Abstract

This invention relates to the field of sanitation vehicle technology and discloses an automatic bin lifting and positioning structure for rural sanitation vehicles. The structure includes a tilting mechanism, which comprises a flipping assembly. The flipping assembly has a pair of opposing clamping switching components for guiding the bin into the clamping area when approaching the work station at low speed. Each clamping switching component includes a moving plate and a rectangular nozzle. A row of ball bearings is rolled on the moving plate. This invention, by setting a moving plate with ball bearings on the clamping switching assembly, and driving the moving plate to press against the bin wall and restricting the ball bearings from continuing to roll after the bin is moved to a predetermined position, allows the bin to achieve controlled sliding and posture alignment during the initial clamping stage through low-friction contact and its own weight.

Description

Technical Field

[0001] This invention belongs to the field of sanitation vehicle technology, and particularly relates to an automatic bucket lifting and positioning structure for rural sanitation vehicles. Background Technology

[0002] In the collection and transportation of rural domestic waste, especially in mobile collection and transportation operations in village roads, alleys and scattered residential areas of farmers, sanitation vehicles usually need to approach the garbage bins one by one along the collection route and use the bin-hanging mechanism installed on the sanitation garbage bins to complete the introduction, clamping, lifting and tipping of the garbage bins.

[0003] In rural decentralized collection scenarios, garbage bins are mostly placed on roadsides, at village entrances, around courtyards, or near temporary collection points. The relative positions between bins and vehicles are often inconsistent. Vehicles are also affected by road width, parking space, and road conditions, making it difficult to maintain high alignment accuracy in every operation. For this scenario, the bin-lifting mechanism needs to do more than just lift the garbage bins. More importantly, it needs to ensure that the garbage bins can smoothly enter the clamping area when receiving them at low speed, and quickly form a relatively stable force state after entering. Otherwise, it will directly affect the continuity of subsequent lifting and tipping operations.

[0004] Existing vehicle-mounted bin-lifting structures can complete basic bin-lifting and tipping operations when the bins are placed correctly and the vehicle and bins are well aligned. However, in the aforementioned low-speed bin-receiving conditions in rural areas, when the bins enter the clamping area, there is a certain degree of tilt, or there is a lateral or angular deviation between the bin and the vehicle. In the initial clamping stage, the bins are prone to one-sided contact, posture shift, or uneven force, which leads to unstable clamping in the initial lifting and lowering stage and affects the smooth progress of subsequent tipping and tipping. Especially for vehicle-mounted operations that require first guiding, then clamping, and then tipping, whether the posture of the bins can be adjusted in time after entering the clamping area will directly affect the stability and reliability of subsequent bin-lifting operations. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic bin lifting and positioning structure for rural sanitation vehicles, which solves the technical problem in the prior art that garbage bins are prone to tilting after entering the clamping area under the conditions of decentralized collection and transportation in rural areas and low-speed approach to the bin position by vehicles, resulting in unstable clamping in the initial stage of lifting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic bin lifting and positioning structure for rural sanitation vehicles includes a tilting mechanism installed on a sanitation garbage bin. The tilting mechanism is used to tilt garbage from the bin into the sanitation garbage bin. The tilting mechanism includes a flipping component with a pair of opposing clamping switching components for guiding the garbage bin into the clamping area when approaching the work station at low speed. The clamping switching component includes a moving plate with a row of ball bearings rolled on it. When the garbage bin is initially clamped, the ball bearings form a low-friction contact with the bin wall, allowing the garbage bin to slide and be guided in a controlled manner under its own weight during the initial lifting and lowering process. The clamping switching component also includes a rectangular nozzle. When the garbage bin continues to move upward after being guided by the ball bearings, the rectangular nozzle abuts against the outer wall of the garbage bin relative to the moving plate and presses against it, causing the ball bearings to gradually exit the main guiding force state. This switches the clamping switching component from the guiding state to a rigid clamping state, and the bin continues to be lifted and flipped in this rigid clamping state.

[0007] According to some embodiments, the tilting mechanism further includes a clamping and straightening assembly, which includes: a mounting box on which two first threaded blocks are fixedly mounted; a positive and negative screw, rotatably mounted on the mounting box, with a first threaded seat that is slidably connected to the mounting box at both its positive and negative ends; and a third motor, fixedly mounted on the mounting box, with its power output shaft fixedly connected to the positive and negative screw.

