Description

Technical Field

[0001] The utility model relates to the technical field of snow machines, and particularly relates to a spiral knife device for a snow machine. Background Art

[0002] A snow machine is a common snow scene simulator. It creates a beautiful and romantic winter atmosphere for people by simulating the process of snowflakes falling in nature. During the snow-making process of the snow machine, water is first made into small ice particles, and then the ice particles are broken by a spiral knife device to make the ice smaller. In some spiral knife devices, a set of spiral cutters are arranged inside the housing of the device. The spiral cutters are driven by a driving element to rotate and break the ice inside the snow machine. First, the ice drops vertically downward along the middle of the device housing. The driving element drives the spiral cutters to rotate. During the rotation of the spiral cutters, the ice is broken by the shearing force generated by the high-speed horizontal rotation of the cutters themselves. However, the running direction of the spiral cutters inside the device is single, and the direction of the ice-breaking shearing force generated remains unchanged, resulting in limited ice-breaking effect on the ice inside the snow machine. For this reason, we propose a spiral knife device for a snow machine. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a spiral knife device for a snow machine. Through a transmission element, the device makes the directions of the horizontal ice-breaking shearing forces generated by two groups of spiral cutters inside the device opposite, thereby improving the ice-breaking effect of the device on the ice inside the snow machine. At the same time, the device changes the ice-breaking movement path of the ice, further improving the ice-breaking effect of the device on the ice inside the snow machine, and can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A spiral knife device for a snow machine, comprising a housing and a crushing mechanism;

[0005] Housing: Its conical top wall is penetrated by a feed pipe;

[0006] Crushing mechanism: It includes fixed rods, a partition shell, hollow spiral cutters, a first rotating shaft and solid spiral cutters. There are four fixed rods, and the four fixed rods are evenly arranged at the upper end of the inner wall of the housing. A partition shell is arranged between the four fixed rods. The bottom wall of the partition shell is rotationally connected to a hollow spiral cutter through a first bearing. The inside of the hollow spiral cutter is rotationally connected to a first rotating shaft through a second bearing. A solid spiral cutter is arranged at the lower end of the first rotating shaft. Through a transmission element, the device makes the directions of the horizontal ice-breaking shearing forces generated by two groups of spiral cutters inside the device opposite, thereby improving the ice-breaking effect of the device on the ice inside the snow machine. At the same time, the device changes the ice-breaking movement path of the ice, further improving the ice-breaking effect of the device on the ice inside the snow machine.

[0007] Further, it further includes a control switch which is located outside the housing. The input end of the control switch is electrically connected to an external power supply, facilitating the control of electrical components.

[0008] Further, the crushing mechanism further includes an end face gear, a second rotating shaft, and a spur gear. The second rotating shaft is rotatably connected between the partition housing and the housing through a third bearing. A spur gear is provided at the left end of the second rotating shaft. End face gears are provided at the upper outer side of the hollow spiral cutting tool and the upper end of the first rotating shaft, and the end face gears are meshed with the spur gear, making the horizontal crushing shear force directions of the ice cubes generated by the two sets of spiral cutting tools in the device opposite.

[0009] Further, a driving motor is provided on the outer side of the housing. The input end of the driving motor is electrically connected to the output end of the control switch, and the output shaft of the driving motor is fixedly connected to the right end of the second rotating shaft, providing power for the device to crush the ice cubes in the snow blower.

[0010] Further, a ring-shaped convex plate is provided on the conical top wall of the housing through four uniformly distributed connecting rods. A plurality of uniformly distributed through holes are provided inside the ring-shaped convex plate, making the ice cubes distributed horizontally in a dispersed manner during the vertical falling process, avoiding insufficient crushing effect of the device on the ice cubes due to the vertical falling of the aggregated ice cubes.

[0011] Further, four uniformly distributed inclined plane annular seats are provided on the inner wall of the housing, making the ice cubes falling from the edge part inside the snow blower spiral knife device move towards the center part of the device under the action of the inclined collision component force, thereby improving the crushing effect of the device on the ice cubes.

[0012] Further, an installation ring is provided at the lower outer side of the housing, facilitating the installation of the snow blower spiral knife device to a specified position inside the snow blower through bolts.

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , this embodiment provides a technical solution: a snow machine spiral knife device, including an outer shell 1 and a crushing mechanism 4;

[0022] Outer shell 1: Its conical top wall is penetrated by a feed pipe 3. The conical top wall of the outer shell 1 is provided with an annular convex plate 7 through four evenly distributed connecting rods 6. A plurality of evenly distributed through holes are formed inside the annular convex plate 7. The inner wall of the outer shell 1 is provided with four evenly distributed inclined surface annular seats 8. The lower end of the outer side of the outer shell 1 is provided with a mounting ring 9. When using the snowflake-making machine spiral knife device, first, the device is fixed to the corresponding position inside the snowflake-making machine through the mounting holes on the mounting ring 9 with bolts. The ice cubes generated during the water snow-making process inside the snowflake-making machine enter the device through the feed pipe 3. The ice cubes in the feed pipe 3 fall above the annular convex plate 7. The ice cubes slide along the upper arc surface of the annular convex plate 7 from the middle to the periphery. When the ice cubes pass through the through holes on the annular convex plate 7, the ice cubes pass through the corresponding through holes and fall vertically downward. Through the design of the through holes and the arc surface of the annular convex plate 7, the ice cubes falling from the upper part inside the device fall vertically downward in a horizontally dispersed state, avoiding the ice cubes gathering together during the falling process and affecting the crushing effect of the spiral cutter on them. Through the inclined surface design of the inclined surface annular seat 8, the ice cubes falling on the inner edge part of the device impact on the inclined surface of the inclined surface annular seat 8. Through the horizontal component force generated by the collision between the ice cubes and the inclined surface of the inclined surface annular seat 8, the ice cubes on the inner edge part of the device then move towards the central part inside the device, thereby improving the crushing effect of the spiral cutter on the ice cubes. This device improves the crushing effect of the device on the ice cubes inside the snowflake-making machine by changing the crushing and moving path of the ice cubes;

