[0002] In order to make the garbage leachate in the garbage bin flow out smoothly, a grid is arranged at the lower part of the garbage bin, the garbage leachate is discharged through the grid, collected in the leachate collection channel and then transported to the leachate treatment system by the leachate pump for treatment. However, in the actual operation process, in order to ensure the discharge and collection of the garbage leachate, a diversion slope is arranged at the bottom of the garbage bin, and part of the garbage will move towards the grid along with the flow of the leachate, which not only escapes from the grid and accumulates in the leachate collection channel, but also accumulates on the inner side of the grid, causing blockage. With too much garbage accumulation, the diversion of the leachate and the subsequent treatment effect are seriously affected. Although there are many existing devices to reduce the degree of garbage blockage on the inner side of the grid, the cleaning work in the leachate collection channel still needs to be done frequently by workers, who use hand-held nets to fish and collect the garbage in the leachate collection channel, and then bag the collected garbage and take it out of the leachate collection channel, and then put it back into the garbage bin.

The screw conveying mechanism carries the garbage block away from the grid, avoiding secondary garbage blocking of the grid, completely solving the labor cost and safety risk brought by manual entry into the leachate collecting channel to bag and transport the scattered garbage, and ensuring the personal safety of the staff.

DETAILED DESCRIPTION

[0033] The application provides a garbage bin leachate guide and discharge anti-blocking system. In order to make the purpose, technical scheme and effects of the application more clear and explicit, the application is further described in detail below with reference to the drawings and examples.

In addition, "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0035] Please refer to Figures 1 to 6 As shown in the drawings, the present application provides a garbage bin leachate drainage anti-blocking system, which comprises a horizontal movement driving mechanism 3 arranged above the leachate collection channel 81, a blockage clearing mechanism 4 arranged on the horizontal movement driving mechanism 3 and used for clearing the blockage of the grid 11, a garbage compression return bin mechanism 5 arranged in the leachate collection channel 81 and below the grid 11, and a screw conveying mechanism 6 arranged in the garbage bin 1 and close to the grid 11, the screw conveying mechanism 6 crosses the grid 11 and conveys the garbage at the grid away from the grid 11; the garbage compression return bin mechanism 5 comprises a collection box 51 with an upper opening and swingingly arranged on the wall of the leachate collection channel, a lateral extrusion assembly 52 arranged on one side of the collection box 51, a push-return bin assembly 54 arranged at the bottom of the collection box 51, and a horizontal driving assembly 7 for driving the collection box 51 to swing from an inclined state to a horizontal state, the side and bottom surfaces of the collection box 51 are uniformly provided with filter holes 511 for discharging leachate, the lateral extrusion assembly 52 is used for extruding the garbage in the collection box 51 to the other side of the collection box 51 to realize compression, and the push-return bin assembly 54 is used for pushing the compressed garbage into the garbage bin 1, and the screw conveying mechanism 6 transports the compressed garbage away from the grid 11.

[0036] In fact, the garbage bin 1 is provided with a diversion slope 9 at the bottom, and the slope of the diversion slope 9 is not less than 2% to meet the requirements of the Design Specification for Domestic Waste Incineration Plants GB50850-2013, so that not only the leachate flows towards the grid 11, but also part of the garbage moves towards the grid 11 along with the flow of the leachate. When the grid 11 is blocked due to the accumulation of garbage, the horizontal movement driving mechanism 3 is started, which drives the blockage clearing mechanism 4 arranged above the leachate collection channel 81 to move along the length direction of the grid 11; during the movement of the blockage clearing mechanism 4, each adjacent rail gap (i.e. liquid outlet gap) of the grid 11 is aligned one by one, and through the pre-set blockage clearing action (such as scraping, dredging, etc.), the garbage and sundries accumulated on the inner side of the grid 11 are stripped off, ensuring the smoothness of the grid liquid outlet gap and ensuring the normal downward infiltration of the leachate.

[0037] The collecting box 51 is in an inclined state when collecting garbage, and the opening thereof extends along the length direction of the grid 11. The collecting box 51 collects, on one hand, the garbage falling into the channel along with the leachate escaping from the grid 11 in daily operation, and on the other hand, the garbage stripped off and taken away from the grid 11 by the blockage cleaning mechanism 4 in the process of blockage cleaning, so as to avoid the accumulation and blockage of the two types of garbage in the leachate collecting channel 81. Meanwhile, the filter holes 511 on the side surface and the bottom surface of the collecting box 51 can separate and discharge the leachate wrapped in the garbage, so that the leachate continues to flow to the collecting tank, and does not affect the flow guiding process.

