Description

Technical Field

[0001] This application relates to the field of environmental sanitation cleaning equipment, and particularly to a rapid road surface garbage sweeper. Background Art

[0002] Road cleanliness is an essential operation in municipal engineering. With the continuous improvement of the degree of automation, road surface cleaning has gradually started to use various automated equipment for operation.

[0003] Currently, the garbage cleaning function of heavy road surface garbage sweepers consumes a large amount of power energy, which is not ideal. Most light road surface garbage sweepers have relatively single functions and do not have the functions of cleaning garbage, collecting garbage and branches. Generally, general road surface garbage is collected into the garbage bin in the carriage, but it is difficult to suck branches into the carriage. And during the process of dumping garbage, sanitation workers need to disassemble the garbage bin and move it to the garbage station to achieve garbage cleaning.

[0004] Regarding the above related technologies, the inventor believes that there are defects such as low efficiency of manual garbage cleaning and difficulty in cleaning road surface branches and leaves. Summary of the Invention

[0005] In order to improve the efficiency of garbage cleaning and collect garbage such as road surface branches and leaves, this application provides a rapid road surface garbage sweeper.

[0006] A rapid road surface garbage sweeper provided by this application adopts the following technical solutions:

[0007] A rapid road surface garbage sweeper includes a sweeper body, the sweeper body includes a vehicle head and a carriage. A garbage cleaning device is arranged at the front end of the vehicle head, a garbage collection device is arranged at the bottom of the carriage, and a garbage conveying device is arranged on the carriage;

[0008] The garbage conveying device includes a conveying air duct connected to the carriage. One end of the conveying air duct is connected to the garbage collection device, and the other end is connected to the carriage. The conveying air duct is used for transmitting the garbage at the bottom of the carriage into the carriage;

[0009] A driving source for driving the garbage to move is arranged on the conveying air duct;

[0010] A garbage outlet is arranged on the carriage, and a door panel is movably connected to the carriage. The door panel is used for blocking the garbage outlet.

[0011] Preferably, the driving source is set as a conveying fan. The air inlet of the conveying fan is communicated with the conveying air duct, and the orientation of the air inlet is the same as the garbage traveling direction;

[0012] An auxiliary conveying component is arranged in the conveying air duct. The auxiliary conveying component includes two groups of parallel circulating chains. The circulating chains are arranged along the length direction of the conveying air duct. A plurality of conveying rods are horizontally arranged between the two circulating chains. A raking member is fixedly connected to the conveying rod. The raking member is used to drive the garbage to move in the conveying air duct.

[0013] By adopting the above technical solution, when the garbage truck is running, the garbage cleaning device cleans the road surface garbage, so that the garbage is concentrated within the width range where the cleaning vehicle body travels. Then, the garbage collection device and the garbage conveying device are used to collect and transport the garbage. The garbage collected by the garbage collection device will enter the conveying air duct. The conveying air duct transports the garbage into the carriage, so that all the garbage can enter the carriage. When it is necessary to clean the garbage, the door panel can be opened to make the garbage directly fall from the garbage outlet into the garbage station.

[0014] During the process of cleaning the road surface, the sanitation workers do not need to manually carry and transfer the garbage, so the efficiency of garbage cleaning is greatly improved. The conveying fan can introduce a driving air flow into the conveying air duct, so that the air flow drives the garbage to move in the conveying air duct, which can smoothly transfer the garbage from the bottom of the carriage to the carriage by the conveying air duct, realizing the automatic transfer of the garbage. Since the second horizontal section is the end of the conveying air duct for entering garbage, it can act on the garbage to make the garbage move upward and smoothly enter the carriage.

[0015] During the rotation of the two groups of circulating chains, a plurality of conveying rods will be driven to move. The conveying rods can drive the raking members to move in a cycle. The raking members can hook the garbage, so that the garbage is transported upward along the conveying air duct and enters the carriage, and can also transport the branches on the road surface into the carriage. The auxiliary conveying component can cooperate with the air flow to smoothly drive the long-strip garbage such as branches to move upward, realizing the collection of garbage such as branches.

[0016] Preferably, the two circulating chains extend into the garbage collection device.

[0017] By adopting the above technical solution, the circulating chains can extend into the garbage collection device. Therefore, during the garbage collection process, the collection of garbage such as branches can be realized, the road surface cleaning effect is better, and the branches are prevented from blocking the conveying air duct, ensuring the smoothness of the conveying air duct.

[0018] Preferably, a material leakage hole is opened at the bottom of the conveying air duct, a heavy garbage bin is arranged at the tail of the carriage, and a material receiving through groove is opened on the heavy garbage bin. The material receiving through groove corresponds to the position of the material leakage hole.

[0019] By adopting the above technical solution, after the branches and leaves and stones on the road surface enter the inside of the conveying air duct, the branches and leaves enter the inside of the carriage driven by the wind force and the circulating chain, and the small stones fall from the material leakage holes under the action of gravity, and the heavy garbage bin collects the stones. Therefore, the classification of light and heavy garbage can be realized, and the efficiency of garbage collection and separation can be improved.

[0020] Preferably, the carriage bottom plate is set as a movable plate, the movable plate is hinged to the carriage, and the hinged position is on one side close to the garbage outlet;

[0021] Both sides of the movable plate are provided with opening and closing connecting rods, one end of the opening and closing connecting rod is hinged to the movable plate, and the other end is hinged to the door panel.

[0022] By adopting the above technical solution, when the garbage needs to be cleaned, the movable plate is tilted upwards, the movable plate drives the garbage to move, and the garbage falls from the garbage outlet position under the action of gravity and guidance, realizing the transfer of the garbage.

[0023] And when the movable plate moves, the movable plate is linked with the door panel through the opening and closing connecting rod. Therefore, when the movable plate tilts upwards, the door panel automatically opens and the garbage falls. After the garbage is cleaned, the movable plate resets, and at the same time the door panel closes to ensure the normally closed state of the garbage outlet. The door panel can be automatically opened when cleaning the garbage, with a high degree of automation and higher cleaning efficiency.

[0024] Preferably, a guiding component is arranged at the bottom of the carriage. The guiding component includes a sliding plate arranged at the bottom of the carriage. The sliding plate is in sliding fit with the movable plate. When the sliding plate is in the slid-out state, the sliding plate is located below the garbage outlet.

[0025] By adopting the above technical solution, generally, the space occupied by the tires and the body of the road sweeper is relatively large, and the garbage falling from the garbage outlet may fall on the tires or the bottom of the road sweeper body. However, the sliding plate can extend towards the outside of the carriage and is below the garbage outlet, which can play a guiding role for the garbage when dumping the garbage, making the cleaning work more convenient.

[0026] Preferably, a lifting cylinder for driving the movable plate to rotate is arranged at the bottom of the carriage;

[0027] The limiting frame is fixedly connected to the bottom of the movable plate, and a linkage rod group for driving the sliding plate to move is arranged at the bottom of the carriage. The lifting cylinder is linked with the linkage rod group.

