Description

The present invention relates to an information processing system that notifies the user when it is time to replace the tiller tines attached to a rotary working machine.

A work vehicle capable of tilling work is known from the related art, which is described in Patent Document 1 and includes a running body equipped with an engine, and a rotary working machine that is connected to the running body so as to be driven to rotate by power transmitted from the engine and that performs tilling work using replaceable tilling tines, and which is configured to detect and notify the user when it is time to replace the tilling tines by using tilling tines with wiring running along the blade portion as sensors for detecting the degree of wear.

With a work vehicle of this configuration, it is possible to detect when the tilling tines have worn beyond a certain level by detecting when the wiring on the tilling tines has broken, allowing the operator to easily know when it is time to replace the tilling tines. However, this requires wiring for each tilling tine and a mechanism for detecting the current flow state of the wiring on the tilling tines, which is costly and time-consuming. In addition, if the wiring breaks for reasons other than tine wear, it may not be possible to notify the operator that it is time to properly replace the tilling tines.

JP 2019-103431 A

The present invention aims to provide an information processing system that can notify the operator when it is time to replace the tiller tines at a more appropriate time in a work vehicle equipped with a rotary work machine in which the tiller tines are replaceable.

In order to solve the above-mentioned problems, the present invention provides an information processing system that estimates a wear condition of a tillage tine that is detachably attached to a rotary working machine and notifies the time to replace the tillage tine, the information processing system including a communications terminal provided on a work vehicle to which the rotary working machine is connected so as to be able to rise and fall, and a management server connected to the communications terminal via a network, the communications terminal having a work machine information acquisition unit that acquires work information indicating an operating status of the rotary working machine by the work vehicle, a replacement information acquisition unit that acquires replacement information indicating that replacement work of the tillage tine has been performed by the rotary working machine, and a notification means , the management server having a storage device, a work information receiving unit that receives the work information transmitted via the network, a replacement information receiving unit that receives the replacement information transmitted via the network, a wear degree estimation unit that estimates the wear degree of the tillage tine based on the work information, a determination unit that determines when to replace the tillage tine based on the wear degree estimated by the wear degree estimation unit, and a notification means that determines when the time to replace the tillage tine has passed based on the wear degree estimated by the wear degree estimation unit. the rotary working machine itself is a parameter that determines whether or not the tilling tines need to be replaced, and the wear degree estimation unit is configured to estimate the wear degree based on the work time, and then correct the wear degree using the control parameters, the field parameters, and the working machine parameters. The rotary working machine has a wear degree estimation unit that estimates the wear degree based on the work time, and then corrects the wear degree using the control parameters, the field parameters, and the working machine parameters.

The work information may include a tine replacement time, which is the work time performed between when the tilling tine is attached to the rotary work machine and when the tilling tine is replaced, and the judgment unit may be configured to judge that it is time to replace the tilling tine when the work time counted from when the tilling tine is attached to the rotary work machine exceeds the tine replacement time.

The communications terminal may have a position information acquisition unit that acquires position information of a work vehicle, the management server may have a field data storage unit in which field information is stored in the memory device, and the wear degree estimation unit may be configured to estimate the wear degree of the tiller tines based on the position information of the work vehicle and taking into account the field information acquired from the field data storage unit.

The tillage tine dealer may have a sales information terminal, and the sales information terminal may have a communication unit that enables communication via the network, and an exchange information receiving unit that receives exchange information when the exchange information indicating that the tillage tine replacement work has been performed on the rotary work machine is transmitted via the network.

The replacement time notification system calculates the wear level of the tilling tines based on work information that indicates the operating status of the traveling body and the rotary work machine during tilling work, and can automatically notify the worker when it is time to replace the tilling tines. This allows the worker to replace the tilling tines at the appropriate time without having special knowledge. This allows tilling work to be performed more efficiently without reducing work efficiency.

