Silage baler is mainly composed of aluminum roller mechanism and traction part, feeding mechanism, main transmission mechanism, winding strapping mechanism, safety shield mechanism and so on. Silage round bales in the strapping machine before the addition of a group of conveyor belt device, the material evenly and quickly into the baling room, with bundling fast, the material is not blocked, the degree of compactness, etc., to avoid the other baler bundled grass Bundle density is small, easy to mold after the phenomenon of sticky, bundled corn straw density, easy to cover silage. At the same time on the other dry, fresh grass can also be bundled, animal husbandry is one of the necessary equipment. The quality of the nutrient value, the aroma aroma, the content of crude protein, the content of crude fiber, the high digestibility and the palatability of the algae, High feed rates, livestock utilization rate of up to 100%. No loss of mildew loss, loss of fluid and feed loss are greatly reduced. Traditional silage losses of up to 20% -30%. Do not pollute the environment. Due to good sealing performance, no liquid outflow phenomenon. Suitable packaging, small size, high density, easy to transport and commercialization. Long shelf life. Compressive seal is good, not affected by season, sun, rain and groundwater level, can be stacked in the open air 2-3 years.
