Description

  The present invention relates to a soil improvement machine suitably used to add a soil improvement material to soil such as soft ground or excavation sites, and a method for correcting the supply amount of the soil improvement material.

  In general, a soil conditioner is a machine that adds various types of soil conditioner to the soil and mixes them.For example, the soil that is used to reinforce the soft ground when performing foundation work, or to backfill the excavation site. It is used to improve to an appropriate soil quality (see, for example, Patent Document 1).

JP 2001-32263 A

  This kind of conventional soil improvement machine includes a hopper into which soil is introduced, a transport conveyor for transporting the soil put into the hopper, and a soil improvement to supply soil improvement material to the soil transported by the transport conveyor. The material supply device, a mixing device that mixes the earth and sand transported by the transport conveyor and the soil quality improving material to generate improved soil, and a discharge conveyor that discharges the improved soil generated by the mixing device. ing.

  In addition, the soil improvement material supply device includes a storage portion formed as a container for storing the soil improvement material, and is attached to the storage portion and rotated by a motor or the like to transfer the soil improvement material in the storage portion onto the conveyor. And an impeller-like rotor to be supplied to the motor. Then, the supply device adds and supplies an amount of soil quality improving material corresponding to the number of rotations of the rotor to the soil transported by the transport conveyor, and the soil and the soil quality improving material are agitated by the mixing device. It will be improved soil.

Here, the addition rate of the soil improvement material is set in advance as the weight of the soil improvement material to be mixed with a certain amount of soil, for example, several percent with respect to the weight of the soil or several hundred kg with respect to 1 m ³ of the soil. It is often done. The weight of the soil improvement material added to the earth and sand when the rotor makes one revolution is calculated as, for example, the product of the volume per rotation of the rotor, the rotational speed of the rotor, and the specific gravity of the soil improvement material. can do.

  For this reason, in the prior art, when adding the soil improvement material, for example, while measuring the weight or volume of the earth and sand transported by the transport conveyor, the weight of the improved soil discharged from the discharge conveyor is measured, and the difference between these is measured. Thus, the amount of the soil improvement material used by adding to the earth and sand is calculated, and the rotational speed of the rotor is controlled so that both have a predetermined mixing ratio.

  In this case, as another conventional technique, for example, the amount of soil transported (processed amount) and the calculated amount of soil improvement material used added to the soil are output as daily work reports. An improved machine is also known (see, for example, Patent Document 2).

JP 2003-64718 A

  By the way, in the prior art of patent document 1 mentioned above, it is set as the structure which adjusts the usage-amount of a soil improvement material by controlling the rotation speed of a rotor. In this case, a plurality of partition walls are provided on the outer peripheral side of the rotor, and a plurality of spaces into which the soil improvement material enters when the rotor rotates are defined between the partition walls. For example, when the specific gravity of the soil improvement material is stable and the rotor is rotating at a low speed, the soil improvement material having a constant weight enters each space of the rotor every time the rotor rotates once. Sent out. Therefore, the weight of the soil improvement material used in addition to the earth and sand is proportional to the volume of the space in which the soil improvement material enters when the rotor rotates once, the number of rotations, and the specific gravity of the soil improvement material. It almost matches the above value.

  However, when the rotor is rotating at a relatively high speed, for example, the rotor rotates before a sufficient amount of soil improving material is filled in each space of the rotor. The amount of material tends to decrease compared to when rotating at low speed. In addition, when a large amount of soil improvement material is accommodated in the supply device, the amount of the soil improvement material that enters the space may increase due to its weight. That is, depending on the working conditions, the filling rate of the soil improvement material entering the space of the rotor may increase or decrease, and depending on the storage condition (accommodation amount, etc.) of the soil improvement material stored in the soil improvement material supply device, the space Variations may occur in the specific gravity of the soil quality improving material filled therein.

  For this reason, in the prior art of patent document 1, it becomes easy to produce an error between the calculation supply amount of the soil improvement material calculated according to the rotation speed of a rotor, and an actual supply amount, and the conveyance amount of earth and sand. Even if the rotational speed of the rotor is controlled according to the above, there is a problem that it is difficult to stabilize the mixing ratio of the soil conditioner.

  Moreover, in the prior art of patent document 2, the calculation usage-amount of a soil improvement material is output as a work daily report. However, even in this case, for the same reason as in Patent Document 1, an error is likely to occur in the calculation value of the usage amount. There is a problem that it is difficult to grasp the mixing ratio.

  The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to accurately use the amount of soil improvement material even when, for example, the operating state of the supply device or the specific gravity of the soil improvement material varies. It is an object of the present invention to provide a soil improvement machine capable of grasping and stably mixing earth and sand and a soil improvement material at a desired ratio and a method for correcting the supply amount of the soil improvement material.

When replenishing the soil improvement material supply device, the amount of use is calculated using the number of revolutions of the soil improvement material supply device, and the input value of the replenishment amount and the calculated value of the use amount when replenished last time are calculated. The configuration is used to calculate the correction coefficient of the usage amount.

According to a second aspect of the present invention, there is provided a remaining amount sensor for detecting that the soil quality improving material accommodated in the soil quality improving material supply device has decreased to the certain remaining level to be replenished.

