The external device is a personal computer (PC), a fixed computer such as a server, or a portable computer (mobile terminal) such as a smartphone or tablet.

A case where the set spray amount is set by the PC (referred to as a fixed terminal) 75 and the server 70, which are external devices, will be described with reference to FIG. The set spraying amount may be set by an internal device provided in the agricultural machine 1, for example, the display device 61, and is not limited.
The server 70 has a field storage unit 71 that stores a field map, a plan creation unit 72 that sets (creates) a spray plan including a set spray amount, and a plan storage unit 73 that stores a spray plan. The field storage unit 71 and the planned storage unit 73 are composed of a non-volatile memory or the like. The field storage unit 71 stores a plurality of field maps created in advance.

The planning screen M1 includes a field selection acquisition unit 100 for selecting a field, a field display unit 101 for displaying a field map, and a time input unit 102 for inputting a time. The field selection acquisition unit 100 displays a list of field maps stored in the field storage unit 71 as described above, and when one field map is selected from the list, the field display unit 101 displays the field. The field (selected field) selected by the selection acquisition unit 100 is displayed. When the time (month, day, time) is input in the time input unit 102, the time for spraying the sprayed material in the selected field is set.

<Control of spray amount>
As described above, the control device 60 can control the amount of spraying from the spraying unit 22 by controlling the spraying amount adjusting device (first spraying amount adjusting device 11L, second spraying amount adjusting device 11R). .. Further, the control device 60 can control the amount of air to be conveyed by controlling the transfer adjusting device (blower 201, adjusting device 202).

The control device 60 is a computer equipped with a CPU, a memory, and the like, and has a storage unit 85, a selection acquisition unit 86, and a setting unit 87, as shown in FIG. The storage unit 85 is a non-volatile memory or the like, and stores various information, programs, and the like used for controlling the amount of spraying. The selection acquisition unit 86 and the setting unit 87 are composed of electrical and electronic parts, programs, and the like provided in the control device 60. The selection acquisition unit 86 and the setting unit 87 execute operations related to control of the amount of spraying (operations for acquiring selections and operations for setting) based on information, programs, and the like stored in the storage unit 85.

In the embodiment shown in FIG. 8, the control device 60 provided separately from the display device 61 includes a storage unit 85, a selection acquisition unit 86, and a setting unit 87, but the display device 61 is a storage unit 85. It may be configured to include a selection acquisition unit 86 and a setting unit 87. In this case, the display device 61 functions as a control device having a storage unit 85, a selection acquisition unit 86, and a setting unit 87. Further, the display device 61 may be composed of a mobile terminal such as a smartphone or a tablet.

The storage unit 85 contains the rotation speed of the feeding roller 13R (first electric motor 14R) for adjusting the spraying amount of the first spraying amount adjusting device 11L (second spraying amount adjusting device 11R) and the rotation speed of the blower 201 per unit time. A plurality of specified lines that specify the relationship with the air volume are stored. FIG. 12 shows a plurality of specified lines L1 to L9 stored in the storage unit 85. The number of the plurality of specified lines may be two or more, but is preferably three or more, and more preferably five or more. In the case of this embodiment, the number of the plurality of specified lines is nine. The amount of air blown per unit time of the blower 201 can be adjusted by changing the area of the area where the air volume adjusting shutter (cover plate 203) provided in the suction port 201a of the blower 201a covers the suction port 201a.

The specified lines L1 to L9 are the rotation speeds (hereinafter referred to as the first electric motor 14R) of the feeding roller 13R (first electric motor 14R) for adjusting the spraying amount of the sprayed material discharged from the first spraying amount adjusting device 11L (second spraying amount adjusting device 11R). , "Spraying motor rotation speed") and the amount of air blown per unit time of the blower 201 (hereinafter referred to as "volume air volume"), the horizontal axis is the spraying motor rotation speed (rpm), and the vertical axis is the vertical axis. It is graphed as the amount of air blown (volume air volume) (m ³ / sec), and shows the relationship between the amount of sprayed material and the volume air volume.

That is, since the spraying amount of the sprayed material is determined by the spraying motor rotation speed, the graph showing the relationship between the spraying motor rotation speed and the volume air volume is also a graph showing the relationship between the spraying amount and the volume air volume of the sprayed material. Therefore, the specified lines L1 to L9 defined based on the relationship between the spraying motor rotation speed and the volumetric air volume define the relationship between the spraying amount and the volumetric air volume of the sprayed material discharged from the spraying amount adjusting devices 11L and 11R. It can be called a specified line.

The plurality of defined lines L1 to L9 are each defined based on the plurality of openings of the air volume adjusting shutter described above. One defined line corresponds to one opening degree of the air volume adjusting shutter. Therefore, the plurality of specified lines L1 to L9 correspond to a plurality (nine) openings of different air volume adjusting shutters, respectively.
For example, the specified line L1 is a graph of a function showing the relationship between the volumetric air volume and the spraying motor rotation speed when the opening degree of the covering plate 203 provided at the suction port 201a of the blower 201 is “A%”. be. The specified line L2 is a graph showing a function showing the relationship between the volume air volume and the spraying motor rotation speed when the opening degree of the covering plate 203 provided at the suction port 201a of the blower 201 is “B% (B> A)”. It was done. Similarly, when the opening degree of the specified line L3 is "C% (C>B)", when the opening degree of the specified line L4 is "D% (D>C)", the opening degree of the specified line L5 is When "E% (E>D)", the opening degree of the specified line L6 is "F% (F>E)", and the opening degree of the specified line L7 is "G% (G>F)". If there is, the specified line L8 has a volume air volume and a spraying motor rotation speed when the opening degree is "H% (H>G)" and the opening degree of the specified line L9 is "I% (I>H)". It is a graph of the function showing the relationship with.

For the plurality of specified lines L1 to L9, the opening degree of the air volume adjusting shutter (cover plate 203) is set in a plurality of stages, the change in the volume air volume is measured at each opening setting, and the volume air volume and the spraying are performed based on the measurement result. It can be obtained by calculating and graphing a function showing the relationship with the motor rotation speed (spraying amount of the sprayed material discharged from the first spraying amount adjusting device 11L (second spraying amount adjusting device 11R)). That is, the plurality of specified lines L1 to L9 can be derived by actual measurement. However, it is not necessary to derive all of the plurality of specified lines L1 to L9 by actual measurement, and some of the plurality of specified lines are derived by actual measurement as reference specified lines, and the remaining specified lines are derived by actual measurement. It may be derived by multiplying the function representing the above by the correction coefficient. Further, the plurality of specified lines L1 to L9 may be derived by a method other than actual measurement, for example, simulation.

When the air volume adjusting shutter is the covering plate 203, the air volume adjusting shutter (covering plate 203) adjusts the air volume (volume air volume) by changing the opening area of the suction port 201a of the blower 201. That is, the air volume adjusting shutter (covering plate 203) changes the opening area of the suction port 201a of the blower 201 by changing the opening degree, and changes the area of the region where the covering plate 203 covers the suction port 201a of the blower 201. By doing so, it is possible to control the air volume (the amount of the conveyed air) of the blower 201. Further, the air volume (conveyed air volume) of the blower 201 can be controlled by changing the area of the region where the covering plate 203 covers the suction port 201a while the rotation speed of the blower 201 is constant. Therefore, it is possible to control the air volume of the blower 201 without performing control for changing the rotation speed of the blower 201. This adjusts the air volume (volume air volume). In this case, the plurality of defined lines L1 to L9 are defined based on the plurality of openings of the air volume adjusting shutter. In this case, the "volume air volume" is the total amount of air transported through both the third pipe (first transport pipe) 29L and the fourth pipe (second transport pipe) 29R.

