Description

[Detailed Description of the Invention] The present invention relates to a cleaning machine for top-coated agricultural products such as sweet potatoes, and particularly relates to the structure of its roll brush.

The reality these days is that if agricultural products such as sweet potatoes are put on the market with soil still on them, their commercial value is low, whereas those that have been washed with the soil removed are valued higher and sell better.

In addition, it has become common to remove soil and wash it for reasons other than appearance, such as for quantifying products.

Therefore, apart from cleaning soiled agricultural products by hand, washing machines are used to efficiently wash large quantities of crops.

A conventional washing machine for agricultural products such as sweet potatoes will be explained using FIGS. 1 and 2. A large number of roll brushes 5 having uniform brush length are arranged in close contact with each other in the longitudinal direction within the same plane and are rotatably arranged in the same direction.

The roll brush 5 is provided with a sprocket 6 at each end, and is connected to a rotational drive source installed at the bottom of the main body of the washing machine by passing a chain belt 7 around the roll brush 5.

Furthermore, each roll brush 5 is provided with a sprocket 9 that spans a chain belt 8 so that the roll brushes 5 can interlock with each other and rotate in the same direction.

Note that an appropriate number of roll brushes of the same shape are used depending on the model, and the hardness and softness of the brushes are selected appropriately, but the shape is the same, and in particular, the length of the brush is uniform. The brush surface is linear.

On the other hand, a lid 10 is placed on the top of the washing machine main body 1,
This lid body 10 is equipped with a fixed brush 11 that faces and is parallel to the roll brush 5.

The fixed brush 11 is made of a plate whose length is approximately half the width of the lid frame 12, and one end is attached to the inner edge of the lid frame 12 with a hinge 1.
3, the other end abuts against a bullet 15 fixed to the top plate 14.

The top plate 14 has a roof shape and forms an upper space so that each other end of the fixed brush 11 can move up and down.

The fixed brushes 11 are arranged in a required number in the depth direction in FIG.

Furthermore, a bolt 16 is provided at the side end of the lid frame 12 to be attached to and removed from the washing machine main body 1, and the lid frame 12 is attached to the bolt 16.
Coil springs 17 and 17a are placed above and below the
A bolt 16 is screwed onto the upper edge of the washing machine main body 1 with a bullet interposed therebetween, and the lid body 10 is fixed thereon.

A water supply pipe 18 that supplies washing water to the lid 10 and the receiver of the washing machine main body 1 is supported on the top plate 14, and both ends of the water supply pipe 18 are formed as nozzles 20 inside the lid 10. It's open.

21 is a rubber hose attachment/detachment port for water supply. Then, when the chain belt 7 rotates and one of the roll brushes 5 rotates via the sprocket 6, the chain belt 8 rotates and all the roll brushes 5 rotate in the same direction.

Then, when the sweet potato 23 is introduced from the input chute 22 and water is supplied to the water supply pipe 18, the sweet potato is transferred to the roll brush 5.
It is transmitted while rolling on the surface.

During this transmission, the soil is scraped off by the roll brush 5 and the fixed brush 11, and the soil is washed away by the jetted stream of cleaning water and reaches the outlet chute 24.

However, according to the cleaning machine having such a configuration, the two fixed brushes 11 in the - row are screwed together so as to be swingable, and the other ends are mutually floating in the center of the roll brush 5. Hinge 13 when transmitting 23 etc.
The side of the hinge 13 becomes lower, and the sweet potato 23 and the like get clogged with the hinge 13 and remain unwashed, or the following sweet potato 23 stagnates, significantly impeding the cleaning efficiency.

Therefore, every time such an accident occurs, it is necessary to remove the lid 10 and remove the sweet potatoes 23 and the like.

In addition, all of the sweet potatoes 23 and the like to be cleaned are not only oval-shaped and easy to clean, but also many that are difficult to clean, such as those with thin tips, those with insufficient growth, and those with malformed shapes.

These items are not easy to clean, especially as they roll around in the washing machine and rarely collide with the roll brush and cleaning brush, and the thin parts at the ends are difficult to clean. It is.

For this reason, in order to ensure thorough cleaning, it is necessary to inspect items that have been washed in various ways to see if there is anything left unwashed, and to re-wash by hand each time there is a part left unwashed, such as sweet potatoes.

Thus, although there is an advantage that mechanical cleaning can be performed without depending on availability, there is a disadvantage that cleaning efficiency is low.

The purpose of the present invention is to eliminate such drawbacks in conventional cleaning machines, and by improving the structure of the brush surface of each brush, especially the roll brush, it is possible to achieve efficient cleaning without clogging the transmission. It provides an opportunity for

An embodiment of the present invention will be described below with reference to FIGS. 3 to 9.

In FIGS. 3 to 9, the same or corresponding parts as those shown in FIGS. 1 and 2 will be described using the same reference numerals.

A large number of roll brushes 5 in the present invention are also arranged in close proximity in the longitudinal direction on the same plane and are arranged in parallel so as to be freely rotatable in the same direction. As in the conventional case, each roll brush 5 is connected to a rotational drive source installed at the bottom, and further includes a sprocket 9 that spans a chain belt 8 so that each roll brush 5 can rotate in the same direction in conjunction with each other.

Therefore, the present invention is characterized by the structure of its roll brush.

