roll baler with winding

When they talk aboutroll baler with winding, many people immediately think about film. But if you dig deeper, in practice, the whole point is not in the winding itself, but in what happens before and after it. A common mistake is to think that the main thing is to wind the film tighter. In fact, if the density of the bale is initially low or the humidity of the haylage is not the same, even if you wind it ten layers, the feed in the center may spoil. I myself saw how, at a farm near Tver, rolls, seemingly perfectly packaged, had pockets of mold inside. The reason turned out to be trivial - we were hasty with the selection, the mass was uneven in moisture. This is something that is rarely written about in brochures.

From theory to field: where the real difficulties lie

Take, for example, setting the pressure of the bale chamber. The instructions are clear: for hay - one mode, for haylage - another. But there is rarely an ideal, homogeneous mass on the field. There are areas with coarser vegetation, and somewhere the grass has died. If you chase high density on “heavy” ones. areas, the belts or chain drive may be overloaded. And if you loosen it, the roll will turn out loose and will not be stored well. What is needed here is not so much instructions as an instinct that is developed through hours of work. Sometimes it seems that it is better to underpress a little, but ensure uniformity.

It is in such nuances that the difference between simple equipment and a reliable unit is visible. We once tested several models, including paying attention to balers fromHulunbuir Machinery Manufacturing Company ?Jiujia?. I went to their websitecn-fascar.ru, looked at the specifications. The company description states that it is a modern integrated enterprise with a full cycle from development to service. What is important is that their devices often have a hydraulic density adjustment system, which automatically adjusts to the load. This is not a panacea, but it seriously helps the operator, especially during long cleaning periods when attention becomes dull.

Another point that many people miss is field preparation. What difference does it seem? But if the windrow is uneven or too wide, the pick-up will not pick up the crop evenly. As a result, the roll is formed with voids or different densities along its length. Then wrap it anyway you can, problems with silage are almost guaranteed. You have to either slow down or go through the field twice, which kills all the time savings. This is where a baler with a smart feed system that can compensate for windrow unevenness comes in handy.

Winding system: the details that make all the difference

Actually,roll winding. Now almost everyone has switched to mesh or film. Film, especially for haylage, is a must have. But even here there are pitfalls. Not only the tensile strength of the film is important, but also its elasticity. At low temperatures at dawn, cheap film becomes brittle and may break already at the winding stage or during transportation. Also, the number of layers is critical. Five layers is standard. But if the roll is very dense or has high humidity, six is ​​better. Conversely, for dry hay sometimes four are enough so as not to waste too much. This is a matter of economics, but to make a mistake means losing food.

The film feeding mechanism must also be debugged. It happened that the clamping mechanism did not properly fix the beginning of the film, and it slipped when starting. As a result, the first turns were weak, the roll was poorly protected in this place. Or, conversely, the tension mechanism is too rigid and tears the film in the process. Modern models, for example, the same "Jiujia", often have sensor tension control and a break sensor. Trifle? On paper - yes. But when you are alone in the field and you need to pack hundreds of rolls in a day, such a “trifle”? saves from downtime and material damage.

And after winding - ejection, ejection of the roll. It would seem that what is so difficult here? But if the ejection occurs abruptly, with an impact on the ground, not only the film, but also the structure of the roll can be damaged, especially if it has not yet “settled”. A good baler places the bale gently, almost rolling it. This preserves the integrity of the packaging. I remember at the demonstration of one of the models I noticed the smooth operation of the ejector belts. The manager then explained that this was due to the overall balance of the car and the hydraulic settings. It’s details like these that reveal a well-thought-out design.

Integration into the farm: more than just a machine

Buyinground baler, in essence, you are buying a link in the technological chain. You need to think about how you will transport these rolls and where to store them. A roll weighing about 800-900 kg is not a toy. A suitable forklift and trailer are required. And if the storage facility is far from the fields, then logistics costs can eat up all the benefits of high-quality packaging. Sometimes it makes more sense to set up temporary storage points right at the edge of the field, but this requires additional organization and security.

This is where an integrated approach that declaresHulunbuir company ?Jiujia?. On their websitecn-fascar.ruit is clear that they position themselves as an enterprise for agriculture and livestock farming in general. This suggests that they can offer not just a baler, but look at the whole picture: perhaps they can advise on transportation equipment, or give recommendations on organizing storage based on the characteristics of their presses. For a large farm, such integration is a serious plus.

Another practical aspect is maintenance. Knives, belts, bearings in winding units - all these are consumables. It is important that you have access to them without dancing with a tambourine. It is better when the covers are removed using several bolts, rather than twenty. And that spare parts are available. The story of a broken plastic film guide roller causing a machine to sit idle for two weeks in the middle of harvesting is a mechanic's nightmare. Therefore, when choosing equipment, I always look not only at the price tag of the machine, but also at the availability of the service network and spare parts.

Economics of the process: everything needs to be counted

The investment in a wrapping baler is significant. Therefore, every ruble must be justified. The simplest calculation is the cost of packaging one roll (film/mesh) plus depreciation and fuels and lubricants. But there are also hidden factors. For example, loss of feed during storage. If, thanks to high-quality dense packaging and proper wrapping, losses are reduced from 15% to 5%, this is a huge saving on the scale of even an average herd. Or the opportunity to prepare food at the optimal phase, without waiting for the “ideal” one. weather, because you are confident in the conservation system.

Sometimes it seems that you can save money by buying a simpler model without the bells and whistles. But over a long distance, over five to seven years of operation, the difference in productivity and safety of feed can cover the initial difference in price many times over. Especially if we are talking about a farm where the food supply is the basis. This is where the same research and development that manufacturers like Jiujia write about are important. It’s not just to collect iron, but to calculate how it will behave in the real conditions of different regions, with different humidity and crops.

In the endroll baler with windingis a tool. And like any instrument, it should fit in your hand. His choice is a compromise between power, reliability, maintenance complexity and, of course, price. There is no ideal model for everyone. For some, mobility and maneuverability in small fields are more important, for others - productivity and endurance 24/7. The main thing is to understand that you are buying not just a “roll and wrap” function, but a key link in the technology for preserving the nutritional value of your food. And milk yield and weight gain in the next season directly depend on this choice. Everything else is details, albeit very important ones.
