Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seeding roll and a seeding device of a seeder for raising rice seedlings.

[0002]

[Prior art]

 Conventionally, the relational position between the seeding roll and the surplus seed padding sweeping brush of this kind of seedling raising seeding machine has been mainly on the center line of the seeding roll or on the front side in the rotation advancing direction. In the part in front of the direction of rotation, low speed, that is, a small amount of thin sowing was the mainstream, and there was a problem with standard or slightly overseeding, and it was not used.

[0003]

[Problems to be solved by the device]

 Recently, in order to increase the yield of high-quality rice due to intensifying competition among production areas, first of all, it is required to have a high seeding accuracy of a sowing machine called a healthy seedling, and at the same time, a collaborative work for labor saving. There is also a tendency to produce a large amount of seedlings, and there is a demand for a high-speed and high-performance seeder, and how to respond to it is a major issue.

[0004]

[Means for Solving the Problems]

 As described above, the present invention makes sure that the seed pad can be surely put into the seed pad feeding recess of the seed roll, and that the seed pad once put into the roll can be rolled in order to make it a high-speed and high-performance seeder. This is to ensure that the seedling box surface filled with the bed soil that is guided by the cover is seeded. Therefore, in the present invention, in order to effectively use the horizontal portion of the upper surface of the sowing roll, the surplus seed pad sweeping brush is installed at a position advanced in the rotation direction of the seed roll to increase the time for the seed pad to enter the recess of the seed pad, First, make sure that more seeds are in the rice. Next, by deciding how to remove the harmful effect caused by it, by installing a rotating roll in front of the sweeping brush, in order to prevent unnecessary seeds from accumulating and disturbing It is possible to stabilize the supply of seed paddy into the feeding recess and to arrange the feeding recess of the seeding roll in a puddle so that the seeding device can handle from ultra-thin sowing to thick sowing.

[Action]

 A horizontal frame with a built-in transport mechanism, a seed hopper at an appropriate position above the horizontal frame, a seeding roll having a recess for seed seed feeding at the bottom of the hopper, and a seed pad in the recess of the seeding roll. The basic structure is a roll cover that holds and guides the seed soil to the soil surface of the seedling box securely.However, with this structure alone, it is not sufficient to adjust the seeding amount in general and the rotation speed of the seeding roll is particularly high. In the case of large-scale seeding, the range that could meet the demand was very small.Therefore, in the present invention, when considering the flow of seed paddy, the seed paddles along the bottom of the hopper and hits the descending seeding roll. The sowing roll is rotating. The direction of rotation is upward at the point of contact with the bottom of the hopper, and the seed paddy is pulled upward by the rotational force, and the seed cover is placed in the feeding recess of the seeding roll. Then, they are guided by a roll cover and sown. In order to put seed paddy into the feeding recess of the sowing roll, it is first necessary to increase the time during which the seed pad is in contact with the seed roll as much as possible, and therefore, the side in contact with the hopper should be wide. Then, the tangent line of the sowing roll becomes nearly vertical, and the pushing action is rather stronger. On the other hand, if it is attempted to make it wider than the apex of the seeding roll on the opposite side, it is difficult for the sweeping brush to be swept out and it becomes too thick to accumulate, making it difficult to achieve a stable state. Therefore, in the present invention, at the start point of seed rice supply from the hopper to the sowing roll, the contact point with the sowing roll should be widened up to the vicinity of the vertical in order to make it as wide as possible, and the seed rice should be prevented from being entangled with each other. A feeding and stirring roll is used to make it easier for seed rice to enter the feeding recesses. The seed roll will continue to rotate in the state where the seed pad is fed to the feeding recess, and the seed pad is fed to the feeding recess. On the other hand, if you make it wider at the upper part beyond the apex to make it wider, it will be difficult to return extra seed paddy, and it will be too much to accumulate and it will be difficult for the seed padds to get entangled and enter the recess for feeding. Rather, the removal of harmful effects became a problem. In order to make it easy for the seed rice to enter the recesses and to make the most stable entry, the near-horizontal part of the top surface of the seeding roll is effectively used to ensure that the seed rice that is rotatably conveyed is stable to some extent. The position where the seed roll is fed to the feeding recess is ensured at the most stable position on the center line of. Simultaneously, in order to remove seed rice that is piled up more than a certain amount and entangled with each other, which hinders the seed rice from entering the feeding recess, a radial stable feeding roll with a cross-sectional shape is used to feed the seed roll to the feeding recess. In addition to ensuring a stable supply posture, excess seed paddy was returned to the supply side to make the supply of seeding rolls into the feeding recesses more stable. In the stable state, when it is further advanced from the center line, the excess seed pad sweeping brush is used to remove the extra seed pad other than the seed pad that has finally entered the feed pad of the seeding roll. High-performance and stable seeding can be achieved by removing all but the seed paddy and advancing to the roll guide while it is completely supplied to the feeding recess of the seeding roll. Among them, the problem is the relative position of each roll and brush. When the seeding roll, the feeding stirring roll, and the feeding stabilizing roll are too close to each other, contrary to the purpose, they do not promote the feeding but scrape out.On the contrary, when they are far from each other, there is no effect and it is difficult to select the position and the seed pad is short. Diameter of 1. Something starts to be scraped out when the distance is closer than 8 times, and the effect disappears when the distance is more than about 2.5 times. By adjusting in that range, it is possible to more stably handle up to twice as many rotations as the conventional seeding device, and it is possible to arrange a puddle containing one grain in the feeding recess, which was not possible with the conventional method. became . Conventionally, the number of feeding recesses containing 2 grains was set to be the same as the number of seeding rolls in the axial direction, and the width of 2 grains was set to 1 grain, and the widened part was used for scraping to prevent seed paddy from clogging. By digging the grooves and arranging the feeding recesses in a puddle arrangement, the seeding amount will be the same as the conventional seeding amount for two rows. Therefore, for ultra-thin sowing, the number of seeds in one row is halved, and it is possible to meet the demand up to half of the conventional seeding amount, and also for thick sowing. By setting the relationship between the seeding roll and each roll as described above, it is possible to sufficiently cope with the seeding amount higher than the conventional amount.

