Abstract

A demining machine utilises a roller (30-39; 72; 83, 84) that rolls on the ground. The roller has annular rows of teeth (58, 80) that penetrates the earth as the roller moves. There is a vibrator (60) inside the roller. The vibrations improve the penetration into the ground and the tips of the teeth transmit the vibrations to the ground so that the vibrations detonate mines deeper down in the earth. The root systems of the vegetation are left comparatively undisturbed.

Description

4507 sas Q II. Varje boggie 15-19 bar tva valsar 30-39. Valsarna 32-37 ar inte visade kompletta som valsarna 30,3l,38.39. 4507 sas Q II. Each bogie 15-19 carried two rollers 30-39. Rollers 32-37 are not shown complete as rollers 30.3l, 38.39.

Ramens tvarbalk ll ar lagrad i tva armar 45,46 för att vara svangbar kring en axel III och dessa armar är lagrade, för att vara svängbara kring en axel IV, i tva fästen 47 pà ett fordon visat som ett larvbandburet fordon exempelvis en ombyggd stridsvagn 48. Fordonet 48 visas endast i Figur 1. I stället för att armarna 45,46 ar individuellt infasta mot fordonet kan de vara förenade och gemensamt infasta med en universalled, vilket underlättar styrning. Detta föredragna utförande ar emellertid inte visat. För att ytterligare göra det lättare att styra kan man fästa ramen ll-14 i dess bakersta del och ha hydraulcylindrar eller andra organ för att lyfta armen eller armarna 45,46. I stället för att ha en stel ram ll-14 kan man ha en midjestyrd ram, vilket också ger förbättrad styrförmaga. Dessa och andra olika sätt att förbättra styrförmagan kan användas var för sig eller användas i olika kombinationer.The crossbeam of the frame is mounted in two arms 45,46 to be pivotable about an axis III and these arms are mounted, to be pivotable about an axis IV, in two brackets 47 on a vehicle shown as a crawler vehicle, for example a converted tank 48. The vehicle 48 is shown only in Figure 1. Instead of the arms 45,46 being individually attached to the vehicle, they can be joined and jointly attached to a universal joint, which facilitates steering. However, this preferred embodiment is not shown. To further make it easier to steer, one can attach the frame ll-14 to its rear part and have hydraulic cylinders or other means for lifting the arm or arms 45,46. Instead of having a rigid frame ll-14, you can have a waist-guided frame, which also provides improved steering ability. These and other different ways to improve control can be used individually or used in different combinations.

En vals visas schematiskt pà Figur 3. Den har en trumma 50 pa vilken ett antal plàtskivor 51 och mellanlagg i form av ringar 49 ar staplade. De spanns ihop av ej visade anordningar. Skivorna 51 är stjarnformade sa att de far ett antal spetsar 58 som syns pa Figur 1. Skivorna kan exempelvis vara l cm tjocka och mellanlaggen kan exempelvis vara 5-10 cm tjocka. Trumman 50 har en axel 53 som är lagrad med lager 52 i boggien som betecknas 54 och får representera alla boggierna 15-19. Genom axeln 53 löper en axel 55, som ar lagrad med lager 56,57. En excentervikt 60 ar fast pà axelns 55 ena ande och en kilrepsskiva 59 ar fast pà axelns 55 andra ande. En fastskruvad plàt 67 skyddar excentervikten från jord. Excentervikterna 60 i varje vals 30-39 drivs av en gemensam motor 61 som ar monterad pà armen 45 och har en kilrepsskiva 62 inuti armen 45 och driver en axel 63 inuti tvarbalken ll. Axeln 63 har kilrepsskivor och med .E21 ,__ I [Ü repet ansmi sioner 1 balkarna 12-14 och i boggierna 507 385 roteras alla excentervikterna 60 av motorn 61. I Figur 1 syns kilrepet 65 i boggien 16 och kilrepet 66 i boggien 18.A roller is shown schematically in Figure 3. It has a drum 50 on which a number of plate discs 51 and intermediate layers in the form of rings 49 are stacked. They were clamped together by devices not shown. The discs 51 are star-shaped so that they have a number of tips 58 which can be seen in Figure 1. The discs may, for example, be 1 cm thick and the intermediate layers may, for example, be 5-10 cm thick. The drum 50 has a shaft 53 which is mounted with bearings 52 in the bogie designated 54 and is allowed to represent all the bogies 15-19. A shaft 55 runs through the shaft 53, which is mounted with bearings 56.57. An eccentric weight 60 is fixed to one end of the shaft 55 and a V-belt pulley 59 is fixed to the other end of the shaft 55. A screwed-on plate 67 protects the eccentric weight from the ground. The eccentric weights 60 in each roller 30-39 are driven by a common motor 61 which is mounted on the arm 45 and has a V-belt pulley 62 inside the arm 45 and drives a shaft 63 inside the cross member 11. The shaft 63 has wedge rope pulleys and with .E21, __ I [Ü rope anchors 1 in the beams 12-14 and in the bogies 507 385 all the eccentric weights 60 are rotated by the motor 61. Figure 1 shows the wedge rope 65 in the bogie 16 and the wedge rope 66 in the bogie 18.

