Abstract

PURPOSE:To allow a planting mechanism to run without deviating from the transplanting portion of a ridge to either of the lateral directions by pivotally hanging guide rollers engaging with both the lateral side portions of the ridge on the front lateral portions of the main frame in a rotatable state. CONSTITUTION:The lateral running wheels of a transplanter and a front wheel 47 are arranged in the lateral furrows of a ridge and on the transplanting portion of the ridge, respectively, and guide rollers 53 and 53 are engaged with both the lateral sides of the ridge. The front wheel proceeds along the ridge due to the running direction-controlling action of the guide rollers to flatten the surface of the transplanting portion of the ridge with the rotation of the front wheel whereby transplanting seedlings are transplanted at the proper positions of the transplanting portion.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a transplanting machine, for example, for transplanting transplanted seedlings such as lettuce to a transplanting area on a ridge covered with a mulch film. Concerning what goes on.

(Prior Art) Conventionally, in this type of transplanting machine, for example, running wheels are rotatably mounted on the left and right sides of the main body frame, and a multi-layer film is mounted on the sail side of the main body frame in the transplanting part of the ridges. There is a transplanting machine that is equipped with a transplanting mechanism having a burner for thermally drilling a planting hole and a transplanter for transplanting transplanted seedlings into the planting hole at the front and rear sides.

During the transplanting process, the transplanter is run along the ridges continuously or intermittently at predetermined intervals.
Planting holes are sequentially drilled at predetermined intervals using a burner in the transplanted part of the mulch film covering the ridges, and
A transplanted seedling is transplanted into this planting hole using a transplanter.

(Problem to be Solved by the Invention) According to the structure of the transplanting machine, a transplanting mechanism having a burner and a transplanter is installed on the front side of the main body frame, so that during transplanting work, the left and right If the running wheels of the transplanter run over a clod of soil holding down the mulch film covering the ridges in a ridge or fall into a recess in the ridge, the front side of the transplanter may move horizontally relative to the direction of travel. The burner and transplanter of the transplanting mechanism are deviated to one side of the transplanted area on the ridge, and a planting hole is bored to one side of the transplanted area, and the transplanted seedlings are placed in this planting hole. There is a problem that the transplanted seedlings may be transplanted, which is not favorable for the growth of the transplanted seedlings.

In addition, when transplanting on a slope, the front part of the transplanter tends to swing in the direction of the slope, so in such cases, the burner and planting device will deviate to the lower side of the slope, causing the transplanted seedlings to fall. There is a problem in that the transplanted seedlings are sometimes transplanted to one side of the transplanted area on the ridge, which is not favorable for the growth of the transplanted seedlings.

Furthermore, if the surface of the transplanted area on the ridge is swollen and softened or has uneven parts, the transplanted seedlings may not settle properly and may tend to tilt and may be transplanted diagonally. There is a problem that there is.

Therefore, the present invention has been made in view of these problems, and allows the transplanting machine to move along the ridge while leveling the transplanted area of the ridge. The object of the present invention is to provide a transplanting machine that can stably and vertically transplant transplanted seedlings to the middle part of the transplanting part of a ridge while preventing the transplanted seedlings from shifting to one side in the left-right direction. .

Note that W in the figure represents balance weights that are detachably attached to the left and right parts of the planting frame 29 via attachment shafts as necessary.

Next, the operation of the above configuration will be explained.

The left and right running wheels 3 of the transplanter are placed in the left and right bays B of the ridge A so as to straddle the ridge covered with the mulch film F. When the handle 67 is rotated and the screw rod 68 is moved forward and backward relative to the nut body 66, the left and right support arms 38 are adjusted vertically about the support shaft 37 via the operating piece 64, and the front wheel 47 is placed at the optimum height position where it advances over the transplanted portion C of the ridge A via the multi-film F. Further, when the nuts 63 on the left and right support arms 38 are rotated to adjust the forward and backward movement of the screw rods 61 against the coil springs 60, the front wheel 47 is moved relative to the transplant portion C via the left and right protrusions 59 and the supporting frame 42. The horizontal direction is adjusted and set. Further, when the adjustment support frame 55 is adjusted to move forward and backward with respect to the guide piece 44 of the vertical shaft 43 against the coil spring 58, the left and right swing arms 48 are moved up and down about the axle 46, and the left and right guides The rollers 53 are engaged at optimal positions on the left and right side surfaces of the ridge A covered with the mulch film F.

