The riding type tea leaf plucking machine 1 having such a configuration is used as follows. First, when the engine 2 is started, the hydraulic pump operates, and the hydraulic devices such as the hydraulic cylinders and the hydraulic motors 18 and 23 become operable. Then, when the traveling operation levers 6 and 6 are operated, the rubber crawlers 4 and 4 are driven by the hydraulic motor and the machine body travels. In the tea orchard, the rubber crawlers 4 and 4 run across the ridges on both sides of the tea ridge, and the plucking unit 12 plucks the tea leaves on the entire surface of the ridge in one machine run.

When the blower operation lever 7 is operated, the blower 11 is driven by the belt transmitted from the engine 2, and the pressure wind generated by the blower 11 is blown by the blower ducts 13 on the left and right sides of the plucking section 12 via the flexible pipe 11a. , 13 sent to. When the tea leaf storage frame operating lever 8 is operated, the tea leaf storage frame 15 is driven by the belt transmission system from the engine 2 to rotate horizontally about the rotary shaft 14, and a plurality of tea leaf storage frames 15 are arranged radially from the center of rotation. Tea leaves are stored in the tea leaf storage bag. When the tea leaves are fully filled in each tea leaf storage bag, the plucking operation is temporarily suspended, the tea leaf storage bag is replaced, and the plucking operation is restarted.

When the plucking part elevating lever 9 is operated, the plucking part 12 is moved up and down by the hydraulic cylinder to adjust the plucking height. When the plucking section operating lever 10 is operated, the hydraulic motors 18 and 23 are operated, the cutting blade 16 of the plucking section 12 is reciprocally driven by the crankcase 19 to pluck the tea leaves, and the tea leaves plucked by the cutting blade 16 are rotated. It is scraped backward by the scraping brush 17. The tea leaves that have been scraped by the scraping brush 17 are sent to the feed blades 36, 36 of the endless conveyors 20, 20 that are rotating outwardly, respectively, and fall into the pressure feeding frame 21 of the air blowing duct 13, so that the pressure air is blown. Is sent to the tea leaf storage frame 15 via the tea leaf transport duct 22 and stored in a storage bag.

According to the present invention, during such a tea leaf harvesting operation, since the transport end portions of the endless conveyors 20 and 20 are extended to the position where they pass through the pressure feeding frames 21 and 21 of the air ducts 13 and 13, they are plucked. The tea leaves plucked by the section 12 are conveyed to the pressure feeding frames 21 and 21 without being left, and dropped, and are sent from the pressure feeding frames 21 and 21 to the tea leaf accommodating frame 15 by the pressure air through the tea leaf conveying ducts 22 and 22. Store in a storage bag. Even if the tea leaves are entangled in the chain 35 of the endless conveyor 20, the compressed air from the pressure feeding frame 21 acts on the conveyor 20 at the transport end position of the conveyor 20, and the tea leaves are easily separated from the chain 35. The tea leaves that have come off the chain 35 are pressure-fed from the pressure-feeding frame 21 and do not clog. Therefore, it becomes possible to improve the work efficiency by increasing the plucking speed of the tea leaf plucking machine 1.

In the above embodiment, the present invention is applied to the whole surface plucking device that plucks the tea leaves on the entire surface of the tea tree ridge by one run, but this is applied to the one-sided shredded tea leaves of the tea tree ridge by the reciprocal running. It can be similarly applied to a single-sided plucking device for plucking.

[Effect of device]

 As described above, according to the tea leaf accommodating device of the riding type tea leaf plucking machine of the present invention, the conveying end portion of the endless conveyor that feeds the tea leaves plucked by the plucking device to the pressure feeding portion of the air blowing duct is Since it is extended to the position where it passes through the pressure feeding unit, the tea leaves plucked by the plucking device can be conveyed to the pressure feeding unit of the air duct without leaving. Then, the tea leaves can be sent out from the pressure-feeding unit through the air duct, transported to the storage container, and stored therein. Further, even if the tea leaves are entangled in the chain of the endless conveyor, the pressure air from the pressure feeding section acts on the conveyor end position of the conveyor, so that the tea leaves are easily detached from the chain and pressure-fed, so that the tea leaves are not clogged. Therefore, the plucking speed of the tea plucking machine can be increased to improve work efficiency.