According to a third aspect of the present invention, there is provided a notifying means for notifying that the soil quality improving material housed in the soil quality improving material supply device has been reduced to the certain remaining level to be replenished.

Further, according to the invention of claim 4, the soil improvement agent supply apparatus is configured to replenish the soil improvement agent from the external reservoir, the soil improvement agent supply apparatus of the constant soil improvement agent which is accommodated to be supplied to the A signal output means is provided for outputting a signal instructing replenishment to the external storage when the remaining level is reduced.

On the other hand, in the invention of claim 5, a hopper into which earth and sand to be improved in soil quality are charged, a conveying device for conveying the earth and sand charged into the hopper, and a soil improvement material replenished from an external storage are accommodated and conveyed. A soil improvement material supply device that supplies the soil improvement material to the soil transported by the device, a mixing device that generates the improved soil by mixing the soil and the soil improvement material transported by the transport device, and the mixing A soil quality improvement material supply amount correction method for a soil improvement machine comprising a discharge device for discharging the improved soil generated by a device, wherein the soil quality improvement material replenished to the soil quality improvement material supply device from the external storage the replenishment amount is metered by metering means, said calculating the amount of soil improvement agent supply apparatus soil improvement agent used in the previous and the replenishment amount of soil improvement agent when the previously supplementation is metered by said metering means And the use amount of the calculated soil improvement agent displayed by the display means, the soil improvement agent supplied from the soil improvement agent supply apparatus by the calculated value of the metric value and the amount of replenishment amount when the last replenishment The configuration is such that the actual supply amount is corrected, the soil improvement material supply device is rotated by a drive source, and the soil improvement material in the soil improvement material supply device reaches a certain remaining level, and the soil improvement material is When replenishing the soil improvement material supply device, the amount of use is calculated using the number of revolutions of the soil improvement material supply device, and the measured value of the replenishment amount and the calculated value of the use amount when replenished last time are calculated. It is set as the structure which calculates the correction coefficient of the said usage-amount using.

According to the invention of claim 1, the replenishment amount of the soil improvement material can be input to the replenishment amount input means. In addition, while calculating the usage amount of the soil improvement material by the usage amount calculation means, the earth and sand and the soil improvement material can be mixed at a predetermined ratio according to the calculation result. Then, when the soil improvement material in the soil improvement material supply device is reduced to a certain remaining level and the soil improvement material is supplied to the soil improvement material supply device, the display means is the previous time input to the supply amount input means. It is possible to display the replenishment amount when replenished and the calculated use amount calculated by the use amount calculating means while the soil supply material for this replenishment amount is used.

Thereby, the worker who performs the soil improvement work can easily check, for example, the replenishment state, the use state, the remaining amount, etc. of the soil improvement material by the display means. And when the contents of the replenishment amount and the usage amount when replenished last time are different, it is possible to quickly grasp that the calculation accuracy of the usage amount has decreased, and for example, the calculation accuracy of the usage amount can be increased by correction or the like. . Therefore, for example, even when the operating condition of the soil improvement material supply device, the specific gravity of the soil improvement material, and the like fluctuate, it is possible to reliably prevent an excessive supply or supply shortage of the soil improvement material due to an error in the calculation of the usage amount. be able to. In this way, when replenishing soil improvement material to the soil improvement material supply device, the replenishment amount and use amount when the soil improvement material was replenished last time can be easily confirmed, and the mixing ratio is stabilized to improve the quality. Soil can be generated efficiently.

Thus , according to the first aspect of the present invention, when the soil quality improving material in the soil quality improving material supply device reaches a certain remaining amount level and replenishes the soil quality improving material, the usage amount calculating means is the soil quality improving material. The amount of use of the soil conditioner can be calculated using the rotational speed of the supply device. In this case, the calculated value of the usage amount should be equal to the input value of the replenishment amount at the previous replenishment. Therefore, the correction coefficient can be calculated by comparing them, and the usage amount can be corrected using this correction coefficient. Therefore, it is possible to improve the calculation accuracy of the usage amount.

According to the invention of claim 2, the remaining amount sensor is, for example, a constant to be replenished by the soil improvement material by measuring the weight, volume, remaining amount level, etc. of the soil improvement material accommodated in the supply device. It is possible to reliably detect the reduction to the remaining amount level , and to set this detection time as the replenishment timing of the soil improvement material. As a result, when it becomes the replenishment timing of the soil improvement material, the input value of the replenishment amount input to the replenishment amount input means at the previous replenishment timing and the soil improvement used from the previous replenishment timing to the current replenishment timing Since the calculated usage of the material should be equal, by comparing these values at each replenishment timing, the usage can be corrected at short intervals and the calculation accuracy can be checked periodically. .

  For example, when using a correction coefficient for the usage amount, a new correction coefficient can be calculated at each replenishment timing, so that the correction coefficient is always set to an appropriate value even when the calculation accuracy of the usage amount varies with time, for example. It is possible to update, and it is possible to reliably prevent the calculated usage amount from deviating greatly from the actual supply amount.