[0028] By adopting the above technical solution, when the lifting cylinder is started, the lifting cylinder can push the movable plate to make the movable plate tilt upwards, thereby realizing the automatic cleaning of the garbage and improving the cleaning efficiency.

[0029] When the movable plate tilts upward, it will drive the sliding plate to rotate. Therefore, the sliding plate can tilt downward to guide the garbage. Start the lifting cylinder, and the lifting cylinder will drive the linkage rod group, causing the linkage rod group to act on the sliding plate to make the sliding plate move. When the sliding plate fully extends, it will be limited by the limit plate. The lifting cylinder continues to operate. At this time, the lifting cylinder acts on the movable plate to make the movable plate flip. Therefore, when cleaning the garbage, the sliding plate slides out first, the movable plate then tilts up, and at the same time the door panel opens, so that the garbage can be dumped smoothly. One lifting cylinder can achieve three-linkage, improving the efficiency of the cleaning work and reducing the production cost.

[0030] Preferably, the garbage cleaning device includes a fixed disk brush assembly and an opening and closing disk brush assembly, and the fixed disk brush assembly and the opening and closing disk brush assembly are connected to the vehicle head through a connecting assembly;

[0031] The connecting assembly includes a lifting frame group and an opening and closing frame group. The fixed disk brush assembly is connected to the lifting frame group, and the opening and closing disk brush assembly is connected to the lifting frame group through the opening and closing frame group;

[0032] The lifting frame group includes a lifting rod that slides in the vertical direction;

[0033] The opening and closing frame group includes an opening and closing rod hinged to the lifting rod;

[0034] A cleaning drive assembly is provided on the vehicle head, and the cleaning drive assembly includes a lifting drive part and an opening and closing drive part.

[0035] By adopting the above technical solutions, the fixed disk brush assembly and the opening and closing disk brush assembly can clean the garbage on the road surface, and the fixed disk brush and the opening and closing disk brush can move up and down driven by the lifting cylinder. When the road surface is not being cleaned, the entire garbage cleaning device can be lifted.

[0036] The opening and closing disk brush assembly can displace relative to the fixed disk brush assembly, that is, the opening and closing rod can be unfolded or retracted. The cleaning range is larger when the opening and closing disk brush assembly is in the unfolded state. When the garbage is not being cleaned, the opening and closing disk brush assembly can be retracted without affecting the progress of the vehicle.

[0037] Preferably, the opening and closing frame group further includes a swing rod hinged to the opening and closing rod. A floating spring is connected between the swing rod and the opening and closing rod, and the opening and closing disk brush assembly is connected to the end of the swing rod far away from the opening and closing rod;

[0038] The opening and closing drive part includes a driven connecting rod hinged to the opening and closing rod and a connecting plate connected to the driven connecting rod. The driven connecting rod is hinged to the connecting plate, and the connecting plate is slidably arranged on the lifting rod and is linked with the lifting rod;

[0039] By adopting the above technical solution, when the sweeper body is cleaning the curb, the opening and closing disc brush assembly can clean the curb, but because it is close to the curb, the opening and closing disc brush assembly may scratch the curb or even break. Under the action of the floating spring, when the opening and closing disc brush assembly collides with the curb, the floating spring contracts to avoid damage to the opening and closing disc brush assembly. In addition, the curb can be fully cleaned, and the cleaning effect is better.

[0040] When the lifting rod moves up and down, the connecting plate can be linked to move, so the opening and closing rod can swing. This linkage method does not require an additional drive source, and only one cylinder is used to achieve the lifting and lowering of the two disc brush assemblies, as well as the unfolding and storage of the opening and closing disc brush assemblies, saving resources and being more efficient.

[0041] Preferably, the garbage collection device comprises a collection bracket connected to the frame of the cleaning vehicle body, the collection bracket is provided with a collection air duct and a collection fan, the collection air duct is connected to the conveying air duct, and the collection fan is used to drive the garbage to move in the collection air duct;

[0042] The collecting bracket can move in a vertical direction, and the lifting and lowering of the collecting bracket is linked with the lifting and lowering of the lifting rod.

[0043] Preferably, a transition air duct is provided between the collecting air duct and the conveying air duct, one end of the collecting air duct is passed through the transition air duct, and one end of the transition air duct away from the collecting air duct is passed through the conveying air duct;

[0044] The transition air duct includes two interconnected folding plates, which are enclosed with each other to form a channel-like structure. The two side walls of the two folding plates are overlapped and connected to each other, and the folding plates are provided with notches at the bending positions near both ends.

[0045] By adopting the above technical solution, when the lifting rod moves up and down, the collection bracket can be driven to move up and down, so the lifting rod can drive the entire garbage collection device to move up and down, and the garbage cleaning device and the garbage collection device are in contact with the road surface synchronously during the garbage cleaning process. And only one driving source is used for driving, which can save costs and reduce energy consumption.

[0046] Since the garbage collection device is coordinated with the conveying air duct, the collection air duct will press against the top wall or bottom wall of the transition air duct during the up and down movement of the garbage collection device. Since slots are provided on both sides of the folding plate, the folding plate will bend and deform when subjected to force. Even if the collection air duct moves up and down, the garbage can be smoothly transferred into the conveying air duct to achieve garbage transfer.

[0047] Preferably, a tipping frame is hinged to the main body of the sweeper. The hinge point of the tipping frame is located at the rear of the vehicle. The carriage is fixedly connected to the tipping frame, and the garbage outlet is arranged at the rear of the carriage.

[0048] By adopting the above technical solution, the entire carriage can be tipped under the action of the tipping frame. The garbage entering the carriage is dispersed to the position of the garbage outlet through the garbage diversion plate. When the tipping frame rotates, the garbage can fall from the garbage outlet, realizing the transfer and cleaning of the garbage, and the garbage cleaning efficiency is higher.

[0049] In summary, the present application includes at least one of the following beneficial technical effects:

[0050] 1. The conveying air duct can play a role in transporting the garbage at the bottom of the garbage truck, so that the garbage is transferred to the carriage. When the garbage needs to be cleaned, the door panel can be automatically opened, so that the garbage directly falls from the garbage outlet into the garbage station. During the process of sweeping the road surface, the sanitation workers do not need to manually carry and transfer the garbage, and the transfer and transmission of the garbage can be automated, so the garbage cleaning efficiency is greatly improved;

[0051] 2. The circulating chain in the conveying air duct can drive the conveying rod and the raking member to move circularly inside the air duct, and can collect light garbage, especially branches and leaves, into the carriage, and the cleaning effect is more remarkable; and the circulating chain can extend to the garbage collection device, so that during the garbage collection process, garbage such as branches can be collected, the road surface cleaning effect is better, and the branches are prevented from blocking the conveying air duct to ensure the smoothness of the conveying air duct;

[0052] 3. After the branches and leaves and stones on the road surface enter the conveying air duct, the branches and leaves enter the carriage under the action of the wind force and the circulating chain, and the small stones fall from the leakage holes under the action of gravity, and the stones can be collected with a garbage box, so the classification of heavy and light garbage can be realized;

[0053] 4. The collection fan in the garbage collection device and the conveying fan on the conveying air duct can act on the garbage together. With the assistance of the double air flow, the garbage can enter the carriage more smoothly and quickly, and by adopting the double air flow, the garbage can be transmitted with smaller power of the two fans, saving energy consumption.

