HOW DO SMALL RECTANGULAR BALERS WORK

Posted Aug 31, 2017 by Alan Xu

Today T&H packaging is going to introduce a type of baler that produces small rectangular (often called “square”) bales, which was once the most prevalent form of baler, but is less common today. By the way, the rectangular balers are known as Marilyn Monroe in agriculture, not only amazing at that time, but memorable all the time.

Firstly I’d like to introduce the use of rectangular baler, actually, it is primarily used on small acreages where large equipment is impractical, and also for the production of hay for small operations, particularly horse owners who may not have access to the specialized feeding machinery used for larger baled.

Then, it comes to bulk and weight. Considering about its consistence, each bale is about 15 in x 18 in x 40 in (40 x 45 x 100 cm). The bales are usually wrapped with two, but sometimes three, or more strands of knotted twine. The bales are light enough for one person to handle, about 45 to 60 pounds (20 to 27 kg).

Ok, now the most attractive part is coming, the operating part. To form the bale, the material to be baled, (which is often hay or straw) in the windrow is lifted by tines in the baler’s reel. This material is then packed into the bale chamber, which runs the length of one side of the baler (normally the right hand side when viewed from the front). A combination plunger and knife move back and forth in the front of this chamber, with the knife closing the door into the bale chamber as it moves backwards. The plunger and knife are attached to a heavy asymmetrical flywheel to provide extra force as they pack the bales. A measuring device—normally a spiked wheel that is turned by the emerging bales—measures the amount of material that is being compressed and, at the appropriate length it triggers the knotters that wrap the twine around the bale and tie it off. As the next bale is formed the tied one is driven out of the rear of the baling chamber onto the ground or onto a special wagon or collecting sled hooked to the rear of the baler. This process continues as long as there is material to be baled, and twine to tie it with. The bales emerge with four sides. The twine runs, in two parallel loops, around the wider sides. Of the two narrower sides, there is a cut side and a dull side, and when stacked for storage or transport the bales are normally positioned with the cut side facing outwards.

Actually, it’s a little hard to understand how small rectangular balers works. T&H packaging admired the inventor from the bottom of heart after a lot of observation and experiment. Finally, we jumped a conclusion that its useful for the small acreages, which is not so popular nowadays. But on the contrast, in some small hay productions, it can distinguish itself greatly.
