Description

[Technical Field]

[0001] The present invention relates to a cleaning device for sucking and collecting fallen leaves and other debris outdoors, particularly on roads, in parks, and the like. [Background technology]

[0002] Conventionally, cleaning devices for collecting outdoor trash that are mounted on vehicles are known. For example, according to Patent Document 1, the cleaning device includes a tank containing a dust bag for collecting collected trash, a suction pipe connected to the dust bag via a suction port provided in the tank, and a blower connected to the outside of the tank via an exhaust port provided in the tank. The blower sucks air from inside the tank, and the trash is sucked up through the suction pipe. The sucked trash is collected in the dust bag inside the tank. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-40476 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional cleaning devices, a blower is installed downstream of the dust bag, so as the amount of dust in the dust bag increases, the suction force of the suction pipe decreases.

[0005] An object of the present invention is to provide a cleaning device that can prevent a decrease in suction power even when the amount of collected garbage increases. [Means for solving the problem]

[0006] This invention is a cleaning device comprising a housing, a fan provided inside the housing, an intake section located upstream of the fan, an exhaust section located downstream of the fan, and an intake duct that can be attached to the intake section, wherein a garbage bag is attached to the exhaust section, and the intake section is located above the bottom surface of the housing, thereby forming a storage section on the bottom surface. The debris passes through the fan blades and is collected downstream of the fan, so there is no reduction in suction power due to clogging upstream of the fan. In addition, heavy debris such as pebbles and branches accumulate in the storage area, preventing damage to the fan blades by these pebbles.

[0007] The suction duct has a base end connected to the suction portion of the housing and a tip end located opposite the base end, and the tip end is characterized by having an extension piece extending from the tip edge. The extension piece collects the garbage, allowing for efficient collection.

[0008] The housing is mounted on a loading platform of a vehicle body, and the exhaust portion and the tip of the intake duct are disposed outside the vehicle body. By loading the cleaning device onto the loading platform of the vehicle, it is possible to collect garbage while moving around in the vehicle. [Effects of the Invention]

[0009] The cleaning device of this invention has an intake duct upstream of the fan and a garbage bag downstream, so that debris such as dead leaves sucked in through the intake duct passes through the fan and is collected in the garbage bag. Therefore, even if debris accumulates in the garbage bag, the suction power does not decrease. Furthermore, heavy debris such as branches and pebbles can be dropped into a storage area in front of the fan, preventing damage to the fan by these branches and pebbles. [Brief explanation of the drawings]

[0010] [Figure 1] FIG. 1 is a schematic diagram of a cleaning device in use. [Figure 2]FIG. 2 is a top view of the cleaning device of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0011] (Cleaning device 1) Fig. 1 is a schematic diagram of cleaning device 1 placed on the bed of truck T, and Fig. 2 is a diagram of cleaning device 1 viewed from above with truck T omitted from Fig. 1. Cleaning device 1 comprises a housing 2, a fan 3 provided inside housing 2, an intake section 21 located upstream of fan 3 and opening into housing 2, an exhaust section 22 located downstream of fan 3 and opening into housing 2, and an intake duct 4 attachable to intake section 21. A garbage bag is attached to exhaust section 22.

[0012] (Chassis 2 and Fan 3) The fan 3 is attached inside the housing 2. The fan 3 is installed in the fan mounting portion 23 between the intake portion 21 and the exhaust portion 22. The fan mounting portion 23 has a top surface 23a, a bottom surface 23b, and both side surfaces 23c, and its cross section is generally rectangular. The fan 3 has a generally rectangular outer frame and is installed so as to fit snugly within the top surface 23a, bottom surface 23b, and both side surfaces 23c of the fan mounting portion 23. The opening areas of the intake portion 21 and the exhaust portion 22 are smaller than the cross-sectional area of ​​the fan mounting portion 23, and the intake portion 21 is positioned above the bottom surface 23b of the fan mounting portion 23, thereby forming a storage portion 24 on the bottom surface 23b. More specifically, the storage portion 24 is provided on the bottom surface 23b between the intake portion 21 and the fan mounting portion 23. In this embodiment, a slope 25 is provided that slopes downward from the intake portion 21 toward the storage portion 24. The storage section 24 is provided with an opening / closing door 24a, which allows the storage section 24 to be open to the outside.

[0013] (Intake duct 4) The intake duct 4 has a base end 41 connected to the intake section 21 of the housing 2 and a tip end 42 located on the opposite side of the base end 41, and the tip end 42 has an extension piece 43 extending from the tip edge.

[0014] (Installed in a vehicle) The cleaning device 1 can be used by being loaded onto the loading platform of a vehicle such as a truck. More specifically, the housing 2 is fixed to the loading platform so that the suction unit 21 is located forward in the direction of travel of the vehicle and the discharge unit 22 is located rearward. In this case, the discharge unit 22 extends from the loading platform and has an opening facing the ground. A garbage bag (not shown) is attached to the discharge unit 22. A breathable net or the like is used as the garbage bag. The suction duct 4 can be fixed to the loading platform so that the tip 42 faces the ground. When fixing to the loading platform, it is desirable to use a separate fixing device. The suction duct 4 is positioned so that the extension piece 43 is located rearward in the direction of travel. By positioning it in this way, the extension piece 43 can efficiently collect fallen leaves and the like like a dustpan. Note that by making the suction duct 4 a flexible tube, it may be possible for the worker to hold it directly without fixing it to the loading platform. The drive source of the fan 3 can also be loaded onto the bed of the vehicle.

[0015] With the cleaning device 1 described above, by starting the drive source and rotating the fan 3, it is possible to suck in debris such as dead leaves from the tip 42 of the suction duct 4. The sucked-in dead leaves slip between the blades of the fan 3 and are blown downstream to the discharge section 22. The blown-off dead leaves are collected in a garbage bag from the discharge section 22. Because the debris accumulates downstream of the fan 3, the suction force is not reduced due to debris accumulation or clogging, and the desired suction force can be obtained at all times.

[0016] While debris such as dead leaves passes directly through the blades of the fan 3, heavy debris such as branches and pebbles flow into the housing 2 from the intake duct 4, then drop to the bottom surface 23b, roll down the inclined portion 25, and flow into the storage section 24. This prevents branches, pebbles, etc. from getting caught in the fan 3 and damaging it. The storage section 24 is provided with an openable door 24a, which allows accumulated branches and pebbles to be removed. Note that the openable door 24a is not an essential component and may be kept open at all times. In this embodiment, the storage section 24 is cylindrical and opens to the bottom surface 23b, but debris may also be stored directly on the bottom surface 23b.

[0017] By loading the cleaning device 1 as described above onto the bed of a truck T, it is possible to clean up dead leaves by simply placing the tip 42 of the suction duct 4 on top of dead leaves that have accumulated on the side of the road and driving the truck T forward. In particular, the extension piece 43 can efficiently guide the dead leaves into the suction duct 4. Since workers can collect dead leaves simply by driving the truck T, cleaning work can be carried out easily. In addition, the suction duct 4 can be removed from the bed of the truck T and used, making it possible to clean places that the truck T cannot enter. [Explanation of symbols]
