[0031] EMBODIMENT

[0032] A garbage disposal system, as shown in Figure 1 , comprising a lifting device 1, a conveying device 2, a dry-wet separation device 3 and a compression device 4.

[0033] The lifting device 1 is used for lifting the garbage can and dumping the garbage in the garbage can onto the conveying device 2. As shown in Figures 2-3 the lifting device 1 comprises a lifting frame 11, a swing arm shaft 12, a swing arm 13, a bottom plate 14 and a lifting motor 15.

[0034] The swing arm shaft 12 is arranged in a horizontal manner and is rotatably connected to the lifting frame 11 through a bearing, the lifting motor 15 is fixed to the lifting frame 11 through bolts or screws, and the motor shaft of the lifting motor 15 is connected to one end of the swing arm shaft 12, for example, through a shaft coupling.

[0035] The swing arm 13 is in a long strip shape, arranged along the radial direction parallel to the swing arm shaft 12, and the root of the swing arm 13 is fixed to the swing arm shaft 12 through a key. The bottom plate 14 is fixed to the tip of the swing arm 13, and when the bottom plate 14 is in the lowest position, the bottom plate 14 is in a horizontal state, and at this time the swing arm 13 is in a vertical state. At the same time, a limiting block is also fixed on the lifting frame 11, so that the swing arm 13 in the vertical state can only rotate in one direction, and after rotating along this direction, the garbage can located on the bottom plate 14 is rotated around the axis of the swing arm shaft 12 to be lifted, and when the swing arm shaft 12 rotates more than 90°, the opening of the garbage can is turned to an inclined downward state, so that the garbage in it is dumped out.

[0036] At the same time, the swing arm 13 is also fixed with a blocking piece 16 for blocking the garbage can when dumping garbage, for example, the blocking piece 16 is in a frame shape, and the shape and size are matched with the opening of the garbage can, so that when the garbage can is turned to the state that the opening is inclined downward, the garbage can can be blocked by the blocking piece 16 to prevent the garbage can from falling off the lifting frame 11, and the frame-shaped blocking piece 16 will not affect the dumping of garbage from the garbage can.

[0037] The conveying device 2 is used for conveying the garbage dumped out of the garbage can to the dry-wet separation device 3, for example, the conveying device 2 is a belt conveyor. The dry-wet separation device 3 is used for dry-wet separation of the garbage conveyed from the conveying device 2.

[0038] As shown in Figures 4-5 the dry-wet separation device 3 comprises a cylinder 31, an axle 33, an inner shaft 38, a turnover conveying rod 39 and a separation motor 311.

[0039] The cylinder 31 is in a closed cylindrical tube structure, the cylinder 31 is horizontally arranged, and the bottom of the cylinder 31 is usually fixed with a separation support 32. One end of the cylinder 31 in the axial direction is provided with a feeding port 311, and this end is the leading end. The other end is called the tail end. The side wall of the cylinder 31 is provided with a feeding port 311 at the position of the largest horizontal diameter. The feeding port 311 is used to add the dry and wet garbage mixed material to be treated. On the side of the tail end, the side wall of the cylinder 31 is provided with a dry garbage outlet 312 at the position of the largest horizontal diameter. The dry garbage outlet 312 is usually arranged at a circumferential interval of 180° from the feeding port 311. The dry garbage outlet 312 is used for discharging dry garbage with relatively low density. On the side of the tail end, the side wall of the cylinder 31 is also provided with a wet garbage outlet 313 at the lowest position. The wet garbage outlet 313 is used for discharging wet garbage with relatively high density.

[0040] The wheel shaft 33 is a short shaft. The wheel shaft 33 is rotatably connected to the tail end face of the cylinder 31 through a bearing, and the wheel shaft 33 is coaxially arranged with the cylinder 31. The two ends of the wheel shaft 33 respectively extend into the inside of the cylinder 31 and protrude outside the cylinder 31. The part of the wheel shaft 33 extending into the cylinder 31 is fixedly installed with a wind wheel 34. The wind wheel 34 is an axial suction and radial exhaust centrifugal wheel. The dry garbage outlet 312 is opposite to the exhaust direction of the wind wheel 34.

