Description

[Detailed description of the invention] This invention relates to a planting claw with an L-shaped tip that scrapes, divides and clamps seedlings for planting from a group of seedlings.

In general, planting claws are used to scrape, divide, and hold seedlings for unit planting in sequence from a pine-shaped cluster of seedlings, and then plant them on the rice field. Some are known to be L-shaped. These seed planting claws have inner surfaces facing each other that are tapered toward the outer surface, which becomes flat toward the tip. The contact surface of the seedling is clamped to improve seedling retention performance, but if the clustered seedlings have poor rooting or have dried out, the tapered inner surface may be used for planting. It has the disadvantage that the seedlings collapse, and conversely, the seedling retention performance decreases, resulting in dropped or floating seedlings, resulting in missing plants.

On the other hand, as shown in Figure 7, the tips of the planting claws protruded into the seedbed surface of the clustered seedlings in a forward-slanted manner in the direction of division, so the division surface of the remaining clustered seedlings was pulled in the direction of division. This had the disadvantage that the end surface of the seedbed was disturbed and the normal action of scraping and dividing the planted seedlings could not be performed, resulting in a decline in seedling planting performance.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation.The present invention has been devised in order to eliminate these drawbacks. The opposite L-shaped inner surfaces of the tips are configured to be substantially perpendicular to the seedbed surface when dividing the planted seedlings, and The side edge and the lower edge are each formed with a forwardly sloping part, and the L-shaped outer surface is tapered toward the inner surface toward the tip, so that the tip is sharp. By this method, even if there are grouped seedlings in poor conditions such as poorly rooted or dry seedlings, they can be reliably separated and planted on the rice field to prevent the occurrence of scattered seedlings or floating seedlings. To provide a planting claw that can prevent the dividing surface of a seedling from being disturbed when the planted seedling is divided.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 is a planting rod installed in a rice transplanter, and the planting rod 1 is configured to circulate in the vertical direction. It's summery. A planting claw 2, which will be described later, is attached and fixed to the tip of the planting rod 1 so as to face downward.
Reference numeral 3 is a fork for pushing out the planted seedlings, which is provided on the rear side of the planting claw 2. The fork 3 moves upward when dividing the seedlings and comes into contact with the upper part of the planted seedlings S. It descends in conjunction with the downward movement of the planting rod 1 to the bottom dead center, and pushes out the planted seedlings S held by the tips of the planting claws 2 to be planted on the rice field.

The base end of the planting claw 2 is formed into a gate-shaped cross section, and a support pin 4 is interposed between the left and right side walls 2a. Furthermore, a through hole 2c is formed in the mounting portion 2b protruding from both side walls to be fixed to the planting rod 1 via a tightening bolt 5. On the other hand, the tip portion 6 of the planting claw 2 is divided into two parts by notching the beam portion 2d of the planting claw 2 in the longitudinal direction. Therefore, the tip portion 6 has left and right tip portions formed of an L-shaped cross-sectional inner surface 6a and an outer surface 6b, which are formed to face each other by the portions corresponding to the left and right side walls 2a and the portions corresponding to the divided beam portion 2d. has been done. The opposing inner surfaces 6a of the tip portions 6 are each shaped like a flat plate, and are designed to protrude substantially perpendicularly to the seedbed surface of the group seedlings P when the planted seedlings S are scraped and divided.
In addition, the planting claw tip portion 6 has sloped portions 6c, 6c facing forward, respectively, formed on the side edge of the portion corresponding to the beam portion 2d and the lower end edge of the portion corresponding to both side walls 2a, and furthermore, the planting claw L-shaped outer surface 6b of tip portion 6
A tapered portion 7 is formed such that both the portions corresponding to the left and right side walls 2a and the portions corresponding to the beam portion 2d are inclined toward the inner surface 6a toward the distal end side. For this reason, the planting nail tip 6 has a sharp wedge shape with the tip as the apex.

