[0002] Urban organic waste refers to perishable and biodegradable waste generated in urban life, mainly including kitchen waste, garden waste, etc. These wastes are rich in organic matter. If properly handled, they can be converted into valuable resources such as fertilizers and energy, which will help promote the development of the circular economy. However, if improperly handled, they may cause environmental pollution and health problems. Therefore, scientific management and effective utilization of urban organic waste are of great significance to promoting sustainable urban development.

[0003] Among them, the fermentation and composting of urban organic waste is an environmentally friendly and resource-saving treatment method. It uses the biochemical action of microorganisms to decompose and mature the organic matter in organic waste under artificial control conditions and convert it into stable humus-like substances. This method can not only convert organic waste into useful fertilizers or soil conditioners, realize the resource utilization of waste, but also reduce the pollution of waste to the environment, promote the improvement of soil fertility and the growth of crops.

[0004] At present, when organic waste is fermented and composted, the collected organic waste must first be pre-processed, such as crushing and mixing, to facilitate the decomposition of microorganisms. However, the existing equipment has a single stirring direction and a fixed stirring range, which makes it impossible for the equipment to reach organic waste in remote locations, resulting in insufficient crushing of the organic waste and insufficient mixing with the fermentation liquid, which leads to unsatisfactory composting effect of the organic waste and is not convenient for practical use.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] See also Figure 1-7 As shown in the figure, this embodiment provides a kind of urban organic waste fermentation composting treatment device, such as Figure 1As shown, it includes a garbage storage container 1, and a gathering, mixing and stirring mechanism 2 is rotatably installed inside the garbage storage container 1. When working, the gathering, mixing and stirring mechanism 2 can gather the garbage in the garbage storage container 1.

[0023] Combination Figure 2 and Figure 5-6 As shown, the gathering, mixing and stirring mechanism 2 includes a rotating drive shaft 21 rotatably installed inside the garbage storage container 1, and one end of the rotating drive shaft 21 is rotatably sleeved with a reciprocating threaded sleeve rod 24 rotatably connected to the garbage storage container 1.

[0024] Specifically, a reciprocating threaded sleeve 24 can be sleeved on the outer wall of one end of the rotating drive shaft 21, a driving motor is provided at one end of the reciprocating threaded sleeve 24, and a driving motor is provided at the other end of the rotating drive shaft 21. The two driving motors can respectively drive the reciprocating threaded sleeve 24 and the rotating drive shaft 21 to rotate in the garbage storage container 1, and the rotating drive shaft 21 also rotates in the reciprocating threaded sleeve 24.

[0025] The first eccentric crushing disk 22 and the second eccentric crushing disk 23 are fixedly connected to the rotating drive shaft 21 near the reciprocating threaded sleeve 24 , and a driving sleeve 25 is meshed on the reciprocating threaded sleeve 24 . A plurality of first connecting support frames 26 are hinged on the driving sleeve 25 .

[0026] Specifically, a rotatable slip ring may be sleeved on the driving sleeve 25 , and the plurality of first coupling support frames 26 are hinged on the rotatable slip ring, so that the plurality of first coupling support frames 26 can rotate on the driving sleeve 25 .

[0027] A plurality of second connection support frames 27 are rotatably hingedly connected to a side of the rotary drive shaft 21 away from the reciprocating threaded sleeve 24. Specifically, when the rotary drive shaft 21 rotates, the plurality of second connection support frames 27 can be driven to rotate.

[0028] A directional stirring pressure piece 28 is hinged between each of the first connecting support frame 26 and the second connecting support frame 27. When the reciprocating threaded sleeve 24 rotates, it can drive the directional stirring pressure piece 28 to perform rotational cutting in the garbage storage container 1, and can also drive the directional stirring pressure piece 28 to reciprocately gather and disperse toward the positions of the first eccentric crushing disk 22 and the second eccentric crushing disk 23.

