Simple Calibration APP to help speed reel in harvester, the methodology used was 20 seconds from Embrapa and index calculation based on the reel.

Windlass
The function of the reel is leading the plants against the cutter bar and soon after cut the lead to Ias snail feeding. The reel should move smoothly culture and uniformity, avoiding excessive friction or hits that could cause thrashing of spikes. The regulations of a reel are as follows:

POSITION reel
Horizontal: a pattern of crop to normal the **** of the reel should be shifted about 15 to 20 cm in front of the cutter bar as shown in Figure 1. When plants are very tall advance the reel. On the other hand, when the crop plants has too low, the reel is retracted to near the feed worm, as shown in Figure 2. Vertical crops in normal condition, the tip of the tooth reel should be about 5cm culture ajustadana abaixoda lowest pod, as shown in Figure 3. When there lodged plants, the reel should be moved well forward of the cutter bar, tending to the crop is always performed in the direction of the slope.

Rotational Speed

Receive part of the plant and the pods, starting the operation trail. The rotation speed of the drum is concave and the opening of which will determine the greater or lesser action track. Thus, the higher the speed of the cylinder, the lower should be the distance between the cylinder and concave. At harvest, grain quality monitor that is going to the bulk tank is watchword. Properly regulating the opening of the concave and the rotation of the cylinder, the lower are the chances of damage by mechanical losses occur in grãode soja.Lembrar that the front opening between the cylinder and concave to be about five millimeters larger than the portion of behind. It is also important to note the parallels between the cylinder and concave.
ADJUSTMENTS CYLINDER
Opening between the cylinder and concave
The gap between the cylinder and concave affects the quality and quantity of action trilhadora grain is separated from the chaff concave. The opening between the cylinder and concave must be larger at the entrance than at the exit. That's because the bulk of the material stands on the trailhead. This concentration is decreasing as the grains are falling through the concave. The setting of this opening is done mechanically, electric or hydraulic, depending on the model harvester. For sejauniforme track, it is necessary that the gap between the cylinder and concave sejaigualem both ends of the cylinder, as shown in Figure 5. When the track is difficult, one can reduce the gap between the cylinder and concave, to make thinner the layer of straw, causing most of the pods to contact the co-action cylinder and there is better track. As one increases the spacing between the cylinder and concave, track occurs more at the rear of the concave and there is no time for grains to be separated. As a result, they fall on the straw walker, overloading them.

Cylinder Speed
Cylinder speed areta the quality of grain and pinched elevaa amount of broken grains. Under the conditions of the crop, must establish the tangential velocity of the cylinder, expressed in m / s, which is calculated as follows: veloddode cylinder tongenciol = (2? / 60) x roiodocilindro (m) = m / I. Knowing the diameter of the cylinder, the cylinder rotation can be calculated by: Drum rpm x 60 = Vt / 2? x Rc, where: Vt = tangential velocity of the cylinder, Rc = radius of the cylinder.
