Description

[Detailed description of the invention] This invention relates to a flat brush structure in a washing machine for root vegetables, etc.

In a machine for washing root vegetables, etc., in which a roll brush and a flat brush face each other while maintaining a transfer space, the items to be washed that are placed in the transfer space are mainly washed by the roll brush, and the flat brush is used mainly for cleaning. The purpose of this brush is to press down on the object to be washed, but depending on the pressing force of the flat brush, the outer skin may peel off, especially for root vegetables such as sweet potatoes, where the outer skin easily peels off, reducing the value of the product as a product. may be significantly reduced.

Therefore, the pressure of flat brushes has traditionally been adjusted using elastic force, but conventional flat brushes have hair-like brushes planted densely on a hard plate material as a substrate.
This flat brush made of hard plate material was elastically supported by springs or the like to adjust the pressing force.

For this reason, although it has the elastic force of a hair-like brush, since a hard plate material is used, the flat brush can only perform general movement, and it is suitable for cleaning individual objects of various sizes and shapes. There are disadvantages in that the pressure cannot be adjusted appropriately, causing peeling of the epidermis and insufficient cleaning.

In addition, when manufacturing flat brushes, the work of planting the hair-like brushes on the substrate is extremely complicated, and the hair-like brushes that have been planted thereon not only have the disadvantage of being easy to remove hair, but also lose their hair after long-term use. Another drawback was that the shaped brush tilted and became useless as a flat brush.

The present invention was developed in view of the above-mentioned drawbacks, and it is possible to appropriately adjust the pressure for each object to be cleaned having various sizes and shapes, and to make the bristles of the brush long. Another object of the present invention is to provide a flat brush that is easy to manufacture and can withstand long-term use.

In this case, a plurality of roll brushes 1, 1, . In a washing machine for root vegetables, etc., in which a flat brush 2 is opposed to the side surface and the opposing part is configured as a transfer path S for the object to be washed 15, a large number of elastic rods are installed on the surface of an elastic substrate 2a made of an elastic material such as rubber. 2b
The flat brush 2 is formed by integrally molding and standing upright, and the thick elastic rod 2b has a large diameter portion 2b' at its base end.
This invention relates to a flat brush structure characterized in that the thin elastic rods 2b are formed into elongated lengths to loosen the contact with the object 15 to be cleaned. To explain based on the example shown, the washing machine A has a plurality of roll brushes arranged in parallel in the transfer direction (direction of arrow a).
... and an endless flat brush 2' as a flat brush 2 suspended above the roll brushet in a floating state, and the roll brushet... formed a water tank 3'. A pulley 5 is provided on the spindle 4 of each roll brush, which is rotatably supported on the upper part of the machine frame 3 perpendicular to the transfer direction.・・・・・・
By winding the transmission belt 6 around the support shaft 4 and connecting the main boot turf provided on the support shaft 4 and the motor pulley 8 via the deceleration belt device 9, each roll brush...
... rotates in conjunction with the drive motor 10 (in the direction of the arrow)
It is something that makes you

A support frame 11 is elastically supported on the upper surface of the machine frame 3, and support rolls 12.
12 is pivotally supported, and an endless flat brush 2' is hung between the support rolls 12. The upper surface of G... and the transfer space S are held and faced to each other.

In this case, the support frame 11 is the support rod 1 erected on the machine frame 3.
3 penetrates the flange 11', and is elastically supported by supporting both upper and lower surfaces of the flange 11' with springs 14 and 14 fitted to the support rod 13.

The flat brush 2 has an elastic substrate 2 made of rubber or synthetic resin.
A large number of elastic rods 2b as cleaning bodies are integrally molded and erected on the surface of a, and the bases of the elastic rods 2b are provided with large diameter portions 2b'.

In this case, it is preferable to make the diameter of the elastic thin rod 2b as small as possible, but in this embodiment, the outer diameter is about three ribs, and the large diameter portion 2b is
The outer diameter of b' was approximately 51rgIL.

This large diameter part 2b' is for reinforcing the narrow rod 2b, and by forming the same large diameter part 2b', the narrow rod 2b can be formed into a long length, and furthermore, the narrow rod 2b can be formed into an even thinner rod. It is also possible to reliably maintain the standing state.

Also, as the other side of the narrow rod 2b on which the large diameter portion 2b' is formed,
As shown in FIG. 5, the outer diameter may be tapered from the large diameter portion 2b' of the base to the tip of the narrow rod 2b, or as shown in FIG. 6, the outer diameter may be tapered toward the base. Several stages of large diameter portions 2b' may be provided with successively larger outer diameters.

In addition, binding of the narrow rods 2b can be prevented by arranging the narrow rods 2b, 2b roughly adjacent to each other with an interval corresponding to the outer diameter of the large diameter portion 2b'. It is preferable to decide as appropriate in consideration of the difficulty of molding, manufacturing cost, etc., or the type of the object 15 to be cleaned.

In addition, what is indicated by 16 in the figure is a guide plate for loading the items to be washed 15;
7 is the discharge guide plate.

Moreover, the one shown in FIG. 7 is a washing machine using a flat brush 2 formed in a belt shape, and a support frame 1 elastically supported on a machine frame 3.
One end of a belt-shaped flat brush 2'' is pivotally attached to the front end of the belt-shaped flat brush 2'', and a spring 18 is connected to the other end of the belt-shaped flat brush 2''.

In the figure, reference numerals 19 and 19 indicate plate brushes provided on both sides of the band-shaped flat brush 2'', and are provided on the lower surface of the support frame 11.

20 is a presser roll for the band-shaped flat brush 2'.

Therefore, when the object 15 to be washed is thrown in from the input guide plate 16, the object 15 to be washed moves in the direction of arrow a while being pressed by the flat brush 2 and being washed by the roll brush... However, with this transition, the flat brush 2 can be used to clean individual objects 1 having various sizes and shapes.
5, the thin elastic rods 2b as well as the elastic substrate 2a are deformed freely due to their elasticity, and the pressing force can be appropriately adjusted regardless of the size and shape of the object 15 to be cleaned. Since the substrate 2a can be lifted locally with respect to the object 15 to be cleaned, the pressing force is reduced and there is no fear that the skin of the object 15 to be cleaned will be peeled off.

Since the present invention is configured as described above, the pressing force of the flat brush 2 can be appropriately adjusted by the flat brush 2 itself, and there is no risk of peeling off the outer skin of the object 15 to be washed.

Furthermore, since the elastic substrate 2a is used, it can be used in an endless form as in the embodiment of the present invention, which not only allows for a wider range of uses, but also allows for a flat rod 2b to be integrally molded with the substrate 2a. In addition to making the brush 2 easier to manufacture, the thin rods 2b do not fall off even when the substrate 2a is deformed, and the lifespan of the flat brush can be extended.

Furthermore, since the base end of the elastic thin rod 2b is formed to have a large diameter, the length of the thin rod itself can be made long, and it is possible to maintain the strength of the waist while making the thin rod flexible. This has the effect that the contact state with respect to the object to be washed is moderately relaxed so that the outer skin of the object to be washed will not be peeled off.