FIG. 9 is a sectional view of the roll brush 5 according to the present invention,
As shown in the figure, the length of the brush at both ends of the roll brush 5 is slightly longer than that at the center, and the brush surface as a whole forms a curved surface with a longer brush length at both ends. It looks like this.

In the illustrated roll brush 5, brushes of the same length are planted in an area of about 1n of the total length of the central portion in the longitudinal direction so that the brush surfaces are linear, and both ends are attached to the central brush. Bristles approximately 1.6 times as long are implanted, and the bristles are implanted so as to form a gently curved surface between them.

This roll brush 5 only needs to have a curved brush surface as a whole, and the specific length of the brush,
The degree of curvature is appropriately selected depending on the hardness of the brush, the relationship with the cleaning brush, etc.

On the other hand, the fixed brush 11 facing the roll brush 5 has its brush lengths shortened at both ends so that its brush surface follows the curved surface formed by the brush surface of the roll brush 5.

Therefore, the gap between the roll brush 5 and the fixed brush 11 is curved and kept constant, and the pressure of the brush against the sweet potato 23 and the like is kept uniform.

Further, in addition to the structure of the roll brush, the cleaning machines shown in FIGS. 3 to 9 have the following points improved compared to the conventional example.

The top plate 14 of the lid body 10 is not roof-shaped but flat plate-shaped, and the lid body frame 1
2 is screwed at both ends in the longitudinal direction.

The lid body frame 12 is provided with flanges 25 and 26 extending horizontally in both the inside and outside directions on both sides in the longitudinal direction, and the outside flange 25
and the upper part of the washing machine main body 1 are held together by a bolt 16 with a coil spring 17 interposed therebetween.

In the illustration, the bolt 16 has a coil spring 17 interposed only on the upper side, and no fill spring is interposed between the flange 25 and the washing machine main body 1, but as in the conventional case, each bolt 16 has two coil springs. 17, 17a
may be interposed.

On the other hand, a brush holder 27 is mounted on the inner flange 26 and supported by a bolt 29 with a coil spring 28 interposed therebetween, and the bolt 29 is screwed into the flange 26 or fastened with a nut (not shown). has been done.

As shown in FIG. 6, this brush holder 27 is a groove-shaped body having both wing portions 30 and can be fitted into the width of the lid frame 12.

A locking hole 31 into which a bolt 29 is loosely fitted is formed in both wing parts 30, and a fixed brush 11 is attached to a screw 23 on the bottom surface of the groove-shaped body.
It is fixed with etc.

A plurality of such brush holders 27 are mounted on the lid frame 12 so as to be movable up and down, facing the row brushes 5 arranged horizontally.

Note that the one of the fixed brushes 11 closest to the input chute 22 is slightly inclined to face the input chute 22, and
It is provided so that it can swing freely.

As shown in FIG. 8, this fixed brush lla is provided with a hinge 33 at the bottom of the negative side end and a stopper 34 at the top of the other side end.

The hinge 33 is fixed to the lateral inner surface of the lid frame 12, and the stopper 34 is placed on the flange 26 to prevent the fixed brush lla from falling, and the entire fixed brush 11a holds the hinge 33 higher than the stopper 34. It is set high and slanted.

An elastic body 35 made of a thin steel plate is connected to the upper part of these fixed brushes 11 in the longitudinal direction in the center of the lid frame 12, and controls the movement of each fixed brush 11 so that they are related to each other. This is to form a motion that has been made.

Note that a banner 36 made of rubber or the like is provided on the discharge chute 24 to prevent droplets from scattering to the outside.

Therefore, the operation of the present invention will be explained.

As with the conventional device, the roll brush 5 is rotated and sweet potatoes 23 with soil are introduced from the input chute 22, and the sweet potatoes 23 and the like are sequentially transmitted to the discharge chute 24 via the roll brush 5.

Since the brush surface of the roll brush 5 forms a curved surface, small parts such as sweet potatoes are also cleaned by colliding with the cleaning brush at the end of the roll brush 5.

Since the cleaning surface is curved, sweet potatoes and the like are collected in the center and transmitted, improving cleaning efficiency.

Furthermore, during this transmission, the distance between the roll brush 5 and the fixed brush 11 is increased or decreased depending on the size of the sweet potato 23 or the like or due to its rolling.

This is the bolt 2 that presses the fixed brush 11 against the lid frame 12.
9 and the coil spring 28, the sweet potato 23
If the situation is too strong, the fixed brush 11 is lifted up from the lid frame 12 against the force of the coil spring 28.

Therefore, the coil spring 28 may be adjusted to press the fixed brush 11 against the lid frame 12 with a strength that does not interfere with the transmission of the sweet potato 23 and the like during work.

If a problem occurs during transmission, the pressing force of the coil spring 28 can be adjusted by turning the left and right bolts 29 of the fixed brush 11 at that location in a direction that loosens them.

Thus, while the sweet potatoes 23 and the like are being sprayed with water while reaching the discharge chute 24 from the input chute 22, they roll between the roll brush 5 and the fixed brush 11, and the soil attached thereto is washed away.

According to the present invention described above, since the brush surface of the roll brush is not linear but curved, the objects to be cleaned can be gathered at the center during transmission, and the cleaning efficiency can be increased. It can clean every detail of the object evenly and completely cleans it regardless of the shape of the object to be cleaned.
