Description

Technical Field

[0001] This utility model belongs to the field of snow melting machine technology, specifically relating to a snow melting machine with smooth material discharge. Background Technology

[0002] A snow melting machine generally includes a hopper and a discharge cylinder installed on the side of the hopper. A discharge port connects the hopper and the discharge cylinder. An evaporator and a stirring screw are installed inside the hopper. The stirring screw and evaporator work together to produce slush and push it to the discharge port. A discharge port is located at the bottom of the discharge cylinder. A discharge rod is vertically installed inside the discharge cylinder to block the discharge port. A handle is provided on the discharge cylinder; the user operates the handle to open the discharge port, allowing the slush to enter the discharge cylinder and be discharged downwards along the cylinder.

[0003] Therefore, when using a traditional snow melting machine, after the user opens the discharge port, the slush enters the discharge cylinder and falls from the cylinder solely by its own weight, resulting in a slow discharge. The slush will remain inside the discharge cylinder. Since the discharge cylinder is adjacent to the low-temperature hopper, the slush that is not discharged in time will partially melt and "re-freeze" into lumps, resulting in an uneven texture and even hard frozen lumps. Moreover, some slush will freeze directly and remain on the inner wall of the discharge cylinder, causing incomplete discharge. When the user removes the ice collection cup, the slush remaining in the discharge cylinder melts and drips water, causing cleaning trouble for the user. Utility Model Content

[0004] This invention provides a snow melting machine with smooth discharge, solving the problems of slow discharge and residue in existing snow melting machines, which result in an unsmooth texture and troublesome cleaning for users.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a snow melting machine with smooth material discharge, including a hopper and a discharge cylinder installed on the side of the hopper. The hopper and the discharge cylinder are connected by a discharge port. The bottom of the discharge cylinder is provided with a discharge outlet. A discharge rod for blocking the discharge port is vertically installed inside the discharge cylinder. The discharge cylinder is provided with a handle for driving the discharge rod to move upward to open the discharge port. The snow melting machine also includes a driving component. The discharge rod includes a driven part, a blocking part for blocking the discharge port, and a screw part located below the blocking part, arranged sequentially from top to bottom. The driving component cooperates with the driven part to drive the screw part to rotate, so as to push the material from the discharge port toward the discharge outlet when the discharge port is opened.

[0007] This utility model provides a smooth-discharging slush machine. By incorporating a driving component, the slush discharge rod includes, from top to bottom, a driven part, a sealing part for blocking the discharge port, and a screw part located below the sealing part. When the user needs to open the discharge port, the driving component and the driven part cooperate to drive the screw part to rotate. This causes the slush entering the discharge cylinder from the discharge port to not only fall due to its own gravity but also be propelled by the screw part from the discharge port towards the discharge outlet, creating a forced discharge effect. This achieves smooth, fast, and thorough discharge. Furthermore, by shortening the residence time of the slush at the low-temperature discharge port, it avoids the conditions for "secondary freezing," thus preventing clumping and resulting in a smoother and more refreshing taste. Because the slush is completely discharged from the discharge cylinder under the pushing action of the screw part, it also avoids the problem of residual slush dripping, saving the user the trouble of cleaning.

[0008] In a preferred embodiment, the discharge cylinder includes a discharge section and an extension section connected above the discharge section. The discharge port is opened in the discharge section. The inner diameter of the extension section is larger than the inner diameter of the discharge section. The handle drives the discharge rod to move upward. The sealing part opens the discharge port and is located inside the extension section. The sealing part is in clearance fit with the extension section.

[0009] By configuring the discharge cylinder to include a discharge section and an extension section connected above the discharge section, with the inner diameter of the extension section being larger than that of the discharge section, the sealing part is located within the extended section with its enlarged inner diameter when the discharge port is open, thus achieving a clearance fit with the extension section. Therefore, during the rotation of the screw section, even if the sealing part rotates with the screw section, the clearance fit between the sealing part and the extension section eliminates the sliding friction resistance between them. This allows the power of the driving component to be concentrated on the rotational motion of the screw section, resulting in smoother rotation of the screw section to ensure efficient and thorough discharge. At the same time, it reduces wear on the sealing part, thereby ensuring the sealing effect of the sealing part when the discharge port is closed. Of course, it also avoids frictional noise between the sealing part and the discharge cylinder during rotation, achieving a noise reduction effect.

