2. Description of the Related Art A seedling transplanter of this type is disclosed in Japanese Unexamined Patent Publication No. 2-20.
As shown in Japanese Patent No. 3706, a planting mechanism including a planting arm and a planting claw is arranged on the rear side of the planting case, and the planting mechanism is driven by shaft transmission from the rear of the planting case. In this way, the seedlings on the seedling mounting table, which tilt forward and tilt, are sequentially taken out and planted.

[0003]

In the above-mentioned prior art, the planted seedling at the time of planting on the mud surface has a position in the front-rear direction with respect to the planting case approximately corresponding to the front-rear central portion of the planting case. Due to the positional relationship, if the planting part and the planted seedlings after planting may contact in the left-right direction due to horizontal slippage due to unevenness of the field or changes in softness or correction of steering, etc. However, there was a strong possibility that the plant could be caught by the side of the planting case, which had a relatively high degree of unevenness, and dragged, and that the planting posture and position would be disturbed if the seedling was knocked down.
The present invention is intended to eliminate the above-mentioned inconvenience by a simple structure.

[0004]

To achieve the above object, the present invention provides a seedling planting mechanism in a state where power is transmitted from the lateral side of the planting case, and the seedling planting mechanism is provided. Provided with a guide member for preventing contact between the lateral side surface of the planting case and the planted seedlings after planting, from the part where the seedlings are taken out by the attachment mechanism to near the rear end of the planting case. It is characterized by.

[0005]

According to the above-mentioned characteristic structure, when the planting portion shifts in the left-right direction due to the steering operation of the traveling machine body or the slip in the left-right direction, the planting seedling is not the side wall of the planting case and has no unevenness or a catch Since it comes into contact with the guide member, it is impossible to eliminate the lateral pressing external force that acts on the planted seedlings, but it is only pushed and temporarily pushed left and right, and it is hooked as in the past. It will not be dragged and the planting posture and position will not be significantly disturbed.

[0006]

As a result, the planting condition of seedlings can be improved during curved traveling and working traveling involving left and right slips by a simple modification by disposing a guide member at a lateral position of the planting case. It was

The following is a description with reference to the drawings of a case where the embodiment of the present invention is applied to a seedling transplanter for strawberries. FIG. 4 shows a plant for transplanting strawberry seedlings, and FIG. 1 shows the planting portion thereof. The planting device 2 for planting seedlings is movably connected to the rear portion of the traveling machine body 16 via a link mechanism 17, which is a frame. Seedling stand 4 that reciprocally moves laterally with a constant stroke with respect to combined planting case 3, planting mechanism 6 for cutting and planting seedlings one by one from seedling take-out port 5 at the lower end, a plurality of leveled floats 7, etc. Is equipped with. At the lower part of the seedling placing table 4, there is provided an endless rotating belt type vertical feeding device 8 with a protrusion that vertically feeds the placed seedlings by a predetermined amount toward the seedling taking-out port 5 at a stroke end of lateral movement, Above the planting mechanism 6, a seedling holding mechanism 11 is provided by an auxiliary claw 10 that enters the lower end of the seedling and pushes and holds it toward the seedling take-out port 5 prior to the operation of the planting claw 9. The planting mechanism 6 includes a planting claw 9 and a planting arm 1.
2. The seedling pushing tool 13 and the like, which are arranged in a lateral position of the planting case 3 in a state in which power is transmitted. Then, as shown in FIG. 1 to FIG.
The wire rod for preventing contact between the lateral side surface of the planting case 3 and the planted seedlings after planting is bent from the portion of the seedling taking-out guide 14 attached to the plant to near the rear end of the planting case 3. The guide member 1 formed is provided. The guide member 1 is bent over the front of the seedling take-out guide 14 to the extent that it covers both left and right sides of the planting point of the planting claw 10, and the rear portion of the adjacent guide member 1 is integrally connected. It is configured as a two-piece integrated type and is bolted to the side wall 3a of the planting case 3 via a bracket 15. As shown in FIG. 1, the guide member 1 is provided at a height position above the bottom surface of the ground leveling float 7, and the front part is gently sloping forward and inclined. As a result, as shown in FIG. 3, the guide member 1 exists between the planted seedling immediately after planting and the planting case 3 in the left-right direction.

Next, the seedling holding structure will be described. Figure 5
As shown in FIG. 7, a holding plate 18 that pushes from the rearmost portion of the seedling group to prevent the seedlings mounted on the seedling mounting table 4 from falling.
And a pair of left and right guide rods 2 supported by the supporting vertical wall 19 and arranged in parallel with the seedling transfer direction of the seedling placing table 4.
0, 20 are fitted, and are slidable along the guide rods 20, and a pair of guide rods 20
Is configured to be capable of swinging upward about a left and right shaft-shaped fulcrum P provided at the lower end thereof. The pair of guide rods 20 is an integrated product having a U-shape in a plan view with the upper ends thereof connected, and the holding plate 18 presses the seedlings by the downward biasing force due to its own weight.

The lifting device A is constructed as follows. That is, the sprockets 22, 22 are attached to both ends of the support frame 21 pivotally supported around the fulcrum P, and the projection 2 capable of abutting the presser plate 18 across them.
A chain 24 provided with 3 is wound, and a handle 25 for rotating operation is attached to the upper sprocket 22. The protrusion 23 is composed of a bar that is installed over the left and right chains 24. The rotating shaft 26 of the upper sprocket 22 is used for all the upper sprockets 22 of the side-by-side seedling placing table 4.
It also serves as the rotating shaft of the chain, and one of the handles 25 provided at the left and right ends of the seedling placing table 4 is manually operated to manually operate the chain 2.
When the upper side of the pressing plate 4 is driven toward the handle 25 side, the projections 23 come into contact with the pressing plate 18 from the lower side and move the pressing plate 18 together, so that the pressing plates 1 of all the strips are moved.

It is possible to swing and open upwards around it, and its open posture (Fig. 6).
A hip bending link mechanism 27 for maintaining the above (see reference) is provided.
As shown in FIG. 4, the steering wheel 25 arranged at the upper end portion of the seedling placing table 4 is located immediately behind the driver's seat 28. Further, a receiving stay 29 that opens upward is attached to the upper side surface of the pressing plate 18, and the handle 25 is turned to rotate the pressing plate 18.
When the guide rod 20 is lifted and set, the receiving stay 29 is fitted into the rotary shaft 26 of the pulling device A in the open posture, and the guide rod 20 can be maintained in the open posture. The opening width L1 of the entrance portion of the receiving stay 29 is smaller than the width L2 of the inner portion of the receiving stay 29 so that the pressing plate 18 can be easily prevented from accidentally falling. On the contrary, the guide rod 20 may be lifted to receive the rotary shaft 26 by the receiving stay 29, and the lifting device A may be rocked together and lifted. The pulling device A and the guide rod 20 are opened to facilitate the work of placing and inserting the feeding seedling box 30 on the seedling placing table 4.
