And a discharge switch (3) for controlling the discharge of the application remaining amount by driving the supply roll (1), and the discharge switch (3) is set with the supply roll (1) set as a vehicle speed fixed value. During the spraying control by turning on the spraying switch (2), the discharging control by turning on the discharging switch (3) is controlled .

  Therefore, at the time of spraying work, the feeding switch 1 is driven by operating the spraying switch 2, and the applied agent stored in the hopper is fed to the spraying boom and sprayed onto the traveling farm scene or the like. The feeding roll 1 is interlocked according to the vehicle speed, and when the vehicle speed increases, the rotation of the feeding roll 1 also increases, and the application agent supply amount is increased so that the application agent is uniformly sprayed on the field scene or the like. . When the application agent remaining in the hopper after the spraying operation is taken out and discharged separately into a container or the like, a discharge switch 3 different from the spray switch 2 is operated. The delivery switch 1 is driven by the discharge switch 3 to draw out and discharge the remaining application agent to the hopper.

Further, in the spraying operation, when the spraying switch 2 is turned on, the feeding roll 1 is transmitted to the rotational speed corresponding to the vehicle speed, and the application agent is fed out and sprayed. When the application agent remaining in the hopper after the spraying operation is taken out and discharged, by turning on the discharge switch 3, the feeding roll 1 can be rotated and fed out as the vehicle speed fixed value regardless of the vehicle speed. Moreover, the discharge control by the discharge switch 3 is restrained during the spray control by turning on the spray switch 2, and cannot be discharged.

According to a second aspect of the present invention, there is provided a spraying switch (2) for controlling the spraying by driving the feeding roll (1) to a rotation according to the vehicle speed in a spraying device that sprays while applying the amount of application agent according to the vehicle speed. And a discharge switch (3) for controlling the discharge of the application remaining amount by driving the feeding roll (1), and by turning on the spray switch (2) during the discharge control by turning on the discharge switch (3).

  In the spraying device that sprays while applying the amount of the application agent according to the vehicle speed by the rotation of the feed roll 1, the operation device turns on the spray switch 30 that drives the feed roll 1 to turn on the buzzer after a predetermined time has elapsed. 41 is turned on to encourage spraying. When the spraying switch 30 is turned on, the minimum vehicle speed is set by determining the spraying width, the set application amount, the specific gravity of the application agent, etc., the initial rotation speed of the feeding roll 1 is determined and calculated, and the feeding roll 1 is rotated. Then pay out. In this way, it is possible to inform the driver of a certain time from when the feed roll 1 rotates to when the application agent is sprayed from the nozzle, and to start traveling at an appropriate timing. When the travel is started, the buzzer 41 is stopped. If traveling cannot be detected after a certain time has elapsed, the motor M rotation output is turned off.

  On the input side of the controller 40, there are a vehicle speed sensor 42 that detects the traveling vehicle speed of the vehicle body, a motor rotation sensor 43 that detects the rotation of the feeding motor M that rotates the feeding roll 1, and the residual fertilizer amount in the fertilizer hopper 2.

An output 46, opening / closing outputs 47L and 47R of the left and right spraying booms 6, a remaining amount lamp 48 for detecting the remaining amount of fertilizer, a buzzer 41, a monitor display 31 and the like are provided. The controller 40 includes a memory 49, a nonvolatile memory 50, and the like.

  In this case, the residual application agent discharge device includes a distribution switch 2 that controls the distribution by driving the supply roll 1 to rotate according to the vehicle speed in a distribution machine that distributes the application amount according to the vehicle speed. A discharge switch 3 is provided for driving the feed roll 1 to control the discharge of the remaining amount. At the time of spraying operation, the feeding roll 1 is driven by operating the spraying switch 2, and the applied agent stored in the hopper is fed to the spraying boom and sprayed onto the traveling farm scene or the like. The feeding roll 1 is interlocked according to the vehicle speed, and when the vehicle speed increases, the rotation of the feeding roll 1 also increases, and the application agent supply amount is increased, so that the application agent application to the field scene etc. is uniformly distributed to the desired set amount. To do. When the application agent remaining in the hopper after the spraying operation is taken out and discharged separately into a container or the like, a discharge switch 3 different from the spray switch 2 is operated. The delivery switch 1 is driven by the discharge switch 3 so that the remaining application agent is delivered to the hopper and separately taken out and discharged into a take-out container or the like.

