[0048] This application discloses a shredder for turning fruits and vegetables into shreds or strips. A shredder typically includes a housing and a cutting device installed inside the housing for cutting fruits and vegetables. The inventors have found that existing cutting devices include a blade holder and multiple blades spaced circumferentially along the blade holder. Because the multiple blades are all located on the same horizontal plane, the cutting range is limited, resulting in incomplete chopping of fruits and vegetables and unsatisfactory shredding effect. Therefore, this application provides a cutting device that, by setting an angle between a first blade body and a second blade body, allows the cutting device to have multiple cutting angles, increasing the cutting range, enabling rapid and complete chopping of fruits and vegetables, effectively improving cutting efficiency, and achieving better cutting results.

[0049] Please see Figure 1 and Figure 2 The diagram shown is a structural schematic of a shredding machine according to one embodiment. The shredding machine in this embodiment includes a housing 10, a drive mechanism 20, a cutting device 30, and a material-stopping assembly 40.

[0050] The housing 10 has an internal cavity and a feed inlet at the top. The cavity can accommodate not only the cutting device 30 but also fruits and vegetables fed into it through the feed inlet. The side wall of the housing 10 has a discharge outlet connecting the inside and outside. Fruits and vegetables are fed into the housing 10 through the feed inlet, cut by the cutting device 30, and discharged through the discharge outlet. The specific shape of the housing 10 is not limited here; for example, it can be circular or polygonal. This embodiment describes the housing 10 as circular.

[0051] The drive mechanism 20 is used to drive the cutting device 30 to rotate for cutting operations. The drive mechanism 20 includes a drive motor mounted on the housing 10 and a rotating shaft with one end connected to the drive motor and the other end extending into the housing 10.

[0052] The cutting device 30 is installed inside the housing 10 and is connected to the rotating shaft of the drive mechanism 20. It can rotate under the drive of the drive mechanism 20 to realize the shredding of fruits and vegetables.

[0053] The material blocking assembly 40 is disposed on the outer wall of the housing 10 and located at the discharge port, and is used to block the material discharged from the discharge port to prevent material splashing.

[0054] Please see Figures 3 to 5 As shown, the cutting device 30 includes at least one first cutter 31 and at least one second cutter 32, both of which are connected to the rotating shaft of the drive mechanism 20.

[0055] The first cutting blade 31 has a first blade body 311 extending along a first direction, and a first cutting edge 312 is formed on one side of the first blade body 311. The first cutting edge 312 performs cutting operations by rotating the first cutting blade 31. The first cutting blade 31 can be an arc-shaped cutting blade, with one end connected to the rotating shaft of the drive mechanism 20 and the other end extending along the positive or negative direction of the first direction to form the first blade body 311. Of course, the first cutting blade 31 can also be an approximately S-shaped cutting blade, with its middle part connected to the rotating shaft of the drive mechanism 20 and its two ends extending in opposite directions along the first direction to form two first blade bodies 311. The first cutting edge 312 is formed on the two diagonal edges of the first cutting blade 31.

[0056] Similarly, the second cutter 32 has a second cutter body 321 extending along the first direction, and a second cutting edge 322 is formed on one side of the second cutter body 321. The second cutting edge 322 performs cutting by rotating the second cutter 32. The second cutter 32 can also be an arc-shaped cutter, with one end connected to the rotating shaft of the drive mechanism 20 and the other end extending along the positive or negative direction of the first direction to form the second cutter body 321. Of course, the second cutter 32 can also be an approximately S-shaped cutter, with its middle part connected to the rotating shaft of the drive mechanism 20 and its two ends extending in opposite directions along the first direction to form two second cutter bodies 321. The second cutting edge 322 is formed on the two diagonal edges of the second cutter 32.

[0057] The first blade 311 and the second blade 321 are staggered along the circumferential axis of the drive mechanism 20. The first blade 311 is parallel to the first direction, and the second blade 321 is set at an angle to the first direction. In this way, the first blade 311 and the second blade 321 are set at an angle, which not only gives the cutting device multiple cutting angles, but also increases the cutting range, which can quickly and completely chop fruits and vegetables, effectively improve cutting efficiency, and achieve better cutting results.

[0058] It should be noted that the first direction mentioned above is a horizontal direction perpendicular to the axial direction of the housing 10.

[0059] It should be noted that "at least one" means that the quantity is one or more, such as two, three, four, etc.

