Description

Technical Field

[0001] This utility model relates to the field of sanitation equipment technology, and more specifically, to a leaf sweeping and collection device for road sanitation. Background Technology

[0002] With the advancement of ecological civilization construction and the year-by-year increase in urban green coverage, the number of trees planted along urban roads, in parks and communities in my country has increased significantly. According to data from the Ministry of Housing and Urban-Rural Development, the green coverage rate of urban built-up areas nationwide reached 42.5% in 2023, of which deciduous trees accounted for more than 60%. While this situation has improved the urban ecological environment and enhanced the quality of life for residents, it has also brought seasonal challenges to road sanitation operations. Every autumn to early winter, a large number of fallen leaves naturally fall and accumulate on the road surface, sidewalk gaps, drainage outlets and the edges of green belts, creating continuous pressure on sanitation operations.

[0003] In autumn, the accumulation of fallen leaves on both sides of the road not only affects the aesthetics of the urban environment but may also clog drainage outlets during rainy days, posing a safety hazard. Currently, the cleaning of fallen leaves on the road mainly relies on manual sweeping or traditional sweeping vehicles. Manual sweeping is inefficient, labor-intensive, and easily generates dust during the process, affecting the health of sanitation workers and air quality. Traditional sweeping vehicles are large and cannot reach into road gaps, sidewalk edges, and other areas, resulting in incomplete cleaning. At the same time, the fallen leaves in the collection bins are loose, resulting in low space utilization and requiring frequent emptying, further reducing operational efficiency.

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a road sanitation leaf sweeping and collection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a road sanitation leaf sweeping and collection device, comprising a vehicle body, a collection chamber at the top of the vehicle body, a conveying chamber at the bottom of the vehicle body, and a sweeping mechanism for gathering fallen leaves from the ground towards the center on one side of the conveying chamber.

[0006] The collection chamber is equipped with a compression component for compressing the volume of fallen leaves;

[0007] The conveying bin is equipped with a conveying assembly for conveying fallen leaves into the collection bin.

[0008] In a preferred embodiment, the sweeping mechanism includes a motor, an electric push rod is rotatably mounted on the bottom of the vehicle body, a rotating rod is rotatably connected to the telescopic end of the electric push rod, one end of the rotating rod is rotatably mounted on the bottom of the vehicle body, the other end of the rotating rod is connected to the motor, the output end of the motor is connected to a mounting base, and a brush is provided at the bottom of the mounting base.

[0009] In a preferred embodiment, the compression assembly includes a collection box, the inner top wall of which is provided with an electric push rod II, the telescopic end of which is connected to a lower pressure plate, the collection box is movably installed inside the collection box, and the outer wall of the lower pressure plate is tightly fitted to the inner wall of the collection box.

[0010] In a preferred embodiment, the conveying assembly includes a second motor, which is disposed on one side of the conveying bin. A conveyor belt is disposed inside the conveying bin, and a plurality of baffles are disposed on the conveyor belt. The output end of the second motor is connected to the conveyor belt for transmission. A feed hopper is disposed on the top of the conveying bin, and an exhaust fan is disposed on the top of the feed hopper. A conveying pipe is disposed on the top of the exhaust fan, and the other end of the conveying pipe is connected to a collection bin.

[0011] In a preferred embodiment, a waste liquid tank is provided at the bottom of the vehicle body, the interior of the waste liquid tank is connected to a collection chamber, a filter screen is provided at the bottom of the collection chamber, and a drain pipe is provided at the bottom of the waste liquid tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] From the current actual scenario of road leaf sweeping, the existing operation methods are mainly divided into two categories: manual sweeping and mechanical sweeping. However, both have obvious limitations. Manual sweeping, as a traditional operation mode, is still widely used in areas that are difficult for machinery to reach, such as sidewalks, narrow alleys in old urban areas, and around green belts. It relies on sanitation workers to carry out the work with brooms and dustpans. On average, each person can only sweep about 200-300 square meters of road surface per hour, which is extremely inefficient. Moreover, during the sweeping process, the fallen leaves are easily turned over and generate a lot of dust, which not only includes dead branches and debris, but also road dust, residual particles from vehicle exhaust, etc. Long-term exposure can increase the probability of sanitation workers suffering from respiratory diseases by more than 30%. At the same time, the spread of dust will also affect the surrounding air quality, which is contrary to the requirements of urban air pollution prevention and control. In addition, manual sweeping requires frequent bending over and back and forth to empty the fallen leaves, which is labor-intensive. The continuous operation time at one time is usually no more than 4 hours, which is difficult to meet the needs of large-area and high-intensity leaf cleaning.

