1 and 2 are a side view and a plan view of a riding rice transplanter (transplanting work machine) adopting a fluidized fertilizer switching device (indicator) of the present invention. A hood 4 having an engine therein is provided in front of a traveling machine body 3 having a rear wheel 2 below, and a driver's seat 7 having a seat 6 is provided behind the hood 4. A planting work machine (planting work machine) 9 in which a seedling stand 8 is installed obliquely behind the driver's seat 7 is provided via an elevating link mechanism 14 composed of an upper link 11 and a lower link 12. It is connected so that it can be raised and lowered and can be rolled.

As a result, the above-mentioned riding rice transplanter raises and lowers the planting work machine 9 through the elevating link mechanism 14 to ground the float 16 of the planting work machine 9 to the field and to plant a conventionally known seedling (not shown). By rotating the planted beak, the planted beak scrapes off the seedling from the seedling platform 8 and has a conventionally known structure for planting the seedling in the field. A driving force is input to the planting work machine 9 from the traveling machine body 3 side via the PTO shaft, and the driving force is input into the planter case 17 to which the planting beak is attached.

The present embodiment is a riding rice transplanter for six-row planting, in which three planter cases 17 are provided, and a float 16 is provided below each planter case 17. And the planted beak is planter case 17
The planted beaks, which are attached to both left and right sides of the planter case 17 and are provided on the left and right of each planter case 17, are rotationally driven by the driving force input to the corresponding planter case 17.

Further, in each of the planter cases 17, a planting clutch 18 for transmitting the driving force to the planting beak side so that the driving force can be freely connected and disconnected.
The planting clutch 18 can also stop the drive of the planting beak for each planter case 17, that is, the planting can be stopped every two rows. .

On the other hand, the riding rice transplanter is equipped with a fertilizer application device capable of performing fertilizer application in the field, and from the bottom surface of the float 16 so as to be inserted into the field when the float 16 touches the field. The projecting tubular fertilizer application (fertilizer application nozzle) 21 is adapted to apply the liquid fertilizer in the fertilizer tank 22 on the traveling machine body 3 side.

The fertilizer nozzle 21 is a planted seedling (planted article).
The same planter case 1 as the shallow layer nozzle 21a that is close to the left and right with respect to the left and right and applies fertilizer to a shallow position in the field
It is composed of two types, a deep-layer nozzle 21b for fertilizing the fertilizer at a deep position approximately in the middle of the adjacent planting strips which are planted by the left and right planting beaks driven by 7, and with respect to one planter case 17, Two shallow fertilizer application nozzles 21a arranged laterally close to the planted beak, and one deep fertilizer application nozzle 21b arranged between the planted beaks (between both shallow fertilizer application nozzles 21a) are provided. It is attached as a set.

As a result, with respect to the planting positions of the seedlings to be planted by the planting beaks provided on the right and left sides of the planter case 17, the left and right shallow fertilization nozzles 21a provided on the planter case 17 and the space between the fertilization nozzles 21a are provided. The deep-layer fertilizing nozzle 21b can correspondingly perform fertilizing.

The two differ in the vertical distance (height) from the float 17 to the end of the nozzle (tip which is the fertilizer discharge end), that is, the shallow-layer nozzle 21a is vertical from the float 17 to the end of the nozzle. The distance is relatively short and the depth nozzle 21b has a relatively long vertical distance from the float 17 to the end of the nozzle.

On the other hand, the fertilizer tank 22 is provided below the bonnet 4 on the front side of the traveling machine body 3, and is filled with fluid fertilizer (paste fertilizer) inside. And between the fertilizer tank 22 and each fertilizer application nozzle 21,
A pump (not shown) and a switching device (indicator) 23 for selectively switching between turning on and off of feeding fertilizer to each fertilizer application nozzle 21 (feeding and stopping feeding of fertilizer) are provided.

The fertilizer application apparatus is constructed as described above, and the paste fertilizer in the fertilizer tank 22 is once sent by the pump to the indicator 23. The indicator 23 selects the fertilizer nozzle 21 which allows the fertilizer to be sent out, The fertilizer is discharged from the fertilizer application nozzle 21 which is allowed to be fed, and the fertilizer is applied to the field.