[0008] According to some embodiments, the clamping and aligning assembly further includes: a second rotating shaft, rotatably mounted on the first threaded seat, on which a rotating block connected to the clamping switching assembly is mounted; a torsion spring, sleeved on the second rotating shaft, with both ends of the torsion spring connected to the first threaded seat and the rotating block respectively, to provide a torsional preload to the rotating block, thereby causing the clamping switching assembly to rotate torsionally in a preset direction around the second rotating shaft.

[0009] According to some embodiments, the clamping and aligning assembly further includes: a fixed cover, fixedly mounted on the first threaded seat, on which a second screw is rotatably mounted; a worm gear, fixedly mounted on the second screw; a worm, on which a rotating seat fixedly connected to the fixed cover is rotatably mounted; a pressing plate, threadedly connected to the second screw and slidably connected to the fixed cover, for limiting the torque rotation of the clamping switching assembly; a first gear, fixedly mounted on the worm; and a toothed plate, fixedly mounted on the mounting box, with only two ends provided with locking teeth that mesh with the first gear.

[0010] According to some embodiments, the clamping switching assembly further includes: a clamping box, which is fixedly connected to the rotating block and slidably connected to the moving plate; and a second spring, one end of which is fixedly connected to the clamping box and the other end of which is fixedly connected to the moving plate.

[0011] According to some embodiments, the rectangular nozzle is slidably mounted on the clamping box and connected to the clamping box by a plurality of third springs; the clamping switching assembly further includes: a plurality of first protrusions, respectively fixedly mounted on the moving plate and the rectangular nozzle; a slide rod, slidably mounted on the clamping box, with a compression cover fixedly mounted on the outer part of the slide rod and a compression ball fixedly mounted on the inner part of the slide rod; and a first spring, one end of which is fixedly connected to the compression cover and the other end of which is fixedly connected to the clamping box.

[0012] According to some embodiments, the dumping mechanism further includes a tilting assembly, which includes: a plurality of first rotating shafts, all rotatably mounted on the sanitation waste bin, each with a rotating plate fixedly mounted thereon; a mounting frame, fixedly mounted on the sanitation waste bin; and a first motor, fixedly mounted on the mounting frame, with its power output shaft fixedly connected to the first rotating shafts.

[0013] According to some embodiments, the flipping assembly further includes: a fixed frame, fixedly connected to the first rotating shaft, on which two sliding seats are slidably mounted; a first screw, rotatably mounted on the two sliding seats and threadedly connected to the first threaded block; a second motor, fixedly mounted on the sliding seats, with its power output shaft fixedly connected to the first screw; and an electric push rod, fixedly mounted on the fixed frame, with its telescopic end fixedly connected to the sliding seats.

[0014] According to some embodiments, the tilting mechanism further includes a cleaning assembly, which includes: a storage box, fixedly installed at the bottom of the clamping box; a metering pump, fixedly installed at the bottom of the inner cavity of the storage box; and a delivery pipe, fixedly installed on the clamping box, with one end connected to the rectangular nozzle and the other end connected to the metering pump.

[0015] According to some embodiments, the tilting mechanism further includes a triggering component, which includes: a second protrusion fixedly installed at the bottom end of the first threaded seat; a mounting tube fixedly installed on the storage box, with a trigger switch fixedly installed inside; a squeezing rod slidably installed on the mounting tube; and a fourth spring located inside the squeezing rod, with one end connected to the mounting tube and the other end connected to the squeezing rod.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention provides a movable plate with ball bearings on the clamping and switching assembly. After the trash can is moved to a predetermined position, the movable plate is driven to press against the can wall and restrict the ball bearings from continuing to roll. This allows the trash can to achieve controlled sliding and posture alignment during the initial clamping stage by means of low-friction contact and its own weight. In the subsequent lifting and flipping stage, it promptly switches to a rigid clamping state, thus taking into account both the alignment requirements when receiving the trash can and the clamping stability when flipping the trash can, reducing clamping instability and detachment caused by the tilt of the trash can.

