141 Shield tunneling machine US387937 1982-06-14 US4456305A 1984-06-26 Tadao Yoshikawa
A shield tunneling machine having incorporated therein an earth removing apparatus which comprises a tubular casing having an earth inlet at one end and a closable earth outlet at the other end, and an earth transport conveyor rotatably provided within the casing and comprising a helically twisted strip. Unlike conventional earth removing apparatus which has a screw conveyor comprising a rotary shaft and a screw blade around the shaft, the apparatus can transport and discharge earth containing large solid fragments and therefore performs the desired function even when small in diameter, i.e. in shield diameter.
142 Bunker for tunnel boring US170650 1980-07-21 US4353676A 1982-10-12 Henry V. Mikulich; Richard P. Lehmann
The open topped telescoping bunker body is filled from above and material in the body can be discharged when the tail gate at the rear is opened. A double acting push plate is used to push material through the open tail gate and material falling into the body ahead of the push plate during discharge can be ejected through the open front end of the body ahead of the plow blade. The plow blade levels the material to form a roadway as the skid mounted bunker is pulled forward. The blade can be raised to allow passage of men or material under the body. The push blade moves with and with respect to the moving part of the telescoping body.

The second predetermined feeding pressure is preferrably made slightly higher than the first predetermined feeding pressure.
144 Chain drum for chain conveyors US641326 1975-12-16 US4049112A 1977-09-20 Willy Tyslauk
A chain drum for a chain conveyor, in particular a chain flight conveyor mounted on the cutting jib of a cutter-loader, consists of a split sprocket removably mounted on a non-divided drum which is connected to and rotates together with its shaft. The drum is provided with external teeth which mesh with internal teeth on both sprocket halves. Both sprocket halves are held together by locking disks which extend over shoulders on the sprocket halves, which latter are fixed to the drum by means of circlips or the like.BACKGROUND OF THE INVENTIONCutter-loaders of various designs are known for excavating tunnels, adits and so on, as well as for mining minerals such as clay. A cutter-loader may be provided with a swinging cutter jib, on the free end of which is mounted a rotary cutting drum or the like. The jib may also have a conveyor onto which the broken rock excavated at the face by the cutter drum is loaded in order for it to be carried to the next transporter. The cutting head or drum may be driven by an endless chain which forms part of the conveyor and is equipped with conveying flights, the chain passing around a sprocket mounted on the cutting drum between the cutter picks.In connection with such cutter-loaders and also in connection with scraper-chain conveyors used in mining and tunnelling generally, it is known to construct the chain drum in two halves, each drum half being welded to a sprocket half. By inter-connecting the two drum halves, the sprocket halves are combined to form a single sprocket. The sprockets of these chain drums, whether used for chain driving or return purposes are subject to severe wear. When the sprocket becomes so worn as to be no longer serviceable, both drum halves must be replaced together with the sprocket parts welded thereto. To reduce the high cost of complete replacement, it is known to remove the sprocket halves from the drum parts by flame cutting or machining operations and to replace them with new sprocket halves which are then welded to the drum halves. True alignment of the new sprocket halves is always difficult.SUMMARY OF THE INVENTIONThe object of this invention is to provide a chain drum suitable for use in driving or returning a chain and having a relatively simple design which permits the sprocket to be rapidly replaced.This object is achieved in accordance with the invention by removably mounting a sprocket on a drum which rotates with its support shaft. The drum preferably comprises a one-piece sleeve mounted on the shaft which extends through the sleeve and is supported at both ends in a frame. The sleeve is provided in the vicinity of the sprocket with a ring of external teeth or the like which engage complementary teeth on the sprocket halves. Removable fixtures are provided to hold the sprocket halves tightly on the sleeve.With this layout of the chain drum it is possible to replace worn-out sprocket halves quickly and without dismantling the whole drum. The shaft can be set in usual shaft bearings in the parallel side walls of the conveyor or cutter jib. To remove the shaft quickly when necessary, I prefer to provide at least one of the side walls with an opening for the shaft with a diameter in excess of the sleeve diameter, so that the sleeve can be withdrawn through the wall opening primarily intended for the shaft.Preferably, the sprocket halves are provided with axial shoulders. To hold the sprocket halves on the sleeve it is possible to use substantially cup shaped locking disks which embrace the said shoulders of the sprocket halves. The locking disks are prevented from moving axially along the sleeve, by, for example, slotted circlips or the like. I also prefer to provide rings which are located between the removable fixing devices and locking disks, and which rest on the locking disks, the rings being secured against axial displacement by the same fixing devices.Preferably the sleeve has a step in its outer face; the sprocket halves being mounted in the sleeve section with a larger diameter. Both sprocket halves are best made initially from a single workpiece which is then cut along a diameter. This ensures that both sprocket halves fit accurately to each other.The chain drum provided by the invention is not intended to carry excessive torques and is therefore used with advantage in scraper-chain conveyors, cutter loaders and the like. However, it is also possible to use a chain drum in accordance with the invention as the driving or return drum of slat-, roller-, or round link chains in other conveyors having a single or double centre chain or lateral chains. It is understood that with double chain conveyors and belts the drum is provided with two split sprockets mounted for rapid replacement on a common chain drum in the described manner.
145 Adjustable bucket for an earth boring machine US733483 1976-10-18 US4043600A 1977-08-23 Norman Dean Dyer
An earth boring machine is disclosed that produces a bore in a general axial direction relative to the longitudinal axis of the machine. A rotary head is mounted on the body of the earth boring machine and cutter means on the rotary head contact the face of the bore and loosen material at the face of the bore. The loosened material falls to the bottom of the bore. Buckets positioned on the rotary head are located at a first radial distance from the longitudinal axis of the machine to pick up the loose material at the bottom of the bore. As the rotary head rotates, the buckets are carrried above the bottom of the bore and the buckets are moved to a second and shorter radial distance from the longitudinal axis of the machine to prevent the buckets from interfering with elements of the machine near the roof of the bore.