[0054] 5. The movable plate is linked with the door panel through the opening and closing connecting rod. Therefore, when the movable plate tilts up, the door panel automatically opens and the garbage falls. After the garbage is cleaned, the movable plate resets and the door panel closes at the same time. The door panel can be automatically opened when cleaning the garbage, with high automation and higher cleaning efficiency;

[0055] 6. The lifting cylinder can not only drive the movable plate to rotate, but also when acting on the linkage rod group, the sliding plate will extend first. When the sliding plate is fully extended, it will be limited by the limit plate, and the lifting cylinder will continue to operate. At this time, the lifting cylinder acts on the movable plate to turn the movable plate over, thereby improving the efficiency of the cleaning work. In addition, the use of one cylinder for driving reduces energy consumption and is more energy-saving and environmentally friendly.

[0056] 7. The opening and closing disc brush assembly can be displaced relative to the fixed disc brush assembly, that is, the opening and closing rod can be unfolded or retracted, and the cleaning range of the opening and closing disc brush assembly is larger when it is unfolded;

[0057] 8. When cleaning the curb, when the second electric disc brush contacts the curb, the floating spring contracts to avoid damage to the second electric disc brush. The curb can also be fully cleaned, resulting in better cleaning effect.

[0058] 9. The lifting cylinder can be used to lift the fixed disc brush assembly and the opening and closing disc brush assembly, as well as to unfold and store the opening and closing disc brush assembly, saving resources and increasing efficiency;

[0059] 10. The lifting cylinder drives the lifting rod to move up and down, and can also link the lifting of the entire garbage collection device. One lifting cylinder can achieve three functions, reducing the drive source setting of the entire garbage truck, saving costs and improving work efficiency;

[0060] 11. When the garbage collection device moves up and down, the collection air duct will press against the top wall or bottom wall of the transition air duct. Since slots are provided on both sides of the folding plate, the folding plate will bend and deform when subjected to force. Even if the collection air duct moves up and down, the garbage can be smoothly transferred into the conveying air duct to achieve the transfer of garbage.

[0061] 12. The diversion channel can guide the airflow in the car into the main diversion pipe, and then the airflow enters the secondary diversion pipe, and then enters the collection air duct through the diversion short pipe. The airflow in the car can be used to drive the movement of garbage, making the transportation of garbage smoother, and realizing the secondary utilization of resources and saving energy.

[0125] The following will Figures 1 - 31 make a further detailed description of this application in conjunction with the attached

[0126] This application embodiment discloses a rapid road surface garbage cleaning vehicle.

[0127] Embodiment 1:

[0128] Referring to Figure 1 , the rapid road surface garbage cleaning vehicle includes a cleaning vehicle body 1. The cleaning vehicle body 1 includes a vehicle head 11 and a carriage 12. A garbage cleaning device 2 is arranged below the vehicle head 11, a garbage collection device 3 is arranged below the carriage 12, and a garbage conveying device 5 is arranged at the tail of the carriage 12. A garbage outlet 121 is opened on the side wall of the carriage 12, and a door panel 122 is provided at the position of the garbage outlet 121.

The relatively light garbage can enter the carriage 12 through the garbage conveying device 5. When it is necessary to process the garbage in the carriage 12, the door panel 122 can be opened, and the garbage is discharged from the garbage outlet 121, which conveniently realizes the dumping of the garbage.

[0130] Referring to Figure 2 , the garbage cleaning device 2 includes a fixed disk brush assembly 22 and a movable disk brush assembly 23. The fixed disk brush assembly 22 and the movable disk brush assembly 23 are connected to the bottom of the vehicle head 11 through a connecting assembly 21, and the connecting assembly 21 realizes lifting and opening / closing through a cleaning driving assembly 24.

[0131] Referring to Figure 3 , the fixed disk brush assembly 22 includes two first electric disk brushes 221, and the movable disk brush assembly 23 includes two second electric disk brushes 231. Both the first electric disk brush 221 and the second electric disk brush 231 include a fixed disk, the fixed disk can be connected to a specific supporting component, a cleaning motor is fixedly connected to the fixed disk, a cleaning disk brush is rotatably connected to the lower end of the fixed disk, and the output shaft of the cleaning motor is fixedly connected to the central position of the cleaning disk brush.

[0132] Referring to Figure 3 , the connecting assembly 21 includes a lifting frame group 211 and an opening / closing frame group 212. The fixed disk brush assembly 22 is arranged on the lifting frame group 211, and the movable disk brush assembly 23 is connected to the lifting frame group 211 through the opening / closing frame group 212. The lifting frame group 211 includes a lifting rod 2111, and the lifting rod 2111 includes an integrally formed long rod and two short rods, and the two short rods are located at both ends of the long rod. The two first electric disk brushes 221 correspond to the positions of the two short rods one by one, and the fixed disk in the first electric disk brush 221 is fixedly connected to the short rod.

[0133] Referring to Figure 3 , there are two sets of opening / closing frame groups 212, and the two sets of opening / closing frame groups 212 are symmetrically arranged about the center line of the long rod in the length direction. The opening / closing frame group 212 includes an opening / closing rod 2121 rotatably connected to the short rod. By rotating the opening / closing rod 2121, the angle between the opening / closing rod 2121 and the lifting rod 2111 is changed, so as to realize the unfolding and storage of the movable disk brush assembly 23.

[0134] Referring to Figure 3, in order to reduce the friction and collision between the opening and closing disk brush assembly 23 and the road edge when it is opened, a swing rod 2122 is hinged to the front end of the opening and closing rod 2121. A certain angle is formed between the swing rod 2122 and the opening and closing rod 2121, and a floating spring 2123 is connected between the swing rod 2122 and the opening and closing rod 2121. One end of the floating spring 2123 is fixedly connected to the side wall of the swing rod 2122, and the other end is fixedly connected to the side wall of the opening and closing rod 2121.

[0135] Refer to Figure 3 , the second electric disk brush 231 is connected to the free end of the swing rod 2122, that is, the fixed disk in the second electric disk brush 231 is fixedly connected to the swing rod 2122.

[0136] When the opening and closing disk brush assembly 23 is in the unfolded state, the distance between the two second electric disk brushes 231 is greater than the width of the vehicle head 11, at least exceeding 0.5 meters, and the cleaning range is relatively large. And when cleaning the edge of the road, the second electric disk brush 231 can be close to the road edge. Under the action of the floating spring 2123, even if the distance between the vehicle body and the road edge is relatively close, the second electric disk brush 231 will swing towards the vehicle body range under the action of the resisting force, without causing damage to the second electric disk brush 231, and the cleaning is cleaner.

