Conventionally, a ground improvement method by chemical solidification using a cement-based solidified material or a lime-based solidified material is known. This ground improvement method is generally classified into two types according to the depth of improvement. One is an improvement from the ground surface to around -3 m, which is called a shallow layer improvement method or a surface layer improvement method, and the other is an improvement of a portion deeper than -3 m, which is called a deep layer improvement method.

As a technique of this shallow layer improvement construction method, a boom, arm and bucket are automatically excavated by driving the boom, arm and bucket, and the rotation angle of the boom, arm and bucket is detected by an angle sensor, and the boom detected by the angle sensor is detected. It is known that the depth of the blade edge of the bucket can be calculated using the rotation angles of the arm and the bucket (for example, Patent Document 1).

In addition, as a technique for the deep layer improvement method, a drive shaft mounted on the leader mast is mounted on a drive unit that can be moved up and down, and a stirring shaft having a stirring blade is mounted, and the stirring shaft is rotated by a motor of the drive unit to excavate the ground. There is known a ground improvement machine that injects cement milk mixed with water for solid improvement for ground improvement and the like and agitates the earth and sand to improve the ground. This ground improvement machine was able to calculate the number of ground agitation per unit length of ground soil from the depth / lifting speed of the agitation head, the number of rotations of the agitation shaft, and the number of blades of the agitation head (for example, Patent Literature 2).

As described above, as a method for calculating the number of ground agitation using the depth improvement method, various management devices are attached to a dedicated machine equipped with a leader mast, and thereby a system for managing the agitation of the ground is already known. However, in the case of using the backhoe and using the backhoe and shaking the bucket attached to the backhoe to stir and mix the improved material and the local soil, the movement of the bucket is complicated. For this reason, there has been no apparatus that controls the degree of stirring and mixing by calculating the number of stirrings.

Then, the CF card 54 in which the data is stored is taken out from the management apparatus 100, and the taken out CF card 54 is inserted into the personal computer 55, and the data stored in the CF card 54 is aggregated and analyzed. The result can be output using the printer 56.

Between the cylinder bottom chamber 110a of the bucket cylinder 11 and the pilot operation switching valve 104, a flow rate for detecting the amount of oil supplied to the cylinder bottom chamber 110a of the bucket cylinder 11 and discharged from the cylinder bottom chamber 110a of the bucket cylinder 11 Detection means (flow rate sensor) 107 is provided. Then, the flow rate value of the hydraulic oil detected by the flow rate detection means 107 is sent to the management device 100, and the calculation unit 108 of the management device 100 calculates the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11. The calculation method will be described in detail. When the initial setting switch 41 is pressed , the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end), and the inside of the cylinder bottom chamber 110a of the bucket cylinder 11 in this state. Oil amount (minimum oil amount) is input in advance using the setting screen switch 39 and stored in the storage means 109. Therefore, the oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11 is the piston amount in the bucket cylinder 11 . It can be obtained by adding / subtracting the oil amount detected by the flow rate detecting means 107 to / from the oil amount in the cylinder bottom chamber 110a in the state where the rod 11a is most contracted (stroke end). Thus, in this embodiment, the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11 is detected as the amount of oil in the hydraulic oil chamber of the bucket cylinder 11.

In the present embodiment, the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11 is obtained, but not limited to this, the amount of oil in the cylinder rod chamber 11b of the bucket cylinder 11 may be obtained. In this case, the minimum oil amount is the oil amount in the cylinder rod chamber 11b in the state in which the piston rod 11a in the bucket cylinder 11 is most extended, and the oil amount in the cylinder rod chamber 11b of the bucket cylinder 11 is the bucket cylinder 11 The amount of oil detected by the flow rate detection means 107 is added to or subtracted from the amount of oil in the cylinder rod chamber 11b in the state where the inner piston rod 11a is most extended. In this case, the cylinder rod chamber 11 b of the bucket cylinder 11 is supplied between the cylinder rod chamber 11 b of the piston rod 11 a in the bucket cylinder 11 and the pilot operation switching valve 104, and from the cylinder rod chamber 11 b of the bucket cylinder 11. A flow rate detecting means (flow rate sensor) for detecting the amount of oil to be discharged is provided, and the amount of oil in the cylinder rod chamber 11b (operating oil chamber) of the bucket cylinder 11 is detected.

Next, the ground stirring step will be described with reference to FIG. FIG. 11 is a diagram illustrating a backhoe stirring step according to an embodiment of the present invention.

