Description

[Detailed Description of the Invention] The present invention relates to a washing machine for agricultural products with sweet potatoes and the like, and particularly relates to an improvement of a washing 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.

To give an overview of conventional washing machines for sweet potato and other agricultural products, a plurality of roll brushes are closely fixed in a rectangular receiver in parallel and rotatable in the longitudinal direction. A plurality of fixed brushes are fixed to the lid of the receiver, and a pipe for spouting cleaning water is installed on the receiver.The roll brushes are driven to rotate by a motor, and soil is discharged from a chute attached to one end of the receiver. When sweet potatoes, etc., are inserted, they are transferred to a roll brush, and while the sweet potatoes, etc. roll, the soil is removed by washing water and the fixed brush, and they are washed from the other end of the receptacle and then exited to the outside.

However, the roll brush and the fixed brush in this conventional example are each made of brush bristles of the same length planted on a shaft or a plate, and because both are disposed horizontally facing each other, the tips of the bristles The parts were in contact with each other in a horizontal straight line.

Therefore, when sweet potatoes, etc. roll between the roll brush and the fixed brush, some of the soil may not be sufficiently removed and may remain.

That is, agricultural crops such as sweet potatoes are usually elongated bodies with small diameters at both ends, forming a so-called spindle.

Therefore, when the roll brush and the fixed brush come into contact with the large diameter portion, both brushes cannot come into contact with the small diameter portion, and therefore the small diameter portion is not cleaned.

In addition, the fixed brush can be moved up and down, and the gap between it and the roll brush can be adjusted as appropriate to prevent stagnation in the transmission of sweet potatoes, etc., so the roll brush can be adjusted to fit the large diameter part. When the gap between the fixed brush and the fixed brush is adjusted, the brush does not come into contact with the small diameter part, and as a result, only the large diameter part is cleaned, and the small diameter part comes out with dirt still attached to it.

In view of these circumstances, the present invention aims to improve the roll brush and the fixed brush, and provides a washing machine for agricultural products with soil that can completely wash agricultural products such as sweet potatoes.

The present invention provides a washing machine for agricultural crops with soil as described above.
The roll brush and the fixed brush are characterized by having shorter bristles implanted in the center part than in both end parts, so that a vertically curved space is formed between the roll brush and the fixed brush.

The configuration of the present invention will be explained below based on an embodiment shown in the drawings.

FIG. 1 is a longitudinal sectional view of the main part of the washing machine in the longitudinal direction, and FIG. 2 is a sectional view taken along the line A--A in FIG.

As shown in the figure, the washing machine main body 1 has a receiver 4 having an inlet 2 and an outlet 3, and inside the receiver 4, a large number of roll brushes 5 are closely spaced in the longitudinal direction in the same plane, and are moved in the same direction. They are arranged in parallel and can rotate freely.

One of the roll brushes 5 is equipped with a sprocket 6, and is rotated by a chain belt 7, and is attached to the base 1a of the washing machine main body 1.
It is connected to a rotational drive source such as a motor installed in the

Furthermore, each roll brush 5 is provided with a sprocket 9 that spans a chain belt 8 so that it can rotate in one direction in conjunction with each other.

As shown in FIG. 3, this roll brush 5 has bristles that are shorter in the center than in both ends, and the circumferential side of the center is curved by a dimension d more than in both ends.

On the other hand, a lid 10 is removably attached to the upper part of the washing machine main body 1, and the roll brush 5 is provided inside the lid 10.
Fixed brushes 11 are provided in parallel and facing each other.

The fixed brush 11 is a plate body 13 having approximately the same length as the width of the lid body 10.
As shown in FIG. 4, the central part has shorter bristles than both ends, and the central part is curved by a dimension d.

This fixed brush 11 is attached to the inner edge of a lid frame 12 fixed to the upper side of the receiver 4 via a bolt 14 so as to be able to move up and down, and the bolt 14 has a spring 15 that presses the fixed brush 11 downward. It is loaded with bullets.

The lid frame 12 is attached to the inner edge of the washing machine body 1 via bolts 16 so as to be able to move up and down, and the bolts 16 are loaded with springs 17 to constantly press the lid frame 12 downward. .

Furthermore, the fixed brush 11 disposed closest to the inlet 2 is
One end in the width direction is rotatably provided with a hinge 18, while the other end is provided with a stopper 19 so that it can be freely hooked onto the cover body 12, so that it can be rotated around the hinge 18. .

20 is a nozzle that opens on the inlet 2 and outlet 3 sides, respectively;
1 is a pipe that supplies cleaning liquid (water) to the nozzle 20.

22 is an elastic banner made of rubber or the like that covers the outlet 3.

In addition, when cleaning long agricultural products such as radish, both ends of the roll brush 5 and fixed brush 11 are appropriately extended, and brush bristles of the same length as both ends are planted in the extended parts. It is better to make the overall length of the brush longer.

That is, the overall length of the brush is mainly adjusted depending on the crops to be cleaned, and this adjustment is done by adjusting the length of both ends of the brush, not the curved part of each brush. .

Therefore, the operation of the present invention will be explained with reference to the above embodiments.

When agricultural products with soil, such as sweet potatoes, are inputted from the inlet 2 and the roll brushes 5 rotate in the same direction, the sweet potatoes 23 roll between the roll brush 5 and the fixed brush 11 and reach the outlet 3.
move towards.

At this time, cleaning water is ejected from the nozzle 20 to wash away soil, and the roll brush 5 and fixed brush 11 remove soil that cannot be removed by cleaning water alone.

Then, each brush 5
, 11, and the thick part in the center of each brush 5,
The 11 curved parts come into contact with each other and wash away soil evenly.

Therefore, when the sweet potatoes with narrow ends are introduced into the inlet 2, they are introduced parallel to the roll brush 5.

Furthermore, even if sweet potato with a large diameter is thrown in, the fixed brush 11
can move up and down, and the lid frame 12 can also move up and down, so sweet potatoes can be transmitted without being stagnant between the brushes 5 and 11.

In this way, the sweet potato transferred to the outlet 3 is again washed by the jet of washing water from the nozzle 20 and discharged to the outside, and the soil is completely washed away before being discharged.

As described above, according to the present invention, agricultural crops with soil, such as sweet potato, which often have a spindle shape with a large diameter part and a small diameter part, are sandwiched between a roll brush with a curved surface in the center and a fixed brush. , you can evenly remove soil stuck to sweet potatoes.

Moreover, since the fixed brush can be moved up and down, the roll brush can move smoothly even for large-diameter sweet potatoes without causing any stagnation in the transmission.This has the effect of improving the efficiency of cleaning work without causing clogging. be.

Furthermore, by appropriately extending both ends of the roll brush and fixed brush, and planting brush bristles of the same length as both ends in the extended parts to adjust the overall length of the brush, long agricultural products can be cleaned. can also be carried out satisfactorily.
