Description

  The present invention relates to a transplanter capable of issuing an alarm of shortage of seedling and fertilizer.

Conventionally equipped with a planting machine for planting seedlings and a fertilizer application mechanism for fertilizing fertilizers in the field, it reports seedling outage notification means for notifying seedlings out of seedlings for planting, and informs that fertilizers for fertilizer for fertilization have run out 2. Description of the Related Art A transplanter provided with a fertilizer shortage notification means is known (see, for example, Patent Document 1).
JP 2004-298022 A

  The transplanter is capable of lighting a center marker, and is configured to notify a worker (auxiliary) outside the traveling machine body of a seedling breakage or other abnormality by turning on the center marker. However, the center marker is provided at the center of the hood in front of the traveling machine body. For this reason, the range which can see lighting of a center marker is narrow, and there was a fault that it often overlooks a seedling out warning and a fertilizer out warning.

  The transplanter of the present invention for solving the above-mentioned problems is provided with a planting machine 8 for planting seedlings, and a fertilizer application mechanism for fertilizing fertilizers in a field, and a seedling for notifying that a seedling for planting has run out. In the transplanting machine provided with the cutting notification means and the fertilizer running notification means for reporting the fertilizer running out of the fertilizer for fertilization, the seedling cutting reporting means and the fertilizer running notification means are provided at both end portions of the planting work machine 8. The first feature is that the lamp is provided.

  Secondly, the winker lamps 16 are provided at both end portions of the planting work machine 8, and the winker lamps 16 are used both as winkers and lamps constituting the seedling outage notification means and the fertilizer outage notification means. As a lamp for notifying seedling or fertilizer, it is characterized by operating as a blinker at the time of non-planting work.

  Thirdly, an operation lever 22 for performing an operation on the planting work machine 8 side is provided in the vicinity of the steering handle 19 provided on the traveling machine body 1, and the planting unit 13 of the planting work machine 8 is driven by the operation lever 22. It is characterized in that it is possible to notify that the seedling has run out or the fertilizer has run out when the clutch can be turned on and off.

  Fourthly, it is characterized in that it is configured to notify separately whether the seedling runs out and the fertilizer runs out by changing the lighting pattern of the lamp.

  According to the structure of the present invention configured as described above, because the lamps provided at both end portions of the planting work machine notify that the seedling has run out or the fertilizer has run out, the area around the transplanter other than the driver in the driver's seat The worker (assistant) who is in can easily recognize that the seedlings and the fertilizer have run out. Thus, even if there is an assistant in a place where the seedling placement surface of the planting machine is not visible, the assistant can recognize the seedling or fertilizer shortage by the lamp. Thus, it is possible to start preparation work such as adding a work, which has an effect of improving work efficiency.

  In particular, the above lamps are provided at both ends of the planting machine, so there is a large range in which the lamps outside the traveling machine can be seen, and it is possible to easily recognize that the seedlings and fertilizer are out of place from various places. In addition, it is possible to prevent oversight of the seedling outage warning and the fertilizer outage warning.

  In addition, the winker lamps provided at both end portions of the planting machine are used as the winker and the lamps constituting the seedling outage notification means and the fertilizer outage notification means. When the non-planting operation is performed as a lamp for use, there is an advantage that it is not necessary to particularly provide a lamp that constitutes the seedling outage notification means and the fertilizer outage notification means by operating as a blinker.

  Usually, the winker is not used at the time of planting work in the field, and the lamp for notifying that the seedling has run out and the fertilizer has run out is unnecessary when traveling on the road. For this reason, the blinker lamp is used only as a lamp for notifying seedling or fertilizer shortage at the time of planting work, and is operated as a blinker only at the time of non-planting work, so that confusion caused by lighting of the blinker lamp can be prevented.

