  In order to remove fine cut leaves, it was necessary to install a device for removing fine cut leaves, which required equipment costs and space. In addition, it was necessary to dispose of garbage such as fine cut leaves that were removed.

  Conventionally, some containers and tea bags have a fine mesh, but this is to improve ventilation, and the size of the tea leaves is not large enough to leave the mesh. In addition, when such a fine mesh is used, when picking tea leaves wet with rain or morning dew, or tea leaves with volcanic ash attached, water or volcanic ash is clogged in the mesh, and the wind does not escape from the side. Hit the tea leaves that had been plucked, and soared.

  An object of the present invention is to provide an apparatus for removing air that is well ventilated and that is not necessary for tea production (cut leaves or the like) at the tea plantation without taking it into the tea factory.

  The first means of the present invention is that a plucking device is provided below the portal frame, a tea leaf storage device is provided behind the plucking device, and a substantially vertical transport for transporting tea leaves plucked by the plucking device to the upper part of the tea leaf storage device. In a traveling type tea leaf picking machine that provides a duct and moves tea leaves upward by the rising wind, part or all of the tea leaf storage device is composed of a 3-8 mesh mesh, and fine cut leaves etc. that come out at the time of picking work Blow it out of the tea leaf container. The second means uses the tea leaf container of the first means as a container. The third means is to provide a plucking device below the portal frame, equip the rear of the plucking device with a tea leaf storage device, and provide a substantially vertical transport duct for carrying tea leaves plucked by the plucking device to the top of the tea leaf storage device In a traveling type tea leaf picking machine that transports tea leaves upward by the rising wind, a hood is provided at the top of the tea leaf storage device, and a part or all of the hood is composed of a 3-8 mesh mesh, and it comes out at the time of picking work Blow out fine cut leaves, etc., outside the hood.

  With the apparatus of the present invention, tea leaves and cut leaves can be selected while plucking tea leaves. By removing the cut leaves and the like at the time of plucking, a device for removing the cut leaves and the like in the tea factory becomes unnecessary. Further, when the cut leaves and the like are removed at the tea factory, the removed cut leaves and the like must be disposed. However, since the present invention drops the cut leaves and the like in the tea garden, the cut leaves and the like become fertilizers for the tea garden. Moreover, the quality of the tea product is improved by removing the cut leaves, and further, the oxidation of the tea leaves can be prevented by removing the cut leaves immediately after plucking.

  Further, even when tea leaves wet with rain or morning dew or tea leaves with volcanic ash attached are picked up, water and volcanic ash are not clogged in the mesh, and the picking operation can be performed smoothly. In the case of tea leaves wet with rain or morning dew, the present invention separates the water from the tea leaves and the surface of the tea leaves, so that the dew when the plucked tea leaves are received at the tea factory (measured the amount of attached water and received the whole The tea leaf price is calculated by subtracting it from the weight. In addition, if water is attached to the surface of the tea leaf after acceptance into the tea factory, the tea leaf will adhere to the belt conveyor or vibration conveyor of the transport device, but the water on the surface of the tea leaf should be separated at the time of plucking as in the present invention. Thus, adhesion to the transfer device can be prevented.

  An example in which the container of the tea leaf container is made in a mesh shape is shown in Example 1, and an example in which the hood on the tea leaf container is made in a mesh shape is shown in Example 2.

  The present embodiment is an example in which the container of the tea leaf storage device has a mesh shape. Two crawler type traveling devices 2 and 3 are connected by a gate frame 4 with the teacup 1 interposed therebetween, and a plucking device 5 is provided under the gate frame 4. Behind the plucking device 5 is provided a container (hereinafter referred to as a storage container) 6 which is a tea leaf storage device for storing tea leaves. The plucking device 5 and the storage container 6 are connected by transport ducts 7 and 8. The plucking device 5 is divided into two at the center, and the upper ends of the transport ducts 7 and 8 are connected to the storage container 6. Fans 9 and 10 are installed on the gate frame 4 and are connected to the plucking device 5 by flexible air ducts 11 and 12.