[0010] In a preferred embodiment, the extension gradually expands from bottom to top; or, the extension is connected to the discharge section by a radially outwardly extending stepped surface.

[0011] Whether the extension section gradually expands from bottom to top or the extension section is connected to the discharge section via a stepped surface, the sealing part can move upwards into the extension section with a larger inner diameter when the discharge port is opened, thus reducing friction by fitting with the gap of the extension section. The sealing part can also reliably seal the discharge port within the discharge section. If the extension section gradually expands from bottom to top, the inner circumference of the extension section can form a downward inclined surface to prevent the accumulation of ice and sand. Therefore, if the ice and sand adhering to the sealing part moves upwards, it can fall onto the inclined surface and, guided by the inclined surface, fall back into the discharge section and be discharged from the discharge port, resulting in more thorough discharge. If a stepped surface connection is used, the inner wall structure of the discharge cylinder is more regular and easier to manufacture, such as by thinning the inner wall of the extension section of the discharge cylinder.

[0012] In a preferred embodiment, a rotatable stirring screw is horizontally installed inside the hopper. The end of the stirring screw is provided with an active tooth that extends into the discharge cylinder. The active tooth forms the driving member. The driven part includes a driven tooth located above the sealing part. The active tooth and the driven tooth mesh to drive the discharge rod to rotate.

[0013] Since the mixing screw in the hopper itself has the function of mixing and shaping slush, by using the active teeth set at the end of the mixing screw to form a driving component, the mixing screw also integrates the function of driving the discharge rod. The rotational power of the mixing screw is reused, eliminating the need to set up an independent motor or transmission parts for the discharge rod. This achieves functional integration and simplifies the components of the whole machine, reducing the driving cost of the discharge rod.

[0014] In a preferred embodiment, the number of teeth of the driving tooth is not less than the number of teeth of the driven tooth.

[0015] By ensuring that the number of teeth on the driving teeth is not less than the number of teeth on the driven teeth, the rotational speed of the discharge rod is not less than that of the stirring screw, achieving an accelerated transmission effect. This allows the discharge rod to push more ice sand per unit time, improving discharge efficiency and preventing ice sand from accumulating at the outlet. Furthermore, for traditional discharge rods with a diameter smaller than the stirring screw, ensuring the number of teeth on the driving teeth is not less than the number of teeth on the driven teeth compensates for the smaller diameter. This avoids making the overall machine too bulky due to excessively thick discharge rods and discharge cylinders, while also achieving highly efficient discharge.

[0016] In a preferred embodiment, the driving member is mounted on the top of the discharge cylinder, and a coupling or transmission gear is provided between the driving member and the driven part.

[0017] By mounting the drive unit at the top of the discharge cylinder and using a coupling or transmission gear to drive the drive unit and driven part, the screw section of the discharge rod effectively pushes the material, accelerating the discharge of the ice slush. Furthermore, the independent mounting of the drive unit at the top of the discharge cylinder provides greater flexibility for users, allowing them to rotate the discharge rod manually or by controlling the motor as needed.

[0018] In a preferred embodiment, a rotatable stirring screw is horizontally installed inside the hopper, and a baffle is provided inside the hopper near the discharge port, the baffle being located behind the discharge port along the rotation direction of the stirring screw.

[0019] By setting a baffle part, which is located behind the discharge port along the rotation direction of the stirring screw, the ice sand will be pushed towards the discharge port during the rotation of the stirring screw. When the ice sand encounters the baffle part, it is blocked and guided, and naturally deflects towards the discharge port, thereby avoiding the ineffective circulation of ice sand in the hopper and improving the discharge efficiency of the hopper. This application enables not only the discharge cylinder to discharge quickly and thoroughly, but also the hopper to discharge more thoroughly.

[0020] In a preferred embodiment, the peripheral wall of the discharge cylinder is embedded in the hopper, the discharge port penetrates through the peripheral wall of the discharge cylinder, and the peripheral wall of the discharge cylinder forms the material blocking part.

[0021] By embedding the peripheral wall of the discharge cylinder into the hopper, a portion of its own peripheral wall naturally acts as a baffle, achieving motion guidance for the slush using a simple structure. Simultaneously, the tight connection between the discharge cylinder and the hopper allows the material propelled by the agitator screw to smoothly flow from the hopper into the discharge cylinder, improving discharge efficiency.

