Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a transplanter for transplanting long mat seedlings.

[0002]

2. Description of the Related Art Generally, mat seedlings of this type are seedling-grown using a seedling box of approximately standardized dimensions (width 30 cm × length 60 cm), and then placed on a seedling table of a transplanter. Although transplanted to the field, the mat seedlings of the standard size are formed to a length that allows several sheets to be placed in series on the seedling mounting table,
There was a disadvantage that the frequency of transporting the seedlings at the time of replenishing the seedlings was not allowed, and the frequency of scraping the seedlings at the joint was increased.

[0003]

Therefore, a long mat seedling that is longer than the standard mat seedling and does not greatly exceed the length of the seedling mounting stand is formed. It is conceivable to place it on a cell and transplant it. However, when the long mat seedlings are placed on the seedling table in a planar manner, the frictional resistance between the long mat seedlings and the seedling mounting table increases, and the seedling feeding load of the vertical feed belt increases. Therefore, there is a possibility that seedling failure may occur due to slippage of the vertical feed belt or the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve these problems in view of the above-mentioned circumstances, and a long mat seedling is lowered downward along a seedling mounting surface. A seedling platform for guiding, a longitudinal feed belt for forcibly feeding the back of the long mat seedling guided by the seedling platform, and an appropriate number of long mat seedlings guided to the lower end of the seedling platform. In a transplanting machine having a transplanting nail for scraping and transplanting a seedling of a book to a field, when the seedling mounting table is provided with a rotary seedling holding device for pressing a long mat seedling from the front side, the position of the vertical feed belt facing the And a seed presser that rotates with the forced feed of the vertical feed belt is disposed, and the rotational force of the seed presser is transmitted to the non-opposing position of the vertical feed belt and is disposed at the position. It is characterized in that the seedling holding device is forcibly rotated. In other words, the long mat seedlings can be forcibly fed even at the non-opposite position of the vertical feed belt, so that the seedling feed load of the vertical feed belt can be reduced and good seedling feed can be performed. When the power is separately secured to forcibly rotate the seedling presser disposed at the non-opposing position of the feed belt using the rotational force of the seedling presser disposed at the position opposite to the vertical feed belt. Thus, the structure can be simplified as compared with the case of FIG. Also, a seedling mounting table for guiding the long mat seedlings downward along the seedling mounting surface, and an appropriate number of seedlings are scraped from the long mat seedlings guided to the lower end of the seedling mounting table and transplanted to the field. In the transplanting machine having a transplanting nail to be transplanted, a plurality of seedling pressers for pressing the long mat seedling from the front side are provided on the seedling mounting table by shifting the position in the vertical direction, and a plurality of seedling pressers are positioned in the left-right direction. Are shifted from each other.
That is, as in the case where the right and left positions of the seedling presses provided at positions shifted in the vertical direction are matched, the same portion of the long mat seedling may be damaged by contacting the seedling presses many times, Inconvenient scraping can be avoided.

[0005]

Next, one embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a molded mat seedling to be placed on a seedling table 11 of a riding rice transplanter (transplanter) 2 and transplanted, and the molded mat seedling 1 is placed in a nursery box (not shown) of a predetermined size. The seed mat material 1a is laid, a predetermined amount of seeds are sown there, and the seedlings are raised for a predetermined period of time. The molded mat seedling 1 of the present invention has a length substantially equal to that of the seedling table 11 ( Up to a standard length (30 cm wide x 6 long), up to and including a little longer and shorter than the seedling mounting table length
It may be formed 1.5 times or 2 times as large as a molded mat seedling of 0 cm), and in the present embodiment, it is formed to be 150 cm long (about 2.5 times the standard). That is, when forming the molded mat seedling 1 to be long in order to reduce the number of times the seedlings are transported and the seams of the seedlings to be supplied, the length of the seedling mounting base 11 is set so as not to greatly exceed the length of the seedling mounting base 11. As a result, it is not necessary to provide a roll seedling feeding portion on the seedling mounting base 11 as in a roll seedling transplanting system in which the seedlings are mounted on the seedling mounting base in a rolled state. Become a seedling platform 11
It is possible to avoid an increase in the size and complexity of the structure.