[0017] 2. This invention, by setting up a clamping and aligning component, allows the two left and right clamping switching components to unfold in opposite directions to form a figure-eight-shaped inlet before receiving the trash can. This improves the adaptability to lateral and angular deviations of the trash can. During subsequent adjustment, under the limiting action of the squeezing plate, it is gradually adjusted to a clamping posture that is approximately perpendicular to the mounting box, which facilitates symmetrical clamping of the trash can. This helps to reduce the alignment requirements during low-speed trash can receiving and reduces the risk of collision, jamming, and trash can falling.

[0018] 3. By placing the storage box, metering pump, and delivery pipe on the clamping box, and spraying the cleaning medium through a rectangular nozzle onto the clamping working area and the part of the garbage can to be clamped, this invention can pre-clean the area of ​​the garbage can wall that comes into contact with the ball bearings, moving plate, and subsequent clamping components during the hanging operation. This reduces the impact of mud, dust, and dirt on the guiding, pressing, and clamping actions, thereby improving the clamping contact conditions, reducing slippage and unstable force, and improving the stability of the device during continuous operation.

[0027] Example 1: As Figures 1 to 9 As shown, this embodiment provides an automatic hanging bin lifting and positioning structure for rural sanitation vehicles, which is installed on the sanitation garbage bin 100. The whole includes a tilting mechanism 200, which includes a flipping component 210, a clamping and straightening component 220, a clamping and switching component 230, a cleaning component 240 and a triggering component 250, used to guide, straighten, clamp, lift, flip and tilt the garbage bin 300.

[0028] The dumping mechanism 200 is installed on the sanitation garbage bin 100 and is used to lift and dump the garbage in the garbage bin 300 into the sanitation garbage bin 100. The dumping mechanism 200 includes a flipping component 210, which serves as the load-bearing assembly of the entire bin lifting and flipping mechanism. A clamping and switching component 230 is provided at its lower part so that when the sanitation vehicle approaches the garbage bin 300 station at low speed, the garbage bin 300 is first guided into the clamping area before the subsequent lifting and flipping actions are performed.

[0029] The clamping switching assembly 230 includes a movable plate 235 on which a row of balls 236 are rolled. The movable plate 235 serves as the main load-bearing component that interacts with the wall of the trash can 300, and the balls 236 form the rolling contact interface on the front side of the movable plate 235. When the trash can 300 first enters the clamping area and comes into contact with the clamping switching assembly 230, the balls 236 preferentially contact the wall of the trash can, thereby forming a low-friction rolling contact relationship between the trash can 300 and the clamping switching assembly 230. With this structure, the trash can 300 can slide in a controlled manner relative to the balls 236 under its own weight during the initial lifting and lowering process, thereby achieving automatic alignment of the can body and avoiding subsequent clamping instability due to initial tilt of the can body.

[0030] Furthermore, when the trash can 300 continues to move upward with the flipping component 210 and reaches the predetermined position, the clamping switching component 230 is triggered, thereby driving the moving plate 235 to press further against the trash can 300 wall, while restricting the retraction of the ball bearing 236, causing the clamping switching component 230 to switch from the initial guiding state to the later rigid clamping state. This action path of first guiding with rolling and then rigid clamping reduces friction and improves the alignment ability in the initial receiving stage, while also improving clamping stability and preventing detachment during the flipping stage. (See [link to relevant documentation]). Figure 1 and Figure 5 .

[0031] During operation, the tilting mechanism 200 drives the tilting component 210 to approach the location of the trash can 300. After the trash can 300 enters the clamping area, it first contacts the ball bearings 236 on the moving plate 235. Since the ball bearings 236 can roll, the trash can 300 forms a low-friction contact relationship with the clamping switching component 230 in the initial clamping stage. Subsequently, the tilting component 210 lifts the trash can 300. In the initial lifting stage, the trash can 300 slides in a controlled manner along the ball bearings 236 under its own weight, thereby automatically adjusting its posture and gradually straightening itself. After the trash can 300 continues to move upward to the predetermined trigger position, the moving plate 235 is driven to press further against the can wall and restrict the ball bearings 236 from continuing to roll, so that the clamping switching component 230 changes from the guiding state to the rigid clamping state. In this state, the tilting component 210 continues to complete the lifting and tilting actions.

