[0015] The beneficial effects of this invention are: 1. In use, the opening of the squeezing box is first aligned with the feeding mechanism. The feeding mechanism then feeds a fixed amount of kitchen waste into the squeezing box. The squeezing box, along with the kitchen waste, rotates towards the squeezing mechanism until its opening is aligned with it. The squeezing mechanism then squeezes the kitchen waste inside the box, squeezing out some of the water. This water flows through a filter layer to the outside of the squeezing box, where it is collected by a liquid receiving mechanism. Finally, the squeezing box, along with the kitchen waste, moves towards the transfer guide hood. The pressure chamber rotates counter-clockwise, thus throwing the kitchen waste inside the pressure chamber into the transfer guide hood. Then, the kitchen waste is initially dispersed by the dispersing mechanism. After being dispersed, the kitchen waste falls into the crushing and discharging mechanism, where it is crushed. During this process, the bacterial liquid adding mechanism adds a certain amount of bacterial liquid to the crushing and discharging mechanism to make the bacterial liquid mix more evenly with the crushed kitchen waste. Finally, the crushing and discharging mechanism discharges and transfers the processed kitchen waste.

[0016] 2. As the extrusion box rotates towards the transfer guide hood, it throws the kitchen waste inside the extrusion box into the transfer guide hood near the baffle plate. During this process, the kitchen waste impacts the surface of the rotating column, thus breaking it up (the extrusion mechanism only squeezes out some of the water in the kitchen waste, so the kitchen waste processed by the extrusion mechanism is still relatively loose). Some of the kitchen waste passes through the rotating column and falls down into the crushing and discharging mechanism. The crushing and discharging mechanism starts working to crush the kitchen waste that falls down. Then, multiple rotating columns rotate, conveying the kitchen waste on the rotating columns away from the baffle plate, causing the kitchen waste on the rotating columns to fall down one after another. During this process, the rotating columns also work with the crushing blocks to help disperse the passing kitchen waste.

[0017] 3. The size of the conveyor hood is smaller than that of the compression box. After the compression box has finished discharging the kitchen waste, it will rotate towards the conveyor hood. During this process, the side wall of the compression box will push against the conveyor hood and flip upward. When one side wall of the compression box passes the conveyor hood, one end of the conveyor hood will fall into the compression box under the action of gravity. At this time, the compression box stops rotating, and the sealing unit releases the blockage on the discharge channel. The kitchen waste located in the loading hood falls into the compression box under the action of gravity through the conveying rubber tube and the guide of the conveyor hood. After the compression box is loaded, the sealing unit seals the discharge channel. Then the compression box rotates towards the direction of the compression mechanism. During this process, the conveyor hood is pushed out of the compression box by the compression box, making it convenient to use. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Reference Figures 1-10 A kitchen waste crushing and composting device includes an outer shell 1. A compression box 2 is rotatably mounted on the inner wall of the outer shell 1. The upper end face of the compression box 2 is open. Multiple side passages 3 are opened on one side of the compression box 2. A filter layer 4 is fixed in each side passage 3. A compression mechanism and a liquid receiving mechanism are provided inside the outer shell 1 to cooperate with the compression box 2. A feeding mechanism is provided on the outer shell 1 to cooperate with the compression box 2. The feeding mechanism contains kitchen waste that can be crushed and composted. A transfer guide cover 5 is fixed on the inner wall of the outer shell 1. A baffle plate 6 is fixed on one side of the upper end face of the transfer guide cover 5. A dispersing mechanism is provided inside the transfer guide cover 5. A crushing and discharging mechanism and a bacterial liquid adding mechanism are also provided inside the outer shell 1. A drive box 7 is provided on the outer shell 1 to cooperate with the rotation of the compression box 2.

[0022] The drive box 7 is existing technology. The drive box 7 can drive the extrusion box 2 to rotate or keep the extrusion box 2 stationary.