[0038] When the garbage in the collecting box 51 accumulates to a preset amount, the lateral extrusion assembly 52 on one side of the collecting box 51 is started. The lateral extrusion assembly 52 applies extrusion force to the other side surface of the collecting box 51 to extrude the loose garbage in the box into a block shape. This process, on one hand, reduces the volume of the garbage, so that the garbage forms a stable block for subsequent pushing; on the other hand, the leachate remaining in the garbage is extruded out, and the leachate is discharged through the filter holes 511, so as to further reduce the water content of the garbage and avoid the influence of too much water on the garbage incineration heat value after returning to the bin.

[0039] In fact, in addition to the way of returning through the grid, the garbage block can also return to the inside of the garbage bin 1 through a return port opened in the wall of the leachate collecting channel and penetrating the inside of the garbage bin 1. The return port is located beside the grid. In the mode of setting the return port, the push-return assembly faces the return port, and a pneumatic door for controlling the opening and closing of the return port is arranged on the inner wall of the garbage bin. Under normal circumstances, the pneumatic door is closed to prevent garbage from escaping through the return port. The pneumatic door will only be opened when the garbage block returns. The pneumatic door can specifically drive the door body to move vertically by a pneumatic cylinder, so as to close or open the return port. Compared with the way of returning through the grid, the way of returning through the return port will increase the construction difficulty and cost.

[0040] The following describes the way of returning through the grid. After extrusion, the back flat driving assembly 7 drives the originally inclined collecting box 51 to swing around the connecting point with the wall of the leachate collecting channel 81 until the collecting box 51 is in a horizontal state. At this time, the opening direction of the collecting box 51 is aligned with the liquid outlet of the grid 11. The push-return assembly 54 pushes the compressed garbage block out of the collecting box 51, so that it returns to the inside of the garbage bin 1 through one of the liquid outlet gaps (the gap is smooth after blockage cleaning) of the grid 11 and pushes towards the spiral conveying mechanism 6.

[0041] At the same time, after the spiral conveying mechanism 6 is started, due to the structural design of the spiral conveying mechanism 6 across the grid 11, the garbage blocks returned to the bin are stably conveyed away from the grid 11 by the spiral blades of the spiral conveying mechanism 6, so that the garbage blocks are separated from the grid 11 area, avoiding the garbage blocks from being accumulated again near the grid 11 and blocking the grid liquid outlet gap again, and finally completing the whole anti-blocking and garbage recycling process.

[0042] The garbage bin leachate guide and prevention system provided by the application realizes the automatic operation of garbage unblocking, collecting, compressing, returning to the bin and conveying through the cooperation of each mechanism, especially the innovative design of the garbage compression and return mechanism 5. The collecting box 51 not only intercepts the garbage that escapes from the grid 11 and falls into the leachate collecting channel 81 during daily operation, avoiding the long-term accumulation of such garbage in the leachate collecting channel 81 to form a blockage, but also receives the garbage stripped off during the cleaning of the grid by the unblocking mechanism 4, preventing the garbage produced by the unblocking from being retained in the leachate collecting channel 81. The leachate flows smoothly to the leachate collecting tank 82 through the filter hole 511, and the garbage is left in the box waiting for processing. The comprehensive collection of the two types of garbage makes it unnecessary to manually enter the leachate collecting channel 81 to salvage and separate the garbage. Then, the loose garbage is compressed into smaller and more stable clumps by the lateral extrusion assembly 52, and the residual leachate in the garbage is squeezed out through the filter hole 511. The volume of the compressed garbage is greatly reduced, and the push-return assembly 54 automatically generates a pushing force to push the compressed garbage out of the collecting box 51, so that it can reliably pass through the grid liquid outlet gap that has been cleaned and be pushed to the spiral conveying mechanism 6 to realize the return to the bin. The spiral conveying mechanism 6 transports the garbage away from the grid, avoiding the secondary blocking of the grid 11, and completely solving the problems of labor cost and safety risk caused by manual entry into the leachate collecting channel 81 to bag and transport the scattered garbage, thereby ensuring the personal safety of the staff.

[0043] The garbage bin leachate guide and prevention system provided by the application can operate continuously all day long. The horizontal moving drive mechanism 3 and the unblocking mechanism 4 are started as needed according to the monitored grid blocking situation, the collecting box 51 receives garbage in real time, and the lateral extrusion assembly 52, the push-return assembly 54 and the spiral conveying mechanism 6 are started as needed. When the horizontal moving drive mechanism 3 and the unblocking mechanism 4 are not in working state, the horizontal moving drive mechanism 3 and the unblocking mechanism 4 will move to the non-working area and will not interfere with the normal work of the push-return assembly. The horizontal moving drive mechanism 3 and the unblocking mechanism 4 are started as needed according to the monitored grid blocking situation. Specifically, the staff in the monitoring room understands the real-time situation of the grid through the pictures taken by the monitoring camera and manually controls the horizontal moving drive mechanism 3 and the unblocking mechanism 4 to work.