The selection acquisition unit 86 acquires one specified line selected from the plurality of specified lines L1 to L9 stored in the storage unit 85. The selection acquisition unit 86 displays on the display unit 61c a selection menu that enables an operation of selecting one specified line from the plurality of specified lines L1 to L9. The selection menu is displayed on the screen as a plurality of selection buttons when the display unit 61c is a touch panel. The operator can select one specified line by a method such as pressing a selection button from the selection menu displayed on the display unit 61c. The selection acquisition unit 86 acquires one selected specified line (information of a function representing the specified line).

The setting unit 87 sets the relationship between the spraying motor rotation speed and the volume air volume based on the specified line acquired by the selection acquisition unit 86. For example, when the specified line L1 is selected and acquired, the relationship between the spraying motor rotation speed and the volume air volume is set based on the specified line L1. Specifically, the opening degree of the air volume adjusting shutter (covering plate 203) is set to the opening degree when the specified line L1 is specified.

In the above-described embodiment, the amount of air to be conveyed is changed by adjusting the position of the covering plate 203 that covers the suction port 201a of the blower 201, but the output of the blower 201 (rotational speed of the blower fan) is adjusted. By doing so, the amount of air blown by the conveyed air may be adjusted.
In the above-described embodiment, the suction port 201a of the blower 201 is provided with an air volume adjusting shutter (cover plate 203), but the supply pipe 29 may be provided with an air volume adjusting shutter to adjust the air volume.

Hereinafter, an example of a method of adjusting the amount of spraying from the spraying unit 22 based on the control of the control device 60 will be described.
First, the selection acquisition unit 86 of the control device 60 displays a selection menu that enables an operation of selecting one specified line from the plurality of specified lines L1 to L9 on the display unit 61c of the display device 61. FIG. 13 shows an example of the display screen M2 displayed on the display unit 61c. A selection menu is displayed on the display screen M2. In FIG. 13, selection buttons E1 to E9 with numbers 1 to 9 are displayed as selection menus. Select buttons E1 to E9. Each corresponds to the specified lines L1 to L9. For example, when the selection button E1 is pressed, the specified line L1 is selected.

The operator performs an operation of temporarily selecting one specified line from a plurality of specified lines L1 to L9 based on the selection menu displayed by the selection acquisition unit 86 (first step). This temporary selection operation can be performed by pressing any of the selection buttons E1 to E9. The tentative selection is preferably made according to the type of sprayed material to be sprayed by the operator.
For example, if the sprayed object to be sprayed by the operator is one that is difficult to fly by the wind (for example, one with a large weight or specific gravity, one with a large particle size, etc.), the provision that the volume air volume is large with respect to the rotation speed of the spraying motor. Select a line (eg, any of L7 to L9). If the sprayed object to be sprayed by the operator is one that is easily blown by the wind (for example, one with a small weight or specific gravity, one with a small particle size, etc.), the specified line with a small volume air volume with respect to the rotation speed of the spraying motor (for example, one with a small particle size, etc.) For example, any one of L1 to L3) is selected. When the sprayed material to be sprayed by the operator is a standard one, a specified line (for example, one of L4 to L6) having a standard volume air volume with respect to the spraying motor rotation speed is selected.

When the worker tentatively selects one specified line, the selection acquisition unit 86 acquires one selected specified line. The setting unit 87 temporarily sets the relationship between the spraying motor rotation speed and the volume air volume based on the specified line temporarily selected and acquired by the selection acquisition unit 86 (second step). For example, when the specified line L5 is provisionally selected and acquired, the relationship between the spraying motor rotation speed and the volume air volume is temporarily set based on the specified line L5. Specifically, the opening degree of the air volume adjusting shutter (covering plate 203) is temporarily set to the opening degree when the specified line L5 is specified.

Next, the worker temporarily sprays the sprayed material by the spraying unit 22 based on the temporary setting, and measures the spraying amount (third step). This temporary spraying can be performed by the operator pressing the "spraying start" button E10 (see FIG. 13) displayed on the display unit 61c. The temporary setting can be canceled by pressing the "Cancel" button E11 (see FIG. 13) displayed on the display unit 61c.

Temporary spraying is performed for a certain period of time (for example, 30 seconds) by setting the spraying motor rotation speed to one specific rotation speed (for example, a standard rotation speed). The spraying motor rotation speed may be automatically set to a predetermined rotation speed, or may be selected by the operator from the display screen of the display unit 61c. When the "Start spraying" button is pressed, temporary spraying starts, and temporary spraying ends automatically after a certain period of time has elapsed.

The amount of spray is measured by attaching a collection bag for the spray to all or part of the spray ports 21L and 21R of the plurality of spray portions 22, collecting the spray, and measuring the weight of the collected spray. conduct. Even if the weight of the collected spray is measured by the weighing device provided in the agricultural machine 1 by the operator pressing the "weighing" button displayed on the display screen of the display unit 61c. Alternatively, the operator may measure using a weighing device.

When the weight measurement of the sprayed material sprayed by the temporary spraying is completed, the measured spraying amount by the temporary spraying is compared with the planned spraying amount (fourth step). The planned spray amount is the spray amount planned (planned) by the worker (for example, the standard fertilizer spray amount for crops). The planned spraying amount is input in advance by the operator and stored in the storage unit 85. The planned spraying amount is, for example, the set spraying amount Wn described above, but is not limited thereto. The control device 60 displays a screen on the display unit 61c that enables an operation of inputting the amount of spraying by temporary spraying. The operator can input the amount of temporary spraying from the screen displayed on the display unit 61c. When the measuring device provided in the agricultural machine 1 measures the amount of spraying by the temporary spraying, the control device 60 may be configured to read the measured value by the measuring device so that the input of the operator is unnecessary.

The control device 60 compares the amount of temporary spraying with the planned amount of spraying, and determines whether or not the difference between the two is within a predetermined amount stored in the storage unit 85 in advance. When the difference between the two exceeds a predetermined amount, the control device 60 determines whether the amount of temporary spraying is larger or smaller than the planned amount of spraying. This comparison and determination is preferably performed by the control device 60, but may be performed by an operator.

If the difference between the spraying amount by the temporary spraying and the planned spraying amount is within the predetermined amount, it means that the spraying desired by the operator is being performed, and the temporary setting is maintained. That is, the temporary setting is set as the final setting and the setting is completed. The setting end operation can be performed, for example, by the control device 60 displaying the "setting end" and "setting change" buttons on the display screen of the display unit 61c, and the operator pressing the "setting end" button. can.

When the difference between the amount of temporary spraying and the planned amount of spraying exceeds a predetermined amount, the operator presses the "change setting" button. Then, the selection acquisition unit 86 displays the selection menu on the display unit 61c, which enables the operation of selecting one specified line from the plurality of specified lines L1 to L9 again. The operator selects a specified line different from the tentatively selected specified line (for example, the specified line L5) from the selection menu displayed on the display unit 61c. For example, when the amount of temporary spraying is larger than the planned amount of spraying, one of the specified lines (specified lines L1 to L4) below the specified line L5 is selected. When the amount of temporary spraying is less than the planned amount of spraying, one of the specified lines (specified lines L5 to L9) above the specified line L5 is selected. Then, the first step to the fourth step are repeated until the difference between the amount of temporary spraying and the planned amount of spraying is within the predetermined amount, and the setting when the difference is within the predetermined amount is set as the final setting and the setting is completed. ..

