Detailed Implementation

[0024] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Please see Figures 1 to 7 The present invention preferably provides the following technical solution: an anti-tangling kitchen waste pulverizing device, comprising: a pulverizing tank 1112, a wastewater storage tank detachably installed below the pulverizing tank 1112; and a filter plate assembly disposed between the pulverizing tank 1112 and the wastewater storage tank for solid-liquid separation of kitchen waste; further comprising a cover structure detachably installed on the top of the pulverizing tank 1112, a gear drive assembly mounted on the cover structure, the actuating end of the gear drive assembly extending downward through the cover structure and extending to a connecting rod 312 and an outer sleeve 313; and a first cutter structure and a second cutter structure respectively mounted on the connecting rod 312 and the outer sleeve 313 and arranged alternately, which, when the gear drive assembly is running, drive the first cutter structure and the second cutter structure to run in opposite directions.

[0026] The main body of the pulverizing device described in this application consists of a detachable cover structure (upper, middle, and lower sections), a pulverizing tank 1112, and a wastewater storage tank. Figure 1 , 2 As shown in Figure 3, the gear drive assembly installed on the cover structure can indirectly drive the first cutter structure and the second cutter structure respectively set on the connecting rod 312 and the outer sleeve 313 to rotate in different directions in the clockwise and counterclockwise directions by driving the connecting rod 312 and the outer sleeve 313 at its execution end. This crushing method in opposite directions has a series of significant advantages compared with unidirectional crushing or hammer crushing, especially for processing materials such as kitchen waste that are complex in composition, have high moisture content, and are tough.

[0027] First, the first and second cutting blades, rotating in opposite directions, generate a powerful shearing force, cutting and tearing the waste like scissors. This mechanism is very effective for both tough materials (such as fibers, fruit peels, vegetable stems and leaves, and plastic bags) and soft materials (such as food scraps and fruit pulp), and can significantly improve the crushing effect.

[0028] Secondly, the fibers and film bags in kitchen waste are difficult to break by impact or compression, but the shearing force of the reverse rotation can effectively cut them, reducing downtime caused by entanglement;

[0029] Finally, reverse shearing crushing can produce more uniform and finer particles, which is crucial for subsequent processing (such as anaerobic digestion and aerobic composting) and can significantly improve reaction speed and efficiency. Therefore, this application, through the staggered design of the first cutter structure and the second cutter structure, combined with the structural characteristics of the gear drive assembly, can achieve different cutting directions of the first cutter structure and the second cutter structure, which not only improves the crushing effect and efficiency, but also reduces the occurrence of machine downtime caused by soft fibers entangled in the blades.

[0030] In addition, the filter plate assembly installed between the pulverizing tank 1112 and the wastewater storage tank, combined with Figure 3 , 4 As shown, during the crushing process inside the crushing tank 1112, the filter plate assembly can separate the solid and liquid components of the crushed waste. Since the original moisture content of kitchen waste is usually above 70%-90%, which is much higher than the ideal moisture content for composting (50%-60%), separating most of the free water can make the moisture content of the solid material closer to the range required for composting, avoiding problems such as anaerobic digestion, odor, slow heating, and material caking caused by excessive moisture. The design of the filter plate assembly can optimize the subsequent processing technology and improve efficiency.

[0031] Furthermore, the wastewater storage tank includes a recycling tank body 1111, a stepped portion 211 at the top of the recycling tank body 1111, and a threaded groove 212 formed on the side wall of the stepped portion 211; it also includes an external threaded sleeve 213 fixed to the bottom of the crushing tank 1112 and threadedly connected to the threaded groove 212; furthermore, the filter plate assembly includes a sealing ring 214 disposed inside the stepped portion 211; and a filter plate body 215 disposed on the sealing ring 214 for solid-liquid separation of kitchen waste.

[0032] Combination Figure 3 , 4 As shown, the stepped portion 211 fixed at the top of the recycling tank 1111 is adapted to overlap with the outer threaded sleeve 213 fixed at the bottom of the crushing tank 1112. At the same time, the threaded groove 212 opened on the side wall of the stepped portion 211 is threadedly connected to the outer threaded sleeve 213 to realize the detachable installation of the crushing tank 1112 and the recycling tank 1111. The sealing ring 214 installed inside the stepped portion 211 and the filter plate 215 installed on the sealing ring 214 can be placed between the crushing tank 1112 and the recycling tank 1111 when the threaded groove 212 and the outer threaded sleeve 213 are threadedly connected, so as to realize the solid-liquid separation operation of the waste inside the crushing tank 1112.