[0032] See Figures 3 to 5As shown, the tilting mechanism 200 also includes a clamping and leveling assembly 220; the clamping and leveling assembly 220 includes a mounting box 222, on which two first threaded blocks 221 are fixedly mounted for use in conjunction with the subsequent flipping assembly 210 to achieve overall position adjustment; a positive and negative screw 224 is rotatably mounted on the mounting box 222, the two ends of the positive and negative screw 224 have opposite thread directions, and the positive and negative ends are respectively threaded to two first threaded seats 2293 that are slidably connected to the mounting box 222; therefore, when the positive and negative screw 224 rotates, the two first threaded seats 2293 can move synchronously towards each other or away from each other to achieve synchronous opening and closing of the clamping structure on both sides; a third motor 223 is fixedly mounted on the mounting box 222, and the power output shaft of the third motor 223 is fixedly connected to the positive and negative screw 224 to provide driving force for the above-mentioned synchronous adjustment action; a second rotating shaft 2294 is rotatably mounted on each first threaded seat 2293, and a clamping and leveling switch is mounted on the second rotating shaft 2294. The rotating block 2295 is connected to component 230; thus, the translation of the first threaded seat 2293 can drive the rotating block 2295 and its connected clamping switching component 230 to move synchronously closer to or away from the trash can 300; at the same time, a torsion spring 2296 is sleeved on the second rotating shaft 2294, and the two ends of the torsion spring 2296 are respectively connected to the first threaded seat 2293 and the rotating block 2295. With the help of the torsion spring 2296, a pre-tightening torque is continuously applied to the rotating block 2295 to swing outward, so that the two clamping switching components 230 in the initial state deflect and unfold around the corresponding second rotating shaft 2294 in opposite directions, thereby forming a figure-eight pre-opening inlet between them; through this setting, a larger inlet opening can be formed when the trash can 300 approaches, enhancing the adaptability to lateral and angular deviations of the can body, making it easier for the trash can 300 to enter the clamping area, and providing a more stable initial posture for the subsequent rolling guidance and rigid clamping of the clamping switching component 230.

[0033] See Figure 3 and Figure 4As shown, a fixed cover 225 is also fixedly installed on the first threaded seat 2293. A second screw 227 is rotatably installed on the fixed cover 225. A worm gear 226 is fixedly installed on the second screw 227. A worm 228 that cooperates with the worm gear 226 is also installed on the fixed cover 225. The worm 228 is mounted on the fixed cover 225 via a rotating seat. A first gear 229 is fixedly installed on the worm 228. A toothed plate 2291 is fixedly installed on the mounting box 222. The first gear 229 meshes with the snap teeth provided at the end of the toothed plate 2291, thereby forming a controlled meshing transmission. The pressing plate 2292 is threadedly connected to the second screw 227 and cooperates with the fixed cover 225. When the second screw 227 rotates, it moves in a set direction to limit the torque rotation of the clamping switching assembly 230. Preferably, the threads of the two second screws 227 are opposite, so that the corresponding two extrusion plates 2292 can move closer or further away from each other synchronously, so as to achieve consistent adjustment of the limiting state of the left and right clamping switching components 230.

[0034] After the third motor 223 starts, it drives the positive and negative screws 224 to rotate. Since the threads at both ends of the positive and negative screws 224 are in opposite directions, the two first threaded seats 2293 connected to them move synchronously towards or away from each other along the mounting box 222, thereby driving the clamping structure on both sides to open and close synchronously. During the movement of the first threaded seats 2293, the second rotating shaft 2294 provides a pivot point for the rotating block 2295, and the torsion spring 2296 sleeved on the second rotating shaft 2294 continuously applies a torsional preload to the rotating block 2295, causing the clamping switching assembly 230 to deflect and unfold in opposite directions, thereby forming a figure-eight pre-opening inlet between the two. At the same time, the movement of the two first threaded seats 2293 will cause the first gear 229 to move together. The engagement of the first gear 229 with the end teeth of the gear plate 2291 will cause the worm 228 to rotate, thus the meshing action between the worm 228 and the worm wheel 226. The second screw 227 is driven to rotate, which in turn causes the extrusion plate 2292 to move along the axial direction of the second screw 227, mechanically limiting the swing amplitude of the clamping switching assembly 230. In this way, the figure-eight-shaped inlet formed by the two clamping switching assemblies 230 can be used to increase the inlet coverage of the garbage can 300 in the early stage, reducing the alignment accuracy requirements when the vehicle approaches at low speed. In the later stage, under the limiting action of the extrusion plate 2292, the two clamping switching assemblies 230 can be stably adjusted to a clamping posture that is approximately perpendicular to the mounting box 222, which facilitates symmetrical clamping of the garbage can 300, thereby improving clamping stability and reducing the risk of collision, jamming and dropping.

