However, since the mounting structure of the auxiliary seedling mounting table is a direct mounting structure in which the base of the column of the auxiliary seedling mounting table is directly screwed to the machine frame, the auxiliary seedling mounting table is mounted on the user side. Since it is difficult to attach the stand separately, the spare seedling stand is shipped with the spare seedling stand already assembled to the traveling machine at the time of factory shipment, so the packaging of the transplanter is bulky and the spare seedling stand is damaged during transportation. However, there are drawbacks such as reduced transport efficiency. Also, when trying to perform maintenance work on the engine part etc. by opening the bonnet, the work of removing and installing the above-mentioned preliminary seedling mount is a complicated work such as attaching and detaching the mounting screws etc. on the support base side one by one. In addition to the above, the positioning of the columns is likely to be insufficient, and the reassembled preliminary seedling mounting table has problems such as vibration and shaking during the work.

[0004]

In order to solve the above-mentioned conventional problems, the auxiliary seedling mount of the transplanter of the present invention has a spare seedling mount attached to and detached from a traveling machine body having a planting device through columns. In a transplanter that can be mounted so that a plurality of the stanchions are provided upright and formed, and the plurality of stanchions are respectively inserted into the stanchions fixed to the traveling machine body so that the preliminary seedling mounting table can be attached. I am configuring.

Further, the columns of the preliminary seedling stand and the column receivers are composed of a pair of columns and a pair of column receivers, and one column is fitted and supported by one column support while the other column is fitted and supported. It is characterized in that the support pillar is configured to be fitted into the other support bracket.

In front of the traveling machine body 1c, a step portion 1d is provided on both sides of the bonnet 3, and a spare seedling stand 6 is erected and supported by the outer surface of the machine body frame 10 in the front-rear direction. The mat-shaped seedlings can be placed on the same height as the mat seedlings. As shown in FIGS. 1 and 4, the preliminary seedling placing table 6 has a pair of left and right columns 61, 62 downward from both sides of the upper horizontal rod 60 by forming a pipe rod downward in a U shape in a side view. And a preliminary seedling placing plate 6a is attached to the columns 61 and 62 in an appropriate number of stages to integrally form a frame.
The spare seedling stand 6 is provided by inserting the 62 into the left and right support posts 71 and 72, which are erected and fixed from the machine body frame 10 via the mounting arms 7a and 7b, respectively by the mounting configuration described later.
Is detachably attached to and supported by the traveling machine body 1c in the form of an assembly.

A wide heat shield plate 65 for shielding exhaust heat or radiant heat from the engine 2 is provided at the opposite sides of the bonnet 3 of the preliminary seedling stand 6 constructed as described above, with the columns 61, 62.
By forming the attachment between them, the preliminary seedlings are prevented from being heated and the rigidity of the frame is increased. Further, the pillar supports 71, 72 are connected and reinforced by connecting with a connecting rod 73.

When mounting the preliminary seedling mounting table 6, the left and right struts 61, 62 have substantially the same length at the lower ends of the pipes, and the stanchion support 7 is provided in the lower end of the right stanchion 62.
An extension rod 66 for positioning that can be fitted into the inside of the column 2 is inserted and fixed, and is formed so as to extend downward from the end of the left column 61.

An engaging groove 67 is formed in a lower end portion of the extension rod 66 of the support column 62 so that a stopper 8 of a stopper mechanism S formed on a base portion of a support column 72 described later can be engaged and disengaged. I am trying to do it. Further, one of the columns 61 is adapted to be externally fitted to a rod-shaped column receiver 71 which is vertically erected and fixed on the left side, and the amount of the insertion is approximately the outer circumference of the column support 71 and the upper end of the other column support 72. Stopper 7 protruding at the same height
The lower limit position is regulated by 1a.

The stopper 8 is slidably supported by a holder 85 protruding from the support 72 in a state in which the stopper piece 81 is fixed to the shaft portion and the spring 82 is fitted and inserted. As a result, when the extension rod 66 of the support rod 62 is fitted and inserted into the support rod receiver 72, the stopper 8 engages with the engagement groove 67 of the extension rod 66 at the fixed position to prevent the support rod 62 from coming off. I am trying.

The preliminary seedling placing table 6 constructed as described above corresponds to the pair of columns 61 and 62 formed at the lower end thereof, and the column supports 71 are provided upright from the body frame 10 side. It is possible to easily and accurately stand and support the columns 61 and 62 on the columns 72 and 72 by inserting the columns 61 and 62 from above. That is, in order to attach the preliminary seedling mounting table 6, first, one of the columns 62 formed to be long is inserted into the one column support 72 from above, and when the preliminary seedling mounting table 6 is temporarily supported, the other column 61 is set to the other. By aligning and fitting the support post 71, the support 71 is fitted and supported at an appropriate position. Also,
By engaging the stopper 8 with the engagement groove 67 of the column 62, the preliminary seedling stand 6 is prevented from coming off at the base side of the column receiver 72.

Further, when it is desired to remove the preliminary seedling placing table 6 from the traveling machine body 10 during maintenance work of the engine 2 or during transportation of the transplanting machine 1, the stopper 80 is pulled to operate the stopper 8. Remove from the engagement groove 67,
By performing the operation reverse to the operation described above, one of the columns 61
After pulling out the above, the other pillar 62 is detached,
The spare seedling stand 6 can be easily removed from the traveling body 10.

As described above, the work for attaching and detaching the preliminary seedling placing table 6 is carried out while the worker is standing upright on the side of the machine while temporarily supporting the long-supported pillar 62 as the mounting reference side on the pillar receiver 72. Since the other supporting pillar 61 can be appropriately rotated with this as a fulcrum, the supporting pillar support 71 can be positioned and fitted and mounted, so that the heavy preliminary seedling mounting table 6 can be easily and efficiently attached and detached. In addition, since the pillar supports 71 and 72 are erected upward from the machine body frame 10, when the spare seedling stand 6 is mounted, the work can be performed in a crouched posture and in a narrow area, unlike the conventional one. It is possible to perform in a stable condition without doing it.

Further, according to the above-mentioned assembly structure, the column 6
Even if there is a variation in processing accuracy between the first and second support posts 71 and 72 and the support posts 71 and 72, the other support column 61 can be easily operated in the temporary support state to easily insert and accurately assemble the support columns. There is an advantage that it can be manufactured at low cost without requiring processing accuracy.