By the above operation, the optimum specified line can be selected from a plurality of preset specified lines according to the type of the sprayed object to be sprayed by the operator, and the optimum specified line can be selected based on the selected specified line. A large amount of spray can be realized.
Next, among the plurality of spraying portions 22, the amount of spraying is sprayed from the spraying portion 22 on the base end side of the boom (first boom 18L, second boom 18R) and the spraying portion 22 on the tip end side. A method for making the amount of spraying uniform will be described.

In this method, after the above-mentioned first step and the second step, as the third step, after the above-mentioned temporary spraying is performed, the base of the boom (first boom 18L, second boom 18R) among the plurality of spraying portions 22 The amount of spraying from the spraying portion 22 on the end side and the amount of spraying sprayed from the spraying portion 22 on the tip side are measured. For the measurement of the amount of spraying, among the spraying ports 21L and 21R of the plurality of spraying portions 22, the spraying material collection bags are attached to the spraying port on the tip side and the spraying port on the base end side of the boom to collect and collect the sprayed material. This is done by measuring the weight of the sprayed material. Even if the weight of the collected spray is measured by the weighing device provided in the agricultural machine 1 by the operator pressing the "weighing" button displayed on the display screen of the display unit 61c. Alternatively, the operator may measure using a weighing device.

When the weight measurement of the sprayed material sprayed from the spraying portions 22 on the proximal end side and the distal end side is completed, as the fourth step, the difference between the spraying amount on the proximal end side and the spraying amount on the distal end side is calculated and calculated. It is determined whether the difference is within a predetermined value. The control device 60 displays a screen on the display unit 61c that enables an operation of inputting the amount of spraying on the proximal end side and the amount of spraying on the distal end side. The operator can input the amount of spraying on the base end side and the amount of spraying on the tip end side from the screen displayed on the display unit 61c. When the measuring device provided in the agricultural machine 1 measures the amount of spraying on the base end side and the amount of spraying on the tip end side, the control device 60 is configured to read the measured value by the measuring device, and the operator No input may be required. The control device 60 calculates the difference between the spraying amount on the proximal end side and the spraying amount on the distal end side, and determines whether the calculated difference is within a predetermined value stored in the storage unit 85 in advance. This comparison and determination is preferably performed by the control device 60, but may be performed by an operator.

If the difference between the spraying amount on the proximal end side and the spraying amount on the distal end side is within a predetermined value, the provisional setting is maintained. That is, the temporary setting is set as the final setting and the setting is completed. The setting end operation can be performed, for example, by the control device 60 displaying the "setting end" and "setting change" buttons on the display screen of the display unit 61c, and the operator pressing the "setting end" button. can.
When the difference between the spraying amount on the base end side and the spraying amount on the tip end side exceeds a predetermined value, the operator presses the "change setting" button. Then, the selection acquisition unit 86 displays the selection menu on the display unit 61c, which enables the operation of selecting one specified line from the plurality of specified lines L1 to L9 again. The operator selects a specified line different from the tentatively selected specified line (for example, the specified line L5) from the selection menu displayed on the display unit 61c. When the amount of spraying on the base end side is smaller than the amount of spraying on the tip end side, one of the specified lines (specified lines L1 to L4) below the specified line L5 is selected. When the amount of spraying on the base end side is larger than the amount of spraying on the tip end side, one of the specified lines (specified lines L5 to L9) above the specified line L5 is selected. Then, the first step to the fourth step are repeated until the difference between the spraying amount on the proximal end side and the spraying amount on the distal end side is within a predetermined predetermined value, and the setting when the difference is within the predetermined amount is set. Finish the setting as the final setting.

As a result, the optimum specified line can be selected from a plurality of preset specified lines in order to realize uniform spraying according to the type of sprayed material selected by the operator, and the selected line is selected. It is possible to realize spraying that equalizes the spraying amount to be sprayed from a plurality of spraying portions based on a specified line.
<Shape of operation switch>
A plurality of screens are displayed on the display unit 61c of the display device 61 in response to the operation. FIG. 14 shows an example of the display screen M3 displayed on the display unit 61c. The display screen M3 is an example of a screen that can be displayed after the farm work support application software (hereinafter, also referred to as “application”) stored in the storage unit 85 is started. The agricultural work support application is an application that supports agricultural work by the agricultural machine 1 by displaying the running and work (spraying) states of the agricultural machine 1. That is, the display device 61 operates as a support device for supporting farm work after the application is started.

As shown in FIG. 14, an operation switch 110 for performing an operation of spraying the sprayed material from the spraying unit 22 is displayed on the upper right of the display screen M3. FIG. 15 shows only the operation switch 110 extracted from the display screen M3.
The operation switch 110 has a first operation unit 111, a second operation unit 112, a third operation unit 113, and a fourth operation unit 114. The first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114 are operated by pressing or contact (hereinafter, referred to as "pressing or the like"). Specifically, the first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114 are displayed on the touch panel constituting the display unit 61c. The operator can operate each operation unit by pressing the first operation unit 111, the second operation unit 112, the third operation unit 113, the fourth operation unit 114, etc. displayed on the touch panel.

The first operation unit 111 is an operation unit for performing an operation of spraying the sprayed material from the first spraying unit 221. The second operation unit 112 is an operation unit for performing an operation of spraying the sprayed material from the second spraying unit 222. The third operation unit 113 is an operation unit for performing an operation of spraying the sprayed material from the first spraying unit 221 and the second spraying unit 222. The fourth operation unit 114 is an operation unit for performing an operation for stopping the spraying of the sprayed material from the first spraying unit 221 and the second spraying unit 222.

As shown in FIG. 15, the first operation unit 111 has a display meaning “left”. The second operation unit 112 has a display meaning "right". The third operation unit 113 has a display indicating "both". The fourth operation unit 114 has a display meaning "stop". The color of a part or the whole of the fourth operation unit 114 can be made different from the color of other operation units so as to be conspicuous and to respond to an emergency.

The operation switch 110 changes the color of the operation unit in the state where the operation based on the operation (spraying or stopping) is executed to a color different from the color of the operation unit in the state where the operation is not performed. For example, in a state where the sprayed material is sprayed from the first spraying unit 221 by the operation of the first operating unit 111, the color of the first operating unit 111 changes to a color different from the color of the other operating units. When the spraying of the sprayed material is stopped by the operation of the fourth operation unit 114, the color of the fourth operation unit 114 changes to a color different from the color of the other operation units.

When the operation of the first operation unit 111 is performed, the control device 60 transmits a control signal to the first electric motor 14L. The first electric motor 14L sprinkles the sprayed material from the first spraying unit 221 by rotating the feeding roller 13L of the spraying discharge mechanism 13 by the control signal output from the control device 60. When the spray discharge mechanism 13 is a shutter type mechanism, the first electric motor 14L sprays the sprayed material from the first spraying unit 221 by opening the shutter according to the control signal output from the control device 60.

When the operation of the second operation unit 112 is performed, the control device 60 transmits a control signal to the first electric motor 14R. The first electric motor 14R sprinkles the sprayed material from the second spraying portion 222 by rotating the feeding roller 13R of the spraying discharge mechanism 13 by the control signal output from the control device 60. When the spray discharge mechanism 13 is a shutter type mechanism, the first electric motor 14R sprays the sprayed material from the second spraying unit 222 by opening the shutter according to the control signal output from the control device 60.