As the nursery material 1a, a lightweight artificial mat obtained by molding crushed rice hulls with a general-purpose binding material is used. Therefore, the tensile strength and bending of the molded mat seedling 1 are determined according to the amount of the binding material mixed. The strength, shear strength and the like can be adjusted arbitrarily. In other words, while the molded mat seedling 1 is a long one, the required tensile strength can be secured, so that there is no inconvenience such as a gap at the seam due to deformation, and the appropriate bending strength and shear strength As a result, the molded mat seedling 1 can be handled in a roll state having excellent transportability, and good scraping can be performed.

Further, the molded mat seedling 1 is wound up in advance into a roll shape, and when the rolled molded mat seedling 1 is placed on the seedling mounting table 11 in a substantially planar manner and transplanted, the molded mat seedling 1 is removed. A roll seedling transplanting system in which the seedlings are reverse-wound so that the leaf stems fall down to the starting end side, so that the leaf stems fall down to the winding start side so that the leaf stems fall down comfortably. In comparison with the method described above, the winding operation of the seedling can be simplified, and the inconvenience of damaging the leaf stem and adversely affecting the growth after transplantation can be avoided.

And a seedling presser body 1 based on the engagement action.
9 is held in the evacuation position, while the evacuation lock release lever 2
When the swinging operation of the backing 6 is performed, the lock pin 26a is disengaged from the engaging groove 27a, and the returning swing of the seedling presser body 19 to the seedling holding posture is allowed.

By the way, the seedling pressers 20, 21, 22
Of the lower seedling presser 20 and the intermediate seedling presser 21,
It is formed by bending a wire rod.
Is configured using a roller member rotatably supported by a roller support shaft 28 facing in the left-right direction. In other words, the upper seedling presser 22 controls the floating while rolling on the molded mat seedling 1.
When feeding out from the upper end of the seedling mounting surface 11b, the protruding portion can be wound around the upper seedling presser 22 and held in a folded shape, and the folded portion can be used for rolling of the upper seedling presser 22. With this, it can be smoothly fed out. In addition, a plurality of grooves 22a are formed on the outer peripheral surface of the upper seedling presser 22 at predetermined intervals in the left-right direction so that pushing down of the leaf stem by the grooves 22a is avoided as much as possible. It has become.

Reference numeral 29 denotes a pair of right and left seedling holding brackets for supporting both ends of the roller support shaft 28. A plurality of reinforcing stays 30 are provided between the seedling holding brackets 29 at predetermined intervals in the vertical direction. In addition, the reinforcing stay 30 is provided with a plurality of elongated plates 31 whose upper ends are inserted into the grooves 22a of the upper seed presser 22 at predetermined intervals in the left-right direction. That is, the reinforcing stay 30 and the plate 31 function as a sagging regulating member that regulates the upper end side of the molded mat seedling 1 folded along the outer periphery of the upper seedling holder 22 from sagging toward the seedling mounting surface 11b. The plate 31 is also used as a mounting member for the intermediate seed presser 21.

6, pulleys 35b, 36 provided integrally with each other
b, a drive belt 37 suspended between the pulleys 35b and 36b, an elastic machine 38 for urging the first swing arm 33 toward the seedling mounting surface, and the like. Then, the rotating seedling holding discs 35 and 36 having biting teeth on the outer peripheral portion bite into the molded mat seedling 1 by the urging force of the ram 38 to regulate the floating and lateral displacement of the seedling. Rotating seedling holding disc 36
Is disposed so as to face the vertical feed belt 18 on the upper side of the seedling detection sensor S. That is, when the long molded mat seedling 1 is placed on the seedling mounting base 11 in a planar manner, the frictional resistance between the molded mat seedling 1 and the seedling mounting base 11 increases, and the vertical feed belt 18 Seedling feeding load increases,
There is a possibility that seedling feeding failure may occur. Especially, immediately after replenishing seedlings based on the detection of no seedling by the seedling detection sensor S, the contact area between the refilled molded mat seedling 1 and the vertical feed belt 18 is small. Although the feed belt 18 is likely to slip, the vertical feed belt 18 and the rotating seedling holding disc 36 are configured to feed the seedlings downward while sandwiching the molded mat seedling 1 from the front and the back on the upper side of the seedling detection sensor S. Even immediately after replenishing seedlings based on the detection of absence of seedlings by the sensor S, it is possible to successfully feed the replenished seedlings while preventing slippage. In addition, the molded mat seedling 1 of the present embodiment
Is a lightweight mat seedling using a lightweight artificial mat as described above, so that the seedling mounting surface 11b has a small sliding force due to its own weight, and the vertical feeding belt 18 easily slips due to floating. These inconveniences can be effectively prevented based on the seedling feeding action from the front and back by the vertical feed belt 18 and the rotating seedling holding disc 36.

