2. Description of the Related Art Reflecting Japan's state of rapid economic development, countries around the world are strongly demanding deregulation measures for Japan's trade, targeting products in various fields and restricting imports and exports. Since it has been mitigated and it has entered the preparatory stage, various industrial fields have been forced to make various efforts to deal with it. Liberalization of agricultural products has also become an important target item, and fruits such as citrus fruits, cherries, and apples have already been completely liberalized, and those product farmers have entered into a competitive relationship with foreign products and the efforts of the parties concerned. We are accumulating enough results to compete with each other.

[0003] In the case of agricultural products and rice, due to the food situation peculiar to Japan, we have made inevitable attacks and defenses in response to requests from other countries, and although we have not reached full liberalization at present, we are close to gradual liberalization. It is assumed that in the future, we will have to move to full liberalization. Because of the urgent need to respond to such changes in the situation, the national institutions are strict, and the rice farmers directly affected by it are able to unite to compete against foreign rice. Efforts are being made to develop and cultivate high-quality varieties that can ensure quality and quantity, and excellent varieties of rice that are already tasty and resistant to diseases and pests and that are expected to generate sufficiently high profits are being introduced one after another.

On the other hand, in order to improve the efficiency of agricultural work, the development of the field base has been steadily progressed, and a large field with 3 sections and 1 section has been systematically integrated and organized so that a large machine can be introduced. A high production efficiency environment is beginning to be realized, and not only main agricultural work such as tillage, rice planting, harvesting, threshing, etc. but also auxiliary agricultural work in the production process such as disinfection and water quantity management is performed. Along with the review of mechanization, each agricultural machinery manufacturer continued to make inevitable efforts to improve the performance and size of these machines and facilities, gradually liberating from heavy labor and increasing the work rate. Is beginning to turn.

In the present invention, as a result of reviewing the reality of rice planting work in the transition of the environment of rice farming as described above, the following actual conditions are left unattended, and the reduction of agricultural work and the increase in profitability are achieved. Since I got the knowledge that everything was not done properly, I decided to grasp the impetus for developing and researching to solve it. In other words, as mentioned above, even if a rice farmer who had completed infrastructure development and introduced a large-scale rice transplanter with high performance and intended for efficient agricultural work, he raised the rice transplanter in anticipation of higher profitability. As a supplementary rice planting work to be performed later, while raining, he walked around the entire wide field again in a half-bent posture with his hips bent, and replanted the seedlings by himself in the position where the mechanical rice planting resulted in a missing plant. There is work left to do, which requires extra time and hard and modest effort.

[0006] However, in rice farming, which is mostly supported by part-time farmers, it is impossible to carry out the work as one would like even if he / she understands the necessity, and it should be one of the most important subjects of rice farming in the future. There are an extremely large number of rice farmers who have had to abandon measures to increase profits. So far, it was known that such an actual situation exists, but in reality, there is no particularly effective way to do so, and at the agricultural equipment manufacturer who is also responsible for one side, it is mainly the control system of the planting claw. However, the expected results have not been obtained so far, and it has been left to the remaining cultivation techniques of rice farmers and the mechanical operation techniques of rice transplanters. However, the efforts of those rice farmers are not always rewarded for the various fields, and as a result, there is more or less absent stock in the fields after planting the mechanical fields in any of the fields. It has happened.

According to the present invention, as a result of observing and analyzing the actual condition of the stock-out phenomenon in the equipment as one of the applicants who are engaged in rice farming and implement mechanical rice planting, finally, most of the causes are rice planting. It was planted in relation to the quality or tillage of the mud layer at the part of the planting nail that hits the planting path and the condition of the mud layer, rather than being derived solely from the mechanism of the planting nail of the machine or the mechanical operation technique. We found out the fact that the overturning phenomenon leading to the lack of stock or the lack of stock caused by the return of mud to the seedlings was caused, and we sought various ways to deal with them and conducted various trial and error. I've been repeating it. As a result, basically, it is possible to carry out the redevelopment of the soil mud layer that serves as a pathway for planting the seedlings with the planting nails and the restoration of the mud around the seedlings after they are planted. We have succeeded in completing and putting into practical use a planted seedling abscission prevention device for a rice transplanter consisting of the following new structure.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be clearly understood from the embodiments representative of the present invention shown in the drawings, the planted seedling abscission preventive apparatus in the rice transplanter according to the present invention is basically realized by the following configuration. To be done. That is, on the bottom surface of the float of the rice transplanter, at a position above the planting line of the seedlings by the planting claws, and in the proper position of the main part of the leveling, which is in front of the working space of the planting claws, a muddy crushing and pushing protrusion is provided. At the same place on the rear side of the same space where the operation of the planting claws is not hindered, the slender body part is used as a support part to maintain the optimum spacing to allow the planted seedlings to pass, and A planted seedling abscission preventive device in a rice transplanter, characterized in that a pair of mud pulling pieces, which are height-adjustable relative to each other so that they can pass near both sides of the root of the seedling, are formed protrudingly. is there.

