Description

[Detailed description of the invention] "Industrial field of application" This invention relates to a tea-picking work aid (helper) using a tea-picking machine.

``Prior art'' Conventionally, two people support the machine frame of a rotary blade tea plucking machine along the arc-shaped crown of a tea tree on both sides of the tree crown to perform tea plucking work, or the machine frame of a rotary blade tea plucking machine supports the machine frame on both sides of the tree crown. One side was supported on the ground by a ground drive wheel, and the other side was held by one person to perform tea picking work (Utility Model Publication No. 164266/1983). However, in any case, the level of tea plucking performed by a rotary blade tea plucking machine is greatly affected by the feel of the hand gripping the machine frame and the unevenness of the ground, resulting in fluctuations in the level of plucking of new leaves after crown pruning. It has been difficult to improve the plucking yield because the quality of the plucked tea leaves is uneven and the new leaves cannot be plucked evenly close to the pruning surface.

``Problems to be solved by the invention'' This invention pruns the crown of a tree into an arc shape, picks new buds evenly close to the pruning surface, improves the plucking yield, and performs the plucking work without relying on human power. The purpose is to obtain tea picking helpers who are able to do so.

``Means for solving the problem'' This proposal involves laying one rail between parallel tree crowns each close to the base of one side of the tree crown, connecting the tops of both legs with a continuous rod, and One rail running wheel is provided at the lower end, and two rail running wheels are arranged in the running direction at the lower end of the other side leg to form a gate-shaped support frame that can run on the rail, and the lower part of the both legs is Each of the running wheels is bent to one side and supports the running wheels on the rail, and a picker frame support that is adjustable in elevation is provided on both sides and the center of the connecting rod via a spindle, and the support in the center is provided. The tea picking helper is slidable along the continuous rod, and the central support is supported on one side and the other side so as to be rotatable around the spindle.

"Operation" Therefore, one rail is laid on the ground in the middle of the parallel tree crowns, each close to the base on one side of the tree crowns. Then, the gate-shaped support frame is placed across the tree crown, one wheel of one leg is supported on one rail, two wheels of the other leg are supported on the other rail, and the same support frame is supported. can be run along a track and across the tree canopy. At this time, since the lower parts of both legs are bent to one side, both legs can run in the center of the middle ground of the tree crown (see Figure 2). In this state, both ends of the machine frame of the plucking machine are supported by the central and one side supports, and the plucking machine is supported along one side of the tree crown (this state is shown by the solid line in Figure 2). Then, by starting the plucking machine and moving the portal support frame along the rail, one side of the upper surface of the tree crown can be pruned or new shoots plucked. Next, one side of the machine frame is separated from the one side support, and the center support 8 of the machine frame is rotated to the other side around the central spindle 11, and the center support is moved from the solid line position in Figure 2. One side of the machine frame is supported by the other side support by sliding it along the connecting rod to the imaginary line position. This state is shown by imaginary lines in FIG. By running the portal support frame in the opposite direction to the above-mentioned running direction, the other side of the upper surface of the tree crown can be pruned or new shoots removed.

``Example'' A portal support frame 6 is formed by connecting the upper parts of both legs 1 and 2 with a connecting rod 3. As shown in FIG. 1, one side leg 1 is formed by one leg rod 1', has a lower part bent 7 to one side, and has one rail running wheel 4 provided at the lower end. The other side leg 2 is formed by two leg rods 2', 2', the lower part of which is also bent 7 to one side (and not the other), and has two track running wheels 5, 5 at the lower end.
is arranged in the direction of travel. A support 8 for the machine frame 10 of the plucking machine 9 is provided at the lower end of a spindle 11 that can be freely adjusted up and down on both sides and the center of the connecting rod 3, and the spindle 11 in the center is provided with a traveler that can freely slide along the connecting rod 3. 12 and at its lower end is supported so as to be rotatable from one side to the other or in the opposite direction about the spindle 11 at the center. The connecting rod 3 is adjustable in expansion and contraction and is fixed with a thumbscrew 13. L on rails 14, 14
Shaped steel is preferably used, and groove wheels are preferably used for the wheels 4 and 5, and the rails 14 and 14 are preferably fixed to the upper surface of a corrosion-free synthetic resin pile 15 with screws. Both legs 1,
2 is foldable toward the center of the connecting rod 3 as shown in FIG. 9, and the folding device is shown in FIGS. 4 to 8. One side leg 1 is a bearing tube 16 provided at one end of the connecting rod 3.
By pivoting the upper end bent part and crimping the pin 18 provided at the bent part to the tube 16 with the force of the spring 17, the leg rod 1' can be opened and closed in the left and right directions in Figure 2 following the rail 14. support. The machine frame support 8 is formed by upward clips 19, 19' and can be opened and closed by a spring 20 and a handle 21. 22 in the figure is a set screw for the lift adjustment spindle 11, 23 is a fitting recess for the pin 18, 24 in FIGS. 7 and 8 is a pivot pin for the leg rod 2', 25 is a tightening screw, 26 is a plate to be tightened.

"Effects" Since this project is configured as described above, the crown pruning surface a by the plucking machine 9 is formed at a constant level from the rails 14, 14, and the new shoots b extending upward from the pruning surface a.
can be plucked at a constant level along the rails 14, 14 by the plucking machine 9, so that the plucking level of the new shoots b is at the pruning plane a.
Therefore, the uniformity of the new shoots (b), that is, the tea quality, can be improved, and the harvesting yield can be improved by making it possible to perform planned harvesting using a gauge. In addition, since the plucking machine 9 is supported by the portal support frame 6 at the same level as the rail 14 by the three wheels 4, 5, and 5 without play, it is only necessary to move the support frame 6, which requires no effort. It is possible to improve safety by reducing vibration and fatigue.
can be laid at the corner of the ground c in the middle of the tree crown without interfering with deep cultivation, weeding or fertilization of the ground c.
