[0027] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.
[0028] A food waste crushing and processing device to prevent the top from being sealed, such as Figs. 1 to 4As shown, the assembly includes a barrel body 1, a rotating shaft 2, a moving blade assembly 3, and a fixed blade assembly. The fixed blade assembly is fixedly installed on the inner wall of the barrel body 1. The middle part of the rotating shaft 2 is rotatably installed at the bottom of the barrel body 1 and located at the center of the barrel body 1. The moving blade assembly 3 is installed on the upper part of the rotating shaft 2. The moving blade assembly 3 includes a stirring hub 31 and a stirring arm assembly. The stirring hub 31 is fixedly installed on the upper part of the rotating shaft 2. The inner end of the stirring arm assembly is formed on the outer side of the stirring hub 31. The stirring arm assembly is provided with at least one upright stirring arm 35. The upper end face of the upright stirring arm 35 is higher than the upper end face of the stirring hub 31 in the vertical direction. In traditional systems, the moving blade assembly 3 is located at the bottom of the bucket 1, and the stirring arms are located beside the stirring hub 31. When food waste is added all at once, the food waste gradually shrinks in volume as the water evaporates. At this time, the moving blade assembly 3 can completely cover the food waste in the vertical direction. However, when a large amount of food waste is added in multiple batches, the moving blade assembly 3 has difficulty covering the food waste in the vertical direction. At this time, the food waste above the moving blade assembly 3 tends to form a dome, thus sealing the lower part of the bucket 1 and creating a capping phenomenon. This prevents the water in the lower part of the bucket 1 from evaporating upwards, resulting in the inability of the temperature and humidity meter to accurately detect temperature and humidity data. This utility model prevents the food waste from forming a dome by using an upright stirring arm 35 that is higher than the stirring hub 31. Even if a dome forms, it can be cut and broken up to avoid the capping phenomenon, improve the uniformity of stirring, and enable the temperature and humidity meter to detect accurate temperature and humidity data.
[0029] Specifically, the upper part of the vertical stirring arm 35 is provided with a cutting section 351, the upper part of which protrudes from the stirring hub 31. The radial width D1 of the upper part of the cutting section 351 is smaller than the lower width D2. The cutting section 351 cuts the dome formed by the kitchen waste, thereby separating the kitchen waste above and beside the stirring hub 31 to prevent the formation of the dome. Even if a dome is formed, it can be divided into conical blocks and annular blocks, thereby destroying the sealing of the dome. The cutting section 351 is trapezoidal, which can improve the destructive power to the dome and improve stability and reliability. D1 is greater than 0, and the upper part of the cutting section 351 has a certain width in the radial direction so that the linear velocity of the vertical stirring arm 35 is much greater than the linear velocity of the stirring hub 31.
[0030] Specifically, the cutting section 351 has an inner cutting slope 352 on the side facing the mixing hub 31, and an outer cutting slope 353 on the side facing the inner wall of the bucket 1. The inner cutting slope 352 divides the kitchen waste above the mixing hub 31 into conical blocks. Since the conical blocks are larger at the top and smaller at the bottom, they are difficult to stabilize on the mixing hub 31 and thus fall downwards, thereby compromising the seal of the dome. Moisture at the bottom of the bucket 1 can be discharged upwards from the center of the dome. Even if the outer part of the dome does not fall, it can still ensure that the thermometer and hygrometer detect accurate temperature and humidity data. Furthermore, the inner cutting slope 352 and the outer cutting slope 353 can also act as guides, causing the conical blocks and annular blocks to fall downwards.
[0031] Specifically, the upper part of the mixing hub 31 is provided with a guide protrusion 311, the upper diameter of which is smaller than the lower diameter, and the outer side of the guide protrusion 311 is provided with an arc-shaped guide surface 312. The guide protrusion 311 reduces the contact area between the upper end surface of the mixing hub 31 and the kitchen waste, thereby reducing the supporting force of the mixing hub 31 on the kitchen waste and further preventing the top from sealing off. The arc-shaped guide surface 312 guides the kitchen waste above the mixing hub 31 downwards, accelerating its fall.
[0032] Specifically, the distance H between the upper end face of the vertical stirring arm 35 and the upper end face of the stirring hub 31 is 1–50 mm. If the vertical stirring arm 35 is too high, the force on each stirring arm of the moving blade assembly will be uneven, while if the vertical stirring arm 35 is too low, it will not be able to cover the food waste. Preferably, the distance H between the upper end face of the vertical stirring arm 35 and the upper end face of the stirring hub 31 is 20–35 mm, thereby covering the food waste while reducing the height of the stirring hub 31.