[0029] It can be understood that in actual use, the reciprocating threaded sleeve 24 and the rotating drive shaft 21 start to rotate respectively through the driving motor, and the rotating rotating drive shaft 21 first drives the first eccentric crushing disk 22 and the second eccentric crushing disk 23 to rotate, and the rotating reciprocating threaded sleeve 24 drives the driving sleeve 25 to rotate and reciprocate on its outer wall, thereby driving the corresponding multiple first connecting support frames 26 and multiple second connecting support frames 27 to change their inclination angles synchronously; when the driving sleeve 25 translates toward the direction of the reciprocating threaded sleeve 24, the multiple first connecting support frames 26 and the multiple second connecting support frames 27 are all inclined toward the rotating drive shaft 21, thereby driving the multiple directional stirring tablets 28 The first eccentric crushing disk 22 and the second eccentric crushing disk 23 are gathered together. When the driving sleeve 25 is translated toward the direction of the second connecting support frame 27, the plurality of first connecting support frames 26 and the plurality of second connecting support frames 27 are adjusted toward the outer peripheral direction of the rotating driving shaft 21, thereby driving the plurality of directional stirring pressing sheets 28 to disperse in the direction away from the first eccentric crushing disk 22 and the second eccentric crushing disk 23, so that the directional stirring pressing sheets 28 are reciprocatedly gathered and dispersed toward the positions of the first eccentric crushing disk 22 and the second eccentric crushing disk 23. In this process, the garbage in the garbage storage container 1 will be continuously pushed toward the rotating first eccentric crushing disk 22 and the second eccentric crushing disk 23 for deep crushing;

[0030] The rotating rotary drive shaft 21 will also drive the directional stirring press plate 28 to rotate through multiple second connecting support frames 27, thereby realizing preliminary cutting and stirring of the garbage in the garbage storage container 1; the above technical scheme not only stirs and preliminarily cuts the garbage in the garbage storage container 1 through the directional stirring press plate 28, but also gathers the garbage to the position of the first eccentric crushing disk 22 and the second eccentric crushing disk 23 through the directional stirring press plate 28, so that it is deeply crushed by the first eccentric crushing disk 22 and the second eccentric crushing disk 23, thereby making the garbage crushing and mixing processing efficiency stronger, and then it can be more fully mixed with the garbage fermentation material, avoiding the traditional method of only being able to rotate and stir in the inner cavity of the garbage storage container 1, resulting in the garbage in the dead corner cannot be close to the center, and then there are problems of incomplete damage and uneven stirring, which affects the subsequent actual use.

[0031] Further, wherein, referring to Figure 2 As shown, the number of the second eccentric crushing disks 23 is set to two, and the two second eccentric crushing disks 23 are symmetrically arranged with respect to the vertical center line of the first eccentric crushing disk 22, the off-circle center points of the two second eccentric crushing disks 23 are arranged near the bottom position of the second eccentric crushing disk 23, and the off-circle center point of the first eccentric crushing disk 22 is arranged near the top position of the first eccentric crushing disk 22.

[0032] Specifically, the purpose of such a configuration is that when the garbage is brought closer to the first eccentric crushing disk 22 and the second eccentric crushing disk 23, when the rotating drive shaft 21 drives the first eccentric crushing disk 22 and the two second eccentric crushing disks 23 to rotate and cut the damaged garbage, the first eccentric crushing disk 22 and the second eccentric crushing disk 23 have different contact ranges with the garbage, thereby making the garbage crushing effect better and more comprehensive.

[0033] It should be noted that although the above technical solution can handle most of the garbage in the garbage storage container 1, a small amount of garbage may still remain at the corners of the garbage storage container 1. Therefore, in order to further handle the mixing dead corners and improve the efficiency, a specific pushing and mixing liquid mechanism 3 can be designed, as shown below:

[0034] Furthermore, combined with Figure 3 and Figure 7 As shown, it also includes a pushing and mixing liquid mechanism 3, which includes a plurality of squeezing and pushing plates 31 slidably installed inside the garbage storage container 1, and a hollow sleeve 32 arranged vertically therewith is fixedly installed inside the plurality of squeezing and pushing plates 31.

[0035] Specifically, the hollow sleeve 32 is arranged perpendicular to the extrusion and pushing plate 31 .

[0036] The inner cavities of the plurality of hollow sleeves 32 are all plugged with piston rods 33 fixedly connected to the garbage storage container 1, and a flexible connecting pipe 34 is provided between the two hollow sleeves 32 arranged on each of the extrusion and pushing plates 31. Specifically, the fermentation liquid can be replenished from the outside to the space between each two hollow sleeves 32 in a timely manner through the flexible connecting pipe 34.

