The basic plan of the windmill is not identical. It shows that it is derived from Aes Sistan, which is slightly changed in dispersed areas of Nehbandan city. Therefore, all of them have the same plan, and somewhat similar. Lower bloody stains It is made of two floors, the upper space of which is a larger area where the parts of the masonry are connected and recorded.
This space is surrounded by three walls, the main walls and the walls are located vertically to the north of the south, and the sidewall connected to the eastern wall extends to the half-wall to the west and the open area is the arrival of 120 days of winds, The wall is curved in the direction of wind blowing. The edges of the wall in the south are steep so that people can access large parts of the pavement through it.
Due to the winds of 100 days and access to wind energy in the production of wheat flour, the technique of building webs in the Nehbandan area was prevalent at least a thousand years ago (since the report of Massoudi). However, hundreds of days of winds caused severe erosion And the gradual destruction of these structures. Consequently, the present foundations in the Nehbandan area are more common in recent centuries, especially from late Safavid to Qajar. In general, according to some documented reports in the Qajar period (such as Zulfaqar Kermani and Yeet), it can be said that these structures have been constructed or refurbished during the Qajar period. On the other hand, the pottery found on the site also implies The presence of windmills is at least in the Safavid period to Qajar.
The rocks are generally circular in diameter from 10 to 15 centimeters, among which a hole with a diameter of 15 cm or more is embedded in the entrance of a piece of beam and flap.
Each Ace of the house is of the same size in terms of diameter, which is fixed to the bottom of the stone, and therefore a stone with a larger diameter of stone ruby. On the upper surface of the rock, also the zigzag branches are specially designed for it. Has been created.
The other functional parts of the hermetic wind turbine (Toure), which is a metal similar to a swallows tail of 36 to 45 cm in length, causing a rotation of the upper stone. The thread that is placed between the tufa using yarn and fat or Cotton or fat is produced, and in fact its function is in the bearings of this piece of Asia from one side to (Toure) and on the other side to the bottom of the bottom of the beam and helps to rotate the stone fast. The teardrop is a piece of It was indirectly connected to the floor, and this connection was obtained with a piece of thick wood called (vault) (padding) by placing a part of the wood (vault) up and down These stones help slowly and slowly accelerate, but the piece with which the wheat slips from its storage to the foot is a wooden device called the rock on Asia. He throws the wheat into the bottleneck through the tank.
The ground floor of the AES House also includes a limited space in which to store the flour, the place where the wheat is stacked, the staircase leading to the upper chamber, the platform, and so on. The roof of the ground floor uses a clay with a cavernous covering and a semicircular hollow. The ground floor is converted to the location of the arms and blades when the house is closed. The lower bloody lining is formed in general with clay and stone.
The structure of this windmill is this, a vertical column is placed and the two walls are restrained in the lateral directions, in the space open to the south and two-thirds of the space is closed to the north. On the top of the column and in the middle of it is a cross beam, the column at the bottom of the millstone crosses and places where it is embedded. The upper millstone is connected by wedges to the column and rotated along with it, while the bottom of the rock stays constant without movement, the column's height reaches 6 meters, and above the blades by Straw and horizontal beams are attached to it, from the chamber that is open to the north, the wind strikes the blades and circles them.
Fixed ball mill also includes a 4.5 to 5 meter long wooden ramp which is usually used for pine trunks with a planar. Without this piece, the other components can not be connected to each other. The axle is the same as the stationary axle It uses two small pieces of wood and two long wooden knives to connect to the syringe and, due to its better position in time, uses fat-free animals to reduce their agglomeration, they are connected in a series of axis of the ring of iron rings to leave It prevents corrosion of the wood, there are smooth rectangular gaps on the surface of the beam, The bases, which are parallel to each other, hold the blades in a vertical position to remove the 120-day wind and transfer this force to the arms and then to the axis of the arm. The arms of the arms, the nails of the arms, They come in the middle of the holes, which are specially positioned for the type of their use in the beam. In the lower bloody windmill, all blades consist of leaves and leaves of the palm tree and narrow straw pieces that are tied together. And in the form of bundles to open and solid wood.
