Description

Description: TECHNICAL FIELD The present invention comprises a multi-sheet forming apparatus that automatically forms a multi-sheet on a rice field by spraying on the rice field and chemically reacting with water or air. Related to rice transplanters.

Conventional technology and problems to be solved When planting seedlings, if only the seedlings are protruded and the entire rice field is covered with a vinyl sheet, etc., weeds can be prevented from growing and cultivation management after planting can be simplified. In recent years, research has been conducted on paddy rice cultivation by a new method called mulching using vinyl sheets and other sheets, and planting seedlings with a rice transplanter from a sheet laid on the rice field has recently been studied. Various studies have been made on so-called multi rice transplanters.

However, since a synthetic resin film, such as a vinyl sheet, is used as a covering material (multi-sheet) for the rice field, the side edges of adjacent sheet materials should be aligned when laying the rice field, Such as cutting
It is necessary to pay attention to sheet alignment and headland treatment, and it is necessary to collect multi-sheets laid on the rice field after harvesting, and not only does it require a lot of time and labor to collect it, Since the recovered multi-sheet is almost impossible to reuse, it has to be treated by incineration, and there is also a problem of secondary pollution due to incineration.

Means for Solving the Problems The present invention has solved the above-mentioned problems by being configured as follows.

That is, a seedling rest, a planting rod, a planting portion composed of a float or the like is provided at the rear portion of the traveling machine, and a film forming material or a material obtained by blending the film forming material or a desired additive such as a fertilizer or a drug with the planting portion. A rice transplanter equipped with a multi-sheet forming device, wherein a multi-sheet forming device for spraying on a rice field is provided, and a spray pipe of the multi-sheet forming device is vertically installed between adjacent planting rods. is there.

Since the rice transplanter equipped with the multi-sheet molding apparatus according to the present invention is configured as described above, when the seedling is sprayed on the rice field by the multi-sheet molding apparatus while seedlings are planted on the rice field with the planting rod, The film-forming material reacts with the moisture, air, etc. in the field, and a film-shaped multi-sheet is automatically formed on the rice field.

An embodiment of the present invention will be described with reference to the drawings. In the drawings, a riding type rice transplanter equipped with a fertilizer is illustrated. That is, a drive case 1, a planting rod 2, a seedling mounting table 3 and a float 4 are provided behind a traveling machine body 5 having front wheels 19 and rear wheels 20.
The left and right side ends of the three floats 4 provided in the lateral direction are provided at positions sliding on the wheel marks formed immediately after the rear wheel 20. . Fertilizer tanks 7 containing paste-like fertilizer are mounted on both left and right sides of a bonnet 6 provided at the front of the traveling machine body 5, and the fertilizer in the tank 7 is fed in parallel with the planting of the seedlings by the planting section A. , Fertilizer pump 8, suction hose 9, discharge hose 10
Through the fertilizer application nozzle 11, lateral fertilization is performed to a predetermined depth in the soil.

A multi-sheet forming apparatus B is mounted on the drive case 1 of the planting section A via a stay 12. Reference numeral 13 denotes a tank that stores the film forming material, and the tank 13 contains water,
A powder of a film-forming material (a water-curable resin, an oxidation-curable resin, a photocurable resin, a high-grade aqueous resin, etc.) that forms a film-like film in response to air or light is contained. As these film-forming materials, for example, polyvinyl alcohol (popal), methyl cellulose (methocel), ethyl cellulose (ethocel), carboxymethyl cellulose (CMC) (sodium cellulose glycolate) and the like can be appropriately selected. However, those which react with water or the like to form a film having high toughness and elasticity are desirable. Further, the film-forming material may contain a chemical such as a fertilizer component or a herbicide, if necessary. Further, it is also possible to mix a desired dye such as a black color with the film forming material. Numeral 14 is a scatter pipe protruding from the tank 13 in the state of being close to the ground. The scatter pipe 14 is vertically provided at a rear portion of the float 4 between the adjacent planting rods 2, 2, and is disposed inside the tank 13. The stored film forming material is fed out by a predetermined amount by a feeding mechanism (not shown) interlocked with the power transmission system of the planting section B, and is sprayed on the rice field by the spraying pipe 14.

2 to 4, the fertilizer tank 7 is vertically separated by a flexible separation membrane 15 which can move up and down in response to the increase and decrease of the internal fertilizer. To
A liquid b, which is configured so as to be capable of separately storing a balancing liquid b such as water and the like at an upper portion thereof, and which is communicated with the upper chamber of the fertilizer tank 7 through a connection pipe 16 at a position substantially at the center of gravity of the traveling machine body 5
A sub-tank 17 for storage is arranged to keep the inside of the fertilizer tank constant to prevent the front-rear balance of the aircraft from fluctuating due to changes in the remaining amount of fertilizer in the tank. is there. That is, when the amount of fertilizer a in the fertilizer tank 7 is large, the upper liquid b is pushed up by the separation membrane 15 and returned to the sub-tank 17 side, and when the remaining amount of the fertilizer a decreases, the liquid b is released from the sub-tank 17 It is configured to move to the upper chamber of the tank 7, and the fertilizer tank 7 and the sub-tank 17 are provided with a height difference so that the liquid b can flow in and out smoothly. With this configuration, the accommodation amount in the fertilizer tank 7 is always kept constant, so that there is no fluctuation in the longitudinal balance of the body with respect to a change in the remaining amount of fertilizer during the operation, and the traveling performance is improved.