According to the invention of claim 3, when the soil conditioner in the supply device is reduced to a certain remaining level to be replenished, this state can be notified to surrounding workers and the like by the notification means. As a result, it is possible to prevent variations in replenishment timing, forgetting replenishment, and the like, and to perform replenishment work stably.

According to the fourth aspect of the present invention, when the soil conditioner in the supply device is reduced to a certain remaining level to be replenished, the signal output means can be operated according to the detection signal of the remaining amount sensor. For example, it is possible to output a signal instructing the external storage such as a silo to replenish the soil improvement material. As a result, the soil conditioner supply device can automatically replenish the soil conditioner from the external storage at the time of replenishment. The replenishment work can be performed unmanned and efficiently.

On the other hand, according to the invention of claim 5 , the soil conditioner supply device can be efficiently replenished with a predetermined amount of soil conditioner from the external storage at every replenishment timing, for example. The replenishment amount of soil improvement material can be measured. Moreover, the calculation usage of the soil improvement material supplied to the soil from the soil improvement material supply device can be calculated, and the soil and the soil improvement material can be mixed at a predetermined ratio according to the calculation result. .

In this case, the display means can display the replenishment amount of the soil quality improvement material when it was replenished last time measured by the weighing means and the calculated use amount calculated while the soil supply material for this replenishment amount is used. , When the contents of the replenishment amount and the amount used in the previous replenishment are different, it is possible to quickly grasp that the calculation accuracy of the amount used has been reduced, and the actual amount of soil improvement material supplied according to the result of the calculation (Use amount) can be corrected. Therefore, for example, even when the operating condition of the soil improvement material supply device, the specific gravity of the soil improvement material, and the like fluctuate, it is possible to reliably prevent an excessive supply or supply shortage of the soil improvement material due to an error in the calculation of the usage amount. be able to. Thus, the replenishment amount and the use amount when the soil quality improving material was replenished last time can be easily confirmed, and the mixing ratio can be stabilized and the high quality improved soil can be efficiently generated.

Furthermore, according to the invention of claim 5, for example, the soil improvement material for the replenishment amount measured by the measuring means can be replenished from the external storage, so that the replenishment work can be performed efficiently. And in this replenishment timing, the usage-amount in calculation of the soil improvement material used between the last replenishment timing and this replenishment timing can be calculated. Therefore, by comparing this calculated amount of use with the measured value of the amount of replenishment at the time of the previous replenishment, a correction coefficient for the amount of use can be calculated, and the calculation accuracy can be improved. Since a new correction coefficient can be calculated every time the soil improvement material is replenished, for example, even when the calculation accuracy of the amount of use varies with time, the correction coefficient is always set to an appropriate value following this fluctuation. It can be updated and the usage amount can be calculated with high accuracy.

  7 is a mixing device provided on the base frame 2A of the traveling body 2, and the mixing device 7 uniformly mixes the earth and sand conveyed by the conveyor 4 and the soil quality improving material. Here, as shown in FIG. 1, the mixing device 7 is provided in a box-shaped treatment tank 7A provided below the turn-up position of the conveyor belt 4A and opened upward, and rotatably provided in the treatment tank 7A.

In addition, a discharge port (not shown) opened above the discharge conveyor 8 is provided on the lower side of the treatment tank 7A, and the improved soil generated in the treatment tank 7A is transferred from the discharge port to the discharge conveyor 8. Fall into.

  8 is a discharge conveyor as a discharge device provided on the base frame 2A of the traveling body 2, and the discharge conveyor 8 conveys and discharges the improved soil generated by the mixing device 7 to the outside of the vehicle.

  Reference numeral 9 denotes an operation panel mounted on the vehicle of the soil improvement machine 1, and the operation panel 9 is a centralized arrangement of various operation devices for driving the vehicle. A coefficient display device 16, a work history display device 17 and the like are also arranged.

  Next, the control system of the soil improvement machine 1 will be described with reference to FIG. 6. First, reference numeral 10 denotes a transport speed sensor provided on the transport conveyor 4. The transport speed sensor 10 detects, for example, the rotation speed of the conveyor belt 4 </ b> A by rotating a roller or the like, and outputs a detection signal to the controller 15.

  Therefore, the controller 15 stores, for example, the opening area of the conveyance port 3C of the hopper 3 in advance, and the earth and sand conveyed by the conveyance conveyor 4 using the opening area and the detection signal of the conveyance speed sensor 10. The transport amount Wt per unit time can be calculated.

  In this case, since the carry amount Wt per unit time of the earth and sand is likely to vary due to various variable factors, the controller 15 controls the rotational speed N of the rotor 5E according to the calculation result of the carry amount Wt as described later. To do. When detecting the conveyance amount Wt, for example, by detecting the conveyance height of the earth and sand (the height dimension of the earth and sand loaded on the conveyor belt 4A) using an ultrasonic sensor or the like, fluctuations in the conveyance amount and the like are more accurately detected. Can be detected.

  Reference numeral 11 denotes a rotation sensor provided in the supply device 5. The rotation sensor 11 detects the rotation of the rotor 5E and outputs a detection signal to the controller 15. Thereby, the controller 15 can calculate the rotation speed N of the rotor 5E using the detection signal of the rotation sensor 11, and can feedback-control this rotation speed N.