[0022] In a preferred embodiment, the discharge cylinder is equipped with a converter that is linked to the handle. The driven part includes a driven rod connected to the sealing part and a limiting boss located at the top of the driven rod and radially expanding. The converter is provided with a limiting hole through which the driven rod passes and a limiting groove for accommodating the limiting boss. The limiting boss is axially limited in the limiting groove and rotates circumferentially along the limiting groove.

[0023] By setting an adapter, the limiting groove of the adapter axially supports the limiting boss of the driven part, thereby driving the adapter to move upward when the user operates the handle, thus opening the discharge port. The limiting boss is axially limited in the limiting groove through the limiting hole through which the driven rod passes and rotates circumferentially along the limiting groove. Therefore, the driven part as a whole and the adapter can rotate relative to each other, avoiding rotational friction and achieving more effortless rotation of the screw part. Thus, the adapter ensures that the discharge rod can move up and down reliably while also ensuring smooth rotation of the discharge rod.

[0024] In a preferred embodiment, the side of the sealing part is provided with a first sealing rib and a second sealing rib, the first sealing rib abutting against the upper edge of the discharge port, and the second sealing rib abutting against the lower edge of the discharge port.

[0025] By setting the first and second sealing ribs, a more comprehensive sealing effect is formed on the upper and lower edges of the discharge port. At the same time, the sealing ribs can flexibly deform to seal the discharge port, resulting in less friction and smoother movement when the stirring rod rotates and moves up and down.

[0026] In a preferred embodiment, a rotatable stirring screw is horizontally installed inside the hopper, and stirring blades are spirally arranged on the outer periphery of the stirring screw, with the axial distance between adjacent stirring blades decreasing towards the discharge port.

[0027] The axial distance between adjacent mixing blades on the mixing screw decreases towards the discharge port, thereby generating a larger axial driving force. This can quickly push the formed ice sand out of the discharge port, preventing the ice sand from accumulating there. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0047] like Figure 1 As shown, in one embodiment of the present invention, a snow melting machine with smooth discharge is provided, including a hopper 10 and a discharge cylinder 20 installed on the side of the hopper 10. A discharge port 11 is connected between the hopper 10 and the discharge cylinder 20. A discharge outlet is provided at the bottom of the discharge cylinder 20. A discharge rod 30 for blocking the discharge outlet 11 is vertically installed inside the discharge cylinder 20. A handle 40 is provided on the discharge cylinder 20. The handle 40 is used to drive the discharge rod 30 to move upward to open the discharge outlet 11. The snow melting machine also includes a driving component 50.

[0048] like Figure 2 As shown, the discharge rod 30 includes a driven part 31, a blocking part 32 for blocking the discharge port 11, and a screw part 33 located below the blocking part 32, arranged sequentially from top to bottom. The driving member 50 cooperates with the driven part 31 to drive the screw part 33 to rotate, so as to push the material from the discharge port 11 toward the discharge outlet when the discharge port 11 is opened.

[0049] Combination Figure 1-3 As shown, the present invention provides a snow melting machine with smooth material discharge. By setting a driving component 50, and the discharge rod 30 including a driven part 31, a blocking part 32 for blocking the discharge port 11 and a screw part 33 located below the blocking part 32 arranged sequentially from top to bottom, when the user needs to open the discharge port 11 to discharge material, the driving component 50 and the driven part 31 cooperate to drive the screw part 33 to rotate.

[0050] For example, the screw section 33, driven by the drive member 50, moves along... Figure 3 The rotating arrow indicates that the slush entering the discharge cylinder 20 from the discharge port 11 is forced to move from the discharge port 11 towards the discharge outlet as it is discharged downwards along the discharge cylinder 20. This forced discharge ensures smooth, rapid, and thorough discharge. Furthermore, by shortening the residence time of the slush at the low-temperature discharge port 11, the conditions for "secondary freezing" of the slush are avoided, preventing clumping and resulting in a smoother and more refreshing taste. Because the slush is completely discharged from the discharge cylinder 20 under the pushing action of the screw 33, the problem of residual slush dripping is also avoided, saving users the trouble of cleaning.

[0051] The specific structure of the discharge cylinder is not limited in this utility model:

[0052] For example, such as Figure 1-10 As shown, in a preferred embodiment, the discharge cylinder 20 is a straight cylinder with a uniform inner diameter. Therefore, only the discharge rod needs to be improved based on the traditional snow melting machine. The discharge cylinder part has minimal changes and does not require additional molds, making processing and production convenient.

