Title of the invention

Device for mounting a front-mounted device on a street sweeper.

Field of application of the invention

The invention relates to a device for rotating, raised, lowered and pivotally supporting a country for sweeping surfaces such as high shelves, winding dirt traps, areas under parked ITutzkraftwagen and other surfaces of public transport space as well as Werkge * used \ ^r orbaubesens on a street sweeper.

Characteristic of the known technical solutions

It is known round or plate broom by means of a

Parallelоgrammführuns ^а ^ street sweepers rotating, raised, lowered and swiveled to arrange. The arrangement is usually behind the front axle. Such disc brooms do not protrude far beyond the vehicle profile and are very narrow in their range of motion.

It is also known to arrange an additional disc brush as an attachment to the front of the vehicle. The attachment takes place at the front part of the vehicle frame by means of a mounting plate. The lowering is effected by means of an extension arm and a known four-bar boom arrangement attached to it. This pre-assembly counter is pivoted and locked by hand from the pivoted transport position into the working position outside the driver's cab.

After carrying out the work, the stem counter must be returned to the transport position by hand ·

The disadvantage of this device is that when selectively connecting the attachment during the sweeping the Kraftfahrer.jeweils forced to interrupt the sweeping · This creates a loss of time. In addition, due to the low possibility of evading the Vorbaubesens, too far projecting obstacles, the vehicle must be controlled in the other direction. As a result, a portion of the surface to be swept, for example chutes, can not be swept, which leads to a reduction in the sweeping quality. In addition, this represents a traffic obstruction »

Another disadvantage of this device is that the use of a non-height adjustable boom arm the possible height adjustment of the plate

broom is limited. Therefore, this device is only suitable for sweeping high ropes.

Another disadvantage is the attachment of the attachment. The attachment, or the removal of the Vorbaubesens is complicated and requires high changeover times,

Object of the invention

The aim of the invention is to provide a device for holding a Vorbaubesens on a street sweeper in such a way that all necessary for sweeping with the Vorbuaubesen turning, lifting, lowering and pivoting movements can be triggered by the operator of the sweeper during the sweeping from the cab and the Vorbaaubesen at the same time represents a quick-change accessory.

Explanation of the essence of the invention

The objects of the invention are achieved in that at a suitable for several accessories, known per se, mounting plate front of the sweeper a side projecting base frame is arranged on a storage a Dreigelenkträger is articulated via a bearing, which via a lever with a From the cab connected pneumatically or hydraulically actuated cylinder for the purpose of swiveling in and out of the front attachment

is. The Dreigelenkträger is further designed so that on the second pivot point, the storage of a Parallelogrammführung for the broom is pivotally mounted to allow evasion of Vorbaaubesens backwards when hitting obstacles. A working cylinder fastened to the three-jointed carrier is connected to a lever of the bearing of the parallelogram guide and thus acts as a spring, in order to independently bring the projection frame back into the working position after passing through an obstacle.

The lifting and lowering movement of the round broom, which is preferably coupled to the rotary movement of the round broom, which takes place directly via a hydraulic motor, preferably takes place electro-hydraulically or electropneumatically via a cylinder by separate circuit from the cab. Thus, it is possible in any required sweeping situation, the Vorbaaubesen as an additional device from the cab off or off. In order to achieve an optimum sweeping quality, the 7-nozzle nozzles required for dust binding and a working headlight required for night use are arranged on the front-mounted broom. The attachment of the stem as an attachment to the mounting plate by means of known quick-change device, e.g. Pin. All cables are routed to the basic unit via likewise known quick-release couplings, in order to ensure fast conversion of the basic unit.

Depending on the design of the base frame, it is possible to insert the front bogie right as well as left side ·

At a sweeper 1, the known mounting plate 2 suitable for several accessories is arranged. At this mounting plate 2 a base frame 4- is attached by means of plug 3. This base frame 4-is provided at the outer end of the right side of the vehicle with a bearing 5 to which a Dreigelenkträger б is articulated. The Dreigelenkträger 6 has two bearings 7 and 8, a holder 9 for attachment of a working cylinder 10 and a lever 11 which is connected via a cylinder 12 with the base frame 4 · for the purpose of swinging in and swinging the front jig on. On the bearing 7 of the three-jointed carrier б a bearing 13 -for the parallelogram guide 14 · of the round bale 15 is articulated by means of a bolt. The bearing 13 is provided with a lever 16 which is connected via the working cylinder 10 with the Dreigelenkträger б, whereby a deflection of the round broom 15 backwards when hitting obstacles and then again

pivoting back into the working position is achieved. The lifting and lowering movement of the round broom takes place from the cab by actuation of a switch, preferably electro-hydraulically or pneumo-hydraulically or electro-pneumatically, via a cylinder 17 and is associated with the rotary movement of the round broom 15 > Which is done directly via a hydraulic motor 18, coupled so that the broom 15 rotates when lowering, or, when lifting stands. A arranged in a known manner tension spring 19 regulates the required pressure of the bristles during sweeping. Through a water nozzle 21 located on a guard, the necessary dust binding of the garbage takes place. The switchable from the cab working light 22 allows effective use of Vorbaubesens even during the night. The formation of the working cylinder 10 is preferably carried out as a pneumatic cylinder, wherein the compressed air can be taken from the vehicle air system v / ground.