The indicator 23 is arranged at the left and right center position of the airframe behind the seat 6, whereby the seat 6
Spaces S are formed on the left and right sides of the rear step 24 on the side of the space S, and the space S allows the operator to easily supply the seedlings to the seedling placing table 8.

As shown in FIGS. 3 to 6, the indicator 23 is constructed by arranging fertilizer feeding units 27 corresponding to the respective fertilizer application nozzles 21 in the outer cover 26 in parallel in the left-right direction. An input port 28 for fertilizer fed from the pump side is provided in front of each fertilizer feeding unit 27, and a fertilizer application nozzle 21 is provided behind each fertilizer feeding unit 27.
A valve 32 including a fertilizer discharge port 29 and a drain port 31 is provided.

That is, in the fertilizer feeding unit 27, when the fertilizer fed by the pump is input from the input port 28 and the fertilizer is applied by the fertilizer nozzle 21, the valve 3 is used.
When the fertilizer is discharged from the second discharge port 29 and the fertilizer application by the fertilizer application nozzle 21 is stopped, the fertilizer is discharged only from the drain port 31 of the valve 32. The fertilizer discharged from the drain port 31 is returned to the pump side by the return pipe.

The switching of the port for discharging the fertilizer is performed by the valve 32a, which has an arc shape in a side view inside the valve 32.
5, the discharge port 29 is blocked by the rotation of the valve as shown in FIG. 5, and the fertilizer feeding unit 27 is set in the streak state, whereby the fertilizer is blocked by the valve 32a and the arc-shaped valve 32a. The fertilizer is flown to the outside and discharged only from the drain port 31, and the fertilizer application by the fertilizer application nozzle 21 corresponding to the fertilizer feeding unit 27 is stopped (the fertilizer application is stopped).

Further, as shown in FIG. 6, the drain port 31 is closed by the rotation of the valve 32a, and the fertilizer feeding unit 27 is released from the stiffened state, so that the fertilizer flows outside the arc of the valve 32a and is discharged. The fertilizer is discharged from only the port 29, and fertilization is performed by the fertilizer application nozzle 21 corresponding to the fertilizer supply unit 27, that is, the stapling of the fertilizer application nozzle 21 is released.

A valve operating plate 33 is attached to the valve 32a at a side of the valve 32, and the valve operating plate 33 is rotated by an operating arm 34 projecting from the valve operating plate 33. By doing so, the valve 32a can be operated to selectively operate the fertilizer feeding unit 27 between the stapling state and the streak releasing state. That is, the valve operation plate 33 and the operation arm 34 constitute a fertilizer application tool for operating the switching of fertilizer delivery, and the fertilizer application tool is provided for each fertilization nozzle 21 (fertilization unit 27).

At this time, the diameter of the arc of the valve 32a is equal to that of the valve 32a.
It is set so that one of the drain port 31 and the discharge port 29 can be completely closed and the other can be completely opened without rotating 90 degrees, and when the fertilizer feeding unit 27 is in the stapling state (FIG. 5). Before the operation arm 34 becomes horizontal, the fertilizer is fed as shown in FIG. 6 by swinging the operation arm 34, which is installed so as to stand substantially vertically, backward by an angle smaller than 90 degrees. The unit 27 is switched to the release state of the bar stop.

On the other hand, in the present embodiment, the adjacent planting lines are planted by the planting beaks provided on the right and left sides of one planter case 17 as described above, and the deep fertilization is performed at the deep position of the field between the both planting lines. However, shallow fertilization is performed at the shallow layer position in the field on the side of both planting lines. Then, the fertilizing nozzles 21 for the adjacent strips (two shallow layer fertilizing nozzles 21a provided on one planter case 17 side and one deep layer nozzle 21)
The three fertilizer feeding units 27 corresponding to b) are provided adjacent to each other in the indicator 23. In the present embodiment, the fertilizer feeding units 27 for the deep layer nozzles 21b are provided on the left and right sides of the fertilizer feeding unit 27 for the shallow layer fertilizing nozzles 21a. The manure unit 27 is arranged adjacently.

