It is a structure, and the powder and the granular material from 10 C of main tanks are drawn | feeded out from the main feed roll 20C.

  FIG. 6 shows a third embodiment. The sub tank 10F in this example is configured to be mounted inside the main tank 10E. That is, the sub tank 10F provided with the lid 51 is fixed with the fixing fastener 55 along the rear wall in the main tank 10E. The structure of the feeding device 11 is substantially the same as that of the first and second embodiments, and the powder / granular material from the sub tank 10F is provided from the sub feeding roll 20F provided below the sub tank 10F. It is the structure drawn out, and the powder and the granular material from the main tank 10E are drawn out from the main feed roll 20E. In particular, when configured as in the third embodiment, it is not necessary to form a recess for attaching a sub tank as in the first and second embodiments, and the configuration can be simplified. Further, the remaining amount sensor 56 is attached to the side wall of the sub tank 10F, and then the sub tank 10F can be positioned and fixed in the main tank 10E. Note that the remaining amount sensor 56 shown in the figure is provided with detection units on the front and back sides, the front-side detection unit 56a detects the presence or absence of powder or particulate matter in the main tank 10E, and the back-side detection unit 56b detects the sub tank 10F. It is the structure which detects the presence or absence of a powder and a granular material.

  FIG. 7 shows a method for detecting the remaining amount in the tanks 10A and 10B. As shown in FIG. 7, a transparent window 38B is provided vertically on the back of the sub-tanks 10B, 10B, and a transparent window 39B is provided on the inclined portion. It is configured. Further, on the main tank 10A side, a transparent window 38A is provided on the side surface of the main tank 10A, a transparent window 39A is provided on the inclined portion, and a scale is provided so that the amount of contents charged or the remaining amount can be confirmed.

  Further, in the tanks 10E and 10F in FIG. 6, the remaining amount sensor 56 is configured by an electrostatic capacity type detection means, and is configured as an internal capacity detection sensor capable of detecting the internal charging amount or the remaining amount, and the detection signal is transmitted to a control unit described later. 15 is output. The internal capacity detection sensor 56A is configured to detect the internal capacity of the main tank 10E, and the internal capacity detection sensor 56B is configured to detect the internal capacity of the sub tank 10F.

  Next, the control unit 15 of the granular spraying device 1 having the above configuration will be described. The control unit 15 includes a fertilizer controller 15A, a motor controller 15B, and a main machine controller 15C connected to each other (FIG. 8). Among them, the fertilizer controller 15A includes data necessary for fertilization and herbicide application, for example, the roll drive While inputting the motor rotation pulse of the motor 24, the selection information by the left and right boom spreading levers 48L and 48R, the drive information of the blower fan 12a, the remaining amount sensors 56a and 56b detection signals provided in the tank 10, etc., it is input to the motor controller 15B. A motor rotation output pulse signal, a motor rotation direction switching signal, etc. are output.

The machine controller 15C is configured to transmit the vehicle speed data from the means for detecting the vehicle speed to the fertilizer controller 15A.
Further, the fertilizer controller 15 </ b> A inputs information on switches disposed on the operation panel 55 including the liquid crystal display unit 54. In the vicinity of the liquid crystal display unit 54 on the operation panel 55, an automatic switch 57, a spray setting switch 58, increase / decrease switches 59U and 59D, and a cumulative reset switch 60 are arranged, and these operation switch signals are sent to the fertilizer controller 15A. It is an input configuration. The display content of the liquid crystal display unit 54 can display a fertilization amount set value, specific gravity value, fertilization cumulative value, input amount, and correction value, respectively, and is output so as to be sequentially switched and displayed when the display switch 61 is turned on.

  An example in which the display changeover switch 61 is operated to switch to the input amount display is shown in FIG. The liquid crystal display unit 54 is configured to display tank distinction, input amount, and work mode. That is, the main tank 10E is expressed as “large” and the sub tank 10F is expressed as “small”, and the input amount is displayed by converting the detection signals of the internal capacity detection sensors 56A and 56B.