[0044] The horizontal moving driving mechanism 3, the blockage cleaning mechanism 4 and the push-return bin assembly 54 are actually arranged on the same control system (PLC control system), and the working logic sequence of each mechanism can be realized by programming by those skilled in the art, that is, once the horizontal moving driving mechanism 3 and the blockage cleaning mechanism 4 start to work and are in the working period, the push-return bin assembly 54 in the inclined state will not swing to the horizontal posture to perform the return bin action, and after the horizontal moving driving mechanism 3 and the blockage cleaning mechanism 4 complete the work, the push-return bin assembly 54 is started again as required. When the push-return bin assembly 54 is in the garbage compression and push-return bin working period, the horizontal moving driving mechanism 3 and the blockage cleaning mechanism 4 will wait for the push-return bin assembly 54 to complete the work and then start, so that the movement time sequence of the two is completely staggered, and interference between the push-return bin assembly 54 and the blockage cleaning mechanism 4 is completely avoided.

[0045] Compared with the mode of artificial periodic entry into the channel for cleaning, the garbage in the channel can be processed more timely, and the problems of channel blockage and poor percolate drainage caused by untimely artificial cleaning can be avoided. At the same time, the automatic processing efficiency is much higher than that of manual fishing (without time-consuming steps such as manual back and forth and bagging), and the overall operation efficiency of the percolate drainage system is greatly improved.

[0046] It should be noted that the layout of each mechanism is designed around the existing garbage bin grid and percolate collection channel 81, the horizontal moving driving mechanism 3 is erected above the percolate collection channel 81, the collection box 51 is placed in the percolate collection channel 81, and the screw conveying mechanism 6 is arranged close to the grid 11, without the need for large-scale modification of the garbage bin main body structure; at the same time, the cooperative operation of each mechanism adapts to the existing garbage incineration process, can quickly integrate into the existing garbage treatment system, and reduces the modification and application cost.

[0047] In order to detect the amount of garbage in the collection box 51, a sensor (such as a liquid level sensor, a weight sensor, etc.) can be provided on the collection box 51. When the sensor detects that the height of the garbage accumulation reaches a set threshold, a signal will be sent to the control system, thereby triggering the lateral extrusion assembly 52 to start compressing the garbage. Specifically, the weight sensor is installed at the bottom of the collection box 51, and the liquid level sensor is installed on the inner wall of the collection box. Both sensors work together to detect the threshold value of any one sensor, for example, the weight sensor is set to a threshold value (such as 5kg, corresponding to a loose garbage volume of about 0.01m³), and the liquid level sensor is set to a threshold value (such as 70% of the height of the collection box, corresponding to a loose garbage volume of about 0.008m³). When the threshold value is reached, the garbage compression and return mechanism will be triggered to act. In fact, the threshold value of the sensor is designed to be reasonably set, for example, the maximum compressible return volume of garbage is 100%, so the threshold value will be set to 60%-70% to cope with the situation that the garbage suddenly increases (such as more than 10%) beyond the threshold value. Even if the threshold value is exceeded, the garbage can still be compressed and returned; correspondingly, the depth of the collection box 51 is also designed redundantly, so that even if the garbage increases, the block-shaped garbage will only lengthen in length, and the width will still be less than the liquid outlet width of the grid 11, ensuring that the block-shaped garbage is smoothly returned.

[0048] It should be noted that under normal circumstances, the garbage escapes are relatively scattered, and the situation of garbage escaping in large quantities occurs very rarely. If the amount of garbage escaping instantaneously is too large for the garbage compression and return mechanism to handle, the staff will enter the channel to clean up to ensure smooth subsequent production.

[0049] Specifically, please refer to Figures 4 to 6 The lateral extrusion assembly 52 includes a first cylinder 522 fixed to one side of the collection box 51, and a first extrusion plate 521 disposed in the collection box 51 and connected to the output end of the first cylinder 522, the first extrusion plate 521 facing the other side of the collection box 51.

[0050] When the amount of garbage in the collection box 51 reaches a preset threshold, the first cylinder 522 drives the first extrusion plate 521 to move towards the other side of the collection box 51 (i.e. horizontally). As the first extrusion plate 521 continues to move, it pushes the loose garbage in the collection box 51 to one side of the collection box 51, and the extrusion force of the first extrusion plate 521 cooperates with the side of the collection box 51 to force the garbage to compress into a block structure with high density, providing a basis for the subsequent pushing of the return assembly 54, preventing loose garbage from being stuck in the outlet of the collection box 51 or the gap between the grids; at the same time, the extrusion force will force the leachate wrapped in the garbage to penetrate through the pre-set filter holes 511 on the side and bottom of the collection box 51, and then flow into the leachate collection channel 81 and the leachate collection pool 82.