The rotating seed presser disc 36 abuts against the vertical feed belt 18 via the molded mat seedling 1 in a resilient manner, so that the rotary seed press disc 36 rotates positively with the forced feed of the vertical feed belt 18. In other words, the rotational force of the rotating seedling holding disc 36 is transmitted via the drive belt 37 to the upper rotating seedling holding disc 35 disposed at a position not facing the vertical feed belt 18 so that the upper rotating seedling holding disc 36 is rotated. The disk 35 is forcibly rotated. In other words, the molded mat seedling 1 can be forcibly fed at a position where there is no vertical feed belt 18,
The seedling feeding load of the vertical feed belt 18 can be reduced to perform good seedling feeding, and the upper rotating seedling holding disc 35 is
Since it rotates positively while biting into the molded mat seedling 1, the lateral displacement of the molded mat seedling 1 can be regulated without causing seedling feeding resistance.
Since the upper rotating seedling holding disc 35 is forcibly rotated using the turning force of No. 6, the transmission structure can be simplified as compared with a case where power is separately secured.

On the other hand, the lower rotating seedling holding mechanism 32 includes a swinging arm 39 supported at the lower end of the seedling holding stay 23 via an arm support shaft 39a so as to be swingable back and forth.
A rotating seed presser disc 40 is rotatably supported at the tip end of the seedling via a support shaft 40a in a seedling feed direction, and a spring 41 for urging the swing arm 39 toward the seedling mounting surface. And, a rotating seedling holding disc 40 having a biting tooth on the outer peripheral portion.
Is controlled by the urging force of the ammunition device 41 so as to bite into the molded mat seedling 1 to prevent the seedling from rising or laterally displacing, but to face the vertical feed belt 18 on the lower side of the seedling detection sensor S. Are located. That is, when the seedling detection sensor S detects no seedling, the contact area between the remaining seedlings and the vertical feed belt 18 is small, so that the vertical feed belt 18 easily slips. Since the belt 18 and the rotating seedling holding disc 40 are configured to feed the remaining seedlings downward while sandwiching the remaining seedlings from the front and back, the remaining seedlings can be satisfactorily fed while preventing slippage. Reference numeral 42 denotes a forced evacuation bar integrally projecting from the swing arm 39. The forced evacuation bar 42 projects from the left and right evacuation lock plates 27 when the seedling presser body 19 is evicted. The lower rotating seed presser mechanism 32 is retracted more than the retracted amount at the lower end side of the seedling presser stay 23 in order to forcibly swing the swinging arm 39 rearward as it comes into contact with the stopper stay 43. Can do it, and
Since the lower end of the lower seedling presser 20 is engaged with the distal end of the swing arm 39, the lower seedling holder 20 also moves in conjunction with the forced swing of the swing arm 39. Can be largely evacuated.

The seedling pressers 20 and 21 and the rotating seedling press mechanisms 31 and 32 are each composed of a pair of left and right parts, and are disposed so as to be vertically displaced from the seedling mounting table 11. Therefore, it is possible to regulate the floating of the molded mat seedling 1 over substantially the entire area of the seedling feeding range. However, each of the seedling pressers 20 and 21 and the rotary seedling press mechanisms 31 and 32 can be used.
Are shifted from each other in the left-right direction, so that the seedling pressers 20 and 21 and the rotary seedling press mechanisms 31 and 32
As in the case where the left and right positions are matched, it is possible to avoid the inconvenience that the same place of the molded mat seedling 1 comes into contact with the seedling holding members 20 and 21 or the rotating seedling holding mechanisms 31 and 32 and is damaged many times. It has become. When the seedling holding body 19 is returned to the seedling holding position after placing the molded mat seedling 1 on the seedling mounting table 11, the seedling holding tools 20, 21 and the rotating seedling holding mechanisms 31, 32 disturb the leaf stem. However, each of the seedling pressers 20 and 21 and the rotating seedling pressing mechanism 31,
Since the seedling contact positions of the 32 seedlings are sequentially shifted in the left-right direction, the disorder of the leaf stem at the time of setting the seedling is not allowed, and the disorder of the leaf stem can be positively adjusted. As a result, poor scraping or damage to seedlings at the time of scraping due to disorder of the leaf stem can be prevented as much as possible.

