Abstract

The drum chipper apparatus includes a frame (7), feed device (4, 5), a drum (2) equipped with blades and rotating devices, a counter-blade (8), a sieve (3) located beneath the drum (2), and a chip conveyor located beneath that. The sieve (3) includes two sieve layers (3.1, 3.2) on top of one another and devices (9) for moving them in relation to one another in order to adjust the opening size.

Description

15 20 25 30 35 509 046 2 I fig. 1 betecknas trumflishugganordningen schematiskt som 1 och den är monterad på lastbilen 11. Anläggningens grundelement är trumman 2, sållet 3, tryckrullen 5, fliskastaren 6 och chassit 7. Från flistranspor- inmatningsanordningen 4 tillsammans med tören hamnar flisen i en pneumatiskt transportör 8, vilken kas- tar flisen till en mellanlagringsplats. Anläggningen innefattar en lastapparat 12, med vilken veden matas till transportören 4. In Fig. 1, the drum chipping device is schematically referred to as 1 and it is mounted on the truck 11. The basic elements of the plant are the drum 2, the screen 3, the pressure roller 5, the chip thrower 6 and the chassis 7. From the chip transport feed device 4 together with The chip ends up in a pneumatic conveyor 8, which throws the chips to an intermediate storage location. The plant comprises a loading apparatus 12, with which the wood is fed to the conveyor 4.

Själva trumflishuggen är förutom sålluppbyggnaden av normalt slag. Inmatningsanordningen trycker veden genom tryck med tryckrullen 5 mot stålet 8 och trumman 2. Knivarna skär veden på känt sätt i mindre delar och dessa hamnar i sållet 3, vars uppbyggnad beskrivs närmare senare. Fliskastaren 6 under sållet är av centrifugaltyp och orsakar ett märkbart sug vid sållets undre yta, vilket främjar flisens genomgång. En hydraulmotor 6.2 driver fliskastarens rotor 6.1, vilken motors varvtal kan regleras. Fliskastaren innefattar en tryckgivare 15, på grundval av vars avgivna data det går att avgöra om en eventuell igen- sättning av huggen har skett. Detta möjliggör omedelbara och t.o.m. automatiska åtgärder. Sållets 3 undre del är i skydd av chassit 7 så väl som möjligt anslutet till fliskastaren, vilken åstadkommer ett sug i detta utrymme. På trumman finns service- luckan 10.In addition to the sieve structure, the actual drum chipping is of a normal kind. The feeding device presses the wood by pressing with the pressure roller 5 against the steel 8 and the drum 2. The knives cut the wood in known manner into smaller parts and these end up in the screen 3, the structure of which is described in more detail later. The chip thrower 6 under the screen is of the centrifugal type and causes a noticeable suction at the lower surface of the screen, which promotes the passage of the chips. A hydraulic motor 6.2 drives the chipper's rotor 6.1, which motor speed can be regulated. The chip thrower comprises a pressure sensor 15, on the basis of which the data provided can be determined whether a possible clogging of the cut has taken place. This allows immediate and t.o.m. automatic actions. The lower part of the sieve 3 is, under the protection of the chassis 7, as well as possible connected to the wood chipper, which produces a suction in this space. The drum has the service door 10.

Sållet 3 består av två delar 3.1 och 3.2, av vilka den övre är låst vid chassit 7 och det undre rör sig under detta, styrt av den hydrauliska manöverenheten 9. Mellan sållens delar finns glidorgan, vilka håller ihop delarna och dessa kan vid behov utbytas som en helhet. Sålldelarnas föredragna fria hålstorlek är 100 x 60 mm. I allmänhet är förhållandet mellan längd och bredd förmånligast i intervallet 1,3 - 2,0. Härvid kan två sålldelar monterade på varandra bilda hål av olika storlek inom ett brett intervall.The screen 3 consists of two parts 3.1 and 3.2, of which the upper is locked to the chassis 7 and the lower moves below it, controlled by the hydraulic control unit 9. Between the parts of the screen there are sliding members, which hold the parts together and these can be replaced if necessary. as a whole. The preferred free hole size of the sieve parts is 100 x 60 mm. In general, the ratio between length and width is most favorable in the range 1.3 - 2.0. In this case, two sieve parts mounted on each other can form holes of different sizes within a wide range.

Sållets delar är hälften så tjocka som ett normalt såll, varvid två skivartade sålldelar får plats i spåret 7.1 avsett för det ursprungliga vanliga sållet, vilket visas i fig. 3. Sålldelarnas skivor 3.1 och 3.2 är väsentligt likadana, dock är fastsätt- v-»afl 10 15 20 25 30 509 046 3 ningsanordningarna något olika. Mellan sållets delar finns glidorgan, vilka begränsar delarnas inbördes rörelse.The parts of the sieve are half as thick as a normal sieve, with two disc-like sieve parts being accommodated in the groove 7.1 intended for the original ordinary sieve, as shown in Fig. 3. The discs 3.1 and 3.2 of the sieve parts are substantially the same, but are fixed a fl 10 15 20 25 30 509 046 3 devices slightly different. Between the parts of the sieve there are sliding means, which limit the mutual movement of the parts.

Efter provdrift har sållstrukturen förbättrats enligt fig. 4.After test operation, the sieve structure has been improved according to Fig. 4.

För motsvarande delar används samma hänvisningsnummer som i fig. 3. Här har tillförts på den undre sålldelens 3.1 tvärslåar svetsade mellanlägg 3.10, vilka höjer dessa till väsentligen samma nivå som den övriga sållytan. Härvid förlorar man något i sållets maximistorlek, när den undre delen inte helt kan place- ras under den övre. Vid den största hålstorleken vrids mellan- läggen 3.10 intill den övre delens tvärslåar.For corresponding parts, the same reference number is used as in Fig. 3. Here, cross-welded spacers 3.10 have been added to the lower sieve part 3.1, which raise these to substantially the same level as the other sieve surface. In this case, you lose something in the maximum size of the sieve, when the lower part can not be completely placed under the upper one. For the largest hole size, rotate the spacers 3.10 next to the crossbars of the upper part.

En trumflishugganläggning enligt uppfinningen möjliggör an- passning av flisen till köparens kvalitetskrav. Den största fria hålstorleken (100 x 60 mm) möjliggör insamlande av grovkornig flis för energibruk. När sållet har justerats för mindre hål- storlek kan flishuggen producera finkornig flis som t.ex. passar för skruvtranport. Vid eventuella störningar kan de två såll- delarna vridas fram och tillbaka i förhållande till varandra och suget kan ökas under sållet. Härvid kan i de flesta fall igen- sättningar öppnas upp och dyrbar arbetstid förloras inte p.g.a. rensning av anläggningen.A drum chip installation according to the invention enables the chip to be adapted to the buyer's quality requirements. The largest free hole size (100 x 60 mm) enables the collection of coarse-grained chips for energy use. When the sieve has been adjusted for smaller hole sizes, the chipper can produce fine-grained chips such as suitable for screw transport. In the event of any disturbance, the two screen parts can be rotated back and forth in relation to each other and the suction can be increased under the screen. In this case, in most cases, blockages can be opened up and precious working time is not lost due to cleaning of the plant.

Fastän det är fördelaktigast att använda transportör av typ centrifugalfläkt enligt bilagda exempel, går det även att använda särskilt under fabriksförhållanden vanliga bandtrans- portörer under sållet.Although it is most advantageous to use a conveyor of the centrifugal fan type according to the attached examples, it is also possible to use, especially under factory conditions, ordinary belt conveyors under the screen.