The fertilizer unit 27 has a valve operation plate 33 having a hole 33a for connection.
One pin 36 is inserted into each hole 33a of the three valve operating plates 33 corresponding to the one planter case 17 to connect the three valve operating plates 33.

At this time, at least one (two in this embodiment) valve operating plate 33 is provided with a boss 37 concentric with the hole 33a, and two valve operating plates provided with the boss 37 are provided. 33 are connected by a pin 36 via a boss 37.

As a result, the pin 36, the hole 33a and the boss 37 are formed.
By the above, a linking mechanism that allows the fertilizer application nozzles 21 corresponding to the three connected valve operation plates 33 to operate in an interlocking manner is configured, and any one of the valve operation plates 33 (fertilizer operating tools) linked by the linking mechanism is configured. By performing the rocking operation, the three fertilizer application tools are simultaneously operated in conjunction with each other, and the fertilizer application nozzle 2 corresponding to each fertilizer feeding unit 27 is operated.
One bar stop can be operated at the same time.

Therefore, one end of the link rod 38 is rotatably connected to one of the three valve operation plates 33 connected to each other (the valve operation plate 33 for the deep nozzle 21b in this embodiment). At the same time, the other end of the link rod 38 is connected to a plate-shaped operation lever 41 supported on the bracket 39 side attached to the main body of the indicator 23 so as to be swingable back and forth.

As a result, the valve operating plate 33, to which the link rod 38 is connected, is caused to swing by the back and forth swinging of the operating lever 41, and at this time, the three valve operating plates 33 are linked via the pins 36 as described above. As a result, the three connected valve operating plates 33 are simultaneously swung by the swinging of the operating lever 41, the states of the corresponding three fertilizing units 27 are switched at the same time, and the shallow layers of the adjacent strips are simultaneously switched. Fertilization and deep fertilization between adjacent strips can be stopped with one touch at a time.

Since at least two valve operating plates 33 have the pins 36 inserted through the bosses 37, there is little reaction delay and twist of each valve operating plate 33 when the operating lever 41 is swung. The movements of the valve operation plates 33 do not become uneven, and there is little variation in the timing of switching the state of each fertilizer unit 27,
It is possible to prevent misalignment of the timing of stopping the fertilizer application and unevenness.

The operating lever 41 is used for the bracket 3
9 is projected from a lever guide 42 formed on the upper surface of the ferrule 9, and the tip side of the fertilizer unit 27 forms a grip portion 41a and faces forward. The whole is bent in a substantially V shape in a side view so as to be tilted and substantially parallel to the operation arm 34. Therefore, as shown in FIG. 5, when the fertilizer feeding unit 27 is switched to the streak state, the grip portion 41a is in the upright state.

With the above-described structure, the fertilizer application tools are centrally arranged behind (right behind) the seat 6, and the operation lever 41 and the fertilizer operation tool (the valve operation plate 33 and the operation arm 34) are provided. Are arranged close to each other with the front and rear operating directions, whereby the operator can feel the fertilizer by operating the operating lever 41 or the operating arm 34 by groping by extending the hand backward while sitting on the seat. The operation of stopping the streak of the strip can be easily performed by the operation of the bending and stretching motion of the arm, which is relatively easy to apply force.

In particular, since the grip portion 41a of the operation lever 41 and the operation arm 34 are substantially parallel to each other, the fertilizer feeding unit 27 is switched to the stapling state by moving the operation lever 41 or the grip portion 41a of the operation arm 34 forward. Since it can be performed by swinging to the side and standing up, the operator can easily perform the switching operation to the stapling state by putting the weight on the front side while holding the operation lever 41 or the operation arm 34. be able to.

Since one operating lever 41 is provided for each of the plurality (three) fertilizer feeding units 27, only three operating levers 41 are provided for each nine fertilizing nozzles 21 for planting six rows. The number of operation levers 41 is the fertilizer application nozzle 21.
The number is significantly smaller than the number (the number of operation arms 34), and it is easy to manually select the operation lever 41 corresponding to the fertilizer application line to be line-stopped, and the operability of the line-stop operation is high.