[0023] In use, the opening of the squeezing box 2 is first aligned with the feeding mechanism. The feeding mechanism then feeds a fixed amount of kitchen waste into the squeezing box 2. The squeezing box 2, carrying the kitchen waste, rotates towards the squeezing mechanism until its opening is aligned with it. The squeezing mechanism then squeezes the kitchen waste inside the squeezing box 2, squeezing out some of the water. This water flows through the filter layer 4 to the outside of the squeezing box 2, where it is collected by a liquid receiving mechanism. Finally, the squeezing box 2, carrying the kitchen waste, moves towards the transfer guide. The direction of the hood 5 is rotated (the direction of rotation of the squeezing box 2 is counterclockwise), thereby throwing the kitchen waste inside the squeezing box 2 into the transfer guide hood 5. Then, the kitchen waste is initially dispersed by the dispersing mechanism. After being dispersed, the kitchen waste will fall into the crushing and discharging mechanism. The crushing and discharging mechanism crushes the kitchen waste. During this process, the bacterial liquid adding mechanism adds a certain amount of bacterial liquid into the crushing and discharging mechanism to make the bacterial liquid mix more evenly with the crushed kitchen waste. Then, the crushing and discharging mechanism discharges and transfers the processed kitchen waste.

[0024] The dispersing mechanism includes multiple rotating columns 8 rotatably mounted on the inner wall of the transfer guide hood 5, and multiple crushing blocks 9 are fixed on the outer surface of adjacent rotating columns 8.

[0025] As the squeezing box 2 rotates toward the transfer guide hood 5, it throws the kitchen waste inside the squeezing box 2 into the transfer guide hood 5 and near the baffle plate 6. During this process, the kitchen waste will hit the surface of the rotating column 8, thus breaking it up (the above-mentioned squeezing mechanism only squeezes out some of the water contained in the kitchen waste, so the kitchen waste processed by the squeezing mechanism is still relatively loose). Some of the kitchen waste passes through the rotating column 8 and falls down into the crushing and discharging mechanism. The crushing and discharging mechanism starts to work to crush the kitchen waste that falls down one after another. Then, multiple rotating columns 8 rotate, conveying the kitchen waste on the rotating columns 8 toward the direction away from the baffle plate 6, so that the kitchen waste on the rotating columns 8 can fall down one after another. During this process, the rotating columns 8 also work with the crushing blocks 9 to help disperse the kitchen waste that passes through.

[0026] Multiple rotating columns 8 are fixed with a connecting shaft 10 at one end. The end of each connecting shaft 10 rotates through to the outside of the outer shell 1. A chain drive unit 11 is provided between two adjacent connecting shafts 10. The chain drive unit 11 is existing technology. The other end of one of the rotating columns 8 is fixed with a connecting shaft 2 12. The end of the connecting shaft 2 12 rotates through to the outside of the outer shell 1 and is fixedly fitted with a gear ring 50. A connecting shaft 3 51 is rotatably provided on the outer wall of the outer shell 1. A small sprocket 52 and a gear ring 2 53 are fixedly fitted on the outer surface of the connecting shaft 3 51. The gear ring 2 53 meshes with the gear ring 1 50. Connecting shaft 4 54 is fixed on both sides of the extrusion box 2. The end of the corresponding connecting shaft 4 54 rotates through the outer shell 1 and is fixedly fitted with a large sprocket 55. A chain body 56 is fitted between the large sprocket 55 and the small sprocket 52. The drive box 7 drives another connecting shaft 4 54 to rotate.

[0027] After the squeezing box 2 finishes discharging the kitchen waste, it will continue to rotate until the opening end of the squeezing box 2 is aligned with the feeding mechanism again. During this process, the squeezing box 2 drives the connecting shaft 4 54 and the large sprocket 55 to rotate forward together, thereby driving the small sprocket 52, the connecting shaft 3 51 and the gear ring 2 53 to rotate forward together. Since the gear ring 2 53 is suitable for meshing with the gear ring 1 50, it drives the gear ring 1 50 and the connecting shaft 2 12 to rotate in the opposite direction, thereby driving the corresponding rotating column 8 and the connecting shaft 1 10 to rotate together. Under the action of multiple chain drive units 11, multiple connecting shafts 1 10 and rotating column 8 are caused to rotate together, conveying the kitchen waste located on the rotating column 8 in a direction away from the baffle plate 6.

