Description
本発明は苗床にて育苗した苗を本圃に移植する移植機に
関するもので、特に紙筒苗等の苗根部に土砂の付着した
苗を対象とするちのである。The present invention relates to a transplanter for transplanting seedlings grown in a nursery into a field, and is particularly intended for seedlings with dirt attached to their roots, such as paper tube seedlings.
紙筒等に播種育苗した苗はすべてが健苗となるわけでな
く、生育途上で枯れてしまう苗がかなりの割合で生じる
が、これを人手で取除いて移植機に供給することは非常
にわずられしい作業である。
そこで、この枯死した欠株苗の上部を自動的に取除いて
健苗のみを移植に供する、苗選別装置を組み込んだ移植
機が提案されている。
この苗選別装置とは、欠株苗の土部を自動的に取除き、
取り除いたことにより不揃になった苗列を検出器により
検出して苗列の速度を増減させ、個々の苗の間隔を詰め
て植付装置に供給するものである。
そして従来の苗選別装置では、不揃な苗を搬送し検出器
のある検出ベルトと、個々の苗の間隔を詰めて植付装置
に供給する集積ベルトを設け、検出器が苗を検出したと
きは検出ベルトと集積ベルトの速度を同一とし、検出器
が苗を検出しないときは検出ベルトの速度を集積ベルト
の速度より数倍速くしている。Not all seedlings sown and raised in paper tubes, etc. will turn out to be healthy seedlings, and a considerable percentage of seedlings will wither during growth, but it is extremely difficult to manually remove these seedlings and feed them to the transplanter. It is a tedious task. Therefore, a transplanting machine incorporating a seedling selection device has been proposed, which automatically removes the upper part of these dead and missing seedlings and allows only healthy seedlings to be transplanted. This seedling sorting device automatically removes the soil of missing seedlings,
A detector detects the rows of seedlings that have become irregular due to removal, increases or decreases the speed of the rows of seedlings, closes the distance between the individual seedlings, and supplies them to the planting device. Conventional seedling sorting equipment has a detection belt with a detector that transports irregular seedlings, and an accumulation belt that closes the gap between individual seedlings and supplies them to the planting device, and when the detector detects a seedling, The speed of the detection belt and the accumulation belt are the same, and when the detector does not detect a seedling, the speed of the detection belt is made several times faster than the speed of the accumulation belt.
検出ベルト上の不揃な苗列の個々の苗の間隔は、狭い場
合も広い場合も生じるが、欠株苗が少なく健苗が連続す
ると個々の苗の間隔が狭い場合が発生する。苗の間隔が
狭い場合にはその隙間を検出器で検出することができな
いため、検出ベルト上の苗列の速度が増加されずにその
まま集積ベルトに受け渡され、その部分の植付けられた
株間が広くなる。The spacing between the individual seedlings in the irregular seedling row on the detection belt may be narrow or wide, but if there are few missing seedlings and healthy seedlings are in succession, the spacing between the individual seedlings may be narrow. If the spacing between seedlings is narrow, the detector cannot detect the gap, so the speed of the row of seedlings on the detection belt is not increased and they are passed to the accumulating belt as is, and the distance between the planted plants in that area is reduced. It becomes wider.
本発明の移植機の苗選別供給装置は、植付装置に苗Ｐを

受け渡す苗選別供給装置において、検出ベルト３８の最
低速度を集積ベルト３９に対してやや速くしたものであ
る。The seedling selection and supply device for a transplanter according to the present invention is provided with an accumulating belt 39 that supplies seedlings P to the planting device, and a detection belt 38 that delivers the seedlings P to the accumulating belt 39. A detector 60 is provided, the speed of the accumulating belt 39 is linked to the planting device, and the speed of the detection belt 38 is linked to the detector 6.
In the seedling selection and supply device that increases or decreases the number of seedlings P upon detection of zero seedlings P and delivers them to the accumulating belt 39, the minimum speed of the detection belt 38 is made slightly faster than that of the accumulating belt 39.

5 to prevent drooping. As shown in FIG. 2, the planting section 8 has a pair of rubber disks 14 which are arranged in the center of a frame-shaped frame 16, and whose peripheral edges as a planting device can come into contact with each other. A rubber disk presser 22 having a large number of rollers rolling on the lower peripheral edge from the front is provided. An opener 12 is provided below the frame 16 in front of the rubber disk 14 to open a planting groove so that the bottom surface is below the lower edge of the rubber disk 14, and a suppressor and drive wheel are installed slightly behind the rubber disk 14 on both sides of the frame 16. A pair of suppression wheels 13 as
will be established. A chain case 17 is disposed above the front of the frame 16, and a number of shafts are provided protruding in the direction of the rubber disk 14, so that the seedlings P are conveyed by a number of belts, sorted, and delivered to the rubber disk 14. do. Above the chain case 17, a seedling supply conveyor 18 with its starting end slightly raised is stretched between the boot 19 of the shaft 20 and the boot (not shown) of the shaft 76, and a seedling presser sponge ring 24 is installed above the conveyance end on the shaft 25. The peripheral speed of each is approximately the same. A pulley 2 in which a long seedling feeding belt 26 facing the conveying end surface of the seedling feeding conveyor 18 is fitted downwardly at an angle of 3 degrees to the shaft 29.
