Abstract

[Challenge] Rice planting has become more efficient due to the mechanization of the process. However, this has led to an increase in missed or misplanted seedlings due to the machinery, as well as damage caused by giant apple snails. On the other hand, the process of planting seedlings by hand is time-consuming, and empty spaces are left unattended. [Solution] As a rice planting aid, it has a structure with two sharply pointed tips that are wide open, narrow in the middle, become parallel from there, and then close at the end, and also has a handle. The tips have the function of pinching and tearing off seedlings taken out of seedling trays for rice transplanters, the middle part has the function of holding the pinched seedlings to prevent them from falling, and the end has the function of planting bundled seedlings in the soil of the rice paddy.

Description

Technical Field

[0001] The present invention relates to a rice transplanting assisting tool.

Background Art

[0002] Today, rice transplanters are widespread in rice transplanting work. However, the machine may miss grabbing the seedlings, have planting deficiencies, or leave seedlings unplanted in the corners of the field. Furthermore, recently, damage by large snails has increased, and there are empty spaces in a fan shape for several meters centered around the water intake from the water channel. When inserting replacement seedlings into the empty spaces of the seedlings, labor is required to pick up the seedlings from the clump of seedlings and to bend the waist. When entering the field from the ridge, the correctly planted seedlings and their surroundings will be trampled and wither. In the areas damaged by large snails, it is necessary to repeatedly exterminate and insert replacement seedlings.

[0003] Originally, when there were empty spaces in the seedlings, one would pick up the seedlings from the rectangular clump of seedlings in the seedling box with fingers, bend the waist while moving the seedlings, and plant the seedlings in the soil of the field. This tool inserts the tip (d6) that replaces the fingers into the clump of seedlings taken out from the seedling box, gathers them (d1), fixes them (d2), and holds them perpendicular to the claws (d4). The section between (d3) and (d7) bends at an appropriate angle (r) and can plant the seedlings perpendicular to the ground of the field.

[0004] (d7)'s handle is stretchable and can insert replacement seedlings in a wide range up to about 2 meters in the distance directly below.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention provides a tool that can reduce the labor of picking up seedlings from the seedling box when inserting replacement seedlings, can fill in the unplanted areas far from the ridge without entering the field, can also reduce the labor of bending the waist, and can perform wide-range transplanting without damaging the already planted seedlings. [[ID=XXX]]

Means for Solving the Problems

[0006] The tip has an opening of approximately 13 mm and is made of iron, stainless steel, or synthetic resin to grasp the roots of seedlings removed from hard seedling trays. Seedlings caught in the tip narrow from approximately 13 mm to 4-5 mm, fixing the seedlings in place without them lying down, and inserting them into the soil of the paddy field. The angle between the tip and the handle is approximately 160 degrees, allowing for planting without hindering seedling growth. The handle is extendable, allowing for planting over a considerable area from approximately 80 cm to 2 m without bending over. [Effects of the Invention]

[0007] The rice planting aid according to the present invention allows for easy grasping of seedlings and planting them over a wide area without having to enter the rice paddy. [Brief explanation of the drawing]

BEST MODE FOR CARRYING OUT THE INVENTION

[0015] (Configuration) The rice transplanting assisting tool includes a claw with a widened tip opening (opening width d6 = approximately 13 mm) (length of the widened claw d1 = approximately 13 mm) and parallel claws (length of the parallel claws d2 = approximately 13 mm) (height of the parallel claws d5 = approximately 14 mm) as shown in FIGS. 2 and 3. The confluence point at the back of both claws ends with a surface (width of the surface d4 = approximately 4 mm). From both claw parts, an angle (r = approximately 160 degrees) (d3 = approximately 150 - 160 mm) is formed in the middle and connected to a support rod, and the support rod (d7 = approximately 850 - 2000 mm) is stretchable.

[0016] (Operation) As shown in FIG. 1, the rice transplanting assisting tool has two claws at the tip opening. The width between the claws is wide, and several bunches of seedlings taken out from the seedling box are cut. The space between the claws gradually narrows to collect the cut seedlings and hits the innermost surface to stabilize them. Both claws insert the seedlings collected between them into the empty spaces in the field together with the claws and complete the transplanting by pulling them out at an appropriate depth.

[0017] (Effect) The effects of this embodiment will be enumerated and described. (1) In this embodiment, the bunches of seedlings taken out from the seedling box can be bundled so that they can be transplanted without directly touching them by hand. (2) Also, the seedlings are collected between both claws and are in a stable state for planting. (3) Due to the shape of both claws, the seedlings can be smoothly inserted into the soil. (4) Due to the stretchability of the support rod, the seedlings can be transplanted over a wide range without entering the field.

Claims

1. The tool has two sharply pointed ends (d1) that are wide open, narrow in the middle, become parallel (d2), and then have a closed end (A) and a handle (B). The ends (d1, d6) have the function of pinching and tearing seedlings taken out of seedling trays for rice transplanters, the middle section (d1) and (d2) has the function of holding the pinched seedlings to prevent them from falling, and the end point has the function of holding bundled seedlings in the soil of the rice paddy.

2. The distinctive feature is the structure that supports the seedlings with a surface at the final point (d4) of the two sharply pointed tips, preventing them from lying down.

3. (d7) The length of the main body is adjustable.
