Martin Engineering M3660-07/09 1 MARTIN BULL DAWG Belt Cleaner

Introduction

General The MARTIN BULL DAWG Belt Cleaner is a dual-purpose cleaner. Itcan function as a pre-cleaner or a secondary cleaner. Traditionally, a pre-

cleaner is located on the discharge pulley and one or more secondary cleaners

are located after the belt leaves the pulley. The MARTIN BULL DAWG

can be located on the face of the pulley or after the tangent point.

The MARTIN BULL DAWG Belt Cleaner Blades have independent

suspension and are uniquely free to move in an infinite number of axes,

including a linear axis of motion. The blades have aggressive (positive rake)

peeling-angled tungsten carbide tips, which increase efficiency, while

reducing the required cleaning pressure.

IMPORTANTThe MARTIN BULL DAWG Belt Cleaner with

MARTIN SHOCK BLOK Shock Absorber can be used

with mechanical fasteners, provided these are in good

condition and installed using best practices, such as leadingedges which are flush with the belt cover, and bolts and nuts

which are ground flush with the plates.

CAUTION!The MARTIN BULL DAWG Belt Cleaner assemblies with

springs should NOT be used on belts with mechanical

fasteners. They are intended to be used only on Vulcanized

Belts. When used on belts with mechanical fasteners, damage

may occur to both the belt and the cleaner assembly. The

cleaner should NOT be used on a belt that contains gouges,

holes, or other belt imperfections, as the cleaner may causefurther damage to the belt.

Installationswithout chutework

These procedures were written for equipment that is being installed on

enclosed pulley chute work. If the pulley is not enclosed, the equipment

should be installed using the best available field resources and methods to

ensure that the critical dimensions are followed for proper installation.

The MARTIN Hanger Mount Assembly can be used for installations without

chute work. See Part Numbers for a list of mounts and part numbers.

Safety All safety rules defined in the above documents and all owner/employer safetyrules must be strictly followed when working on the belt cleaner.

DANGER!Do not touch or go near the conveyor belt or conveyor

accessories when the belt is running. Your body or clothingcan get caught and you can be pulled into the conveyor,

resulting in severe injury or death.

DANGER!Before installing, servicing, or adjusting the belt cleaner, turn

off and lock out/tag out all energy sources to the conveyor and

conveyor accessories according to ANSI standards. Failure to

do so could result in serious injury or death.

DANGER!If this equipment will be installed in an enclosed area, test the

gas level or dust content before using a cutting torch or

welding. Using a torch or welding in an area with gas or dust

may cause an explosion resulting in serious injury or death.

WARNING!

Before using a cutting torch or welding the chute wall, cover

the conveyor belt with a fire retardant cover. Failure to do so

can allow the belt to catch fire.

WARNING!Remove all tools from the installation area and conveyor belt

before turning on the conveyor. Failure to do so can cause

serious injury to personnel or damage to the belt and

conveyor.

WARNING!Mainframe with blade can be heavy and may require two

people to lift. Attempting to lift the belt cleaner without

assistance could result in injury.

Introduction

Before Installing Belt Cleaner

IMPORTANTThe delivery service is responsible for damage occurring in

transit. Martin Engineering CANNOT enter claims for

damages. Contact your transportation agent for moreinformation.

1. Inspect shipping container for damage. Report damage to delivery service

immediately and fill out delivery services claim form. Keep any damaged

goods subject to examination.

2. Remove belt cleaner assembly from shipping container.

3. If anything is missing contact Martin Engineering or a representative.

WARNING!Before installing equipment, turn off and lock out/ tag out all

energy sources to the conveyor and conveyor accessories

according to ANSI standards. Failure to do so could result in

serious injury or death.

4. Turn off and lock out/tag out energy source according to ANSI standards

(see References).

DANGER!If this equipment will be installed in an enclosed area, test the

gas level or dust content before using a cutting torch or

welding. Using a torch or welding in an area with gas or dust

may cause an explosion resulting in serious injury or death.

5. If using a cutting torch or welding, test atmosphere for gas level or dustcontent. Cover conveyor belt with fire retardant cover.

IMPORTANTCenter the belt cleaner blades to clean an area narrower than

the conveyor belt width. This allows for side-to-side

movement of the belt and prevents damage to the belt edge.

NOTEThe chute wall that the tensioner will be located on is referred

to as the operator side. The other side of the chute isreferred to as the far side. (If installing dual tensioners, side

that is most accessible is operator side.)

6. Determine which side of chute is easiest to access. Locate the tensioner

on the most accessible chute wall.

Installing Belt Cleaner

IMPORTANTRead entire section before beginning work.

To install the belt cleaner, follow the procedures corresponding to the

following steps:

1. Locate belt cleaner on chute walls.

2. Install mount brackets and mainframe assembly (inside or outside chute

walls).

3. Install cover door (if using).

IMPORTANTFor belts with mechanical fasteners, Martin Engineering

recommends mounting cleaner off the head pulley. Ensure thecleaner is placed within 2 to 4 inches (50 to 100 mm) of head

pulley or hold-down roll for most effective cleaning.

WARNING!The MARTIN BULL DAWG Belt Cleaner should not be

located on the pulley face where blade contact point is more

than 30 before the vertical centerline. The MARTIN BULL

DAWG Belt Cleaner must never be located where belt

slopes upwards, over the cleaner, as blades could become

locked in place.

Figure 2.