The sub-tank 17 can also be used as a fertilizer tank of a two-stage fertilizer planting machine that fertilizes fertilizers having different components in the remaining layer and the deep layer of the field.

Fig. 5 shows a conventional multi-sheet S in the multi-ing farming method, in which a grid-like reference line 18 is provided in advance so that the planting position can be seen at a glance. There is no reference for the attachment position
And there was an inconvenience of wide and narrow variation between w
By providing the reference line 18, seedlings can be planted at regular intervals in the vertical and horizontal directions. Although not shown, the reference line 18
Instead of a point display, a plant display position may be displayed as a point.

Now, when the rice transplanter having the above configuration is run through the paddy field, seedlings are planted on the rice field by the planting rod 2, and the fertilizing nozzle
The fertilizer is supplied into the soil by 11 and the film-forming material contained in the tank 17 is sprayed from the spray pipe 14 to the rice field by the multi-sheet forming apparatus B in parallel with the planting and fertilization of these seedlings. Thus, the film-forming material automatically reacts with water, air, light, or the like in the field, depending on whether it is a water-curable resin, an oxidation-curable resin, or a light-curable resin, and automatically forms a film-shaped multi-sheet on the rice field. It is what will be formed.

At this time, since the rice transplanting operation is particularly performed in a paddy field, it is desirable to use a water-curable resin which forms a film having high toughness and elasticity by reacting with water as the film-forming material.

In the case where the multi-sheet forming apparatus B is mounted on the planting section A as in the illustrated example, the film forming material feeding mechanism and the like can be driven in direct linkage with the power transmission system of the planting section B. The transmission mechanism is simplified, and the
Also, the multi-sheet forming apparatus B can be arranged compactly.

As described above, the film-forming material contained in the tank 17 is sprayed from the spray pipe 14 onto the rice field in parallel with the planting of the seedlings by the multi-sheet molding apparatus B, so that the multi-sheet is planted on the rice field simultaneously with the planting of the seedlings. The work efficiency is further enhanced because it can be automatically formed, but in particular, the film forming material is sprayed to a position close to the ground by the spraying pipe 14, so that scattering by wind etc. is prevented and appropriate. And the float 4 on the left and right is leveled on the wheel traces and the film forming material is sprayed on the field surface in the leveled state, so that the film forming material is supplied to the groove of the wheel traces. Thus, useless loss can be prevented. In particular, since the spraying tube 14 is vertically provided between the adjacent planting rods 2, it is ensured that the film-forming material is sprayed around the seedlings, and the film-like material is completely surrounded by the planting seedlings. Can be formed as one continuous sheet over the entire surface of the rice field.

Therefore, unlike the conventional mulching farming method, the step of laying the vinyl sheet on the rice field is unnecessary, so that the troublesome work of aligning adjacent sheet side ends or cutting the sheet at the headland is eliminated. It is resolved at once,
Workability is significantly improved. Further, the multi-sheet can be easily formed over the entire surface of the rice field without being affected by field conditions such as a curved field and an uneven rice field.

Since the multi-sheet formed as described above is harvested and then plowed as it is and mixed with the soil, the work of collecting the multi-sheet becomes unnecessary. The problem of the next pollution will be solved at once.

In the case where a chemical such as a fertilizer component or a herbicide is added to the film forming material, it is possible to save labor for fertilizer spraying and weeding as much as possible.

Effects of the Invention Since the present invention is configured as described above, the film-forming material can be sprayed on the rice field by the spray pipe 14 in parallel with the planting of the seedlings by the multi-sheet forming apparatus B, and the film-forming material is This automatically reacts with water or the like to form a multi-sheet on the rice field. Since planting of seedlings and formation of the multi-sheet can be performed at the same time, work efficiency can be further enhanced.

Since the multi-sheet forming apparatus B is mounted on the planting section A, its transmission mechanism is simplified, and the scatter tube 14 may be short, so that the multi-sheet forming apparatus B can be arranged compactly. With, in particular,
The spray tube 14 is provided vertically between the planting rods 2 to ensure that the film-forming material is spread around the seedlings, and the film-shaped multi-sheet is completely surrounded by the planting seedlings. Since it can be formed into a single continuous sheet over the entire rice field, the growth of weeds is reliably suppressed, and the cultivation management after planting can be simplified.

Therefore, unlike the conventional multi-ing farming method, there is no need to lay a vinyl sheet on the rice field, and the troublesome sheet processing of joining adjacent sheet side edges or cutting the sheet at a headland is required. Not only does not need to be paid attention to, but also the multi-sheet can be easily formed over the entire surface of the rice field without being affected by field conditions such as a curved field and an uneven field.

Moreover, the multi-sheet formed on the rice field, after mowing,
By tilling as it is with a rotary tilling device and mixing it into the soil, there is no need to collect the multi-sheets at all, so that significant labor savings can be achieved. In addition, by blending desired additives such as a fertilizer component and a herbicide into the film-forming material, the multi-sheet can be used as an original fertilizer or a herbicide, and the cultivation effect can be further enhanced in conjunction with labor saving of work.
