  The conventional control controller has a configuration in which the automatic mode is not selected unless the automatic spray switch on this controller is pressed. Often, there was a problem that the spray setting and the actual spray amount differed greatly.

  An object of the present invention is to eliminate such problems.

In order to solve the above problems, the present invention has taken the following technical means.
That is, according to the present invention, the control pump switch (19) is provided on the control controller (20) or in the vicinity of the control controller (20), and the control pump (8) and the plurality of spray cocks (C1 to C3) are provided. ), The control pump switch (19) is turned on, and the control pump (8) is automatically driven based on the start of the machine to start the control work. It is a self-propelled control machine characterized by having a control means.

  The control pump switch (19) for driving the control pump (8) is pressed to enter the open state, and the spray cock (C1 to C3) is arbitrarily opened directly by the spray lever or hand. Then, when the aircraft is started, the control work is automatically started. Therefore, it is not necessary for the operator to switch between automatic and manual, and troubles caused by forgetting to select can be prevented.

  According to a second aspect of the present invention, in the first aspect, a manual mode selection button (29) is provided on the control controller (20) or in the vicinity of the control controller (20), and the manual mode selection button (29) The self-propelled pest control machine according to claim 1, wherein manual spraying is possible by an entering operation.

  When manual spraying is desired in the middle of automatic spraying, the manual mode can be switched by simply pressing the manual mode selection button (29), and the spraying pressure can be arbitrarily set to perform manual spraying. For example, it is possible to respond immediately depending on the state of the crop, such as by manually setting the spraying pressure to a high level only in an area where the occurrence of pests in the field is particularly severe.

  In short, according to the present invention of claim 1, when the spray cock (C1 to C3) is arbitrarily opened with the control pump switch (19) on the control controller (20) turned on, and the aircraft is started, the control is automatically performed. Since the work is started, it is not necessary for the operator to switch between automatic and manual operations one by one, and the problem that the spray setting and the actual spray amount differ greatly due to forgetting to select can be solved. In addition, since the chemical solution is automatically sprayed as the aircraft starts, forgetting to spray can be prevented.

  According to the second aspect of the present invention, while the effect of the first aspect is achieved, the manual mode selection button (29) is switched to the manual mode only when the manual spraying is desired. Work can be done manually. Therefore, for example, in an area where the occurrence of pests is particularly severe in crops in the field, it is possible to respond immediately depending on the state of the crop, such as by manually setting the spraying pressure at a high spraying pressure.

An embodiment of the invention will be described with reference to the drawings.
FIG. 1 and FIG. 2 show a riding type control machine. An engine E is mounted on the front part of the vehicle body 1, and the rotational power of the engine E is transmitted to a transmission in the mission case 2. The rotational power decelerated by the transmission is transmitted to the front wheels 3 and the rear wheels 4. A tank 5 containing a chemical solution is installed at the rear of the machine body. A driver's seat 6 is provided above the chemical solution tank 5 and a steering handle 7 is provided in front of the tank. The chemical solution in the chemical solution tank 5 is ejected from a nozzle 11 of a spray hose 10 provided in a spray boom 9 described later by a control pump 8.

Boom storage support frames 13 and 13 for storing and supporting the spreading boom are erected on both the left and right sides of the machine body, and are latched and held by a receiver 14.
Next, the structure of the spraying boom 9 will be described. The centering spraying boom (center boom) 9a substantially matches the lateral width of the fuselage, and is connected to the left and right sides of the left and right spraying booms (side booms). The lengths 9b and 9b are longer than that at the center. The side boom 9b is rotatably connected to the center center boom 9a, and is rotated upward by the side boom upper and lower cylinders 15 so as to be held in a housed state or spread substantially parallel to the ground. It can be rotated and supported in a working posture state.

  Next, a spray control device of a boom sprayer (chemical solution spray device) having a vehicle speed-linked spray system of a self-propelled control machine will be described. A control pump switch 19 for turning on / off the control controller 20, the controller panel 21 and the control pump 8, and spray cocks C1, C2, C3 of the booms 9a, 9b that can be manually opened and closed are installed on the side of the driver's seat 6. Is done. The spray cocks C1, C2, and C3 are opened and closed by operating the spray levers 12L, 12C, and 12R.

  Further, on the controller panel 21 provided with the control controller 20, display parts such as a spray setting 23, a pressure 24, a flow rate 25, a cumulative flow rate 26, and a form 27 are displayed on the left side of the display 22 at the upper center. The content of data displayed on the display is indicated by a triangular mark that is lit at the left end of the display 22. On the right side of the display 22, a display switching button 28 as a display switching means is provided. Below these, a manual mode selection button (manual button switch) 29 is provided, and this ON is indicated by a pilot lamp 30. Further, a spray setting button switch 31, increase / decrease button switches 32 and 33, a cumulative reset switch 34, and the like are arranged.

  The chemical liquid suction / discharge path of the spraying control device includes a low pressure water absorption path 35 extending from the chemical liquid tank 5 to the control pump 8 and a high pressure water discharge path 37 extending from the pump 8 through the flow rate control valve 36 to the spraying booms 9a and 9b. Connected by a hose or the like. The high-pressure water discharge path 37 is provided with a residual water return path 40 having a safety valve 38 for releasing a hydraulic pressure of a certain pressure or higher so that it can be returned to the tank 5. In addition, a stirring path 41 is communicated with the bottom of the tank 5, and a part of the chemical solution is constantly ejected and reduced into the tank to stir the chemical solution in the tank 5. In the high-pressure water discharge path 37 between the flow control valve 36 and the spray cocks C1, C2, C3 to the booms 9a, 9b, a pressure sensor 42 for detecting the hydraulic pressure and a first flow rate sensor 43 for detecting the flow rate are provided. Provided. Reference numeral 39 denotes an air chamber.

