Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seedling stand in a transplanter for scraping and planting mat seedlings.

[0002]

[Prior art]

 Conventionally, seedling mounts for rice transplanters for paddy fields or transplanters for upland fields are provided with an inclination in the front-back direction of the machine body, and a wide protruding belt is transferred between the drive roller and the driven roller into one notch hole. As shown in the figure, a vertical feeding device is constructed so that it is stretched, and the drive rollers of this vertical feeding device are forced to rotate at both end portions where the seedling mounting table laterally feeds and reciprocates in the left-right direction of the machine body. The mat seedlings are fed vertically for each stock.

[0003]

[Problems to be solved by the device]

 However, the belt in the above-mentioned conventional vertical feeding device is stretched on each of one or two rollers laterally provided on the left and right sides of the width of one unit of the seedling placing table on which one mat seedling is placed. Therefore, if there is a deviation in the type of mat seedlings such as the soil or the posture of insertion into the seedling mounting table, the mat seedlings are scraped off by the planting claws and one side end thereof is removed as shown in FIG. Is fed vertically to the scraping surface A while the protruding end B is left, and the protruding end B abuts the apron to give a vertical feed resistance and a slip is provided between the belt and the driving roller. Will occur. As a result, the vertical feed amount of the scraping surface A that should be scraped up to the next stroke is reduced, and the amount of seedlings scraped by the planting claws is reduced, resulting in a lack of stock and disturbed planting posture. There was a problem that caused it.

The present invention solves the above-mentioned conventional problems, and at the same time, the mat seedlings placed on the seedling placing table under various conditions are always properly vertically fed to perform a good planting work. It is intended to provide a seedling stand in.

[0005]

[Means for Solving the Problems]

 The seedling mounting table in the transplanting machine of the present invention for achieving the above object has a notch hole in the bottom plate of the seedling mounting table that reciprocates left and right, and in which a vertical feeding device in which a belt is stretched between a driving roller and a driven roller is also provided. In a transplanter configured to be formed and scrape and plant seedlings with a planting claw located below the seedling mounting table, the belt of the vertical feeding device is divided into a plurality of parts in the cutout hole to operate. It is configured so as to be adjacent. In addition, it is characterized in that the driving roller and the driven roller are separately provided for each of the plurality of belts that are adjacently provided by being divided.

[0006]

[Work]

 In the present invention, two belts 10a, 10b on the left and right are provided side by side in one notch hole 12 formed in the seedling placing table 3. Therefore, when the mat seedling M having the unpeeled protruding end B is vertically fed, as shown in FIG. 4, the protruding end B and the apron 8 butt on the left belt on the protruding end B present side. As a result, the left belt 10b provided adjacent to the driving roller 9a and the driven roller 9b (FIG. 1) slips vertically to make it impossible to feed vertically, while the adjacent left belt 10b bends the side portion of the protruding end B and is flush with it. Since it is fed vertically to the scraping surface C and is molded, the seedlings are properly scraped by the planting claws 7 at all times.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a riding-type rice transplanter, which is a rear part of a machine base 2 having wheels 1a, a driver's seat 1b, etc. 4 is vertically movable by an elevating and lowering transmission mechanism 5, the seedling placing table 3 is laterally fed and reciprocated by a well-known mechanism, and the feeding surface is exposed through a notch hole 12 formed in the seedling placing table 3 so as to be exposed vertically. By means of the device 6, the mat seedlings M are vertically fed and planted by the planting claws 7 to plant seedlings one by one on the ground.

The seedling mounting table 3 has a front end slidably mounted on an apron 8 and is supported by a transmission case 4b with a sled 4a in a front-rear-lower position, and the seedling-mounting surface 3a is partitioned by a partition wall. The mat seedlings M for each unit are divided by 3b, 3b ... so that they can be placed, and a drive is provided on the left and right with a predetermined space H (slightly larger than the space between the cutout holes 12) in the widthwise direction of the lower part. As shown in FIG. 3, belts 10 and 10 having a wide projection 10c are formed in the left belt 10a and the right belt 10b in a two-divided manner between the roller 9a and the floating roller 9b, and the belts 10 and 10 are formed in one notch hole 12. It is stretched in parallel.

Therefore, the left belt 10a and the right belt 10b, which are provided as a set in the one notch hole 12 provided in the seedling placing table 3, are either the belt 10a or the belt 10a when a seedling feeding resistance is applied to either belt. A "differential longitudinal feed" occurs in which a slip occurs between the roller 10b and the rollers 9a and 9b and one belt operates in the one notch hole 12 with respect to the other belt to cause a difference in the vertical feed amount. It is configured to be possible.

Reference numeral 11 is a drive shaft to which a drive roller 9a is fixed, and is forcedly rotated by the transmission case 4b at the left and right reciprocating ends of the seedling mounting table 3 which are horizontally fed so that the seedling mounting table 3 is vertically fed every one share. Is configured. The drive roller 9a and the driven roller 9b may be divided on the drive shaft 11 so as to be individually opposed to the left and right belts 10a and 10b. At this time, the divided drive rollers 9a and 9a are separated. If a torque limiter mechanism (not shown) is installed between the drive shaft (not shown) and the drive shaft 11 so as to cause a slip between the two, a more reliable vertical feed can be achieved. is there.

As shown in FIG. 4, the longitudinal feeding of the mat seedling M according to the present invention having the above-described structure is performed by removing the matted seedling M scraped off with the protruding end B left to be the scraping surface A on the seedling placing table 3. At the end of the feed, when the drive roller 9a rotates to feed the belt 10 in the vertical direction, the protruding end B abuts the apron 8 to provide a vertical feed resistance. In this case, of the left belt 10, the left belt 10a causes a slip between the drive roller 9a and the driven roller 9b while the protrusion 10c on the surface thereof meshes with the mat seedling M, and substantially prevents the vertical feed. On the other hand, the right belt 10b and the right and left belts 10a and 10b of the right belt 10 which are adjacent to each other are differentially adjusted in accordance with the vertical feed resistance of the mat seedling M, and the vertical feed is equivalent to one share. .

Therefore, the scraping surface A forms a flat scraping surface C having the same linear shape as the side surface of the projecting end B is slightly buckled and bent as shown by a dotted line. Become. From this state, the planting claw 7 starts scraping, so that the occurrence of stumps and the like is prevented, and a proper amount of planting can always be carried out in an orderly manner.

[0013]

[Effect of device]

 Since the present invention is configured as described above, when an unscraped protruding end occurs at the end of the mat seedling during the planting work, the protruding end does not reduce the vertical feed amount and the left and right sides are adjacent to each other. The belt is operated so that the scraping surface is always flush with the specified amount of vertical feed, so the appropriate number of seedlings per plant is suitable for each seedling with no missing or disturbed seedlings. Can be planted accurately.