  Reference numeral 12 denotes a remaining amount level sensor as a remaining amount sensor provided in the supply device 5. The remaining amount level sensor 12 is a certain remaining amount (this embodiment) to be replenished by the soil improvement material accommodated in the supply device 5. In this embodiment, for example, it is detected that the amount has decreased to a predetermined remaining amount level L) shown in FIG. 4 and a detection signal is output to the controller 15.

  Here, the remaining amount level sensor 12 is, for example, a casing 12A attached to the top plate 5B of the supply device 5, and is rotatably supported by the casing 12A. The rod 12B extends downward to a corresponding position, and a plurality of blades 12C provided on the distal end side of the rod 12B.

  In this case, a weak rotational force is always applied to the rod 12B by a rotation source (not shown) such as an electric motor housed in the casing 12A. When the soil improvement material replenished in the accommodating portion 5A remains to a position higher than the remaining amount level L, the blades 12C are buried in the soil improvement material, thereby preventing the rod 12B from rotating.

  Further, when the soil quality improving material decreases to a position below the remaining amount level L, each blade 12C is exposed from the soil quality improving material, so the rod 12B rotates together with the blade 12C. Thereby, the remaining amount level sensor 12 detects whether or not the soil quality improving material in the supply device 5 has been used up to the remaining amount level L by the presence or absence of rotation of the rod 12B.

  Reference numeral 13 denotes an alarm as a notification means mounted on the soil improvement machine 1, and the alarm 13 is activated by the controller 15 when the soil improvement material in the supply device 5 reaches the remaining level L. And the alerting | reporting device 13 alert | reports the surrounding workers etc. that the soil improvement material became the residual amount level L by light, a sound (voice | voice), a monitor display, etc., for example.

  Reference numeral 14 denotes, for example, a replenishment amount input device as a replenishment amount input means provided in the operation panel 9 of the vehicle. The amount A is input as a specific numerical value, and the input value is output to the controller 15. Further, as shown in FIG. 7, the replenishment amount input device 14 has an input operation unit 14A in which, for example, numeric keys can be operated, and a display monitor 14B that displays an input value of the input operation unit 14A. ing.

Here, during the soil improvement work, every time the soil improvement material in the supply device 5 is used and decreases to the remaining level L, the alarm 13 is activated and the soil improvement material is supplied. Inform. Then, the worker or the like replenishes the soil improvement material into the supply device 5 at each replenishment timing, and the replenishment amount A at this time is replenished at each replenishment timing A _n (n = 1, 2, 3, ...) is input to the supply amount input device 14 every time.

Thus, for example, actual usage of soil improvement agent that is used during the n-th replenishment timing to the (n + 1) -th replenishment timing, the n-th input in supplemented timing input value of the replenishment amount A _n Is equal to For this reason, the controller 15 calculates the usage amount of the soil improvement material as described later, and compares the calculated value with the input value of the replenishment amount _An for each replenishment timing, thereby calculating the usage amount. Accuracy can be increased.

  Reference numeral 15 denotes a controller as a usage calculation means mounted on the soil improvement machine 1, and the controller 15 is constituted by an arithmetic processing circuit having a storage circuit such as a ROM and a RAM and a timer function, for example. 10. The soil improvement process shown in FIG. 11 is performed. In this case, the controller 15 is connected to the supply motor 6, the sensors 10, 11, 12, the alarm 13 and the replenishment amount input device 14, and is connected to a correction coefficient display device 16 and a work history display device 17 which will be described later. Has been.

  When the soil improvement work is performed, the controller 15 calculates the transport amount Wt per unit time of the sediment using the detection signal of the transport speed sensor 10 and the like, and is supplied from the supply device 5 to the sediment. The amount of use Bt of the soil improvement material to be calculated per unit time is estimated, and the rotation ratio of the rotor 5E is adjusted so that the mixing ratio, that is, the addition rate of the soil improvement material (Bt / Wt) becomes the set value. Control the number N.

  In this case, the use amount Brev (weight) of the soil improvement material when the rotor 5E rotates once is the volume V per rotation of the rotor 5E stored in advance in the controller 15 (that is, when the rotor 5E rotates once). The total volume of the space 5F communicating with the supply port 5G), the specific gravity ρ of the soil improvement material stored in advance, and the correction coefficient α described later can be calculated as in the following equation (1).

Here, the correction coefficient α corrects an error that occurs in the calculated value of the usage amount Brev due to, for example, increase / decrease in the filling rate of the soil improvement material entering into each space 5F of the rotor 5E, variation in the specific gravity ρ of the soil improvement material, etc. This coefficient is calculated every time as the correction coefficient α _n (n = 1, 2, 3,...) Every time the soil improvement material is supplied.

The calculation process of the correction coefficient α will be described. First, the controller 15 performs these operations when, for example, the soil supply material is supplied to the supply device 5 at the n-th replenishment timing and the (n + 1) th replenishment timing is reached. The total number of revolutions ΣN of the rotor 5E rotated during the replenishment timing is measured using the detection signal of the rotation sensor 11. Then, by using the total number of revolutions ΣN and the formula 1 above, the use of the soil quality improving material that is supplied to the earth and sand between the nth replenishment timing and the (n + 1) th replenishment timing The amount B is calculated as the following amount 2 as the usage amount _Bn .