When the operation of the third operation unit 113 is performed, the control device 60 transmits a control signal to the first electric motors 14L and 14R. The first electric motors 14L and 14R rotate the feeding rollers 13L and 13R of the spraying discharge mechanism 13 by the control signal output from the control device 60, so that the sprayed material is sprayed from the first spraying portion 221 and the second spraying portion 222. Is sprayed. When the spray discharge mechanism 13 is a shutter type mechanism, the first electric motors 14L and 14R open the shutter according to the control signal output from the control device 60, whereby the first spray unit 221 and the second spray unit 221 and the second spray unit Spray the spray from 222.

When the operation of the fourth operation unit 114 is performed, the control device 60 transmits a control signal to the first electric motors 14L and 14R. The first electric motors 14L and 14R stop the rotation of the feeding rollers 13L and 13R of the spraying discharge mechanism 13 by the control signal output from the control device 60, thereby causing the first spraying unit 221 and the second spraying unit 222 to stop rotating. Stop spraying the spray. When the spray discharge mechanism 13 is a shutter type mechanism, the first electric motors 14L and 14R close the shutter by the control signal output from the control device 60, whereby the first spray unit 221 and the second spray unit 221 and the second spray unit Stop spraying the spray from 222.

When the operation of the fourth operation unit 114 is performed, the control device 60 has the first spraying unit 221 and the second spraying unit 222 when the sprayed material is sprayed from the first spraying unit 221 and the second spraying unit 222. When the spraying material is stopped from the first spraying unit 221 only, the spraying material is stopped from the first spraying unit 221 and the sprayed material is sprayed only from the second spraying unit 222. Is sprayed, the spraying of the sprayed material from the second spraying unit 222 is stopped.

Next, the arrangement of the first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114 will be described. In the following description of the display unit 61c, the upper, lower, left, and right directions are the directions when viewed from the direction perpendicular to the screen of the display unit 61c.
As shown in FIG. 15, the first operation unit 111 is arranged on the left portion of the operation switch 110 on the side (left side) corresponding to the first boom 18L. The second operation unit 112 is arranged on the right side of the operation switch 110 on the side (right side) corresponding to the second boom 18R. The fourth operation unit 114 is arranged between the first operation unit 111 and the second operation unit 112. The third operation unit 113 is arranged below the fourth operation unit 114. That is, the first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114 are arranged in a T shape as a whole.

As shown in FIG. 1, in the agricultural machine 1, the first boom 18L extends to the left from the machine body 2, and the second boom 18R extends to the right from the machine body 2. That is, the agricultural machine 1 has a T-shape when viewed from the front in a state where the boom is extended to the left and right (that is, in a state of being sprayed). Therefore, the operation switch 110, which is T-shaped as a whole, is reminiscent of the front view shape of the agricultural machine 1. The first spraying portion 221 is provided on the first boom 18L, and the second spraying portion 222 is provided on the second boom 18R. Therefore, the first operation unit 111 arranged on the left side of the operation switch 110 is reminiscent of the first spraying unit 221 and the second operation unit 112 arranged on the right side of the operation switch 110 is reminiscent of the second spraying unit 222. Let me.

Further, in the agricultural machine 1, the spraying direction of the sprayed material from the first spraying portion 221 and the second spraying portion 222 is downward. Since the third operation unit 113 arranged at the lower part of the operation switch 110 is arranged in the direction (downward) corresponding to the spraying direction of the sprayed object, it reminds us of a state in which the sprayed object is sprayed. On the other hand, since the fourth operation unit 114 arranged above the third operation unit 113 is arranged in the direction opposite to the spraying direction (upward), it reminds us of a state in which the spraying of the sprayed material is stopped.

As described above, since the arrangement of each operation unit reminds us of the position and spraying direction of the spraying unit, the operator can use the first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114. It is possible to intuitively grasp the function of each operation unit from the arrangement of. Therefore, it is possible to quickly operate each operation unit without making a mistake and to perform the spraying work accurately.
FIG. 16 is a diagram showing a modified form of the operation switch 110.

As for the operation switch 110 of this modified form, the first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114 as a whole are the same as the operation switch 110 of the embodiment shown in FIG. It is arranged in a T shape. The operation switch 110 of this modified form is different from the operation switch 110 of the embodiment shown in FIG. 15 in that the arrangement of the third operation unit 113 and the fourth operation unit 114 is reversed. That is, in the operation switch 110 of the modified form, the third operation unit 113 is arranged between the first operation unit 111 and the second operation unit 112, and the fourth operation unit 114 is arranged below the third operation unit 113. ing.

As shown in FIGS. 15 and 16, in the operation switch 110 according to the present invention, the operation unit of either the third operation unit 113 or the fourth operation unit 114 is the first operation unit 111 and the second operation unit 112. The operation unit of either the third operation unit 113 or the fourth operation unit 114 is arranged below the one operation unit.
FIG. 17 is a diagram showing another modification of the operation switch 110.

The operation switch 110 of this other modification is different from the operation switch 110 of the embodiment shown in FIG. 15 in the first operation unit 111, the second operation unit 112, the third operation unit 113, and the fourth operation unit 114. In addition, it has a fifth operation unit 115 and a sixth operation unit 116. The operation switch 110 of this other modification is used when the first boom 18L and the second boom 18R are configured to be expandable and contractible.

The fifth operation unit 115 is an operation unit for performing an operation of expanding and contracting the first boom 18L. The sixth operation unit 116 is an operation unit for performing an operation of expanding and contracting the second boom 18R.
When the operation of the fifth operation unit 115 is performed, the control device 60 transmits a control signal to the actuator that operates the first boom 18L. The actuator expands and contracts the first boom 18L by the control signal output from the control device 60. Specifically, when the first boom 18L is shortened, it is extended, and when the first boom 18L is extended, it is shortened.

When the operation of the sixth operation unit 116 is performed, the control device 60 transmits a control signal to the actuator that operates the second boom 18R. The actuator expands and contracts the second boom 18R by the control signal output from the control device 60. Specifically, when the second boom 18R is shortened, it is extended, and when the second boom 18R is extended, it is shortened.
As shown in FIG. 17, the fifth operation unit 115 is arranged on the left side of the first operation unit 111. The sixth operation unit 116 is arranged on the right side of the second operation unit 112. That is, the fifth operation unit 115 is arranged on the leftmost side of the operation switch 110, and the sixth operation unit 116 is arranged on the rightmost side of the operation switch 110. The first operation unit 111, the second operation unit 112, the third operation unit 113, the fourth operation unit 114, the fifth operation unit 115, and the sixth operation unit 116 are arranged in a T shape as a whole.

As described above, in the agricultural machine 1, the first boom 18L extends to the left from the machine body 2, and the second boom 18R extends to the right from the machine body 2. Therefore, the operation switch 110, which is T-shaped as a whole, is reminiscent of the front view shape of the agricultural machine 1. The extension direction of the first boom 18L is to the left, and the extension direction of the second boom 18R is to the right. Therefore, the fifth operation unit 115 arranged on the leftmost side of the operation switch 110 is reminiscent of the extension of the first boom 18L, and the sixth operation unit 116 arranged on the rightmost side of the operation switch 110 is the extension of the second boom 18R. Reminds me of.