  In addition, notification of shortage of seedling or fertilizer may be performed only when the transplanter in the field is in a state in which seedlings can actually be planted. The state in which the seedling can be planted is a state in which an on / off operation of a clutch that drives the planting portion of the planting work machine by an operation lever that performs an operation on the planting work machine side provided at least near the steering handle is possible It is.

  Therefore, it is possible to efficiently notify that the seedling has run out or the fertilizer has run out by notifying that the seedling has run out or fertilizer has run out when the clutch can be turned on and off by the operation lever.

  The lamp itself can be used separately for cutting off seedlings and fertilizer, so that the lamps can be used separately by changing the lighting pattern of the lamps so that the seedlings and fertilizers run out separately. There is also an advantage that it can be easily distinguished from a break by different lighting of the lamp.

  1 to 3 are a front perspective view, a plan view, and a side view of a riding rice transplanter that is a transplanter adopting the present invention. The traveling body 1 of the riding rice transplanter includes front and rear wheels 2 and 3. A driver's seat 7 having a seat (seat) 6 is provided behind the hood 4 of the traveling machine body 1. Behind the traveling machine body 1, a planting work machine 8 is connected via an elevating link mechanism 9 so that it can be raised and lowered and rolled.

  The planting work machine 8 is provided with a seedling mounting table 11 on which a mat seedling for planting is placed. A plurality of planter cases 12 are attached to the frame side of the planting work machine 8 on the back surface (back surface) side of the seedling mount 11. The planter case 12 is provided with a planting unit 13 for scraping off seedlings from the mat seedlings placed on the seedling placing table 11 by rotational driving and planting them in a farm field.

  The planting work machine 8 is provided with a float 14 at a position below the planter case. The float 14 is attached to the planter case 12 side. On the left and right ends of the seedling table 11, blinker lamps 16 are provided. Markers 17 are attached to the left and right ends of the planting work machine 8.

  The elevating link mechanism 9 is raised and lowered by expansion and contraction of the hydraulic cylinder. That is, the planting work machine 8 moves up and down by the expansion and contraction of the hydraulic cylinder. The lift angle of the lift link mechanism 9, that is, the height position of the planting work machine 8 is configured to be detected by a lift angle potentiometer.

  A front operation panel 18 is provided in front of the seat 6. A steering handle 19 protrudes from the front operation panel 18. As shown in FIG. 4, the work implement operating lever 22 protrudes from one side (right in this embodiment) of the front operation panel 18 from the steering column 21.

  The work implement operation lever 22 is swingable up and down and back and forth. The raising / lowering operation of the planting work machine 8 can be performed by the vertical swing operation of the work machine operation lever 22. The marker 17 can be operated by swinging the work implement operating lever 22 back and forth. On the base end side of the work implement operation lever 22, a switch for detecting the front / rear and vertical swing operations of the work implement operation lever 22 is provided.

  By operating the work machine operation lever 22, the planting work machine 8 is lowered so that the float 14 is grounded on the farm scene, and the traveling machine body 1 is run in the field while the planting work machine 8 is being planted. Then, the planting part 13 that is rotationally driven as the traveling machine body 1 travels scrapes off the seedlings from the seedling mount 11 and plantes them in the field.

  The driving force to the planting machine 8 is transmitted through an unillustrated planting clutch. By setting the planting clutch in the engaged state, the driving force is transmitted to the planting work machine 8, and the planting operation as described above becomes possible. The planting clutch can be turned on and off by swinging up and down the work implement operating lever 22.

  With the planting operation, the seedlings for planting on the seedling mount 11 are gradually reduced. For this reason, a seedling detection sensor for detecting a shortage of seedling (whether or not seedling replenishment is necessary) is provided on the planting work machine 8 side.

  The posture of the marker 17 is switched between a work position that is lowered and extended to the side of the traveling machine body 1 as the planting work machine 8 is raised and lowered, and a non-work position that is raised and stored. The marker 17 draws a traveling reference line of the traveling machine body 1 on the farm scene at the work position. Marker automatic means for automatically switching the left and right markers 17 alternately between a working position and a non-working position is provided.

