Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a rice seedling shearing machine used to shear the leaves of seedlings as part of the rice cultivation process.

[Prior Art] Leaf pruning is a means of suppressing the growth of leaf parts and promoting root development, and conventionally, a four-wheeled leaf pruner that moves along a seedling nursery box has been used.

[Problem that the invention aims to solve] Conventional leaf pruners are arranged in a row along the seedling box,
Move one row at a time. For this reason, it was necessary to leave gaps between the rows for people to pass through.
In addition, conventional leaf shearers have four wheels, making their structure complicated.

This idea simplifies the structure by allowing a gap to be provided between every two rows.

[Means for solving problems] The explanation will be based on the drawings.

A reciprocating cutter 4 is attached to the front end of a hand-held rod 3 that has a shoulder strap 1 and a hand-held handle 2, and a power source 5 carried on the body and the reciprocating cutter 4 are connected by a rotary power transmission means 6 passing through the hand-held rod 3. A paddy rice seedling pruning machine 8 is constructed by connecting the hand-held rod 3 with a downwardly extending wheel support rod 7 attached to the tip end thereof.

[Example] The explanation will be based on the drawings.

3 is a hand-held rod; 1 is a shoulder band attached to the hand-held stick 3; and 2 is a hand-held handle attached to the hand-held stick 3. 4 is a reciprocating cutter attached to the front end of the handheld rod 3 via a casing 9, and 5 is a power source (for example, an engine) that is carried on the body by being carried on the back or hanging from the waist. 6 is a rotary power transmission means (drive shaft, cable, etc.) that passes through the handheld rod 3
, the reciprocating cutter 4 and the power source 5 are connected. 7 is a wheel support rod extending downward provided at the tip of the handheld rod 3, and the wheel 1 is attached to the lower end of the wheel support rod 7.
1 is attached to the casing 9 which supports the reciprocating cutter 4 so as to be vertically supported, and by tightening the bolt 10, the casing 9
It is becoming fixed.

In addition, when the rotational power transmission means 6 is a cable, the power source 5 can be separated and carried on the back without being fixed to the rear end of the handheld rod 3.

The reciprocating cutter 3 has two comb-like blades 4a,
4b overlap and one side reciprocates laterally to cut, and this exists as a well-known ready-made product.
The reciprocating motion is driven by an eccentric pin, and in the present invention, an eccentric pin 12 is provided at the tip of the transmission structure. 13 is a seedling raising box, and 14 is a seedling.

The structure can be simplified most if the wheel 11 is a single wheel, but as shown in Fig. 3, a tandem type wheel 11,
It may be set to 11.

Further, as shown in FIG. 4, a flange 11a may be provided on the inner surface of the wheel 11 to catch the edge 13a of the seedling box 13.

[Operation] While driving the power source 5 with the handheld stick 3 in hand,
When supported by the wheels 11 and moved forward, the reciprocating cutter 4 can cut rice leaves.

[Effects of the invention] According to the invention, since the power generation source is attached to the user, it is possible to move freely even on narrow roads, and since the reciprocating cutter is used, the cutting of leaves is reliable, and since the handheld stick 3 has wheels 11 at the front end, This supports the cutter at a constant height by resting on the ground, and has the effect of evenly and highly efficiently pruning the leaves of the two rows of seedling boxes.