[0028] The feeding mechanism includes a feeding cover 17 fixedly penetrating the upper end face of the outer shell 1. A discharge channel 18 is provided on the lower end face of the feeding cover 17. A conveying rubber tube 19 for use with the discharge channel 18 is fixedly connected to the lower end face of the feeding cover 17. A conveying cover 20 is rotatably provided on the inner wall of the outer shell 1. One end of the conveying cover 20 is connected to the end of the conveying rubber tube 19. A limiting plate 21 for use with the conveying cover 20 is fixed on the inner wall of the outer shell 1. A sealing unit for use with the discharge channel 18 is provided on the feeding cover 17.

[0029] The size of the conveying cover 20 is smaller than that of the squeezing box 2. After the squeezing box 2 has finished discharging the kitchen waste, it will rotate toward the conveying cover 20. During this process, the side wall of the squeezing box 2 will press against the conveying cover 20 and flip upward. When one side wall of the squeezing box 2 passes the conveying cover 20, one end of the conveying cover 20 will fall into the squeezing box 2 under the action of gravity. At this time, the squeezing box 2 stops rotating, and the sealing unit releases the seal on the discharge channel 18. The kitchen waste located in the loading cover 17 falls into the squeezing box 2 under the action of gravity through the conveying rubber tube 19 and the conveying cover 20. After the squeezing box 2 is loaded, the sealing unit seals the discharge channel 18. Then the squeezing box 2 rotates toward the squeezing mechanism. During this process, the conveying cover 20 is pushed out of the squeezing box 2 by the squeezing box 2, which is convenient to use.

[0030] The sealing unit includes a pull-out groove on one side of the feeding hood 17, which extends through the unloading channel 18. A pull-out plate 22 is movably arranged inside the pull-out groove. A connecting plate 23 is fixed to one end of the pull-out plate 22. A mounting bracket 24 is fixed to the upper end face of the outer shell 1. Two hydraulic rods 25 are fixedly arranged through the side wall of the mounting bracket 24. The ends of the extension and retraction ends of the hydraulic rods 25 are fixedly connected to the connecting plate 23.

[0031] In the initial state, the telescopic end of the hydraulic rod 25 is in an extended state, thereby blocking the discharge channel 18 by the pull plate 22. When the discharge channel 18 needs to discharge material, the telescopic end of the hydraulic rod 25 retracts, causing the connecting plate 23 and the pull plate 22 to move away from the loading cover 17, thereby causing the pull plate 22 to release the blockage of the discharge channel 18.

[0032] The extrusion mechanism includes a hydraulic rod 26 that is fixedly inserted through the mounting bracket 24. An extrusion plate 27 is fixed to the end of the telescopic end of the hydraulic rod 26, and the upper end of the hydraulic rod 26 penetrates the outer shell 1.

[0033] In the initial state, the telescopic end of the hydraulic rod 26 is in a retracted state. When it is necessary to squeeze the kitchen waste in the squeezing box 2, the telescopic end of the hydraulic rod 26 extends, pushing the squeezing plate 27 downward.

[0034] The liquid receiving mechanism includes a liquid receiving box 28 movably disposed within the outer casing 1. The upper end of the liquid receiving box 28 is open, and a notch is provided on one side of the liquid receiving box 28. A rubber guide strip 29 is fixed in the notch. A drain hose 30 is connected to the lower end face of the liquid receiving box 28. One end of the drain hose 30 extends through to the outside of the outer casing 1 and is connected to an external liquid collection tank. A drive unit is provided inside the outer casing 1 to cooperate with the translation of the liquid receiving box 28.