[0041] A protective mesh cover 35 is also included. The protective mesh cover 35 is sleeved outside the wind wheel 34, and the protective mesh cover 35 is fixedly connected with the wheel shaft 33, so as to protect the wind wheel 34 through the protective mesh cover 35. In this embodiment, the protective mesh cover 35 is in a frustum structure, and the wind wheel 34 is located on the side of the large diameter end. Usually, the protective mesh cover 35 includes two (or more) mesh pieces uniformly divided in the circumferential direction. The two mesh pieces are fixedly connected with each other through screws or bolts. Usually, the end portions of the two mesh pieces are respectively fixed with semicylindrical clamping sleeves. After the two clamping sleeves are fixed through screws or bolts, the outer wall of the wheel shaft 33 can be clamped, so as to realize the fixation of the protective mesh cover 35. A key can be arranged between the clamping sleeve and the wheel shaft 33, so as to prevent the protective mesh cover 35 from rotating relative to the wheel shaft 33.

[0042] It is easy to understand that although the protective mesh cover 35 does not affect the air suction of the wind wheel 34, and the conical structure can effectively prevent garbage from accumulating on the surface. However, this is not absolute. Therefore, this embodiment is also provided with a cleaning member 36 for cleaning the surface of the protective mesh cover 35, such as a brush. The brush is fixedly connected with the inner wall of the cylinder 31. When the protective mesh cover 35 rotates with the wheel shaft 33, the brush can clean the surface of the protective mesh cover 35. For example, the brush is in a strip shape and is arranged obliquely, so as to effectively clean the conical surface of the protective mesh cover 35. Usually, the cleaning member 36 is arranged at the highest position in the cylinder 31, so as to reduce the interference of the garbage in the cylinder 31 on the cleaning work.

[0043] It is easy to understand that the cleaning piece 36 is a consumable part or a wearing part, which needs to be replaced regularly, therefore, the present embodiment sets an outwardly opening hatch 37 at the highest point of the tail end side wall of the cylinder 31, the hatch 37 is designed with a hinge for easy opening and closing, and the hatch 37 is fixed by screws or rotatable handles, and the cleaning piece 36 is detachably fixed to the inner wall of the hatch 37 by bolts or screws. In this way, the cleaning piece 36 can be turned out of the cylinder 31 by opening the hatch 37, thereby facilitating the replacement of the cleaning piece 36.

[0044] The wheel shaft 33 is hollow, and the inner shaft 38 is coaxially inserted into the wheel shaft 33. The front end of the inner shaft 38 is rotatably connected to the front end face of the cylinder 31 by a bearing, and the tail end of the inner shaft 38 is rotatably connected to the wheel shaft 33 by a bearing, and the tail end of the inner shaft 38 is exposed from the wheel shaft 33 for easy connection of the inner shaft 38 to the separation motor 310.

[0045] The turnover conveying rod 39 is in a spiral shape, and is arranged outside the inner shaft 38 with the axis of the cylinder 31 as the center, and is fixedly connected to the inner shaft 38 by a connecting rod. The diameter of the turnover conveying rod 39 is smaller than the inner diameter of the cylinder 31, and if necessary, a flexible material made scraping strip (not shown in the figure) can be applied on the turnover conveying rod 39, so that the inner wall of the cylinder 31 can be cleaned while the turnover conveying rod 39 rotates, avoiding garbage accumulation. In order to improve the turnover conveying effect, the turnover conveying rod 39 can be configured to be more than two and arranged uniformly in the circumferential direction.