In the case of transplanting work on flat land, the operating handle 20 is rotated backwards about the horizontal axis 19 against the spring 24, and the locking pin 22 of the operating handle 20 is moved to the support frame 13. Insert into the locking hole 14 in the center. As a result, the operating handle 20 is urged forward by the biasing action of the spring 24, and the locking pin 22 is inserted and held in the locking hole 14. Since the locking pin 22 is formed smaller than the locking hole 14, the locking pin 22 is inserted and held in the locking hole 14 so as to be swingable.

Next, when the engine 4 is driven, the input shaft 8 of the transmission 5 is rotated via its output shaft 6, pulley 7, endless belt 10, and pulley 9, and the power from the mission 5 is transmitted to the left and right sides via the axle 2. The running wheels 3 are rotationally driven in the running direction, and the output shaft 19 and pulley 80
, an endless belt 81, a pulley 76, a rotating shaft 77, a sprocket 75, an endless chain 78, and a sprocket 73.

Then, the transplanting machine is moved along the ridge A while straddling the ridge Δ by the rotational drive of the left and right running wheels 3, but at this time,
The left and right guide rollers 53 are in pressure contact with the left and right side surfaces of the ridge A and rotate without rotating, so the running direction control action of the left and right guide rollers 53 causes the front wheels 47
The traveling direction of the transplanter is determined, and the transplanter is advanced along the ridge A, and the front wheels 47 are rotated while flattening the surface of the transplanted portion C of the ridge A through the mulch film F.

In addition, while the transplanter is moving along the ridge A, if the left and right running wheels 3 are moved up and down by the unevenness of the groove B, for example, by the clod of earth pressing down the mulch film in the groove B, this left and right running wheel 3 The traveling frame 1 on which the wheel 3 is mounted is rotatably connected to the planting frame 29 via the bearing body 28 and the rotation center shaft 12, and is connected to the locking hole 14 of the support frame 13. Since the locking pin 22 is swingably supported by the locking pin 22, it is swingable and tilted in the left and right directions with respect to the horizontal plane in the advancing direction independently of the planting frame 29, but the planting frame 29 is not affected by the tilting movement. It continues to advance in a horizontal state toward the transplanted portion C of the ridge A without being tilted.

Further, as the transplanter advances, the drive shaft 74 is rotationally driven as described above, so that the link machine 4fji89 is rotated up and down at predetermined intervals, and the transplanter 90 and the thermal perforation body 93 are moved up and down. The transplanted seedlings a of the soil block S are vertically transplanted one after another at predetermined intervals in the transplanting part C of the ridge A. That is, by the upward rotation of the link mechanism 89, the transplanter 90 is raised to the seedling receiving position directly below the turntable 85, and the seedling storage body in the upper part of the transplanter 90 is moved through the push pin 94 and the operating rod 95. 86, the shutter 88 is opened, and the transplanted seedlings a in the soil block S in the seedling container 86 are transferred to the transplanter 9.
The transplanter 9 which was dropped into the soil block S and accommodated the transplanted seedling a of the soil block S by the untimely rotation of the link mechanism 89.
0 and the thermally perforated body 93 are rotated downward, and the thermally perforated body 93 contacts the widthwise middle part of the mulch film F in the transplanted part B of the ridge A to thermally perforate the transplanted hole f. A transplanter 90 having transplanted seedlings a of soil block S is
The thermal perforator 93 pierces the exposed soil in the pre-drilled transplant hole f by the previous operation, forming a transplant hole.
At the same time, the transplanter 90 is raised and opened by the operation of the link mechanism 89, and the transplanted seedling a of the soil block S is vertically transplanted into the transplant hole. Furthermore, the drive shaft 7
4, the link mechanism 89 is rotated again, and the transplanter 90 is closed in preparation for receiving the transplanted seedling a from the soil block S, and the turntable 85 is closed. The empty seedling container 860 that has been rotated and has dropped the transplanted seedlings a, and the seedling container 86 that has the transplanted seedlings a of the next soil block S is transferred to the transplanter 90.
The soil block S is moved and stopped directly above the raised seedling receiving position in preparation for supplying the transplanted seedlings a to the soil block S.

