Description

The invention relates to self-propelled sawmill installations and can be used for sawing logs into boards or beams directly on logging sites, difficult to access due to off-road.

1. Known "sawmill on wheels" (http://www.woodmizer.ru/), which is towed to the place of work by car. The transportation kit for Wood-Mizer machines includes a chassis, a tow bar, a fence perimeter, signal lights, height-adjustable supports, and this ensures a stable position of the machine on an uneven platform. The band sawmill consists of a sawing head, cantilever mounted on a vertical rack with a monorail structure (http: //www.woodmizer/ Sawmill on wheels).

Equipped with a centralized remote control, which displays the control of all the functions of the sawmill. The control console is installed in a location that provides the best visibility and operator convenience.

From this panel, the operator easily controls all the functions of the sawmill, from loading the log to setting the thickness of the board, sawing and the return movement of the sawing head.

However, despite the enormous advantages, this sawmill with such equipment (towing to the place of work with a car) cannot be delivered to a logging site, difficult to access due to impassability.

Also known is a mobile sawmill installation ULP (Center for the processing of wood on a self-propelled caterpillar track "Mobile sawmill installation ULP. Technical description and operating instructions for SFM 00.00.000 TO Birobidzhan, 1992), containing a sawmill, which is a circular saw, mounted on a self-propelled caterpillar truck from a serial rice-harvester. Two circular tables are docked to the circular saw.

A table with a longitudinal groove is installed on the roller tables. The table moves along the rollers of the roller tables from the chain drive.

The sawmill is equipped with pneumatic removal of sawdust. A diesel engine, a bevel gear connected by a cardan, and a cab in which the control knobs of the diesel engine and chassis are located are mounted on the frame of the crawler truck.

The frame of the caterpillar truck serves as the foundation for the circular saw.

Disadvantages of installing a mobile sawmill SFM:

1. It is laborious to prepare it for work and for moving to a new place.

2. During operation, the circular saw vibrates from the action of the springs of the front and rear carriages of the tracked truck.

Object of the invention:

1. To reduce the time for preparation for work and moving the installation of a sawmill self-propelled.

2. Eliminate vibration of the sawmill, such as a circular saw.

The solution is achieved in that the roller table consists of three parts, of which the middle part is rigidly fixed to the frame of the caterpillar truck, and the front and rear parts are pivotally connected to it along the front, while the front and rear parts of the roller table are equipped with double-acting hydraulic cylinders mounted pivotally one end on the caterpillar frame, and the other on the front and rear roller tables. The energy facility has a device for fixing the front and rear carriages with springs relative to the frame of the caterpillar truck, consisting, for example, of a screw with a support, rigidly interconnected, and nuts with support, while the device fixes both carriages with springs simultaneously - front and rear - relatively crawler truck frames.

Thus, the inventive installation sawmill self-propelled meets the criterion of "Novelty."

Signs that distinguish the claimed technical solution from the prototype in other technical solutions of this technical field are not identified, which allows us to conclude that the claimed installation sawmill self-propelled meets the criterion of "significant differences".

Figure 1 shows a General view of the installation of a sawmill self-propelled, left view, working position; figure 2 is the same transport position; figure 3 is the same, in a perspective view, the working position; figure 4 - a device for fixing the front and rear carriages with springs relative to the frame of the tracked cart.

Installation sawmill self-propelled (figure 1; figure 2; figure 3) contains a power tool 1 with a motor unit 2, connected by means of a cardan 3 with a gearbox 4 of the drive of the working bodies, a cabin 5, a caterpillar truck 6 with front 7 and rear 8 carriages with springs 9, while a sawmill with a sawing part is mounted on the frame 10 of the caterpillar truck 6, for example, a circular saw 11 with a roller table, a table 12 with a groove, a support 13, a device 14 for pressing the log 15 against the support 13, the control unit 16, the table moving mechanism 12 with groove and pneumatic system 17 remote Sawdust.

