An upper cover is arranged on the novel air filter, a fixing jaw is arranged on the upper cover, the fixing jaw is fixed on the filter element cover through fixing bolts, the air inlet is provided with an extension tube, and a filter element amour is arranged in the extension tube. The novel air filter is suitable for small rotary cultivators and villatic manage machines.

Description

New air filter

Technical field

The utility model belongs to a kind of component of farm machinery, specifically, relates in particular to a kind of new air filter.

Background technique

Air-strainer is the necessary parts of microtilling machine and small-sized garden supervisor.When microtilling machine and small-sized garden supervisor, just will aggravate the wearing and tearing of part if suck impurity such as containing dust in the air, so air-strainer must be housed.Air-strainer is made up of filter core and housing two-part.People are that filtering efficiency is high, flow resistance is low, can use and service free continuously the long period the major requirement of air-strainer.But air-strainer suction port in the market is low, and suction dust amount is bigger, causes the filter core easy blocking, is difficult to satisfy people's requirement.

The model utility content

On the low side for the inlet hole that solves existing technology air filter cleaner, make suction dust amount bigger, thereby cause the defective of filter core easy blocking, the utility model provides a kind of new air filter.

The utility model is realized through following technological scheme:

A kind of new air filter comprises base assembly, filter core, filter core cover, and the filter core cover is installed on the base assembly, and filter core is located on the inner base assembly of filter core cover; The top of said filter core cover is provided with suction port.

New air filter is provided with loam cake.

On cover and be provided with fixed claw, loam cake is fixed on the filter core cover through fixing bolt.

Suction port is provided with extension pipe.

Said extension pipe inside is provided with the filter core first.

Compared with prior art; The beneficial effect of the utility model is: the top that suction port is located at the filter core cover; Make suction port improve, more can extension pipe be installed on suction port as the case may be, further improve the height of inlet hole; Effectively reduce the dust amount that sucks in the course of the work, avoided the filter core obstruction; Improve filtering efficiency greatly, prolonged service time.

Description of drawings

Fig. 1 is embodiment one a structural representation;

Fig. 2 is embodiment two a structural representation.

Base assembly in the drawings, 1; 2, filter core; 3, filter core cover; 4, fixing bolt; 5, suction port; 6, loam cake; 7, fixed claw; 8, retaining ring; 9, extension pipe.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Embodiment one: a kind of new air filter, comprise base assembly 1, filter core 2, filter core cover 3, loam cake 6, and filter core cover 3 is installed on the base assembly 1, and filter core 2 is located on the base assembly 1 of filter core cover 3 inside; The top of said filter core cover 3 is provided with suction port 5; Loam cake 6 is provided with fixed claw 7.

Embodiment one when mounted, loam cake 6 is fixed on the filter core cover 3 through fixing bolt 4.

Embodiment two: suction port 5 is provided with extension pipe 9, and said extension pipe 9 inside are provided with the filter core first, and other is identical with embodiment one.

Embodiment two when mounted, an end of extension pipe 9 is fixed on the suction port 5 through retaining ring 8, the other end of extension pipe 9 is fixed by bolts on the loam cake 6 through fixed claw 7; The filter core first can be made by sponge.

The utility model is installed in the utility model on the petrol engine of microtilling machine and small-sized garden supervisor and gets final product in use.Embodiment one is applicable to that the soil is not a too dry, and soil moisture content is better, and the dust of kicking up during operation is less, the situation that the dust height is lower; Embodiment two is applicable to that the soil is dry, and the dust of kicking up during operation is many, dust height condition with higher.