The work information includes a tine replacement time, which is the amount of work performed between when the tilling tines are attached to the rotary working machine and when the tilling tines are replaced, and the determination unit is configured to determine that it is time to replace the tilling tines if the work time counted from when the tilling tines are attached to the rotary working machine exceeds the tine replacement time. This makes it possible to correct the work time until the tilling tines are replaced depending on the field in which the tilling work is performed, making it possible to replace the tilling tines at a more appropriate time and improving workability.

In addition, the communication terminal has a position information acquisition unit that acquires position information of the work vehicle, the management server has a field data storage unit in which field information is stored in the storage device, and the wear degree estimation unit is configured to estimate the wear degree of the tilling tines taking into account the field information acquired from the field data storage unit based on the position information of the work vehicle, thereby improving the calculation accuracy of the wear degree of the tilling tines with a low-cost configuration.

In addition, if the tillage tine dealer is equipped with a sales information terminal which has a communication unit that enables communication via the network and a replacement information receiving unit that receives replacement information when replacement information indicating that the tillage tine replacement work has been performed on the rotary work machine is transmitted via the network, the tillage tine dealer can quickly grasp the replacement status of the tillage tines of the rotary work machine owned by the worker, making the tines more smoothly replenished and resulting in improved workability.

Figure 1 is a conceptual diagram showing an information processing system to which the present invention is applied. The information processing system that notifies the time to replace the tilling tines 9 of a rotary tilling device 8 includes a communication terminal (working machine side terminal 3A) 3 provided on the side of a work vehicle 6 to which a rotary tilling device (rotary working machine) is connected so that it can be raised and lowered, a user terminal 3B which is a communication terminal such as a smartphone or mobile phone used by a worker who operates the work vehicle 2, a management server 1 connected via a network 2 to determine when the tilling tines 9 should be replaced, and a sales side terminal 4 connected to a terminal of a dealer that sells the tilling tines.

In this information processing system, the management server 1 estimates the degree of wear of the tilling tines 9 detachably attached to the rotary tilling device 8 based on the work information transmitted from the work vehicle 6, and when it determines that it is time to replace the tilling tines 9, it can notify the worker on the work vehicle 6 to urge him or her to replace the tilling tines 9. Each component will be described in detail below.

Figure 2 is an overall side view of an agricultural tractor to which the present invention is applied. This tractor, which is a type of work vehicle, is equipped with a pair of left and right front wheels 51, 51 and rear wheels 52, 52, a running body 7 supported by the front and rear wheels 51, 52, and the rotary tilling device 8, which is a working machine connected to the rear of the running body 7 via a lifting link so that it can be raised and lowered. When the rotary tilling device 8 is raised and lowered to the working height on the field side, the rotary tilling device 8 can be driven to perform tilling work on the field.

The rotary tilling device 8 is connected to the lifting link side via a hitch mechanism 53 at the front center, and is mounted at the rear of the traveling body 7 so that it can be raised and lowered by the extension and contraction of a lifting cylinder. The rotary tilling device 8 is also connected via a universal joint to a PTO shaft 54 that protrudes rearward from the rear end side of the traveling body 7, so that power transmitted from the engine on the traveling body 7 side is input to the rotary tilling device 8.

The rotary tilling device 8 has a vertical transmission case 56 through which the power transmitted from the PTO shaft 54 is transmitted, a rotary 57 that performs tilling work by rotating and driving with the power transmitted by the lower side of the transmission case 56, side covers 58, 58 supported on the left and right sides of the rotary 57 so that it can swing back and forth (up and down), a rear cover 59 that is disposed between the pair of left and right side covers and covers the area extending to the upper rear of the rotary, and a flap lever that allows the vertical position of the rear cover 59 to be adjusted, and the rear cover 59 is supported on one side by a mid cover (not shown) connected to its upper end side (see FIG. 2).

The rotary tilling device 8 configured as described above is configured to perform tilling work by driving the rotary 57 in a forward rotation direction (counterclockwise in the example shown in FIG. 1) while driving the traveling body 7 forward, thereby tilling the soil in the field with the rotary 57 and leveling the tilled soil sent to the rear of the rotary 57 with the rear cover 59. The rotary tilling device 8 can also perform plowing work, which mixes the soil in the paddy field to make it a colloidal mud and makes the field surface uniform.