The operator first moves the backhoe 1 to the vicinity of the work area and stops it, and rotates the upper swing body 2 to a predetermined position so that the bucket 5 comes to the excavation work position. When the operator presses the initial setting switch 41 , the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end), and the bucket 5 is in the raised state. The oil amount (minimum oil amount) in the bucket cylinder 11 at this time is input in advance using the setting screen switch 39 as described above and stored in storage means (not shown). When the number of stirrings is measured, as described above, the stirring reference upper oil amount, the stirring reference lower oil amount (see FIG. 6), and the designed stirring number (see FIG. 7) are determined in advance on the operation panel 22 of the management apparatus 100. It is input using.

When the initial setting switch 41 is pressed by the operator, the bucket 5 is dumped, that is , the piston rod 11a in the bucket cylinder 11 of the bucket 5 is most contracted (state below the stirring reference upper oil amount). Therefore, in order to agitate the ground, first, the boom 3 and the arm 4 are pulled down so that the tip of the bucket 5 enters the ground (FIG. 11 (a)), and the tip of the bucket 5 is Once inside, the ground is stirred by rotating the boom 3, the arm 4 and the bucket 5 (FIG. 11 (b)).

Then, when the ground is excavated by the bucket 5, that is , when the piston rod 11a in the bucket cylinder 11 of the bucket 5 reaches the most extended state (a state equal to or larger than the stirring reference lower oil amount), the boom 3 and the arm 4 are moved. By pulling up, the ground is stirred, and then the bucket 5 is dumped, that is , the piston rod 11a in the bucket cylinder 11 of the bucket 5 is in the most contracted state (the state below the stirring reference upper oil amount). As a result, the earth and sand in the bucket 5 falls outside the bucket 5 (FIG. 11D). The present invention focuses on the fact that expansion and contraction of the piston rod 11a of the stirring operation and the bucket cylinder 11 of the bucket 5 (a change in oil quantity in the cylinder bottom chamber 110a) is linked, the oil in the cylinder bottom chamber 110a The number of stirrings is counted by detecting the change in the amount. Details will be described later with reference to FIGS.

Next, the relationship between the movement of the bucket 5 and the cylinder stroke position of the bucket cylinder 11 will be described with reference to FIGS. 12 and 13. FIG. 12 is an operation diagram of the bucket in one embodiment of the present invention, and FIG. 13 is a diagram showing a relationship between the movement of the bucket and the cylinder stroke position of the bucket cylinder. Since the bucket cylinder 11 has a cylindrical shape, the change in the amount of oil in the cylinder bottom chamber 110a at each cylinder stroke position of the bucket cylinder 11 also changes in proportion to the change in the cylinder stroke position.

As shown in FIG. 12, the ground is agitated as the bucket 5 moves from “1” to “10”. The cylinder stroke position of the bucket cylinder 11 corresponding to the movement of the bucket 5 ("1" to "10") is shown in FIG. The cylinder stroke position of the bucket cylinder 11 when the movement of the bucket 5 is “1” is 23% of the cylinder length of the bucket cylinder 11 (see FIG. 14), and the cylinder bottom chamber 110a of the bucket cylinder 11 at this time The amount of oil inside is also 23% of the total capacity in the bucket cylinder 11. This “1” state is a state where the piston rod 11a in the bucket cylinder 11 is most contracted (a state at the stroke end). From this state, the bucket 5 moves in the order of “1” → “2” → “3”, and the ground is stirred. When the movement of the bucket 5 becomes “6”, the cylinder stroke position of the bucket cylinder 11 is 90% of the cylinder length of the bucket cylinder 11 (see FIG. 14), and the cylinder bottom of the bucket cylinder 11 at this time The amount of oil in the chamber 110a is also 90% of the total capacity in the bucket cylinder 11. The state “6” is a state in which the piston rod 11a in the bucket cylinder 11 is most extended. As the state proceeds from the “6” state to the “10” state, the piston rod 11a in the bucket cylinder 11 gradually contracts, and the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11 also decreases. In this way, one stirring operation of the bucket 5 is performed.

Next, a method for measuring the number of times of stirring will be described in detail with reference to FIGS. FIG. 15 is a flowchart of the agitation number process in one embodiment of the present invention.