On the other hand, the fertilizer unit 2 in which the valve operating plate 33 is connected to the operating lever 41 as described above.
7 (fertilizer application nozzle 21) is connected to the shift lever of the planting clutch 18 in the planter case 17 provided with the planting beak via the wire 42, and the outer side of the wire 42 is connected to the main body of the indicator 23. It is attached to an outer receiver 43 provided at the bottom.

As a result, as described above, the fertilizing nozzle 2 corresponding to the planting beak whose drive and stop are operated by the swinging operation of the operating lever 41.
The stapling and stripping of the fertilizer application by 1 are automatically operated, that is, the operation lever 41 operates the operation part of the valve operation plate 33 connected by the pin 36 and the on / off operation of the planted beak. Also serves as a planting operation tool.

With the above structure, the operation of the planting beak for each planter case 17 is switched by the swinging operation of the operation lever 41, and at this time, the fertilizer streak is unnecessary when the planting beak is stopped. However, the fertilizer application is automatically started with one touch at the same time as the driving of the planted beak is stopped, or the required fertilization is automatically started with the start of the driving of the planted beak.

For this reason, the fertilizer application is automatically switched when the planted beak is turned on and off, and the seedlings planted by the planted beak are stopped by starting and stopping the driving of the planted beak by swinging the operating lever 41. It is possible to automatically switch between stopping and releasing the fertilization of the fertilization applied to the fertilization line corresponding to the planting position, and forgetting the operation of stopping and releasing the fertilization.

At this time, the operating lever 41 and the operating arm 34
Is swung in substantially the same direction in the same direction to stop the planting strip or fertilizer strip or release the stripping of the planting strip or fertilizer strip. It is possible to easily judge at a glance how the fertilizer-applied row is stopped, and to easily confirm the correspondence between the planting article and the fertilizer-applied article.

As shown in FIG. 7, the lever guide 42 includes a feed stop position 43 for positioning the operation lever 41 at a feed stop position P1 for switching the feed control unit 27 to a feed stop state, and a feed control unit 27. It is provided with a release position 44 which is positioned at the line release position P2 for switching to the line release state, and the positions 43 and 44 are connected by a movement guide 46.

The width T1 of the line stopping position 43 and the releasing position 44 is larger than the width T2 of the moving guide 46, and a step is formed between the moving guide 46 and the line fixing position 43 and the releasing position 44. Even when the operation lever 41 is inadvertently hooked by the foot due to the step, the operation lever 41 does not easily come off the streak stop position 43 and the release position 44, and the operation lever 41 is Positioning is reliably performed.

At the strut stop position 43, a protrusion 47 projecting into the streak stop position 43 is provided, and the wire 42 of the operating lever 41 is constantly urged to the streak release side via the wire 42. The urging force from the position prevents the line stop position 43 from coming off.

The pin 36 can be inserted into and removed from the hole 33a, and of the three valve operating plates 33,
Pin 3 for valve operation plate 33 that does not need to be linked
By removing from the connection by 6, the switching by the operation lever 41 of the fertilizer feeding unit 27 (fertilizer application nozzle 21) corresponding to the valve operation plate 33 can be released. Accordingly, by pulling out the pins 36 from all the valve operation plates 33, the stapling state and the streak releasing state of each fertilizer feeding unit 27 can be switched by the operating arm 34 separately.

In some cases, by removing one valve operating plate 33 from the connection of the pin 36, only the fertilizer feeding unit 27 corresponding to the valve operating plate 33 cannot be switched by the operating lever 41, so that the pin 36 is eventually replaced. Since it can be freely inserted into and removed from each valve operation plate 33, the combination of the valve operation plates 33 connected to each other can not only stop two fertilizer application lines but also
It is possible to carry out stapling of strips, stapling only deep-layer fertilization or shallow-layer fertilization, and further it can be used for stapling odd-numbered strips.

However, in the above embodiment, the pin 36
Since at least one of the valve operating plates 33 connected by means of the pin 36 is connected to the operating lever 41 via the link rod 38, only the pin 36 is connected to all of the three valve operating plates 33 corresponding to the operating lever 41. The connection cannot be released.

