Monsieur Pierre, Jean-Marie, Theodore ALLARD "Automatic sinking bucket for drilling purposes"

The present invention relates to an automatic septic tank or - Excavator or a similar drilling device digging boreholes in various - ^ rJTb ^ d ^ ii ^ iötj Boreholes either cased or nienir "cased and, for example, as The foundation or sub-structure can be used for any other purpose can.

There are already different types of sinking bucket became known with a cylindrical body which includes a piston arranged displaceably in this body the end of which one or more shovels or shells suitable for digging or drilling the ground are articulated. Such septic tanks were generally one by one A hoist or a lifting device such as a crane or winch can be actuated Suspended rope and comprised means for controlling or for driving the sliding movement of the piston in the cylindrical body to alternately open the digging shovels and

to cause them to close in order to be able to lift the material removed from the borehole.

Such sinking bucket have a certain number of disadvantages and force the user a certain number of to carry out more or less complicated operations which in particular delay the drilling process *. Moving down or up this bucket is controlled by the rope of a hoist, while it is convenient to control the closure of the blades in the wellbore by some independent means. In the same way, once the bucket was lifted out of the borehole, it was again advisable to open the shovels to be operated in order to discharge the material contained in the bucket. These independent controls of the paddles were made in generally carried out with a rope. The only through the Opening the shovels or at most by slowly unrolling them the emptying process effected by the rope of the lifting device was obviously not very favorable for the removal of the erosion, especially if the blades were dirty or contained sticky or sticky substances such as soft clay or silty sand. So these sticky substances were a hindrance when you got the The drilling process renewed and often fell back into the borehole.

Furthermore, the violent contact of the blades with the soil to be drilled through and in particular caused the sudden contact with the Viaäser often a breakage or tearing of the hoist rope, what the operations to drive up and down this Bucket made much more difficult. Furthermore, the piston was entangled by a Pulley block device which covers most of the The bucket body was actuated, which made this device very sensitive and it stäts in contact with the ablation and with more or less abrasive or wear-causing substances. Because the drive mechanism of the piston is complicated it was prone to wear and tear and frequent failure.

In addition, in certain areas where repeated drilling is carried out, it often happens over time that the Bohrloohsdüa takes on a hemispherical shape. The inner wall of the "borehole tends to be very thin, smooth and hard, so the SöhalUm baw, scoop of the sinking bucket® on the wall hzis, slip and aieh aehliessim öhn ~> Materi Ö0 9'Ö4S / 123 1 bath

* As a result, when performing repetitive drilling operations A large number of these works remain unsuccessful or unusable because no materials are withdrawn from the borehole. From it the result is faster wear or a faster one Wear and tear of the operating equipment because a larger one is necessary Number of drilling operations to be carried out than what is actually required is.

In order to remedy this disadvantage, it was advisable to use the To hold the blades temporarily in the opening position, so these are used as a tool to chop or cut the ground and the honls smooth, essentially hemispherical wall of the Can attack boreholes "

After all, so far only two or three buckets of this type have been found Shovels on what the implementation of a cylindrical borehole ' very difficult. It was practically impossible the perpendicular direction of drilling to comply with what the implementation of the drilling means Piping made necessary.

The present invention addresses all of these disadvantages remedy and refers to an entirely automatic sink bucket which is extremely easy to use and which is particularly effective with or without tubing in all terrains for dry drilling or when drilling in even dusty water.

The inventive automatic sinking bucket with a. includes cylindrical body of a slidable in said body piston at the end of one or mehrere_für_das digging up the ground suitable vanes g arranged gelenkbar, wherein the bucket ttn controlled in a by a lifting rope is attached and control means for the sliding movement of the piston in the cylindrical Body and for the coupled joint movement for opening and closing the blades, is characterized in that the control means for the movements of the blades have a locking bolt which is actuated by the open blades striking the hole ole. the shovels can be closed as soon as a pull has taken place on the hoist rope, whereby Ausklink- * zw. Cooling agents cause the shovels to open and are actuated by pushing the bucket at the end of the drive against a stop that releases the piston in the cylindrical body and at the same time allow the bucket to fall from a certain height in order to push out or detach the bucket in the bucket to effect the abatement contained,

while a locking member in the bucket body is engaged to hold the blades temporarily in the open position when they hit the ground and at least one Automatic chute or gutter removes this removal when the blades are opened, whereby it is caused by the downward or upward movement the bucket is operated.