[0051] Further, please refer to Figures 4 to 6, the outer end surface of the collecting box 51 is provided with a second cylinder 533, the output end of the second cylinder 533 is connected with a second extrusion plate 532, the second extrusion plate 532 is towards the inner end surface of the collecting box 51 and is used for extruding the garbage compressed by the first extrusion plate 521. When the piston rod of the first cylinder 522 reaches the maximum stroke, the first extrusion plate 521 stops moving, keeps the initial extrusion state of the garbage, and waits for the second stage of compression. At this time, the piston rod of the second cylinder 533 drives the second extrusion plate 532 connected therewith to move, the extrusion direction (longitudinal direction) of the second extrusion plate 532 is perpendicular to the extrusion direction of the first extrusion plate 521, the second extrusion is applied to the garbage block which has been preliminarily sized, and the garbage volume is further compressed, the residual leachate is squeezed out, the garbage density is further improved, and finally the garbage is shaped into a regular square block. When the bidirectional extrusion is completed, the second extrusion plate 532 and the first extrusion plate 521 still extrude the garbage to keep the garbage stable, then the control system controls the start of the back driving assembly 7, drives the collecting box 51 to swing to the horizontal posture, then controls the second cylinder 533 to drive the second extrusion plate 532 to reset, and then controls the first cylinder 522 to drive the first extrusion plate 521 to reset. At this time, the square-shaped garbage is stably stayed in the collecting box 51, waiting for the push and shoot back assembly 54 to push. Since the garbage has been shaped into a regular square block, it will not be stuck in the outlet of the collecting box 51 or the gap between the grid liquid outlets during the pushing process due to irregular shapes (such as protrusions and depressions of loose garbage), and can smoothly pass through the grid 11 along the preset path and accurately fall into the spiral conveying mechanism 6.

[0052] In the embodiment, please refer to Figures 4 to 6 , the push and shoot back assembly 54 includes a third cylinder 541 fixed on the bottom surface of the collecting box 51, and a push and shoot plate 542 arranged in the collecting box 51 and connected with the output end of the third cylinder 541, the push and shoot plate 542 is towards the upper opening of the collecting box 51 and is used for pushing the compressed garbage out of the collecting box 51. When the garbage in the collecting box 51 is bidirectionally and crossly extruded to form a high-density square-shaped garbage, the back driving assembly is first started to drive the originally inclined collecting box 51 to swing around the connecting point with the wall of the leachate collecting channel until the collecting box 51 is in a horizontal state. At this time, the upper opening of the collecting box 51 is accurately aligned with one of the liquid outlets of the upper grid, the piston rod end of the third cylinder 541 drives the fixedly connected push and shoot plate 542 to move synchronously and quickly, stably pushes the compressed garbage block in the direction of the upper opening of the collecting box 51, the push and shoot plate continuously applies stable and strong pushing force, and the compressed garbage block is guided along the inner wall of the collecting box until it completely passes through the upper opening of the collecting box 51 and smoothly passes through the aligned grid liquid outlet, enters the upper garbage bin 1, and completes the garbage pushing and shooting action. After the pushing and shooting is completed, the piston rod of the third cylinder 541 is reset to drive the push and shoot plate 542 to return to the initial position, and waits for the next round of pushing and shooting process.

[0053] In the present embodiment, the two outer sides of the collection box 51 are each provided with an ear chamber 516, the ear chamber 516 is provided with a bearing seat, two pivot seats 514 are provided on the wall in the leachate collection channel 81, the inner side of the two pivot seats 514 is provided with a pivot 515 extending into the ear chamber 516, and the pivot 515 is rotatably connected with the bearing on the bearing seat; the back-to-flat driving assembly 7 comprises a fourth cylinder 71, the cylinder body of the fourth cylinder 71 is connected with the wall in the leachate collection channel 81 through a first hinged seat 72, and the end of the piston rod of the fourth cylinder 71 is connected with the inner end face of the collection box 51 through a second hinged seat 73.

[0054] In order to ensure that the garbage escaping from the grid 11 can smoothly enter the collection box 51 when the collection box 51 is in a horizontal state, an inclined state or a switching process between the two states, a transition plate 12 flush with the installation bottom surface of the grid 11 is arranged on the wall in the leachate collection channel 81, and the length of the transition plate 12 is slightly less than the length of the upper opening of the collection box.

[0055] In the daily garbage collection stage, as shown in Figure 2 , the collection box 51 is in an inclined state, the height of the upper opening of the collection box 51 is lower than the height of the transition plate 12, the outer transverse edge of the transition plate 12 is directly below the upper opening of the collection box 51, and the garbage (daily garbage or unblocking garbage) escaping from the grid 11 is smoothly slid to the collection box 51 after being supported and transitioned by the transition plate 12: at this time, the piston rod of the fourth cylinder 71 is in a retracted state, and the inclination angle is designed to prevent interference between the push-and-return bin assembly 54 and the unblocking mechanism 4, and to ensure that the garbage (daily garbage or unblocking garbage) escaping from the grid 11 can naturally slide to the bottom of the collection box 51 under the action of gravity, and at the same time, the filter holes 511 on the side and bottom surfaces of the collection box 51 can smoothly drain leachate, avoiding garbage accumulation in the box to block the filter holes 511. Among them, the bearing seat in the ear chamber 516 on the two outer sides of the collection box 51 and the pivot 515 on the inner side of the pivot seat 514 are rotatably connected through the bearing, forming a stable rotation fulcrum, providing a basis for subsequent posture switching.

