can be reliably fastened to the main unit.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