  The discharge switch 3 is driven with the feeding roll 1 set as a vehicle speed fixed value, and during the spray control by the ON operation of the spray switch 2, the discharge control by turning on the discharge switch 3 is checked. Configure. In the spraying operation, when the spraying switch 2 is turned on, the feeding roll 1 is transmitted to the rotational speed corresponding to the vehicle speed, and the application agent is fed out and sprayed. When the application agent remaining in the hopper after the spraying operation is taken out and discharged, by turning on the discharge switch 3, the feeding roll 1 can be rotated and fed out as the vehicle speed fixed value regardless of the vehicle speed. Moreover, the discharge control by the discharge switch 3 is restrained during the spray control by turning on the spray switch 2, and cannot be discharged.

  Further, during the discharge control by turning on the discharge switch 3, the spray switch 2 is turned on so that the spray control can be performed. When the application agent remaining in the hopper is taken out and discharged after the application agent spraying operation, by turning on the discharge switch 3, the feeding roll 1 is driven to take out and discharge the application agent. During such discharge control, when performing the spraying operation of the hopper residual application agent, the spray control can be performed by turning on the spray switch 2. For this reason, by making a vehicle body drive | work to predetermined vehicle speed, the application agent paid out from the supply roll 1 can be sent to a spreading | diffusion boom, and can be spread | dispersed in a farm scene.

  Furthermore, at the time of discharge control by turning on the discharge switch 3, the set application amount is changed to change the number of rotations of the supply roll 1 and perform the discharge. In the spraying control, if the feeding amount of the application agent by the feeding roll 1 is set in advance as the set application amount, the shift control of the feeding roll 1 according to the vehicle speed is performed based on the set application amount, and the farm scene Perform uniform spraying work. Further, when the set application rate is changed during the discharge control by the discharge switch 3, the number of rotations of the supply roll 1 is changed, and the supply amount of the application agent can be changed and discharged.

  In place of the bellows hose 8 that switches and communicates with the collection container 7 for taking out and discharging the residual application agent of the hopper 2, a discharge shooter that branches the jet cylinder 5 and always communicates with the collection container 7 is provided. In addition, as a form in which the switching valve is provided, the switching valve is linked and switched by turning on the discharge switch 3, and the residual application agent fed by the feeding roll 1 is taken out and discharged to the collection container 7. it can.

Further, such a discharge switch 3 can be arranged at a position where it can be easily operated from outside the apparatus, such as near the installation position of the collection container 7 at the rear of the vehicle body, instead of the control panel 19.
The discharge switch 3 is a form of momentary without lock, in which the feeding roll 1 is driven when the switch is turned on, and the feeding roll 1 is stopped when the switch is turned on again. Since ON and OFF are repeated each time the pressing operation is performed, it is possible to prevent spraying in the discharge mode at the next spraying due to forgetting to turn off the switch at the end of discharging (flow step S1 in FIG. 5). When the discharge switch 3 is turned on, the discharge mode is entered and the rotation output of the feeding motor M is turned on. When the discharge switch is turned on during the discharge mode, the rotation output of the feeding motor M is turned off and the discharge mode is terminated.

  As described above, the spraying device sprays the application agent while feeding the feed roll 1 in conjunction with the vehicle speed, but when the discharge switch 3 is ON, the roll speed is set at the vehicle speed fixed value regardless of the presence or absence of the vehicle speed pulse. When the feeding roll 1 is driven by calculating the above, during the discharge mode when the discharge switch 3 is turned on, the input of the spray switch 30 is accepted and the mode is shifted to the normal spray mode (S2 in FIG. 5). . As described above, by switching to the spraying mode by turning on the spraying switch 30 during discharging (S3 in FIG. 5), it is possible to notify the driver of an erroneous operation. Further, when the input of the spraying switch 30 is not accepted, when the switch 30 is in a self-holding form (alternate), the spraying mode is shifted to the spraying mode at the end of the discharge mode, which can be prevented.