[0056] When the garbage in the collection box 51 is completed bidirectional extrusion compression, and it is necessary to switch to a horizontal posture to cooperate with the work of the push-and-return bin assembly 54, the back-to-flat driving assembly 7 is started: the piston rod of the fourth cylinder 71 starts to extend from the retracted state, and the piston rod will exert an upward pushing force on the inner end face of the collection box when it is stretched. Under the action of the pushing force, the collection box 51 slowly swings around the pivot as the axis, and gradually lifts back to flat, during the lifting back-to-flat process, the outer transverse edge of the transition plate 12 is always directed towards the upper opening of the collection box 51, and the transition plate 12 and the collection box 51 do not interfere with each other, ensuring that the garbage escaping from the grid 11 can smoothly fall into the collection box 51 during the posture switching process of the collection box 51. See Figure 3As shown, the fourth cylinder 71 stops extending and keeps the current length of the piston rod, so that the collecting tank 51 is stably maintained in a horizontal posture, and the inner end surface of the collecting tank 51 is flush with the outer transverse edge of the transition plate 12 to achieve connection. At this time, the push-return bin assembly 54 can start the push action to smoothly push the compressed garbage block out of the collecting tank and through the grid 11. When the garbage push-return bin is completed, the piston rod of the fourth cylinder 71 starts to contract to exert a downward pulling force on the inner end surface of the collecting tank 51. The collecting tank 51 again swings in reverse around the pivot as the axis to gradually recover to the initial inclined posture, waiting for the next round of garbage collection and compression process.

[0057] It can be understood that if the garbage block is pushed out when the collecting tank 51 is in an inclined state, the garbage block is thrown to the grid 11, and due to the possibility of blockage of the grid 11 and the collision with the grid rail during the throwing process due to the deviation of the direction, the compressed garbage block is broken, and the debris falls into the leachate collecting channel 81, causing secondary blockage. Therefore, after adjusting the collecting tank 51 to a horizontal state, the inner end surface of the collecting tank 51, the transition plate 12 and the installation bottom surface of the grid 11 are flush, the push plate 542 uniformly pushes the garbage block in the horizontal direction, and the forces on each part of the garbage block are uniform. Even if there is garbage blockage on the inner side of the grid 11, the garbage block can be pushed into the garbage bin 1 by the pushing force, ensuring that the garbage block is smoothly returned to the bin.

[0058] It should be noted that generally, the escaped garbage is collected by the collecting tank 51, but if a small amount of garbage falls into the channel, it is actually manually cleaned according to the actual situation. It can be understood that the garbage bin leachate drainage anti-blocking system is an auxiliary system for solving the problem of frequent manual cleaning of the channel, greatly reducing the number of manual cleaning, improving the garbage condition of the channel, and the worker can enter the treatment according to the complexity of the channel.

[0059] In one embodiment, the push plate 542 can pass through the grid 11 under the drive of the third cylinder 541, so that the push plate 542 can pass through the grid liquid outlet together with the garbage block, continuously exerting a pushing force on the garbage block until the garbage block is completely pushed into the garbage bin 1 (the front end of the push plate can extend into the garbage bin by 5-10 cm), completely avoiding the garbage block remaining in the grid liquid outlet.

[0060] In addition, the push plate 542 is provided with brush hairs on both sides for cleaning the grid rail. When the push plate 542 passes through the grid 11 under the drive of the third cylinder 541, the brush hairs on both sides can be in close contact with the surface of the grid rail, and the rail is wiped during movement. The surface of the cleaned grid rail has no impurities, which can avoid the garbage block being stuck or damaged due to the attachment of impurities on the rail when the garbage block is pushed through the grid 11 by the push plate; at the same time, the cleaned grid gap is unobstructed, which provides protection for subsequent leachate infiltration.

[0061] SeeFigure 4 As shown, the outer end surface of the collection tank 51 is a filter screen 512 structure, the filter screen 512 adopts a large mesh, and after the leachate enters the collection tank 51, it can not only be discharged through the side and bottom filter holes 511, but also quickly flow to the leachate collection channel 81 through the outer end surface filter screen 512; compared with relying only on the filter holes 511 at the side and bottom, the liquid discharge area is increased, avoiding the delay of the guide and discharge caused by the retention of the leachate in the collection tank 51. In addition, when the garbage in the collection tank 51 is compressed, a large amount of residual leachate inside the garbage will be squeezed out; the outer end surface filter screen 512 can serve as the main discharge outlet of the extrusion process, and the high-pressure leachate generated by extrusion can quickly break through the gap between the garbage and be directly discharged outside the tank through the large-mesh filter screen 512, avoiding the difficulty of separating the leachate from the compressed garbage, further reducing the water content of the garbage, and accelerating the guide and discharge of the leachate.

