Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method and apparatus for cleaning soiled beans that have been harvested by a combine harvester or the like.

Conventional technology Conventional cleaning of peas uses a double-structured cleaning cylinder consisting of an outer cylinder made of a perforated plate and an inner cylinder whose surface is covered with fluff, and the gap between the outer cylinder and the inner cylinder is It was common practice to supply peas to the washing machine and wash the washing cylinder while rotating it.

Problems to be Solved by the Invention When cleaning using the conventional cleaning cylinder as described above, a phenomenon occurs in which 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. It was hot. Furthermore, since the bean particles floating between the outer cylinder and the inner cylinder are cleaned with fluff, there is a problem in that the entire surface of the bean cannot be thoroughly cleaned without leaking.

An object of the present invention is to solve such conventional problems and provide a method and apparatus for cleaning beans that can be cleaned and finished in a good condition.

Means for Solving the Problems As a means for achieving the above-mentioned object, the first invention, a method for cleaning peas, has a method for cleaning peas on the surface, as can be understood from FIGS. Two cleaning belts 1 having elasticity and liquid retention properties of
2, with the surfaces of both belts 1 and 2 facing each other in parallel and rotating at different speeds,
A characteristic feature is that the pea grains W are pinched and pressed between their surfaces and run while rotating, and both washing belts 1 and 2 are washed with a bath solution at an appropriate position above the rotation and run, and the amount of liquid retained is adjusted. That is.

In addition, the second invention, the pea washing device, has two washing belts 1 and 2 having appropriate elasticity and liquid retention on their surfaces and rotating at different speeds.
In order to pinch the particles W between the surfaces of the belts 1 and 2 and make them run while rotating, the surfaces of the belts 1 and 2 are stretched parallel to each other with their surfaces facing each other in close proximity to each other. , a bath liquid cleaning device 7 and a liquid retention amount adjusting device 8 for both belts 1 and 2 are installed in relation to each other at appropriate positions above the belts 1 and 2.

Function When the beans W are supplied between the two cleaning belts 1 and 2, the beans W travel at a speed equal to the sum of the speeds of the two cleaning belts 1 and 2 divided by 2. Since the surfaces of the cleaning belts 1 and 2 have elasticity, the particles W are wrapped in the surfaces of the cleaning belts 1 and 2 and are appropriately pinched, and furthermore, since the speeds of the cleaning belts 1 and 2 are different from each other, , it runs while rotating. As a result, the entire surface of the peas comes into contact with the surfaces of the cleaning belts 1 and 2 evenly and without leakage, and the peas are thoroughly cleaned and polished.

Further, the surfaces of the cleaning belts 1 and 2 are cleaned by the bath liquid cleaning device 7, and at the same time, the pea grains W
Holds cleaning solution for cleaning. The surfaces of the cleaning belts 1 and 2 are adjusted by a liquid retention amount adjusting device 8 to have a liquid retention amount suitable for cleaning the beans W. As a result, the surfaces of the cleaning belts 1 and 2 are always washed clean and the beans W are always kept clean, and the surfaces of the cleaning belts 1 and 2 always keep an appropriate amount of cleaning liquid and the dirt from the beans W is always wiped clean. Note that the amount of liquid retained on the surfaces of the cleaning belts 1 and 2 must be adjusted to an appropriate amount, since if this amount is too large, wrinkles will occur on the skin of the beans W, resulting in deterioration of quality.

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

1 to 3 show a first embodiment.
1 and 2 are flat endless cleaning belts, and the outer material (surface material) 1 is made of slightly stiff sponge or nonwoven fabric.
a, 2a are attached to strong linings 1b, 2b, which have the appropriate elasticity to wrap around half a bean W, and the appropriate elasticity to absorb a small amount of cleaning liquid such as water or an aqueous alcohol solution. It has liquid retention properties. In addition to the first embodiment described above, the cleaning belts 1 and 2 have a structure in which the outer material is made of cotton wool or synthetic resin hair (like artificial grass) and the lining is made of fluff (motsupu) or synthetic resin hair (like artificial grass). It is also possible to have hair transplanted on the surface.

