Abstract

PURPOSE:To obtain a cleaning apparatus for bean grains capable of cleaning bean grains without applying damage to the grains, by oppositely disposing a drum and a belt each having elastic surface interposing a particular guide member therebetween and rotating and transferring both elements at different speeds. CONSTITUTION:A belt 4 produced by laminating an elastic surface material 6 to a high-modulus backing substrate 5 is placed opposite to a drum 1 produced by lining an elastic surface material 3 on the surface of a rotary drum 2 interposing a guide member 11 between the belt and the drum. The belt 4 and the drum 1 are rotated at different surface speeds. The guide member 11 is provided with grooves 10 directed slant to the circumference of the drum 1 and having a thickness slightly smaller than the size of the bean grain. A cleaning brush 16 and a wafer-feeding apparatus 17 are provided in order to apply water to the surface of the belt 4 while cleaning the surface.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for cleaning soiled beans harvested by a combine harvester, etc., and a packaging thereof.

Conventional technology Conventionally, peas are washed using a double-structured cleaning cylinder consisting of an outer part made of a perforated plate and an inner part whose surface is covered with cotton wool. It was common to supply peas and wash the washing cylinder while rotating it.

Problems to be Solved by the Invention When cleaning using the above-mentioned conventional cleaning cylinder, there is a problem in that the fluff of the inner cylinder hits the beans against the outer cylinder, resulting in cracking of the beans and damage to the surface of the beans. was there. Also,
Since the peas floating between the outer cylinder and the inner cylinder are washed with fluff, there is also the problem that the entire surface of the peas cannot be thoroughly cleaned without leaking.

An object of the present invention is to solve such conventional problems and provide a bean cleaning device that cleans and finishes beans in a good condition.

Means for Solving the Problems As a means for achieving the above object, the pea washing device of the present invention has a surface having appropriate elasticity, as can be understood from FIG. 1 showing an embodiment thereof. The cleaning drum (1) rotates at a speed similar to that of the cleaning drum (1), and the cleaning belt (1), which has a suitable elasticity on its surface and rotates at a speed different from that of the cleaning drum (1), is attached to the cleaning drum (1).
4) is rolled and stretched with the surfaces facing each other in order to sandwich the grain (W>) between the surfaces of <1.4) and run it on an incline while rotating. It is characterized in that a diagonal path (10...) is formed in the.

A bean (W) is placed between the action cleaning drum (1) and the cleaning belt (4).
), the peas (W) travel at a speed equal to the sum of the speeds of the washing drum (1) and the washing belt (4) divided by 2. Furthermore, since the surfaces of the cleaning drum (1) and the cleaning belt (4) have elasticity, the peas (W) are wrapped in the surfaces of the cleaning drum (1) and the cleaning belt (4), and are appropriately compressed.
Since the speeds of 1) and the cleaning belt (4) are different from each other,
It travels while rotating, and furthermore, since the oblique path (10...) is formed, it travels at an incline while rotating in various directions (the rotational direction and the width direction of the cleaning drum).

As a result, the surface rest of the beans (W>) contacts the surfaces of the cleaning drum (1) and the cleaning belt (4) uniformly and without leakage.
Cleaned and polished. .

Example Embodiments of the present invention will be specifically described with reference to the drawings.

Reference numeral 1 denotes a cleaning drum, which has a cleaning surface material 3 attached to the circumferential surface of a rotary drum 2. 4 is a flat endless cleaning belt,
A cleaning surface material 6 is attached to a strong lining 5. This cleaning surface material 3.6 is made of a sponge or non-woven fabric with a slightly molded opening, and has moderate elasticity to wrap around a pea grain W by about the size of a hand, and a small amount of cleaning liquid such as water or alcohol solution.
It has a moderate liquid retention property that can be sucked.

The cleaning belt 4 is placed in a state in which the surfaces of the belt 4 and the cleaning drum 1 are opposed to each other, and the cleaning belt 4 is attached to the cleaning drum 1 by about 100 mm.
It is wound around the roll 7.8.9 and stretched for 3 turns. The cleaning drum 1 and the cleaning belt 4 are driven by a motor (not shown) so that they rotate at different speeds. ! ! 11 疋汀Ga times are exactly the same -(na(-(b good.

Reference numeral 10 denotes a diagonal path for causing the grains W to run at an angle between the surfaces of the cleaning drum 1 and the cleaning belt 4. The washing drum 1 and the washing belt 4 are formed by being fitted in an inclined manner between the surfaces of the washing drum 1 and the washing belt 4 at equal intervals in the width direction (approximately 1 to 3 peas W can fit therein).

Reference numeral 12 denotes a bath liquid cleaning device for cleaning the surface of the cleaning drum 1, which includes a cleaning brush 13 that rotates in contact with the surface of the cleaning drum 1, and a liquid supply that sprays a cleaning liquid such as water or an aqueous alcohol solution onto the brush 13. It consists of a pipe 14. Reference numeral 15 denotes a bath liquid cleaning device for cleaning the surface of the cleaning belt 4, which also includes a cleaning brush 16 and a liquid supply pipe 17.

18 is the liquid retention a<cleaning liquid content m) on the surface of the cleaning drum 1
This is a liquid retaining fine adjustment device for appropriately adjusting the amount of water, and consists of a squeezing roll that rotates while pressing against the surface of the cleaning drum 1.

Reference numeral 19 denotes a liquid retention adjustment device for dividing the liquid retention property of the surface of the cleaning belt 4 into two sections, which also consists of a squeezing roll.

In addition, the code|symbol 20 in the figure is the said washing equipment; a machine frame of α, 21 is the supply hopper of the beans W, 22 is the feeding roll of the beans W, and 2
3 is a drain gutter for the beans W, and 24 is a drain gutter for the cleaning liquid.

Here, the cleaning action of peas based on Examples will be explained.

When the peas W are supplied from the supply hopper 21 to the gate between the cleaning drum 1 and the cleaning belt 4, the peas W are wrapped in both surfaces and are appropriately compressed and run while rotating (see FIG. 3). Moreover, the peas W run along the inclined path 10 while rotating in various directions (the rotational direction and the width direction of the cleaning drum 1) (see FIG. 4). However, the bean W is
While running stably on a predetermined course, the entire surface of the cleaning drum 1 and the cleaning belt 4 come into contact with the surfaces of the cleaning drum 1 and the cleaning belt 4 evenly and without leakage, and are thoroughly cleaned and polished before being discharged from the discharge gutter 23. Furthermore, the surfaces of the cleaning drum 1 and the cleaning belt 4, which are contaminated by cleaning the beans W, are cleaned by the bath liquid cleaning device 111.
12.15, the cleaning liquid is washed with a brush, and the amount of the cleaning liquid sucked up at that time is appropriately adjusted by the next liquid holding device 18.19. Therefore, the beans W are always cleanly cleaned and polished by the surfaces of the cleaning drum 1 and the cleaning belt 4, which are always clean and appropriately moist.

Effects of the Invention As mentioned above, the present invention provides a washing drum (1) for washing peas (W>).
The washing belt (4) is wrapped around the surface of the bean and the cleaning belt (4), is pressed appropriately, and is run while rotating for cleaning.
The entire surface of the bean grain (W) can be uniformly and thoroughly cleaned and polished without any loss of a, which has the effect of finishing the bean grain (W>) in a good condition.

In particular, in the present invention, the peas (W>) run on the circumferential surface of the cleaning drum (1) and also run at an inclination, so the peas (W>) are small compared to the overall size of the device. It is possible to shape the travel distance of the
can be rotated in various directions, which has the excellent effect of further increasing the cleaning performance of peas (W).
