Description

Technical field

The proposed machine relates to mining, in particular to the development of deposits by an open method and the restoration of areas disturbed by open mining, and can be used when removing the fertile soil layer (PSP).

State of the art

A road milling device is known (https://stroy-podskazka.ru/frezer/dorozhnye-frezy/#h2_852640, read 02/03/2022 at 11.01), including the main unit in the form of a milling drum, a chassis with a frame, a cutter drive, a control module.

The disadvantage of the known device is the inability to extract the fertile soil layer.

The closest device is a milling-auger machine for removing the fertile soil layer and loading it into vehicles (Zenkov I.V. Milling mechanized complexes in quality management systems for reclaimed agricultural land. Monthly scientific and technical production and economic journal COAL, No. 4, 2008 , pp. 67-70), including an excavation milling screw working body, a frame, a running gear, an intermediate conveyor, a transfer hopper, an unloading conveyor.

The disadvantage of the closest device is the low quality of the extraction of the fertile soil layer, with high losses and impoverishment.

Disclosure of invention

The technical result is to improve the quality of the extraction of the fertile soil layer, which reduces losses and impoverishment.

The present technical result is achieved in the device milling auger for removing the fertile soil layer and loading it into vehicles, including an excavation milling auger working body, a frame, a chassis, an intermediate conveyor, a reloading hopper and an unloading conveyor, and an excavating milling auger working body made of composite elements with individual drives, each component is fixed at the edges on rocking arms and hydraulic cylinders with the possibility of changing the cutting line in height when removing the fertile soil layer by each component of the working body, each component has an intermediate conveyor that feeds the removed soil to the reloading the bunker, the unloading conveyor is made with a rotary base with the possibility of turning the conveyor ninety degrees to the right and left of the axis of the machine.

The distinguishing features are:

the excavation milling and screw working body is made of constituent elements with individual drives, each constituent element is fixed at the edges on rocking arms and hydraulic cylinders with the possibility of changing the cutting line in height when removing the fertile soil layer by each constituent element of the working body, this improves the quality of extraction of the CRP, reducing losses and impoverishment;

an intermediate conveyor is installed on each component element, which feeds the removed soil into the transfer hopper, which allows averaging the quality indicators of the PSP when it is fed into the transfer hopper;

the unloading conveyor is made with a swivel base with the ability to turn the conveyor ninety degrees to the right and left of the axis of the machine, such a wide design possibility of the device for excavation and loading into vehicles allows the driver to make optimal decisions to improve the quality of extraction of the PSP.

Comparison of the proposed solution with analogue and prototype did not reveal in them the features that distinguish the proposed solution, this allows us to conclude that the criterion of "novelty" is met.

Brief description of the figure

The drawing shows a diagram of the frontal view of the milling screw working body of the machine, including: 1 - an integral element of the milling screw working body; 2 - the projected line for the removal of the PSP by the machine according to the prototype; 3 - projected losses of the PSP by the machine according to the prototype or declared before the extraction of the PSP; 4 - projected dilution of the PSP with loam by a machine according to the prototype or the claimed loss of the PSP.

Implementation of the invention

The operation of the device of the milling screw machine for removing the PSP and loading it into vehicles is performed in the following sequence. The milling screw machine is installed on the working area along the long side of the rectangle, which makes it possible to have a greater indicator of the operational time for performing the main operation of removing the PSP. When installing the car for loading, the driver starts the conveyor and lowers the constituent elements of 1 milling and screw working body one by one to a design depth of 400 mm, with an individual drive of each constituent element. The work of rock excavation by such a machine is carried out by rotating a wide-cutting working body of a milling-auger type with a width of 6000 mm. The cutter and the screw are combined in one device, both in terms of purpose and functional performance of the work of the working body in the process of removing the PSP. Composite elements are made with a length of 1500 mm. The driver makes the passage forward at the lowest speed and quickly performs adjustments using hydraulic cylinders, lowering or raising the composite elements 1, each of which is fixed at the edges on the rocking levers, with the possibility of changing the cutting line in height, to increase the selective extraction of the PSP at the front of the composite element. The main indicator for adjusting the immersion of the working body is the color of the PSP and the color of the loam that goes behind the soil layer. By means of components 1 along the length of the wide-grip working body of the milling-screw type, the driver adjusts the height and shape of the trapezoidal prism of the removed PSP along the width of the recess, improving the quality of the extraction of the PSP and reducing losses 3 and dilution 4. Next, the driver switches on the optimal operating speed of the machine and removes the PSP . Promptly, according to the state of the color of the rocks in the working out stop, it adjusts the removed strip from the projected line of removal 2 PSP. Intermediate conveyors removed PSP by each component element 1 of the excavation milling and screw working body are fed into the transfer hopper, as a result of connecting several streams into a single volume, the quality indicators of the removed PSP are averaged. The unloading conveyor performs the loading of the PSP from the transfer hopper into vehicles. The conveyor has a swivel base with the ability to rotate ninety degrees, both to the right and to the left of the axis of the milling screw machine, this will allow you to make the best decisions to improve the quality of CRP extraction.
