Description

  The present invention relates to a fertilizer application control device that controls fertilizer application of a fertilizer application device.

  Fertilizer spreaders include broad casters that can adjust the spread width and lime saws that have a fixed spread width. The power related to the fertilizer application of any fertilizer application device is the power rotation transmitted from the engine shaft rotation of the traveling vehicle (for example, tractor) through the PTO (rotation transmission unit). Rotates and fertilizer is sprayed. The rotation speed of the rotation shaft of the spraying unit is proportional to the shaft rotation speed of the traveling vehicle, and the rotation axis of the spraying unit rotates at the rotation speed corresponding to the shaft rotation, and the target fertilizer spreading width, and Fertilizer is sprayed at a fertilizer spray amount per predetermined area. The shaft rotation of the traveling vehicle is related to the traveling speed of the traveling vehicle and travels at a speed corresponding to the shaft rotation.

  By the way, during the fertilizer application, there may be a case where the traveling resistance acts on the traveling vehicle due to the inclination of the farm field and the shaft rotational speed of the engine decreases. When the engine rotational speed decreases, the speed of the traveling vehicle decreases and the rotational speed of the spraying section also decreases, resulting in variations in spraying width and fertilizer spraying amount per predetermined area. If variation occurs in the spread width and fertilizer spread amount per predetermined area, uneven dispersion occurs, which affects crop growth. That is, in order to keep the spread width and fertilizer spread amount per predetermined area constant in the same field, it is a condition that the traveling speed of the traveling vehicle is kept constant, and the operator is most careful during fertilization work Is the running speed.

  The traveling speed of the traveling vehicle is determined based on the work environment values such as cultivated crops, field conditions, fertilizer application width, fertilizer application amount per specified area, and fertilizer physical properties. It is set by calculating and deriving from the quantity graph. In addition, a system for automatically calculating the traveling speed by inputting each work environment value by a sensor or manually is employed, so that troublesome work such as calculating from a spray amount graph based on each work environment value is reduced. (For example, see Patent Document 1).

JP 9-37622 A

  However, the system described in Patent Document 1 receives a lot of information such as the spray amount adjustment position, the remaining amount, the spray amount per predetermined area, the travel speed (vehicle speed), the spray shutter opening, etc. when the nuclear work environment value is input. Is displayed, there is a problem that it is difficult to determine the traveling speed at which the operator is most careful during fertilization work. The displayed traveling speed is the traveling speed in the actual traveling state detected by the vehicle speed detecting means, and is the same as the speedometer provided in the traveling vehicle. In other words, although it is displayed that the traveling speed has dropped due to the inclination of the field during fertilizer spraying, it is difficult to distinguish with many other display information, so the target fertilizer spray width and fertilizer spray per predetermined area There is a risk that the operation for returning to the travel speed required for the amount will be delayed.

And in this ROM and RAM, various programs and various data based on the various requests | requirements of the display switching control part 5 and the shutter opening degree control part 7 are performed.

  The work environment value setting unit 3 includes a display unit 30 that displays the work environment set value, a display switching instruction unit 31 that performs a switching operation of the display of the work environment set value, and an increase side change that changes the value of the work environment set value. An instruction unit 32 and a decrease side change instruction unit 33 are configured. In addition, a traveling speed lighting unit 2A that is lit according to the type of work environment displayed by an instruction of each instruction unit, a spreading width lighting unit 2B, a spreading amount lighting unit 2C, and a fertilizer property lighting unit 2D are provided. Yes.

  The display unit 30 is a display screen that displays each work environment setting value read from the work environment setting value storage unit 10 according to an instruction from the display switching instruction unit 31. The display screen of the display unit 30 may be anything such as a liquid crystal screen or an LED screen.

  The display switching instruction unit 31 sequentially reads out from the work environment set value storage unit 10 the traveling speed value, the target application width value, the application amount value per predetermined area, and the fertilizer physical property value, which are work environment types in the present embodiment. At the same time, the display unit 30 is instructed to sequentially switch to the read value.

The changed value is determined as the work environment setting value and is controlled to be stored (overwritten) in the work environment setting value storage unit 10. Also, what is the displayed work environment setting value is determined by the traveling speed lighting unit 2A, spraying width lighting unit 2B, spraying amount lighting unit 2C, and fertilizer property lighting unit 2D corresponding to the displayed work environment type.

Regarding the fertilizer physical properties in this embodiment, not the unit but the fineness of the fertilizer is displayed. For example, it is displayed as [grain] for granular fertilizer, [sand] for sandy fertilizer, and [powder] for powdered fertilizer (not shown). In addition, when shifting from [grain] to [sand] and from [sand] to [powder], for example, [coarse grain], [medium grain], [fine grain], and [coarse sand], [medium sand] , [Fine sand] or the like, the state of the grains and sand may be divided into about three stages (not shown).