【Example】

 A horizontal frame A in which the transport mechanism B is incorporated, a seed hopper 1 provided at an appropriate position above the horizontal frame A, and a seeding roll 4 having a seed pad feeding recess 41 at the bottom of the hopper 1. A seeding machine basically configured with a roll cover 5 that holds the seed paddy that has entered the feeding recess 41 of the seeding roll until it is surely seeded on the soil surface 61 of the seedling box 6 that has been reliably transported. Is. In the seeder having such a basic structure, the relation between the seed hopper and the seeding roll will be described. The seed pad 7 flowing along the bottom surface 11 of the seed padding hopper 1 is a seeding roll at the contact point between the seeding roll 4 and the hopper bottom surface 11. The seed roll 7 is lifted upward by the rotation of the seeding roll 4, and at the same time, the seed pad 7 is put into the feeding recess 41 and is rotatably conveyed. The seed pad 7 is fed by the feeding stirring roll 31 to feed more seed pad. After entering the concave portion 41, the rotation conveyance is advanced, and the seed roller 4 is conveyed to the vicinity of the center of the upper surface. However, the state of the seed paddy 7 in the feeding recess 41 conveyed to this point is that the seed paddy 7 supplied is in an unstable state because the position of the supply stirring roll 31 is considerably lower. , The seed pad 7 in the horizontal portion near the center of the upper surface of the sowing roll 4 can be easily inserted into the feeding recess 41, and the feed stabilizing roll 32 is adopted at a position where the seed pad 7 can be fed into the feeding recess 41. At the same time as surely storing, the entangled extra seed rice 7 which overlaps and obstructs the accommodation of the seed pad 7 in the feeding recess 41 is returned to the upper portion of the feed stirring roll 31 which is the original feeding position and fed. Only the seed paddy 7 necessary for stable supply to the concave portion 41 is left and is rotatably conveyed. Since the position of the supply stabilizing roll 32 is for the purpose of surely storing the seed pad 7 that has not yet been stored in the feeding recess 41 into the feeding recess 41, the distance from the seeding roll 4 is important and too close. The seeds 7 that had just been settled out would result in bad results, and if they were too far apart, it would give bad results to the next work as if there were no seeds. 1.8 times to 2.5 times is appropriate, and by mounting the supply stabilizing roll 32 in the position of the range, the seed pad 7 is stably stored in the feeding recess 41 of the seeding roll 4 in the next step. A sweeping brush 33 is provided so as to remove excess seed pad 7 other than the seed pad 7 that has finally been stored in the feeding recess 41 of the seed roll so as to be taken over by a certain roll cover 5. As a result, stable performance can be achieved up to twice as fast as the conventional sowing roll device, and the feeding recess 41 of the sowing roll 4 containing one grain, which was not possible in the past, was provided. It was possible to provide a seeding device that can be arranged in a plover and can handle ultra-thin sowing to conventional thick sowing.

[Effect of device]

 As described above in the section of action, a horizontal frame with a built-in transport mechanism, a seed pad hopper provided at an appropriate position above the horizontal frame, and a seeding roll provided with a seed pad feeding recess at the bottom of the hopper. The basic structure is a roll cover that securely holds and guides the seed paddy that has entered the concave part of the sowing roll until it is sown on the soil surface of the seedling box.However, this structure alone does not support general adjustment of the seeding amount. In the case of large-scale sowing in which the rotation of the sowing roll is high, it was not possible to meet the demand.Therefore, in the present invention, at the starting point of the supply of seed paddy from the hopper to the sowing roll, the sowing roll was The use of a feeding and stirring roll for facilitating the entry of seed paddy into the feeding recesses promotes the feeding of seed padding to the feeding recesses, and most of the seed paddles are fed to the feeding padding recesses. It has been in a state, has become and those that contain in a state of stable seeds entering the feeding recess, the state and are mixed those of an unstable state that only contains about half. This is further rotated and conveyed, and is rotatably conveyed to the vicinity of the center line of the seeding roll, and the horizontal part on the center line that is the most stable and easy to enter is effectively used to ensure the stable supply to the feeding recess. Things are needed. Therefore, in order to further promote and ensure a stable supply to the seeding rolls, the supply stabilizing rolls were used to prompt the supply of the seeding rolls to the feeding recesses again, and the seed paddy that entered the feeding recesses became more stable. State and returning the seeds that are piled up and entangled more than necessary to the supply side to make the supply to the feeding recess of the seeding roll more stable, and when further advancing from the center line in that stable state, In order to finally remove only the surplus paddy rice other than the seed pad that has entered the feeding recess of the sowing roll, use the surplus seed pad sweeping brush to remove the seed pad except the seed pad that has entered the feeding recess of the seeding roll. By fully advancing to the roll guide while being completely supplied to the feeding recess of the sowing roll, high-performance and stable sowing can be performed. In this way, the most stable and reliable seed paddy around the center line of the seeding roll can be supplied and stored in the feeding recess of the seeding roll, thereby achieving a higher effect than the conventional seeding device. It has become possible to achieve the same effect at low speed, that is, thinning, and especially at high speed, and it is possible to obtain a more than double effect. By doing so, it is possible to perform from very thin sowing to thick sowing.