[0035] See Figure 5 and Figure 6As shown, the clamping switching assembly 230 includes a clamping box 234, which is fixedly connected to the rotating block 2295, so that it can rotate synchronously with the rotating block 2295. At the same time, the clamping box 234 is slidably connected to the moving plate 235. A second spring 237 is provided between the clamping box 234 and the moving plate 235. One end of the second spring 237 is fixedly connected to the clamping box 234, and the other end is fixedly connected to the moving plate 235, which is used to apply an elastic restoring force to the moving plate 235.

[0036] A rectangular nozzle 2391 is also slidably mounted on the clamping box 234. The rectangular nozzle 2391 is connected to the clamping box 234 through multiple third springs 239, so that the rectangular nozzle 2391 has elastic displacement capability relative to the clamping box 234. Multiple first protrusions 2392 are fixedly mounted on the moving plate 235 and the rectangular nozzle 2391 respectively.

[0037] A sliding rod 232 is also slidably mounted on the clamping box 234. A compression cover 231 is fixedly mounted on the outer part of the sliding rod 232, and a compression ball 238 is fixedly mounted on the inner part of the clamping box 234. The compression cover 231 serves as an external contact component, and its top is covered with a rubber layer so that it can preferentially contact or be compressed with the trash can 300 during the initial clamping process. The sliding rod 232 transmits the external force to the inside of the clamping box 234. The compression ball 238 is used to transmit the force to the two first protrusions 2392. A first spring 233 is also provided between the sliding rod 232 and the clamping box 234. One end of the first spring 233 is fixedly connected to the compression cover 231, and the other end is fixedly connected to the clamping box 234, which is used to provide elastic reset for the compression cover 231 and the sliding rod 232.

[0038] After the trash can 300 enters the clamping area and is initially guided by the ball bearing 236, as the clamping switching assembly 230 continues to move upward, the outer wall of the trash can 300 squeezes the compression cover 231. The compression cover 231 drives the slide rod 232 to move inward to the clamping box 234. The compression ball 238 at the inner end of the slide rod 232 changes the force on the two first protrusions 2392, causing the moving plate 235, which was originally in the extended guiding state, to retract inward to the clamping box 234 with the cooperation of the second spring 237. Meanwhile, the rectangular nozzle 2391 remains extended and close to the outer wall of the trash can 300 under the combined action of the third spring 239 and the compression ball 238. This causes the ball bearing 236 to exit the main force-bearing position, and the clamping switching assembly 230 changes from the guiding state to the rigid clamping state to ensure the clamping stability of the trash can 300 during subsequent lifting and flipping processes.

[0039] See Figure 1 and Figure 2As shown, the tipping mechanism 200 also includes a tilting assembly 210; the tilting assembly 210 includes multiple first rotating shafts 214, a mounting bracket 211, a first motor 212, a fixing frame 215, a first screw 216, a second motor 217, and two sliding seats 219. The multiple first rotating shafts 214 are rotatably mounted on the sanitation waste bin 100, serving as rotational support components for the tilting assembly 210; the mounting bracket 211 is fixedly mounted on the sanitation waste bin 100 to support the first motor 212; the first motor 212 is fixedly mounted on the mounting bracket 211, and its power output shaft is fixedly connected to the first rotating shafts 214 to provide tilting power to the tilting assembly 210.