When the last work environment value is set, control is performed so as to recognize that all the work environment values have been set. The traveling speed value displayed here is always displayed during fertilizer application, and is continuously displayed until a new work environment value is set.

  Normally, fertilizers have different fertilizer application distances depending on their physical properties, and the finer the particles, the lighter the application distance, the shorter the application distance. For example, in the case of a fertilizer having a limit value of 6 m, even if the target spreading width is set to 10 m, the spreading width is actually 6 m. Further, the fertilizer to be spread on the field is determined by the crops in the field. Fertilizer is put in the hopper before inputting the value of the fertilizer physical properties, and the physical properties of the fertilizer are set according to the physical properties of the fertilizer in the hopper.

  In other words, since the maximum spread width of fertilizer is determined by the physical properties of the fertilizer, control should be performed so that the spread width exceeding the maximum value corresponding to the physical properties of the fertilizer cannot be set when setting the desired spread width value. Is preferred. Furthermore, it is preferable to control the setting order of the work environment values so that the spread width value can be set at least after the fertilizer physical property values are set.

  Therefore, the fertilizer application control apparatus A of this embodiment is provided with a fertilizer application width value setting control unit A10 and an application width maximum value storage unit A20. The fertilizer application width value setting control unit A10 performs control to enable setting of the target fertilizer application width only after setting the fertilizer physical property values. Further, the fertilizer spreading width value setting control unit A10 reads and displays the maximum value of the spreading width corresponding to the fertilizer physical property value stored in the spreading width maximum value storage unit A20 after setting the fertilizer physical property value, Control is performed so that a value exceeding the maximum value of the spreading width cannot be set.

  In the spreading width maximum value storage unit A20, the maximum value of the spreading width corresponding to the value of the fertilizer physical property is stored, and when the physical property of the fertilizer is set, the maximum value of the spreading width corresponding to the physical property is read.

  When the target spread width value is set, the control of the fertilizer spread width value setting control unit A10 in the present embodiment reads the maximum spread width corresponding to the fertilizer physical property after setting the fertilizer physical property value, and Control is performed in which the maximum value of the spreading width is displayed, and the maximum value is manipulated in a direction to reduce the target spreading width. In this case, the direction of operation (increase / decrease) is monitored, and control is performed so that the operation in the direction of increasing the maximum value of the displayed spread of fertilizer cannot be performed.

  In addition to the above-described control, the control of the fertilizer spreading width value setting control unit A10 is, for example, such that [0] is displayed as the initial value of the target spreading width value after setting the fertilizer physical property value. For example, there is a control in which the value is manipulated and set in the direction of increasing the target spreading width. In this case, the target spread width value to be operated is monitored, and control is performed so that an operation exceeding the maximum value cannot be performed when the maximum spread width value corresponding to the set fertilizer physical property is reached (not shown). )

  Further, as the control of the fertilizer application width value setting control unit A10, when the physical properties of the fertilizer are set, the maximum value of the application width corresponding to the physical properties is read, the maximum value of the application width is displayed, and the maximum value is set. In order not to exceed, there is a control in which monitoring of the target spreading width value to be operated is started. Furthermore, after setting the fertilizer physical property value, the maximum value of the spreading width corresponding to the set fertilizer physical property value is read, the maximum value of the spreading width is displayed, and the maximum value is set as the fertilizer spreading width setting value. The control to set is mentioned (not shown).

  In addition, as control of the fertilizer spreading width value setting control part A10, only the control which enables the setting of the said target fertilizer spreading width after the setting of the value of a fertilizer physical property may be sufficient (not shown).

  The spraying instruction unit 6 includes a fertilizer spraying start instruction unit 60, a fertilizer spraying stop instruction unit 61, and a shutter open state display unit 62 that flashes or is continuously lit according to an instruction from the fertilizer spraying start instruction unit 60. . Then, the shutter opening control unit 5 is requested so that the shutter L is opened by an instruction from the fertilizer application start instruction unit 60 and the shutter L is closed by an instruction from the fertilizer application stop instruction unit 61. Further, the instruction from the fertilizer application start instruction unit 60 is controlled by the shutter opening control unit 7 so as to be effective when all the work environment settings have been completed.