First, in S11, it is determined whether the power is “ON”. Whether or not the power is “ON” is determined by whether or not the power switch 25 (see FIG. 5) is pressed. If “NO” in S11, the process is ended and the number of stirring processes is executed again. If “YES”, the process proceeds to S12.

Next, in S12, it is determined whether the start / end button is “ON”. Whether or not the start / end button is “ON” is determined by whether or not the start / end switch 23 (see FIG. 5) has been pressed. If “NO” in S12, the process is terminated and the number of stirring processes is executed again. If “YES”, the process proceeds to S13.

In S13, it is determined whether a screen setting condition is input. The screen setting condition is input using the setting screen switch 39 (FIG. 6). Whether or not this screen setting condition is input depends on the length of the boom 3, the length of the arm 4, the stirring reference upper oil amount and the stirring reference lower oil amount of the bucket cylinder 11, and the minimum oil amount of the bucket cylinder 11. Judgment is made based on whether or not everything has been input. If “NO” in S13, the process proceeds to S132, and it is notified that the screen setting condition is not input by S132 (notification means (buzzer or sound) “ON”), and until the screen setting condition is input, S13 → The processing from S132 to S13 is repeated. When the screen setting condition is input (“YES” in S13), the process proceeds to S133, the notifying unit is turned “OFF” in S133, and the processing flag SS is set to “0” in S134. This in-process flag SS is a flag that becomes “1” when the stirring number measurement process is being executed. Then, the measured values 34a, 35a, 36a, 37 are reset by S14 (see FIG. 6). As a result, the measured values 34a, 35a, 36a, and 37 all become “0 times”.

  In S15, measurement flag processing is executed. By this measurement flag process, it is determined which of the first to third layers is to be measured. The measurement flag process will be described later with reference to FIG.

  In S16, a stirring number measurement process is executed. The number of stirrings is measured by this stirring number measuring process. The stirring number measurement process will be described later with reference to FIG.

In S17, it is determined whether the start / end button 23 is “OFF”. Whether the start / end button 23 is “OFF” is determined by whether the start / end button 23 is pressed again when the start / end button 23 is “ON”. If “NO” is determined in S17, the process proceeds to S18. In S18, it is determined whether the interruption / resumption switch 24 is “ON”. If “NO” is determined in S18, “YES” is determined in S17. Until it is determined, the process of S15 → S16 → S17 → S18 → S15 is executed. If “YES” is determined in S18, the processes of S17 → S18 → S17 are executed until “NO” is determined in S18. If it is determined “YES” in S <b> 17, the stirring number process ends and the stirring number process is executed again. Thereby, the frequency | count of stirring is measured.

Next, the measurement flag process, which is a subroutine for the stirring number process, will be described with reference to FIG. FIG. 16 is a diagram showing a measurement flag process that is a subroutine of the stirring number process. This measurement flag process is for deciding which of the first to third layers is to be measured.

First, in S21, it is determined whether the three-layer stirring frequency switch is “ON”. Whether or not the three-layer stirring number switch is “ON” is determined by whether or not the three-layer stirring number switch 36 (see FIG. 6) is pressed. If “YES” is determined in S21, the process proceeds to S22, and the three-layer measurement flag is turned “ON” in S22. When the three-layer measurement flag is “ON”, the number of stirrings is measured as a measurement value of the number of three-layer stirrings (see FIG. 6). If “NO” is determined in S21, the process proceeds to S23.

In S23, it is determined whether the two-layer stirring frequency switch is “ON”. Whether or not the two-layer stirring number switch is “ON” is determined by whether or not the two-layer stirring number switch 35 (see FIG. 6) is pressed. If “YES” is determined in S23, the process proceeds to S24, and the two-layer measurement flag is turned “ON” in S24. When the two-layer measurement flag is “ON”, the number of stirrings is measured as a measured value of the number of two-layer stirrings (see FIG. 6). If “NO” is determined in S23, the process proceeds to S25.

In S25, it is determined whether or not the one-layer stirring frequency switch is “ON”. Whether or not this one-layer stirring number switch is “ON” is determined by whether or not the one-layer stirring number switch 34 (see FIG. 6) is pressed. If “YES” is determined in S25, the process proceeds to S26, and the one-layer measurement flag is turned “ON” in S26. When this one-layer measurement flag is set to “ON”, the number of times of stirring is measured as a measured value of the number of times of one-layer stirring (see FIG. 6). If “NO” is determined in S25, the notification means (buzzer, lamp, etc. (not shown)) is turned “ON” in S27, and the process proceeds to S21 again, and the one-layer stirring number switch 34 to the three-layer stirring number Until one of the switches 36 is pressed, the process of S21 → S23 → S25 → S27 → S21 is executed. If “YES” is determined in any of S21, S23, or S25, the processing of S22, S24, or S26 is executed, and the notification unit is set to “OFF” in S28, and the measurement flag processing ends.