This usage amount _Bn represents the usage amount B of the soil improvement material used after the nth replenishment timing. Here, when the usage amount of the soil improvement material is calculated without correction, the calculated value is a value (B _n / α _n ) obtained by dividing the formula 2 by the correction coefficient α _n . Therefore, as shown in Equation 3 below, the actual usage amount used between the value (B _n / α _n ) without correction of the usage amount and the nth replenishment timing to the (n + 1) th replenishment timing. The deviation (ratio) between (that is, the replenishment amount A _n ) can be calculated as the correction coefficient α _{n + 1} used at the next replenishment timing.

As described above, the controller 15 can calculate the latest correction coefficient α used for calculating the usage B at the next replenishment timing every time the soil improvement material is replenished. The amount of use _Bn of the soil improvement material can be always accurately calculated every time. Then, by using the use amount _{Bn and the} like to determine the use amount Bt of the soil improvement material per unit time, the mixing ratio (Bt / Wt) of the use amount Bt of the soil improvement material and the transport amount Wt of the earth and sand is obtained. This can be controlled with high accuracy so as to be a predetermined value.

Furthermore, the controller 15, by storing and holding a supply amount A _n of each supply timing and amount B _n, as shown in the following formula number 4 number 6, the constant all supply amount A _n time Calculated as the difference between the total value A0 added over the entire work every day or the total value B0 obtained by adding all the used amounts _Bn over the entire work every fixed time or the day, and the total values A0, B0. The remaining amount C of the soil improvement material to be obtained is calculated as necessary, and these data are output to the work history display device 17 described later.

  Next, reference numeral 16 denotes a correction coefficient display device provided on the operation panel 9. The correction coefficient display device 16 is, as shown in FIG. The contents such as the correction coefficient α are displayed, and the fluctuation state of these values and the correction coefficient α is confirmed.

In this case, the correction coefficient display device 16 includes a replenishing amount display unit 16A that displays the amount to be used from the input value equal to the previous supply of the previous supply amount A _n, to the current supply timing from the previous replenishing timing A usage amount display unit 16B that displays the calculation usage amount B _n during the period, a correction coefficient display unit 16C that displays the correction factor α _n currently in use, and the next correction factor α _{n + 1} are displayed as update values. An update value display unit 16D and a selection button 16E for selecting whether or not to actually use this update value as the next correction coefficient are provided.

For example, when the soil improvement material is regularly replenished at each replenishment timing and the update correction coefficient α _{n + 1} is correctly calculated, the “YES” selection button 16E is operated to set the latest correction coefficient α _{n + 1} . Adopted, the value of the correction coefficient α can be updated. Further, when it is determined that the latest correction coefficient α _{n + 1} includes an error due to, for example, a supply delay or a mistake, the “NO” selection button 16E is operated to postpone adoption of the correction coefficient α _{n + 1} . The current correction coefficient α _n can also be used when calculating the usage amount B _{n + 1,} and calculation with the highest possible accuracy can be performed even in the unlikely event.

Reference numeral 17 denotes a work history display device as a display means provided on the operation panel 9, and the work history display device 17 treats earth and sand for every hour obtained from, for example, the amount of sand transport Wt as shown in FIG. and sediment processing amount display unit 17A for displaying the quantity, the amount B _n in supply amount a _n or the replenishing amount display unit 17B for displaying the total value A0 per the predetermined time, also the supply timing in the supply timing Or it has the usage-amount display part 17C which displays the total value B0 for every fixed time, and the residual amount display part 17D which displays the residual amount C of a soil improvement material.

  The display contents of these display units 17B to 17D are updated, for example, at every replenishment timing of the soil improvement material, every fixed time (for example, 1 hour, 2 hours,...), Or the soil improvement work for one day is completed. It will be updated if you do. Thereby, the workers etc. can efficiently check the processing amount of earth and sand, the replenishment amount A (A0), the usage amount B (B0), the remaining amount C, etc. of the soil improvement material as a list by the work history display device 17, By examining the display data, for example, it is possible to easily grasp the excess or deficiency of the soil improvement material with respect to the earth and sand.

  In FIG. 5, reference numeral 18 denotes a container bag (flexible container bag) used for replenishing the soil improvement material. In this container bag 18, for example, a powdery or granular soil improvement material has a predetermined unit weight (for example, 1 ton). When the container bag 18 is carried into the storage unit 5A of the supply device 5 by, for example, a heavy machine or the like, the container bag 18 comes into contact with the cutter in the storage unit 5A and is torn, thereby causing the soil improvement material in the container bag 18 to break. Replenished to 5A.

  The soil improvement machine 1 according to the present embodiment has the above-described configuration. Next, the soil improvement work process will be described with reference to FIG.