[0137] Refer to Figure 3 , in order to reduce the drive source of the entire road sweeper body 1 and reduce costs. The lifting of the lifting frame group 211 is linked with the opening and closing of the opening and closing frame group 212. The specific structure is as follows: The cleaning drive assembly 24 includes a lifting drive part 241 and an opening and closing drive part 242.

[0138] Refer to Figure 4 , the lifting drive part 241 includes a vertically arranged lifting cylinder 2411. The cylinder body of the lifting cylinder 2411 is fixedly connected to the vehicle head 11, and the piston rod of the lifting cylinder 2411 faces downward and is fixedly connected to the middle position of the long rod. When the lifting cylinder 2411 is started, the lifting cylinder 2411 can drive the lifting rod 2111 to move up and down to achieve lifting. In order to ensure the stability of the lifting rod 2111 during the lifting process, guiding rods 2112 can be arranged at both ends of the long rod. The guiding rods 2112 are telescopic rods. One end of the telescopic rod is fixedly connected to the vehicle head 11, and the other end is connected to the long rod to ensure smoothness.

[0139] Refer to Figure 4, the opening and closing drive part 242 includes a fixed rod 2421 fixedly connected to the vehicle head 11 and a driven connecting rod 2424 hinged to the opening and closing rod 2121. There are two driven connecting rods 2424 corresponding to the opening and closing rod 2121. A connecting plate 2423 is commonly connected to the opposite ends of the two driven connecting rods 2424. Both driven connecting rods 2424 are hinged to the connecting plate 2423. A driving connecting rod 2422 is arranged between the connecting plate 2423 and the fixed rod 2421. One end of the driving connecting rod 2422 is hinged to the fixed rod 2421, and the other end is hinged to the connecting plate 2423. The fixed rod 2421 extends below the connecting assembly 21.

[0140] Referring to Figure 4 , when the connecting assembly 21 descends driven by the lifting cylinder 2411, the distance between the connecting plate 2423 and the lower end face of the fixed rod 2421 becomes shorter in the vertical direction. The front end of the driving connecting rod 2422 swings downward, causing the connecting plate 2423 to swing in the vehicle's forward direction, enabling the two driven connecting rods 2424 to rotate. The angle between the two driven connecting rods 2424 becomes larger to push against the opening and closing rod 2121, causing the opening and closing rod 2121 to open. On the contrary, when the connecting assembly 21 ascends, the two opening and closing rods 2121 rotate and close under the linkage of the driven connecting rods 2424.

[0141] Referring to Figure 5 and Figure 6 , the garbage collection device 3 includes a collection bracket 33. A collection air duct 31 is connected to the collection bracket 33. A cleaning carpet 311 is arranged in the collection air duct 31. A plurality of garbage inlets 3111 are arranged on the cleaning carpet 311. The cleaning carpet 311 is located at the bottom of the collection air duct 31 and is in contact with the ground during the cleaning process of the cleaning vehicle body 1, and can shovel the garbage on the road surface, enabling the garbage to enter the collection air duct 31 from the garbage inlets 3111.

[0142] Referring to Figure 6 , an air duct door plate 312 is covered on the cleaning carpet 311. The air duct door plate 312, the collection air duct 31, and the cleaning carpet 311 form a channel for the garbage to move. A collection fan 32 is fixedly connected to the collection bracket 33. The collection fan 32 is arranged at one end of the collection air duct 31 facing the vehicle head 11, and the air outlet of the collection fan 32 faces the inside of the collection air duct 31. During the travel of the cleaning vehicle body 1, the collection fan 32 can drive the air flow to flow towards the tail of the carriage 12, realizing the collection of the road surface garbage.

[0143] On the road surface, there are not only light garbage (such as branches, dust, and garbage bags), but also heavy garbage (such as bricks, bumps, and stones). Heavy garbage will not easily float under the action of air flow. When the vehicle is driving, it will jolt. Therefore, under the action of inertia and gravity, the heavy garbage continuously jumps towards the tail of the carriage 12, while the light garbage will float in the collection air duct 31 under the action of air flow and also quickly move towards the tail of the carriage 12.

[0144] Referring to Figure 7 , in order to separate heavy garbage and light garbage, a separation air duct 34 is provided at the tail of the collection air duct 31, and the separation air duct 34 is connected to the collection air duct 31. The separation air duct 34 includes a light garbage channel 341 and a heavy garbage channel 342 that are connected to each other. The light garbage channel 341 is arranged above the heavy garbage channel 342. The garbage entering the tail of the collection air duct 31 will be automatically divided into heavy garbage and light garbage under the action of air flow. The heavy garbage enters the heavy garbage channel 342, and the light garbage enters the light garbage channel 341 to achieve garbage sorting.

[0145] Referring to Figure 7 , a heavy garbage bin 35 is detachably connected to the tail of the carriage 12. A heavy garbage inlet is provided on one side of the heavy garbage bin 35, and the heavy garbage channel 342 passes through the heavy garbage inlet. The heavy garbage can continuously roll into the heavy garbage bin 35 to collect the heavy garbage, and the detachably arranged heavy garbage bin 35 can facilitate the workers to clean the heavy garbage. The heavy garbage bin 35 can be specifically connected to the collection bracket 33.

[0146] Referring to Figure 8 , when the garbage truck is not performing cleaning work, in order to reduce the frictional loss caused by the collection air duct 31 and the heavy garbage bin 35 fitting the road surface, the entire collection bracket 33 is set as a liftable structure. At the same time, in order to reduce the energy consumption of the entire cleaning vehicle body 1, reduce the setting of drive sources, and reduce costs, the liftable structure of the collection bracket 33 is linked with the cleaning drive device. Specifically, a lift linkage device 4 is provided at the bottom of the carriage 12, and the lift linkage device 4 includes a main drive part 41 and a linkage part 42.

[0147] Referring to Figure 8 and Figure 9 , the main drive part 41 includes a rack 411 fixedly connected to the lift rod 2111 and a gear 412 meshing with the rack 411. The gear 412 is rotatably connected to the bottom of the vehicle head 11. In order to ensure the stability of the entire lift linkage device 4, two symmetrically arranged racks 411 and gears 412 are provided. A connecting shaft 413 is coaxially fixedly connected between the two gears 412.

[0148] Referring to Figure 8, the linkage part 42 includes a winding and unwinding sprocket 421 coaxially and fixedly connected to the connecting shaft 413. A traction chain 422 is meshed outside the winding and unwinding sprocket 421. One end of the traction chain 422 is fixedly connected to the outer circumferential surface of the winding and unwinding sprocket 421, and the other end is fixedly connected to the collection bracket 33. The traction chain 422 is specifically connected to the lower half of the winding and unwinding sprocket 421. In order to make the force for pulling the collection bracket 33 be the traction force in the vertical direction, a steering guide wheel 423 is rotatably connected to the bottom of the carriage 12. The steering guide wheel 423 can be set as a sprocket, and the traction chain 422 is meshed with the steering guide wheel 423.