  By the automatic raising / lowering of the marker 17 by the marker automatic means (automatic switching between the working position and the non-working position), the order of the left and right markers that are fed out is automatically set each time the planting work machine 8 is raised and lowered once. Switched. On the other hand, the marker 17 on the opposite side of the marker 17 that is fed to the work position by the marker automatic means can be manually fed by the above-described swinging operation of the working machine operation lever 22. Since the feeding mechanism of the left and right markers 17 is known, a detailed description is omitted.

  Front steps 23 are provided on the left and right sides of the bonnet 4. Below the front step 23, a fertilizer tank 24 for storing fertilizer for fertilization is provided. If necessary, the fertilizer in the fertilizer tank 24 is fertilized on the field by a fertilizer nozzle (not shown) provided on the planting machine 8 side in association with the planting operation.

  An indicator 26 is provided between the fertilizer tank 24 and the fertilizer application nozzle. The indicator 26 is provided with a bar stop lever 28. The fertilizer nozzle can be selected by feeding the fertilizer by the stapling lever 28 to stop the fertilization. A fertilizer pump 27 that feeds the fertilizer from the fertilizer tank 24 toward the indicator 26 is provided below the seat 6.

  As described above, the fertilizer tank 24, the fertilizer nozzle, the indicator 26, the fertilizer pump 27, and the like constitute a fertilizer application apparatus. The fertilizer feeding device feeds the fertilizer from the fertilizer tank 24 to the indicator 26 by driving the fertilizer pump 27, and feeds the fertilizer to the fertilizer nozzle selected by the indicator 26 to perform fertilization.

  A driving force is transmitted to the fertilizer pump 27 through a fertilizer clutch so as to be freely turned on and off. The fertilization clutch on / off state (operation and non-operation of the fertilizer application) is detected by a fertilization clutch sensor. On the indicator 26 side, there is provided a streak sensor for detecting whether or not fertilization is stiffened. With the fertilization operation, the fertilizer in the fertilizer tank 24 gradually decreases. Therefore, a fertilizer detection sensor for detecting the remaining amount of fertilizer is provided on the fertilizer tank 24 side.

  The aforementioned front operation panel 18 is provided with an instrument panel (instrument panel) 29 in front of the steering post 21 as shown in FIG. On the side of the steering post 21, a winker operation lever 31, a planting preparation switch 32, and an automatic marker switch 33 are provided.

  The winker operation lever 31 can be swung left and right. The left turn signal lamp 16 is turned on by the leftward swing operation, and the right turn signal lamp 16 is turned on by the right swing operation. The planting preparation switch 32 is a switch that is entered (ON) during planting work.

  When the planting preparation switch 32 is turned off (OFF), the planting operation cannot be performed. The marker automatic switch 33 is a switch for selecting execution of automatic raising / lowering of the marker 17 by the marker automatic means described above.

  The instrument panel 29 is provided with a fertilizer warning light 34 indicating the remaining amount of fertilizer, a winker monitor 36 for displaying the operation of the left and right winkers 16, a seedling out warning light 37 for informing the above-mentioned seedling outage, and a fertilization stop. A stop warning lamp 38 for informing that the fertilizer is being applied, a fertilizer monitor 39 for notifying that fertilization is being performed, a planting monitor 41 for displaying that the planting operation is being performed, and the like are provided.

  The fertilizer warning lamp 34 is provided with a plurality of lamps between the F mark and the E mark. Each lamp notifies the driver of the driver's seat 7 of the remaining amount of fertilizer by sequentially turning off from F to E as the fertilizer decreases. The lamp 42 in the vicinity of the E mark is an empty lamp that prompts the replenishment of fertilizer, and notifies the driver of the driver's seat 7 that it is time to replenish the fertilizer by lighting.