The float is arranged in a most popular mat seedling type walk type rice planting machine or riding type rice transplanter by hanging it from just below the seedling placing table to the front and connecting the four-node link mechanism and the cam of the planting mechanism. 3 to 4 seedlings scraped by the planting claws that realize movement almost like a human hand when combined are planted in the soil mud layer to a certain depth (usually around 3 cm). It also functions to level the surface of the mud layer just before being planted. In order to fulfill its function, this float is usually
A flattened shape that is wider than the prescribed size between the planting muscles (usually fixed at 33 cm), and the side surface is formed into a sled structure, and the smoothing main part is connected to the rear of the flattening main part. A pair of left and right planting claws at intervals are used to scrape the required number of seedlings from the lower end of the seedling placing table by repeating the arc-shaped operation, and at a predetermined depth into the soil mud layer that has just been leveled by the previous main part of leveling. In order to enable planting, it consists of an elongated body part that is narrowly formed with securing a planting space on both sides.
It is shaped like a scoop with a wide handle, and the part that seems to be cut out on the left, right and left sides of the flattening main part is the planting claw working space.

The mud crushing and pushing protrusion is formed on the bottom surface of the flattening main portion of the float having the above construction, and is planted in the process of flattening the mud layer surface in the flattening main portion. Crush the mud left as a lump on the planting muscles to be planted with nails,
If you put it to the side or sink it to a predetermined depth or less, the subsequent planting of the seedlings with the planting claws,
It serves the function of preventing instability of planting by being disturbed by the mud mass and the situation of not being plugged on the mud mass, and thus can fulfill those functions. , A thin metal rod made of stainless steel or the like is bent, or a thin plate made of metal or plastic is vertically laid downward. It is desirable to form a plurality of or a plurality of protruding pieces within a predetermined width centered on the planting muscles of the seedlings, and the side shape of the seedlings crushes mud blocks,
Convenient to bounce off or push in, and to ensure that no additional resistance is applied to the forward movement of the float, the outline of a substantially triangular shape, elliptical shape, trapezoid, etc. that spreads backward in the traveling direction Should be

The mud crushing and pushing intruder is provided as a single part separately from the float in addition to being integrally formed with the float at the stage of manufacturing the rice transplanter in advance. It can be sold or provided separately from the rice transplanter, and can be detachably attached at the store or the farm that purchased it. The structure itself for detaching is It is not a particularly important constituent part of the invention, but may be attached by appropriately adopting a conventional means such as outside the structure as shown in the following embodiments, fitting, adhesion, screwing, or a combination thereof. It is enough if

On the other hand, the mud gathering piece has a function of gathering the soil around the seedlings planted at a predetermined depth in the soil mud layer by the planting claws to gather the soil around the seedlings. Being behind the space, the structure with the float elongated body part as a supporting part maintains an appropriate interval for passing the planted seedlings, about 5 cm, and also the planted seedlings. It is a structure that can be adjusted so that the height position from the float is in an optimum state so that it can pass near both sides of the root of the plant, and the pair of rice seedlings are arranged symmetrically on both sides across the planting muscle of the seedling. It is formed so as to project from the arrangement.

In view of its function, this mud gathering piece is a thin plate-like piece, and it is desirable that a pair of plane arrangements are spread forward in the float advancing direction. It has a frontal shape that is forcibly pressed downward in the soil mud layer and has a slightly "C" -shaped configuration.
It is arranged so as to project from the float to a predetermined lower position. Similar to the above-mentioned mud crushing and pushing intruder, this mud gathering piece is also formed separately from the float as an integral part or formed integrally with the float at the stage of manufacturing the rice transplanter in advance. It is also possible to make it detachable and attachable at a store or a farmer who purchased it separately from the rice transplanter. Hereinafter, some embodiments representative of the present invention shown in the drawings will be described in detail to help understand the technical idea included in the planted seedling abscission prevention device in the rice transplanter of the present invention.

