The Rice Harvest #3

Here is a closer view of the working harvester.

 

On the front is a complex, two metres wide mechanism. It has a revolving rake that lifts the crop, and presents it to the gang of scissors...the scissors cut the seeds heads off the plants along with some of the straw...the severed seed heads are then moved to the elevator by a large revolving drum screw...the elevator lifts the seed heads up to the thresher, which separates seeds from the seed heads and straw. The mechanism takes its power from the main diesel engine, and utilises it with the aid of a bewildering combination of chains, belts, rotating shafts  and hydraulic rams.

 

A key role of the driver is to constantly tune the height of the rake and the scissors, at the same time as steering the machine and watching out for potentially disastrous tree stumps or other obstructions...all these adjustments are made with two joysticks. Na's brother and nephew have become quite adept at driving this machine.

 

On one side is a platform on which one or two people can operate the bagging mechanism...typically bags are made from hemp,  have 4 bushell capacity, and weigh 100kg when filled.

hard work to bring in the rice harvest Ray... they look like they are doing a great job ....petersmile
Ray: This year the "team" has functioned well...last year there was a bit of friction...

They are good operators, Peter.
Great photos to illustrate your explanation! I love the family teamwork!
Ray: It is a close family. Elizabeth...Na's Dad lives with us, as does her Sister and her Sister's 14 years old Daughter...Na's Brother lives in the next village but visits us about twice each day to help himself to a coffee break...Na's Brother's Son stays in our house 2 or 3 nights each week...etc...
i can imagine that the operation although may be tricky at first, gets easy to a consistent operator. the several belt and chain drives are probably going to require some maintenance attention for a healthy lifespan of the harvester, Ray. i like both shots.
Ray: The machine rides on tracks rather than wheels, Ayush, and this makes it an unfamiliar vehicle for most people. The machine does require high levels of maintenance...about 30 minutes of cleaning and adjusting at the end of each day, plus at least 10 parts failures that required in-field corrective activities during the 5 week season.

Na's brother manages the business for me, and he has become a very capable technician, and has even manufactured replacement parts on occasions.
I especially like seeing the curved bars that "hold" the men on the platform while the rice is sacked.
Ray: Yes...me too, Ginnie. ..spring-loaded, curved bars that easily pull into place and provide an extremely simple but effective mechanism for preventing the workers from falling off their platform.

I see the machine is equipped to carry three workers so that no time is wasted in stopping to remove the bag a and load the next one?
Ray: In a heavy crop, Lisl, 2 baggers are kept reasonably busy as they also sew the filled bags shut.

What an amazing life you lead..
Ray: Life is good, Chris...I think you have heard this from me before!

Farming, cycling, reading/writing, photography, travelling with friends, and just being with Na fill the days rather nicely.

It looks a great machine Ray, and I expect they are also capable of small repairs.
Ray: It is a good machine, Chad, and has performed for us for the past 9 years.

Impressionnantes ces machines , grande aide surement pour ces travailleurs , merci pour les explications Ray
Bonne journée
Ray: C'est une petite usine sur des pistes en caoutchouc de locomotives, Claudine, et son design est ingénieux!
Dur travail, malgré la chaleur, ils sont obligés de se protéger le visage de la poussière
Ray: Oui ... le travail est assez dur. et les conditions sont extrêmes, Martine.

That is quite an interesting series. I see a lot of dust flying around and see all, but the one closing the bag, all covered up, is that because of the nasty dust of also insects that might attack??
Ray: The covering is for protection from dust, insects and the sun, Astrid...it can be quite challenging to spend a day out in these conditions.

I'm sure all exposed drive chains and belts would have been covered by guard in the UK. Is the machine owned by co-operative so that the costs and benefits are shared?
Ray: The machine has metal covers for all the chains, belts and shafts, Alan, but my team have found they can work better if the covers are removed so they can constantly observe what is happening on this complex unit.

The machine is owned by me...the business pays the running and maintenance costs...we charge a per rai [a Thai area measure which is something like 1/4 of a hectare] fee to cover costs, including salaries, and get a small profit which we share with Na's Brother who manages the business.
A skilled job by the sound of it
Ray: Certainly driving is complex, Bill, but we have two good and careful drivers in the team.

The driver is well protected against the dust and bits flying around. All very interesting.
Ray: He needs all that protection, Louis, as he is crouched directly over all the action...and so there is dust, straw and insects constantly bombarding him.
It is a fascinating machine, so many cogs and gears and bits and pieces.
Ray: It is extremely complex, Brian, and needs a lot of TLC.
A typical combine but small. It also reminds me of a blueberry harvester.
Ray: Yes...quite like its bigger brothers, Mary, but they usually run on wheels rather than tracks.
Thank you for the explanation...
Ray: You are welcome, Larry. I find it all very interesting but sometimes wonder if that curiosity is shared by others.
Lifting those bags will need some muscular development!
Ray: I usually seek assistance these days if I am man-handling these big bags, Tom.