[0149] Refer to Figure 8 , when the cleaning vehicle body 1 does not perform cleaning work, the lifting cylinder 2411 drives the lifting rod 2111 to move upward. The lifting rod 2111 drives the rack 411 to move. During the upward movement of the rack 411, it will mesh with the gear 412, and the gear 412 rotates counterclockwise. Since the connection point of the traction chain 422 is located in the lower half of the winding and unwinding sprocket 421, the traction chain 422 can be wound around the outside of the winding and unwinding sprocket 421. The traction chain 422 can pull the collection bracket 33, so that the collection bracket 33 moves upward and is separated from the ground, and the friction loss between the collection air duct 31 and the ground can be reduced.

[0150] In the specific production process, the specific number of the traction chains 422 can be selected and set according to the size and weight of the collection bracket 33 and the entire collection air duct 31. If the weight of the collection air duct 31 is relatively heavy, 3 - 4 traction chains 422 can be set to ensure the stability during the traction process. Of course, the chain is the optimal solution in this embodiment, and the chain can be replaced with a steel wire rope, a hemp rope or other structures as long as it can play a certain traction role.

[0151] Refer to Figure 10 , the garbage conveying device 5 includes a conveying air duct 51 arranged at the tail of the carriage 12. The conveying air duct 51 connects the collection air duct 31 with the carriage 12. The light garbage in the collection air duct 31 can enter the carriage 12 through the conveying channel.

[0152] Refer to Figure 10 , there is a certain gap between the conveying air duct 51 and the tail of the carriage 12. A dust suppression device 6 is arranged at the gap. The dust suppression device 6 includes a water tank 61 fixedly connected to the carriage 12. Spraying water is stored in the water tank 61. A spray pipe 62 is communicated with the water tank 61. The spray pipe 62 extends to the bottom of the conveying air duct 51. A water pump is arranged on the water tank 61. The water pump is communicated with the spray pipe 62. The spraying water is pumped into the spray pipe 62 through the water pump. Nozzles are arranged on the spray pipe 62. During the operation of the cleaning vehicle body 1, the dust suppression device 6 can sprinkle water synchronously to reduce the dust during the road operation.

[0153] Refer to Figure 11, the conveying air duct 51 includes a first horizontal section 511, a second horizontal section 512, and a vertical section 513 connecting the first horizontal section 511 and the second horizontal section 512. The first horizontal section 511 and the second horizontal section 512 are parallel to each other. The first horizontal section 511 and the second horizontal section 512 are connected to the vertical section 513 through a bending section 514.

[0154] Referring to Figure 7 and 10 , the first horizontal section 511 is fixedly connected to the carriage 12. The first horizontal section 511 passes through the tail of the carriage 12 and extends into the carriage 12. The second horizontal section 512 extends to the bottom of the carriage 12. The light garbage duct 341 is arranged in the second horizontal section 512. The garbage in the light garbage duct 341 can enter the conveying air duct 51 under the action of the air flow.

[0155] Referring to Figure 11 , in order to ensure the smooth transmission of the garbage, an installation platform 516 and an installation opening are arranged on the upper end surface of the second horizontal section 512. A conveying fan 52 is fixedly connected to the installation platform 516. The air outlet of the conveying fan 52 extends into the installation opening. Therefore, the conveying fan 52 can introduce air flow into the conveying air duct 51. When the light garbage enters the second horizontal section 512, under the action of the air flow of the conveying fan 52, the light garbage can smoothly move upward in the vertical section 513 and be transferred into the carriage 12.

[0156] Referring to Figure 11 , during the process of garbage conveying, in order to retain the maximum wind force as much as possible, the bending section 514 is set to be in an arc transition shape, so that the inner wall of the conveying air duct 51 is integrally streamlined, which can reduce the weakening effect on the air flow size, and the garbage conveying effect is significantly increased.

[0157] Referring to Figure 11 , since the collection bracket 33 will drive the collection air duct 31 to move up and down, in order to prevent the conveying air duct 51 from affecting the up and down movement of the collection air duct 31, a transition air duct 55 is arranged at one end of the garbage inlet 3111 of the conveying air duct 51. One end of the transition air duct 55 is arranged in the conveying air duct 51, and the other end extends to the outside of the conveying air duct 51, and the light garbage duct 341 is arranged in the transition air duct 55.

[0158] Referring to Figure 12 and Figure 13 , the transition air duct 55 includes two connected folding plates 551. The cross section of the folding plate 551 is U-shaped. The two side walls where the folding plates 551 are bent overlap each other and are connected by two groups of connecting pieces, so that the two folding plates 551 enclose a tubular channel.

[0159] Referring to Figure 12 and Figure 13, the connecting member includes two fixing bars 552, one of the fixing bars 552 is arranged on the outer side of the tubular channel, and the other fixing bar 552 is arranged on the inner side of the tubular channel. The two fixing bars 552 clamp the same side edge of the two folding plates 551, and the folding plates 551 and the two fixing bars 552 are fixed by rivets.

[0160] Refer to Figure 12 and Figure 13 , the folding plates 551 are made of stainless steel plates. Notches 553 are provided on both side walls of the folding plates 551 near both ends. Therefore, the two ends of the transition air duct 55 will deform when subjected to pressure. When the collection bracket 33 drives the collection air duct 31 to move up and down, the collection air duct 31 will drive the light garbage channel 341 to abut against the transition air duct 55, and the transition air duct 55 will deform, so it will not affect the smooth collection of garbage.

[0161] Refer to Figure 10 , one side edge of the door panel 122 is hinged to the carriage 12 through a hinge. In this embodiment, the upper side edge of the door panel 122 is preferably the hinged side edge, that is, the door panel 122 can be turned upwards when cleaning the garbage. During the driving process of the cleaning vehicle body 1, the door panel 122 blocks the garbage.

[0162] Refer to Figure 14 , the bottom plate of the carriage 12 is a movable plate 123. The movable plate 123 is hinged to one side of the carriage 12 close to the garbage outlet 121. A lifting cylinder 13 is arranged at the bottom of the carriage 12. The lifting cylinder 13 can be hinged to the frame of the cleaning vehicle body 1. The piston rod of the lifting cylinder 13 faces upwards and is hinged to the bottom of the movable plate 123. In order to reduce the stroke required when the cylinder operates, the hinge point between the cylinder and the movable bottom plate is close to the garbage outlet 121.

[0163] Refer to Figure 14 , at the same time, the movable plate 123 is linked with the door panel 122. An opening and closing connecting rod 124 is connected between the movable plate 123 and the door panel 122. One end of the opening and closing connecting rod 124 is hinged to the side wall of the movable plate 123, and the other end is hinged to the door panel 122. There are two opening and closing connecting rods 124, and the two opening and closing connecting rods 124 are symmetrically arranged on both sides of the movable plate 123.

[0164] Refer to Figure 14 , when it is necessary to clean the garbage, the lifting cylinder 13 is started. The lifting cylinder 13 pushes the movable plate 123, and the movable plate 123 turns upwards and tilts. At the same time, under the drive of the opening and closing connecting rod 124, the door panel 122 can also turn outwards and open. The garbage slides outwards of the carriage 12 under the guiding action of the movable plate 123, and the transfer of the garbage can be realized without manual cleaning.