When the loader is in said lowermost position, said plane defined by said forward edges of said scooping lip is tangent to said crawler track means behind the center of the length of said crawler track means and spaced from said tread before the center of the length of said crawler track means.
147 Spoil removal devices for tunnelling machines US371878 1973-06-20 US3970224A 1976-07-20 Cyril Gordon Chatham; Kenneth Long
For use with a tunnelling shield in which an excavating tool operates within a substantially sealed-off and pressurized region, a spoil-removal device for extracting spoil from the pressurized region comprises a cylindrical chamber which has an inlet port open to the pressurized region and a discharge port which is open to a position outside said region and a multi-compartment rotary member adapted to rotate in said chamber in sealed co-operation therewith, each compartment of the rotary member being arranged to pass said inlet port and said discharge port in turn and being arranged not to be open to both ports at the same time, each compartment being arranged to receive a charge of solid spoil when the compartment reaches the inlet port, the amount of the charge being governed by the angle of slide of the spoil, and to deliver the charge to said position outside the excavating region when the compartment reaches the discharge port, substantially each part of the compartment surface which supports the charge when in the vicinity of the discharge port being arranged to attain an angle to the horizontal which is generally in excess of said sliding angle of the spoil, whereby the compartment tends to empty itself while the compartment is open to the discharge port. The axis of rotation of the rotary member may be at right angles or parallel to the direction of the longitudinal axis of the tunnel being excavated. The device may include a receiver for receiving and supporting solid spoil in front of said inlet port.

A scraper chain conveyor includes a driven chain having links constructed from material that is round in cross section. Flight attachments are pulled by the chain along a conveyor channel that includes at least two channel sections that are pivotally connected together in an end-to-end relation for angular positioning of one of the sections with respect to the other. The channel section, extending downstream of the pivotal connection with respect to the conveying direction, has a downwardly sloping portion commencing from a transverse plane immediately adjacent the pivotal interconnection. The other conveyor section has top guides extending over it along its opposite sides. Each of these guides has one of their terminal ends lying in a transverse plane adjacent to and upstream of the pivotal interconnection between the conveyor sections. The chain intersects the two transverse planes at points and passes between them along an arcuate path, the maximum height of which from a subtending cord through the points of intersection is smaller than one-half the length of a given one of the flight attachments.