In this way, the arrangement of the fifth operation unit 115 and the sixth operation unit 116 reminds us of the extension of the first boom 18L and the second boom 18R, so that the operator can use the fifth operation unit 115 and the sixth operation unit 116. The function of each operation unit can be grasped intuitively from the arrangement. Therefore, it is possible to operate each operation unit quickly without making a mistake and to expand and contract the boom accurately.
The operation switch 110 of another modified form shown in FIG. 17 may be used when the first boom 18L and the second boom 18R are configured to be bendable (undulating). In this case, the fifth operation unit 115 is an operation unit for performing an operation for raising and lowering the first boom 18L. The sixth operation unit 116 is an operation unit for performing an operation for raising and lowering the second boom 18R.

<Display of work status (spraying status) of agricultural machinery>
As shown in FIG. 14, on the display screen M3 of the display unit 61c of the display device 61, a figure showing the spraying status from the spraying unit 22 is displayed. The display unit 61c includes a field display unit 190, a vehicle body display unit 191 and a spray unit display unit 192. The control unit 61a of the display device 61 can acquire the position of the traveling vehicle body 8 from the positioning device 63 and controls the display unit 61c (field display unit 190, vehicle body display unit 191 and spray unit display unit 192).

The field display unit 190 is a portion that displays a graphic Z1 that virtually represents a field (field or the like) on which the traveling vehicle body 8 travels. The figure Z1 representing the field on which the traveling vehicle body 8 travels includes a horizontal line Z11 and a grid (mesh) composed of horizontal lines Z12 and vertical lines Z13. In order to express the depth (three-dimensional effect) of the field, the distance between adjacent vertical lines Z13 becomes narrower as it approaches the horizontal line Z11.

The field display unit 190 shows a vehicle body display unit 191. The vehicle body display unit 191 virtually shows the traveling vehicle body 8 by the figure Z2 representing the position of the traveling vehicle body 8. The figure Z2 representing the position of the traveling vehicle body 8 is displayed as a triangular figure sharpened toward the traveling direction of the traveling vehicle body 8, and is superimposed on the figure Z2 representing the position of the traveling vehicle body 8 to represent the traveling direction. The arrow Y1 is displayed. The display position of the vehicle body display unit 191 with respect to the field display unit 190 is fixed. Further, the center position of the vehicle body display unit 191 is the current position of the traveling vehicle body 8 on the field display unit 190.

Therefore, when the traveling vehicle body 8 is actually traveled, the display position of the traveling vehicle body 8 of the field display unit 190 remains fixed, and the field display is accompanied by the change in the position of the traveling vehicle body 8 detected by the positioning device 63. The virtual field (field image) shown in part 190 scrolls and rotates.
The spraying unit display unit 192 is a portion that displays the figure Z3 representing the spraying unit 22. The spraying unit display unit 192 has a first spraying unit display unit 192A and a second spraying unit display unit 192B. The first spraying unit display unit 192A displays the figure Z31 representing the first spraying unit 221 on the left portion on the side corresponding to the first boom 18L. The second spraying unit display unit 192B displays the figure Z32 representing the second spraying unit 222 on the right portion on the side corresponding to the second boom 18R.

The figure Z3 representing the spraying portion 22 is displayed on the side corresponding to the direction of the spraying portion 22 with respect to the traveling vehicle body 8. Specifically, since the first spraying portion 221 is provided on the first boom 18L extending to the left with respect to the traveling vehicle body 8, the figure Z31 representing the first spraying portion 221 is on the left side of the vehicle body display unit 191. It is displayed to extend. Since the second spraying portion 222 is provided on the second boom 18R extending to the right with respect to the traveling vehicle body 8, the figure Z32 representing the second spraying portion 222 is displayed so as to extend to the right of the vehicle body display unit 191. ing. Thereby, the operator can intuitively grasp the meaning of the figures Z31 and Z32 representing the first spraying portion 221 and the second spraying portion 222.

The figure Z31 representing the first spraying portion 221 includes a plurality of small figures Z31a arranged at intervals from the center in the width direction of the figure Z2 representing the position of the traveling vehicle body 8. The figure Z32 representing the second spraying portion 222 includes a plurality of small figures Z32a arranged at intervals from the center in the width direction of the figure Z2 representing the position of the traveling vehicle body 8. These small figures Z31a and Z32a are figures reminiscent of a plurality of spraying portions 22 provided on the first boom 18L and a plurality of spraying portions 22 provided on the second boom 18R. In the case of this embodiment, the small figures Z31a and Z32a are circular, but may have other shapes (squares or the like). Further, the figure Z31 representing the first spraying portion 221 is a rod-shaped figure extending to the left from the center in the width direction of the figure Z2 representing the position of the traveling vehicle body 8, and the figure Z32 representing the second spraying portion 222 is the position of the traveling vehicle body 8. It may be a bar-shaped figure extending to the right from the center of the figure Z2 in the width direction. Further, the figure Z31 representing the first spraying portion 221 and the figure Z32 representing the second spraying portion 222 may be formed by arranging small figures such as circles along the lower part of the rod-shaped figure. Further, the figure Z3 representing the spraying portion 22 may be a part of the figure Z2 representing the position of the traveling vehicle body 8. Further, the figure Z2 representing the position of the traveling vehicle body 8 may also serve as the figure Z3 representing the spraying portion 22.

The spraying unit display unit 192 is a portion that displays a spraying state in which the sprayed material is sprayed from the spraying unit 22 and a stopped state in which the spraying material is stopped from the spraying unit 22. The control unit 61a displays on the spraying unit display unit 192 a spraying state in which the sprayed material is sprayed from the spraying unit 22 and a stopped state in which the spraying material is stopped from the spraying unit 22. Let me.
The first spraying unit display unit 192A displays that when the first operating unit 111 is operated, it is in a spraying state in which the sprayed material is sprayed from the first spraying unit 221. The second spraying unit display unit 192B displays that when the second operating unit 112 is operated, it is in a spraying state in which the sprayed material is sprayed from the second spraying unit 222. Further, when the third operation unit 113 is operated, it is displayed that the first spraying unit display unit 192A is in the spraying state in which the sprayed material is sprayed from the first spraying unit 221, and the second spraying unit display unit 192B is displayed. Indicates that is in a spraying state in which the sprayed material is sprayed from the second spraying unit 222. When the fourth operation unit 114 is operated, the display of the spraying state changes to the display of the stopped state. In this way, the operation of the operation switch 110 and the display of the spraying unit display unit 192 are linked.

The control unit 61a causes the first spraying unit display unit 192A to display the spraying state and the stopped state of the first spraying unit 221 in different display modes. Therefore, the first spraying unit display unit 192A displays the spraying state and the stopped state of the first spraying unit 221 in different display forms. The control unit 61a causes the second spraying unit display unit 192B to display the spraying state and the stopped state of the second spraying unit 222 in different display modes. Therefore, the second spraying unit display unit 192B displays the spraying state and the stopped state of the second spraying unit 222 in different display forms.

The control unit 61a causes the spraying unit display unit 192 to display the display color in the spraying state and the display color in the stopped state so as to be different. Therefore, in the spraying unit display unit 192, the display color in the spraying state and the display color in the stopped state are different. FIG. 14 shows the display of the spraying unit display unit 192 when the first spraying unit 221 is in the spraying state and the second spraying unit 222 is in the stopped state. In this case, the display color of the first spraying unit display unit 192A and the display color of the second spraying unit display unit 192B are different.

