The utility model discloses a round bale silage baler, round bales to provide a compact, high, low feed round bales of silage losses balers. Including walking chassis, transmission, hydraulic system, swing hopper, fixed hopper, electric control system, bundling mechanism and configured on the bundling mechanism packet network device. The baling mechanism drive shaft, tensioning shaft, driven shaft and four support shafts are supported on both sides of the wall mounted in compression chambers, two bilateral synchronous chain passes around the drive shaft, the tension axis, four support shaft and a driven shaft sprocket, so that both sides are two chains forming a closed circle arc, which is supported on the inner ring is located in the compression chamber side walls of the circular slide, pressure roller are cloth mounted on both sides of two endless chains. The utility model is suitable for high moisture silage chopped tied round bales jobs. Silage can reduce the loss of nutrients, improve feed utilization. Generally making hay nutrient loss of 20% -30%, sometimes as much as 40% or more, while only after silage nutrient loss of 3% -10%, in particular, to effectively preserve vitamins. In addition, silage, also can eliminate a lot of material to carry parasites (such as corn borer, borer) and harmful bacteria. It is measured in the same unit area of ??arable land, the nutritional value of whole plant corn silage than grain corn produced by the middle of plus dry corn stalks higher nutritional value of 30% to 50%. ? Silage baling machine for envelope Qufu Wan Teng Machinery Co., Ltd. based on customer needs to develop a new type of silage products by bundling machine, coated two parts. ? Farms dedicated silage baling machine capsule works: through the front of the machine to the fixed positions of artificial feeding, when large fixed bale warehouse and warehouse activities exposed to certain compactness, inert and active positions at the top of the roll on the left side of the signal uniformly rotating wheel, the operator clutch plates move winding handle, the machine starts reciprocating Rao rope tied around the rope a week, automatically cut off the rope, immediately opening release bundles, bales directly into the rotating capsule machines shelves, pull out the film by hand, start rotate button, rotating frame driven bale rotation, the operator should be synchronized quickly membrane pressure to bale, and with the bale rotation, then immediately let go, pasture film gradually step by step wrapped in a bale, the bale revolution since the rotation of the frame, when the envelope to the set of layers, the clutch automatically disengages stop rotating frame, the operator between the bale and transport membrane film frame to pasture cut off one end of the pasture film breaks overlap end face pressed into bales, with a good bale will move into a small envelope pushing the car, push it away neatly. Wan Teng brand silage baling machine coated recommend employing three people, a man feeding a person opening square bales and envelope, put a person to push it away. The machine compared with conventional machines, saving labor 60%, a bundle, every 24 seconds coated layer 2 / layer 3 packet 36 seconds / 48 seconds every 45 seconds 4-layer envelope, a bundle of efficiency increase of 21%, the efficiency of the envelope growth of 40%, a bundle weighing 40-75kg quality assurance: human factors within a year, due to product quality and machine parts need to be replaced, the company in addition to a free replacement, and bear accessories packaging, transportation costs for silage round baler realization of agricultural mechanization design and development of new products is driven by the tractor propelled strapping, bundling can be a fixed place, both can be used, suitable for field work; it is mainly used for forage, straw, wheat straw collecting and bundling in order to forage for transport and storage, in particular the various silage storage, production efficiency is essential machinery of animal husbandry and aquaculture
