Detailed Implementation

[0025] 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.

[0026] Example 1

[0027] Please see Figures 1 to 6The present invention preferably provides the following technical solution: a kitchen waste compression and packaging device, comprising: an assembly support; a crushing cylinder assembly and a spiral extrusion roller assembly disposed above and below the assembly support and interconnected thereto, for crushing kitchen waste and extruding the crushed waste; wherein, the spiral extrusion roller assembly includes a spiral conveying pipe 311, with an inlet and an outlet respectively opened at both ends of the spiral conveying pipe 311, wherein the inner diameter of the spiral conveying pipe 311 decreases progressively along the direction of kitchen waste conveying; a bolt conveying roller 312 disposed inside the spiral conveying pipe 311; and a plurality of through holes 314 opened near the outlet of the spiral conveying pipe 311 for solid-liquid separation during kitchen waste compression.

[0028] In this embodiment, the crushing cylinder assembly and the spiral extrusion roller assembly, which are distributed vertically and connected at the inlet and outlet, can be used for crushing kitchen waste and extruding the crushed waste. This design utilizes two methods, crushing and extruding, to reduce the volume of waste. The two methods not only complement each other but also progressively improve the compression effect.

[0029] The crushing method not only significantly reduces the space occupied by the waste, but also produces more uniform waste particles, which is very beneficial for subsequent processing (such as incineration, composting, sorting, and anaerobic digestion). At the same time, when the crushed kitchen waste enters the spiral extrusion roller assembly, it facilitates the pressurization of the spiral extrusion roller assembly.

[0030] The method of compression, specifically, is as follows: Figure 4 , 5 6. The spiral extrusion roller assembly includes a spiral conveying pipe 311, the inner diameter of which decreases progressively along the direction of food waste conveying; a bolt conveying roller 312 disposed within the spiral conveying pipe 311; and several through holes 314 opened near the outlet of the spiral conveying pipe 311 for solid-liquid separation during food waste extrusion. This structural design, due to the progressively decreasing inner diameter of the spiral conveying pipe 311 along the direction of food waste conveying, reduces the internal voids of the waste when the bolt conveying roller 312 spirally conveys the waste fragments, making it more compact and dense. Meanwhile, at the outlet of the spiral conveying pipe 311... A through hole 314 is opened at the opening position, which can further achieve solid-liquid separation during the compression of garbage fragments. The above treatment method first reduces transportation costs, such as improving the utilization rate of load capacity (loose garbage filling the truck may not reach the load limit), thereby reducing the number of transportation trips and vehicle requirements, and saving a lot of fuel, labor and vehicle maintenance costs. Second, the garbage blocks after compression and solid-liquid separation are more regular and solid, making it easier to tie and fix with packing straps. Finally, the compaction process removes some of the air and liquid inside the garbage, which can make the garbage structure more compact, thereby reducing the emission of odors from decay to a certain extent.

[0031] This application utilizes a crushing cylinder assembly and a spiral extrusion roller assembly, which are distributed vertically and connected by inlet and outlet, to reduce the volume of waste through both crushing and extrusion. This not only facilitates subsequent packaging of the waste but also allows for the transport of the same weight of waste in fewer trips, significantly reducing transportation costs (fuel, labor, and vehicle wear and tear). Furthermore, the crushed and extruded waste has a higher density, enabling more efficient use of space when stored at transfer stations or treatment plants. Additionally, the extruded and extruded waste briquettes reduce the emission of odors from decay to some extent, thus improving the environment.

[0032] Furthermore, a first motor 313 is also provided at one end of the spiral conveying pipe 311 near the inlet, and the output end of the first motor 313 passes through the assembly hole opened at the end of the spiral conveying pipe 311 and is fixed to the bolt conveying roller 312, such as... Figure 2 , 3 As shown in Figures 4, 5, and 6, the rotation drive is used for the bolt conveying roller 312.

[0033] Furthermore, a recovery frame 315 is also provided below the spiral conveying pipe 311 to collect liquid dripping through the through hole 314, such as... Figure 1 , 2 As shown in Figure 3.

[0034] Example 2

[0035] In another embodiment of this utility model, the mounting support includes a bracket 111 and a support plate 112 fixed to the top of the bracket 111. The crushing cylinder assembly and the spiral extrusion roller assembly are respectively mounted on the upper and lower surfaces of the support plate 112. A connecting groove is opened in the middle of the support plate 112 and communicates with the outlet of the crushing cylinder assembly and the inlet of the spiral conveying pipe 311. A control valve 113 is provided in the connecting groove for opening and closing the connecting groove.