The rear cover 59 is configured so that, by setting the support position of the rear end (lower end) of the mid cover to a lower position, it can be switched to a standard position (see FIG. 2) in which the rear cover 59 is supported in a state in which it is extended downward toward the rear along the rotary 57, and by setting the support position of the rear end (lower end) of the mid cover to an upper position, it can be switched to a deep plowing position (not shown) in which the rear cover 59 is supported so as to extend horizontally from the upper rear side of the rotary 57 toward the rear, and by operating the flap lever with the rear cover 59 switched to the standard position, it can be switched to a plowing position (not shown) in which the lower end of the rear cover 59 is extended downward so as to contact the ground.

According to this configuration, when the rear cover 59 is set in the standard position, the space between the rear cover 59 and the rear of the rotary 57 is narrowed, and the tilled soil is rotated around more frequently, whereas when the rear cover 59 is set in the deep tillage position, the space between the rear cover 59 and the rear of the rotary 57 is widened, and the tilled soil flows more smoothly.

The rotary 57 is composed of a rotary shaft (not shown) in the left-right direction that is supported on the lower side of the transmission case 56, and the tilling tines 9 that are arranged side by side along the rotary shaft. The tilling tines 9 extend radially from the rotary shaft side toward the tip side, and are configured so that they are curved toward the reverse direction of the rotary 57 (see FIG. 2).

In addition, if the tilling tines 9 wear down beyond a certain level due to repeated tilling operations, the efficiency of the tilling operation will decrease significantly. Therefore, when the tilling tines 9 wear down beyond a certain level, each tilling tine 9 is configured to be smoothly attached and detached from the rotary shaft so that it can be replaced.

In response to this, the management server 1 is configured to estimate (predict) the degree of wear of the tilling tines 9 based on work information consisting of various data indicating the operating status of the traveling machine body 7 and the rotary tilling device 8 transmitted from the work vehicle 6, and to execute tilling tine friction diagnosis control that determines and notifies the worker of the appropriate time (timing) to replace the tilling tines 9. The specific configuration of the management server 1 will be described later.

When estimating the degree of wear of the tilling tines 9, the management server 1 is configured to use the work information acquired from the work vehicle 6 as a parameter that determines the degree of wear of the tilling tines 9, and also to parameterize and take into account various other factors. The following describes a method for estimating (diagnosing) the degree of wear of the tilling tines.

Figure 3 is a table showing examples of parameters to be considered in wear prediction.

First, for each type of tilling tine 9, a predetermined degree of wear required for replacement is preset, at which it becomes difficult to maintain the efficiency of tilling work, and a predetermined standard tine replacement time is preset, indicating the working time until the tilling tine 9 needs to be replaced (until the wear of the tilling tine reaches the replacement wear degree) when tilling work is performed in a typical field using a typical method.

At this time, since the strength of the tilling tines 9 differs depending on the type of tilling tines 9 attached to the rotary 57, a standard tine replacement time appropriate for the type of tilling tines 9 attached is set.

Regarding the method of calculating the degree of wear of the tilling tines 9, the management server 1 is configured to determine whether the state of the tilling tines 9 is more worn or less worn than a predetermined degree of wear based on the work information (control parameters) acquired by various sensors, and to calculate a tine replacement time that predicts the work time that will require replacement of the tilling tines 9 by correcting the standard tine replacement time.

More specifically, the degree of wear of the tilling tines 9 is less likely to wear out when the tilling depth during tilling work is shallower than the standard, but is more likely to wear out when the tilling depth during tilling work is deeper than the standard. Also, the degree of wear of the tilling tines 9 is less likely to wear out when the rotation speed of the PTO shaft (the driving speed of the rotary) is lower than the standard, but is more likely to wear out when the rotation speed of the PTO shaft is higher than the standard. Also, the degree of wear of the tilling tines 9 is less likely to wear out when the vehicle speed during tilling work is slower than the standard, but is more likely to wear out when the vehicle speed is faster than the standard. Also, the degree of wear of the tilling tines 9 is less likely to wear out when the rotary tilling device 8 is in a mode in which tilling work is performed, but is more likely to wear out when tilling work is performed than when tilling work is performed (see FIG. 2).

