Abstract

This invention relates to the mechanization of the excavation of minerals by sewage treatment plants. The purpose of the invention is to reduce the dimensions of the excavation harvester across the width of the cutting body (RO), reduce the load on the RO and its drive transmission and increase the durability and reliability of the transmission. The combine includes a frame 1 with guides arranged transversely to the longitudinal axis of the combine, an electric drive, a feed body with a drive and an odd number of POs. The carriages 3 are installed in the guides. Each of the RO includes two cutting discs (RD) 7, a drive in the form of a planetary gear, located in the housing of the PO, an electric motor 8 and is mounted on a cage 3 with the possibility of rotation around an axis one of the RD. By moving the carriages 3 along the guides, the PO is installed on the acc. depth of capture. When the axes of the RD 7 pair are located on the same horizontal line, the thinnest reservoir is excavated, and when placed on the same vertical line, the most powerful layer is drilled. The output shafts of the drive RO are made of different lengths. In this case, RD 7 of each subsequent one from the central RO is located with a shorter distance from the longitudinal axis of the combine. Each RO, except the extreme ones, is equipped with a loading screw 11, the width of which is made within the departure of the output shaft of the RD 7 drive. During the operation of the combine, each subsequent Pick 11 11 loads the products of destruction both before and at its RD 7. 1 z.p. , f-ly, 5 ill. 7S 7 3 46 81 9 15 77 Phi & 1 3 1 f 8 69

Description

eleven

The invention relates to the field of mechanization of the excavation of minerals by refining complexes and aggregates and can be used to excavate both thin and thick layers of minerals.

The purpose of the invention is to reduce the dimensions of the cutting body in terms of the working width, reduce the load on the cutting body and its drive transmission and increase the durability and reliability of the drive and the combine as a whole.

Figure 1 presents the scheme of the excavation combine, top view; FIG. 2 is the same when digging a thin layer, when the axes of all the cutting disks are located in the same horizontal plane, side view; on fig.Z - scheme of the excavation combine, partial section; figure 4 - excavation harvester with the excavation of a powerful reservoir, when the drive gears of paired cutting discs are rotated from the horizontal to the vertical plane, and the axes of the pairs of cutting discs are located in the vertical plane, side view; Fig. 5 shows guide grooves.

The extraction combine comprises a housing (frame) 1 mounted on a conveyor (not shown). On frame 1, by means of guide grooves 2 (Fig. 5), a group of carriages 3 is fastened with an odd number of cutting (executive) bodies with the possibility of moving transversely to the longitudinal axis of the combine with. assistance, for example, jacks A (or otherwise), pivotally connected to frame 1 and carriages 3. Carriages 3 are equipped with turn supports 5, in which cases 6 drives with cutting disks 7 and electric motors 8 can be hingedly mounted. around the axes of the supports 5 by means of jacks 9, pivotally connected to the carriages 3 and the bodies 6 of the executive bodies. The drives (gearboxes) 10 contain two identical output shafts connected kinematically with an electric motor with the same gear ratio, for example, by means of planetary gears (FIG. 3). On these shafts, the cutting disks 7 are rigidly fixed. The axes of the bearings 5 of the rotation of the actuators on the carriages 3 are located with the axis of rotation of one of the cutting disks 7, which are equipped with loading augers 11, except the extreme ones from the group of actuators, with the possibility of joint rotation with

cutting discs 7. The output shafts of the drives 10 cutting discs 7 are made in pairs of different lengths so that a pair of cutting discs 7 of each subsequent to the edges of the executive combine, body from the central one, is located with a smaller distance from the longitudinal axis of the combine.

Extraction harvester works as follows.

The work involves central and executive bodies located to the left or right of it, depending on the direction of movement of the combine along the lava, respectively, from right to left or left to right.

The actuators are installed at an appropriate depth (shoulder) by moving the carriages 3 along the guide grooves 2 (Fig. 3) of the combine frame 1 by means of jacks 4 pivotally connected to the frame 1 and the carriages 3. The actuators set the recoverable thickness of the formation. To do this, by means of jacks 9 pivotally connected to carriages 3 and executive bodies 6, the latter are rotated in a vertical plane relative to the axes of the supports 5 of rotation of the articulated connection of the drive bodies 6 with the cages 3 coaxially with one of the cutting disks 7 of a pair of which are equipped with executive bodies.

Here, the axes of each pair of cutting disks 7 are arranged in parallel horizontal planes, one above the other. When the axes of the pair of cutting discs 7 are located on the same horizontal line, the thinnest fossil layer corresponding to the diameter D of the cutting disk 7 is excavated, while the axes of the pair of cutting discs 7 are on the same vertical line, the most powerful layer is drilled that corresponds to at least two diameters of the 2D cutting disk 7.

The depth of capture of the group of executive bodies is ensured by the fact that the output shafts of the drives of the cutting discs 7 are made in pairs of different lengths so that the pair of cutting disks of each subsequent to the edge of the executive body from the central body is located with a smaller distance from the longitudinal axis of the combine.

Each actuator, extreme chrome, is equipped with a loading screw 11 located coaxially with the support 5 of rotation of the body 6 of the executive body and rigidly connected to the drive-shaft shaft 7 with the drive shaft 7. The width of the pickup of the wheels 11 is made within the output shaft. the subsequent auger loads the products of destruction both before and on their cutting discs.

Each pair of cutting discs 7 operates in its own cutting line and, while rotating and feeding the combine, it breaks down the fossil.

The rotation of the cutting disk 7, which is rigidly fixed on the output shafts of the drive gearboxes 10, such as planetary gear-like mechanisms, is transmitted from the engines 8, which are rigidly connected to the drive gearboxes of the 10 actuators.

Thus, the proposed designs of excavation harvesters provide effective shear destruction of the fossil massif, loading of the destruction products onto the conveyor, reduce to a large extent the load on the cutting body and transmission of its drive due to the use of separate actuators, including the cutting disk, drive and an electric motor, which makes it possible to reduce the dimensions of each cutting body across the working width, to increase the durability and reliability of the transmission of the executive body and the combine as a whole. addition, the proposed design shearer allow power-A rise Sit harvester Res increase .prochnosti transmission elements drive the cutting bodies

and without the use of powerful or super-powerful electric motors, the production of which is at the search stage.