[0046] The separation motor 310 is located at the tail end of the cylinder 31. Generally, the separation motor 310 is not directly fixed on the outer wall of the cylinder 31, but is fixed on the separation support 32. The tail end of the wheel shaft 33 and the tail end of the inner shaft 38 are respectively mechanically connected with the motor shaft of the separation motor 310, and generally the rotating speed of the inner shaft 38 is lower than that of the wheel shaft 33. For example, two driving pulleys are installed on the motor shaft of the separation motor 310, and corresponding driven pulleys are installed on the inner shaft 38 and the wheel shaft 33 respectively. The separation motor 310 drives the wheel shaft 33 and the inner shaft 38 to rotate through the pulley transmission mechanism. Only the diameter of the pulley needs to be changed to make the wheel shaft 33 rotate at high speed and the inner shaft 38 rotate at low speed. Of course, in other embodiments, the separation motor 310 can also drive the inner shaft 38 to rotate through a gear transmission mechanism or a speed reducer. Of course, in other embodiments, two separation motors 310 can be arranged, and the two separation motors 310 are respectively used to drive the wheel shaft 33 and the inner shaft 38 to rotate, and the separation motor 310 can be configured as a variable frequency speed regulation motor, so that the rotating speed of the wheel shaft 33 and the inner shaft 38 can be flexibly adjusted. It is easy to understand that the turnover conveying rod 39 can also rotate at a relatively high speed. At this time, the turnover conveying rod 39 can also play a certain crushing effect on the wet garbage. The specific rotating speed and diameter can be set according to the actual use scene.

[0047] The compression device 4 is used for compressing the dry garbage separated by the dry-wet separation device 3.

[0048] As shown in Figures 6-8 The compression device 4 includes a compression cylinder 41. The compression cylinder 41 is installed vertically, for example, the cross section is rectangular, and of course it can also be circular. One of the side walls of the compression cylinder 41 is provided with a filling port 42 for filling garbage inward. In this embodiment, the filling port 42 is connected with the dry garbage outlet 312 on the cylinder 31 through a pipeline.

[0049] The inside of the compression cylinder 41 is provided with a compression plate 43 which is movable along the height direction thereof, that is, the axial direction of the compression cylinder 41. The shape of the compression plate 43 is the same as the cross section of the inner wall of the compression cylinder 41, but the size of the compression plate 43 is smaller than the cross section size of the inner wall of the compression cylinder 41.

[0050] The compression cylinder 41 is also fixedly provided with a pressing device 44 for driving the compression plate 43 to ascend and descend. The pressing device 44 is configured as a hydraulic cylinder, and is fixed on the top outer wall of the compression cylinder 41. The top of the compression cylinder 41 is also provided with a through hole for the output shaft of the hydraulic cylinder to pass through. The output shaft of the hydraulic cylinder is fixedly connected with the top surface of the compression plate 43.

[0051] The lower side wall of the compression cylinder 41 is also provided with a discharge port, which is located at two opposite sides of the compression cylinder 41, for example, circumferentially spaced 180°, and is at a lower position. The discharge port is detachably connected with a hatch 45, for example, one end of the hatch 45 is pivotally connected with the side wall of the compression cylinder 41 through a hinge, and the other end of the hatch 45 is detachably fixedly connected with the side wall of the compression cylinder 41 through a lock, a latch or a screw, etc., and can close the discharge port when the hatch 45 is closed.

[0052] In use, the hatch 45 is closed, the pressure plate 43 is first lifted under the driving of the pressing device 44, then the garbage is loaded into the compression cylinder 41 through the loading port 42, and then the pressure plate 43 is pressed to compress the originally loose garbage into a relatively dense block, the pressure plate 43 is lifted to reset, and the relatively dense block of garbage can be obtained by opening the hatch 45, thereby reducing the overall volume of the garbage and being suitable for transportation.

[0053] In this embodiment, the inside of the compression cylinder 41 is also provided with a bottom plate 46 which is movable along the height direction thereof, the shape of the bottom plate 46 is also the same as the cross section of the inner wall of the compression cylinder 41, and the size of the bottom plate 46 is also smaller than the cross section size of the inner wall of the compression cylinder 41, and the bottom plate 46 is usually configured to have the same shape and size as the pressure plate 43. The bottom plate 46 is located below the pressure plate 43, and is usually at the bottom position of the compression cylinder 41, for carrying the garbage when the pressure plate 43 is pressed.

