Abstract
Description
Technical Field
[0001] This utility model relates to the field of special sanitation vehicles, and in particular to a leaf sweeper. Background Technology
[0002] In existing sanitation equipment, the removal of fallen leaves mainly relies on traditional brooms, dustpans, and some mechanized sweeping equipment. Most existing sweepers operate on narrow sections of roads between residential areas. These types of sweepers are generally small in size and have limited cargo capacity. When the sweeper starts working, it usually sucks the fallen leaves from the roadside into the cargo compartment for collection. However, because the area of a single fallen leaf is too large, the leaves sucked into the cargo compartment are in their original state. In this state, the leaves are large, and there is a lot of air between the overlapping leaves during the fall. This makes the large number of fallen leaves piled up in the cargo compartment in a loose state. As a result, the space inside the cargo compartment is difficult to utilize effectively, reducing the loading efficiency of the cargo compartment and increasing the workload of sanitation operations. Utility Model Content
[0003] The purpose of this utility model is to provide a leaf suction sweeper to address the problem in existing technologies where loose accumulation of fallen leaves inside the suction compartment reduces the efficiency of sanitation operations.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A leaf sweeping vehicle includes a sanitation vehicle, the sanitation vehicle including a cargo compartment, the top of the cargo compartment being equipped with a sweeping device; the sweeping device includes a suction section for sucking up fallen leaves; the sweeping device also includes a cutting section for crushing fallen leaves; the bottom of the suction section is connected to the top of the cutting section, and the bottom of the cutting section is connected to the top of the cargo compartment.
[0006] This utility model relates to a leaf sweeper, which cleans fallen leaves along the roadside by installing a suction and sweeping device with a suction section on the truck bed. This reduces the operational difficulty for construction workers and lightens the workload of sanitation workers. The suction and sweeping device also includes a cutting section that can crush the fallen leaves. The upper end of the cutting section is connected to the suction section to receive the fallen leaves sucked in by the suction section, and the lower end of the cutting section is connected to the truck bed to deliver the crushed leaves into the truck bed. This effectively solves the problem of fallen leaves occupying a large amount of truck bed space. By crushing the fallen leaves through the cutting section, the volume of the fallen leaves is greatly reduced, maximizing the utilization of the storage space inside the truck bed. As a result, the equipment no longer needs to frequently empty the truck bed during operation, greatly improving work efficiency.
[0007] As a preferred embodiment of the present invention, the cutting part includes a second receiving cavity, and a cutting blade assembly is provided in the second receiving cavity, with a driving device provided at one end of the cutting blade assembly.
[0008] By placing the cutter assembly inside the second receiving cavity, the pulverized leaf residue is prevented from drifting into the outside air when the cutter assembly cuts the fallen leaves; and a drive device is provided at one end of the cutter assembly, which can provide power to the cutter.
[0009] As a preferred embodiment of the present invention, the cutter assembly includes a rotating shaft connected to the second receiving cavity; the rotating shaft is provided with a plurality of cutters.
[0010] The shaft is connected to the drive unit to ensure that the power of the drive unit can be transmitted to the cutter, ensuring that the cutter can work. The shaft is equipped with multiple cutters, so that after the fallen leaves are sucked in, they can be cut by multiple cutters at the same time, which improves the cutting efficiency and allows the fallen leaves to be crushed in a relatively short time.
[0011] As a preferred embodiment of the present invention, the suction part includes a first receiving cavity, a corrugated tube is provided on one side of the first receiving cavity, one end of the corrugated tube is connected to the first receiving cavity, and a protective shell is provided at the other end.
[0012] The corrugated pipe serves as a channel for sucking up fallen leaves. Its ability to stretch to varying degrees allows sanitation workers to adjust its length according to site requirements, ensuring a closer fit between the pipe opening and the leaf-covered area, thus improving work efficiency. Protective sleeves at the pipe ends effectively prevent accidental contact and collisions during operation, protecting the pipe ends from damage.
[0013] As a preferred embodiment of this utility model, the protective shell is provided with a handle, and the handle and the protective shell form an angle.
[0014] By setting a handle on the protective shell, sanitation workers can directly grasp the handle to control the direction of the corrugated pipe. The angle design between the handle and the protective shell allows the operator to operate with a more natural hand posture, reducing hand fatigue and improving comfort during long-term work.
