The ice breaking piece 4 is used to interrupt the ice continuously squeezed out of the ice outlet 31. The barrel 1 is provided with an ice inlet 11, and the ice inlet 11 is opposite to one end of the variable pitch multi-thread screw 2. In the present embodiment, the thread 21 and the rod body 23 are an integrally formed structure, the number of the ice outlets 31 is six, and the six ice outlets 31 are evenly arranged along the circumferential direction of the ice outlet head 3. The cross-section of the ice outlet 31 is a circular structure, the ice outlet head 3 is installed at the front end of the barrel 1, one end of the variable-pitch multi-threaded screw 2 can be rotatably installed inside the rear end of the barrel 1, and the other end of the variable-pitch multi-threaded screw 2 can be rotatably installed on the ice outlet head 3, and the other end of the variable-pitch multi-threaded screw 2 is connected to an external driving motor for driving the variable-pitch multi-threaded screw 2 to rotate, and the ice inlet 11 is located above the variable-pitch multi-threaded screw 2. When working, the external driving motor drives the variable-pitch multi-threaded screw 2 to rotate, and then ice cubes are added from the ice inlet 11. The ice cubes added here can be crushed ice cubes or other shapes. The ice cubes (such as bullet ice) enter the interior of the barrel 1, and the variable pitch multi-threaded screw 2 crushes the ice cubes and conveys them in the direction of the ice outlet head 3. Under the action of the variable pitch structure of the thread 21, the ice cubes are reshaped and squeezed out from the ice outlet 31, and the ice breaking piece 4 is installed on the variable pitch multi-threaded screw 2, and the ice breaking piece 4 rotates synchronously with the variable pitch multi-threaded screw 2. When ice is discharged, the ice breaking piece 4 breaks the ice cubes squeezed out of the ice outlet 31 by rotating, thereby completing the production of columnar ice; the present application uses the barrel 1, the ice inlet 11, the variable pitch multi-threaded screw 2, the thread 21, the rod body 23, the ice outlet head 3, the ice outlet 31 and the ice breaking piece 4 to make the screw force uniform and not eccentric, so it is easy to squeeze out ice cubes, which is beneficial to improving the ice squeezing efficiency, and the ice cubes become harder the more they are squeezed, and the ice cubes can be reshaped and made more compact at the same time.

[0034] Preferably, the ice outlet head 3 is detachably mounted on the front end of the cylinder 1 by means of a threaded connection. The threaded detachable structure allows the ice outlet head 3 to be quickly and conveniently replaced, which is not only conducive to improving the efficiency of disassembly and assembly of the ice outlet head 3, but also allows different types of ice outlet heads 3 to be replaced to squeeze out ice of different shapes, thereby satisfying different usage scenarios of ice cubes. Furthermore, the cross-sectional shape of the ice outlet 31 includes, but is not limited to, a circle, a triangle, a quadrilateral, a rhombus, a trapezoid, a pentagon or a hexagon, and the structure of the detachable ice outlet head 3 allows the extrusion of ice of different shapes, thereby improving the usage scenarios of ice cubes.

[0035] In this embodiment, the ice inlet 1 is configured as a trumpet-shaped structure that is wide at the top and narrow at the bottom, so that ice cubes can be easily poured into the cylinder 1 from the ice inlet 1 and the ice cubes are not easy to leak out.

[0036] like Figure 2 and Figure 5 As shown, the variable pitch multi-thread screw 2 is a variable pitch double-thread screw structure. In this embodiment, the number of the threads 21 is two, and the two threads 21 are respectively arranged on the rod body 23, and the two threads are arranged along the rod body 23 in a mirror-symmetrical manner. The number of threads of the variable pitch multi-thread screw 2 is preferably set to two, which not only facilitates the processing and manufacturing of the variable pitch multi-thread screw 2 and reduces the difficulty of manufacturing and processing, but also is more conducive to ensuring its rotation balance and is not prone to jamming.

[0037] like Figure 2 and Figure 5 As shown, the pitch of the thread 21 gradually decreases along the conveying direction of the rod body 23. In this embodiment, the pitch of the thread 21 gradually decreases along the central axis direction of the rod body 23, that is, from the direction of ice inlet to ice outlet, the distance between two adjacent screw blades gradually decreases, and the pitch at the ice inlet 11 is 20-40mm, preferably 30mm, so as to facilitate the re-crushing and extrusion of ice cubes, thereby achieving the effect of improving the working efficiency of the ice making extrusion device.

