Abstract

The invention relates to the field of forestry felling machinery, and relates to a felling head feed roller of a combined logging machine, which includes two parts, a twill helical tooth and a roller shaft base, and is characterized in that a plurality of rows of twill helical teeth are arranged in an array around the circumference of the roller shaft body. The invention has the advantages of simple structure, various functions, convenient installation and use, high grinding precision, wide application range and low cost.

Description

Combined logging machine twill spiral tooth feed roller

technical field

The invention relates to the field of forestry felling machinery, in particular to a felling head feed roller of a combined felling machine.

Background technique

At present, with the continuous increase of labor costs, the felling of large quantities of trees in forest farms, farms and municipalities can no longer rely solely on manpower. There is an urgent need for a special logging machine to replace manpower. A series of actions of branching, measuring and peeling. The circumferential working surface of the feed roller of the existing combined logging machine felling head has a straight-toothed surface structure. When processing felled logs, the feeding is unstable and the feeding speed is slow due to the contact surface defects between the circumferential working surface and the felled logs. Work efficiency is low.

Contents of the invention

The purpose of the present invention is to provide a combined felling machine felling head feed roller with simple structure, convenient installation and use, high grinding precision, wide application range, low cost, and can provide felling and peeling functions, which solves the problems in the background technology The disadvantages of slow feeding speed and low working efficiency.

The purpose of the present invention is achieved through the following technical solutions:

The technical features of the oblique spiral tooth structure of the present invention include tooth height, tooth shape, welding contact area, distribution density and the like.

The roller shaft of the present invention needs to cooperate with the twill helical teeth, and a transverse through hole is provided on the side of the shaft.

The horizontal through hole of the roller shaft has the functions of installation and fixation and dynamic balance adjustment.

It can be seen from the above-mentioned technical solutions provided by the present invention that the combined logging machine provided by the present invention has a spike-toothed feed roller. Since the contact area of the arc-shaped surface of the welding part of the nail tooth and the roller shaft is s, the tooth height is h, and the area of the bottom surface of the tooth accounts for 15% of the area of the roller shaft, 11 transverse through holes are provided on the side of the roller shaft. Simple structure, convenient installation and use, high grinding precision, wide application range, stable feeding, various functions, and high operating efficiency.

detailed description

Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

When the nail-toothed feed roller works, the tip of the tooth (as shown in Figure 3) enters the cylindrical surface of the trunk, and its rotation drives the trunk to move stably and quickly in the axial direction, and gradually sheds the bark in the process. Among them, the contact area s of the welding part, the tooth height h, and the distribution density of the nail teeth can be changed according to the actual work requirements.

Due to the adoption of the above structure, the present invention has the advantages of convenient installation and use, high grinding precision, wide application range, stable feeding, fast feeding speed and one-time peeling.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person familiar with the technical field can easily conceive of changes or changes within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