In addition, in the figure, 8 is a seedling mounting stand, and 9 is a seedling receiving plate.

Next, the operation of the present invention constructed as described above will be explained. The planting claw 2 scrapes and divides the planted seedlings S from the group of seedlings P placed on the seedling table 8 by the vertical circular movement of the planting rod 1, and plants them on the rice field. , since the tips 6 of the planting claws 2 have a sharp wedge shape when scraping and dividing the planted seedlings S,
It is possible to easily enter the group of seedlings P placed on the seedling table 8 and accurately divide the planted seedlings. At this time, the inner surface 6a of the tip 6 protrudes at a substantially right angle to the seedbed surface of the group seedlings P, but the L-shaped outer surface 6b of the tip 6 has a tapered portion 7 inclined with respect to the seedbed surface of the group seedlings P. It will be entered in this state. For this reason, the dividing surface of the remaining grouped seedlings P is compressed by the tapered part 7 on the front side and either one of the left and right sides with respect to the direction in which the grouped seedlings P are pulled out, so that the upper surface of the seedling bed is compressed. When the planted seedlings S are scraped and divided, the dividing surface on the side of the grouped seedlings P that remains is not pulled in the dividing direction and disturbed.

On the other hand, the planted seedlings S are scraped and divided from the group seedlings P.
is held between the left and right tips 6 of the planting claws 2, but when scraping and dividing, the L-shaped inner surface 6a of the tips 6 protrudes at a substantially right angle to the seedbed surface to scrape and divide. Therefore, the dividing surface of the planted seedling S is not subjected to any pressing action from the inner surface 6a of the planting claw 2. Therefore, even if the group seedlings P are under poor conditions such as poorly rooted or dry seedlings, the planted seedlings S
This is due to the fact that the front surface and either one of the left and right sides are pressed together by the outer surface 6b of the planting claw 2 with respect to the feeding direction of the group seedlings P when the previously planted seedlings S are scraped and divided. The seedlings are held in a predetermined shape without collapsing. For this reason, when using grouped seedlings P under poor conditions, such as the conventional one in which a taper is provided on the inner surface 6a side of the planting claw 2 and the dividing surface is compacted when scraping and dividing, the occurrence of dropped seedlings or floating seedlings. It is possible to prevent this and obtain well-ordered planting rows with no missing plants. In addition, the planted seedling S that is split and clamped has a cross section L
Since it is held in a wide clamping area by the letter-shaped planting nails 2, it will not fall off from the planting nails 2.

In the above embodiment, the planting claw 2 having a bifurcated tip was described, but the invention is not limited to this, and a pair of left and right planting claws each having an L-shaped cross section may be provided. .

In summary, the present invention attaches to a planting rod that circulates in the vertical direction a planting claw having an L-shaped cross-sectional outer surface and an inner surface facing each other; The L-shaped inner surface is configured to be substantially perpendicular to the seedbed surface at the time of dividing the planted seedlings, and a forward slope is formed on the side edge and lower edge of the tip, respectively, In addition, since the L-shaped outer surface is tapered toward the inner surface toward the tip, and the tip is sharp, the tip will not be sharp when scraping and dividing the planted seedlings. The mature planting claws can easily penetrate into grouped seedlings and accurately divide and hold the planted seedlings. The dividing plane of the remaining group seedlings is configured in a tapered shape L.
Both the front and side surfaces of the collective seedlings in the pulling direction are pressed and compacted by the letter-shaped outer surface, and it is possible to prevent the occurrence of seedbed disturbance caused by pulling in the dividing direction, and moreover, Coupled with the fact that the seedlings are held by the L-shaped inner surfaces that are substantially perpendicular to each other and face each other, even grouped seedlings in poor conditions, such as poorly rooted or dry seedlings, can be held on the holding surface. This prevents deformation of the seedlings, eliminates seedling collapse, prevents the occurrence of dropped seedlings and floating seedlings, and provides well-ordered planting rows without missing plants.