So you understand that the automatic closing «or. Opening processes the shovels as well as the ejection and the faster removal of the material when they are opened to the invention Bucket maximum efficiency and great simplicity the handiang lend while ensuring excellent fiegeliaässsigkeit in the successive drilling operations. Furthermore, the process of removing the material is only linked to the movement of the bucket itself? it is easy to see that after the removal of the waste material on the blades, which one at the same time dureli the opening of the same and through the sudden pall des Bucket under the action of gravity and along a preset height is effected, the adhering materials, which were thereby easily expelled from the bucket, could be absorbed into the abovementioned laxatives and then, for example, far to be thrown away from the borehole »Every falling back of the spoil into the borehole is thus avoided.

Around this shaft are the actuating means for the piston 2 and swar a drum 5 which loosely around a Sleeve or sleeve 6 which rotates freely around the shaft 4 is arranged, a likewise arranged freely movable around the sleeve 6 Gear 7 and a bolt or pin 8 egg is carried by a part 9 fixedly connected to the sleeve 6.

Chains 10, two in number, according to the one shown Embodiment, can wrap around the sleeve 6 in grooves or recesses 11 at the ends of this sleeve. to produce the straight sliding movement of the piston 2 in the cylindrical body 1. More precisely, the ends are the with the sleeve 6 firmly connected chains 10 on this sleeve by suitable Means such as a flap or fastening part 12 attached (Figure 7) · The ends of the chains connected to the piston 2 are attached to a fixed point 13 of the cylindrical body 1, whereby the chains 10 can wrap around a pulley 14, which rotates around a pin 15 which is in one at the top Peripheral part of the piston 2 provided fork 16 is mounted.

The single rope 17 is on a connection knuckle 18a on the Drum 5 attached. You can see clearly on Figures 7, 11 and 12 that the rope 17 in the upper part 1a of the bucket body by a cable guide forming conventional means 18, and a pulley 19 is guided. The connection thimble 18a is on one Bolt 20 is arranged (FIGS. 6 and 7) which bores 21 formed in a fork and provided in the side jaws of the drum 5 A ring 22, which forms a cable clamp and is provided with a clamping screw 23, is attached to the upper wall 111 of the cylindrical Body 1 put on as FIG. 6 shows.

gene-shaped opening 122. The opening 122 has teeth 121, which form a rack with which a pinion 120 arranged at the end of the pin 8 meshes. A return spring 124 is between one end 125 of the opening 122 and one firmly connected to the part 9 Approach or holder 126 arranged. This spring 124 is applied constantly the pinion 120 around it to a set screw 123 which is mounted at one end of the opening 122 and protrudes into it.

The bolt 8, as clearly shown in Figures 6, T7 and 18 shown, receives through its part 31 a displacement or. Rotary motion in a guide 32 which forms a bearing and is provided in the part 9 firmly connected to the sleeve 6. Besides that a spring 33 constantly acts on this bolt around it in the direction to move onto a corresponding cylindrical recess 34 in the drum 5, namely to move it into a recess 34 inserted ball bearing 35 to introduce. The end of the bolt 8 has an oblique or beveled, an inclined plane forming surface 36, so that this inclined plane can easily be the detachment of the bolt 8 from the drum 6 caused by support on the ball bearing 35, while the remaining part of the bolt end is cylindrical and it is more advantageous to snap it into place and hold it in place of the bolt in the recess formed by the ball bearing 35 34 of the drum.

