Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a transplanting machine for transplanting seedlings such as sweet potato, and particularly to a device for attaching soil to the transplanted seedlings.

[0002]

[Prior Art]

 The conventional device for moving the soil to the seedlings after transplanting is to move the soil by hitting the ridges with a device that moves up and down.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional ones only hit 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, the seedlings have difficulty in growing or die.

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]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a transplanter in which a transplanting nail is moved up and down by changing the rotary motion of a sprocket that is rotated by receiving power from an engine to a vertical motion, and a seedling is planted by the transplanting nail. Install a sloping wheel mounting sprocket at a position on the machine that is behind the sprocket, connect the sprocket and the sloping wheel mounting sprocket, and attach a crank arm to the shaft of the sloping wheel mounting sprocket to attach the sloping wheel. A free crank is further attached to the sprocket shaft, a protrusion is attached to the crank arm, the protrusion is made to face the free crank so that it can be separated from the free crank, and the earthing wheel attachment rod is attached to the operating rod hanging from the free crank. It is configured so that a pair of earth-moving wheels are attached to the rear end of the earth-moving wheel mounting rod located at the rear position.

[0006]

[Action]

 In the earth closing apparatus of the present invention constructed as described above, the crank arm receives power from the engine to rotate, and the protrusion of the crank arm engages with the free crank to move up together. 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 mulch wheels fall while narrowing the gap.

[0007] Due to the above action, the earth pulling ring attached to the free crank slowly rises, then rapidly drops and hits the ridges, collapsing the soil around the seedlings, and pulling the soil to adhere the seedlings to the soil. Let the seedlings settle firmly.

[0008]

【Example】

 Examples will be described with reference to the drawings.

FIG. 1 is an overall view of a transplanter 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 advance. When the worker sets the seedlings 5 like sweet potato vines one by one in the seedling feeding section 4, the transplanting nails 7 and 8 of the implanting rod 6 receive the seedlings 5 from the seedling feeding section 4 and sequentially to the ridges 3. Plant.

The implanting rod 6 is attached to a sprocket 9 attached to a shaft that rotates in conjunction with the power of the implanting machine via a crank mechanism. On the diagonally upper side of the sprocket 9, there is provided a sprocket 11 for attaching a dirt wheel via an endless chain 10.

One end of a crank arm 13 is fixed to the shaft 12 of the earth retaining wheel mounting sprocket 11, and a protrusion 14 is attached to the other end of the crank arm 13. Further, one end of a free crank 15 is pivotally attached to the shaft 12 in a free state, and is arranged in a state of being close 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 bored in the plate-like portion of the other end of the operating rod 16 so that the earthing wheel mounting rod 17 is attached to the longitudinal groove 16a. The pin 18 of the protrusion provided at the center is slidably inserted. One end of the earth-moving-wheel mounting rod 17 is rotatably attached to the machine body A, and a pair of earth-moving wheels 19 facing the other end of the machine body A rear position are rotatably supported. The earth retaining wheel mounting rod 17 is an inverted C-shaped pipe whose interval becomes narrower toward the rear of the machine body. The wide end of the pipe is attached to the machine body, and the sliding bar 21 is attached to the rear end of the space. The earth pulling wheel mounting rod 17 is divided into a front end side member and a rear end side member.

[0012] The tip side member is E-shaped, and a rod 17a provided on the side to be attached to the machine body A is provided horizontally, and three rods 17b, 17c, 17d are fixed to the horizontally provided rod 17a. 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 tubular members into which the sliding rod 21 is inserted at one end, and a U-shaped continuous member 17g is fixed to the other end. The connecting member 17g has through holes on both side surfaces, and the connecting rod 17f is inserted into the through holes to connect the leading 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.

The shafts 20 of the earth pulling wheels 19 and 19 are pivotally supported by the sliding rods 21, respectively, and the sliding rods 21 are slidably inserted into the earthing rod mounting rods 17 and screwed. 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 retaining wheels 19, 19 can be easily positioned. With the above configuration, as the free crank 15 rotates, the soil gathering wheels 19 narrow the gap on the ridges and move 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 protrusion 14 attached to the crank arm 13 engages with the free crank 15 (FIG. 4). As it moves, the free crank 15 is pushed up by the projection 14 and moves upward together (Fig. 5).

When the crank arm 13 reaches the top dead center, the free crank 15 is disengaged from the protrusion 14, and is rapidly dropped due to its own weight and the weight of the hanging wheel 19 or the like ( (Fig. 3). The soil retaining wheel 19 is brought into close contact with the seedlings 5 by the vibration of the fall and the soil scraping effect due to the variation of the spacing between the soil retaining wheels 19 caused by the vertical movement of the soil retaining wheel mounting rod 17, and then the crank arm 13 Rotate the ridges and scrape the soil until it rotates to bottom dead center. 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 upward together again. As a result, the earth-applying wheel 19 is slowly lifted, and after reaching the top dead center, it is rapidly dropped to bring the soil onto the seedlings 5. The earth moving wheels 19 and 19 repeat the above-mentioned operation to move up and down to bring the 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, 8 and the squeeze wheel 19 are the same, and the soil can be reliably soiled to the seedling planting site. ..

[0018]

[Effect of the device]

 The present invention makes the rotation cycle 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 engaging wheels in the transplanter coincide with each other, and further narrows the gap between the soil engaging wheels provided behind the transplanting nail. However, when the transplanted nails moved downward and planted seedlings in the ridges, the surrounding soil surrounding the planted seedlings could be adhered in synchronization with this, causing instability immediately after planting. The seedlings are firmly established, and even if exposed to rain or strong winds, the seedlings can be rooted without dying and the seedlings can be reliably grown.
