JPS5848130B2 - Tea branch and leaf mower with adjustable cutting blade arc surface - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tea branch and leaf cutter, in which the arc surface of the cutting blade itself is adjustable, so that the arc surface of the cutting blade can be adjusted according to the arc surface of the tea ridge to be cut, or according to a desired arc. The purpose is to prevent uncut leaves and uneven branch arrangement, thereby contributing to good tea plantation management.

The surface of tea ridges generally has a gentle arc shape, and the cutting blade surface of the tea branch and leaf trimmer used to trim these branches is also inevitably formed in an arc shape, but tea ridges are the same. Even in a tea garden, the arc of the tree's surface varies depending on the ridge, and even more so if the tea garden is different, and it also varies considerably depending on the degree of growth.

However, in conventional branch and leaf trimmers, the arc shape of the cutting blade is made to be average, and the length of the cutting blade is fixed. When reaping, it is not possible to reap uniformly along the previous ridge shape, causing unnecessary reaping or uneven reaping.Also, when reshaping the existing tea ridge to form the desired arc, it is difficult to reap uniformly. They were forced to perform inefficient work such as mowing one row several times.

In view of this point, the present invention is characterized in that the arc shape of the cutting blade of a single branch and leaf trimmer can be freely set to a desired arc surface. I'll explain.

Reference numeral 1 is a relatively strong frame with a substantially river-like front face, on which a reinforcing culm 2 is constructed, and the lower end 1a of one side is fixed to one end of the arc-shaped base plate 3, and the lower end 1b of the other side is fixed to the arc-shaped adjustment device 18 of the arc-shaped base plate 3. Join.

That is, the arcuate adjustment device 18 has a configuration in which the insertion tube 4 is inserted into the bolt 6 protruding from the arcuate base plate 3, and nuts 7 and 8 are threaded on the front and rear thereof. Fixedly installed in pipe 4.

Reference numeral 5 denotes a prime mover attached to one end of the arc-shaped base plate 3 together with a crank mechanism 12.

Reference numerals 9 and 10 have a clipper-shaped cutting blade 9'IO' on the front side, and are held slidably on the arc-shaped base plate 3 by pivot retainers 11, 11..., and one end is attached to the crankshaft. They are an upper blade plate and a lower blade plate connected to the mechanism 12.

13.14 is a guide plate fixed to the rear bottom surface of the arcuate board 3;
15, 15 is a handle, and 16 is a guide sheet for brushing off the cut branches and leaves between the tea furrows.

Note that the natural arc surface of the arc-shaped base plate 3 is formed to be slightly flatter than the arc of a general brown ridge, and each sliding surface of each blade plate is coated with an oil-less resin such as Rulon resin. , it is possible to eliminate the increase in sliding resistance caused by changing the arc.

Therefore, in order to perform reaping work using the branch and leaf trimmer of the present invention formed in this manner, first, as shown in Fig. 3, the bottom surface of the cutting blade is lightly touched along the arc surface of the ridge 17 (in the direction across the brown ridge). If there is a gap at both ends (solid line in the figure), move the nut 8 of the arc adjustment device 18 toward the free end of the bolt appropriately, and then remove the nut 7. If they are moved and fixed in the same direction, the arc-shaped base plate 3 will enlarge its arc, and the blade plates 9 and 10, the guide plate 13, and the stabilizer plate 1 will move accordingly.
4 also increases the arc, so it matches the arc of the ridge 17.

(Indicated by the chain line in the same figure) If, on the other hand, a gap is created between the arc of the ridge and the arc of the cutting blade at the center, the adjustment operation described above must be reversed, that is, the nuts 7 and 8 should be moved between the bolts. If the base plate 3 is moved appropriately toward the fixed end, the end of the base plate 3 on the adjusting device 18 side is pulled by the bolt 6 and its arc is reduced, so that the arc shapes can also be adapted to each other.

It should be noted that the structure of the present invention can of course be applied not only to a tea branch pruning machine but also to a tea confectionery plucking machine.

As described above, the present invention allows the cutting blade arc surface of the tea leaf trimmer to be freely set by changing the arc of the board, so even if the arc of the tea ridge is different, the arc It is possible to set the shape of the cutting blade to suit the shape of the blade, and it is possible to obtain tea ridges with a desired arc surface.Also, it can be adapted to the existing tea ridges, so there is no need for unnecessary cutting or cutting as in the past. Therefore, it is possible to create a good tea garden with extremely light work without causing uneven branch trimming and without having to trim a single tea garden several times.

Claims (1)

[Scope of Claims] 1. An arcuate adjusting device in which the lower end of one side of a relatively strong frame is fixed to one end of an arcuate base plate that pivotally holds the blade plate, and the other end of the frame is provided at the other end of the arcuate base plate. A tea branch and leaf mower with an adjustable arc surface of the cutting blade combined with the blade. 2. At one end of the arc-shaped substrate that pivotally held the blade plate, the lower end of one side of a relatively strong frame is fixed, and the lower end of the other side of the frame is inserted with a bolt protruding from the other end of the arc-shaped substrate. A tea branch and leaf cutter in which the arc surface of the cutting blade, which is fixed to an insertion tube whose front and rear parts are adjustable with nuts, is adjustable.