A rod or the like 38, which according to a specific stroke movement is displaceable in the upper part 111 of the cylindrical Body 1 is arranged, can by a wreath or ring j 39 (Figure 12), e.g. made of cast iron, which are attached to the boom of the lifting device by chains or ropes 40 are held. A spring 41 holds the rod 38 in the upper Location, while a holding or stop forming a stop. Locking ring 4 2: the stroke movement of this rod is limited. Finally acted upon a spring 43 (Figures 11 and 12) the arm 127 of that at 128 is hinged to hold it in a substantially vertical and aligned with the rod 38 position. As a result, when the rod 38 penetrates into one of the notches of the gear 7, is this »lad, .wenn * inWai. the notching has been effected, his Rotary movement in the direction of the arrow F. can end (fig 12) since the laei 128 articulated arm 127 over the successive Battlements tea latch or.

Ultimately, it differs in Figure 12, a second lower ring or ring 20 is attached to the release ring 39 in the middle of the chains 210 is. This second ring 200 is intended to be supported on the upper one during its downward and upward movements Wall 111 of the bucket body an automatic discharge sahurre for to activate the removal, which will be described later ».

With particular reference to Figures 6, 9 and 10, there is a device 101 for temporarily holding the piston 2 visible in the cylindrical body 1. This VerrißgLungs or. Locking device comprises a cylindrical pin 101 which in P one by means of a small support 103 on the lower part 1b of the Bucket body 1 attached bearing 102 is arranged. The pin 101 has ribs, spring wedges, flags or the like on its lower part. 104 to the e.g. diametrically opposed and in a number of Two are. The head of the pin 101 is provided with a cam 105 wedged, for example, on the head of the pin. A return spring 106 is between the end 107 of the cam 105 and a point

108 of the cylindrical body 1 is arranged. The pen 101 and his Flags 104 may or may not be in a corresponding hole

109 which is provided in the upper part 2a of the piston 2 namely according to one of the pin 101 around its perpendicular Axis 101a carried out rotation angle.

^ As can be seen from Figures 6 and 11, there is a cam or a ramp or curve guide 110 on one of the jaws of the Drum 5 mounted in order to cooperate with the cam 105 of the pin 101 during the rotation of the drum.

As can be seen from Figures 13 to 16, the blades are 3 preferably present in a number of yier. Of course an automatic bucket according to the invention could also have a smaller or higher number of blades. The blades are connected to the piston 2 by means of a link 50, which articulated at 52 (Figure 6) on the cylindrical body 1 and at 53 are arranged on the handlebars, so that the upward and downward movement of the piston «2 each closes and opens the Shoveling effects.

It should be noted that, as can be seen from Figure 6, the piston 2 has an inclined inner peripheral portion 54 of the

a counter taper forms to facilitate the downward movement of the lkörper in the Küb _e contained adhering overburden.

The blades 3 consist of a pair of opposite shorter blades 3a and 3, c and a pair of opposite ones longer blades 3b and 3d as shown in Figures 13 and 14. This arrangement enables the soil to be attacked advantageously at two different heights when digging Figures 15 and 16 show a different arrangement of the blades, according to which the four blades -3 have the same length.

The lower part 1a and the upper part 1b_ of the bucket body 1 can be put together in any suitable manner and the upper part 1a can in particular have a certain number of openings or breakthroughs, which are particularly advantageous when drilling in muddy water. The water can thus escape from the bucket body through two openings, which, on the upper part of the same, one on both sides full, the upper wall of the cylindrical body 1 forming part 111 are provided (Figure 8).

FIGS. 19 and 20 explain the manner in which the removal of the debris contained in the bucket body 1 can take place automatically. According to the embodiment shown in these figures, a chute 74 articulated at 75 on the stand or frame or frame of the lifting device 300 comprises an arm 73 forming a lever which is operated by a cable 72 which is connected to another arm at 77, which is also hinged at 76 on the lifting device 300 and is driven by the upward movements of the bucket body 1; I'm limited to stop 78. the lifting movement of the arm 71 under the action of the tension exerted by the return spring 79, which. For example, it can be attached to the stand of the lifting device 300. The chute 74 ", a semi-cylindrical having shape to be placed over the hole 70 and can pass through the cylindrical bucket body 1 during its downward movement in this hole can. Figures 2 \ to 24 .gemäss another embodiments illustrate a chute 202, which has a shape which is particularly suitable for hurling away the debris coming from the bucket body 1. The ropes 201 are attached with their respective ends to the second ring 200 and at a point 204 to the chute, while a return spring 206 is attached to the point 204 connected to a stationary 2-point 205 of the lifting device 300

009846/1231 bad original

det. Finally, as FIG. 5 shows more clearly Chute 202 at 203 at a fixed point of the lifting device 500 hinged.