  The tea leaves harvested by the plucking device 5 while moving the teacup 1 by the traveling devices 2 and 3 are sent to the storage container 6 through the transport ducts 7 and 8. At the time of plucking, since the plucking device 5 plucks, the tea leaves A to be processed into products and the cut leaves B are mixed in the tea leaves. Cut leaves, etc. B have more heat of breathing than tea leaves A, and will be altered faster than uninjured tea leaves A, resulting in a state of burnt leaves and cannot be processed. Moreover, when cut leaves etc. are mixed, the quality of a product will fall. Therefore, it is necessary to remove the cut leaves B before processing, and in the apparatus of the present embodiment, when the tea leaves (tea leaves A + cut leaves B, etc.) are put into the storage container 6, the mesh of the storage container 6 is used. The tea leaves (tea leaves A + cut leaves, etc. B) are screened through the meshes, not through the tea leaves A, but through the cut leaves, etc. B. As the size of the mesh for passing cut leaves and the like B without passing through the tea leaves A, 3 to 8 mesh is preferable. Depending on the plucking method, 3-6 mesh may be sufficient. In the drawing, the substantially entire surface of the storage container 6 has a mesh shape, but a part of the storage container 6, for example, only the side plate, only the ceiling, only the bottom plate, or only a part of the side plate may be used. Only the portion where the cut leaves B or the like B are efficiently blown out of the storage container 6 may be formed in a mesh shape depending on the condition of blowing air to transfer the tea leaves. The cut leaves B passing through the mesh of the storage container 6 fall into the tea garden and become fertilizer for the tea garden.

  The tea leaves A stored in the storage container 6 are loaded onto the loading platform of the truck 19 at the headland of the tea garden. At this time, with the fulcrums 22 and 24 as axes, the holding container 6 is lifted upward by the holding arms 21 and 23, the lower door 16 is opened, and the tea leaves A are taken out. After the completion of extraction, the lower door 16 is closed, the storage container 6 is lowered, and plucking is possible.

  The present embodiment is an example in which the hood on the tea leaf storage device has a mesh shape, and the tea leaf storage device includes a storage frame 34 and a tea leaf storage bag 33. The configuration related to running and plucking is the same as that in the first embodiment. The upper ends of the transport ducts 7 and 8 are mesh-shaped hoods 31 and 32 whose bottom surfaces are opened, and are installed on the upper part of the housing frame 34. A plurality of tea leaf storage bags 33 are mounted on the storage frame 34 with their upper surfaces opened.

  When the tea leaves (tea leaves A + cut leaves B) transferred by the transport ducts 7 and 8 are put into the tea leaf storage bag 33, the tea leaves are not passed through the nets of the hoods 31 and 32 through the cut leaves B without passing through the tea leaves A. (Tea leaf A + cut leaf etc. B) is sorted by mesh. As the size of the mesh for passing cut leaves and the like B without passing through the tea leaves A, 3 to 8 mesh is preferable. Depending on the plucking method, 3-6 mesh may be sufficient. In the drawing, the substantially entire surface of the hood 33 is mesh-shaped, but a part of the hood 33, for example, only the side plate, only the ceiling, or only a part of the side plate may be used. Only the portion where the cut leaves B etc. are efficiently blown out of the hood 33 may be formed in a mesh shape depending on the condition of the air blowing to transfer the tea leaves. The cut leaves B that pass through the mesh of the food 33 fall into the tea garden and become fertilizer for the tea garden.

  When the tea leaves A are to be placed on the truck, the tea leaf containing bag 33 is removed from the containing frame 34 and the whole tea leaf containing bag 33 is put on the truck.

  In Example 1, the tea leaf storage device is a container, but a tea leaf storage bag may be attached to the storage frame as in Example 2, and a part or all of the tea leaf storage bag is made into a mesh shape of 3-8 mesh. Also good. Further, as in the second embodiment, the hood may be meshed and the tea leaf storage device may be a container as in the first embodiment. Further, in both Examples 1 and 2, when the tea leaf to be picked is a tea leaf wet with rain or morning dew, water is separated in addition to the cut leaf B, and in the case of the tea leaf to which volcanic ash is attached, Other volcanic ash can be separated.