[0033] Specifically, the mixing arm assembly includes at least one upper mixing arm 32, at least one middle crushing arm 33, and at least one lower crushing arm 34. The inner ends of the upper mixing arm 32, the middle crushing arm 33, and the lower crushing arm 34 are respectively spaced circumferentially on the outer side of the mixing hub 31. The cutting part 351 is formed on the upper part of the upper mixing arm 32 and adjacent to the mixing hub 31. The upper mixing arm 32 mixes the kitchen waste above, improving the mixing uniformity. The cutting part 351 is adjacent to the mixing hub 31 and close to the rotation axis of the moving blade assembly 3, reducing the rotation radius of the cutting part 351 and thus reducing the load on the motor. The middle crushing arm 33 and the lower crushing arm 34, while mixing, work with the fixed blade assembly to cut and grind, thereby crushing the kitchen waste and improving the crushing performance.
[0034] Specifically, the agitator arm assembly includes an upper agitator arm 32, a middle crushing arm 33, and two lower crushing arms 34. The inner ends of the two lower crushing arms 34 are formed in the lower part of the agitator hub 31, and the two lower crushing arms 34 are symmetrically arranged along the agitator hub 31. The inner end of the middle crushing arm 33 is formed in the middle of the agitator hub 31, and the inner end of the upper agitator arm 32 is formed in the upper part of the agitator hub 31. The upper agitator arm 32 and the middle crushing arm 33 are symmetrically arranged along the agitator hub 31, and both the upper agitator arm 32 and the middle crushing arm 33 are perpendicular to the adjacent lower crushing arms 34. There are grinding gaps between the lower part of the middle crushing arm 33 and the upper part of the fixed blade assembly, and between the upper part of the two lower crushing arms 34 and the lower part of the fixed blade assembly. The crushing efficiency is improved by using two symmetrical lower crushing arms 34. The upper agitator arm 32, the middle crushing arm 33, and the two lower crushing arms 34 are distributed at equal intervals along the circumference on the outer side of the agitator hub 31 to improve the dynamic balance of the moving blade assembly 3.
[0035] Specifically, the length of the vertical mixing arm 35 in the radial direction is less than the length of the middle crushing arm 33 and the lower crushing arm 34. When the dome is broken, or when food waste is first added, the vertical mixing arm 35 generates a small additional load due to its small mixing diameter. After the dome is broken, the food waste falls below the vertical mixing arm 35, so no additional load is generated.
[0036] Specifically, the lower crushing arm 34 includes an arc-shaped curved arm 341 and a crushing and cutting block 342. The inner end of the arc-shaped curved arm 341 is formed in the lower part of the stirring hub 31, and the crushing and cutting block 342 is formed in the outer end of the arc-shaped curved arm 341. The middle crushing arm 33 includes an upper cutting arm 331, a connecting arm 332, and a lower cutting arm 333. The inner end of the lower cutting arm 333 is formed in the middle of the stirring hub 31, the outer end of the lower cutting arm 333 is formed in the lower part of the connecting arm 332, and the inner end of the upper cutting arm 331 is formed in the upper part of the connecting arm 332, forming a "Z"-shaped middle crushing arm 33. The fixed blade assembly includes at least one fixed blade 4, which is provided with two cutting steps 41. The cutting steps 41 are used to form a grinding gap with the lower crushing arm 34 and the middle crushing arm 33. By increasing the overlap area between the fixed blade 4 and the lower crushing arm 34 and the middle crushing arm 33 through the cutting steps 41, the grinding surface is increased, thereby improving the crushing efficiency.
[0037] Specifically, the upper part of the crushing arm 33 is provided with a tumbling protrusion 334. The tumbling protrusion 334 tumbles the kitchen waste, especially the kitchen waste falling from above the mixing hub 31, to improve the uniformity of mixing.
[0038] The working principle of this utility model is as follows:
[0039] As the moving blade assembly 3 rotates, the upright stirring arm 35 rotates in a circle along the axis of the stirring hub 31, thereby separating the kitchen waste above and to the side of the stirring hub 31 to prevent the formation of a dome. The inner cutting slope 352 causes the kitchen waste above the stirring hub 31 to form a cone-shaped block that is smaller at the bottom and larger at the top, and it falls down along the arc-shaped guide surface 312. The dome-shaped part located outside the upright stirring arm 35 falls down along the outer cutting slope 353 and the inner wall of the barrel 1, thereby preventing or breaking the dome and avoiding the formation of a cap. Even if a dome is formed, it can be divided into cone-shaped blocks and annular blocks, which fall down separately to break the dome.
[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
