Description

The present invention relates to a driving machine that penetrates a collection pipe for collecting soil into the soil.

When the specified facilities using hazardous substances are abolished or when ^{the traits of land of 3000 m 2} or more are changed, it is obliged by law to investigate the surface soil at a depth of 50 cm from the ground surface. In order to collect the surface soil used for the survey, a manual soil collector or a soil collector with a drive source such as an electric motor attached to the upper part of the manual soil collector is generally used.

In Patent Document 1, there is a manual type that facilitates excavation work when collecting soil and easy geological inspection of the collected soil, and a soil sampler in which a drive source such as an electric motor is attached to the upper part of the manual type. It is disclosed. The disclosed soil sampler is provided with a cylindrical body having a saw blade-shaped excavation blade at one end of the cylindrical shape and a transmission portion for transmitting a rotational force to the cylinder portion, while rotating the cylinder portion with the excavation blade at the head. In a soil sampler that pushes into the soil and stores the soil inside the cylinder, a feed screw is provided on the inner peripheral surface of the cylinder.

However, when a manual soil collector is used, the work efficiency is lower than when a device equipped with a drive source such as an electric motor is used because the surface soil is collected manually. In addition, in soil containing a large amount of hard gravel, etc., the work efficiency may be further reduced, and the soil may not be collected.

When using a device equipped with an electric drive source, work efficiency is improved, but on the other hand, since the heavy electric drive source is attached to the upper part of the soil sampler, the operability is poor and the burden on the operator is burdened. It will increase and safety concerns will remain. In addition, workers need to keep touching the vibrating soil sampler, which may be restricted in working time due to health and safety considerations.

It is joined through. The pair of fixing plates 2d and 2d are perforated with four through holes 28.

With such a configuration, the base 2 can be made to have a structure having high rigidity as well as being lightweight. Further, by providing the opening space 29a, workability can be improved.

A movable wheel 21 (wheel) capable of changing the traveling direction of the base 2 is attached to the fixing plate 2a on the lower surface side of the base 2, and the fixing wheel 22 whose traveling direction is a fixed direction is attached to the fixing plate 2b. (Wheels) are attached. As a result, the base 2 can go straight and turn.

In a plan view, the position of the center of gravity G of the driving machine 1 is preferably inside the virtual triangle connecting the fixed points of the movable wheel 21 and the fixed wheel 22. Further, more preferably, it coincides with the position of the center of gravity of the virtual triangle. As a result, the driving machine 1 is stably supported by the movable wheel 21 and the fixed wheel 22 without tipping over.

The screw jacks 24 and 24 are fixed to the frame members 25 and 25 in the vicinity of the fixing plate 2b. The screw jack 24 has a structure in which the support shaft 24b can be moved up and down by turning the handle 24a.

By rotating the handle 24a and moving the support shaft 24b downward, the fixed wheel 22 can be lifted onto the ground surface GL, and the support shaft 24b can bear the load of the base 2. As a result, it is possible to prevent the base 2 from moving due to the vibration when the vibrator 5 is driven.

In the present embodiment, a total of two screw jacks 24 are fixed to the frame members 25, 25 in the vicinity of the fixing plate 2b, but it is needless to say that they may be added in the vicinity of the fixing plate 2a.

The outer edge shape of the base 2 in a plan view may be a shape in which an opening space is formed on one side of a rectangle, wheels may be attached in the vicinity of four vertices, and a screw jack may be fixed in the vicinity thereof. This improves the stability of the base 2.

In the present embodiment, the traveling means is a movable wheel and a fixed wheel attached to the lower surface of the base, but as shown in FIG. 6, as a crawler type traveling device 90 having endless tracks 91 attached to both sides of the base 2.

The guide column 3 is composed of a column body 31 and a fixing plate 34 fixed to the lower end of the column body 31. As shown in FIG. 3, the support column main body 31 is a member whose cross section is long in the vertical direction and is composed of a web 33 and flanges 32a and b extending at right angles from both ends of the web 33. There is. The fixing plate 34 is perforated with through holes 36 corresponding to the through holes 28 perforated in the pair of fixing plates 2d and 2d. The guide column 3 is fixed to the base 2 by inserting bolts (not shown) into the through holes 28 and 36 and tightening them with nuts (not shown).

The guide column 3 is preferably made of an aluminum material. As a result, the weight of the guide support column 3 can be reduced.

The slide base 4 is composed of a slide plate 42 which is a rectangular flat plate member and a pulley 44. A total of four pulleys 44, two at each end, are fixed to the surface of the slide plate 42 on the flange 32a side. Further, the groove 44e formed in the pulley 44 sandwiches the flange 32a. As a result, the pulley 44 does not deviate from the flange 32a, and the slide base 4 can slide in the vertical direction along the guide column 3.

The slide base 4 is preferably made of an aluminum material. As a result, the weight of the slide base 4 can be reduced.

A vibrator 5 that vibrates with air is fixed to a surface of the slide plate 42 opposite to the flange 32a by a U-shaped tightening bracket 52. At the tip of the vibrator 5, a male joint portion 54 (combination portion) that fits into the single pipe 56 (collection pipe) is provided. The male joint portion 54 is formed in a cylindrical tapered shape and is tapered, and the single pipe 56 is aligned with the male joint portion 54 so that the male joint portion 54 does not come off from the male joint portion 54 due to the vibration of the vibrator 5. It penetrates into the ground. Further, it is extremely easy to remove the male joint portion 54 from the single pipe pipe 56 after the single pipe pipe 56 has penetrated into the ground.

