Description

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

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 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. 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 object, the pea washing device of the present invention has a surface with appropriate elasticity and liquid retention, as can be understood from FIG. 1 showing an embodiment thereof. The surfaces of two cleaning belts 1 and 2, which have a characteristic of The cleaning belts 1 and 2 are installed in parallel in parallel and close to each other in a stretched manner.
A solution cleaning device 7 and a liquid retention amount adjusting device 10 for the belts 1 and 2 are installed in relation to each other at appropriate positions above the rotational distance of the cleaning belts 1 and 2. It is configured to be able to approach and separate from the surface of the aircraft body A, and an operating section B that controls the approach and separation drive is provided on the outside of the aircraft body A.
It is characterized by having the following.

Function When the beans W are supplied between the two cleaning belts 1 and 2, the beans W travel at a speed that is 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 beans comes into contact with the surfaces of the cleaning belts 1 and 2 evenly and without leakage, and is 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 10 to have a liquid retention amount suitable for cleaning the beans W. The amount of liquid retained on the surface of the cleaning belts 1 and 2 should be kept at an appropriate amount, as if this amount is too large, wrinkles may occur on the skin of the beans W, or the skin may be torn, resulting in a deterioration in quality. must be adjusted to. As a result, the surfaces of the cleaning belts 1 and 2 are constantly soaked in the washing to keep the beans W cleanly cleaned, and the surfaces always retain an appropriate amount of cleaning liquid to always wipe off dirt from the beans W.

In the process of cleaning such peas W, when the cleaning operation is finished or interrupted and the rotation of the cleaning belts 1 and 2 is stopped, operate the operation part B to adjust the liquid retention amount adjusting device 10 of the cleaning belts 1 and 2. Try to keep it away from the surface. In this way, it is possible to prevent the surface elasticity of the cleaning belts 1 and 2 from deteriorating.
The cleaning function of the cleaning belts 1 and 2 can be maintained for a long period of time. If the liquid retention amount adjusting device 10 continues to be in contact with the surfaces of the cleaning belts 1 and 2 while they are stopped, the contact portions of the surfaces of the cleaning belts 1 and 2 will be locally compressed and dented, and the elasticity will deteriorate. Therefore, while the cleaning belts 1 and 2 are stopped, the liquid retention amount adjusting device 10 must be kept away from the surfaces of the cleaning belts 1 and 2. In addition, when the cleaning operation is started again and the cleaning belts 1 and 2 are rotated, all that is required is to operate the operation part B to bring the liquid retention amount adjusting device 10 into contact with the surface of the cleaning belts 1 and 2. .

Embodiments Examples of the present invention will be specifically described with reference to the drawings. A is the body of the cleaning device.

It has the appropriate elasticity to enclose about half a grain, and the appropriate liquid retention ability to absorb a small amount of cleaning liquid such as water or an aqueous alcohol solution.

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 driven by a motor M via a chain C so that they rotate at different speeds. In addition, the cleaning belts 1 and 2
The rotational running directions of the two do not necessarily have to be the same. Furthermore, the cleaning belts 1 and 2 may be formed horizontally as described above, but may also be vertically or inclined.

Reference numeral 5 denotes a meandering path through which the peas W are run meandering between the surfaces of the cleaning belts 1 and 2, and a guide body 6 formed by bending a round or square rod in the width direction of the cleaning belts 1 and 2 is moved in the coaxial direction. 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 can fit in).

Reference numeral 7 denotes a bath liquid cleaning device for cleaning the surfaces of the cleaning belts 1 and 2, which includes a cleaning brush 8 that rotates in contact with the surface of each cleaning belt 1 and 2, and a cleaning liquid such as water or an aqueous alcohol solution applied to the brush 8. It consists of a liquid supply pipe 9 that injects liquid. The cleaning brush 8 is connected to the upper and lower rolls 3, 4 via the chain C by the motor M.
It is designed to be rotated together with the rotor. The liquid supply pipe 9 is opened and closed by an electromagnetic on-off valve V.

Reference numeral 10 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, and includes a squeezing roll that rotates in pressure contact with the surface of each cleaning belt 1 and 2. 11 as the bath liquid cleaning device 7
It is set up in two stages next to. The squeezing roll 11 on the side of the cleaning belt 2 presses and clamps the cleaning belt 2 against a supporting roll 12 at a fixed position paired with the squeezing roll 11 to adjust the amount of liquid retained. In the squeezing roll 11 on the cleaning belt 1 side, the upper roll 3 serves as a supporting roll. Note that the liquid retention amount adjusting device 10 may include a scraping plate (scraper) instead of the squeezing roll 11.

