Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention stores and stores fresh leaves picked from tea fields and collected at a tea factory, and automatically transfers them to a processing line in appropriate amounts according to the processing capacity of the tea factory. The present invention relates to a feeding device.

[Conventional technology]

Generally, the picked fresh tea leaves are stored in a fresh leaf room equipped with a ventilated floor. Then, the fresh leaves are carried into the fresh leaf room and are sprayed and stored on the ventilated floor surface either manually or by a scattering device installed on the ceiling of the fresh leaf room.

In the case of the above method, it is necessary to dig a pit in the floor surface in order to construct a ventilated floor surface, and it is necessary to construct a special structure of the building in order to install the spraying device on the ceiling. Therefore, there is a problem that a large amount of construction cost and construction period is required, and the installation location of the device is fixed and cannot be moved.

There is a device shown in Japanese Utility Model Publication No. 58-23227 that has solved the above-mentioned problems to some extent, but this device has a fresh leaf input device only at the receiving end of the permeable conveyor, teeth,
It is supposed to be supplied from the receiving end which is the rear end of the air permeable conveyor.

[Problem to be solved by the invention]

By the way, according to the conventional device, when the fresh leaves have been received, for example, about half into the air-permeable conveyor, the fresh leaves have not yet reached the delivery end of the conveyor, so it is impossible to feed the fresh leaves to the processing line. It is possible, therefore, that the feeding of green leaves to the processing line will only begin after the green leaves on said conveyor have reached their delivery end.

Due to the above-mentioned circumstances, it usually takes about 5 to 6 hours to start supplying fresh leaves to the processing line, depending on the collection situation of fresh leaves, and this time depends on the length and storage capacity of the conveyor mentioned above. There is a problem that the larger the size, the longer it becomes. The above-mentioned problem is serious because tea manufacturing is a seasonal industry, and tea factories, where work is concentrated at one time, want to start processing work as soon as possible.

In addition, once the feeding of fresh leaves to the processing line begins, the receiving speed is generally 4 to 5 times the sending speed, so the speed of the permeable conveyor during sending out and the speed when receiving fresh leaves are Because of the difference in speed as mentioned above, there is a problem that fresh leaves cannot be received onto the aerated conveyor until the sending operation is completely completed. Even if fresh leaves are received in small quantities in accordance with the delivery speed, as shown in FIG. Therefore, there is a problem that not only the efficiency of storing fresh leaves on the conveyor becomes extremely poor, but also the processing efficiency of the entire tea factory may be extremely reduced.

An object of the present invention is to provide an automatic tea leaf storage device that solves the above-mentioned problems.

[Means to solve the problem]

In order to achieve the above-mentioned object, the automatic tea leaf storage device according to the present invention has a long tea leaf leaf, which has one end as a delivery end, is provided with a cutting device at the delivery end, and is connected to a processing line by a transportation device. In a wide conveyor-type automatic green tea leaf storage device, the storage floor is made up of a breathable endless conveyor belt, which allows ventilation from the bottom surface, and the green tea leaves are fed from an input device to the upper part of the storage device, and Its feature is that it is equipped with a scattering conveyor that uniformly spreads green tea leaves over almost the entire width and length of the device while moving from side to side.