  The shutter opening degree control unit 7 reads out the work environment set value from the work environment set value storage unit 10 in accordance with an instruction from the display switching control unit 5 after the setting of all the work environment values, and the work environment set value data Based on the above, the shutter opening calculation unit 4 is controlled to calculate the shutter opening. The calculated shutter opening is stored (overwritten) in the shutter opening storage unit 11.

  The shutter opening control unit 7 reads out the shutter opening from the shutter opening storage unit 11 in response to a request from the fertilizer application start instruction unit 60, and operates the operating unit in the direction in which the shutter L opens based on the read shutter opening. Control for operating L1 and control for operating the operating unit L1 in the direction in which the shutter L closes are performed in response to a request from the fertilizer application stop instruction unit 61. Specifically, in response to a request from the fertilizer application start instruction unit 60, the shutter L is moved in the opening direction with respect to the operating unit 1, and the shutter L is stopped at a position where the fertilizer dropping port H reaches the opening area. Further, in response to a request from the fertilizer application stop instruction unit 61, the shutter L is moved in the closing direction with respect to the operating unit 1, and the shutter L is stopped at the fully closed position of the fertilizer dropping port H. Further, only when a request to open the shutter L of the fertilizer application start instruction unit 60 is made, a request to close the shutter L of the fertilizer application start instruction unit 60 is made by blinking or continuously lighting the shutter open state display unit 62. When this is done, control is performed to turn off the shutter open state display unit 62.

  The blinking state or the continuous lighting state of the shutter open state display unit 62 is obtained by changing the spray amount value per predetermined area read and displayed by the display switching instruction unit 31 to the increase side change instruction unit 32 and the decrease side change. Also when changing by the instruction unit 33, the shutter open state display unit 62 may be blinked or continuously lit (not shown). Further, the shutter open state display unit 62 may be blinked while the shutter L is operating in either of the opening and closing directions, and may be turned off when the shutter L is in the stopped state.

  In addition, when the power source (power switch 1) is turned off in the open state of the shutter L (when the shutter opening value is not "0"), when the power source is turned on from this off state, the power source is turned off. And the shutter opening value may be blinked on the display unit 30 to notify the operator that the shutter L is open (not shown). ) In this case, it is preferable to perform control so that only the operation to the fertilizer application stop instruction unit 61 is effective (a state in which other operations are not accepted) (not shown). That is, when the power is turned on, it is possible to notify that the shutter L is in an open state and to restrict the shutter L from operating freely.

  Note that the structure of the operating portion L1 of the shutter L is such that the rotation of the motor is transmitted to the opening and closing operation of the shutter L by, for example, a motor and a gear mechanism disposed between the rotation shaft of the motor and the shutter L. And a structure (not shown) that opens and closes the shutter L by expansion and contraction of the cylinder actuator. In any structure of the operating unit L1, the motor and actuator are driven and controlled by the shutter opening control unit 7.

  According to the fertilizer application control device A of the present embodiment, only the traveling speed value that can always maintain the target application width is displayed during fertilizer application. Therefore, it is easy to confirm the traveling speed value that can maintain the target spreading width, and when the traveling speed decreases due to the field conditions during the spraying operation, the traveling speed value that is necessary to maintain the target spreading width is restored. Can be performed quickly.

In this embodiment, these steps are performed in the order of the fertilizer physical property value, the target spray width value, the traveling speed value, and the spray amount value per predetermined area.

  Specifically, the value of the fertilizer physical property is read and displayed (step S2), and the displayed value of the fertilizer physical property is changed (step S3). The changed value of the fertilizer physical property is stored (overwritten) (step S4), and at the same time, the spread width value is read from the storage unit 2, and the spread width value is displayed in place of the fertilizer physical property value (step S5). At this time, the displayed spreading width value is the maximum spreading width corresponding to the fertilizer physical properties stored in the spreading width maximum value storage unit A20.

  The displayed spread width is changed to the target spread width value by operating in the direction of decreasing the maximum value (step S6). The displayed spread width value is stored (overwritten) (step S7), and at the same time, the travel speed value is read and displayed in place of the spread width value (step S8). The displayed traveling speed value is changed (step S9). The changed travel speed value is stored (overwritten) (step S10), and at the same time, the spray amount per predetermined area is read and displayed in place of the spray width value (step S11). The displayed application amount value is changed (step S12). The changed application amount value is stored (overwritten) (step S13).

  Then, all the work environment setting values are stored in steps S2 to S13, and at the same time as the end of step S13, the stored traveling speed value is read (step S14), and the traveling speed value is displayed. (Step S15). The display of the traveling speed value is continued until the fertilizer application control device A is stopped (the power switch unit 1 is turned OFF) or each work environment value is newly set. Accordingly, during the fertilizer application, the traveling speed value, which is the information that the operator wants to know most, is always displayed.