  When the discharge switch 3 is ON as described above, the discharge switch 1 is operated at the time of normal spraying by the spray switch 30 ON when the roll speed is calculated by driving the roll speed with a fixed vehicle speed regardless of the presence or absence of the vehicle speed pulse. 3 is not accepted (S6 in FIG. 6). When the discharge switch 3 is turned on, it is determined whether or not the spray switch 30 is turned on. When the spray switch 30 is turned on, the discharge process is restrained from being performed.

  When the discharge switch 3 is turned ON, the feeding roll 1 is driven under a fixed vehicle speed, and the remaining application agent is discharged and discharged to the hopper 2, but the set application amount is changed by the setting switch 32 (FIG. 7). S7) Thus, the number of rotations of the roll is calculated to change the number of rotations of the feeding roll 1, and the amount of feeding is changed. The feeding amount by the feeding roll 1 can be adjusted according to the situation at the time of discharging work, and workability can be improved.

  In the discharge control of the residual application agent by the discharge switch 3ON, when the fan switch 29 is OFF and the blower 4 is not rotating, the input of the discharge switch 3 is not accepted (S8 in FIG. 8). It is determined whether the fan switch 29 is ON or OFF when the discharge switch 3 is ON. If it is OFF, the mode is not shifted to the discharge mode. By accepting the ON operation of the discharge switch 3 only when the fan switch 29 is ON, clogging of the discharge application agent due to forgetting to put in the fan switch 29 is prevented.

  In the discharge mode with the discharge switch ON, the left and right one-side spray switches 36L and 36R for one-side spray are read, and when the switches 36L and 36R are ON, the motor M rotation output of the feeding roll 1 is turned on (FIG. 9 S9). In this way, by driving and stopping the corresponding feeding roll 1 by turning ON / OFF the one-side spray switches 36L and 36R, the one-side roll can be stopped according to the situation at the time of discharging work, and workability is improved. Can be improved.

  In the control mode in which the discharge switch 3 is not provided, when the spray switch 30 is turned ON, the rotation output of the feeding motor M is turned ON, and the buzzer 41 is turned ON intermittently after a predetermined time (S11 in FIG. 11). If the spray switch 30 changes from OFF to ON while the buzzer 41 is ON, it is determined that the discharge mode (S12 in FIG. 11) and the vehicle speed pulse is not detected (discharge control is often performed when the vehicle is stopped). The number of rotations of the roll is calculated with a fixed value, and the rotation output of the feeding motor M is continued. A simple control process can be performed by performing a discharge operation in a series of operation flows without providing the discharge switch 30.

  When spraying control is started by turning on the spraying switch 30 and the buzzer 41 is turned on after a predetermined time has elapsed, if the spraying switch 30 changes from OFF to ON during the ON operation of the buzzer 41, the vehicle speed is set as the discharge mode. The roll rotation speed is calculated with a fixed value, and the feeding roll 1 is driven.

  In FIG. 12, the left and right feeding rolls 1L, 1R are configured to be individually linked to the motors 50L, 50R, and the feeding roll 1L and the feeding roll 1R are integrated with the roll shafts 51L, 51R, the first feeding rolls 1La, 1Ra, The second feeding rolls 1Lb and 1Rb that are linked to the shafts 51L and 51R are provided only on the forward rotation side via a one-way clutch. Further, the third feeding rolls 1Lc and 1Rc having a short axial length are provided in series and used mainly when applying a small amount of herbicide or the like introduced into the narrow spaces 2Ls and 2Rs partitioned in the hoppers 2L and 2R. When the motors 50L and 50R are rotated forward by providing the motors 50L and 50R individually in such a manner that they can be rotated forward and backward individually, or by making the application agent input places different, a large amount is supplied from the first and second feeding rolls. A feeding amount can be secured, and a small amount feeding state of only the first feeding roll can be obtained when reversing. Further, the flow of the application agent can be appropriately made in the hopper. The third feeding rolls 1Lc and 1Rc are provided integrally with the shafts 51L and 51R, and are fed from the first and second feeding rolls 1La, 1Ra, 1Lb, and 1Rb according to the charging state to the charging hopper. Or whether to feed from the third feeding rolls 1Lc, 1Rc.

