[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a transplanting machine for transplanting seedlings such as sweet potato, and more particularly to a device for adhering soil to the transplanted seedlings.

[0002]

2. Description of the Related Art A conventional device for bringing soil to transplanted seedlings is
It was a device that moved up and down to knock down the ridges and bring in the soil.

[0003]

[Problems to be Solved by the Invention]
It only hits the ridges up and down, not the soil from the left and right. For this reason, the planted seedlings are unstable, and when exposed to rain or strong winds, they have drawbacks such as difficulty in growing or withering.

[0004] Therefore, an object of the present invention is to solve the above-mentioned drawbacks and to provide a device capable of scraping soil to fix seedlings.

[0005]

In order to achieve the above object, the present invention changes the rotational movement of a sprocket, which is rotated by receiving power from an engine, into vertical movement to move the transplanted nail up and down, and the transplanted nail is moved up and down. In the transplanter for planting seedlings, a sprocket wheel mounting sprocket is provided at a position on the machine body that is behind the sprocket, the sprocket and the sloping wheel mounting sprocket are connected, and a crank arm is attached to the shaft of the sprocket wheel mounting sprocket. , The free crank is further attached to the shaft of the sprocket wheel mounting sprocket, the protrusion is attached to the crank arm, the protrusion is faced to the free crank so that it can be moved toward and away from the sprocket, and the sloping wheel mounting rod is attached to the operating rod hanging from the free crank. , A pair of earth-moving wheels is attached to the rear end of the earth-moving wheel mounting rod located rearward of the transplanting nail.

[0006]

In the earth closing apparatus of the present invention constructed as described above, the crank arm is rotated by receiving power from the engine, and the protrusion of the crank arm engages with the free crank to rise integrally. When the crank arm reaches the lowered position, the free crank falls rapidly due to its own weight earlier than the rotation of the crank arm. At this time, the earth pulling wheels fall while narrowing the gap.

[0007] Due to the above action, the earth pulling ring attached to the free crank slowly rises, then drops rapidly and hits the ridges, destroying the soil around the seedlings and scraping them to bring the soil into close contact with the seedlings. , Secure the seedlings.

[0008]

EXAMPLES Examples will be described with reference to the drawings.

FIG. 1 is an overall view of an implanter embodying the present invention. The left and right front wheels 1, 1 and drive wheels 2, 2 straddle a ridge 3, and the drive wheels 2, 2 move forward. When the worker sets the seedlings 5 such as sweet potato vines in the seedling supply section 4, one by one, the transplanting nails 7 and 8 of the implanting rod 6 set the seedlings 5 in the seedling supply section 4.
Received from and planted in the ridge 3 in sequence.

The implanting rod 6 is attached to a sprocket 9 mounted on a shaft that rotates in conjunction with the power of the implanting machine, via a crank mechanism. The sprocket 1 attached to the earth pulling wheel is mounted diagonally above the sprocket 9 through the endless chain 10.
1 is set.

One end of a crank arm 13 is fixedly attached to the shaft 12 of the sprocket wheel mounting sprocket 11, and the crank arm 1
A protrusion 14 is attached to the other end of 3. Further, one end of a free crank 15 is pivotally attached to the shaft 12 in a free state, and is arranged in a close state to a side surface of the crank arm 13.
One end of the operating rod 16 is connected to the other end of the free crank 15, and a longitudinal groove 16a is formed in the plate-like portion of the other end of the operating rod 16, and the center of the earth retaining wheel mounting rod 17 is formed in the longitudinal groove 16a. The pin 18 of the protrusion provided on the section is slidably inserted. One end of the earthing wheel mounting rod 17 is rotatably attached to the machine body A.
A pair of earth pulling wheels 19 facing the other end at the rear position are rotatably supported. The earth retaining wheel mounting rod 17 is an inverted C-shaped pipe having a narrower space toward the rear of the machine body. The earth pulling wheel mounting rod 17 is divided into a front end side member and a rear end side member.

The tip side member is E-shaped, and the side to be attached to the machine body A is a rod 17a provided horizontally.
Book rods 17b, 17c, 17d are fixed. The left and right rods 17b and 17d have fixed rods 17f of a predetermined length fixed to their tips. A sliding plate 22 having grooves at both ends is fixed to the central rod 17c.

The pair of rear end side members are cylindrical members into which the sliding rods 21 are inserted at one end, and a U-shaped connecting member 17g is fixed to the other end. The connecting member 17g has through holes on both side surfaces thereof, and the connecting rod 17f is inserted into the through holes to connect the front end side member.
At this time, both outer ends of the connecting member 17g are attached with a slight inclination so that they are lower than the inner ends.

Shafts 20 of the earth pulling wheels 19, 19 are axially supported by sliding rods 21, and the sliding rods 21 are attached to the earthing gear mounting rods 17.
It is configured so that it can be slidably inserted into and screwed on. Accordingly, by appropriately adjusting the insertion depth of the sliding rod 21 and inserting the sliding rod 21 into the earth retaining ring mounting rod 17 and screwing it in, the earth engaging wheels 19, 19 can be easily positioned. With the above configuration, the soil gathering wheel 19 narrows the space on the ridges as the free crank 15 rotates, and moves the soil.

The crank arm 13 rotates as the shaft 12 rotates, and when the crank arm 13 is near the bottom dead center, the projection 14 attached to the crank arm 13 engages with the free crank 15 (FIG. 4).
Thereafter, as the crank arm 13 rotates, the free crank 15 is pushed up by the protrusion 14 and moved upward together (FIG. 5).

When the crank arm 13 reaches the top dead center, the free crank 15 is disengaged from the projection 14 and rapidly falls due to its own weight and the weight of the suspended earth pulling wheel 19 and the like ( (Figure 3). The soil gathering wheel 19 is brought into contact with the seedling 5 by the vibration of the fall and the soil scraping effect due to the change in the spacing between the soil gathering wheels 19 caused by the vertical movement of the soil gathering wheel mounting rod 17, and then the crank arm 13 is moved downward. While turning to the dead point, turn the ridges and scrape the soil. Then, when the crank arm 13 reaches the vicinity of the bottom dead center again, the protrusion 14 engages with the free crank 15 and the crank arm 13 and the free crank 15
Move up together again. As a result, the soil gathering wheel 19 is slowly lifted up, and after reaching the top dead center, it falls rapidly to gather the soil onto the seedlings 5. The earth moving wheels 19 and 19 repeat the above-mentioned operation to move up and down, and apply soil one after another to the seedlings transplanted by the transplant nail.

Further, if the number of teeth of the sprocket 9 and the sprocket wheel mounting sprocket 11 are the same, the up and down cycle of the transplanting claws 7 and 8 and the sprocket wheel 19 are the same, and the soil can be surely soiled to the seedling planting site.

[0018]

EFFECT OF THE INVENTION The present invention makes the rotation cycles of the sprocket involved in the vertical movement of the transplanting nail and the sprocket mounting sprocket involved in the vertical movement of the pair of soil retaining wheels in the transplanter coincide with each other.
In addition, the soil ring provided behind the transplanted nail was dropped rapidly while narrowing the interval, so when the transplanted nail moved downward and planted seedlings in the ridges, the soil surrounding the planted seedlings was synchronized with this. Since the seedlings can be closely attached, unstable seedlings can be firmly established immediately after planting, and even if exposed to rain or strong winds, the seedlings can be rooted without dying and the seedlings can be reliably grown. Play.
