Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for collecting a sample for evaluating the grade of fresh tea leaves when collecting fresh tea leaves collected from a tea field at a factory.

[0002]

2. Description of the Related Art Fresh tea leaves brought into a crude tea factory by each farmer are first collected in a container for receiving fresh leaves. At that time, a part of the fresh tea leaves that are brought in will be sampled, and an examination will be conducted to make a rating according to the grade, and the price of the fresh tea leaves will be determined by the grade. Each time, a worker manually takes a sample from the tea-cutting bag and places it in a sample box. However, sometimes all the tea leaves are put into the raw leaf receiving container before the sample is taken, and at that time, the worker enters the raw leaf receiving container and puts it in the raw leaf receiving container. The raw tea leaves that are put in are collected by hand. In the past, all was manual work, and there was no device for automatically sampling fresh tea leaves.

[0003]

In the conventional sample collection, if all the tea leaves are put into the raw leaf receiving container before the sample is taken, the worker enters the raw leaf receiving container. However, the container for receiving fresh leaves has a depth of about 2 m, it is very difficult to get in and out, and the bottom surface is formed by an endless transportation zone, and fresh tea leaves are thrown in one after another. It is a danger. Further, after being put in the fresh leaf receiving container, the fresh tea leaves of other tea gardens are mixed and it is difficult to distinguish them. Further, when a worker enters the fresh leaf receiving container, the fresh tea leaf in the fresh leaf receiving container may be trampled, which may damage the fresh tea leaf.

Even if a sample is taken at the place of introduction before the introduction of fresh tea leaves, when many fresh tea leaves are introduced in one day, it is a great labor to collect them manually.
In addition, when collected by a worker, only good leaves or bad leaves may be collected, and the evaluation changes depending on the tea leaves to be collected.

It is an object of the present invention to provide a device capable of automatically sampling all fresh tea leaves brought into a factory without the need for an operator to stand.

[0006]

In order to achieve the above object, in the sampling apparatus of the present invention, a container for receiving fresh leaves buried in the floor surface can be formed by a belt conveyor having a length substantially in the depth direction of the container. One end of the sample conveyor is attached to the wall of the container for receiving fresh leaves below the floor surface, and the other end is placed on the opposite surface of the sample box for storing fresh tea leaves for sample. Take the means of erection while looking into.

[0007]

By inserting fresh tea leaves on the sampling conveyor configured as described above, the fresh tea leaves on the sampling conveyor are transferred and collected in the sample box. Sample tea leaves are sent one after another, and when more tea leaves are sent than the sample box, excess tea leaves overflow the sample box and are returned to the container for receiving leaves. or,
The fresh tea leaves that did not lie on the sampling conveyor were lumped in the tea-cutting bag, but they hit the sampling conveyor and were loosened. Furthermore, since the sampling conveyor and the sample box are all visible, it is easy to confirm that they are being sampled accurately.

[0008]

EXAMPLES Examples will be described with reference to the drawings. Fresh tea leaves that have been plucked in a tea garden are put in a tea-cutting bag 1 and transported by a truck 2 to a tea factory. A pit 3 having a depth of 2 m, a depth of 3 m, and a width of 5 m is dug in a fresh leaf receiving place of a tea manufacturing factory, and a fresh leaf receiving container 5 having a bottom surface constituted by an endless transportation zone 4 is buried. This fresh leaf receiving container 5 is a container for collecting and receiving fresh tea leaves brought in from each farm.

In the figure, the side on which the truck is located is the loading side of the fresh leaf receiving container 5. In this embodiment, the sampling conveyor 8 has a length of 3.5 m and a belt width of 20 cm.
As shown in FIG. 1, one end of the sample box 7 is attached to the upper end of the raw leaf receiving container 5 on the input wall side, and the other end is placed on the floor opposite to the input port of the raw leaf receiving container 5. It is constructed so that it can be seen. The sampling conveyor 8 rotates in the direction in which the fresh tea leaves 10 are sent to the sample box 7. The sample box 7 is made of resin and has a length of 30 cm, width of 20 cm, and height of 15
I am using a cm one.

The fresh tea leaves 10 are put into the fresh leaf receiving container 5 by the person who brought them in. At this time, 10 fresh tea leaves
So that the fresh tea leaves 10 are placed on the sampling conveyor 8,
Open the tea-cutting bag 1. The fresh tea leaves 10 on the sampling conveyor 8 are transferred as they are and put into the sample box 7.
Further, the sample box 7 is supported by the arm, and the floor surface 6 is configured obliquely, so that the fresh tea leaves 10 overflowing from the sample box 7
Are returned to the fresh leaf receiving container 5.

The fresh tea leaves 10 that did not reach the sampling conveyor 8 fall directly and are fed into the fresh leaf receiving container 5
Be thrown into. At this time, the fresh tea leaf 10 hits the sampling conveyor 8 and is divided into left and right parts to loosen the lump.

The green tea leaves 10 put into the fresh leaf receiving container 5 are moved to the delivery end by the endless transportation belt 4, and are sent by the scraping device 12 to the transport conveyor 11 in fixed amounts, and by the transport conveyor 11. The tea leaves are transferred to a tea leaves management container (not shown) for storing the tea leaves.

[0013]

Since the present invention is constructed as described above, it has the following effects. The operator can take a sample from the tea-cutting bag or perform sampling without entering the container for receiving fresh leaves, so that the burden on the operator can be reduced. There is also no risk of trampling fresh tea leaves in the fresh leaf receiving container. Since the fresh tea leaves can be uniformly sampled from all tea cutting bags, the reliability of sampling is improved.

Since the fresh tea leaves on the sampling conveyor can be easily confirmed by the operator, the sample does not mix. Furthermore, since a large amount of fresh tea leaves were brought from the tea garden at one time, the fresh tea leaves were lumped and steamed, but the sampling conveyor conveys the lumps to loosen the lumps, making it easier to remove hot air and maintaining the quality of the fresh tea leaves. To be done.