[0023] Mechanical sweeping mainly uses large sweepers. Although they are suitable for rapid sweeping of main urban roads, the width of large sweepers generally exceeds 2.5 meters and the minimum turning radius is greater than 5 meters. They cannot enter sidewalks with a width of less than 3 meters, internal roads in communities, and back streets and alleys in old urban areas. This makes these areas blind spots for sweeping. The long-term accumulation of fallen leaves can easily breed mosquitoes and insects, and can also block roadside drains and cause local water accumulation when it rains.

[0024] In addition to the two main methods mentioned above, some areas have tried using small handheld hair dryers to assist in cleaning. However, this device can only push fallen leaves to a designated area and cannot collect them. They still need to be manually bagged afterward. Moreover, the noise level of the hair dryer can reach more than 85 decibels when it is working, which exceeds the urban environmental noise standard (≤55 decibels during the day) and disturbs the lives of surrounding residents.

[0025] As attached Figure 1 To be continued Figure 4 The illustrated road sanitation leaf sweeping and collection device includes a vehicle body 1, a sweeping mechanism at the bottom front end of the vehicle body 1, a conveying chamber 3 at the bottom middle, and a collection chamber 2 at the top rear end of the vehicle body 1.

[0026] To allow the cleaning mechanism to adjust the cleaning range as needed, an electric push rod 11 is rotatably mounted at the bottom of the vehicle body 1. A rotating rod 10 is rotatably connected to the telescopic end of the electric push rod 11. One end of the rotating rod 10 is rotatably mounted at the bottom of the vehicle body 1. The extension and retraction of the electric push rod 11 drives the rotating rod 10 to rotate. Two sets of electric push rods 11 and rotating rods 10 are provided, and each rotating rod 10 has a motor 4 at its other end. The output ends of both motors 4 are connected to mounting bases. Brushes 6 are mounted at the bottom of both mounting bases 5. The two motors 4 rotate in opposite directions. Starting the motors 4 drives the mounting bases 5 to rotate, causing the two brushes 6 to rotate in opposite directions, both facing towards the center. This gathers fallen leaves between the two brushes 6 for easy collection. The cleaning position of the brushes 6 changes with the position of the rotating rod 10, thus adjusting the position between the two brushes 6 and achieving the effect of adjusting the cleaning area.

[0027] To collect the fallen leaves gathered at the bottom of the vehicle body 1 into the collection bin 2, a conveyor belt 17 is installed inside the conveyor bin 3. A motor 2 7 for driving the conveyor belt 17 is installed on one side of the conveyor bin 3. The opening of the conveyor bin 3 faces the cleaning mechanism. A feed hopper 9 is installed on the conveyor bin 3. An exhaust fan 16 is installed on the top of the feed hopper 9. A conveying pipe 8 is installed on the top of the exhaust fan 16. The other end of the conveying pipe 8 is connected to the collection bin 2. The conveyor bin 3 is connected to the interior of the collection bin 2 through the conveying pipe 8. The conveyor belt 17 is set at an angle, with the bottom of the conveyor belt 17 facing the cleaning mechanism and the top of the conveyor belt 17 facing the exhaust fan 16. Activating the exhaust fan 16 will suck the fallen leaves on the conveyor belt 17 into the collection bin 2.