[0165] Refer to Figure 14In order to prevent garbage from falling from the gap between the movable plate 123 and the inner wall of the carriage 12, a baffle 1231 is fixedly connected to one side of the movable plate 123 away from the hinge point. The baffle 1231 and the movable plate 123 are perpendicular to each other, which can limit the garbage and prevent it from falling from the gap between the movable plate 123 and the inner wall of the carriage 12 when the movable plate 123 tilts upward. The baffle 1231 can be set at the three side positions of the movable plate 123 except the hinged side to prevent garbage from falling from the gap.

[0166] Reference Figure 14 and Figure 15 In order to ensure the air pressure balance in the compartment 12, an air vent 125 is opened on the top wall of the compartment 12, and a filter 126 is installed at the position of the air vent 125. The filter 126 can intercept the air vent 125 and ensure the smooth flow of air.

[0167] Reference Figure 15 A rain shield 127 is fixedly connected to the top of the carriage 12 , and the rain shield 127 is arranged above the air vent 125 , so that the rain shield 127 can play a certain protective role on the air vent 125 to prevent rainwater from entering the carriage 12 .

[0168] Reference Figure 15 In order to facilitate the inspection inside the carriage 12 and the assembly and inspection of the lifting cylinder 13, an inspection port is opened on the side wall of the carriage 12, and an inspection door 128 is provided at the inspection port. The inspection door 128 is set as a double door. When inspection is not required, the inspection door 128 can be fixed and limited by a latch or a buckle structure.

[0169] In order to reduce costs, the sweeper body 1 can be a small electric truck, which can be a three-wheel structure or a four-wheel structure.

[0170] The implementation principle of Example 1 is as follows: when cleaning road garbage, the vehicle is traveling on the road, and under normal circumstances, the garbage cleaning device 2 and the garbage collecting device 3 are both in the lifting state. Start the lifting cylinder 2411, and the piston rod of the lifting cylinder 2411 moves downward, driving the lifting frame group 211 to move downward. At the same time, the distance between the connecting plate 2423 and the lower end surface of the fixed rod 2421 in the vertical direction becomes shorter, and the front end of the driving connecting rod 2422 swings downward, so that the connecting plate 2423 swings in the forward direction of the vehicle, which can make the two driven connecting rods 2424 rotate, and the angle between the two driven connecting rods 2424 becomes larger to move the opening and closing rod 2121, so that the opening and closing rod 2121 opens. The fixed disc brush assembly 22 and the opening and closing disc brush assembly 23 can be synchronously fitted with the ground, and the opening and closing disc brush assembly 23 can be unfolded, so that the road surface can be cleaned and the cleaning range can be guaranteed during the driving of the vehicle.

[0171] While the lifting frame group 211 moves downward, it drives the rack 411 to move. During the downward movement of the rack 411, it meshes with the gear 412, and the gear 412 rotates clockwise. The winding and unwinding sprocket 421 rotates to release the traction chain 422. Under the action of the gravity of the collection air duct 31, the collection air duct 31 moves downward, making the cleaning carpet 311 fit the ground.

[0172] Start the collection fan 32 and the conveying fan 52. The collection fan 32 can introduce air flow into the collection air duct 31. Under the dual action of the cleaning carpet 311 and the air flow, the garbage on the ground will enter the collection air duct 31. When the garbage moves to the tail of the collection air duct 31, the heavy garbage will be separated into the heavy garbage channel 342 and enter the heavy garbage bin 35. The light garbage will enter the light garbage channel 341 and enter the conveying air duct 51. The conveying fan 52 introduces air flow into the conveying air duct 51. Therefore, the garbage can enter the carriage 12 along the inner cavity of the conveying air duct 51.

[0173] After the garbage is collected inside the carriage 12, the garbage needs to be cleaned. When cleaning the garbage, start the lifting cylinder 13. The lifting cylinder 13 presses against the movable plate 123. While the movable plate 123 tilts upward, it drives the door plate 122 to open through the opening and closing connecting rod 124. The garbage slides downward under the action of gravity, realizing the automatic cleaning of the garbage, and there is no need for manual handling and transfer of the garbage.

[0174] Embodiment 2:

[0175] A fast road surface garbage cleaning vehicle, referring to Figure 16 , the difference from Embodiment 1 is that: an auxiliary conveying component 53 is arranged in the conveying air duct 51, mainly to make the garbage convey more smoothly in the conveying air duct 51.

[0176] Referring to Figure 17 and Figure 18 , at the end of the first horizontal section 511, two parallel first extension plates 537 extending outward are fixedly connected. The auxiliary conveying component 53 includes a driving rotating shaft 531 arranged between the two first extension plates 537. The driving rotating shaft 531 is rotatably connected to the two first extension plates 537. Specifically, a driving motor can be fixedly connected to one of the first extension plates 537, and the driving motor is linked with the driving rotating shaft 531 through a speed reducer. Active sprockets 532 are arranged at positions near both ends of the driving rotating shaft 531, and the active sprockets 532 are coaxially fixedly connected to the driving rotating shaft 531.

[0177] Referring to Figure 17 and Figure 19, at the end of the second horizontal section 512, two parallel second extension plates 538 extending outward are fixedly connected. The auxiliary conveying assembly 53 further includes a driven rotating shaft 533 disposed between the two second extension plates 538. The driven rotating shaft 533 is rotatably connected to the two second extension plates 538. At positions near both ends of the driven rotating shaft 533, driven sprockets 534 are provided. The driven sprockets 534 are linked to the driving gear 412 through a circulating chain 535, that is, two groups of parallel circulating chains 535 are provided.

[0178] Refer to Figure 18 and Figure 19 , between the two groups of circulating chains 535, a conveying rod 536 is fixedly connected. A plurality of parallel conveying rods 536 are provided. A plurality of raking members 5361 are fixedly connected to the conveying rod 536. When the driving sprocket 532 rotates, it can drive the circulating chain 535 to rotate in a cycle. During the rotation of the circulating chain 535, the conveying rod 536 will be driven to rotate in a cycle. Therefore, the raking members 5361 on the conveying rod 536 can move synchronously. When the raking member 5361 faces downward, the hook direction on the raking member 5361 points to the rear of the vehicle, so that the conveying rod 536 can act on the light garbage by using the raking member 5361 during the cyclic rotation.

[0179] Under the combined action of the air flow and the raking member 5361, the light garbage can smoothly enter the carriage 12, and during the cleaning process, it can prevent relatively large light garbage (such as branches and plastic bags) from accumulating in the conveying air duct 51, ensuring the smooth collection and transmission of the light garbage.

[0180] Refer to Figure 17 , in order to enable the circulating chain 535 to rotate smoothly in the conveying air duct 51, a plurality of steering sprockets 539 are rotatably provided at the bending part of the conveying air duct 51. At the same time, the bending section 514 of the conveying air duct 51 is set as a straight section. The included angle formed by the bending section 514 and the two horizontal sections and the vertical section 513 is 40° - 50°, and preferably 45° in this embodiment, which can reduce the number of steering sprockets 539 while ensuring the smooth cyclic rotation of the circulating chain 535.

