Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a seedling box cleaning device.

[Conventional technology]

Empty seedling boxes that have been used for raising seedlings have soil and dirt stuck inside them, so they must be washed and cleaned before being stored. -15
As shown in Publication No. 8151, a worker stacks up cleaned seedling growing boxes one after another.

[Problem to be solved by the invention]

However, manually stacking a large number of seedling boxes is labor-intensive and is not very efficient.

An object of the present invention is to save labor and increase efficiency in the cleaning work of seedling boxes.

[Means to solve the problem]

The present invention comprises a loading section that stacks up empty seedling growing boxes after they have been used for raising seedlings, a supply section that delivers out the seedling growing boxes one by one from this loading section, a conveyor that transports the delivered seedling growing boxes along a fixed path, and a conveyor that transports the delivered seedling growing boxes along a certain path. A cleaning section that washes the seedling growing box inside with water, a draining section that removes water adhering to the seedling growing box after washing by blowing air downward, and a stacking section that stacks the seedling growing boxes after draining in a predetermined number of stages in the vertical direction. According to the above structure, if used empty seedling boxes are first stacked on the loading section, empty seedling boxes can be removed from the supply section or the loading section. The seedling growing boxes are fed out one by one, and while the seedling growing boxes are being transferred by a conveyor, they are washed with water by a cleaning section to remove soil, dirt, etc. that have adhered to them.

In the draining section, the air blows downward onto the seedling box after cleaning, so that the adhering moisture can be removed with almost no chance of blown water droplets falling and adhering to the seedling box again. It's coming.

After draining, the seedling boxes are stacked one above the other in the stacking section, so a series of tasks such as cleaning the seedling boxes from the stacking section to the stacking section and setting up before and after cleaning are automatically performed. .

〔Effect of the invention〕

Therefore, we were able to automate the stacking of seedling boxes after cleaning, which was previously done manually, reducing labor and improving cleaning efficiency. Since the water is blown off instantly, the process length of the draining section can be shortened compared to a means of forcibly evaporating using a heater or the like, which has the effect of contributing to the downsizing of the cleaning apparatus.

Further, in this cleaning device, the seedling growing boxes after cleaning are stacked in the stacking section, so there is an advantage that the seedling growing boxes can be easily transported to a subsequent process such as a packing process.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

The drawing shows a nursery box cleaning device. This seedling box cleaning device consists of a loading section (2) that stacks up empty seedling boxes (1) after being used for raising seedlings, and a loading section (2) that stacks the empty seedling boxes (1) from which the empty seedling boxes (1) are stacked.
A supply unit (3) that feeds out seedling boxes (1) one by one, a conveyor (4) that transports the fed out seedling boxes (1) along a fixed path, a washing unit (5) that washes the seedling boxes (1) being transferred with water, and a lower part. A draining section (6) that removes water adhering to the seedling growing box (1) after washing by air blowing toward the container, and a stacking section (7) that stacks the seedling growing boxes after draining in a predetermined number of stages in the vertical direction. As a post-process of the dust cleaning device, an automatic packing section (8) is provided for stringing and packing seedling boxes (1) stacked a predetermined number of stages (10 stages).

The conveyor (4) forms a horizontal transfer path (R) with a large number of idle-rotating or driven conveyor rollers (9), and sequentially transfers the seedling boxes (1) delivered from the supply section (3) to the horizontal transfer path. It is configured to be placed and transported along line (R) toward the accumulation area (7).

The supply part (3) is a device part (3) that supports objects other than the lowest seedling boxes in the loading part (2) formed by stacking the seedling boxes (1) upward by manually feeding them to the starting end of the conveyor (4). The lowermost seedling boxes are sent to the conveyor (4) by a sending device part (not shown) while the seedling boxes (not shown) are released from the stack, and the seedling boxes (
1) are automatically delivered and supplied one box at a time to the conveyance start end of the conveyor (4).

The cleaning section (5) includes a lower nozzle part (10) that sprays water upward from below the conveyor (4) to mainly wash the bottom of the seedling-raising box (1), and a lower nozzle part (10) that sprays water upward from below the conveyor (4) to mainly wash the bottom of the seedling-raising box (1), and a sprayer that sprays water downward from above the conveyor seedling-raising box (1). It is a water jet type consisting of an upper nozzle part (11) which mainly washes the inside of the seedling nursery box (1), and a pump (P) pumps high pressure water to each nozzle part (10),
(11).

In the draining section (6), the seedling raising box (1) is lifted and transferred by an inclined conveyor (12) with the lower side in the conveying direction being upper, and the seedling raising box (1) is placed at a position above the inclined conveyor (12). An injection port (13) that ejects compressed air in an upward direction.

(13) is provided. The rollers (14) of the inclined conveyor (12) are all driven and form an inclined transfer path (W).

These injection ports (13), (13) are arranged below the ejected air and along an inclined direction toward the upper side in the transport direction of the seedling box, and are supplied with compressed air from the air pump (A). Ru.

The accumulating section (7) is made up of a frame (15) arranged below the end of the inclined conveyor (12) in a downwardly inclined position, so that the seedling boxes (1) falling from the end of the inclined conveyor are directed upward. This allows them to be stacked in a predetermined number of stages while maintaining the same posture and with the front and rear ends aligned.

The seedling box (1) is placed on the inclined conveyor (
12), the above-mentioned underframe (15)
) of the conveyor (4) in the cleaning section (6).
It can be set according to the height of the

Then, a predetermined number of rows of seedling boxes (1) stacked on the underframe (15) are carried manually to the automatic packing section (8),
Pack it.

It should be noted that the present invention is not limited to the structure shown in the accompanying drawings by adding numerals in the claims for convenient comparison with the drawings.