[0023] Crushing mechanism 4: It includes a fixed rod 41, a partition shell 42, a hollow spiral cutter 43, a first rotating shaft 44 and a solid spiral cutter 45. There are four fixed rods 41, and the four fixed rods 41 are evenly arranged at the upper end of the inner wall of the outer shell 1. A partition shell 42 is arranged between the four fixed rods 41. The bottom wall of the partition shell 42 is rotatably connected to the hollow spiral cutter 43 through a first bearing. The inner part of the hollow spiral cutter 43 is rotatably connected to the first rotating shaft 44 through a second bearing. A solid spiral cutter 45 is arranged at the lower end of the first rotating shaft 44. It also includes a control switch 2, and the control switch 2 is located outside the outer shell 1. The input end of the control switch 2 is electrically connected to an external power supply. The crushing mechanism 4 further includes an end face gear 46, a second rotating shaft 47 and a spur gear 48. The second rotating shaft 47 is rotatably connected between the partition shell 42 and the outer shell 1 through a third bearing. A spur gear 48 is arranged at the left end of the second rotating shaft 47. End face gears 46 are arranged at the upper outer side of the hollow spiral cutter 43 and the upper end of the first rotating shaft 44. The end face gears 46 are all meshed with the spur gear 48. A driving motor 5 is arranged outside the outer shell 1. The input end of the driving motor 5 is electrically connected to the output end of the control switch 2. The output shaft of the driving motor 5 is fixedly connected to the right end of the second rotating shaft 47. During the process of the ice block moving vertically downward inside the device, the control switch 2 starts the driving motor 5 to make its output shaft drive the second rotating shaft 47 to rotate. The second rotating shaft 47 drives the spur gear 48 to rotate forward. The spur gear 48 drives the hollow spiral cutter 43 to rotate forward through meshing with the lower end face gear 46. The spur gear 48 drives the first rotating shaft 44 to drive the lower solid spiral cutter 45 to rotate reversely through meshing with the upper end face gear 46. The hollow spiral cutter 43 rotates forward and the solid spiral cutter 45 rotates reversely. The two groups of spiral cutters inside the device apply horizontal rotary shearing and crushing forces in opposite directions to the vertically falling ice blocks, thereby improving the crushing effect of the device on the ice blocks in the snow blower.

[0024] The working principle of a snowflake machine spiral knife device provided by the utility model is as follows: When using the snowflake machine spiral knife device, first fix the device to the corresponding position inside the snowflake machine through the mounting holes on the mounting ring 9 with bolts. During the snow-making process of the water body inside the snowflake machine, the ice cubes generated enter the device through the feed pipe 3. During the vertical downward movement of the ice cubes along the inside of the device, the control switch 2 starts the driving motor 5, and its output shaft drives the second rotating shaft 47 to rotate. The second rotating shaft 47 drives the spur gear 48 to rotate forward. The spur gear 48 is meshed and connected with the end face gear 46 on the lower side, thereby driving the hollow spiral cutting knife 43 to rotate forward. The spur gear 48 is meshed and connected with the end face gear 46 on the upper side, so that the first rotating shaft 44 drives the solid spiral cutting knife 45 on the lower side to rotate in the reverse direction. The hollow spiral cutting knife 43 rotates forward and the solid spiral cutting knife 45 rotates in reverse. The two groups of spiral cutting tools inside the device apply horizontal rotating shear breaking forces in opposite directions to the vertically falling ice cubes, thereby improving the breaking effect of the device on the ice cubes inside the snowflake machine. The ice cubes in the feed pipe 3 fall above the annular convex plate 7, and the ice cubes slide and spread from the middle to the surroundings along the upper arc surface of the annular convex plate 7. When the ice cubes pass through the through holes on the annular convex plate 7, the ice cubes pass through the corresponding through holes and fall vertically downward. Through the design of the through holes and the arc surface of the annular convex plate 7, the ice cubes falling from above inside the device fall vertically in a horizontally dispersed state, avoiding the ice cubes gathering together during the falling process and affecting the breaking effect generated by the spiral cutting tools on them. Through the inclined surface design of the inclined surface annular seat 8, the ice cubes falling from the inner edge part of the device impact on the inclined surface of the inclined surface annular seat 8. Through the horizontal component force generated by the collision between the ice cubes and the inclined surface of the inclined surface annular seat 8, the ice cubes at the inner edge part of the device then move towards the central part inside the device, thereby improving the breaking effect of the spiral cutting tools on the ice cubes.

[0025] It should be noted that the driving motor 5 disclosed in the above embodiments can adopt Y80M1-2, and the control switch 2 is provided with a control button corresponding to the driving motor 5 for controlling its switch.

[0026] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
