Description

The invention relates to logging equipment, in particular to machines for picking up, loading and crushing logging waste.

The well-known jaw loader (A.S. No. 831715, IPC B66F 9/061), designed for crushing logging waste and containing a self-propelled chassis, on the frame of which a rotating boom with a jaw grip is mounted, on the movable and fixed jaws of which between their outer teeth, on a pair of crossbars, crushing working elements - plate knives are installed.

The disadvantage of this device is that it requires a lot of force to ensure high productivity when chopping large diameter bundles of branches.

A device is known (patent No. 2025948, IPC B66F 9/06) comprising a self-propelled chassis, on the frame of which a rotating boom with a jaw grip is mounted, having a movable and fixed jaw with gripping levers. The fixed jaw has grooves in which crushing organs are placed, made in the form of driven chain saws. Each saw is equipped with an individual advance drive.

The disadvantage of this device is the difficulty of servicing the grinding element.

The closest in technical essence is a loader-crusher (patent No. 2798606, IPC B66F 9/06), comprising a self-propelled chassis, on the frame of which a rotary boom with a jaw grip and crushing elements are mounted. The lifting frame comprises a lower fixed and an upper rotary jaw, on which drive shafts with a set of saw blades are mounted on the inside, mounted with the possibility of the upper disks entering a cavity formed by the lower disks and each of them having their own individual drives. The upper rotary jaw is mounted with the possibility of rotation by means of a hydraulic cylinder in a vertical plane.

The disadvantage of this device is the difficulty of its maintenance.

The technical result is an expansion of technological capabilities.

The technical result is achieved by the fact that in the device on the forks of the hydraulic lift a rectangular plate is mounted, with a support and rotary device installed on it, on the inner ring of which a platform in the form of a circle is placed, where at the edge of it load racks are mounted, between which crushing mechanisms in the form of drums with flat knives are installed, wherein both are connected to hydraulic motors with the possibility of counter rotation, and at the top on the load racks a hydraulic jaw grip is mounted, while the forks installed in the guides of the lift have the ability to change position in the vertical plane.

The proposed invention is explained by drawings, where Fig. 1 shows a side view (collecting and crushing operation); Fig. 2 is a side view (mulcher operation); Fig. 3 is a front view.

Machine for crushing logging residues 1 contains hydraulic lift 2, on forks 3 of which plate 4 of rectangular shape is mounted, with support-rotary device 5 installed on it, on the inner ring of which platform 6 in the form of a circle is placed, where on its edge load racks 7 are mounted, between which crushing mechanisms 8 in the form of drums with flat knives are installed, wherein both are connected with hydraulic motors 9 with the possibility of counter rotation, and at the top on load racks 7 hydraulic jaw gripper 10 is mounted, wherein forks 3, installed in guides of lift 11, have the possibility of changing position in a vertical plane.

The process of picking up and chopping up branches is as follows. With the hydraulic jaw gripper 10 folded down, the loader-chopper picks up branches by pushing the forks 3 under the branches. A bunch of branches is formed (Fig. 1). Then, by means of the jaw gripper 10, the bunch of branches is pressed against the chopping mechanisms 8. The chopped branches are poured out onto the ground after the self-propelled chassis 1 moves in reverse. In this case, the device operates as a pick-up and chopper.

After turning the platform 180 degrees, this device can work as a mulcher (Fig. 2).

The use of the proposed jaw loader-crusher allows to expand the technological capabilities in comparison with the prototype, to simplify the conditions of crushing logging waste, as well as the maintenance of the crushing element.

Claims (1)

A jaw loader-crusher comprising a self-propelled chassis, a jaw gripper, crushing organs, distinguished in that a rectangular plate with a support-rotary device installed on it is mounted in the device on the forks of a hydraulic lift, on the inner ring of which a platform in the form of a circle is placed, where cargo racks are mounted on its edge, between which crushing mechanisms in the form of drums with flat knives are installed, both of which are connected to hydraulic motors with the possibility of counter-rotation, and at the top on the cargo racks a hydraulic jaw gripper is mounted, while the forks installed in the guides of the lift have the ability to change position in the vertical plane.