[0015] As a preferred embodiment of this utility model, a fixing ring is provided on the side of the carriage, the fixing ring has an opening, and the fixing ring is used to fix the corrugated pipe.
[0016] When the corrugated pipe is not in use, the retaining ring can securely fasten it to one side of the carriage, preventing it from loosening or being damaged during transportation. This design improves the safety of the equipment during transport and reduces the risk of damage.
[0017] As a preferred embodiment of the present invention, a fan chamber is provided inside the first receiving cavity, and a fan is provided inside the fan chamber. The fan is used to create negative pressure inside the first receiving cavity.
[0018] By generating negative pressure within the first receiving cavity, the blower effectively enhances the suction force of the suction unit, thereby improving the ability to remove fallen leaves and debris. The formation of negative pressure allows fallen leaves and debris to be sucked into the first receiving cavity more quickly and thoroughly, reducing the chance of omissions during the cleaning process and thus improving the efficiency and quality of sanitation operations.
[0019] As a preferred embodiment of this utility model, the wind turbine nacelle is provided with an isolation net at one end facing the corrugated pipe, and the wind turbine is positioned facing the isolation net.
[0020] Setting up an isolation net can effectively prevent fallen leaves from entering the fan and causing it to malfunction.
[0021] As a preferred embodiment of this utility model, the top of the carriage is provided with an entrance channel, one end of which is connected to the carriage and the other end of which is connected to the cutting section.
[0022] The tapered inlet channel gradually narrows in shape, which guides the crushed leaves to slide smoothly into the carriage, avoiding material accumulation or blockage during transportation and ensuring a smooth transportation process.
[0023] As a preferred embodiment of this utility model, the environmentally friendly vehicle is equipped with a power source, which is connected to the drive device and the fan respectively.
[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0025] 1. This utility model relates to a leaf sweeper, which cleans fallen leaves along the roadside by installing a suction and sweeping device with a suction section on the truck bed.

[0038] Example 1
[0039] like Figures 1 to 2 The illustration shows a leaf sweeping vehicle, which includes a sanitation vehicle and a cargo compartment 1 for loading fallen leaves. The top of the cargo compartment 1 is equipped with a sweeping device 2, which can suck fallen leaves from the roadside into the cargo compartment 1. The sweeping device 2 includes a suction section 21, and a corrugated pipe 212 is provided on one side of the suction section 21, through which the sweeping device 2 is connected to the external environment. The sweeping device 2 also includes a cutting section 3, and the top of the cutting section 3 is connected to the bottom of the suction section 21, and the bottom of the cutting section 3 is connected to the top of the cargo compartment 1.
[0040] The top of the cutting section 3 is connected to the bottom of the suction section 21. After the fallen leaves enter the cutting section 3 through the suction section 21, they are crushed by the cutting section 3. The lower end of the cutting section 3 is connected to the top of the carriage 1, and the crushed fallen leaves directly enter the carriage 1 through the cutting section 3. Because the fallen leaves are crushed by the cutting section 3, their volume is greatly reduced, significantly reducing the space occupied by the fallen leaves in the carriage 1. This design maximizes the storage capacity of the carriage 1, allowing the equipment to work continuously for a longer period of time without frequent shutdowns to empty the carriage, thereby greatly improving the efficiency of the cleaning operation. Specifically, after the fallen leaves are sucked in by the suction section 21, they are crushed by the cutting section 3, transforming the originally loose form that occupied a lot of space into smaller fragments, allowing the carriage 1 to carry more fallen leaves. In this way, the equipment no longer needs to frequently empty the carriage in large-area operation scenarios, significantly improving the continuity and efficiency of sanitation operations and reducing the workload of operators. In addition, reducing the number of times the carriages need to be emptied not only improves the operating efficiency of the equipment, but also reduces the energy consumption and maintenance costs of the equipment, further enhancing the economic efficiency and environmental friendliness of the equipment.
[0041] In an optional embodiment, the cutting section 22 includes a second receiving cavity 221, within which a cutting assembly 222 is provided. By placing the cutting assembly 222 within the second receiving cavity 221, the pulverized leaves can all enter the carriage 1 when the cutting assembly 222 cuts the fallen leaves, preventing the leaves from scattering during the pulverization process. One end of the cutting assembly 222 is also equipped with a driving device 223 that drives the cutting assembly 222 to operate. Through the driving device 223, the cutting assembly 222 can efficiently rotate and cut the fallen leaves, ensuring that the leaves are quickly pulverized after passing through the suction and sweeping device 2. The driving device 223 can be powered by an electric motor or other power equipment, ensuring that the equipment maintains efficient operation under different working conditions.