  The blinker monitor 36 is configured such that when the left blinker lamp 16 is turned on, the left blinker monitor 36 blinks, and when the right blinker lamp 16 is turned on, the right blinker monitor 36 blinks. . However, the winker monitor 36 functions as a marker lamp for notifying which of the left and right markers 17 is lowered during the planting operation on the farm field by turning on the lower blinker monitor 36.

  The seedling-out warning lamp 37 indicates that it is time to replenish the mat seedlings to the seedling stage 11, the stapling warning lamp 38 indicates that fertilization is stopped, and the fertilizer monitor 39 performs fertilizing work. The planting monitor 41 notifies the driver of the driver's seat 7 that the planting operation is being performed by lighting each other. The marker automatic switch 33 is also used as an automatic marker monitor for notifying that the automatic raising / lowering of the marker 17 is executed when the marker automatic switch 33 is turned on (ON).

  The aforementioned hydraulic cylinder is controlled to extend and contract by a control valve (both not shown) in the control valve unit as in the prior art. The control valve is provided with a lifter cam (not shown) that controls the state of the control valve and the on / off of the planting clutch by rotation.

  The lifter cam is controlled by a lifter cam motor provided in the control valve unit. The rotation angle of the lifter cam is detected by a lifter cam potentiometer. The state of the control valve, that is, the state of the planting work machine 8 and the on / off state of the planting clutch are detected by the rotation angle of the lifter cam. Since the peripheral structure of the control valve is the same as the conventional structure, a detailed description is omitted.

  The control valve raises the hydraulic cylinder and raises the planting work machine 8 in an ascending position where pressure oil from the hydraulic pump is sent to the hydraulic cylinder side. The swing angle range of the lifter cam with the control valve as the raised position is referred to as the “lifted state” of the lifter cam.

  The control valve is in a lowered position for returning the pressure oil from the hydraulic cylinder to the oil tank, and enables the hydraulic cylinder to be contracted, and causes the planting work machine 8 to be lowered by its own weight. The swing angle range of the lifter cam with the control valve in the lowered position is referred to as the “lowered state” of the lifter cam.

  When the planting work machine 8 is lowered while the control valve is in the lowered position and the float 14 touches the field, the hydraulic cylinder can be automatically expanded and contracted so that the planting work machine 8 is moved up and down on the field scene. . This state in which the hydraulic cylinder can be automatically expanded and contracted is also realized by the “lowering state” of the lifter cam.

  When the lifter cam is further swung from the “lowered state”, the lifter cam enters the “planting state” in which the planting clutch is engaged and operated. In the “planting state” of the lifter cam, the control valve maintains a state in which the hydraulic cylinder can be automatically expanded and contracted so that the planting work machine 8 is moved up and down following the field scene.

  The control valve is a fixed position that stops the flow of pressure oil to the hydraulic cylinder and the flow of pressure oil from the hydraulic cylinder to the oil tank, fixes the position of the telescopic rod of the hydraulic cylinder, and increases the height of the planting work machine 8 Fix it. The swing angle range of the lifter cam with the control valve as a fixed position is referred to as a “fixed state” of the lifter cam.

  The automatic control, the motor rotation control, the various warning lights including the blinker lamp 16 and the lighting control of the various monitors as described above are executed by the microcomputer unit 43 constituting the control unit as shown in FIG. The

  On the input side of the microcomputer unit 43, the planting preparation switch 32, the fertilizer detection sensor 44, the seedling detection sensor 46, the streak sensor 47, the fertilizer clutch sensor 48, and the working machine operation lever 22 are swung upward. The raising operation switch 49 to detect, the lowering operation switch 51 to detect the downward swing of the work implement operating lever 22, the lifter cam potentiometer 52, the lift angle potentiometer 53, the automatic marker switch 33, and the work implement operating lever 22 to the front. A forward operation switch 54 that detects swing, a rear operation switch 56 that detects upward swing of the work implement operation lever 22, a right blinker switch 57 that detects swinging operation of the winker operation lever 31 to the right side, and winker operation A left blinker switch 58 that detects a swinging operation of the lever 31 to the left side is connected.