Next, the stirring number measurement process which is a subroutine of the stirring number process will be described. FIG. 17 is a diagram showing a stirring number measurement process that is a subroutine of the stirring number process. The number of stirrings is measured by this stirring number measuring process.

First, in S30, it is determined whether or not the processing flag SS is “1”. Since this processing flag SS is set to “0” in S134 (see FIG. 15), it is determined as “NO” in S30, and the process proceeds to S31. As described above, the processing flag SS is a flag that is “1” when the stirring number measurement processing is being executed.

In S31, it is determined whether the number of times of stirring N is “0”. If it is determined “YES” in S31, the process proceeds to S32. If it is determined “NO”, the process proceeds to S36. Then, in S32, it is determined whether initial setting has been performed. Whether or not the initial setting is performed is determined by pressing the initial setting switch 41 to bring the bucket 5 into the initial setting position, that is , the piston rod 11a in the bucket cylinder 11 is most contracted (stroke end state). It is judged by whether it is. If “NO” is determined in S32, the process proceeds to S33, where it is notified that the initial setting condition is not input (notification means (buzzer or sound) “ON”), and the initial setting condition is input. Until this is done, the processing of S32 → S33 → S32 is repeatedly executed. Note that the setting screen switch 39 is used for the oil amount (minimum oil amount) in the cylinder bottom chamber 110a of the bucket cylinder 11 when the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end state). And stored in a storage means (not shown). If the initial setting condition is input in S32, the process proceeds to S34. If the notification means is “ON”, the notification means is turned “OFF”, and the position flag F1 is set to “1” in S35. The processing flag SS is set to “1”. The position flag (FI) is a flag for switching whether to determine the stirring reference lower oil amount or the stirring reference upper oil amount.

Next, in S36, it is determined whether the position flag FI is “1”. Since the position flag FI is set to “1” in S35, “YES” is determined in S36, and the process proceeds to S37. In S37, the bucket cylinder oil amount (the oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11) is detected (measured). The amount of oil in the bucket cylinder is the amount of oil in the cylinder bottom chamber 110a (minimum amount of oil) when the initial setting switch 41 is pressed and the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end state). ) Is input in advance using the setting screen switch 39 and stored in the storage means 109. Therefore, the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11 is most contracted by the piston rod 11a in the bucket cylinder 11. It can be obtained by adding or subtracting the oil amount detected by the flow sensor (flow rate detecting means) 107 to the oil amount in the cylinder bottom chamber 110a in the state (stroke end state).

In S38, it is determined whether the bucket cylinder oil amount detected in S37 is larger than the stirring reference lower oil amount. The stirring reference lower oil amount is input in advance by pressing the setting screen switch 39. In the present embodiment, the oil amount corresponding to 80% of the total volume in the bucket cylinder 11 is set as the stirring reference lower oil amount. If “YES” is determined in S38, the position flag FI is set to “2” in S39, and the agitation count measurement process is completed. If “NO” is determined in S38, the agitation is continued. The count measurement process ends. Then, as described above with reference to FIG. 15, the stirring number measurement process is executed again until the start / end switch 23 is turned “OFF” (S17 → S18 → S15 → S16 (see FIG. 15)). If “NO” is determined in S38, the processes of S17 → S18 → S15 → S30 → S36 → S37 → S38 → S17 are repeatedly executed until the bucket cylinder oil amount becomes larger than the stirring reference lower oil amount. (See FIGS. 15 and 17). In this way, in the stirring count measurement process to be executed again, “NO” is determined in S30 (the processing flag SS is set to “1” in S35), and the process proceeds to S36. Thus, in this embodiment, the stirring reference lower oil amount corresponds to the stirring reference other end oil amount, and the stirring reference upper oil amount corresponds to the stirring reference one end oil amount.

In this embodiment, since the bucket cylinder oil amount is the oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11, it is determined in S38 whether the bucket cylinder oil amount detected in S37 is larger than the stirring reference lower oil amount. If it is determined that the bucket cylinder oil amount is the oil amount in the cylinder lot chamber 11b of the bucket cylinder 11, whether or not the bucket cylinder oil amount detected in S37 is smaller than the stirring reference lower oil amount in S38 (bucket The cylinder oil amount <the stirring reference lower oil amount) will be judged.

