Description

[Detailed description of the invention] The present invention relates to a dust removal filter mounting structure for agricultural machinery, which is modified so that the filter can be fixed and unfixed easily and quickly, and by effectively utilizing the structure of the filter holder. To simplify the fixing structure and make filter fixing economically advantageous, and to efficiently perform filter inspection and replacement work.

Next, embodiments of the present invention will be described based on illustrative drawings.

As shown in Fig. 1, crawler type traveling machine platform 1
A reaping pretreatment device is provided with a driving unit, a riding-type driving unit 2, and a threshing unit 3, respectively, and which causes and reaps planted grain culms as the machine travels, and supplies the reaped grain culms to the threshing unit 3. 4 is connected to the front part of the traveling machine base 1 to constitute a combine harvester.

As shown in FIG. 2, the driving unit includes an engine 6, an engine cooling radiator 7 disposed above the engine 6, a rotating fan 8, etc. in the engine bonnet 5. A cylindrical body 9 is provided between the radiator 7 and the vicinity of the back of the detachable side wall 5a of the net 5, and the engine cooling air from the air intake port 10 formed in the side wall 5a is directed to the radiator 7. A removable dust removal net 12 is attached to the end of the side wall of the cylindrical body 9 to form a path 11 for introducing and supplying the cooling air, and a shape-retaining frame is attached to the end of the side wall of the cylinder 9 to act on the cooling air. Sponge for dust removal with 13 14
is attached to the cylindrical body 9, and the dust removal net 1
2, a brush 15 is swingably attached to the brush 15 for scraping off dust attached thereto. That is, the cooling air is introduced into the radiator 7 from the air intake port 10 via the path 11 by the suction force of the fan 8, thereby cooling the engine.
Furthermore, the action of the dust removal net 12 and the sponge 14 prevents dust from being supplied to the radiator 7 together with the cooling air and adhering thereto, and the dust removal net 12 is cleaned by the brush 15, and the cooling air is generated by the adhering dust. It is configured to prevent a decrease in supply efficiency.

The structure for attaching the sponge 14 to the cylindrical body 9 is constructed as shown in FIGS. 3 and 4.

That is, an abutment part 16 is formed on the cylinder body 9 by bending to extend around the entire circumference of the cylinder, and a ring-shaped ring made of round steel bar is bent to press the sponge 14 onto the abutment part 16. Part 1
7 is attached to the support fitting 18 attached to the inner side of the upper wall of the cylinder 9 so as to be swingable around the axis X, and a pair of left and right bent sheet metals are attached to the inner side of the lower wall of the cylinder 9. The ring-shaped member 1 is attached with
A pair of locking portions 19, 19 are formed for separately locking and releasing both ends of the ring member 17, and in order to attach the sponge 14, as shown in FIG. The ring-shaped member 17 and the abutment part 16 cooperate with each other to clamp the outer circumference of the sponge 14 over almost the entire circumference, and then To remove the ring-shaped member 1, as shown in Fig. 3A,
The sponge 7 is disengaged from both the locking parts 19, 19, and is swung away from the abutment part 16 in a non-operating state, and the sponge 14 is pulled out.

Further, each of the locking portions 19 is configured by engaging the ring-shaped member 17 in a state in which the ring-shaped member 17 is elastically deformed around the attachment portion to the support fitting 18 so that both ends of the ring-shaped member 17 are closer to each other than in the free state. The locking portion 1 of the ring-shaped member 17 is configured to be released, and the elastic restoring force due to the deflection deformation of the ring-shaped member 17 causes the locking portion 1 of the ring-shaped member 17 to be removed.
It is configured to prevent it from coming off from 9.

Note that the ring-shaped member 17 may be a closed type with both ends connected, or a ring-shaped member formed into a round shape,
It is also possible to use a structure made of strips or square steel bars. If the rod-like member has a rectangular cross-sectional shape, such as a square rod, the corners of the rod-like member bite into the sponge 14, thereby firmly preventing the sponge 14 from coming off.

In addition, to constitute the locking portion 19, the ring-shaped member 1
7 may be configured to engage and disengage in an elastically deformed state in which one side thereof is curved around both ends.

Furthermore, instead of the sponge 14, a dust-removing net or punched metal may be used, and these are collectively referred to as the dust-removing filter 14.

In summary, in the dust removal filter mounting structure for agricultural machinery according to the present invention, the cylindrical body 9 forming the engine cooling air supply path 11 is provided with an abutting portion 16 for the dust removal filter 14 that acts on the engine cooling air. The elastically deformable ring-shaped member 17 for holding the filter 14 in cooperation with the abutting portion 16 is switched to a non-operating state and is attached so as to be swingable, and the ring-shaped member 17 is held in the operating state. The locking part 19 for
It is characterized in that it is formed in the cylindrical body 9, and that the ring-shaped member 17 is configured to engage and disengage while being elastically deformed.

In other words, it is possible to switch between the active state and the non-active state with the simple operation of swinging the ring-shaped member 17, compared to the conventional method which requires a large number of filter tightening screws. hand,
The filter 14 can now be fixed and unfixed to and from the cylindrical body 9 easily and quickly. Moreover, since the elastic restoring force caused by the deflection deformation of the ring-shaped member 17 is effectively used as the force for preventing the ring-shaped member 17 from coming off, the ring-shaped member fixing structure can be easily integrated into the locking part 1.
It has become possible to construct a simple structure that only requires the provision of 9. As a result, the filter 14 of this model, which has a large amount of straw debris and the like and needs to be cleaned frequently, can be easily and quickly installed and removed, and the cleaning work can be carried out efficiently at a low cost.