Next, a method of mounting the molded mat seedling 1 on the seedling mounting table 11 will be described. However, as the molded mat seedling 1, a roll-shaped one that has been previously wound in a normal winding shape is prepared as described above, and a spare seedling to be replenished when the seedling runs out is formed at the upper end of the seedling mounting table 11. Spare seedling storage unit 44
Shall be housed in

At the beginning of the work, the seedling holding body 19
The seedling mounting surface 1 of each line is retracted from the seedling mounting surface 11b.
1b, one piece of the molded mat seedlings 1 is placed in a plane, and after that, the transplanting operation is started by returning the seedling holding body 19 to the seedling holding posture. When placed on a plane 11 in the present invention,
The roll-shaped molded mat seedling 1 is rolled from the upper end side of the seedling mounting table 11 and spreads flat on the seedling mounting surface 11b. That is, even if the leaf stem is wound up in a normal winding shape so that it falls down comfortably, the seedling mounting surface 11
When the leaf stem is deployed in b, the leaf stem falls down in the anti-seedling feeding direction, so that it is possible to avoid the inconvenience that the leaf stem interferes with the trajectory of the transplanted nail at the seedling scraping position.

When replenishing seedlings, the roll-shaped molded mat seedlings 1 (preliminary seedlings) are taken out of the spare seedling storage section 44 and the roll-shaped molded mat seedlings 1 are placed on the seedling mounting table as described above. Rolled from the upper side of 11 and unfolded into a flat shape, and this is added to the remaining seedlings. At this time, when the replenished molded mat seedling 1 is to be eaten from the upper end of the seedling mounting surface 11b, the feeding portion is set to It can be folded back along the outer periphery of the seedling presser 22, and the folded portion is sequentially and smoothly fed out with the rolling of the upper seedling presser 22. In other words, the long molded mat seedlings 1 can be connected to the seedlings when the seedlings are replenished without extending the seedling mounting base 11, so that the long molded mats 1 are placed flat on the seedling mounting base. However, it is possible to avoid the enlargement of the seedling mounting table 11.

In the structure constructed as described above, the seedling mounting table 11 for guiding the long molded mat seedling 1 downward along the seedling mounting surface 11b, and the molded mat seedling 1 guided by the seedling mounting table 11 A vertical feed belt 18 for forcibly feeding the seedlings on the back side of the
A transplanting nail 12 for scraping an appropriate number of seedlings from the molded mat seedling 1 guided to the lower end of the seedling mounting table 11 and transplanting the seedlings to a field is provided. 1
In order to provide the rotating seedling holding mechanism 31 for holding the vertical feed belt 18 from the front side, the vertical feed belt 18
The rotating seedling holding disc 36 that rotates in response to the forced seedling feeding is arranged, and the rotational force of the rotating seedling holding disc 36 is transmitted to the non-opposing position of the vertical feed belt 18 and is arranged at the position. Since the rotating seed presser disc 35 is forcibly rotated, the molded mat seedling 1 can be forcibly fed even at a position where the vertical feeding belt 18 is not opposed.
The seedling feeding load can be reduced and good seedling feeding can be performed. In addition, the rotating seed presser disc 35 disposed at the non-opposing position of the vertical feed belt 18 is forcibly rotated by using the rotational force of the rotary seed presser disc 36 disposed at the opposing position of the vertical feed belt 18. Therefore, simplification of the transmission structure can be achieved as compared with a case where power is separately secured.

A seed presser (a seed press 20, 21) for holding the long molded mat seedling 1 from the front side on the seedling mounting table 11.
In order to provide a plurality of rotating seedling press mechanisms 31 and 32 at different positions in the vertical direction, a plurality of seedling pressers are arranged so as to be shifted in the left-right direction. As in the case where the left and right positions are matched, it is possible to avoid the inconvenience that the same part of the molded mat seedling 1 comes into contact with the seedling presser many times and is damaged, or the leaf stem is disturbed and poor scraping occurs. it can.