The bracket 13 is configured to move up and down. Further, the operating lever 14 is electrically connected to the motor M and the electromagnetic on-off valve V via a limit switch 18, and the limit switch 18 is configured to open and close by vertically moving the operating lever 14. . Thus, the operation section B controls the vertical movement of the bracket 13 (driving the bath liquid cleaning device 7 toward and away from the surface of the cleaning belts 1 and 2 with the liquid retention amount adjustment device 10 and the liquid retention amount adjustment action), and the limit switch 18. Opening/closing (rotation driving of the cleaning belts 1 and 2 and bath liquid cleaning action) is performed by a single operating lever 14.
It is structured so that it is controlled and linked with. Note that the operating section B is the operating lever 14 as in this embodiment.
However, the present invention is not limited to the present invention, and it is also possible to use a push button switch, an electric device, or the like.

In the figure, reference numeral 19 is a supply hopper for the beans W, and 20 is a discharge gutter for the beans W.

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

First, when the operating lever 14 is moved upward, the limit switch 18 is closed, the motor M is rotated, the upper and lower rolls 3 and 4 are rotated, and the cleaning belts 1 and 2 are rotated and run. At the same time, the cleaning brush 8 rotates, and the electromagnetic on-off valve V opens to inject cleaning liquid from the liquid supply pipe 9 to the cleaning brush 8. At the same time, the bracket 13 moves upward, and the cleaning brush 8 and squeezing roll 11 are urged by the compression spring 17 and come into pressure contact with the surfaces of the cleaning belts 1 and 2. In this way, the surfaces of the cleaning belts 1 and 2 are cleaned with the solution, the amount of liquid retained is adjusted, and a system for cleaning the beans W is prepared. Here, when the peas W are supplied between the cleaning belts 1 and 2 from the supply hopper 19, the peas W are delivered to the meandering path 5.
The cleaning belts enter the interior of the cleaning belts 1 and 2, are deeply wrapped in the surfaces of the cleaning belts 1 and 2, are appropriately clamped, and run while rotating (see Fig. 3). Moreover, the beans W meander through the meandering path 5 while rotating in various directions (see FIG. 4). While the beans W stably travel on a predetermined course, their entire surfaces come into contact with the surfaces of the cleaning belts 1 and 2 evenly and without leakage, and are thoroughly cleaned and polished before being discharged from the discharge gutter 20. Ru.

In addition, the surfaces of the cleaning belts 1 and 2, which have been soiled by cleaning the peas W, are brush-cleaned by being bathed in the cleaning liquid by the bath liquid cleaning device 7 as described above, and the amount of the cleaning liquid absorbed at that time is The liquid retention amount is adjusted appropriately by the liquid retention amount adjusting device 10. However, beans W
are constantly cleaned and polished by the surfaces of the cleaning belts 1 and 2, which are always clean and appropriately moist.

To finish cleaning the beans W, move the operating lever 14 downward, the limit switch 18 opens, the motor M stops rotating, and the cleaning belt 1,
2 also stops rotating. At the same time, the cleaning brush 8
stops rotating, and the electromagnetic on-off valve V closes to stop spraying the cleaning liquid. At the same time, the bracket 13 moves downward, and the cleaning brush 8 and squeezing roll 11
and separates from the cleaning belts 1 and 2.

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 chance of cracking the body of the bean W or damage to the surface of the bean W, but the entire surface of the bean W can be cleaned and polished evenly and without leaking.
It has the effect of finishing the product in good condition.

In addition, the present invention is provided with the bath liquid cleaning device 7 and the liquid retention amount adjusting device 10 to constantly wash the cleaning belts 1 and 2 and keep the liquid appropriately retained, so that the peas W can be kept for a long time. Particularly, in the present invention, the liquid retention amount adjusting device 10 is controlled by the cleaning belt 1, the cleaning belt 1,
Since it is designed so that it can be easily separated from the surface of the cleaning belts 1 and 2, when the cleaning operation is completed or interrupted and the rotation of the cleaning belts 1 and 2 is stopped, the liquid retention amount adjusting device 10 is removed from the surface of the cleaning belts 1 and 2. By moving the cleaning belts 1, 2 away from the surfaces of the cleaning belts 1, 2, elastic deterioration of the surfaces of the cleaning belts 1, 2 can be prevented.
It has the excellent effect of extending the life of the product.

Note that, as in this embodiment, the liquid retention amount adjusting device 10
By linking the approaching and separating drive with the rotating drive of the cleaning belts 1 and 2, there is no need to operate both drives separately, and when the cleaning belts 1 and 2 are stopped, the liquid retention amount adjusting device 10 This has the effect of ensuring that people leave.

In addition, as in this embodiment, if not only the liquid retention amount adjusting device 10 but also the bath liquid cleaning device 7 is driven toward and away from the surfaces of the cleaning belts 1 and 2, the same effect as described above can be obtained. It becomes even more convenient.
