Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a seedling placing table in a rice transplanter in which mat seedlings are sequentially supplied to an inclined seedling placing table for planting work.

[Conventional technology]

Generally, the seedling placing table that reciprocates left and right is installed in an inclined shape, and the mat seedlings placed on the seedling placing table are divided into unit planting plants from the lower end of the seedling placing table and planted on the paddy field to proceed with the planting work. Along with this, there is known a rice transplanter in which mat seedlings are reduced, and when the amount becomes less than a predetermined amount, new mat seedlings are sequentially replenished from above the seedling placing table to carry out seedling splicing.

[Problems to be solved by the present invention]

However, conventionally, when mat seedlings on the seedling placing table are reduced and seedlings are spliced, even if the seedlings on the seedling placing table are deformed, new mat seedlings are supplied from the upper end side of the seedling placing table. Since the seedlings are forcibly spliced, the density of the seedlings will not be uniform at the joints of the mat seedlings.Therefore, there will be a problem in that the number of plantings will vary when split into unit plantings and planted on the rice field. there were.

The present invention was devised to solve the above-mentioned problems, and when mat seedlings on the seedling mounting table are reduced and seedlings are spliced, new mat seedlings are supplied from the upper end side of the seedling mounting table. By doing so, the bottom edge of the mat seedling is automatically linearized before the seedling is spliced, so that the planting work can be done in an orderly manner without causing variations in the number of plantings. The purpose is to provide.

[Technical means for solving problems]

In order to solve the above-mentioned problems, the technical means taken by the present invention is to provide a slanting seedling mounting table that reciprocates left and right, and a mat seedling placed on the seedling mounting table is united from the lower end of the seedling mounting table. In a rice transplanter that is divided into planting stocks and planted on a rice field, a seedling feeding body for feeding mat seedlings downward is provided on the lower end side of the seedling placing table, and a seedling placing body is provided near the above seedling feeding body. A convex portion that is orthogonal to the vertical rib in the seedling feeding direction formed on the table and that protrudes higher than the vertical rib is provided, and the convex portion supports the mat seedling supplied to the seedling mounting table, and the lower edge It is characterized in that it is configured so that the seedlings are supplied to the seedling feeder side after being prepared.

[Function of device]

Therefore, according to the present invention, the mat seedlings placed on the inclined seedling placing table are divided into unit planting plants from the lower end of the seedling placing table and planted on the rice field. When the mat seedlings are reduced to the vicinity of the seedling feeder provided on the lower end side of the seedling placing table as the planting work progresses, if new mat seedlings are replenished from the upper end side of the seedling placing table, A convex portion that is orthogonal to the vertical ribs in the seedling feeding direction formed on the table and that protrudes higher than the vertical ribs supports the mat seedlings once to stop the sliding of the seedlings and to reciprocate left and right. Since the bottom edge of the mat seedlings is aligned linearly by vibration, etc., the mat seedlings are supplied to the seedling feeder side over the convex part, so the mat seedlings are deformed at the joints of the seedlings and forcibly spliced. There is no. Therefore, even if the mat seedlings are divided into unit plantings and planted on the paddy field, the planting work can be done in an orderly manner without causing variations in the number of plantings.

〔Example〕

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
In FIG. 1 to FIG. 5, reference numeral 1 is a two-row planting paddy rice transplanter, in which an operating handle 3 is extended obliquely rearward and upward from a machine body equipped with an engine 2. Reference numeral 4 denotes a seedling placing table that is installed in an inclined shape along the operation handle 3 and reciprocates left and right by a drive mechanism 5 to move the mat seedlings placed on the seedling placing table 4 to the seedling placing table 4 A planting claw 6 provided in front of the seedling take-out port at the lower end divides each unit planting stock and plants it on the rice field.

The seedling placing table 4 is divided into left and right by a partitioning vertical rib 7 so that mat seedlings can be placed respectively.
Vertical ribs 8, 8 ... In the seedling feeding direction, on which the mat seedlings slide, are formed in parallel on the bottom surface of the seedling mounting table 4. Reference numeral 9 denotes a seedling feeder including a conveyor belt 10 provided on the lower surface of the seedling placing table 4, and the conveyor belt 10 is conveyed through an opening 11 formed in the seedling placing table 4 corresponding to the seedling feeder 9. The protrusion 10a projects to convey the mat seedling on the seedling mounting table 4 downward.

Further, in the vicinity of the upper part of the opening 11, a horizontal convex portion 12 which is orthogonal to the vertical ribs 8, 8 ... And protrudes higher than the vertical ribs 8, 8 ... Is formed. The mat seedling a supplied from the upper end side of 4 is once supported by the convex portion 12 as shown in FIG. The bottom edges of the mat seedlings are aligned in a straight line, and then the mat seedlings are fed to the seedling feeder 9 side which protrudes from the opening 11 by overcoming the convex portion 12.