[0053] like Figure 11 As shown, in another preferred embodiment, the discharge cylinder 20 includes a discharge section 21 and an extension section 22 communicating above the discharge section 21. The discharge port 11 is opened in the discharge section 21, and the inner diameter of the extension section 22 is larger than the inner diameter of the discharge section 21. When the handle drives the discharge rod upward, the sealing part 32 opens the discharge port 11 and is located within the extension section 22, with the sealing part 32 and the extension section 22 in a clearance fit. More preferably, as shown... Figure 11 As shown, extension segment 22 gradually expands from bottom to top.

[0054] Combination Figure 11By configuring the discharge cylinder 20 to include a discharge section 21 and an extension section 22 connected above the discharge section 21, and with the inner diameter of the extension section 22 being larger than that of the discharge section 21, when the discharge port 11 is opened, the sealing part 32 is located within the extension section 22 with an enlarged inner diameter to achieve a clearance fit with the extension section 22. Therefore, during the rotation of the drive screw part 33, even if the sealing part 32 rotates with the screw part 33, the clearance fit between the sealing part 32 and the extension section 22 eliminates the sliding friction resistance between them. This allows the power of the drive component 50 to be concentrated on the rotational motion of the screw part 33, achieving smoother rotation of the screw part 33 to ensure efficient and thorough discharge. At the same time, it also reduces wear on the sealing part 32, thereby ensuring the sealing effect of the sealing part 32 when closing the discharge port. Of course, it also avoids frictional noise between the sealing part 32 and the discharge cylinder 20 during rotation, achieving a noise reduction effect.

[0055] Of course, in other preferred embodiments of the present invention, the extension section 22 and the discharge section 21 may optionally be connected by a radially outwardly extending stepped surface.

[0056] Whether the extension section 22 is gradually expanded from bottom to top or the extension section 22 is connected to the discharge section 21 through a stepped surface, the sealing part 32 can move upward into the extension section 22 with a larger inner diameter when the discharge port 11 is opened, and the gap fit with the extension section 22 reduces friction. The sealing part 32 can also reliably seal the discharge port 11 within the discharge section 21. If the extension section 22 is gradually expanded from bottom to top, the inner circumferential surface of the extension section 22 can form an inclined surface from top to bottom to prevent the accumulation of ice sand. Therefore, if the ice sand adhered to the sealing part 32 moves upward during the upward movement, the adhered ice sand can fall onto the inclined surface and fall back into the discharge section 21 under the guidance of the inclined surface, and then be discharged from the discharge port, making the discharge more thorough. If the stepped surface connection is used, the inner wall structure of the discharge cylinder 20 is more regular and easier to process and manufacture. For example, it can be achieved by thinning the inner wall of the extension section 22 of the discharge cylinder 20.

[0057] It should also be noted that this utility model does not limit the connection method between the driven part 31, the sealing part 32, and the screw part 33 of the discharge rod 30, such as... Figure 2 As shown, in a preferred embodiment, the driven part 31, the sealing part 32, and the screw part 33 are fixedly connected as a single unit. When the driving member 50 drives the driven part, the driven part 31, the sealing part 32, and the screw part 33 rotate synchronously. This configuration simplifies the structure of the discharge rod, ensures reliable transmission of the driving member 50, and allows the screw part 33 of the discharge rod 30 to rotate smoothly, resulting in smooth and thorough material discharge.

[0058] Of course, in other preferred embodiments, the sealing part 32 adopts a hollow structure, and the bottom end of the driven part 31 is fixedly connected to an extension rod. The extension rod passes through the hollow hole of the sealing part 32 and is fixedly connected to the screw part 33. The driven part 31 slides between the extension rod and the hollow hole of the sealing part 32. For example, a rib and an annular groove are respectively provided from the extension rod and the hollow hole of the sealing part 32. The rib slides in the groove so that when the driving member 50 drives the driven part 31, the driven part 31 rotates relative to the sealing part 32. With this configuration, it is only necessary to limit the sealing part 32 with the discharge cylinder 20 or other limiting structures when the discharge port 11 is open. For example, the discharge cylinder 20 is configured as the above-mentioned discharge section 21 and an extension section 22 connected above the discharge section with a gradually increasing outer diameter. When the discharge port is open, the extension section 22 supports the sealing part 32. This configuration allows the driven part 31 to directly drive the screw part 33 to rotate, while the sealing part 32 remains stationary, avoiding wear on the sealing part 32 and thus ensuring the reliability and sealing effect of the sealing part 32 when sealing the discharge port 11.