Example 1 As seen from the bottom side of FIG. 1, the float F
2 is an overall perspective view showing a state of being assembled into
The same side view of FIG. 3 and the same rear view perspective view of FIG. 4 (therefore, the positions of the muddy crushing and pushing protrusions 1 and 1 are located inside the mud gathering pieces 2 and 2 displayed in front). In the present embodiment, the muddy crushing and pushing protrusions 1 and 1 can be clearly understood from FIG.
In addition, the mud gathering pieces 2 and 2 are examples in which they are preliminarily incorporated and integrated at the stage of being provided as the rice transplanter M. First of all, the muddy crushing and pushing protrusion 1 has three protrusions 11, 11, 11 which are made of stainless steel thin rods and are bent and formed in a side shape of a substantially inverted "H" shape. The protrusions 11 are integrally formed on the attachment substrate 12 so as to be positioned on the seedling planting muscle L, and the attachment substrates 12, 12 are located in front of the planting claw working space F3. A pair of left and right are fixed to the bottom surface of the smoothing main body portion F1 by means of screws which also use an adhesive.

On the other hand, the mud pulling piece 2 is formed of a thin stainless steel plate having a side surface shape and, as shown in the bottom view of FIG. 2, is symmetrical to the rear of each planting claw working space F3, F3. The arrangement is a position where it does not interfere with the operation of the planting claw M1 and the spacing between the two is across the planting muscle L of the seedling, and the distance between them is about 5 cm at a narrow position. With the arrangement that the side is the float forward direction),
Moreover, as shown in the rear view of FIG. 4, the protrusions are formed in a posture of a substantially “C” shape in which the upper side is slightly narrowed in the front view.
The projecting formation of the mud drawing pieces 2 and 2 is performed by connecting the connecting pipe 2 to the upper ends of the support shaft rods 21 and 21 that are vertically installed from the mud drawing pieces 2.
2 and 22 are integrally formed, the lower ends of the inverted U-shaped rods 3 and 3 are inserted from the upper end openings of the connecting pipes 22 and 22, and the support rods 21 and 21 are firmly fixed by the fixing screws 23 and 23. , The pair of mud pulling pieces 2, 2 which are relatively faced with each other are arranged in a protruding manner in a predetermined posture. Therefore, the support rods 21 and 2
It is possible to change the postures of the mud pulling pieces 2 and 2 by appropriately rotating and fixing 1 in the horizontal plane.

The U-shaped rods 3 and 3 in which the mud pulling pieces 2 and 2 are arranged so as to project downward are provided with arm rods 41 of the fixing member 4 having the upper surface of the float F as a support portion in advance, and sheath rods 42 at both ends. , 4
2 is slidably inserted in the upper and lower parts of the sheath rod 42, 42.

Since the heights of the rods 3, 3 themselves are adjustable, the sheath rods 42, 42 of the falling U-shaped rods 3, 3 are formed.
The fixing position with respect to is properly adjusted and the adjusting screws 43, 43 are tightened, and the mud gathering pieces 2, 2 are positioned below the float F and in the optimum position near the seedling plant P planted by the planting claw M1. I will fix it. As a result, the mud gathering pieces 2 and 2 can always be formed protrudingly at the optimum position according to the type of the float F and the situation of the field, even if the manufacturer or model of the temporary rice transplanter is changed.
In the figure, reference numeral 44 denotes a hook screw for fastening and fixing the front end of the fixing member 4 to a mounting portion F4 for the seedling placing table M2 which is integrally formed with the float F.

[0017]

[Example 2] Unlike the example 1 described above, the example shown in the whole perspective view showing the float F in FIG. This is an example in which it can be freely attached, and in addition, the configuration of the muddy crushing and pushing protrusion 1 is changed. In this example, the mud crushing and pushing combined protrusion 1 is formed from a triangular thin plate whose side surface extends rearward on the attachment substrates 12 and 12 each having a holding portion 13 for holding the side edge of the float F and a mounting screw 14. It is made of a plastic member having a configuration in which three of the protruding portions 11, 11, 11 are arranged side by side in parallel, and the fitting state of the holding portion 13 on the side of the float F is adjusted to adjust the protruding portion 11,

On the other hand, the mud pulling pieces 2 and 2 are integrally formed with the connecting rod / sheath rods 24 and 24 at the upper ends of the spindle rods 21 and 21 which are vertically hung from the mud pulling piece 2. The connecting pipe / sheath rods 24, 24 are previously welded to both ends of the arm rod 41 of the fixing member 4 having the upper surface of the float F as a support portion and inserted into the lower ends of the inverted U-shaped rods 3, 3 which are fixed to each other, and the connecting pipes The fitting condition of the dual-purpose sheath rods 24, 24 to the falling U-shaped rods 3, 3 is appropriately adjusted in the vertical direction, and the mud-shifting pieces 2, 2 are below the float F and are planted by the planting claw M1. The adjusting screw 2 should be placed in the optimum position near the seedling P.
After the screws 5 and 25 are tightened and fixed, the mud-sucking pieces 2 and 2 are always formed in a projecting manner at the optimum position according to the type of the float F and the situation of the field. Also, the connecting rod and sheath rod 2
If the fitting condition of the 4, 24 to the inverted U-shaped rods 3, 3 is rotationally adjusted in the horizontal plane, it is possible to adjust the expansion angle of the pair of mud gathering pieces 2, 2 which are relatively facing each other. .

