A device for collecting rubbish using a vehicle comprises a working member and a collector housing (1). The collector housing (1) is in the form of a hollow arc with a discharge opening (3), said arc being mounted on the vehicle, in a rear wing arch, wherein the concave side of the hollow arc of the storage housing (1) is oriented towards a vehicle wheel and is provided with n rubbish-capturing blades (2) which are arranged at an acute angle a to the surface of the collector housing (1) at a distance from one another. A movable vehicle wheel serves as the working member of the device. On account of a centrifugal force which can be created during movement of the wheels of a car, the proposed technical solution makes it possible to collect rubbish which has accumulated on the roadway.
Description
Устройство для сбора мусора с использованием транспортного средства Device for collecting garbage using a vehicle
Полезная модель модель относится к устройствам и приспособлениям для уборки мусора, в которых используется созданный разными способами воздушный поток. Такие устройства установлены, преимущественно, на колесах с возможностью их перемещения по убираемой территории или по проезжей части дороги, или по тротуару. The utility model refers to the devices and devices for garbage collection that use the airflow created by various means. Such devices are installed mainly on wheels with the possibility of moving them around the cleaned area or along the carriageway, or along the sidewalk.
Машины для сбора мусора известны на протяжении многих лет. В таких машинах используют сложную систему всасывания, которая отличается входным отверстием для всасывания, расположенным вблизи от обрабатываемой поверхности. Trash collection machines have been known for many years. Such machines use a complex suction system, which is characterized by an inlet for suction located near the surface to be treated.
Известен мусоровоз, содержащий бункер для транспортировки мусора с гидроподъемником, бункер для сбора дорожного мусора, манипулятор для подъема и опрокидывания бункеров с бытовым мусором в бункер для транспортировки мусора (См. авт. с-во СССР JYO 1650487, МПК В 60 Р 1/48, 1991г.). A garbage truck containing a bunker for transporting garbage with a hydraulic lift, a bunker for collecting road garbage, a manipulator for lifting and tipping bins with household garbage into a bunker for transporting garbage is known (See author JYO 1650487, IPC H 60 P 1/48 , 1991).
Кроме этого, известны машины для подметания проезжей части, которые перемещают мусор к бордюру тротуара. А также машины, осуществляющие вакуумную уборку дорожного мусора. Указанные уборочные машины слишком сложные и громоздкие, ненадежны в эксплуатации, энергоемкие и дорогие. In addition, the car for sweeping the roadway, which move the garbage to the sidewalk curb, is known. And also the cars which are carrying out vacuum cleaning of road garbage. These cleaners are too complicated and bulky, unreliable in operation, energy-intensive and expensive.
Известен рабочий орган уборочной машины, содержащий, приводной диск с ворсом, связаный с механизмом подвески, устройство для разрежения воздуха, имеющее всасывающее сопло (См. авт. с-во СССР JVs 1008340,МПК Е 01 Н 1/08, 1978г.).
Рабочий орган выполнен в виде у отдельных труб - всасывающих сопел с торцами, срезанными под углом. Рабочий орган опирается на ворс щетки, которая вращается. Known working body of the harvesting machine, containing, a drive disk with a pile, associated with the mechanism of the suspension, a device for air dilution, having a suction nozzle (See the author. USSR JVs 1008340, MPK E 01 H 1/08, 1978). The working body is made in the form of individual pipes - suction nozzles with ends cut at an angle. The working body rests on the pile of the brush, which rotates.
Такая конструкция не забезпечуе достаточную эффективность всасывания мусора из рабочей зоны при ее значительном объеме. При этом сопутствующий мелкий мусор, включая мелкие фракции песка, поступать во всасывающие сопла не будет. Кроме того, оборудование обладает большой энергоемкостью и громоздкостью. Such a design does not ensure sufficient efficiency of suction of garbage from the working area with its considerable volume. At the same time the accompanying small garbage, including small fractions of sand, will not enter the suction nozzles. In addition, the equipment has high energy consumption and bulkiness.
Известна машина для сбора мусора, состоящая из бункера, связаное с его полостью входное сопло, закрепленный на бункере воздушный насос, рабочая полость которого сообщается с полостью бункера (См.патент Российской Федерации Ns 2090691, МПК Е01Н 1/08, Е01Н 8/00, 1995г.). A known garbage collection machine consisting of a bunker, an inlet nozzle connected to its cavity, an air pump attached to the bunker, the working cavity of which communicates with the cavity of the bunker 1995).
Оборудование машины имеет достаточно высокую энергоемкость, поскольку работа воздушного насоса будет эффективной лишь при сравнительно большой затрате воздуха и высокой производительности насоса. Кроме того, оборудование некомпактное, что отрицательно влияет на его маневренность, производительность и способность работать в труднодоступних местах. The equipment of the machine has a sufficiently high energy consumption, since the operation of the air pump will be effective only with a relatively large expenditure of air and high pump performance. In addition, the equipment is not compact, which negatively affects its maneuverability, performance and ability to work in hard-to-reach places.
Наиболее близким по технической сущности и совокупности существенных признаков к заявляемому техническому решению, является устройство для сбора мусора с использованием транспортного средства, взятое автором в качестве прототипа (См. патент Российськой Федерации jYo2088722, МПК Е01Н 1/05, 1995г.). The closest in technical essence and essential features to the claimed technical solution is a device for collecting garbage using a vehicle, taken by the author as a prototype (See Russian Federation patent jYo2088722, IPC Е01Н 1/05, 1995).
Устройство содержит рабочий орган и корпус-накопитель. Рабочий орган в виде щетки движется в кожухе. В устройстве размещен гибкий направляющий трубопровод, связаный с выполненным в кожухе желобом и гибким конвейером. Конвейер имеет вид витой цилиндрической спирали, расположенной в желобе и трубопроводе, вращающейся с помощью привода, в качестве которого может
использоваться гидромотор. Желоб служит накопителем для сбора мусора, в меру накопления которого происходит его перемещение вдоль оси спирали вращающегося конвейера. The device contains a working body and the housing. The working body in the form of a brush moves in the casing. The device has a flexible guide pipe connected to a chute and a flexible conveyor made in the casing. The conveyor has the form of a twisted cylindrical helix, located in the chute and the pipeline, rotated by means of a drive, which can used motor. The chute serves as a collector for garbage collection, to the extent of accumulation of which it moves along the axis of the spiral of the rotating conveyor.
