Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device capable of removing stone debris and the like from fields and cleared areas.

Conventional debris removing machines have excavating, loading, and sorting/discharging equipment built into a single frame, and therefore, when transporting this equipment, there is a natural limit to the size of the machine allotment space for each equipment.

Furthermore, since the conventional machine is a completely dedicated machine, all the machines have to be idle when stone debris removal work is not possible, such as during the winter.

Furthermore, when a huge boulder is hit underground, the excavator has limited capacity because it is not a specialized machine, and it is therefore difficult to excavate and remove it.

The present invention was invented to solve the above-mentioned problems, and provides a debris removal device that can dramatically increase work efficiency and also increase the annual operating rate of the machine. Its purpose is to

In order to achieve the above objectives, a self-propelled heavy machine equipped with an excavating and loading device is equipped with a sorting device consisting of a receiving hopper, a vibrating sieve, a discharge conveyor, and an engine generator as a power source mounted on a trolley. When connected, the sorting device can be pulled by the heavy machinery while removing debris. In other words, the excavation loading equipment is separated from the sorting and discharging equipment,
This separate machine is a self-propelled heavy machine that separates and removes soil and gravel while towing a sorting and discharging device.

According to the present invention, by separating the excavating and loading equipment from the sorting and discharging equipment, machines with a large capacity can be used for each function, and a machine with a large working capacity can be obtained. Not only can each device be separated and effectively used as other work equipment, but since the excavation and loading device is a dedicated excavator, it can easily excavate any type of boulder, and it can be used directly. It can be easily loaded onto a truck for transporting debris.

Furthermore, since the excavator and the sorting device are connected to each other at a constant distance, the excavator operator can stably supply earth and sand to the sorting device.

Furthermore, since it is a towed type, there is no need for complex and expensive traveling devices such as tracks or hydraulic drive devices on the sorting device side, and a support mechanism using pneumatic tires with a simple structure is sufficient, making maintenance very easy. It has the characteristic of becoming.

The following description will be given based on the embodiments shown in the drawings.

1 is an automatic heavy machine as a self-propelled excavating and loading machine such as a shovel loader, and a receiving hopper 5;
A sorting and discharging device 10 constructed by mounting a vibrating sieve 6 discharging conveyor 7 and an engine generator 8 as a power source on a chassis, that is, a truck 3, is connected by a connecting rod 2.

The truck 3 of the sorting and discharging device 10 is supported by pneumatic tires 4.

As the vibrating sieve 6, a resonant sieve is used, in which two vibrating sieves arranged one above the other are coupled to each other by an elastic body, and the thus coupled vibrating sieve and another elastic body different from the above-mentioned elastic body are used. A vibrating sieve which is commonly supported by a resonant sieve, and which is constructed so that its classifying surfaces made of bars attached to each vibrating frame lie on the same plane, so that the equal classifying surfaces move in opposite directions. It is.

To explain this specifically, it consists of an upper frame 11 and a lower frame 12, which are arranged vertically with an appropriate interval between them.
Resonant springs (not shown) are attached to the upper and lower frames 1 using connecting rods 17 via cases 16 protruding from each frame.
1 and 12 are connected.

The installation angle of this connecting rod 17 is 30~
It is 60°.

In addition, the leaf springs 18 are fixed to the upper and lower frames 11 and 12 with metal fittings 19 and 19', respectively, so as to be perpendicular to the connecting rod 17. It is installed on a trolley.

The upper and lower frames are driven by an eccentric drive device 13, and the upper and lower frames 11 and 12 of the vibrating body are respectively attached with horizontal beams 20 and 21, and a vertically long plate-shaped plate is attached to the upper surface of these beams. Bars 1a and 2a are attached.

When the upper frame 11 and the lower frame 12 move in opposite directions by the eccentric drive device 13, the bars move in opposite directions in synchronization with the upper frame 11 and the lower frame 12. The bars 1a and 2a are also plate-shaped and form mutually adjacent mesh rods, but since there is no slit restriction in the flow direction of the flat-sized bars and the material passes through the mesh rods, there are corrugations on the sides of the plates. Protrusions a are formed and the slits in the flow direction are regulated by the protrusions a, thereby achieving a sorting accuracy similar to that of woven or punched nets, without impairing the large throughput of bar screens.

Now, for the work, the heavy machine 1 is advanced in the direction of the shovel to excavate the soil in front of the shovel, and the excavated soil is supplied to the hopper 5 of the sorting device by turning the shovel.

The supplied soil is sieved through a vibrating sieve 6 to a size of 30 mm or less.
Separated into mm or larger.

Earth and sand smaller than 30mm fall under the trolley 3 and are returned to the excavated location.

Stone debris larger than 30 mm is transported by a discharge conveyor 7 to a dump truck 9 that is running parallel to this sorting device.
and then disposed of elsewhere.

The vibrating sieve 6 and the discharge conveyor 7 are driven by an electric motor (not shown), and are supplied with electric power from an engine generator.

Specifically, as shown in FIG. 3, the discharge conveyor 7 is designed so that its frame can be shortened and folded when moving to another work place.

As explained above, in the debris removal device of the present invention, the sorting and discharge device 10 is connected to the heavy equipment 1 by the connecting rod 2, so only one operator is required, and moreover, the debris excavated by the shovel is always sent to the hopper 5. Since the excavator and the sorting machine are separate machines, the sieve area for sorting can be increased, making it possible to obtain a very highly efficient debris removal device. It has characteristics.

Moreover, by using a resonant sieve, the vibrating sieve performs sieving by vibrating the bars that are adjacent to each other alternately in the same direction, and in combination with its high porosity, the impact force applied to the raw material is reduced. Because it is strong, it can sieve without clogging and while destroying the crosslinking phenomenon caused by the raw materials.The special shape of the bar itself allows it to be used as a stone debris removal screen without making the particle size coarse. The feature is that it is possible to obtain a device with a large processing capacity.