[0060] In this embodiment, the angle between the second blade 321 and the first direction can be between 0 and 60 degrees.

[0061] Please see Figure 5 In some embodiments of this application, the first cutter 31 and the second cutter 32 can be connected to the shaft of the drive mechanism 20 through the cutter holder 33. By setting the cutter holder 33, the first cutter 31 and the second cutter 32 can be supported, which facilitates the connection of the first cutter 31 and the second cutter 32 to the shaft of the drive mechanism 20.

[0062] The blade holder 33 can be a plate-shaped structure, including a main body 331 located at the center, a first connecting part 332 and a second connecting part 333 disposed around the main body 331. The first connecting part 332 and the second connecting part 333 are arranged alternately, with the first connecting part 332 connected to the first cutter 31 and the second connecting part 333 connected to the second cutter 32.

[0063] In this embodiment, both the first cutter 31 and the second cutter 32 are detachably connected to the cutter holder 33, which makes it convenient for the user to replace the cutter.

[0064] The first connecting part 332 and the second connecting part 333 can be detachably connected to the main body 331 via fasteners such as bolts, or the first connecting part 332 and the second connecting part 333 can be integrally formed with the main body 331. Figure 5 As shown, the main body 331 is parallel to the first direction, the first connecting part 332 is formed by the horizontal extension of the edge of the main body 331, and the second connecting part 333 is formed by bending the edge of the main body 331 upward. By setting the tool holder 33 as an integrally formed structure, not only can the assembly efficiency be improved by reducing the number of parts, but the structural strength of the tool holder can also be increased.

[0065] In some other embodiments of this application, the main body 331 is parallel to the first direction, and the first connecting part 332 and the second connecting part 333 are both formed by horizontally extending from the edge of the main body 331. That is, the blade holder 33 is a flat structure, and the second cutter 32 can be configured as a bent structure. The second cutter 32 may include a third connecting part connected to the second connecting part 333 on the blade holder 31. The end of the third connecting part extends along the first direction and is bent upward to form a second blade body 321.

[0066] Please see again Figures 1 to 2 The cutting device 30 on the shredder can be provided in two sets. The two sets of cutting devices 30 are arranged at intervals along the axial direction of the rotating shaft, and the first cutter 31 in the upper cutting device 30 and the first cutter 31 in the lower cutting device 30 are arranged alternately.

[0067] Please see Figure 6 In some embodiments of this application, the baffle assembly 40 may include an upper cover 41, a front baffle 42, and a side baffle 43.

[0068] The top cover 41 is a U-shaped frame with an opening facing downwards, and one side of each of its two side walls can be connected to the outer side wall of the housing 10 via bolts or other fasteners. The front baffle 42 can also be a U-shaped frame with an opening facing downwards, one end of which is connected to the front end of the top cover 41 away from the housing 10, and the other end is slightly inclined downwards to block the material sprayed from the discharge port and prevent the material from splashing upwards. The side baffles 43 can also be connected to the opposite sides of the top cover 41 via bolts or other fasteners. By setting the side baffles 43, the material sprayed from the discharge port can be blocked to prevent the material from splashing to both sides.

[0069] Furthermore, the front baffle 42 and the upper cover 41 are rotatably connected by an adjusting member 44, which is used to adjust the rotation angle of the front baffle 42, thereby controlling the distance of material spraying. A positioning mechanism is also provided between the front baffle 42 and the upper cover 41, which is used to position and fix the front baffle 42 after it is adjusted to a suitable angle.

[0070] Specifically, please see Figure 6 The positioning mechanism may include an arc-shaped groove 421, a corresponding insertion hole 411, and a bolt inserted into the arc-shaped groove 421 and the insertion hole 411. One of the arc-shaped groove 421 and the insertion hole 411 is located on the side wall of the front baffle 42, and the other is located on the side wall of the upper cover 41. That is, the positions of the arc-shaped groove 421 and the insertion hole 411 can be adjusted as needed, as long as the arc-shaped groove 421 and the insertion hole 411 correspond. For example, the arc-shaped groove 421 is formed on both side walls of the front baffle 42, and the insertion hole 411 is formed on both side walls of the upper cover 41, or the arc-shaped groove 421 is formed on both side walls of the upper cover 41, and the insertion hole 411 is formed on both side walls of the front baffle 42.