For example, the spraying unit display unit 192 has a yellow display color when it is in the spraying state and a black display color when it is in the stopped state. As described above, it is preferable that the brightness or saturation of the display color in the sprayed state is higher than the brightness or saturation of the display color in the stopped state. As a result, the operator can intuitively grasp whether the spraying unit 22 is in the spraying state or the stopped state from the display color of the spraying unit display unit 192.

As shown in FIG. 14, the display unit 61c includes a locus display unit 193. The locus display unit 193 is a portion that superimposes and displays the figure Z4 representing the spraying locus of the sprayed object by the spraying unit 22 on the field display unit 190. The control unit 61a causes the locus display unit 193 to display the figure Z4 representing the spray locus along the movement locus of the spray unit 22 in the spray state so as to overlap with the field display unit 190. The movement locus of the spraying unit 22 can be calculated based on the position of the traveling vehicle body 8 acquired from the positioning device 63 and the positional relationship between the traveling vehicle body 8 and the spraying unit 22 stored in advance.

The locus display unit 193 has a first locus display unit 193A and a second locus display unit 193B. The first locus display unit 193A displays a graphic Z41 representing a spray locus by the first spray unit 221 on the left portion on the side corresponding to the first boom 18L. The second locus display unit 193B displays a graphic Z42 showing a spray locus by the second spray unit 222 on the right portion on the side corresponding to the second boom 18R.

The control unit 61a causes the first locus display unit 193A to display the graphic Z41 representing the spray locus along the movement locus of the first spray unit 221 in the spray state so as to overlap with the field display unit 190. The control unit 61a causes the second locus display unit 193B to display the graphic Z42 representing the spray locus along the movement locus of the second spray unit 222 in the spray state so as to overlap with the field display unit 190.
The figure Z4 representing the spraying locus of the sprayed object by the spraying portion 22 is a band-shaped figure so as to extend to the side opposite to the traveling vehicle body 8 (lower side of the display screen M3) with respect to the figure Z3 representing the spraying portion 22. Is displayed. The figure Z41 representing the spraying locus by the first spraying unit 221 extends to the opposite side (lower side of the display screen M3) from the figure Z2 representing the position of the traveling vehicle body 8 with respect to the figure Z31 representing the first spraying unit 221. Is displayed. The figure Z41 showing the spraying locus by the first spraying unit 221 is displayed with the same width as the display width of the figure Z31 representing the first spraying unit 221. The figure Z42 showing the spraying locus by the second spraying portion 222 extends to the opposite side (lower side of the display screen M3) from the figure Z2 representing the position of the traveling vehicle body 8 with respect to the figure Z32 representing the second spraying portion 222. Is displayed. The figure Z42 showing the spraying locus by the second spraying unit 222 is displayed with the same width as the display width of the figure Z32 representing the second spraying unit 222.

In this way, the locus display unit 193 displays the graphic Z4 representing the spraying locus of the sprayed material by the spraying unit 22 on top of the field display unit 190, so that the sprayed material is sprayed on any part of the field. Can be grasped on the display screen M3. Further, the graphic Z31 representing the first spraying unit 221 and the graphic Z32 representing the spraying locus by the second spraying unit 222 are displayed on the field display unit 190, so that the sprayed material is sprayed by the first spraying unit 221. The area where the sprayed material was sprayed, the area where the sprayed material was sprayed by the second spraying unit 222, and the area where the sprayed material was sprayed by the first spraying unit 221 and the second spraying unit 222 are grasped on the display screen M3. can do.

On the display screen M3 shown in FIG. 14, only the first region RG1 in which only the figure Z41 showing the spraying locus by the first spraying unit 221 is displayed and the figure Z42 showing the spraying locus by the second spraying unit 222 are displayed. There are two regions RG2 and a third region RG3 in which the figures Z41 and Z42 showing the spraying locus by the first spraying unit 221 and the second spraying unit 222 are displayed. By looking at this display screen M3, the operator sprays only the first spraying portion 221 in the first region RG1, and sprays only by the second spraying portion 222 in the second region RG2, and the third region RG2. In RG3, it can be grasped that the spraying was performed by the first spraying section 221 and the second spraying section 222.

In FIG. 14, the figures (Z1 to Z4) showing the spraying status from the spraying unit 22 and the operation switch 110 for performing the operation of spraying the sprayed material from the spraying unit are displayed on the same display screen M3. It may be configured to be displayed on different display screens.
Further, in the present invention, the spraying unit display unit 192 may be configured to have the function of the operation switch 110. For example, the figure Z31 displayed on the first spraying unit display unit 192A is pressed to start or stop the spraying from the first spraying unit 221, and the figure Z32 displayed on the second spraying unit display unit 192B is executed. Can be configured to start or stop spraying from the second spraying unit 222 by pressing or the like. In this case, the first spraying unit display unit 192A has the functions of the first operation unit 111 and the fourth operation unit 114, and the second spraying unit display unit 192B has the functions of the second operation unit 112 and the fourth operation unit 114. Have.

The control unit 61a can store the spray locus in the storage unit 61b. Specifically, when the start or stop of spraying from the first spraying section 221 is executed, when the start or stop of spraying from the second spraying section 222 is executed, the first spraying section 221 and the second spraying section 221 are executed. The spraying information of the start and stop of spraying of the unit 222 and the position information of the spraying based on the signal from the positioning satellite are stored in the storage unit 61b as the history information of the spraying trajectory. The stored history information of the spray locus can be displayed on the display device 61 or an external device (fixed terminal 75 or the like). As a result, even when the first spraying section 221 or the second spraying section 222 is stopped for some reason, such as avoiding falling objects in the field, the actual spraying status can be confirmed.

The configuration of the display device 61 described above can be applied not only to the agricultural machine 1 provided with the spraying unit 22 for spraying the sprayed material, but also to the agricultural machine 1 performing agricultural work other than spraying. That is, the configuration of the display device 61 described above can be applied to the agricultural machine 1 provided with the agricultural work unit that performs agricultural work not limited to the spraying work.
Therefore, "spraying" in the above explanation (explanation of "display of work status of agricultural machinery") can be read as "work" or "agricultural work". Therefore, the "spraying section", "first spraying section", and "second spraying section" can be read as "agricultural work section", "first agricultural work section", and "second agricultural work section", respectively. The first agricultural work unit works on the left side or the left side of the traveling vehicle body 8, and the second agricultural work unit works on the right part or the right side of the traveling vehicle body. In addition, the "spraying unit display unit", "first spraying unit display unit", and "second spraying unit display unit" are "agricultural work unit display unit", "first agricultural work unit display unit", and "second agricultural work unit", respectively. It can be read as "display unit". In addition, "spraying status", "spraying state", "spraying material spraying", and "spraying material spraying locus" should be read as "working status", "working state", "work", and "working locus", respectively. Can be done.

As the agricultural machine 1 to which the above-mentioned display device 61 can be applied, for example, an agricultural machine (for example, a mower, an offset mower, a boom mower, etc.) that performs a mowing work as an agricultural work can be exemplified. In this case, the agricultural work department is the mowing department.
When the agricultural machine 1 is a normal mower (a mower whose mowing portion does not swing to the left or right), the agricultural work unit has a first mowing portion located to the left of the traveling vehicle body and a second mower located to the right of the traveling vehicle body. Including the mowing part. In this case, the first agricultural work display unit indicates the work state in which the first mowing unit works on the left side of the traveling vehicle body, and the second agricultural work display unit indicates the work state in which the second mowing unit works on the right side of the traveling vehicle body. Indicates the working status.