  On the output side of the microcomputer unit 43, the left and right blinker lamps 16, the fertilizer warning lamp 34, the seedling out warning lamp 37, the stapling warning lamp 38, the fertilizer monitor 39, the planting monitor 41, the marker automatic monitor (marker automatic monitor) In addition to the left and right blinker monitors 36, a lifter cam motor 59, a marker switching motor 61 for raising and lowering the left and right markers 17, and an alarm buzzer 62 are connected.

  Control of the raising / lowering of the planting work machine 8 and the on / off of the planting clutch by the above-described swinging operation of the work machine operating lever 22 is performed based on the work machine operating lever control program provided on the microcomputer unit 43 side. Functions as a work implement control lever control means, and is executed by controlling the operation of the lifter cam motor 59.

  As shown in FIG. 6, the work implement control lever control by the work implement control lever control program first checks the operation of the work implement control lever 22 based on the information from the raising operation switch 49 and the lowering operation switch 51 in step S1. To do.

  If there is a raising operation in step S 1, the process proceeds to step S 2, and the state of the lifter cam is checked based on information from the lifter cam potentiometer 52. If the lifter cam is in the “raised state” in step S2, the flow returns to the hydraulic pressure raising / lowering control flow as it is. Even if the working machine operation lever 22 is raised when the planting work machine 8 is raised, the raising of the planting work machine 8 is not particularly disturbed.

  If the lifter cam is in a state other than the “raised state” in step S2, the process proceeds to step S3, and the state of the lifter cam is checked again based on information from the lifter cam potentiometer 52. If the lifter cam is in the “fixed state” in step S3, the process proceeds to step S4 where the lifter cam 59 switches the lifter cam to the “up state” and returns to the hydraulic lift control flow.

  When the lifter cam is in the “fixed state”, that is, when the planting work machine 8 is fixed at a predetermined height position, when the work implement operating lever 22 is raised, the lifter cam is switched to the “raised state” and planted. The ascending work machine 8 starts to rise.

  If the lifter cam is other than “fixed state” in step S3, the process proceeds to step S5, and the state of the lifter cam is checked again based on the information from the lifter cam potentiometer 52. If the lifter cam is in the “planting state” in step S5, the process proceeds to step S6 where the lifter cam 59 switches the lifter cam to the “down state” and returns to the hydraulic lift control flow.

  When the lifter cam is in the “planting state”, that is, when the planting work machine 8 (float 14) is in contact with the field scene, when the work machine operation lever 22 is raised, the lifter cam is lowered. The planting machine 8 remains in the state where the float 14 is in contact with the field (following the planting machine 8 on the field scene), the planting clutch is disengaged and the planting machine 8 is planted. Attaching work stops.

  If the lifter cam is in the “lowered state” in step S5, the process proceeds to step S7 to check the lowered state of the planting work machine 8 based on information from the lift angle potentiometer 53. When the lowering of the planting work machine 8 is not stopped, the process proceeds to step S8, and the lifter cam motor 59 sets the lifter cam to the “fixed state” and returns to the hydraulic lift control flow. When the planting work machine 8 has stopped descending in step S7, the process proceeds to step S4.

  If the working machine operation lever 22 is raised while the planting work machine 8 is lowered, the lifter cam is switched to the “fixed state” and the height of the planting work machine 8 is fixed. Can be fixed at a height of When the work implement operating lever 22 is raised from a state where the planting work implement 8 is fixed at an arbitrary height, the lifter cam is switched to the “raised state”, and the planting work implement 8 starts to rise.

  If it is determined in step S1 that the work implement operation lever 22 is lowered, the process proceeds to step S9, and the state of the lifter cam is checked based on information from the lifter cam potentiometer 52. If the lifter cam is in the “raised state” in step S9, the process proceeds to step S10 where the lifter cam 59 switches the lifter cam to the “fixed state” and returns to the hydraulic lift control flow.

