Description

[Detailed description of the invention] Industrial application field The present invention relates to a seedling feeding device for a seedling transplanting machine, and more specifically, it is capable of easily feeding seedlings to a planter supported by a rotating shaft that rotates in conjunction with the movement of the machine. The present invention relates to a seedling feeding device that can prevent the occurrence of missing plants, etc. in this way.

2. Description of the Related Art In general, there is a known seedling transplanting machine for sweet potato, etc., which rotates a planter in conjunction with the movement of the machine, and transplants seedlings supplied at a raised position of the planter into a field at a lowered position of the planter. However, in conventional seedling transplanters, the planter supported by the rotating shaft rotates along an arc-shaped cam surface, so the planter that rises from the driver's seat immediately descends, making it difficult to maintain the raised position. Seedlings must be supplied during the short time it passes. For this reason, it is difficult to time the feeding of seedlings to the planter, and there is a drawback that seedlings may be mistakenly fed, resulting in missing plants.

Problems to be solved by the present invention The present invention was devised to solve these problems in view of the actual situation as described above, and its purpose is to Even if the planter is rotated by being supported by It is an object of the present invention to provide a seedling supply device for a seedling transplanter that can prevent the occurrence of plant shortages due to failure to supply seedlings.

Means for Solving the Problems In order to solve the above problems, the technical means adopted by the present invention is to rotate a planter supported on a rotating shaft linked to the traveling of the aircraft along a rotating guide surface, In the seedling transplanter, the seedlings supplied at the raised position of the planter are implanted in the field at the lowered position of the planter, in which a bulge is formed at the raised position of the planter on the rotation guide surface, and the raised planter is placed in the bulged part. The planter is characterized by forming a horizontal guide surface that guides the planter substantially horizontally in the rotational direction while holding the planter in the raised position, thereby forming a wide range of seedling supply positions where seedlings can be supplied to the planter.

Effect of the invention Therefore, according to the invention, when transplanting sweet potato seedlings, etc., a planter that is supported by a rotating shaft that is linked to the traveling of the machine and rotates along a rotating guide surface,
If the seedlings are fed at an elevated position along the bulge of the rotating guide surface, the seedlings will be planted in the field when the planter descends, so the seedlings will be sequentially fed to the elevated planter to produce sweet potato seedlings, etc. Can perform porting work. The raised planter is then guided approximately horizontally in the rotational direction along the horizontal guide surface formed in the bulge, so that a wide range of seedling supply positions can be created by the planter held in the raised position. It is possible to supply seedlings in a timely manner, prevent erroneously failing to supply seedlings, and smoothly perform transplantation work of sweet potato seedlings and the like.

Embodiment An embodiment of the present invention will be described in detail based on the attached drawing of a sweet potato seedling transplanter. 1 has 2 front wheels and 3 rear wheels,
This is a fuselage frame with an engine 4 mounted at the rear thereof, and a rotating shaft 5 is provided in the width direction of the fuselage frame 1, located between the front wheels 2 and the rear wheels 3. The rotating shaft 5 is the engine 4
It is connected via a pulley, chain, etc. to a transmission mechanism that transmits power to the rear wheels 3, and rotates in the same direction as the rear wheels 3 in conjunction with the travel of the aircraft.

Reference numeral 6 denotes a plurality of planter arms projecting radially from the rotating shaft 5, the planter arms 6
has connecting arms 7, 7 pivotally attached to the distal end thereof.
Planters 9, 9, . . . are supported through parallel links 8, respectively. Above planter 9
A spring 10 stretched between the planter arm 6 and the cam body 11, which is arranged concentrically with the rotation shaft 5, is biased to press against the rotation guide surface 12 on the outer periphery of the cam body 11 via a roller 13. As the rotation shaft 5 rotates, the planter 9 rotates along the rotation guide surface 12. The cam body 11 also has a straight portion 1 that guides the rotating planter 9 so as to approach the rotating shaft 5 in the process of ascending from the vicinity of the lowest position.
1a is formed, and the driver sitting in the driver's seat 14 holds the seedling a in the raised position on the seedling holding surface 9a formed on the outer periphery of the planter 9 that has been raised from the front side, and the planter 9 is in the lowered position. It is designed to be planted in the shape of a ship's bottom when passing through the field.

The rotation guide surface 12 of the cam body 11 has a second
As shown in the figure, a bulging part 15 is formed to raise the planter 9 to the raised position, and the bulging part 15 further has a bulging part 15 that is substantially horizontal in the rotational direction while holding the raised planter 9 in the raised position. A horizontal guide surface 15a is formed to guide the planter, and a seedling supply position A is formed over a wide area where a driver sitting in the driver's seat 14 can supply seedlings to the planter 9. Reference numeral 16 denotes a root side clamping part provided on the planter 9, and 17 denotes a leaf tip side clamping part.

In the above configuration, when transplanting sweet potato seedlings, if the seedling transplanter is run along the ridges,
A planter 9 attached to a planter arm 6 rotates in the direction of the arrow x in conjunction with the traveling of the machine. Next, when the driver sitting in the driver's seat 14 sequentially holds the sweet potato seedlings a on the seedling holding surface 9a of the planter 9 that has been raised from the front side, the planter 9 descends and places the sweet potato seedlings a in the shape of a boat in the field. Can be implanted. When feeding the sweet potato seedlings a, the planter 9, which has risen along the bulge 15 of the rotation guide surface 12, is guided approximately horizontally in the rotational direction along the horizontal guide surface 15a, so that Since the planter 9 passes through the rotation trajectory shown by the solid line A in FIG. 4, the time period during which the planter 9 is held at the elevated position where it can supply the sweet potato seedlings a becomes longer. Therefore, compared to the seedling supply position B of the conventional system in which the planter is guided by the arc-shaped cam surface A and the rotation locus is as shown by the chain line C, sweet potato seedlings A can be distributed from a wide range of seedling supply positions A.
Since it can be supplied in a timely manner, there is no chance of accidentally failing to supply it, and the transplanting work can be carried out smoothly.

Effects of the invention In short, the present invention rotates a planter supported on a rotating shaft linked to the traveling of the machine along a rotating guide surface, and plants seedlings supplied at the raised position of the planter in the field at the lowered position of the planter. In the seedling transplanter, the rotating guide surface has a bulge formed at the planter raising position, and a horizontal bulge that guides the raised planter substantially horizontally in the rotational direction while holding the raised planter in the raised position. Since the guide surface is formed and the seedling supply position where seedlings can be supplied to the planter is formed over a wide range, seedlings can be supplied from the raised position to the planter that rotates in conjunction with the movement of the machine.
The planter that has risen along the bulge of the rotating guide surface does not immediately descend, but is guided approximately horizontally in the rotational direction along the horizontal guide surface formed on the bulge, so that the planter can rise enough to supply seedlings. The time that the seedlings are held in the same position is longer, and the seedlings can be supplied in a timely manner from the seedling supply positions that have been formed over a wide area, and there is no chance of accidentally failing to supply seedlings, which reduces the occurrence of plant shortages, etc. This has extremely useful practical effects, such as being able to prevent this from occurring and allowing for smooth seedling transplantation.