When the agricultural machine 1 is an offset mower or a boom mower, the mowing portion swings left and right with respect to the traveling vehicle body. In this case, the first agricultural work display unit shows the work state in which the mowing unit works on the left side of the traveling vehicle body, and the second agricultural work display unit indicates the work state in which the mowing unit works on the right side of the traveling vehicle body. ..
<Display of margin of running speed for spraying ability>
As shown in FIG. 8, the agricultural machine 1 includes a speed sensor 63c that detects the traveling speed of the machine body 2 (traveling vehicle body 8). The speed sensor 63c can transmit the detected information (speed value) regarding the traveling speed of the aircraft 2 to the control device 60. In the example shown in FIG. 8, the speed sensor 63c is provided in the positioning device 63, but the speed sensor 63c may be provided separately from the positioning device 63. For example, the speed sensor 63c may calculate the traveling speed of the machine body 2 (traveling vehicle body 8) from the rotation speed (rotational speed) of the front wheels 3F or the rear wheels 3R.

The amount of spraying (spraying capacity) per unit time in the agricultural machine 1 is uniquely determined by the planned spraying value (amount to be sprayed), the traveling speed of the machine 2 (current speed value), and the spraying width. For example, the unit of spraying amount per unit time is "kg / sec", the unit of spraying plan value is "kg / a", the unit of traveling speed of the aircraft 2 is "m / sec", and the unit of spraying width is "m". ". The spraying planned value is a planned value of the spraying amount required per unit time, and is, for example, the set spraying amount Wn input to the spraying input unit 107 described above. The spraying width can be calculated from the length of the first pipe 15L and the length of the second pipe 15R. As described above, the length of the first tube 15L and the second tube 15R are stored in the control device 60. Therefore, the control device 60 can calculate the spray width based on the stored length of the first pipe 15L and the second pipe 15R.

The control device 60 calculates the spraying amount (spraying capacity) per unit time required at the present time from the current speed value detected by the speed sensor 63c, the spraying plan value, and the spraying width, and the spraying amount (spraying capacity) is calculated. The driving device that operates to change the amount of spraying by the spraying unit 22 is driven so as to realize the ability). In the case of the present embodiment, the driving devices that operate to change the amount of spraying by the spraying unit 22 are the first electric motors 14L and 14R. However, the drive device that operates to change the spray amount by the spray unit 22 is not limited to the first electric motors 14L and 14R, and may be other drive devices (for example, the second electric motor 35 or the like) described above. You may. In the following description, it is assumed that the drive device is the first electric motors 14L and 14R.

The control device 60 calculates the spraying amount (spraying capacity) per unit time required at the present time from the current speed value detected by the speed sensor 63c, the spraying plan value, and the spraying width, and the spraying amount (spraying capacity) is calculated. The first electric motors 14L and 14R are driven so as to realize the capacity). However, since the first electric motors 14L and 14R are set to the maximum rotation speed in the specifications, there is a threshold value (upper limit) that cannot be dealt with depending on the combination of the current speed value and the spraying plan value.

More specifically, when the current speed value increases, it is necessary to increase the rotation speeds of the first electric motors 14L and 14R in order to realize the current required spraying amount (spraying capacity) per unit time. .. However, if the current speed value becomes too large, it becomes impossible to increase the rotation speed due to the specifications of the motor. Therefore, there is a threshold value (upper limit) for the traveling speed at which the required spraying amount per unit time can be realized. Hereinafter, this threshold value is referred to as a "maximum speed value".

The control device 60 sets the current speed value, which is the current running speed of the aircraft 2 detected by the speed sensor 63c, and the maximum speed value, which is the maximum value of the running speed that can realize the required spraying amount per unit time. Based on this, the margin of the current speed value with respect to the maximum speed value (a numerical value indicating how much the current speed value has a margin with respect to the maximum speed value) is calculated and displayed on the display device 61.
As shown in FIG. 8, the agricultural machine 1 includes an input unit 61d for inputting an element used for calculating the margin (hereinafter, referred to as an “input element”). Although FIG. 8 shows an example in which the input unit is provided in the display device 61, the input unit 61d may be provided in an external device (fixed terminal 75 or server 70). The input unit 61d may be displayed as a portion (input field) in which an input element can be input on the display screen of the display unit 61c (which may be the display unit of the fixed terminal 75 or the server 70) of the display device 61. However, it may be a reading device that reads an input element stored in a storage medium such as a USB memory or an SD card, or both may be used in combination according to the type of the input element.

The control device 60 calculates and calculates the maximum speed value based on the input element input to the input unit 61d. The input element input to the input unit 61d includes the above-mentioned spray width and spray planned value. Further, the input elements include a metering value indicating the amount of spraying sprayed from the spraying unit 22 in a fixed time, a motor specification value including the maximum rotation speed of the motor (first electric motor 14L, 14R) which is a driving device, and a motor specification value. Calculation function (rotation speed calculation curve) for calculating the rotation speed (rpm) of the motors (first electric motors 14L, 14R) based on the metering value and the spraying capacity (spraying amount per unit time required at present). And the planned spraying value.

The metering value is used to calculate the rotation speed of the motor from the spraying capacity using a calculation function. The metering value can be calculated by actual measurement. For example, the sprayed material can be sprayed from the spraying unit 22 for a certain period of time (for example, 60 seconds), and the sprayed amount at this time can be measured and used as a metering value.
The calculation function (rotational speed calculation curve) is a function (relational expression) for calculating the rotational speed of the motor with the metered value and the current required amount of spraying per unit time (spraying capacity) as variables. ..

The spraying plan value is set individually for each of a plurality of areas formed by partitioning the field. This area corresponds to the plurality of areas Qn (n = 1, 2, 3 ... N) described above. In this case, the control device 60 uses the spraying plan values individually set for each of the plurality of areas Qn as input elements, and calculates the maximum speed value for each of the plurality of areas. When different spraying plan values are set for each of the plurality of areas Qn, different maximum velocity values are calculated for each area. When the same spraying plan value is set for all area Qn, the same maximum velocity value is calculated for all area Qn.

Further, the control device 60 may calculate the maximum speed value by using the maximum spraying plan value among the spraying plan values individually set for each of the plurality of areas Qn as an input element. For example, the planned spraying value (set spraying amount) of the area Q1 is 2.0 kg / 10a, the planned spraying value (set spraying amount) of the area Q2 is 3.0 kg / 10a, and the other area Qn (n ≧ 3). When the spraying plan value (set spraying amount) of is 1.0 kg / 10a, the control device 60 calculates the maximum speed value using the spraying plan value set in the area Q2 as an input element.