  In this embodiment, simultaneously with the end of step S13, each stored work environment value is read (step S16), and a shutter opening value is calculated based on each work environment value (step S17). The stored shutter opening value is stored (overwritten) (step S18).

  Through the above steps S1 to S18, the traveling speed at which the fertilizer can be sprayed with the target spray width is displayed, and preparation for spraying the fertilizer with the target spray width can be made. In response to an instruction to start fertilizer application (step S19), the stored shutter opening value is read (step S20), and the shutter L is moved in the opening direction based on the shutter opening value, so that the fertilizer dropping opening is obtained. H is the opening area that is the required fertilizer fall amount (step S21). Then, after the fertilizer spraying is finished, in response to an instruction to stop fertilizer spraying (step S22), the shutter L moves in the closing direction and the fertilizer dropping port H is closed (step S23).

  According to the program of this embodiment, after setting each work environment, it is one of the information that the operator wants to know most during the fertilizer spraying, and the control for displaying the traveling speed value necessary to maintain the target spraying width is performed. Can be executed.

This rotational speed is the optimum rotational speed for maintaining the target spreading width, and the target spreading width can be maintained by maintaining this rotational speed. The calculation of the number of rotations is not limited to the number of rotations of the rotation shaft I, and may be anywhere in the rotation transmission path from the drive shaft of the traveling device C to the rotation shaft I of the fertilizer spraying unit E.

  According to the fertilizer application control device A ′ of the present embodiment, only the rotational numerical value that can always maintain the target application width is displayed during fertilizer application. Therefore, it is easy to check the rotation value that can maintain the target spreading width, and the target spreading width is maintained when the traveling speed decreases due to the field condition during the spraying operation and the rotation speed of the rotary shaft I decreases. Therefore, the operation for returning to the required number of rotations can be performed quickly.

The calculated rotation value is stored (overwritten) (step S16). Further, the stored rotation value is read (step S17), and the rotation value is displayed (step S18). The display of the rotation value is continued until the fertilizer application control device A ′ is stopped (the power switch unit 1 is turned OFF) or each work environment value is newly set. Therefore, during the fertilizer application, the rotation value of the rotation axis I, which is one of the information that the operator wants to know most, is always displayed.

  Also in this embodiment, simultaneously with the end of step S13, each stored work environment value is read (step S19), a shutter opening value is calculated based on each work environment value (step S20), and the calculated shutter opening is calculated. Value storage (overwriting) (step S21) is performed.

  Through the above steps S1 to S21, the number of rotations at which the fertilizer can be sprayed with the target spray width is displayed, and preparations for fertilizer spraying with the target spray width can be made. Then, in response to an instruction to start fertilizer application (step S22), the stored shutter opening value is read (step S23), and the shutter L is moved in the opening direction based on the shutter opening value, so that the fertilizer dropping opening is obtained. H is the opening area that is the required fertilizer fall amount (step S24). Then, after the fertilizer spraying is finished, in response to an instruction to stop fertilizer spraying (step S25), the shutter L moves in the closing direction and the fertilizer dropping port H is closed (step S26).

  According to the program of the present embodiment, after setting each work environment, one of the information that the operator wants to know most during the fertilizer spraying is displayed, and the rotation numerical value of the rotation axis I necessary to maintain the target spraying width is displayed. Control can be executed.

  The fertilizer application control device A ′ of the illustrated embodiment performs control to display the rotational numerical value after completion of setting of all work environment values, but in the present invention, after completion of setting of all work environment values. It includes a control that displays the rotation value in response to an instruction to start fertilizer application (not shown). This control can always display the rotation numerical value, which is one of the information that the operator wants to know most during the fertilizer application.

  FIG. 7 is a block diagram showing an outline of the overall configuration of a fertilizer application control device A ″ according to another embodiment. The configuration of the fertilizer application control device A ″ according to the present embodiment is a rotation that detects the rotation value of the rotation axis I of the warning unit 1A and the fertilizer application unit E in addition to the configuration of the fertilizer application control device A shown in FIG. A number detection unit 2A, and a warning control unit 3A that controls the warning unit 1A to perform a warning operation when the detected rotational numerical value is a value that cannot maintain the target spreading width. In addition, the description about the structure which overlaps with the structure of the said fertilizer spreading control apparatus A is abbreviate | omitted by attaching | subjecting the same code | symbol.

  The warning unit 1A may be configured to be able to reliably notify the operator who is working that the rotational speed of the rotary shaft I has decreased. ), And / or flashing lights for visual warning.