[0040] The fixed frame 215 is fixedly connected to the first rotating shaft 214, so the fixed frame 215 can rotate synchronously with the rotation of the first rotating shaft 214. Two sliding seats 219 are slidably mounted on the fixed frame 215. A first screw 216 is rotatably mounted on the sliding seat 219. The first screw 216 is threadedly connected to the first threaded block 221, so that when the first screw 216 rotates, it can drive the mounting box 222 and its structure to adjust its position relative to the fixed frame 215. A second motor 217 is fixedly mounted on the sliding seat 219, and its power output shaft is fixedly connected to the first screw 216 to drive the first screw 216 to rotate. An electric push rod 218 is fixedly mounted on the fixed frame 215, and its telescopic end is fixedly connected to the sliding seat 219 to drive the sliding seat 219 to slide along the fixed frame 215. This allows the clamping switching assembly 230 to move upward as a whole, so that the compression cover 231 and the garbage can 300 squeeze each other until the moving plate 235 and the rectangular nozzle 2391 switch to form a stable clamp. Through the above structure, the flipping assembly 210 not only undertakes the subsequent lifting and flipping function, but also undertakes the clamping mechanism adjustment function before receiving the garbage can.

[0041] During operation, before or during the receiving of the garbage bin, the second motor 217 drives the first screw 216 to rotate. Since the first screw 216 is threadedly connected to the first threaded block 221, the mounting box 222 and the clamping structure it carries can be adjusted in position relative to the fixed frame 215 in a set direction. The two sliding seats 219 provide support and guidance for the first screw 216 and the second motor 217. After the two moving plates 235 clamp the garbage bin 300, the two moving plates 235 can be moved upward by the electric push rod 218 until the compression cover 231 and the garbage bin 300 are squeezed against each other. The moving plates 235 and the rectangular nozzle 2391 switch to form a stable clamp. Finally, the first motor 212 outputs power to drive the first rotating shaft 214 to rotate. The first rotating shaft 214 drives the fixed frame 215 to rotate around the set axis, thereby realizing the lifting and flipping action of the garbage bin 300.

[0042] The working principle of this embodiment: The tilting mechanism 200 on the sanitation garbage bin 100 starts working. The flipping component 210 first drives the clamping and straightening component 220, the clamping switching component 230, the cleaning component 240, and the triggering component 250 to move closer to the work position of the garbage bin 300. The second motor 217 on the mounting frame 211 first drives the first screw 216 to rotate, so that the mounting box 222 completes the initial adjustment with the cooperation of the first threaded block 221. The two sliding seats 219 play a guiding role in this process. Then the third motor 223 drives the forward and reverse screws 224 to rotate, so that the two first threaded seats 2293 move synchronously towards or away from each other. The rotating block 2295 on the second rotating shaft 2294 drives the clamping switching components 230 on both sides to deflect outward to form an introduction space under the continuous action of the torsion spring 2296. The first gear 229 drives the worm 228 to rotate under the action of the toothed plate 2291. The worm wheel 226 and the second screw 227 move accordingly, so that the squeezing plate 2292 gradually moves forward. The position is changed to control the swing amplitude of the clamping switching component 230, gradually adjusting it from the inlet posture to the clamping posture. After the trash can 300 enters, the moving plate 235 inside the clamping box 234 remains extended under the action of the squeezing ball 238. The ball bearing 236 first contacts the can wall and rolls to guide its alignment. Then, the electric push rod 218 pushes the sliding seat 219 to continue running, causing the compression cover 231 to be compressed, which in turn drives the sliding rod 232 and the squeezing ball 238 to move inward. The first spring 233 lifts... The compression ball 238 provides a restoring force, and then drives the moving plate 235 and the rectangular nozzle 2391 to switch through the first protrusion 2392. Under the action of the compression ball 238, the rectangular nozzle 2391 cooperates to stick to the wall of the bin. The moving plate 235, together with the ball bearing 236, gradually returns to the clamping box 234. The first motor 212 drives multiple first rotating shafts 214 and rotating plate 213 to rotate, and the fixed frame 215 flips accordingly, thereby completing the introduction, alignment, clamping, lifting and dumping of the garbage bin 300.