Similarly, the degree of wear of the tilling tines 9 is calculated by inputting field parameters, which are data indicating the condition of the field where tilling work is actually performed, so that the degree of wear (tine replacement time) can be calculated taking into account the field conditions.

Specifically, the degree of wear of the tilling tines 9 is greater the more clayey the soil in the field is, but greater the more sandy the soil in the field is. Also, the degree of wear of the tilling tines 9 is greater the less moisture the soil in the field is, but greater the more moisture the soil in the field is. Also, the degree of wear of the tilling tines 9 is greater the less moisture the soil in the field is, but greater the more moisture the soil in the field is. Also, the degree of wear of the tilling tines 9 is greater the less moisture the soil in the field is, but greater the more moisture the soil in the field is (see Figure 3).

At this time, the management server 1 can apply appropriate field parameters for the field during work travel based on the field parameters acquired in advance and the position information of the work vehicle acquired from the work vehicle (a position information acquisition device such as GPS).

Furthermore, the wear rate of the tilling tines 9 can be corrected by inputting the mounting position of the rear cover 59 as a parameter. Specifically, the wear rate of the tilling tines 9 is less likely to wear when the mounting position of the mid cover is set to an upper position and the rear cover 59 is switched to the deep tillage position, whereas the wear rate of the tilling tines 9 is more likely to wear when the mounting position of the mid cover is set to a lower position and the rear cover 59 is switched to the normal position than when the mid cover is set to an upper position (the rear cover 59 is switched to the deep tillage position) (see FIG. 3).

Figure 4 is a block diagram showing the configuration of the management server. The management server 1 includes a control unit 11 that is composed of a CPU or RAM and is capable of performing various processes by executing various programs, a storage device 12 that stores various information and constitutes part of the storage device of the information processing system, and a communication interface 13 that enables communication via a network.

The control unit 11 includes a work information receiving unit 11a that receives the work information acquired on the work vehicle 6 side and transmitted via the network 2 and stores it in the storage device, an exchange information receiving unit 11b that receives exchange information indicating that the tilling tines 9 of the rotary tilling device 8 have been replaced from the communication terminal of the work vehicle 6 side transmitted via the network 2 and stores it in the storage device, and a wear degree estimation unit 11c that estimates the wear degree of the tilling tines 9 based on the work information. The system includes a determination unit 11d that determines when to replace the tilling tines 9 based on the degree of wear estimated by the wear degree estimation unit 11c, a notification unit (notification transmission unit) 11e that transmits notification information to the communication terminal 3 side to notify that the tilling tines 9 need to be replaced by the determination unit 11d, and a re-notification unit (re-notification transmission unit) 11f that transmits notification information to the communication terminal 3 side again to encourage the tilling tines to be replaced if the tilling tines have not been replaced for a predetermined period after the notification by the notification unit 11e.

The wear degree estimation unit 11c is configured to estimate the wear degree of the tilling tines 9 by taking into consideration control parameters such as tilling depth during tilling work, PTO rotation speed, vehicle speed, and work time during work travel acquired from the work information, field parameters indicating the state of the field in which tilling work is performed, and work machine parameters indicating the set position of the rear cover of the work machine, and to correct the standard tine replacement time preset for the tilling tines 9 to calculate the tine replacement time indicating the work time until the tilling tines are prompted to be replaced.

When the judgment unit 11d judges that the work time using the tilling tines 9 acquired from the work information exceeds the tine replacement time calculated by the wear degree estimation unit 11c, the judgment unit 11d is configured to transmit notification information to the communication terminal 3 (work vehicle terminal 3A, user terminal 3B) on the work vehicle side to advise the worker that the tilling tines 9 have worn down beyond a predetermined level and therefore should be replaced, thereby informing the worker of this.

