Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicle technology, specifically a cleaning vehicle that can automatically collect fallen leaves. Background Technology

[0002] In modern urban landscaping maintenance, leaf sweeping is a common and necessary task. Especially in autumn, trees shed a great deal of leaves. If these leaves are not cleared in time, the aesthetics of the garden environment may decline, affecting the visitor experience. Furthermore, rotting leaves may breed pests and diseases, negatively impacting plant growth.

[0003] Patent CN218204124U discloses a garden leaf collection vehicle, including a vehicle body, an expansion device at the bottom of the left side of the vehicle body, a crushing device fixedly installed on the upper surface of the vehicle body, a pusher fixedly installed above the right side of the vehicle body, a collection box movably installed below the right side of the vehicle body, wheels fixedly installed at the bottom of the vehicle body, and a suction fan fixedly installed inside the vehicle body. The design utilizes a cylinder to push a square plate to slide, which in turn drives transmission rods connected to L-shaped rods on both sides. The movement of the L-shaped rods extends the brush rollers on both sides, expanding the cleaning range. The exhaust port of the suction fan drives the fan blades to rotate, which in turn drives a threaded rod to rotate, crushing the fallen leaves. The fan blades drive a rotating rod to rotate inside the U-shaped rod, and through pulleys on both sides and the M-shaped groove of the rotating rod, pushes a push rod to move, pressing the crushed leaves and preventing blockage.

[0004] In practical use, the aforementioned existing technology requires the fan blades to be driven by the airflow generated by the exhaust end of the suction fan, and the two threaded rods need to be driven by the rotation of the fan blades. This requires the suction fan to generate a large airflow. However, when a large airflow is generated at the exhaust end of the suction fan, the air pressure in the pulverizing chamber increases. The airflow in the pulverizing chamber of the pulverizing device cannot be discharged, which will seriously affect the operation of the suction fan. Furthermore, the airflow will cause the pulverized leaves to float in the pulverizing chamber, affecting the meshing transmission of the gears and easily leading to equipment failure. This has significant usage defects. In view of this, we propose a cleaning vehicle that can automatically collect fallen leaves. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning vehicle that can automatically collect fallen leaves, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0047] In this embodiment, the cleaning cart that automatically collects fallen leaves is used by the operator. The operator pushes the cart to the desired location, then starts the motor 32 and exhaust fan 61. The exhaust fan 61 expels air from the collection box 2, creating negative pressure inside. This generates suction at the opening of the leaf suction hood 5. The motor 32 drives the rotating shaft 33 to rotate, which in turn drives multiple cutters 34 to rotate. The operator then holds the handle 50 and aligns the leaf suction hood 5 with the fallen leaves on the ground. Due to the negative pressure inside the collection box 2, suction is generated at the opening of the leaf suction hood 5. The system automatically sucks in fallen leaves, which enter the feed pipe 30 through the corrugated hose 4. Multiple cutters 34 shred the leaves, and the shredded leaves enter the collection box 2 with the airflow. When there are many shredded leaves in the collection box 2, the operator uses the compaction component 7 to move the rectangular extrusion plate 70 downward through the rectangular rod 72 to compact the shredded leaves in the collection box 2, thereby saving space and increasing the capacity of the collection box 2. When there are enough leaves in the collection box 2, the controller is turned off, the discharge baffle 8 is removed, the discharge port 20 is opened, and the leaves are taken out or transferred to the designated processing area.
