Description
Technical field
The invention belongs to field of agricultural machinery, specifically about the rotary cultivator that new structure gas handling system is housed.
Background technique
Rotary cultivator is a kind of conventional farm machinery, with other farm machineries unlike, rotary cultivator mainly carries out hack operation, and working depth is about underground 15cm-25cm.Working environment has a large amount of airborne dust.In existing rotary cultivator, the inadequate science in position of gas handling system especially suction port, often causes the situation sucking a large amount of granule foreign and dust, to such an extent as to engine life is affected, engine vibration can be caused large, and noise is large, discharges the problems such as not up to standard simultaneously.
Summary of the invention
The present invention is for solving the problems of the technologies described above, and the working environment special for rotary cultivator and crawler, from the structural feature walking rotary cultivator, work out a kind of air inlet system being exclusively used in rotary cultivator of novel structure, and are arranged on rotary cultivator body.
The present invention is achieved in that
Be exclusively used in crawler from walking the gas handling system of rotary cultivator, its gas handling system comprises secondary filter and strainer and the seam of air filter mounting plate; The secondary filter air outlet of described gas handling system is connected with the suction port of diesel engine through flexible pipe.The air outlet of strainer is run through air filter mounting plate seam with described secondary filter suction port with flexible pipe through right-angle elbow pipe and is connected, and strainer is that umbrella founds shape and stands on the rear side of air filter mounting plate and be fixed in the seam of air filter mounting plate.Described right-angle elbow pipe inside is provided with adsorption type dedusting film.Through research and experiment, adopt and right-angle elbow pipe is set and can effectively reduces the particulate matter entering secondary filter in the mode that pipe bent position arranges adsorption type dedusting film.
Strainer and secondary filter can be fixed on homonymy or the heteropleural of the seam of air filter mounting plate.
In order to reduce the noise that gas handling system produces, noise-reducing sponge can be provided with at flexible pipe and right-angle elbow pipe inside.
Secondary filter air outlet place is provided with dust monitoring device, carries out alarm more renew cartridge when dust index exceeds standard.The suction port of strainer can be provided with the upper cover in umbrella.
Maximum effect is played for making this gas handling system, crawler based on this design walks rotary cultivator certainly, comprise frame and be located at power system on frame, be located at frame under the crawler belt of both sides and drive unit, power system comprises diesel engine, air inlet system, silencing apparatus, radiator shell, cooling system, fuel tank, moving gear box, Power output transmission case; , gas handling system is positioned at directly over diesel engine, and gas handling system is in crawler on the medial axis walking rotary cultivator left and right directions, and is positioned at the middle part of fore-and-aft direction.In order to make the dust of suction minimum, test through the suction port of gas handling system being separately positioned on 1/4 position of left and right directions, 1/3 position and medial axis, when conclusion shows to be arranged on medial axis, reduce by 17.6% and 13.5% respectively than 1/4 position and 1/3 position dust granules thing intake.Therefore be placed on medial axis is optimal location.
Gas handling system is positioned at the dead astern of seat, and the secondary filter of gas handling system in horizontal direction sleeping shape is positioned at above diesel engine, and secondary filter is positioned at the below of secondary filter guard shield simultaneously, is placed in the front lower place of roll-over protective structure and is fixed in the seam of air filter mounting plate.
Air inlet rough filtering device present position higher than the sitting posture worker crown, lower than roll-over protective structure.
The suction port of air inlet rough filtering device is higher than rotary cultivator horizontal plane 1m-2m, and preferably, this suction port is positioned at the level height higher than work surface and ground 2m.
This crawler being configured with special gas handling system walks rotary cultivator certainly, sucks dust and obviously reduce during operation, and abrasion of engine cylinder is comparatively slow, increases service life of aeroengine, realizes reduction noise simultaneously, discharges the effects such as more environmental protection.