  First, when earth and sand to be reformed are introduced into the hopper 3 using, for example, a hydraulic excavator, the earth and sand are transported by the transport conveyor 4. And the soil improvement material according to the conveyance amount of earth and sand is added and supplied from the supply apparatus 5 to the earth and sand which reached the lower side of the supply apparatus 5 when the controller 15 performs the improvement material supply process mentioned later. These earth and sand and the soil quality improving material are agitated in the mixing device 7 to be improved soil uniformly mixed at a predetermined mixing ratio and discharged from the discharge conveyor 8.

In this soil improvement work, the controller 15 first performs various initial settings in step 1 and sets, for example, a correction coefficient α used for the first calculation of the usage amount as α ₁ = 1. Then, when the soil improvement work is performed and the soil improvement material in the supply device 5 is reduced to a predetermined remaining level L, the alarm 13 is activated in step 8 described later.

  At this time, in step 2, an operator or the like replenishes the supply device 5 with a necessary amount of soil improvement material using one or a plurality of container bags 18. Here, for example, when two container bags 18 are used, since 2 tons of soil improvement material is newly supplied to the soil quality supply material for the remaining level L, in step 3, Is input to the supply amount input device 14, and the input value of the supply amount A is read by the controller 15.

  Then, the controller 15 starts measuring the number of rotations of the rotor 5E by the counter in step 4, and in step 5, an improved soil having a predetermined mixing ratio is generated by performing an improved material supply process described later. In step 6, it is determined whether or not the soil quality improving material has decreased to a predetermined remaining level L by reading the detection signal of the remaining level sensor 12.

  If “YES” is determined in step 6, the rotational speed measurement counter is stopped in step 7, the alarm 13 is activated in step 8, and the process proceeds to step 9 described later. As a result, workers and the like around the vehicle can recognize that it has become the replenishment timing of the soil improvement material by the alarm device 13, and thus can start the replenishment work of a new soil improvement material without delay. When it is determined as “NO” in step 6, the improving material supply process is continued until the soil improving material reaches the remaining amount level L.

Next, in step 9, using the total rotational speed ΣN of the rotor 5E from the previous replenishment timing to the current replenishment timing measured between steps 4 and 7, the soil quality improvement between the replenishment timings is calculated according to the equation (2). The usage amount _{Bn of the} material is calculated. In step 10, using the calculated value of the amount B _n, and the supply amount A _n input in step 3, a correction coefficient alpha _n calculated in the previous replenishment timing, the number 3 of the formula Thus, the current (latest) correction coefficient α _{n + 1} is calculated. In step 11, these values are displayed on the correction coefficient display device 16.

Next, in step 12, it is determined whether or not the correction coefficient α is updated to a new value by reading the operation content of the selection button 16E operated by the operator. Then, the correction coefficient α is updated and the process proceeds to Step 15 described later. If “NO” is determined in step 12, the next correction coefficient α _{n + 1} is held at the same value as the current value in step 14.

  Next, in step 15, the total amount A0 of the replenishment amount is calculated by the equation (4), and in step 16, the total amount B0 of the usage amount is calculated by the equation (5). In step 17, the remaining amount C of the soil improvement material remaining in the supply device 5 is calculated. In step 18, the amount of earth and sand treated is calculated based on the amount of earth and sand transport calculated in the after-mentioned improvement material supply processing. In step 19, these calculated values are displayed on the work history display device 17 as necessary.

  Next, in step 20, for example, it is determined whether or not to continue the soil improvement work by detecting the operator's switch operation, etc., and if “YES” is determined, the process returns to step 2 to start the current replenishment work. To do. If it is determined “NO” in step 20, the process ends.

  In this way, the operator puts earth and sand into the hopper 3 and replenishes the soil improvement material every time the alarm 13 is operated, and inputs the replenishment amount to the replenishment amount input device 14. By checking the coefficient display device 16 and operating the selection button 16E, the soil improvement work can be smoothly advanced. During the work, by checking the work history display device 17, it is possible to easily grasp the calculation usage amount and the replenishment amount of the soil improvement material, and to appropriately deal with these differences and the like. it can.

  Next, the improvement material supply process will be described with reference to FIG. First, at step 31, the detection signal of the conveyance speed sensor 10 is read, and at step 32, the conveyance amount Wt of earth and sand per unit time by the conveyance conveyor 4 is calculated using this detection signal.

Next, in step 33, the detection signal of the rotation sensor 11 is read, and in step 34, the rotational speed N of the rotor 5E of the supply device 5 is calculated. In step 35, for example, the amount of soil improvement material used _Bn calculated at each replenishment timing, the timer function of the controller 15 or the like is used to calculate the amount of soil improvement material usage Bt per unit time.

  Next, in step 36, the rotational speed N of the rotor 5E is feedback-controlled so that the addition rate (Bt / Wt) of the soil quality improving material to the transport amount Wt is equal to the set value set by the operator or the like. Then, the process returns at step 37.

At this time, for example, even when an error is likely to occur in the calculated amount of use due to an increase or decrease in the filling rate of the soil improvement material entering the rotor 5E, variation in the specific gravity ρ, etc., this error is corrected by the correction coefficient α _n. Therefore, the correction coefficient α _n can be constantly updated according to the degree of error, so that the use amount Bt of the soil improvement material can always be calculated accurately.