Locating beltcleaner on chutewalls

1. Determine whether belt cleaner will be mounted onto outside chute walls

or inside chute walls.

NOTEMartin Engineering recommends installing MARTIN BULL

DAWG Cleaner outside the chute.2. Determine where you want blades to contact belt and mark point on

outside or inside chute wall, as applicable. Do not mount in path of

material flow. Make sure belt is adequately supported at blade-to-belt

contact point. Install belt support if necessary.

3. After choosing blade-to-belt contact point, mark point level with belt

surface (Point A).

30 Max.

I

t l l t i


10/28


4. See Figure 3 and perform the following:

a. If Point A is on head pulley, find head pulley center and mark line

(Line A) from head pulley center through Point A and extend line

minimum of 12 in. (300 mm) below Point A. If Point A is behind

head pulley, mark line (Line A) through Point A and perpendicular

(90) to the belt. Extend Line A 12 in. (300 mm) below Point A.

b. Mark another line (Line B) 4 in. (100 mm) on the upstream side

(towards the discharge) and parallel to Line A. Extend Line B at least

12 in. (300 mm) below the belt. Line B sets centerline of the jackscrew

of the clamp assembly.

IMPORTANTLine B must be on upstream side of Line A. Clamps and

mainframe assembly must be on downstream side of threaded

jackscrew. This is to avoid rotational overturning forces being

applied to clamps and jackscrews. Clamps are designed to tilt

mainframe 10 back when installed as described in theseinstructions.

c. Draw Line C perpendicular (90) from Point A on Line A to a point on

Line B. Line C is tangent to belt at Point A.

Figure 3.

d. Hold clamp assembly centered over Line B with center of mount plate

approximately 2 in. (50 mm) above Line C and mark mounting holes.

IMPORTANTClamp assemblies are pre-assembled for top mounting. The

adjustable sliding clamps have two supporting posts angled at

10 from perpendicular. When clamp assemblies are bottom-

mounted the sliding clamps must be removed from threaded

jackscrews and turned over so supporting posts are angled

towards pillow blocks. This will set the mainframe tilted back10. Double jack nuts with spring lock washer between them

must be replaced on jackscrew to lift sliding clamp and

prevent cleaner from losing belt contact.

5. When mounting to outside of chute, it will be necessary to provide access

windows for cleaner assembly to pass through. Window should be 6 in.

wide by 12 in. high (150 mm by 300 mm), centered on Line A and

extending below Line C. Mark two parallel lines 3 in. (75 mm) to each

side of Line A. On these two lines, mark top corners of window

approximately 3 in. (75 mm) below the marked hole locations (for top

mount position). Mark bottom corners 12 in. (300 mm) below top corners.

For bottom mount position, mark bottom corner of windowapproximately 3 in. (75 mm) above the marked hole locations. Mark top

corners 12 in. (300 mm) above lower.

Installing cleaneron inside chute

1. Follow same instruction for mounting cleaner on outside of chute wall,

except ensure clamp does not interfere with head pulley. Also, there is no

need to cut an access window.

NOTEWhen installing cleaner inside chute walls, mainframe tubemust be cut at both ends. Measure from center of pulley to

each chute wall. Mark each measurement, minus 1/2 in.

(13 mm) for clearance, from center of mainframe, then cut off

excess. Remove burrs and sharp edges.

Figure 7.

CAUTION!When mounting MARTIN BULL DAWG Belt Cleaner on

inside chute walls, mainframe must be secured with safety

cables. Without cables, belt cleaner could break loose and

cause damage to conveyor.

2. Install MARTIN BULL DAWG Cable Kit (P/N 34883) or equivalent

onto belt cleaner mainframe as follows:

a. Drill 1/2-in. (13-mm) hole (A) 3/4 in. (19 mm) from each end of

mainframe blade cavity plate.

b. Weld D-rings (C) onto chutework parallel to Clamp Mounts.

c. Install shackles (D) through holes in ends of mainframe.

IMPORTANTFollow these steps carefully to ensure proper tensioning.

Adjusting and

setting operatingtension

1. Turn the single, upper jack nut towards belt to allow room to adjust

cleaner height.2. Raise mainframe by hand, working evenly on both sides, to avoid binding.

Support slide clamp at each lifting stage with the upper of double jack

nuts. Do this until blades are approximately 1/8 in. (3 mm) from belt all

the way across.

3. Lift one side by hand until you feel it lightly contact belt. Support this

position with jack nut. Repeat this on other side. Blades should now be in

even, light contact with belt, across full width.

4. Raise jack nuts on each side by two full turns towards belt. Cleaner is now

correctly tensioned for normal conditions. If belt is worn hollow and

some blades are not making contact or if uneven cleaning is observed

during test run, one additional turn can be applied. This extra turn shouldnot be applied with belts traveling faster than 500 fpm (2.5 m/s) with

mechanical fasteners.

5. Lock down upper jack nut on both sides.

6. Tighten bottom jack nut on both sides.

7. Tighten bolt on clamp gate.

8. Check that all fasteners are now fully tight.

WARNING!Threaded parts of clamp assembly may have been coated with

anti-seize compound, which may be harmful through skincontact or ingestion. Wash your hands thoroughly after

handling these components.

Installing CoverDoor

1. Install and tension MARTIN BULL DAWG Belt Cleaner.

2. Push cover door onto MARTIN BULL DAWG Mainframe so bushing

fits around square tubing.