Next, in S36, it is determined whether the position flag FI is “1”. Since the position flag FI is set to “2” in S39, “NO” is determined in S36, and the process proceeds to S40. In S40, the bucket cylinder oil amount (the oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11) is detected (measured). Since the method for detecting the bucket cylinder oil amount is the same as that in S37, the description thereof is omitted.

In S41, it is determined whether the bucket cylinder oil amount detected in S40 is smaller than the stirring reference upper oil amount. This stirring reference upper oil amount is input in advance by pressing the setting screen switch 39. In the present embodiment, an oil amount corresponding to 30% of the total volume in the bucket cylinder 11 is set as the stirring reference upper oil amount. If “YES” is determined in S41, a stirring number counting process is executed in S42. In this stirring number counting process, the number of stirring times is counted. Details of the stirring number counting process will be described later with reference to FIG. If “YES” is determined in S41, the position flag FI is set to “1” in S39, and the stirring number measurement process is completed. If “NO” is determined in S41, the stirring is performed as it is. The count measurement process ends. Then, as described above with reference to FIG. 15, the stirring number measurement process is executed again until the start / end switch 23 is turned “OFF” (S17 → S18 → S15 → S16 (see FIG. 15)). If “NO” is determined in S41, the process of S17 → S18 → S15 → S30 → S36 → S40 → S41 → S17 is repeatedly executed until the bucket cylinder oil amount becomes smaller than the stirring reference upper oil amount. (See FIGS. 15 and 17).

Next, the stirring number counting process, which is a subroutine of the stirring number measuring process, will be described. FIG. 18 is a diagram showing a stirring number counting process which is a subroutine of the stirring number measuring process. By this stirring number counting process, the number of stirring times is counted.

First, in S51, “1” is added to the number of times of stirring (N). Here, the number of times of stirring (N) is the sum of the number of times of stirring (N1 to N3).

Next, in S52, it is determined whether the three-layer measurement flag is “ON”. The three-layer measurement flag is “ON” when the three-layer stirring number switch 36 (see FIG. 6) is pressed (S21 (FIG. 16)). If “YES” is determined in S52, the process proceeds to S53, and “1” is added to the number of agitation (N3) in S53, and the agitation number counting process ends. If “NO” is determined in S52, the process proceeds to S54.

Next, in S54, it is determined whether the two-layer measurement flag is “ON”. This two-layer measurement flag is “ON” when the two-layer stirring number switch 35 (see FIG. 6) is pressed (S23 (FIG. 16)). If “YES” is determined in S54, the process proceeds to S55, and the stirring number (N2) is incremented by “1” in S55, and the stirring number counting process is ended. If “NO” is determined in S54, the process proceeds to S56.

Next, in S56, it is determined whether the first layer measurement flag is “ON”. This one-layer measurement flag is “ON” when the one-layer stirring number switch 34 (see FIG. 6) is pressed (S25 (FIG. 16)). If “YES” is determined in S56, the process proceeds to S57. In S57, “1” is added to the number of stirrings (N1), and the stirring number counting process ends. If “NO” is determined in S56, the process proceeds to S52 again. And the process of S56-> S52-> S54-> S56 is performed until either of S52, S54, or S56 becomes "ON", and if it becomes "ON", the number of stirring of any one of the first to third layers is set. “1” is added, and the stirring number counting process ends.

The number of stirrings (N1, N2, N3, N) is added by the stirring number counting process, and the notification means (when the added number of stirrings reaches the design value (34b, 35b, 36b, 38)) You may make it notify to a buzzer, a lamp, etc.). In this way, the operator can know that the number of times of stirring (N1, N2, N3, N) has reached the design value (34b, 35b, 36b, 38), and the number of times the worker wants to stir in advance. Only accurately and reliably can be stirred. In this case, the sound of the buzzer (notification means) may be varied or the color of the lamp (notification means) may be varied depending on the number of times of stirring (N1, N2, N3, N).