Therefore, the link rod 38 and the operating lever 4
1 or by releasing the connection with the valve operation plate 33, the connection between all three valve operation plates 33 and the operation lever 41 is released, and the fertilizer application is stopped (the fertilizer is discharged from the fertilizer nozzle 21). And, it can be configured to operate the stopper of the planting strip (driving the planting beak) completely independently.

That is, the link rod 38 and the pin 36 interlock the operation lever 41 and the operation arm 34 of the fertilizer application nozzle 21 corresponding to the planting position of the seedling planted by the planting beak operated by the operation lever 41. A linking mechanism that enables it is configured, and by attaching and detaching the link rod 38 and by inserting and removing the pin 36, the fertilizer nozzle 21 whose row stopper is operated in conjunction with the operation lever 41 is arbitrarily set between 0 and 3. can do.

On the other hand, as shown in FIGS. 4 and 8, each fertilizer feeding unit 27 is provided with a guide 46 that is lifted by the action of the diaphragm due to the increase of the internal pressure caused by the clogging of the fertilizer. When the fertilizer is clogged, 46 pushes up the lever 47 arranged above the guide 46 to operate the limit switch 48, and by operating this limit switch 48, the monitor of the driver's seat 7 is turned on and any one of the indicators 23 is displayed. Kano Fertilizer Unit 2
It is configured to notify that the fertilizer is clogged in 7.

At this time, between the guide 46 and the lever 47,
As shown in FIG. 8, the guide arm 49 is rotatably supported, and when the guide 46 is raised, the lever 47 is raised via the guide arm 49, and the guide arm 49 is swung upward at this time. The fertilizer feeding unit 27 that has caused the fertilizer clogging may be identified by the above.

At this time, as shown in FIG. 9, the guide arm 49 is composed of a plate having a step shape in a side view, and the rear of the upper surface is bent upward, and a hole 51 for inserting a fulcrum shaft is formed in the bent portion. The bent portion can be inserted between the brackets 52 of the fertilizer feeding unit 27 and can be rotatably supported via the fulcrum shaft.

A guide hole 53 is formed on the front surface of the outer cover 26 of the indicator 23 so as to guide the guide arm 49 in the left-right direction so that the guide arm 49 projects out of the indicator 23. The guide hole 53 can be used as a guide to swing up and down without lateral displacement.

[0054]

According to the structure of the present invention configured as described above, by connecting the planting operation tool and the fertilizer operation tool so that they can be interlocked with each other, the beak causes a predetermined beak to stop. Correspond to the planting line of the seedlings planted by the beak, which automatically stops the fertilization line (stops fertilization) corresponding to the planting line of the planting plant to be planted, or when the operation of a predetermined beak starts. The fertilizer application stops automatically.

In other words, the fertilizer application is automatically switched depending on whether the beak is turned on or off, and there is an effect that it is possible to prevent forgetting the operation of stopping and releasing the stop of fertilizer application. Further, by releasing the connection between the planting manipulator and the fertilizer applicator, it is possible to independently and independently stall the planting strip and the fertilizer strip.

At this time, the fertilizer application tools of the switching device are centrally arranged in the vicinity of the rear of the seat, and the planting operation tool and the fertilizer operation tool for controlling the operation of each beak are arranged in close proximity to each other, whereby Compared with the one provided for each fertilizer application, it is possible to easily operate the fertilizer operation tool by reaching out from the driver's seat.

Further, for example, when two beaks for two rows are stopped at the same time by one planting operation tool, a plurality of fertilizers corresponding to the planting positions of seedlings planted by both beaks are linked so as to be interlocked and operable. It is possible to stop fertilization for two rows (row stopping), and to stop the shallow layer fertilization to the shallow part of the field and the deep layer fertilization to the deep part of the field at the same time. In addition to this, since the connection mechanism can freely release the connection, it is possible to allow a line stop for each fertilizer application by releasing the connection.

Further, by configuring the planting manipulator and the fertilizer manipulator to operate up and down or back and forth, the operation from the seat is facilitated, and the planting manipulator of a predetermined beak and the beak There is also an advantage that it is possible to easily confirm the correspondence with the fertilizer application tool corresponding to the planting position of the seedling to be planted.