In addition, the cleaning belts 1 and 2 have their surfaces (outer material 1
upper rolls 3, which are arranged in two tiers in the horizontal direction, with the rolls a and 2a) facing each other in parallel (with a distance of about 2 to 4 mm);
3 and the lower rolls 4, 4 are provided with tension racks in parallel. The cleaning belts 1 and 2 are formed horizontally as described above, but may also be vertically or inclined.

The cleaning belts 1 and 2 are designed to be electrically conductive so as to rotate at different speeds. The rotational running directions of the cleaning belts 1 and 2 do not necessarily have to be the same.

Reference numeral 5 denotes a meandering path for causing the peas W to meander between the surfaces of the cleaning belts 1 and 2. A guide body 6, which is a round or square rod bent in the width direction of the cleaning belts 1 and 2, is moved in the width direction of the cleaning belts 1 and 2. The cleaning belts 1 and 2 are formed by being fitted between the surfaces of the cleaning belts 1 and 2 at equal intervals (to the extent that 1 to 3 peas W are present).

7 is a bath liquid cleaning device for cleaning the surfaces of the cleaning belts 1 and 2, and a shower 7a is provided on the return travel side of the cleaning belts 1 and 2 to spray a cleaning liquid such as water or an aqueous alcohol solution. There is.

Reference numeral 8 denotes a liquid retention amount adjusting device for appropriately adjusting the amount of liquid retained (content of cleaning liquid) on the surfaces of the cleaning belts 1 and 2. A vacuum 8a is provided next to the shower 7a, and the cleaning belts 1 and 2 are It is designed to absorb a moderate amount of cleaning liquid contained on the surface.

In the figure, reference numeral 9 is a machine frame, 10 is a supply hopper, and 11 is a discharge gutter.

FIG. 5 shows a second embodiment. This is basically the same as the first embodiment described above, and the only difference is that a rotary brush 7b that sprays cleaning liquid and a bath tank 7c are used as the bath liquid cleaning device 7, and A case is illustrated in which a plate-shaped scraper 8b and a squeezing roll 8c are used as the liquid amount adjusting device 8.

Here, the cleaning action of beans will be explained.

Washing belts 1 and 2 are supplied with beans W from the hopper 10.
When supplied between the washing belts 1 and 2, the peas W are wrapped around the surfaces of the washing belts 1 and 2, are appropriately pinched, and run while rotating. Moreover, the beans W meander around the meandering path 5 while rotating in various directions.
Thus, the peas W are washed and polished while running between the surfaces of the cleaning belts 1 and 2, and are discharged from the discharge gutter 11.

In addition, the surfaces of the cleaning belts 1 and 2 that are soiled by cleaning the peas W are washed by being sprayed with a cleaning liquid by the bath liquid cleaning device 7, and the amount of the cleaning liquid absorbed at that time is transferred to the next liquid reservoir. The amount is adjusted appropriately by the amount adjusting device 8. Therefore, the peas W are always cleaned and polished by the surfaces of the cleaning belts 1 and 2, which are always clean and appropriately moist.

Effects of the Invention As described above, the present invention wraps the peas W between the surfaces of the two cleaning belts 1 and 2, applies appropriate pressure to them, and runs them while rotating to clean them. Not only is there no cracking of the body of the bean W and damage to the surface of the bean W, but also the entire surface of the bean W can be uniformly and thoroughly washed, resulting in the effect of finishing the bean W in a good condition.

In addition, the present invention is provided with a bath liquid cleaning device 7 and a liquid retention amount adjusting device 8 to constantly wash the cleaning belts 1 and 2 and keep the liquid appropriately retained. It has the effect of cleaning and staining even more cleanly.

Furthermore, as in this embodiment, if the meandering path 5 is formed to cause the beans W to travel in a meandering manner, the beans W can be rotated in various directions, and the cleaning belts 1 and 2 can be moved over a limited short distance. It is possible to run for a longer time while detouring within the distance, and the
Cleans and stains even more effectively.