The structure for attaching / detaching the mud gathering pieces 2, 2 to / from the float F uses the attachment / detachment of the fixing metal fitting 4 itself attached to the float F, that is, the attachment portion F4 for the seedling stand M2 and the rear end portion of the float F. In addition to releasing the fixed structure, the angle piece 45 with the fixing metal fitting 4 as an attachment part is attached or detached, and the falling U-shaped rod 3 is hung at both ends from the arm rod 41 supported by the angle piece 45, and integrated. The adjusted front and rear adjustment plate 47 is attached to the adjustment screw 49.

By adjusting the position of, the attachment to the float F having a different shape and structure and the attachment to the float F having a different operating position of the planting claw F2 in the planting claw space F3 can be determined at the optimum position. .

[0020]

[Effects] The planting seedling abscission preventive device for the rice transplanter of the present invention, which has the above-described configuration, is used as shown in FIG.
However, in order to prevent the vehicle body from tilting due to the unevenness of the traveling tiller surface, the traveling wheel M3 in which a vertical adjustment device by hydraulic control is incorporated keeps the vehicle body horizontal, and when traveling forward at a predetermined speed, The surface of the soil mud layer A is leveled by the float F lowered according to the depth of the soil mud layer A, and a pair of left and right mud lumps are provided at predetermined positions of the flattening main body portion F1 of the float F. The crushing and pushing combined use lugs 1 and 1 crush or bounce off the mud mass remaining on the planting line L in the leveled soil mud layer A and within a predetermined width around it, Alternatively, as a result of sinking to a depth that does not hinder planting, the seedlings P that are subsequently planted by the planting nails M1 are reliably inserted at their roots to a predetermined depth, and mechanical rice planting proceeds reliably.

When the float F moves forward with respect to the planted seedling P, this time, as shown in the enlarged perspective view of the main part of FIG. 6, behind the planting claw working space F3 of the float F,
The earth pulling pieces 2, 2 projectingly formed by using the elongated body portion F2 of the float F as a support portion pass through the seedling P while sandwiching the seedling P with the seedling P just at the center position. that time,
Since the height and the posture of the mud gathering pieces 2 and 2 are adjusted in advance so as to pass the vicinity of the plant of the seedling P that has been planted in advance, the soil around the plant that has escaped by the plunging of the planting claw M1 is removed. , It will be gathered from the surroundings and lightly compacted, and the mud will be collected very conveniently in the plant of the seedling P after passing, and the seedling P will float up or become overturned. As a result of the reliable prevention, the stock stall phenomenon is almost eliminated from the field after the mechanical rice planting, and the need for subsequent supplementary planting work can be eliminated.

Particularly, in the embodiment 1 of the present invention, since the planted seedling abscission preventive device is installed in advance at the factory shipment stage, it can be used as a rice transplanter immediately after purchase by a farmer. , One-by-one mud crushing and pushing lug 1,1
Also, it has a feature that it does not need to use nerves for adjustment and attachment according to the planting muscles L of the mud pulling pieces 2, 2 and, on the other hand, as in the second embodiment, it can be used at a store or a farmer. Although the one that is worn on the table leaves the troublesomeness of its attachment, it has the characteristic that it can be attached and used on any rice transplanter already purchased, and this type of equipment has become popular. It will be very helpful to you.

As described above, the planted seedling abscission preventive device in the rice transplanter of the present invention has no particularly effective means until now.
It is possible to implement efficient rice planting without the need for supplementary planting work by preventing the occurrence of the stock stall phenomenon as much as possible in response to the stock stall phenomenon, which has relied solely on the hard labor of farmers. In addition to exhibiting the above-mentioned characteristics, it has an advantage that it is configured with a relatively simple structure, is easy to manufacture and can be provided at low cost, and can be widely spread to rice farmers. Therefore, it is expected that it will be greatly welcomed by future rice farmers who have to make a little profit in the face of severe agricultural circumstances.