[0181] Refer to Figure 17 , since the part of the second horizontal section 512 extending to the bottom of the carriage 12 is relatively long, a support wheel 540 is rotatably provided inside the second horizontal section 512. The support wheel 540 is disposed at the bottom of the circulating chain 535 and corresponds to the positions of the two groups of circulating chains 535. It can prevent the circulating chain 535 from fitting against the inner wall of the second horizontal section 512, enabling the conveying rod 536 to smoothly drive the short rod to transfer the garbage.

[0182] The implementation principle of Embodiment 2 is as follows: During the operation of the road sweeper body 1, the drive motor is started. The drive motor drives the active rotating shaft 531 and the active sprocket 532 to rotate. The active sprocket 532 can drive the circulating chain 535 to rotate in a cycle within the conveying air duct 51. During the rotation of the circulating chain 535, the conveying rod 536 can be driven to rotate. The conveying rod 536 drives the raking member 5361 to rotate in a cycle. During the cyclic rotation of the raking member 5361, light garbage can be hooked and transferred to the interior of the carriage 12, realizing the transfer of light garbage.

[0183] Embodiment 3:

[0184] A rapid road surface garbage sweeper, referring to Figure 20 , which is different from Embodiment 2 in that: Connecting rods 541 are rotatably connected to the ends of the two second extension plates 538 facing the vehicle head 11. The connecting rods 541 extend into the collection air duct 31. The driven rotating shaft 533 is rotatably arranged at the end of the connecting rod 541 facing the vehicle head 11. The circulating chain 535 and the conveying rod 536 pass through the transition air duct 55 and extend into the collection air duct 31.

[0185] The conveying rod 536 and the raking member 5361 can act on the garbage in the collection air duct 31, enabling the garbage to quickly enter the conveying air duct 51 and be transferred to the carriage 12, ensuring a fast and clean cleaning effect on the garbage.

[0186] Referring to Figure 21 , in order to prevent the connecting rod 541 from contacting the road surface through the garbage inlet 3111 during vehicle travel, a fixed support plate 542 is movably connected to the end of the connecting rod 541 facing the vehicle head 11. A roller 543 is rotatably connected to the lower end of the fixed support plate 542. In the state of vehicle jolting, the roller 543 can contact the ground, and the connecting rod 541 will not be damaged by friction with the ground.

[0187] Referring to Figure 21 , a vertical groove 5421 is formed on the fixed support plate 542. The fixed support plate 542 is connected to the connecting rod 541 by bolts. The rod part of the bolt passes through the vertical groove 5421 and is threadedly connected to the connecting rod 541. The head of the bolt abuts against the fixed support plate 542. This structure facilitates the adjustment of the position of the fixed support plate 542, and the position of the fixed support plate 542 can be adjusted according to the distance between the connecting rod 541 and the ground.

[0188] Referring to Figure 22 , since the auxiliary conveying assembly 53 extends into the collection air duct 31, during road surface cleaning, other heavy garbage such as stones may also enter the conveying air duct 51 under the drive of the auxiliary conveying assembly 53. Therefore, leakage holes 517 are provided at the bottom of the second horizontal section 512, and a plurality of leakage holes 517 are provided.

[0189] Reference Figure 22 Figure 22 , a material receiving through groove 351 is formed at the upper end of the heavy trash bin 35, and the material receiving through groove 351 is disposed directly below a plurality of material leakage holes 517. When the heavy trash enters the conveying air duct 51 driven by the auxiliary conveying assembly 53, the heavy trash will fall from the material leakage holes 517 under the action of gravity, and the heavy trash can fall into the heavy trash bin 35, which can prevent the heavy trash from staying in the second horizontal section 512, and further ensure garbage sorting, making the garbage cleaning work more time-saving and labor-saving while having higher efficiency.

[0190] Embodiment 4:

[0191] A rapid road surface garbage sweeper, reference Figure 23 and Figure 24 Figure 24 , the difference from all the foregoing embodiments is that: the opening and closing driving part 242 further includes a traction rod and a forsythia rod 2427. One end of the traction rod is hinged to the lifting rod 2111, and the other end is hinged to the end of the forsythia rod 2427. The forsythia rod 2427 includes an integrally formed short rod and a long rod. The forsythia rod 2427 is a bent rod, that is, a certain angle is formed between the short rod and the long rod. The long rod faces downward and inclines toward the side of the vehicle head 11. The traction rod is hinged to the end of the short rod, and the middle position of the short rod along the length direction is rotatably connected to the bottom of the fixed rod 2421. The bottom end of the long rod is hinged to the end of the driving link 2422.

[0192] The implementation principle of Embodiment 4 is: when the lifting rod 2111 moves up and down driven by the lifting cylinder 2411, the lifting rod 2111 can drive the traction rod to move synchronously. Since the forsythia rod 2427 is rotatably connected to the fixed rod 2421, the traction rod can drive the forsythia rod 2427 to rotate. When the forsythia rod 2427 rotates, it can synchronously drive the driving link 2422 to move, realizing the movement of the opening and closing frame group 212, and opening or storing the opening and closing disk brush assembly 23.

[0193] Since one end of the forsythia rod is short and the other end is long, under the action of the lever principle, the opening and closing angle between the opening and closing frame group and the lifting frame group is larger, so that the cleaning range of the sweeper body is larger and the cleaning effect is better.

[0194] Embodiment 5:

[0195] A rapid road surface garbage sweeper, reference Figure 25 Figure 25 , the difference from Embodiment 4 is that: the opening and closing driving part 242 includes an opening and closing cylinder 2425 fixedly connected to the long rod. The opening and closing cylinder 2425 is horizontally arranged, and the connecting plate 2423 is fixedly connected to the piston rod end of the opening and closing cylinder 2425.

[0196] Start the opening and closing cylinder 2425. The opening and closing cylinder 2425 drives the connecting plate 2423 to move, and the connecting angle plate drives the driven connecting rod 2424 to move. Therefore, the driven connecting rod 2424 will drive the second electric disk brush 231 to rotate, realizing the adjustment of the sweeping range.

[0197] Embodiment 6:

[0198] A rapid road surface garbage sweeper, referring to Figure 26 , which is different from all the foregoing embodiments in that: a guiding component 14 for guiding the garbage is provided at the bottom of the carriage 12.

[0199] Referring to Figure 27 , the guiding component 14 includes a sliding plate 141 slidably arranged at the bottom of the carriage 12. A limiting frame 142 is fixedly connected to the bottom of the carriage 12. The sliding plate 141 is slidably clamped and matched with the limiting frame 142. Both the limiting frame 142 and the sliding plate 141 are arranged on one side of the carriage 12 close to the garbage outlet 121.

