Description

144093144093

Den foreliggende opfindelse angår en fiødemekaniems til indfødning af faste materialer, såsom eksempelvis halm eller træflis, i et tranaportrør med en fødeåbning i siden, hvilken mekanisme omfatter et mod og bort fra fødeåbningen i en samlebeholder bevægeligt stempel.The present invention relates to a feed mechanism for feeding solid materials, such as straw or wood chips, into a crane conveyor with a side feed opening, comprising a counter and away from the feed opening in a collector piston movable.

Pra beskrivelsen til tysk patent nr, 406,652 kendes en sådan mekanisme, hvor det nævnte fødestempel arbejder i et vinkelret på transportrøret stående føderør, som er forsynet med en tilføreelstragt. Pødestemplet er synkroniseret med et transports tempel, som fremfører materialet i transportrøret, på en sådan måde, at fødestemplet går frem, når transportstemplet går tilbage, og omvendt.From the specification of German Patent No. 406,652, such a mechanism is known in which said feed piston operates in a feeder tube perpendicular to the conveyor tube, which is provided with a feed hopper. The plunger piston is synchronized with a conveyor temple which feeds the material into the conveyor tube in such a way that the plunger protrudes as the conveyor piston goes back, and vice versa.

Når fødestemplet trækkes bort fra fødeåbningen, vil transportstemplet altså blive ført frem mod det netop tilførte materiale og trykke det gennem transportrøret bort fra fødeåbningen. Imidlertid er der herved stor risiko for, at noget af materialet trykkes tilbage i føderøret, og at materiale fastklemmes ved fødeåbningens kant. Dette medfører, at transportstemplet hæmmes i sin fremadgående bevægelse eller endog fastkiles på grund af det af føde- · åbningskanten fastholdte materiale.Thus, when the feed piston is pulled away from the feed opening, the conveying piston will be advanced toward the newly supplied material and push it through the transport tube away from the feed opening. However, there is thus a great risk that some of the material is pushed back into the feed tube and that material is clamped at the edge of the feed opening. This results in the conveyor piston being inhibited in its forward movement or even wedged due to the material held by the feed opening edge.

Ifølge den foreliggende opfindelse foreelås, at fødestemplet i den frie ende er udformet som eller bærer en tryksko (3), hvis mod transportrøret vendende flade er således udformet, at den i det væsentlige svarer til den i fødeåbningen manglende del af transportrørets væg.According to the present invention, it is proposed that the feed piston is formed at the free end as or carries a pressure shoe (3) whose surface facing the conveyor tube is so designed as to substantially correspond to the portion missing from the wall of the conveyor pipe.

Ved denne fødemekanisme trykkes fødeøtemplets tryksko ind i fødeåbningen og udfylder, medens transportstemplet føres frem, denne åBning på en sådan måde, at transportrørets væg i det væsentlige bliver glat på indersiden. Der er derfor ingen kant ved fødeåbningen, som kan gribe materiale, og der er ingen rieiko for, at materiale trykkes tilbage i samlebeholderen.In this feeding mechanism, the feed shoe pressure shoe is pressed into the feed opening and, while the conveyor piston is advanced, fills this opening in such a way that the wall of the conveyor tube is substantially smooth on the inside. Therefore, there is no edge at the feed opening which can grasp material, and there is no risk of material being pushed back into the collecting container.

Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, der skematisk viser et transportrør med en fødemekanisme ifølge opfindelsen.The invention will now be explained in more detail in connection with the drawing, which schematically shows a conveyor tube with a feeding mechanism according to the invention.

Det viste transportrør 1 har i siden en fødeåbning, 2 144093 gennem hvilken fast materiale, såsom eksempelvis halm, pap, træflis eller affald, indføres, I transportrøret 1 er anbragt et frem- og tilbagebevægeligt transportstempel 5, med hvilket det indførte materiale kan trykkes gennem røret, Pødeåbningen er omgivet af en samlebeholder 2 for det materiale, som skal indføres i røret 1, I samlebeholde-ren 2 er et fødestempel 4 bevægeligt mod og bort fra føde-åbningen i transportrøret 1, I den frie ende er fødestemplet udformet som eller bærer en tryksaks 3> hvis henimod transportrøret vendende flade i det væsentlige svarer til den i fødeåbningen manglende del af transportrørets 1 væg, Uår trykskoen derfor føres ind i fødeåbningen, udfyldes denne, således at transportrørets 1 væg bliver i det væsentlige glat på indersiden.The conveying tube 1 shown in the side has a feed opening, through which solid material, such as, for example, straw, cardboard, wood chips or waste is introduced. The tube opening The feeding opening is surrounded by a collecting container 2 for the material to be inserted into the tube 1. In the collecting container 2 a feed piston 4 is movable towards and away from the feed opening in the transport tube 1. carries a pressure shear 3 whose surface facing the conveyor tube substantially corresponds to the portion missing in the feed opening of the wall of the conveyor tube 1.

Pødestemplets 4 tryksko 3 forbliver i denne fødeåbningen lukkende og rørvæggens inderside udglattende stilling, medens transportstemplet 5 føres frem forbi åbningen. Der er derfor ingen risiko for, at materialepartikler fastklemmes mellem transportstemplet og fødeåbningens kant, hvilket ville hæmme eller endog hindre bevægelse af transportstemplet. Der er heller ingen risiko for, at materiale af transportstemplet 5 gennem fødeåbningen presses tilbage til samlebehol-deren 2.In this feed opening, the pressure shoe 3 of the piston 4 remains closed and the inside wall of the tube wall smoothing, while the conveying piston 5 is advanced past the opening. Therefore, there is no risk of material particles being trapped between the conveyor piston and the edge of the feed opening, which would inhibit or even hinder movement of the conveyor piston. Also, there is no risk of material of the conveyor piston 5 being pushed back into the container 2 through the feed opening.