[0033] Furthermore, the cover structure includes a top cover 112 that fits and overlaps with the top of the crushing tank 1112, and a snap-fit ​​structure that is annularly disposed between the crushing tank 1112 and the top cover 112 for tight installation of the two; each snap-fit ​​structure includes a mounting base 216 fixed near the top side wall of the crushing tank 1112, on which a buckle 217 is rotatably mounted; and a hook 218 fixed to the edge of the top cover 112 and fitted and fastened to the buckle 217.

[0034] Combination Figure 4 As shown, the top cover 112 and the crushing tank 1112 are detachably installed through several snap-fit ​​structures. When the buckle 217 of each snap-fit ​​structure is engaged or disengaged from its corresponding hook 218, the installation or disassembly of the top cover 112 and the crushing tank 1112 can be achieved.

[0035] Furthermore, the top of the top cover 112 is also provided with an opening, and a feed hopper 113 is fixed at the top of the opening for feeding the crushing tank 1112.

[0036] Furthermore, the gear drive assembly includes an inverted frame 311 fixed to the top of the top cover 112, wherein one end of the connecting rod 312 is rotatably mounted to the top of the inverted frame 311 and fixed with a first transmission tooth 322, and the other end of the connecting rod 312 passes through through holes respectively opened at the bottom of the inverted frame 311 and the middle part of the top cover 112 and extends with a first cutter structure; the connecting rod 312 is sleeved on the connecting rod 312 and rotatably mounted with the through hole, and one end of the connecting rod 312 is fixed with a second transmission tooth 325 symmetrically distributed with the first transmission tooth 322, and the other end of the connecting rod 312 extends into the crushing tank 1112 and connects with the second cutter structure; and a motor 323 is disposed in the middle of the inverted frame 311, and the output shaft of the motor 323 passes through the inverted frame 311 and is fixed with a drive tooth 324, wherein the first transmission tooth 322 and the second transmission tooth 325 respectively mesh on both sides of the drive tooth 324 and are symmetrically distributed.

[0037] Combination Figure 5 , 6 As shown in Figure 7, the connecting rod 312 and the outer sleeve 313 are distributed inside and outside. One end of the connecting rod 312 is fixed with a first transmission tooth 322, and the other end extends into the crushing tank 1112 and connects to the first cutter structure. One end of the outer sleeve 313 is fixed with a second transmission tooth 325, and the other end extends into the second cutter structure. The drive tooth 324 fixed at the output end of the motor 323 meshes with the symmetrically distributed first transmission tooth 322 and second transmission tooth 325, thus combining... Figure 7 As shown, since the first transmission gear 322 and the second transmission gear 325 mesh on both sides of the drive gear 324, when the drive gear 324 rotates, the first transmission gear 322 and the second transmission gear 325 run in opposite directions, thereby enabling the first cutter structure on the connecting rod 312 and the second cutter structure on the outer sleeve 313 to achieve staggered and opposite-direction movements.

[0038] Furthermore, the first cutter structure includes a horizontal plate 314 fixed in a ring to the side wall near the bottom end of the connecting rod 312, and a vertical plate 315 fixed to the outer end of each horizontal plate 314; and a plurality of first cutter bodies 316 installed on the inner side of the vertical plate 315, wherein when the connecting rod 312 rotates, the plurality of first cutter bodies 316 cut the waste; further, the second cutter structure includes an assembly ring 318 fixed to the bottom of the outer sleeve 313; an assembly plate 319 fixed in a ring to the bottom of the assembly ring 318 and placed on the outer periphery of the connecting rod 312, wherein a plurality of second cutter bodies 320 are fixed on the outer side of each assembly plate 319, wherein the plurality of second cutter bodies 320 and their opposite plurality of first cutter bodies 316 are arranged alternately.

[0039] Combination Figure 5 , 6 As shown in Figure 7, the connecting rod 312 passes through the bottom of the outer sleeve 313 and is arranged in a ring with a horizontal plate 314 and a vertical plate 315. These plates are distributed on the outside of the assembly plate 319, which is fixed in a ring at the bottom of the outer sleeve 313 by an assembly ring 318. Each assembly plate 319 and its corresponding vertical plate 315 are respectively equipped with a second cutter body 320 and a first cutter body 316 that are staggered. Therefore, when the connecting rod 312 and the outer sleeve 313 move in opposite directions, the first cutter body 316 and the second cutter body 320 can perform reverse cutting operations, ensuring crushing effect and efficiency.

[0040] Furthermore, a first arc-shaped cutter 317 is installed on the inner sidewall near the top of each vertical plate 315; furthermore, a second arc-shaped cutter 321 is also fixed in a ring around the outer periphery of the assembly ring 318, and the second arc-shaped cutter 321 and the first arc-shaped cutter 317 are arranged alternately vertically.