The way the bucket works and the means of discharge for the ablation which has just been described above is particularly understandable if you refer to the illustrations, among other things 1 to 4 refers.

The only pulling and actuating cable which connects the lifting device 30 to the bucket 1 is initially in a vertical position up to its attachment point on the drum 5 is enough; the operator then operates the HtJqgerät 300 to the open shovels 3 come into contact with the soil. Of course the chains 10 have received their greatest expansion, since the piston 2 is in the lowest or lowest end position is located (Figures 1 and 6).

When the shovels 3 come into contact with the ground, the bucket body 1 is held by it, but when you go through If the rope 17 is released, it can move continue and wind up around the drum 5, there. the helical spring 24 has been biased during the downward movement described above. This winding of the rope 17 is particularly visible on FIGS. 2 and 11. The circulation of the Drum 5 takes place under the action of the spring 24 until the bolt 8 acted upon by the spring 33 (FIG. 6) into the corresponding one Recess 34 of the drum comes into place. This Einklinkungs_ or latching process now couples the rotary movement in a more force-locking manner of the drum with that of the sleeve 6, it should be noted that before the rope 17 is slackened, the piston 2 in the lower position in the bucket body 1 locked by the locking pin 101 is. The blades 3 are thus held in the open position at the time of their impact on the ground. Against and how it will be described later, the piston 2 is automatically unlocked or released during the above-described winding process of the rope.

When the unlocking of the piston 2 has taken place, can the operator lift the bucket by holding a? ! Jug on the rope 17 which the now frictional connection; The drum 5 connected to the sleeve 6 drives exercising l &ss't and so at the same time the winding of the chains 10 around the sleeve and the ascent of the bottom of the blades 3 around the removal

009846 / 13.31 bad original

around causing piston 2 veraflüstils jdb to note that during this Aufwieklühgsvorgang the chains, the actual bucket body remains essentially static al30 quite immobile and the rope 17 unwinds up to a position close to the vertical position of the rope, this position adjustable compared to the vertical position and by the closing of the blades 3 to be ■ - is limited and even to around the removal (Figure 3).

At this point, where the train of the single rope 17 acts on the actual bucket to move the ascent cylindrical body 1 to cause the rod 38 with the wreath attached to the boom of the lifting device39. in touch comes. As you can see in Figure 12, this is coming End 34 of the rod 38 to latch into one of the notches of the gear 7. It should be noted that the gear together with the ™ Drum 5 and the sleeve 6 driven during the previously described ascent movement of the piston 2 and the closing of the blades has been, since the pinion 120 of the bolt 8 is constantly in Engagement with the opening 122 of this wheel remains. By, support the rod 38 against the gear 7 forces the recess 122 or, more precisely, the one provided in this recess and with it Toothed rack 121 meshing with pinion 120 of pin 8, pin 8 to rotate and its ramp-shaped part 36 in working position to bring, sgfäass then and under the action of gravity, this bolt easily emerges from the recess 34 of the Drum 5 can move out. The pinion 120 of the bolt 8 can move in the recess 122 until this bolt is equal to j early turning and retraction movement from the recess 34 has ended. The sleeve 6 is then released from the drum 5 and the simultaneous reverse rotation of the sleeve and the drum takes place each and at the same time the falling of the piston 2 and the opening of the blades as well as the falling of the actual To effect the bucket body 1 until the rope 17 has returned to the vertical position, as FIG. 1 clearly shows. The double Surcharge, which by the. violent and simultaneous downward movement of the piston «and the bucket body is caused by the very easy exposure of the adhering erosion which in this · Body could be included as a result. As on the figure showing the beginning of the triggering of the movement just described When it appears, the second ring 200 is supported on the upper side of the bucket body around the discharge chute for the removal

009846/1231

to set in motion.