The roller table consists of three parts, of which the middle part 18 is rigidly fixed to the frame 10 of the tracked truck 6, and the front 19 and rear 20 parts are pivotally connected to it along the front, while the front 19 and rear 20 parts of the roller table are equipped with double-acting hydraulic cylinders 21, pivotally mounted at one end on the frame 10 of the tracked truck 6, and the other on the front 19 and rear 20 roller tables.

The energy device 1 has a device 22 (Fig. 4) for fixing the front 7 and rear 8 carriages with springs 9 relative to the frame 10 of the caterpillar truck 6, consisting, for example, of a screw 23 with a support 24, rigidly interconnected, and a nut 25 with support 26 , while the device 22 fixes both carriages with springs at the same time - front 7 and rear 8 - relative to the frame 10 of the tracked truck 6.

A self-propelled sawmill installation (Fig. 2) is delivered to its place of operation on its own thanks to the power unit 1 with a motor unit 2 connected by means of a cardan 3 with a gearbox 4 of the drive of the working bodies.

Energy management 1 is carried out from the cab 5 of the caterpillar truck 6 with front 7 and rear 8 carriages with springs 9, which provide amortization of the sawmill mounted on the frame 10 of the caterpillar truck 6 with a sawing part, for example circular saw 11 with a roller table, table 12 with a groove, a support 13 , a device 14 for pressing a log 15 to a support 13, a control unit 16, a table movement mechanism 12 with a groove and a pneumatic system 17 for removing sawdust.

To move the installation of the sawmill self-propelled, it is brought into the transport position (Fig. 2): the table 12 with a groove is moved to the middle part of the roller table 18, and the front 19 and rear 20 parts of the roller table are raised to the upper position by means of double-acting hydraulic cylinders 21.

Upon arrival of the installation of the sawmill self-propelled to the logging section, it is brought into working position (Fig. 1; Fig. 3): the front 19 and rear 20 parts of the roller table are lowered downward using the hydraulic cylinders 21 so that the front 19 and rear 20 parts the live rolls lay in one horizontal plane with the middle part of the 18 live rolls.

Table 12 with a groove is moved to the front 19 of the roller table.

Between the frame 10 of the caterpillar truck 6 and the front 7 and rear 8 carriages with springs 9 on each side of the caterpillar truck 6, a device 22 is installed, consisting, for example (Fig. 4), of a screw 23 with a support 24, rigidly interconnected, and nuts 25 with support 26.

Screw 23 with support 24 is installed on the front 7 and rear 8 carriages in the middle. Screw nut 25 onto screw 23 and install support 26 on top of nut 25. Unscrewing nut 25 towards support 26, the latter will abut the channels of the frame 10 of the tracked truck 6 and fix both carriages with springs 9 - front 7 and rear 8 - relative to the frame 10 track frame 6.

The installation of the sawmill is self-propelled as follows (Fig. 1; Fig. 3): the log 15 is laid on the table 12 with a groove and is attached using brackets (not shown). Table 12 with a groove moves along the front 19 and middle 18 parts of the roller table and slides on a circular circular saw 11.

Sawing off part of the log 15 due to its movement relative to the rotating circular saw 11, and the log goes to the rear 20 of the roller table.

After that, the brackets (not shown) are removed and the log 15 is laid down with the sawn part on the table 12 with a groove.

In this case, the fastening of the log 15 to the table 12 with a groove is not necessary, since during subsequent passes of the log 15 through the circular saw 11 it is held by the device 14 for pressing against the support 13, which is controlled by a block, from which the movement mechanism (not shown) is also controlled table 12 with a groove and pneumatic system 17 for removing sawdust.

After finishing work on sawing logs 15, the self-propelled sawmill installation is brought into the transport position (Fig. 2), as described above.

Due to the fact that the roller table consists of three parts, the middle of which is rigidly fixed to the frame of the caterpillar truck, and the front and rear are pivotally attached to it, the presence of double-acting hydraulic cylinders allows you to quickly translate the front and rear parts of the roller tables into working and transport positions, reducing the time for preparation self-propelled sawmill installation to work and back.

The presence of a device for fixing the front and rear carriages with springs relative to the frame of the caterpillar cart eliminates the vibration of the circular saw, which contributes to high-quality sawing of the log.
