Description

Technical Field

[0001] This utility model relates to a leaf sweeping device, specifically a leaf cleaning and processing vehicle. Background Technology

[0002] Autumn brings a large number of fallen leaves, which is very time-consuming for sanitation workers. In most cases, the fallen leaves are collected and disposed of in a centralized manner. However, the collection process is difficult and requires frequent loading and unloading. Because the leaves are fluffy, they are in an expanded state inside the transport vehicle, and the gaps between the leaves are large, requiring the transport vehicle to frequently go back and forth to load and unload, which is inefficient.

[0005] The suction crusher includes a housing, a rotating shaft, fan blades, and a rotating blade. The rotating shaft is rotatably mounted inside the housing. The fan blades and rotating blades are fixedly mounted on the rotating shaft from top to bottom. One side of the housing is connected to a collection box through a pipe, and an inlet pipe is provided at the bottom of the housing.

[0024] Example: As attached Figure 1 To be continued Figure 8 As shown, a leaf-collecting and processing vehicle includes a vehicle body and a power unit. The power unit includes an engine, a hydraulic system, and a generator. The engine drives the hydraulic system and the generator. The engine, hydraulic system, and generator in this application are all prior art, and their connection methods are also prior art, so they will not be described in detail. A leaf-collecting and processing device is installed at the end of the vehicle body away from the front. The leaf-collecting and processing device includes a drive system 1, a leaf-collecting and processing device 2, a leaf-removing device 3, and an operating lever 4. The drive system 1 drives the leaf-collecting and processing device 2 to collect leaves, and the drive system 1 also drives the leaf-removing device 3 to remove fallen leaves. The leaf cleaning operation is carried out by the control lever 4, which controls the start and stop of the leaf collection and processing device 2 and the leaf removal device 3. The leaf collection and processing device 2 includes a collection box 21, a suction and crushing device 22, and a collection device 23. The collection box 21 is used to hold leaves, the suction and crushing device 22 is used to crush leaves, and the collection device 23 is used to collect leaves on the ground into the collection box 21. The suction and crushing device 22 includes a hydraulic motor 221 and a suction crusher 222. The hydraulic system is used to drive the hydraulic motor 221 to rotate. The hydraulic motor 221 is connected to the suction crusher 222, and the hydraulic motor 221 drives the suction crusher 222 to work.

[0025] The hydraulic motor 221 is a device that converts hydraulic energy into mechanical energy. It belongs to existing technology and is widely used in various applications requiring rotary motion. It has the following advantages: 1. Hydraulic motors can provide very high torque and power output with relatively small size and weight; 2. Wide speed range: Hydraulic motors can operate smoothly over a wide speed range, achieving stepless speed regulation from extremely low to high speeds, and maintaining stable output torque at different speeds; 3. High efficiency: Modern hydraulic motor designs optimize internal structure, reducing leakage and friction losses, thus providing high working efficiency; 4. Simple maintenance: Hydraulic motors are typically compact with fewer parts, reducing maintenance complexity and cost. Furthermore, their good sealing performance makes it difficult for external contaminants to enter the interior, extending service life; 5. Constant torque output: Hydraulic motors can provide almost constant torque output over a wide speed range, which is crucial for applications requiring stable power output.

[0026] The suction crusher 222 includes a housing 2221, a rotating shaft 2222, a fan blade 2223, and a rotating blade 2224. The rotating shaft 2222 is rotatably mounted inside the housing 2221. The fan blade 2223 and the rotating blade 2224 are fixedly mounted on the rotating shaft 2222 from top to bottom. One side of the housing 2221 is connected to the collection box 21 through a pipe. An inlet pipe 2225 is provided at the bottom of the housing 2221.

[0027] The housing 2221 is internally fixedly equipped with a fixed blade 5 and a gathering ring plate 6. One end of the fixed blade 5 is fixedly connected to the inner wall of the housing 2221, and the other end of the fixed blade 5 is rotatably connected to the rotating shaft 2222. The gathering ring plate 6 is trumpet-shaped and is fixedly installed inside the housing 2221 near the leaf inlet pipe 2225. Multiple fixed blades 5 are provided and arranged around the rotating shaft 2222. The larger opening of the gathering ring plate 6 is close to the leaf inlet pipe 2225, and the smaller opening of the gathering ring plate 6 is close to the fixed blade 5. This arrangement can effectively gather fallen leaves and provide favorable conditions for crushing fallen leaves.

[0028] A partition 7 is provided between the fan blade 2223 and the rotating blade 2224. The partition 7 is densely covered with tiny ventilation holes. The partition 7 can prevent large pieces of fallen leaves from coming into contact with the fan blade 2223, and can effectively extend the service life of the fan blade 2223.

[0029] The collection device 23 includes a guide rod 231 and a collection cover 232. The guide rod 231 includes a transverse guide rod 2311, a longitudinal support rod 2312 and a mounting rod 2313. The transverse guide rod 2311 is rotatably connected to the vehicle body. The longitudinal support rod 2312 is fixedly installed at the bottom of the transverse guide rod 2311. The mounting rod 2313 is movably installed at the end of the transverse guide rod 2311 away from the vehicle body.

[0030] The bottom of the longitudinal support rod 2312 is movably equipped with a traveling wheel, and the inlet pipe 2225 is connected to the collection cover 232 through a pipe.

[0031] The collection cover 232 has a cut parallel to the ground. This design increases the contact area between the collection cover 232 and the leaves on the ground, allowing for more efficient absorption of the leaves.

[0032] The leaf removal device 3 includes a blower 31 and a cleaning pipe 32. The blower 31 is fixedly installed on the collection box 21, and the cleaning pipe 32 is fixedly installed on the air outlet of the blower 31. The diameter of the end of the cleaning pipe 32 away from the blower 31 is smaller than the diameter of the end of the cleaning pipe 32 connected to the blower 31. This arrangement can more effectively increase the pressure at the air outlet of the cleaning pipe 32, thereby achieving a more effective cleaning purpose.

[0033] This application has the following advantages in collecting fallen leaves by crushing them:

[0034] Easier to handle: The crushed leaves are significantly reduced in volume, making them easier to bag, transport, and store. This reduces processing time and labor intensity.

[0035] Accelerated decomposition: Smaller pieces of fallen leaves decompose faster than whole leaves. This is because microorganisms and other decomposers can access a larger surface area more quickly, thus accelerating the natural decay process.

[0036] Soil improvement: When crushed fallen leaves are mixed into the soil, they can increase the soil's structure and aeration as organic matter, while also helping to maintain soil moisture and provide nutrients, thus improving soil quality.

[0037] Making compost: Crushed fallen leaves are excellent for composting. They can be mixed with food scraps, grass clippings, and other organic waste to produce high-quality compost that can be used as a natural fertilizer for plants.

[0038] Reduce disease spread: Some pathogens or insect eggs may overwinter under intact fallen leaves. By breaking up and quickly disposing of these leaves, the risk of disease and pest outbreaks the following spring can be reduced.

[0039] Aesthetically pleasing and tidy: After being broken up, fallen leaves can be distributed more evenly on the surface of lawns or flower beds, without forming large piles that affect the landscape. They are also easy to clean up, maintaining the cleanliness of the environment.

[0040] Space saving: As mentioned earlier, due to its smaller size, more leaf material can be stored in the same space, which is especially important for people with limited storage space.

[0041] Environmental protection and energy conservation: Compared to burning fallen leaves, crushing and reusing fallen leaves is a more environmentally friendly option, which helps to recycle natural resources and reduce waste.