Thus, according to the present embodiment, the soil conditioner 1 is provided with the remaining amount level sensor 12, the replenishment amount input device 14, the controller 15, the correction coefficient display device 16, the work history display device 17, and the like. In the soil improvement work, the supply amount A (A _n ) of the soil improvement material can be input to the supply amount input device 14.

In addition, the controller 15 calculates the amount B (B _n ) of the soil improvement material, and controls the rotation speed N of the rotor 5E according to the calculation result, so that the soil and the soil improvement material are mixed at a predetermined ratio. Can be mixed. Then, the correction coefficient display device 16 and the work history display device 17 input the replenishment amount A and the calculated use amount B calculated by the controller 15 while the soil supply material for the replenishment amount A is used. And can be displayed.

  Thus, the operator can easily confirm the amount of earth and sand processing, the amount of replenishment of soil improvement material A (A0), the amount of use B (B0) and the remaining amount C by using the correction coefficient display device 16 and the work history display device 17 and the like. can do. And when the display of the replenishment amount A and the usage amount B of the soil improvement material is different, it is possible to quickly grasp that the calculation accuracy of the usage amount B is reduced by comparing these display contents. The calculation accuracy of the usage amount B can be increased.

  Therefore, for example, even when the filling rate of the soil improvement material into the rotor 5E, the specific gravity ρ of the soil improvement material, etc. fluctuate, an excessive supply or shortage of supply of the soil improvement material occurs due to errors in the calculation of the usage amount B. Can be reliably prevented. As described above, the replenishment amount and the usage amount of the soil quality improving material can be easily confirmed, and the mixing ratio can be stabilized and the high quality improved soil can be efficiently generated.

  In this case, since the remaining amount level sensor 12 is used, it can be reliably detected by the remaining amount level sensor 12 that the soil quality improving material in the supply device 5 has been reduced to a certain remaining amount level L. Can be set as When the soil improvement material replenishment timing is reached, the replenishment amount of the soil improvement material replenished at the previous replenishment timing, that is, the input value of the replenishment amount A input to the replenishment amount input device 14 and the previous replenishment timing. From this time to the current replenishment timing, the calculated use amount B of the soil quality improvement material should be equal, so that the correction coefficient α can be calculated by comparing these values.

  As a result, the correction coefficient α can be calculated every time the soil improvement material is replenished, and the calculation value of the usage amount B can be corrected by the correction coefficient α. For example, when the calculation accuracy of the usage amount B varies with time. However, the correction coefficient α can always be updated to an appropriate value, and the calculated usage amount B can be prevented from greatly deviating from the actual supply amount A.

  In addition, since the alarm 13 linked to the remaining amount level sensor 12 is provided, when the soil quality improving material in the supply device 5 reaches a certain remaining amount level L, this state is notified by the notification means 13 such as surrounding workers. Can be notified. As a result, it is possible to prevent variations in replenishment timing, forgetting replenishment, and the like, and to perform replenishment work stably.

  Next, FIGS. 12 to 15 show a second embodiment of the present invention, and the feature of this embodiment is that the soil conditioner is supplied with the soil conditioner stored in the external storage. . In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  Reference numeral 21 denotes a soil improvement machine, and the soil improvement machine 21 is roughly constituted by the traveling body 2, the hopper 3, the transport conveyor 4, the supply device 5, the mixing device 7, and the discharge conveyor 8 in substantially the same manner as in the first embodiment. As shown in FIG. 14, a remaining amount level sensor 12, a supply amount input device 14, a correction coefficient display device 16, a work history display device 17 and the like are mounted.

  However, the soil improvement machine 21 according to the present embodiment is supplied with a soil improvement material from a silo 25 described later. Further, the soil improvement machine 21 is equipped with a controller 22 as usage amount calculation means for performing the soil improvement process shown in FIG. 15 in substantially the same manner as in the first embodiment. As shown, a changeover switch 23 for switching the update method of the correction coefficient α to the automatic update mode or the manual update mode is connected to a signal output circuit 24 described later.

  Reference numeral 24 denotes a signal output circuit as signal output means connected to the output side of the controller 22, and the signal output circuit 24 is used when, for example, the soil conditioner in the supply device 5 is used up to a predetermined remaining level. A signal instructing replenishment to be described later is supplied to a replenishing device 27 described later by wired or wireless communication means.

  On the other hand, reference numeral 25 denotes a silo as an external storage erected, for example, at a work site. The silo 25 receives a soil improvement material having a preset weight when a signal is input from the signal output circuit 24. The improved machine 21 is automatically replenished.

  Here, as shown in FIGS. 12 to 14, the silo 25 has a storage unit 26 for storing a soil improvement material, and an electric power source (not shown), for example, and the soil improvement in the storage unit 26. A replenishment device 27 that automatically replenishes the vehicle-side supply device 5 and a replenishment amount of the soil improvement material that is replenished by the replenishment device 27 is measured by weight, for example, and a replenishment amount that outputs the measurement result to the replenishment device 27 A weight measuring device 28 as a measuring means is generally configured.

