    A cooling system for the power plant of a self-propelled forage harvester or field chopper, generally located in the rear thereof, comprises an air chamber communicating with the atmosphere through laterally disposed filter screens and water-cooling radiators and through pairs of conical half-shells disposed point-symmetrically about ventilating fans integral with a unidirectionally rotatable shaft extending longitudinally in an opening in the top wall of the chamber. The shells, rigid with a support manually pivotable about the power-plant-driven shaft, normally direct air flow through the fans from the air chamber but may be rotated 180 DEG by a vehicle operator to temporarily reverse the air flow and pressurize the chamber, thus forcing air out through the radiators and filter screens, cleaning them of clogging debris collected during normal operation of the vehicle. Sealer strips provided around the openings in the air chamber for minimizing leakage.

    专利说明:

    The invention relates to an air-handling device, in a motor cooling system of a self-propelled agricultural machine, which allows for the cleaning of chillers by changing the direction of the flow of cooling air.
    In grain harvesting machines and machines for harvesting spike forage structures, the contamination of the cooling and filtering surfaces is a significant obstacle to the proper operation and temperature of the maximum permissible load of the drive engine.
    A device is known that reverses the direction of the flow of cooling air by turning the ventilation blades of an axial fan.
    However, it is very difficult to implement this when using a large number of axial fan discs.
    The principle of changing the direction of rotation of the disk of an axial fan is also known, for which a rotating system is required; drive, for example, allowing switching under load, reversing gear.
    Such transmission is very complex and expensive. Due to the large number of heavily loaded transfer elements, wear occurs reducing the reliability of operation of the entire machine.
    A device is known in which by alternating opening and closing of appropriately located valves of fans, the cooling air is drawn in and blown out through a lattice cover and a cooler, without changing the direction of rotation of the fan.
     This valve system is not reliable in operation and requires additional control elements.
    In addition, when the valves are controlled by means of transmission elements, wear comes and high operating power is consumed, which necessitates a hydraulic or pneumatic auxiliary device for servicing. A large amount of space is required to reverse the flow of cooling air by the valve system.

    constructions. Moreover, the problem of sealing is not resolved (relatively high air losses can occur /. Such a device has a limited area.
    The purpose of the invention is to create an air guide device with a reversible air flow, which MOI would be manufactured without large
    10 costs and to be applicable for agricultural machines of high power class. The goal is achieved by the fact that in the stern of the self-propelled field
    15 the shredder is an air chamber with side windows and one top opening. A water cooler is located in front of the side windows in the direction of travel. Kor20 mova part is lined with perforated metal casing. At the top, the air inlet of the air chamber at the height of the upper water tank of the cooler is located in the frame with the blower body bowls placed on it. The bed is placed on a rotating shaft, which is located in the partition between the engine compartment and the rear wall.
    30 The same axial fan disk is fixed to the same shaft, in which the rotating bed with the cups of the blower body is located so that the ends in the plane of the bed are approximately in the shape of a cone bowl
    35, the blower bodies are located on the bed symmetrically with respect to the plane of the disk of the axial fan and the plane of the bed. To seal the tank with air from outside air containing dust and plant parts, flexible insulating elements are used, located between the perforated metal casing and the cooler, as well as 45 between the cooler and the tank; with air. Between the upper hole of the air chamber and the frame, preferably adjustable flexible insulating elements are reinforced. The air is drawn in only on the suction side in the direction of the disk movement of the axial fan and the air inlet opening into the air chamber and
    55 is blown out through the back. axial-flow fan outside the air chamber; air outlet hole; under normal cooling conditions, the air disk of the axial fan is sucked through the air inlet opening below the frame, through the water cooling radiator and the outer perforated metal case and blown out through the air outlet above the stand diagonally up and back. To clean the perforated metal casing from particles of straw and the size of the bowl of the blower body from the control cabin, by means of, for example, a cable pull and a pulley connected to the bed, they are turned on. Thus, the air inlet and outlet holes change their position relative the air chamber: the inlet opening is above the bed and the opening; release - lower in the air chamber. The air is sucked in the direction of movement from above and is passed through the air chamber, water cooling radiator, to the perforated metal skin xy. The excess pressure arising inside the perforated metal casing contributes to the detachment and falling off of particles of straw, moth and dust. Thus, an expensive transfer mechanism is not required to drive an axial fan. FIG. 1 shows a field grinder with an air guide, side view, FIG. 2 the air guide in normal position; in fig. 3 is a section A-A in FIG. 2; in fig. the same in the cleaning position. In the self-propelled field grinder 1 in the aft part there is a unified drive unit 2c located in the direction of movement of the engine 3. At the rear of the engine 3 in the air chamber k is located opposite the water cooling radiator 5. Installed at the center of the water cooling radiator 5 at the height of the upper tank With longitudinally longitudinally in the direction of motion, the shaft 6 with at least one axial fan 7 is based in the partition 8 and the rear wall 9 on bearings 10 and 11, respectively. Shaft 6 has a rotary bed 12 connected to an axial fan surrounded by the bowls of the blower housing 13. On the shaft 6, in front of the partition 8, there is a V-belt pulley I, and behind the partition is a rope pulley 15 connected to the bed 12. The air chamber in the area of the water cooling radiator 5, there are holes in the center of the bed 12 for air inlet and outlet. By means of the insulating elements 16, the air chamber k is sealed relative to the bed 12 with the bowls of the blower body 13 and the water cooling radiator 5 as well as the perforated metal casing 17. The perforated metal housing is designed so that by tilting up its separate sections, access to the cooler 5 is provided. axial fan 7 is driven by engine 3 through V-belt pulley 18, V-belt 19 on V-belt pulley AND and shaft 6 associated with it. Cases of air casing The chambers are designed in such a way that the air inlet 20 is located in front of the axis (M fan 7 in the direction of movement and the air outlet 21 behind it. The device works as follows. Air is sucked under the bed 12 through the metal perforated housing 17f cooler 5 and the inlet hole air 20 and is blown against the direction of movement through the air outlet opening under the bed 12. To clean the perforated metal casing 17 from the particles of the stems of the bowl of the air casing. the walkers 13 from the control cabin by means of the rope 22 and the rope pulley 15 and the bed T2 are rotated 180 °. The air inlet hole 20 is located above the bed 12, and the air outlet 21 below the bed 12. Air is drawn in by the air inlet 20 above the unified drive unit 2 and injected by the air outlet 21 into the air chamber and from there through the cooler 5 to the perforated metal casing 17. Thanks to inside the perforated OFFp metal casing 17, the overpressure of the particles of the stems is blown off and the perforated metal casing 17 is cleaned. 10 "7753 Recognized as an invention according to the results of the Expertise carried out by the Office for the Invention of the German Democratic Republic.