In this embodiment, the bucket cylinder oil amount (the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11) is changed from the stirring reference upper oil amount (stirring reference one end oil amount) to the stirring reference lower oil amount (stirring reference other end oil). The amount of stirring is counted when the stirring reference lower oil amount (stirring reference other end oil amount) becomes the stirring reference upper oil amount (stirring one end oil amount). However, the bucket cylinder oil amount (oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11) is substantially changed from the stirring reference lower oil amount (stirring reference other end oil amount) to the stirring reference upper oil amount (one stirring reference one end). It can be said that the number of agitation is counted when the amount of oil is reached.

(Second Embodiment)
Next, the management system of the stirring and mixing apparatus in the second embodiment of the present invention will be described.
In addition, about the structure same as the management system of the stirring and mixing apparatus in 1st Embodiment, the same code | symbol is used and the same effect is demonstrated and description is abbreviate | omitted.

  The difference between the management system of the stirring and mixing apparatus of the second embodiment of the present invention and the management system of the stirring and mixing apparatus of the first embodiment is that the amount of oil in the bucket cylinder is used in the management system of the stirring and mixing apparatus of the first embodiment. The number of times of agitation was counted by determining whether the oil amount was larger than the agitation reference lower oil amount or smaller than the agitation reference upper oil amount. In the management system for the agitation and mixing device of the second embodiment, the bucket cylinder The cylinder stroke position of the bucket cylinder 11 (see FIG. 19) is obtained instead of the oil amount, and it is determined whether the cylinder stroke position is larger than the stirring reference lower position or smaller than the stirring reference upper position, and the number of stirring is counted. I'm about to do it.

In the management system for the stirring and mixing apparatus of the second embodiment, the boom screen, the arm length, the stirring reference upper position and the stirring reference lower position of the bucket cylinder 11, and the minimum position of the bucket cylinder 11 are set by the setting screen switch 39 of FIG. Can be entered. In this embodiment, the stirring reference upper position, the stirring reference lower position, and the minimum position are input in units of “cm”. However, instead of inputting in “cm” units, what percentage of the total volume of the bucket cylinder 11 may be input in “%” units (see FIG. 19). Note that when the input is performed in units of “%”, the calculation unit 108 of the management apparatus 100 calculates how many cm the position of the input “%” unit corresponds to. For example, when the stirring reference upper position is 30% of the total volume of the bucket cylinder 11 and the stirring reference lower position is 80% of the total volume of the bucket cylinder 11, the stirring reference upper position is “0.3 × cylinder”. The stirring reference lower position is calculated as “0.8 × cylinder length” (see FIG. 19). Here, the minimum position of the bucket cylinder 11 is the cylinder stroke position of the bucket cylinder 11 when the piston rod 11a in the bucket cylinder 11 is most contracted (at the stroke end).

In the present embodiment , the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end state) by pressing the initial setting switch 41. 11 is input, but the present invention is not limited to this . If the piston rod 11a in the bucket cylinder 11 is in the most extended state by pressing the initial setting switch 41, the setting screen switch The maximum position of the bucket cylinder 11 may be input by 39. The maximum position of the bucket cylinder 11 is the cylinder stroke position of the bucket cylinder 11 when the piston rod 11a in the bucket cylinder 11 is most extended.

The initial setting switch 41 is a switch for setting the bucket 5 to the initial setting position. When the initial setting switch 41 is pressed , the piston rod 11a in the bucket cylinder 11 is most contracted (stroke end state ). to become. As described above, the cylinder stroke position (minimum position) of the bucket cylinder 11 when the piston rod 11a in the bucket cylinder 11 is most contracted is input by using the setting screen switch 39 to store the storage means ( (Not shown).

Moreover, in the operation panel 19 of FIG. 6, instead of the stirring reference upper oil amount display part 42a, the stirring reference lower oil amount display part 42b, and the bucket cylinder oil amount display part 42c of the first embodiment. An agitation reference upper position display part 42a, an agitation reference lower position display part 42b, and a bucket cylinder position display part 42c are provided. The agitation reference upper position display part 42a and the agitation reference lower position display part 42b display the agitation reference upper position and the agitation reference lower position input using the setting screen switch 39, and the bucket cylinder position display part 42c. Indicates the current cylinder stroke position of the bucket cylinder 11. Here, as will be described later, when the position displayed on the bucket cylinder position display section 42c is equal to or higher than the stirring reference lower position, the lamp next to the stirring reference lower position display section 42b flashes, and then the bucket cylinder position display section When the position displayed on 42c becomes equal to or lower than the stirring reference upper position, the lamp next to the stirring reference lower position display section 42b is turned off and the lamp next to the stirring reference upper position display section 42a blinks. Then, similarly, the lamps beside the stirring reference lower position display unit 42b and the stirring reference upper position display unit 42a are turned off / flashing. Thereby, the worker can grasp whether the bucket 5 is currently moving in the direction of dumping or moving in the direction of excavation.