  When the work implement operating lever 22 is operated to be lowered while the planting work implement 8 is raised, the lifter cam is switched to the “fixed state”, and the height of the plantation work implement 8 is fixed. Thereby, the position of the planting work machine 8 can be fixed at an arbitrary height.

  If the lifter cam is not in the “raised state” in step S9, the process proceeds to step S11, and the state of the lifter cam is checked again based on the information from the lifter cam potentiometer 52. If the lifter cam is in the “fixed state” in step S11, the process proceeds to step S12 where the lifter cam motor 59 switches the lifter cam to the “lowered state” and returns to the hydraulic lift control flow.

  When the lifter cam 47 is in the “fixed state”, that is, when the planting work machine 8 is fixed at a predetermined height position, when the work implement operating lever 22 is lowered, the lifter cam is switched to the “lowered state”. The planting work machine 8 starts to descend.

  In step S11, if the lifter cam is other than the “fixed state”, the process proceeds to step S13, and the planting preparation switch 32 is checked for ON / OFF. When the planting preparation switch 32 is ON, the process proceeds to step S14, and the state of the lifter cam is checked based on information from the lifter cam potentiometer 52.

  If the lifter cam is in the “lowered state” in step S <b> 14, the process proceeds to step S <b> 15 to check the lowered state of the planting work machine 8 based on the information from the lift angle potentiometer 53.

  If the lowering of the planting work machine 8 is stopped in step S15, the process proceeds to step S16, where the lifter cam motor 59 sets the lifter cam to the “planting state” and returns to the hydraulic lift control flow. If the descent of the planting work machine 8 is not stopped in step S15, the process proceeds to step S17, where the “waiting state for engaging planting clutch” is set, and the flow returns to the hydraulic lift control flow.

  In the state where the planting preparation switch 32 is turned on, when the work implement operating lever 22 is operated while the planting work machine 8 is in contact with the field scene, the planting clutch is engaged and the planting work is performed. Can start.

  If the planting preparation switch 32 is OFF in step S13, and if the lifter cam is in the “planting state” in step S14, the flow returns to the hydraulic lift control flow. When the planting preparation switch 32 is OFF, the planting clutch is engaged and driven even if the work machine operating lever 22 is operated to be lowered while the planting work machine 8 is in contact with the farming scene. The planting work cannot be started. Moreover, even if the work machine operation lever is lowered during the planting operation, the planting operation is not particularly disturbed.

  If it is determined in step S1 that the work implement operation lever 22 has not been operated, the process proceeds to step S18, and it is checked whether or not the "planting clutch is in a waiting state". In the case of “waiting state for planting clutch”, the process proceeds to step S 19, and the descending state of the planting work machine 8 is checked based on the information from the lift angle potentiometer 53.

  When the lowering of the planting work machine 8 is stopped, the process proceeds to step S20, and the lifter cam motor 59 sets the lifter cam to the “planting state” and returns to the hydraulic lift control flow. If it is not in the “waiting state for engaging planting clutch” in step S18, or if the lowering of the planting work machine 8 is not stopped in step S19, the process returns to the hydraulic lifting control flow.

  If the work implement operating lever 22 is operated to be lowered while the planting implement 8 is continuously descending while the planting preparation switch 32 is in the ON state, the planting implement 8 can be operated without the operation of the work implement operating lever 22 thereafter. Comes into contact with the farming scene so as to be able to follow, the planting clutch is automatically engaged and driven, and planting work is started.

  By the work machine operation lever control shown above, the planting work machine 8 is raised and lowered according to the vertical operation of the work machine operation lever 22 as described above, and the on / off operation of the planting clutch is controlled. However, the planting clutch is not turned on unless the planting preparation switch 32 is turned on, and the planting clutch cannot be planted (planting operation) on the field.