The storage device 12 includes a work information storage unit 12a, which is a data storage area in which the work information received by the work information receiving unit 11a is stored, an exchange information storage unit 12b, which is a data area in which the exchange information received by the exchange information receiving unit 11b is stored, and a field data storage unit 12c, which is a data area in which field information indicating the state of the field in which the work run is to be performed, which has been installed in advance or obtained via a network, is stored.

Figure 5 is a block diagram showing the configuration of the communication terminal, and Figure 6 is a block diagram showing the detailed configuration of the communication terminal. The communication terminal 3 includes a control unit 31 that is composed of a CPU or RAM and is capable of performing various processes by executing various programs, a storage device 32 that stores various information and constitutes part of the storage device of this information processing system, a communication interface 33 that enables communication via a network, a work information acquisition unit 34 that acquires the work information consisting of operation information and position information of the work vehicle (traveling machine body and rotary tillage device), and a touch panel 36 that has a display means (alert means) and an operation means (exchange information acquisition unit).

The control unit 31 has a work information transmission unit 31a that transmits the work information acquired by the work information acquisition unit 34 to the management server 1 side via the network 2, an exchange information transmission unit 31b that transmits exchange information indicating that the replacement work of the tillage tines 9 of the rotary tillage device 8 has been performed via the touch panel 36 or the like to the management server 1 side via the network 2, and a notification information receiving unit 31c that receives information from the management server 1 side via the network 2 to encourage the replacement of the tillage tines 9.

The work information includes the vehicle speed of the traveling body 7, the engine RPM, the tilling depth during tilling work, the RPM of the PTO shaft 54, and the lift height of the rotary tilling device 8. The replacement information includes data such as the date and time when the tilling tines 9 were replaced, the number of replacements, and the type of tilling tines replaced.

In the above example, the operator is configured to input the replacement information for the tiller tines 9 via the touch panel 36, so that the replacement information can be obtained. However, the rotary tiller 8 may be configured to automatically obtain the replacement work for the tiller tines 9 and automatically transmit the replacement information to the management server 1.

The touch panel 36 functions as an input means for inputting the replacement information, and is also configured to function as an output means for notifying the worker by using images, sounds, etc. to encourage replacement of the tiller tines 9 when information is received from the notification unit on the management server 1 side that the tiller tines 9 need to be replaced.

As shown in Figures 1 and 6, the communication terminal 3 may be composed of a work machine terminal 3A mounted on the work vehicle 6 and a user terminal 3B, which is an information terminal used by the worker.

In this case, the input side of the control unit of the work machine terminal 3A is connected to components equivalent to the work information acquisition unit 34, including a vehicle speed sensor 61 that detects the vehicle speed of the traveling machine body, an engine rotation sensor 62 that detects the engine rotation speed, a tilling depth sensor 63 that detects the tilling depth during tilling work by the rotary tilling device 8, a PTO rotation sensor 64 that detects the PTO shaft rotation speed, a lift arm sensor 66 that detects the lift height of the rotary tilling device, a panel switch 67 that is an input unit provided on the touch panel 36, etc., and a position information acquisition device (not shown) such as a GPS.

The output side of the control unit of the work machine terminal 3A is connected to a display device (notification means) 68 consisting of a monitor or the like that is provided so that it can be viewed inside the cabin, etc.

Furthermore, the control unit of the work machine terminal is provided with a communication unit 33A that transmits the work information acquired by the various sensors described above to the management server side via the network.

The user terminal 3B has the touch panel 36 having a display means (notification means) and an operation means (replacement information acquisition section), and a communication interface 33B that enables communication via a network, and can input and transmit the replacement information from the user terminal 3B held by the worker, and output notification information encouraging replacement of the tiller tines.

Incidentally, the user terminal 3B may also be equipped with a route management function that receives the work route via the network when the work vehicle is cultivating a field, and checks in real time whether the work vehicle is traveling along the work route.

Figure 7 is a block diagram showing the configuration of the sales terminal. The sales terminal 4 includes a control unit 41 that is composed of a CPU or RAM or the like and is capable of performing various processes by executing various programs, a storage device 42 that stores various information and constitutes part of the storage device of this information processing system, a communication interface 43 that enables communication via a network, an output unit 44 that is composed of a monitor or the like, and an input unit 46 that is a keyboard or the like for performing input operations and selection operations.