Further, the control device 60 may calculate the maximum speed value by using the current spraying value indicating the current spraying amount instead of the spraying planned value as an input element. The current spraying value can be calculated, for example, based on the current settings of the spraying amount adjusting device (first spraying amount adjusting device 11L, second spraying amount adjusting device 11R) by the control device 60.
The control device 60 calculates the ratio of the difference between the maximum speed value and the current speed value to the maximum speed value calculated based on the input element as the margin. That is, the margin = (maximum speed value-current speed value) / maximum speed value. For example, when the maximum speed value is 5 (m / sec) and the current speed value is 4 (m / sec). The margin is calculated as (5-4) / 5 = 0.2, that is, 20%. This margin means that the current speed value has a margin of 20% with respect to the maximum speed value. That is, it means that the required spraying amount per unit time can be realized even if the traveling speed is increased by 20% from the current speed value. In this case, the worker can increase the traveling speed of the agricultural machine 1 to perform the spraying work, thereby improving the work efficiency and completing the work in a short time. Further, for example, when the maximum speed value is 5 (m / sec) and the current speed value is 5 (m / sec). The margin is calculated as (5-5) / 5 = 0, that is, 0%. This margin means that the current speed value has no margin for the maximum speed value. In other words, if the traveling speed is increased above the current speed value, the required amount of spraying per unit time becomes unrealizable. In this case, if the traveling speed of the agricultural machine 1 is increased, the required spraying amount cannot be obtained, so that the worker performs the spraying work while maintaining the traveling speed as it is.

The control device 60 displays the calculated margin on the display device 61. The margin displayed on the display device 61 may be displayed as a numerical value (for example, "20%" or the like), but it is preferable to display the margin as a margin gauge that represents the margin graphically.
FIG. 14 shows a display screen M3 of the display device 61 on which the margin gauge YG is displayed. The margin gauge YG can express the margin by the area or length of the figure Z20 showing the current speed value with respect to the area or length of the figure Z10 showing the maximum speed value. The margin gauge YG is displayed as a bar graph. The color of the figure Z10 showing the maximum speed value is different from the color of the figure Z20 showing the current speed value. In FIG. 14, the figure Z10 showing the maximum speed value is displayed as a vertically long rectangle, and the figure Z20 showing the current speed value is displayed by filling a part of the inside of the figure Z10 showing the maximum speed value. In the case of the margin gauge YG shown in FIG. 14, the whole is the figure Z10 showing the maximum speed value, and the filled part (the part of different colors) in the figure Z10 is the figure Z20 showing the current speed value. The unfilled portion Z30 in the figure Z10 represents the "margin".

The ratio of the area (or length) of the figure Z20 showing the current speed value to the area (or length) of the figure Z10 showing the maximum speed value is set to the ratio of the current speed value to the maximum speed value. For example, when the maximum speed value is 5 (m / sec) and the current speed value is 4 (m / sec) (when the margin is 20%), the area (or the area) of the figure Z10 showing the maximum speed value is shown. Assuming that the length) is 100, the area (or length) of the figure Z20 showing the current velocity value is 80.

FIG. 14 shows a margin gauge YG when the margin is 80%. FIG. 18 shows the margin gauge YG when (a) has a margin = 60%, (b) shows the margin gauge YG when the margin = 20%, and (c) shows the margin gauge YG. The margin gauge YG in the case of% is shown. As described above, in the margin gauge YG, as the margin becomes smaller, the area or length of the figure Z20 showing the current speed value becomes larger with respect to the area or length of the figure Z10 showing the maximum speed value. By displaying the margin on the margin gauge YG in this way, the margin is displayed in a visually easy-to-understand manner, so that the operator can easily and accurately grasp the margin.

As shown in FIG. 14, it is preferable that the margin gauge YG is displayed on the same display screen M3 as the figures (Z1 to Z4) showing the spraying status from the spraying unit 22. In FIG. 14, the operation switch 110 for performing the operation of spraying the sprayed material from the spraying portion, the figures (Z1 to Z4) showing the spraying status from the spraying portion 22, and the margin gauge YG are on the same display screen M3. It is displayed.
As shown in FIG. 8, the agricultural machine 1 is provided with a notification unit 61e for notifying the operator that the margin is equal to or less than the predetermined value when the margin is equal to or less than the predetermined value. The predetermined value is, for example, a margin = 5%. In this case, the notification unit 61e notifies the operator that the margin is 5% or less when the margin is 5% or less. In the example shown in FIG. 8, the notification unit 61e is provided in the display device 61, but the notification unit 61e may be provided in a device different from the display device 61.

The notification unit 61e is, for example, a sound generator (buzzer, speaker, etc.) that notifies by sound or voice, and a light generator (LED, etc.) that notifies by lighting or blinking light. Further, the notification unit 61e may perform notification by displaying (characters, figures, etc.) on the display screen of the display unit 61c of the display device 61. The control device 60 transmits a control signal to the notification unit 61e when the margin exceeds a predetermined value. Upon receiving the control signal, the notification unit 61e notifies the operator that the margin exceeds a predetermined value by a method such as sound, light, or display. As a result, the worker can know that the margin has become equal to or less than the predetermined value, and can take measures such as reducing (or not increasing) the traveling speed. As a result, it is possible to prevent the operator from traveling at a speed exceeding the maximum speed value, and it is possible to prevent a shortage of spraying amount due to excessive speed.

FIG. 19 shows an example of the system configuration and the flow of the processing operation of the agricultural machine 1 for calculating the above-mentioned margin.
In the case of the system shown in FIG. 19, the positioning device 63 includes a speed sensor 63c. The control device 60 is composed of, for example, an ECU (Electric Control Unit) of a motor controller that controls a motor (first electric motors 14L, 14R). The current speed value detected by the speed sensor 63c of the positioning device 63 is transmitted to the control device 60. Further, the positioning device 63 transmits the position (latitude, longitude) of the agricultural machine 1, that is, the position of the traveling vehicle body 8 to the display device 61. The display device 61 transmits the spraying plan value and the metering value to the control device 60. The spraying plan value and the metering value are input from the input unit 61d. The control device 60 calculates the maximum speed value based on the spraying plan value, the metering value, the motor specification value, the calculation function, and the spraying width transmitted from the display device 61.

In calculating the maximum speed value, the control device 60 may calculate the maximum speed value for each of a plurality of areas by using the spraying plan value individually set for each of the plurality of areas Qn as the spraying plan value. Then, the maximum speed value may be calculated by using the maximum spraying plan value among the spraying plan values individually set for each of the plurality of areas Qn. Further, the control device 60 may calculate the maximum speed value by using the current spraying value indicating the current spraying amount instead of the spraying planned value.

The control device 60 calculates the margin based on the current speed value transmitted from the positioning device 63 and the calculated maximum speed value, and transmits the calculated margin to the display device 61. The display device 61 displays the received margin on the display unit 61c in the form of a margin gauge YG or the like (see FIG. 14). Further, when the margin is equal to or less than the predetermined value, the control unit 61a of the display device 61 operates the notification unit 61e to notify the operator that the margin is equal to or less than the predetermined value. Instead of the configuration in which the display device 61 operates the notification unit 61e, the control device 60 may be configured to operate the notification unit 61e.

The control device 60 transmits a control signal to the motor drivers of the first electric motors 14L and 14R. The first electric motors 14L and 14R drive the spraying / discharging mechanism 13 based on the received control signal, and the sprayed material is sprayed from the spraying unit 22.
In the system shown in FIG. 19, the control device 60 may be composed of the control unit 61a of the display device 61, or may be composed of both the ECU of the motor controller and the control unit 61a of the display device 61. When the control device 60 is composed of the control unit 61a of the display device 61, the maximum speed value can be calculated and displayed on the display device 61, so that the system configuration can be simplified. When all or part of the control device 60 is composed of the control unit 61a of the display device 61, the current speed value detected by the speed sensor 63c can be transmitted to the display device 61. Further, the current speed value and the maximum speed value can be transmitted from the control device 60 to the display device 61, and the margin can be calculated by the control unit 61a of the display device 61.