FIGS. 6 to 10 show a combination of two-row planting seedling mounts to easily form a four-row or six-row planting seedling mount. That is, thick portions 14, 14 ... having a width W ₂ narrower than the width W ₁ of the base end portion are formed at a plurality of positions of the partitioning vertical ribs 13 of the seedling placing table 4, and bolts, etc. are formed in the thick portion 14. An insertion hole 16 for inserting the tightening tool 15 is provided. When the seedling placing table 4 is combined, the vertical ribs 13 for partitioning located on both sides of the seedling placing table 4 are provided by using the cutter b as shown in FIGS. 9 and 10.
If the cutting is performed on the outside of the center line and then connected through the tightening tool 15 inserted in the insertion hole 16, the vertical ribs 13 for partitioning formed in the connecting portion can always have the same width, and the thickness can be increased. Department
Since they are connected with each other, even a combination of the two-row planting table 4 can have a strong structure. Moreover, the tightening tool 15 inserted through the thick portion 14 of the fox will not interfere with the mat seedlings that slide down on the seedling mounting table 4.

Further, FIGS. 11 to 12 show that, in a multi-row seedling mounting table formed by combining plates of the same shape, an elastic body 19 is provided at the connecting portion of the ribs 18 provided on both sides of the plate 17. Thus, the scraper 20 fitted in the rib 18 is prevented from rattling. That is, on the lower end side of the seedling mounting table, the tip is engaged with the rising portion of the seedling receiving plate 21, and the base end side is ribbed
The scraper 20 inserted into the inside of the seedling 18 is provided so that the scraper 20 moves laterally along with the seedling mounting table that reciprocates left and right to clean the upper surface and the inner side surface of the seedling receiving plate 21, but the elastic body 19 is used as the scraper. Since 20 is pressed, rattling of the scraper 20 can be reliably prevented without separately providing a plate spring or the like for removing rattling.

In the above-mentioned configuration, if the mat seedlings are placed on the seedling placing table 4 which is now installed in an inclined shape along the operation handle 3,
The planting claws 6 divide the mat seedlings into individual planting stocks from the seedling take-out port at the lower end of the seedling mounting table 4 and plant them on the rice field. Then, at the time of seedling splicing in which the mat seedlings have decreased to the vicinity of the opening 11 as the planting work progresses, if new mat seedlings are replenished from the upper end side of the seedling mount 4, vertical ribs 8 in the seedling feeding direction, The mat seedlings that slide on the sliding surface 8 and are slid down are temporarily supported by the convex portions 12 in the left-right direction provided near the upper portion of the opening 11. Then, the bottom edge of the mat seedling is linearly aligned by the convex portion 12 by the vibration of the seedling mounting table 4 that reciprocates left and right, and then the convex seed portion 12 is passed over and supplied to the reduced mat seedling. Since the seedlings are spliced, the mat seedlings will not be deformed at the joints of the seedlings and forced to be spliced. Therefore, when the planting claws 6 divide the mat seedlings into unit plantings and plant them on the paddy field, the number of plantings does not vary and the planting work can be performed in an orderly manner. Moreover, the convex portion 12 can be used as a reinforcing member for the seedling placing table 4 in which the opening 11 is formed.

Moreover, in the case shown in FIGS. 6 to 10, the seedling mounting table 4 for two-row planting is used.
Just by combining, 4 without reducing the strength at all
A seedling stand such as a row plant or a six-row plant can be easily manufactured, and the number of parts is reduced, and the manufacturing cost can be greatly rationalized.

Further, in the one shown in FIGS. 11 to 12, rattling of the scraper 20 can be easily prevented, so that the lateral displacement of the mat seedling due to the left-right reciprocating movement of the seedling mounting table is reduced, and the seedling scraping by the planting claw 6 is performed. The performance can be improved.

[Effect of device]

In short, the present invention provides that the seedling placing table that reciprocates left and right is provided in an inclined manner, and the mat seedlings placed on the seedling placing table are divided from the lower end of the placing table into unit planting plants and planted on the rice field. In the rice transplanter, a seedling feeding body for feeding mat seedlings downward is provided on the lower end side of the seedling mounting table, and in the vicinity of the upper part of the seedling feeding body, perpendicular to the vertical ribs in the seedling feeding direction formed on the seedling mounting table. Further, a convex portion protruding higher than the vertical rib is provided, and the mat seedlings supplied to the seedling mounting table are configured to be supported by the convex portion and the lower end edges are aligned before being supplied to the seedling feeder side. Therefore, when the mat seedlings placed on the seedling placing table are reduced to the vicinity of the seedling feeding body, if the mat seedlings are supplied from the upper end side of the seedling placing table, the mat seedlings that slide down the inclined seedling placing table Is a convex shape that is orthogonal to the vertical ribs formed on the seedling table in the seedling feeding direction and that protrudes higher than the vertical ribs. Once the mat seedlings have been aligned, the bottom edges of the mat seedlings are aligned to form a straight line due to the vibration of the seedling mounting table that reciprocates left and right, and after overcoming the convex portion, the seedlings are spliced onto the reduced mat seedlings. Therefore, the mat seedlings are not deformed at the joints of the seedlings and are not forcibly spliced. Therefore, the planting work can be carried out in an orderly manner without causing variations in the number of plants to be planted on the paddy field by dividing the seedling mounting base into unit plantings.