  And the silo 25 measures the weight of the stored soil improvement material with the weight measuring device 28 as a measurement means, storing the soil improvement material accommodated in the storage part 26 in the replenishment apparatus 27, The measurement result The storage operation is stopped when reaches a preset supply amount. The replenishing device 27 replenishes the stored soil quality improving material from the hose 27A to the vehicle-side supply device 5. As a result, the silo 25 replenishes the supply device 5 with a predetermined weight of the soil improvement material every time a replenishment operation is performed.

  The soil improvement machine 21 according to the present embodiment has the above-described configuration. Next, a method of using the soil improvement machine 21 will be described with reference to FIG.

  First, at the soil improvement work, as shown in FIG. 13, the vehicle of the soil improvement machine 21 is stopped near the silo 25, and the hose 27 </ b> A of the replenishing device 27 is inserted into the supply device 5. In this state, improved soil can be generated by substantially the same processing as in the first embodiment by operating each device of the vehicle while throwing earth and sand into the hopper 3.

  In this soil improvement work, first, various initial settings are made by the controller 22 in step 41. In step 42, the operator operates the replenishing device 27 to set the replenishment amount A (weight) of the soil improvement material to be replenished from the silo 25 to the soil improvement machine 21 in one replenishment operation. The set value is also input to the vehicle-side supply amount input device 14.

  When the soil improvement work is performed and the soil improvement material in the supply device 5 is reduced to a predetermined remaining level, the remaining level is detected by the remaining level sensor 12 in substantially the same manner as in the first embodiment. Detected. As a result, the controller 22 outputs a signal from the signal output circuit 24 to the replenishing device 27 in step 43.

As a result, in step 44, since the soil improvement material corresponding to the replenishment amount A is supplied from the silo 25 to the supply device 5 on the vehicle side, in steps 45 to 51, processing substantially similar to that of the first embodiment is performed. Do. That is, the improvement material supply process is executed in step 46, and it is determined in step 47 whether or not the soil quality improvement material has decreased to a predetermined remaining level. When it is determined as “YES” in step 47, in step 49, the use amount B _n of the soil improvement material is calculated for each replenishment timing using the total rotation number ΣN of the rotor 5E measured in steps 45 and 48. In step 50, the current (latest) correction coefficient α _{n + 1} is calculated. In step 51, the calculation results are displayed.

  Next, in step 52, it is determined whether or not the correction coefficient α is automatically updated by reading the signal of the changeover switch 23. If “YES” is determined, the correction coefficient α is updated in step 53. The process proceeds to step 56 described later.

If “NO” is determined in step 52, whether or not the correction coefficient α is manually updated by reading the operation content of the selection button 16 </ b> E in step 54 in substantially the same manner as in the first embodiment. Determine. If “YES” is determined in the step 54, the correction coefficient α is updated in the above-described step 53, and if “NO” is determined, the next correction coefficient α _{n + 1} is held at the same value as the current in the step 55. In steps 56 to 62, processing substantially similar to that in the first embodiment is performed.

  As a result, the soil condition improving material is automatically supplied from the silo 25 to the supply device 5 by a replenishment amount A every time the soil quality improving material reaches a predetermined remaining level. For this reason, in the state where the changeover switch 23 is switched to the automatic update mode, the operator can smoothly advance the soil quality improvement work simply by continuing to put the earth and sand into the hopper 3, and in parallel with this, the correction coefficient display The replenishment state and the use state of the soil quality improving material can be easily grasped by the device 16, the work history display device 17 and the like. Further, when the changeover switch 23 is switched to the manual update mode, the operation can be performed while confirming the state of the correction coefficient α by substantially the same procedure as in the first embodiment.

  Thus, in the present embodiment configured as described above, it is possible to obtain substantially the same operational effects as those of the first embodiment. In particular, in the present embodiment, since the soil improvement material is supplied using the silo 25 and the signal output circuit 24 that outputs a supply signal is provided to the silo 25, the soil improvement material in the supply device 5 is provided. Is used up to a certain remaining amount level L, the signal output circuit 24 can be operated in accordance with the detection signal of the remaining amount level sensor 12, and a signal for prompting the silo 25 to replenish the soil improvement material is provided. Can be output.

  Accordingly, the soil improvement material having a predetermined weight measured by the weight measuring device 28 can be automatically supplied to the supply device 5 from the silo 25 every time the soil improvement material is supplied. For this reason, it is possible to reliably prevent variations in supply timing, forgetting supply, and the like, and it is possible to efficiently perform the supply work by unmanned.

  In addition, since the correction coefficient α is automatically updated or manually updated according to the switching position of the changeover switch 23, when this is set to automatic update, the value of the correction coefficient α is always updated to the latest without human intervention. It can be updated to a value, and the use amount B of the soil improvement material can be efficiently calculated with high accuracy. Further, in the case of manual update, the value of the correction coefficient α can be appropriately selected as necessary in substantially the same manner as in the first embodiment.

  In the above embodiment, the contact-type remaining amount sensor 12 is provided on the top plate 5B of the supply device 5. However, the present invention is not limited to this. For example, a remaining amount level sensor 12 ′ may be provided on the peripheral wall of the accommodating portion 5 </ b> A of the supply device 5 as in the first modification shown in FIG. 16.