[0059] like Figure 1-10 As shown, in a preferred embodiment, a rotatable stirring screw 60 is horizontally installed inside the hopper 10, such as... Figure 3 As shown, the end of the stirring screw 60 is provided with a drive tooth 51 that extends into the discharge cylinder 20. The drive tooth 51 forms a driving element 50, such as... Figure 2 As shown, the driven part 31 includes a driven tooth 313 located at the top of the sealing part 32. After the discharge rod 30 moves upward to open the discharge port 11, the driven tooth 313 meshes with the driving tooth 51 to drive the discharge rod to rotate. More preferably, the number of teeth of the driving tooth 51 is not less than the number of teeth of the driven tooth 313.

[0060] Since the stirring screw 60 in the hopper 10 has the function of stirring and shaping slush, the stirring screw 60 also integrates the function of driving the discharge rod 30 by using the active tooth 51 at the end of the stirring screw 60 to form the driving component 50. The rotational power of the stirring screw 60 is reused, and there is no need to set up an independent motor or transmission component for the discharge rod 30. This achieves functional integration and simplifies the components of the whole machine, reducing the driving cost of the discharge rod 30.

[0061] By ensuring that the number of teeth on the driving tooth 51 is not less than the number of teeth on the driven tooth 313, the rotational speed of the discharge rod 30 is not less than that of the stirring screw 60, thus achieving an accelerated transmission effect. This allows the discharge rod 30 to push more ice sand per unit time, improving discharge efficiency and preventing ice sand from accumulating at the outlet 11. Furthermore, for traditional discharge rods with a diameter smaller than the stirring screw 60, the fact that the number of teeth on the driving tooth 51 is not less than the number of teeth on the driven tooth 313 compensates for the smaller diameter of the discharge rod 30. This avoids making the entire machine too bulky due to excessively thick discharge rods 30 and discharge cylinder 20, while also achieving efficient discharge.

[0062] Of course, the specific structure of the driving component 50 is not limited to the one described above. For example, in other preferred embodiments, the driving component 50 is installed at the top of the discharge cylinder 20, and a coupling or transmission gear is provided between the driving component 50 and the driven part 31. The driving component 50 can be a motor or a manual crank.

[0063] By mounting the drive unit 50 at the top of the discharge cylinder 20 and using a coupling or transmission gear to drive the drive unit 50 and the driven part 31, the screw part 33 of the discharge rod 30 effectively pushes the material, accelerating the discharge of the ice slush. Moreover, since the drive unit 50 is independently mounted at the top of the discharge cylinder 20, it is more flexible for users to operate, and the rotation of the discharge rod 30 can be achieved manually or by controlling the motor according to actual needs.

[0064] like Figure 1 , 4 As shown, in a preferred embodiment, a transition piece 70 linked to the handle 40 is installed inside the discharge cylinder 20. The driven part 31 includes a driven rod 311 connected to the sealing part 32 and a limiting boss 312 located at the top of the driven rod 311 and radially expanding. The transition piece 70 is provided with a limiting hole 71 through which the driven rod 311 passes and a limiting groove 72 for accommodating the limiting boss 312. The limiting boss 312 is axially limited within the limiting groove 72 and rotates circumferentially along the limiting groove 72. Figure 4 As shown, in this embodiment, the driven part 31 includes a driven tooth 313 sleeved on the outer periphery of the driven rod 311, and the end of the stirring screw 60 is provided with an active tooth 51 extending into the discharge cylinder 20. The active tooth 51 forms a driving member 50. After the discharge rod 30 moves up to open the discharge port 11, the driven tooth 313 meshes with the active tooth 51 for transmission.

[0065] Of course, in this embodiment, the driving component 50 can also be a motor fixed to the top of the discharge cylinder, with the motor shaft extending into the discharge cylinder and connected to a coupling. The limiting boss 312 is inserted into the coupling to achieve transmission. In fact, the motor shaft can also be directly set to a flat position, and the limiting boss 312 can be set with a hole that mates with the flat position to achieve direct transmission between the shaft and the limiting boss.

