Digga tips - best practice to increase the life of your wearparts.

-
The cutting teeth & pilot on any auger are wear parts and you can increase the life of them with the help of Digga's best practice tips.

The wear life of a tooth or pilot is undefinable. They will be affected by how often they are used, how they are looked after and the ground conditions they are being used in.

For example, in non-fracturable ground where the rock is reduced to a powder; the powder is likely to get caught in and around the cutting head and, acting like a sand paper, will wear away both the pocket and the tooth. In hard ground conditions such as rock over heating within the hole can cause the ground to glaze over. The heat will polish the rock making it harder and have a greater influence on the wear of your cutting heads.

To assist with peak performance and longevity of the wear parts there are a few procedures that can be carried out that will help prolong the life of wear parts and increase drilling efficiency.

To help increase the life of your wear parts, you can:
Grinding, cutting and drilling rock will generate heat due to the friction between the two substances. It is good practice to periodically remove the auger from the hole and also add water.
We recommend every 4 to 5 minutes lifting the auger out of the hole to allow cooler air into the hole and the hot air to exit.
The use of water has a dual effect, not only assisting in cooling the cutting face, but by binding the dry loose material together for easier spoil removal.
  • Ensure the pick tooth is rotating freely in the pocket. 
If there is a lot of dirt or spoil around the pick tooth, it will eventually stop rotating. As you check the tooth pick heads and clear off spoil, also check that it can rotate freely. If your pick tooth has been rotating as it should, it will look like it has been in a pencil sharpener. If there are any flat spots then this is an indication that the tooth has been jammed and is not rotating. A good method to free up the teeth is to hit the tooth or pocket with a hard plastic or copper hammer. If this does not free up the tooth then you may need to remove the tooth, clear the debris and refit it. Check this out for more info.
Ensuring a straight hole is drilled by adjusting the arc of the excavator boom when drilling into the ground ensures there is no side load put on the auger which can bend the auger and cause damage to the head, pilot and teeth.

If you over use your wear parts it will ultimately slow you down and potentially cause damage to your auger, auger flights and auger drive. Keep your wear parts clean and in-check and keep working efficiently!

How to Operate A Digga Bucket Broom

-
Image
Having trouble operating your Digga bucket broom? There are a few tips and tricks when it comes to brush adjustment & height, rotation direction and the broom emptying procedure. We've summarised them for you below. Direction of travel and brush rotation Always sweep at a high enough brush speed and low ground speed to effectively discharge the material being swept. Brush height adjustment Remove the handle pin, twist the handle, and replace the pin. Re-adjust the axle to the correct height using both handle adjusters. Return handles to their original position. Correct Brush Height Set the height of the brush so the bottom of the brush is approximately 30mm lower than the bucket cutting edge. The brush must be level. Emptying Procedure When the bucket requires emptying, stop the rotation of the brush, lift your loader arms and crowd the bucket forward so the Bucket Broom hood swings away from the bucket. Examples of Damaged Bucket...

How to Replace DR Auger Rock Picks (Dedicated Rock Augers)

-
Image
Rotating rock picks, are the auger teeth used on our Digga dedicated rock augers (DR) for drilling from soft rock to hard fracturable rock. Here are some things you can observe to determine whether the rock picks are worn: The teeth need to rotate while drilling to maintain an efficient cutting tip. The tungsten tip and tooth should be evenly pointed. Poorly maintained teeth reduce cutting efficiency and wear out faster costing time and money. We recommend you replace worn teeth immediately! Tip: the outside teeth (C) will wear the fastest as they are travelling the greatest distance so will need replacing more often. Try swapping the outer tooth for an inner tooth to keep the wear even. Always use your best teeth on the outside pockets. Here are some examples or rotating rock picks in various states of wear. Tooth A has not been rotating in the pocket and as a result the tooth is uneven and will cut poorly. We recommend changing this tooth. You may also notice if the tungsten tip has...
