[Prior art]

In the final planting process, this type of riding rice transplanter needs to ensure at least a width equivalent to the distance between the ruts of the running wheels for the machine to move forward so as not to trample on the already planted seedlings in the field. The number of rows to be planted in the final planting process must be set to the maximum planting width that corresponds to the distance between the tracks of the running wheels, that is, the total number of rows on the seedling table installed in the rice transplanting device must be planted at the same time. .

For this reason, when the pre-planting process before the final planting process involves planting a partial number of rows instead of planting all the rows, conventionally, seedlings are placed on the seedling stand corresponding to the extra rows that do not need to be planted. The seedling stopping device, which is located at Since the device had to be released manually, not only was it troublesome for the operator to manually operate the device, but the device often forgot to release the device before starting the final planting process, making it difficult to plant seedlings using the entire number of rows in the final planting process. There was a problem that it was not possible.

A seedling vertical feeding mechanism 17 consisting of a conveyor belt or the like is provided on the bottom plate of each seedling mounting table 12.
It is driven by an intermittent drive mechanism (not shown) configured to vertically feed the pine seedlings 28 on the seedling mounting table 12 by a predetermined amount of one plant only when the seedling table 2 moves to the left and right ends, Further, below the rice transplanting device 5, left and right floats 18, 18 and a center float 19 that slide on the rice field are respectively arranged.

As shown in FIGS. 3 and 4, each seedling mounting table 12 has a pair of holes 21, 21 bored in the bottom plate 20 below the lower end of the vertical seedling feeding mechanism 17. The hole 21 is provided on the back surface of the bottom plate 20.
The boxes 22 are fixed to each other with the center .
A seedling stopping mechanism 25 is housed in this box 22, and this seedling stopping mechanism 25 is
Below the box 22 is a solenoid coil 23.
A movable rod 24 is fixed to the solenoid coil 23 and is movable up and down with respect to the solenoid coil 23, a protrusion pin 26 is fixed above the movable rod 24, and a protrusion pin 26 is provided between the movable rod 24 and the bottom plate 20 of the seedling table 12. It is composed of a return spring 27 and the like.

This seedling stopping mechanism 25 includes a solenoid coil 23
By turning ON, the protruding pin 26 protrudes into the soil of the pine seedling 28 as shown in FIG.
The pine seedlings 28 can be regulated to a stopped state where they are not fed vertically, and the solenoid coil 2
3 is in the OFF state, the protrusion pin 2
6 is removed from the bed of the pine seedlings 28 by the urging force of the return spring 27, as shown in FIG. 3, and the pine seedlings 28 are ready to start vertical feeding.

Five actuation switches 29, 29, . It is placed on the side of the
Further, on the side of the driver's seat, a hydraulic operating lever 30 for operating a hydraulic expansion/contraction mechanism 31 connected to the lifting device 4 is pivotally supported around a support shaft 32.
This hydraulic operating lever 30 is provided so as to be swingable and fixed in a raised U position and a lowered D position with a neutral position N as the center. The other end of the connecting wire 34, one end of which is rotatably supported at the tip, is connected to a hydraulic switching valve (not shown) that controls the hydraulic expansion and contraction mechanism 31, and the hydraulic operating lever 30 has a hydraulic operating lever. An interlocking switch 35 is provided opposite to the lever 30, which is turned on when the lever 30 is in the raised U position.

It is arranged so as to be linked to a control mechanism 37 such as a microcomputer.

Therefore, in the final planting process, the entire number of rows installed in the rice transplanter is required to be planted, so as shown in Figure 7, an extra number of rows was generated in the previous planting process. In this case, the operation switch 29 located at the position corresponding to the seedling mounting table 12 on which you want to stop the vertical feeding of the pine seedlings 28 can be turned to the ON position while sitting in the driver's seat 6. A set of two solenoid coils 2
3 and 23 are in the ON state, and the protrusion pin 26 is in the fourth position.

The ON state is maintained through 6.

The seedling stopping mechanism 25 in operation is controlled by a hydraulic operation lever 30 that operates the hydraulic expansion and contraction mechanism 31.
It can be released by raising the button twice. In other words, even if the seedling stopping mechanism 25 is activated by operating the operation switch 29 and the vertical feeding of the pine seedlings 28 is stopped, the seedlings from the pine seedlings 28 remaining between the movement trajectory K of the tip of the planting rod and the apron 13 Since the supply continues for a maximum of 5 meters in terms of planting distance, as shown in Figure 7, the operating switch 29 is turned ON at position A before the end of the pre-pre-planting process (before turning). There is a need to.

When turning the machine 2 from the A position to proceed to the pre-planting process, the hydraulic control lever 30 is raised and operated to the U position to raise the rice transplanting device 5 and turn the machine 2. 35 is turned on, the control circuit of the control mechanism 37 counts the "number of times I", and when moving from the pre-planting process to the final planting process, the hydraulic operating lever 30 is raised to the U position and the rice-transplanting device is turned off. 5 and turns the body 2, the control circuit of the control mechanism 37 counts the number of times, and as a result, the control mechanism 37 cuts off the energization to the solenoid coil 23, causing the pine seedlings 28 to The seedling stopping mechanism 25 that is operating in the stopped state is automatically released by twice operating the hydraulic control lever 30 when the rice transplanting device 5 is raised and lowered when the machine is turned, and the seedling stopping mechanism 25 is automatically released when the rice planting device 5 is raised and lowered when the machine is turned. Vertical feeding of seedlings can be started.

Therefore, there is a problem that manual operation of the seedling stopping device by an operator as in the past is troublesome.
Furthermore, it is possible to simultaneously solve the problem that when the seedling stopping device is forgotten to be released before the start of the final planting process, it becomes impossible to plant all the seedlings in the final planting process.

[Effect of idea]

In short, the pine seedling stopping device for riding rice transplanting of the present invention is a riding rice transplanter in which the rice transplanting device can be raised and lowered by a hydraulic telescopic mechanism, and the seedling stopping mechanism provided on each seedling mounting table of the rice transplanting device is activated. By operating the switch, the vertical feeding of the pine seedlings placed on the seedling mounting table is stopped, and the seedling stopping mechanism is released by twice operating the hydraulic operating lever that activates the hydraulic expansion and contraction mechanism. Therefore, by simply operating the operating switch in the pre-pre-planting process before the final planting process using the riding rice transplanter, it is possible to remove the excess seedlings on the seedling stand without needing to plant them during the pre-planting process. The stop mechanism can be activated to stop the vertical feeding of the pine seedlings.

Moreover, the seedling stopping mechanism activated in the previous pre-planting process can be automatically released by operating a hydraulic control lever that raises the planting device when the machine turns around before starting the final planting process. This solves the conventional problem of not being able to plant all the rows in the final planting process due to forgetting to release the seedling stopping device before starting the final planting process.

Therefore, the seedling stopping mechanism can be activated with a simple operation, and at the same time, the activated seedling stopping mechanism can be automatically released by lifting and lowering the rice transplanting device when the machine is turned.
