Push device used for preventing trees from clamping and pressing saw blade in felling process

Abstract

The invention relates to a push device used for preventing trees from clamping and pressing a saw blade in a felling process. The push device is characterized in that a cross-shaped fixing seat, a support rod and fixing rods are taken as a main body; the two sides of the cross-shaped fixing seat are provided with sliding holes and the fixing rods which are arranged inside the sliding holes in a matching manner and can rotate; an iron chain and a fixing shaft are respectively arranged at the front and rear ends of the cross-shaped fixing seat, the tail end of the support rod is arranged on thefixing shaft in a sheathing manner, and can rotate on the fixing shaft; the front end of the fixing shaft is provided with an adjusting screw nut and a limiting chuck, and fastening screws are arranged between the adjusting screw nut and the limiting chuck to be used for fixed connection; a push screw rod capable of telescopic sliding is arranged inside the support rod, and an inner surface arm ofthe adjusting screw nut is provided with threads to be machined to the push screw rod. According to the push device, through the cooperation of the push screw rod and the support rod, a worker can constantly adjust the pushing force of a V-shaped push hole to prevent the trees from clamping and pressing the saw blade for sawing woods in the felling process, the falling directions of the trees canbe controlled, the installation is convenient, the operation is simple, and the design is ingenious.

Description

technical field [0001] The invention relates to the technical field of logging aids, in particular to a pushing device for preventing trees from pressing against saw blades during logging. Background technique [0002] At present, in logging operations, it is more and more common for people to use saws. People use saws to saw trees to make furniture. Most of the chainsaws used in the market are used for logging. There are also some small trees that are manually pulled by saw blades, but In the process of sawing trees, both the electric saw and the manual saw blade will appear to be pressed against the saw blade by the tree. When the saw blade of the electric saw is pressed, the motor will be damaged; when the saw blade is manually pulled and pressed, It consumes a lot of workers' energy. [0003] There are also many problems that trees will fall when sawing trees. Sometimes it is okay to fall to a place where there are no people. The self-designated direction is tilted, an...

[0002] At present, in logging operations, it is more and more common for people to use saws. People use saws to saw trees to make furniture. Most of the chainsaws used in the market are used for logging. There are also some small trees that are manually pulled by saw blades, but In the process of sawing trees, both the electric saw and the manual saw blade will appear to be pressed against the saw blade by the tree. When the saw blade of the electric saw is pressed, the motor will be damaged; when the saw blade is manually pulled and pressed, It consumes a lot of energy of the workers

[0003] There are also many problems that trees will fall when sawing trees. Sometimes it is okay to fall to a place where there are no people. It can fall in the direction specified by itself, and the saw blade will not be pressed by the tree during the tree sawing process. Therefore, a pushing device for preventing the tree from pressing the saw blade during the logging process is provided.
