Definitions

  • the invention relates to a continuously operating digging conveyor loading attachment for optional use in earth moving machines.
  • discontinuous universal excavators and loaders there are discontinuous universal excavators and loaders and self-propelled, continuously working, but only for one purpose devices, such as. B. Bucket-wheel excavators, Bucket-wheel loaders (U.S. Patent 554671) and Material handling devices (U.S. Patents 2776036 and 2639022).
  • the discontinuous universal excavators and loaders have the advantage of being versatile.
  • the self-propelled, continuously working devices have the advantage of greater digging and loading capacity.
  • the object of the invention is to combine the advantage of the great versatility of the universal excavators and loaders with the great digging or handling performance of the self-propelled continuously working, single-purpose devices and loading devices that economically dig the material to the dump or brings the unloading points.
  • the various release devices - whereby material release devices for loose material can be understood - allow adaptation to different floor and construction site conditions as well as to different carrier devices.
  • the paddle wheel with a foldable blade can be used cheaply on sticky ground.
  • the connection of this bucket wheel with the auger or with a conveyor belt with cutting edge attached to the side is advantageous when attaching to pushers, to existing backhoe equipment from universal excavators and to loaders. In the latter case, the material can be lifted by the paddle wheel.
  • This enables the release device to be attached directly in front of the conveyor belt attached to the side above the front wheel of the loader.
  • the shovel as a release device has an advantage in soils that are interspersed with larger stones. These are picked up as with a normal shovel and set aside.
  • the conveyor device which is equipped with shovels and a support device and thereby simultaneously becomes a release device, is very simple and inexpensive to manufacture.
  • the cutting head works when swiveling and therefore offers advantages at low cutting heights.
  • the ratio of the total content and thus also the dead weight of the release device to the material absorption capacity of this release device is as favorable as possible. Only when this ratio is favorable can the attachment according to the invention be attached to smaller excavators and loaders. With an unfavorable ratio, the performance achieved with the attachment would not be much higher with smaller carrier devices than when working with the shovel. This is the second reason for the development of the release devices listed in claims 16 to 27.
  • an unfavorable relationship between total content and material holding capacity I refer to US Pat. No. 3,230,647, in which a paddle wheel is located behind the display attached flaps is shown.
  • the paddle wheel with foldable blades which was presented in claims 7 and 4, has a more favorable ratio.
  • the design-related ratio of total content to material holding capacity is approximately 10 to 3.
  • this ratio is 10 to 9.
  • Weight as with the bucket wheel of US Pat. No. 3,230,647 three times the performance can be achieved, or in relation to the weight of the basic device required, a much smaller excavator or loader with approximately three times less tipping load can be used to achieve the same performance as with one Paddle wheel according to US patent 3230647.
  • the conveyor belts known according to the prior art were also only suitable to a limited extent for attachment to universal excavators and loaders, since they were too wide in relation to the digging performance of the release devices.
  • State-of-the-art box-shaped conveyor belts could not be used because the upstanding sides of the end roller would have prevented the conveyor belt from being able to be attached directly in front of the paddle wheel.
  • the capacity of these tapes in relation to their dimensions was also insufficient. This is why the box-shaped 3-belt conveyor device was developed, with a conveyor belt standing vertically or at a steep angle on each side of the horizontally running conveyor belt.
  • connection between the two lateral and the horizontal conveyor belt can take place by pushing the upper run of the horizontally running conveyor belt into the lateral conveyor belts forming a wedge or by wedging on the lateral conveyor belts vulcanized belts onto which the weight of the load presses the upper run of the horizontal conveyor belt.
  • Hooks and eyes - Velcro or zippers and similar devices can also be used as connecting elements.
  • the connection is brought about by the convergence and the opening by the divergence of the baths on the end rollers.
  • the advantage of the box-shaped three-belt conveyor belts is that they achieve the cheapest volume in relation to the height and width of the conveyor belts and thus also the cheapest weight ratio of the supporting structure to the weight of the material to be conveyed.
  • the conveyor belt device according to the invention becomes a very compact device which is particularly to be used for mounting on standard construction machines.
  • An essential feature of the invention is the loading device, which can be both a loading device for vehicles and an unloading device for depositing the dug material on dumpers.
  • the loading conveyor belt is mounted on a holder which is attached to the undercarriage, or can be held in a certain position by means of an electronic-hydraulic control, in addition to the rotating device, the advantage is that the superstructure the release device can be pivoted at work, while at the same time loading the vehicles from the loading conveyor belt, which is fixed in a certain position.
  • the loading device additionally consists of a holder with a rotating device attached to the emitting end of the loading conveyor belt, which holder is designed such that it can be mounted on a crawler or wheel tractor. If longer distances to the unloading point have to be covered, the loading device can consist of several conveyor belt bridges connected in series with holding and rotating devices which are supported on caterpillars or wheel tractors.
  • a further embodiment of the loading device as an unloading device for the unloading of the material on tipping means comprises the conveyor lying on the superstructure of the excavator or on a loader or on a tractor or on a supporting device attached behind the tractor or loader, designed as a conveyor belt bridge, a holder with rotating device, which is mounted on a caterpillar, coupled to a rail track conveyor belt rails, in addition, it may include an unloading device, the z. B. may consist of a holding device on which the end conveyor belt rail is placed, or a holding device with a rotating device on which a rail or the end of the incoming rail track lies and at the bottom of the rotating device another conveyor belt bridge, the second end of which is held by a caterpillar is mounted. Through this caterpillar, the end of the loading device is led to where the material is to be unloaded on the dump.
  • the same embodiment can also be used for the reception and loading of bulk materials, e.g. B. of bulk storage bins on ships.
  • the conveyor belt rails used in the loading device are conveyor belt devices of a certain length, e.g. B. of 10, 15 and 20 meters, which are coupled together like railroad tracks. They are laid on the floor or on racks and, with reinforcements, also used as conveyor belt bridges. They are easy and quick to transport, lay and load and are therefore particularly suitable for short-term construction sites. Particularly inexpensive as part of the charging process Direction are 3-belt conveyor belt tracks. They do not become tired at the transfer point between the rails, as with normal conveyor belt rails. The material can slide over the plate of the bridging device (53) without impairing the flow. Compared to other conveyor belt rails, these rails are characterized by their compactness and high performance. In relation to belt lines, they are much more flexible.
  • the attachment can be quickly converted into a stacker by means of devices.
  • An electronic program control of the excavator hydraulics has the advantage that all movements can be optimally adapted and carried out relatively quickly while the driver is relieved.
  • the advantages of the attachment according to the invention lie in the fact that universal excavators, loaders and push crawlers, in addition to their versatile application possibilities, can now achieve digging performance four to ten times greater than when working with the buckets.
  • a universal excavator of approx. 20 tons has a digging capacity of approx. 130 to 150 m3 / h. Equipped with the attachment according to the invention, 600 to 800 m3 / h can be achieved. If the universal excavator is additionally equipped with a 300 HP hydraulic unit, this 20 ton excavator can dig 1,500 to 2,000 m3 / h. Equipped with a loading device made of conveyor belt bridges, carried by caterpillars and conveyor belt rails, earth movements can be carried out four to five times cheaper than in excavator-dumper operation.