[0035] In the initial state, the liquid receiving box 28 is located away from the extrusion box 2, so as to avoid affecting the loading and rotation of the extrusion box 2. After the opening end of the extrusion box 2 rotates towards the extrusion plate 27, the liquid receiving box 28 is driven by the drive unit to abut against the side wall of the extrusion box 2, so that the liquid receiving box 28, together with the rubber guide strip 29, collects the liquid flowing out from the side passage 3 of the extrusion box 2.

[0036] The drive unit includes a second mounting bracket 31 fixed to the inner wall of the outer casing 1. An electric push rod 32 is fixedly and through the side wall of the second mounting bracket 31. The end of the telescopic end of the electric push rod 32 is fixedly connected to the side wall of the liquid receiving box 28. A plurality of guide posts 34 are fixed on one side of the liquid receiving box 28, and each guide post 34 is movable through the second mounting bracket 31.

[0037] In the initial state, the telescopic end of the electric actuator 32 is in the retracted state.

[0038] The bacterial liquid addition mechanism includes an annular tube 35 fixed to the lower surface of the transfer guide cover 5. Multiple spray nozzles 36 are connected to the lower surface of the annular tube 35. A liquid supply hose 37 is connected to the outer surface of the annular tube 35. The liquid supply hose 37 penetrates the outer shell 1. One end of the liquid supply hose 37 is connected to an external bacterial liquid supply unit. The bacterial liquid supply unit is existing technology.

[0039] As the kitchen waste in the transfer guide hood 5 falls into the crushing and discharging mechanism, the crushing and discharging mechanism crushes the falling kitchen waste. During this process, the bacterial liquid supply unit, together with the liquid supply hose 37, the annular pipe 35 and multiple spray nozzles 36, adds a small amount of bacterial liquid to the crushing and discharging mechanism in batches to promote the bacterial liquid to mix evenly with the crushed kitchen waste.

[0040] The crushing and discharging mechanism includes two electric guide rails 38 symmetrically fixed to the inner wall of the outer shell 1. A circular frame 39 is movably arranged between the two electric guide rails 38. A left crushing barrel 40 and a right crushing barrel 41 are symmetrically rotatably arranged on the inner wall of the circular frame 39. A left discharge channel 42 and a right discharge channel 43 are opened at the inner bottom of the outer shell 1. A receiving frame 44 is provided below the left discharge channel 42 and the right discharge channel 43. Crushing blade groups are rotatably arranged inside the left crushing barrel 40 and the right crushing barrel 41. A working motor for the crushing blade group is fixed at the bottom of the left crushing barrel 40 and the right crushing barrel 41. A drive component for the rotation of the left crushing barrel 40 and the right crushing barrel 41 is respectively provided on the circular frame 39. The above content belongs to the prior art and is a conventional technical means in this field.

[0041] In operation, the right-side crushing bin 41 is initially positioned below the transfer guide hood 5. After the compression box 2 throws kitchen waste onto the transfer guide hood 5, the compression box 2 continues to rotate towards the feeding mechanism. At this time, the right-side crushing bin 41 receives and crushes the kitchen waste falling from the transfer guide hood 5. When the compression box 2 is fully loaded and rotates to below the compression mechanism, the electric guide rail 38 drives the return frame 39 to move the left-side crushing bin 40 and the right-side crushing bin 41 to the right until the right-side crushing bin 41 moves above the right-side discharge chute 43. At this time, the left-side crushing bin 40 moves to below the transfer guide hood 5, receiving the subsequent kitchen waste falling from the right side. The crushing bucket 41 pours the crushed and mixed kitchen waste into the receiving frame 44 located below. After the left crushing bucket 40 finishes receiving the waste, the rotating frame 39 moves the left crushing bucket 40 and the right crushing bucket 41 to the left until the left crushing bucket 40 is above the left discharge chute 42. The right crushing bucket 41 then moves to the bottom of the transfer guide hood 5. Then the left crushing bucket 40 pours the crushed and mixed kitchen waste into the receiving frame 44 located below. The process is repeated according to the above working principle. During this process, the staff removes the filled receiving frame 44 and replaces it with an empty one. Finally, the staff places the filled receiving frames 44 in the external composting chamber for composting and fermentation.

