Description

The present invention relates to a mobile simple lumber machine capable of lumbering lumber at a logging site in a forest.

Conventionally, there are circular saw type and band saw type lumber machines that lumber raw wood into plate and square lumber. Electric and engine-driven chain saws are also commercially available for cutting down forest trees and removing logs from twigs. In addition, a sawing machine that uses a saw saw to lumber wood into board or square is also available on the market.
In general, as a preparatory work before sawing raw wood into plate or square, place it on a sleeper or table placed in the required span, measure the outer shape of the main and end gates, and take the shaft and the required number of plates. The position and posture are finely adjusted with a wedge and fixed with a dog nail or the like. Then, either the blade or the raw wood is moved, the blade and the raw wood are cut together, and the lumber is made by sawing.
The following is a known example of a saw mill using a chain saw.
Patent Publication 2003-71801, Name: Presented in FIG. 4 on a small automatic lumber machine. Nagata Manufacturing Co., Ltd. Name: Steel / Logo Sole Mobile Sawmill Catalog. In addition, by bringing a small sawing machine, whether stationary or mobile, to the logging site in the forest and sawing the raw wood into the required plate or square lumber, it is possible to effectively utilize resources, produce efficiency, distribute efficiency, protect the environment of the forest, It is also known to improve.

When trying to make a mobile sawing machine using a commercially available chain saw, the chain saw is made for manual work and does not have an assembly part for other equipment. If an easy place is selected and the assembly location is bad, and if the blade surface is out of position with respect to the direction of the lumber after assembly, the load during manual sawing will increase and abnormalities will occur at the chain saw assembly. Vibration occurs, the slide plate on the guide rail does not move smoothly, and if the posture of the blade cannot be corrected even during the lumbering, the cut surface of the lumbering lumber will be cut. As a result, it takes time to finish the surface of the finished plate material, the expected plate thickness cannot be obtained, and material loss increases.
If you bring a light and compact mobile lumber machine to a logging site in a forest, you will not be able to produce lumber with the same length as the guide rail, and there will be a slight dimensional difference in the logging site where the equipment and space are limited and the scaffolding is poor. In addition, it involves complicated work such as cutting a heavy and dangerous raw log before sawing or shifting the position of an unsawed raw wood set during the sawing.
Four bearings on the lower surface of the slide plate on the guide rails arranged on the table slide and the saw chain saws the log. However, if the straightness and parallelism of the two guide rails that are used as a standard during sawing go wrong during use, the four bearings will compete with the two guide rails, and the movement of the slide plate will deteriorate depending on the location. Therefore, in general, you can purchase a ready-made long product with a table and guide rail integrated, or you can install a guide groove and a fine adjustment mechanism on the table, or use a precise assembly tool to install the guide rail. It is assembled. However, the purchase of off-the-shelf products is limited by the structure of other related devices, and long guide rails can be formed on a long table with a high degree of accuracy, as well as assembly of adjustment mechanisms and precision assembly jigs. Assembling is not easy and cheap.
When sawing raw wood with a mobile sawing machine, a chain saw blade assembled on the slide plate can be pitch-moved to the sawing position with considerable accuracy, and a positioning device that can withstand the sawing load is installed, or on the loading platform. There is a need for a moving position determining device that relatively moves the entire raw wood that is fixed horizontally to the lumber position and withstands the weight of the wood and pitches it with considerable accuracy. Neither mechanism is lightweight, simple and inexpensive.
The driver repeatedly determines and positions the position of the lumber with a chain saw blade or raw wood during sawing at a logging site where the space in the forest is limited and the foothold is also poor. Attention such as is necessary.
In terms of configuration, it is impossible to mount it in a normal van type car, etc. in the state where the pillars and diagonal members are assembled as a whole, and even if disassembled and transported, the mountain road can be brought into the forest logging site manually It is not easy to reassemble until lumbering.
The object of the present invention is to solve the problems of the prior art and to devise the construction of a lumber machine to improve workability at a logging site in a forest.

By removing the fixing brackets such as bolts and hanging brackets, the sleepers can be easily removed, and the blade of the chain saw assembled on the slide plate can be moved to the lumber position. For this reason, there is no need for a device for manually adjusting and positioning the chain saw blade or log at the sawing position every time lumbering is performed, and it is possible to lumber a fixed thickness from the log one after another without worrying about breakdowns and accidents.
By providing two horizontal beams and a leveler that connect between the two support beams, it is possible to prevent the support beams from falling on a substantially leveled ground and maintain the levelness. In addition, the sleeper for raw wood which becomes equivalent to the height from the table on the support beam which removed all of the upper sleeper and the lower sleeper to the blade of the chain saw is provided on the left and right support beams to support the raw wood. Furthermore, by positioning with a wedge and fixing the log with a dog nail, etc., the height of the sleeper for log is not increased unnecessarily, and there is no need to move the log during work, and it is possible to adjust the position repeatedly during sawing. You can work without checking it.
