Description

[Detailed explanation of the invention] (a) Technical field of the invention This invention relates to a cleaning device used to wash fruits such as pumpkins, and more specifically, to an automatic cleaning device that sequentially and continuously cleans the surface of the fruit. The present invention relates to a fruit cleaning and processing device that can be used to clean fruits.

(b) Background of the invention The current method of cleaning pumpkins and the like involves workers washing each pumpkin with water and brushing it with a brush.

However, with such a cleaning method, all of the harvested fruits must be washed manually, which is time-consuming and requires a lot of labor. In particular, when it comes to fruits with highly uneven surfaces, such as pumpkins, it takes a lot of time to remove sand, dirt, and other substances adhering to the surface.

(c) Purpose of the invention Therefore, the purpose of this invention is to provide a fruit cleaning device that can automatically wash fruits without having to do it manually.

(d) Summary of the invention This invention consists of a lower conveyor brush for conveying fruits in which a large number of rotating brushes are arranged in series to revolve around each other like a conveyor, and a brush that faces both sides of the lower conveyor brush to clean the sides of the fruit. The fruit washing processing device includes side rotating brushes arranged opposite to each other, and a plurality of upper rotating brushes arranged in parallel in the fruit conveyance direction, which are vertically movably provided above between the side brushes and rotate in the horizontal direction. It is characterized by

(e) Effects of the invention According to this invention, just by feeding fruits into this device, the fruits are automatically cleaned by the cleaning power of the bottom conveyor brush and the side rotating brush.

In particular, since the fruit is washed while being rolled by the rotating operation of the lower conveyor brush, even if the fruit is a highly uneven fruit such as a pumpkin, every corner of the outer surface of the fruit is reliably washed.

Moreover, the fruit is automatically transferred to the next stage after cleaning is completed by the bottom conveyor brush.
For example, if this device is installed in a fruit sorting line that sorts fruit by size, it will be possible to wash, transport, and sort the fruit during the transport stage, and achieve complete automation of the process of harvested fruit up to shipping. be able to.

In addition, this device is equipped with a plurality of upper surface rotating brushes arranged in parallel in the fruit conveying direction that rotate in the horizontal direction, so that while the fruit is being conveyed by the lower surface conveyor brush, the fruits are continuously successively passed from the upper surface to the succeeding surface. Cleaning is done using a rotating brush, which further improves the cleaning effect, and since the top rotating brush is movable up and down, it can be used to clean all types of fruit, from large berries and melons to mandarin oranges and apples. Applicable to cleaning.

(F) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The drawing shows a fruit washing processing device, and as shown in FIGS. 1 to 3, this device 1 is disposed before and after a fruit conveying line to wash and wash the harvested fruits. The fruit is sequentially conveyed to the next stage processing section, and the structure includes a lower conveyor brush 2, a side rotating brush 3, an upper rotating brush 4, and a water injection device 5.

The above-mentioned lower conveyor brush 2 has a large number of cylindrical rotating brushes 6 arranged in series so as to revolve like a horizontal conveyor. The parallel shaft portions of the rotating shafts 7 protruding outward from the rotating brushes 6 are connected by a chain 8 to form a horizontally long loop, and the conveyor reversing portion of the chain 8 A driving sprocket 9 is disposed on one side of the chain 8, and a driven sprocket 10 is disposed on the other side to support the chain 8 in a drivable manner.

Further, rollers 11 for rotating the rotating brushes are integrally fitted onto these rotating shafts 7, and these rollers 11 are supported and guided by rails 12 installed along a loop-shaped conveyor and are moved by rolling. , the rotating brushes 6, . . . are provided as one conveyor of a conveyor so that they can be rotated and transported in a circular motion, and are driven by a conveyor drive device, which will be described later. Note that a chain 8 and a rail 12 are disposed on both sides of the rotating shafts 7, 7 of the rotating brushes 6, respectively.

The above-mentioned conveyor drive device 13 rotates a series of rotating brushes 6 via the chain 8 by driving the above-mentioned drive sprocket 9 via a motor 14 and a deceleration mechanism 15. The power is driven by drive sprocket 9.
As a result, the rotating brushes 6 are transferred in the horizontal direction. At this time, the rollers 11 of the rotating brushes 6 slide on the rails 12, so the rotating brushes 6 are rotated and the chain 8 is transferred. It is rotated along with.

The above-mentioned side rotating brushes 3 are installed opposite to each other on both sides of the lower conveyor brush 2 to clean the side surfaces of the fruit. Rotating brushes 16, 16 are horizontally installed facing each other.

The long rotary brushes 16 have their rotary shafts 17 connected to deceleration mechanisms (not shown) via motors (not shown), and are set at a predetermined rotational speed and in the same direction of rotation, and are rotated onto the lower conveyor brush 2. Its role is to rotate and transport the fruits being transported. This enhances the cleaning effect on the fruit.

In this case, the spacing between the rotating side brushes 3, 3 may be adjusted as appropriate depending on the size of the fruit.

The above-mentioned upper rotating brush 4 is provided with a plurality of circular rotating brushes 18 vertically installed on the upper surface in the longitudinal direction of the lower conveyor brush 2 and rotating horizontally at regular intervals to clean the upper surface of the fruits on the conveyor. A rotating shaft 19 protruding from the upper surface of these brushes 18 is attached to a support 20 horizontally suspended above the conveyor.
A driven gear 21 is fixed to the upper end of these rotating shafts, and is engaged with a driving gear 24 that is integrated with a drive shaft 23 that is rotatably suspended horizontally via a drive device 22. The rotating brush 18 is rotationally driven.

In addition, this upper rotating brush 4 is connected to the lifting adjustment device 2.
5, which adjusts the height of the brush up and down according to the size of the fruit, and the entire support member 26 that supports the upper rotating brush support 20 is synchronously operated from below in a pair of left and right directions. The height is adjusted by moving up and down with hydraulic cylinders 27, 27.

The water injection device 5 described above injects water through the supply pipe 28 at appropriate intervals along the longitudinal direction of the lower conveyor brush 2 so that water can be sprayed from the diagonally upper gap between the side rotating brushes 3, 3 and the upper rotating brush 4. A nozzle 29 is supported and installed on a support body 20.

When cleaning fruits such as pumpkins using the fruit cleaning apparatus configured as described above, first, the upper, lower, left, and right brushes 4, 2, 3, and 3 are rotated, and the fruit 30 is cleaned from the bottom side. Insert from the starting end side of the conveyor brush 2.

Then, the loaded fruit 30 is transferred in the conveying direction while its lower surface is cleaned by the rotating action of the lower conveyor brush 2, and its side surfaces are also rotated in the lateral direction by the left and right side rotating brushes 3, 3. The upper surface is washed while being repeatedly rotated in the horizontal rotation direction by a plurality of continuous rotating brushes 18 forming the upper surface rotating brush 4.

In addition to the cleaning action of each of these brushes 2, 3, 3, and 4 in different rotational directions, the water injection device 5
The fruit 30 is thoroughly cleaned on its entire outer circumferential surface by the washing action of the water spray, and the automatic washing of the fruit is completed. Then, it is sequentially conveyed from the terminal end side of the lower conveyor brush 2 to the rear stage.

Note that an input chute (not shown) is appropriately provided at the starting end of the bottom conveyor brush, and a discharge chute (not shown) for leading to the subsequent stage is provided at the terminal end.
