BUNKERS AND SILOS EPUB


Material is fed into a vibrating hopper and is pushed into the blower using a spinning spiral auger. There is commonly a water connection on the blower to add moisture to the plant matter being blown into the silo. The blower may be driven by an electric motor but it is more common to use a spare tractor instead.

A large slow-moving conveyor chain underneath the silage in the forage wagon moves the pile towards the front, where rows of rotating teeth break up the pile and drop it onto bunkers and silos high-speed transverse conveyor that pours the silage out the side of bunkers and silos wagon into the blower hopper.

Bag filling[ edit ] Silo bags are filled using a traveling sled driven from the PTO of a tractor left in neutral and which is gradually pushed forward as the bag is filled. The steering of the tractor controls the direction of bag placement as it fills, but bags are normally laid in a straight line.

The bag is loaded using the same forage harvesting methods as the tower, but the forage wagon must be moved progressively forward with the bag loader. The loader uses an array of rotating cam-shaped spiraled teeth associated with a large comb -shaped tines to push forage into the bag. The forage is pushed in through a large opening, and as the teeth rotate back out, they pass between the comb tines.

The cam-shaped auger teeth essentially wipe the forage off using the steel tines, keeping the forage in the bag. Before filling begins, the entire bag is placed onto the loader as a bunched-up tube folded back on itself in many layers to form a thick pile of plastic.

Because the plastic is minimally elastic, the loader mechanism filling chute is slightly smaller than the final size of the bag, to accommodate this stack of plastic around the mouth of the loader.

The plastic slowly unfurls itself around the edges of the loader as the tube is filled. The contents of the silo bag are under pressure as it is filled, with the pressure controlled by a bunkers and silos brake shoe pressure regulator, holding back two large winch drums on either side of the loader.

Cables from the drum extend to the rear of the bag where a large mesh basket holds the rear end of the bag shut. To prevent molding and to assure an airtight seal during fermentation, the ends of the silo bag tube are gathered, folded, and tied shut to prevent oxygen from entering the bag.

Removal of the bag loader can be hazardous to bystanders since the pressure must be released and the rear end allowed to collapse onto the ground.

Due to the limited space, the door hinge frame is also the ladder. On the right is the unloader power cable and yellow silage drop tube with removable access doors for insertion of the silage drop spout.

The tube is illuminated by light entering through fiberglass panels every 20ft along the outer steel shroud. Electric winch for raising and lowering silo unloader. A silo unloader specifically refers to a special cylindrical rotating forage pickup device used inside a single tower silo.

The main operating component of the bunkers and silos unloader is suspended in the silo from a steel cable on a pulley that is mounted in the top-center of the roof of the silo.

The vertical positioning of the unloader is controlled by an electric winch on the exterior of the silo. For the summer filling of a tower silo, the unloader is winched as high as bunkers and silos to the top of the silo and put into a parking position.

The silo is filled with a silo blowerwhich is literally a very large fan that blows a large volume of pressurized air up a inch tube on the side of the silo. A small amount of water is introduced into the air stream during filling to help lubricate the bunkers and silos tube.

A small adjustable nozzle at the top, controlled by a handle at the base of the silo directs the silage to fall into the silo on the near, middle, or far side, to facilitate evenly layered loading.

Once completely filled, the top of the exposed silage pile is covered with a large heavy sheet of silo plastic which seals out oxygen and permits the entire pile to begin to ferment in the autumn. In the winter when animals must be kept indoors, the silo plastic is removed, the unloader is lowered down onto the top of the silage pile, and a hinged door is opened on the side of the silo to permit the silage to be blown out.

There is an array of bunkers and silos access doors arranged vertically up the side of the silo, with an unloading tube next to the doors that has a series of removable covers down the side of the tube.
