Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a teacup-stretching type tea-cutting device, and particularly to a pruning trunk feeding structure when a rotary-type pruning machine is mounted as a tea-cutting machine unit.
[0002]
BACKGROUND OF THE INVENTION
  When performing a tea cutting operation such as a plucking operation or a pruning operation in a relatively large tea plantation, a tea cutting device that can accommodate a large amount of harvested tea at once is often applied. As such a tea-cutting device, a riding-type device in which an operator directly works on the tea-cutting device is widely used. In general, an appropriate tea cutter unit that substantially performs a tea cutting operation is attached to a traveling machine unit that travels across a teacup. Further, a container-type accommodation unit is often provided behind the tea cutter unit so that a large amount of the picked tea leaves can be accommodated and the picked tea leaves can be discharged to the truck bed more easily.
[0003]
  By the way, in performing the pruning work for pruning the branch of tea tree among the tea cutting work, usually, the pruned branch trunk is left dropped in the intercostal space or the like to be part of the fertilization effect, It is common to use for topsoil as management. In order to perform such a pruning operation using the above-described riding-type tea-cutting device, first of all, a pruning unit is attached as a tea-cutting machine unit, and a pruning branch trunk is placed in a container-type accommodation unit. It has a duct for dropping into space. That is, the branch trunk pruned by the pruning machine unit is once lifted and transferred by the relay transfer device, and then reaches the intercostal space through the duct and is discarded.
[0004]
  In this way, the riding type tea-cutting device provided with a container-type accommodation unit can be appropriately evaluated in terms of being able to perform both plucking work and pruning work by appropriately replacing the constituent members. There was also room for improvement as shown in.
  That is, conventionally, there are two types of cutting blades for plucking and pruning a tea cutting operation: a so-called clipper type shown in FIG. 7 and a so-called rotary type shown in FIG. Mainly any one of these types of cutting blades is applied. In particular, when the rotary type cutting blade is used, the cuttings of the tea tree are finished beautifully, so the plucking operation is performed with the clipper blade type cutting blade, and the subsequent pruning operation is performed with the rotary type cutting blade. Requests to start are being made by tea farmers.
[0005]
  By the way, the pruning machine unit 3B to which the clipper blade type cutting blade is applied is provided with a draft tube 38 in front of the cutting blade, and the pruning branch stem A is moved behind the cutting blade 30 by blowing air from the front of the cutting blade 30. To send to. On the other hand, in the pruning machine unit 3A ′ to which the rotary type cutting blade is applied, since the rotary blade 30A ′ is in the way, the pruning branch stem A cannot be sent to the rear of the rotary blade 30A ′ by blowing air from the front of the cutting blade. .
  For this reason, as shown in FIG. 8, the air from the fan is sent from the vicinity of the central portion of the branching machine unit 3A ′ toward both ends in the guide cylinder 33 ′, so that the pruning branch stem A is sent to the branching machine unit. A structure is adopted in which it is dropped into the intercostal space S from both sides of 3A ′. However, such a transfer form of the pruned branch trunk A is not a preferable form because the pruned branch trunk A accumulates on the traveling device 21 'or the like. Of course, when the above-described riding-type tea cutting device is mounted with the clipper-type pruning machine unit 3B, the pruning trunk A is once moved up by the relay transfer device 5 and then into the intercostal space S through the duct. It has a structure that can be fed in, and can prevent the pruned branch trunk A from accumulating on the traveling device 21 or the like. Thus, the method of dropping the pruning trunk A from both sides of the pruning machine unit 3A into the intercostal space S cannot be said to be a rational one that fully utilizes the functions of the entire apparatus.
[0006]
[Technical issues for which development was attempted]
  The present invention has been made in recognition of such a background, and has not been conventionally performed in a teacup-stretching type tea-cutting apparatus provided with a pruning machine unit to which a rotary-type cutting blade is applied. It is possible to send the pruning trunk to the rear of the cutting blade, and once it is lifted and transferred by the relay transfer device located behind the pruning machine unit, it can be sent to the intercostal space through the duct.TeaThis is an attempt to develop a straw-climbing type tea-cutting device.