[0037] At the same time, refer to Figure 3 and Figure 5 As shown, two push drive frames 35 extending into the inner cavity of the garbage storage container 1 and fixedly connected to the extrusion push plate 31 are slidably installed on the outer wall of the garbage storage container 1, and a connecting bracket 36 is fixedly connected between the two pushing drive frames 35, and a spring member 37 fixedly connected to the garbage storage container 1 is fixedly installed on the outer wall of the connecting bracket 36.

[0038] Specifically, the purpose of such a configuration is to enable one of the push drive frames 35 to move stably by driving the push drive frame 35 on the other side through the connecting bracket 36 when one of the push drive frames 35 moves.

[0039] It can be understood that when in use, the inner cavity of the hollow sleeve 32 is filled with fermentation liquid. When the squeezing and pushing plate 31 is made to slide as a whole inside the garbage storage container 1, on the one hand, the garbage at the corners of the inner cavity of the garbage storage container 1 can be pushed back and forth toward the center by the moving multiple squeezing and pushing plates 31. On the other hand, the moving hollow sleeve 32 reciprocates on the outer wall of the piston rod 33, so that the piston rod 33 can push the fermentation liquid in the inner cavity of the hollow sleeve 32 to spray outward, so that the fermentation liquid can be sprayed on the surface of the garbage placed in the inner cavity of the garbage storage container 1 from multiple places.

[0040] Furthermore, the number of the squeezing and pushing plates 31 is set to at least four, and every two of the squeezing and pushing plates 31 are symmetrically arranged about the center line of the garbage storage container 1, and the number of the hollow sleeves 32 arranged on each of the squeezing and pushing plates 31 is set to two, and the two hollow sleeves 32 are symmetrically arranged about the horizontal center line of the squeezing and pushing plates 31.

[0041] Specifically, the purpose of such a setting is to enable multiple extrusion pushing plates 31 to push the small amount of garbage remaining at the corners of the garbage storage container 1 to the outer periphery of the gathering, mixing and stirring mechanism 2 at equal intervals. At the same time, through the setting of the symmetrical hollow sleeve 32, the inside and surface of the garbage can be sprayed with fermentation liquid, so that the contact between the garbage and the fermentation liquid is more complete.

[0042] More preferably, referring to Figure 3-4 As shown, it also includes a power coupling output mechanism 4, which includes a supporting rotating shaft 41 rotatably installed on one side of the garbage storage container 1, the outer wall of the supporting rotating shaft 41 is fixedly connected with a guide pillar 42, the outer wall of the guide pillar 42 is fixedly connected with an oblique guide slide rail 43, the outer wall of the oblique guide slide rail 43 is slidably connected with a directional slider 44 fixedly connected to the pushing drive frame 35, and the outer wall of the supporting rotating shaft 41 is fixedly installed with a secondary transmission gear 45.

[0043] Specifically, in actual use, by rotating the supporting rotating shaft 41 and the guide pillar 42 as a whole, the directional slider 44 can slide along the outer track of the oblique guide rail 43, thereby driving the secondary transmission gear 45 to slide as a whole on one side of the garbage storage container 1, and then the end extending into the inner cavity of the garbage storage container 1 synchronously drives the corresponding extrusion and pushing plate 31 to move as a whole, and then pushes the garbage at the side position inside the garbage storage container 1 for processing.

[0044] Combination Figure 1-2As shown, a main transmission gear 29 is fixedly mounted on the outer wall of the reciprocating threaded sleeve 24 , and a power transmission belt 46 is meshed between the outer walls of the main transmission gear 29 and the secondary transmission gear 45 .

[0045] Specifically, when in use, by starting the reciprocating threaded sleeve 24 to drive multiple directional stirring plates 28 to move toward the rotating drive shaft 21, the rotating main transmission gear 29 drives the power transmission belt 46 to move on the outer wall of the secondary transmission gear 45, thereby driving the supporting rotating shaft 41 to rotate as a whole, and then the guide pillar 42 rotates as a whole, so that the directional slider 44 drives the pushing drive frame 35 to move horizontally back and forth along the outer trajectory of the oblique guide slide rail 43 as a whole, thereby synchronously driving multiple extrusion pushing plates 31 to reciprocate in the inner cavity of the garbage storage container 1, so as to push the garbage at the side position of the inner cavity of the garbage storage container 1 to the gathering, mixing and stirring mechanism 2, so as to avoid the problem that the garbage accumulates in the dead corner inside the garbage storage container 1 and cannot be crushed, stirred and mixed.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