[0054] The bottom plate 46 is connected with a cable 47 between the pressure plate 43, and the length of the cable 47 is smaller than the maximum distance between the pressure plate 43 and the bottom plate 46, so that the bottom plate 46 can be lifted by the cable 47 before the pressure plate 43 is lifted to the highest point under the driving of the pressing device 44. However, the cable 47 is also configured to have a certain length, so that a sufficient distance can be left between the pressure plate 43 and the bottom plate 46, so that a sufficient amount of garbage to be compressed can be loaded into the compression cylinder 41.

[0055] There are usually more than two cables 47, and the cables 47 are circumferentially uniformly arranged around the central axis of the compression cylinder 41. In addition, the cables 47 are also arranged at the side positions of the bottom plate 46 and the pressure plate 43, so as to avoid the situation that the cable 47 is also pressed into the garbage when the pressure plate 43 is pressed.

[0056] Of course, in other preferred embodiments, the pull cable 47 can also be replaced by a rigid pull rod, for example, the pull rod is fixedly connected at the four corners of the base plate 46, the upper end of the pull rod is then inserted through the perforations at the four corners of the pressing plate 43, and then a limiting block is fixedly connected (for example, threaded) at the upper end of the pull rod. In this way, when the pressing plate 43 is pressed down, the pressing plate 43 will only move relative to the pull rod, and the pull rod will not be pressed into the garbage. When the pressing plate 43 rises to the position of touching the limiting block, the pressing plate 43 can drive the base plate 46 to rise together through the pull rod.

[0057] In this way, the setting of the base plate 46 makes the compressed block-shaped garbage not stuck at the bottom of the compression cylinder 41, so that it is loosened under the driving of the base plate 46, and then it is convenient to take it out of the hatch 6.

[0058] In the embodiment, the inner wall of the compression cylinder 41 is also provided with two or more than two slide rails (or slide grooves) in the circumferential direction, and the corresponding positions of the pressing plate 43 and the base plate 46 are provided with slide blocks matched with the slide rails.

[0059] The use process of the garbage disposal system provided by the embodiment of the utility model is as follows:

[0060] In use, the garbage can containing garbage is placed on the bottom plate 14 of the lifting device 1, then the lifting motor 15 drives the swing arm shaft 13 to rotate, so that the garbage can is turned over to the state that the opening of the garbage can is inclined downward, and the garbage is poured on the conveying device 2. The conveying device 2 conveys the garbage poured thereon to the cylinder body 31 of the dry-wet separation device 3. The separation motor 310 is started, the separation motor 310 drives the wind wheel 34 and the turnover conveying rod 39 to rotate, the turnover conveying rod 39 is used for conveying the garbage to the tail end side of the cylinder body 31, and at the same time, the turnover conveying rod 39 is also used for stirring the garbage, so that the buried dry garbage is turned out, the wind wheel 34 generates wind power through rotation, so that the dry garbage with relatively light density is blown out of the dry garbage outlet 312, and the wet garbage with relatively heavy density is discharged from the wet garbage outlet 313. In the process of rotation of the wheel shaft 33, the cleaning piece 36 can clean the garbage adhered to the surface of the protective mesh cover 35, so as to ensure the smoothness of air intake and blowing. Then the dry garbage is blown into the compression device 4, in the state that the hatch 45 is closed, the pressing plate 43 is lowered under the driving of the pressing device 44, so as to compress the originally loose dry garbage into relatively dense blocks, then the pressing plate 43 is reset and raised under the driving of the pressing device 44, and the relatively dense block-shaped garbage can be obtained by opening the hatch 45, so as to reduce the overall volume of the garbage, which is suitable for transportation.

[0061] The embodiments of the present application are described in detail in combination with the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