  In addition, a suction filter 44 is provided between the chemical liquid tank 5 and the pump 8 in the low-pressure water absorption path 35, and a flow rate in the water absorption path is detected between the suction filter 44 and the pump 8. A two-flow sensor 45 is provided.

  Then, the control controller 20 is turned on by pressing a control pump switch 19 that drives the control pump 8, the spray cocks C <b> 1 to C <b> 3 are opened by opening and closing the spray lever 12, and a traveling clutch is inserted to advance the machine body. An automatic spraying control means is provided in the form of a control program so that the microcomputer control work is automatically started. When manual spraying is desired during the automatic spraying control, the manual mode is switched by pressing the manual button 29, and the manual spraying operation can be easily performed by arbitrarily setting the spraying pressure.

  Further, in the self-propelled control machine in which the spraying operation is started in the automatic mode, the embodiment of FIG. 6 shows an example of the memory rotation of the nozzle constant, but corresponds to the type of nozzle in the internal memory of the display 22. An empty memory unit M (dispersion setting 5) that can set the nozzle constant is provided. In this empty memory, a new memory can be stored and set by the nozzle constant.

  In the embodiment shown in FIG. 7, a mode display function is provided in the display 22 portion of the controller panel 21. In a controller that prioritizes microcomputer control, the mode can be easily confirmed, and the mode setting and spraying status can be confirmed, so that the work stress can be greatly reduced. Further, as a means for operating this mode display function, it is configured so that it can be switched to the “setting mode” by operating the spray setting button switch 32 and the key switch (for engine start) on the control controller, and again when the key switch is turned OFF. If it is configured to switch to “spreading mode”, it is easy to make mode settings and to check the spraying status. Furthermore, after starting the work in the “spreading mode” display, the microcomputer detects the pulse input from the vehicle speed sensor within the set time, and at the same time the “spraying mode” is displayed in the “automatic mode”. It can be easily confirmed on the panel whether the microcomputer is properly controlled or not, and the work can be continued with peace of mind. When the manual button 29 is turned on and the manual mode is selected, the “manual mode” can be displayed on the display of the panel.

  When the pulse signal cannot be detected within the predetermined time during the operation in the automatic spraying mode, if the spraying error code is displayed at the same time, the vehicle speed sensor abnormality can be quickly notified to the operator. Thus, it will not be sprayed with a spraying amount different from the setting. Further, in the above configuration, the operator may not be able to recognize only by displaying the spray error code. Therefore, the flow control valve 36 may be closed simultaneously with the display of the spray error code so that the spray operation cannot be performed in the automatic mode. it can. However, it is desirable to enable spraying in the manual mode. In this case, the manual mode button 29 is turned on, and a predetermined spraying pressure is set for spraying.

  In the embodiment shown in FIG. 8, the microcomputer control controller that stores the automatic mode spraying control with different spraying forms has a spraying form display function in addition to the spraying mode display function. A vehicle speed-linked (automatic spraying) priority type microcomputer control machine is configured to always perform spraying in the automatic spraying mode when the manual spraying mode is not selected regardless of the spraying mode. According to this, since the selection of the automatic setting is not forgotten in any spraying form, spraying can be performed as prescribed. For example, a normal spraying mode that enables spraying from above the crop by the normal nozzle 11 as shown in FIG. 3 and a spraying and hanging from above the crop by the normal upper nozzle 11u as shown in FIG. For example, there is a vertical spraying form in which spraying from below by the lowering nozzle 11d can be performed simultaneously. In the case of standard spraying, “standard spraying” is displayed on the right side of the form 27 shown in FIG. 8, and in the case of vertical spraying, “upper and lower spraying” is also displayed on the right side of the form 27.

  In any of the above-described spraying forms, the automatic mode display can be prevented from being performed if there is a pulse input from the vehicle speed sensor after spraying is started. Since the operator can check the spraying mode each time, the spraying operation can be continued with confidence in the predetermined mode.

  In addition, when the vehicle speed pulse is interrupted during spraying in the automatic mode, the operator can check the spraying mode each time by displaying the spray error code. If an error due to a vehicle speed pulse occurs, the flow control valve 36 can be configured to automatically close. According to this, failure diagnosis can be performed quickly. Furthermore, in such a configuration, if the manual button 29 is turned on so that the spray mode can be continued by switching to the manual mode, the vehicle speed and pressure can be manually defined by the quick reference table even in the event of an automatic mode failure. By setting in accordance with the street, it becomes possible to spray a substantially prescribed amount.

  In the embodiment shown in FIG. 10, in the conventional spraying of 100 liters / 10a, the function of increasing / decreasing the spraying amount is conventionally installed and installed, but in the small amount spraying, the setting of the spraying amount of 25 liters is constant. In order to increase or decrease the counter-spattering amount, the indicator is set to the pressure position, and the amount of spraying is adjusted by correcting the pressure by pressing the increase / decrease button. According to this, there was a drawback that the capacity for changing the amount of spraying was different between conventional spraying and small-scale spraying, which was confusing. In order to solve this problem, in a controller with a small quantity spraying microcomputer, the increase / decrease for each liter is pushed by pressing the increase / decrease buttons 32, 33 with the basic setting of 25 liter / 10a spraying as the center. The amount can be changed. According to this, an easy-to-use control machine can be realized by making the spraying amount setting change procedure the same regardless of the type of nozzle.

  In addition, as shown in FIG. 10, it can implement also in the standard spraying form of the control machine which has a some automatic mode spraying form.
