Brass Nozzle Sprayer

To blanket spray an open space or a drain, a bigger nozzle is required.  Brass nozzle for garden hose seems to be the best candidate.   

First, the nozzle is fitted into a rubber hose, of which is fitted into a 20mm polypipe.  The polypipe is finally fitted into a 30mm reinforced PVC pipe.   To hold the pipes together, a rubber strip from used tube is used to strapped the hose combination.

Lorry Loaded Ongrizinal Mechanized Herbicide Sprayer

Water pump is made for transferring water for watering plants – an essential practice especially for newly planted grass/plants, or during draught seasons  –  thus, a life-giving equipment.

Yet, amidst recent labour draught, such a life-giving equipment was re-assigned as a killing machine – mechanized herbicide sprayer.

First order of the ‘re-assignment’ exercise is to connect the pump’s outlet pipe to a cannibalized knapsack nozzle.   This is the most important step in the whole exercise.  Failure to connect the knapsack nozzle means non-available of spray pattern and desirable water droplets, thus the operation deemed a no-go.

First, the knapsack nozzle is connected to a 15mm diameter high pressure hose, tightened by a rubber strip.  Rubber strip seems primitive, yet its an effective and cheap way to secure pipe connections.  

Then, the 15mm hose is connected to a 32mm polypipe, and then again connected to a 40mm high pressure hose.  A rigid polypipe is used because when tightened with rubber strips, it won’t flattened and block the water flow.  Both end of the 32mm polypipe is secure with open-cut rubber hose to allow better grip between 15mm pipe and 40mm pipes.

The herbicide is mixed in 200L drums on a lorry.  A 3-man team is required when operating the sprayer : one monitoring the water and pump on the lorry, another to control the pipe on the ground, and the third one to handle the nozzle.

For spraying along road shoulders, the workers should be walking in front of the lorry, to allow better view of the lorry driver of the pace of spraying.   

The pump should not be used for watering, for fear of herbicide contamination.

Ongrizinal Lorry Low-Loader

1-tonne tipper lorry is a very useful machine for a urban landscaper like myself, working within a township.  It is easy to maneuver, cheap to maintain and very fuel economic too.   Yet, it still has limitation.

I hope it have a detachable trailer.  The trailer should not be too high from ground level, light yet durable, and can easily fit into lorry’s back carriage ( to carry to other sites ).

But, in reality, it don’t have a trailer.  Can’t even find one in the market!  So, I improvised.

First, I put 2 holes on one end of a 4’ x 8’ x 12mm plywood, 

then pass a rope through the holes. 

The plywood is place on ground and cow grass is unloaded onto it, 

from supplier’s 10-tonne tipper lorry.  

If the trailer is too high from the ground, 

unloading from 10-tonne tipper lorry would be a hassle, 

maybe even impossible.

Previously, the grass was unloaded on ground,  

and workers had to manually uploaded them onto 1-tonne lorry, 

to send to designated planting areas.  

The double-handling was a waste of time and energy.

Then the rope is then secured to the rear of 1-tonne lorry.

As the lorry pull the plywood, 

workers unload the grass on designated areas.   

It is a bit hard to pull due to the friction and the weight of the grass.

The plywood will surely damaged after the task. 

If only the plywood is attached to a metal frame with wheels.

A whole-day task completed in 2 hours !