[0042] In use, the opening of the squeezing box 2 is first aligned with the feeding mechanism, which then feeds a fixed amount of kitchen waste into the squeezing box 2. The squeezing box 2, carrying the kitchen waste, rotates towards the squeezing mechanism until its opening is aligned with it. The squeezing mechanism then squeezes the kitchen waste inside the squeezing box 2, squeezing out some of the water. This water flows through the filter layer 4 to the outside of the squeezing box 2, where it is collected by a liquid receiving mechanism. Finally, the squeezing box 2, carrying the kitchen waste, moves towards the transfer guide hood. The compression box 2 rotates counterclockwise (5), thus throwing the kitchen waste inside the compression box 2 into the transfer guide hood 5. Then, the kitchen waste is initially dispersed by the dispersing mechanism. After being dispersed, the kitchen waste falls into the crushing and discharging mechanism. The crushing and discharging mechanism crushes the kitchen waste. During this process, the bacterial liquid adding mechanism adds a certain amount of bacterial liquid to the crushing and discharging mechanism to make the bacterial liquid mix more evenly with the crushed kitchen waste. Then, the crushing and discharging mechanism discharges and transfers the processed kitchen waste. As the extrusion box 2 rotates toward the transfer guide hood 5, it throws the kitchen waste inside the extrusion box 2 into the transfer guide hood 5 and near the baffle plate 6. During this process, the kitchen waste will hit the surface of the rotating column 8, thus breaking up the kitchen waste (the extrusion mechanism only squeezes out some of the water contained in the kitchen waste, so the kitchen waste processed by the extrusion mechanism is still relatively loose). Some of the kitchen waste passes through the rotating column 8 and falls down into the crushing and discharging mechanism. The crushing and discharging mechanism starts to work to crush the kitchen waste that falls down one after another. Then, multiple rotating columns 8 rotate, conveying the kitchen waste on the rotating columns 8 toward the direction away from the baffle plate 6, so that the kitchen waste on the rotating columns 8 can fall down one after another. During this process, the rotating column 8 also works with the crushing block 9 to help disperse the kitchen waste that passes through. In operation, the right-side crushing bin 41 is initially positioned below the transfer guide hood 5. After the compression box 2 throws kitchen waste onto the transfer guide hood 5, the compression box 2 continues to rotate towards the feeding mechanism. At this time, the right-side crushing bin 41 receives and crushes the kitchen waste falling from the transfer guide hood 5. When the compression box 2 is fully loaded and rotates to below the compression mechanism, the electric guide rail 38 drives the return frame 39 to move the left-side crushing bin 40 and the right-side crushing bin 41 to the right until the right-side crushing bin 41 moves above the right-side discharge chute 43. At this time, the left-side crushing bin 40 moves to below the transfer guide hood 5, receiving the subsequent kitchen waste falling from the right side. The crushing bucket 41 pours the crushed and mixed kitchen waste into the receiving frame 44 located below. After the left crushing bucket 40 finishes receiving the waste, the rotating frame 39 moves the left crushing bucket 40 and the right crushing bucket 41 to the left until the left crushing bucket 40 is above the left discharge chute 42. The right crushing bucket 41 then moves to the bottom of the transfer guide hood 5. Then the left crushing bucket 40 pours the crushed and mixed kitchen waste into the receiving frame 44 located below. The process is repeated according to the above working principle. During this process, the staff removes the filled receiving frame 44 and replaces it with an empty one. Finally, the staff places the filled receiving frames 44 in the external composting chamber for composting and fermentation.

However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