  Since traveling on the field is different from traveling on the road, a winker is not required. For this reason, the microcomputer unit 43 indicates the direction of the marker 17 that is fed out to the working posture, with the winker monitor 36 in the instrument panel 29 when the riding rice transplanter is actually in a state where seedlings can be planted. It is configured to execute marker monitor display control that operates as a marker monitor. The blinker monitor 36 also serves as a marker monitor that displays the direction of the marker 17 that has been fed out.

  The monitor display control is executed by the microcomputer unit 43 based on a monitor display control program stored on the microcomputer unit 43 side. In order to plant seedlings, it is necessary to engage and disengage the planting clutch. The on / off operation of the planting clutch is possible when the planting preparation switch 32 is ON in the present embodiment as described above.

  That is, the state in which seedlings can be planted in the present embodiment is a state where the planting preparation switch 32 is ON. Therefore, in the marker monitor control, when the planting preparation switch 32 is ON, the left winker monitor 36 is turned on when the left marker 17 is extended, and the right winker monitor when the right marker 17 is extended. Is configured to light up.

  The above-mentioned seedling outage warning for informing and warning that it is time to replenish the mat seedlings to the seedling mount 11 and the fertilizer outage warning for informing and warning that it is the time for supplying fertilizer will be carried out at least in the field. This only needs to be done when planting is possible. The state in which seedlings can be planted by the riding rice transplanter is a state where the planting preparation switch 32 is ON in the present embodiment as described above.

  For this reason, when the planting preparation switch 32 is turned on, the microcomputer unit 43 uses a blinker lamp to separate the seedling outage warning lamp 37 and the fertilizer warning lamp 34 from the instrument panel 29. It is configured to perform an alarm control for executing an alarm of running out and fertilizer running out. The alarm control is executed by the microcomputer unit 43 based on an alarm control program stored on the microcomputer unit 43 side.

  In the alarm control based on the alarm control program, the state of the planting preparation switch 32 is first checked in step S1, as shown in FIG. If the planting preparation switch 32 is ON in step S1, the process proceeds to step S2 and the state of the seedling detection sensor 46 is checked. When the seedling detection sensor 46 detects that it is time to replenish the mat seedling to the seedling mount 11 in step S2, the process proceeds to step S3.

  In step S <b> 3, an alarm sound output set for warning that the buzzer 62 is out of seedling and a blinking output set for warning of the seedling out of the blinker lamp 16 are performed. From step S3, the process proceeds to step S4, where the state of the fertilizer detection sensor 44 is checked. When the seedling detection sensor 46 does not detect that the mat seedling replenishment stage 11 is being supplied to the seedling mount 11 in step S2 and is OFF, the process proceeds directly from step S2 to step S4.

  In step S4, when the fertilizer detection sensor 44 detects that it is time to replenish fertilizer and is ON, the process proceeds to step S5. In step S5, an alarm sound output set for warning the fertilizer running out to the buzzer 62 and a blinking output set for the winker lamp 16 warning of the fertilizer running out are performed. After step S5, the process returns. In step S4, when the fertilizer detection sensor 44 has not detected that it is a fertilizer replenishment time and is OFF, the process returns after step S4.

  The blinker lamp 16 and the buzzer 62 are turned on or sounded based on the output set set by the alarm control.

  As described above, the seedling shortage notifying means for notifying the seedling shortage is configured by the alarm control by the seedling detection sensor 46, the seedling shortage warning lamp 37, the blinker lamp 16, the buzzer 62, and the microcomputer unit 43. Further, the fertilizer detection sensor 44, the fertilizer warning lamp 34, the blinker lamp 16, the buzzer 62, and the alarm control by the microcomputer unit 43 constitute a fertilizer shortage notifying means for notifying the fertilizer shortage.

