Description

[Detailed description of the invention] The present invention provides a planting claw that plants the seedlings taken out from the seedling take-out port in the field as it circulates up and down, and closes the seedling take-out port to prevent the seedlings from falling. The present invention relates to a seedling planting device with a lid that can be opened and closed.

The above-mentioned seedling planting device is designed to suppress the accidental dropping of seedlings from the seedling outlet during non-seedling planting operations. Therefore, during the seedling planting operation, the seedlings held in the planting claws are prevented from unexpectedly detaching from the planting claws.

The structure of the present invention is characterized in that, in the above-mentioned seedling planting device, the lid body is positioned in an attitude substantially along the descending trajectory of the planting claw in the open state, and is also used as a seedling guide. do.

Next, the effects of the feature configuration of the present invention will be described.

In other words, the lid in the open state also serves as a seedling guide that follows the downward trajectory of the planting claws, and guides the seedlings held by the planting claws so that they do not come off the planting claws. It is possible to suppress the accidental detachment of the seedlings from the planting claws, and to perform even better seedling planting work, and the structure for this purpose is
As described above, it is possible to use a simple structure that also serves as a lid, and as a result, a seedling planting device that can be used more conveniently has been obtained.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIGS. 1 and 2, it is equipped with a pair of left and right front wheels 1, 1 that can be driven and rotated and whose direction can be changed, and a pair of left and right rear wheels 2, 2 that can be driven and rotated,
Engine 3 and transmission case 4, driver's seat 5
an inclined seedling platform 6 that moves back and forth horizontally at a constant stroke with six pine-shaped seedlings W placed side by side in the rear of the passenger vehicle body, which is located in front of the vehicle and at the front end of the vehicle; Six planting claws 7 take out one seedling from the lower end of each pine-shaped seedling W and plant it in the field as they circulate up and down, and are arranged side by side at appropriate intervals in the lateral direction. A seedling planting device 9 equipped with three floats 8 and the like is connected so as to be able to rise and fall via a pair of upper and lower lifting links 10a and 10b, and a hydraulic cylinder 11 for lifting and lowering the seedling planting device is connected to the lifting link 10a. , 10b are provided in a state where they can be vertically swung relative to the vehicle body, and six seedlings are planted sequentially as the vehicle advances, and in order to maintain a constant planting depth, and In order to avoid contact of the seedling planting device 9 with the ground when traveling on a headland or on a road, the seedling planting device 9 is configured to be able to be raised and lowered relative to the vehicle body.

To drive the seedling planting device 9, as shown in FIG. The input shaft 14 of the transmission case 13 for driving the device is interlocked and connected via a transmission shaft 15 with a universal joint that allows the seedling planting device 9 to move up and down. A planting clutch 16 that intermittents the drive of
is provided. A sliding shaft 17 for driving a seedling stand is attached to the transmission case 13 for driving the planting device.
are penetrated and supported so as to be slid at a constant stroke, and the claw drive transmission shaft 18 and three drive shafts 19 for each two adjacent planting claws 7 of the six planting claws 7 are interlocked. Three chains 20 are provided to be connected, and a movable clutch piece 22 is provided which freely rotatably supports an input sprocket 21 for driving the chain on the transmission shaft 18 and which engages and disengages each of the three input sprockets 21 by sliding. is spline-coupled to the transmission shaft 18 so as to be swingable, so that the driving of the six planting claws 7 and the seedling stand 6 can be switched on and off all at once.
Unnecessary driving of the pawl 17 can be stopped during work at the edge of the ridge.

As shown in FIGS. 3 to 5, a seedling take-out port 24 formed in a notch in a seedling sliding frame 23 horizontally disposed along the lower end of the seedling platform 6 is closed to prevent seedlings from falling. The lid body 25 is attached to a rotating horizontal shaft 26 and configured to be able to be opened and closed by swinging up and down, and each of the swinging type clutch levers 27 individually slides each of the movable clutch pieces 22. The lid body 25, which opens and closes the seedling outlet 24 corresponding to the two planting claws 7 whose drive is intermittent, is switched to the open state when the clutch is engaged, and to the closed state when the clutch is disengaged. An arm 26a fixed to the shaft 26 is interlocked with the arm 26a via a release wire 28, and is further provided with a spring 29 that closes and biases the lid 25. The seedling outlet 24 for the cover body 25
It is set to close at .

The lid body 25 is positioned in the open state in a position substantially following the descending trajectory of the planting claw 7, and is also used as a seedling guide, so that the seedlings held by the planting claw 7 are attached to the planting claw. It is designed to prevent unexpected falls from 7. Further, auxiliary seedling guides 30 are provided on both sides of the lid body 25 and also serve as a support frame for the horizontal shaft 26.

However, in the figure, 31a and 31b are bolts that regulate the opening/closing swing range of the lid 25, and 32 is a seedling pusher that protrudes toward the tip of the planting claw 7 when it reaches near the bottom dead center. .

In carrying out the present invention, it would be better to have the lid body 25 pivoted so that it can swing open and close, which would simplify the support structure. The support structure can be modified in various ways. Further, various modifications can be made, such as providing a dedicated operating tool for opening and closing the lid body 25.

In addition, when the driving of the plurality of planting claws 7 is divided into a plurality of groups and stopped individually as in the embodiment, the lid body 25 of the present invention prevents the planting claws 7 from being driven. This prevents the shaped seedlings W from falling into the seedling outlet 24 and being deformed and damaged as they are slid by the movement of the seedling platform 6, and also prevents the pine-shaped seedlings W from being deformed and damaged when the entire seedling planting device 9 is stopped. Although it is also possible to prevent the seedlings W from falling into the seedling take-out port 24, the present invention is a seedling planting device of a type that can only turn on and off the driving of all the plurality of planting claws 7 at once. It can be applied to various seedling planting devices.
