DEVICE AND METHOD FOR EMPTYING THE EXCAVATOR EXCAVATOR

DESCRIPTION OF THE INVENTION

The field of technology

Excavator excavator; digging trenches; emptying the excavator dredge; mechanical engineering; constructing.

View the problem

For machine excavation of trenches for plumbing, pipelines and various systems for drainage of water and other installations where it is necessary to lay pipes of smaller diameters in the trench, it is dug with a dredge with a dredger. By digging narrower trenches, less earth is needed to install the installations, which also consumes less energy, and the work itself is significantly cheaper. When digging with narrow excavation dumps, some excavation materials, such as wet loam soil, have difficulty emptying narrow excavation dredges. With the known solutions, the excavation of the excavation dumps is emptied simply by gravity. The earth in the scoop is held by the adhesive force against the inner surface of the excavator dredger, the adhesive force being proportionally dependent on the internal surface of the scoop. The scoop empties due to a gravitational force that is proportional to the scoop volume. When the gravitational force is greater than the adhesive force, the earth peels off and falls out of the scoop. The difficulty of non-emptying the excavator dredger is increased by the trenching of the dredger, since the narrowing of the inner surface does not change significantly and the volume and gravitational force of the excavator vary proportionally with the dredging of the dredger. Due to the above, the sticky soil structure causes clogging or non-emptying of narrow excavation dumps. In case of clogging, excavator dredges must be emptied with hand tools, which in case of frequent clogging will reduce the productivity of the construction machine and consequently greatly slow down the workflow.

The excavation dredger, due to its narrow interior during excavation, e.g. it is constantly waving in the loamy ground, so frequent cleaning is required. With each blockage of the scoop, the work is stopped and the productivity of the construction machine is greatly reduced.

The present invention solves the technical problem of emptying or cleaning the excavator dredger so that the scoop itself is cleaned automatically during the operation of the machine. At the same time as automatic scrubbing, the productivity of the excavator is increased.

The state of the art

In the market or in the literature, the applicant has not been able to find a solution for emptying narrow excavation dredges when, due to the properties of some soils, the soil adheres to the walls of excavation dredgers. It is to be expected that the dredging system for the dredge dumps is offered by the world's leading dredge manufacturers as part of standard or optional equipment, but none of the leading manufacturers has such a system on offer.

When digging material that is glued to the walls, it is an easy solution to use wider excavator scoops, since in this case the volume with the scoop of the captured material increases, and gravitational force greatly helps emptying the scoop. The disadvantage of this solution is that with a wider scoop it is necessary to excavate much more material for the same trench depth.

Description of the new solution

The object of the invention is a device and a method for emptying an excavator dredger, whereby the technical solution is functional, technologically suitable for manufacture, economical, for you for people and nature, and is solid and reliable throughout its intended life. The invention also provides for the rapid installation of an excavator excavator on a working machine.

The object of the invention solves the technical problem of emptying the excavator dredger by emptying or cleaning the inner part of the dredger automatically during the very digging of trenches with a construction machine. The device according to the invention transfers mechanical power from the construction machine to the excavator excavator and ensures the continuous operation of the excavator since the process of emptying the excavator excavator is synchronized with the operation of the excavator. The end result is an increase in the productivity of the excavator, resulting in significant energy and time savings.

An excavation dredger emptying device is installed between the existing rear arm of the machine and the machine engraver, the emptying device being constructed in such a way that a lever pushed by the rear arm of the machine pushes the dumper discharging excavator scoop. The device is designed in such a way that the excavation dredger is emptied automatically and does not require any control by the machine operator. The lever of the scoop emptying device automatically performs its work, controlled by standard backhoe movements of the excavator. The position of the individual moving parts is conditioned by the position of the hydraulic cylinder of the rear arm of the excavator.

The device according to the invention is upgraded to an existing excavator control mechanism consisting of an excavator rear arm, excavator excavator, excavator rear hydraulic cylinder, excavator rear cylinder hydraulic lever, and excavator excavator turning lever.

In the present invention, the damper for discharging the excavator dredger is pushed through a mechanism by which mechanical power is transmitted from the machine to the damper without any additional control. To discharge the excavator dredge, additional energy is consumed only if the adhesive force is overcome. In the case of excavations that do not adhere the soil to the excavator excavator, the additional energy consumed is minimal.

