Agricultural machinery – special machine production which today is given the highest priority because of the quality of their Assembly depends largely on the degree of processing areas, the rate of harvest, or perform planting. This whole set of operations in the end determines the future crop of farmers and ranchers. In this article harvester combine “don”. All of its features and technicalities will be discussed below.

General information

"don-1500B", specifications of which will not remain without our attention, is the optimized machine, which began to go off the Assembly line in the already distant from Soviet times. In the Soviet era, this powerful unit was the most popular in the country among the techniques for harvesting grain and other crops. For two decades «Rostsel'mash» (Rostov) has produced this brand of processor, while in 2006, began the era of the new combines that Vector and Acros.

Purpose

Combine the ‘don-1500B” is designed and used for collecting a variety of crops both directly and separately by combining, in the fields, the plains, the slope of which does not exceed the eight degrees. In some cases the machine may be operated to work with small-seeded crops, cereals and legumes. The use of the combine is allowed in all climatic zones, which is very convenient from a practical point of view, because such a wide spectrum of applications puts the car in the best light to potential buyers.

Distinctive traits

The salient features of which are harvester «don-1500B" are:

• A drum.
• The straw Walkers, are equipped with five keys.
• Heavy-duty Engine.
• The large bin for collection and temporary storage of grain.
• Schema threshing – classic markets, respectively.
• The Linear dimensions of the crank of the crankshaft is increased, as well as reduced speed of rotation.
• Sieve «don-1500B” is greater compared with similar parts of other machines.
• The pulley on the drum has got a wider range of speeds.
• Drive header was the reverse.
• Special decks allowed to eliminate stiction during operation with wet grain.

It is Also worth to indicate the presence of a driving axle with high strength and fast unloading mechanism. In addition, if necessary the machine can be equipped with stacker differently, hood, chopper.

Finger eccentric mechanism has a very well thought out mount, which is deeply recessed in a high strength steel body of the screw. This design feature eliminates the winding of anything during careful harvest. Himself the cutting apparatus can be operated in two versions: with fingers open and fingers closed.

Advantages

“don-1500B" of the technical characteristics of which make it one of the leaders in the market of agricultural machinery, has the following undeniable positive qualities:

• On its wheels has tires with low pressure and high grousers. This allows the unit not to take even in very humid and sticky earth during a long operation.
• The Motor of the combine harvester are very economical.
• An Impressive diameter of threshing drum allows you to process even wet ears are rather large.
• To protect the threshing mechanism from clogging a special system of lowering the so-called concave and its speed is reset.
• Is it possible to mount the harvester in three sizes. The structure of this working body is so thought out that allows you to copy all the existing irregularities of the soil. Replacement harvester is fast and without any difficulties for staff.
• Ergonomically designed, spacious driver's cab, which is well protected against noise, moisture and dust. It also installed air conditioning to maintain a normal microclimate and ensure the comfort of the worker.
• Increased the size of the grain tank. This feature allows less fit vehicles for transportation of crop to the harvester, which also leads to fuel savings during the harvest.
• The Harvester is specially designed for the domestic agricultural sector and thus often much more effective on the job, in comparison with foreign analogues. Spare parts for agricultural equipment of this type also have relatively low cost.
• Simplicity and ease of repair. Many operators are very often self-repaired the machine in the field without resorting to outside help.

Negative traits

Fortunately, the shortcomings of the machine quite a bit, or rather, they are just two:

• Due to the close location of the power unit to the operator's cab on the driver enters the flow of hot air.
• Foreign harvesters still have a higher level of reliability and comfort and also have a greater number of different auxiliary functions, which affects their price.

Brakesystem

“don-1500B" (technical characteristics of the car bring it to the leaders of sales in the domestic market) is equipped with a special brake for Parking, which is controlled by a lever with a button that closes the lock-dog. In order to stop the combine, you will need to pull the lever up to third (or fourth) click. Disabling of the brake occurs by performing the movement of arm upward with a parallel push of a button.

In addition, the machine is equipped with hydraulic brakes of the disc type that are installed on each wheel separately. Brakes are mounted on the side gears and are driven through the pedals, the height of which is regulated by the brake cylinder fork. An important caveat: separate braking should not be used on hard roads, because it is developed to work on wet, soft ground.

Hydraulic system

The Hydraulic drive of the harvester is represented by three subsystems:

• Actuator to control the chassis.
• Wheel Drive steering.
• Hydraulic operating mechanisms which include a minimum number of pipelines, and also has valves of spool type operated as a hydraulically and mechanically. The system controls the rotation of the auger, reel, header, with chopper, turns the threshing drum and clears the airway.

Steering control system

The harvester is connected to a hydraulic system, and because its rotation does not require application of considerable physical effort from the operator. The steering wheel can be readjusted directly under the growth driver. This applies to a collet. Using a special pedal can also be adjusted and the tilt steering in the range of 5–30 degrees.

Navigation mechanism

The Control axle of the harvester takes place hydraulically, and this, in turn, allows you to adjust the movement speed is continuously variable irrespective of the speed range. This fact provides good maneuverability car. The hydraulic motor is mounted on a shaft of the transaxle (it is mechanical, three-way, features 4 modes while moving forward and one for backward motion).

The Slave bridge is also driven by hydraulics. The grip of the harvester is made dry, single plate with diaphragm spring type. Car is equipped with a deep tread that provides excellent traction and self-cleaning.

A Few words about the header

The Header consists of:

• Cutting unit.
• Balancing Mechanism.
• The Drive mechanism.
• The Divisor.
• Reel (is attached using four Soskov).
• Screw.

The Front part of the harvester is equipped with a shoes for the exact copy of the underlying surface (soil). Transportation of the harvester carried on a special truck.

As for cutting, it can be both open and dual fingers. The reel is equipped with a pair of eccentrics and driven by two synchronously moving hydraulic cylinders. The inclination of the tines is adjustable in automatic mode. Increased and the size of the screw, the value of which is 590 millimeters.

Electrical system

A System of electric equipment of the machine is a one-wire and operates at a DC voltage of 24 Volts. Also available is a alternator and built-in rectifier. A characteristic feature of the wiring of the unit is the presence of automatic controlling system for all process and technical status of main units and parts, including the chopper «don-1500B” and his speed, and augers, solomonashvili, engine, oil temperature in the hydraulic system, water.