[0062] Because the filter screen 512 cannot bear the weight of the second air cylinder, the second air cylinder is fixed on the collection tank 51 through the mounting frame 531.

[0063] Specifically, please refer to Figure 7 , the screw conveying mechanism 6 includes a fixed frame 61, a rotating shaft 62, a conveying drive motor 63 and a speed reducer 64, the fixed frame 61 is fixed on the wall surface of the garbage bin 1, the fixed frame 61 is provided with a first receiving seat 65 rotatably connected with one end of the rotating shaft 62, the ground of the garbage bin 1 is provided with a second receiving seat 66 rotatably connected with the other end of the rotating shaft 62, and the outer wall of the rotating shaft 62 is provided with a spiral blade 68; the spiral blade 68 on the outer wall of the rotating shaft 62 forms a continuous conveying channel when rotating; after the garbage block is sent into the garbage bin 1 by the push-back bin assembly 54, the slowly rotating spiral blade 68 moves the garbage block away from the grate 11, avoiding the garbage block staying near the grate and mixing with other garbage in the bin for fermentation.

[0064] Because there may be garbage accumulation inside the grate 11 to bury the screw conveying mechanism 6, in order to prevent the garbage from affecting the heat dissipation of the conveying drive motor 63, and the mist of the garbage and leachate from eroding the conveying drive motor 63, the conveying drive motor 63 is installed on the wall inside the leachate collection channel 81, the speed reducer 64 is installed on the fixed frame 61, and the input end of the speed reducer 64 is in transmission connection with the output end of the conveying drive motor 63 through a transmission shaft 67, and the transmission shaft 67 extends through the wall inside the leachate collection channel 81 to the inside of the garbage bin 1. In fact, in order to avoid the garbage affecting the rotation of the transmission shaft 67, a protective sleeve can be provided outside the transmission shaft 67.

[0065] See Figures 8 to 13As shown, the transverse driving mechanism 3 includes two parallel rails 31 above the leachate collection channel 81 through a support and a moving trolley 32 running on the rails 31. The clogging cleaning mechanism 4 includes a rotating unclogging assembly 41, a hydraulic power assembly 42 for driving the rotating unclogging assembly 41 to insert along the liquid outlet gap of the grid 11, and a swing assembly 43 for driving the clogging cleaning mechanism 4 to swing up and down along the grid gap; one side of the rotating unclogging assembly 41 is movably connected with the swing assembly 43; the hydraulic power assembly 42 is fixed on the moving trolley 32, and the output end of the hydraulic power assembly 42 is connected with the swing assembly 43.

[0066] The clogging cleaning mechanism 4 is carried on the moving trolley 32, the moving trolley 32 moves along the length direction of the grid 11 to align the rotating unclogging assembly 41 (such as an unclogging rod with helical teeth) with the adjacent grid 11 rail gap (liquid outlet gap) to be cleaned; during the positioning process, the system is calibrated by a visual sensor or a limit switch to ensure that the axis of the rotating unclogging assembly 41 is aligned with the central axis of the grid liquid outlet gap. After the positioning is completed, the hydraulic power assembly 42 fixed on the moving trolley 32 is started, the output end (hydraulic push rod) thereof extends to the grid 11, drives the swing assembly 43 and the rotating unclogging assembly 41 connected therewith to move synchronously; the hydraulic power assembly 42 can provide stable thrust to push the rotating unclogging assembly 41 to insert along the axial direction of the grid liquid outlet gap into the clogging area (the insertion depth is adjusted according to the thickness of the grid), so as to ensure that the assembly can contact the fiber winding garbage or viscous residue in the deep part of the gap. After the rotating unclogging assembly 41 is inserted into position, the built-in driving motor (or hydraulic motor) is started to drive the unclogging rod and the surface helical teeth to rotate at high speed; during the rotating process, the helical teeth can strip the stubborn clogging materials (such as plastic bag winding and food residue lump) attached in the grid liquid outlet gap from the rail surface through shearing and scraping, and at the same time, the axial thrust generated by the rotating unclogging assembly 41 can transport the stripped clogging materials outward to avoid the secondary accumulation of the clogging materials in the gap. While the rotating unclogging is performed, the swing assembly 43 is started to drive the rotating unclogging assembly 41 to swing up and down (swing angle range 0°-45°) around the movable connection point of the swing assembly; during the swinging process, the helical teeth of the rotating unclogging assembly 41 can cover the side wall and the corner dead angle of the grid liquid outlet gap to further scrape the small clogging materials remaining in the liquid outlet gap; when the swing angle reaches 45°, the lateral scraping force on the grid rail can loosen the hardened residue in the liquid outlet gap to ensure that there is no clogging material attached in the liquid outlet gap. After the clogging is cleaned, the rotating unclogging assembly 41 stops rotating, the swing assembly 43 is reset to the initial angle (0°), the hydraulic power assembly 42 drives the output end to retract, and drives the rotating unclogging assembly 41 to exit from the grid gap; then the moving trolley is moved to the liquid outlet gap of the next grid 11 to be cleaned by the transverse driving mechanism 3, and the above process is repeated to realize the continuous clogging cleaning of the liquid outlet gaps of the grids 11.