[0042] Furthermore, the cutter assembly 222 includes a rotating shaft 2221 connected to the second receiving cavity 221. The rotating shaft 2221 is equipped with several cutters. When the drive device 223 is activated, the rotating shaft 2221 rotates, causing the cutters in the cutter assembly 222 to cut the fallen leaves at high speed. Figure 2 and Figure 5 As shown.
[0043] In an optional embodiment, the suction unit 21 includes a first receiving cavity 211 for collecting fallen leaves, and one end of the corrugated pipe 212 is connected to the first receiving cavity 211, while the other end is provided with a protective shell 2121. This protective shell 2121 has a rigid structure. By providing a protective shell 2121 on the corrugated pipe 212, the problem of reduced leaf cleaning efficiency caused by long-term contact between the corrugated pipe 212 and the ground during use by sanitation workers can be effectively prevented. Figure 2 and Figure 3 As shown.
[0044] In an optional embodiment, the protective shell 2121 is provided with a handle 2122, and the handle 2122 and the protective shell 2121 form an angle. By providing a handle 2122 on the protective shell 2121, sanitation workers can directly grasp the handle 2122 to control the direction of the corrugated pipe 212. The angle design between the handle 2122 and the protective shell 2121 allows the operator to operate with a more natural hand posture when holding it, reducing hand fatigue and improving the comfort of long-term work.
[0045] Furthermore, a fixing ring 12 is provided on one side of the carriage 1, and an opening 121 is provided at one end of the fixing ring 12. This allows sanitation workers to insert the corrugated pipe 212 into the fixing ring 12 through the opening 121 after using it. The handle 2122 is set at an angle to the protective shell 2122 of the corrugated pipe, so that the corrugated pipe 212 can be locked into the fixing ring 12 by the angle, preventing the corrugated pipe 212 from falling out.
[0046] In an optional embodiment, a fan chamber is provided within the first receiving cavity, and a fan is installed inside the fan chamber. The function of the fan is to improve the working efficiency of the cleaning system by creating negative pressure within the first receiving cavity. The generation of negative pressure helps to enhance the suction force of the suction unit, allowing fallen leaves and debris to be sucked into the first receiving cavity more quickly. The negative pressure environment not only makes the suction force stronger but also makes the airflow smoother, thereby significantly improving cleaning efficiency. At the same time, the formation of negative pressure also reduces the probability of debris being missed during the sweeping process, ensuring that fallen leaves and debris are removed more thoroughly, greatly improving the quality and efficiency of sanitation operations.
[0047] Furthermore, an isolation net is designed at the end of the blower compartment facing the bellows, with the blower installed facing the net. The isolation net effectively prevents large leaves and debris from entering the blower, avoiding damage or disruption to its normal operation. When larger objects are sucked in during cleaning, the isolation net promptly blocks them from entering the blower without obstructing airflow, ensuring the blower remains in optimal working condition. This protects the blower's normal operation, extends its service life, and ensures the entire cleaning system operates continuously in a highly efficient and safe manner. Figures 2 to 4 As shown.
[0048] In an optional embodiment, an entrance channel is designed on the top of the carriage. One end of the entrance channel communicates with the interior cavity of the carriage, and the other end connects to the cutting section. The existence of the entrance channel allows the cut material to be smoothly transferred from the cutting section to the interior of the carriage, realizing continuous flow of material from processing to storage. To further optimize the transfer efficiency, the entrance channel adopts a conical structure design, with the width of the channel gradually decreasing from the cutting section towards the carriage. This conical structure design can effectively guide the smooth flow of material during the transfer process; the gradual narrowing of the conical channel not only plays a guiding role but also effectively controls the flow speed of the material, allowing the crushed leaves to slide into the carriage at a suitable speed, preventing material from accumulating in the channel. Figures 1 to 4 As shown.
[0049] In an optional embodiment, the environmentally friendly vehicle is equipped with a power source, which is connected to both the drive unit and the fan.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
