Description

[Detailed Description of the Invention] Conventional riding rice transplanters were not equipped with a tool box, which was inconvenient when adjusting or maintaining the planting device during work.

In addition, the body of the riding rice transplanter tilts or vibrates strongly during operation, and when pine seedlings with heavy soil are stacked in multiple tiers, an extremely large load is placed on the loop frame that constitutes the support of the auxiliary seedling stand. This resulted in drawbacks such as cracks appearing at the base of the loop frame.

The present invention provides a tool box that is always provided in the riding rice transplanter, so that adjustments and maintenance of the planting device and the machine can be performed easily and quickly during the work, and the tool box can be used to provide assistance against vibrations, tilting, etc. of the machine body. The purpose is to provide an auxiliary seedling stand for a riding rice transplanter that can improve the strength of the seedling stand, and a loop frame 7 is erected on the side of the machine body, and a seedling mounting frame 8 is attached to the loop frame 7.
This riding rice transplanter is characterized in that the base of the loop frame 7 is welded to a tool box 13 that is integrated with the machine frame.

The embodiments shown in the drawings will be explained below.
1 is equipped with an engine 2 in the front, a control section 3 in the middle, and a seedling platform 4a that reciprocates left and right in the rear.
The aircraft is equipped with a planting device 4 that can be moved up and down, consisting of five planting frames 4b, . 5, 5, respectively, and on both sides of the engine 2 there are auxiliary seedling stands 6, each equipped with a one-stage seedling mounting frame 8,
6 is provided.

The auxiliary seedling stands 5 on both sides of the cockpit 3a are constructed by fixing two upper and lower seedling mounting frames 8, 8 to a downward U-shaped loop frame 7, with the lower end of the loop frame 7 facing upward. The downward U-shaped receiving frame 9 welded to the left and right supports 10,
It is fitted and screwed into a horizontal frame 11 and a square frame 12 which are integral with the frame 10.

The tool box 13 has a lid 13 on the top of the main body 13a.
The entire side surface of the main body 13a is welded to the base of the loop frame 7, and a portion of the lower surface is welded to the receiving frame 9 to form an integral body.

Therefore, the planting work can be carried out with the tools necessary for adjusting or servicing the planting device 4, the transmission device, etc. stored in the tool box 13, and the largest bending moment can be applied to the loop frame 7. Such a base can be firmly held.

Further, as shown in FIGS. 5 to 7, the seedling mounting frame 8 is raised to a position facing the side plate of the seedling box on which the side rods 8a are placed, and the side rods 8a of the loop frame 7 are
Fix the presser rod 8b at the same height as a, and
When b and the side rod 8a are bent inward, the seedling box placed thereon will be held between the presser rod 8b and the side rod 8a because the rods 8a and 8b are made of elastic rods. This prevents the aircraft from falling even if it vibrates or tilts significantly when going over a ridge.

Furthermore, the auxiliary seedling stand 6 on the side of the engine 2 is attached to the loop frame 14 as shown in FIGS.
The loop frame 14 has a support rod 15 at the lower front side that loosely fits into a hole in a receiver 17 fixed on the fender 16, and a support rod 18 at the lower end of the rear end is attached to a high support rod 19. A hook 22 is attached to a fulcrum shaft 21 rotatably supported on the upper part of the receiver 19.
When the seedling box containing spare seedlings is placed on the seedling tray frame 8, if the hook 22 is removed from the fulcrum shaft 21, the seedling tray frame 8 can be held in a stable approximately horizontal position, and the auxiliary seedlings can be placed on the seedling tray frame 8. When replenishing the platform 4a, loop frame 1
4 and hangs the hook 22 on the support rod 18 for support, the operator stands on the deck of the control section 3 and can easily take out and replenish the pine seedlings together with the seedling box.

Further, the angle of the seedling mounting frame 8 can be changed or adjusted depending on the direction of sunlight, etc., or when the machine body is tilted significantly as when the machine body is put into a field.

As described above, the present invention has a loop frame 7 erected on the side of the machine body, and a seedling mounting frame 8 is attached to the loop frame 7.
In the riding rice transplanter equipped with this, the base of the loop frame 7 is welded to the tool box 13 that is integrated with the machine frame, so tools necessary for maintenance or adjustment of each part can be placed in the tool box at any time during work or while driving on the road. It is convenient because it can be carried around, and the tool box 13 can be attached using the dead space at the base of the auxiliary seedling stand 5, so the machine body does not become large and does not become an obstacle to work or operation. do not have.

Furthermore, since the loop frame 7 supports a plurality of seedling boxes and heavy pine seedlings with soil, an extremely large bending moment is applied to its base, but the base of the loop frame 7 is welded to a tool box 13 that is integrated with the machine frame. Therefore, even if the machine body vibrates or tilts significantly, the bending of the loop frame 7 is suppressed, the seedlings can be supported in a stable state, and the soil on the seedling bed can be prevented from shrinking and being damaged. This can prevent cracks from forming at the base of the base.