[0028] To prevent fallen leaves from falling out of the conveyor hopper 3 during leaf transport and thus affecting the leaf transport speed, several baffles 18 are installed on the conveyor belt 17. The baffles 18 are made of elastic material and are set at an angle to the conveyor belt 17. When the brush 6 gathers the fallen leaves towards the center, the leaves first accumulate on the baffles 18 and then are transported upward along the conveyor belt 17. As the leaves are transported upward, due to gravity, they fall downward into the angle between the baffles 18 and the conveyor belt 17, preventing them from falling out of the conveyor hopper 3. Furthermore, when the exhaust fan 16 extracts fallen leaves, it can only extract the leaves between the baffles 18 directly below the exhaust fan 16. This controls the number of leaves entering the feed pipe at one time, preventing a large number of leaves from being extracted at the same time, which could cause the exhaust fan 16 to become clogged and affect the cleaning speed.

[0029] To enable the collection chamber 2 to collect more fallen leaves at a time, an electric push rod 14 is installed on the inner top wall of the collection chamber 2. The telescopic end of the electric push rod 14 is connected to the lower pressure plate 13. A collection box 12 is installed inside the collection chamber 2. The outer wall of the lower pressure plate 13 is tightly fitted to the inner wall of the collection box 12. The electric push rod 14 pushes the lower pressure plate 13 downward to compress the fallen leaves stored in the collection box 12, which can reduce the gaps between the fallen leaves, improve the utilization rate of the internal space of the collection box 12, and enable the collection box 12 to store more fallen leaves. A door can be hinged to one side of the collection chamber 2. By opening the door, the collection box 12 can be easily removed and the fallen leaves can be emptied.

[0030] In order to collect more fallen leaves, a waste liquid tank 15 is provided at the bottom of the vehicle body 1. The interior of the waste liquid tank 15 is connected to the collection chamber 2. A filter screen 121 is provided at the bottom of the collection tank 12 to prevent fallen leaves from passing through. When the fallen leaves are squeezed downwards, the water in the fallen leaves flows into the waste liquid tank 15 through the filter screen 121, thereby reducing the moisture content of the fallen leaves in the collection tank 12 and facilitating the subsequent processing of the fallen leaves. A drain pipe 19 is provided at the bottom of the waste liquid tank 15 to facilitate the discharge of waste liquid.

[0031] In order to prevent the fallen leaves entering the collection chamber 2 from affecting the operation of the electric push rod 2 14, a baffle 21 is provided on one side of the electric push rod 2 14. The baffle 21 can block the fallen leaves entering the collection chamber 2 and prevent the fallen leaves from contacting the electric push rod 2 14.

[0032] To prevent fallen leaves from floating upwards and affecting the operation of the electric push rod 11 above when sweeping leaves, a baffle 31 is installed on one side of the conveying chamber 3. The baffle 31 can block the upward-floating leaves.

[0033] This utility model uses a small vehicle body 1 as a carrier, which can enter relatively narrow areas such as sidewalks and non-motorized vehicle lanes on main roads during actual operation. An electric push rod 11 is rotatably mounted on the vehicle body 1. The electric push rod 11 pushes the rotating rod 10 to rotate, thereby adjusting the position between the two brushes 6. During use, the cleaning range of the brushes 6 can be adjusted according to the environment, gathering fallen leaves from both sides and the front of the vehicle body 1 towards the center, suitable for different cleaning areas. A conveyor belt 17 is set to quickly collect the gathered fallen leaves into the collection bin 2. Several baffles 18 are set on the conveyor belt 17 to... The system prevents fallen leaves from falling during upward transport and limits the number of leaves transported at one time, thus avoiding large amounts of leaves clogging the exhaust fan 16 and increasing the leaf transport speed. By setting a pressure plate 13 in the collection chamber 2, the electric push rod 14 pushes the pressure plate 13 to squeeze the fallen leaves in the collection chamber 2, which can reduce the gaps between the fallen leaves, improve the space utilization of the collection box 12, increase the number of fallen leaves that can be stored in the collection box 12 at one time, and reduce the number of times the fallen leaves are dumped. The liquid that seeps out from the squeezed fallen leaves is collected in the waste liquid tank 15 for easy treatment of waste liquid. It has the effect of being suitable for cleaning needs in different environments and improving cleaning speed.