  The rotation speed detection unit 2A detects the rotation speed of the rotary shaft I during fertilizer spraying and sends the detected rotation speed data to the warning control unit 3A. Further, the rotation speed detection of the rotation speed detection unit 2A is performed when the shutter L is open and the rotation shaft I is rotating, that is, when fertilizer spraying is performed. In addition, the detection place of rotation speed is not restricted to the rotating shaft I, but may be anywhere in the rotation transmission path from the driving shaft of the traveling device C to the rotating shaft I of the fertilizer spraying section E. The rotation speed detection may be performed when the shutter L is closed and the rotation transmission path from the drive shaft of the traveling device C to the rotation shaft I of the fertilizer application unit E is rotating.

  The warning control unit 3A determines, based on the received rotation numerical data, whether or not the rotation numerical value is a rotation numerical value that cannot maintain the target spraying width, and the determination result is a rotational numerical value that cannot maintain the target spraying width. Sometimes, control is performed to warn the warning unit 1A. In addition, when it is determined that the rotation value is maintained to maintain the target spreading width, control is performed to stop the warning and maintain the warning stopped state. At this time, the warning control unit 3A reads the travel speed value from the work environment set value storage unit 10 and calculates the rotation speed corresponding to the travel speed value. Then, the calculated rotational numerical value is compared with the detected rotational numerical value, and when the rotational numerical value of both is different, it is determined that the rotational numerical value cannot maintain the target spreading width.

  According to the fertilizer application control device A ″ of the present embodiment, the traveling speed value for maintaining the target application width is displayed on the display unit 30, and the rotation speed of the rotation axis I indicates the target application width. A warning is issued when the rotation number cannot be maintained. That is, the operator can be notified by a warning that the spraying width has changed due to a decrease in the rotational speed of the rotating shaft I accompanying a decrease in traveling speed during the spraying operation. Therefore, since it is possible to know more quickly that the spraying width has changed, an operation for returning to the rotational speed of the rotation axis I necessary to maintain the target spraying width, that is, the traveling speed is displayed. The operation of returning to the traveling speed value can be performed more quickly.

  FIG. 8 is a flowchart of a program including a method in which the warning control unit 3A issues a warning to the warning unit 1A. This program is a program that is started when a fertilizer application start instruction is given to the fertilizer application control device A (step S1). When the start of fertilizer application is instructed, detection of the rotational speed of the rotary shaft I is started (step S2). When the detected rotational numerical value is a rotational numerical value that cannot maintain the target spreading width (step S3), the warning unit 1A is warned (step S4). The detection of the rotational speed is continued even during the warning (step S5), and when the rotational numerical value detected during the warning is the rotational numerical value that maintains the target spreading width (step S6), the warning of the warning unit 1A is stopped. (Step S7). Then, this program continues from Step 2 to Step 7 unless a fertilizer spraying stop instruction is issued to the fertilizer spray control device A.

  According to the program of the present embodiment, it is possible to execute control for giving a warning to the warning unit 1A.

  The illustrated warning unit 1A, rotation speed detection unit 2A, and warning control unit 3A can also be applied to the fertilizer application control device A ′ of other embodiments. Further, instead of the rotation speed detection unit 3A, a travel speed detection unit (not shown) for detecting the speed of the travel device is used, and the travel speed value is set based on the travel speed value data received by the warning control unit 3A. It is determined whether or not the traveling speed value cannot maintain the spreading width, and when the determination result is the traveling speed value that cannot maintain the target scattering width, control is performed to warn the warning unit 1A. It is good (not shown).

  All of the exemplified fertilizer application control devices are applied to broad casters, but the fertilizer application control device of the present invention can also be applied to lime saw (not shown). Since lime sower has a fixed fertilizer spread width, the setting of the work environment value is the traveling speed value, the target application amount per predetermined area, the fertilizer physical property value, and based on these work environment setting values, Control is performed to operate the shutter so as to achieve a target spray amount per predetermined area (not shown). After all the work environment values have been set, a traveling speed value that can maintain the target spraying amount per predetermined area, or a rotational numerical value of the rotating shaft is displayed (not shown). Therefore, it is easy to check the running speed value or rotation value that can maintain the desired spraying amount per predetermined area, and when the running speed decreases due to the field condition during the spraying work and the rotation speed of the rotating shaft decreases The operation for returning to the traveling speed or the rotational speed necessary for maintaining the target spray amount per predetermined area can be quickly performed. The fertilizer application control device applied to this lime saw also includes control for displaying a traveling speed value or a rotation value in response to an instruction to start fertilizer application after completion of setting all work environment values (not shown).
