Description

  The present invention relates to a traveling tea leaf plucking machine that plucks tea leaves while traveling along a teacup.

There are two types of traveling type tea leaf plucking machines: a type in which the plucked tea leaves are transferred rearward and accommodated in a tea bag, and a type in which the plucked tea leaves are once transferred upward and then dropped into a tea leaf storage device . In the latter case, the tea leaf storage device includes a tea bag type (for example, see Patent Document 1) and a container type (for example, see Patent Document 2). In the traveling tea leaf picking machine equipped with a container, the inner surface of the container is made of iron plate or aluminum plate, and recently, the iron plate or aluminum plate is made of mesh to improve air permeability. There was something to do.

  The tea leaves picked by the picking device and discharged from the transport duct delivery end hit the iron plate or aluminum plate at a wind speed of about 10 m / second and are stored in the tea leaf storage device. At this time, the impact hit the iron plate or aluminum plate. And tea leaves were sometimes damaged.

  Usually, the tea leaves are picked out so as not to damage them and then transported to the tea factory. Should a tea leaf be damaged, fermentation starts from the scratched portion, and the quality of the tea leaf material is reduced. This quality affects the tea leaf price. An object of the present invention is to provide a traveling tea leaf picking machine that picks and transports tea leaves without damaging them.

  The traveling tea leaf plucking machine of the first means of the present invention is an abbreviation for carrying a plucking device below the gate mold frame, a tea leaf collecting device behind the plucking device, and a tea leaf plucked by the plucking device to the top of the tea leaf storage device. In addition to a vertical transport duct, an impact absorbing member is provided in a portion where the tea leaves discharged from the transport duct sending end portion come into contact. In the traveling type tea leaf plucking machine of the second means, the impact absorbing member of the first means uses a material that softens the impact, such as rubber, cloth or chemical fiber.

  According to the first aspect, the picked tea leaves are not damaged, and high quality tea leaves can be picked and conveyed. According to claim 2, it is possible to use a familiar and inexpensive member.

  Examples 1 and 2 show an example in which the tea leaf storage device is made into a container type and the container has a mesh shape, and Example 3 shows an example in which the tea leaf storage device is made into a tea bag type and the hood on the tea bag has a mesh shape.

  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. Reference numeral 13 denotes an impact absorbing member affixed to the wall above the rear surface of the storage container 6, and is provided at a position where the tea leaves discharged from the delivery end portions of the transport ducts 7 and 8 hit.

  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 this time, the tea leaves jump out into the storage container 6 vigorously on the wind of the fans 9 and 10. Most of the tea leaves hit the wall of the storage container 6, and in the case of the present embodiment, hit the mesh-like wall. Originally, the mesh-like storage container 6 is for discarding damaged tea leaves such as broken leaves from the mesh and storing normal tea leaves that are not damaged. It will be hurt. The damaged tea leaves have more heat of breathing than the tea leaves A, and the tea leaves A are deteriorated faster than the uninjured tea leaves A, causing a state of burning of the leaves and cannot be processed. In addition, if tea leaves that are damaged are mixed, the quality of the product deteriorates. Therefore, the tea leaves that come out vigorously are applied to the impact absorbing member 13 so as not to damage the tea leaves. The tea leaves that hit the impact absorbing member 13 are stored in the lower portion of the storage container 6 without being damaged and without losing momentum. As the material of the impact absorbing member 13, a material such as rubber, cloth, chemical fiber, etc., that softens the impact without damaging the tea leaf even if it hits the tea leaf is used.

  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 performed.

  The present embodiment is an example in which the position of the impact absorbing member of the first embodiment is changed. In this embodiment, the impact absorbing member 14 is hung from the ceiling of the storage container 6 instead of being attached to the wall of the storage container 6. Before the tea leaf hits the wall of the storage container 6, it strikes against the impact absorbing member 14, and the impact absorbing member 14 becomes warm, and the tea leaf is lost and the tea leaf is stored in the storage container 6.

  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 open, and are installed on the upper part of the housing frame 34. The impact absorbing member 15 is affixed to a position where the tea leaves discharged from the delivery end portions of the transport ducts 7 and 8 above the rear surfaces of the hoods 31 and 32 hit. A plurality of tea leaf storage bags 33 are mounted on the storage frame 34 with their upper surfaces opened.

  When the transported tea leaves are put into the tea leaf storage bag 33 by the transport ducts 7 and 8, they are applied to the impact absorbing members 15 of the hoods 31 and 32, and then dropped into the tea leaf storage bag 33.

  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.

  The tea leaf storage devices of Examples 1 to 3 have a mesh shape, but the same is true for non-mesh type devices.

FIG. 3 is a partial cross-sectional view of a side surface according to the first embodiment. FIG. 4 is a partial cross-sectional side view of Example 2. FIG. FIG. 9 is a partial cross-sectional side view of Example 3.