The current cylinder stroke position of the bucket cylinder 11 is calculated by the calculation unit 108 of the management device 100 by sending the flow rate value of the hydraulic oil detected by the flow rate detection means (flow rate sensor) 107 to the management device 100. The calculation method will be described in detail. When the initial setting switch 41 in FIG. 6 is pressed , the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end state). Since the cylinder stroke position (minimum position) is input in advance using the setting screen switch 39 of FIG. 6 and stored in the storage means 109, the cylinder stroke position of the bucket cylinder 11 is determined by the piston rod 11a in the bucket cylinder 11 . most contracted state cylinder stroke oil amount detected by the flow rate detection means 107 to the position ( "g" convert the units to "cm ^3") and divided by the cylinder diameter (cm ²⁾ of the (stroke end state) Can be obtained by adding and subtracting.

In this embodiment, the cylinder stroke position (see FIG. 19) is obtained from the cylinder bottom chamber 110a side of the bucket cylinder 11. However, the present invention is not limited to this, and the cylinder stroke position is obtained from the cylinder rod chamber 11b side of the bucket cylinder 11. It is good as well. In this case, the minimum position is the cylinder stroke position obtained from the cylinder rod chamber 11b side where the piston rod 11a in the bucket cylinder 11 is most extended, and the cylinder stroke position obtained from the cylinder rod chamber 11b side of the bucket cylinder 11 The oil amount detected by the flow rate detection means 107 (converted from “g” to “cm ³ ”) at the cylinder stroke position where the piston rod 11a in the bucket cylinder 11 is most extended is converted into the cylinder diameter (cm ^2). ) Is obtained by adding and subtracting the value divided by. In this case, the amount of oil supplied to the cylinder rod chamber 11b of the bucket cylinder 11 and discharged from the cylinder rod chamber 11b of the bucket cylinder 11 between the cylinder rod chamber 11b of the bucket cylinder 11 and the pilot operation switching valve 104. The flow rate detecting means 107 (flow rate sensor) for detecting the oil amount is provided, and the amount of oil in the cylinder rod chamber 11b (operating oil chamber) of the bucket cylinder 11 is detected.

Next, the stirring number measurement process that is a subroutine of the stirring number process in the second embodiment will be described. FIG. 20 is a diagram showing a stirring number measurement process which is a subroutine of the stirring number process in the second embodiment of the present invention. The number of stirrings is measured by this stirring number measuring process. In addition, about the stirring frequency measurement process of FIG. 20, only the different part of the stirring frequency measurement process of FIG. 17 is demonstrated, and since others are the same as the stirring frequency measurement process of FIG. 17, description is abbreviate | omitted.

In S337 and S340, the bucket cylinder position (the stroke position of the bucket cylinder 11) is detected. The bucket cylinder position is detected as follows. That is, in S32 , the piston rod 11a in the bucket cylinder 11 is in the most contracted state (stroke end state), and the cylinder stroke position (minimum position) of the bucket cylinder 11 in this state is set using the setting screen switch 39. Since it is inputted in advance (S13) and stored in the storage means 109, the cylinder stroke position of the bucket cylinder 11 is the cylinder stroke position when the piston rod 11a in the bucket cylinder 11 is most contracted (stroke end state). The value obtained by adding and subtracting the value obtained by dividing the bucket cylinder oil amount (oil amount (cm ³ ) in the cylinder bottom chamber 110a of the bucket cylinder 11) by the cylinder diameter (cm ² ) detected by the flow rate detection means 107 is obtained. it can.

In S338, it is determined whether the bucket cylinder position detected in S337 is larger than the stirring reference lower position. This stirring reference lower position is input in advance by pressing the setting screen switch 39. In the present embodiment, the cylinder stroke position (cm) corresponding to 80% of the total volume in the bucket cylinder 11 is set as the stirring reference lower position. Thus, in the second embodiment, the stirring reference lower position corresponds to the stirring reference other end position, and the stirring reference upper position corresponds to the stirring reference one end position.

