Description

Decompression rotary-brushing type heat radiation dust arrester

Technical field

The utility model belongs to the heat radiation dust arrester of large-scale self-propelled agricultural machinery engine, particularly a kind of decompression rotary-brushing type heat radiation dust arrester.

Background technology

The heat radiation dedusting structure of existing large-scale self-propelled agricultural machinery and implement engine mainly is with tank seal at present, because the operating environment of agricultural machinery and implement is poor, a large amount of dusts and broken grass, foreign material are arranged during work, easily seal member being stuck with paste extremely causes ventilation freely not make heat dissipation of water tank bad, easy high temperature, broken grass, the foreign material hole by seal member enters water tank and easily the heat dissipation of water tank slit is blocked in addition, cause equally heat radiation bad, easy high temperature, cause the engine premature wear, have a strong impact on operating efficiency and the service life of engine.

Summary of the invention

The purpose of this utility model is to provide a kind of decompression rotary-brushing type heat radiation dust arrester, and it is rational in infrastructure, and the heat radiation good dedusting effect to engine can guarantee engine work, improves the operating efficiency of engine, increases the service life.

The purpose of this utility model is achieved in that a kind of decompression rotary-brushing type heat radiation dust arrester, be included in collecting cover affixed on the water tank, engine blower matches with collecting cover, affixed the flat square chest of sealing with air intake surface and air outlet in the water tank inlet side, on the air intake surface of the flat square chest of sealing, by bearing block power transmission shaft is installed, be positioned on the power transmission shaft that seals flat square chest and be fixedly mounted with counter-rotating fan, be positioned at affixed decompression impeller on the power transmission shaft that the bearing block right side seals flat square chest, be positioned at affixed rotating brushes on the outer power transmission shaft of the flat square chest of sealing, the bristle of rotating brushes matches with the air intake surface that seals the uniform through hole of flat square chest.

The counter-rotating fan that the gas flow that the fan of the utility model by engine self forms at work drives in the utility model structure rotates as power, thereby being combined in sealing square frame outer surface with electric brush repeatedly revolves brush and is adsorbed on foreign material and grass bits on the ventilating surface, the impeller that reduces pressure simultaneously plays the depressurization that keeps out the wind at the inboard slow circumvolve of sealing square frame, reduce to be adsorbed on foreign material and careless absorption affinity of considering to be worth doing on the sealing square frame outer surface, so that hairbrush is to the removing of foreign material and grass bits, guarantee better the circulation of gas and the heat radiation of water tank, thereby finally guaranteed the normal operation of engine.

The utility model has reduced foreign material and careless heat radiation impact of considering to be worth doing water tank effectively, improved the working time of engine under the summer high temperature state, the most important thing is the utility model technology because the innovation of principle, can reduce significantly the infringement that high temperature causes to engine, thereby can improve the Acceptable life of engine, compare its dust removal efficiency with existing engine radiating dedusting structure and can improve 60%-70%.

The utility model is rational in infrastructure, and the heat radiation good dedusting effect to engine has guaranteed engine work, improves the operating efficiency of engine, has prolonged service life.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described, Fig. 1 is structural representation of the present utility model, Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1, Fig. 3 is the main TV structure schematic diagram of rotating brushes, Fig. 4 is the left TV structure schematic diagram of Fig. 3, Fig. 5 is the main TV structure schematic diagram of decompression impeller, and Fig. 6 is the left TV structure schematic diagram of Fig. 5.

The specific embodiment

A kind of decompression rotary-brushing type heat radiation dust arrester, such as Fig. 1, shown in Figure 2, be included in collecting cover affixed on the water tank 67, engine blower 8 matches with collecting cover 7, affixed the flat square chest 1 of sealing with air intake surface and air outlet in water tank 6 inlet sides, on the air intake surface of the flat square chest 1 of sealing, by bearing block power transmission shaft 5 is installed, be positioned on the power transmission shaft 5 that seals flat square chest 1 and be fixedly mounted with counter-rotating fan 4, be positioned at affixed decompression impeller 3 on the power transmission shaft 5 that the bearing block right side seals flat square chest 1, be positioned at affixed rotating brushes 2 on the outer power transmission shaft 5 of the flat square chest of sealing 1, the bristle of rotating brushes 2 matches with the air intake surface that seals flat square chest 1 uniform through hole.As shown in Figure 3, Figure 4, the structure of rotating brushes 2 is uniform radial brush holder 9 on wheel hub, the uniform bristle 10 that arranging on the operative end surface of brush holder 9.Such as Fig. 5, shown in Figure 6, the structure of decompression impeller 3 is fan-shaped plate blade for arranging symmetrical two at wheel hub, and two plate blades are positioned at same plane, and the vertical projection of plate blade is vertical with the axis of the impeller 3 that reduces pressure.

Operation principle of the present utility model: carry generation air rapid flow under fan 8 High Rotation Speeds at engine, counter-rotating fan 4 begins rotation under the air push of rapid flow, while rotates simultaneously with the power transmission shaft 5 driven rotary hairbrush 2 that counter-rotating fan 4 is linked together, hairbrush is close to the outer surface of the flat square chest 1 of the sealing that connects with water tank, the air intake surface that seals flat square chest 1 is comprised of the web plate that is covered with ￠ 1.5 apertures, namely guarantee the unobstructed cooling water tank of air intake, prevent that again crop grass bits from entering the obstruction water tank, the hairbrush rotation can be fallen the eliminating impurities that is adsorbed on the air intake surface that seals flat square chest 1.Decompression impeller 3 is installed in the flat square chest of sealing 1 inboard, rotary speed is lower, its blade plays the effect of the decompression of keeping out the wind in the course of the work, the absorption affinity that causes corresponding with it flat square chest 1 outer surface of sealing to be adsorbed foreign material, grass bits reduces greatly, hairbrush is fallen foreign material and the cleaning of grass bits very like a cork, at utmost to the efficiently radiates heat that has guaranteed water tank 6, thereby finally guaranteed the normal operation of engine, effectively dropped to the loss of engine low.
