Celem zmniejszenia nadmierngo pylenia wystepujacego podczas pracy szczotek talerzowych, zamiatarki te wyposazone sa ponadto w urzadzenie spryskujace jezdnie, któ¬ rego dysze usytuowane sa przed bocznymi szczot¬ kami talerzowymi oraz w wentylator, z którego wlotem polaczony jest posrednio, poprzez komore zbiornika zmiotek, tunel szczotki walcowej oraz bezposrednio kanal ssawkdi usytuowanej miedzy szczotkami talerzowymi. Stosowanie natrysku i ssawki zmniejsza wprawdzie pylenie szczotek, jednakze spryskiwanie jezdni nie zawsze jest za¬ lecane lub mozliwe a ponadto zwilzone woda drob¬ ne zanieczyszczenia sa znacznie ciezsze i trudniej je usunac z powierzchni jezdni.Istota wynalaziku polega na wyposazeniu za¬ miatarki w oslony,, otaczajace czesciowo szczotki -talerzowe, które tworza komory pylowe w strefie pylenia, przy czym kazda z komór pylowych po¬ siada wylot do tunelu szczotki walcowej usytuowa¬ ny w obrebie strefy tworzenia sie i/lub dzialania strugi powietrza wyrzucanego przez segmenty 10 szczotki walcowej z tunelu do komory nad zbior¬ nikiem zmiotek.Rozwiazanie wedlug wynalazku, wyposazone w oslony szczotek talerzowych, posiada ograniczona, strefe pytania, przy czym skutecznosc odsysania, pylu z przestrzeni zamknietej jaka jest komora pylowa jest znacznie lepsza niz w znanych roz¬ wiazaniach zawierajacych jedynie boczne fartuchy gumowe. Ponadto na skutek dzialania strugi po¬ wietrza wyrzucanego z tunelu szczotki walcowej,, oprócz podcisnienia panujacego w tunelu podczas pracy wentylatora, powstaje w strefie, gdzie znaj¬ duje sie wylot komory pylowej dodatkowe podcis¬ nienie zwiekszajace intensywnosc odsysania zapylo¬ nego powietrza z tej komory i zasysania do niej powietrza otaczajacego nieoslonieta czesc szczotki,. w wyniku czego zamiatarka pracuje niemal bez¬ pylowe.Przedmiot wynalazku przedstawiony jest w przy¬ kladzie wykonania; na rysunku, na którym fig. 1 ukazuje zamiatarke w przekroju poprzecznym,, a fig. 2 — w przekroju wzdluz linii A-(A zazna¬ czonej na fdg. i.Szczotka walcowa 1 umieszczona jest w tunelu 2, z którego powietrze zasysane jest wentylatorem 3, wytwarzajacym podcisnienie rzedu 2 mm H^O^ poprzez komore filtrów 4 usytuowana nad zbiorni¬ kiem zmiotek 5, Z prawej strony zamiatarki 6„ przed szczotka walcowa 1, zabudowana jest w oslonie 7 boczna szczotka talerzowa, przy czym 121 214121 814 "tylna scianke oslony 7 stanowi przednia blacha tunelu 2 szczotki walcowej 1.

PLThe patent description has been published: 31.12JL984 121214 Int. Cl.3 E01H 1 / OS Inventors: Zdzislaw Wrzesniewski, Leonard Fracala. The holder of the patent: Research and Development Center of Urban Treatment, Lodz (Poland) Sweeper The subject of the invention is a sweeper used to remove contaminants from Hardened surfaces, especially road surfaces, with a disc brush for sweeping the curb places. Sweepers with a roller brush are known, in front of the ktf-ra are two disc brushes protruding partially beyond the side rubber aprons. In order to reduce excessive dusting occurring during the operation of disc brushes, these sweepers are also equipped with a road spraying device, the nozzles of which are located in front of the side disc brushes, and a fan, the inlet of which is connected indirectly, through the chamber of the sweepings tank, the brush tunnel. cylindrical shaft and directly the suction channel located between the disc brushes. The use of a spray and a squeegee reduces the dusting of the brushes, however, spraying the road is not always recommended or possible, and moreover, the moistened fine dirt is much heavier and more difficult to remove from the road surface. The invention consists in equipping the sweeper with covers, , partially surrounding the disc brushes which form dust chambers in the dust zone, each dust chamber having an outlet to the roller brush tunnel located within the zone of formation and / or action of the air stream ejected by the segments 10 of the roller brush with tunnel to the chamber above the litter tank. The solution according to the invention, provided with shields of disc brushes, has a limited, question zone, and the efficiency of suction of dust from a closed space, which is a dust chamber, is much better than in known solutions containing only side rubber aprons. Moreover, due to the action of the air stream ejected from the tunnel of the cylindrical brush, apart from the negative pressure prevailing in the tunnel during the fan operation, an additional negative pressure is created in the zone where the dust chamber outlet is located, increasing the intensity of sucking the dusty air from this chamber. and draw air into it, surrounding the bare part of the brush. as a result, the sweeper works almost dust-free. 1 shows the sweeper in cross section, and FIG. 2 shows a section along the line A- (A marked on fdg. i. The roller brush 1 is placed in the tunnel 2 from which air is sucked) a fan 3 generating a vacuum of 2 mm H 2 O 4 through the filter chamber 4 located above the sweepings container 5, on the right side of the sweeper 6 "in front of the roller brush 1, the side disc brush is built in the cover 7, where 121 214 121 814" the rear wall of the cover 7 is the front sheet of the tunnel 2 of the cylindrical broom 1. The dust chamber 9 which forms the cover 7 surrounding the disk-brush 8 has an outlet 10 to the tunnel 2 of the cylindrical broom 1, located within the action of the air stream 11 ejected from the tunnel 2. into the filter chamber 4 through the segments 12 of the brush 1. [During the operation of the sweeper 6, when the action of the air stream 11 creates an additional negative pressure of 3 mm HjP within its zone, the disc brush 8 is sucked in and fed into the (dust chamber). lowa 9, small impurities are entrained into the tunnel 2 of the cylindrical brush 1 at high speed as a result of the total negative pressure of 5 mm H ^ O of the donor in the tunnel 2 at the outlet 10 and the dust chamber 9, to then destroy the velocity in the zone of reduced vacuum 10 13 of pressure and settle on filters 13, or band into a hopper 5.
