Abstract

[PROBLEMS] To provide a farm tool for reliably landing a germinated seedling integrated with a multi-cloth on a paddy ground, which is an important point in paddy rice multi-sowing cultivation.
SOLUTION: In order to ensure that the germinated seedling integrated with the multi-cloth is landed on the paddy field ground, it has a moderate weight and a unique uneven surface structure that does not damage the germinated seedling. Using a winter tire 1 equipped with a steel wheel of a light cargo automobile and rolling the tire 1 against the germinated seedling, the multi-cloth and the germinated seedling are pressed against the paddy ground. Furthermore, since the gas is pushed out between the tire 1 and the tire 1 (between the striations) because the structure is separated from the tire 1 with respect to the swelling caused by the generated gas, the multi-cloth is cut open. The seedlings can be stepped on while maintaining the herbicidal effect of the multi-cloth.

Description

  The present invention relates to a seedling treading machine for pressure-bonding paddy rice seedlings and multi-cloths to paddy ground in paddy rice cloth direct sowing cultivation.

  Paddy rice cloth mulch direct sowing cultivation sandwiches paddy rice seeds between double non-woven cotton (hereinafter referred to as mulch cloth), spreads the mulch cloth in paddy fields, draws water from under the mulch cloth for a certain period of time Wait for germination of paddy rice seeds sandwiched between cotton by floating the multi-cloth in the paddy field. Germinated seedlings can grow until the third leaf comes out due to seed germ nutrition, but after that they must absorb nutrients from the soil. Therefore, when the germinated seedlings grow to the third leaf, the water in the paddy field is drained and the floating multi-cloth is landed on the paddy field. While the multi-cloth is floating, weeds start to emerge from the paddy ground, but cannot grow much due to the shading by the multi-cloth.

Also, if the paddy field is drained, the weeds will not be able to grow because they become a heavy weight for the weeds that have started to generate multi-cloth. About 50 days after laying, this multi-fabric is decomposed or corroded by the action of microorganisms in the soil, but at the same time, the weeds that grow are also corroded. The greatest feature of this farming method is that weeds in paddy fields can be removed without using pesticides such as herbicides by the physical action of this multi-cloth. Another feature is that it does not require time to create seedlings and rice planting machines, as in the conventional cultivation of rice, and as mentioned above, there is almost no weed, so the labor required for weeding can be saved.

When it is confirmed that the seedling roots have sufficiently entered the soil, water is drawn from the top of the mulch cloth and water is managed for general rice cultivation.
The above is the outline of paddy rice mulch direct sowing cultivation. One important point of this farming method is when the mulch cloth is landed on the paddy field. The seedlings begin to grow by absorbing nutrients from the soil. However, in this state, to put it in an extreme way, the seedlings that floated in the air only fell to the ground, so the roots might become floating from the soil, and eventually the rice grows and grows. There is a risk that the rice will fall if the upper part of the paddle becomes heavy. Therefore, it is necessary to crimp the seedling roots to the paddy ground as much as possible.

  In addition, when landing is confirmed and water is drawn from the top of the multi-cloth to maintain a certain level of water depth, the multi-cloth itself floats in the water again and the seedlings are lifted along with it, and the roots float up and grow. In this case, since the yield of rice is affected, it is necessary to press the entire multi-cloth against the paddy field.

The people who have experienced this farming method have stepped on the seedlings directly with their feet when they landed the multi-cloth, or stepped on a round plate-shaped swordfish on their feet. However, walking in the paddy field in this way is a very time-consuming and inefficient task. Also, in response to the bulge caused by bubbles in the multi-cloth, the bulge is incised with a knife or the like and the gas inside is exhausted. However, when this is done, light enters through the incision point of the multi-cloth later, and weeds from that part May occur.
As a method for fixing seedlings in a nursery, a method using a roller is described in Japanese Patent Application Laid-Open No. 2008-29227, which is different from the problem of the present invention.
JP 2008-29227 A

  The problem to be solved is to provide agricultural tools to promote the reliable landing of multi-cloth on paddy ground, which is an important point in paddy rice multi-direct sowing cultivation, and realize efficiency and labor saving of seedling treading work There is a thing. In addition, organic matter in the paddy soil is fermented and gas is generated during the period when the multi-cloth is floating in the water, and gas accumulates on the lower surface of the multi-cloth, creating a situation where the multi-cloth is inflated. Even if this bulge is drained from the paddy field and the multi-cloth is dropped on the paddy ground, the multi-cloth does not disappear until it is dried to some extent.