8. A short seedling feeding belt 27 is stretched between the pulleys 28 and 28 fitted to the shafts 31 and 32 from below the conveyance end of the seedling supply conveyor 18, facing the seedling feeding belt 26. However, the seedling feeding belt 26 and the seedling feeding belt 27 rotate at the same circumferential speed so that their contact surfaces face downward, and their circumferential speed is made slightly faster than that of the seedling feeding conveyor 18. A large number of winglet-like protrusions are planted on the surfaces of the seedling feeding belt 26 and the seedling feeding belt 27, and the pitch and height are approximately half the diameter of the seedling P, and a row of winglets is planted in the center of the belt. Not set. A belt receiver 3 that rubs against the inner surface of the seedling feeding belt 26 facing the junction between the seedling supply conveyor 18 and the seedling feeding belt 27
3 to prevent the seedling feeding belt 26 from bending inward. A string-shaped belt 36.37 is stretched below the conveying end of the pair of seedling feeding belts 26.27 by a pulley 4o supported by a shaft 41.4243, and the seedlings are transported in the opposite direction to the conveying direction of the seedling supply conveyor 18. and the peripheral speed is the seedling supply conveyor 1.
Make it a little faster than 8. A seedling guide 34 is provided between the conveyance end of the seedling feed belt 26 and the conveyance start end of the belts 36 and 37, and is installed diagonally so that the lower part of the seedling guide surface faces the seedling conveyance direction, and the pair of seedling feed belts 26.
The seedlings P discharged from 27 are made to slightly contact the seedling guide surface and be slightly urged in the conveying direction of the belt 36°37. A belt receiver 35 is provided below the conveying end of the pair of seedling feeding belts 26, 27 to sandwich the conveying surface layer of the belts 36, 37 to prevent the belts 36, 37 from bending downward due to falling of the seedlings P. let The belt 36 near the rubber disk 14, that is, the leaf blade PC of the seedling P
A leaf receiving belt 74 with a width between the leaf blades PC and the path width is arranged in parallel with the leaf blade PC at the same conveyance speed as the belts 36 and 37 in the direction, and the leaf blade PC of the seedling P is received and conveyed. The leaf blade P of the seedling P from the belt 36 that receives the leaf blade PC side of the seedling P.
The belt 37 that receives the opposite side of the seedling C is made longer in the conveying direction, so that when the seedling P reaches the end of conveyance of the belt 36, the belt 37 receives only the opposite side of the leaf blade PC of the seedling P, and this belt 36 is removed. A leaf pressing belt 73 is arranged corresponding to the leaf holding belt 73, and the leaf holding belt 73 is arranged so as to be in contact with the upper surface of the leaf receiving belt 74 with the same width so as to pinch and transfer the leaf blade PC. The leaf receiving belt 74 and the leaf pressing belt 73 are connected to the shaft 71.72.
, 69 and 70, and are stretched between the pulleys 75 which are supported by the pulleys 75 and 75, and are driven at the same circumferential speed. Axes 71, 72, 69.
70 is locked to a receiving plate 67, and the receiving plate 67 is locked to the chain case 17. The string-like detection belt 38 is connected to the belt 37 and attached to the shaft 43.
．． The belt 36
．． 37 and the detection belt 38 are connected by a chain wheel so that the peripheral speeds of the belt 37 and the detection belt 38 are always the same. A string-like accumulation belt 39 connected to the detection belt 38 is stretched between pulleys 40 supported by shafts 44 and 45. The pulley 40 is fixed on the shaft 43, loosely fitted on the shaft 44, and fixed on the shaft 45. Then, the rotation of the shaft 45 causes the accumulation belt 39 to rotate. Also, in the chain case 17, the chain wheel on the freewheel provided on the shaft 45 and the chain wheel on the shaft 43 are connected by a chain,
The chain wheel on the shaft 45 and the chain wheel on the shaft 44 are connected by a chain, and the chain wheel on the shaft 4
The chain wheel on 4 and the chain wheel on the electromagnetic clutch provided on the shaft 43 are connected by a chain. In this way, when power is transmitted from the shaft 45 to the shaft 43, the speed is increased when the power is transmitted through the electric m-clutch than when it is transmitted through the freewheel.
The rotation of the shaft 43 causes the detection belt 38 and the belt 37 to rotate, and the rotation of the shaft 43 causes the rotation of the belt 3 from the seedling supply conveyor 18.