[0036] Control valve 113 is set as follows Figure 6 As shown, it is used as a control structure for switching on and off the crushing cylinder assembly and the spiral extrusion roller assembly.

[0037] Example 3

[0038] In another embodiment of this utility model, the crushing cylinder assembly includes a first cylinder 211 and a second cylinder 212 distributed vertically, wherein the second cylinder 212 is fixed on the upper surface of the support plate 112; a feeding bin 213 is provided on the side wall of the second cylinder 212 for feeding kitchen waste; and a cutting assembly and an extrusion plate assembly are provided inside the first cylinder 211 and the second cylinder 212 and distributed inward and outward, respectively for rotating cutting and extruding operations on the waste.

[0039] like Figure 1 , 4As shown in Figures 5 and 6, in this embodiment, the first cylinder 211 and the second cylinder 212 are arranged vertically and internally with cutting components and extrusion plate components arranged internally and externally. When kitchen waste is poured into the second cylinder 212 through the feeding bin 213, the cutting components and extrusion plate components can respectively realize the crushing and extrusion operations of the kitchen waste. The extrusion operation facilitates the pushing of the waste towards the cutting position and has the function of gathering the waste. In addition, when the control valve 113 is opened, the crushed waste is further accelerated to be discharged under the action of the extrusion operation.

[0040] Furthermore, the cutting assembly includes a central hole at the bottom of the first cylinder 211, and a vertical rod 214 is provided in the central hole. The bottom end of the vertical rod 214 extends into the interior of the second cylinder 212 and is provided with a cutting blade 216. The top end extends into the interior of the first cylinder 211 and is connected to the output end of the second motor 215 provided at the top of the first cylinder 211. Furthermore, a rotary sealing plug 217 is also provided between the vertical rod 214 and the central hole.

[0041] like Figure 4 , 5 As shown in Figure 6, one end of the vertical rod 214 is connected to the second motor 215, and the other end extends into the second cylinder 212 and is fixed with a cutting blade 216. When the second motor 215 is running, the garbage poured into the second cylinder 212 through the feed bin 213 can be cut and crushed by the high-speed rotating cutting blade 216.

[0042] Furthermore, the extrusion plate assembly includes a side hole annularly opened at the bottom of the first cylinder 211, each side hole being provided with a telescopic rod 218, wherein one end of the telescopic rod 218 extends into the interior of the second cylinder 212 and is fixed with a pressure frame 219, and the other end extends into the interior of the first cylinder 211 and is fixed with a connecting ring 220, and a spring 221 is provided on the outer wall of the telescopic rod 218 between the connecting ring 220 and the first cylinder 211; and a cam drive structure for the staggered extension and retraction of the pressure frames 219.

[0043] like Figure 4 , 5 As shown in Figure 6, one end of the telescopic rod 218 extends into the second cylinder 212 and is fixed with a pressure frame 219, while the other end extends into the first cylinder 211 and contacts the cam drive structure. When the cam drive structure drives several telescopic rods 218 to move downwards alternately, several pressure frames 219 can alternately press down on the garbage inside the second cylinder 212, realizing the garbage gathering process. Subsequently, each pressure frame 219 is reset by the spring 221, thereby realizing the repeated pressurization process of the squeezing plate assembly on the kitchen waste.

[0044] Furthermore, the cam drive structure includes a transmission ball 223 disposed at the top of each telescopic rod 218; and a slanted wheel 222 fixed to the upper part of the vertical rod 214, with the bottom surface of the slanted wheel 222 in contact with a plurality of transmission balls 223.

[0045] like Figure 6 As shown, the oblique cutting wheel 222 is fixed on the upper part of the vertical rod 214. When the second motor 215 drives the vertical rod 214 to rotate at high speed and causes the cutting blade 216 to perform cutting work, the oblique cutting wheel 222 rotates synchronously at high speed. At this time, when several transmission balls 223 contact the convex side of the oblique cutting wheel 222, they move downwards. When they contact the concave side of the oblique cutting wheel 222, the telescopic rod 218 is reset by the spring 221, thereby realizing the sequential pressing operation of several pressure frames 219.

[0046] Furthermore, several pressure frames 219 are placed above the cutting blade 216, such as... Figure 6 As shown, the cutting area of ​​the cutting blade 216 is separated from the pressing area of ​​the pressing frame 219, so that when the second motor 215, which is the same driving source, is running, the cutting and pressing of the waste inside the second cylinder 212 will not interfere with each other.

For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.
