Definitions

  • the invention relates to a grave vessel with emptying screw.
  • the normal digging containers for excavators, backhoe loaders and loaders have an opening through which the containers are filled and also emptied again.
  • An excavator digging a trench first carries out the digging process with the bucket attached to the boom by pulling the bucket with the boom towards the implement. After the grave vessel is filled, the bucket is tilted so far that no soil falls out of the spoon. The spoon is then raised above the surface of the earth. In the next step, the backhoe is swung to the side. Then the spoon is tilted and emptied. Then the boom is swung back over the trench with the spoon, then the backhoe is brought back into the digging position. Then the spoon is brought back into the trench.
  • the operations listed above start over.
  • the disadvantage of the backhoe bucket commonly used today lies in the many individual operations that are required to loosen the soil in the trench, fill the bucket, place it on the side of the trench and bring the bucket back into the digging position. It is the object of the invention to avoid these disadvantages and to reduce the number of operations.
  • the excavator equipped with the device according to the invention, has finished digging, it lifts the bucket over the surface of the earth and sets the screw in motion. At the same time, he leads the boom with the spoon backwards over the trench above the surface of the earth. During this time, the snail will bww. with appropriate off formation of the screw is emptied on both sides. The higher the spoon is lifted, the farther away the ground pushed out of the spoon by the screw. When the spoon is returned, it is lowered into the trench and at the same time the spoon is brought back into the digging position. Then these processes are repeated. During the digging process, the side wall of the excavated trench prevents the dug ground from falling out of the side openings.
  • the soil can only fall out above the surface of the earth.
  • the device according to the invention is advantageously equipped with a cover plate which covers the opening on the side. This can, for example, be moved upwards over a pivot point by a cylinder and thus open the opening and close this opening again when moving downwards.
  • a cover plate which is rotatably mounted on one side of the opening and which is pressed against the side walls of the opening and held there by a spring or similar means. When the worm is actuated, the spring pressure is overcome by the base conveyed to the outside and the cover plate is thereby rotated about the pivot point, so that the opening is opened.
  • the screw speed for example using a volume regulator
  • the strength of the spring and the height of the spoon above the surface of the earth the distance between the deposit of the soil and the edge of the trench can be determined and, at the same time, excessive soil spinning can be prevented.
  • the screw can advantageously be a paddle axis screw.
  • the screw is advantageously driven via the on-board hydraulics of the carrier device.
  • the snail in the burial vessel can be extended through the opening, for example by means of a screw-on extension part which is about 1 m to 1.20 m long.
  • the excavated trench can be filled again with this extension screw piece will. If the excavated soil is on the side where the excavator is located, a pressure screw is attached, which presses the soil into the trench. If the floor is on the other side, a screw is used. In this case it can be advantageous if there is a free space between the side wall of the grave vessel and where the turns begin on the screw axis, so that the ground is not pressed against the side wall of the grave vessel.
  • the device according to the invention can be designed so that it can be attached to a multi-purpose attachment, such as e.g. was described in European Patent No. 092128, can be grown.
  • a broom, a trench cutter wheel or the drive wheel of a trench cutter chain can be connected to the drive unit from the screw in the digging vessel. This is advantageously carried out via the axis of the screw, which has a hexagon hole on the opening side of the grave vessel. In this hexagon hole, a hexagon bolt is inserted, which is attached to the axis of a broom, to a trench cutting wheel or a drive wheel of a chain trencher.
  • a runner is attached to the back of the spoon, with which the additional filling screw is held in a certain section from the surface of the earth.
  • the cover plate is slightly extended upwards and an adjustable stop is attached to the top of the spoon. This allows the angle up to which the cover plate can open to be regulated.
  • the advantages of the device according to the invention are as follows: The operations of an excavator when excavating a trench are reduced to less than half. An emptying auger in the backhoe saves swiveling away from the trench, dumping the ground and swiveling back to the dig when digging the trench. There is only the digging process and the return of the deep-sea ice over the trench for the next digging process, during this return through the auger, the soil is deposited to the side of the trench. Instead of 3 to 4 work cycles per minute, which can now be carried out with an excavator equipped with a normal backhoe, the excavator can carry out up to 10 digging operations with the device according to the invention.
  • an excavator equipped with the device according to the invention can be more than twice as large Digging performance can be achieved than with the usual deep-bucket. This means that the trenching costs are halved by the device according to the invention. If larger stones, wood or other large-volume objects that cannot be transported by the auger appear during the digging process, they can be picked up and put down on the side just like with normal buckets, as there is still enough space above the auger in the bucket to pick up these items with the spoon.
  • Hydraulically driven excavators, backhoe loaders and loaders with a deep bucket can be equipped with the device according to the invention when digging trenches of smaller dimensions such as e.g. Cable trenches, slowly reverse when working.
  • skids can be attached under the stabilizers, which slide over the ground when digging and driving at the same time and can thus absorb the tipping load during the digging process. By driving and working at the same time, the performance is increased even further, since there is no need to continuously move the excavator or backhoe loader.
  • the material picked up by the shovel can be emptied from the side of the shovel, eg in trenches or in 2 - 3 m high formwork.
  • Can be used for backfilling trenches the bucket is separated from the auger so that only the auger is installed in front of the front loader.
  • the front loader can fill trenches with this screw conveyor, which now serves as a filling screw. With a filling auger, trenches can be filled up to 10 times faster than with a shovel, dozer blade or backhoe of an excavator.
  • the possibility of attaching an inexpensive slip-on screw to the auger in the backhoe is also a great advantage of the device according to the invention.
  • the device according to the invention not only can the trench be dug much more quickly and cost-effectively, but the refill can also be carried out much more quickly and cost-effectively.
  • the broom can be inserted into the hexagonal hole of the screw axis within a few minutes and the road debris can be removed.
  • narrow trenches have to be dug, such as in drainage on sports fields, or if longer trenches have to be dug in the millable soil, it is an advantage if a trench cutting wheel or a chain trencher can be attached to the device according to the invention.
  • the device according to the invention equipped with the additional trench cutter, can convey the excavated soil with the screw located in the grave vessel into the grave vessel, which is then emptied onto trucks.