Of course, the work cycle just described can be repeated arbitrarily from the point in time at which the removal takes place has been discharged because the blades are open and the rope 17 is in the vertical position.

Bs can therefore be found that a single rope is the up and down Downward movement of the bucket and the control or the Driving the relative rotational movements of the drum around the sleeve, i.e. actuating the opening and closing of the blades causes. In addition, since the, the various control elements bearing shaft 4 is mounted on the upper part of the bucket body, influenced the abrasion contained in the bucket only very little these control members and the bucket itself can without damage in the e.g. A borehole containing water fall down at a speed that can reach ten meters per second.

It should also be noted that the rope 17 can be held in place by the means 22, 23 forming a rope clamp. In · some areas where the borehole has an approximately hemispherical hole shape with smooth walls, it is beneficial to have that To be able to hold the blades in the open position, which in particular enables cutting and drilling work to be carried out with a drill head or a drill bit.

For this purpose, the locking member 101 operates in the following Way. When the piston 2 slides towards the lower part of the bucket body 1, the piston is displaced by the presence of its opening 109 along the pin 101 and that up to deepest shown in Figure 6 and the opening of the blades corresponding binding position of the piston. During this downward movement of the piston 2, the pressure between the cam 105 and the spring 106 located on the bucket body 1 under tension (FIGS. 9 and 10). So as soon as the piston 2 has reached its end position To open the blades, the lugs or ribs 104 move out of the corresponding opening 109 of the piston 2 u.cBee under the action of the spring 106, which tries to set the cam 105, that is to say the pin 101, in rotation. As the flags are no longer in a position aligned with the grooves of the opening 109 of the piston 2, the latter is in the lowest Bndstellung held in the bucket body 1 and the blades 3 on the iünde of the piston 2 are in the open position locked.

009846/1231 bad original

As it is better shown in FIG. 11, if the rope 17 is slackened so that the drum 5 can rotate, the ramp 110 protruding from the drum 5 will come into contact with the crook 105, sc / that the pin 101 with its flags 104 is again in a position aligned with the corresponding hats of the opening 105 of the piston 2. It should be noted that the ramp 110 is offset by approximately 90 ° with respect to the fastening point of the rope 17 on the drum (FIG. 5 ), so / that when the drum 5 is in its end of rotation position after it has rotated about un three quarters of a complete revolution, the ramp 110 is in position A opposite the cam 105. In this way, when the rotary movement of the drum 5 and thus completed the snapping or latching is done, the train is applied to the d cable 17 allow the piston 2 to move upward in the • cylindrical body 1, since the pin 101 in the Verschiebungsst as just described.

It should be noted that the locking of the bolt 8 into the Aueepa "tion 34 very precisely by moving the into the recess 122 protruding screw 123 can be adjusted (Figures 11 and 12).

The removal of the material taken up by the chute 202 (FIGS. 21 to 24) takes place in the following way: At the end of the upward stroke, the upper part 111 of the bucket body 1 lifts the crown. 200 and thus causes the tension of the ropes 201, i.e. the tipping over of the chute 202 under the bucket body. When the blades open, the cuttings fall into the chute 202 (Figures 22 and 23). Finally, when the bucket body 1 has sunk down to drill a new hole, it takes the second rim 200 with it by its downward movement, thus causing the rope 201 to slacken, so that the chute 202 disappears out of the way under the bucket body and around it "The chute 202, acted upon by the spring 206, hurls the material removed from the borehole 70" and moves sideways on the same side (Pigttr 24). Such a flood chute prevents the cuttings from backfilling into the borehole and enables repeated drilling operations to be carried out without hindrance. The drilling work market can therefore be fast and regular «