  When the planting preparation switch 32 is turned on by the seedling shortage notification means and the fertilizer shortage notification means, the seedling shortage and the fertilizer shortage are not only lit by the warning lights 37 and 34 in the instrument panel 29, but also by the buzzer 62 and the blinker lamp 16 An alarm is notified by flashing. Note that the lighting warning by the seedling out warning lamp 37 and the fertilizer warning lamp 34 in the instrument panel 29 is executed separately from the alarm control.

  If the blinker lamp 16 is configured not to blink and light as a blinker (corresponding to the operation of the blinker operation lever 31) when the planting preparation switch 32 is turned on, seedlings can be planted by this riding rice transplanter. In such a state, the blinker lamp 16 does not light as a blinker. On the other hand, when the planting preparation switch 32 is OFF during traveling on the road or the like, the blinker lamp 16 is not lit as a warning that the seedlings are running out or the fertilizer is running out.

  In this case, blinking lighting of the blinker lamp 16 in a state in which seedlings can be planted by the riding rice transplanter in the field serves as an alarm that the seedling has run out or fertilizer has run out, and the planting preparation switch 32 is OFF when traveling on the road or the like. The blinking lighting of the blinker lamp 16 in the case of being turned on becomes the original blinker lighting, and confusion due to the lighting of the blinker lamp 16 is avoided.

  However, the winker (the winker operating lever 31) is not operated in a state where seedlings can be planted by the riding rice transplanter. For this reason, in particular, the winker lamp 16 in a state in which seedlings can be planted by the riding rice transplanter in the field without canceling the blinking lighting as the winker when the planting preparation switch 32 is turned on. The blinking lighting of is a warning that the seedling or fertilizer has run out, and the blinking lighting of the blinker lamp 16 when the planting preparation switch 32 is OFF during road running or the like is distinguished from the original blinker lighting. can do.

  In other words, if the winker lamp 16 is used as a warning lamp for seedling and fertilizer shortage only in a state where seedlings can be planted by the riding rice transplanter, confusion caused by the lighting of the winker lamp 16 in any of the above cases. Can be avoided.

  As shown in FIG. 8 (a), the blinking output set for warning that the blinker lamp 16 is out of seedling has the same blinking phase of the left and right blinker lamps 16, and the right and left blinkers like a car hazard lamp. It is set in a pattern that causes the lamps 16 to blink simultaneously. As shown in FIG. 8B, the blinking output set for warning that the fertilizer is out of the blinker lamp 16 is a pattern in which the blinking phases of the left and right blinker lamps 16 are shifted by 180 degrees, and the left and right blinker lamps 16 are alternately blinked. Set by.

  As described above, the winker lamps 16 provided at both end portions of the planting work machine 8 are also used to notify that the seedling or the fertilizer has run out. For this reason, workers (auxiliaries) around the riding rice transplanter other than the driver of the driver's seat 7 can easily recognize that the seedling or the fertilizer has run out by blinking the blinker lamp 16.

  In particular, since the winker lamps 16 are provided at both end portions of the planting work machine 8, the range in which the winker lamps 16 outside the traveling machine body can be seen is large. Even if there is an assistant in a place where the mounting surface cannot be seen, the assistant can recognize the seedling runout and the fertilizer running out by over blinking the blinker lamp 16 without overlooking the seedling running out warning and the fertilizer running out alarm. .

  As a result, preparation work such as addition of seedlings and fertilizers can be started, and work efficiency is improved. The winker lamps 16 provided at both end portions of the planting work machine 8 are also used as lamps for informing the winker and the seedling outage and the fertilizer outage. Therefore, the lamps constituting the seedling outage informing means and the fertilizer outage informing means are provided. There is no need to provide it specially, and the cost can be reduced.

  As described above, the lighting pattern of the blinker lamp 16 is different between the seedling cut and the fertilizer cut, and the lamps for the seedling cut and the fertilizer cut are used by separately reporting the seedling cut and the fertilizer cut. In addition to being able to share itself, it is possible to easily distinguish between the seedling cut and the fertilizer cut by different lighting of the lamp.