[0043] Example 2: Figures 3 to 9 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that: The trigger assembly 250 includes a second protrusion 252, a mounting tube 251, a pressing rod 253, a fourth spring 254, and a trigger switch 255. The second protrusion 252 is fixedly mounted on the bottom end of the first threaded seat 2293 and moves synchronously with the displacement of the first threaded seat 2293. The mounting tube 251 is fixedly mounted on the storage box 241, and the trigger switch 255 is fixedly installed inside it. The pressing rod 253 is slidably mounted inside the mounting tube 251 and is an actuator that directly cooperates with the second protrusion 252. The fourth spring 254 is located inside the pressing rod 253, with one end connected to the mounting tube 251 and the other end connected to the pressing rod 253, and is used to push the pressing rod 253 to reset after being pressed. A clear positioning trigger relationship can be formed through the mechanical contact between the second protrusion 252 and the pressing rod 253.

[0044] When the first threaded seat 2293 moves to be perpendicular to the mounting box 222, the second protrusion 252 at its bottom end further compresses the extrusion rod 253 in the mounting tube 251 and pushes the extrusion rod 253 to move axially along the mounting tube 251. During this process, the fourth spring 254 is compressed, and the extrusion rod 253 continues to move inward and triggers the trigger switch 255 inside the mounting tube 251, thereby enabling the cleaning assembly 240 to clean the outer surface of the trash can 300.

[0045] The cleaning assembly 240 includes a storage box 241, a metering pump 242, and a delivery pipe 243. The storage box 241 is fixedly installed at the bottom of the clamping box 234 and is used to store the cleaning medium, such as clean water. The metering pump 242 is fixedly installed at the bottom of the inner cavity of the storage box 241 and is used to extract a metered amount of cleaning medium from the storage box 241 as needed. The delivery pipe 243 is fixedly installed on the clamping box 234, with one end connected to a rectangular nozzle 2391 and the other end connected to the metering pump 242, for delivering the cleaning medium extracted by the metering pump 242 to the rectangular nozzle 2391. By directly mounting the cleaning assembly 240 on the clamping box 234, the cleaning area and the clamping working area can be arranged adjacent to each other, facilitating cleaning as needed during operation.

[0046] When cleaning of the clamping work area is required, the cleaning medium in the storage box 241 is extracted by the metering pump 242 and transported to the rectangular nozzle 2391 via the delivery pipe 243. The rectangular nozzle 2391 then sprays and cleans the work area near the clamping box 234. Since the storage box 241 is located at the bottom of the clamping box 234, the metering pump 242 is located at the bottom of the storage box 241, and the delivery pipe 243 directly connects the metering pump 242 and the rectangular nozzle 2391, the cleaning path is shorter and the medium is delivered more directly. This reduces the accumulation of mud, dust, or dirt in the clamping area and allows for pre-cleaning of the outer wall of the trash can 300, especially the area that will subsequently come into contact with the ball bearing 236 and the moving plate 235. Cleaning the surface of the trash can 300 to be clamped reduces the impact of mud and dirt adhering to the can wall on the rolling guidance of the ball bearing 236, the pressing and contacting of the moving plate 235, and the subsequent clamping action of the clamping switching assembly 230, thus avoiding slippage, deviation, or unstable contact during clamping. At the same time, it also reduces the accumulation of dirt in the working area in front of the rectangular nozzle 2391, preventing the rectangular nozzle 2391 from being blocked or interfered with by dirt when it moves close to the trash can 300. This facilitates the subsequent stable clamping of the trash can 300 by the clamping switching assembly 230 and improves the reliability and continuous operation stability when switching from the guiding state to the rigid clamping state.

[0047] The working principle of this embodiment: When the first threaded seat 2293 moves to the predetermined clamping posture, the second protrusion 252 contacts the extrusion rod 253 in the mounting tube 251 and pushes the extrusion rod 253 to move axially inward along the mounting tube 251. The fourth spring 254 is compressed during this process. When the extrusion rod 253 moves to the set stroke, the trigger switch 255 is activated and controls the metering pump 242 to start. The cleaning medium in the storage box 241 is transported to the rectangular nozzle 2391 through the delivery pipe 243 and sprayed out to pre-clean the area to be clamped and the clamping working area of ​​the garbage can 300. When the second protrusion 252 disengages from the extrusion rod 253, the extrusion rod 253 is reset under the action of the fourth spring 254, the trigger switch 255 is reset, and the metering pump 242 stops working.
