Abstract
The utility model discloses an air filter for mini-cultivator, comprising a first filter and a second filtering shell on top of which an air inlet is communicated with an air outlet of the first filter, wherein on the second filtering shell a connector is arranged, and in the second filtering shell a filter element is fixed. The main improvement lies in that the first filter is in bathtub construction, and the foam filter element is arranged on the supporting filter netted board, besides, the bathtub first filter is in fixed connection with the second filtering shell. The utility model has the advantages of that at first, the filtering rate can be higher than 99%, the second, the technical structure is simple, resistant to block, easy to clean, and can be reused, the third, the maintenance is convenient and one can decides whether the filter need to be detached and washed by observing into the transparent shell on the bathtub first filter at any time, besides, the bathtub first filter has a satisfying capacity of dust containing, so the cleaning cycle is lengthened, correspondingly extending the useful age of the product.
Description
Technical field
The utility model relates to a kind of air-strainer, specifically refers to the air-strainer that microtilling machine is used.
Background technique
A lot of air-strainer also had the one-level strainer before filter core, just filter cap and basin shape prefilter as cyclone tube, blade ring, taper.Their structure has nothing in common with each other, but all just separates with the centrifugal principle grit that weight is bigger, allows the tiny grit of second level filter element filtering, the secondary filter work load is alleviated, life-saving, reliable operation.And second level filter element filtering mainly contains the empty filter of dry type, the empty filter of oil bath type and the empty filter of oil immersed type etc., and it respectively has pluses and minuses.The empty filter of diesel engine using mainly contains following several structure on the microtilling machine at present: 1, dry-type air cleaner, owing to have the papery filter core,, just will clean in 3～5 days, and the papery filter core can not be washed the maintenance trouble so easily stop up; 2, oil bath combined type air-strainer, though be difficult for stopping up, but filter efficiency is low, resistance is big, simultaneously owing to the easy run-off the straight when having determined that it uses of the working environment of microtilling machine, jolt, machine oil in the oil sump is easy to produce fluctuation and enters the firing chamber, thereby influences the service behaviour of diesel engine and the filtering effect of empty filter, and it is frequent to change oil; 3, awl hat type air-strainer, it is simple in structure, but filter efficiency is low, and the dust of discharging has the possibility that is inhaled into again.Because microtilling machine has determined that with the structural feature of diesel engine the installing space of empty filter is narrow and small, easily jolt during work, therefore empty filter volume can not be too big on the one hand, then be not suitable for as eddy flow tubing strainer, empty on the other hand filter can not have oil sump, because the use object of microtilling machine has also determined it that too high usage requirement can not be arranged, i.e. maintenance wants simple simultaneously.And the empty filter that uses at present can't satisfy such requirement.
Summary of the invention
At existing microtilling machine air-strainer above shortcomings, the purpose of this utility model provides a kind of filter efficiency height, easy maintenance, microtilling machine air-strainer simple in structure.
The technical solution of the utility model is achieved in that the microtilling machine air-strainer, comprise prefilter and cascade filtration shell, cascade filtration shell upper end suction port and the butt joint of prefilter air outlet, on the cascade filtration casing wall, be provided with connecting head, be installed with filter core in the cascade filtration shell, its improvement is: described prefilter is a basin shape prefilter, and filter core is foam filter elements and is arranged at support with on the filter core web plate that basin shape prefilter and cascade filtration shell are bolted to connection.Its Placement is, be provided with lower cover plate at the cascade filtration outer casing bottom, bolt passes basin shape prefilter, cascade filtration shell upper-end surface, filter core gas-entered passageway, filter core web plate lower end surface from top to bottom successively and with lower cover plate they is connected, and is arranged with on bolt filter core web plate and the fastening nut of lower cover plate.
Further improve and be: the transparent cover of end housing for ease of observing on the described basin shape prefilter.
Between lower cover plate and cascade filtration shell, be provided with seal ring.
Described bolt is a stud bolt, and bolt top is provided with the fastening nut of basin shape prefilter, is provided with iron gasket and gasket seal from top to bottom successively between nut and basin shape prefilter.
Compared to existing technology, the utlity model has following advantage:
1, filter efficiency height can reach more than 99%.
2, process structure is simple, be difficult for stopping up, owing to cancelled the papery filter core, thus easy cleaning, and foam filter elements itself is reusable.
3, easy maintenance, whether can observe empty filter at any time by basin shape prefilter upper end transparent cover needs to pull down cleaning, and since basin shape prefilter to store up grey ability strong, so the Cleaning period prolong, correspondingly improved product working life.
Description of drawings
Fig. 1-the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, from the figure as can be seen, the utility model comprises basin shape prefilter 5 and cascade filtration shell 6, cascade filtration shell 6 upper end suction ports and 15 butt joints of basin shape prefilter air outlet, on cascade filtration shell 6 walls, be provided with the connecting head 12 that is connected with diesel engine, be installed with foam filter elements 8 (both can be that the dry type foam filter elements also can be the oil immersed type foam filter elements) in the cascade filtration shell 6, foam filter elements 8 be arranged at support with on the filter core web plate 7 to prevent that filter core is out of shape under suction function, the gas-entered passageway 13 of foam filter elements faces prefilter air outlet 15.Basin shape prefilter 5 is fixedlyed connected by bolt 9 with cascade filtration shell 6, and its Placement is, is provided with lower cover plate 11 in cascade filtration shell 6 bottoms, is provided with seal ring 10 between end face contacting of lower cover plate 11 and cascade filtration shell 6.One stud bolt 9 passes basin shape prefilter 5, cascade filtration shell 6 upper-end surfaces, filter core gas-entered passageway 13, filter core web plate 7 lower end surfaces and lower cover plate 11 from top to bottom successively they is connected.
As can be seen, just filter the inlet hole 14 that back air enters for some confessions around the attachment hole that passes for bolt in the middle of present embodiment cascade filtration shell 6 upper-end surfaces, attachment hole from the figure.Bolt 9 is fixed by welding manner and cascade filtration shell 6 after passing attachment hole, after each parts changes cleaning, can apace individual parts be reinstalled and put in place like this.Be provided with the nut 1 that basin shape prefilter 5 is fastening on bolt 9 tops, 5 of nut 1 and basin shape prefilters are provided with iron gasket 2 and gasket seal 3 from top to bottom successively.Be provided with the nut 1 that filter core web plate 7 and lower cover plate 11 is fastening in bolt 9 bottoms.For the ease of turning, above-mentioned all nuts 1 are dish shape nut, like this even without instruments such as spanners, also can dismantle easily or fastening.