Accordingly, three types of feeding situations can be obtained by selecting the motor forward rotation state, the reverse rotation state, and the input position to the hopper, and this is called a roll type.
FIG. 13 and subsequent figures show examples of improvements in the case where the feeding rolls 1L and 1R are driven individually as described above. FIG. 13 shows a configuration in which the left and right feeding rolls 1L and 1R are interlocked by the drive motors 50L and 50R for the application agents from the left and right application hoppers 2L and 2R, respectively. In FIG. 13, in the calculation of the cumulative value of the applied agent feed amount, the left feed amount and the right feed amount are calculated each time the left and right feed rolls 1L and 1R make one rotation, and both are added. Thus, the accuracy of calculating the feeding amount can be improved.

  FIG. 14 shows that at the start of application of the application agent, in the initial roll setting, the roll rotation speed is calculated based on conditions such as the set fertilizer amount and specific gravity and the reference vehicle speed, and the roll type is set by comparing the value and the control range. In this configuration, it is possible to start work with an appropriate roll suitable for the set application amount at the start of spraying, and it is not necessary to switch rolls (setting the forward / reverse rotation of the motor) during application.

  FIG. 15 shows that when the types of the feeding rolls 1La and 1Lb or the feeding rolls 1Ra and 1Rb are determined by the motor 50L and 50R set rotation speed determination, the state where the set rotation speed exceeds the control range continues for a certain period of time. It is set as the structure which changes the kind of feeding roll 1La and 1Lb of both right and left simultaneous, or feeding roll 1Ra, 1Rb. Since the conventional set speed is calculated according to the set fertilizer amount and the vehicle speed, if the set pulse rate is incorrect or the vehicle speed pulse fluctuates due to an erroneous operation, the roll type may change and an unnecessary application stop section may occur. However, when configured as described above, the roll type can be changed when the set rotational speed changes and stability is determined, and the above-described drawbacks can be eliminated.

  In FIG. 16, when controlling the rotational speed by driving the left and right rolls individually, an abnormality is notified when the rotation of one of the motors cannot be detected, the output of the other motor is also stopped, and the abnormality content is displayed on the right. When the motor and the left motor are displayed separately, the rotation of the other motor is detected before the abnormality is displayed, and when both are abnormal, the display of the abnormality content is displayed separately from the individual abnormality. As a result, the contents of the abnormality can be distinguished by the left and right motors, and the abnormality of both the motors can be distinguished and displayed, and maintenance at the time of the abnormality is facilitated.

  In FIG. 17, when the rotation of one of the motors cannot be detected, an abnormality is notified, and when the output of the other motor is also stopped, the abnormality content is displayed separately for the right motor and the left motor. As a result, the contents of the abnormality can be distinguished and displayed by the left and right motors, facilitating maintenance.

  FIG. 18 shows that when one of the motors can no longer be detected, or when the set value is more than a certain value, an abnormality is reported and when the other motor is stopped, the one-side spray switch is turned off. For the motor on the side, the abnormality detection and determination are not performed. For this reason, by stopping the abnormality detection when the switch is turned off, it is possible to prevent the abnormality from being detected when the rotational speed decreases when the one-side switch is turned off.

  FIG. 19 shows that when the rotation speed of one motor is more than a certain value with respect to the set value, the output of the other motor is also stopped, and the abnormal contents are displayed separately for the right motor and the left motor. The rotation of the other motor is detected before the abnormality is displayed. If both are abnormal, the abnormality content is displayed separately from the individual abnormality. As a result, the abnormality content can be distinguished between the left and right motors, and both motor abnormalities can also be distinguished and displayed, facilitating maintenance when an abnormality occurs.

  In FIG. 20, when the rotation speed of one motor is more than a predetermined value with respect to the set value, when the output of the other motor is also stopped, the abnormality content is displayed separately for the right motor and the left motor. This makes it easy to perform maintenance when an abnormality occurs by distinguishing and displaying the abnormality content between the left and right motors.