Trummorna i en boggie har sina verktyg, dvs skivornas spetsar 58, ordnade i rader och ena valsens rader av verktyg sträcker sig in mellan andra radens verktyg. Detta medför att valsarna rensar varandra. Utan rensning skulle stenar kunna fastna mellan en skivas spetsar och försämra funktionen. Säkerheten för att ett mina ska detonera ökas av att man har tva valsar i tandem och den ökar ytterligare när de tva valsarna är monterade pà en boggie. Om den första valsen skulle fa dålig nedträngning så kommer nästa vals med sina skivor som inte gar i samma spar. Vibrationen gör att rensningen underlättas. Vibrationen ger i sig detonation och detonationsgraden ökar av att vibrationerna eller slagen fortplantar sig fràn de nedträngande spetsarna 58.The drums of a bogie have their tools, i.e. the tips 58 of the discs, arranged in rows and the rows of tools of one roller extend between the tools of the second row. This means that the rollers clean each other. Without cleaning, stones could get stuck between the tips of a disc and impair its function. The safety of a mine detonating is increased by having two rollers in tandem and it is further increased when the two rollers are mounted on a bogie. If the first roller should have poor penetration, the next roller will come with its discs that do not go in the same groove. The vibration makes cleaning easier. The vibration in itself causes detonation and the degree of detonation increases as the vibrations or blows propagate from the penetrating tips 58.

Vibreringen ger saledes spetsarna en slagverkan som detonerar minor på avsevärt större djup än spetsarnas inträngningsdjup. Dessutom underlättas spetsarnas nedträngning av vibreringen och maskinen behöver inte göras så tung.The vibration thus gives the tips an impact effect that detonates mines at considerably greater depths than the penetration depth of the tips. In addition, the penetration of the tips is facilitated by the vibration and the machine does not have to be made so heavy.

Marken lämnas relativt orörd efter maskinen. Den far smala slitsar anordnade i ett mönster. I vissa fall kan dessa slitsar vara till fördel eftersom de luftar jorden och förbättrar nedträngning av vatten. Vegetationens rötter lämnas förhållandevis oskadda och risken för ökad jorderosion är inte sä stor.The ground is left relatively untouched after the machine. The father narrow slits arranged in a pattern. In some cases, these slits can be beneficial because they aerate the soil and improve water penetration. The roots of the vegetation are left relatively undamaged and the risk of increased soil erosion is not so great.

Skivorna och deras spetsar 58 skadas inte av trampminor och vanligen inte heller av större minor. När större stridvagnsminor detonerar kan skivorna skadas. Om skivorna skadas så att trummorna i en boggie inte längre roterar byter man ut den boggien vilket normalt kan göras pà mindre än 30 minuter. Man renoverar sedan de skadade trummorna genom att byta ut de skadade skivorna. Eftersom skivorna och ihopspända mot varandra gar ett sådant utbyte snabbt och 507 sss Å/ verktygen, dvs skivorna, är dessutom enkla och billiga. Tack vare att drivningen av vibrationsanordningarna sker med kilrep ökar inte montering och demontering av drivningen för vibrationsanordningarna tidsàtgàngen nämnvärt.The discs and their tips 58 are not damaged by treadmills and usually not by larger mines. When larger tank mines detonate, the discs can be damaged. If the discs are damaged so that the drums in a bogie no longer rotate, that bogie is replaced, which can normally be done in less than 30 minutes. The damaged drums are then renovated by replacing the damaged discs. Since the discs and clamped together, such an exchange is fast and the 507 sss Å / tools, ie the discs, are also simple and inexpensive. Thanks to the fact that the vibration devices are driven with wedge ropes, the assembly and disassembly of the drive for the vibration devices does not significantly increase the time consumption.

Alternativt till tunna skivor och mellanläggsringar kan man använda kraftiga ringar pà vilka man monterar spetsar individuellt. Dessa spetsar kan da ha hàrdmetallinsatser.As an alternative to thin discs and shims, you can use strong rings on which you mount tips individually. These tips can then have carbide inserts.

Genom att man anvander ett antal likadana korta valsar eller hjul kan man bygga maskiner i olika storlek med samma element. För användning i en sandöken kan man bygga mycket stora maskier som skjuts fram av en stridsvagn. Man kan också bygga smala maskiner för terräng som inte tillater breda maskiner. Man kan exempelvis bygga en maskin med tva valsar bak och en mellanliggande vals fram och inte använda boggier. Dä kan man ocksa ha styrning pà den främre valsen eller ha en midjestyrning. Drivfordonet kan vara ett lättare fordon exempelvis ett dumperchassi eller en skogsmaskin. När man inte har valsar i tandem så att de rensar varandra, kan man istället ha fasta rensverktyg som sticker in mellan skivorna.By using a number of similar short rollers or wheels, you can build machines of different sizes with the same elements. For use in a sand desert, you can build very large masks that are pushed forward by a tank. You can also build narrow machines for terrain that does not allow wide machines. For example, you can build a machine with two rollers at the back and an intermediate roller at the front and not use bogies. Then you can also have control on the front roller or have a waist control. The drive vehicle can be a lighter vehicle, for example a dumper chassis or a forestry machine. When you do not have rollers in tandem so that they clean each other, you can instead have fixed cleaning tools that protrude between the discs.
