This article will be interesting to everyone who has a large amount of wood waste, or to those who harvest wood for the winter. The author of the channel "Make it Extreme" made a powerful chopper of branches, scraps of boards and the like. The unit easily turns this into a small sliver and sawdust.
After such processing, the raw materials can be used, for example, for the manufacture of fuel briquettes.
By the way, the grinder can be removed and used for its intended purpose in a matter of seconds. And this is important, because sometimes, in the manufacture of various devices based on it, it can even be disassembled. So this homemade product can be safely called the nozzle for the grinder.
To create this unit will require the following materials.
1. Steel sheet at least 6 mm thick.
2. Steel corner, or profile pipe.
3. Steel plate about 50 mm in diameter, for turning.
4. The grinder.
5. Chain for chainsaw.
6. Two flanges with bearings.
7. Paint spray.
8. Steel channel.
Instruments.
1. The lathe.
2. The welding machine.
3. Cutter for metal.
4. A grinder with conventional and stripping discs.
So, the author proceeds to manufacture.
First of all, it makes from one big chain about a dozen small ones. Each of which consists of 11 links.
Slices a piece of steel round with a circular saw.
And, holding a lathe in the chuck, it begins to grind the main part of the future crusher - the shaft.
Periodically water the workpiece coolant (cutting fluid).
He achieves that the chains fit tightly on the outer diameter of the workpiece.
On both sides grinds the shaft under the diameter of the bearing.
Bearing with flange tightly seated.
Turns the shaft over, prepares and cuts the threads for the adapter sleeve.
Thread ready, check connection with coupling.
Next, thread the clamping ring.
And grinds the ring itself.
Here is a shaft turned out.
Proceeds to its assembly. Screws on the clamping ring.
Then flanges with bearings.
Adapter sleeve.
And trying on a grinder.
The undercarriage is ready.
Now the author needs to make dividing rings, for this he grinds the pipe so that the chain snaps tightly. But it rested not with “teeth”, but with links.
The diameter is adjusted, you can cut the rings. Their thickness is such that the two chain knives do not touch each other.
Now the author can collect the cutting part of the shaft. Puts two rings on him.
Then a chain and one ring.
Repeats until it reaches the desired amount.
The last one to wear another wide ring, probably he had to adjust to fit.
And twists the clamping ring, squeezing all the elements together.
So, the chopper's heart is ready.
The next step is the manufacture of the frame. To begin with, from the channel, the author makes racks for the shaft.
It cuts the channel with an angle cutter.
By installing a metal bit on the drilling machine, it makes landing holes for the flanges.
On the same machine, drill holes for bolts.
Assembles a rack, fixes the flange with bolts using a wrench.
Racks are ready.
Inserts the shaft into the bearings, fixes the adapter sleeve.
Starts to assemble the frame. Welds the lower, then the upper corners to the channel.
As the base will use a steel sheet, installs a frame with a shaft on it.
Boil all the connections.
From the steel sheet makes the back wall for the feed tray. Clamps it in a vice and bends in several stages, in the lower part it is necessary to get a bend. It is needed so that the branches and sticks are better pressed to the cutting part.
Sets the wall in its place, its bend is clearly visible.
Welds on the back and front walls.
Then and lateral, the last wall presses with a clamp.
Boils all the seams.
So, the finish line. the construction is ready, the surfaces are cleaned. The author, unfortunately, did not show the moment how he made the mount for the grinder and the outlet.
Paints an aerosol can crusher.
The paint on the grinder has dried out, it remains to install the grinder.
Go to the test!
Tearing branches and small pieces of boards into chips, everything is fine!
Probably, in terms of improving the quality of the products obtained, or rather, obtaining a finer fraction, it is necessary to slightly modify the feed tray. Namely, make a notch on the bend of the back wall, or weld the spikes. This will not allow the saw to stretch the whole branches, namely to cut with knives.
Thanks to the author for the next, non-standard idea of using a grinder!
Observe safety precautions, do not throw scrap into the crusher ...
Good ideas to all!