When the switch 84 is turned on, the compressed air pumped from the compressor (not shown) is supplied via the air hoses 83a, b, and c to open the air valve 88. The compressed air is supplied to the vibrator 5 via the open air valve 88 and the air hose 82. As a result, the vibrator 5 vibrates.

In the present embodiment, a single tube is used as the sampling tube, but a circular tube having a diameter larger or smaller than this may be used, or a square tube may be used.

A rubber stopper 58 (movement limiting means) for restricting the downward movement of the slide base 4 is provided at the position of the lower end of the outer surface of the flange 32a. As a result, the downward movement of the vibrator 5 can be restricted, so that excessive penetration of the single pipe 56 can be prevented, and the vibrator can be reliably penetrated to a predetermined depth.

A flat plate-shaped stop plate 39 (movement limiting device) is provided at the upper end of the support column body so as to project toward the outer surface of the flange 32a.

The raising device 7 (raising means) for raising the vibrator 5 includes an air cylinder 72 driven by air, a belt 74, and pulleys 7a and 7b.

The air cylinder 72 has a mechanism in which the shaft 76 rises and falls due to the pressure of air, and is fixed to the space 37a side of the web 33. The pulley 7a is attached to the end of the shaft 76, and the pulley 7b is attached to the space 37a side of the upper end of the flange 32a. One end of the belt 74 is locked to the space 37a side of the upper end of the flange 32b, the other end is locked to the upper end of the slide base 4, and is further engaged with the pulleys 7a and 7b. There is. Since most of these parts are housed in the space 37a, clothes and the like are hardly caught during the work, and the safety of the work can be improved.

When the switch 86 is turned on, the compressed air pumped from the compressor is supplied to the inside of the air cylinder 72 via the air hoses 83a and d, and the shaft 76 is lowered. At the same time, the belt 74 is pulled into the internal space 37a to raise the slide base 4. As a result, the vibrator 5 fixed to the slide base 4 rises. The ascent stops when the slide base 4 comes into contact with the stop plate 39.

A method of collecting surface soil using the driving machine of the present embodiment will be described.

The driving machine 1 is arranged so that the sampling point is directly below the male joint portion 54. At this time, the lower end of the slide base 4 is in contact with the stopper 58. That is, the vibrator 5 does not move in the vertical direction, but stays at a fixed position near the lower end of the guide column 3. The switch 86 is turned on to raise the vibrator 5. The slide base 4 stops ascending when it comes into contact with the stop plate 39 provided at the upper end of the guide support column 3. The end of the single pipe 56 is moved to the sampling point while passing through the opening space 29a. The switch 86 is turned off, the vibrator 5 is lowered, and the vibrator 5 is fitted with the male fitting portion 54 provided at the end of the vibrator 5. Since the opening space 29a is formed in the base 2 in this way, it is not necessary to pass through the upper surface of the base 2, and the mounting work is simplified.

The handle 24a of the screw jack 24 is swiveled to push down the support shaft 24b, and the fixed wheel 22 is raised on the ground surface GL. As a result, the support shaft 24b is in a state of supporting the base 2, and does not move due to vibration caused by driving the vibrator 5.

The switch 84 is turned on to drive the vibrator 5. A striking force is applied by the vibration of the vibrator 5, and the single pipe 56 penetrates into the ground. After confirming that the lower end of the slide base 4 has come into contact with the stopper 58, the switch 84 is turned off. As a result, the vibration of the vibrator 5 is stopped, and the single pipe 56 does not penetrate into the ground any more.

After confirming the penetration state of the single pipe 56, the switch 86 is turned on to raise the vibrator 5 fixed to the slide base 4, and the male joint portion 54 and the single pipe pipe provided at the tip of the vibrator 5 are raised. Solve the 56 unions.

The ascending is stopped when the upper end of the slide base 4 comes into contact with the stop plate 39 provided at the upper end of the guide column 3. That is, the rise of the vibrator 5 stops.

Move the driving machine 1 from the sampling point and turn off the switch 86. As a result, the air cylinder 72 is opened, and the end portion of the shaft 76 is raised by the tension acting on the belt 74 engaged with the pulley 7a. The vibrator 5 fixed to the slide base 4 naturally descends by its own weight, and when the lower end of the slide base 4 comes into contact with the stopper 58, the lowering of the vibrator 5 stops.

The single pipe 56 that penetrates into the ground is pulled out, and the soil inside is extracted and collected.

The method of collecting soil using the driving machine 1 has been described, but if there is gravel, large stones, etc. in the ground, the single pipe 56 cannot penetrate to a predetermined depth and will be in a state of protruding from the ground. The situation is assumed. Even in such a case, the driving machine 1 of the present embodiment can efficiently pull out the protruding single pipe 56. This method will be described.

The switch 84 is turned off to stop the vibration of the vibrator 5. The switch 86 is turned on to raise the vibrator 5 fixed to the slide base 4, and the male joint portion 54 and the single pipe pipe 56 provided at the end of the vibrator 5 are uncoupled. While passing the single pipe 56 through the space in the opening space 29a, the driving machine 1 is moved to a position where the hydraulic jack can be set. Set the hydraulic jack and pull out the single pipe 56. As a result, the single pipe 56 that has stopped high can be easily pulled out.

Although the present embodiment has been described above, it is natural that various aspects such as modification and addition of the present invention can be carried out without departing from the spirit of the present invention. An embodiment in which a single pipe 56 is penetrated into the soil to collect surface soil using a driving machine 1 has been described, but a plurality of steel pipes are used as sampling pipes instead of the single pipe 56 and are connected in sequence. You may drive it into the ground while doing so. As a result, the driving machine 1 can be used to collect soil having a depth of about 10 m in the ground.