6 to rotate at a predetermined speed ratio. A detector 60 is disposed above the conveyance end of the detection belt 38, and the electromagnetic clutch is disengaged when the detector 6Q detects the seedling P or the gap therebetween, and is connected when the seedling P is not detected, and the freewheel is activated when the seedling P is detected. When the seedling P is not detected, the power is transmitted to f2 via the electromagnetic clutch. Compared to the accumulation belt 39, the seedling supply conveyor 18 is a little slower and the detection belt 38 is a little faster at the time of detection, and the seedling supply conveyor 18 is faster at the time of non-detection, and the detection belt 38 is 2~
Make it 4 times faster. A seedling presser sponge ring 46 is placed above the conveyance end of the accumulating belt 39.
is supported on a shaft 47, and the same circumferential speed is set as -. A seedling feeding belt 4 that is long downward facing the conveying end surface of the accumulating belt 39
8 was stretched between the booths 28 fitted on the shaft 50.51, and a short seedling feeding belt 49 was fitted on the shaft 52.53, facing the seedling feeding belt 48 from below the conveyance end of the accumulating belt 39. The seedling feeding belt 48 and the seedling feeding belt 49 are stretched between the pulleys 28 and rotate at the same circumferential speed so that their contact surfaces face downward. The conveying ends of the pair of seedling feeding belts 48 and 49 are made to face the front seedling receiving part of the rubber disk 14. A fixing piece 55 for correcting the posture of the seedlings P is disposed on the long seedling feeding belt 48 side of the triangular space formed by the conveying end of the accumulating belt 39 and the conveying start end of the short seedling feeding belt 49. The above accumulation belt 39, the seedling presser sponge ring 46, the pair of seedling feeding belts 48, 49, and the rubber disc 14 are the pressing ring 13.
The power is transmitted by chain wheels and gears, and it is driven with the suppression wheel at a constant circumferential speed. Next, the operation will be explained. The operator inverts the seedlings P from the seedling table 7 onto the seedling supply conveyor 18 and sequentially arranges them. At this time, the seedlings P may be glued together or may be separated from each other. PA is a healthy seedling with leaf blade PC, while PB is a deficient seedling and has no leaf blade PC, so it must be removed. As the tractor advances, the pressing wheel 13 rotates, and the seedling supply conveyor 18 accompanies it to transport the seedlings P arranged in a row. Each time the seedlings P that have reached the conveyance end of the seedling supply conveyor 18 pass through the seedling presser sponge ring 24, they are separated by the seedling feeding belt 26, which is longer than the seedlings P that have not yet passed through the seedling presser sponge ring 24, and are separated at appropriate intervals. A pair of seedling feeding belts 26.2
7 and transported downward. At this time, the belt receiver 33 prevents the seedling feeding belt 26 from bending inward even if it is pushed by the seedling P.
It is transferred in an orderly manner without any play. Seedling P that has reached the end of conveyance of a pair of seedling feeding belts 26 and 27
are delivered to the belts 36 and 37, and the leaf blades PC are delivered onto the leaf receiving belt 74, but at this time, the seedlings P are slightly biased in the transport direction by the seedling guide 34, and the seedlings P are pushed in the transport direction of the seedling supply conveyor 18. Since the seedlings P that follow are transferred in the opposite direction,
does not interfere with Further, although the seedling P descends onto the belts 36 and 37, since the belt receiver 35 is sandwiched against the back surface of the belt, it does not bend, so the seedling P does not jump and disturb its posture. When the seedling P reaches the end of conveyance of the belt 36, the healthy seedling PA with a leaf blade PC is held by the leaf receiving belt 74 and the leaf pressing belt 73, and then reaches the missing part of the belt 36 and is transferred to the belt 37. However, the missing seedling PB without leaf blade PC is supported only by the belt 37 and immediately falls from the missing part of the belt 36, so the detection belt Only healthy seedlings PA with leaf blade PC will be transferred onto 38. Subsequently, when the row of irregular seedlings P reaches the end of the conveyance of the detection belt 38, the electromagnetic clutch is turned on and off depending on whether or not the detector 60 detects the seedlings P, and the conveyance speed of the detection belt 38 is increased or decreased, and the individual seedlings are separated. They are transferred to the accumulation belt 39 with the interval P narrowed. Furthermore, when the number of missing seedlings PB is small and healthy seedlings PA are consecutive and the detection belt 38 is slow, the gap between the seedlings that cannot be detected by the detector is also closed by the speed difference between the detection belt 38 and the accumulating belt 39. The seedlings P transferred to the accumulating belt 39 are transferred while being held between a pair of seedling feeding belts 48 and 49, and are received by the rubber disk 14.The rubber disk 14 is transferred while holding the upper part of the seedling P. Plant in the main field.

Since the seedlings P are packed together at a speed difference of 9, arranged at appropriate intervals on the accumulating belt 39, and supplied to the device, there is no irregularity between the planted seedlings P. In this way, the seedlings P are transported in a continuous and orderly manner, and the missing plants are removed before being transplanted, resulting in a significant reduction in labor and reliable planting.