[0200] Referring to Figure 27 , the limiting frame 142 includes two symmetrically arranged support plates. The cross-sectional shape of the support plate is L-shaped, that is, a chute for the sliding plate 141 to move is provided on the support plate, and the sliding plate 141 is slidably mounted on the two support plates. Step clamping grooves 1411 are opened on both sides of the sliding plate 141. Limiting plates 1421 are fixedly connected to one ends of the two support plates facing the outside of the carriage 12. The limiting plates 1421 are matched with the step clamping grooves 1411 in shape, and the limiting plates 1421 can play a role in limiting the sliding plate 141 to prevent the sliding plate 141 from separating from the limiting frame 142.

[0201] Before cleaning the garbage, the sliding plate 141 can be pulled to extend the sliding plate 141 towards the outside of the carriage 12, which can play a certain guiding role for the garbage. When cleaning the garbage, the garbage can be dumped to a position farther from the carriage 12.

[0202] Embodiment 7:

[0203] A rapid road surface garbage sweeper, referring to Figure 28 , which is different from Embodiment 6 in that: the limiting frame 142 is specifically fixed to the bottom of the movable plate 123. When the movable plate 123 turns up upwards, it can drive the limiting frame 142 and the sliding plate 141 to turn downwards, which can play a guiding role for the garbage and enable the garbage to quickly separate from the carriage 12.

[0204] Referring to Figure 28, and to achieve the automatic sliding of the sliding plate 141, the sliding plate 141 is linked with the lifting cylinder 13. A linkage rod group 15 is provided at the bottom of the carriage 12. The linkage rod group 15 is arranged at the middle position in the length direction of the movable plate 123 and corresponds to the position of the lifting cylinder 13. The linkage rod group 15 includes a main moving rod 151 and a secondary moving rod 152. One end of the main moving rod 151 is hinged to the bottom end of the movable plate 123, and the other end is hinged to one end of the secondary moving rod 152. The other end of the secondary moving rod 152 is hinged to the bottom end of the sliding plate 141. The piston rod end of the lifting cylinder 13 is hinged to the main moving rod 151.

[0205] The implementation principle of Embodiment 7 is as follows: Start the lifting cylinder 13. The lifting cylinder 13 first pushes the main moving rod 151. The main moving rod 151 drives the secondary moving rod 152 to displace. The secondary moving rod 152 extends outward from the carriage 12. Therefore, the secondary moving rod 152 drives the sliding plate 141 to move outward from the carriage 12, causing the sliding plate 141 to automatically slide to the outside of the carriage 12. Due to the limiting effect of the limiting plate 1421 on the sliding plate 141, after the sliding plate 141 slides a certain distance, the lifting cylinder 13 continues to push the main moving rod 151. At this time, the main moving rod 151 will act on the entire movable plate 123, causing the movable plate 123 to tilt upward, and at the same time, the door panel 122 opens, realizing the automatic cleaning and transfer of garbage.

[0206] Embodiment 8:

[0207] A rapid road surface garbage sweeper, referring to Figure 29 , different from all the foregoing embodiments in that: the top wall of the carriage 12 is a closed structure.

The flow guiding channel 161 is fixedly connected with a main flow guiding pipe 162, and the main flow guiding pipe 162 is communicated with the flow guiding channel 161.

[0209] Referring to Figure 29, the main diversion pipe 162 is communicated with one or two sub-diversion pipes 163. The sub-diversion pipes 163 are arranged on one side of the collecting air duct 31 in the length direction. A plurality of diversion short pipes 1631 are communicated with the sub-diversion pipes 163. The diversion short pipes 1631 are inclined towards the tail of the carriage 12, and the diversion short pipes 1631 pass through the side wall of the collecting air duct 31 and extend into the collecting air duct 31. If there are two sub-diversion pipes 163, the two diversion ducts are respectively arranged on both sides of the collecting air duct 31.

[0210] The implementation principle of Embodiment 8 is as follows: After the conveying air duct 51 transfers the garbage into the carriage 12, the air flow continues to flow into the diversion channel 161. The air flow sequentially passes through the main diversion pipe 162, the sub-diversion pipes 163 and the diversion short pipes 1631, and enters the collecting air duct 31 through the diversion short pipes 1631. The air flow can be reused, the air flow intensity in the collecting air duct 31 can be increased, the effect of cleaning garbage and sweeping the garbage can be strengthened, and the cleaning effect can be better.

The upper side edge of the door panel 122 is hinged to the garbage outlet 121, and the lower end can be fixed by a bolt structure or a buckle structure. When cleaning the garbage, the bolt or buckle structure is opened to make the door panel 122 in a rotatable state.

[0214] Referring to Figure 30 , start the tipping oil cylinder 17. The tipping oil cylinder 17 pushes the tipping frame 18 to rotate. The tipping frame 18 drives the whole carriage 12 to rotate. Under the action of gravity, the door panel 122 rotates relative to the carriage 12, and the garbage outlet 121 is opened, and the garbage can be discharged from the garbage outlet 121, and the transfer of the garbage can be realized.

[0215] Referring to Figure 31, in order to fully clean the garbage in the carriage 12, a garbage diversion plate 19 is provided inside the carriage 12, and the garbage diversion plate 19 is fixedly connected to the bottom wall of the carriage 12. A triangular prism-shaped diversion area is formed by enclosing between the garbage diversion plate 19 and the bottom wall of the carriage 12. That is, the garbage entering the carriage 12 can be concentrated within the space corresponding to the two garbage outlets 121 under the diversion and guiding action of the garbage diversion plate 19. When the entire carriage 12 is flipped, the garbage can be cleaned more thoroughly, avoiding a large amount of garbage remaining inside the carriage 12.

[0216] Refer to Figure 31 , in order to smoothly achieve the secondary utilization of the air flow, a splicing pipe 164 is provided between the main diversion pipe 162 and the sub-diversion pipe 163. The splicing pipe 164 is fixedly connected to the vehicle head 11 or the vehicle frame, and the sub-diversion pipe 163 is fixedly connected to and communicates with the splicing pipe 164. A hose 165 is connected to the lower end of the main diversion pipe 162. The hose 165 movably passes through the splicing pipe 164, and the outer side wall of the hose 165 abuts against the inner side wall of the splicing pipe 164 to minimize the gap between the hose 165 and the splicing pipe 164. Similarly, other sealing structures such as sealing sheets can also be provided inside the splicing pipe 164.

[0217] Refer to Figure 31 , it should be noted that when the carriage 12 is in a horizontal state, the sealing between the splicing pipe 164 and the hose 165 is ensured, and it does not affect the sliding of the hose 165 inside the splicing pipe 164. The length of the hose 165 can be set according to the specific flipping angle of the carriage 12. When the carriage 12 is in a horizontal state, part or all of the hose 165 passes through the splicing pipe 164.

[0218] The implementation principle of Embodiment 9 is as follows: During the flipping process of the carriage 12, the main diversion pipe 162 will drive the hose 165 to move synchronously, and part of the hose 165 is separated from the splicing pipe 164. During the reset process of the carriage 12, the hose 165 enters the splicing pipe 164 for storage. The air flow guiding structure does not affect the flipping of the carriage 12.