In this way, the transplanter moves along the ridge A and drills transplant holes at predetermined intervals in the transplant section C to the ridge, and sequentially inserts the transplanted seedlings a of the soil block S into each of the transplant holes.
is transplanted vertically.

Next, in the case of transplanting work on a slope, if the left and right running wheels 3 of the transplanter are placed in the area B of the ridge A so as to straddle the ridge A covered with the mulch film F, the entire transplanter will be It is installed in a state where it is inclined in the left-right direction with respect to the inclination direction of the slope, that is, the direction of travel.

Therefore, when the operating handle 20 is rotated backwards about the horizontal axis 19 against the spring 24 and also in a direction opposite to the direction in which the transplanter is tilted, the bracket 1 is rotated 17 and rotated. Interlocking rod 3 via shaft 16
0 is rotated in the rotation direction of the operating handle 20, and the planting frame 29 is rotated independently from the traveling frame 1 via the bearing body 28 by the interlocking rod 30.
It is interlocked and rotated about the rotation center @12 in the direction opposite to the direction of inclination. Then, the planting frame 29 is rotated horizontally, and the operating handle 20 is moved along the support frame 13 with the return force of the spring 24 at the horizontal position 19.
The locking pin 2 of this operating handle 20 rotates forward to the side.
2 into a predetermined position in the left and right direction of the support frame 13 through the locking hole 1
Insert within 4. As a result, the planting frame 29 is angularly adjusted independently with respect to the traveling frame 1, and its traveling posture is corrected to a horizontal position, and the operating handle 20 is urged forward by the biasing action of the spring 24, and its engagement The locking pin 22 is inserted and held in the locking hole 14, but since the locking pin 22 is formed smaller than the human size of the locking hole 14, the locking pin 22 cannot swing into the locking hole 14. Can be inserted and held freely.

Therefore, the transplanter runs with its running frame 1 tilted and swings depending on the condition of the groove B;
The planting frame 29 is run horizontally with respect to the transplanting part C of the ridge A, and as a result, the transplanted seedlings a of the soil block S are perpendicular to the transplanting part C, as in the case of the transplanting work on the flat land. It is transplanted into a state.

〔Effect of the invention〕

According to the present invention, since the guide rollers that engage with the left and right sides of the ridge are rotatably mounted on the front left and right parts of the main body frame, the traveling direction of the front wheels is controlled by these left and right guide rollers. The machine can be advanced along the ridge, and this planting mechanism can advance without shifting to one side in the left-right direction with respect to the transplanted part of the ridge.
In addition, since the front wheel is rotatably provided in the front part of the main body frame, it is possible to proceed while leveling the ground reliably so that transplanted seedlings can be easily transplanted to the transplanting part of the ridge. Since the position of the front wheel is adjustable in the downward direction, the front wheel can be reliably adjusted and set according to the height of the transplanted part of the ridge, the planting depth of the transplanted seedlings, and the soil leveling pressure. It is possible to easily set the transplanted seedlings in a state where it is easy to transplant using the mechanism, and therefore, the transplanting mechanism can be prevented from shifting to one side in the left-right direction with respect to the advancing direction, and the transplanted seedlings can be placed in the middle of the transplanted part of the ridge. It is possible to provide a transplanter that can be stably and vertically transplanted.