[0038] like Figure 2 and Figure 5 As shown, the cross section of the thread 21 in the radial direction is a tapered structure with a thin top and a thick bottom, and the thickness ratio of the lower thick end to the upper thin end is in the range of 1.1-4.7. In this embodiment, the cross section of the thread 21 in the radial direction is a tapered structure with a thin top and a thick bottom. Specifically, in the tapered structure with a thin top and a thick bottom, the thickness of the lower thick end is in the range of 4-7mm, and the thickness of the lower thick end is preferably 5mm, and the thickness of the upper thin end is in the range of 1.5-3.5mm, and the thickness of the upper thin end is preferably 2.5mm. The above arrangement is conducive to improving the structural stability of the variable pitch multi-thread screw 2.

[0039] like Figure 2 and Figure 5 As shown, the ratio range of the maximum pitch M of the thread 21 to the minimum pitch N of the thread 21 is 1-4. In this embodiment, the maximum pitch M of the thread 21 is in the range of 20-40 mm, the maximum pitch M of the thread 21 is preferably 35 mm, the minimum pitch N of the thread 21 is in the range of 10-20 mm, and the minimum pitch N of the thread 21 is preferably 15 mm. The above arrangement is conducive to improving the structural stability of the variable pitch multi-thread screw 2.

In this embodiment, the arcuate concave surface 12 and the crushing ridges 13 are provided on the inner wall of the cylinder 1, and each of the arcuate concave surfaces 12 is located between two adjacent crushing ridges 13. Specifically, along the circumferential direction of the inner wall of the cylinder 1, the depression depth of the arcuate concave surface 12 between two adjacent crushing ridges 13 gradually deepens, and the cross-section of the crushing ridge 13 is a trapezoidal structure. The front end length of the crushing ridge 13 is smaller than the rear end length. The inner wall crushing structure is formed by the alternating arcuate concave surfaces 12 and the crushing ridges 13. When the ice cubes enter the interior of the cylinder 1, the ice cubes are quickly crushed and re-shaped and extruded through the crushing structure of the inner wall of the cylinder 1 and the rotation of the variable pitch multi-thread screw 2, so that the extruded ice is more compact, thereby achieving the effect of improving the crushing efficiency of the ice making extrusion device.

[0041] like Figure 1-2 As shown, the ice breaking component 4 includes a mounting column 41 and a protrusion 42; the mounting column 41 is installed on the variable pitch multi-thread screw 2, and the plurality of ice outlets 31 are distributed on the periphery of the mounting column 41; the protrusion 42 is installed on the periphery of the mounting column 41, and the protrusion 42 may be directly opposite to the ice outlet 31. In this embodiment, the front end of the variable-pitch multi-threaded screw 2 protrudes from the middle of the ice-dispensing head 3, and the mounting post 41 is installed at the front end of the variable-pitch multi-threaded screw 2. The mounting post 41 is located at the front side of the ice-dispensing head 3, and a plurality of ice outlets 31 are evenly arranged around the mounting post 41 along the circumferential direction of the ice-dispensing head 3. The protrusion 42 is installed on the outer periphery of the mounting post 41, and the mounting post 41 and the protrusion 42 are an integrally formed structure. When dispensing ice, the variable-pitch multi-threaded screw 2 drives the mounting post 41 to rotate, so that the protrusion 42 rotates with the mounting post 41. When the ice cubes squeezed out by the ice-dispensing head 3 touch the rotating protrusion 42, the protrusion 42 breaks the ice, thereby achieving the purpose of breaking ice.

[0042] like Figure 2 As shown, the variable pitch multi-thread screw 2 is provided with a clamping column 24, and the mounting column 41 is provided with a clamping hole 411, and the mounting column 41 is clamped to the mounting column 24 through the clamping hole 411. In this embodiment, the cross-section of the clamping hole 411 is a hexagonal structure, and the mounting column 24 is a hexagonal column structure. Through the hexagonal clamping structure, the mounting column 41 is clamped to the mounting column 24 through the clamping hole 411, which is convenient and fast and not easy to loosen.

In this embodiment, the first rod sleeve 51 is provided at the front end of the variable pitch multi-threaded screw 2, and the second rod sleeve 52 is provided at the rear end of the variable pitch multi-threaded screw 2, so as to avoid the two ends of the variable pitch multi-threaded screw 2 from being worn due to long-term rotation friction with the ice outlet head 3 and the rear end inside the barrel 1, respectively. The first rod sleeve 51 and the second rod sleeve 52 can not only improve the rotation smoothness of the variable pitch multi-threaded screw 2, but also improve its service life.