[0066] By setting the adapter 70, the limiting groove 72 of the adapter 70 axially supports the limiting boss 312 of the driven part 31, thereby driving the adapter 70 to move together when the user operates the handle 40, and thus pulling the driven part 31 upward to open the discharge port 11; the limiting hole 71 through which the driven rod 311 passes, and the limiting boss 312 is axially limited in the limiting groove 72 and rotates circumferentially along the limiting groove 72. Therefore, the driven part 31 as a whole rotates relative to the adapter 70, avoiding rotational friction and realizing more effortless rotation of the screw part 33. Therefore, by using the adapter 70, it is possible to ensure that the discharge rod 30 can move up and down reliably while ensuring that the discharge rod 30 can rotate smoothly.

[0067] Combination Figure 1 , 3 As shown in Figure 5, to enable effortless operation for the user, the handle 40 includes a long arm 41 and a short arm 42 connected at an angle. The connection between the long arm 41 and the short arm 42 is hinged to the side wall of the discharge cylinder 20. The long arm 41 extends outside the discharge cylinder 20. The adapter 70 is provided with a socket that is linked to the free end of the short arm. Preferably, the snow melting machine also includes a return spring 80 that abuts against the top of the adapter 70 to push the discharge rod 30 downward to reset. The return spring 80 is located inside the discharge cylinder 20. The upper end of the return spring 80 abuts against the top wall of the discharge cylinder 20, and the lower end abuts against the adapter 70. Alternatively, a radially enlarged boss is provided on the discharge rod, and the lower end of the return spring abuts directly against the boss of the discharge rod.

[0068] like Figure 5 , 6 As shown, in a preferred embodiment, the side of the sealing part 32 is provided with a first sealing rib 321 and a second sealing rib 322. The first sealing rib 321 abuts against the upper edge of the discharge port 11, and the second sealing rib 322 abuts against the lower edge of the discharge port 11.

[0069] By setting the first sealing rib 321 and the second sealing rib 322, a more comprehensive sealing effect is formed on the upper and lower edges of the discharge port 11. At the same time, the sealing ribs can flexibly deform to seal the discharge port 11, resulting in less friction and smoother movement when the stirring rod rotates and moves up and down.

[0070] like Figure 7 , 8 As shown in Figures 9 and 1, in a preferred embodiment, a rotatable stirring screw 60 is horizontally installed inside the hopper 10. A baffle 12 is provided inside the hopper 10 near the discharge port 11, and the baffle 12 is located behind the discharge port 11 along the rotation direction of the stirring screw 60. More preferably, the peripheral wall of the discharge cylinder 20 is embedded in the hopper 10, and the discharge port 11 penetrates through the peripheral wall of the discharge cylinder 20, forming the baffle 12.

[0071] By setting a baffle 12, which is located behind the discharge port 11 along the rotation direction of the stirring screw 60, the stirring screw 60 will push the ice sand towards the discharge port 11 during rotation. When the ice sand encounters the baffle 12, it will be blocked and guided, and will naturally deflect towards the discharge port 11, thereby avoiding ineffective circulation of ice sand in the hopper 10 and improving the discharge efficiency of the hopper 10. This makes it possible for not only the discharge cylinder 20 to discharge material quickly and thoroughly, but also the hopper 10 to discharge material more thoroughly.

[0072] By embedding the peripheral wall of the discharge cylinder 20 into the hopper 10, a portion of its own peripheral wall naturally acts as a baffle 12, thus achieving motion guidance for the slush using a simple structure. At the same time, the connection between the discharge cylinder 20 and the hopper 10 is tight, allowing the material pushed by the stirring screw 60 to enter the discharge cylinder 20 from the hopper 10 more smoothly, improving discharge efficiency.

[0073] like Figure 10 As shown, preferably, the outer periphery of the stirring screw 60 is spirally arranged with stirring blades 61, and the axial distance between adjacent stirring blades 61 decreases towards the discharge port 11. For example, the stirring blades 61 include a first blade 611, a second blade 612, a third blade 613, and a fourth blade 614 arranged sequentially away from the discharge port 11, wherein the axial distance d1 between the first blade 611 and the second blade 612 is less than the axial distance d2 between the third blade 613 and the fourth blade 614.

[0074] The axial distance between adjacent stirring blades 61 on the stirring screw 60 decreases towards the discharge port 11, thereby generating a larger axial driving force, which can quickly push the formed ice sand outside the discharge port 11 and prevent the ice sand from accumulating in the discharge port 11.