The control unit 41 has an exchange information receiving unit 41a that receives, via the network 2, the exchange information input via the touch panel 36 or the like on the communication terminal 3 and transmitted by the exchange information transmitting unit 31b.

The storage device 42 has an exchange information storage unit 42a, which is a data storage area in which the exchange information received by the exchange information receiving unit 41a is stored.

With this configuration, the dealer of the tiller tines 9 can immediately know when a customer using a specific work vehicle has had the tiller tines 9 replaced, making it easier to secure inventory of the tiller tines 9 and sell new tiller tines.

Next, we will explain the process flow of the tiller tine wear diagnosis control executed by the above-mentioned information processing system. Figure 8 is a process flow diagram of the tiller tine wear diagnosis control.

When the processing flow of the tilling claw wear diagnosis control is started, the process proceeds to step S1. In step S1, information on the operation time of the PTO shaft (the driving time of the rotary tilling device 8) acquired by the work information acquisition unit 34 (control unit 31A) is received, and the process proceeds to step S2. In step S2, information on the rotation speed of the PTO shaft acquired by the PTO rotation 64 sensor is received, and the process proceeds to step S3. In step S3, information on the tilling depth of the rotary tilling device during tilling work acquired by the tilling depth sensor 63 is received, and the process proceeds to step S4. In step S4, information on the lift height of the rotary tilling device acquired by the lift arm sensor 66 is received, and the process proceeds to step S5. In step S5, information on the working state of the rotary tilling device (working machine) is received from various sensors and mode switching operations by the panel switch, and the process proceeds to step S6. In step S6, vehicle speed data of the traveling machine acquired by the vehicle speed sensor 61 is received, and the process proceeds to step S7.

In other words, in steps S1 to S6, the various pieces of work information acquired by the work information acquisition unit 34 are transmitted by the work information transmission unit 31a to the management server 1 side via the network 2, and the work information received by the work information reception unit 11a on the management server 1 side is stored in the work information storage unit 12a of the storage device 12.

In step S7, it is confirmed from the replacement information stored in the replacement information storage unit 12b whether or not this is the first time that the tilling tines 9 attached to the rotary tilling device 8 have been replaced, and if this is the first time that the tilling tines 9 have been replaced, the process proceeds to step S8.

In step S8, the wear degree estimation unit 11c estimates (calculates) the wear degree of the tiller tines 9 based on the work information, and the process proceeds to step S9.

In step S9, the tine replacement time, which is the work time until the tine replacement is required, is calculated based on the degree of wear of the tines 9 estimated by the wear estimation unit 11c, and the process proceeds to step S10.

Incidentally, in step S9, which is before the first claw replacement, if the notification to prompt the user to replace the claws has been issued and the claws are to be replaced, the time until the next notification is calculated as a new claw replacement time based on the estimated degree of wear of the claws, and notifications (renotifications) to prompt the user to replace the claws are repeatedly issued at predetermined intervals until the claws are replaced.

In step S10, the judgment unit 11d checks whether the work time of the tilling tines 9 obtained from the work information storage unit 12a exceeds the tine replacement time, and if it is detected that the work time of the tilling tines 9 exceeds the tine replacement time, the process proceeds to step S11.

In step S11, the notification unit 11e on the management server 1 side notifies the worker that it is time to replace the tillage tines 9 via the display device 38 or touch panel 36 connected to the communication terminal 3 (3A, 3B) on the work vehicle side, and the process proceeds to step S12. At this time, the management server 1 may be configured to prompt the worker to replace the tillage tines 9 via the display device 38, and to display an input screen for confirming whether or not the tillage tines 9 have been replaced.

In step S12, the management server 1 checks from the replacement information recorded in the replacement information storage unit 12b whether or not the worker has replaced the tillage tines 9, and if the worker has replaced the tillage tines 9, the process proceeds to step S13.

In step S13, if the tine replacement postponement flag is set because the tiller tine replacement has been performed, the tine replacement postponement flag is reset and the process proceeds to step S14.