The essence of the invention is explained in more detail below with a description of an embodiment and the accompanying drawings, the drawings being part of the present patent application and the drawings show:

Implementation example:

The device according to the invention is upgraded to an existing mechanism for controlling the excavator dredger, consisting of the rear arm of the excavator 7, the excavator excavator 6, the hydraulic cylinder of the rear arm of the excavator 8, the lever of the hydraulic cylinder of the rear arm of the excavator 9 and the lever for turning the excavator excavator 10.

The existing excavator control system has been completed in such a way that:

- on the lever for turning the excavator excavator 10, an anchorage for the rear arm of the machine to which the lever of the rear arm of the machine 1 is fixed with a bolt 5, is added so that the circular movement of the arm of the rear arm of the machine 1 is enabled

- an excavation boom 6 is to be fitted with a lever for the excavator bucket lever to which the lever of the excavator bucket 2 is fixed with a somber 5 so that circular movement of the lever of the excavator bucket 2 is enabled in the pivot. somika 5, which is mounted through the ear of the excavator dumper 4 emptying flap 4. This enables the circular dumper 4 emptying flap to circulate around the bolt 5 through the bore in the dredger 6.

- a hole is provided at the top of the excavator dredger 6, which allows the installation of additional components of the excavator dredging device and at the same time permits the movement of the added individual parts of the excavator dredging device 6

The added components of the excavator excavator emptying device shown in Figure 1 are: machine rear arm lever 1, excavator excavator lever 2, curved excavator excavator emptying lever 3, excavator excavator emptying damper 4 and catches 5 for connecting individual parts of the mechanism, the catfish being used to

- connecting one end of the lever arm of the machine 1 and the central portion of the excavator bucket 2

- connecting one end of the dredge excavator lever 2 and one end of the curved dredge lever to empty the excavator dredge 3

- connecting one end of the curved lever of the dredge damper 3 and the dredger 4 to allow circular motion for all joints.

In the embodiment, Fe 360 structural steel is used as the additional lever material, and Hardox 400 is used as the material for the hatch to empty the excavation dredger 4.

In the embodiment, the lateral side of the excavation dredger 6 corresponds approximately to the surface area of a quarter circle with a radius of 0.65 m, and the thickness on the inside of the excavation dredger is 23 cm. The excavation dredger 6 in the embodiment has a volume

76.3 liters. The excavation dumper 4 discharge vanes have a dimension of 0.65 * 0.23 m in the embodiment and a thickness of 10 mm.

The installation of the other three straws is done as described above when listing the modifications on the existing dredger control system. Figures 2, 3 and 4 show the connection of the existing excavator control system and the added components of the excavator excavator discharge device. Figures 2, 3 and 4 show the same mechanism at different stages of operation, thus illustrating the movement and operation of the whole mechanism. In Figures 2, 3 and 4, for the sake of clarity, only the back side of the excavation dredger 6 is shown.

Figure 2 shows the position of the individual components when the excavator dredger 6 is full of earth. The hydraulic cylinder of the excavator's rear arm 8 is then pulled out and pushes the lever of the hydraulic cylinder of the excavator's rear arm 9, and this lever rotates the excavator excavator 10, which in turn rotates the excavator excavator 6. As a result, the associated constraints move with the somers 5. Components for the dredging device. In the said position of the excavator arm of the excavator arm 8, the added components of the excavator excavator emptying device are shrunk to such a position that the excavator excavator emptying damper 4 allows ground to enter the excavator excavator 6.

In Fig. 3, the hydraulic cylinder of the rear arm of the excavator 8 is partially extended, which also causes a change in the position of the other components of the device. As a result, the added components of the excavator dredger emptying device begin to expand with each other, and the dredger dumper emptying flap 4 empties the excavator dredger 6 at the appropriate position of the back of the dredger 7.

In Fig. 4, the hydraulic cylinder of the rear arm of the excavator 8 is shrunk, which also causes a change in the position of the other components of the device. As a result, the added components of the excavator dredge emptying device are stretched apart. The excavator dumper 4 emptying flap goes into position to ensure that the dredger 6 is completely emptied.

In the present invention, the damper for discharging the excavator excavator 4 is pushed through a mechanism by which mechanical power is transferred from the machine to the damper itself without any additional control. To discharge the excavator dredger 6, additional energy is used only if the adhesive force is overcome. In the case of excavations that do not adhere soil to the excavator dredge, the additional energy consumed is only necessary to overcome the friction in the added assemblies and to raise the added mechanism is minimal.

It is to be understood that the described solution can also be implemented in a different design that does not alter the essence of the invention.
