Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that is installed in a compaction machine such as a compactor or various rollers to automatically control the number of compactions by the machine in accordance with soil conditions.

Normally, when this type of machine is used to consolidate roads, dams, reclaimed land, etc., the number of compactions is increased until the actual number of compactions reaches a predetermined number of compactions (the number of times the machine travels back and forth). The driver performs the work while counting.

For this reason, there are many counting errors by the operator, which often causes technical and construction problems such as an insufficient number of rollings or too many rolling rolls.

Therefore, a system has already been developed in which an appropriate number of times of rolling is set in advance and the actual number of times of rolling is automatically counted until the set number of times is reached.

The purpose of this system is to manage the actual number of compactions in order to eliminate counting errors by the driver, and there are problems in ensuring that compaction work that is suitable for the soil conditions is carried out reliably and easily. is left behind.

In other words, this type of compaction effect is greatly affected by the compacted coal in the soil at the site, so unless the number of times of compaction is set based on the compacted coal, under- or over-compacting will not occur. It is extremely difficult to perform optimal compaction work.

This invention was made in view of the above circumstances, and its main purpose is to provide a compaction machine that automatically sets the number of times of compaction to be applied to the compacted coal by inputting information on the compacted coal in the field soil. To provide a frequency control device.

Another object of the present invention is to obtain an actual value by automatically accumulating the actual number of compactions of a compaction machine, or to obtain an insufficient compaction as a result of comparing and calculating the actual value with the set value of the number of times of compaction. An object of the present invention is to provide a compaction number control device for a compaction machine that can display the number of compactions to a driver.

Another object of the present invention is to provide a compaction machine compaction number control device that is capable of issuing a machine stop command when the actual number of compactions of the compaction machine reaches a set number, or automatically stopping the machine. There is something to do.

Therefore, the present invention is characterized in that efficient compaction work suitable for compacted coal in site soil can be carried out smoothly, and too little or too much compaction does not occur.

Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

The device of the present invention is equipped with a compaction machine such as a compactor, and includes means 1 for inputting soil compaction coal information at the compaction site, and a sensor 2 for detecting the actual number of compactions of the machine. It has

The means 1 in the illustrated example comprises a keyboard for inputting information such as the compacted coal and water content ratio of the soil at the site measured in advance to the arithmetic processing means 4 via the interface 3.

On the other hand, the sensor 2 detects the switching frequency of the forward/backward switching control system or the rotation speed of the drive system in the compaction machine,
The detection signal is transmitted to the arithmetic processing means 4 via the interface 6.

The arithmetic processing means 4 is configured as a microcomputer or an analog arithmetic system, and uses input information from the keyboard 1 to set the number of times of rolling of the compaction machine adapted to the compacted coal and water content ratio of the soil. In this case, the arithmetic processing means 4 corrects coefficients such as the water content ratio, and successively retrieves reference data from the memory 5 for setting the number of times of compaction of the compaction machine adapted to the soil compaction dust. .

In addition, the calculation processing means 4, at the same time as setting the appropriate number of times of compaction of the compaction machine as described above, integrates the actual number of compactions of the compaction machine based on the input signal from the sensor 2, and calculates the accumulated value. is compared with the set value of the number of times of rolling pressure.

The arithmetic processing means 4 includes a display means 6 and a recording device 7 as its output devices.

The display means 6 in the illustrated example is composed of a display device, and includes a digital display section 6A and a work stop instruction alarm 6B such as a buzzer or a lamp.

The digital display section 6A displays the actual number of compactions of the compaction machine based on the calculation result of the calculation processing means 4, or the insufficient number of compactions as a result of subtracting the actual number of compactions from the set value of the number of times to be compacted.

Therefore, the machine operator can instantly grasp the rolling work status by checking the numerical values on the digital display section 6A.

The alarm 6B is activated by an input signal from the arithmetic processing means 4 when the actual number of compactions reaches a set value.

As a result, the driver can easily confirm the end point of proper compaction work, thereby preventing under- or excessive compaction.

On the other hand, the recording device 7 includes a printer, an X-Y plotter, etc., and records the work results of the compaction machine. The record is useful for work management of the transom.

In the above embodiment, the soil compaction coal information input means 1 is not limited to the keyboard, but may also be a sensor that directly detects each of the compaction density and water content ratio of the soil on site and transmits the detection signals to the calculation processing means 4. Alternatively, it may be a sensor that transmits a soil compaction detection signal to the arithmetic processing means 4 via a water content coefficient setting device.

Further, according to the present invention, it is also possible to automatically stop the compaction machine at the end of the compaction operation.

In this case, when the actual number of compactions of the compaction machine reaches a set value, a signal output by the arithmetic processing means 4 is transmitted to the control system of the compaction machine, and the machine is automatically stopped by the signal. Bye.

Furthermore, the signal can also be used as a command signal when changing the compaction position in the case of unmanned operation of the compaction machine.

As described above, according to the present invention, the number of times of rolling of the compaction machine is automatically set depending on the degree of compaction behind the site. A good rolling effect can be obtained. .

Furthermore, the actual number of compactions of the compaction machine or the number of insufficient compactions calculated by comparing the number of times with the set number of compactions is displayed, so the operator can check the compaction work status instantly and accurately by checking the display. can be grasped.

For this reason, it is possible to prevent too little or too much rolling pressure beforehand and reliably, and it is possible to carry out efficient rolling work smoothly.

Furthermore, it is also possible to automatically stop the compaction machine by a command signal from the arithmetic processing means when the actual number of compactions reaches a set number.