In step S14, the work time during which tilling work was performed using the tilling tines 9 that were most recently replaced is obtained based on the work information obtained from the work information storage unit 12a, and this is set as the latest "tine replacement time," and then the process returns.

In other words, if the tilling tines 9 are replaced for the second time or later, the tine replacement time can be set easily and with high accuracy without using the work information, as long as there is no change in the field in which the work is carried out. If there is a significant change in the conditions of the field in which the work is carried out, the replacement information (the number of times the tilling tines have been replaced) is reset, and the tine replacement time is calculated from the work information.

Incidentally, when the exchange information transmission unit 31b of the communication terminal 3 transmits the exchange information indicating that the replacement work of the tiller tines 9 has been completed to the management server 1 side via the network 2, the same exchange information is configured to be transmitted to the sales side information terminal 4 via the network 2.

Also, if in step S12 it is not detected that the tiller tines 9 are being replaced, the process proceeds to step S15, where a "tine replacement postponement (tine replacement continuation)" flag is set, and then the process returns.

Also, in step S10, if the working time (replacement time) since the tilling tines 9 were attached has not exceeded the tine replacement time, the process proceeds to step S16.

In step S16, the time until the notification by the notification unit 11, i.e., the claw replacement time, is corrected based on the updated work information obtained from the work information storage unit 12a, and then the process returns.

Also, in step S7, if this is not the first time the tiller tines 9 have been replaced (if this is the second or subsequent time the tiller tines 9 have been replaced), proceed to step S17.

In step S17, it is checked whether the claw replacement postponement flag is set, and if the claw replacement postponement flag is not checked (the claw replacement time has not elapsed), the process proceeds to step S18.

In step S18, the work information stored in the work information storage unit 12a is used to check whether there has been a change in the work time performed by the rotary tilling device 8, and if there has been a change in the work time, the process proceeds to step S19.

In step S19, if there is a change in the work time stored in the work information storage unit 12b (if tilling work is performed), the tine replacement time set when the tilling tines 9 are replaced for the second or subsequent time is corrected based on the latest work information obtained from the work information storage unit 12a, and the process proceeds to step S10.

According to this, when the tilling tines 9 are replaced for the second time or later, the tine replacement time is set based on the work time during which the tilling tines 9 that were replaced immediately before were used, but when there is a change in the work time (when tilling work is performed), this tine replacement time is corrected to match the work situation (the work information). In other words, when tilling work is performed in an environment where the tilling tines 9 are more likely to wear out, the tine replacement time is corrected to be shorter, and when tilling work is performed in an environment where the tilling tines 9 are less likely to wear out, the tine replacement time is corrected to be longer.

Also, if there is no change in the operation time of the rotary tilling device 8 in step S18, the process proceeds to step S10.

Also, if the nail replacement postponement flag is confirmed in step S17, proceed to step S20.

In step S20, it is confirmed whether a predetermined time (re-alert time) has elapsed since the notification information prompting claw replacement was transmitted by the notification unit 11e or the re-alert unit 11f until a notification prompting claw replacement is issued again, and if it is detected that the re-alert time has elapsed since the notification information prompting the most recent claw replacement was transmitted (the re-alert condition has been satisfied), the process proceeds to step S21.

In step S21, the re-notification unit 11f notifies the operator again via the display device 38 or the touch panel 36 that it is time to replace the tiller tines 9 (overtime), and the process proceeds to step S12. Note that if it is not detected in step S20 that the re-notification time has elapsed, the process proceeds to step S22.

In step S22, the re-alert time (re-alert condition) is corrected based on the newly updated work information obtained from the work information storage unit 12a, and then the process proceeds to step S12.

In other words, even if the tines are replaced for the second or subsequent times, if the management server 1 detects that a predetermined re-alert time has elapsed (the re-alert condition has been satisfied) between the time the notification urging the tiller tines 9 to be replaced and the time the tiller tines 9 are replaced, the management server 1 is configured to repeatedly issue a re-alert to urge the tiller tines 9 to be replaced via the display device 38 or the like each time the re-alert condition is satisfied.