  • the displaceability of the receiving conveyor belt (1) into one another or, in the case of two separate conveyor belts, as shown here, against one another, enables the length of the conveyor belt to be adapted to any movement of the permitted with guide plates (9), which is mounted on the superstructure (18) via a connecting frame (15) ) of the universal excavator. Also attached to this connecting frame are the rotating device, in the horizontal direction of rotation (11), and the rotating device, in the vertical direction of rotation (12), for the loading conveyor device (4), which has one end mounted on this rotating device.
  • the loading conveyor belt equipped with a guide plate (8), is held by a holder (20) which is attached to the undercarriage (19).

  • This makes it possible to guide the holder and with it the loading conveyor belt around the excavator independently of the superstructure. It can be supported longer loading conveyor belts, which z. B. is advantageous for settling work, and the conveyor belt can be brought to the rear for transport.
  • the material is conveyed from the unloading conveyor belt into a chute (61). This chute is moved around a suspension point by means of a hydraulic cylinder (65) in such a way that material can be unloaded either in one or in the other by two tippers standing side by side.
  • the universal excavator is equipped with an additional hydraulic unit (57) behind the uppercarriage.
  • the attachment is connected to the excavator via socket bolt connections (24, 58, 23) and hydraulic couplings. This means that the attachment can be quickly replaced with other equipment.

  • This holding device can also be designed so that it only comes from the lower rotating device (74, 78, 64) or the lower rotating device and the upper rotating ring (75) or the base plate and the upper rotating device and either the upper rotating ring or the base plate or the lower rotating ring is equipped with a receiving device for a conveyor belt.
  • FIG. 15 shows two box conveyor belt rails (51) as part of a loading device.
  • the conveyor belt rails consist of a frame with longitudinal tubes (160), cross tubes (14) and vertical tubes (10).
  • Two vertical conveyor belts (7) and a horizontal conveyor belt (6) are attached in the frame.
  • Fig. 15 further shows the upper run of the horizontal conveyor belt, the lower run of the vertical conveyor belts (161), the end rollers (162) of the horizontal conveyor belts, which lie opposite each other, and the holders of these end rollers (163) and the end rollers (164) of the vertical standing conveyor belts.
  • the two conveyor belt rails are connected by a socket-bolt connection.
  • the upper and lower bushing (49) is connected to the right rail, the middle bushing (50) to the left rail.
  • the two rails are connected by inserting the bolt (165). If the rails are to form a curve, the bolt on the outside of the curve is loosened and a rigid connection is established between the bushes either by means of a connected double bolt or an adjustable connection between the rails by means of two bolts connected by a spindle. Are the rails z. B.
  • the coupling consists, in addition to the bushings welded onto the rails, of two legs, connected at a fulcrum which lies above the connecting line of the two rails, and to which the bushings are attached, in this way that in connection with the bushes (49, 50) attached to the rails each on each leg can create a connection between the leg and rails by means of a bolt.
  • the two legs are connected by a spindle or a similar device. This means that every angle of inclination can be set. With a downward angle of inclination, the pivot point of the legs is below the connecting line of the two rails.
  • a device (53) bridges the space between the upper runs from the opposing conveyor belt rails in the area of the end rollers (166). The material comes from the right and slides over the adjustable plate of the device (53) onto the left outgoing conveyor belt.
  • the holder on which there is a torsion spring, holds the plate and presses it with the end against the upper run of the incoming conveyor belt. The end of the plate acts as a scratch.
  • Similar devices are attached to the sides between the vertical belts in three-belt box conveyor belt rails, and likewise, when the rails are assembled into curves or in inclinations, such devices are attached to the parts which are in each case apart, the plates being displaceable in the longitudinal direction or about a pivot point can.
  • a rail is to be used as a switch
  • the bolt is also removed on one side and the other bolt-socket connection is used as a turning device.
  • a hydraulic cylinder can be attached between the two rail ends, which were separated by removing the bolt, for the movement of the rail.
  • two rollers or wheels can be attached, which run on a support.