  The present invention is a light cargo vehicle with an appropriate weight that will not damage the germinated seedlings in order to ensure that the germinated seedlings, which are an important point in paddy rice cloth direct sowing cultivation, are landed on the paddy ground. Using a rubber tire equipped with a steel wheel, the multi-cloth and the germinated seedling are pressed against the paddy ground by rolling the tire against the germinated seedling.

  The seedling machine of the present invention can sufficiently press the multi-cloth after the landing of paddy rice cloth multi-direct sowing cultivation onto the paddy ground by the moderate weight of the steel wheel and the contact pressure due to the unevenness of the winter tire. In addition, the structure of the axle makes the seedling machine rotate with less force, thus saving labor and reducing work time.

  Even when the mulch of fabric is swelled by the gas generated from the paddy field, the gas generated when the seedling machine is stepped on the seedling machine due to the structure of the seedling machine is separated from the tire. Create a situation where it is pushed between the seedlings and the seedlings (between the two items). As a result, seedling can be spread without incising the multi-cloth. As the mulch cloth dries more, the bulge due to the gas becomes smaller. At that point, when the streak is finished and the seedling machine is used as a finish, the entire mulch cloth can be pressed against the paddy ground. .

The configuration of the present invention will be described with reference to the drawings based on the embodiments.

  In carrying out the present invention, if the seedling is not stepped on by a rolling machine having a certain weight within a range that does not damage the germinated seedling, the seedling cannot be expected to be pressed against the paddy field. Therefore, we decided to use winter tires equipped with steel wheels for light freight cars, which are considered to be the best ones around us. The reason for using a winter tire is that the unevenness of the tire surface is larger than that of a summer tire, and an improvement in contact pressure per unit area can be expected.

  As shown in FIG. 4, an axle mounting sheath pipe 7 is welded to the center portion of the steel wheel 6 to the steel wheel 6 attached to the winter tire 1. Further, in order to fix the axle-attaching sheath tube 7, the sheath-tube supporting rebar 8 is welded to the steel wheel 6 and the axle-attaching sheath tube 7. Next, the handle attachment bolts 5 for attaching the handle 2 of the seedling machine are welded to both ends of the axle pipe 3 that matches the inner diameter of the axle tube 7 for attaching the axle. Next, the spacer sheath pipe 4 is manufactured so that the tire centerline interval of the tire to which the axle attaching sheath pipe 7 is attached is 25 cm suitable for the seedling treading operation. When each part is completed, lubricating oil is applied to the inside of the axle pipe 3 and the shaft pipe for attaching the axle for smooth rotation and reduction of friction. Each member completed in this way is assembled into a shape suitable for the work.

  For seedling treading work, two tires are mounted on the axle pipe 3, a spacer sheath pipe 4 is manufactured so that the center line spacing of the tire is 25 cm, and the seedling machine handle 2 is bolted to the axle pipe. And complete. Now we can achieve results for the issues of this plan.

  When the multi-cloth 9 is dried to some extent and the bubbles on the multi-cloth 9 are reduced, if three tires are mounted and the whole multi-cloth is rolled, the multi-cloth is more pressed against the paddy ground.

  One tire treader tire can be used, and it can be used for crimping multi-cloths other than as a seed treader. The mulch cloth used for paddy rice mulch direct sowing cultivation is produced at the factory and is rolled out with a width of 1.1 meters and a length of 100 meters. This is spread in paddy fields. At this time, 10 centimeters of a width of 1.1 meters are piled up. The multi-cloth will turn over against the wind, so the primary temporary presser will be applied, and water will immediately penetrate the cloth. It is necessary to counter the wind by increasing the weight of the cloth itself. At this time, it is necessary to infiltrate water into the 10-cm portion that has been quickly superimposed. For this purpose, water is drawn under the multi-cloth spread on the paddy field, and the overlapping parts of the multi-cloth are rolled with a seedling machine with a single tire, so that the water present under the multi-cloth is removed. This makes it possible to penetrate the multi-fabric efficiently.
