Description

[Detailed description of the invention] The present invention has a fixed arrangement of a spare seedling stand that supports spare seedlings to be supplied to the seedling stand that is moved back and forth, and a clutch mechanism that stops the movement of the seedling stand. Regarding rice transplanters.

In such a rice transplanter, the spare seedling stand is fixedly provided, so compared to a machine in which the spare seedling stand and the seedling stand are installed in tandem, the machine body is subject to greater vibration as the seedling stand moves back and forth. This makes it possible to minimize the occurrence of disadvantages such as seedlings being fed, but on the other hand, it becomes difficult to supply spare seedlings.

In other words, when supplying spare seedlings, the seedling rack is stopped at a position corresponding to the spare seedling rack so that the spare seedlings can be easily fed onto the seedling rack. In order to operate the clutch mechanism to a position corresponding to the base and stop the machine, it is difficult to know the timing of the clutch operation, and an unskilled person has to repeat the operation many times.

The present invention aims to solve the above-mentioned problem, and in a rice transplanter having a officially registered structure, there is a mechanism between the seedling stand and the spare seedling stand or the fixed frame, in which the moving force of the seedling stand is and an abutment linkage mechanism that presses and displaces the movable member, and the movable member and the clutch mechanism are interlocked and connected to automatically stop the seedling stand at a position corresponding to the preliminary seedling stand. , and the abutment linkage mechanism is configured to be freely switchable between a linkage state and a linkage release state.

In other words, when replenishing seedlings, the seedling rack can be automatically stopped at a position corresponding to the spare seedling rack by simply switching the contact linkage mechanism to the linked state, so even an unskilled person can quickly load the seedlings. In particular, according to the present proposal, the operating force for disengaging the clutch is obtained from the moving force of the seedling stand, so for example, a hydraulic cylinder or electromagnetic Tsuremade is used for clutch operation. Compared to using a special drive mechanism, it is cheaper and easier to implement, and has extremely large practical advantages.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figure 1 shows a side view of a riding rice transplanter, showing a pair of left and right rear propulsion wheels 1.1 that touch down on a hard surface and move forward, and a pair of left and right steering front wheels 2, 2 that are operated to change direction. A seedling planting device 3 is connected to the rear of the traveling machine.

As the seedlings advance, the rear seedling planting device 3 moves the seedlings up and down from the seedling group placed on the inclined seedling platform 4, which is reciprocated with a constant stroke in the horizontal direction, from the lower end of the seedling platform to the mud. The seedlings are sequentially taken out one by one by a plurality of planting claws 5 that operate in a circular manner and are planted in the field.

A spare seedling rack 6 that supports spare seedlings to be supplied to the seedling rack 4 is fixedly provided at a position continuous with the upper end of the seedling rack 4, and when replenishing seedlings, the seedling rack 4 is used as a standby seedling rack. It is constructed as described below in order to automatically stop at a position corresponding to the stand 6.

That is, as shown in FIGS. 2 and 3, a pair of left and right swinging arms are mounted on the upper back of the seedling stand 4. a, 7
A pair of left and right abutting pieces 8a, 8b are provided on the side end of the seedling pedestal of the preliminary seedling pedestal 6 so as to be able to swing laterally. are provided, so that both arms 7a, 7b and circumferential contact piece 8a
.

8b constitutes a contact linkage mechanism that presses and swings the left arm 7a when the seedlings are moved, and presses and swings the right arm 7b when the seedling tray moves to the left.

The abutting pieces 8a and 8b are pivotably supported on the preliminary seedling resting platform 6, so that the abutting pieces 8a and 8b are in a contacting working position protruding toward the seedling resting side and in a non-working position in which they are retracted below the preliminary seedling resting stage 6. The abutment linkage mechanism is configured to be able to switch freely between the positions, and the abutment linkage mechanism is configured to be switched between the linkage state and the linkage release state by this attitude change, and the circumferential abutment pieces 8a, 8b It is wire-linked to a swinging lever 10 provided near the lever 10, and is configured to be switched between the two positions by swinging the lever 10 back and forth.

Further, the swinging arms 7a, 7b are connected by wire to an operating arm 12 of a planting clutch (not shown) provided in the planting mission case 11, and the swinging arms 7a,
The planting clutch is configured to be operated by disengaging the planting clutch by the swinging of 7b, and the pressing and swinging of the swinging arm 7at7b by the abutting pieces 8a and 8b causes the seedling rest 4 to correspond to the preliminary seedling rest 6. It is configured to be performed when the position is reached.

According to the above configuration, during normal seedling planting work, the abutment linkage mechanism is operated to the disengaged state, and when supplementary seedlings are supplied, if the abutment linkage mechanism is switched to the linkage state, the seedling loading platform 4 When the seedling tray 4 reaches the position corresponding to the preliminary seedling tray 6, the planting clutch is automatically disconnected and the operation of the seedling tray 4, planting claws 5, etc. is stopped.

In carrying out the present invention, it will be more convenient if the driving transmission clutch is also disengaged at the same time using the contact linkage mechanism of the present invention.

Further, a mechanism for detecting the amount of seedlings placed on the seedling stand 4 may be provided, and the abutting linkage mechanism may be automatically switched from the disengaged state to the linked state based on the detection result.

Alternatively, an abutment linkage mechanism may be provided between the seedling stand 4 and the fixed frame.

In addition, when the present invention is implemented, when the contact linkage mechanism is provided between the spare seedling rest 6 and the seedling rest 4, the fixed position of the spare seedling rest 6 can be changed and adjusted in the direction of movement of the seedling rest 4. If configured freely, the stopping position of the seedling stand 4 can be adjusted in the direction of movement, and various ways of use can be selected as appropriate, such as stopping at the end of the stroke or stopping at the center of the stroke. It's fine.