In S341, it is determined whether the bucket cylinder position (stroke position of the bucket cylinder 11) detected in S340 is smaller than the stirring reference upper position. This stirring reference upper position is input in advance by pressing the setting screen switch 39. In this embodiment, the cylinder stroke position (cm) corresponding to 30% of the total volume in the bucket cylinder 11 is set as the stirring reference upper position.

In this embodiment, the cylinder stroke position of the bucket cylinder 11 changes from the stirring reference upper position (stirring reference one end position) to the stirring reference lower position (stirring reference other end position), and further the stirring reference lower position (stirring reference other end). In this example, the number of times of agitation is counted when the agitation reference upper position (the agitation reference one end position) is changed to the agitation reference upper position, but the cylinder stroke position of the bucket cylinder 11 is substantially the agitation reference lower position. It can be said that the number of times of stirring is counted when the stirring reference upper position (stirring reference one end position) is changed from (stirring reference other end position).

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

Although the description has been made so that the number of times of agitation is counted when the oil amount reaches one end), the present invention is not limited to this, and the bucket cylinder oil amount (the oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11) is the agitation reference upper oil amount. You may make it count the frequency | count of stirring, when it becomes the stirring reference lower part oil amount (stirring reference one end oil amount) from (the stirring reference other end oil amount).

(2) In this embodiment, the bucket cylinder oil amount (the amount of oil in the cylinder bottom chamber 110a of the bucket cylinder 11) is changed from the stirring reference upper oil amount (stirring reference one end oil amount) to the stirring reference lower oil amount (stirring reference etc. Explains that the number of times of agitation is counted when the amount of oil at the end is changed, and the amount of oil at the lower end of the agitation reference (oil amount at the other end of the agitation reference) is changed from the amount of oil at the upper end of the agitation reference However, the present invention is not limited to this, and the bucket cylinder oil amount (oil amount in the cylinder bottom chamber 110a of the bucket cylinder 11) is changed from the stirring reference lower oil amount (stirring reference one end oil amount) to the stirring reference upper oil amount (stirring reference etc. When the oil amount reaches the end oil amount), and the stirring reference upper oil amount (the oil amount at the other end of the stirring reference) changes to the oil reference lower oil amount (the oil amount at the one end of the stirring reference), the number of times of stirring is counted. Also good.

(3) In this embodiment, the number of times of stirring is counted when the cylinder stroke position of the bucket cylinder 11 changes from the stirring reference lower position (stirring reference other end position) to the stirring reference upper position (stirring reference one end position).

Although the description has been made so that the number of times of stirring is counted when the stirring reference upper position (stirring reference one end position) is changed from the reference other end position), the cylinder stroke position of the bucket cylinder 11 is not limited to this. From the position (stirring reference one end position) to the stirring reference upper position (stirring reference other end position), and further from the stirring reference upper position (stirring reference other end position) to the stirring reference lower position (stirring reference one end position) When it becomes, you may make it count the frequency | count of stirring.

Not only agitation but also other operations such as movement of earth and sand may be performed. Moreover, since the management apparatus 100 and the angle sensors 12 and 13 are provided in the backhoe 1 so that attachment or detachment is possible, the management apparatus 100 and the angle sensors 12 and 13 can be used not only for other similar backhoes 1 but also for different types of backhoes 1. Can also be easily installed. The measurement of the number of times of stirring can also be applied to a management system for a stirring and mixing device that does not use the angle sensors 12 and 13.

(7) The method for obtaining the cylinder stroke position in the second embodiment may be as follows (see, for example, JP-A-2007-333628). That is, a magnetic force sensor as a cylinder stroke sensor is provided outside the cylinder tube which is a cylinder wall, and a magnet for generating a magnetic force line is provided for the piston. A pole and an S pole are provided. The magnetic force sensor is composed of two magnetic force sensors arranged at a predetermined distance along the direction of linear movement of the piston. The magnetic force sensor transmits a magnetic force line generated by the magnet to generate a magnetic force (magnetic flux density). ) And an electric signal (voltage) S corresponding to the magnetic force (magnetic flux density) is output. Based on the detection result of the magnetic sensor, the measurement position obtained from the detection result of the rotation sensor is reset to the origin position (reference position). In this manner, the controller calculates the stroke position of the piston by calculating the detection signal of the magnetic sensor and the detection signal of the rotation sensor.

  In this embodiment, the angle sensor is used. However, it is not necessary to use the angle sensor for counting the number of times of stirring, and the present invention does not use the angle sensor.