[0067] Specifically, the rotating dredging assembly 41 comprises a mounting plate 411, at least two groups of dredging columns 412, and a driving motor 413. On the front surface of the mounting plate 411, the number of the dredging columns 412 can be increased to three or more according to the height of the grating 11. Each of the dredging columns 412 is arranged in a direction perpendicular to the plane of the grating 11, and the spacing thereof corresponds to the spacing of the gaps of the grating 11, so as to ensure that each of the dredging columns 412 can be accurately aligned with a gap of the grating 11.

[0068] Specifically, the mounting plate 411 is welded by high-strength steel, and the back surface of the mounting plate 411 is fixedly connected with the output end of the hydraulic power assembly 42 through a flange. The main body of each of the dredging columns 412 is a solid alloy steel rod, the surface of which is subjected to special hardening treatment, and has extremely high wear resistance and corrosion resistance. The axis of each group of the dredging columns 412 is perpendicular to the plane of the grating, so as to ensure that the dredging columns 412 can be accurately aligned with the gaps of the grating. Both ends of each of the dredging columns 412 are provided with a sprocket, and the dredging columns 412 in the same row are connected in series through a closed chain, so as to form a synchronous transmission structure of one chain and multiple columns, thereby being capable of generating the best gnawing and conveying effect during rotation. The driving motor 413 is fixed on the side of the mounting plate 411, and a driving sprocket is mounted on the output shaft of the driving motor 413. The driving sprocket is connected with a driven sprocket of one of the dredging columns through a chain. When the driving motor 413 operates, power can be transmitted to the chain through the driving sprocket, and the chain drives the driven sprockets of all the dredging columns to rotate synchronously, so as to ensure the synchronization of power transmission.

[0069] In the embodiment, as shown in Figure 11 and Figure 12 each of the groups of the dredging columns 412 is welded with a helically inclined dredging tooth 4121 on the outer peripheral surface thereof, and the tooth spacing of the dredging tooth 4121 matches the gap width of the grating 11.

[0070] Specifically, the dredging tooth 4121 is continuously wound in a helical line on the column body, and the tooth spacing of the dredging tooth 4121 is precisely calculated and is smaller than the gap width of the grating 11. When the dredging column 412 rotates and approaches the grating 11, the helically inclined dredging tooth 4121 will first contact the blocked garbage at the gap of the grating 11. Since the dredging tooth 4121 is helically distributed, each turn of the dredging tooth 4121 will generate a continuous force on the garbage, so as to ensure that the garbage can be fully broken, and large pieces of garbage are avoided. At the same time, the design of the obtuse blade edge of the dredging tooth 4121 can reduce the cutting effect on fiber garbage, and prevent the fiber from winding on the teeth. With the continuous rotation and advancement of the dredging column 412, the dredging tooth 4121 will generate a squeezing and tearing force on the garbage. For the hardened garbage, the side surface of the dredging tooth 4121 will squeeze the garbage block, so that the block is cracked and broken. For the loose garbage, the dredging tooth 4121 will hook and tear the garbage into small pieces.

[0071] It should be noted that the helical inclined dredging teeth 4121 will generate a component force along the axis direction of the dredging column 412 when rotating, and the direction of the component force is opposite to the grid 11, which can transport the broken garbage away from the grid 11. This conveying effect can prevent the broken garbage from re-accumulating at the gap of the grid 11, preventing secondary blockage; at the same time, the continuous helical dredging teeth 4121 can form a conveying channel to ensure that the garbage can be stably conveyed to the designated area. Since the tooth spacing of the dredging teeth 4121 matches the gap width of the grid 11, the teeth will penetrate into the gap of the grid 11 when rotating, and remove small blockages such as silt and small particle kitchen garbage in the gap. At the same time, the helical tooth distribution can form a scraping effect in the gap, which can clean the garbage attached to the inner wall of the gap, and ensure that the drainage function of the gap of the grid 11 is fully restored.

[0072] In the present embodiment, as shown in Figure 12 and Figure 13 each dredging column 412 is detachably connected with a piercing head 4122 at one end towards the garbage bin 1 by screw thread; the piercing head 4122 is conical, barbed or helical.