Different control modes are incorporated in the fertilizer controller 15A. That is, an automatic mode, a manual mode, an emergency operation mode, and the like.
In the automatic mode, a motor rotation output pulse (roll drive motor rotation signal) is sent to the motor controller 15B that drives the roll of the feeding device 11 in accordance with the fertilizer application set value and the vehicle speed so that the fertilizer application amount per unit area becomes constant. Is output. The manual mode is configured to spray at a predetermined feed amount regardless of the vehicle speed, and is configured to change the mode every time the automatic switch 57 is turned on, and the automatic mode and the manual mode are displayed in FIG. is doing.

  The liquid crystal display unit 54 always displays the input amount together with the key switch ON of this unit, and switches to the remaining amount display when the operation of detecting the vehicle speed in the automatic mode is started. With this configuration, the display function of the initial input amount display and the remaining amount display is not required, and panel monitoring is facilitated. Similarly, the main tank 10E is indicated as “large” and the sub tank 10F is indicated as “small”, thereby simplifying the display. The selection of whether the main tank 10E or the sub tank 10F is selected is based on forward / reverse switching of the roll drive motor 25. That is, as described above, when the roll drive motor 25 is rotated forward, the main / sub feed rolls 20E, 20F corresponding to the main / sub tanks 10E, 10F are both fed out. This is because the rotation of the delivery roll 20 </ b> E or 20 </ b> F on the existing side is stopped and only a predetermined one-side roll is in the delivery state, and the use state can be selected by selecting and setting the rotation direction of the roll drive motor 25.

  The operation will be described with reference to the flowchart of FIG. 11. Before starting the fertilizer spraying operation, the automatic switch 57 is turned on while the machine is stopped to display the currently set fertilizer amount, and it is confirmed whether the fertilizer amount is suitable for the work. If they are different, the change is set by the increase switch 59U or the decrease switch 59D (S1).

  Then, the key switch 70 is turned on to start the engine. On the basis of the operation of the key switch 63, the liquid crystal display unit 54 is switched to the input amount display in the tank (S2). Based on the key switch 63 operation, the automatic mode is selected as the spraying mode unless the manual switch 71 is operated (S3), and a vehicle speed sensor signal is input. When it is determined that the state of the input signal of the vehicle speed sensor is that the vehicle speed is present and the body has started to move (S6), the liquid crystal display unit 54 is switched to the remaining amount display in the tank (S7). Here, which tank remaining amount of the main tank 10E or the sub tank 10F is used depends on the forward or reverse rotation of the feed roll motor 25, that is, the amount of spraying is large and the fertilizer in the main tank 10E is sprayed. When doing so, the detection result of the remaining amount sensor of the main tank 10E is adopted. On the other hand, when the spray amount is small and the medicine in the sub tank 10F is sprayed, the detection result of the remaining amount sensor in the sub tank 10F is employed.

Based on the determination result, the feeding motor 25 is linked to forward rotation or reverse rotation and controls rotation of the feeding roll 20E or 20F according to the vehicle speed (S8 to S11).
On the other hand, if the manual mode is selected by the manual switch 64 in the step 5, the process shifts to the manual mode (S12). Here, an input amount is displayed on the liquid crystal display unit 54 (S13), the work is started after the spray switch 72 is turned on, and the liquid crystal display is switched to a remaining amount display (S14, S15). Note that the forward and reverse rotations of the feeding roll motor 25 are selected depending on the set spray amount, as in the automatic mode, but the spray amount is constant and control by the vehicle speed is not performed (S16 to S19). ).

  When it is desired to finish the operation in either the automatic mode or the manual mode, when the spray switch 65 is turned off, the feeding roll motor 25 stops and the blower stops rotating (S20 to S22). Finally, the key switch 70 is turned off to stop the engine (S23).

  The remaining amount display on the liquid crystal display unit 54 in the automatic mode is executed after switching to the remaining amount display in step 7 (S7) until the key switch 63 is turned off (A in the figure). Therefore, since the remaining amount detection is continued while the aircraft is moving, the remaining amount can be reliably confirmed. Similarly, in the manual mode, even when the spraying switch 65 is turned off, the remaining amount is displayed and continues until the key switch 63 is turned off (B in the figure).
