Description

The utility model relates to woodworking and can find application in the woodworking industry, in particular, for the longitudinal sawing of long wood into boards, to obtain a profile beam.

Well-known machines for sawing logs into boards and for processing logs in two planes. They have either carriages with circular saws moving along a motionlessly fixed log, or motionlessly installed circular saws and a vehicle moving the log relative to the saws. As a rule, these are machines with a horizontal axis of rotation, they are not intended for processing, located at an angle of planes in the logs.

Known sawmill (RF patent No. 2038948, publ. 09/07/1995), including a support frame, which is made with guides located along the plane of the cutting tool, front and rear carriages, mounted for movement along the guides and with supports for the material to be sawed, support drive roller, a drive with a grip on the front of the material to be sawn.

Known saw machine for processing in two planes of logs (RF patent No. 2056274 publ. 03/20/1966), containing the frame, support and clamping device for the log and self-propelled portal mounted on the guides of the frame.

The disadvantages of the known sawing machines are low productivity, high power consumption, the ability to work only if there is a power supply.

Also known is the “Circular log saw machine” (patent for a utility model of the Russian Federation No. 47285, published on 08.27.2005), containing a base having basic elements and grips for installing a log, a portal, guides for moving the beam with saw supports, a horizontal displacement drive saw calipers along horizontal guides of a beam with a caliper displacement motor, as well as a vertical displacement drive with a displacement electric motor located on the beam, the drive for moving the portal with an electric motor is displaced a portal and a control panel with control and management bodies associated with electric motors.

This machine is characterized by low productivity, high energy consumption, design complexity, the presence of several electric motors.

The technical problem, which the utility model is aimed at, is the creation of an economical, convenient and easy to operate and repair a multi-saw sawmill, with increased productivity, with the ability to complete the sawmill not only with an electric motor, but also with an internal combustion engine such as gasoline or diesel.

The technical result that provides a solution to the problem is to increase productivity, reduce energy consumption, the possibility of using a sawmill in places where there is no possibility of connecting to a source of electricity, for example, in the forest.

The technical result is achieved by the fact that the circular sawmill for angular sawing contains a track consisting of rails with jumpers and clamping devices for fastening a log, a support-adjusting unit and a marching mechanism, a self-propelled portal mounted on a track, a carriage with an engine and an angular gearbox, a spar and a control panel with controls associated with the engine, wherein the engine may be an electric or internal combustion engine, and the bevel gear is single-stage with a tooth Ata transmission.

Between the totality of the features and the achieved technical result, there is the following causal relationship.

In contrast to the known analogues, the drive of the saw blades from the engine is carried out through an angular gearbox, which allows the use of only one engine in the sawmill, thereby reducing power consumption and simplifying the design of the sawmill, and the use of an angular single-stage gearbox with gear transmission that distributes power from the engine depending on the load, it is possible to install up to 4 vertical saw blades, thereby increasing the sawmill productivity by several times, and the ability to use a motor Internal combustion ator allows operation directly on the forest.

The proposed utility model is illustrated by drawings, where:

Figure 1 - circular sawmill angular sawing, side view.

Figure 2 - circular sawmill angular sawing, top view.

The proposed circular sawmill for circular sawing includes a rail track 1, including: rails 2, jumpers 3, an electric clamp 4 for fixing a log during sawing, a support and adjustment unit 5 for installing and regulating a rail track, a marching mechanism 6 serving for longitudinal movement along rails 2 self-propelled portal 7, consisting of a frame and a half-frame connected from above by crossbars and mounted on a rail 1, a pusher 8, which serves to push an edged board (beam), a spar 9, which serves as a guide for the transverse movement of the carriage 10, containing the engine 11, which can be an electric or internal combustion engine, and a single-stage angle gear 12 with a gear with installed horizontal and vertical saw blades 13, vertical movement mechanisms 14 of the spar 9 and horizontal movement 15 of the carriage 10, mast 16 , which serves to output wires, and a remote control panel 17, which serves to control the movable parts of the sawmill.

Disk sawmill angle sawing is as follows.

Operators install the log on the rail 1 and after reconciling the position, fix the log with electric clamps 4, while the log is automatically centered.

Using the settings of the mechanisms for vertical 14 movement of the side member 9 and horizontal 15 for movement of the carriage 10, the necessary processing or sawing mode of the log is set. The operator from the control panel 17 connects the sawmill to the mains or starts the engine 11, depending on which engine is installed on the sawmill. When the portal 7 moves in the forward direction, the log is sawn; when the portal moves backward, the collider 8 rests against the sawn board, with the help of which the sawn board (beam) is removed from the fixed log.

To obtain a profile beam, a milling cutter is installed together with the saw blades.

The rotation from the motor 11 is transmitted via a belt drive to a single-stage angular gearbox 12 with a gear transmission, where power is transmitted from the horizontal shaft of the gearbox to the vertical, i.e. is distributed on horizontal and vertical saw blades 13, depending on their load, which makes it possible for the claimed sawmill to work on one engine, allows more efficient use of engine power, which makes it possible to install from 1 to 4 vertical saw blades on the horizontal shaft of the gearbox, thereby increase productivity several times.