[0073] Specifically, the three types of piercing heads 4122 can respectively deal with hard and solidified garbage, fiber garbage and dense clumps of garbage, avoiding the problem of ineffective piercing due to the difference in types of blockages; for example, a conical piercing head is selected for processing of solidified kitchen garbage, a barbed piercing head is selected for processing of plastic film winding, and a helical piercing head is selected for processing of mixed garbage dense clumps, to ensure efficient breakthrough of garbage structure in different scenarios. The piercing head 4122 in the present embodiment is preferably conical. The conical piercing head 4122 can quickly penetrate when rotating, making it easier to penetrate into the interior of the solidified and hard garbage clumps, thereby opening up a channel for the subsequent dredging teeth 4121 operation; when the piercing head 4122 penetrates into the garbage clumps to a certain depth, the helical inclined dredging teeth 4121 on the outer periphery of the dredging column 412 will follow up to further break and transport the garbage clumps damaged by the piercing head 4122, to ensure that the solidified garbage can be efficiently removed.

[0074] It is worth noting that, due to the large number of garbage types in the garbage bin 1, different types of garbage are prone to entanglement, solidification and other problems when they are stacked together, and are extremely easy to stick or entangle on the dredging column 412 during the dredging process of the rotating dredging assembly 41, thereby affecting the subsequent dredging effect. Therefore, in order to avoid the dredging column 412 being entangled by garbage during dredging, a corresponding elastic scraping strip 44 is arranged below the dredging column 412, and the number of elastic scraping strips 44 corresponds to the number of rows of dredging columns 412; each group of elastic scraping strips 44 is fixedly installed on the mounting plate 411 by bolts, and the top end of the elastic scraping strip 44 is processed with a wedge-shaped structure which closely fits the surface of the rotating dredging column 412.

[0075] Specifically, the elastic scraping strip is made of polyurethane or other materials with high elasticity, high wear resistance and self-lubricating properties; when the carrier of the unblocking column 412 rotates to the position of the elastic scraping strip, the wedge-shaped structure can effectively scrape off the garbage adhered and wound on the unblocking teeth 4121. The elastic design ensures that the elastic scraping strip can effectively scrape without rigid interference and wear with the unblocking column 412, prolonging the service life of both, thereby greatly reducing the time for stopping and cleaning the wound objects, ensuring the continuous and efficient operation of the unblocking column 412, and reducing equipment jamming and maintenance frequency.

[0076] In this embodiment, as shown in Figure 9 and Figure 10 , the hydraulic power assembly 42 includes a fixed base 421, a hydraulic pump 422 and a hydraulic cylinder 423, the fixed base 421 is installed on the moving trolley 32; the hydraulic pump 422 and the hydraulic cylinder 423 are installed in the fixed base 421, and the hydraulic pump 422 and the hydraulic cylinder 423 are connected through a hydraulic pipeline; the piston rod of the hydraulic cylinder 423 is connected with the rotating unblocking assembly 41 through the swing assembly 43, for driving the swing assembly 43 and the rotating unblocking assembly 41 to move back and forth.

[0077] The swing assembly 43 includes a hinged seat 431, a swing cylinder 432 and a swing rod 433, the swing cylinder 432 is installed on the output end of the hydraulic cylinder 423 through a mounting seat, and the delivery end of the swing cylinder 432 is hinged with one end of the connecting rod 434; the other end of the connecting rod 434 is hinged with the hinged seat 431; the hinged seat 431 is fixed on the mounting seat; one end of the swing rod 433 is hinged with the middle part of the connecting rod 434, and the other end is hinged with the mounting plate 411.

[0078] Specifically, by controlling the extension and retraction of the swing cylinder 432, the connecting rod 434 can be pulled to move, thereby driving the swing rod 433 to swing at a certain angle with the hinged seat 431 as the center, which is set to 0°-45° in this embodiment; the extension and retraction of the swing cylinder 432 can realize the up and down swing of the swing rod 433, thereby driving the rotating unblocking assembly 41 to cover the upper, middle and lower areas of the grid, avoiding the problem of local blockage and residue, for example, the lower part of the grid 11 is easy to accumulate kitchen waste with high density, and the upper part is easy to wind fiber waste; the swing assembly 43 can ensure that the blockage in these areas can be cleaned, thereby improving the overall unblocking effect of the grid 11. In addition, when the unblocking column 412 is initially inserted, a small swing can make the hardened garbage be broken and loosened more effectively, and the clearing effect is much better than that of simple linear motion; and the swing action can imitate the action of manually unblocking with an iron rake, and can comb the surface of the grid 11, so that the cleaning coverage is wider.

[0079] It can be understood that, for those ordinary skilled in the art, equivalent replacements or changes can be made according to the technical solutions and the inventive concept of the present application, and all the changes or replacements shall fall within the protection scope of the appended claims of the present application.
